TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle rearview mirror, in particular to a wide-angle automobile rearview mirror. BACKGROUND

[0002] The interior rearview mirror is a plane mirror for the interior of a vehicle, through which the driver can see the vehicle behind the rear windshield. Compared with the left and right exterior rearview mirrors, the interior rearview mirror can more truly reflect the distance between the vehicles. In order to increase the viewing angle of the rear, some wide-angle rearview mirrors usually have a lengthened mirror surface, which is set in a trapezoidal shape with a narrow upper part and a wide lower part.

[0003] However, the interior rearview mirror can only see the oncoming vehicle behind the vehicle, but cannot see the rear space in the vehicle. In actual use, if the rear seat is occupied by a child, the driver can only look back frequently, which is quite inconvenient. In order to facilitate the driver to see the rear space in the vehicle, there is a rearview mirror that is installed independently of the interior rearview mirror. However, in use, the interior rearview mirror has occupied the installation position, so that the rearview mirror can only be installed at the rear of the vehicle. When the driver looks at the rear space in the vehicle, he needs to lean back to obtain a viewable angle, which is also inconvenient. SUMMARY

The detection values of the first rotation angle sensor and the second rotation angle sensor can feed back the components in the two coordinate systems. If the vehicle is in a driving state, it is detected by the acceleration sensor. At this time, the first motor does not drive the plane mirror to flip, and the wide-angle automobile rearview mirror is used as a rearview mirror. If the vehicle is in a parking state, it is also detected by the acceleration sensor. At this time, the first motor quickly drives the plane mirror to flip, and the wide-angle automobile rearview mirror is used as a rearview mirror. At the same time, since the rearview mirror is flexibly connected through the spring and the connecting seat, the position correction of the support frame in one dimension can be realized through the second motor, and the position correction of the support frame in another dimension can be realized through the first motor. Thus, the position correction of the rearview mirror in two dimensions is realized, and the two dimensions correspond to the offset of the specific position of the rearview mirror after installation relative to the rear. And, according to the different specific requirements of different drivers for the direction of the wide-angle automobile rearview mirror, the rearview mirror flipped out can be directed to the rear through the angle detection assembly, the first motor, the second motor, etc. And combined with the actual needs, it is realized that the wide-angle automobile rearview mirror is used as a rearview mirror when the vehicle is driving, and is used as a rearview mirror when the vehicle is parked, creating a safe use environment.

[0027] In the embodiment, the wide-angle automobile rearview mirror combines the traditional interior rearview mirror and the rearview mirror, so that the wide-angle automobile rearview mirror combines the two kinds of mirrors. As described in the background art, the interior rearview mirror occupies the installation position, so that the rearview mirror lacks a suitable position for installation. However, the installation requirements of the rearview mirror are slightly different from those of the interior rearview mirror. The interior rearview mirror needs to be installed in a position where the field of view is directed to the rear windshield. Therefore, when installed on the front windshield, the mirror surface is not directed to the rear, but is relatively left and downward. When the rearview mirror is installed, the mirror surface needs to be directed to the rear, so that the interior rearview mirror can be seen. Therefore, in the embodiment, the wide-angle automobile rearview mirror is provided with an angle detection assembly 7 between the supporting leg 1 and the clamping seat 6 to feed back the specific position of the installed interior rearview mirror. Because the ball head 2 is clamped in the spherical clamping groove 24, no matter how the bottom shell 3 and the plane mirror 4 rotate relative to the ball head 2, the center point of the ball head 2 and the center point of the spherical clamping groove 24 always coincide, so that the rotation of the bottom shell 3 and the plane mirror 4 relative to the ball head 2 can be decomposed into components in two coordinate systems. The detection values of the first rotation angle sensor 11 and the second rotation angle sensor 12 can feed back the components in the two coordinate systems.

[0028] In the embodiment, if the vehicle is in a driving state, it is detected by the acceleration sensor. At this time, the first motor 16 does not drive the plane mirror 4 to flip, and the wide-angle automobile rearview mirror is used as a rearview mirror. If the vehicle is in a parking state, it is also detected by the acceleration sensor. At this time, the first motor 16 quickly drives the plane mirror 4 to flip, and the rearview mirror 19 is flipped out, so that the wide-angle automobile rearview mirror is used as a rearview mirror. At the same time, since the rearview mirror 19 is flexibly connected through the spring 18 and the connecting seat 17, the position correction of the support frame 21 in one dimension can be performed through the second motor 22, and the position correction of the support frame 21 in another dimension can be performed through the first motor 16. Thus, the position correction of the rearview mirror 19 in two dimensions is realized, and the two dimensions correspond to the offset of the specific position of the installed interior rearview mirror relative to the rear. In addition, according to the specific requirements of different drivers for the direction of the wide-angle automobile rearview mirror, the flipped-out rearview mirror 19 can be directed to the rear through the angle detection assembly 7, the first motor 16, the second motor 22, etc. In addition, according to the actual needs, the wide-angle automobile rearview mirror can be used as a rearview mirror when the vehicle is driving, and can be used as a rearview mirror when the vehicle is parking, so that a safe use environment is created.
