[0002] With the advancement of the four modernizations of automobiles, the market demand for automotive dimming glass continues to increase. Dimming glass is a type of glass that uses electricity to adjust the light line of sight. Its structure is to encapsulate the dimming film between two layers of glass with a film, and form laminated glass after high-temperature and high-pressure encapsulation processing. However, in the related technology, during the encapsulation process, the small molecules in the film under high temperature and high pressure will invade the liquid crystal layer of the dimming film, causing the dimming function of the edge 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.

[0044] Considering that during the packaging process of 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 dimming function of the edge 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 carrier.

[0045] For details, please refer to the attached Figure 1 An embodiment of the present application provides a dimming glass 1, which may include a first glass cover plate 10, a first intermediate layer 20, a dimming film 30, an edge seal 40, a second intermediate layer 50, a second glass cover plate 60 and an edge filler layer 70. The first intermediate layer 20 is stacked on the first glass cover plate 10. Figure 2 As shown, the dimming film 30 includes a connected film body 31 and a bending structure 32, 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 relative to the film body 31 toward the side close to the first glass cover plate 10 and abuts against the first glass cover plate 10. The edge sealing strip 40 includes a connected overlapping portion 41 and an edge sealing portion 42, the overlapping 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 toward 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 filling layer 70 is sandwiched 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 dimming film 30 comprises 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. Figure 2 As shown, when the dimming film 30 is not edge-sealed, the invasion path of small molecules of the first intermediate layer 20 , the second intermediate layer 50 and the edge-filling layer 70 is to invade the liquid crystal layer from the liquid crystal layer end surface 30 a of the dimming film 30 .

[0047] The dimming glass 1 of the present application is firstly bent relative to the membrane body 31 toward the side close to the first glass cover plate 10 by the bending structure 32 and abutted against the first glass cover plate 10, so that the small molecules of the first intermediate layer 20 cannot penetrate into the liquid crystal layer end face 30a of the dimming membrane 30; secondly, the overlapping 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 toward 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 filling layer 70 cannot penetrate into the liquid crystal layer end face 30a of the dimming membrane 30, and then the dimming membrane 30 can be fully protected 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 a high temperature and high pressure environment, thereby avoiding the problem of failure of the dimming function of the dimming membrane 30.

[0048] Optionally, the first intermediate layer 20 and the second intermediate layer 50 may be made of, but not limited to, materials such as PVB (PolyvinylButyral), EVA (Ethylene Vinyl Acetate Copolymer) or TPU (Thermoplastic Urethane).

[0049] Optionally, the edge banding strip 40 may be made of, but is not limited to, PET (Polyethylene terephthalate), PP (Polypropylene) or PE (Polyethylene).

[0050] Optionally, combined Figure 2 As shown, 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 filling layer 70 can be arranged flush with each other, which can improve the appearance of the dimming glass 1 and ensure the mutual pressure effect of the first glass cover plate 10, the second glass cover plate 60, the second intermediate layer 50 and the edge filling layer 70 at the edge position.

[0051] It should be noted that a filling layer 70 can be provided 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 with the filling layer 70, thereby improving the mutual pressure effect between the first glass cover plate 10, the first intermediate layer 20, the dimming film 30, the second intermediate layer 50 and the second glass cover plate 60.

[0052] Preferably, combined Figure 3 As shown, the dimming film 30 is parallel to the first intermediate layer 20 in a flattened state, and on the plane where the dimming film 30 and the first intermediate layer 20 contact each other, the dimming film 30 protrudes from the first intermediate layer 20 by a first preset width D1. By controlling the protruding width of the dimming film 30 from the first intermediate layer 20, it can be ensured that after the protruding portion of the dimming film 30 is bent to form a bending structure 32, the bending structure 32 has a sufficient area to contact the first glass cover plate 10. At the same time, it can also be ensured that the bending structure 32 has a sufficient area for the overlapping portion 41 of the edge sealing strip 40 to overlap and seal the edge, thereby improving the edge sealing effect of the bending structure 32.

