DETAILED DESCRIPTION

[00017] Generally, in a two-wheeled vehicle with a mono-tube frame assembly, a single tubular structure extends rearwardly from the head tube towards a floorboard defining a step-through portion of the vehicle. Further, various vehicle components that include the power unit, a fuel tank, and a seat assembly are mounted to the frame assembly. Generally, such a vehicle has a naked appearance as it is conventionally called. In such vehicles, majority of the vehicle components are exposed to the atmosphere.

[00018] Especially, in vehicles with power unit including the engine assembly, the engine assembly includes a starter system. Vehicles, now a days, are provided with electric start mechanisms for providing ease of starting. Also, vehicles are loaded with safety systems including an integrated starter generator and/or an anti-lock braking system. The aforementioned systems are operated using the auxiliary power source and one or more control units. Therefore, the auxiliary power source and the control unit are crucial for functioning of the vehicle.

[00019] Often compact vehicle packaging and layout leads to shortage of space to package the auxiliary components of the vehicle like the battery, mobile charging unit, controller etc. Also many of such auxiliary components can be heavy and thus dis-proportionate disposition of such components across the vehicle layout can lead to poor mass centralization and affects the centre of gravity of the vehicle. This may cause riding discomfort and poor handling of the vehicle. Also, accessing of such auxiliary components for service becomes cumbersome owing to need to open body panels, other vehicle system and requires more time if these are disposed across different locations on the vehicle.

[00020] Components such as battery, mobile charge, and controller need to be adequately protected from mud, water, or other environmental factors to achieve good durability of the parts and longevity of the vehicle as a whole.

[00021] In case of vehicle employed with Integrated starter generator (ISG) or vehicles with electric traction motor, it becomes important to be able to provide adequate storage space for components like battery or controller that work with the ISG or electric traction motor and such heavy parts are to be disposed safely, and securely as well as providing ease of access for swapping, replacement/ repair or charging.

[00022] Parts like controller, canister or air filter also need to be placed in vicinity of the power train system to minimize wiring, cabling & connections required for the parts to functionally interface with each other.

[00023] In addition, to securely locate the aforementioned systems/components, the vehicle is to be provided with a storage space that is also used by the user for storing essential documents or tools. Moreover, such storage space is also to be secured from theft or the like.

[00024] Therefore, there is a need for securely mounting such components including the auxiliary power source and the control unit(s). The components are to be accessible by only an authorized user. Also, the storage space provided is also to be accessible by authorized user. At the same time, the compact layout of the naked type of vehicle is to be retained.

A first line B-BD passing parallel to the long axis of the base member 205B is at a first angle with a second line S-SD passing along the long axis of the support member 205S. The first angle is an acute angle in the range of 25-75 degrees. The first angle in the specified range enables the auxiliary storage unit 200 to have a compact layout thereby enabling compact assembly. Also, the first angle is chosen to be preferably matching with the inclination of the rear tube 105D. The first line B-BD is considered as the long axis B-BD of the base member 205B. Also, the support member 205S is provided with at least one step-portion disposed at a lateral off-set from a longitudinal axis F-R of the vehicle 100 in order to accommodate at least one electrical component deposed thereof.

Furthermore, the first step portion 205SF and the second step portion 205SS extend adjacently of the rear tubes 105D. The step portions 205SF, 205SS of the support member 205S is provided with one or more ribs 205RR that are disposed vertically connecting the bottom portion of the support member 205S to the base member 205B thereby providing structural strength to the support member 205S to support the electrical components 170, 175. The first step portion 205SF and the second step portion 205SS define a shell with at least one opening for receiving the electrical components 170, 175, wherein in the present implementation the shell is having an upward and a forward opening to receive the electrical components 170, 175. Further, the shell is adapted to have a cross-section complementing shape of the electrical components 170, 175. In other words, in a side view, the rear tubes 105D of the frame assembly 105 overlaps with at least a portion of the first step portion 205SF and the second step portion 205SS. This provides a compact layout for mounting the battery 170 and the control unit 175.

[00062] Fig. 2 (e) depicts a right side perspective view of a portion of the auxiliary storage unit 200 and cross-sectional view taken along X-XD thereof. Fig. 2 (f) depicts another perspective view of a portion of the auxiliary storage unit 200 employed with a controller case 175C and a battery 170.

[00063] Further, in an embodiment, the auxiliary storage unit 200 is provided with a controller-casing 175C for accommodating the control unit 175. The controller-casing 175C is preferably made of non-conducting material to isolate the control unit 175 from electrical shorts. Moreover, the controller-casing 175C is provided with plurality of fins or heat sinks to enable heat dissipation from the control unit 175. The controller-casing 175C is affixed to the support member 205S at the first step portion 205SF. The battery 170 is mounted to the second step portion 205SS and in a detachable manner. The battery 170 is secured to the base member 205B using an elastic strap or the like.

