Description

Structure is adjusted to base plate for interior mirror

Technical Field

The utility model relates to the technical field of auto-parts, specifically interior base plate for rear-view mirror adjusts structure.

Background

The vehicle interior rear-view mirror is generally installed on a front windshield in a vehicle, and a driver can acquire relevant information behind the vehicle in a certain visual field range through the vehicle interior rear-view mirror, so that the vehicle interior rear-view mirror is an important auxiliary component for safe driving of the vehicle. With the development of electronic technology, the application of the inner rearview mirror is expanded to develop an anti-glare electric rearview mirror, and the anti-glare electric rearview mirror generally comprises a special electrochemical layer mirror surface, a photoelectric sensor and an electronic controller. The electronic controller receives the light irradiation intensity signal transmitted by the photosensitive diode, and if the light of the rear vehicle is stronger than that of the front vehicle, the electronic controller outputs a voltage to the mirror surface to change the color of the mirror surface electric layer. The higher this voltage, the greater the change in colour of the electrochemical layer. After the color of the electric layer is changed, the light reflected to the eyes of the driver by the electric rearview mirror is obviously weakened, so that the vision of the driver is not influenced, and the comfort and the safety of driving and riding the vehicle are improved. The manual anti-dazzling electric inside rear-view mirror display screen displays the streaming media on the reflector, and the reflector is glass with certain reflectivity, so that the reflector can be used as a mirror surface when the content of the streaming media is not displayed, and a driver can directly observe the road condition behind a vehicle through the reflection of the mirror surface. Whether the streaming media is displayed or not is controlled by a control switch on the circuit board, namely the switch is electrically connected with the display screen. The rear of the shell is connected to the connecting rod through the spherical hinge assembly, so that a driver can hold the inner shell and adjust the height of the shell to enable the reflector to be just opposite to a rear windshield of the vehicle body, and the reflector of the inner rearview mirror can display road conditions right behind the vehicle. However, when the direct rear outside of the vehicle is irradiated by the strong light of another vehicle, the reflector of the inside rear view mirror is directly opposite to the strong light, and the eyes of the driver are also irradiated by the strong light, so that the content of the streaming media displayed by the reflector of the inside rear view mirror cannot be seen clearly. Generally, a black small shifting piece is arranged on the back surface (generally at the center lower end) of an interior rearview mirror of a manual anti-dazzling electric interior rearview mirror, the shifting piece faces the front windshield in a normal state, and the mirror surface of the interior rearview mirror can slightly change angles as long as the shifting piece is slightly shifted towards the interior of the vehicle.
