After high-temperature and high-pressure encapsulation processing, laminated glass is formed. However, in the related art, during the encapsulation process, small molecules in the adhesive film will invade the liquid crystal layer of the dimming film sheet under high temperature and high pressure, causing the edge dimming function of the dimming film sheet to fail, and as the use time increases, the small molecules will continuously erode the liquid crystal layer, causing the dimming function of the entire dimming film sheet to fail.

[0044] Considering that in the packaging process of the existing dimming glass, small molecules in the adhesive film under high temperature and high pressure will invade the liquid crystal layer of the dimming film, causing the edge dimming function of the dimming film to fail, and as the use time increases, the small molecules will continue to erode the liquid crystal layer, causing the dimming function of the entire dimming film to fail. The present application provides a dimming glass 1, a dimming glass manufacturing method and a vehicle.

[0045] Specifically, please refer to the accompanying drawings Figure 1 One embodiment of the present application provides a dimming glass 1, which can include a first glass cover plate 10, a first intermediate layer 20, a dimming film 30, an edge sealing strip 40, a second intermediate layer 50, a second glass cover plate 60 and an edge repairing layer 70. The first intermediate layer 20 is stacked on the first glass cover plate 10. In combination Figure 2 As shown, the dimming film 30 includes a film body 31 and a bending structure 32 connected to each other, the film body 31 is stacked on the side of the first intermediate layer 20 away from the first glass cover plate 10, and the bending structure 32 is bent towards the side close to the first glass cover plate 10 relative to the film body 31 and abuts against the first glass cover plate 10. The edge sealing strip 40 includes a lapping portion 41 and an edge sealing portion 42 connected to each other, the lapping portion 41 abuts against the side of the bending structure 32 away from the first glass cover plate 10, and the edge sealing portion 42 extends towards the side close to the first glass cover plate 10 and abuts against the first glass cover plate 10. The second intermediate layer 50 is stacked on the side of the dimming film 30 away from the first intermediate layer 20. The second glass cover plate 60 is stacked on the side of the second intermediate layer 50 away from the dimming film 30. The edge repairing layer 70 is clamped between the first glass cover plate 10 and the second intermediate layer 50 along the edge of the dimming film 30.

[0046] It should be noted that the light-adjusting film 30 has a first substrate layer, a second substrate layer, and a liquid crystal layer, wherein the liquid crystal layer is sandwiched between the first substrate layer and the second substrate layer. Therefore, it is understandable that, in combination Figure 2 As shown in the figure, in the case that the light-adjusting film 30 is not subjected to the edge sealing treatment, the invasion path of the small molecules of the first intermediate layer 20, the second intermediate layer 50, and the edge sealing layer 70 is from the position of the liquid crystal layer end surface 30a of the light-adjusting film 30 to invade the liquid crystal layer.

[0047] The light-adjusting glass 1 of the present application first bends the bending structure 32 relative to the film body 31 towards the side close to the first glass cover plate 10 and abuts against the first glass cover plate 10, so that the small molecules of the first intermediate layer 20 cannot penetrate to the liquid crystal layer end surface 30a of the light-adjusting film 30; secondly, the lapping part 41 abuts against the side of the bending structure 32 away from the first glass cover plate 10, and the edge sealing part 42 extends towards the side close to the first glass cover plate 10 and abuts against the first glass cover plate 10, so that the small molecules of the second intermediate layer 50 and the edge sealing layer 70 cannot penetrate to the liquid crystal layer end surface 30a of the light-adjusting film 30, thereby being able to protect the light-adjusting film 30 from the invasion of the small molecules of the first intermediate layer 20, the second intermediate layer 50, and the edge sealing layer 70 during the packaging process in a high-temperature and high-pressure environment, and avoiding the problem of failure of the light-adjusting function of the light-adjusting film 30.

[0048] Optionally, the first intermediate layer 20 and the second intermediate layer 50 can be but are not limited to using materials such as PVB (Polyvinyl Butyral), EVA (Ethylene Vinyl Acetate Copolymer), or TPU (Thermoplastic Urethane).

[0049] Optionally, the edge sealing strip 40 can be but is not limited to using materials such as PET (Polyethylene terephthalate), PP (Polypropylene), or PE (Polyethylene).

[0050] Optionally, in combination Figure 2 As shown in the figure, in the vertical direction perpendicular to the plane of the first glass cover plate 10, the first glass cover plate 10, the second glass cover plate 60, the second intermediate layer 50, and the edge sealing layer 70 can be arranged in alignment, so as to improve the appearance of the light-adjusting glass 1 and ensure the mutual pressing effect of the first glass cover plate 10, the second glass cover plate 60, the second intermediate layer 50, and the edge sealing layer 70 at the edge position.

