Technical Field
[0001] This utility model relates to a vehicle rearview mirror, and more particularly to a rearview mirror structure. Background Technology
[0002] Car rearview mirrors are located on the left and right sides of the front of the car, and also in front of the interior. They reflect the situation behind, to the sides, and below the car, allowing the driver to indirectly see these areas; they act as a "second eye," expanding the driver's field of vision. With technological advancements, rearview mirrors installed inside cars are commonly equipped with motorized mirrors. These motorized mirrors have dual functions: they can be used as ordinary reflectors to reflect the movement of vehicles behind, and they can also be used as electronic displays to show images of vehicles behind.
[0003] However, the two uses mentioned above require different viewing angles from the driver. When used as a regular reflector, the mirror must face directly behind, and the human eye's observation axis must be perpendicular to the mirror. But when the rearview mirror is adjusted to function as a display screen, in order to minimize glare, the viewing angle of the mirror needs to be adjusted so that it is slightly offset from the human eye's observation axis. Therefore, an angle adjustment mechanism needs to be installed on the rearview mirror, which is usually installed inside the housing.
[0004] Existing in-vehicle streaming rearview mirrors generally include a housing, a reflector, a display module, and a pivot bracket. The housing typically has a front housing for mounting the reflector, a central support plate for mounting the display module, a pivot bracket mounted on the central support plate, a rear housing covering the rear side of the central support plate, and a rear cover plate that closes the rear housing. When assembling this in-vehicle streaming rearview mirror, the reflector is first installed in the front housing, then the display module is installed between the central support plate and the front housing, the rear cover plate is installed on the central support plate, the pivot bracket is installed on the central support plate through an opening in the rear housing, and finally the rear cover plate is used to close the opening in the rear housing from both sides. The assembly is complex, and the overall stability of the housing is poor.
[0005] Therefore, there is an urgent need for a rearview mirror structure that can solve the above problems. Utility Model Content
