Tertiary automobile collision buffering device

Abstract

The invention relates to a tertiary buffering device for mitigation of automobile collision. The tertiary buffering device comprises a rubber layer, an airbag layer and a spring layer and can be mounted at one part, easy to have a collision, of an automobile, such as an automobile head, an automobile tail and side positions of the automobile. The rubber layer, the airbag layer and the spring layerare arranged in sequence from right to left; the rubber layer is bonded with the airbag layer through sticky connection; the airbag layer is fixedly connected with the spring layer through a bolt; the spring layer is fixed at one part easy to have a collision, such as the automobile head, the automobile tail and an automobile door, through a bolt; two pressure limiting holes are formed in the airbag layer and controlled by a pressure limiting opening mechanism; and when the pressure in the airbag layer reaches a preset value, the pressure limiting mechanism is started so that the air in an airbag enters into the pressure limiting holes via air holes in the two sides of the pressure limiting mechanism and are exhausted via air exhaust holes in the two sides of the spring layer. According to the tertiary buffering device, the impact force generated in the automobile collision process can be effectively neutralized, the damage degree of the automobile can be reduced, the passenger safetycan be protected, the manufacturing cost is low, and the device is effective and practical.

Description

technical field [0001] The invention belongs to the technical field of passive safety protection of motor vehicles, in particular to a buffer protection device which can play a buffer protection function when a vehicle collides with the rear, front or side. Background technique [0002] With the continuous increase of car ownership, roads are becoming more and more congested, road conditions are becoming more and more complex, traffic accidents occur frequently, and various collision accidents are common, the passive safety performance of cars is becoming more and more important. Existing passive safety protection for automobiles mainly includes seat belts, airbags, bumpers, etc., but the protective effect of these devices in actual accidents is very limited. At present, most of the passive safety protection measures of vehicles are to absorb the impact by damaging the front of the car, so as to reduce personal injuries. Therefore, the problem in the prior art is: in order ...
