Description

[0001] The present invention belongs to the technical field of dimming glass, and particularly relates to a novel liquid crystal dimming glass with a lead structure. Background Art

[0002] Currently, automotive dimming glass is generally used on the automotive sunroof and not on the side windows of automobiles. The general manufacturing method of currently adjustable automotive glass is to relatively arrange two layers of ordinary glass and sandwich a liquid crystal material layer between the two layers of ordinary glass. Its leads are pre-installed inside the two layers of ordinary glass, enabling the side window glass to have functions such as dimming, sunshading, heat insulation, display, and privacy shielding.

Detailed implementation mode

[0032] Next, the technical solutions of the invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the invention without creative work shall fall within the scope of protection of the invention.

[0033] In the description of the invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0034] Such as Figure 1 - Figure 6As shown in the figure, a new type of liquid crystal dimming glass with a lead structure includes: a first substrate layer 100, a liquid crystal dimming layer 200, and a second substrate layer 300. The liquid crystal dimming layer 200 is disposed between the first substrate layer 100 and the second substrate layer 300. A lead layer 400 is further disposed between the first substrate layer 100 and the second substrate layer 300. The lead layer 400 is located on one side of the liquid crystal dimming layer 200 and is electrically connected thereto. Through holes 600 for installing a lead structure 500 are formed in the first substrate layer 100, the second substrate layer 300, and the lead layer 400. The lead structure 500 is electrically connected to the lead layer 400. The liquid crystal dimming layer 200 includes: a first conductive layer 210, a microstructured liquid crystal layer 220, and a second conductive layer 230. The microstructured liquid crystal layer 220 is disposed between the first conductive layer 210 and the second conductive layer 230. The first conductive layer 210 is attached to the first substrate layer 100, and the second conductive layer 230 is attached to the second substrate layer 300. The lead structure 500 includes: a double-layer connection mechanism 510, a driving mechanism 520, a lead terminal 530, and a fixed base 540. The double-layer connection mechanism 510 is installed inside the through hole 600. The double-layer connection mechanism 510 is cooperatively connected to the lead layer 400. A driving mechanism 520 for driving the double-layer connection mechanism 510 to rotate is installed on the double-layer connection mechanism 510. The lead terminal 530 and the fixed base 540 are cooperatively installed in the through hole 600. The lead terminal 530 is electrically connected to the double-layer connection mechanism 510.

[0035] Among them, the first substrate layer 100 and the second substrate layer 300 are PET films. Of course, according to actual requirements, other materials suitable for use as substrates can be selected as the substrate layers, such as: transparent PC boards, transparent glass. It also includes a controller (not marked in the figure). The controller is provided with a control circuit. The liquid crystal dimming layer 200 is electrically connected to the control circuit. The controller is used to control the electric field situation between the liquid crystal dimming layer 200 and display the charging status and the temperature inside the vehicle.

[0036] In the present invention, a lead layer 400 is further disposed between the first substrate layer 100 and the second substrate layer 300. At the same time, in cooperation with the lead structure 500, a detachable structure of the lead structure 500 is realized, effectively preventing the problem that the lead is broken from the root and the automotive side window dimming glass cannot be used. At the same time, in the present invention, any opening can be made in the lead layer 400 and the lead structure can be used multiple times in cooperation, achieving the function of extending the service life.

[0037] Among them, the liquid crystal mixture in the microstructured liquid crystal layer 220 preferably uses GH liquid crystal to achieve a better experience of stepless dimming of light and darkness. By using a GH guest-host dye liquid crystal, a guest-host relationship is formed by dissolving a dichroic dye in the liquid crystal. The liquid crystal is the host, and the dichroic dye is the guest. Under the action of an external electric field, the guest follows the host, and the dye molecules rotate with the liquid crystal molecules. The dichroic dye has the property of anisotropy of light absorbance. According to the orientation relationship between the absorption axis of the dye molecule and the molecular axis, dichroic dyes can be divided into positive (P-type) dichroic dyes and negative (N-type) dichroic dyes. When the E vector of the light is perpendicular to the optical axis of the dye, the light basically passes through; however, when the E vector of the light is parallel to the optical axis of the dye, the light is basically absorbed. This type of dye is a positive dichroic dye, and the negative dichroic dye is exactly the opposite. According to the characteristics of positive and negative dyes, light absorption or transmission occurs, thereby changing the transmittance of the microstructured liquid crystal layer 220. Therefore, this type of liquid crystal becomes a guest-host (GH) type liquid crystal. Since the guest-host liquid crystal can be used without attaching a polarizer and utilizes the selective transmission of light by the dichroic dye, it can meet the performance requirements of the liquid crystal dimming layer 200, can achieve the adjustment of light and darkness of the liquid crystal film, and maintain a high transmittance effect. It can also adjust the color of the liquid crystal film in the dark state through the color adjustment of the dichroic dye. Of course, if the automotive glass made of the liquid crystal film of the present invention is desired to have the effect of privacy glass, then one of PDLC liquid crystal, PNLC liquid crystal, and PSCT liquid crystal is selected, and PNLC liquid crystal is preferred.

