Bumper-small longitudinal beams integrated structure of off-road vehicle

Abstract

The invention discloses a bumper-small longitudinal beams integrated structure of an off-road vehicle. The structure comprises a front bumper body, and each of the left side and the right side of theback face of the front bumper body are fixedly provided with a small longitudinal beam for being fixed to a vehicle body longitudinal beam. The front bumper body is provided with a winch support installation structure for installing a winch support, a towing ring installation structure for installing a towing ring of a trailer and a protection plate installation structure for installing a cabin lower protection plate. A vehicle body suspension support for being connected with a vehicle body and a radiator assembly installation support for installing a radiator assembly are fixed to each smalllongitudinal beam. On the basis of the front bumper body, the small longitudinal beams connected with the longitudinal beam are integrated; the installation points of the winch support and the trailertowing ring are arranged on the front bumper body; when the winch, the towing ring or the radiator assembly needs to be disassembled, assembled or maintained, only the installation connector, on thebumper or the support, of the winch, the towing ring or the radiator assembly needs to be disassembled.

Description

technical field [0001] The invention relates to the technical field of body parts, in particular to an integrated structure of an off-road vehicle bumper and a small longitudinal beam. Background technique [0002] Off-road vehicles often drive in the field, and the road conditions are poor. In order to ensure that the vehicle will not break down accidentally, devices such as winches and trailer traction rings are usually installed on the front bumper to rescue and rescue other vehicles. The connection strength puts forward higher requirements. The front bumper of an off-road vehicle not only needs to absorb and moderate the external impact, but also bears a lot of pull force from the winch and the traction ring of the trailer, so it generally needs to be equipped with a thick and strong front bumper. The strong structural force needs to be transmitted from the bumper to the frame rail, but the bumper is a distributed installation structure. Such an installation structure h...

AI Technical Summary

Problems solved by technology

The strong structural force needs to be transmitted from the bumper to the frame rail, but the bumper is a distributed installation structure. Such an installation structure has problems such as large space occupation, difficult assembly, poor maintainability and complex structure. It not only compresses the engine compartment space, and the reliability of the installation connection strength is difficult to guarantee
