Mistaken touch prevention electric window breaker circuit and electric window breaker

Abstract

The invention relates to a mistaken touch prevention electric window breaker circuit and an electric window breaker. The electric window breaker circuit comprises: a switch assembly which is used for generating a switch signal; a trigger module which is in signal connection with the switch assembly, and is used for receiving the switch signal and generating a specific trigger signal after receiving the switch signal; and a receiving module which is in signal connection with the triggering module, and is used for receiving the identification triggering signal, generating and outputting a window breaking instruction after receiving the identification triggering signal, and controlling the electric window breaking device to break the window. The electric window breaker comprises the electric window breaker circuit. The receiving module can control the electric window breaking device to break the window only when receiving the specific triggering signal, the good external signal interference prevention performance, the good wiring false triggering prevention performance and the good line collision triggering prevention performance are achieved, false triggering of the electric window breaking device can be effectively prevented, and the safety and reliability of the electric window breaking device are improved.

Description

technical field [0001] The disclosure relates to the technical field of window breakers, in particular to an electric window breaker circuit and an electric window breaker for preventing false touches. Background technique [0002] The window breaker is an emergency escape device used in closed cabins such as automobiles. When a fire occurs in a closed cabin or falls into water and other emergencies, the window breaker can be used to quickly break the glass of the window to achieve rapid escape. The electric window breaker is a kind of window breaker, which is often used in large vehicles such as buses and coaches. The electric window breaker usually includes a mechanical switch, a motor, a window hammer and a drive circuit. The mechanical switch communicates with the electric drive circuit through the drive circuit. Electromechanical connection, the motor is linked with the window breaking hammer. When a dangerous situation occurs, the driver controls the motor to start thr...

AI Technical Summary

Problems solved by technology

[0004] In the actual use of the electric window breaker, since the electric window breaker is usually integrated and installed on the console of the car, the wiring at the installation position is very complicated, and external signal interference is prone to occur, which makes the electric window breaker The window device has a certain risk of false triggering, especially in the daily maintenance process of the line, it is easy to cause wiring errors and line damage, and it is easy to touch the line. When the drive circuit is accidentally connected to high / low level, it will cause The electric window breaker is activated immediately to break the window, resulting in the phenomenon of false triggering and breaking the window. In the case of false triggering, all the window glass will be broken, which will bring about a large property loss and a large safety hazard.
