An adaptive intelligent translational energy-absorbing seat for rear-end collision

Abstract

The invention relates to an intelligent translation energy-absorbing seat for self-adaptation under rear-end collision. When an accident occurs in the intelligent translational energy-absorbing seat, the collision sensor installed on the seat transmits the information to the processing device according to the detected collision degree. The sliding of the sliding block, when the collision sensor detects that the degree of tail collision is a high-speed tail collision, the motor is driven to drive the sliding block to slide, and the sliding block squeezes the energy-absorbing steel sheet to cause plastic deformation of the energy-absorbing steel sheet, further improving the constraint platform force, Realize the stable back sliding of the seat to protect the occupant's neck from injury. The intelligent translational energy-absorbing seat of the present invention is suitable for three working conditions of low-speed tail collision, medium-speed tail collision and high-speed tail collision, and can provide a relatively large restraining platform force for high-speed tail collision.

Description

technical field [0001] The invention mainly relates to an intelligent translational energy-absorbing seat for self-adaptation under rear-end collision, and belongs to the technical field of automobile active safety. Background technique [0002] Rear-end collision accidents are one of the most common types of collisions on the road. Although the fatal injuries to occupants are relatively small, the social costs of whiplash injuries caused by rear-end collision accidents are relatively large. Whiplash injury refers to the injury caused by the whipping movement of the occupant's neck in a rear-end collision. At present, the mechanism of its injury is not clear, but it is generally believed that reducing the relative movement of the occupant's torso and head can reduce whiplash injuries. At the same time, some car manufacturers have produced seats that reduce whiplash injuries based on this understanding. proved to be effective. At present, the existing neck protection seats ...

AI Technical Summary

Problems solved by technology

At present, the existing neck protection seats for rear-end collision occupants in the market have disadvantages such as single protection form, poor protection performance and poor universal applicability.

[0003] For example, patent CN2010102008438 discloses a translational energy-absorbing seat for neck protection in rear-end collisions, which plays a certain role in protecting the neck of the occupant, but also has some shortcomings, such as: a. The applicable working conditions are single, only Applicable to medium and low-speed rear collisions, but cannot provide a large restraining platform force for high-speed rear collisions

b. The protection performance is single. In case of a secondary collision of the vehicle, the seat will slide forward, which will easily cause other injuries to the occupants.
