It includes a window frame, a vacuum glass assembly, and a sealing assembly. The sealing assembly includes an elastomer with a main cavity, a secondary cavity, and a flow channel, forming a closed, constant-volume fluid loop. The main cavity fits against the surface of the vacuum glass assembly, and the secondary cavity fits against its side sealing surface.

Description

Technical Field

[0001] This invention belongs to the field of building energy conservation technology, and in particular relates to an ultra-low energy consumption all-system energy-saving window with integrated vacuum insulation glass. Background Technology

[0002] With increasingly stringent requirements for building energy conservation, the thermal insulation, heat insulation, and airtightness of building envelopes are receiving growing attention. Windows, as components of the building envelope that combine lighting, ventilation, enclosure, and thermal insulation functions, directly impact building energy consumption due to their heat transfer performance, airtightness, watertightness, and long-term service stability. Especially in applications such as ultra-low energy buildings and near-zero energy buildings, windows not only need to have low heat transfer coefficients but also maintain stable sealing performance under long-term temperature fluctuations, wind pressure fluctuations, rain erosion, and installation stress.

[0003] Existing energy-saving windows typically reduce heat exchange within the window frame by employing thermally broken profiles, insulated glass, low-emissivity coated glass, composite sealing strips, and multi-layered sealing structures. Among these, vacuum glass, due to the low-pressure or vacuum insulation space created between the glass panes, effectively reduces gas conduction and convective heat transfer, and is therefore increasingly being used in high-performance energy-saving windows. Integrating vacuum glass components into the window frame can improve the overall thermal insulation performance of the window to a certain extent, meeting the demand for low-energy-consumption windows in the building energy conservation field.

[0004] However, compared to ordinary insulated or monopane glass, the edge area of ​​vacuum glass assemblies typically plays a crucial role in maintaining the vacuum state inside the glass and ensuring the reliability of the structural seal. After installation in the window frame, this edge area is often simultaneously subjected to the clamping force of the window frame, the pressing force of the seals, the weight of the glass itself, wind pressure loads, and the thermal expansion and contraction caused by the temperature difference between indoors and outdoors. Especially during long-term service of exterior windows, the different linear expansion characteristics between the window frame profiles, sealing materials, and glass materials can easily cause localized stress concentration at the edges of the vacuum glass assembly, thus affecting the sealing reliability and durability of the edge sealing area.

[0005] Most existing window sealing strips or rubber strips rely primarily on the elastic compression deformation of the material itself to create a seal. After the glass is installed in the window frame, the sealing strip is compressed and rebounds to prevent air, moisture, or rainwater from entering the installation gaps. While this type of structure can meet the sealing requirements of most doors and windows, its stress distribution is relatively passive, with the sealing pressure mainly derived from the initial compression during assembly. When the window is subjected to wind pressure fluctuations, minor displacement of the glass surface, or temperature cycles, the local compression state of the sealing strip is prone to change, making it difficult to continuously provide stable and directional compensating sealing pressure to the edge sealing area of ​​the vacuum glass assembly.

[0006] Furthermore, traditional elastic sealing structures typically deform along the direction of least resistance after being compressed. Some of this deformation may be absorbed by the installation gaps inside the window frame, the profile cavity, or the cavity of the sealing strip itself, resulting in insufficient effective clamping force acting on the edge of the vacuum glass assembly. Especially at the side sealing surfaces of the vacuum glass assembly, if the sealing pressure is unevenly distributed or rapidly decreases with changes in operating conditions, problems such as local micro-cracks, moisture intrusion, or uneven edge stress can easily occur, which is detrimental to the long-term stable use of vacuum glass assemblies in high-energy-efficiency windows.

[0007] On the other hand, ultra-low energy consumption windows typically require not only excellent thermal insulation performance from the glass itself, but also coordinated operation between the window frame, glass edges, sealing structure, drainage structure, and drying structure. While some existing window frames are equipped with drainage channels, thermal insulation structures, or drying structures, these structures are usually independently designed to drain accumulated water, reduce heat transfer through the profiles, or absorb localized moisture, making it difficult to effectively coordinate with the dynamic sealing compensation of the vacuum glass assembly edges. When outdoor temperatures change drastically or rainwater or moisture enters the window frame installation area, the edges of the vacuum glass assembly may still be affected by both temperature gradient changes and moisture accumulation, thus reducing the overall energy-saving performance and service reliability of the window.

[0008] Therefore, existing energy-saving windows with integrated vacuum glass still have room for improvement, especially in how to balance the overall energy-saving performance of the window frame with the reliability of the edge sealing of the vacuum glass assembly. Establishing a sealing structure between the window frame and the vacuum glass assembly that can adapt to assembly stress, wind pressure fluctuations, and temperature cycles, ensuring stable, directional, and consistent sealing compensation at the edges of the vacuum glass assembly during long-term use, is a pressing technical problem that needs to be solved in this field. Summary of the Invention

[0009] This invention overcomes the shortcomings of the prior art and provides an ultra-low energy consumption all-system energy-saving window with integrated vacuum insulation glass.

[0010] To achieve the above objectives, the technical solution adopted by the present invention is: an ultra-low energy consumption all-system energy-saving window integrating vacuum insulating glass, comprising:

[0011] A window frame, a vacuum glass assembly disposed inside the window frame, and a sealing assembly continuously disposed between the window frame and the edge of the vacuum glass assembly;

[0012] The sealing assembly includes an integrally formed elastomer, the elastomer having a main cavity, a secondary cavity, and a flow channel connecting the main cavity and the secondary cavity;

[0013] The force-bearing side wall of the main cavity is parallel to and attached to the plate surface of the vacuum glass assembly;

[0014] The expansion sidewall of the secondary cavity is attached to the side sealing surface of the vacuum glass assembly;

[0015] The main cavity, the secondary cavity, and the flow channel together constitute a closed constant volume fluid circuit, which is filled with fluid.

