Description

Technical Field

[0001] The invention relates to the technical field of anti-collision beams for special vehicles, and in particular to a front anti-collision beam structure for special vehicles. Background Art

[0002] Special vehicles refer to vehicles whose overall dimensions, weight, etc. exceed the design vehicle limits and have special purposes. They are specially made or modified, equipped with fixed devices and equipment, and whose main function is not to carry people or goods. Special vehicles generally have special signs or special vehicle models.

[0003] The existing anti-collision beams of special vehicles, when in use, are mostly composed of two parts: a mounting beam and an anti-collision beam. The anti-collision effect is poor. When impacted, the energy generated by the impact cannot be gradually absorbed, causing the passengers to be subjected to a greater shock force. At the same time, the anti-collision beam is deformed after the impact and cannot effectively protect against subsequent impacts, thereby resulting in ineffective protection of the safety of special vehicles and the people inside the vehicle. Summary of the invention

At the same time, the anti-collision beam can be restored after collision, so that it can provide multiple protection effects, thereby improving the anti-collision performance of special vehicles. At the same time, when encountering a major collision, the impact force can be comprehensively decomposed and unloaded, thereby ensuring the safety of special vehicles and people inside the vehicles.

[0015] Beneficial effects of the present invention:

[0016] (1) The reverse buffer mechanism can effectively buffer and unload the impact of the collision, thereby achieving effective protection against smaller impact forces, improving the anti-collision effect of special vehicles, and ensuring the safety of the vehicle and the people inside the vehicle.
