DETAILED DESCRIPTION [00017] In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. One skilled in the relevant art will recognize, however, that the techniques described herein can be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring certain aspects.

[00018] Various features and embodiments of the present invention here will be discernible from the following further description thereof, set out hereunder. Further "front" and "rear", and "left" and "right" referred to in the ensuing description of the illustrated embodiment refer to front and rear, and left and right directions as seen from a rear portion of the vehicle and looking forward. Furthermore, a longitudinal axis Y - Y’ unless otherwise mentioned, refers to a front to rear axis relative to the vehicle, while a lateral axis X - X’ unless otherwise mentioned, refers generally to a side to side, or left to right axis relative to the vehicle.

[00019] However, it is contemplated that the disclosure in the present invention may be applied to any vehicle without defeating the spirit of the present subject matter. The detailed explanation of the constitution of parts other than the present invention which constitutes an essential part has been omitted at suitable places. [00020] Electrochemical cells including batteries are used as an electric source for an electric vehicle or a hybrid-powered vehicle is required to have high voltage and large capacity. The high-capacity battery adversely affects the storage space being configured to receive large articles in the vehicle. Further, the principal drawback of the existing batteries is the excessive time duration required to recharge a battery. To address the said issue, the battery swap system is known. However, batteries are heavy, and exchanging these batteries is a huge task as the battery is to be removed from the vehicle and charged in a battery charger or at a remote station. More specifically, the plurality of panels mounted to a frame assembly needs to be removed for accessing the battery that makes accessing the batteries cumbersome. Therefore, swapping the battery is time-consuming, as it is not readily accessible. Also, a dedicated locking provision is typically provided for securing the batteries in the vehicle which undesirably adds to the time and effort.

[00021] Further, in the battery, however, heat is developed not only by chemical reactions but also by Joule loss caused during charge and discharge cycles, increasing the temperature of the battery. The increase in temperature affects battery life and other battery properties. Therefore, various kinds of battery cooling systems are implemented to solve the above problem. However, a known cooling system comprises external cooling means which adds more weight and cost to the vehicle. Importantly, such systems are more viable for a four-wheeled vehicle owing to the feasibility of space & layout as well as the overall cost impact. However, for a straddle type two-wheeler or a three-wheeler (trike), there exists a challenge to design a compact, low weight, low cost, and efficient cooling system with good durability and reliability. [00022] At the same time, the automobile manufacturers need to cater to different market segments and users with product offerings and variants meeting the demands of respective users. These could involve variants in form of size, the capacity of the vehicle, range of usage, cost, ease of manufacturing, etc. From the manufacturer’s point of view, once a platform product is designed, the product economics would be viable based on the numbers sold. Therefore, it is always a challenge for an automobile manufacturer to have a vehicle layout and design which can be flexible to cater to the variants and the demands and enable modified versions with minimum changes in the vehicle layout, assembly time, manufacturing set-up, etc. The challenge is further complicated when the vehicle architecture/platform requirement needs to cater to different powertrains like the Internal combustion engine (ICE) to an Electric Powertrain or a Hybrid powertrain. Thus, the transition towards electric vehicles is a major challenge for the OEM’s (Original Equipment Manufacturer) in terms of manufacturing, as it requires revamping of core processes to prepare for mass production of the electric vehicles. [00023] Hence, there is a need for an improved storage assembly for a vehicle overcoming all the above problems as well as overcoming problems of the known art.

[00024] The invention is based on the object of making available an improved storage assembly for a straddle type vehicle which is of compact construction and is relatively simple, and which makes it possible to swap the batteries as and when required.

[00025] It is another object of the present invention is to provide a theft-proof, reliable, secure and efficient storage system being configured to maintain the optimum temperature of the electro chemical cells.

