DESC:FIELD OF INVENTION
[0001] The present invention relates to a vehicle. More particularly, the present invention relates to a bumper assembly for the vehicle.
BACKGROUND
[0002] In many of the developing & under developed countries, a motor vehicle particularly a three-wheeled automotive vehicle is a significant mode of public transportation. It is vastly used as a point to point mode of transport of both goods and persons from one place to other in rural as well as in urban areas. The three-wheeled vehicle is generally characterized by a tin, iron or sheet metal body resting on a front wheel and a pair of rear wheels and includes a cabin constituting a passenger compartment. While negotiating traffic condition, a rear end collision can result in damage to the cabin thus resulting in the replacement of whole cabin which can be complex as well as costly.
[0003] With the proliferation of governmental standards on safety standards and regulations in terms of safety performance requirements for motor vehicles, a wide variety of energy absorbing bumper assemblies have been installed on vehicles. Bumpers are metal shields designed to absorb shock caused due to impact and collision and hence prevents or reduces damage to the vehicle. Generally, a bumper attached or integrated to the front and rear of the vehicle absorbs impact in a minor collision and prevents the vehicle body from damage and hence minimizing the repair costs. Thus, with a front or rear impact at a relatively low speed against other vehicles or else against fixed obstacles, the bumper has the purpose of absorbing energy by undergoing deformation to prevent damage to other components.
[0004] In a known arrangement of the bumper assembly in a vehicle, the bumper is provided for a front end or rear end of a motor vehicle. For a front end of the motor vehicle, the bumper system typically includes a bumper beam extending transversely and secured to a forward end of a pair of front rails, which extend longitudinally and are spaced transversely.
[0005] In a conventional three-wheeled vehicle, the bumper relates to a rear body structure and is mounted to the cabin. However, the cabin being made up of sheet metal and the bumper that of a strip of steel is not strong enough to withstand impact. Thus, if the rear structure of the vehicle is damaged by any collision or impact, then the damage is caused to both cabin and the bumper and hence the repairing involves the replacement of both bumper and the cabin.
[0006] In another known arrangement of the bumper assembly to the three-wheeled vehicle, the rearward mounting of the bumper to the cabin leads to the immediate breakage of the cabin and the bumper even at light collision, thereby necessitating replacement with a new cabin, which is expensive and leads to an increase in repair cost.
[0007] The conventional arrangement and mounting of the bumper on the rear body structure that is the cabin of the three-wheeled structure has been a weak installation and hence the cabin gets scraped, scratched and dented from a minor collision. Hence, resulting in the replacement of both bumper and cabin which is generally complex and prohibitively costly. Thus, there is a continuing need for an improved mounting provision for the bumper assembly to the vehicle which is simple, light weight, damage resistant and which can be assembled independent of cabin at a reasonably low cost.

DETAILED DESCRIPTION
[00015] Automotive industries have recognized the need for lightweight, fuel efficient automobiles with safety standards and regulations imposed by the government. One such automotive component subject to heavy regulation is bumper assemblies with regard to crash safety standards. Bumper assembly installed on the vehicles serves to protect the vehicle in low-speed impacts.
[00016] Conventionally, the bumper assembly is comprised of a bumper beam made of a metallic material with the requisite strength to conform to governmental standards for low and high speed crashes. However, in a three-wheeled vehicle, the bumper assembly is mounted only to a rear structure of the vehicle. Since both cabin and bumper are made up of sheet metal, hence are not strong to withstand the damage due to minor collision. In the three-wheeled vehicle, the bumper is welded to the cabin such that any collision or impact to the rear of the vehicle can result in damage to both cabin and the bumper. Thus, replacement of said cabin and said bumper is costly. Though bumper is available at lower cost, but the replacement of the cabin is expensive thus increasing overall repairing cost.
[00017] The disadvantages of the conventional mounting of the bumper to the cabin of the three-wheeled vehicle can be overcome by mounting the bumper to the vehicle chassis. Thus, providing easy serviceability and minimizing the overall repairing cost.
