The function of the car rearview mirror assembly
The rearview mirror assembly of a car (also known as the rearview mirror assembly) is an important safety component of a vehicle. Its main function is to provide the driver with a rear view and integrate multiple auxiliary functions to enhance driving safety.
Main functions
Youdaoplaceholder0 field of view provides
The reflective mirror surface clearly presents the information of vehicles, pedestrians and road conditions behind, helping drivers determine the distance between vehicles and the timing of lane changes, and ensuring lane change safety.
Youdaoplaceholder0 Angle adjustment
Equipped with a rotating motor, it enables multi-directional adjustment of the mirror surface (up and down, left and right), catering to the viewing Angle requirements of different drivers and enhancing the convenience of use.
Youdaoplaceholder0 automatically fold/unfold
When locking the car, it automatically folds to reduce the risk of scratches. When unlocking, it automatically unfolds to save operation time and reduce wind resistance to improve fuel economy.
Youdaoplaceholder0 heating demisting
Quickly remove frost or fog from the mirror surface through heating elements to ensure clear vision in rainy and snowy weather.
Youdaoplaceholder0 integrated accessibility
Some models are equipped with intelligent systems such as blind spot monitoring and automatic anti-glare, further enhancing driving safety.
Structural features
Youdaoplaceholder0 shell : The internal components are protected by high-strength materials (such as heat-resistant ABS, PC/ABS), taking into account both aesthetics and aerodynamic design.
Youdaoplaceholder0 mirror : Clear reflection is achieved through optical design. Common materials include high-gloss ASA, PMMA/ASA, etc.
Faults in the rearview mirror assembly of a car may involve various issues. The following are common causes and solutions:
Common causes of faults
Youdaoplaceholder0 Mechanical structure problem : Poor lubrication due to excessively low temperature or increased resistance due to dust accumulation in the extension mechanism may cause folding failure.
Youdaoplaceholder0 Motor failure : Damage to the rearview mirror motor may result in inability to adjust or abnormal folding.
Youdaoplaceholder0 Accessory quality issues : Some cases show that second-hand accessories or accessories with quality defects may cause frequent malfunctions.
Youdaoplaceholder0 Circuit issue : A short circuit in the circuit or a blown fuse may affect the heating or folding function.
Solution
Youdaoplaceholder0 Environmental improvement : Pay attention to anti-freezing maintenance in winter to avoid the low-temperature environment affecting the mechanical structure.
Youdaoplaceholder0 Cleaning and maintenance : Regularly clean the dirt on the surface of the rearview mirror to prevent oil stains, glue and other contaminants from adhering and affecting the view.
Youdaoplaceholder0 Replace parts : If you need to replace the entire assembly, it is recommended to confirm the source of the parts through a 4S store or a third-party testing institution to avoid using second-hand parts.
Youdaoplaceholder0 Professional maintenance : When motor or circuit faults are involved, they must be inspected and repaired by professional institutions.
If any abnormality is found in the rearview mirror assembly, it is recommended to contact the 4S store or a professional repair point in a timely manner to investigate the specific cause of the fault.
The rearview mirror of a car is not an ordinary mirror; it is a convex mirror. Many car owners believe that the rearview mirror of a vehicle operates based on the principle of light reflection. In fact, this statement is incorrect. Strictly speaking, the rearview mirror of a vehicle operates based on the principle of light refraction.
So the rays perpendicular to the convex mirror are not parallel. There is an Angle between each ray, and this Angle is fan-shaped outward. In this way, the distant scenery will shrink as the Angle of the sector forms, and the mirror image displayed in the convex mirror will be smaller. Thus, more distant scenery can be accommodated inside the rearview mirror.
The function of the vehicle's rearview mirror is extremely important. It is far from enough for car owners to merely know the working principle of the rearview mirror. They also need to adjust the rearview mirror correctly. This can ensure the driver's field of vision and avoid potential safety hazards caused by insufficient vision.