[00026] To this end, as per the first aspect, the frame assembly for a vehicle is disclosed which comprises of a pair of left and right rear tube. The pair of left and right rear tube being extending in a longitudinal direction of said vehicle from a portion of a main tube. A receiving chamber assembly being configured to be accommodated within said pair of left and right rear tubes of said frame assembly and said receiving chamber assembly extending in said longitudinal direction of said vehicle. The receiving chamber assembly being disposed below said seat assembly. Further, the receiving chamber assembly includes one or more receiving chamber. The one or more said receiving chamber is connected through a flexible mechanical linkage.

[00027] In accordance with this configuration and embodiment, the seat assembly covers the receiving chamber assembly Therefore, said receiving chamber assembly becomes accessible in an open condition of said seat assembly thereby providing antitheft arrangement without additional locking mechanism.

[00028] As per the second embodiment a frame assembly for a vehicle comprises a pair of left and right rear tubes; and a receiving chamber assembly, said receiving chamber assembly includes one or more receiving chamber, wherein one of said receiving chamber rests on an elastic member said elastic member is mounted on the frame assembly. The elastic member is mounted on a support plate, said support plate is attached to the frame assembly. Further, at least one of said pair of left and right rear tubes being configured to have one or more lock arm being configured to arrest the oscillating movement of said receiving chamber.

[00029] In accordance with this configuration, the elastic member is provided at the bottom of the receiving chamber. The elastic member aids the removal of the receiving chamber thereby providing convenience to the user.

[00030] As per further embodiment said receiving chamber being configured to have one or more attachment portion to secure receiving chamber to said frame assembly. The attachment portion is configured to have an arc-shaped profile. The arc-shaped profile being configured to have predetermined included angle ranging from 20 degrees to 180 degrees. The attachment portion of said receiving chamber is sandwiched between said rear tube and a seat bush of said seat assembly to provide reliable mounting.

[00031] In accordance with this configuration, one of the primary efficacies of the present invention is that the receiving chamber structure is optimized for weight and stiffness. The high weight of electrochemical cells tends to creates stress on the receiving chamber specifically on the attachment portions. Thus, the attachment portion is configured to have the arc-shape profile at a predetermined included angle which bears the weight of a plurality of electrochemical cells or large articles and other forces acting on it especially on unmetalled/rugged roads. Further, the load of the plurality of electrochemical cells or large articles is uniformly distributed which will not allow stress at the attachment portion of the receiving chamber exceeding the strength of the material.

[00032] As per further aspect, a portion of said receiving chamber assembly is covered by a pair of left and right side covers. The pair of left and right-side covers being configured to have vents. The receiving chamber being configured to have a plurality of fins.

[00033] In accordance with this configuration, one of the primary efficacies of the present invention is the improved durability of electrochemical cells because electrochemical cells operate at the desired temperature range due to cooling from the natural air which passes through the plurality of fins in the receiving chamber. More specifically, the receiving chamber is profiled to have the plurality of fins at a predetermined location, thus the incoming air can be easily guided through the receiving chambers without the use of any external suction means like blowing fan, etc. Further, the plurality of cooling fins on the outer casing allows more heat dissipation. High heat transfer from electrochemical cells is achieved as fins in the receiving chamber come in contact with incoming air at ambient temperature. [00034] In accordance with this configuration, one of the primary efficacies of the present invention is that the receiving chamber assembly is easy to install due to the absence of external means like a radiator, etc. which involves a plurality of pipes. Further, the radiator requires external power to run the cooling fan/blowers which will consume more energy and lead to the frequent discharge of the electrochemical cells.

[00035] As per further aspect, wherein said one or more receiving chamber being configured to accommodate one or more electrochemical cells. The electrochemical cell is removably mounted to one or more said receiving chamber.

[00036] In accordance with this configuration, one of the primary efficacies of the present invention is that the electrochemical cells are easily accessible after opening the seat assembly. [00037] As per further aspect, said at least one receiving chamber being configured to accommodate daily use objects including a tool kit, medical kit. [00038] In accordance with this configuration, one of the primary efficacies of the present invention is that the daily use objects are easily accessible after opening the seat assembly.

