8 Car Rearview Mirror Design Secrets

1. Why is there a line on the outside rearview mirror?

Many cars have a line on the outside rearview mirror, and the two mirrors separated by this line see the object is different, and such an outside rearview mirror is a double curvature mirror. The curvature of the mirror near the window is smaller than the other side, and the outside mirror is not only curved but also has a wider range of viewing angles so that the driver can notice the behavior of the rear vehicle earlier and make better responses.

2. How is the external rear-view mirror to prevent dazzle?

When the driver is driving, the sensor equipped with the anti-glare external rearview mirror will monitor the intensity of the rear light in real-time and automatically adjust the mirror reflection effect. When the rear vehicle lights glare, the anti-glare external rearview mirror can be reflected on the mirror light becomes dim and soft; When there is no harsh light in the rear, the mirror reflection effect immediately returns to normal, ensuring a stable and good rear vision to improve night driving safety.

3. Is the exterior rearview mirror flat?

The exterior rear-view mirror is usually not a flat mirror, but a convex mirror. The convex mirror is used because although the convex mirror image is smaller than the visual effect, it brings a large field of view, which can help the owner to better observe the rear of the car.

4. Are the exterior mirrors symmetrical?

In many people's inherent cognition, the left and right exterior mirrors are symmetrical, but in fact, the left and right exterior mirrors are not symmetrical. It should be known that the mirror on the driver's side of the car is large and the curvature is small, and the mirror on the other side is small and the curvature is large, so as to ensure that the driver's left and right sides of the field of view are consistent to the maximum extent, which is more conducive to the driver's observation of the rear road conditions. As a result, some left-hand cars have larger mirrors on their left side; Some right-hand cars have larger mirrors on their right side. In general, the position of the left side mirror and the right side mirror on most cars is not the same.

5. What kind of design is a low wind resistance external rearview mirror?

Low wind resistance external rearview mirror fully follows the aerodynamic design, the rearview mirror seat is mostly a conical thin rod, cone head, and the edge of the rearview mirror shell is fixed together, the edge is mostly a circular arc, to reduce the wind resistance. At the same time, there is A common water drop type low wind resistance external rearview mirror, which uses a large curved streamline shape, and moves down to the window at the body connection, which can increase the window area and reduce the A-pillar blind area.

6. Why do some cars have a small "horn" next to the rearview mirror?

Such small "horn" designs, formally known as "deer whistles," are not found everywhere, and vehicles in forested areas may have them. For example, in the Hokkaido region of Japan, deer whistles will be installed, and when the car is driven, it will make sounds that people cannot hear but deer do not like, in order to drive the deer away and ensure driving safety.

7. Why are some exterior mirrors on the front door and some exterior mirrors on the triangular window?

The exterior mirrors of most of our family cars are designed on the triangular Windows, for sitting considerations, and the exterior mirrors on the triangular Windows are more in line with our riding habits and are easy for the driver to observe. Of course, in some cars due to design reasons, such as the A-column design being relatively low, etc., but also in order to give the occupant the maximum transparent space, the base of the external rearview mirror will be designed on the door, so that it will need A slightly longer connecting rod to connect the external rearview mirror to ensure the driver's field of view. The external rear-view mirror on the front door model, it is worth saying that rally cars often install the external rear-view mirror relatively far back, this is because the seat in the car is also far back; In order to avoid the driver's vision being affected, the external rear-view mirror is naturally installed on the door.

8. Why has the hidden exterior rearview mirror not yet been mass-produced?

The hidden external rearview mirror is to cancel the current exposed external rearview mirror, on the one hand, to reduce wind resistance, on the other hand also to enhance the sense of science and technology, the reason why there is no mass production, there are many reasons.

First, the law does not allow, in many countries, the rearview mirror and the rear fog light, as a car product must have the configuration. Second, user habits. Now car users have been used to observing the external rearview mirror, the use of the hidden external rearview mirror, may produce many safety problems. Third, if a camera is used to replace the external rearview mirror function, there will be a series of problems such as glare, which will have an adverse impact on driving safety.