[0016] The window frame is provided with a mounting groove, and the side of the elastomer away from the vacuum glass assembly is embedded with a skeleton. The skeleton is snapped into the mounting groove to restrict the deformation of the elastomer into the window frame and to cause the secondary cavity to expand toward the side sealing surface.

[0017] The flow channel is provided with a damping structure, which is configured such that the forward flow resistance of the fluid from the main cavity to the secondary cavity is less than the reverse flow resistance from the secondary cavity back to the main cavity.

[0018] In a preferred embodiment of the present invention, the damping structure is integrally formed with the elastomer, and the damping structure is a unidirectional flexible microvalve pointing towards the secondary cavity or a tapered cross section.

[0019] In a preferred embodiment of the present invention, the fluid is an incompressible fluid, and the fluid is silicone oil or fluorinated liquid with a freezing point below -40°C and a kinematic viscosity change rate of less than 15% in the temperature range of -40°C to 60°C.

[0020] In a preferred embodiment of the present invention, the expansion sidewall of the secondary cavity is provided with a plurality of parallel extending sealing lips, and the sealing lips abut against the side sealing surface.

[0021] In a preferred embodiment of the present invention, the vacuum glass assembly includes an outdoor glass panel and an indoor glass panel, wherein the edges of the outdoor glass panel and the edges of the indoor glass panel are offset to form a stepped groove at the side sealing surface.

[0022] The expansion sidewall of the secondary cavity and the sealing lip are fitted into the stepped groove.

[0023] In a preferred embodiment of the present invention, the sealing assembly is composed of four straight segments of the elastomer joined together at the corners to form a rectangular frame structure;

[0024] The constant-volume fluid circuit within each segment of the elastic body is physically separated at the corner joint by a solid rubber block, ensuring that the fluids within the four segments of the elastic body are not interconnected.

[0025] In a preferred embodiment of the present invention, the window frame includes an exterior profile, an interior profile, and a thermal break strip connecting the two.

[0026] The insulation strip has a phase change energy storage chamber inside.

[0027] In a preferred embodiment of the present invention, the phase change energy storage chamber is filled with microcapsule phase change material to absorb the thermal shock during sudden changes in outdoor temperature and reduce the temperature gradient at the edge of the vacuum glass assembly.

[0028] In a preferred embodiment of the present invention, the interior of the indoor profile is provided with a drying chamber, and a molecular sieve is built into the drying chamber;

[0029] A vent is provided on the inner wall of the window frame, and the vent connects the drying chamber to the installation gap at the edge of the vacuum glass assembly.

[0030] In a preferred embodiment of the present invention, the outdoor profile and the sealing assembly form an equal pressure cavity, and the outdoor profile is provided with a drainage hole that connects the equal pressure cavity and the outdoor environment. The drainage hole is inclined downward in a direction from the inside to the outside.

[0031] This invention addresses the shortcomings of the prior art and has the following beneficial effects:

[0032] This invention places a sealing component between the window frame and the edge of the vacuum glass assembly, forming a closed, constant-volume fluid loop within the elastic body, consisting of a main cavity, a secondary cavity, and a flow channel. This ensures the main cavity adheres to the surface of the vacuum glass assembly, and the secondary cavity adheres to the side sealing surfaces. Therefore, when the vacuum glass assembly experiences changes in surface stress due to assembly, wind pressure, or temperature differences, the pressure on the main cavity is transmitted to the secondary cavity via the fluid, causing the secondary cavity to provide compensating compression to the side sealing surfaces, rather than relying solely on the initial compression of the sealing material to maintain a seal. Compared to existing sealing strips that primarily rely on passive elastic rebound for sealing, this invention transforms the surface stress into effective sealing pressure along the edge of the vacuum glass assembly, improving the sealing stability of the edge sealing area and further reducing the adverse effects of edge micro-cracks, moisture intrusion, and localized stress concentration on vacuum insulation performance.

[0033] This invention incorporates a frame embedded in the side of the elastomer facing away from the vacuum glass assembly, and the frame is engaged within the mounting groove of the window frame. The frame constrains the deformation of the elastomer toward the interior of the window frame, preventing the elastomer from randomly displaced into the mounting groove or the inner cavity of the window frame under pressure. Instead, it causes the secondary cavity to expand directionally toward the side sealing surface of the vacuum glass assembly. This structure effectively guides the fluid pressure and elastic deformation within the sealing assembly to the edge sealing area requiring compensation, directly improving the utilization rate of the sealing pressure. Compared to ordinary cavity sealing strips that tend to bulge toward areas of lower resistance under pressure, resulting in a dispersion of effective clamping force, this invention reduces sealing force loss, providing a more stable and concentrated sealing support for the edges of the vacuum glass assembly, thereby enhancing the edge sealing reliability of the window during long-term service.

[0034] This invention incorporates a damping structure within the flow channel, ensuring that the forward flow resistance from the main cavity to the secondary cavity is less than the reverse flow resistance from the secondary cavity back to the main cavity. This allows the sealing assembly to quickly establish edge compensation pressure when subjected to external pressure or glass surface displacement, while delaying the release of pressure within the secondary cavity after the external force weakens. Consequently, the compression of the side sealing surface by the secondary cavity has a certain degree of retention, preventing immediate and complete rebound as the instantaneous load disappears. Compared to existing elastic seals that are prone to repeated compression and rapid rebound under wind pressure fluctuations or temperature cycles, causing sealing pressure fluctuations, this invention reduces abrupt changes in the sealing state under dynamic operating conditions, improves the continuity of the edge seal of the vacuum glass assembly, and further mitigates the fatigue effects of repeated stress cycles on the edge sealing structure.

