[0068] Please refer to Figures 1 to 5As shown, the present application provides an electrically controlled clutch structure of an actuating device, wherein the actuating device 8 mainly comprises a gear box 81, an electric motor 82, a speed reduction mechanism 83, a transmission mechanism 84, the electrically controlled clutch structure 1 and other related components or devices.

[0069] The gear box 81 mainly comprises a seat body 811 and a cover body 815 corresponding to the cover of the seat body 811, the speed reduction mechanism 83 is arranged on the seat body 811 and comprises a plurality of spur gears with different sizes, the electric motor 82 and the transmission mechanism 84 are mounted on the seat body 811 and are connected and driven by the speed reduction mechanism 83, and the transmission mechanism 84 has a push rod 841 and related components. Since the above-mentioned components or mechanisms are prior art, they will not be described in detail.

[0070] The electrically controlled clutch structure 1 of the present application is arranged in the gear box 81 and corresponds to the electric motor 82, and mainly comprises a driver 10, a cam 20, a clutch wheel 30 and a transmission wheel 40.

[0071] The driver 10 mainly comprises a motor body 11, a bracket 12 and a plurality of screwing components 13. The seat body 811 is internally provided with a plurality of threaded studs 812, the electric motor 82 has a rotating shaft 821, the bracket 12 is locked to the threaded studs 812 of the seat body 811 by the screwing components 13, the motor body 11 is accommodated and fixed in the bracket 12 and is formed on the side of the rotating shaft 821.

[0072] The cam 20 is connected to the motor body 11 and is driven to rotate by the motor body 11. The cam 20 has a curved profile on its upper end surface, and mainly comprises a first actuating part 21, a second actuating part 22 and two inclined surfaces 23. The first actuating part 21 and the second actuating part 22 are oppositely arranged and have a height difference therebetween, and each inclined surface 23 is connected between the first actuating part 21 and the second actuating part 22. A trigger body 24 is protruded on the lower end surface of the cam 20.

[0073] The clutch wheel 30 mainly comprises a disc body 31 and a column body 32 extending from the disc body 31. The disc body 31 and the column body 32 are provided with a positioning hole 33 at the center thereof. A plurality of fitting blocks 34 are arranged on the end surface of the disc body 31 away from the column body 32. Part of the disc body 31 is arranged on the curved profile of the cam 20, and the cam 20 is operable to actuate the disc body 31 of the clutch wheel 30. The rotating shaft 821 has a positioning plane 822, and the clutch wheel 30 is sleeved on the positioning plane 822 of the rotating shaft 821 through the positioning hole 33, so that the clutch wheel 30 is driven to rotate by the rotating shaft 821.

[0074] The transmission wheel 40 is movably connected to the rotation shaft 821 and formed below the clutch wheel 30, and is engaged with the gear of the speed reduction mechanism 83 for transmission. The transmission wheel 40 is provided with a plurality of engaging grooves 41 corresponding to the positions of the engaging blocks 34 of the clutch wheel 30, so as to be engaged or disengaged with each other. The so-called "movably connected" means that the transmission wheel 40 can rotate freely (or idle) relative to the rotation shaft 821 when the transmission wheel 40 is disengaged from the clutch wheel 30, and the rotation shaft 821 and the clutch wheel 30 are fixed.

[0075] In an embodiment, the electrically controlled clutch structure 1 further comprises a signal detector 50 arranged inside the gear box 81 and corresponding to the trigger body 24 of the cam 20. The signal detector 50 mainly comprises a first detection unit 51 and a second detection unit 52. The first detection unit 51 is triggered by the trigger body 24 when the clutch wheel 30 and the transmission wheel 40 are disengaged, and the second detection unit 52 is triggered by the trigger body 24 when the clutch wheel 30 and the transmission wheel 40 are engaged.

[0076] In an embodiment, the electrically controlled clutch structure 1 further comprises a processor 60, and the driver 10, the signal detector 50 and the motor 82 are electrically connected to the processor 60.

[0077] In an embodiment, the electrically controlled clutch structure 1 further comprises a reset spring 35. The rotation shaft 821 comprises a first retaining ring 823 and a washer 824. The first retaining ring 823 is embedded in the rotation shaft 821 and stops the washer 824. The reset spring 35 is sleeved on the outer periphery of the column body 32 of the clutch wheel 30 and is elastically clamped between the disc body 31 and the washer 824.

[0078] In an embodiment, the electrically controlled clutch structure 1 further comprises two wear-resistant washers 36. The rotation shaft 821 further comprises a second retaining ring 825 and a stop ring 826. The second retaining ring 825 is embedded in the rotation shaft 821. Each wear-resistant washer 36 is sleeved on the rotation shaft 821. One wear-resistant washer 36 is arranged between the stop ring 826 and the transmission wheel 40, and the other wear-resistant washer 36 is arranged between the transmission wheel 40 and the second retaining ring 825.

[0079] In an embodiment, the electrically controlled clutch structure 1 further comprises a force detector 70 arranged on the transmission mechanism 84 for detecting whether the push rod 841 bears a load or a force.

[0080] Please continue to refer to Figures 6 to 9As shown, when the push rod 841 of the transmission mechanism 84 is extended to the upper limit position, the user outputs a control signal by pressing the button (not shown), and the processor 60 controls the driver 10 to operate, and the motor body 11 of the driver 10 drives the cam 20 to rotate. At this time, the disc body 31 of the clutch 30 is lifted by the first actuator 21 of the cam 20, so that the clutch 30 moves upward to disengage from the transmission wheel 40 (each engagement block 34 and each engagement groove 41 are disengaged, i.e. in a disengaged state). At this time, the rotating shaft 821 remains stationary, and the transmission wheel 40 rotates relative to the rotating shaft 821. At the same time, the trigger body 24 of the cam 20 rotates to the first detection unit 51 position, and transmits a signal to the processor 60. After receiving the signal that the clutch 30 is disengaged from the transmission wheel 40, the processor 60 controls the motor 82 to stop operating. At this time, the push rod 841 can easily move under the action of an external force, i.e. when the actuator 8 is applied to the lawn mower, the lawn mower can quickly adjust the height of the cutter according to the height of the ground, so as to reduce the area of the grass that is not cut.

[0081] After the push rod 841 moves, the user can press the button again to output a control signal, and the processor 60 controls the driver 10 to operate, and the motor body 11 of the driver 10 drives the cam 20 to rotate in the opposite direction. At this time, the disc body 31 of the clutch 30 is located in the second actuator 22 of the cam 20, and the elastic force of the reset spring 35 makes the clutch 30 move downward, and the engagement block 34 of the clutch 30 and the engagement groove 41 of the transmission wheel 40 are engaged with each other (i.e. in an engaged state). The clutch 30 can drive the transmission wheel 40 to rotate. At the same time, when the trigger body 24 of the cam 20 rotates to the second detection unit 52 position, the second detection unit 52 transmits a signal to the processor 60 that the engagement block 34 of the clutch 30 and the engagement groove 41 of the transmission wheel 40 are engaged. The processor 60 controls the motor 82 to resume operation, and at this time the push rod 841 can be normally extended or retracted.

[0082] The above description is only a preferred embodiment of the present application, and is not intended to limit the scope of the patent. Other equivalent changes made in accordance with the spirit of the present application should also be included in the scope of the patent.
