Releasing device capable of automatically bouncing off in case of power failure

Abstract

The invention discloses a releasing device capable of automatically bouncing off during power failure, and relates to the technical field of switches, the releasing device comprises an electric control assembly, an electromagnet assembly and a permanent magnet assembly, the electric control assembly is fixedly connected with the electromagnet assembly, the electromagnet assembly comprises an electromagnet body, the permanent magnet assembly comprises a permanent magnet body, and the electric control assembly is further connected with a power supply; when the power source is powered on, the electromagnet body is powered off, and the electromagnet body and the permanent magnet body attract each other. When the power supply is cut off, the electromagnet body is electrified, and the magnetic pole of the electromagnet body is the same as that of the permanent magnet body. The electromagnet assembly and the permanent magnet assembly can attract each other when powered on and repel each other when powered off, and therefore the opening and closing mechanism connected with the electromagnet assembly and the permanent magnet assembly can be opened under the power-off condition.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to a release device that automatically pops open when power is off. Background technique [0002] Opening and closing mechanisms can be seen everywhere in people's lives, such as opening and closing windows, opening and closing doors, or opening and closing box covers. In general, most of them are manual switches, but more advanced opening and closing mechanisms use electric control mechanisms. [0003] However, once the electronically controlled opening and closing mechanism is powered off, it will fail, causing the opening and closing mechanism to fail to open or normally close. When a danger occurs, such as a fire, the opening and closing mechanism cannot be normally opened or closed due to a power failure, which will cause people to face danger. [0004] Therefore, there is an urgent need in the market for a power-off and automatic pop-up release device to solve the above prob...
