AI Technical Summary
The reflective surface of the existing electric anti-glare inner rearview mirror is a flat mirror, which causes the driver's rear view width to be limited. Especially when the body is too long, the field of view will be blocked by the back of the car body, affecting the use effect.
Convex lenses and electrochromic electrolytes are used to adopt convex lenses, and the reflective surface range of the convex lenses is larger than that of the flat mirrors. The divergence effect of the reflective surface is used to expand the field of view, and the electrochromic electrolytes are discolored after being powered on, absorbing strong light, reducing reflectivity, and achieving anti-glare function.
It effectively improves the driver's lack of rear view, expands the field of view through the design of convex lenses, and achieves an effective anti-glare effect through the use of electrochromic electrolyte.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile parts, and in particular relates to a novel electric anti-glare interior rearview mirror. Background Art
[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.
[0003] The car interior rearview mirror is a car component used to observe the situation inside the car and the vehicles behind the window. When driving at night, if the vehicle behind is driving with high beams on for a long time, the dazzling light will be reflected into the driver's eyes through the interior rearview mirror; therefore, the car interior rearview mirror needs to have an anti-glare function; it can be simply divided into manual anti-glare and electric anti-glare interior rearview mirrors according to different usage methods.
[0004] Among them, the manual anti-glare rearview mirror uses a knob on the mirror to adjust the lens angle to achieve the anti-glare function, suppressing glare through optical principles. The electric anti-glare rearview mirror has a photosensitive diode installed behind the mirror. When the diode senses strong light, the control circuit will apply voltage to the ionosphere of the mirror. Under the action of the voltage, the lens will darken to achieve the purpose of anti-glare.
[0005] However, at present, the reflective surfaces of the lenses of the above two anti-glare interior mirrors are both plane mirrors, which are made by injecting a color-changing electrolyte in the middle of two ordinary plane lenses, and the reflective area is a plane effect. The plane mirror has certain restrictions on the width of the driver's rear field of view; for example, the body length of an existing 7-seater car is longer than that of a 5-seater car, and the rear field of view is worse than that of a 5-seater car. Therefore, when the body is too long, the driver's rear field of view will be blocked by the rear guard plate of the car, which will cause the width of the field of view to become smaller and affect the use effect.

DETAILED DESCRIPTION
[0030] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0031] Embodiment 1
[0032] like Figure 1 As shown, the utility model proposes a novel electric anti-glare interior rearview mirror, comprising: a housing 6 and a convex lens 2 embedded in the housing;
[0033] A circuit integrated component 4 is provided in the housing 6, a positive electrode 203 and a negative electrode 204 are provided on both sides of the convex lens 2, and the circuit integrated component 4 is connected to the positive electrode 203 and the negative electrode 204 respectively;
[0034] like Figure 2 As shown, the convex lens 2 includes a front lens 201 and a rear lens 202 that are adjacent to each other, with a gap between the front lens 201 and the rear lens 202, and an electrochromic electrolyte is injected into the gap.
[0035] The utility model manufactures two convex mirrors into convex electrochromic lenses, and finally produces and assembles them into a convex electric anti-glare interior rearview mirror. The characteristic that the range of the reflection surface is larger than that of the plane mirror is utilized, and the convex mirror lens has the effect of diverging light, so as to solve the problem that the driver's rear field of vision is small due to the length of the vehicle body. At the same time, electrochromic electrolyte is injected into the convex lens, and the electrochromic electrolyte changes from transparent to dark green after power is turned on, so that a large part of the strong light irradiated from the rear will be absorbed by the mirror surface, thereby effectively reducing the reflectivity and realizing the anti-glare function.
[0036] Furthermore, the convex surface of the rear lens 202 is arranged opposite to the concave surface of the front lens 201, the convex surface of the rear lens 202 is provided with a reflective coating, the concave surface of the rear lens 202 is provided with a shock-absorbing component 3, and the convex surface of the front lens 201 is the light-facing surface of the interior rearview mirror; the periphery of the convex lens 2 is coated with a sealant for sealing the gap at the edge of the front lens 201 and the rear lens 202.
