AI Technical Summary
In existing power-closing energy storage switches, the motor is connected to the energy storage structure, which requires high-precision control of the motor. If the motor continues to operate, it will cause the energy storage to become saturated, which can easily burn out the motor and damage the energy storage mechanism.
The motor and the switch are set separately. The switch is limited by the limit seat. The motor is only responsible for driving the rotating energy storage block. After the rotating energy storage block is separated from the switch, it can rotate freely, avoiding excessive energy storage by the motor and reducing costs by using a common motor.
This avoids the situation where the motor burns out due to excessive energy storage, increases the ease of use and practical value of the device, and reduces the dependence on high-precision motors.
