When the torque difference between the input portion 321 and the output portion 322 exceeds a preset threshold, the connection portion enables the input portion 321 and the output portion 322 to rotate relatively, in other words, when the manual opening/closing cover 200 exceeds a certain threshold force value, the connection portion acts to enable the input portion 321 and the output portion 322 to rotate relatively. In the normal opening and closing process, the motor 310 drives the input portion 321 to rotate, and the output portion 322 and the input portion 321 rotate synchronously to drive the hinge 210 to rotate. When the cover plate 200 needs to be opened manually or by mistake, the input portion 321 and the output shaft 311 of the motor 310 are kept relatively fixed, and when the torque difference between the output portion 322 and the input portion 321 exceeds a preset threshold, the connection portion enables the output portion 322 and the input portion 321 to rotate relatively, so that damage to the clutch device 320 or the motor 310 is avoided, and the charging port is ensured to be opened and closed manually.