[00039] As per further embodiment said a tandem seat mounted on said pair of left and right rear tubes. The tandem seat includes a rider seat and a pillion seat, wherein an opening being provided between said rider seat and said pillion seat to access daily use objects including tool kit, medical kit.

[00040] In accordance with this configuration, one of the primary efficacies of the present invention is that the stored daily use articles are easily and quickly accessible through an opening provided between the rider seat and pillion seat. [00041] As per further embodiment wherein at least one of said plurality of receiving chamber being configured to have substantially greater storage volume than other receiving chambers.

[00042] In accordance with this configuration, one of the primary efficacies of the present invention is the flexibility to add more electrochemical cells to meet the customers’ expectations relative to performance, range, and reliability.

[00043] As per an embodiment, receiving chamber are stacked along the length direction of the vehicle such that the chambers are of decreasing order of height. [00044] In accordance with this configuration, this design enhances the flexibility for the user as well as the manufacturer to configure plurality of receiving chambers with varying capacity as well as avoid any compromise on the layout space in the rear wheel well which it is typically restricted by the suspension stroke movement during riding.

For sake of brevity, Figure la and Figure lb will be discussed together. As per illustrated embodiment, a straddle vehicle (100) (hereinafter “vehicle”) includes a frame assembly (101) to support different parts of said vehicle (100). The frame assembly (101) includes at least a main tube (102) extending rearwards from said head pipe (not shown), a pair of left and right rear tubes (103L,103R) extending rearwards from a portion of said main tube (102), a pair of side tubes (right side tube not shown, 104L) extending inclinedly downwardly and forwardly from said pair of rear tubes (103). Particularly, the frame assembly (101) forms the skeleton of the vehicle (100) and provides rigidity to the vehicle (100). More particularly, at least the pair of left and right rear tubes (103L, 103R) and the pair of left and right-side tubes (not shown, 104L) form a rear portion of the frame assembly (101) and contribute to rigidity thereof. A seat assembly (107) is disposed above a receiving chamber assembly (105). The seat assembly (107) includes a tandem seat mounted on said pair of left and right rear tubes (103L, 103R). The tandem seat includes a rider seat (107D) and a pillion seat (107B). As per alternative embodiment, the seat assembly includes a split seat including the rider seat (107D) and the pillion seat (107B) mounted on said pair of left and right rear tube (103L, 103R). In the present embodiment, an opening (107C) is provided between said rider seat (107D) and said pillion seat (107B) to access the receiving chamber assembly (105). The opening (107C) is provided with a cover (107E) wherein the cover (107E) is conforming to the contour of the seat assembly (107) on the exterior surface.

[00053] The receiving chamber assembly (105) is mounted on the frame assembly (101). As per the illustrated embodiment, the receiving chamber assembly (105) is mounted on the pair of left and right rear tubes (103L, 103R). A portion of the receiving chamber assembly (105) is surrounded by a pair of left and right tail covers (106L, 106R) on left and right side of the vehicle (100). The receiving chamber assembly (105) includes one or more receiving chambers (105A). As per an embodiment, the receiving chamber (105A) are stacked along the length direction of the vehicle (100) such that the receiving chambers (105A) are of decreasing order of height (H) e.g., HI, H2 etc. as seen in Fig lb. This design enhances the flexibility for the user as well as the manufacturer to configure plurality of receiving chambers (105A) with varying capacity as well as avoid any compromise on the layout space in the rear wheel well which it is typically restricted by the suspension stroke movement during riding. [00054] Figure 2a illustrates a perspective view of the vehicle (100) where few parts are omitted from the figure and an enlarged localized perspective view of a right-side cover (201R), as per embodiment, in accordance with one example of the present subject matter. Figure 2b illustrates the partial top view of the vehicle (100) as per embodiment, in accordance with one example of the present subject matter. For sake of brevity, Figure 2a and Figure 2b will be discussed together. A pair of side covers (201R, 201L) is configured to have a plurality of vents (202). As per the illustrated embodiment, the right-side cover (201R) is shown in figure 2(a). The side covers (201R, 201L) are disposed of in the lateral direction (X— X’) of the vehicle (100). As per the preferred embodiment, the side covers (201R, 201L) are detachably attached to the frame assembly (101) through one or more mounting lug (203). The incoming air is guided by a plurality of vents (202) in the side cover (201R) towards the receiving chamber assembly (105). The receiving chamber (105A) is configured to increase the amount of incoming air and to minimize the disturbance and reduction of airflow. This is accomplished through a plurality of fins (204) in the side surfaces of the receiving chamber (105A). The air passes through fins (204) provided on the side surfaces of the receiving chamber (105A), and heat is exchanged to the fresh air. More specifically, as per the illustrated embodiment, the incoming air is guided by a plurality of fins (204) over the receiving chamber (105A) towards a subsequent receiving chamber (105A) as shown by the arrows. Then, hot air (represented by arrow lines in Fig 2b) exists from the rear side of the vehicle through a gap (not shown) provided between the pair of said tail covers (106L, 106R) and a rear fender (205).

