The light-regulating hollow glass is made up by adhering the functional material of polymer dispersed liquid crystal, etc. on the base material of glass or film, etc. and embedding it in the hollow glass, and controlling the colour depth of glass and regulating sunlight-incoming intensity by means of controlling voltage or current change so as to make the light ray passed through the glass soft, comfortable and pleasant, and do not lose light-transmitting action. The glass can be in normal phase dimming, namely fuzzy when the power is off, and clear when the power is on, or in reverse phase dimming, clear when the power is off, and fuzzy when the power is on. For example, chinese patent CN202727454U discloses a smart electrically controlled dimming hollow glass, which comprises a hollow glass, a first adhesive layer, a first conductive layer, a polymer dispersed liquid crystal layer, a second conductive layer, a second adhesive layer and a hard film layer.
In actual use, after a functional material such as liquid crystal is attached to a base material, if the base material is deformed by pressure, the color of the liquid crystal changes, and the pressed part has uneven color. Above-mentioned automatically controlled hollow glass that adjusts luminance of intelligence is applied to static, when atress is less in the building structure, obvious visual defect can not appear, but when this hollow glass that adjusts luminance is applied to vehicles such as big bus, high-speed railway, because vehicle can receive the influence of wind pressure at the in-process glass of driving, and can change at the in-process speed of driving, the liquid crystal is very easy to take place the transmittance change because of pressure, influence the vision, above-mentioned change can form irreversible state when being in this state for a long time, influence normal use. In addition, the light transmittance of the liquid crystal may fluctuate due to vertical vibration generated during the driving of the vehicle.
Disclosure of Invention
In order to solve the problems, the invention provides the four-glass two-cavity hollow glass which can prevent a functional layer formed by polymer dispersed liquid crystal from being influenced by external pressure and vibration, so that the functional layer can normally adjust the transmittance in the use process of the glass.
In order to achieve the purpose, the invention adopts the following technical scheme:
a four-glass two-cavity hollow glass comprises a first glass, a second glass, a third glass and a fourth glass which are sequentially arranged, wherein an adhesive body is arranged between the second glass and the third glass, the second glass, the third glass and the adhesive body jointly form a dimming assembly, the adhesive body comprises a first adhesive layer, a dimming functional layer and a second adhesive layer which are sequentially arranged, the light transmittance of the dimming functional layer can be changed after the dimming functional layer is electrified, the second glass and the adhesive body are bonded through the first adhesive layer, and the third glass and the adhesive body are bonded through the second adhesive layer; the outer end part of the dimming component is provided with a frame piece; the side of the frame piece facing the dimming assembly is provided with a clamping groove, and the clamping groove comprises a limiting surface attached to two side surfaces of the dimming assembly and a butting surface attached to the end surface of the dimming assembly; an annular spacing frame is arranged between the first glass and the fourth glass, and the first glass and the fourth glass are respectively bonded with two sides of the spacing frame; the dimming assembly is arranged at the annular inner end of the spacing frame, and two sides of the frame piece are respectively bonded with the first glass and the third glass; a first cavity is formed between the first glass and the dimming assembly, and a second cavity is formed between the fourth glass and the dimming assembly.
When the common hollow glass is produced, a spacing frame is usually arranged between two glass sheets and is in a rectangular annular structure, and after the spacing frame and the two glass sheets are attached by using a sealant, a hollow sealing structure clamped by the two glass sheets is formed in the middle of the spacing frame. The invention can be seen as that the light adjusting component is additionally arranged in the hollow sealing structure, the light adjusting component divides the hollow sealing structure into a first cavity and a second cavity, namely two-cavity hollow glass is formed, and the light adjusting component is formed by the second glass, the third glass and the rubber insert, so that the invention is the four-glass two-cavity hollow glass as a whole.
In the scheme of the invention, the dimming component is positioned in a large cavity formed between the first glass and the fourth glass, a smaller first cavity is formed between the second glass forming the dimming component and the first glass on the outer side, a smaller second cavity is formed between the third glass forming the dimming glass and the fourth glass on the outer side, when the glass is subjected to lateral external force, the external force can directly act on the first glass and the fourth glass, then the external force acts on the spacing frame and the side frame member at the end part of the dimming component through the first glass and the fourth glass, the spacing frame and the side frame member counteract the external force through self structures, and the sandwiched colloid is basically not influenced in the process, so that the transmittance change cannot be generated. Because the side of frame piece orientation subassembly of adjusting luminance is equipped with the joint groove on, the joint groove include with the spacing face of two side laminating of the subassembly of adjusting luminance and with the butt face of the terminal surface laminating of the subassembly of adjusting luminance, the subassembly of adjusting luminance passes through the joint groove and constitutes an overall structure with frame piece, the subassembly of adjusting luminance when glass receives vibrations receives the restriction that the subassembly received frame piece and protection can not take place to collide with, strike or phenomenon such as slip, consequently can guarantee the stable function of the subassembly of adjusting luminance.

When the dimming glass is produced by adopting a method of sandwiching liquid crystal between two pieces of glass, the two sides of the dimming glass have obvious temperature difference, the liquid crystal functional layer is positioned in the middle interlayer part of the dimming glass and is influenced by the temperature difference between the two sides, and the working state of the liquid crystal functional layer can be changed, for example, the response speed is influenced. In addition, the liquid crystal functional layer can be compounded on the glass through the adhesive layer inevitably, the adhesive layers on the two sides are influenced by different temperatures, the volume change caused by the temperatures is different, uneven pressure can be generated on the middle liquid crystal functional layer in the volume change process, and finally, the light transmittance of each part of the liquid crystal functional layer is uneven, so that the use is influenced. According to the invention, the dimming assembly is prevented from directly contacting indoor and outdoor air through the first chamber and the second chamber, and under the heat insulation effect of the first chamber and the second chamber, the temperature difference between the second glass and the third glass is small, so that the first bonding layer and the second bonding layer are not easy to generate large volume change difference.

Through first buffering glue film, form elastic contact between the frame spare of the subassembly of adjusting luminance and stereoplasm, the great local pressure of production because the rigid contact between subassembly and the frame spare of adjusting luminance is avoided with the energy of absorption vibrations in-process to first buffering glue film, and first buffering glue film also enables the subassembly of adjusting luminance and the cooperation of joint groove is more perfect simultaneously, prevents that the subassembly of adjusting luminance is not hard up.
Furthermore, a second buffer glue layer is arranged between the outer end of the side frame part and the inner end of the spacing frame. The first buffer layer plays a role in buffering between the dimming assembly and the frame part, and integrally, the dimming assembly and the frame part form a dimming assembly integrated structure, at the moment, the dimming assembly integrated structure needs to interact with other assemblies, and when glass vibrates, mutual pressure action may be generated between the dimming assembly integrated structure and the spacing frame.
Furthermore, the limiting surface is provided with a temperature adjusting groove, and a heating element is arranged in the temperature adjusting groove.
Furthermore, the notch of the temperature adjusting groove corresponds to the position of the colloid clamping body.
