Description

Technical Field

[0001] The utility model relates to the technical field of photochromic glass, in particular to a photochromic glass with adjustable color change degree. Background Art

[0002] Photochromic glass is a functional glass that combines the advantages of dimming, energy saving, and decoration. When exposed to chromic light such as ultraviolet rays or short-wavelength visible light, the glass's light transmittance is reduced or its color changes, and it can automatically return to its original transparent state after the chromic light stops. Compared with traditional Low-E glass (also known as low-emissivity glass), photochromic glass has an adjustable light transmittance, which can take into account different light transmittance requirements during the day and night. Compared with electro-photochromic glass, photochromic glass has a simple structure, strong processing and expansion capabilities, and significant cost advantages. Applying photochromic glass to scenes such as buildings and car sunroofs can shield excessive light radiation under strong light, reduce the intake of dazzling glare, and reduce the use of air conditioning to a certain extent; in a weak light environment, it maintains a good field of vision and transparency, so that the glass can give full play to its original viewing function.

[0003] However, under the same environmental conditions, different people and different working conditions have different requirements for light parameters, and therefore have different requirements for the degree of discoloration of photochromic glass. The existing photochromic glass windows have a simple structure, and the discoloration effect is only related to environmental conditions. They cannot be freely adjusted according to human subjective initiative, and have poor adaptability, which has become a key factor restricting its industrial promotion. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The present invention provides a photochromic glass with adjustable color change degree, such as Figure 3 As shown, it includes an inner glass 1, an outer glass 2, a frame 3, a photochromic glass body 4, a driving mechanism 9 and a fixed rail clamping mechanism 10. A cavity 5 is formed between the inner glass 1 and the outer glass 2. In this embodiment, the inner glass 1 and the outer glass 2 are both ultra-clear glass with a thickness of 6 mm, and the thickness of the cavity 5 is 12 mm. Figure 1 As shown, the cavity 5 is sealed by the frame 3, and the photochromic glass body 4 is attached to the side of the inner glass 1 away from the outer glass 2, as shown in FIG. Figure 2 As shown, the photochromic glass composed of inner glass 1, outer glass 2, frame 3 and photochromic glass body 4 has a light-transmitting area 6 in the middle and an opaque area 11 at the edge. The light-transmitting area 6 is used for lighting. The driving mechanism 9 and the fixed rail clamping mechanism 10 are arranged in the opaque area 11. In this embodiment, the photochromic glass body 4 is a silver halide photochromic glass, or a laminated photochromic glass containing a photochromic film, or a common glass coated with a photochromic material, which can produce color changes under ultraviolet irradiation, such as Figure 1 As shown, a high-transmittance film layer 7 is laid in the cavity 5. Figure 5 As shown, the high-transmittance film layer 7 has N areas 8 of the same size arranged in this way, the size of each area 8 is the same as the size of the light-transmitting area 6, the first area 8 does not contain ultraviolet light shielding material, the content of ultraviolet light shielding material in the second to Nth areas 8 increases successively, and the ultraviolet light shielding material in each area 8 is evenly distributed; when the high-transmittance film layer 7 in the cavity 5 is switched to different areas 8, the high-transmittance film layer 7 has different shielding amounts for ultraviolet rays, that is, different amounts of ultraviolet rays irradiated onto the photochromic glass body 4, resulting in different degrees of discoloration of the photochromic glass body 4, thereby achieving the purpose of being able to artificially control the degree of discoloration.

[0025] In order to be able to autonomously switch the region 8 of the high-transmittance film layer 7 in the cavity 5, as Figure 1 As shown, a driving mechanism 9 is respectively arranged on two opposite sides along the length direction of the high-transmittance film layer 7 in the frame 3, and the high-transmittance film layer 7 is transmission-connected between the two driving mechanisms 9. The two driving mechanisms 9 are used to roll up the high-transmittance film layer 7 so that the N regions 8 of the high-transmittance film layer 7 can be switched in the cavity 5 accordingly. The switching of the regions 8 of the high-transmittance film layer 7 in the cavity 5 is completed by synchronously starting the two driving mechanisms 9.

[0026] Specifically, Figure 2 As shown, the driving mechanism 9 includes a motor 91 and a rotating shaft 92. The motor 91 is fixedly arranged on the inner wall of the frame 3. The rotating shaft 92 is fixedly connected to the output shaft of the motor 91. The high-transmittance film layer 7 is rolled up on the rotating shaft 92. The motor 91 is controlled to rotate to drive the rotating shaft 92 to rotate. The rotating shaft 92 drives the high-transmittance film layer 7 to roll up, so that the area 8 of the high-transmittance film layer 7 in the cavity 5 can be switched to achieve the purpose of autonomous adjustment.

[0027] Furthermore, the driving mechanism 9 further includes a controller and a mobile control terminal, which are not shown in the figure. The controller is electrically connected to the motor 91, and the mobile control terminal is wirelessly connected to the controller. People can remotely control the start and stop of the motor 91 through the mobile control terminal, which is convenient for switching the high-transmittance film layer 7. Figure 3 As shown, a through hole 31 is opened on the frame 3 , and the controller is connected to an external power line through the through hole 31 , and the through hole 31 is sealed around to ensure the sealing of the cavity 5 .

[0028] like Figure 2 As shown, in one embodiment, a fixed rail clamping mechanism 10 is respectively provided on two opposite sides along the width direction of the high-transmittance film layer 7 in the frame 3, and the two fixed rail clamping mechanisms 10 are used to tension the high-transmittance film layer 7 in the frame 3 so that the high-transmittance film layer 7 is parallel to the photochromic glass body 4.

[0029] Specifically, Figure 4 As shown, the fixed rail clamping mechanism 10 includes a plurality of groups of clips 101, and the plurality of groups of clips 101 are evenly arranged on the inner wall of the frame 3. The clip 101 includes two bearings 1011 and two clamping columns 1012, the two bearings 1011 are arranged in parallel on the inner wall of the frame 3, the two clamping columns 1012 are respectively fixedly inserted in the corresponding bearings 1011, and a clamping space for clamping the high-transmittance film layer 7 is formed between the two clamping columns 1012. When the driving mechanism 9 switches the high-transmittance film layer 7, the high-transmittance film layer 7 slides in the clamping space, and the two clamping columns 1012 always roll and fit on both sides of the edge of the high-transmittance film layer 7, so that the high-transmittance film layer 7 is in a tensioned state and parallel to the photochromic glass body 4.

[0030] The working principle of this utility model:

[0031] People start the motor 91 by moving the control terminal, and the motor 91 drives the rotating shaft 92 to rotate. With the cooperation of the two rotating shafts 92, the high-transmittance film layer 7 is driven to roll up, so that the area 8 of the high-transmittance film layer 7 in the cavity 5 can be switched. According to subjective needs, it is switched to different areas 8 of the high-transmittance film layer 7, so that the photochromic glass body 4 is adjusted to a suitable color change degree, so that the color change degree of the photochromic glass body 4 can be independently adjusted according to personal needs.
