Description

Technical Field

[0001] The invention relates to the technical field of vehicle-mounted rearview mirrors, and in particular to a wide-angle vehicle rearview mirror. Background Art

[0002] The interior rearview mirror is a plane mirror used inside the vehicle. Through the interior rearview mirror, you can see the vehicle behind the rear windshield. And compared with the left and right rearview mirrors outside the car, the interior rearview mirror can more accurately reflect the distance between vehicles. In order to increase the viewing angle of the rear, some wide-angle rearview mirrors usually extend the mirror surface and set the mirror surface in a trapezoidal shape with narrow top and wide bottom.

[0003] However, when using the rearview mirror inside the car, you can only see the vehicles coming from behind the car, but you cannot see the rear space inside the car. In actual use of the car, if there are children sitting in the back seat, the driver can only look back frequently, which is quite inconvenient. In order to facilitate the driver to see the rear space inside the car, there is a rearview mirror installed independently of the rearview mirror inside the car. However, it was found during use that the rearview mirror inside the car has occupied the installation position, so that the rearview mirror can only be installed against the rear of the vehicle. When the driver looks at the rear space inside the car, he needs to lean his upper body back to obtain a viewing angle, which is also inconvenient. Summary of the invention

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, so that the viewing mirror is turned out, and the wide-angle automobile rearview mirror is used as a viewing mirror. At the same time, since the rearview mirror is flexibly connected to the connecting seat through the spring, the second motor can be used to correct the position of the support frame in one dimension, and the first motor can be used to correct the position of the support frame in another dimension. In this way, the position correction of the rearview mirror in two dimensions is achieved, and these two dimensions correspond to the offset of the specific position of the interior rearview mirror after installation relative to the rear. In addition, according to the different specific requirements of different drivers for the direction of the wide-angle car rearview mirror, the flipped rearview mirror can be directed to the rear through the angle detection component, the first motor, the second motor, etc. In addition, combined with actual needs, it can be used as a rearview mirror when the vehicle is driving and as a rearview mirror when the vehicle is parked, creating a safe use environment.

DETAILED DESCRIPTION

[0024] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0025] In one embodiment, Figures 1 to 4 shown.

There is a first motor 16 for driving the connected arc tooth plate 15. The first motor 16 corrects the position of the axial support plate 14 around the rotating connecting shaft 13 according to the detection value of the first rotation angle sensor 11. Connecting seats 17 are respectively provided at both ends of the axial support plate 14. Each connecting seat 17 is connected to a rearview mirror 19 through two springs 18. A swivel seat 20 is provided in the middle position of the axial support plate 14. A support frame 21 is rotatably connected to the swivel seat 20. The rearview mirror 19 is fixed on the support frame 21. The rotation axis of the support frame 21 is perpendicular to the rotating connecting shaft 13. A second motor 22 for driving the connected support frame 21 is provided on the axial support plate 14. The second motor 22 corrects the position of the support frame 21 around its rotation axis according to the detection value of the second rotation angle sensor 12; a control board 23 with an acceleration sensor is provided in the bottom shell 3. The acceleration sensor is used to detect whether the vehicle is in a driving state. The first motor 16 also drives the plane mirror 4 to flip over according to the detection result of the acceleration sensor.

[0027] In this embodiment, the wide-angle automobile rearview mirror is combined with a viewing mirror on the basis of a traditional interior rearview mirror, so that the wide-angle automobile rearview mirror combines the two mirrors into one. As described in the background technology, since the interior rearview mirror occupies the installation position, the viewing mirror lacks a suitable position for installation. However, the installation requirements of the viewing mirror are slightly different from those of the interior rearview mirror. The interior rearview mirror needs to face the position of the rear windshield of the car because of the need for a field of vision. Therefore, when installed on the front windshield, its mirror surface is not facing directly behind, but relatively to the left and below. When the viewing mirror is installed, its mirror surface needs to face directly behind, so that the rear space in the car can be seen. Therefore, the wide-angle automobile rearview mirror in this embodiment, through the angle detection component 7 arranged between the support foot 1 and the card seat 6, feedbacks the specific position of the interior rearview mirror after installation. Because the ball head 2 is stuck in the spherical slot 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 always coincides with the center point of the spherical slot 24, so the rotation of the bottom shell 3 and the plane mirror 4 relative to the ball head 2 can be decomposed into components on two coordinate systems. Among them, the detection value of the first rotation angle sensor 11 and the detection value of the second rotation angle sensor 12 can feed back the components on these two coordinate systems.

[0028] In this embodiment, if the vehicle is in a driving state, it is detected by the acceleration sensor. At this time, the first motor 16 will 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, so that the rearview mirror 19 is turned out, and the wide-angle automobile rearview mirror is used as a rearview mirror. At the same time, since the rearview mirror 19 is flexibly connected to the connecting seat 17 by the spring 18, the second motor 22 can be used to correct the position of the support frame 21 in one dimension, and the first motor 16 can be used to correct the position of the support frame 21 in another dimension. Thus, the position correction of the rearview mirror 19 in two dimensions is achieved, and these two dimensions correspond to the specific position of the interior rearview mirror after installation relative to the offset of the rear. In addition, according to different specific requirements of different drivers for the direction of the wide-angle automobile rearview mirror, the angle detection component 7, the first motor 16, the second motor 22, etc. can make the flipped rearview mirror 19 face the rear. And combined with actual needs, it can be used as a rearview mirror when the vehicle is driving and as a rear-view mirror when the vehicle is parked, creating a safe use environment.
