What is a car rearview mirror
The rearview mirror of a car is a mirror installed at the rear or side of the vehicle. It is mainly used to observe the road conditions behind when reversing or parking, ensuring driving safety.
Core function
The rearview mirror helps drivers observe the traffic environment behind and on both sides of the vehicle in real time by reflecting light. Especially when reversing into a parking space, parking sideways or meeting oncoming vehicles, it can reduce blind spot interference and avoid scraping obstacles or pedestrians.
Structural features
Youdaoplaceholder0 location : Usually located at the rear of the vehicle or on both sides of the driver's and front passenger seats, some models are equipped with in-car rearview mirrors as supplementary
Youdaoplaceholder0 Mirror type : Convex mirrors (with a wider reflection range) or plane mirrors (to reduce distortion) are used. Some high-end models adopt anti-glare design
Youdaoplaceholder0 adjustment method : Supports electric adjustment, heating defrosting and other functions. Some models are equipped with an automatic downward-flipping function
Usage skills
Youdaoplaceholder0 adjustment method : taking the distant horizon as the reference, adjust until the image in the mirror occupies 1/4 of the mirror surface area
Youdaoplaceholder0 Lane change reference : Observe the position of the vehicle behind the left through the left rearview mirror, and confirm the distance of the vehicle behind the right through the right rearview mirror
The rearview mirror of a car plays a significant role in scenarios such as reversing and parking. It can effectively expand the driver's field of vision and enhance driving safety.
Reversing assist function
The rearview mirror can be used to observe the blind spots on both sides and at the rear of the vehicle, especially the tire positions, low obstacles (such as stone blocks, pets), and side dead corners, preventing scratches.
Parking assistance
By adjusting the Angle of the rearview mirror, the distance between the vehicle and the edge of the parking space or obstacles can be accurately determined, assisting in operations such as reversing into a parking space and parallel parking. Some models are equipped with an automatic rollover function, which automatically adjusts the Angle when reversing to clearly display the ground conditions.
Nighttime protection
Some high-end models are equipped with anti-glare functions that can automatically adjust the color depth of the lenses to reduce the interference of strong light from vehicles behind at night. The heating function can remove the water mist on the mirror surface in rainy and foggy weather, keeping the view clear.
Field of view optimization
Reasonably adjusting the Angle of the rearview mirror (such as the horizon being in the center of the mirror surface and the vehicle body occupying 1/4 of the area) can take into account the dynamics of the vehicles behind and the observation of the surrounding environment, enhancing safety when changing lanes and turning.
Common faults of car rearview mirrors include lens damage, adjustment failure, heating failure, and aging of the casing, etc. The specific causes and solutions are as follows:
The lens is damaged
Lens damage or cracks are usually caused by impact or external force, and the lens or assembly needs to be replaced. Some models support individual lens replacement, but it is necessary to match the original factory specifications to avoid field of view distortion.
Adjustment failure
Motor failure, short circuit in the circuit or damage to the switch may result in inability to adjust. It is necessary to check the circuit and component functions. If a short circuit is found in the line, the wires need to be repaired. If the switch is faulty, it needs to be replaced.
Heating failure
A broken heating wire or a blown fuse will cause the heating function to fail. The fuse and heating wire circuits need to be inspected. If they are blown, they should be replaced.
The shell is aging.
Sun exposure or chemical corrosion can easily cause the shell to crack and fade. It is necessary to avoid direct sunlight in daily life. When replacing, it is recommended to use high-temperature resistant and impact-resistant materials (such as ABS engineering plastic).
Abnormal folding function
Electric folding malfunctions may be caused by battery power-off, foreign object jamming or motor damage. It is necessary to check the battery status, remove foreign objects or replace the motor.
Youdaoplaceholder0 Maintenance suggestion : For issues involving circuits or mechanical structures, it is recommended to have them inspected at a professional repair point. Self-handling may cause secondary malfunctions. When replacing parts, give priority to choosing original or compatible models to avoid matching problems.
