Embodiment Construction
[0037] The specific implementation of the rainproof rearview mirror provided by the embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0038] A kind of rainproof rearview mirror that the embodiment of the present invention provides, such as figure 1 As shown, it includes a mirror surface 01 and a mirror case 02. The front end of the mirror case 02 is an opening, and the mirror surface 01 is fixed on the front end of the mirror case 02; a hollow cavity 03 is formed between the mirror case 02 and the mirror surface 01, and the mirror surface 01 is at least on the upper end side There is a gap between the edge and the mirror housing 02; the rearview mirror also includes a rain sensor 04 fixed on the mirror housing 02, and a control unit 05 and an air outlet pump 06 located in the hollow cavity; wherein,
[0039] The rain sensor 04 is used to generate a signal for representing the amount of rain according to the r...

The invention discloses a rainproof rear view mirror which comprises a mirror surface and a mirror shell. The front end of the mirror shell is open, and the mirror surface is fixed at the front end of the mirror shell. A hollow cavity is formed between the mirror shell and the mirror surface, and a gap is formed between at least the upper end edge of the mirror surface and the mirror shell. The rainproof rear view mirror further comprises a rain sensor fixed to the mirror shell, a control unit and an air outlet pump, wherein the control unit and the air outlet pump are located in the hollow cavity. A signal representing the rainfall is generated according to rain drops which drop onto the rain sensor and then sent to the control unit, the control unit judges the rainfall and controls air pressure of air blown by the air outlet pump, under the control of the control unit, the air outlet pump blows out air through the gap between the mirror surface and the mirror shell, the blown air at least surrounds the upper end edge of the mirror surface to form a protection air curtain, and thus the dropping track of rain drops to the mirror surface is changed, and it is guaranteed that rain drops cannot drop onto the mirror surface.
Description
technical field [0001] The invention relates to the field of auto parts, in particular to a rainproof rearview mirror. Background technique [0002] During driving in rainy days, rainwater is easy to fall on the mirror surface of the rearview mirror. When there is a lot of rainwater, the driver cannot observe the situation behind through the rearview mirror, and there is a driving danger. In order to solve the above problems, there are two commonly used rainproof methods for rearview mirrors. The first is to increase the air flow on the mirror surface of the rearview mirror to blow away the rainwater on the mirror surface and promote the evaporation of rainwater at the same time; the second is to use The physical device cleans the rainwater on the mirror surface and heats the mirror surface to promote the evaporation of rainwater. [0003] But above-mentioned rearview mirror all is after rainwater wets mirror surface, and just mirror surface is cleaned, and wherein, when ad...
