Description

Technical Field

[0001] The utility model relates to the technical field of dimming glass, and particularly relates to a dimming film, a dimming glass and a bathroom room. Background Art

[0002] A dimming glass is a laminated optoelectronic glass with a sandwich structure formed by laminating a dimming film between two layers of glass and integrally molding through high-temperature and high-pressure gluing. During use, the transparent and opaque states of the glass can be controlled by controlling the on-off of the current. In order to energize the dimming film, two electrode plates need to be led out from the dimming film for connection with an external power supply. In the prior art, in order to ensure uniform light transmission of the dimming film, the two electrode plates need to be staggeredly arranged on both side surfaces in the thickness direction of the dimming film, and are connected by an external insulating wire and a plug for connection with the external power supply.

[0003] When the dimming glass is applied to a shower room, a frame needs to be bonded to the edge of the dimming glass to cover the insulating wire. However, since the two electrodes are staggeredly arranged, at least one insulating wire needs to extend along the surface of the dimming glass. When bonding the frame, the insulating wire will lift the frame. In some technologies, in order to ensure sufficient bonding area of the frame, the width of the frame is increased, resulting in a wider frame of the dimming glass. Summary of the Utility Model

[0055] The dimming glass is a laminated optoelectronic glass with a sandwich structure formed by laminating a dimming film between two layers of glass and integrally molding it through high-temperature and high-pressure gluing. During use, the transparent and opaque states of the glass can be controlled by controlling the on-off of the current. To energize the dimming film, two electrode plates 1 need to be led out from the dimming film for connection to an external power supply. In the prior art, to ensure uniform light transmission of the dimming film, the two electrode plates 1 need to be staggeredly arranged on both side surfaces in the thickness direction of the dimming film, and are connected by an external insulating wire 2 and a plug for connection to the external power supply, as Figure 1 shown Figure 1 is a common dimming glass in the prior art.

[0056] When the dimming glass is applied to a shower room, a frame needs to be bonded to the edge of the dimming glass to cover the insulating wire. However, since the two electrodes are staggeredly arranged, at least one insulating wire needs to extend along the surface of the dimming glass, so that when the frame is bonded, the insulating wire will lift the frame. In some technologies, to ensure sufficient bonding area of the frame, the width of the frame is increased, resulting in a wider frame of the dimming glass.

[0057] Based on the above problems, the first aspect embodiment of the present invention proposes a dimming film 1000 that can be used for dimming glass to make the dimming glass have a narrower frame. Refer to Figure 2 and Figure 3 , Figure 2 is a schematic structural diagram of the first dimming film in the first aspect embodiment of the present invention, Figure 3 is Figure 2 a schematic diagram of another perspective in; the dimming film 1000 of this embodiment includes a first conductive layer 100, a second conductive layer 200, a first side surface 1100, a second side surface 1200, a liquid crystal layer 300, a first electrode 400, and a second electrode 500.

[0058] Among them, the first conductive layer 100 and the second conductive layer 200 are, for example, transparent conductive films such as ITO (indium tin oxide) conductive films, polymer conductive films, or nano-silver conductive films. Taking the ITO conductive film as an example, the ITO conductive film usually includes a PET (polyethylene terephthalate) substrate, and ITO particles are deposited on the surface of the PET substrate by magnetron sputtering to form a uniform ITO conductive film, thereby forming a light-transmitting conductive film. The first conductive layer 100 has two first surfaces 110 facing away from each other along the first direction (the thickness direction of the dimming film 1000), and a second surface 120 intersecting both of the two first surfaces 110. The second conductive layer 200 has two third surfaces 210 facing away from each other along the first direction, and a fourth surface 220 intersecting the two third surfaces 210. The first conductive layer 100 and the second conductive layer 200 are arranged at intervals along the first direction. The liquid crystal layer 300 is sandwiched between the first conductive layer 100 and the second conductive layer 200. The second surface 120 and the fourth surface 220 are located on the same side of the dimming film 1000 and together with the liquid crystal layer 300 form the first side surface 1100 of the dimming film 1000. The second side surface 1200 intersects with the first side surface 1100.

