DETAILED DESCRIPTION

[0045] Following below are more detailed descriptions of various concepts related to, and implementations of, methods, apparatuses, and systems of electric vehicles. The various concepts introduced above and discussed in greater detail below may be implemented in any of numerous ways.

[0046] The present disclosure generally refers to an electric vehicle. The present disclosure refers generally to a tub of electric vehicle made at least partially via additive manufacturing processes.

[0047] Electric vehicle configurations are commonly used in various applications, such as commercial vehicles, motorsport vehicles, public transport, aviation, and the like. Generally, commercial electric vehicles are built with a body-on-frame architecture (e.g., skateboard chassis), as compared to a monocoque design (e.g., chassis and other components are all integrally formed into one body). Many motorsport vehicles utilize a monocoque design, but the manufacturing process can be time-consuming and expensive. Accordingly, it may be desirable for mass-manufactured electric vehicles, such as commercial vehicles, public transport vehicles, aviation, and the like, to have a monocoque design. The use of additive manufacturing may facilitate mass-manufacturing such electric vehicles.

[0048] Implementations described herein are directed to electric vehicles that include a carbon-fiber nylon, partially 3D printed, monocoque frame.

[0049] Implementations described herein are directed to electric vehicles that include a thermal management assembly formed with the tub to provide thermal regulation to a battery within the electric vehicle. [0050] Implementations described herein are directed to electric vehicles that include a plurality of energy-absorbing impact zones for absorbing energy of impact.

[0051] Implementations described herein are directed to electric vehicles that include a wire harness assembly formed with the tub.

[0052] Implementations described herein are directed to electric vehicles that include a battery assembly formed with the tub.

[0053] Implementations described herein are directed to electric vehicles that include a sensor formed with the tub.

[0054] Implementations described herein are directed to electric vehicles that include a LIDAR sensor formed with the tub.

[0055] Generally, mass-produced vehicles do not utilize carbon-fiber materials for massproduction due to high labor costs, timing, and various other manufacturing challenges. Accordingly, it would be advantageous to provide a means for mass-producing vehicles using carbon fiber and, in particular, mass-producing electric vehicles using carbon fiber in additive manufacturing processes.

[0056] Referring generally to the figures, systems and methods herein are directed to providing a tub (e.g., a body) of an electric vehicle via additive manufacturing.

[0057] FIG. 1 depicts a schematic of an electric vehicle 100, according to an exemplary implementation. The electric vehicle 100 can be a general configuration of an electrically powered unit of transportation. For example, the electric vehicle 100 may be, but is not limited to, a car, electric vehicle, hybrid vehicle, internal combustion engine vehicle, motorcycle, scooter, a truck, a van, a bicycle, an aircraft, an airplane, a helicopter, a boat, or other various onroad or off-road vehicles. As shown in FIG. 1, the electric vehicle 100 can include a front end 120. For example, the front end 120 can be positioned at a front-most point of a forward direction of travel, depicted as arrow 130, when the electric vehicle 100 is operating under normal conditions. The electric vehicle 100 can include a rear end 125. For example, the rear end 125 can be positioned opposite the front end 120 when the vehicle 100 is moving in a forward direction of travel. The electric vehicle 100 can include one or more wheels 115. For example, the electric vehicle 100 can include two wheels 115. The electric vehicle 100 can include three wheels 115, as another example. The electric vehicle 100 can include four or more wheels 115, as yet another example. The electric vehicle 100 can include a commercial or personal vehicle for an end user consumer or member of the public. For example, the electric vehicle 100 can include seating capacity for four, five, or more adults and can include multiple front seats or multiple back seats, as well as storage space.

[0058] The electric vehicle 100 can include an operator cabin 110, shown as cabin 110. For example, the cabin 110 can include a space for accommodating occupants (e.g., users of the vehicle 100). The cabin 110 can include space for accommodating one occupant. The cabin 110 can include space for accommodating two occupants, as another example. The cabin 110 can include space for accommodating three or more occupants, as yet another example. The electric vehicle 100 can include a tub 105. For example, the tub 105 can include the framework, outer skin, or otherwise outer portion of the electric vehicle 100 at least partially visible to an outside user (e.g., a body of the vehicle 100).

[0059] FIG. 2 depicts a perspective view of a portion of the tub 105, according to an exemplary implementation. As shown in FIG. 2, and among others, the tub 105 can include the framework of the electric vehicle 100 that surrounds the cabin 110. The tub 105 can provide support for the electric vehicle 100 and components within the electric vehicle 100. In various examples, tub 105 may not include various components of the vehicle 100 including, but not limited to, windows, windshields, wheels, and/or lights.

