Detailed implementation mode

[0020] The technical solutions in the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Refer to Figures 1 - 5 , a dimming motor with strong applicability, including an upper housing structure 1 and a lower housing structure 2. A PCB circuit board 5 is fixedly connected inside the upper housing structure 1 and the lower housing structure 2. A motor 6 is fixedly connected to the PCB circuit board 5. The output end of the motor 6 is fixedly connected to a first driving gear 7. A gear 8 is rotatably connected to the inner wall of the lower housing structure 2. The gear 8 meshes with the first driving gear 7. A first driven gear 9 is fixedly connected to the side of the gear 8. A potentiometer 11 is fixedly connected to the PCB circuit board 5. A potentiometer slide bar 12 is slidably connected to the potentiometer 11. A bayonet structure 13 is fixedly connected to the potentiometer slide bar 12. A sleeve tube 14 is fixedly connected to the bayonet structure 13. An external thread 16 is provided on the outer surface of one end of the sleeve tube 14 close to the bayonet structure 13. A second driven gear 10 is threadedly connected to the external thread 16. The second driven gear 10 meshes with the first driven gear 9.

[0022] When the motor 6 is started, the motor 6 drives the first driving gear 7 to rotate. Since the gear 8 meshes with the first driving gear 7, the first driving gear 7 drives the gear 8 to rotate, and the first driven gear 9 rotates together with the gear 8. Because the second driven gear 10 meshes with the first driven gear 9, the first driven gear 9 drives the second driven gear 10 to rotate. Since the second driven gear 10 is threadedly connected to the sleeve tube 14, when the second driven gear 10 rotates, it will drive the sleeve tube 14 to move, thereby driving the potentiometer slide bar 12 to slide on the potentiometer 11.

[0023] A power hole 3 is provided on the side of the upper housing structure 1. A power pin 22 is fixedly connected to the PCB circuit board 5. The power pin 22 is located within the power hole 3. When the power cord can be connected to the power pin 22 through the power hole 3. A sleeve 4 is fixedly connected to the side of the upper housing structure 1. A ball head assembly 15 is rotatably connected within the sleeve 4. One end of the ball head assembly 15 is internally threaded with the sleeve 14. Different models of ball heads can be selected through the threaded connection. A notch 17 is provided on the upper surface of the upper housing structure 1. The second driving gear 21 is rotatably connected within the notch 17. By setting the ball head and the sleeve to adopt a threaded fit, and by selecting different models of ball heads, the initial position dimension of the ball head extending out can be adjusted. Selecting different models of ball heads can meet the requirements of different sizes and interfaces of customers, so that it has wide applicability.

[0024] A bushing 18 is fixedly connected through the side of the upper housing structure 1. A rotating shaft 19 is rotatably connected within the bushing 18. A second driving gear 21 is fixedly connected to the rotating shaft 19. The second driving gear 21 meshes with the second driven gear 10. The other end of the rotating shaft 19 is fixedly connected to a handwheel 20. When the electric device cannot be used, the handwheel 20 can be manually rotated. The handwheel 20 will drive the rotating shaft 19 to rotate. The rotating shaft 19 drives the second driving gear 21 to rotate. Since the second driving gear 21 meshes with the second driven gear ⑩, the second driven gear 10 will be driven to rotate when the second driving gear 21 rotates. Since the second driven gear 10 is threadedly connected to the sleeve 14, the sleeve 14 will be driven to move when the second driven gear 10 rotates. By setting the handwheel device, the length of the ball head extending out can be manually adjusted to ensure that the length of the ball head extending out can still be adjusted when the electric device fails.

[0025] The functional principle of the present utility model can be described through the following operation modes:

[0026] When the motor 6 starts, the motor 6 drives the first driving gear 7 to rotate. Since the gear 8 meshes with the first driving gear 7, the first driving gear 7 drives the gear 8 to rotate, and the first driven gear 9 rotates together with the gear 8. Because the second driven gear 10 meshes with the first driven gear 9, the first driven gear 9 drives the second driven gear 10 to rotate. Since the second driven gear 10 is threadedly connected to the sleeve 14, when the second driven gear 10 rotates, it will drive the sleeve 14 to move, thereby driving the potentiometer slide bar 12 to slide on the potentiometer 11. When the electric device cannot be used, the hand wheel 20 can be rotated manually. The hand wheel 20 drives the rotating shaft 19 to rotate, and the rotating shaft 19 drives the second driving gear 21 to rotate. Since the second driving gear 21 meshes with the second driven gear 10, when the second driving gear 21 rotates, it will drive the second driven gear 10 to rotate. Since the second driven gear 10 is threadedly connected to the sleeve 14, when the second driven gear 10 rotates, it will drive the sleeve 14 to move. By setting that the ball head and the sleeve adopt a threaded fit, by selecting ball heads of different models, the initial position dimension of the ball head extending out can be adjusted. Selecting ball heads of different models can meet the requirements of different sizes and interfaces of customers, so that it has wide applicability. By setting the hand wheel device, the length of the ball head extending out can be adjusted manually to ensure that the length of the ball head extending out can still be adjusted when the electric device fails.
