Problems solved by technology
In order to solve the problem of the outer blind area, the multi-angle prism lens, the additional rearview mirror, and the rearview mirror hinged by the outside of two lenses, etc. mentioned in the existing scheme technology, these solutions can play a certain role in solving the outer blind area problem. However, most of them have a large structure size, are not compact, not beautiful, and are not widely used. In particular, they cannot provide real-time protection for segmented lenses, and the rainproof effect is poor, so they are not widely used.

The invention discloses an automobile rearview mirror without a blind area. The automobile rearview mirror comprises protective covers, curved optical mirrors arranged in the protective cover, and a mirror regulating device driving the curved optical mirrors to rotate. The curved optical mirrors comprise a first mirror and a second mirror in hinge connection, the protective covers comprises a fixed cover and a movable cover matched with the fixed cover, the first mirror and the second mirror are arranged in the fixed cover and the movable cover respectively, the second mirror is connected with the movable cover, and the mirror regulating device is connected with the first mirror and the second mirror. The two curved optical mirrors are respectively controlled to rotate at different angles through the mirror regulating device so that an ideal automobile driving view angle can be obtained. Besides a basic view angle of an ordinary rearview mirror, an expanded outer side view angle of an automobile can also be obtained, so that the blind area is eliminated, and driving safety is improved. Meanwhile, the protective covers can provide real-time protection for the mirrors, and therefore, dust-prevention and rain-proof effects are achieved.
Description
technical field [0001] The invention belongs to automobile rearview mirrors, in particular to an automobile rearview mirror without blind spots. Background technique [0002] At present, automobile technology is developing rapidly, and the improvement and innovation of automobile rearview mirrors are also in progress. Taking a car as an example, during driving, the viewing angle A of a common rearview mirror is as follows: figure 1 As shown, there are several blind spots in this situation, the front blind spot, the rear blind spot, the rearview mirror inner blind spot and the rearview mirror outer blind spot. In order to solve the problem of the outer blind area, the multi-angle prism lens, the additional rearview mirror, and the rearview mirror hinged by the outside of two lenses, etc. mentioned in the existing scheme technology, these solutions can play a certain role in solving the outer blind area problem. However, most of them have a large structure size, are not comp...
