Embodiment 1

[0039] See figure 1 , Automatic anti-glare inner rearview mirror, including a support 11, the support 11 is fixed on the center of the windshield of the car, a ball head 14 is provided on the support 11, a center hole is opened on the ball head 12, and the support 11 A cavity is also provided inside to facilitate the passage of the wire 12. A concave ball hole 15 is provided in the center of the back of the rotating plate 10, and the ball head 14 of the support 11 is installed in the concave ball hole 15 in the center of the center of the back of the rotating plate 10; the rotating plate 10 is installed on the support 11. In other words, there is a relatively large friction force between the concave ball hole 15 and the ball head 14, that is, the rotating plate 10 needs to apply a relatively large torque to make the rotating plate 10 rotate around the ball head 14, so that the driver After adjusting the position of the inner rear-view mirror, the inner rear-view mirror will not...

Embodiment 2

[0048] See Figure 5 The automatic anti-glare inner rearview mirror of this embodiment is the same as that of Embodiment 1 except that the transmission mechanism is different from that of Embodiment 1. The transmission mechanism of this embodiment includes a rotating sleeve 20 arranged at the bottom of the rotating plate 10 The worm 21 and the worm wheel 22 arranged on the output shaft of the DC motor 3; the worm 21 meshes with the worm wheel 22. When the DC motor 3 is working, the worm wheel 22 and the worm 21 drive the mirror housing 9 to flip relative to the rotating plate 10, In turn, the lens ring 8 drives the anti-glare lens 7 to turn over.

Embodiment 3

[0050] See Image 6 with Figure 7 The automatic anti-glare inner rearview mirror of this embodiment is the same as the first embodiment except that the transmission mechanism is different from that of the first embodiment. The transmission mechanism of this embodiment includes a worm gear transmission mechanism, a large gear 23, and an adjusting rod 24. The worm 25 in the worm gear transmission mechanism is provided on the output shaft of the DC motor 3, and the worm wheel 26 and the large gear 23 are provided on the shaft On the mirror housing 9, the worm 25 meshes with the worm wheel 26, and the worm wheel 26 meshes with the large gear 23; the adjusting rod 24 axially penetrates through the rod holes 29 on the two ribs 27 and 28 in the mirror housing 9, so that there are 24 adjusting rods It can be slid in the axial direction, and the normal direction cannot act alone, and can only be flipped relative to the rotating plate 10 together with the mirror housing 9. A rack 30 mes...

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 [0001] The invention relates to a rearview mirror, in particular to an automatic anti-glare inner rearview mirror. The function of the rearview mirror is: when driving at night, when the headlights of the rear car illuminate the mirror surface of the inner rearview mirror, the mirror surface automatically flips to change its reflectivity, thereby effectively controlling the glare of the driver caused by the strong light of the rear light , So that the driver can effectively avoid eye fatigue caused by dazzling when driving at night, making driving safer. Background technique [0002] The inner rearview mirror is a kind of interior accessory commonly used in various motor vehicles, and it plays a vital role in the driving safety of the car. The anti-glare inner rearview mirror plays a more important role for safe driving. At present, the anti-glare inner rearview mirror is basically an electronic anti-glare inner rearview mirror, which can attenuate the light ref...
