It can be understood that, referring to FIG. 1 and FIG. 2, a clutch device in a first aspect of the disclosure includes a transmission assembly 100 and a reset assembly 200, where the transmission assembly 100 includes a first connector 110 and a second connector 120, the first connector 110 is connected to the second connector 120, the first connector 110 is provided with a bump 111 on a side of the first connector 110 close to the second connector 120, the second connector 120 is provided with a groove 121 on a side of the second connector 120 close to the first connector 110, and the second connector 120 is movable in an axial direction so that the bump 111 can be clamped in or slid out of the groove 121; and the reset assembly 200 includes an elastic element 210, which is configured to drive the second connector 120 to move towards the first connector 110.

The first connector 110 is connected to the second connector 120; the second connector 120 is driven by the elastic element 210 to move towards the first connector 110 to enable the second connector 120 to move in the axial direction and enable the second connector 120 to abut against the first connector 110, so that the bump 111 can be clamped into the groove 121. In the process of driving the first connector 110 to rotate, when the torque input to the first connector 110 is less than the maximum working torque of the clutch device, the elastic element 210 can drive the second connector 120 to be tightly pressed on the first connector 110, so that the bump 111 can be stabilized in the groove 121 to enable the first connector 110 to transmit torque to the groove 121 via the bump 111, and enable the first connector 110 to drive the second connector 120 to rotate, thereby realizing the transmission of torque; and when the torque input to the first connector 110 or the second connector 120 is greater than the maximum working torque of the clutch device, the first connector 110 can drive the second connector 120 via the bump 111 to perform an axial movement in a direction away from the first connector 110, and the second connector 120 compresses the elastic element 210, so that the bump 111 can slide out of the groove 121 to make the first connector 110 separated from the second connector 120, realizing no-load rotation of the first connector 110 or the second connector 120, and avoiding overload rotation of the clutch device to prevent the overload damage and prolong the service life.

It should be noted that the first connector 110 can be connected to a driving part such as a motor, a rotary cylinder or a hydraulic motor, and the second connector 120 can be connected to a lid 310 of an induction bin. By clamping or sliding the bump into or out of the groove 121, the overload rotation of the driving part can be prevented, and the service life of the driving part can be prolonged.

The maximum working torque of the clutch device can be set according to the elastic force of the elastic element 210. The greater the elastic force of the elastic element 210, the greater the force of the second connector 120 pressed on the first connector 110, and the greater the maximum working torque of the clutch device; and the smaller the elastic force of the elastic element 210, the smaller the force of the second connector 120 pressed on the first connector 110, and the smaller the maximum working torque of the clutch device. In addition, the elastic element 210 can be an ordinary compression spring, or an elastic element such as a rubber pad.

It can be understood that, referring to FIG. 1 and FIG. 2, a plurality of grooves 121 are formed and are evenly formed at intervals along a circumferential direction of the second connector 120. By forming the plurality of grooves 121, when the first connector 110 rotates, the elastic element 210 can drive the second connector 120 to approach the first connector 110, so that the bumps 111 can be quickly clamped into the grooves 121, which reduces the idle time of the first connector 110, accelerates the connection between the first connector 110 and the second connector 120, and improves the performance of the clutch device.

In addition, the plurality of grooves 121 are evenly formed along a circumferential direction of the second connector 120, so that the mass of the second connector 120 is evenly distributed, the shaking caused when the second connector 120 rotates is reduced, and the movement stability of the second connector 120 is improved.

Specifically, referring to FIG. 1 and FIG. 2, the number of the bumps 111 is equal to the number of the grooves 121. By providing a plurality of bumps 111 with the number equal to that of the grooves 121, the mass of the first connector 110 is evenly distributed, and the shaking caused when the first connector 110 rotates is reduced, so that the first connector 110 can move stably. In addition, by providing a plurality of bumps 111, the force between a single bump 111 and a groove 121 can be reduced, the bearing capacity of the first connector 110 and the second connector 120 can be improved, and the overload failure of the bumps 111 and the grooves 121 can be prevented, thereby reducing the wear of the bumps 111, and prolonging the service life of the bumps 111 and the grooves 121.