[0059] The first electrode 400 and the second electrode 500 are, for example, metal or non-metal conductive foils such as copper foil, aluminum foil, titanium foil, or composite materials. The first electrode 400 includes a first connection portion 410 and a second connection portion 420 distributed along the second direction. The first connection portion 410 and the second connection portion 420 are not limited to being the two opposite ends of the first electrode 400, and they can also be two regions inside the first electrode 400. The first connection portion 410 is electrically connected to the first surface 110. The second connection portion 420 is located on the side of the first connection portion 410 facing the second side surface 1200. In the second direction, the distance between the second connection portion 420 and the second side surface 1200 is 0 to 10 mm. For example, the second connection portion 420 is located inside the first surface 110 and the distance between it and the second side surface 1200 is 10 mm, or the second connection portion 420 protrudes from the first surface 110 along the second direction and the distance between it and the second side surface 1200 is 10 mm. Or the second connection portion 420 is flush with the second surface 120, that is, the distance between the second connection portion 420 and the second side surface 1200 is 0. That is to say, the first electrode 400 extends along the second direction, the first connection portion 410 is connected to the inside of the first surface 110, and the second connection portion 420 extends to a position close to the second side surface 1200. The second electrode 500 includes a third connection portion 510 and a fourth connection portion 520 distributed along the second direction. The third connection portion 510 is electrically connected to the side of the second surface 120 close to the first side surface 1100 and is spaced from the first connection portion 410 in the second direction. The fourth connection portion 520 is located on the side of the third connection portion 510 facing the second side surface. In the second direction, the distance between the fourth connection portion 520 and the second side surface 1200 is 0 to 10 mm. That is to say, the second electrode 500 extends along the second direction, the third connection portion 510 is located inside the second surface 120, and the fourth connection end extends to a position close to the second side surface 1200.

[0060] In this embodiment, both the first connecting portion 410 and the third connecting portion 510 are located at positions of the dimming film 1000 close to the second surface 120, and both the first electrode 400 and the second electrode 500 are located on one side of the dimming film 1000 close to the first side surface 1100. Therefore, both the second connecting portion 420 and the fourth connecting portion 520 are located at positions of the second side surface 1200 close to the edge of the first side surface 1100, that is, the first electrode 400 and the second electrode 500 are joined together at the position of the second side surface 1200 close to the first side surface 1100. Therefore, when the dimming film 1000 of this embodiment is used for a dimming glass, there is no need to arrange an external insulating wire for wire joining on the side surface of the dimming glass corresponding to the first side surface 1100 (for convenience of description, this side surface is defined as the first main side surface), thereby avoiding the external wire from lifting the frame arranged on the first main side surface, and further making the frame arranged on the first main side surface of the dimming glass narrower. Thus, not only can the light transmittance of the dimming glass be improved, but also the dimming glass can be made more beautiful.

[0061] In addition, it can be understood that since there is no need to arrange an external insulating wire on the first main side surface, the frame adhered to the first main side surface will not adhere to the external insulating wire. And since both the second connecting portion 420 and the fourth connecting portion 520 are located at positions of the second side surface 1200 of the dimming film 1000 close to the edge of the first side surface 1100, and the second connecting portion 420 and the fourth connecting portion 520 are both located on the side surface of the dimming glass corresponding to the second side surface 1200 (for convenience of description, this side surface is called the second main side surface), therefore, the frame arranged on the second main side surface will only adhere to a very small part of the external wire, or it can be made not to adhere to the external insulating wire. Therefore, when the frame needs to be removed for the maintenance of the dimming glass, the external insulating wire will not be pulled off due to the adhesion of the frame, thereby reducing the maintenance cost of the dimming glass.