[0051] It should be noted that the edge filling layer 70 can be arranged between the first glass cover plate 10 and the second intermediate layer 50 to fill the gap between the first glass cover plate 10 and the second intermediate layer 50 by the edge filling layer 70, so as to improve the mutual pressing effect between the first glass cover plate 10, the first intermediate layer 20, the light control film 30, the second intermediate layer 50 and the second glass cover plate 60.

[0052] Preferably, in combination with Figure 3 As shown, the light control film 30 is parallel to the first intermediate layer 20 in the flattened state, and the light control film 30 protrudes the first intermediate layer 20 by a first preset width D1 on the plane where the light control film 30 and the first intermediate layer 20 are in contact with each other. In this way, by controlling the protruding width of the light control film 30 relative to the first intermediate layer 20, it can be ensured that the protruding part of the light control film 30 has sufficient area to contact the first glass cover plate 10 after the bending structure 32 is formed by bending, and at the same time, it can also be ensured that the bending structure 32 has sufficient area for the overlapping part 41 of the edge sealing strip 40 to overlap and seal, thereby improving the sealing effect of the bending structure 32.

[0053] More preferably, the first preset width D1 can be greater than or equal to 3mm, for example, the first preset width D1 can be 3mm, 4mm or 5mm, etc.

[0054] Preferably, the edge sealing strip 40 and the light control film 30 are parallel to each other in the flattened state, and the edge sealing strip 40 protrudes the light control film 30 by a second preset width D2 on the plane where the edge sealing strip 40 and the light control film 30 are in contact with each other. In this way, by controlling the protruding width of the edge sealing strip 40 relative to the light control film 30, it can be ensured that the edge sealing part 42 has sufficient area to abut on the first glass cover plate 10 after the edge sealing part 42 is formed by bending, thereby improving the sealing effect of the edge sealing part 42 on the light control film 30.

[0055] More preferably, the second preset width D2 can be greater than or equal to 3mm, for example, the second preset width D2 can be 3mm, 4mm or 5mm, etc.

[0056] Preferably, in combination with Figure 3 As shown, the cross-sectional thickness d of the edge sealing strip 40 can be less than or equal to 0.2mm, so that by controlling the thickness of the edge sealing strip 40, the problem of glass chipping caused by the excessive thickness of the edge sealing strip 40 can be prevented.

[0057] Specifically, during the mutual abutment of the edge sealing portion 42 and the first glass cover plate 10, the edge sealing portion 42 being too thick can generate a large concentrated stress, and then a glass splinter problem. Therefore, in this embodiment, by controlling the thickness of the edge sealing strip 40, the production yield and product quality of the dimming glass 1 are improved. In addition, controlling the thickness of the edge sealing strip 40 also helps to prevent the problem of unstable adsorption between the lap joint portion 41 and the dimming film sheet 30, and between the edge sealing portion 42 and the first glass cover plate 10 caused by the edge sealing strip 40 being too thick, so as to improve the edge sealing effect of the edge sealing strip 40 on the dimming film sheet 30.

[0058] Optionally, referring back to Figure 2 , the bending structure 32 can include a bending portion 321 and a first abutment portion 322, the bending portion 321 is connected to the film sheet body 31 and deviates from the film sheet body 31 towards the side close to the first glass cover plate 10, and extends at a preset angle, and the first abutment portion 322 is connected to the extending end of the bending portion 321 and abuts against the first glass cover plate 10.

[0059] Specifically, by deviating from the film sheet body 31 towards the side close to the first glass cover plate 10 and extending at a preset angle, the bending portion 321 can avoid the first intermediate layer 20 and smoothly extend to the first glass cover plate 10, and the first abutment portion 322 is connected. The structure arrangement is simple and reliable. According to the above-mentioned embodiments of the present application, the lap joint portion 41 can abut against the side of the first abutment portion 322 away from the first glass cover plate 10.

[0060] Optionally, continuing to refer to Figure 2 , the edge sealing portion 42 can include an extending portion 421 and a second abutment portion 422, one end of the extending portion 421 is connected to the lap joint portion 41, the other end of the extending portion 421 extends towards the side close to the first glass cover plate 10 and is connected to the second abutment portion 422, and the second abutment portion 422 abuts against the first glass cover plate 10, so as to realize the edge sealing of the dimming film sheet 30 by the edge sealing portion 42.