For example, the tub 105 can be formed of the composite structure 300 to create a monocoque frame (e.g., a unibody). Each of the layers of the composite structure 300 described in greater detail below may be at least partially formed via additive manufacturing. For example, the composite structure 300 can include a shell 310. The shell 310 can be at least partially formed via additive manufacturing (e.g., 3D printing). For example, the shell 310 can be formed with additive manufacturing using a nylon filament.

[0063] The composite structure 300 can include various other materials applied to, printed with, or placed in between, the first prepreg carbon-fiber layer 320 and the second prepreg carbon-fiber layer 360. For example, the composite structure 300 can include a first epoxy layer 330. The first epoxy layer 330 (e.g., resins, solvents, acrylates, pure epoxy) can be applied to the first prepreg carbon-fiber layer 320 or another component of the composite structure 300 to be formed with the first prepreg carbon-fiber layer 320 and the shell 310, as discussed in greater detail below.

[0066] Each component of the composite structure 300 can be formed together with the shell 310. For example, once each layer is added to the shell 310 either individually or together, the composite structure 300 can be formed (e.g., stamped, pressed, welded) such that pressure is placed on the composite structure 300 to form one singular structure. While the layers appear in one specific order in FIG. 3, in various other examples, the layers may be applied in various orders.

[0073] Generally, with vehicles including a body-on-frame configuration (e.g., chassis and fastened separate components), gaps between the vehicle body and other components, such as the battery, can lead to temperature differences between components during the lifespan of the vehicle. Accordingly, it would be advantageous to provide a battery assembly formed with a portion of the vehicle 100 to address the aforementioned challenges.

In still yet other examples, the thermal management assembly 520 may not include an epoxy layer 540. [0079] The thermal management assembly 520 can enclose a portion of a battery pack. For example, the thermal management assembly 520 can surround a flat-floor battery pack 550, as depicted in FIGS. 5 and 6. The thermal management assembly 520 can enclose the flat-floor battery pack 550 such that the thermal management assembly 520 can protect the flat-floor battery pack 550 from damage, such as debris, liquid, or other environmental conditions that could cause damage to the flat-floor battery pack 550.

[0085] Generally, typical vehicles made of aluminum, steel, or a similar metal, include “crumple” zones near the engine compartment that are designed to deform (e.g., buckle) upon impact to absorb energy and force of impact. These zones, however, are typically designed only for front-facing crashes (e.g., at the front end 120 of the vehicle 100). Accordingly, it would be advantageous to provide multiple energy-absorbing zones throughout the vehicle 100 for absorbing force of impact.

[0086] FIG. 8 depicts a perspective view of a portion of the tub 105, according to an exemplary implementation. FIG. 8 depicts an energy-absorbing impact assembly 800. For example, the energy-absorbing impact assembly 800 can include a matrix material structure 810. The matrix material structure 810 can facilitate absorbing energy of impact (e.g., crash, collision, contact with an object). For example, the matrix material structure 810 can include a honeycomb material with a generally hexagonal shape. The hexagonal shape can improve crash testing results. For example, the honeycomb material can be made from a mixture of filaments, elastomers, resins, or the like to provide elastomeric properties such that the matrix material structure 810 can dissipate energy (e.g., collapse, compress, or otherwise deform) in the event of a collision. For example, the honeycomb material can be made from various 3D printing filaments that include elastomeric properties such as thermoplastic polyurethane or thermoplastic elastomers.

[0087] The matrix material structure 810 can be formed with one or more components of the composite structure 300. For example, the matrix material structure 810 can be formed (e.g., via additive manufacturing, welding, stamping, pressing) with the shell 310 of the composite structure 300. In various other examples, the matrix material structure 810 can be formed with other components of the composite structure 300, such as the first prepreg carbon-fiber layer 320 or the second prepreg carbon-fiber layer 360. For example, the matrix material structure 810 can be formed with the shell 310 via a dual head extruder of an additive manufacturing process. Additional components of the composite structure 300 can similarly be formed simultaneously or separately with the shell 310 and the matrix material structure 810.

