DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] Reference Figure 1-Figure 5 A built-in dimming motor that can be manually adjusted includes an upper shell structure 1, a lower shell structure 2 and a transmission shaft 13. A PCB circuit board 4 is fixedly connected to the interior of the upper shell structure 1 and the lower shell structure 2. A motor 5 is fixedly connected to the PCB circuit board 4. A worm 7 is fixedly connected to the output end of the motor 5. The inner walls of both sides of the upper shell structure 1 and the lower shell structure 2 are rotatably connected to a rotating shaft 8. A worm gear 9 is fixedly connected to the rotating shaft 8. A first driven gear 10 is fixedly connected to the rotating shaft 8. The side of the first driven gear 10 The surface is fixedly connected to the side of the worm gear 9, the worm 7 and the worm gear 9 are meshed, a locator 11 is fixedly connected to the PCB circuit board 4, and a locator sliding rod 12 is slidably connected to the side of the locator 11. A positioning slot 14 is provided on one side surface of the upper part of the transmission shaft 13, and the locator sliding rod 12 is fixedly connected in the positioning slot 14. A first thread 15 is provided at one end of the transmission shaft 13 close to the positioning slot 14, and a second driven gear 17 is threadedly connected to the first thread 15. The first driven gear 10 and the second driven gear 17 are meshed.

[0022] When the motor 5 rotates, the output end of the motor 5 drives the worm 7 to rotate. Since the worm 7 and the worm wheel 9 are meshed, the worm wheel 9 rotates along with the rotation of the worm 7, and the first driven gear 10 also rotates. Since the first driven gear 10 and the second driven gear 17 are meshed, when the first driven gear 10 rotates, it will drive the second driven gear 17 to rotate, and the second driven gear 17 is threadedly connected to the transmission shaft 13, so when the second driven gear 17 rotates, it will drive the transmission shaft 13 to move linearly, and at the same time drive the locator sliding rod 12 to slide on the locator 11.

[0023] A power hole 3 is provided at the connection between the upper shell structure 1 and the lower shell structure 2. One end of the motor 5 is fixedly connected to a power pin 6, which is located in the power hole 3. A second thread 16 is provided at one end of the transmission shaft 13 away from the positioning slot 14. A ball head connecting rod 18 is threadedly connected to the second thread 16. The annular outer surface of the ball head connecting rod 18 is provided with a plurality of vertical stripes 19. A hand-adjustable transmission shaft 20 is slidably connected to the ball head connecting rod 18. The interior of the hand-adjustable transmission shaft 20 is provided with a plurality of slide grooves 21, a plurality of vertical stripes 19. The groove 19 is slidably connected in the slide groove 21, and the manual transmission shaft 20 is rotatably connected to the circular hole opened at the connection between the upper shell structure 1 and the lower shell structure 2. Since several vertical stripes 19 are slidably connected in the slide groove 21, when the manual transmission shaft 20 is manually rotated, the manual transmission shaft 20 will drive the ball head connecting rod 18 to rotate together. Since the ball head connecting rod 18 is threadedly connected to the second thread 16 of the transmission shaft 13, when the manual transmission shaft 20 is rotated, the ball head connecting rod 18 will move to realize the manual adjustment function. By setting a handwheel adjustment device, the ball head connecting rod 18 can be driven to rotate by rotating the manual transmission shaft 20. Since the ball head connecting rod 18 and the transmission shaft 13 are threadedly connected, the rotation of the ball head connecting rod 18 will cause the ball head connecting rod 18 to extend and retract on the transmission shaft 13.

[0024] The functional principle of this utility model can be explained through the following operation modes:

[0025] When the motor 5 rotates, the output end of the motor 5 drives the worm 7 to rotate. Since the worm 7 and the worm wheel 9 are meshed, the worm wheel 9 rotates following the rotation of the worm 7. At the same time, the first driven gear 10 also rotates. Since the first driven gear 10 is meshed with the second driven gear 17, when the first driven gear 10 rotates, it will drive the second driven gear 17 to rotate, and the second driven gear 17 is threadedly connected to the transmission shaft 13. Therefore, when the second driven gear 17 rotates, it will drive the transmission shaft 13 to move linearly, and at the same time drive the positioner sliding rod 12 to slide on the positioner 11. When the manual transmission shaft 20 is manually rotated, the manual transmission shaft 20 will drive the ball connecting rod 18 to rotate together. Since the ball connecting rod 18 is threadedly connected to the second thread 16 of the transmission shaft 13, when the manual transmission shaft 20 is rotated, the ball connecting rod 18 will move to realize the manual adjustment function. By setting the handwheel adjustment device, the ball connecting rod 18 can be driven to rotate by the rotation of the manual transmission shaft 20. Since the ball connecting rod 18 and the transmission shaft 13 are threadedly connected, the rotation of the ball connecting rod 18 will cause the ball connecting rod 18 to extend and retract on the transmission shaft 13.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