[0035] This invention designs the damping structure as a unidirectional flexible micro-valve or a gradually narrowing cross-section integrally molded with the elastomer, and selects an incompressible fluid that maintains minimal viscosity change even at low temperatures. This allows the constant-volume fluid circuit to maintain relatively stable pressure transmission and damping response over a wide temperature range. This design enables the sealing assembly to achieve asymmetric flow characteristics without relying on additional complex valves, reducing the number of assembly parts and lowering the risk of fluid flow imbalance due to temperature changes. Compared to ordinary sealing cavities that only provide elastic buffering and lack controlled pressure transmission, this invention can maintain a more stable compensating sealing capability in building environments with cold, hot, and large diurnal temperature variations, making it more suitable for long-term application in ultra-low energy building windows.

[0036] This invention features multiple parallel-extending sealing lips on the expansion sidewall of the secondary cavity, which abut against the side sealing surface of the vacuum glass assembly. When a stepped groove forms at the edge of the vacuum glass assembly, the secondary cavity and sealing lips are further fitted into the stepped groove. This fit ensures that the compensating expansion of the secondary cavity does not merely form a single line contact, but rather establishes a multi-level sealing interface through multiple sealing lips and a stepped fitting structure, while simultaneously providing flexible coverage and positioning support for the side sealing surface. Compared to the traditional planar abutment or single-layer pressing between the sealing strip and the glass edge, this invention extends the moisture entry path, improves the edge stress distribution, and reduces the localized impact on the edge sealing area when the vacuum glass assembly experiences minor movement within the window frame.

[0037] This invention configures the sealing assembly as a rectangular frame structure formed by four straight elastic body segments joined at the corners. Solid rubber blocks at the corner joints physically isolate the fluid within each elastic body segment, preventing communication between the fluids within the four segments. This structure ensures that when any side of the window is affected by wind pressure, installation deviations, or thermal deformation, only the constant-volume fluid loop on that side experiences a pressure response, preventing pressure crosstalk to other sides. Compared to a continuous fluid sealing structure, which may experience localized pressure dispersion, abnormal corner bulging, or delayed compensation response, this invention allows for more independent and controllable sealing compensation on each side, thereby improving the consistency and stability of the sealing state around the rectangular window.

[0038] This invention incorporates an exterior profile, an interior profile, and a thermal break strip connecting them within the window frame. A phase-change energy storage chamber is incorporated within the thermal break strip, enabling it to absorb or release some heat when the outdoor temperature changes abruptly, thus reducing the temperature gradient at the edge of the vacuum glass assembly. This structure does not simply rely on the thermal break strip to block thermal bridges; instead, it buffers edge thermal shocks through phase-change energy storage, preventing excessive thermal stress in the edge sealing area of ​​the vacuum glass assembly from arising due to sudden temperature changes. Compared to conventional thermally broken window frames that only focus on reducing heat conduction, this invention further considers the sensitivity of the vacuum glass assembly's edge sealing structure to temperature changes, which helps maintain the edge sealing life of the vacuum insulated glass and the overall energy-saving performance of the window.

[0039] This invention further incorporates drainage holes in the window frame, combined with a drying and humidity-regulating structure at the installation gaps, allowing rainwater or moisture entering the window frame edge area to be promptly drained or reduced, preventing it from lingering near the vacuum glass assembly edges and sealing components. This structure, working in conjunction with the aforementioned compensating sealing structure, ensures not only stable compression of the edge area but also operation in a low-humidity, low-water-accumulation environment. Compared to existing window frame designs where drainage, drying, and sealing structures are relatively independent and difficult to coordinate for ensuring the reliability of vacuum glass edges, this invention enhances the stability of the window system through pressure compensation, thermal shock buffering, and moisture control, making it more suitable for the long-term energy-saving and durability requirements of ultra-low-energy buildings.

Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] like Figures 1 to 3 As shown, an ultra-low energy consumption all-system energy-saving window integrating vacuum insulating glass includes: a window frame 1, a vacuum glass assembly 2 disposed inside the window frame 1, and a sealing assembly 3 continuously disposed between the edges of the window frame 1 and the vacuum glass assembly 2; the sealing assembly 3 includes an integrally formed elastomer 301, the elastomer 301 having a main cavity 3011, a secondary cavity 3012, and a flow channel 3013 connecting the main cavity 3011 and the secondary cavity 3012; the force-bearing side wall of the main cavity 3011 is parallel to and attached to the plate surface of the vacuum glass assembly 2; the expansion side wall of the secondary cavity 3012 is attached to the side sealing surface of the vacuum glass assembly 2; the main cavity 3011... 11. The secondary cavity 3012 and the flow channel 3013 together form a closed constant volume fluid circuit, which is filled with fluid. The window frame 1 is provided with a mounting groove. The elastic body 301 is embedded with a skeleton 302 on the side away from the vacuum glass assembly 2. The skeleton 302 is snapped into the mounting groove to limit the deformation of the elastic body 301 into the window frame 1 and to cause the secondary cavity 3012 to expand in a directional direction toward the side sealing surface. The flow channel 3013 is provided with a damping structure 4. The damping structure 4 is configured to make the forward flow resistance of the fluid from the main cavity 3011 to the secondary cavity 3012 less than the reverse flow resistance of the fluid flowing back from the secondary cavity 3012 to the main cavity 3011.

