The inner rear-view mirror utilizing the front glass in the embodiment comprises a lens, wherein the lens comprises the front glass and a back glass, and the front glass is the front glass of the inner rear-view mirror.

The inner rear-view mirror utilizing the front glass comprises a lens, wherein the lens comprises the front glass and a rear glass, and the lens is the inner rear-view mirror lens.

The utility model discloses a design can reduce the thickness of glass before the inside rear-view mirror of car under the prerequisite that satisfies national standard's requirement to can reduce the whole weight of inside rear-view mirror of car, reduction in production cost further improves the stability of inside rear-view mirror in the use simultaneously.

Drawings

FIG. 1 is a partial cross-sectional view of the front mirror and the inner mirror of the automobile according to the present invention;

the glass comprises a glass body, a cambered surface, a first layer of glass, a rear layer of glass, a conductive layer, an electrochromic material layer, a rubber frame and a second layer of glass, wherein the cambered surface is 1, the first layer of glass is 2, the rear layer of glass is 3, the conductive layer and the electrochromic material layer are 4, and the rubber frame is 5.

Detailed Description

As shown in the drawings, fig. 1 shows the structure of the front glass of the lens of the inside rear view mirror and the lens made of the glass.

In fig. 1, first, the front glass of the mirror plate of the inside rear-view mirror for a vehicle is shown, and the front glass is composed of a flat first glass layer 2, and the edge of the front surface of the first glass layer 2 is a cambered surface 1. The cambered surface 1 refers to the main part of the transition of the front surface and the back surface of the first layer of glass 2, or refers to the functional part of the first layer of glass, and does not include the cambered surface of the process transition between the cambered surface 1 and the front surface and the back surface of the first layer of glass 2.

In this embodiment, at each point on the arc surface 1, the center of the arc line passing through the point along the arc surface and having the smallest curvature is located outside the first layer of glass 2.

The meaning is as follows: for any point on the arc surface, connecting lines are arranged along all directions around the arc surface, included angles between the connecting lines and the surface of the first layer of glass 2 are different, the circle center positions of arc lines formed along the arc surface are different, and the curvature radiuses of the arc lines are also different. In the present embodiment, the shape of the arc surface 1, in particular the shape of the arc surface relative to the first layer of glass itself, is designed, specifically: for each point on the arc 1, the center of the arc having the smallest curvature passing through the point along the arc 1 is located outside the first glass layer 2. In fact, in general, the plane formed by the arc with the smallest curvature of this arc and its center is perpendicular to the surface of the first glass layer. The radius of curvature of the arc is typically not less than 2.5mm during actual processing, and thus, in this embodiment, the thickness L1 of the first glass layer 2 is required to be not more than 2.5 mm. In general, the thickness L1 of the first glass layer 2 of the present embodiment is designed to be 1.6-2.0mm, and L1 is preferably 1.6 mm or 1.8mm or 2.0 mm. The above parameters do not take into account machining errors, that is, the actual product is allowed to have machining errors based on the above parameters.

The automobile inner rear-view mirror lens made of the front glass is shown in figure 1, and comprises front glass, rear glass 3, a conductive layer and an electrochromic material layer 4, wherein the conductive layer and the electrochromic material layer are arranged between the front glass and the rear glass, the front glass (a first layer of glass 2) and the rear glass 3 are respectively arranged on the front side and the rear side of the lens, the first conductive layer, the electrochromic material layer, a second conductive layer and a reflecting layer are sequentially arranged from the rear surface of the front glass to the front surface of the rear glass 3, the edges of the first conductive layer, the electrochromic material layer and the second conductive layer are blocked by a rubber frame 5 between the front glass and the rear glass, and the part is the prior art and is not repeated. In this embodiment, the rear glass 3 is a plate glass having a thickness L2 of 1.6 to 2.0mm, and preferably a plate glass having a thickness L2 of 1.6 mm, 1.8mm or 2.0 mm.

An automobile interior rear-view mirror can further be manufactured using the front glass or lens described in the present embodiment. Except for the front glass of the embodiment and the lens made of the front glass, other parts of the automobile interior rearview mirror adopt the prior art, and are not described in detail herein.