[0053] More preferably, the value range of the first preset width D1 may be greater than or equal to 3 mm. For example, the first preset width D1 may be 3 mm, 4 mm, or 5 mm.

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

[0055] More preferably, the value range of the second preset width D2 may be greater than or equal to 3 mm, for example, the second preset width D2 is 3 mm, 4 mm or 5 mm.

[0056] Preferably, continue to combine Figure 3 As shown, the cross-sectional thickness d of the edge banding strip 40 may be less than or equal to 0.2 mm. Thus, by controlling the thickness of the edge banding strip 40 , the problem of glass cracking caused by the edge banding strip 40 being too thick can be prevented.

[0057] Specifically, when the edge seal 42 and the first glass cover plate 10 are in contact with each other, if the edge seal 42 is too thick, a large concentrated stress will be generated, which will then cause the glass cracking problem. Therefore, in this embodiment, by controlling the thickness of the edge seal 40, the production qualification rate and product quality of the dimming glass 1 are improved. In addition, controlling the thickness of the edge seal 40 also helps to prevent the problem of unstable adsorption between the overlap 41 and the dimming film 30, and between the edge seal 42 and the first glass cover plate 10 caused by the edge seal 40 being too thick, thereby improving the edge sealing effect of the edge seal 40 on the dimming film 30.

[0058] Optionally, revisit Figure 2 The bending structure 32 may include a bending portion 321 and a first abutting portion 322. The bending portion 321 is connected to the diaphragm body 31 and deviates from the side of the diaphragm body 31 toward the first glass cover plate 10, and is extended at a preset angle. The first abutting portion 322 is connected to the extended end of the bending portion 321 and abuts against the first glass cover plate 10.

[0059] Specifically, the bending portion 321 deviates toward the side close to the first glass cover plate 10 and is extended at a preset angle, so that the bending portion 321 can avoid the first intermediate layer 20 and smoothly extend to the position of the first glass cover plate 10 to connect with the first abutting portion 322, and the structural arrangement is simple and reliable. According to the above embodiment of the present application, the overlapping portion 41 can abut against the side of the first abutting portion 322 away from the first glass cover plate 10.

[0060] Optionally, continue to Figure 2 The edge sealing portion 42 may include an extension portion 421 and a second abutting portion 422. One end of the extension portion 421 is connected to the overlapping portion 41, and the other end of the extension portion 421 extends toward a side close to the first glass cover plate 10 and is connected to the second abutting portion 422. The second abutting portion 422 abuts against the first glass cover plate 10, thereby achieving edge sealing of the dimming film 30 by the edge sealing portion 42.

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

[0062] Preferably, combined Figure 2As shown, the edge-filling layer 70 may include a first edge-filling strip 71 and a second edge-filling strip 72. The first edge-filling strip 71 is sandwiched between the first glass cover plate 10 and the second intermediate layer 50, and the second edge-filling strip 72 is sandwiched between the bending structure 32 and the second intermediate layer 50. In this way, different first edge-filling strips 71 and second edge-filling strips 72 are used to fill the edges of the dimming glass 1, which helps to adapt to the gap shape at the edge position of the first glass cover plate 10 and the second intermediate layer 50, thereby improving the 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 sandwiching the second filling strip 72 between the bending structure 32 and the second intermediate layer 50, and by sandwiching the first filling strip 71 between the first glass cover plate 10 and the second intermediate layer 50, it is possible to adapt to the stepped gaps with different thicknesses, thereby improving the filling effect of the dimming glass 1.

[0064] Preferably, in the vertical direction perpendicular to the plane of the first glass cover plate 10, the thickness of the first edge filler 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 filler strip 71 can just fill the gap between the first glass cover plate 10 and the second intermediate layer 50, thereby improving the edge filler effect of the first edge filler strip 71.