[00064] Fig. 3 (a) depicts a cross-sectional view of the auxiliary storage unit employed in the vehicle, in accordance with the embodiment depicted in Fig. l. The cross-section is taken along a horizontal plane with respect to the vehicle 100. The auxiliary storage unit 200 securely encloses the battery 170 and the control unit 175. In the top view, the control unit 175, the battery 170, and the rear tube 105D are adjacently disposed. Further, the battery 170 and the control unit 175 are disposed substantially parallel to the longitudinal axis F-R of the vehicle 100. The longitudinal axis F-R is considered to be substantially at a lateral center of the vehicle 100. However, in another embodiment, at least one of the battery 170 and the control unit 175 are inclinedly disposed with respect to the longitudinal axis F-R of the vehicle 100 to accommodate length of the electrical components.

[00065] Fig. 3 (b) depicts a top view of the auxiliary storage unit employed with the frame assembly 105. In the top view, the width of the auxiliary storage unit Wl is substantially lesser than the width of the seat assembly 160 (shown in Fig. 1), which includes the rider seat 160A and the pillion seat 160B. Also, in one embodiment, gap between the inward facing sides of the foot rests 180 is represented as W3, which is greater than the width of the auxiliary storage unit Wl. Especially, the width of the auxiliary storage unit Wl is lesser than the width of the seat assembly W3, thereby keeping the vehicle layout compact. Therefore, the width of the auxiliary storage unit Wl is within the width of the vehicle 100 thereby retaining the compact layout of naked type vehicles.

[00066] Fig. 4 (a) depicts a front perspective view of an auxiliary storage unit, in accordance with another embodiment of the present subject matter. Fig. 4 (b) depicts another view with parts exploded, in accordance with the embodiment of Fig. 4 (a). The said auxiliary storage unit 200 includes the casing 205 formed by the base member 205B, a right wall member 205R, and a left wall member 205L. The right wall member 205R, and the left wall member 205L are laterally disposed. The base member 205B is disposed rearward/downward and at least one of the primary cover member 215 (shown in Fig. 4 (b)) or the secondary cover member 215 securely close the casing from upward/front portion.

[00067] In the present embodiment, an alternate power source 171, which is different from the auxiliary storage unit 170 (shown in Fig. 2 (b), is securely disposed in the auxiliary storage unit 200. For example, the alternate power source 171 is a Li-ion battery that is maintenance free compared to Lead-acid battery. However, the Li-ion battery conventionally available is having width substantially greater than a Lead-acid battery. However, the present subject matter enables storage of said alternate power source 171 with ease.

[00068] In one implementation, the alternate power source 171 is having a length around 115 millimeters, a height around 86 millimeters, and a width around 70 millimeters. The auxiliary storage unit 200 is capable of accommodating the power source 170 or 171 with a first side disposed along the lateral direction RH-LH and a second side disposed along the longitudinal direction having a ratio in the range of 0.45 to 1.65. Thus, the present subject matter enables accommodation of auxiliary power sources with varying dimensions at the same time accommodating other electrical components like controllers compactly.

[00069] The auxiliary storage unit 200 includes a support member 205S mounted to the base member 205B . The support member 205S includes at least one stepped portion 205SF, 205SS (similar to support member shown in Fig. 2 (b)) disposed at a lateral off-set from the longitudinal axis F-R of the vehicle 100. Further, an intermediate portion 205SI is extending orthogonal to the at least one stepped portion 205SF, 205SS, which is lateral direction. The alternate power source 171 is disposed at the intermediate portion 205SI, wherein a long axis C-CD of the alternate power source 171 is orthogonal to the longitudinal axis F-R of the vehicle 100. It is an advantage that the present subject matter enables mounting a Lead-acid battery or a Li-ion battery depending on user requirements with same ease and security.

[00070] Further, at least one electrical component is the controller 175 disposed at lateral offset from the lateral center of the vehicle 100. The auxiliary storage unit 200 further enables storage of another electrical component, which is the alternate power source 171 disposed in another first orientation with respect to the controller 175. Therefore, the battery 170 is disposed perpendicular to the control unit 175, wherein the first orientation is perpendicular to the controller.

[00071] Thus, in the current embodiment, the control unit 175 is disposed on the first step-portion 205SF and the alternate power source 171 is disposed orthogonal to the longitudinal axis F-R. Further, the alternate power source (171) is secured to the base member 205 through a securing member 171S having at least two arms. At least one arm of the at least two arms abuts the auxiliary power unit 171 and the securing member 17 IS is secured to the base member 205B through at least one other arm of the at least two arms. Thus, the securing member 171 S restricts movement of the alternate auxiliary power source 171 thereby enabling secure mounting thereof.

[00072] It is to be understood that the aspects of the embodiments are not necessarily limited to the features described herein. Many modifications and variations of the present subject matter are possible in the light of above disclosure. Therefore, within the scope of claims of the present subject matter, the present disclosure may be practiced other than as specifically described.
