[0021] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0022] The most critical concept of the present invention is that: through the stepper motor 6, the roller 5 and the second cleaning component 4, the second cleaning component 4 is used to clean the inner surface of the lampshade 2; through the stepper motor 6, the roller 5, the pull rope 7, the slider 8, the slide groove 9 and the first cleaning component 3, the first cleaning component 3 is used to stably clean the outer surface of the lampshade 2 for the first time; when the slider 8 slides to a position close to the through hole 10, the stepper motor 6 stops rotating, and the slider 8 is reset by the spring 12 and the baffle 11, thereby achieving the secondary cleaning of the outer surface of the lampshade 2; in addition, the limiting plates 26 arranged on both sides of the slide groove 9 play a role in limiting the spring 12 to prevent the spring 12 from deviating during the movement of the slider 8 along the length direction of the slide groove 9; the present invention automatically cleans the inside and outside surfaces of the lampshade 2, and only uses one stepper motor 6 and spring 12 to clean the inside and outside surfaces of the lampshade 2, with low energy consumption.

[0023] An automatic cleaning automobile headlamp comprises a lamp housing 1 with a bulb therein and a lampshade 2 connected to the lamp housing 1, and further comprises a first cleaning component 3, a second cleaning component 4, a roller 5, a bearing (not shown in the figure) and a stepping motor 6, wherein the bearing is connected to one side of the lamp housing 1, one end of the second cleaning component 4 is in close contact with the inner surface of the lampshade 2, one end of the roller 5 is connected to the other end of the second cleaning component 4 through the bearing, the rotating shaft of the stepping motor 6 is connected to the other end of the roller 5, a pull rope 7 is wound around the roller 5, and one end of the pull rope 7 is connected to the roller 5 Fixedly connected, the first cleaning component 3 is in close contact with the outer surface of the lampshade 2, one end of the first cleaning component 3 is detachably connected with a slider 8, a slide groove 9 is opened around the edge of the lampshade 2 on the lamp housing 1, the slider 8 is slidably connected to the slide groove 9, a through hole 10 is opened on one side of the bottom of the slide groove 9 for the other end of the pull rope 7 to pass through, the other end of the pull rope 7 is connected to one end of the slider 8, a baffle 11 is connected to the other side of the bottom of the slide groove 9, a spring 12 is connected between the baffle 11 and the other end of the slider 8, and limit plates 26 are arranged on both sides of the slide groove 9.

[0024] As can be seen from the above description, when the lampshade 2 needs to be cleaned, the stepper motor 6 connected to the other end of the roller 5 by starting the rotating shaft works, and the stepper motor 6 drives the roller 5 to rotate and reel in the pull rope 7. The rotation of the roller 5 drives the second cleaning component 4 connected to one end of the roller 5 through the bearing, so that the second cleaning component 4 rotates and contacts with the inner surface of the lampshade 2 in one direction, thereby realizing the cleaning of the inner surface of the lampshade 2 by the second cleaning component 4; at the same time, the roller 5 reels in the pull rope 7 fixedly connected to the roller 5 at one end, thereby driving the slider 8 connected to the other end of the pull rope 7 at one end to move toward the through hole 10, thereby realizing the movement of the first cleaning component 3; the slider 8 slides in the slide groove 9 opened around the edge of the lampshade 2 along the lamp housing 1, so that the slider 8 can be driven The first cleaning component 3 is driven to move along the length direction of the slide groove 9, thereby achieving the effect of driving the first cleaning component 3 to stably clean the outer surface of the lampshade 2; when the slider 8 slides to a position close to the through hole 10, the stepper motor 6 stops rotating, and under the elastic force of the spring 12 connected between the baffle 11 and the other end of the slider 8, the slider 8 is reset to achieve the effect of secondary cleaning of the outer surface of the lampshade 2; in addition, the limiting plates 26 arranged on both sides of the slide groove 9 play a role in limiting the spring 12, preventing the spring 12 from deviating during the movement of the slider 8 along the length direction of the slide groove 9; the present invention automatically cleans the interior and exterior surfaces of the lampshade 2, and only uses one stepper motor 6 and spring 12 to clean the interior and exterior surfaces of the lampshade 2, with low energy consumption.

[0025] Furthermore: a guide tube 13 is sleeved inside the spring 12, one end of the guide tube 13 is connected to the baffle 11, the other end of the guide tube 13 is connected to a support rod 27, the support rod 27 is connected to the bottom of the slide groove 9, and a guide hole 14 is opened on the slider 8 for the guide tube 13 to pass through.

[0026] From the above description, it can be known that the guide tube 13 which is sleeved inside the spring 12 can prevent the spring 12 from deviating in the process of moving along the length direction of the slide groove 9 with the slider 8, thereby further guiding the spring 12, protecting the spring 12 from damage and further guiding the slider 8; one end of the guide tube 13 is connected to the baffle 11, and the other end of the guide tube 13 is connected to the bottom of the slide groove 9 through the support rod 27, so as to fix the guide tube 13 in the slide groove 9. At the same time, the support rod 27 can prevent the spring 12 and the slider 8 from sliding out of the guide tube 13.

[0027] Further: the first cleaning component 3 includes a connecting rod 15, a cleaning sponge 16 and a water tank 17, one end of the connecting rod 15 is connected to the cleaning sponge 16, and the other end of the connecting rod 15 is connected to the water tank 17. The connecting rod 15 is provided with a water inlet 18 connecting the water tank 17 and the cleaning sponge 16. The connecting rod 15 is connected to a connecting plate 19 on the side close to the slider 8, and a connecting column 20 is connected to the slider 8. The connecting column 20 is connected to the connecting rod 15 by bolts.

[0028] From the above description, it can be seen that when cleaning is required, unscrew the bolts between the connecting column 20 and the connecting rod 15, separate the connecting plate 19 connected to the connecting rod 15 on the side close to the slider 8 from the connecting column 20 connected to the slider 8, so that the connecting rod 15 can be detachably connected to the slider 8; then, the water in the water tank 17 enters the sponge through the water inlet 18 opened on the connecting rod 15, and the water is squeezed out through the sponge and the outer surface of the lampshade 2, thereby achieving the function of cleaning the outer surface of the lampshade 2.

[0029] Furthermore, a T-shaped block 21 is arranged at one end of the cleaning sponge 16 close to the connecting rod 15 , and a sliding groove 22 for the T-shaped block 21 to slide and engage is opened at one end of the connecting rod 15 .
