Automatic window breaking device for vehicles falling into water

Abstract

The invention discloses an automatic window breaking device for vehicles falling into water and relates to the technology of vehicle distress escape. The device comprises an air cylinder body arranged at the front side of the vehicle window glass, wherein one end of the air cylinder body is an open end, the other end of the air cylinder body is provided a bottom surface, the open end of the air cylinder body is provided with an air generator, the bottom surface of the air cylinder body is provided with a through hole, the inner wall of the air cylinder body is glidingly matched with a piston, the bottom surface of the piston near the air cylinder body is provided with a collision head, and the collision head is glidingly matched with the through hole. When the vehicle falls into water and is in danger, the air generator is triggered and generates a large amount of high-pressure air in the short time, the high-pressure air pushes the piston to move, and the collision head arranged on the piston extends out of the outer side through the through hole arranged in the bottom surface of the air cylinder body, so the glass window is broken, the action is fast, and the reliability is high.

Description

technical field [0001] The invention relates to a vehicle emergency escape technology, in particular to an automatic window breaking device for a vehicle that falls into water. Background technique [0002] At present, when danger occurs, the vehicle's window-breaking tool is mainly a safety hammer on the vehicle. The main structure of the safety hammer consists of a metal impact head, a plastic shaft and a handle. When a dangerous situation occurs in the vehicle, the passenger takes off the safety hammer and hits the window glass to break the glass for escape, but breaking the glass requires relatively large strength. , it is more difficult for some people with relatively small strength to break the glass; in addition, the safety hammer must be used by a person to complete the broken window; When these vehicles fall into the water, the occupants are often highly nervous, and it is difficult to select the right tool at the first time and break the glass at the right positio...