[0061] It is worth noting that, as shown in Figure 2 , the extending portion 421 can be attached to the liquid crystal layer end surface 30a of the dimming film sheet 30; in some other embodiments, the extending portion 421 can also not be attached to the liquid crystal layer end surface 30a of the dimming film sheet 30, so that a sealing gap can be formed between the extending portion 421 and the liquid crystal layer end surface 30a of the dimming film sheet 30, in which case the liquid crystal layer end surface 30a can also be sealed and protected by the edge sealing strip 40, ensuring that the liquid crystal layer of the dimming film sheet 30 is not invaded by the small molecules of the second intermediate layer 50 and the edge sealing layer 70.

[0062] Preferably, in combination with Figure 2As shown, the edge filling layer 70 can include a first edge filling strip 71 and a second edge filling strip 72, the first edge filling strip 71 is clamped between the first glass cover plate 10 and the second intermediate layer 50, and the second edge filling strip 72 is clamped between the bending structure 32 and the second intermediate layer 50, so that the first edge filling strip 71 and the second edge filling strip 72 are used to fill the edges of the light control glass 1 respectively, which helps to adapt to the gap shape of the first glass cover plate 10 and the second intermediate layer 50 at the edge position, and improves the edge filling effect.

[0063] Specifically, since the bending structure 32 has the first abutting portion 322, a stepped gap with different thicknesses will be formed between the first glass cover plate 10 and the second intermediate layer 50 due to the thickness of the first abutting portion 322. By clamping the second edge filling strip 72 between the bending structure 32 and the second intermediate layer 50, and by clamping the first edge filling strip 71 between the first glass cover plate 10 and the second intermediate layer 50, the above-mentioned stepped gap with different thicknesses can be adapted, and the edge filling effect of the light control glass 1 is improved.

[0064] Preferably, in the vertical direction perpendicular to the plane of the first glass cover plate 10, the thickness of the first edge filling strip 71 can be equal to the sum of the thicknesses of the diaphragm body 31 and the first intermediate layer 20, so that the first edge filling strip 71 can just fill the gap between the first glass cover plate 10 and the second intermediate layer 50, and the edge filling effect of the first edge filling strip 71 is improved.

[0065] In other embodiments, in the vertical direction perpendicular to the plane of the first glass cover plate 10, the thickness of the first edge filling strip 71 can be equal to the sum of the thicknesses of the diaphragm body 31 and the first intermediate layer 20, and the thickness of the first edge filling strip 71 has a first tolerance, so that the actual production needs can be adapted, and the fault tolerance of the first edge filling strip 71 is improved.

[0066] Optionally, the first tolerance has a value range of ±0.1mm, for example, the first tolerance can be -0.1mm, 0mm or 0.1mm.

[0067] Optionally, in the vertical direction perpendicular to the plane of the first glass cover plate 10, the thickness of the second edge filling strip 72 can be equal to the thickness of the diaphragm body 31, or in the vertical direction perpendicular to the plane of the first glass cover plate 10, the thickness of the second edge filling strip 72 is equal to the thickness of the diaphragm body 31, and the thickness of the second edge filling strip 72 has a second tolerance, and the second tolerance has a value range of ±0.5mm.

[0068] Specifically, in this embodiment, the thickness of the second edge-filling strip 72 is adjusted according to the thickness variation of the first intermediate layer 20, and the thickness of the second edge-filling strip 72 is set to be equal to the thickness of the diaphragm body 31, so as to adapt to most cases. More specifically, according to the thickness variation of the first intermediate layer 20, the thickness of the second edge-filling strip 72 can be adjusted within the value range of the second tolerance, so as to improve the edge-filling effect of the second edge-filling strip 72. Alternatively, the value range of the second tolerance is ±0.5mm, so as to adapt to the actual production needs and improve the fault tolerance of the second edge-filling. For example, the second tolerance can be -0.5mm, 0mm or 0.5mm.

[0069] Alternatively, in combination with Figure 2 As shown, in the plane parallel to the plane of the lap joint portion 41, the width of the second edge-filling strip 72 is consistent with the width of the lap joint portion 41, so that the second edge-filling strip 72 can just abut on the lap joint portion 41, which helps to optimize the structural arrangement and improve the structural compactness. In addition, when the light control glass 1 is placed in a high-temperature and high-pressure environment for packaging processing, it helps to improve the pressing effect of the second edge-filling strip 72 on the lap joint portion 41, and then improve the edge-filling effect of the lap joint portion 41 on the light control diaphragm 30.