[0088] The energy-absorbing impact assembly 800 can be positioned at several locations throughout the electric vehicle 100. For example, the tub 105 can include one or more areas that include space (e.g., pockets, apertures) for the matrix material structure 810 to be added on an interior side of the electric vehicle 100 (e.g., positioned behind the second prepreg carbon-fiber layer 360). The tub 105 can include space positioned towards the front end 120 of the electric vehicle 100 for the matrix material structure 810. For example, the energy-absorbing impact assembly 800 can be located on a left-hand side of the front end 120 of the electric vehicle 100 (e.g., left-hand side of operator moving in a forward direction of travel). The energy-absorbing impact assembly 800 can be located on a right-hand side of the front end 120 of the electric vehicle 100 (e.g., right-hand side of operator moving in a forward direction of travel), as another example. The energy-absorbing impact assembly 800 can be located at a midpoint (e.g., center) of the front end 120 of the electric vehicle 100, as another example. In various other examples, the energy-absorbing impact assembly 800 can be located between the midpoint, the left-hand side, or the right-hand side of the front end 120 of the electric vehicle 100.

[0089] The tub 105 can include space positioned towards the rear end 125 of the electric vehicle 100 for the matrix material structure 810. For example, the energy-absorbing impact assembly 800 can be located on a left-hand side of the rear end 125 of the electric vehicle 100 (e.g., left-hand side of operator moving in a forward direction of travel). The energy-absorbing impact assembly 800 can be located on a right-hand side of the rear end 125 of the electric vehicle 100 (e.g., right-hand side of operator moving in a forward direction of travel), as another example. The energy-absorbing impact assembly 800 can be located at a midpoint (e.g., center) of the rear end 125 of the electric vehicle 100, as another example. In various other examples, the energy-absorbing impact assembly 800 can be located between the midpoint, the left-hand side, or the right-hand side of the rear end 125 of the electric vehicle 100.

[0090] The tub 105 can include space positioned on a side of the electric vehicle 100 for the matrix material structure 810. For example, the energy-absorbing impact assembly 800 can be located at various positions of a left-hand side of the electric vehicle 100 (e.g., left-hand side of operator moving in a forward direction of travel). The energy-absorbing impact assembly 800 can be located at various positions of a right-hand side of the electric vehicle 100 (e.g., righthand side of operator moving in a forward direction of travel), as another example. For example, the energy-absorbing impact assembly 800 can be located at any exterior position that surrounds the operator cabin 110 to absorb energy of impact.

The matrix material structure 810 can facilitate absorbing energy of impact of the electric vehicle 100 (e.g., a crash, collision, contact with an object). For example, the matrix material structure 810 can include a honeycomb material. The honeycomb material can be made from a mixture of filaments, elastomers, resins, or the like to provide elastomeric properties such that the matrix material structure 810 can dissipate energy (e.g., collapse, compress, or otherwise deform) in the event of a collision.

[0093] Generally, typical electric vehicles include one or more wire harnesses. For example, wire harnesses can include an assembly of electric cables, wires, or the like, which can transmit signals, electrical power, and/or current from one portion of the vehicle to another. Typical wire harnesses can cause additional manufacturing and packaging challenges and potentially lead to increased cabin noise (e.g., vibrations of cables) and additional weight added to the vehicle. Accordingly, it would be advantageous to provide a wire harness assembly that is formed directly with a portion of the electric vehicle 100 to address the aforementioned challenges.

For example, the wire harness assembly 1005 can be formed with one or more components of the composite structure 300 of the tub 105 through additive manufacturing (e.g., 3D printing). In various examples, at least a portion of the wire harness assembly 1005 can be formed with the composite structure 300 of the tub 105 such that the wire harness is integral (e.g., attached, fixed) with a portion of the tub 105. For example, the wire harness assembly 1005 can be formed with the tub 105 during the printing stage of 3D printing (e.g., during 3D printing of the shell 310), such that the wire harness assembly 1005 is integrally formed with the tub 105. A portion of the wire harness assembly 1005 (e.g., cables) can be formed with one or more components of the composite structure 300 of the tub 105 during additive manufacturing. Throughout the process of manufacturing, the portion of the wire harness assembly 1005 may be adjusted to conform to various shapes and configurations of the wire harness assembly 1005. For example, various cables of the wire harness assembly 1005 can be formed along the tub 105 via various extrusion processes of additive manufacturing including, but not limited to, quad extrusion. Various manufacturing systems, such as 3D printers, may include different extrusion heads each producing a different portion of the wire harness assembly 1005 (e.g., wiring, insulation).

The composite structure 300 can include various other materials formed with the shell 310 including epoxy, prepreg carbon fiber, and/or nomex honeycomb. For example, the materials can be stamped, welded, or pressed with the shell 310 to create the composite structure 300.

