Technical Field

[0001] The present invention relates to the technical field related to automobile screen displays, and in particular to an anti-reflective automobile screen display. Background Art

[0002] During car driving, the screen display is a key device that provides various important information, such as navigation instructions, vehicle status monitoring data, etc. However, due to the changeable operating environment of the car, screen reflection is very common. When sunlight, street lights or other external light sources shine on the screen, the reflection will make the screen content difficult to see clearly. For this reason, an anti-reflective car screen display is particularly needed.

[0003] Due to the traditional physical shading method of existing car screen displays, although it can reduce screen reflection to a certain extent, it has the problem of poor flexibility and cannot be adjusted according to changes in light and the actual needs of the driver. Most car screens require manual brightness adjustment, and ordinary brightness adjustment cannot fundamentally solve the reflection problem.

[0004] In view of the above problems, an anti-reflective automobile screen display is proposed. Summary of the invention

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-reflective automobile screen display, comprising a display body, one end of the display body is provided with a shading structure, the other end of the display body is provided with a dimming structure, the bottom of the display body is provided with a base, and the base is connected to the display body in a positioning and rotatable manner;

[0007] The shading structure includes a shading curtain installed at one end of the display body, a shaft column is passed through the beginning of the shading curtain, flexible rods are provided at both ends of the shaft column, a limit bolt is provided on the inner wall of the flexible rod, and the limit bolt is slidably connected to the flexible rod, a mounting column is provided on the bottom wall of the flexible rod, and a limit hole is provided at one end of the mounting column;

[0010] Preferably, the curtain box is arranged between two groups of flexible rods, and the shading curtain is rolled up on the inner wall of the curtain box and is rotatably connected to the curtain box at the inner wall of the curtain box.

[0011] Preferably, one end of the flexible rod connected to the shaft column is a flexible bending structure, and one end of the flexible rod installed on the inner wall of the mounting column is slidably connected to the mounting column.

[0012] Preferably, the limiting bolt is passed through the limiting hole, and the limiting holes are arranged in groups in parallel.

[0013] Preferably, the dimming structure includes a conductive layer coated on one end of the display body, an electrochromic layer coated on one end of the conductive layer, a protective layer coated on one end of the electrochromic layer, and an anti-fingerprint layer coated on one end of the protective layer.

[0014] Preferably, a light sensor is provided on the top of the display body, and the exterior of the light sensor is made of black plastic material to reduce the influence of self-reflection on detection.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The anti-reflective car screen display is provided with a shading structure. The shading curtain in the shading structure is convenient for flexibly adjusting the unfolded area and position according to the incident angle of light. Through the cooperation of the shaft column, the flexible rod and the limit bolt and other components, it can prevent light from directly irradiating the screen and generating reflections, and is suitable for use in strong light.

[0020] The electrochromic layer in the dimming structure automatically adjusts according to the light intensity monitored by the light sensor. When the external light is strong, the electrochromic layer changes its own optical properties, reduces the amount of light that passes through the coating and shines on the screen, and reduces reflections from the perspective of the screen itself. The light sensor uses black material as the outer shell, which reduces the impact of its own reflections on the detection results. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] Example

[0031] like Figure 1-5 As shown, it includes a display body 1, a shading structure 2 is provided at one end of the display body 1, a dimming structure 3 is provided at the other end of the display body 1, a base 4 is provided at the bottom of the display body 1, and the base 4 is connected to the display body 1 for positioning and rotation, the shading structure 2 includes a shading curtain 201 installed at one end of the display body 1, a shaft column 202 is passed through the starting end of the shading curtain 201, flexible rods 203 are provided at both ends of the shaft column 202, a limiting bolt 204 is provided on the inner wall of the flexible rod 203, and the limiting bolt 204 is slidably connected to the flexible rod 203, a mounting column 205 is provided on the bottom wall of the flexible rod 203, and a limiting hole 206 is opened at one end of the mounting column 205.

[0032] It should be noted that, in the present embodiment, when shading is required, firstly, the two groups of limit bolts 204 are pressed, so that the two groups of limit bolts 204 are received in the installation column 205, and then the flexible rod 203 is slightly rotated to misalign the limit bolts 204 with the limit holes 206, and then the flexible rod 203 is rotated to the limit bolts 204 after adjusting to a suitable height as required until the limit bolts 204 are embedded in the limit holes 206. In this process, the flexible rod 203 drives the shaft column 202 to move, and the shaft column 202 drives the shading curtain 201 to move and pull the shading curtain 201 out of the curtain box 207. Finally, the bending angle of the upper end of the flexible rod 203 is adjusted according to the light angle to achieve sunshade, which can be used when the light is strong to enhance the visibility of the screen.