[0037] In this embodiment, the front lens 201 and the rear lens 202 have the same specifications and parameters, and are assembled after being polished and other processes, and the periphery of the glass sheets is sealed with glue. A reflective coating layer is added to the surface of the rear lens 202, and the reflective coating layer is used to enhance the reflectivity and clarity of the mirror surface.
[0038] The reflective coating layer and the electrochromic electrolyte of this embodiment can be made of any appropriate material disclosed in the prior art, which will not be described in detail here.
[0039] Further, such as Figure 3 As shown in (a) and (b), the shock absorbing assembly 3 includes a first shock absorbing sponge 301 and a second shock absorbing sponge 302. The first shock absorbing sponge 301 is a long strip structure, which is evenly arranged around the side of the convex lens facing the shell. The second shock absorbing sponge 302 is a rectangular block structure, which is arranged in the middle of the side of the convex lens facing the shell.
[0040] In this embodiment, a protective shock-absorbing component 3 is arranged on the back side of the convex lens 2. The first shock-absorbing sponge 301 is composed of 6 1 mm thick rectangular sponge blocks with glue, which are evenly attached to the back and around the convex lens 2 to play a shock-absorbing and protective role; auxiliary shock-absorbing sponges 302 are arranged on both sides of the shock-absorbing sponge 301. The shock-absorbing sponge 302 is composed of two identical 8.5 mm thick rectangular blocks with glue.
[0041] Furthermore, a ball and socket assembly 5 is provided at the middle position of the interior of the shell 6, and a support rod assembly 7 is provided at the middle position of the exterior of the shell 6. The ball and socket assembly 5 and the support rod assembly 7 are assembled by pressure tooling; the other end of the support rod assembly 7 is fixedly arranged inside the vehicle.
[0042] Specifically: On the left side of the housing 6 is a circuit integration group 4 fastened by two screws, and in the middle of the housing 6 is a ball and socket assembly 5 fastened by four screws. The ball and socket assembly 5 and the support rod assembly 7 are assembled together by a pressure tooling.
[0043] like Figure 4 As shown, the support rod group 7 includes a support rod 701 and a wiring harness 702. One end of the wiring harness 702 is fixed to the inside of the support rod 701 by a clip, and the other end passes through the support rod 701 to be connected to the corresponding interface of the line integrated component 4; another interface of the wiring harness integrated component 4 is connected to the positive electrode 203 and the negative electrode 204 of the convex lens 2.
[0044] Furthermore, it also includes a mirror frame 1 snap-fitted into the shell, a convex lens 2 is embedded in the mirror frame 1, and the mirror frame 1 and the shell 6 are snap-fitted and assembled by auxiliary tooling to complete the assembly of the interior rearview mirror.
[0045] Further, such as Figure 5 As shown, light sensors are respectively arranged on the front and rear sides of the housing 6; the light sensors are connected to the circuit integration component 4 through a wiring harness. The circuit integration component 4 includes a controller and a photosensitive element, the controller is connected to the photosensitive element, and the photosensitive element is connected to the light sensor.
[0046] In this embodiment, the convex electric anti-glare interior rearview mirror is installed on the vehicle. When the power is off, the electrochromic electrolyte is transparent and in a high reflectivity state. After the power is turned on, the front photoreceptor absorbs the light behind the driver, and the rear photoreceptor absorbs the light in front of the driver.
[0047] The light signals collected by the front and rear photo sensors are input into the photosensitive elements of the circuit integrated components and analyzed by the controller. When the difference in light brightness between the rear photo sensor and the front photo sensor exceeds the set anti-glare standard, the convex lens is energized to change the electrochromic electrolyte from transparent to dark green. In this way, a large part of the strong light from behind will be absorbed by the mirror surface, thereby effectively reducing the reflectivity and completing the anti-glare function (anti-glare is not activated in reversing mode).
[0048] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
