Description

Technical Field

[0001] The invention relates to the technical field of automobile rearview mirrors, in particular to an electronic rearview mirror. Background Art

[0002] Traditional car rearview mirrors use lenses with fixed viewing angles. Although they help drivers observe the situation around the vehicle to a certain extent, there are still blind spots, especially near the A-pillar, which poses a potential threat to driving safety. With the development of electronic technology, electronic rearview mirrors have gradually replaced traditional rearview mirrors. They usually capture images through cameras and display them on the in-car display screen, providing a wider field of view. However, most electronic rearview mirrors on the market currently still use fixed or limited adjustment angles, failing to fully utilize the flexibility brought by electronic technology.

[0003] Although some electronic rearview mirrors have certain adjustment functions, such as electrically adjusting the angle of the rearview mirror, these adjustments can usually only be performed within one plane and cannot achieve large-angle rotation, so there are still certain field of view limitations. In addition, existing electronic rearview mirrors also have some inconveniences in wiring and installation, such as wires easily interfering with the rotation of the lens and the complicated installation process. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention proposes an electronic rearview mirror with a dual rotating lens. The dual lens design and the rotation function of the lens greatly expand the driving field of view, effectively avoid blind spots such as the A-pillar, and improve driving safety performance. At the same time, the present invention also solves the problems of wire interference and inconvenient installation through a sophisticated wiring groove and annular shaft design.

[0039] The rearview mirror housing 1 has a first viewport 101 at its rear end facing the rear of the vehicle, and a second viewport 102 at its front end away from the corner of the vehicle body. Both the first viewport 101 and the second viewport 102 are made of transparent PC boards;

[0040] The upper shell 5 and the lower shell 6 are installed inside the rearview mirror shell 1. The upper shell 5 and the lower shell 6 are fixedly connected up and down by screws. The upper shell 5 and the lower shell 6 are both provided with snap springs 7, wherein two are provided on the upper shell 5 and one is provided on the lower shell 6. A fixed slot 103 is provided in the rearview mirror shell 1 corresponding to the snap spring 7. The rearview mirror shell 1 is mounted on the upper shell 5 and the lower shell 6;

[0041] The base 2 is fixedly connected to the sides of the upper shell 5 and the lower shell 6 by screws, and a connecting bracket 8 is installed in the inner cavity of the base 2, and the connecting bracket 8 is used to fix the electronic rearview mirror as a whole on the vehicle body;

[0042] A first lens assembly 3 and a second lens assembly 4, which are mounted in an upper housing 5 and a lower housing 6;

[0043] The first lens assembly 3 includes: a first motor 301, a first lens support frame 302, a first lens body 303, and a first annular shaft 304. The output shaft of the first motor 301 is fixedly connected to the first lens support frame 302. The first lens body 303 is mounted in the first lens support frame 302. The first lens support frame 302 is integrally formed with a first annular shaft 304. The first annular shaft 304 is arranged on the opposite side of the first motor 301. The first motor 301 can drive the first lens body 303 to rotate vertically.

[0044] The second lens assembly 4 includes: a second motor 401, a second lens support frame 402, a second lens body 403, and a second annular rotating shaft 404. A driving gear 405 is installed on the output shaft of the second motor 401. The driving gear 405 is meshed with a driven gear 406 for transmitting power. The driven gear 406 is fixedly installed at the bottom of the second lens support frame 402. The second lens body 403 is sleeved in the second lens support frame 402. The top of the second lens support frame 402 is integrally formed with a second annular rotating shaft 404. The second motor 401 can drive the second lens body 403 to rotate horizontally. A limiting boss 601 is installed on the lower shell 6. The limiting boss 601 is arranged on the inner side of the second viewport 102 corresponding to the driven gear 406. The driven gear 406 is set to a fan-shaped structure. The limiting boss 601 is used to limit the rotation angle of the second lens body 403.

[0045] A wiring groove 501 is provided on the top surface of the upper shell 5 and the contact surface with the base 2. The wiring groove 501 is Y-shaped. The input end of the wiring groove 501 corresponds to the wiring port 202 provided on the base 2, and the output end of the wiring groove 501 corresponds to the first annular rotating shaft 304 and the second annular rotating shaft 404 respectively. The annular interior of the first annular rotating shaft 304 and the second annular rotating shaft 404 can lay lines to the first lens body 303 and the second lens body 403. The first annular rotating shaft 304 and the second annular rotating shaft 404 can ensure that the rotation of the first lens body 303 and the second lens body 403 is not affected by the wires.

[0046] The connecting bracket 8 is an integral injection-molded structure, which includes a rearview mirror connecting end 801 connected to the base 2 and a body connecting end 802 connected to the car. A through groove 803 is provided at the center of the body connecting end 802 of the connecting bracket 8. The through groove 803 corresponds to the wiring port 202, which can facilitate wiring. The body connecting end 802 of the connecting bracket 8 is also integrally formed with a hook 804. The hook 804 is a downwardly bent structure. The hook 804 is used to pre-fix it on the car door when assembling the rearview mirror for subsequent installation.

[0048] The working principle of the present invention is as follows: when the driver needs to observe the situation around the vehicle, the first lens assembly 3 and the second lens assembly 4 will respectively capture images in different directions and transmit them to the display screen inside the vehicle. The first lens assembly 3 can be driven by the first motor 301 to realize vertical rotation, so as to observe the situation behind and to the side of the vehicle. The second lens assembly 4 can be driven by the second motor 401 and the gear transmission to realize horizontal rotation, so as to observe the situation to the side and to the front of the vehicle.

[0049] In order to ensure that the connection of the wires is not disturbed when the lens rotates, the present invention adopts the design of a Y-shaped wiring groove and a circular shaft. The wires are laid to the inside of the circular shaft through the Y-shaped wiring groove, and then rotate with the rotation of the lens. The wires are consistent with the rotation axis of the lens, and there will be no pulling, so the rotation of the lens will not be disturbed;

[0050] A through slot 803 is provided at the center of the body connection end 802 on the connection bracket 8 to facilitate the passage of wires. A downwardly bent hook 804 on the body connection end 802 is used to pre-fix it on the vehicle door during assembly, thereby simplifying the installation process.

[0051] The electronic rearview mirror of the present invention significantly improves the breadth of the driving field of view, reduces blind spots, and enhances driving safety performance through a dual-lens design and a free rotation function. At the same time, through a sophisticated wiring slot and annular shaft design, it solves the problems of wire interference and inconvenient installation, providing the driver with a more convenient and safe driving experience.
