Vehicle impact protection system

Abstract

The invention discloses a vehicle impact protection system. The system includes a vehicle frame; the vehicle frame is connected with a buffer device through a bolt, and the rear end of the buffer device is welded on a skeleton of a bumper bar; the front end of the vehicle frame is provided with a collision sensor. When the vehicle frame is collided, the collision sensor sends data to a vehicle-mounted controller, the vehicle-mounted controller judges the acceleration of the vehicle through the collision sensor, if the speed exceeds a threshold, an anti-impact device in the buffer device is started, and the kinetic energy given by the anti-impact device is made use of for reducing the impact on the vehicle; the vehicle-mounted controller starts a safety airbag and an anti-collision cushionchair, and the impact on a cab is then reduced. The anti-impact device includes at least one anti-collision column, the upper end faces of the anti-collision columns are connected with the end face ofthe inner side of the upper portion of the buffer device, and the lower end faces of the anti-collision columns are connected with the end face of the inner side of the lower portion of the buffer device.

Description

technical field [0001] The invention relates to a protection system, in particular to a vehicle impact protection system. Background technique [0002] In the prior art, the front bumper of an automobile generally consists of a bumper frame structure made of unfilled structure, a shock absorber, connecting elements connecting the frame structure to the main body, and a bumper cover. [0003] The shock absorber of the bumper is a part that is used by the mounting layer to reduce the conduction of the shock generated during the Jehol collision to the subject, and the shock absorber is made of a natural rubber type material, but when in When comparing the elastic characteristics, its elasticity is not enough compared with the elasticity obtained by applying the improvement, so the present invention does not adopt the generally used foam filling structure, but selects the mechanical structure to supplement the elastic force. At the moment of collision, the energy can be Absorb ...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the protection method is single, and the user cannot be protected from crossing. When the speed of the vehicle is too fast, there is no reverse impact force to quickly brake. The purpose is to provide a vehicle collision protection system to solve the above problems. The problem
