Description
Technical Field
The utility model relates to an automobile interior rear-view mirror lens and no frame automobile interior rear-view mirror.
Background
The technical limitation of the prior electro-luminescent lens of the automatic anti-dazzle eyepiece is met, the prior automatic anti-dazzle inner rear-view mirror is a wider frame, the frame is used for compressing the electro-luminescent lens to fix the electro-luminescent lens and ensure the conductive effect, and the electrode plate is covered by the wide frame to influence the attractiveness of the inner rear-view mirror. However, this structure adversely affects the overall aesthetic effect of the interior rear view, and more importantly, the reflective area of the mirror surface is reduced, which affects the field of vision of the driver. Accordingly, the present company has developed frameless and narrow-framed interior mirrors for automobiles, which are mounted in the cab of the automobile through brackets. Such an interior mirror can improve driving safety by sufficiently enlarging the field of vision of the driver. But the frameless inside rearview mirror needs to meet the requirements of production standards on the edge radian. The existing automobile interior rear-view mirror comprises a front piece of glass, a rear piece of glass and two pieces of glass with the same thickness, and the thickness of the existing automobile interior rear-view mirror is smaller, so that the existing automobile interior rear-view mirror cannot meet the requirements of production standards, and the production and application of the existing automobile interior rear-view mirror without a frame are influenced. Furthermore, the edge design of the glass of today also has a large impact on the driver's view.
Disclosure of Invention
The utility model aims to provide a: an automobile inner rear-view mirror lens which meets the production requirement and improves the driving safety and an automobile inner rear-view mirror developed by the lens are designed.
The technical scheme of the utility model includes preceding glass and back glass, and its technical scheme is: the thickness of the front glass is larger than that of the back glass, the side face of the front glass comprises a first cambered surface, and the curvature radius of the first cambered surface is 2.5-3.2 mm.
Specifically, the first cambered surface is connected with the front surface of the front glass through a first transition cambered surface
Similarly, a second transition cambered surface is arranged between the first cambered surface and the rear surface of the front glass.
Furthermore, a plane is arranged between the first cambered surface and the second transition cambered surface. In this case, the angle between the plane and the rear surface of the front glass is preferably a degree.
In addition, a second cambered surface can be arranged between the first cambered surface and the second transition cambered surface, and the curvature radius of the second cambered surface is 0.8-1.2 mm.
In general, the thickness of the front glass is 2.5 to 3.2mm, and the thickness of the rear glass is 1.6 to 2.3 mm. Preferably, the sum of the thicknesses of the front glass and the rear glass is 4.8 mm.
The utility model discloses still include by as before the no frame automobile interior rear-view mirror that the automobile interior rear-view mirror lens was made.
The utility model discloses the structure to two lenses around current automobile interior rear-view mirror has made the improvement, makes the actual production that can realize no frame automobile interior rear-view mirror to make the automobile interior rear-view mirror of large field of vision become reality, improve the security of auttombilism.

Detailed Description
Example one
As shown in the figure, the present embodiment includes an automotive interior mirror lens, which includes a front glass 1 and a rear glass 2, wherein the thickness of the front glass 1 is 2.5mm, the thickness of the rear glass 2 is 2.3mm, and the thickness error of the front and rear glasses 2 is ± 0.2 mm. The side of the front glass 1 is provided with a first cambered surface 4, and the first cambered surface 4 is connected with the front surface and the rear surface of the front glass 1 through a first transition cambered surface 3 and a second transition cambered surface 7 respectively. The two transition cambered surfaces ensure that the front glass 1 is not easy to damage by smoothing the edge of the front glass 1. There is no other special requirement for the radius of curvature of the two transition arcs. The corner portion of the front glass 1 of the present embodiment is smoothly transitioned. The structure between the rear glass 2 and the front and rear glasses 2 of the present embodiment is the prior art, and is not described herein again.
The automobile interior rear-view mirror lens described in this embodiment is mounted on the bracket by using the prior art to form a frameless automobile interior rear-view mirror.
Example two
As shown in the figure, the present embodiment includes an automotive interior mirror lens, which includes a front glass 1 and a rear glass 2, wherein the thickness of the front glass 1 is 3.0mm, the thickness of the rear glass 2 is 1.8mm, and the thickness error of the front and rear glasses 2 is ± 0.2 mm. There is first cambered surface 4 preceding glass 1 side, and first cambered surface 4 is connected through first transition cambered surface 3 with preceding glass 1 front surface, and the rear side of first cambered surface 4 passes through plane 5 to be connected with second transition cambered surface 7, and second transition cambered surface 7 connects the rear surface of preceding glass 1.
