AI Technical Summary

Technical Problem

In the prior art, the front anti-collision beam installed on the front of the commercial vehicle will cause a significant impact on the internal occupants of the vehicle when it hits.

Method used

Design a collapse energy-absorbing protection structure, including a cross beam, a mounting bracket and a collapse rod. The cross beam is located at the front end of the vehicle, the mounting bracket is fixed to the frame, the collapse rod is connected between the mounting brackets, and an energy-sucking hole is provided on the collapse rod. In the event of a collision, the beam, collapse rod and mounting bracket can collapse and deform in an orderly manner, absorbing impact energy step by step.

Benefits of technology

It effectively reduces the impact and damage to the other structures and crew members of the collision and solves the impact of the front anti-collision beam of commercial vehicles on the occupants in the prior art.

Abstract

The invention relates to the technical field of vehicle collision avoidance, and provides a crumple energy-absorbing protection structure and a vehicle, and the crumple energy-absorbing protection structure comprises a cross beam, two mounting brackets and a crumple rod. The two installation supports are both installed on the rear side of the cross beam, the two installation supports are arranged in the length direction of the cross beam in a spaced mode, and the two installation supports are configured to be connected with a vehicle frame of the vehicle. The crumple rod is installed on the rear side of the cross beam and located between the two installation supports, one end of the crumple rod is connected with one installation support, the other end of the crumple rod is connected with the other installation support, and the crumple rod is provided with a plurality of first energy absorption holes. According to the collapse energy absorption protection structure, the two installation supports are installed on the rear side of the cross beam and used for being fixedly installed on the vehicle frame, so that the cross beam can directly bear collision of objects in front and deform to absorb energy; when the cross beam is collided, the cross beam, the collapsing rod and the mounting bracket can be collapsed and deformed orderly, and a large amount of impact energy can be absorbed by collapsing step by step.
