Gap.There can be gap between speculum cover board 5 and protective cover plate 3, can also fit closely.When normal use, dust can be fallen
On the minute surface of speculum 4, when extraneous wind-force is larger or have vehicle by when, the air outside mirror assembly can blow to
In mirror assembly, and wind groove 51 was blowed to, the dust on mirror mirror can be carried away during air flows,
Dust is with the wind by crossing gap, speculum cover board and speculum cover board branch between wind groove 51, speculum cover board and tubular pedestal
Gap between pushing out ring platform flows in the inner cavity of tubular pedestal 1, and dust is fallen in tubular pedestal 1, and air can be by crossing in air holes
Discharge, realizes the automated cleaning to speculum.Moreover, when there is ponding on mirror mirror, when external air blows to instead
When penetrating mirror assembly, high pressure draught can be formed on mirror mirror, ponding is blowed in rhone, avoids mirror mirror
Ponding.
In the present embodiment, the corresponding end-faces of mistake wind groove and protective cover plate on speculum cover board are encircled into lateral air duct.Its
In his embodiment, lateral air duct can be formed between speculum cover board and speculum mounting base with arranged for interval.Alternatively, in speculum
Lateral air duct is respectively provided between cover board and speculum mounting base and between speculum cover board and protective cover plate.Alternatively, at other
In embodiment, speculum cover board can be cancelled, speculum mounting base is made to be arranged separately in tubular pedestal.
In the present embodiment, the first via and the second via constitute exhaust outlet, and the inner cavity of tubular pedestal constitutes pedestal and draws
Wind section, speculum cover board and speculum cover plate support land in the up-down direction arranged for interval and to be formed between the two laterally
Air inducing section, arranged for interval between speculum cover board and the inner wall of tubular pedestal and form annular air inducing section.Annular air inducing section, cross
It is connected to air inducing section with pedestal air inducing Duan Jun, together constitutes air-inducing passage.Air-inducing passage and lateral air duct together constitute
Air channel structure.