[0096] The method 1100 can include forming a portion of a wire harness assembly 1005 within the composite structure 300, as depicted in act 1110. For example, a portion of the wire harness assembly 1005 can be formed with one or more components of the composite structure 300 such that the wire harness assembly 1005 is integrally formed with a portion of the tub 105 (e.g., attached, fixed).

[0097] Generally, typical electric vehicles include one or more battery packs. For example, many electric vehicles include a battery pack that is separate from the vehicle and is integrated into a predetermined space post-manufacturing. Such configurations may lead to complex packaging challenges, limited spacing, and/or various other manufacturing challenges. Accordingly, it would be advantageous to provide a battery assembly that is formed directly with a portion of the electric vehicle 100 to address the aforementioned challenges.

[0098] FIG. 12 depicts a perspective view of a portion of the tub 105, according to an exemplary implementation. As shown in FIG. 12, the tub 105 can include a space for a battery pack assembly 1205 to be formed within the tub 105. For example, during additive manufacturing of one or more components of the composite structure 300 of the tub 105 (e.g., the shell 310, the first prepreg carbon-fiber layer 320, the second prepreg carbon-fiber layer 360), the battery pack assembly 1205 can be added to the composite structure 300 such that the battery pack assembly 1205 is embedded into a portion of the tub 105. By way of example, once the shell 310 is formed (e.g., via 3D printing), one or more prepreg carbon fiber layers (e.g., the second prepreg carbon-fiber layer 360) may be applied to the shell 310 surrounding the battery pack assembly 1205. The battery pack assembly 1205 and one or more carbon fiber layers can be formed (e.g., stamped, pressed, welded) together such that the battery pack assembly 1205 is integrally formed with the composite structure 300 of the tub 105. In various examples, the battery pack assembly 1205 can replace a component of the composite structure 300 of the tub 105. For example, the battery pack assembly 1205 can be formed with the composite structure 300 such that the battery pack assembly 1205 replaces a portion of the nomex honeycomb layer 340. The battery pack assembly 1205 can be formed with the composite structure 300 such that the battery pack assembly 1205 replaces a portion of various other components of the composite structure 300, as another example.

[0099] FIG. 13 depicts an example of the battery pack assembly 1205 formed within the tub 105. For example, the battery pack assembly 1205 can be or can include a stand-alone battery pack. The battery pack assembly 1205, or one or more components of the battery pack assembly 1205, can be made from carbon fiber. As shown in FIG. 13, the battery pack assembly 1205 can include a battery membrane 1320. For example, the battery membrane 1320 can include a material to facilitate separating the one or more battery cells 1335 within the battery pack assembly 1205 from one another. The battery membrane 1320 can be made from various materials including, but not limited to, polymers, resins, plastics, elastomers, and/or metals. The battery membrane 1320 can facilitate forming the battery cells 1335 with the composite structure 300 of the tub 105. For example, the battery pack assembly 1205 can include one or more carbon fiber layers 1315 surrounding the battery pack assembly 1205. The carbon fiber layers 1315 can be integrally formed with and/or be a part of one or more components of the composite structure 300.

[0100] The battery pack assembly 1205 can be embedded into the composite structure 300 of the tub 105 such that the battery pack assembly 1205 is not exposed to the exterior of the electric vehicle 100. For example, the battery pack assembly 1205 may be embedded in between the shell 310 and the second prepreg carbon-fiber layer 360 of the composite structure 300. The battery pack assembly 1205 may be embedded into the tub 105 such that the battery pack assembly 1205 is not exposed to environmental and exterior climate conditions such as fluid, dirt, or other debris. The battery pack assembly 1205 can allow for a more customizable battery pack solution (e.g., compared to conventional battery packs) with more efficient manufacturing and packaging.

[0101] As shown in FIG. 13, the battery pack assembly 1205 can include an anode 1340, a cathode 1330, and/or an electrolyte 1325. For example, the anode 1340 can include a negative electrode for releasing electrons within the battery cells 1335. The cathode 1330 can include a positive electrode that acquires electrons within the battery cells 1335. The electrolyte 1325 may be the medium that provides ion transport mechanisms between the cathode 1330 and the anode 1340 of the battery cells 1335. In various examples, the battery pack assembly 1205 may include various other components to facilitate providing electric power to the electric vehicle 100. While the exemplary implementation depicted in FIGS. 12 and 13 includes a battery pack assembly 1205 in one particular configuration, various other battery configurations may be includes in various other examples.