[0038] The liquid crystal dimming glass of the present application has the functions of dimming, sunshading, heat insulation, display, and privacy shielding.

[0039] The microstructured liquid crystal layer 220 includes a bottom plate 221, a partition plate 222, and a polygonal storage space 223. The partition plate 222 is vertically arranged on the bottom plate 221. The bottom plate 221 is pasted on the second conductive layer 230. The partition plate 222 divides the space between the bottom plate 221 and the first conductive layer 210 into several polygonal storage spaces 223. The liquid crystal mixture is poured into the polygonal storage spaces 223, ensuring that the thickness of the liquid crystal film will not become locally larger or smaller due to bending during the deformation process.

[0040] Preferably, the polygonal storage space 223 is a regular hexagon space (it can be set to other shapes). Setting the polygonal storage space 223 to a regular hexagon structure can make the microstructured liquid crystal layer 220 stronger and more excellent in the ability to withstand high temperature and high pressure.

[0041] According to Figure 3, the lead layer 400 includes: a third conductive layer 410, a fourth conductive layer 420, and an insulating layer 430. The insulating layer 430 is disposed between the third conductive layer 410 and the fourth conductive layer 420. The third conductive layer 410 is attached to the first substrate layer 100, and the fourth conductive layer 420 is attached to the second substrate layer 300. The third conductive layer 410 is electrically connected to the first conductive layer 210, and the fourth conductive layer 420 is electrically connected to the second conductive layer 230. The insulating layer 430 is located on one side of the microstructured liquid crystal layer 220. The thicknesses of the third conductive layer 410 and the fourth conductive layer 420 are greater than those of the first conductive layer 210 and the second conductive layer 230. The double-layer connection mechanism 510 is cooperatively connected to both the third conductive layer 410 and the fourth conductive layer 420.

[0042] Among them, the third conductive layer 410 and the fourth conductive layer 420 can be made of a soft metal with good conductivity, such as silver, which is convenient for connecting with the double-layer connection mechanism 510.

[0043] In this application, both the third conductive layer 410 and the fourth conductive layer 420 are sealed into the first substrate layer 100 and the second substrate layer 300. When connecting the double-layer connection mechanism 510, only need to open holes in the lead layer 400, which is convenient and fast.

[0044] According to Figure 7 - Figure 12 , the double-layer connection mechanism 510 includes: a fixing ring 511, a driving ring 512, a conductive sheet 513, and a guiding column 514. The fixing ring 511 is fixedly installed in the through hole 600. A plurality of guiding columns 514 are circumferentially arranged on both the upper and lower end faces of the fixing ring 511. Arc-shaped grooves 515 are provided on both the upper and lower end faces of the conductive sheet 513. The arc-shaped grooves 515 are used in cooperation with the guiding columns 514. A plurality of arc-shaped holes 516 are circumferentially opened on the fixing ring 511. A hinge hole 517 is opened on the conductive sheet 513. Driving holes 518 are circumferentially opened on the driving ring 512. A driving column 519 is placed in the arc-shaped hole 516, the hinge hole 517, and the driving hole 518. The upper end of the driving column 519 is fixedly connected to the driving mechanism 520, and the lower end of the driving column 519 is slidably connected to the fixed base 540.

[0045] Among them, the outer wall of the fixing ring 511 is adhered to the insulating layer 430 with glue for fixation. The surface of the conductive sheet 513 in contact with the third conductive layer 410 and the fourth conductive layer 420 is provided with a cutting edge to facilitate the embedding of the conductive sheet 513 therein.

[0046] In this application, by rotating the driving ring 512, the conductive sheet 513 is driven to rotate along the hinge hole 517, and then the conductive sheet 513 is embedded into the third conductive layer 410 or the fourth conductive layer 420 to achieve electrical connection. The embedded connection method is more stable and improves the connection strength.

[0047] According to Figure 7 、Figure 8 , Figure 11 and Figure 12 , the conductive sheet 513 includes: a first conductive part 5131, an insulating part 5132, and a second conductive part 5133. One side of the insulating part 5132 is provided with the first conductive part 5131, and the first conductive part 5131 is cooperatively connected with the lead layer 400. The other side of the insulating part 5132 is embedded with the second conductive part 5133, and the second conductive part 5133 is cooperatively connected with the lead terminal 530. The arc-shaped groove 515 and the hinge hole 517 are both opened on the insulating part 5132.

[0048] Among them, the first conductive part 5131 and the second conductive part 5133 are electrically connected by a wire, and the wire is located inside the insulating part 5132. The first conductive part 5131 is provided with a cutting edge to facilitate the embedding of the conductive sheet 513 into the third conductive layer 410 and the fourth conductive layer 420.

