Abstract
The invention relates to an automatic anti-glare inner rear-view mirror, comprising a support, a mirror shell, a mirror ring, a lens and a rotating plate mounted on a ball head of the support. The mirror shell is rotarably connected with the rotating plate and is provided with a driving motor and a control circuit module inside. The driving motor drives the mirror shell to overturn the mirror with a certain angle relative to the rotating plate through a transmission plate and further drives the lens to overturn through the mirror ring; the lens is an anti-glare lens and has a second surface with the luminous reflectivity of greater than or equal to 80% and a first surface with the luminous reflectivity of smaller than or equal to 70%. The first surface and the second surface form a bevel of 3.67 degrees; a first photosensor and a second photosensor are respectively arranged on the mirror ring and the mirror shell. When the light from the back of the vehicle irradiates the first photosensor, the control circuit module controls the driving motor so that the mirror on the mirror shell on the second surface as a reflective surface automatically turns to the first glass surface as the reflective surface through the transmission mechanism, therefore, the reflectivity is overturned from the one greater than or equal to 80% to the one smaller than or equal to 70%, thereby realizing the automatic anti-glare function.
Description
Technical field
The present invention relates to back mirror, particularly a kind of automatic anti-glare inner rear-view mirror.This back mirror effect is: in the night travel process, when back car headlight is radiated at the inside rear-view mirror minute surface, minute surface overturns automatically, change its reflectivity, thereby controlled the back light high light effectively to dazzling the eyes that the driver causes, make chaufeur when night travel, effectively avoid the eye fatigue that causes because of dazzling the eyes, make driving safer.
Background technology
Inside rear-view mirror is an annex in various self-propelled vehiclees a kind of car commonly used, and it plays crucial effects for the driving safety of automobile.The abblendbar inside rear-view mirror plays a part even more important for safety traffic.Can the abblendbar inside rear-view mirror be Electronic Dimming Inside Rearview Mirror basically at present, this Electronic Dimming Inside Rearview Mirror can diminished reflex with respect to common inside rear-view mirror light to driver's eyes.When driving a vehicle night, when the back had strong illumination on inside rear-view mirror, Electronic Dimming Inside Rearview Mirror eyeglass two ends will apply a voltage automatically, thereby made the eyeglass deepening, and diminished reflex is to the light of driver's eyes.The patent document of this electron-like anti-glare inner rear-view mirror is just like the disclosed Electronic Dimming Inside Rearview Mirror of Chinese patent notification number CN201110933Y.
Though this electron-like anti-glare inner rear-view mirror can solve the abblendbar problem, the color-changing lens complex manufacturing technology, the control circuit structure is more complicated also.
