Collision protection assembly and commercial vehicle

Abstract

The invention relates to a collision protection assembly and a commercial vehicle. The collision protection assembly comprises an energy absorption module which comprises a plurality of energy absorption units, and each energy absorption unit comprises a first energy absorption piece and at least two second energy absorption pieces; one ends of all the second energy-absorbing pieces are intersected, and the other ends of all the second energy-absorbing pieces extend radially; the first energy absorption piece is supported at the intersection of all the second energy absorption pieces in a deformable mode in the first direction; every two adjacent energy absorption units are in force transmission connection through at least part of the second energy absorption pieces of the energy absorption units. When one energy absorption unit or multiple energy absorption units of the collision protection assembly are impacted, every two adjacent energy absorption units are in force transmission connection through at least part of the second energy absorption pieces of the energy absorption units, and the impacted energy absorption units can transmit impact force to the adjacent energy absorption units through the second energy absorption pieces of the energy absorption units; and the impact force continues to be transmitted to other adjacent energy absorption units through the energy absorption unit, so that dissipation and conduction of the collision load are achieved, and local crushing caused by instability of the protection assembly is avoided.

Description

technical field [0001] The present application relates to the technical field of automobile collision protection, in particular to a collision protection assembly and a commercial vehicle. Background technique [0002] Due to the limited length of the front part of the flat-top commercial vehicle, the cab lacks sufficient buffer and energy-absorbing space and devices. Usually, in the event of a frontal collision accident, the front part of the cab will undergo severe intrusive deformation, resulting in the occupants not being effectively Protect. [0003] At present, since the overall size of the cab needs to meet the regulations and design requirements, the method of partially strengthening the front body structure of the cab is often used to ensure that it has sufficient crashworthiness. [0004] However, although the above-mentioned method improves the structural strength of the front of the cab, it is limited by the lack of space in the front of the cab of a flat-top co...

Problems solved by technology

[0005] Based on this, it is necessary to provide a collision protection assembly and a commercial vehicle that can make up for the defects of poor collision buffer performance in view of the problem that the current cab front body structure reinforcement method has poor collision buffer performance.
