Over-temperature protection device and method of electronic speed regulator

Abstract

The invention discloses an over-temperature protection device and method of an electronic speed regulator, relates to the related field of electronic speed regulators, and aims at solving the problems that an existing over-temperature protection device is automatically powered off for protection after the temperature is too high, a switch needs to be reset manually after the temperature returns to normal, and the process is tedious. An inner cavity is formed in a mounting shell, a fixed frame is arranged in the middle of the upper end of the interior of the mounting shell, a movable frame is arranged at the lower end of the fixed frame, buffer springs are arranged on the two sides between the movable frame and the upper end face of the interior of the mounting shell, and a temperature sensing air bag is arranged in the middle of the interior of the movable frame. A pressing plate is arranged at the lower end of the movable frame, a connecting conducting strip fixing unit is fixedly connected to the lower end of the upper connecting block, a lower connecting block is fixedly connected to the middle of the lower end of the connecting conducting strip fixing unit, and a supporting spring is arranged between the lower connecting block and the lower end of the interior of the mounting shell.

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...

Problems solved by technology

[0004] The purpose of the present invention is to provide an electronic governor over-temperature protection device and its protection method to solve the problem that the current over-temperature protection device proposed in the background technology automatically cuts off the power after the temperature is too high, but the temperature returns to normal. The need to manually reset the switch, the process is more cumbersome