[0050] The core of this invention lies in the fact that the sealing component 3 is not merely used as an ordinary elastic sealing strip, but rather constructs a constant-volume fluid circuit capable of pressure transmission within the elastomer 301. Through the cooperation between the main cavity 3011, the secondary cavity 3012, the flow channel 3013, the skeleton 302, and the damping structure 4, the local pressure changes caused by assembly pressure, wind pressure, or temperature difference deformation in the direction of the vacuum glass assembly 2's plate surface are converted into compensating clamping force towards the side sealing surface of the vacuum glass assembly 2. In other words, the main cavity 3011 is used to sense pressure changes in the direction of the vacuum glass assembly 2's plate surface, the secondary cavity 3012 is used to form a sealing compensation for the side sealing surface of the vacuum glass assembly 2, the flow channel 3013 is used to establish a controlled fluid transmission path between the two, the skeleton 302 is used to constrain the ineffective deformation direction of the elastomer 301, and the damping structure 4 is used to ensure that the compensating pressure has a fast build-up and slow release retention characteristic. This allows the edge sealing area of ​​the vacuum glass assembly 2 to obtain more stable, directional, and continuous sealing support during long-term service.

[0051] The following, in conjunction with the accompanying drawings, provides a detailed description of the specific structure, assembly relationship, and working process of the window frame 1, the vacuum glass assembly 2, the sealing assembly 3, and the constant volume fluid circuit inside the sealing assembly 3.

[0052] Example 1:

[0053] like Figure 1 As shown, in this embodiment, the window frame 1 is a rectangular frame structure for supporting the vacuum glass assembly 2. The inner side of the window frame 1 forms an installation area to accommodate the edge of the vacuum glass assembly 2. The vacuum glass assembly 2 is disposed inside the window frame 1, with gaps reserved between its four edges and the window frame 1 for installing the sealing assembly 3. The sealing assembly 3 is continuously arranged along the circumference of the vacuum glass assembly 2, allowing the edge of the vacuum glass assembly 2 to form a flexible contact with the window frame 1 through the sealing assembly 3. Thus, the window frame 1 provides an overall installation reference and structural support, the vacuum glass assembly 2 provides heat insulation, light transmission, and enclosure functions, and the sealing assembly 3 undertakes edge sealing, stress buffering, and compensating compression functions between the window frame 1 and the vacuum glass assembly 2.

[0054] In this embodiment, the window frame 1 can adopt a thermally broken profile structure, with an installation groove on its inner side extending along the edge of the vacuum glass assembly 2. The installation groove is used to accommodate and limit the sealing assembly 3, so that the sealing assembly 3 can maintain a stable position after being installed in the window frame 1. The vacuum glass assembly 2 can include glass plates arranged opposite each other and a side sealing surface located at the edge of the glass plates. This side sealing surface is used to maintain the vacuum insulation state inside the vacuum glass assembly 2. Since the side sealing surface is adjacent to both the window frame 1 and the sealing assembly 3, it is easily affected by the clamping of the window frame 1, sealing compression, temperature difference deformation, and wind pressure. Therefore, in this embodiment, the main compensation area of ​​the sealing assembly 3 is arranged at this side sealing surface, so that the sealing assembly 3 not only supports the surface of the vacuum glass assembly 2, but also provides directional sealing compensation for the edge sealing area of ​​the vacuum glass assembly 2.

[0055] like Figure 2 and Figure 3 As shown, the sealing assembly 3 includes an elastomer 301, which is an integrally molded structure and can be made of EPDM rubber, silicone rubber, thermoplastic elastomer, or other weather-resistant elastic materials suitable for door and window sealing. The elastomer 301 extends along the edge of the vacuum glass assembly 2 and has a cross-sectional shape that adapts to the edge of the vacuum glass assembly 2. The side of the elastomer 301 near the surface of the vacuum glass assembly 2 forms a stress-bearing area for bearing the surface pressure; the side of the elastomer 301 near the side sealing surface of the vacuum glass assembly 2 forms a compensation area for expanding and pressing against the side sealing surface; and the side of the elastomer 301 away from the vacuum glass assembly 2 is used to mate with the mounting groove of the window frame 1.

[0056] The elastomer 301 has a main cavity 3011, a secondary cavity 3012, and a flow channel 3013. The main cavity 3011 is located on the side of the elastomer 301 closest to the surface of the vacuum glass assembly 2. The force-bearing side wall of the main cavity 3011 is parallel or nearly parallel to the surface of the vacuum glass assembly 2. The term "parallel fit" does not require the entire side wall of the main cavity 3011 to be completely flush with the surface of the vacuum glass assembly 2 at all points. Rather, it means that the force-bearing side wall of the main cavity 3011 extends along the surface direction of the vacuum glass assembly 2 and can be the first to sense pressure changes when the vacuum glass assembly 2 is subjected to surface pressure or undergoes slight surface displacement. Therefore, the surface force of the vacuum glass assembly 2 can be effectively transmitted to the main cavity 3011, making the main cavity 3011 the pressure input point in a constant-volume fluid circuit.

[0057] The secondary cavity 3012 is located on the side of the elastomer 301 near the side sealing surface of the vacuum glass assembly 2. The expansion sidewall of the secondary cavity 3012 is in contact with or approximately in contact with the side sealing surface of the vacuum glass assembly 2. Here, "in contact" refers to the expansion direction of the secondary cavity 3012 primarily towards the side sealing surface of the vacuum glass assembly 2, rather than only compressing and rebounding along the surface direction of the vacuum glass assembly 2. When subjected to fluid pressure from the main cavity 3011, the expansion sidewall of the secondary cavity 3012 can flexibly expand towards the side sealing surface, thereby forming compensating compression in the edge sealing area of ​​the vacuum glass assembly 2.

