Embodiment 1

[0039] see figure 1, the automatic anti-glare interior rearview mirror, comprising a support 11, the support 11 is fixed on the center of the car windshield, a ball head 14 is provided on the support 11, and a center hole is provided on the ball head 12, and the support 11 A cavity is also arranged inside, so that the wire 12 passes through. A concave ball hole 15 is arranged at 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 at the center of the back of the rotating plate 10; Generally speaking, there is a relatively large frictional force between the concave ball hole 15 and the ball head 14, that is to say, the rotating plate 10 needs to apply a relatively large moment to make the rotating plate 10 rotate around the ball head 14, so that the driver After the position of the interior rearview mirror is adjusted, the interior rearview mirror will not change its position due to the vibration duri...

Embodiment 2

[0048] see Figure 5 The automatic anti-glare interior 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, wherein 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, and when the DC motor 3 works, the mirror housing 9 is driven to turn over with respect to the rotating plate 10 through the worm wheel 22 and the worm 21. Then the anti-glare lens 7 is turned over by the mirror ring 8 .

Embodiment 3

[0050] see Figure 6 and Figure 7 , the automatic anti-glare interior rearview mirror of this embodiment is all the same with embodiment 1 except that the transmission mechanism is different from embodiment 1. The transmission mechanism of this embodiment comprises a worm gear mechanism, a large gear 23, and an adjustment pull rod 24. The worm screw 25 key in the worm gear mechanism is arranged on the output shaft of the DC motor 3, and the worm wheel 26 and the large gear wheel 23 are arranged on the shaft. On the mirror case 9, the worm 25 meshes with the worm wheel 26, and the worm wheel 26 meshes with the large gear 23; the adjustment pull rod 24 axially passes through the pull rod holes 29 on the two rib plates 27, 28 in the mirror case 9, so that 24 pull rods are adjusted It can slide axially, and the normal direction cannot act alone, and can only be flipped together with the mirror housing 9 relative to the rotating plate 10 . One end of the adjusting rod 24 is prov...

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 interior rearview mirror. The function of the rearview mirror is: in the process of driving at night, when the headlights of the rear car illuminate the mirror surface of the interior rearview mirror, the mirror surface will automatically turn over and change its reflectivity, thereby effectively controlling the glare caused by the strong light of the rear lights to the driver. , so that the driver can effectively avoid eye fatigue caused by glare when driving at night, making driving safer. Background technique [0002] The interior rearview mirror is a kind of interior accessory commonly used in various motor vehicles, and it plays a vital role for the driving safety of the automobile. Anti-glare interior rearview mirror plays a more important role for safe driving. At present, the interior rearview mirror capable of anti-glare is basically an electronic anti-glare...
