In addition, since the motor output shaft 21 of the drive motor 2 directly protrudes into the mounting cavity 51 and is connected to the cam 4, miniaturization of the apparatus can be achieved.

Further, as shown in fig. 3 and 5, the pulley 3 is provided with a wheel groove 32, and the first rotation restricting structure includes an outer wheel rotation restricting ridge 53 provided on an outer peripheral surface of the outer wheel 5 and a pulley rotation restricting ridge 31 provided on an inner peripheral surface of the wheel groove 32. The outer wheel 5 axially extends into the wheel groove 32 and is matched with the driving wheel rotation limiting edge 31 through the fit of the outer wheel rotation limiting edge 53, so that the outer wheel 5 and the driving wheel 3 synchronously rotate.

In this embodiment, the circumferential position of the driving wheel 3 and the outer wheel 5 is limited by the shape of the inner circumferential surface of the wheel groove 32 and the outer circumferential surface of the outer wheel 5, which facilitates assembly. In addition, since the outer race 5 is inserted into the wheel groove 32 of the drive pulley 3, the drive unit can be further miniaturized. Of course, in other embodiments, the driving wheel 3 and the outer wheel 5 can be used as the first rotation limiting structure through a key connection structure; or, the driving wheel 3 and the outer wheel 5 may be directly integrally formed without providing the first rotation limiting structure, and as the same structure, the number of equipment assembling steps can be reduced.

Further, as shown in fig. 5, the outer peripheral surface of the outer wheel 5 includes two outer wheel arc-shaped surfaces 54 arranged opposite to each other and an outer wheel plane 55 arranged between the two outer wheel arc-shaped surfaces 54, and the abutting edge of the outer wheel plane 55 and the outer wheel arc-shaped surface 54 constitutes an outer wheel rotation limiting ridge 53. The inner peripheral surface of the wheel groove 32 is in close fit with the outer peripheral surface of the outer wheel 5, that is, the inner peripheral surface of the wheel groove 32 is also provided with two arc-shaped surfaces and two flat surfaces.

The outer wheel plane 55 of the outer wheel 5 forms a flat opening structure, and power is transmitted through the engagement of the flat opening and the driving wheel 3. During processing, the cylindrical outer wheel 5 base body can be directly selected to process the outer wheel plane 55, namely, the processing of the outer peripheral surface of the outer wheel 5 is completed, and the processing is simple. Of course, in another embodiment, the outer peripheral surface of the outer wheel 5 may be a prismatic surface, the butt line between adjacent surfaces is the outer wheel rotation limiting ridge 53, and accordingly, the inner peripheral surface of the wheel groove 32 is also a prismatic surface.

Further, as shown in fig. 4, the clutch assembly 1 further includes a base plate 6. The mounting cavity 51 is of a channel-like configuration with an axial opening. The bottom plate 6 covers the notch of the mounting cavity, and the cam 4 is axially clamped and positioned by the bottom plate 6 and the bottom of the mounting cavity.

During assembly, an axial positioning structure is not required to be additionally arranged between the motor output shaft 21 and the cam 4, after the bottom plate 6 is assembled, the cam 4 is axially positioned by clamping the cam 4 through the groove bottom of the mounting cavity and the bottom plate 6, and the connecting difficulty of the cam 4 and the motor output shaft 21 can be reduced.

Further, as shown in fig. 3 to 5, a shaft connecting hole in the middle of the cam 4 is sleeved outside the motor output shaft 21. The second rotation limiting structure comprises a cam rotation limiting ridge 42 arranged on the shaft connecting hole and a shaft rotation limiting ridge 22 arranged on the outer peripheral surface of the motor output shaft 21, and the cam rotation limiting ridge 42 and the shaft rotation limiting ridge 22 are attached and matched to realize synchronous rotation of the cam 4 and the motor output shaft 21. Optionally, the shaft connecting hole is a D-shaped hole, and the motor output shaft 21 is a matched D-shaped column.

The damping fin 7 is fixed on the shell of the driving motor 2, and the damping fin 7 and the sliding block 9 are matched in a magnetic attraction mode along the axial direction. Specifically, both the damping fin 7 and the slider 9 may be magnetic members such as magnets, or one of them may be a magnetic member, and the other may be a metal member such as an iron block capable of being magnetically attracted. In this embodiment, the magnetic attraction between the slider 9 and the damping piece 7 prevents the slider 9 from moving freely in the mounting cavity 51 when not driven by the outer wheel 5 and the cam 4.

