An active child airbag vest device and its control method

Abstract

The invention discloses an active child airbag vest device and a control method thereof, comprising a vest body, a zipper, a lock A, a lock B, a lock C, a lock D, a lock tongue A, a lock tongue B, a lock Buckle tongue C, lock tongue D, webbing A, webbing B, webbing C, webbing D, retracting mechanism, tightening mechanism, deflation control mechanism, inflation port, knob, pressure sensor, vehicle speed sensor, roll angle sensor, side Force sensor, main switch, information storage unit, ECU. Before the child gets on the bus, the car staff will input the child's height and weight information into the information storage unit, and the ECU will control the work of the retracting mechanism according to the child's height and weight information in the information storage unit; the ECU will control the opening and closing of the deflation control mechanism in real time Closing and opening; the ECU receives detection information from pressure sensors, vehicle speed sensors, roll angle sensors, and lateral force sensors as basis for judgment and control. The invention can effectively avoid or reduce children's injury.

Description

technical field [0001] The invention belongs to the field of automobile safety, and in particular relates to an active child airbag vest device and a control method thereof. Background technique [0002] As the main means of transportation for picking up and dropping off children from school, school buses have increasingly received widespread attention in the society for their collision safety. At present, the restraint devices equipped on school buses are mainly safety belts (including two-point safety belts or three-point safety belts). [0003] When a school bus collides head-on, because the contact area between the seat belt and the child's chest and abdomen is small, the seat belt itself will exert a large squeezing force on the child's chest and abdomen, and the child's bones and muscles are not fully developed. , thus easily causing injury to children; in addition, because children are lively and active by nature, they often appear in an "off-position" sitting postur...

AI Technical Summary

Problems solved by technology

[0003] When a school bus collides head-on, because the contact area between the seat belt and the child's chest, abdomen and other parts is small, the seat belt itself will exert a large squeezing force on the child's chest and abdomen, and the child's bones and muscles are not fully developed. , thus easily causing injury to children; in addition, because children are lively and active by nature, they often appear in an "off-position" sitting posture when riding a school bus, which greatly reduces the protective effect of seat belts, and even causes additional damage to children in the "off-position" sitting posture. serious injury

[0004] When the school bus rolls, rolls, or collides with the side, the protection effect of the seat belt is not good enough to effectively restrain the movement of the child, causing the child to leave the original seat and collide violently with other people or objects; additional serious injury to a child in a "sitting" position
