The second end surface is the peripheral area of ​​the second cavity.

[0065] In the present disclosure, a groove is formed on one of the first end face and the second end face, and a protrusion is formed on the other of the first end face and the second end face. When the shell 100 and the cover body 200 are installed together, at least a portion of the protrusion is located in the groove, thereby forming a sealed connection between the shell 100 and the cover body 200.

In a specific embodiment, the sealing component 900 can be a component made of a deformable material such as a rubber ring or a silicone ring.

[0069] Refer to Figure 1 and Figure 3 In the present disclosure, the driving device 300 may be a motor, such as a DC motor or other device capable of generating power, thereby, the driving device 300 can generate driving force. In one embodiment, a shock absorbing component 301 may be provided at at least one end of the driving device 300, thereby, the motor is not directly supported by the housing 100 and the cover 200, but is indirectly supported by the housing 100 and the cover 200 through the shock absorbing component 301, and the provision of the shock absorbing component 301 can reduce the vibration transmitted by the motor to the housing 100 and the cover 200, so that the electric tail wing driving system of the present disclosure can have less noise and vibration as a whole.

[0070] The driving device 300 is used to drive the first transmission component 400 to rotate; specifically, the first transmission component 400 is a first worm, and the first transmission component 400 and the driving device 300 have the same rotation axis.

[0071] In the present disclosure, the driving device 300 is connected to the first transmission component 400 via a coupling 302. More preferably, the coupling 302 may be an elastic coupling, so that the vibration outputted by the motor to the first transmission component 400 is reduced by the setting of the elastic coupling, so that the transmission of the electric tail drive system of the present disclosure is more stable.

[0072] In a specific embodiment, one end of the first transmission component 400 is connected to the driving device 300 through a coupling 302, and the other end of the first transmission component 400 can be rotatably supported by the housing 100 and the cover 200 through a bearing.

[0074] Figure 5 It is a partial structural schematic diagram of an electric tail wing drive system according to one embodiment of the present disclosure.

[0075] In a specific embodiment, Figure 5 As shown, the second transmission component 500 includes a first end and a second end, and a first worm gear is formed on the outer surface of the second transmission component 500 (or, the second transmission component 500 includes a first worm gear), and the first worm gear is close to the first end of the second transmission component 500, wherein the first worm gear is connected to the first worm gear, thereby, the first transmission component 400 can drive the second transmission component 500 to rotate.

[0076] Furthermore, the second transmission component 500 includes a second worm gear, and the second worm gear is disposed close to the second end of the second transmission component 500 .

[0078] The second transmission component 500 is in transmission connection with the output shaft 700, and the second transmission component 500 drives the output shaft 700 to rotate; in a preferred embodiment, a second worm gear 701 is provided on the output shaft 700, and the second worm cooperates with the second worm gear 701, so that when the second transmission component 500 rotates, it can drive the output shaft 700 to rotate, and accordingly, power is output outwardly through the output shaft 700.

[0079] In the present disclosure, the second worm gear and a portion of the output shaft 700 are disposed in the accommodation space, that is, both ends of the output shaft 700 are located outside the housing 100 and the cover 200 .

[0080] like Figure 5As shown, the elastic component 600 is used to apply elastic force to the second transmission component 500, and the elastic force will cause positive pressure to exist between the second transmission component 500 and the output shaft 700. In addition, through the arrangement of the elastic component 600, the center distance between the second transmission component 500 (second worm) and the output shaft 700 (second worm wheel) can be reduced, thereby reducing side suction and improving the self-locking property of the electric tail wing drive system disclosed in the present invention.

[0081] More preferably, the elastic component 600 is provided only at the second end of the second transmission component 500, so that in a stationary state, the elastic component 600 can lift up the second end of the second transmission component 500. At this time, the second transmission component 500 will swing slightly with its first end as a fixed point, and the center distance between the second worm and the second worm wheel can be reduced, thereby reducing the side clearance and improving the self-locking property.

[0082] In the present disclosure, bearings are provided at both ends of the second transmission component 500, and the bearings can be supported on the housing 100 or the cover 200, and enable the second transmission component 500 to rotate. Accordingly, the elastic component 600 is arranged to contact the bearing provided at the second end of the second transmission component 500, and can apply elastic force to the bearing, thereby, the elastic component 600 is arranged close to the second end of the second transmission component 500, and the force application point of the elastic component 600 to the second transmission component 500 is close to the second end of the second transmission component 500.

That is, the second bending portion 622 can extend from the other end of the first bending portion 621 toward the direction close to the base 610, and the second bending portion 622, the first bending portion 621 and part of the base 610 together form a roughly triangular shape.

[0090] At this time, a portion of the outer surface of the second bent portion 622 can contact the bearing, so that an elastic force is applied to the bearing through the second bent portion 622. In a preferred embodiment, the elastic component 600 can be made of materials such as spring steel.