[0049] The present invention is provided with the insulating part 5132 to ensure that the exposed part does not conduct electricity when the conductive sheet 513 is in the overall closed state. At the same time, the other side of the insulating part 5132 is embedded with the second conductive part 5133 to also prevent exposure, thereby playing an insulating and sealing role in the unused state.

[0050] According to Figure 11 and Figure 12 , a plurality of arc-shaped limiting grooves 541 are circumferentially and arrayedly opened on one end face of the fixed base 540. The cross-section of the arc-shaped limiting groove 541 is T-shaped. The lower end of the driving column 519 is provided with a T-shaped slider 542. A through hole 543 for passing the T-shaped slider 542 is opened at one end of the arc-shaped limiting groove 541, and the T-shaped slider 542 is slidably matched with the arc-shaped limiting groove 541.

[0051] The present invention realizes the connection between the driving column 519 and the fixed base 540 through the sliding fit of the T-shaped slider 542 and the arc-shaped limiting groove 541, and thus realizes the installation. The driving mechanism 520 is specifically a ring structure, and the side wall of the driving mechanism 520 is provided with anti-slip patterns.

[0052] According to Figure 3 and Figure 11 , the lead terminal 530 includes: a screwing disc 531, a wire harness 532, an insulating column 533, and an elastic conductive mechanism 534. The lower end face of the screwing disc 531 is coaxially provided with the insulating column 533. A plurality of elastic conductive mechanisms 534 are circumferentially and arrayedly arranged on the side wall of the insulating column 533. The elastic conductive mechanisms 534 are in two groups up and down. The elastic conductive mechanisms 534 are cooperatively connected with the second conductive part 5133. The wire harness 532 is arranged on the screwing disc 531, and the wire harness 532 is electrically connected with the elastic conductive mechanism 534. The lower end of the insulating column 533 is threadedly connected with the fixed base 540.

[0053] The lower end of the insulating column 533 of the present invention is threadedly connected to the fixed base 540 to achieve detachable connection. The elastic conductive mechanism 534 is electrically connected to the second conductive part 5133. The elastic conductive mechanism 534 is divided into upper and lower layers for connecting the two poles.

[0054] According to Figure 5 , the elastic conductive mechanism 534 includes: a conductive block 5341, a limiting ring 5342 and a thrust spring 5343. A plurality of mounting grooves 5344 are circumferentially arranged on the side wall of the insulating column 533. The mounting grooves 5344 are divided into upper and lower groups. A limiting ring groove 5345 is provided inside the mounting groove 5344. The conductive block 5341 is placed in the mounting groove 5344. A limiting ring 5342 is sleeved on the conductive block 5341. The limiting ring 5342 is placed in the limiting ring groove 5345. A thrust spring 5343 is arranged in the mounting groove 5344. The thrust spring 5343 is located between the conductive block 5341 and the bottom of the mounting groove 5344. The conductive block 5341 is cooperatively connected with the second conductive part 5133. The second conductive part 5133 is electrically connected to the wire harness 532. A guiding angle is provided on the conductive block 5341.

[0055] In the present application, the conductive block 5341 can be inserted into the mounting groove 5344 under pressure, which is convenient for insertion. At the same time, a thrust spring 5343 is provided to ensure good contact with the second conductive part 5133.

[0056] Working principle:

[0057] First, a through hole 600 is opened in the area involved in the lead layer 400. The position where the through hole 600 is opened depends on the vehicle model. The outer wall of the fixing ring 511 of the double-layer connection mechanism 510 is coated with an adhesive. The double-layer connection mechanism 510 is placed in the through hole 600. The outer wall of the fixing ring 511 is closely attached to the insulating layer 430. The lower end of the driving column 519 is slidably installed in the arc-shaped limiting groove 541 of the fixed base 540. The driving mechanism 520 is screwed. The driving mechanism 520 drives the lower end of the driving column 519 to slide in the arc-shaped limiting groove 541. At the same time, the driving column 519 drives the driving ring 512 and the conductive sheet 513 to rotate around the axis of the fixing ring 511. The guiding column 514 cooperates with the arc-shaped groove 515 on the conductive sheet 513. Since the position of the guiding column 514 relative to the first base layer 100 remains unchanged, the conductive sheet 513 rotates around the driving column 519. Then, the first conductive part 5131 of the conductive sheet 513 contacts and is embedded in the first conductive layer 210 or the second conductive layer 230 to achieve electrical connection.

[0058] Then, the insulating column 533 of the lead terminal 530 is inserted into the double-layer connection mechanism 510. During the insertion process, the conductive block 5341 of the elastic conductive mechanism 534 is compressed into the mounting groove 5344. When the insulating column 533 is completely inserted, the driving screw plate 531 is rotated, so that the lower end of the insulating column 533 is threadedly connected to the fixed base 540.

Additionally, under the teaching of the invention, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the invention.
