Front collision protection device for passenger car

Abstract

The invention relates to a front collision protection device for a passenger car. The front collision protection device comprises an installation bracket assembly, an outer barrel assembly, an inner barrel, a guide rod, a guide seat assembly, a piston assembly and a base assembly, wherein the inner barrel is embedded into the outer barrel assembly and is arranged coaxially with the outer barrel assembly; the guide seat assembly is arranged at the left end parts of the outer barrel assembly and the inner barrel; the piston assembly is embedded into the inner barrel; the base assembly is arranged at the inner side of the right end of the outer barrel assembly and the right end part of the inner barrel; the left end part of the guide rod is connected to the installation bracket assembly and the right end part sequentially passes through the guide seat assembly and the piston assembly and then is locked by a locking nut. The disadvantages in the prior art can be overcome; impact energy is absorbed during front collision of the passenger car; the impact force is hierarchically buffered; the front collision protection device has the characteristics of being high in relieving efficiency, reliable in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of passenger cars, in particular to a front collision protection device for passenger cars. Background technique [0002] At present, there are two types of common domestic traditional passenger car front collision protection devices, which use the front wall structure of the full load-carrying body to buffer the collision energy and use the staged structural destruction device to buffer the collision energy. However, these two types of structures have low mitigation efficiency and Vehicle damage is heavy and other deficiencies. Contents of the invention [0003] The purpose of the present invention is to provide a passenger car frontal collision protection device, which can solve the deficiencies in the prior art, absorb the impact energy when the passenger car has a frontal collision, buffer the impact force in stages, and have high mitigation efficiency, reliable structure and low cost. low-level f...