[0065] In some other embodiments, in the vertical direction perpendicular to the plane of the first glass cover plate 10, the thickness of the first edge filler 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 filler strip 71 has a first tolerance, which can adapt to actual production needs and improve the fault tolerance of the first edge filler strip 71.

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

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

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

[0069] Optionally, combined Figure 2 As shown, on a plane parallel to the plane of the overlapped portion 41, the width of the second edge filler strip 72 is consistent with the width of the overlapped portion 41, so that the second edge filler strip 72 can just abut against the overlapped portion 41, which helps to optimize the structural arrangement and improve the compactness of the structure. In addition, when the dimming 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 filler strip 72 on the overlapped portion 41, and then improve the edge sealing effect of the overlapped portion 41 on the dimming film 30.

[0070] Combination Figure 4 and Figure 5 As shown, according to another aspect of the present application, the present application also provides a method for manufacturing a dimming glass, which is applied to the above-mentioned dimming glass 1 and includes the following steps:

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

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

[0073] Step S300 , stacking the dimming film 30 on the side of the first intermediate layer 20 away from the first glass cover plate 10 , and protruding the dimming film 30 from the first intermediate layer 20 by a first preset width D1 .

[0074] Step S400 , the edge sealing strip 40 is abutted against the side of the dimming film 30 away from the first intermediate layer 20 , and the edge sealing strip 40 is protruded by a second preset width D2 relative to the dimming film 30 .

[0075] Step S500 , placing the edge-filling layer 70 against the side of the edge-sealing strip 40 facing away from the dimming film 30 .

[0076] Step S600 , stacking the second intermediate layer 50 on the side of the dimming film 30 away from the first intermediate layer 20 .

[0077] Step S700 , stacking the second glass cover plate 60 on the side of the second intermediate layer 50 facing away from the dimming film 30 .

[0078] Step S800: placing the switchable glass 1 in a high temperature and high pressure environment for packaging processing.

[0079] Combination Figure 5 As shown, in step S800, the second intermediate layer 50 and the second glass cover plate 60 are pressed downward toward the first intermediate layer 2030 as a whole under pressure, and then the downward pressure is transmitted to the dimming film 30 and the edge sealing strip 40 through the edge filling layer 70. The dimming film 30 and the edge sealing strip 40 are bent downward 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, and the edge sealing strip 40 is bent to form an edge sealing portion 42, and the edge sealing portion 42 abuts against the first glass cover plate 10, so as to achieve sealing of the end face 30a of the liquid crystal layer of the dimming film 30, and protect 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 a high temperature and high pressure environment, since the dimming film 30 protrudes by the first preset width D1 compared to the first intermediate layer 20, and the edge sealing strip 40 protrudes by the second preset width D2 compared to the dimming film 30, the protruding parts of the dimming film 30 and the edge sealing strip 40 will bend toward the side with the gap under the action of external pressure, and under the high pressure environment, the bending structure 32 formed by the bending of the dimming film 30 and the edge sealing portion 42 formed by the bending of the edge sealing strip 40 will form a good adsorption connection with the first glass cover plate 10, thereby forming a good sealing and edge sealing effect on the liquid crystal layer end face 30a of the dimming film 30.

[0081] According to another aspect of the present application, the present application further provides a vehicle, which includes the above-mentioned dimming glass 1, or includes the dimming glass 1 prepared by the above-mentioned method for preparing the dimming glass 1.

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

[0083] It is worth noting that the aforementioned vehicles may include road vehicles, water vehicles, air vehicles, industrial equipment, agricultural equipment, or entertainment equipment, etc. For example, the vehicle may be a vehicle, which is a vehicle in a broad sense, and may be a vehicle (such as a commercial vehicle, a passenger car, a motorcycle, a flying car, 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.), agricultural equipment (such as a lawn mower, a harvester, etc.), amusement equipment, a toy vehicle, etc. The embodiment of the present application does not specifically limit the type of vehicle. For another example, the vehicle may be a vehicle such as an airplane or a ship.

[0084] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
