Rearview Mirror

Abstract

Automotive rearview mirrors include mirror frames, transparent lenses, elastic reflective films, spherical elements, inert gases, and intake and exhaust devices. The mirror frame has a first channel and a second channel. The transparent lens, the elastic reflection film and the spherical element are successively accommodated in the frame. The elastic reflective film layer has a reflective surface facing the transparent lens. The spherical element has a spherical surface facing the elastic reflective film. There is a first cavity communicated with the first channel between the transparent lens, the elastic reflective film and the frame, and a second cavity communicated with the second channel between the spherical element, the elastic reflective film and the frame. The inert gas is selectively located in the first cavity or the second cavity. The intake and exhaust device is connected between the first channel and the second channel. The car rearview mirror can selectively realize a larger rear view range and avoid distortion of rear view objects according to actual driving needs, so as to effectively reduce the visual blind spot of the car rear view.

Description

technical field [0001] The invention relates to the technical field of automobiles, and in particular to an automobile rearview mirror. Background technique [0002] The car rearview mirror is an important safety component of the car. The driver observes the rear, side and bottom of the car through the left and right rearview mirrors respectively. Therefore, the car rearview mirror acts as the "second eye" of the driver, expanding the scope of the driver. field of view. [0003] Generally speaking, based on people's vision habits and the accuracy and safety of judging rearview objects, flat lenses should be the best choice for rearview mirror lenses, because flat lenses have no distortion of rearview objects and can truly reflect the The real shape and the actual distance of the rear object have the advantage of more accurate judgment information for the driver. However, the rear vision range of the plane lens is small, and there are more visual blind spots. [0004] In o...

Problems solved by technology

Although double-curvature lenses and variable-curvature lenses can make up to a certain extent for the lack of too small rear-view range of flat lenses and the unrealistic reflection of objects behind the vehicle by spherical lenses, the rear-view range of rear-view mirrors using double-curvature lenses or variable-curvature lenses It is still too small to meet the actual driving needs, and there are still more visual blind spots in some special cases, especially when the car is turning