Specifically, the locating slot 61 is arranged on the axial end face, facing the installation cavity 51, of the bottom plate 6, and the damping fin 7 is sealed in the installation cavity 51, so that the bottom plate 6 does not need to have magnetic attraction performance on selected materials, and materials which do not influence the operation of the motor can be selected as required to be made.

Further, as shown in fig. 7, the damper 7 includes a main body and a projection structure 71 projecting from an outer peripheral surface of the main body in the radial direction.

Specifically, the arrangement of the protruding structure 71 enables the position of the slider 9 to be effectively controlled by means of the magnetic force between the slider 9 and the damping fins 7, regardless of whether the driving motor 2 or the driving pulley 3 is used as a power source. As shown in fig. 8, when the driving motor 2 is used as a power source, the state when the outer wheel 5 and the driving wheel 3 rotate relatively to a predetermined angle is used as an initial state, and when the cam 4 pushes the slider 9 into the limiting groove 52, the protruding structure 71 of the damping fin 7 adsorbs and positions the slider 9, so as to reduce the resistance of the cam 4 to push the slider 9 toward the limiting groove 52. As shown in fig. 9 and 10, when the driving wheel 3 is used as a power source, since the position of the protrusion 71 is not changed, in addition to the pushing force of the groove wall of the limit groove 52 in the process of pushing the slider 9 out of the limit groove 52, as shown in fig. 10, since the limit groove 52 and the protrusion 71 are staggered, the magnetic force of the damping piece 7 on the slider 9 can also provide a pulling force to pull the slider 9 out.

Of course, in other embodiments, the magnetic element magnetically engaged with the slider 9 may be disposed at other positions in the mounting cavity 51, for example, at a middle position of an axial end surface of the mounting cavity 51, so as to provide an assisting force for the movement of the slider 9 out of the limiting groove 52 when the driving wheel 3 is used as a power source.

Further, as shown in fig. 4, the slider 9 is a cylindrical structure, specifically, the axial direction of the slider 9 is parallel to the axial direction of the cam 4, and two axial end surfaces of the slider 9 respectively abut against the groove bottom of the mounting cavity 51 and the damping fin 7, so that stable placement of the slider 9 can be ensured, and meanwhile, when the slider 9 is clamped in the limiting groove 52, the slider 9 has a larger contact area with the limiting groove 52, and is not easy to disengage. Of course, in other embodiments, the sliding block 9 may have other shapes such as a sphere, a rectangular body, and the like.

Further, as shown in fig. 7 and 8, at least two, for example, two, sliders 9 are provided, and when the cam 4 is used as a driving source, any one of the sliders 9 is pushed into the limiting groove 52, so that the cam 4 can push the outer wheel 5 to rotate synchronously, and the operation efficiency of the device can be improved.

In this embodiment, two pushing protrusions 41 are provided, and are spaced by 180 °, and in other embodiments, three or five pushing protrusions 41 may be provided, or only one pushing protrusion may be provided. By providing the plurality of pushing projections 41, the pushing efficiency of the slider 9 when the cam 4 is used as the driving source can be further improved.

Further, as shown in fig. 8, the number of the pushing protrusions 41, the number of the sliding blocks 9, and the number of the limiting grooves 52 are equal, and in this embodiment, two pushing protrusions 41, two sliding blocks 9, and two limiting grooves 52 are provided. When the cam 4 is used as a driving source, each pushing boss 41 pushes each sliding block 9 into each limiting groove 52, the outer wheel 5 can be pushed by the cam 4 and different sliding blocks 9, and even if one sliding block 9 is separated from the corresponding limiting groove 52, the cam 4 can be ensured to push the outer wheel 5.

Further, as shown in fig. 2, 3 and 5, the driving assembly further includes a motor bracket 8, and the housing of the driving motor 2 is axially inserted and fixed to the motor bracket 8. The motor support 8 is inserted into the driving wheel 3 along the axial direction, and the motor support 8 is rotatably connected to the driving wheel 3 through a bearing 81.