[00055] Figure 3 illustrates a partial perspective view and a localized enlarged view of the frame assembly (101) where few parts are omitted from the figure, as per embodiment, in accordance with one example of the present subject matter. Since there is a plurality of receiving chambers (105A) attached using flexible mechanical linkages (301), the reference would be made to only one of them for brevity. The flexible mechanical linkages (301) are provided on any one of the front and the rear surfaces of the receiving chamber (105A). As per the illustrated embodiment, the flexible mechanical linkage (301) includes hinges that connect the receiving chambers (105A) which as per an embodiment are four in number. Further, at least one of the receiving chambers (105A) is configured to receive electrochemical cells (302). The electrochemical cells (302) are configured to have a lid (303). The lid (303) being configured to have a handle (304) to pull out the electrochemical cells (302) from the receiving chamber (105A) for dismantling. Further, in one implementation, at least one of the receiving chambers (105A) is configured to receive daily use articles like a tool kit, medical kit. The receiving chamber (105A) is configured to have attachment portions (305). As per the illustrated embodiment, the attachment portions (305) are provided on the side surfaces of the receiving chamber (105A) such that it is extending in the longitudinal direction (Y-Y’) of the vehicle (100). The attachment portion (305) is configured to have an arcuate shape with a predetermined included angle (A). The predetermined included angle (A) as per an embodiment ranges from 20 degrees to 180 degrees.

[00056] Figure 4a illustrates a front side cut section view of the frame assembly (101) across the A-A’ plane as per embodiment, in accordance with one example of the present subject matter. Figure 4b illustrates a graphical representation depicting the difference of the section modulus between a conventional frame assembly and present frame assembly (101) as per embodiment, in accordance with one example of the present subject matter. Preferably, the vertical axis signifies the section modulus (mm ³ ). For sake of brevity, Figure 4a and Figure 4b will discussed together. The receiving chamber assembly (105) has a positive impact on the section modulus of the frame assembly (101) in the assembled condition. This improves the lateral stiffness of the frame assembly (101). More specifically, the sidewalls of the receiving chamber (105A) are formed with some load transferring features such as attachment portions (305) which increase the sectional modulus of the sidewall of the receiving chamber (105A) and prevent bending and/or buckling. The attachment portions (305) are preferable of an arc-shape in cross-section and are substantially continuous along the longitudinal length of the receiving chamber (105A). Preferably, the arc-shaped profile of attachment portions (305) is incorporated into side surfaces of the receiving chamber (105A) to limit the deflections. Further, the attachment portions (305) on the receiving chambers (105A) provide the rigidity required for supporting and transferring the load from the receiving chamber (105A) to a pair of left and right rear tubes (103L, 103R) in a mounted condition. For example, sidewalls of receiving chambers (105A) may otherwise be subject to buckling or crimping as a result of vertical loads. Further, the frame assembly (101) benefits from an increase in the section modulus to limit deflections as evident from the graphical representation as shown in figure 4b. The graphical representation shows column A and Column B. The height of column A represents the section modulus of a conventional frame assembly and the height of column B shows the increase in section modulus as a result configuring receiving chamber assembly (105) on the frame assembly (101) of the vehicle (100).

