FIELD OF THE INVENTION The present invention generally relates to vehicle structure and more particularly relates to a modular frame structure for the vehicle.

BACKGROUND OF THE INVENTION Generally, frame structures of vehicles have been often seen to be custom designed with a number of components constructed in different shapes. Conventionally manufactured frame structures involve these components, made with MS pipes, are welded together in a single frame fixture in accordance to the desired design and specification of the vehicle which, so far, has been the most cost efficient technique.

However, the welding of different components of the frame structure, though a conventional technique, suffers several disadvantages. The welding process produces huge amount of heat which leads to expansion and distortion of the components of the frame being welded. Another disadvantage of welded frame structures is that in case of an accident/crash of a vehicle, if a minuscule component gets deformed or destroyed, the whole body frame has to be replaced to ensure that the strength and safety of the vehicle is not compromised with.

Further, bolted structures used in vehicle have been known in manufacture of trellis frames with bolts on the engine and swing arm together, particularly in high end performance bikes. However, the welded pipe structure still decides to a huge extent the strength of the vehicle. Therefore, there is a need to manufacture a chassis and/or a body frame structure which has replaceable components without having to compromise on the strength, sturdiness and performance of the vehicle.

Accordingly, there exists need in the art to provide solution to overcome the problems, but not limited to, aforementioned drawbacks/shortcomings associated with the existing frame structures for automatives.

The information disclosed in this section is only for enhancement of understanding of the general background of the invention. The approaches described herein are approaches that could be pursued, but not necessarily approaches that have been previously conceived or pursued. Therefore, unless otherwise indicated, it should not be assumed that any of the approaches described in this section qualify as prior art merely by virtue of their inclusion in this section nor should they be taken as an acknowledgement or any form of suggestion that this information is already known to a person skilled in the art.

In the following description, for the purposes of explanation, various specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that the disclosed embodiments may be practiced without these specific details. Several features described hereafter can each be used independently of one another or with any combination of other features. However, any individual feature may not address any of the problems discussed above or might address only some of the problems discussed above in the background section. Some of the problems discussed above might not be fully addressed by any of the features described herein. Although headings are provided, information related to a particular heading, but not found in the section having that heading, may also be found elsewhere in the specification. Further, information provided under a particular heading may not necessarily be a part of only the section having that heading.

In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, that the present invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in line diagram form in order to avoid unnecessarily obscuring the present invention. The invention encompasses a modular arrangement of the body frame structure/ chassis of a vehicle. The chassis components are bolted together and may be detached and replaced, as and when required. The frame/chassis encompassed herein is sturdy and efficient with no compromise on the accuracy or performance of the vehicle. As used herein, a 'vehicle' refers to a mobile machine that transports people or cargo. The vehicle may include, but are not limited to, an electric vehicle, a hybrid vehicle, a conventional vehicle, an alternative fuel vehicle, and any other vehicle having at least a wheel which may be obvious to a person skilled in the art.

As illustrated in FIG.l, the present invention relates to a modular frame, wherein the modular frame has a modular arrangement of the body frame structure/ chassis of a vehicle is provided which comprises of, but not limited to, a steering frame [1] for accommodating a steering assembly; a modular mount assembly [6] for accommodating a rear frame and at least one channel [5] for connecting the steering frame [1] to the rear frame of the modular mount assembly and combination thereof.

The steering frame [1] of the vehicle accommodates a front wheel and a steering assembly. The steering frame [1] further comprises a steering sleeve [la] joined and/or detachably coupled to at least one of a first frontal member [lb] or a second frontal member [lc]. The at least first frontal member [lb] or a second frontal member [lc] comprises of a mounting member that facilitates the mounting of at the least first frontal structure [lb] or second frontal structure [lc] to the at least one channels [5]. The steering assembly as used herein may comprise of a front wheel, a fork, a bracket, a steering column, a suspension system, a brake, a front vehicle mount and combination thereof.

Further, embodiments of the present invention encompasses the at least one channel [5] being connected to the at least one first and/or second frontal structure at one end [5a]. The present invention also encompasses the at least one channel [5] being connected to the one rear frame having a lower frame [4], a upper frame [3] and combination thereof. Moreover, the upper frame [3] is provided to support at least one seating arrangement whereas the lower frame [4] is provided to support a rear wheel. The at least one channel [5] extending rearwards has a vertical member to accommodate a stepped up footboard.

Further, with reference to the FIG.l of the present invention, the lower frame [4] may be detachably mounted on the modular mount assembly [6]. In this particular embodiment, the lower frame [4] extends rearwards towards the modular mount assembly [6] such that a rearward extended member [4a] further extends laterally and horizontally supporting an axle [7]. In one embodiment of the present invention, the modular mount assembly [6] of the present invention is configured to adapt a motor/prime mover. In another embodiment of the present invention, the upper frame [3] may be detachably coupled/mounted on the modular mount assembly [6] and the lower frame [4]. Further, in an alternative embodiment, a bushing member may be placed between one of the at least one channel [5], the steering frame [1], modular mount assembly [6], the upper frame [3], the lower frame [4] and combination thereof. Further, with respect to the present invention, the upper frame [3] and the lower frame [4] may be connected using a vertical rod and may be detachably coupled/mounted on modular mount assembly [6].

The modular mount assembly [6] houses a motor at an one end and the axle [7] at an another end. Further, in accordance with the present invention, the at least one channel [5] is connected to the modular mount assembly [6] through the axle [7].

Furthermore, the connection/coupling between the steering frame [1], the modular mount assembly [6], the at least one channel [5] and any combination thereof may be arranged in a detachable manner for providing modularity to the structure.

The mounts and components that characterize the invention, as illustrated hereinabove, are bolted to each other, either partially or fully, depending upon the design, structure and strength desired. In an embodiment where the bolts are partially used, the remaining components are typically welded employing conventionally known techniques. Alternatively, in yet another embodiment all the components of the chassis are bolted.
