[0033] Embodiment 2, Embodiment 2 is different from Embodiment 1 in that:

[0034] An automatic water removal and cleaning method for a rearview mirror assembly comprises: an outer shell 10, a mirror shell 11 is installed inside the outer shell 10, a heater 12 is installed on the mirror shell 11, a lens 13 is installed on the mirror shell 11, a movable guide structure is installed inside the outer shell 10, a plurality of wipers 22 are installed inside the mirror shell 11, a plurality of water outlet holes 24 are opened outside the mirror shell 11, a liquid inlet pipe 23 is installed inside the mirror shell 11, and a rain sensor 40 is installed outside the outer shell 10.

[0035] Specifically, the heater 12 is a heating wire, and the heater 12 is installed below the lens 13 . There are multiple heaters 12 .

[0036] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: in the present invention, the mirror housing 11 is carried by the housing 10, and the lens 13 is carried by the mirror housing 11. When the vehicle speed is lower than 40 miles, the rain sensor 40 identifies the rain and sends a signal. The rain sensor 40 controls the vehicle system to transport the glass water to the liquid inlet pipe 23, and the liquid inlet pipe 23 transports the glass water to the mirror housing 11, and sprays the glass water through the water outlet 24 to wash the lens 13 to remove mud and foreign matter. At the same time, the wiper 22 starts to work, and automatically adjusts the frequency by connecting to the vehicle system according to the rain sensor 40; the car air conditioner is started synchronously, and the car air conditioner blows out hot air and transports it to the air inlet pipe 20, and the air inlet pipe 20 transports the hot air to the air outlet shell 21, and the air outlet shell 21 transports the gas to the lens 13, and cooperates with the heater 12 to heat and defog, the blowing structure and the heating structure are closed within the specified time through the vehicle control system, and the rain sensor 40 automatically closes after sensing that there is no water. When the vehicle speed is higher than 40 miles, the rearview mirror starts the first micro The first micro forward and reverse motor 31 is started, and the gear 32 is driven to rotate when the first micro forward and reverse motor 31 is started. The rotation of the gear 32 drives the movable plate 33 to move up and down, thereby driving the guide plate 35 to move. After the guide plate 35 moves to the specified position, the second micro forward and reverse motor 36 is started to make the guide plate 35 block the lens 13 for rain removal. When the vehicle speed is higher than 40 miles, the rainfall value detected by the rain sensor 40 reaches the water removal standard after the wind speed of the diversion is calculated by the vehicle system. The first micro forward and reverse motor 31 and the second micro forward and reverse motor 36 are started again in the rearview mirror to start the guide plate 35 to guide the wind to the lens 13 for water removal, and the heater 12 is automatically stopped. When the vehicle speed is higher than 40 miles and the rainfall is too heavy, the rain sensor 40 recognizes that the heater 12 cannot meet the water removal effect and automatically starts the first micro forward and reverse motor 31 and the second micro forward and reverse motor 36 to drive the guide plate 35 for water removal. After the water removal is completed, the guide plate 35 is reset. In summary, the rainwater is blocked and removed during high-speed operation.