[0058] The flow channel 3013 connects the main cavity 3011 and the secondary cavity 3012. The flow channel 3013 can bend and extend along the cross-section of the elastomer 301, or it can be arranged as a short channel between adjacent areas of the main cavity 3011 and the secondary cavity 3012. The main cavity 3011, the secondary cavity 3012, and the flow channel 3013 together form a closed constant-volume fluid circuit. This constant-volume fluid circuit is isolated from the external environment and does not communicate with the external space of the window frame 1 or the internal space of the vacuum glass assembly 2 under normal service conditions. After the elastomer 301 is formed, fluid can be injected into the constant-volume fluid circuit through the reserved injection channel. After injection, the injection channel is sealed by heat fusion, glue sealing, vulcanization sealing, or insert sealing, so that the main cavity 3011, the secondary cavity 3012, and the flow channel 3013 form a stable and closed fluid-containing space. The above-mentioned injection channel is only a process structure in the manufacturing process and is not shown separately in the accompanying drawings of this embodiment.

[0059] The fluid filling the constant-volume fluid circuit is preferably an incompressible fluid. By using an incompressible fluid, when the main cavity 3011 is compressed due to the pressure in the direction of the vacuum glass assembly 2, the effective volume of the main cavity 3011 decreases. The fluid will not be significantly compressed like a gas, but will be forced to flow through the flow channel 3013 to the secondary cavity 3012, causing the secondary cavity 3012 to undergo corresponding volume compensation and expansion deformation. Thus, the pressure change felt by the main cavity 3011 can be transferred to the secondary cavity 3012 with high efficiency, rather than being completely absorbed by the overall deformation of the elastomer 301 itself. For example, the fluid can be silicone oil or fluorinated liquid, preferably silicone oil or fluorinated liquid with a freezing point below -40°C and a kinematic viscosity change rate of less than 15% in the temperature range of -40°C to 60°C. In this way, even if the energy-saving window is in a cold region, a hot summer region, or an application environment with a large day-night temperature difference, the constant-volume fluid circuit can still maintain a relatively stable flow damping and pressure transmission capability, avoiding imbalance in the compensation sealing response caused by fluid stagnation at low temperatures or excessive thinning at high temperatures.

[0060] To prevent the elastomer 301 from bulging disorderly into the window frame 1 under pressure, this embodiment embeds a skeleton 302 on the side of the elastomer 301 facing away from the vacuum glass assembly 2. The skeleton 302 extends along the length of the elastomer 301 and is at least partially embedded in the elastomer 301, forming an integral fit structure between the skeleton 302 and the elastomer 301. The skeleton 302 can be embedded simultaneously during the extrusion molding, injection molding, or compression molding of the elastomer 301, or it can be combined with the elastomer 301 after molding through embedding, covering, or secondary molding. The outer shape of the skeleton 302 matches the mounting groove of the window frame 1, so that the sealing assembly 3 can be snapped into the mounting groove by the skeleton 302 during installation.

[0061] Specifically, the outer wall of the frame 302 is provided with barbed protrusions or dovetail protrusions, and the inner wall of the mounting groove of the window frame 1 is provided with a groove that matches the protrusions or protrusions. When the frame 302 is pressed into the mounting groove, the two form a mechanical interlock.

[0062] After the skeleton 302 is engaged in the mounting groove of the window frame 1, it can effectively resist the reaction force generated during fluid transfer and limit the yielding deformation of the elastomer 301 towards the interior of the window frame 1. Specifically, when the main cavity 3011 is subjected to pressure from the surface of the vacuum glass assembly 2, without the restraint of the skeleton 302, the elastomer 301 may bulge along the gap direction inside the mounting groove of the window frame 1, causing some pressure to be ineffectively dissipated. By placing the skeleton 302 on the side of the elastomer 301 away from the vacuum glass assembly 2 and engaging the skeleton 302 with the mounting groove, the deformation space on the back side of the elastomer 301 is constrained. The fluid pressure and elastic deformation tendency generated after the main cavity 3011 is pressed are forced to be transmitted towards the side where the secondary cavity 3012 is located, thereby causing the secondary cavity 3012 to expand directionally towards the side sealing surface of the vacuum glass assembly 2.

[0063] like Figure 3 As shown, a damping structure 4 is provided within the flow channel 3013. The damping structure 4 can be integrally formed with the elastomer 301 and is located on the fluid flow path between the main cavity 3011 and the secondary cavity 3012. The damping structure 4 is not used to completely block the fluid flow, but rather to ensure that the forward flow resistance of the fluid from the main cavity 3011 to the secondary cavity 3012 is less than the reverse flow resistance of the fluid flowing back from the secondary cavity 3012 to the main cavity 3011. With this arrangement, when the main cavity 3011 is pressurized, the fluid can smoothly enter the secondary cavity 3012 from the main cavity 3011, allowing the secondary cavity 3012 to quickly establish compensating compression on the side sealing surface; when the external pressure decreases or disappears, the fluid in the secondary cavity 3012 cannot immediately flow back to the main cavity 3011 in large quantities under the action of the damping structure 4, thus allowing the compression effect of the secondary cavity 3012 on the side sealing surface to have a certain holding time.

[0064] In one specific implementation, the damping structure 4 can be a unidirectional flexible microvalve pointing towards the secondary cavity 3012. The root of this unidirectional flexible microvalve is connected to the inner wall of the flow channel 3013, and the free end extends towards the secondary cavity 3012. When fluid flows from the main cavity 3011 to the secondary cavity 3012, the fluid pressure pushes the unidirectional flexible microvalve to swing or open towards the secondary cavity 3012, increasing the effective flow cross-section of the flow channel 3013, allowing the fluid to enter the secondary cavity 3012 more quickly. When the fluid attempts to flow back from the secondary cavity 3012 to the main cavity 3011, the reverse fluid pressure pushes the unidirectional flexible microvalve close to the inner wall of the flow channel 3013 or blocks a local section of the flow channel 3013, reducing the effective flow cross-section and decreasing the reverse flow velocity. Thus, without adding independent valves, a controlled fluid passage with different forward and reverse flow resistances can be formed inside the elastomer 301.