[00018] With the above objectives in view, the present invention discloses the bumper assembly for the three-wheeled vehicle mounted on the vehicle chassis in the manner that the bumper is assembled independent of the cabin and hence any damage to the bumper due to any collision results in replacement of only bumper and not the cabin.
[00019] With one embodiment of the present invention, the bumper assembly is mounted to the chassis of the vehicle and any impact to the bumper results in replacement of bumper and hence minimizing the repairing cost and providing requisite strength to the vehicle body. Thus, the improved mounting of bumper assembly to the vehicle chassis is strong enough to provide excellent performance in high speed and low speed crashes.
[00020] The present invention relates to a rear body structure for the vehicle. More particularly, the present invention relates to the bumper assembly mounted to the chassis in the rear of the vehicle along the traverse axis of the vehicle. Thus, any minor collision to the rear structure of the vehicle results in the damage to the bumper. The bumper replacement is done at low cost. The bumper assembly is mounted in the manner that the opposing ends of the bumper of the bumper assembly is curved thus preventing the side impact to the vehicle.
[00021] As per one embodiment of the present invention, the vehicle chassis comprises a front portion, a rear portion and a pair of side rails extending longitudinally from said front portion to said rear portion. In one embodiment, the bumper assembly is detachably mounted to the rear portion of the chassis of the three-wheeled vehicle. The front portion of the chassis comprises of a floor panel rigidly secured to at least some portion of said pair of side rails. The rear portion of the chassis defines said pair of side rails extending upwardly from the opposite sides of said front portion of said pair of side rails and further terminating rearwardly along the longitudinal axis of said vehicle. As per one embodiment, the bumper assembly includes the bumper extending along the transverse axis of the vehicle. The bumper assembly is detachably mounted to said pair of side rails through at least one mounting member. Thus, the bumper assembly is assembled independent of the cabin of the three-wheeled vehicle. Hence, any damage to the vehicle due to collision or impact protects the cabin from damage.
[00022] The present invention discloses the bumper assembly being detachably mounted to said pair of side rails of the rear portion of the vehicle chassis through said at least one mounting member. As per one embodiment of the present invention, said at least one mounting sub-assembly comprises of at least one mounting bracket and at least one mounting contact portion for assembling said bumper assembly to the chassis. As per one embodiment, said a least one mounting bracket is an inverted J-shaped bracket. As per one embodiment of the present invention, said inverted J-shaped mounting bracket comprises an angle of bent ranging from 30° to 90°.
[00023] Preferably, the rear portion of the vehicle chassis comprises said pair of side rails extending upwardly from opposite sides of the front portion of the chassis and further extending rearwardly along the longitudinal axis of the vehicle. Thus, the bumper assembly mounted to the rear portion of the vehicle chassis undergoes deformation to prevent damage to one or more components including the cabin of the vehicle by absorbing the rear impact to the vehicle body.
[00024] As per one embodiment of the present invention, the rear portion of the vehicle chassis provided with the bumper assembly comprises of said bumper extending along the transverse axis of said vehicle and said at least one mounting member. The bumper is detachably mounted to said pair of side rails of said rear portion of said chassis through said atleast one mounting member. The bumper assembly mounted to the rear portion of the chassis and assembled independent of the cabin protects the cabin from damage and break from any impact by collision.
[00025] It is advantageous to have the bumper assembly assembled separately on the vehicle chassis. Such mounting of the bumper assembly to the vehicle chassis protects the cabin of the three-wheeled vehicle from being damaged thus minimizes the repairing cost. Also, as per one embodiment of the present invention, the bumper has a arcuate surface with different radii such that the opposing ends of the bumper is curved and thus protecting the vehicle from side impact, scratches and dent. As per the present invention, the mounting of the bumper assembly to the vehicle chassis contribute rigidity to the vehicle body and hence prevents from damage or dent by absorbing the rear impact.
[00026] Although the present invention has been exemplified for the three-wheeled vehicle, it is not restricted only for the three-wheeled vehicle. Application of the present invention may be extended to other vehicles, including four –wheeled vehicles.
