Crash safety seat device with crash threshold sensing function and working method thereof

Abstract

The invention discloses a collision safety chair device with a collision threshold induction function and an operating method of the device. The device is composed of an elastic bi-stability structural component, a gear set, a horizontal H-shaped gear block, a connecting gear block, a connecting rod, a guide rail and a limiting device, wherein both ends of the elastic bi-stability structural component are connected with an automotive chassis, the middle point of the elastic bi-stability structural component is connected with the horizontal H-shaped gear block through the connecting rod, the horizontal H-shaped gear block forms a movement mechanism with single freedom through the gear set and the connecting gear block, and the chair can move along a bi-stability skipping direction through the mechanism. The operating method of the device is that the injury caused due to collision acceleration can be effectively relieved through the device under the counter-acting force of the elastic bi-stability structural component when the automobile generates collision. The collision safety chair device is a pure mechanical structure, fast in response, high in reliability, and strong in anti-jamming capability, and the injury of personnel in the front row in the automobile can be effectively avoided when the automobile generates direct impact or offset impact, thus the collision safety chair device is suitable for many types of automobiles.

Description

technical field [0001] The invention relates to the technical field of automobile passive safety devices, in particular to a collision safety seat device with a collision threshold sensing function and a working method thereof. Background technique [0002] At present, in automobile collision accidents, the casualties caused by the lack of living space for drivers and passengers due to the deformation of the vehicle body account for a large proportion. In addition, the compression and deformation of the vehicle body make the occupants trapped in the vehicle due to the limited activity space, which can easily cause secondary casualties. The safety protection measures for vehicle collision accidents mainly include airbags, seat belts and other devices at present, but they cannot play a fundamental protective role against the extrusion damage caused by the deformation of the vehicle body. In addition, through the investigation of the crash safety seat, it is found that the des...

AI Technical Summary

Problems solved by technology

The disadvantage is that the process of the push rod to open the locking device is relatively complicated, and requires high precision, which may easily cause a failure that the device cannot be opened

[0004] 1) Slow response speed;

[0005] 2) Member damage caused by collision acceleration cannot be avoided

For example, in a collision accident, the seat collides with the device connected to it, causing the collision force to be directly transmitted to the driver. The greater acceleration will cause damage to the driver and passengers, and the reduction of the acceleration value during the collision cannot be achieved, and it cannot be avoided. Acceleration intervals that seriously harm the human body during the collision;

[0006] 3) The structure is complex and the applicable collision range is limited

Due to the use of special structures such as electro-hydraulic drive, sensor induction, etc., the seat can only move under a specific collision. If the collision position changes, the seat will be greatly reduced or lose its protective effect