[0033] Among them, when shading is not needed, the limit bolt 204 is retracted into the installation column 205 and the flexible rod 203 is slightly rotated, the flexible rod 203 is pushed downward to retract into the installation column 205, and then the limit bolt 204 is aligned with the limit hole 206. Since a clockwork spring device is installed inside the curtain box 207, when the flexible rod 203 is retracted, the shading curtain 201 is rolled into the curtain box 207. Furthermore, the mounting seat 208 is used to install the mounting column 205 at one end of the display body 1.

[0034] like Figure 6-7 As shown, the dimming structure 3 includes a conductive layer 301 coated on one end of the display body 1, an electrochromic layer 302 is coated on one end of the conductive layer 301, a protective layer 303 is coated on one end of the electrochromic layer 302, and an anti-fingerprint layer 304 is coated on one end of the protective layer 303.

[0035] It should be noted that, in the present embodiment, when the light sensor 305 detects a change in light, the on-board computer determines whether dimming is required based on the light sensor 305 signal. If necessary, since fine metal wires are welded at the edge of the conductive layer 301, these wires are connected to the control circuit of the on-board computer system to realize the input and output of current. The on-board computer outputs a suitable current to the conductive layer 301, and the conductive layer 301 transmits the current to the electrochromic layer 302. The electrochromic layer 302 changes the optical properties to achieve automatic dimming. The protective layer is made of a highly transparent silicone resin material with high transparency, which is convenient for reducing the refraction and reflection of light on the coating surface. The thickness of the transparent protective coating 303 is about 200-300 nanometers, and it is evenly covered on the electrochromic layer 302 through a spin coating process. On the surface of the protective layer 303, an anti-fingerprint layer 304 is also provided, so that stains such as fingerprints are not easily attached to the coating surface, further maintaining the cleanliness and visibility of the screen.

[0036] Working principle of the present invention:

[0037] Refer to the instruction manual Figure 1-5First, when the light sensor 305 detects a change in light, the onboard computer determines whether dimming is required based on the light sensor 305 signal. If necessary, since fine metal wires are welded at the edge of the conductive layer 301, these wires are connected to the control circuit of the onboard computer system to realize the input and output of current. The onboard computer outputs a suitable current to the conductive layer 301, and the conductive layer 301 transmits the current to the electrochromic layer 302. The electrochromic layer 302 changes the optical properties to achieve automatic dimming. The protective layer is made of a highly transparent organic silicone resin material with high transparency, which is convenient for reducing the refraction and reflection of light on the coating surface. The thickness of the transparent protective coating 303 is about 200-300 nanometers, and it is evenly covered on the electrochromic layer 302 through a spin coating process. On the surface of the protective layer 303, an anti-fingerprint layer 304 is also provided, so that fingerprints and other stains are not easy to adhere to the coating surface, further maintaining the cleanliness and visibility of the screen;

[0038] When encountering strong light, press the two groups of limit bolts 204 so that the two groups of limit bolts 204 are retracted into the installation column 205, and then slightly rotate the flexible rod 203 to misalign the limit bolts 204 with the limit holes 206. Then, after adjusting to a suitable height as needed, rotate the flexible rod 203 until the limit bolts 204 are embedded in the limit holes 206. In this process, the flexible rod 203 drives the shaft column 202 to move, and the shaft column 202 drives the shading curtain 201 to move and pull the shading curtain 201 out of the curtain box 207. Finally, adjust the bending angle of the upper end of the flexible rod 203 according to the light angle to achieve sunlight shielding and enhance the visibility of the screen.

[0039] Among them, when shading is not needed, the limit bolt 204 is retracted into the installation column 205 and the flexible rod 203 is slightly rotated, the flexible rod 203 is pushed downward to retract into the installation column 205, and then the limit bolt 204 is aligned with the limit hole 206. Since a clockwork spring device is installed inside the curtain box 207, when the flexible rod 203 is retracted, the shading curtain 201 is rolled into the curtain box 207. Furthermore, the mounting seat 208 is used to install the mounting column 205 at one end of the display body 1.