[0062] As can be seen from the above embodiments, in the first direction, the first conductive layer 100 includes two opposite first surfaces 110. Therefore, the first electrode 400 can be connected to any one of the first surfaces 110. Similarly, the second electrode 500 can also be connected to any one of the third surfaces 210. Exemplarily, in the first direction, the first electrode 400 and the second electrode 500 can be disposed on the same side of the dimming film 1000, or on opposite sides of the dimming film 1000. For example, the first electrode 400 is electrically connected to the first surface 110 of the first conductive layer 100 that faces away from the second conductive layer 200. The first conductive layer 100 has a first mounting hole 130, and the liquid crystal layer 300 is provided with a second mounting hole 310 communicating therewith. The second electrode 500 is insulatingly disposed on the surface of the first conductive layer 100 that faces away from the second conductive layer 200, and extends into the first mounting hole 130 and the second mounting hole 310 to be connected to the second conductive layer 200 and insulated from the first conductive layer 100, so that the first electrode 400 and the second electrode 500 are located on the same side of the dimming film 1000.

[0063] For another example, the first electrode 400 and the second electrode 500 are respectively electrically connected to the surfaces of the first conductive layer 100 and the second conductive layer 200 that face away from each other, so that the first electrode 400 and the second electrode 500 are located on different sides of different dimming films 1000 (as Figure 3 shown). Further, taking the case where the third connecting portion 510 is located on the side of the first connecting portion 410 facing the second side surface 1200 as an example, an insulating layer 700 is further provided between the first electrode 400 and the first conductive layer 100, so that the first electrode 400 is only electrically connected to the first conductive layer 100 at the first connecting portion 410, thereby realizing the spaced arrangement of the electrical connection points of the first electrode 400 and the second electrode 500.

[0064] It should be noted that different setting methods of the first electrode 400 and the second electrode 500 respectively correspond to different effects. Taking the case where the first electrode 400 and the second electrode 500 are located on the same side as an example, they can be disposed at different positions on the first surface 110, that is, the first electrode 400 and the second electrode 500 are laid flat on the first surface 110, thereby reducing the space occupied by the first electrode 400 and the second electrode 500 in the first direction, so that the dimming film 1000 has a smaller thickness. For the case where the first electrode 400 and the second electrode 500 are located on opposite side surfaces of the dimming film 1000, in the first direction, the first electrode 400 and the second electrode 500 are disposed opposite to each other, that is, in the first direction, the projections of the first electrode 400 and the second electrode 500 coincide, thereby reducing the light-transmitting area of the dimming film 1000 occupied by the first electrode 400 and the second electrode 500.

[0065] It should be noted that the attached Figure 2The dimming film 1000 therein is a rectangular structure, which cannot be limited to the only limitation of this embodiment. According to actual usage requirements, the dimming film 1000 can be adaptively set to any polygonal structure such as a triangular structure, a quadrilateral structure, or a pentagonal structure.

[0066] Referring to Figure 4 , Figure 4 FIG. is a schematic structural diagram of the second dimming film according to the first aspect embodiment of the present invention. In some embodiments, the first conductive layer 100 has a first mounting hole 130 penetrating along the first direction, the liquid crystal layer 300 has a second mounting hole 310 penetrating along the first direction, the first mounting hole 130 communicates with the second mounting hole 310, and the third connecting portion 510 extends into the first mounting hole 130 and the second mounting hole 310 and is connected to the second surface 120 through a conductive adhesive 600. The conductive adhesive 600 is, for example, a conductive silver adhesive, a copper powder conductive adhesive 600, or a silver-copper conductive adhesive 600. Among them, the conductive silver paste has excellent electrical conductivity and good adhesion ability. The excellent electrical conductivity can more effectively transmit current, reduce resistance loss, and improve the performance of the dimming film 1000. The good adhesion ability can make the first electrode 400 more firmly bonded to the first conductive layer 100 to improve the reliability and durability of the dimming film 1000. At the same time, due to the good adhesion ability of the conductive silver paste, less conductive silver paste can be used to firmly bond the electrodes (generally referring to the first electrode 400 and the second electrode 500, unless otherwise specified, the same below) to the conductive layer (generally referring to the first conductive layer 100 and the second conductive layer 200, unless otherwise specified, the same below).

