An over-temperature protection device and protection method for an electronic governor

Abstract

The invention discloses an over-temperature protection device of an electronic governor and a protection method thereof, and relates to the related field of the electronic governor. In order to solve the problem that the current over-temperature protection device automatically cuts off the power after the temperature is too high, but the temperature returns to normal Need to manually reset the switch, the process is more cumbersome. The interior of the installation housing is provided with an inner cavity, the middle of the upper end of the installation housing is provided with a fixed frame, the lower end of the fixed frame is provided with a mobile frame, and the distance between the mobile frame and the upper end surface of the installation housing is There are buffer springs on both sides of the space, a temperature-sensitive air bag is set in the middle of the moving frame, a pressure plate is set on the lower end of the moving frame, and a connecting conductive sheet fixing unit is fixedly connected to the lower end of the upper connecting block. A lower connection block is fixedly connected to the middle of the lower end of the conductive sheet fixing unit, and a supporting spring is arranged between the lower connection block and the lower end inside the installation housing.

Description

technical field [0001] The invention relates to the related field of electronic speed governors, in particular to an over-temperature protection device for electronic speed governors and a protection method thereof. Background technique [0002] The full name of ESC is electronic speed controller, English Electronic Speed ​​Control, referred to as ESC. According to the different motors, it can be divided into brushed ESC and brushless ESC. The speed measurement and stabilization signal of the electronic speed governor is generated by electrical methods. Rotating speed. The electronic speed controller generally has a power output function, that is, there is a voltage output of about 5V between the positive and negative poles of the signal line, which supplies power to the receiver through the signal line, and the receiver supplies power to the steering gear and other control equipment. [0003] Most of the current over-temperature protection devices detect that the temperat...
