Technical Field:

This invention relates to a coaxial aluminum sigma drone chassis that can be used in drones capable of carrying people or cargo.

State of the Art:

The chassis is the main support structure that carries all the other parts of the motor vehicle connected to it, such as the skeleton of an organism. Drones have a chassis that forms their skeleton. This chassis is a skeleton on which the drone and its parts are mounted.

The most common chassis types in current drones are X-type chassis and H-type chassis. These chassis types are usually made with carbon fiber, plastic or 3D printing. The most widely used is carbon fiber. Quality carbons are expensive. Chassis made of a mixture of carbon and other materials can also be at high prices according to the ratio of this mixture.

The patent application KR20210055263A describes the” Frame for Drone". The present invention relates to a frame for a drone, which comprises: a plurality of side frames having a main body coupled to a lower portion thereof and formed in a bent form to surround a portion of the side and upper surfaces of a fuel cell provided on an upper portion of the main body; an arm formed on an upper portion of the side frame and to which a rotor is coupled to an end thereof; and a fixed frame formed to connect upper ends of the side frames to each other. Accordingly, by distributing and supporting the load and pressure more efficiently, the stability of flight and the durability of the fuselage can be reinforced to prevent vibration caused by the rotation of the motor.

The above-mentioned patent application describes a chassis made of carbon on which the drone parts are mounted. Since no fastener is used in the fixing of the main body to the chassis, it does not have a solid structure. In addition, since the chassis is made of carbon material, the cost is high.

The patent application CN107618650A describes ”3D printed drone frame and drone". The invention discloses a 3D-printed drone frame and a drone. The drone frame comprises four regular-hexagon rotor protecting arms and a rectangular reinforcing frame and is characterized in that connecting plates are arranged among the regular-hexagon rotor protecting arms, the four regular-hexagon rotor protecting arms are integrally connected with the connecting plates, and the rectangular reinforcing frame is arranged below the regular-hexagon rotor protecting arms. The drone comprises the drone frame, a flight control system, a battery, a GPS positioning module, aerial photographing equipment and propellers. The 3D-printed drone frame and the drone have the advantages that the 3D-printed drone frame is fast formed and manufactured through a 3D printing process, process flow is reduced, and the drone frame and the drone are simple and stable in structure, reasonable in design and layout, convenient to mount and demount, reasonable in drone-carried electric equipment layout, stable in signal transmission, safe and reliable.

A drone frame made with 3D printing is described in the patent application mentioned above. Making the frame with 3D printing is costly and not a durable enough product. In addition, production time and assembly take time.

The patent application TR2021013913 includes an unmanned aerial vehicle. This invention relates to unmanned aerial vehicles that operate more efficiently by connecting to the plant on the ground or in a vehicle and supplying compressed air from the relevant plants. Fuel and energy savings are achieved by providing energy transfer to the unmanned aerial vehicles during their flight, by using compressed air conveyed on the lines, efficiency in the system as a result of the lightness of the material carried on the lines, and additionally using compressed air during the flight of the vehicles, and also by feeding the battery with compressed air. The chassis in the above-mentioned drone mechanism consists of a circular tube profile. Holes must be drilled on the surfaces of these circular pipe profiles for screwed/bolted installation of the chassis. Therefore, labor costs will increase, material losses and energy consumption will increase.

Consequently, there is a need for a new technology that is inexpensive, structurally sound, easy to assemble and disassemble, which can overcome the disadvantages mentioned above.

Description of the Invention:

This invention is a coaxial aluminum sigma drone chassis that can overcome the disadvantages mentioned above, and its feature is; It is light and cheap due to the aluminum sigma profiles, and it has a durable structure thanks to the strength of the fasteners used in the connection of the sigma profiles.

The product subject to the invention is a drone chassis that can be used to carry heavy loads or to carry people. The parts that make up the chassis are light, flexible, and durable, as well as being cheap and demountable, reducing the assembly cost of the chassis. In addition, it has a compact and modular structure that does not take up much space. The product of the invention is the Coaxial “H-type” drone chassis.

It is easy to install due to the easy fixing of the parts that make up the invention, and the costs are low due to the short assembly time and cheapness of the parts used. Moreover, the invention has a solid construction.

The parts constituting the invention are basically; sigma profile (1), hidden corner joint (2), wide corner joint (3) and bolt (4). Sigma profile (1) has sections of profile channel (1.1) and profile surface (1.2). The hidden comer joint (2) has guide holes (2.1) formed on its surfaces. There are ledges (2.2) on their side surfaces. The wide corner joint (3) has an L-shaped slot (3.1).

The invention consists of assembling sigma profiles (1) to each other. Sigma profiles (1) are connected to each other by hidden comer joint (2) and wide comer joint (3). Special bolts (4) are used during the assembly of the fasteners. The chassis is generally light, flexible, and durable, but also cheap and detachable.

Sigma profiles (1) are the basic part of the chassis of the drone. Sigma profiles (1) are made of aluminum material and there are profile channels (1.1) on which fasteners can be easily mounted.

The hidden comer joint (2) is L-shaped and connects the sigma profiles (1) with a right angle. The hidden corner joint (2) passes into the interior of the profile channels (1.1) and is prevented from coming out of the channels due to the ledges (2.2). It fixes the sigma profiles (1) positioned perpendicular to each other by nesting in the guided holes (2.1) with bolts (4). Hidden comer connection (2) is produced from zamak metal alloy and there is a screw hole (2.1) on both sides for metric bolt (4) to be attached. During the connection process, the hidden comer joints (2) is roughly hidden by being mounted inside the profile channels (1.1) on the sigma profiles (1).

The bolt (4) is used for the connection of the fasteners to the sigma profiles (1). Allen key is compatible and made of steel. It is manufactured to withstand extreme loads.

When the chassis assembly process is completed, it is ready for the placement of the electronic parts, the motor, wing, connection apparatus and the motherboard, processor, battery, etc. are attached to the profile ends. The drone installation process is completed by integrating the devices.
