Preferably, the upper shell and the lower shell are connected by a buckle.

During the use, motor drive gear group rotates, and the gear train drives half arc tooth executive component and moves, because half arc tooth executive component's connection slider and case lid connecting piece contact surface unevenness, when half arc tooth executive component rotated certain angle, connect the bellied position of slider and change the bellied position of case lid connecting piece, realized the top-open of case lid promptly, when half arc tooth executive component rotated certain angle again, connect the bellied position of slider and change the sunken position of case lid connecting piece, realized the closure of case lid promptly.

The utility model has the advantages and the beneficial effects that: the utility model relates to an automatic opening and closing actuator of an automobile charging cover, which can convert a small force value output by a motor into a large force value through a gear set according to the preset or real-time working condition requirement and then transmit the large force value to a target through a gear combination clutch mechanism; the gear set can play a role in increasing output force and also can play a role in protecting the motor when the mechanism is impacted by reverse force. In addition, gear train and supporting clutching mechanism (i.e. half arc tooth actuating assembly), the operating mode limitation that can avoid worm gear and worm and rack, for example: large noise, small force value, unadjustable speed during operation and no gap output. In addition, there is the object to support the case lid when the case lid outside, causes the case lid to open smoothly, and when case lid connecting piece lock was dead, for preventing to connect the slider and the case lid takes place violent friction and lead to the damage of connecting the slider, the utility model relates to a spring structure can cushion this kind of friction of connecting slider and case lid.