[0065] In another specific implementation, the damping structure 4 can also be a gradually tapered cross-section. This gradually tapered cross-section can be configured as an asymmetric flow channel structure that gradually transitions along the direction from the main cavity 3011 to the secondary cavity 3012. Specifically, the gradually tapered cross-section is funnel-shaped, with a smoothly transitioning guide surface on the side near the main cavity 3011 and an abrupt step or sharp-angled flow-blocking wall perpendicular to the fluid flow direction on the side near the secondary cavity 3012. This allows the fluid to experience a relatively gentle guiding effect along the guide surface when flowing forward, while impacting the abrupt step or sharp-angled flow-blocking wall during reverse flow, generating eddies and thus experiencing strong local contraction resistance and energy loss. When using the gradually tapered cross-section form, the damping structure 4 can be integrally molded with the elastomer 301 in the same mold, eliminating the need for additional micro-valve components, making it suitable for continuous extrusion or compression molding processes of the sealing assembly 3. The aforementioned unidirectional flexible microvalve and the cross-sectional tapered nozzle can be selected individually or combined within the flow channel 3013 to adjust the response speed of the fluid circuit according to different window specifications, sealing pressure requirements, or usage environment.

[0066] The assembly process in this embodiment can be performed as follows: First, the sealing component 3 is arranged along the inner installation area of ​​the window frame 1, so that the frame 302 corresponds to the installation groove of the window frame 1, and the frame 302 is pressed into the installation groove to complete the snap-fit; then, the vacuum glass component 2 is installed inside the window frame 1, so that the plate surface of the vacuum glass component 2 fits against the force-bearing side wall surface of the main cavity 3011, and the side sealing surface of the vacuum glass component 2 fits against the expansion side wall surface of the secondary cavity 3012. After assembly, the sealing component 3 is in the initial pre-compression state, the fluid in the main cavity 3011 and the secondary cavity 3012 is in a balanced distribution state, and the elastic body 301 provides flexible support for the plate surface and side sealing surface of the vacuum glass component 2.

[0067] When the energy-saving window is subjected to outdoor wind pressure, the surface of the vacuum glass assembly 2 may experience slight displacement or localized pressure, compressing the stress-bearing side wall of the main cavity 3011. Since the main cavity 3011, secondary cavity 3012, and flow channel 3013 form a closed, constant-volume fluid loop, when the effective volume of the main cavity 3011 decreases, the fluid in the main cavity 3011 flows along the flow channel 3013 towards the secondary cavity 3012. At this time, the damping structure 4 is in a state conducive to positive flow, allowing the fluid to enter the secondary cavity 3012 more quickly, causing the expansion side wall of the secondary cavity 3012 to bulge towards the side sealing surface of the vacuum glass assembly 2. The expansion of the secondary cavity 3012 is not a free deformation without direction, but rather, under the constraint of the frame 302 and the window frame 1 mounting groove, it mainly occurs towards the side sealing surface, thus converting the pressure change in the surface direction into compensating sealing pressure on the edge sealing area of ​​the vacuum glass assembly 2.

[0068] When the wind pressure decreases, the surface of the vacuum glass assembly 2 recovers, or the temperature difference between indoors and outdoors tends to level off, the fluid in the secondary cavity 3012 tends to flow back into the main cavity 3011 under the rebound action of the elastic body 301. At this time, the damping structure 4 generates a large resistance to the reverse flow, preventing the fluid in the secondary cavity 3012 from instantly returning to the main cavity 3011. The secondary cavity 3012 can thus maintain a tight seal on the side sealing surface for a certain period of time, preventing the sealing pressure from dropping rapidly due to the disappearance of the external instantaneous load. Through this process, the sealing assembly 3 can provide smoother and more continuous edge sealing compensation under dynamic conditions such as wind pressure fluctuations, temperature difference cycles, and micro-displacement of the glass surface.

[0069] Furthermore, the expansion sidewall of the secondary cavity 3012 is provided with multiple parallel extending sealing lips 6, which abut against the side sealing surface of the vacuum glass assembly 2. The sealing lips 6 can be integrally formed with the elastomer 301 and extend continuously along the length direction of the sealing assembly 3. The multiple sealing lips 6 can be arranged sequentially along the thickness direction of the vacuum glass assembly 2, so that when the secondary cavity 3012 applies compensating pressure to the side sealing surface, the multiple sealing lips 6 can abut against different areas of the side sealing surface respectively, forming multiple sealing contact interfaces. Compared with the sealing method of a single contact surface, multiple sealing lips 6 can extend the moisture entry path, and when one sealing lip 6 is locally subjected to pressure changes, the other sealing lips 6 continue to maintain the sealing state, improving the sealing redundancy of the side sealing surface.

[0070] In this embodiment, the free end of the sealing lip 6 can be configured as a flexible thin-walled structure inclined towards the side sealing surface of the vacuum glass assembly 2. During assembly of the vacuum glass assembly 2, the sealing lip 6 first contacts the side sealing surface and undergoes elastic bending. When the sub-cavity 3012 expands due to fluid entry, the expanded sidewall of the sub-cavity 3012 pushes the sealing lip 6 further against the side sealing surface, causing the contact pressure of the sealing lip 6 to dynamically increase with the pressure change within the sub-cavity 3012. Therefore, the sealing lip 6 does not simply rely on the initial compression during assembly, but can withstand the compensating expansion pressure of the sub-cavity 3012, resulting in a more stable multi-stage seal on the side sealing surface.

