Intelligent translational energy absorption seat used for self adaptation during rear-end collision

Abstract

The invention relates to an intelligent translational energy absorption seat used for self adaptation during a rear-end collision. In case of an accident, the intelligent translational energy absorption seat works as follows: a collision sensor mounted on the seat transmits information to a processing device according to the detected collision degree; the processing device processes the information, transmits an instruction to motors, controls the motors to rotate, and further drives sliding blocks to slide; when the collision sensor detects a high-speed rear-end collision, the motors rotate to drive the sliding blocks to slide, and the sliding blocks extrude energy absorbing steel sheets, so that the energy absorbing steel sheets are subjected to plastic deformation, the constraint platform force is further improved, and the seat is enabled to slide backwards steadily so as to protect a passenger from being injured in the neck. The intelligent translational energy absorption seat is suitable for three working conditions, namely low-speed rear-end collision, medium-speed rear-end collision and high-speed rear-end collision, and can provide larger constraint platform force for the high-speed rear-end 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.
