The above is the basic scheme of the present embodiment. The driving motor 100 is started, the planetary gear train 300 is driven to rotate through the transmission assembly 200, the planetary gears 320 of the planetary gear train 300 revolve around the sun gear 310, and when the sun gear 310 is not limited, the planetary gears 320 drive the sun gear 310 to idle;

the mechanical clutch assembly 400 is started to limit and stop rotation of the sun gear 310, the sun gear 310 cannot rotate, the planet gears 320 drive the winder 510 to rotate, and the linear traction unit is driven, so that traction of the sliding door is realized.

When the mechanical clutch assembly 400 acts on the sun gear 310, the clutch teeth 311 on the sun gear 310 and the limit buckles 410 limit, so that the sun gear 310 cannot rotate relative to the limit buckles 410, and rotation stopping is achieved.

Specifically, referring to fig. 1, the planetary gear system 300 is a planetary gear 320 structure in the prior art, and the transmission manner is the same as that in the prior art, and the number of planetary gears 320 is a plurality.

Compared with an electromagnetic clutch, the mechanical clutch is adopted in the embodiment, so that the power consumption in use is reduced; meanwhile, in the arrangement of the embodiment, the operating shifting rod can be reserved for driving the clutch device during installation, and the clutch can be switched to a manual mode through the shifting rod under the condition of power failure, so that the clutch device has a manual operation space and is more operative.

The specific implementation of the mechanical clutch assembly 400 in this embodiment is: a sliding limiting block 420 is arranged on the limiting buckle 410, and a clutch groove is arranged on one side, facing the clutch teeth 311, of the sliding limiting block 420;

in this embodiment, the driving motor 100, the transmission assembly 200 and the planetary gear train 300 are all located in the housing 600, the stop button 410 of the mechanical clutch assembly 400 is located outside the housing 600, and is connected with the sliding stop block 420 inside the housing 600 through the through hole 601 on the housing 600, so as to drive the sliding stop block 420.

Preferably, the through hole 601 is a straight groove provided in a radial direction, and limits movement of the slide stopper 420 so that the slide stopper 420 can slide only in the radial direction.

In order to convert the rotation motion of the limit button 410 into the linear motion of the sliding limit button 420, in this embodiment, a guiding slot 411 is provided on the limit button 410, and a guiding post 421 capable of sliding in the guiding slot 411 is provided on the sliding limit button 420;

referring to fig. 2, the two ends of the guide slot 411 are an unlocking end a and a locking end b, respectively; the notch of the locking end b is identical to the section of the guide post 421 and smaller than the notch of the unlocking end a.

Preferably, the radial dimension of unlocking end a is greater and the radial dimension of locking end b is smaller, while locking end b is closer to the center of sun gear 310.

The guide post 421 is inserted into the guide slot 411 through the through hole 601 on the housing 600, when the limit button 410 rotates, the position of the guide post 421 in the guide slot 411 changes, the guide slot 411 rotates clockwise along with the limit button 410, and the position of the guide post 421 in the guide slot 411 moves from the unlocking end a to the locking end b;

in the separated state of the mechanical clutch assembly 400, the guide post 421 is located at the unlocking end a of the guide slot 411; as the guide slot 411 rotates, the guide post 421 moves to the locking end b, and the distance from the central axis of the sun gear 310 decreases with the position of the guide slot 411, so that the sliding stopper 420 gradually approaches the clutch teeth 311 on the sun gear 310.

In this embodiment, the mechanical clutch assembly 400 further includes a clutch driving component 430, and the clutch driving component 430 drives the limit button 410 to rotate, so that the guide slot 411 rotates to drive the sliding limit block 420.

Referring to fig. 2, in the present embodiment, a movable slot 431 is formed on a driving shaft of the driving motor 100, one end of the limit button 410 is provided with a pushing rod 412, and the pushing rod 412 is clamped into the movable slot 431;

when the driving shaft extends out, the groove wall of the movable groove 431 pushes the pushing rod 412 outwards, so that the limit button 410 is driven to rotate clockwise; when the driving shaft is retracted, the other side groove wall of the movable groove 431 is propped against the pushing rod 412, and the pushing rod 412 is pulled back, so that the limit button 410 rotates anticlockwise.

After the door is opened, the clutch driving part 430 drives the limit button 410 to rotate, when the limit button 410 rotates, the guide post 421 on the sliding limit block 420 moves from the locking end b to the unlocking end a in the guide slot 411, so that the clutch slot is separated from the clutch teeth 311 in order to make the sliding limit block 420 move outwards, in this embodiment, the mechanical clutch assembly 400 further includes a reset elastic piece 440, and the reset elastic piece 440 pushes the sliding limit block 420 to push the sliding limit block 420 outwards.

Specifically, referring to fig. 2, a sliding groove 602 is provided on the upper end surface of the housing, the through hole 601 is located in the sliding groove 602, and the through hole 601 is located at the bottom of the sliding groove 602; a sliding vane 450 is arranged in the sliding groove 602, and a guide post 421 passes through the sliding vane 450; slide 450 is limited to slide in slide groove 602; the reset spring 440 is propped against the inner groove wall of the sliding vane 450 and the sliding groove 602;

when the clutch driving part 430 pulls back the limit button 410, and the limit button 410 moves to the unlocking end a of the guide slot 411 during the rotation process, the elasticity of the reset spring 440 pushes the sliding vane 450 outwards, and drives the sliding limiting block 420 to move outwards in the radial direction, so that the clutch slot is separated from the clutch teeth 311, and the separation of the mechanical clutch assembly 400 is completed.

When the mechanical clutch assembly 400 is not in operation, that is, the clutch teeth 311 and the clutch slot are in a separated state, at this time, the guide post 421 is positioned at the unlocking end a of the guide slot 411, and the slide 450 is ejected to the outer portion of the slide slot 602 by the reset spring 440, as shown in fig. 4;

then, since the sliding vane 450 and the sliding limiting block 420 are a moving unit, the sliding limiting block is also located at an outer position, and the clutch groove is separated from the clutch teeth 311 on the sun gear 310, as shown in fig. 5;