[0067] Specifically, in this embodiment, both the first electrode 400 and the second electrode 500 are in the form of foil. Connecting the first electrode 400 and the second electrode 500 with a conductive adhesive 600 can not only prevent the first electrode 400, the second electrode 500, the first conductive layer 100 and the second conductive layer 200 from being deformed by heat, but also avoid damaging the conductive films on the surfaces of the first conductive layer 100 and the second conductive layer 200 when the first conductive layer 100 and the second conductive layer 200 are non-metallic coating parts, thereby improving the quality of the dimming film 1000 and increasing the connection efficiency between the first electrode 400 and the second electrode 500. However, bonding with the conductive adhesive 600 will inevitably increase the distance between the electrode and the conductive layer. Based on this, in order to avoid the increase in the thickness of the dimming film 1000 caused by gluing. In this embodiment, the first conductive layer 100 and the liquid crystal layer 300 are respectively provided with a first mounting hole 130 and a second mounting hole 310 that communicate with each other. The third connecting portion 510 of the second electrode 500 extends into the first mounting hole 130 and the second mounting hole 310 and is connected to the second conductive layer 200 through the conductive adhesive 600. That is, the position where the second electrode 500 is adhesively bonded to the second conductive layer 200 is inside the second conductive layer 200 and the liquid crystal layer 300, and will not additionally occupy the space of the dimming film 1000 in the first direction, thereby making the dimming film 1000 thinner.

[0068] Similarly, referring to Figure 4 , in some embodiments, the second conductive layer 200 has a third mounting hole 230 that penetrates along the first direction, the liquid crystal layer 300 is provided with a fourth mounting hole 320 that communicates with the third mounting hole 230, and the first connecting portion 410 extends into the third mounting hole 230 and the fourth mounting hole 320 and is connected to the first surface 110 through the conductive adhesive 600, which will not be elaborated here.

[0069] Referring to Figure 4 , on the basis of the above embodiment, the first mounting hole 130 extends along the direction from the first connecting portion 410 to the second connecting portion 420 to the side surface of the first conductive layer 100, and the third mounting hole 230 extends along the direction from the third connecting portion 510 to the fourth connecting portion 520 to the side surface of the second conductive layer 200. Therefore, in this embodiment, the first electrode 400 is disposed in the third mounting hole 230 and is located at a position in the third mounting hole 230 extending close to the second side surface 1200, that is, the first electrode 400 is completely located in the third mounting hole 230 and will not increase the size of the dimming film 1000 in the first direction. Similarly, the second electrode 500 is disposed in the first mounting hole 130 and is located at the second side surface 1200 extending in the first mounting hole 130, and will not increase the size of the dimming film 1000 in the first direction, thereby making the dimming film 1000 of this embodiment thinner.

[0070] Referring to Figure 4, in some embodiments, in the second direction, the minimum distance between the first mounting hole 130 and the second side surface 1200 is greater than 0, that is, the first mounting hole 130 and the second side surface 1200 are spaced apart. The third mounting hole 230 is located on the side of the first mounting hole 130 facing the second side surface 1200, and the third mounting hole 230 extends along the direction from the third connecting portion 510 to the fourth connecting portion 520 to the side surface of the second conductive layer 200. The second electrode 500 extends into the first mounting hole 130 and the second mounting hole 310 and is electrically connected to the second conductive layer 200. The dimming film 1000 further includes an insulating layer 700. The insulating layer 700 is, for example, an insulating adhesive tape bonded to the first conductive layer 100, or the insulating layer 700 is provided as an insulating coating. The insulating layer 700 is located between the second electrode 500 and the first conductive layer 100, thereby preventing the second electrode 500 from being short-circuited with the first electrode 400. To improve the connection strength of the second electrode 500, the second electrode 500 and the insulating layer 700 can be bonded by glue. In the first direction, at least a part of the projection of the first electrode 400 is within the range of the second electrode 500, thereby reducing the light-transmitting area of the dimming film 1000 occupied by the first electrode 400 and the second electrode 500. Exemplarily, the first electrode 400 and the second electrode 500 are disposed opposite to each other so that the projection of the first electrode 400 is within the range of the second electrode 500, that is, the light-transmitting areas of the first electrode 400 and the second electrode 500 coincide, so as to reduce the light-shielding areas of the first electrode 400 and the second electrode 500, thereby increasing the light-transmitting area of the dimming film 1000. At the same time, the first electrode 400 and the second electrode 500 can be covered by a relatively narrow frame, so that the frame can be made narrower, making the dimming glass more beautiful.