[0070] In combination with Figure 4 and Figure 5 As shown, according to another aspect of the present application, the present application also provides a light control glass manufacturing method, applied to the above-mentioned light control glass 1, comprising the following steps:

[0071] Step S100, providing a first glass cover plate 10.

[0072] Step S200, laminating a first intermediate layer 20 on the first glass cover plate 10.

[0073] Step S300, laminating a light control diaphragm 30 on the side of the first intermediate layer 20 away from the first glass cover plate 10, and making the light control diaphragm 30 protrude from the first intermediate layer 20 by a first preset width D1.

[0074] Step S400, abutting an edge-filling strip 40 on the side of the light control diaphragm 30 away from the first intermediate layer 20, and making the edge-filling strip 40 protrude from the light control diaphragm 30 by a second preset width D2.

[0075] Step S500, abutting an edge-filling layer 70 on the side of the edge-filling strip 40 away from the light control diaphragm 30.

[0076] Step S600, laminating a second intermediate layer 50 on the side of the light control diaphragm 30 away from the first intermediate layer 20.

[0077] Step S700, laminating a second glass cover plate 60 on the side of the second intermediate layer 50 away from the light control diaphragm 30.

[0078] Step S800, the dimming glass 1 is placed in a high temperature and high pressure environment for packaging processing.

[0079] In combination Figure 5 As shown in step S800, the second intermediate layer 50 and the second glass cover plate 60 as a whole will be pressed downward by the pressure in the direction of the first intermediate layer 20, and then the downward pressure is transmitted to the dimming film 30 and the sealing strip 40 through the edge filling layer 70. The dimming film 30 and the sealing strip 40 are pressed and bent by the edge filling layer 70, and the dimming film 30 is bent to form a bent structure 32, and the bent structure 32 abuts against the first glass cover plate 10. The sealing strip 40 is bent to form a sealing portion 42, and the sealing portion 42 abuts against the first glass cover plate 10, thereby realizing the sealing of the liquid crystal layer end surface 30a of the dimming film 30, and protecting the liquid crystal layer of the dimming film 30 from the invasion of small molecules of the first intermediate layer 20, the second intermediate layer 50 and the edge filling layer 70.

[0080] It is worth noting that in the high temperature and high pressure environment, since the dimming film 30 protrudes from the first intermediate layer 20 by a first preset width D1, and the sealing strip 40 protrudes from the dimming film 30 by a second preset width D2, the protruding portions of the dimming film 30 and the sealing strip 40 will be bent toward the side with the gap under the action of external pressure. In the high pressure environment, the bent structure 32 formed by the dimming film 30 and the sealing portion 42 formed by the sealing strip 40 will form good adsorption connection with the first glass cover plate 10, thereby forming good sealing and sealing effect on the liquid crystal layer end surface 30a of the dimming film 30.

[0081] According to another aspect of the present application, the present application also provides a vehicle comprising the above-mentioned dimming glass 1, or comprising a dimming glass 1 prepared by the dimming glass 1 manufacturing method as described above.

[0082] The dimming glass 1 of the above-mentioned vehicle can protect the dimming film 30 from the invasion of small molecules of the first intermediate layer 20, the second intermediate layer 50 and the edge filling layer 70 during the packaging process in the high temperature and high pressure environment, and avoid the problem of failure of the dimming function of the dimming film 30.

[0083] It is worth noting that the aforementioned vehicle can include a road vehicle, a water vehicle, an air vehicle, an industrial device, an agricultural device, or an entertainment device, etc. For example, the vehicle can be a vehicle in a broad sense, which can be a vehicle (such as a commercial vehicle, a passenger vehicle, a motorcycle, a flying vehicle, a train, etc.), an industrial vehicle (such as a forklift, a trailer, a tractor, etc.), an engineering vehicle (such as an excavator, a bulldozer, a crane, etc.), an agricultural device (such as a mower, a harvester, etc.), an amusement device, a toy vehicle, etc. The type of the vehicle is not limited in the embodiments of the present application. For another example, the vehicle can be an aircraft or a ship.

[0084] Each technical feature of the above-described embodiments can be combined with any other technical feature, and for the sake of brevity, not all possible combinations are described, but it is understood that the scope of the present disclosure encompasses all such possible combinations.

[0085] The above-described embodiments are merely illustrative of several embodiments of the present application, and the description is relatively specific and detailed, but should not be understood as limiting the scope of the patent application.
