At that time, she thought it was dangerous that the car could not observe the rear, so it might be inspired by the mirror. In the handbook "Women and Cars" published by 1906, she took the lead in putting forward the viewpoint of observing the rear situation with a mirror. This is the prototype of the car rearview mirror.
If "Mercedes-Benz I" made by Karl Benz 1886 is defined as "the first modern car", the rearview mirror first appeared about 20 years later than the car.
In the first Indy 500 race of 19 1 1, Ray Harron, an engineer and racer of Marmon Company in the United States, turned the rearview mirror from theory into reality for the first time. Because the rearview mirror was used in the race, his car no longer needed the assistance of the co-pilot (responsible for observation), so he won the championship easily. So, other drivers followed suit.
Finally, ten years later, in 192 1 year, an inventor named Elmberg obtained a patent for the rearview mirror, named it "COP-SPOTTER" and started mass production in his own company. As a result, rearview mirrors were officially popularized in civilian cars.
This is the development of the whole rearview mirror.
In the subsequent historical evolution, the rearview mirror is also constantly changing. For example, most of the early exterior rearview mirrors were round, only on the driving side. It is said that the traffic situation at that time did not require the assistance of the right rearview mirror. After all, there are few cars and wide roads.
In the first generation of Beetle models, the inner rearview mirror has appeared, and the shape of the outer rearview mirror has also adopted a square with a wider field of view.
The design of rearview mirrors on both sides of the front cover began to appear in the 1960s and 1970s. I always thought this design was tasteless, and later it was really eliminated by history. I think one of the reasons must be that "the distance is far away, which is not conducive to the driver to see the situation behind."