[0071] Through the above structure, the window frame 1, vacuum glass assembly 2, and sealing assembly 3 in this embodiment form a clear synergistic relationship: the window frame 1 provides back constraint to the sealing assembly 3 through the mounting groove and the skeleton 302; the vacuum glass assembly 2 inputs pressure changes to the main cavity 3011 through the plate surface; the main cavity 3011 transmits pressure to the secondary cavity 3012 through fluid; the secondary cavity 3012 expands directionally towards the side sealing surface under the shape-limiting effect of the skeleton 302; the damping structure 4 delays the pressure release in the secondary cavity 3012; and the sealing lip 6 transforms the expansion of the secondary cavity 3012 into a multi-contact seal. The above components do not function in isolation but work together to complete the transformation process from plate surface stress to edge compensation sealing, enabling the edge sealing area of ​​the vacuum glass assembly 2 to maintain high sealing reliability under complex service conditions.

[0072] Example 2:

[0073] Based on Embodiment 1, this embodiment further optimizes the mating structure between the edge of the vacuum glass assembly 2 and the sealing assembly 3. The vacuum glass assembly 2 includes an outdoor glass panel and an indoor glass panel. The edges of the outdoor glass panel and the indoor glass panel are offset to form a stepped groove at the side sealing surface of the vacuum glass assembly 2. This stepped groove is continuously or segmented along the circumferential edge of the vacuum glass assembly 2, with its opening facing the direction of the sealing assembly 3, so that the secondary cavity 3012 and the sealing lip 6 in the sealing assembly 3 can extend into and fit into the stepped groove.

[0074] Specifically, a vacuum insulation space is formed between the outdoor and indoor glass panels through an edge sealing structure, with the side sealing surface located at the edge region of the two glass panels. Since the side sealing surface of the vacuum glass assembly 2 is crucial for maintaining its vacuum insulation performance, this embodiment does not simply have the sealing assembly 3 press against the outer surface of the vacuum glass assembly 2. Instead, by misaligning the edges of the outdoor and indoor glass panels, the side sealing surface forms a stepped groove capable of accommodating the expansion sidewall of the secondary cavity 3012 and the sealing lip 6. Thus, the sealing assembly 3's action on the edge of the vacuum glass assembly 2 changes from simple outer surface contact to a fitted, compensating seal on the side sealing surface and its adjacent stepped region.

[0075] In the assembled state, at least part of the expansion sidewall of the secondary cavity 3012 enters the stepped groove, and multiple sealing lips 6 abut against different contact areas within the stepped groove. The sealing lips 6 can extend continuously along the length of the sealing assembly 3 and are spaced apart along the thickness of the vacuum glass assembly 2; the free ends of each sealing lip 6 can be inclined toward the inner wall of the stepped groove, so that when the vacuum glass assembly 2 is installed into the window frame 1, the sealing lips 6 can first undergo elastic bending and form an initial fit. After assembly, the secondary cavity 3012 is located outside the side sealing surface. When the main cavity 3011 is pressurized and fluid is introduced into the secondary cavity 3012 through the flow channel 3013, the expansion sidewall of the secondary cavity 3012 pushes the sealing lips 6 further against the inner wall of the stepped groove, so that the multiple sealing lips 6 can enhance the fit as the pressure inside the secondary cavity 3012 increases.

[0076] Through the cooperation of the stepped groove and the sealing lip 6, the sealing path of the sealing component 3 to the edge of the vacuum glass component 2 is extended. If water vapor or rainwater wants to enter the vicinity of the side sealing surface, it needs to cross multiple contact interfaces formed by the sealing lips 6 in sequence. Even if the contact pressure of one of the sealing lips 6 decreases due to local assembly errors, slight deviations of the glass edge, or decreased elasticity after long-term compression, the other sealing lips 6 can still continue to abut against the inner wall of the stepped groove, thereby maintaining the overall sealing state at the side sealing surface. At the same time, the stepped groove also has a certain limiting effect on the secondary cavity 3012 and the sealing lip 6, which can reduce the shear impact on the side sealing surface when the vacuum glass component 2 moves slightly within the window frame 1.

[0077] In this embodiment, the expansion sidewall of the secondary cavity 3012 is fitted into the stepped groove. This does not mean that the secondary cavity 3012 needs to completely fill the stepped groove, but rather that the secondary cavity 3012 can form a relative positioning relationship with the stepped groove in an unpressurized or initially pre-pressurized state, and can generate compensating displacement toward the inner wall of the stepped groove when it expands under pressure. Thus, the expansion space of the secondary cavity 3012 is guided by the stepped groove, and the fluid pressure in the secondary cavity 3012 can be more concentratedly converted into a clamping force toward the side sealing surface, avoiding the secondary cavity 3012 from bulging in an ineffective direction and weakening the edge sealing effect.

[0078] Furthermore, the multiple sealing lips 6 can be configured as multi-stage flexible lips arranged sequentially from the side closest to the outside to the side closest to the inside. The sealing lips 6 near the outside are mainly used to prevent rainwater, dust, and outdoor air from entering the stepped groove; the sealing lips 6 near the middle are mainly used to maintain the compensating contact pressure when the sub-cavity 3012 expands; and the sealing lips 6 near the inside are mainly used to prevent residual moisture from further entering the vicinity of the side sealing surface of the vacuum glass assembly 2. Although each sealing lip 6 can have the same material and structure, and its tilt angle or thickness can be appropriately adjusted according to its position, they all form an integral fit with the expansion side wall of the sub-cavity 3012, enabling it to withstand the compensating expansion pressure of the sub-cavity 3012.

[0079] In this embodiment, the sealing assembly 3 can be further configured as a rectangular frame structure formed by four straight elastic bodies 301 joined at the corners. The four straight elastic bodies 301 are arranged corresponding to the upper edge, lower edge, left edge, and right edge of the vacuum glass assembly 2, respectively. Each elastic body 301 independently forms a constant-volume fluid circuit consisting of a main cavity 3011, a secondary cavity 3012, and a flow channel 3013. Adjacent elastic bodies 301 are joined together at the corners, and the constant-volume fluid circuits within each elastic body 301 are physically isolated at the corner joints by solid rubber blocks, so that the fluids within the four elastic bodies 301 are not interconnected.

