step two, after the rainfall sensing sensor 11 senses that the rainfall on the front surface of the rearview mirror lens 3 is large and drops are formed, the stepping motor 42 is started through an in-vehicle controller, the stepping motor 42 drives the threaded driving rod 43 to rotate through the matching use of the driving fluted disc 44 and the stressed fluted disc 45, and under the action of the threads on the surface of the threaded driving rod 43, the threaded pipe 55 displaces on the surface of the threaded pipe, so that the transmission telescopic plate 54 drives the two sliding external members 51 to displace at the top and the bottom of the mirror body carrier plate 2, the sliding external members 51 drive the scraping plate 61 to slide on the front surface of the rearview mirror lens 3, and in the sliding process of the scraping plate 61, the cotton scraping strips 13 scrape the drops of rain on the front surface of the rearview mirror lens 3, and meanwhile, the heating plate 10 is still in a heating state, so that the front surface of the rearview mirror lens 3 is in a clear state;

it should be noted that the rainfall sensor 11 is electrically connected to an in-vehicle controller, the in-vehicle controller is a motor controller, and controls the on/off of the stepping motor 42, and in the actual use process, the on/off of the stepping motor 42 and the heating plate 10 are controlled according to the detection result of the rainfall on the front surface of the rearview mirror lens 3 in real time by the rainfall sensor 11, so as to reduce the power consumption of the automobile storage battery, and further achieve the environmental protection effect of energy conservation and emission reduction of the automobile;

step three, in the process that the inserting groove 12 scrapes raindrops on the front surface of the rearview mirror lens 3, the T-shaped guide block 52 slides in the inner cavity of the T-shaped sliding groove 53, so that the sliding sleeve 51 is displaced along the surface shape of the mirror body carrier plate 2, and meanwhile, the tension spring 9 is repeatedly expanded, so that the sliding sleeve 51, the transmission expansion plate 54 and the scraping plate 61 can automatically adjust the expansion length according to the vertical width of the mirror body carrier plate 2.

In summary, the following steps: the automatic defogging and dewatering mechanism of the automobile rearview mirror monitors the rainfall on the front surface of the rearview mirror 3 in real time through the arrangement of the rainfall sensing sensor 11, then defogges the front surface of the rearview mirror 3 through the heating sheet 10 when the rainfall is small, and drives the cotton scraping strip 13 to perform dewatering treatment on the front surface of the rearview mirror 3 through the matching use of the driving component 4, the displacement component 5 and the scraping component 6 when the rainfall is large, so that the aims of intelligently opening and closing, saving energy and reducing emission and effectively keeping the definition of the rearview mirror 3 can be achieved, the problems that the water mist or water drops are easily attached to the surface of the automobile rearview mirror due to weather or environmental influence in the actual use process of the existing automobile rearview mirror, a user cannot clearly view road conditions at the rear side of the automobile through the rearview mirror are solved, and the existing heating type rearview mirror is used, because the heating mirror surface needs the certain time, and evaporation efficiency is lower, lead to the user can't in time look over the vehicle side rear field of vision through the rear-view mirror, cause the problem of potential safety hazard for the navigating mate.

The technical features disclosed above are not limited to the combinations with other features disclosed, and other combinations between the technical features can be performed by those skilled in the art according to the purpose of the invention, so as to achieve the purpose of the invention.
