Description

Technical Field

[0001] This utility model belongs to the field of rear anti-collision tube beam technology, specifically, it relates to an anti-collision tube beam for the rear bumper of an off-road vehicle. Background Technology

[0002] Off-road vehicles are typically equipped with rear bumper beams to protect against rear-end collisions. These beams consist of crossbeams and energy-absorbing boxes, which are usually square tubular. Upon impact, the energy-absorbing boxes collapse to absorb energy. Even with a strong impact, the rear of the vehicle can be damaged. Off-road vehicles are more prone to accidents when traversing mountainous terrain, and rear-end collisions or other accidents can easily damage the vehicle body, resulting in higher repair costs. To improve the protective performance of rear bumper beams, a rear bumper anti-collision tube beam for off-road vehicles has been developed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model discloses a rear bumper anti-collision tube beam for off-road vehicles, including: a rear anti-collision tube beam; the rear anti-collision tube beam has a mounting base and a tube beam, one end of the mounting base is a fixing plate with a fixing hole, the other end of the mounting base has two limiting parts, the mounting base is triangular in shape, the two limiting parts are distributed on the upper and lower sides of one corner of the mounting base, the fixing plate is located on the opposite side of this corner, the limiting part has a limiting plate and a reinforcing block, the reinforcing block connects the limiting plate and the mounting base respectively, the tube beam and the limiting plate are fitted and welded together, the upper and lower side edges of the mounting base are provided with crumple grooves, the interior of the mounting base is hollow, and the left and right sides have through holes.

[0005] Furthermore, the aforementioned tube beams are arranged in parallel vertically.

[0006] Furthermore, the cross-section of the aforementioned limiting plate is arc-shaped.

[0007] Compared with the prior art, this application can achieve the following technical effects:

[0008] The mounting base of this utility model is an energy-absorbing box. The triangular block-shaped energy-absorbing box has a large force-bearing area and high impact resistance. The parallel tube beams have a large protective area, thereby improving the protective performance of the rear anti-collision beam.

[0009] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. Attached Figure Description