[00057] Figure 5 illustrates a rear side cut section view across B-B’ axis of the frame assembly (101) of the vehicle (100), and a localized enlarged view of the frame assembly (101) of the vehicle (100) as per embodiment, in accordance with one example of the present subject matter. The attachment portions (305) provided on both the sides of said receiving chamber (105A) is sandwiched between said rear tubes (103L, 103R) and a seat bush (107A) of said seat assembly (107) to provide reliable, stable and secure mounting. Once the seat has a payload in form of occupant, the weight is transferred from the seat to the seat bushes (107A) which in turn exert arresting force onto the attachment portion (305) thereby further enhancing the secure attachment of the receiving chamber (105 A) with the frame assembly (101). As per an embodiment, the seat bush (107A) is made of elastic material which further augments the stability by absorbing any undesirable vibrations, achieve vibration resistance and dampen any micro deformations of the attachment portions (305).

[00058] Figure 6a illustrates a front side perspective view and rear side perspective view of the frame assembly (101) of the vehicle (100) as per alternative embodiment where few parts are omitted from the figure as per embodiment, in accordance with one example of the present subject matter. Figure 6b illustrates an exploded view of the frame assembly (101) as per alternative embodiment, where few parts are omitted from the figure as per embodiment, in accordance with one example of the present subject matter. For sake of brevity, Figure 6a and Figure 6b will be discussed together. As per the illustrated embodiment, the bottom portion of the receiving chamber (105A) rests on a preloaded elastic member e.g., elastic member (601). The elastic member (601) is mounted on the frame assembly (101). As per the illustrated embodiment, the elastic member (601) is mounted on a support plate (602). The support plate (602) is welded to the frame assembly (101). Further, one or more lock arm (603) to secure the receiving chamber (105 A) is configured on at least one of said rear tubes (103L, 103R) of the frame assembly (101), to arrest the oscillating movement of the receiving chamber (105A). As per illustrated embodiment, the lock arm (603) is provided on the right-side rear tube (103R) of the frame assembly (101).

[00059] According to the above architecture, one of the primary efficacies of the present invention is that the receiving chamber assembly is implementable without any major change in an existing frame assembly, to convert existing fossil fuel-based vehicles with automatic or manual transmission into an electric vehicle/ hybrid electric vehicle.

[00060] According to the above architecture, one of the primary efficacies of the present invention is that the receiving chamber assembly can be coupled to the platform of a new vehicle for different market segments by OEM’s because the present invention provides flexibility to manufacture variants in form of size, the capacity of the vehicle, range of usage, cost, ease of manufacturing, etc. The design of receiving chamber assembly is flexible to cater to the variants and the demands and enable modified versions with minimum changes in the vehicle layout, assembly time, manufacturing set-up, etc. and does not require a major revamping of core processes to prepare for mass production of electric vehicles during the transition from internal combustion engines.

[00061] According to the above architecture, one of the primary efficacies of the present invention is that the receiving chamber assembly provides flexibility to the customer to restore the original state i.e., from an electric vehicle to IC powered vehicle with fewer efforts due to less weight and simple design. The user can restore the vehicle to IC powered vehicle just by removing the receiving chamber assembly without the use of specialized tools and do away with the excess weight while at same time leverage the space as a secure storage space to store items. [00062] While the present invention has been shown and described with reference to the foregoing preferred embodiments, it will be apparent to those skilled in the art that changes in form, connection, and detail may be made therein without departing from the spirit and scope of the invention.