[0102] FIG. 14 depicts a method 1400 of providing a tub 105 for an electric vehicle 100. The method 1400 can include forming composite structure 300, as depicted in act 1405. For example, the composite structure 300 can include a 3D printed shell 310 made at least partially via additive manufacturing using carbon-fiber nylon filament and/or various other plastics. The composite structure 300 can include various other materials formed with the shell 310 including epoxy, prepreg carbon fiber, and/or nomex honeycomb. For example, the materials can be stamped, welded, or pressed with the shell 310 to create the composite structure 300.

[0103] The method 1400 can include forming a battery pack assembly 1205 within the composite structure 300, as depicted in act 1410. For example, the battery pack assembly 1205 can be formed with one or more components of the composite structure 300 such that the battery pack assembly 1205 is integrally formed with a portion of the tub 105 (e.g., fixed, embedded). For example, during additive manufacturing of one or more components of the composite structure 300 of the tub 105 (e.g., the shell 310, the first prepreg carbon-fiber layer 320, the second prepreg carbon-fiber layer 360), the battery pack assembly 1205 can be added to the composite structure 300 such that the battery pack assembly 1205 is embedded into a portion of the tub 105. By way of example, once the shell 310 is formed (e.g., via 3D printing), one or more prepreg carbon fiber layers (e.g., the second prepreg carbon-fiber layer 360) may be applied to the shell 310 surrounding the battery pack assembly 1205. The battery pack assembly 1205 and one or more carbon fiber layers can be formed (e.g., stamped, pressed, welded) together such that the battery pack assembly 1205 is integrally formed with the composite structure 300 of the tub 105.

[0104] Generally, carbon fiber has been used as a material for motorsport (e.g., racing) vehicles. However, due to lack of use in typical commercial vehicles and other mass produced vehicles, carbon fiber has rarely been tested for long-term usage. Accordingly, it would be advantageous to provide a means for predicting a physical state of carbon fiber within a vehicle over time.

[0106] The embedded sensors 1510 can include one or more components to detect a mechanical stress and/or strain value of the tub 105. For example, the sensors 1510 may include one or more strain gauges embedded with a portion of the carbon fiber material within the tub 105 (e.g., within the composite structure 300). The sensors 1510 can be or can include a temperature sensor, an accelerometer, a pressure sensor, or another type of sensor. The sensors can create the ability to improve the driving performance of the vehicle 100 by leveraging inputting sensor data into an active suspension system for an improved driver experience. The sensors 1510 may be able to detect strain at various locations of the tub 105. The sensors 1510 may communicably couple with a data processing system 1515. For example, the sensors 1510 may be able to send one or more signals to the data processing system 1515 to process the signals. In various examples, the data processing system 1515 may be internal to the vehicle 100. For example, the data processing system 1515 may be incorporated into a computing system for the electric vehicle 100. The data processing system 1515 may be incorporated or a component of an application-specific integrated circuit (ASIC) for the vehicle 100. In some examples, the data processing system 1515 may be external to and communicably coupled (e.g., via various application programming interfaces (APIs)) to the vehicle 100. The data processing system 1515 may be include various processors to calculate, based on the signals, a mechanical stress value of a location of the tub 105.

[0107] In various examples, the sensors 1510 may be embedded into the tub 105 such that the sensors 1510 are not exposed to the exterior of the tub 105 and/or the vehicle 100. For example, in some examples, the sensors 1510 may be formed with (printed into, molded, welded) the composite structure 300 of the tub 105 such that the sensor 1510 is not exposed to the environment surrounded the vehicle 100. In other examples, the sensors 1510 may be embedded into the tub 105 such that one or more portions of the sensors 1510 are exposed to the exterior of the tub 105 and/or the vehicle 100. For example, in some examples, the sensors 1510 may be formed with (printed into, molded, welded) the composite structure 300 of the tub 105 such that the sensor 1510 is exposed to the environment surrounded the vehicle 100. In various examples, the sensors 1510 may include one or more components to facilitate protecting the sensors 1510 from damage, such as a cover (e.g., cap, seal).

[0108] In various examples, the electric vehicle 100 may include several sensors 1510 positioned at various locations throughout the vehicle 100. For example, the electric vehicle 100 may include one sensor 1510. The electric vehicle 100 may include two sensors 1510, as another example.

[0111] Generally, in various types of vehicles, one or more LIDAR sensors or radars may be installed into a framework of the vehicle using subtractive manufacturing methods (e.g., machining). Furthermore, many typical LIDAR sensors may be attached to a top-side portion of a vehicle, creating aesthetic and aerodynamic challenges.
