Technical Field

[0001] The present invention relates to the technical field of dimming films, and in particular to a dimming film utilizing electrochromic technology. Background Art

[0002] Electrochromic dimming film uses liquid crystal to change the color of the film. The color of the film changes by supplying power to the liquid crystal. However, due to the poor rigidity of the film itself, it is easy to squeeze the liquid crystal inside when subjected to external force. When the liquid crystal is subjected to external mechanical force during operation, it will deflect and cause the squeezed part to change color. Therefore, the existing color-changing dimming film is not stable after color change and will be disturbed by external forces. Summary of the Invention

[0003] The object of the present invention is to provide a light-adjusting film using electrochromic technology to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dimming film utilizing electrochromic technology, comprising a thin film transparent base, an internal accommodating groove, a connecting line groove, a liquid crystal color-changing bead, a liquid crystal injection cavity and a liquid crystal supply pressure line, wherein the interior of the thin film transparent base is provided with an internal accommodating groove, and the internal accommodating grooves are evenly distributed in a rectangular array, the connecting line grooves are provided inside the thin film transparent base, and the connecting line grooves pass through the internal accommodating grooves, the interior of the internal accommodating grooves is fixedly provided with liquid crystal color-changing beads, the interior of the liquid crystal color-changing bead is provided with a liquid crystal injection cavity, the liquid crystal injection cavity is supplied with power and connected through the liquid crystal supply pressure line, and the liquid crystal supply pressure line is interspersed inside the connecting line grooves.

[0005] The liquid crystal color-changing bead is composed of an upper arc convex portion, a glass base and a lower arc convex portion.

[0007] The upper end of the glass base is fixedly mounted to the upper arc convex, and the lower end is fixedly mounted to the lower arc convex. The liquid crystal injection cavity is opened inside the glass base. The liquid crystal injection cavity is a cylindrical cavity, and the interior of the liquid crystal injection cavity is filled with liquid crystal.

[0008] An adhesive layer is fixedly attached to the lower surface of the thin film transparent base, and a protective coating layer is attached to the lower surface of the adhesive layer.

[0009] A hard wear-resistant layer is fixedly attached to the upper surface of the thin film transparent base, and a lens flange is fixedly provided on the surface of the hard wear-resistant layer. The lens flange is semi-convex lens-shaped and evenly distributed in a rectangular array. The lens flange corresponds coaxially to the liquid crystal color-changing beads.

[0010] A connection slot is provided on the surface of the glass base, the connection slot is communicated with the liquid crystal injection cavity, and the end of the liquid crystal pressure supply line is sealed and inserted into the connection slot.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention utilizes a dimming film using electrochromic technology, which can electrically change the color of the film through the provided liquid crystal color-changing beads. At the same time, the film has stable properties and the advantage of being pressure-resistant. When squeezed by external force, it will not cause oppression to the liquid crystal, and thus will not cause the liquid crystal to deflect and change color due to mechanical pressure, making the film more stable after color adjustment.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 5The present invention provides a technical solution: a dimming film using electrochromic technology, including a thin film transparent base 1, an internal accommodating groove 2, a connecting groove 3, a liquid crystal color-changing bead 4, a liquid crystal injection cavity 5 and a liquid crystal supply pressure line 6. The internal accommodating groove 2 is opened inside the thin film transparent base 1, and the internal accommodating groove 2 is evenly distributed in a rectangular array. The connecting groove 3 is opened inside the thin film transparent base 1, and the connecting groove 3 penetrates and connects the internal accommodating groove 2. The liquid crystal color-changing bead 4 is fixedly arranged inside the internal accommodating groove 2. The liquid crystal color-changing bead 4 is opened inside the liquid crystal injection cavity 5. The liquid crystal injection cavity 5 is powered and connected through the liquid crystal supply pressure line 6, and the liquid crystal supply pressure line 6 is inserted inside the connecting groove 3.

[0021] The liquid crystal color-changing bead 4 is composed of an upper arc 401, a glass base 402 and a lower arc 403. The upper arc 401, the glass base 402 and the lower arc 403 are made of the same material, and are all made of glass in one piece. They have pressure resistance and can protect the liquid crystal inside.

[0022] The upper arc 401 and the lower arc 403 have the same shape, both are semi-convex lenses, and the two are symmetrically arranged up and down. The glass base 402 is cylindrical. The upper end of the glass base 402 is fixedly installed with the upper arc 401, and the lower end is fixedly installed with the lower arc 403. The liquid crystal injection cavity 5 is opened inside the glass base 402. The liquid crystal injection cavity 5 is a cylindrical cavity, and the interior of the liquid crystal injection cavity 5 is filled with liquid crystal.

[0023] An adhesive layer 101 is fixedly attached to the lower surface of the thin film transparent base 1 , and a protective coating layer 102 is attached to the lower surface of the adhesive layer 101 .

[0024] A hard wear-resistant layer 103 is fixedly attached to the upper surface of the thin film transparent base 1, and a lens flange 104 is fixedly provided on the surface of the hard wear-resistant layer 103. The lens flange 104 is semi-convex and evenly distributed in a rectangular array. The lens flange 104 corresponds coaxially with the liquid crystal color-changing beads 4. Figure 2 As shown in .

[0025] A connecting slot 404 is provided on the surface of the glass base 402 . The connecting slot 404 is communicated with the liquid crystal injection cavity 5 . The end of the liquid crystal supply pressure line 6 is sealed and inserted into the connecting slot 404 .

[0026] The present invention pressurizes and colors the liquid crystal inside the liquid crystal injection cavity 5 through the liquid crystal pressure supply line 6, causing the film to change color, thereby achieving a color adjustment effect. When the film is subjected to external mechanical force, since the liquid crystal color-changing beads 4 are made of glass, they are not easily deformed, thereby avoiding squeezing of the liquid crystal inside the liquid crystal injection cavity 5, so that the liquid crystal has a stable working environment. By utilizing the convex lens principle of the lens flange 104, the color display point of the liquid crystal color-changing beads 4 can be magnified, thereby improving the color display effect viewed from a distance.

[0027] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
