FIELD OF INVENTION:
[001] The present invention relates to the field of vehicle. The present invention in particular relates to an integral rear bumper with tool box, rear lamps and step.
DESCRIPTION OF THE RELATED ART:
[002] One of the ways in which automobile and truck manufacturers are attempting to improve the average fuel efficiency of the vehicles is by reducing the weight of the vehicle components. Reduction of vehicle weight permits smaller, more fuel efficient engines to be used to power the vehicle. One area under study has been the bumpers which conventionally are made of heavy guage steel. It has been proposed that the bumpers be fabricated of aluminum or plastic material, both of which permit a weight and cost saving over the types of steel conventionally used in bumper fabrication. Bumpers made of aluminum or plastic, however, present fabrication difficulties, and also have met consumer resistance as being of questionable durability and damageability.
[003] Rear bumpers for light trucks and van-type vehicles, in particular, present even greater fabrication difficulties than the ordinary bumper since it is desirable that a step portion be incorporated in the bumper structure to facilitate ingress and egress to the cargo area of the truck or van.
[004] Reference may be made to the following:
[005] Patent No. US3614136 relates to a combined bumper and tool box is provided having a rigid tray which is completely open at the top. A three section hinged cover for the tray is provided comprising a central section and two side sections. The closed central section covers projections on the side sections so that locking the central section closed can lock all three sections closed. The cover sections have inter-engaging parts through which all three sections may be detained in open positions.
[006] Publication No. US4266817A relates to a dual-step rear bumper assembly for a truck. The bumper assembly comprises a main or lower crossmember 15 extending the full width of the truck. The crossmember provides the principal bumper strength and also the lower step (16 or 17) of a dual-step feature. To this crossmember 15 is attached an upper crossmember 28 having tread portions providing the upper step 29 or 31 of the dual-step feature. The bumper assembly ends are capped by end bulkheads 41 and 44. Intermediate bulkheads 42 and 43 box in the ends of the license plate cavity located at the center of the bumper assembly. The bulkheads may be of a much lighter gauge metal then the bumper cross members. The bulkheads provide the necessary vertical compression load resistance to support the weight of a person stepping on the upper step portions.
[007] Publication No. CN217384055 relates to an automobile bumper small logo installation deviation measuring tool, comprising an automobile bumper body and an installation assembly, one side of the automobile bumper body is provided with a fixing ring, one side of the fixing ring far away from the automobile bumper body is provided with an installation groove used for placing an automobile logo, and the fixing ring is buckled with the installation assembly; the mounting assembly comprises a clamping piece, limiting pieces, a piston rod, box bodies, a measuring scale and a limiting column, the clamping piece is of an annular structure, the clamping piece is arranged on the fixing ring in a sleeving mode, the two ends of the clamping piece are fixedly connected with the box bodies, the two box bodies are oppositely arranged, the limiting pieces are arranged in the clamping piece, the two limiting pieces are oppositely arranged, and the piston rod is arranged on the piston rod. The limiting piece is located in the mounting groove and connected with the box body through a piston rod. Through the design of the mounting assembly, the vehicle logo can be conveniently mounted, left-right deviation of the vehicle logo is avoided, the moving distance of the limiting piece can be controlled through a measuring scale, and the precision of the vehicle logo during mounting can be improved.
