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 5A sealing structure of a front combination lamp dimming motor includes a lower housing 1, an upper housing 2, a worm gear 14, and a second driven gear 9. A circuit board 11 is fixedly connected to the interior of the lower housing 1 and the upper housing 2. A power opening structure 3 is fixedly connected to the lower surface of the lower housing 1. The power pin on the circuit board 11 passes through the lower surface of the lower housing 1 and is located in the power opening structure 3. A T-type motor 12 is fixedly connected to the circuit board 11. The output shaft of the T-type motor 12 is fixedly connected to a worm 13. The worm gear 14 is meshed with the worm 13. A mounting shaft 7 is fixedly connected to the lower housing 1. The worm gear 14 is rotatably connected to the mounting shaft 7. A first driven gear 15 is fixedly connected to the side of the worm gear 14. The first driven gear 15 is meshed with the second driven gear 9. The second driven gear A threaded sleeve 10 is fixedly connected to the gear 9, and a dimming screw 8 is connected to the inner thread of the threaded sleeve 10. When the T-type motor 12 is energized, the T-type motor 12 rotates while driving the worm 13 to rotate, and the worm 13 drives the worm wheel 14 to rotate. Since the side of the worm wheel 14 is fixedly connected to the first driven gear 15, the first driven gear 15 is meshed with the second driven gear 9, so when the worm wheel 14 rotates, it drives the first driven gear 15 to rotate, and the first driven gear 15 will drive the second driven gear 9 to rotate. Because the second driven gear 9 is fixedly connected to the threaded sleeve 10, the threaded sleeve 10 and the dimming screw 8 are threadedly connected, when the second driven gear 9 drives the threaded sleeve 10 to rotate, it will drive the dimming screw 8 to move, and the dimming effect is achieved through the movement of the dimming screw 8.

[0022] The housing seal ring 16 is installed in the slot provided in the upper housing 2, the side of the lower housing 1 is fixedly connected to the sleeve 4, the side of the sleeve 4 is fixedly connected to the hand-adjusting wheel 6, the end of the dimming screw 8 without a thread is slidably connected to the hand-adjusting wheel 6, the other end of the dimming screw 8 is slidably connected to the screw sleeve 5, and a hand-adjusting wheel seal ring 17 is installed in the sleeve 4. The side of the upper housing 2 is fixedly connected to the screw sleeve 5, and a front end seal ring 18 is installed at the bottom of the upper housing 2. The front end seal ring 18 and the screw Sleeve 5 is concentric, representing the sealing structure of a headlight dimming motor. It comprises a manual adjustment wheel seal 17, a housing seal 16, and a front end seal 18. After the manual adjustment wheel seal 17 is installed, it snaps into place in the upper housing, ensuring tightness when the manual adjustment wheel is turned. The upper housing 2 has a notch within it, which is filled with the housing seal 16. During assembly, the upper end face of the lower housing 1 presses against the housing seal 16, which is compressed and fills the notch in the upper housing, achieving a sealing effect. The front end seal is placed at the bottom of the lower housing, where it mates with the client. By snapping into the mounting hole and screwing it in, the front end seal is compressed and acts as a seal.

[0023] The functional principle of this utility model can be explained through the following operation modes:

[0024] When the T-type motor 12 is energized, the T-type motor 12 rotates while driving the worm 13 to rotate, and the worm 13 drives the worm wheel 14 to rotate. Since the side of the worm wheel 14 is fixedly connected to the first driven gear 15, the first driven gear 15 and the second driven gear 9 are meshed, so when the worm wheel 14 rotates, it drives the first driven gear 15 to rotate, and the first driven gear 15 will drive the second driven gear 9 to rotate. Because the second driven gear 9 is fixedly connected to the threaded sleeve 10, the threaded sleeve 10 and the dimming screw 8 are threadedly connected, when the second driven gear 9 drives the threaded sleeve 10 to rotate, it will drive the dimming screw 8 to move, and the dimming effect is achieved by the movement of the dimming screw 8. This is a sealing structure of a headlamp dimming motor, including a hand-adjusting wheel sealing ring 17, a housing sealing ring 16, and a front end sealing ring 18. Block, after the sealing ring is put on the hand-adjusting wheel sleeve 17, it is snapped into the corresponding position of the upper shell to ensure the sealing of the upper shell when the hand-adjusting wheel is turned. A circle of notches is provided inside the upper shell 2, and the shell sealing ring 16 is filled in the notch. During assembly, the upper end face of the lower shell 1 just presses the shell sealing ring 16, and the sealing ring is compressed to fill the notch of the upper shell to achieve a sealing effect. The front end sealing ring is placed at the bottom of the lower body, where it matches the client. It is snapped into the mounting hole and screwed in, so that the front end sealing ring is compressed to play a sealing role. The utility model forms a good sealing structure by arranging the hand-adjusting wheel sealing ring, the shell sealing ring, and the front end sealing ring, which are respectively arranged at three key positions: the hand-adjusting wheel, the junction of the upper and lower shells, and the lower shell assembly interface.

[0025] 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.
