The rotating shaft 545 of the push-pull output piece 422 is fixedly sleeved with a push-pull output gear 43, and the push-pull output gear 43 is meshed with the push-pull gear.

In this embodiment, the push-pull output member 422 is a worm, the push-pull member 41 is a worm bar, and when the worm bar contacts with the worm, the worm is meshed with the worm bar, and the push-pull driving motor 421 drives the worm to rotate through the push-pull gear set, so as to drive the worm bar to move in a direction approaching or separating from the housing 1.

In this embodiment, when the push-pull driving motor 421 rotates forward, the worm drives the worm bar to move in a direction approaching to the housing 1; when the push-pull driving motor 421 is reversed, the worm drives the worm bar to move in a direction away from the housing 1. In other embodiments, the movement of the scroll bar may be opposite to the direction set by the present embodiment when the push-pull driving motor 421 is rotated forward and backward.

In this embodiment, the push-pull output member 422 is a worm, the push-pull member 41 is a worm rack, and the worm rack is preferably a rectangular tooth, so that the radial force in the transmission process of the worm rack can be reduced, the axial thrust of the worm rack transmission can be increased, and the transmission efficiency and stability can be improved. In other embodiments, the push-pull output member 422 may be a screw rod, and the push-pull member 41 may be a deformed nut, i.e., a nut bar obtained by taking 1/2-1/5 of the nut along the circumference of the long nut and expanding the nut.

In this embodiment, to facilitate the engagement between the push-pull member 41 and the push-pull output member 422, the housing 1 is provided with a push-pull through hole, and the push-pull member 41 can extend into the push-pull through hole to engage with the push-pull output member 422, and at the same time, the push-pull output member 422 partially extends into the push-pull through hole to reduce the required length of the push-pull member 41.

When the clutch mechanism drives the push-pull output member 422 to contact with the push-pull member 41, the initial contact position is not necessarily the engagement position, so as to assist the smooth engagement of the push-pull output member 422 and the push-pull member 41, the clutch output rack 535 is slidably disposed on the fixed box 52 and can move along the length direction of the clutch output rack 535. And one end of the clutch output rack 535 far away from the push-pull driving assembly 42 is connected with one end of the first elastic element 536, the other end of the first elastic element 536 is connected with the fixed box 52, and the extending and retracting direction of the first elastic element 536 is the same as the setting direction of the clutch output rack 535.

Because the first elastic element 536 is provided, and the clutch output rack 535 is slidably disposed on the fixed box 52, when the push-pull output member 422 and the push-pull member 41 are in a state of being in contact with the tooth top and the tooth top, the sliding box 51 cannot be driven to slide continuously by the rotation of the clutch driving motor 531, and the clutch output rack 535 is moved away from the push-pull driving assembly 42 by the meshing transmission of the second clutch gear 534 and the clutch output rack 535, so that the first elastic element 536 is compressed. Meanwhile, the push-pull output member 422 is driven to rotate by the rotation of the push-pull driving motor 421, and when the push-pull output member 422 rotates to a certain position, the push-pull output member 422 is positioned at a position engaged with the push-pull member 41. The sliding box 51 slides under the elastic force of the first elastic element 536 and the driving of the clutch driving motor 531, and drives the push-pull output member 422 to engage with the push-pull member 41. The clutch driving motor 531 continues to rotate, the sliding box 51 does not slide, the clutch output rack 535 moves in a direction away from the push-pull driving assembly 42, the first elastic member 536 continues to compress, and the clutch driving motor 531 stops rotating when the clutch output rack 535 is located at the set position with respect to the fixed housing 1.

To control the operation of the push-pull driving assembly 42 and the push-pull clutch mechanism 5, the push-pull mechanism provided in this embodiment further includes a first limiting assembly 61 and a second limiting assembly 62. The first limiting assembly 61 comprises a first limiting block 611 and a first limiting switch 612, the first limiting block 611 is arranged at one end of the clutch output rack 535, which is connected with the first elastic element 536, a main control board 55 is arranged between the sliding box body 51 and the cover body 56, the main control board 55 is fixedly connected with the sliding box body 51, and the first limiting switch 612 is arranged on the main control board 55. When the clutch output rack 535 moves relative to the fixed box 52 in a direction away from the push-pull drive assembly 42, the first limit switch 612 can be triggered by the first limit block 611.

The second limiting assembly 62 includes a second limiting block 621 and a second limiting switch 622, the second limiting block 621 is disposed on the fixed box 52 and is located at one end of the clutch output rack 535 away from the first elastic element 536, the second limiting switch 622 is disposed on the main control board 55, and when the sliding box 51 moves from the first position to the second position relative to the fixed box 52, the second limiting switch 622 can be triggered by the second limiting block 621.

When the rotation driving motor 71 drives the rotation driving set 72 to rotate and the door 2 and the housing 1 do not rotate, the angle sensor 74 will have a detection error, which is not beneficial to control the rotation mechanism 7.

To solve the above problem, fig. 13 is a schematic view of the structure of the moment arm pin in the mated state with the door body 2, and as shown in fig. 13, the door body 2 includes an inner cover 26 and an outer cover, the door hinge shaft 21 is connected with the inner cover 26, and the door hinge shaft 21 is at least partially located inside the door body 2.
