However, in rainy or humid environments, the lens of the exterior rearview mirror is often covered by rainwater, resulting in the driver being unable to clearly observe the road conditions behind, which brings relatively large potential safety hazards to driving.

[0003] The applicant found through retrieval that the Chinese patent discloses "an automotive exterior rearview mirror with an automatic cleaning function", and its publication number is "CN 212890116 U". This patent mainly sets air holes and fan blades. When the vehicle is driving, the wind generated by driving blows into the air holes, and the fan blades in the air holes will rotate with the wind. The rotating fan blades drive the bevel gear set and the pulley set through the rotating shaft to drive the reciprocating lead screw to rotate, and the cleaning brush arranged at the bottom of the reciprocating lead screw will reciprocate back and forth along the surface of the lens, so as to automatically clean the lens of the exterior rearview mirror by using wind energy. However, this patent cannot drive the rotating shaft to rotate through the rotation of the fan blades when the vehicle is driving slowly, and it is difficult to achieve the effect of cleaning the lens, which has limitations. Therefore, we propose an automotive exterior rearview mirror with a water removal function. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1:

[0022] Please refer to the attached Figure 1 -attached Figure 4, An automotive exterior rearview mirror with a water removal function, comprising a housing 1 and a rotating assembly 2. The rotating assembly 2 includes a motor 21. The motor 21 is fixedly installed with a driven bevel gear 24 through a first rotating rod 22. An active bevel gear 25 is meshed and connected to the outside of the driven bevel gear 24. The active bevel gear 25 is fixedly installed with a first pulley 27 through a second rotating rod 26. The first pulley 27 is connected to a second pulley 28 through a belt 29. The inner wall of the second pulley 28 is fixedly installed with a threaded rod 291. The threaded rod 291 is installed with a rubber wiper blade 293 through a slider 292. The inner wall of the housing 1 is fixedly installed with a frame 4. The inner wall of the frame 4 is fixedly installed with a mirror surface 5. A heating sheet is fixedly installed at the bottom of the mirror surface 5. An installation groove is formed at the top of the housing 1, and the bottom of the motor 21 is fixedly connected to the inner wall of the installation groove. The output end of the motor 21 is fixedly connected to one end of the first rotating rod 22. The circumferential surface of the first rotating rod 22 is fixedly connected to the inner wall of the driven bevel gear 24. The side of the active bevel gear 25 away from the driven bevel gear 24 is fixedly connected to the right side of the second rotating rod 26. The left side of the second rotating rod 26 is fixedly connected to the inner wall of the first pulley 27. The circumferential surface of the first pulley 27 is connected to the inner wall of the belt 29. The inner wall of the side of the belt 29 away from the first pulley 27 is fixedly connected to the second pulley 28. The circumferential surface of the threaded rod 291 is threadedly connected to the inner wall of the slider 292. The left side of the slider 292 is fixedly installed with a rubber wiper blade 293.

[0023] A chute is formed on the inner wall of the frame 4. The outer surface of the rubber wiper blade 293 slides through the inner wall of the chute. When the rubber wiper blade 293 is not needed, the rubber wiper blade 293 can be moved to the left side of the frame 4 and be in contact with the inner wall of the frame 4, preventing the rubber wiper blade 293 from blocking the mirror surface 5, enabling the driver to maintain a clear vision in normal weather and when water removal is not required, and not affecting the observation of the rear road conditions due to the presence of the rubber wiper blade 293. A heating sheet is installed at the bottom of the mirror surface 5, which can quickly increase the temperature of the mirror surface 5 and accelerate the evaporation of water vapor, effectively preventing the condensation of water vapor on the mirror surface 5.

[0024] Specifically, the motor 21 drives the first rotating rod 22 to rotate, causing the driven bevel gear 24 and the active bevel gear 25 to mesh, providing power for the rotating assembly 2. The cooperation among the active bevel gear 25, the first pulley 27, the belt 29, and the second pulley 28 can adjust the transmission speed according to actual needs, thereby controlling the movement speed and amplitude of the rubber wiper blade 293. At the same time, it drives the threaded rod 291 to rotate, causing the slider 292 and the rubber wiper blade 293 to move to scrape the rainwater on the mirror surface 5, ensuring the accuracy and efficiency of the water removal action. This assembly is not interfered by external environmental factors and can work continuously and stably in any environment, making the water removal function of the automotive exterior rearview mirror have good reliability and durability.

[0025] Embodiment Two:

[0026] Please refer to the attached Figure 1 and the attached Figure 5 , and on the basis of Embodiment 1, it is further obtained that a groove is provided at the top of the housing 1, and an air jet assembly 3 is fixedly installed at the top of the housing 1.

[0027] The cylinder 31 provides power for air jet, can generate a strong air flow, and the spherical joint 32 enables the nozzle 34 to rotate at multiple angles to adapt to different rain distributions and wind speeds, so as to more comprehensively and effectively remove the rain on the mirror surface 5 and ensure that the driver has a clear vision.

[0028] Specifically, by installing the spherical joint 32 at the connection between the cylinder 31 and the pipe 33, the jet direction can be flexibly adjusted. At the same time, the cylinder 31 provides air flow for the nozzle 34, so that the air flow can be accurately jetted to the area that needs to be cleaned, and the solid dirt such as dust and soil on the mirror surface 5 is blown away by the jet. In the case of more rain, the air jet assembly 3 can assist the rubber wiper blade 293 in water removal work and improve the water removal efficiency.

[0029] The working principle of this utility model: This utility model is an automotive exterior rearview mirror with a water removal function. In the rotating assembly 2, starting the motor 21 drives the first rotating rod 22 to rotate, so that the driven bevel gear 24 and the driving bevel gear 25 are engaged, thereby driving the first pulley 27, the belt 29 and the second pulley 28 on the second rotating rod 26 to rotate, so that the threaded rod 291 on the inner wall of the second pulley 28 rotates. Since the threaded rod 291 is threadedly connected to the slider 292, the slider 292 moves horizontally under the rotation of the threaded rod 291, thereby driving the rubber wiper blade 293 to move on the mirror surface 5 to scrape off the rain.
