A compressed air energy storage bus window breaking device

Abstract

The invention relates to a compressed air energy storage passenger car window breaking device, and belongs to the technical field of passenger car rescue and safety. The window breaking device comprises a cylinder body and an actuation device, and is characterized in that the cylinder body includes an upper cylinder body and a lower cylinder body; the upper cylinder body is provided with an intake hole for achieving the effects of air storage and drainage; the actuation part is mounted on the lower cylinder body, and includes a percussion handle, a sealing pressure rod, a guide sleeve and a piston impact head; the lower cylinder body is divided into a guide cavity and a working cavity; the guide cavity is provided with the sealing pressure rod and the guide sleeve; the end of the sealing pressure rod is connected with the percussion handle by a thread; and the working cavity is provided with the piston impact head. The pneumatic window breaking machine with the structure is mounted on a glass car window angle; a high-pressure air source is leaded in from the intake hole of the upper cylinder body; the percussion handle is powerfully pressed down; a gap is formed between the sealing pressure rod and the guide sleeve; high-pressure air currents enter the working cavity from the guide cavity of the lower cylinder body; and the piston impact head is popped out under the effect of high-pressure gas to break car window glass.

Description

technical field [0001] The invention belongs to the technical field of passenger car lifesaving and safety, and in particular relates to a window breaking device for compressed air energy storage passenger cars. Background technique [0002] As one of the main highway passenger transport vehicles, passenger cars occupy a considerable proportion in short- and medium-distance passenger transport. In order to improve the comfort of vehicles and enhance the competitiveness of passenger vehicle products, passenger vehicle manufacturers have installed high-strength tempered glass on passenger vehicles. Tempered glass has brought safety hazards while protecting passengers. Once accidents such as fire, falling into water, overturning or violent impact occur in the passenger car, it is difficult for passengers to escape safely and timely only by the exit of the passenger car. At present, the automobile safety glass hammer usually installed on the passenger car is very easy to panic ...

AI Technical Summary

Problems solved by technology

In order to improve the comfort of cars and enhance the competitiveness of passenger car products, passenger vehicle manufacturers have installed high-strength tempered glass on passenger cars. Tempered glass has brought safety hazards while protecting passengers.

In case of accidents such as fire, falling into water, overturning or violent collision, it is difficult for passengers to escape safely and timely only by the exit of the bus.

At present, the automobile safety glass hammer usually installed on the passenger car is very easy to panic when the passenger car breaks out, falls into the water or rolls over, and it is difficult to use it correctly.