In addition, by setting that the number of the bumps 111 is equal to the number of the grooves 121, one bump 111 can correspond to one groove 121, the plurality of bumps 111 can enter the plurality of grooves 121 respectively, and the bumps 111 and the grooves 121 can be worn evenly, so that the service life of the first connector 110 and the second connector 120 can be prolonged, and the reliability of the clutch device can be improved.

By setting the shape of the bumps 111 to be hemispherical, the contact area between the bumps 111 and the grooves 121 can be expanded, so that the friction between the bumps 111 and the grooves 121 can be increased, and the bumps 111 and the grooves 121 can be stably connected. In addition, by setting the shape of the bumps 111 to be hemispherical, the surfaces of the bumps 111 are round and smooth, so that when the bumps 111 are clamped or slide into the grooves 121, the contact area between the bumps 111 and the grooves 121 can be reduced, the wear of the bumps 111 and the grooves 121 can be reduced, stress concentration can be avoided, and the service life of the first connector 110 and the second connector 120 can be prolonged. The grooves 121 may be of hemispherical shapes.

By providing the rotating shaft portion 113, the second connector 120 can be positioned on the first connector 110, so that the second connector 120 can slide smoothly on the first connector 110.

Specifically, referring to FIG. 1 and FIG. 2, the reset assembly 200 further includes a connecting piece 230, which is arranged around the rotating shaft portion 113, and both sides of the connecting piece 230 abut against the elastic element 210 and the clamping block 220 respectively. One end of the connecting piece 230 abuts against the elastic element 210, the other end abuts against the clamping block 220, and the connecting piece 230 is arranged around the rotating shaft portion 113, so that the connecting piece 230 can slide in the axial direction of the rotating shaft portion 113. The elastic element 210 drives the connecting piece 230 to move towards the clamping block 220, so that the connecting piece 230 abuts against the clamping block 220, thereby making the clamping block 220 uniformly stressed, preventing the clamping block 220 from falling off from the clamping slot 114, and improving the position stability of the clamping block 220.

By forming the guide strip 131 on the inner wall of the connecting cylinder 130, the second connector 120 can slide in the axial direction of the connecting cylinder 130 through the chute 122, therefore, the positioning accuracy of the second connector 120 can be improved, and the second connector 120 can slide smoothly in the axial direction of the connecting cylinder 130, facilitating the clamping or sliding of the bumps 111 into or out of the grooves 121.

When the torque input to the first connector 110 is smaller than the maximum working torque of the clutch device, the second connector 120 is driven by the elastic element 210 to move towards the first connector 110, so that the bumps 111 can be clamped into the grooves 121, the first connector 110 can drive the second connector 120 to rotate, and the second connector 120 can be clamped in the guide block through the chute 122 to make the guide strip 131 abut against the side wall of the chute 122, thereby driving the connecting cylinder 130 to rotate.

When the torque input to the first connector 110 or the second connector 120 is greater than the maximum working torque of the clutch device, the bumps 111 are separated from the grooves 121, and the second connector 120 slides in the length direction of the guide strip 131, so that the second connector 120 slides in the axial direction of the connecting cylinder 130 away from the first connector 110, the second connector 120 compresses the elastic element 210, and the first connector 110 is separated from the second connector 120, thereby achieving no-load rotation of the first connector 110 or the second connector 120, avoiding overload rotation of the clutch device, and improving the structural stability of the clutch device.

In addition, by making the guide strip 131 clamped in the chute 122, a rotation gap between the connecting cylinder 130 and the second connector 120 can be reduced, a synchronous rotation of the second connector 120 and the connecting cylinder 130 can be realized, and the transmission accuracy of the clutch device can be improved.
