Description

Technical Field

[0001] This utility model relates to a vehicle anti-collision beam and a vehicle, belonging to the field of automotive technology. Background Technology

[0002] In related technologies, the crash beam is fixed to an energy-absorbing box, which is connected to the vehicle body via a mounting bracket. The energy-absorbing box and the mounting bracket are fixed by welding, but the weld strength between them is low. In the event of a collision, the side welds between the energy-absorbing box and the mounting bracket are prone to tearing, thus reducing the operational stability of the crash beam and preventing it from effectively impacting the collision.

[0003] Application CN202021369924.6 discloses a vehicle anti-collision beam assembly and a vehicle. The anti-collision beam assembly includes: an anti-collision beam body; an energy-absorbing box, one end of which is connected to the anti-collision beam body; and a mounting bracket, the other end of which is connected to the energy-absorbing box and fixed to the vehicle body. The mounting bracket has at least one reinforcing portion at its end facing the energy-absorbing box, the reinforcing portion being adapted to push against the energy-absorbing box. According to this embodiment of the vehicle anti-collision beam assembly, by providing a reinforcing portion in the connection area between the mounting bracket and the energy-absorbing box, weld tearing between the energy-absorbing box and the mounting bracket can be avoided, thus preventing connection failure between the mounting bracket and the energy-absorbing box. This allows the energy-absorbing box to absorb energy stably and reliably, improving the operational stability of the anti-collision beam assembly and enhancing vehicle safety.

[0004] However, the device still has the following problems: the energy-absorbing box and the mounting bracket are fixed by welding, and the whole device needs to be replaced when only the anti-collision beam is deformed, which is costly and inconvenient to use.

[0005] Therefore, this utility model proposes a new solution. Utility Model Content

Therefore, the anti-collision beam body 1 can be stably supported, ensuring the strength of the anti-collision beam body 1. Furthermore, when only the anti-collision beam body 1 is deformed, it can be disassembled and replaced, saving costs. By installing a foam board 6 on the front of the anti-collision beam body 1, the foam board 6 can absorb energy when it hits a pedestrian at low speed, thereby protecting the pedestrian. By fixing multiple reinforcing ribs 7 to the outer wall of the front of the anti-collision beam body 1, the strength of the anti-collision beam body 1 is improved. A guide groove 8 is provided in the middle of the reinforcing rib 7. When an impact occurs, it can ensure the collapse deformation posture of the anti-collision beam and reduce the impact force transmitted to the passenger compartment.