[0071] Referring to Figure 4 , on the basis of the above embodiments, the second electrode 500 includes a first foil 501 and a second foil 502 connected to each other. The first foil 501 includes a third connecting portion 510, and the second foil 502 includes a fourth connecting portion 520. The second foil 502 is located on the surface of the insulating layer 700 facing away from the first conductive layer 100. At least a part of the second foil 502 is a first light-transmitting structure, and the position of the insulating layer 700 corresponding to the first light-transmitting structure is a second light-transmitting structure. Specifically, the first transparent structure is, for example, a light-transmitting conductive film such as an ITO film or an Sn02 film, and the second light-transmitting structure is, for example, an insulating conductive film such as a PET film, a PI (polyimide) film, or a PTFE (polytetrafluoroethylene) film. Light can pass through the first light-transmitting structure and the second light-transmitting structure. Therefore, when the dimming film 1000 of this embodiment is used for a dimming glass, the light-transmitting area of the dimming glass can be increased, thereby enhancing the indoor brightness.

[0072] The first foil 501 includes a third connecting portion 510 and is connected to the second foil 502. Therefore, the first foil 501 needs to extend into the first mounting hole 130 and the second mounting hole 310, and is bent to be connected to the second conductive layer 200. Based on this, the first foil 501 is a flexible conductive foil such as a copper foil, an aluminum foil, or a nano-composite flexible conductive foil, etc., to improve the bendability of the first foil 501, prevent the first foil 501 from being damaged by bending and affecting the electrical conductivity, thereby improving the reliability of the dimming film 1000.

[0073] Based on the above embodiments, the fourth connecting portion 520 is a metal foil. Specifically, as can be seen from the above embodiments, the first electrode 400 and the second electrode 500 need to be connected to the plug. Based on this, in this embodiment, the fourth connecting portion 520 is a metal thin sheet structure. Therefore, when the dimming film 1000 of this embodiment is used for a dimming glass, a wire can be welded to the end of the second electrode 500 for connection to the plug, improving the connection strength between the wire and the second electrode 500, thereby improving the quality of the dimming film 1000. Specifically, when connecting to the plug, it is inevitable to exert a certain pulling force on the external wire. Therefore, a high connection strength is required between the external wire and the second electrode 500 to avoid the external wire falling off. In this embodiment, the external wire is welded to the fourth connecting portion 520, improving the connection strength between the external wire and the second electrode 500.

[0074] In some embodiments, the width of the first electrode 400 is 4 mm to 8 mm. Specifically, the first electrode 400 is connected to the first conductive layer 100 for external power connection. Therefore, if the width of the first electrode 400 is too small, the current-carrying capacity of the first electrode 400 will be low, resulting in easy heating during operation, and if the width is too small, the connection area between the first electrode 400 and the first conductive layer 100 will be too small, prone to poor contact and other situations. However, if the first electrode 400 is too wide, the light-transmitting area of the dimming film 1000 will be reduced. Based on this, in this embodiment, the width of the first electrode 400 is set within a suitable range, such that the width of the first electrode 400 not only meets the current-carrying requirements but also does not occupy too large a light-transmitting area, while improving the stability of the electrical connection with the first conductive layer 100. Similarly, in some embodiments, the width of the second electrode 500 is 4 mm to 8 mm, which will not be elaborated here.

[0075] In some embodiments, the thickness of the first electrode 400 is from 0.08 mm to 0.1 mm. Specifically, the thinner the first electrode 400 is, the smaller the overall thickness of the dimming film 1000 can be. However, being too thin will not only reduce the current-carrying capacity of the first electrode 400, but also increase the processing requirements and thus the cost. Based on this, in this embodiment, the thickness of the first electrode 400 is from 0.08 mm to 0.1 mm, which makes it within a suitable range. Similarly, in some embodiments, the thickness of the second electrode 500 is from 0.08 mm to 0.1 mm, which will not be elaborated here.

