[0034] In the embodiment of the present application, a first sealing ring 3 and a second sealing ring 4 are provided to seal the connection between the output shaft 2 and the actuator housing 1. The second sealing ring 4 abuts against the first sealing ring 3 to squeeze and seal, which can improve the waterproof and dustproof performance, thereby increasing the protection level of the actuator from IP54 to IP67, thereby completely solving the problem of functional failure caused by insufficient protection performance of functional parts.

[0035] like Figure 2 , Figure 3 As shown, the outer wall of the first sealing ring 3 is arc-shaped and convex; the clamping groove 41 is arc-shaped and concave, and the shape of the clamping groove 41 matches the shape of the outer wall of the first sealing ring 3. In this way, the first sealing ring 3 and the second sealing ring 4 can be matched without gap, and the second sealing ring 4 and the first sealing ring 3 can be abutted and squeezed to seal, which can improve the waterproof and dustproof performance and ensure that the protection level of the actuator is increased from IP54 to IP67.

[0036] Preferably, the first sealing ring 3 is an O-ring, the structure of which facilitates the rotational sealing of the output shaft 2, and realizes interference connection between the groove 41 of the second sealing ring 4 and the outer surface of the O-ring.

[0037] like Figure 2 , Figure 3As shown, the second sealing ring 4 is coaxially arranged with the output shaft 2, and the cross section of the second sealing ring 4 is T-shaped. The second sealing ring 4 includes an annular ring 42 and an annular boss 43.

The outer circumferential surface 422 of the annular ring 42 is connected to the first through hole 11 of the actuator housing 1 by snap-fitting or interference fitting, so that the annular ring 42 is stably fixed in the first through hole 11 of the actuator housing 1.

[0039] The inner diameter of the annular ring 42 is smaller than the inner diameter of the annular boss 43 , so that the cross section of the second sealing ring 4 located on each side of the output shaft 2 is T-shaped.

[0040] Preferably, the actuator further comprises a sealing end cover (not shown), which is connected to one side of the actuator housing 1 provided with the first through hole 11; the sealing end cover is provided with a third through hole corresponding to the first through hole 11, the output shaft 2 passes through the third through hole, and the edge of the third through hole abuts against the second sealing ring 4 to press the second sealing ring 4 against the first sealing ring 3.

The glue potting sealing layer 8 can further improve the sealing performance of the input wiring harness 6, avoid the risk of water ingress, improve the sealing effect, and improve the waterproof and dustproof performance, thereby improving the protection level of the actuator from IP54 to IP67.

[0048] The input wiring harness 6 is sealed by the sealing plug 7 and the glue-filled sealing layer 8, which can improve the sealing effect and the waterproof and dustproof performance, thereby improving the protection level of the actuator from IP54 to IP67.
