[0032] As Figures 1 to 3 shown, the present utility model provides an actuator. The actuator includes: a housing 1, a first gear 2, a return spring 3, a roller 4, a first stopper 5, a cam 6, and a driving member 7.

[0033] Specifically, the first gear 2 is rotatably connected inside the housing 1. The two ends of the return spring 3 are respectively connected to the housing 1 and the first gear 2, and the return spring 3 is used to drive the rotated first gear 2 to reset. The roller 4 is rotatably connected inside the housing 1, and the roller 4 is coaxially arranged with the first gear 2. The first stopper 5 is arranged on the roller 4. The cam 6 is connected to the first gear 2. The first gear 2 can drive the cam 6 to rotate. The cam 6 can abut against the first stopper 5. The driving member 7 is used to drive the first gear 2 to rotate. By driving the driving member 7 to drive the first gear 2 to drive the cam 6 to rotate, the cam 6 is enabled to drive the first stopper 5 to rotate, and then the first stopper 5 drives the roller 4 to rotate from the initial position to the full stroke position. The driving member 7 is turned off. The first gear 2 and the cam 6 are reset to the initial position under the action of the return spring 3, and the roller 4 remains at the full stroke position. Compared with the prior art, this actuator can save resources and improve the user experience.

[0034] Optionally, the roller 4 is of an annular structure. The first stopper 5 is fixedly installed on the inner ring of the roller 4. The first gear 2 and the cam 6 are coaxially and fixedly connected at intervals, and the cam 6 is located inside the inner ring of the roller 4. The cam 6 can rotate relative to the roller 4. When the cam 6 abuts against the first stopper 5, the cam 6 can drive the roller 4 to rotate.

[0035] Optionally, as Figures 1 to 5 shown, the housing 1 includes a first housing 101 and a second housing 102. The first housing 101 and the second housing 102 are detachably connected. Specifically, the first housing 101 and the second housing 102 are threadedly connected, which facilitates the assembly and disassembly of the first housing 101 and the second housing 102.

[0036] Optionally, the actuator further includes a worm 8. The driving member 7 is installed in the housing 1. The driving member 7 is in transmission connection with the worm 8, and the worm 8 is in transmission connection with the first gear 2. Specifically, the driving member 7 is installed in the first housing 101. One end of the worm 8 is connected to the output shaft of the driving member 7, and the other end of the worm 8 is rotatably connected to the first housing 101, which enables the worm 8 to rotate stably.

[0037] Optionally, the actuator further includes a bearing. The outer ring of the bearing is fixed to the first housing 101, and the inner ring of the bearing is fixedly sleeved on the outer periphery of the worm 8, which can reduce the resistance of the worm 8 to rotate and enable the worm 8 to rotate smoothly.

[0038] Optionally, the actuator further includes a second gear 9. The second gear 9 is rotatably connected to the housing 1, and the second gear 9 is simultaneously in transmission connection with the first gear 2 and the worm 8. The worm 8 drives the second gear 9 to rotate, and the second gear 9 drives the first gear 2 to rotate. Specifically, in order to adjust the rotation speed of the first gear 2, the actuator is provided with a second gear 9. The second gear 9 is rotatably connected to the first housing 101. The second gear 9 is simultaneously meshed with the first gear 2 and the worm 8. The worm 8 can drive the second gear 9 to rotate, and the second gear 9 can drive the first gear 2 to rotate. The diameter of the second gear 9 is smaller than that of the first gear 2, which can reduce the rotation speed of the first gear 2, enable the first gear 2 to rotate stably, and further ensure the stability of the actuator during operation.

[0039] Optionally, the actuator further includes a third gear 10. The third gear 10 is coaxially connected to the second gear 9, and the third gear 10 is in transmission connection with the first gear 2. Specifically, the actuator is provided with a third gear 10. The third gear 10 is fixedly connected to the second gear 9 at an interval coaxially. The third gear 10 is meshed with the first gear 2, and the second gear 9 is meshed with the worm 8. The diameter of the third gear 10 is smaller than that of the second gear 9, which can further adjust the rotation speed of the first gear 2, enable the first gear 2 to rotate more stably, and further ensure the more stable operation of the actuator. Of course, in some other embodiments, the combination number of gears is determined according to actual needs, and the diameter relationship of each gear is determined according to actual needs, which will not be elaborated here.

[0040] Optionally, the actuator further includes a positioning spring 11. Both ends of the positioning spring 11 are respectively connected to the roller 4 and the housing 1. Specifically, in order to keep the roller 4 in the full-stroke position, the actuator is provided with a positioning spring 11. One end of the positioning spring 11 is connected to the roller 4, and the other end of the positioning spring 11 is connected to the second housing 102. When the roller 4 is in the initial position, due to the external force, the positioning spring 11 is in the working state. When the roller 4 is in the full-stroke position, the positioning spring 11 is in the original state. With such a setting, when the first gear 2 and the cam 6 reverse under the action of the return spring 3, the roller 4 can remain stationary under the action of the positioning spring 11, enabling the roller 4 to be kept in the full-stroke position.

[0041] Optionally, the positioning spring 11 is a torsion spring, which can make the force direction of the roller 4 along the circumferential direction of the roller 4, enable the roller 4 to rotate smoothly, and prevent jamming.

[0042] Optionally, in order to further keep the roller 4 in the full stroke position, in this embodiment, two positioning springs 11 are provided. The two positioning springs 11 are arranged at intervals along the circumferential direction of the roller 4. Specifically, the connection line of the two positioning springs 11 passes through the center of the roller 4, which can make the forces on the roller 4 balanced and improve the stability of the roller 4. Of course, in some other embodiments, the number of the positioning springs 11 is determined according to the actual situation, which will not be elaborated here.

[0043] Optionally, in order to keep the positioning spring 11 stable and prevent the positioning spring 11 from moving, the second housing 102 is provided with a positioning groove, and the positioning spring 11 is arranged in the positioning groove, which can prevent the positioning spring 11 from moving.

[0044] Optionally, the actuator further includes a second stopper 12. The second stopper 12 is arranged on the first gear 2, and one end of the return spring 3 is connected to the second stopper 12. Specifically, the actuator is provided with the second stopper 12. The second stopper 12 is fixed to the first gear 2, and the return spring 3 is connected to the second stopper 12. With such an arrangement, the first gear 2 drives the second stopper 12 to rotate, thereby deforming the return spring 3, and the return spring 3 exerts a reverse acting force on the second stopper 12 to reset the first gear 2.

[0045] Optionally, the return spring 3 is a torsion spring, which can make the force direction of the second stopper 12 along the circumferential direction of the first gear 2, enabling the first gear 2 to rotate smoothly and preventing jamming.

[0046] Optionally, in order to keep the return spring 3 stable and prevent the return spring 3 from moving, the first gear 2 and the cam 6 are fixedly connected by a rotating shaft, and the return spring 3 is sleeved on the outer periphery of the rotating shaft, which can prevent the positioning spring 11 from moving.

[0047] Optionally, the roller 4 can be reversed to the initial position by reversing the driving member 7, which drives the worm 8, the second gear 9, the third gear 10, the first gear 2 and the cam 6 to rotate in the reverse direction, so that the cam 6 abuts against the other end of the first stopper 5, thereby driving the roller 4 to rotate to the initial position; alternatively, a pulling rope can be connected to the roller 4, and by pulling the pulling rope, overcoming the elastic force of the positioning spring 11, the roller 4 can be rotated to the initial position.
