Collision energy absorption mechanism of passenger car and passenger car using mechanism

Abstract

The invention relates to a collision protection device of a passenger car, in particular to a collision energy absorption mechanism of a passenger car and the passenger car using the mechanism. The collision protection device of the passenger car comprises an energy absorption box and a buffer rod, wherein the buffer rod is fixedly assembled on a bumper of the passenger car and extends in a front direction and a rear direction; a friction buffer member is assembled in the energy absorption box; a friction buffer head is arranged at the rear end of the buffer rod; and a stagnation hole corresponding to the friction buffer head and allowing the friction buffer head to be inserted backward is formed in the friction buffer member and is smaller than the friction buffer head corresponding to the hole. Compared with a movable friction plate and a fixed friction plate in the prior art, the energy absorption efficiency of the collision energy absorption mechanism occupies absolute advantages; and the energy absorption efficiency is improved, the size of the energy absorption box is reduced correspondingly as well, and the box is prevented from occupying too much space. In conclusion, the collision energy absorption mechanism of the passenger car not only has the advantage of small size, but also solves the problem of poor buffering effect of a conventional energy absorption device.

Description

technical field [0001] The invention relates to a passenger car collision protection device, in particular to a passenger car collision energy absorption mechanism and a passenger car using the same. Background technique [0002] At present, there are many researches on the crash safety of passenger cars at home and abroad, and various relevant standards have been formulated, but there are relatively few studies on the frontal crash of passenger cars. In a passenger car, the collision energy can be absorbed by the deformation of its front bumper and the engine compartment. In contrast, due to the limited front space of a passenger car, it is usually impossible to install a corresponding energy-absorbing mechanism. It mainly relies on the deformation of the front wall and the frame longitudinal beam to absorb the collision energy. The collision safety is obviously extremely poor, and it is easy to cause casualties of the occupants. [0003] In view of the above situation, th...
