[0002] Traditional sun visors usually need to be manually adjusted in angle or position to adapt to different light intensities. However, during driving, manual adjustment may distract the driver's attention and pose a safety hazard. Content of the Utility Model
[0003] Based on this, it is necessary to provide a sun visor that changes with the light intensity in view of the above technical problems.
[0004] To solve the above technical problems, the utility model adopts the following technical solutions:
[0005] A sun visor that changes with the light intensity, characterized in that the sun visor that changes with the light intensity includes a main sunshade unit and a sub-sunshade unit, and the sub-sunshade unit is telescopically arranged in the main sunshade unit.
[0006] The main sunshade unit includes a plate-shaped main sunshade single substrate. At the top of the main sunshade single substrate, there is a main fixing hook and a sub-fixing hook. In the middle of the main sunshade single substrate, there is a main electrochromic glass. Inside the main sunshade single substrate, there is a movable cavity. Inside the movable cavity, there are a pair of first driving motors. At the four corners on the inner side of the main sunshade single substrate, there is a first light sensor respectively. At the four corners on the outer side of the main sunshade single substrate, there is a second light sensor respectively. On the side wall of the main sunshade single substrate, there is a side mounting notch, and inside the side mounting notch, there is a second driving motor.
[0007] The sub-sunshade unit includes a plate-shaped sub-sunshade substrate. In the middle of the sub-sunshade substrate, there is a sub-electrochromic glass. At the inner edges of the sub-sunshade substrate, there are sub-driving racks respectively. On the sub-driving racks, there is a through positioning card slot. On the side of the sub-sunshade substrate, there is a driving tooth groove.
[0008] As a preferred embodiment of the utility model, the driving tooth groove cooperates with the second driving motor, and the sub-driving rack cooperates with the first driving motor.

Detailed implementation manners
[0027] In order to enable those skilled in the art of this technology to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0028] As Figure 1 and Figure 2 shown, the sunshade panel that varies with light intensity includes a main sunshade unit 1 and a secondary sunshade unit 2, and the secondary sunshade unit 2 is telescopically arranged inside the main sunshade unit 1.
[0029] As Figures 3 to 7 shown, the main sunshade unit 1 includes a plate-shaped main sunshade single substrate 11. At the top of the main sunshade single substrate 11, there is a main fixing hook 12 and a secondary fixing hook 13. In the middle of the main sunshade single substrate 11, there is a main color-changing glass 14. Inside the main sunshade single substrate 11, there is a movable cavity 111. Inside the movable cavity 111, there are a pair of first driving motors 1111. At the four inner corners of the main sunshade single substrate 11, there is a first light sensor 15 each. At the four outer corners of the main sunshade single substrate 11, there is a second light sensor 17 each. On the side wall of the main sunshade single substrate 11, there is a side mounting notch 16, and inside the side mounting notch 16, there is a second driving motor 161.
[0030] In addition, a handle hole 231 is provided at the bottom of the main sunshade single substrate 11.
[0031] As Figure 8 and Figure 9 shown, the secondary sunshade unit 2 includes a plate-shaped secondary sunshade substrate 21. A secondary electrochromic glass 23 is provided in the middle of the secondary sunshade substrate 21. Secondary drive racks 22 are provided at the inner edges of the secondary sunshade substrate 21. The secondary drive racks 22 cooperate with the first drive motor 1111. A through positioning card slot 221 is provided on the secondary drive rack 22. A drive tooth groove 222 is provided on the side of the secondary sunshade substrate 21. The drive tooth groove 222 cooperates with the second drive motor 161.
[0032] It should be noted that both the main electrochromic glass 14 and the secondary electrochromic glass 23 are electrochromic glasses.
[0033] The working mode of the sunshade plate that changes with the light intensity will be described below.
[0034] As Figure 10 shown, by using the second light sensors 17 at the four corners on the outer side of the main sunshade single substrate 11, the light intensity of the current front windshield can be sensed, so as to automatically adjust the color-changing effects of the main electrochromic glass 14 and the secondary electrochromic glass 23, and thus automatically adjust the sunshading effect of the sunshade plate. At the same time, as the light intensity changes, the first drive motor 1111 directly drives the secondary drive rack 22 of the secondary sunshade unit 2, so that the secondary sunshade unit 2 extends out of or retracts into the movable cavity 111, automatically blocking strong light.
[0035] As Figure 11 and Figure 12 shown, when the user rotates the main fixing hook 12 along the direction S to the left glass, the user can snap the secondary sunshade unit 2 into the side mounting notch 16. At this time, the positioning card slot 221 catches the opening of the side mounting notch 16. By using the first light sensors 15 at the four corners on the inner side of the main sunshade single substrate 11, the light of the left glass can be sensed, so as to automatically adjust the color-changing effects of the main electrochromic glass 14 and the secondary electrochromic glass 23, and thus automatically adjust the sunshading effect of the sunshade plate. At the same time, as the light intensity changes, the second drive motor 161 directly drives the drive tooth groove 222, so that the secondary sunshade unit 2 automatically rises and falls, automatically blocking strong light.
[0036] This automatic strong light blocking structure is novel, can play an automatic sunshading effect in different working modes, and has strong practicability.
[0037] Obviously, the embodiments described above are only a part of the embodiments of the present application, rather than all the embodiments. The preferred embodiments of the present application are shown in the drawings, but do not limit the patent scope of the present application.
