[0026] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0027] Embodiment 1: An electronic rearview mirror for an automobile. Refer to Figures 1 to 4 , a mirror body 11 is fixedly embedded and installed inside the side of the installation frame body 1, a transmission plate 2 is slidably installed on the side of the installation frame body 1, a hollow storage frame 21 is fixedly installed on the surface of the side of the transmission plate 2 close to the mirror body 11, a movable plate 22 is slidably inserted into the inner side of the hollow storage frame 21, first cleaning cushions 26 are fixedly installed on the surfaces of both ends of the side of the hollow storage frame 21 close to the mirror body 11, a second cleaning cushion 27 is fixedly installed on the surface of the side of the movable plate 22 close to the mirror body 11, and the sides of the first cleaning cushion 26 and the second cleaning cushion 27 are slidably attached to the outer surface of the mirror body 11. A push plate 23 is fixedly installed on the side surface of the movable plate 22, guide blocks 24 are fixedly installed on the surfaces of both ends of the side of the push plate 23, guide grooves 25 are formed at both ends of the inner side of the hollow storage frame 21, and the guide blocks 24 are slidably inserted into the guide grooves 25. A push spring 28 is movably installed on the inner side of the hollow storage frame 21, and the two ends of the side of the push spring 28 are respectively movably attached to the push plate 23 and the inner wall of the hollow storage frame 21. By slidably inserting the movable plate 22 into the hollow storage frame 21, and respectively providing the first cleaning cushion 26 and the second cleaning cushion 27 at the bottoms of the hollow storage frame 21 and the movable plate 22, and combined with the reverse pushing action of the push spring 28, the cleaning area of the movable plate 22 and the hollow storage frame 21 can be adjusted adaptively, so that the first cleaning cushion 26 and the second cleaning cushion 27 can always wipe and clean the surface of the mirror body 11, improving the cleaning quality of the surface of the mirror body 11 and avoiding affecting driving safety.

[0028] Specifically, refer to Figures 1 to 4 , a transmission frame 4 is fixedly installed on the bottom surface of the installation frame, a rotating lead screw 41 is rotatably installed inside the transmission frame 4 through a bearing, a transmission sleeve 42 is movably sleeved on the outer surface of the rotating lead screw 41 through a thread, a connecting rod 43 is fixedly installed on the outer side of the transmission sleeve 42, and the connecting rod 43 penetrates and is slidably inserted into the inner side of the side of the transmission frame 4. By the rotational transmission action of the rotating lead screw 41 on the transmission sleeve 42, the transmission plate 2 can be driven to automatically move horizontally in front of the installation frame body 1.

[0029] Furthermore, refer to Figures 1 to 4, a connecting plate 45 is fixedly installed on the bottom surface of the transmission plate 2. The connecting plate 45 is slidably arranged outside the transmission frame 4, and the side of the connecting plate 45 is fixedly connected to the top of the connecting rod 43. The rationality of the transmission of the entire mechanism is ensured by the connection of the connecting plate 45 and the connecting rod 43.

[0030] It should be noted that, referring to Figures 1 to 4 , a sliding rod 3 is fixedly installed on the top surface of one side of the movable plate 22 away from the hollow storage frame 21. Sliding grooves 31 are formed on both sides of the transmission plate 2 away from the hollow storage frame 21, and the sliding rod 3 is slidably inserted into the sliding grooves 31. Under the guiding and sliding action of the sliding grooves 31 on the sliding rod 3, when the movable plate 22 is pushed by the pushing spring 28, the movable plate 22 can only move vertically without tilting, which affects the wiping and cleaning quality of the surface of the mirror body 11.

[0031] It should be noted that, referring to Figures 1 to 4 , movable rods 32 are fixedly installed on both ends of the side surface of the transmission plate 2. Activity grooves 33 are formed inside both ends of the side of the installation frame body 1, and the movable rods 32 are slidably inserted into the activity grooves 33. Under the guiding and sliding action of the activity grooves 33 on the movable rods 32, when the transmission plate 2 is driven by the rotation of the lead screw 41, the transmission plate 2 can only move horizontally back and forth on the side of the installation frame body 1.

[0032] It is worth introducing that, referring to Figures 1 to 4 , a limiting groove 5 is formed in the middle of the side of the transmission frame 4, and the connecting rod 43 is inserted through and slidably inserted into the limiting groove 5. A servo motor 44 is fixedly installed on the outer surface of the transmission frame 4, and the side of the transmission shaft of the servo motor 44 is fixedly connected to the outside of the lead screw 41 through a coupling. Through the structural action of the servo motor 44, the clockwise and counterclockwise rotations of the lead screw 41 can be transmitted by controlling its forward and reverse rotations, ensuring that the transmission plate 2 can automatically move horizontally back and forth to fully wipe and clean the surface of the mirror body 11.

[0033] During operation, while driving, when the driver needs to observe the road conditions behind the vehicle using the mirror body 11 inside the mounting frame 1 and finds that the cleanliness of the surface of the mirror body 11 is insufficient and affects the observation quality, the servo motor 44 is turned on through an external control switch, and its operation drives the rotating lead screw 41 to rotate synchronously in a reciprocating manner clockwise and counterclockwise inside the transmission frame 4. Subsequently, with the rotational transmission of the rotating lead screw 41 to the transmission sleeve 42 and the guiding and limiting effect of the limiting groove 5 on the connecting rod 43, the transmission sleeve 42 can move horizontally and reciprocally left and right inside the transmission frame 4. Furthermore, through the synchronous transmission of the connecting rod 43 and the connecting plate 45, the transmission plate 2 can move horizontally in front of the mounting frame 1 under the guiding and sliding effect of the movable groove 33 on the movable rod 32. Thus, the hollow storage frame 21 and the movable plate 22 can be driven to move horizontally and reciprocally left and right in front of the mirror body 11, enabling the first cleaning soft pad 26 and the second cleaning soft pad 27 to wipe and clean horizontally and reciprocally on the outside of the mirror body 11. When the movable plate 22 moves along the outside of the mirror body 11, under the abutting effect of the inner edge of the top of the mounting frame 1 and the guiding and sliding effect of the sliding groove 31 on the sliding rod 3, the movable plate 22 is abutted and moves horizontally inside the hollow storage frame 21 to adjust the overall length of the movable plate 22 and the hollow storage frame 21. When the movable plate 22 retracts into the hollow storage frame 21, the movable plate 22 abuts against the push plate 23, causing the push plate 23 to move horizontally inside the hollow storage frame 21 synchronously under the guiding and sliding effect of the guiding groove 25 on the guiding block 24. After squeezing the push spring 28 and deforming it, when the movable plate 22 reciprocates, the movable plate 22 loses the abutting effect of the mounting frame 1 on it and is pushed outward by the reverse force of the push spring 28, enabling the movable plate 22 to move out of the hollow storage frame 21 synchronously, ensuring that the cleaning area of the first cleaning soft pad 26 and the second cleaning soft pad 27 can be adjusted adaptively according to the shape of the mirror body 11, and ensuring that the bottom surfaces of the first cleaning soft pad 26 and the second cleaning soft pad 27 can fit the surface of the mirror body 11 and wipe and clean the surface of the mirror body 11 during reciprocating movement, thereby improving driving safety.
