Embodiment 1
[0045] refer to Figure 1 to Figure 12 , an electric small door actuator assembly on a fuel tank cover or a charging box cover for a vehicle, comprising:
[0046] The actuator housing 1 is arranged in the vehicle body and has an inner cavity 4 opened therein. Preferably, a waterproof plug 2 is provided at the inlet end of the actuator housing 1, and a skeleton oil seal 3 is provided at the output end (at the output device) of the actuator housing 1 to improve the overall waterproof and dustproof sealing performance and ensure that the internal Normal operation of electrical accessories;
[0047] A driving mechanism, which is arranged in the inner cavity 4, and is used to provide power, preferably a motor 5;
[0048] The electronic control device is used to control the operation of the drive mechanism and is electrically connected to the driving computer. The electronic control device mainly includes an ECU circuit board 6 arranged in the actuator housing 1 to realize communi...
Embodiment 2
[0063] Compared with the technical solution of Embodiment 1, this embodiment is equipped with a motor shaft sleeve 28 and a motor stopper 29 on the output shaft of the motor 5 (drive mechanism), so as to prevent the displacement of the worm gear structure when it is subjected to a lateral force. Thereby, relevant components can be stably maintained on their working positions, and the normal operation of the whole can be ensured.
Embodiment 3
[0065] Compared with the technical solutions of the above other embodiments, this embodiment integrates a resistive position sensor 30 on the ECU circuit board 6 for monitoring and feedbacking the position of the fuel tank cover or the charging tank cover.