[0076] In some embodiments, in the second direction, the length of the first connecting portion 410 is L 1 , and the length of the first side surface 1100 is L 2 , L 1 / L 2 is from 1 / 3 to 2 / 5. Specifically, the longer the first connecting portion 410 is, the more reliable the electrical connection between the first electrode 400 and the first conductive layer 100 is. However, if the first connecting portion 410 is too long, the distance between the first connecting portion 410 and the second connecting portion 420 will be too small, resulting in uneven electric fields in the liquid crystal layer 300. Based on this, on the premise of ensuring the uniformity of the electric field in the liquid crystal layer 300 and the reliability of the electrical connection between the first electrode 400 and the first conductive layer 100, in this embodiment, L 1 / L 2 is set within the range of 1 / 3 to 2 / 5. Similarly, in some embodiments, in the second direction, the length of the third connecting portion 510 is L3, and L 3 / L 2 is from 1 / 3 to 2 / 5, which will not be elaborated here.

[0077] Refer to Figure 5 , Figure 5The figure is a schematic structural view of the dimming glass according to the second aspect of the present utility model. The dimming glass according to the second aspect of the present utility model includes a first glass 2000, a second glass 3000, and the dimming film 1000 according to the first aspect of the present utility model. The first glass 2000 and the second glass 3000 are arranged at intervals along a first direction, and the dimming film 1000 is located between the first glass 2000 and the second glass 3000. Specifically, in the dimming film 1000, both the first connecting portion 410 and the third connecting portion 510 are located at positions close to the second surface 120 of the dimming film 1000, and both the first electrode 400 and the second electrode 500 are located on one side of the dimming film 1000 close to the first side surface 1100. Therefore, both the second connecting portion 420 and the fourth connecting portion 520 are located at positions close to the edge of the first side surface 1100 on the second side surface 1200, that is, the first electrode 400 and the second electrode 500 are combined into a line at a position on the second side surface 1200 close to the first side surface 1100. Therefore, there is no need to provide an external insulating wire for combining lines on the first main side surface of the dimming glass, thereby avoiding the external insulating wire from lifting the frame provided on the first main side surface, and further making the frame provided on the first main side surface of the dimming glass narrower. Thus, not only can the light transmittance of the dimming glass be improved, but also the dimming glass can be made more beautiful.

[0078] It should be noted that since this embodiment adopts all the technical features of the dimming film 1000 according to the first aspect of the present utility model, this embodiment has all the beneficial effects brought by the first aspect of the present utility model.

[0079] Refer to Figure 5 and Figure 6, in some embodiments, the dimming film 1000 has a first receiving groove 1300 that extends along a second direction to the edge of the dimming film 1000. The second side surface 1200 includes an inner wall surface of the first receiving groove 1300 facing the second direction. A second receiving groove 2100 is provided at the position corresponding to the first receiving groove 1300 on the first glass 2000, and a third receiving groove 3100 is provided at the position corresponding to the first receiving groove 1300 on the second glass 3000. The first receiving groove 1300, the second receiving groove 2100, and the third receiving groove 3100 define a clearance groove 4000. The dimming glass further includes a wiring assembly 5000, and the wiring assembly 5000 includes a first insulated wire 5100 and a second insulated wire 5200. The first insulated wire 5100 and the second insulated wire 5200 are respectively electrically connected to the second connecting portion 420 and the fourth connecting portion 520 and both extend into the clearance groove 4000. Thus, when connecting a plug, the plug can be received in the clearance groove 4000, thereby avoiding the plug occupying the space outside the dimming glass, which is beneficial to more compactly installing the dimming glass in a frame (such as a door frame, a wall), or when it is necessary to connect to an external wire, the connection portion of the external wire with the first insulated wire 5100 and the second insulated wire 5200 can be received in the clearance groove 4000.

[0080] The bathroom room according to the third aspect embodiment of the present invention includes the dimming glass according to the second aspect embodiment. The dimming glass has a narrower frame, thereby increasing the proportion of the glass, enabling more light to freely penetrate, and making the bathroom room brighter and more open.