[0080] Specifically, the solid rubber block can be embedded between the ends of two adjacent elastomer segments 301 during corner splicing, or it can form a sealed bond with two adjacent elastomer segments 301 through secondary vulcanization, adhesive bonding, hot pressing, or molding. The solid rubber block fills and seals the main cavity 3011, secondary cavity 3012, and flow channel 3013 at the ends of each elastomer segment 301, so that the constant volume fluid circuit within each elastomer segment 301 remains closed within its own length and does not connect with each other at the four corners of the window frame 1. In this way, the main cavity 3011, secondary cavity 3012, and flow channel 3013 on each side constitute a relatively independent pressure response unit.

[0081] When a side of the vacuum glass assembly 2 is subjected to significant local wind pressure, assembly deviation, or temperature-induced deformation, the corresponding main cavity 3011 is compressed. Fluid flows from the main cavity 3011 to the secondary cavity 3012 only within the constant-volume fluid circuit corresponding to that side, causing the secondary cavity 3012 to compensate for the sealing surface of the corresponding side. Because the solid rubber block at the corner joint blocks the fluid communication between the various elastic body sections 301, the pressure change on this side will not be transmitted to other sides through the circumferential fluid circuit, nor will it cause unnecessary bulging of the secondary cavities 3012 on other sides. Therefore, the sealing compensation of each side can be independently established according to its respective operating conditions, avoiding pressure crosstalk, local pressure dispersion, or abnormal corner expansion problems that may occur in a continuous fluid structure.

[0082] Meanwhile, even after the four linear elastomers 301 are spliced ​​at the corners to form a rectangular frame structure, they can still create a continuous seal along the circumferential edge of the vacuum glass assembly 2. The solid rubber blocks at the corners not only serve as fluid barriers but also provide solid support for the corner splicing area, preventing the corners from becoming weak points due to the continuous extension of the cavity. In this way, the sealing assembly 3 can maintain the integrity of the circumferential installation while enabling independent response of the fluid circuits on each side, thereby improving the sealing stability of the rectangular window under stress conditions in different directions.

[0083] Example 3:

[0084] Based on Embodiment 1 or Embodiment 2, this embodiment further optimizes the heat insulation, humidity regulation and drainage structure of the window frame 1, so that the window frame 1 is not only an installation carrier for the vacuum glass assembly 2, but also constitutes a whole-system energy-saving window structure suitable for ultra-low energy consumption buildings together with the sealing assembly 3.

[0085] Window frame 1 includes an exterior profile, an interior profile, and a thermal break strip connecting the exterior and interior profiles. The exterior profile is located closer to the outdoor environment, and the interior profile is located closer to the indoor environment. The thermal break strip is positioned between the exterior and interior profiles to reduce heat transfer between them. Through this thermal break structure, window frame 1 can reduce the thermal bridging effect between the interior and exterior profiles, thereby improving the overall thermal insulation performance of the energy-saving window.

[0086] Unlike ordinary thermal insulation strips that rely solely on the low thermal conductivity of the material for insulation, this embodiment incorporates a phase change energy storage chamber within the thermal insulation strip, filled with microcapsule phase change material. The microcapsule phase change material can be a phase change core material with a phase change temperature range and a microcapsule wall material encapsulating the phase change core material.

[0087] To adapt to the service environment of building windows, the phase change temperature range of the phase change core material is preferably 15°C to 30°C. For example, the phase change core material can be one or more mixtures of paraffin wax, higher fatty acids (such as stearic acid and palmitic acid), or polyethylene glycol; the microcapsule wall material can be polymethyl methacrylate or melamine resin.

[0088] By selecting materials within the specific phase change temperature range, it can absorb some heat when the outdoor temperature rises rapidly (e.g., exceeding 25°C) and release some heat when the outdoor temperature decreases. Since the phase change energy storage chamber is located between the outdoor and indoor profiles and adjacent to the installation area of ​​the edge of the vacuum glass assembly 2, its heat absorption or release process can buffer the temperature abrupt change in the edge area of ​​the window frame 1 and reduce the magnitude of the temperature gradient change at the edge of the vacuum glass assembly 2.

[0089] Specifically, under conditions of summer sunlight or sudden increases in outdoor temperature, the outdoor profile tends to heat up before the indoor profile, resulting in a faster temperature rise in the edge area of ​​the window frame 1 near the outdoor side. If this temperature change is directly transmitted to the vicinity of the side sealing surface of the vacuum glass assembly 2, it may create a large instantaneous temperature gradient at the edge of the vacuum glass assembly 2. By incorporating a phase change energy storage chamber inside the thermal insulation strip, the microcapsule phase change material can absorb some heat during the temperature rise phase, slowing down the rate at which heat is transferred from the outdoor side to the edge of the vacuum glass assembly 2. Correspondingly, during nighttime cooling or in cold environments, the microcapsule phase change material can release some of the stored heat, making the temperature change in the edge area of ​​the window frame 1 more gradual. Therefore, the edge sealing area of ​​the vacuum glass assembly 2 is less prone to excessive thermal stress due to short-term temperature changes.

[0090] The phase change energy storage chamber and the sealing assembly 3 work synergistically. The sealing assembly 3 achieves dynamic compensation sealing under mechanical stress conditions through the main cavity 3011, the secondary cavity 3012, the flow channel 3013, the skeleton 302, and the damping structure 4; the phase change energy storage chamber reduces temperature abrupt changes at the edge of the vacuum glass assembly 2 from a thermal environment perspective. Together, they ensure that the side sealing surface of the vacuum glass assembly 2 receives stable compression compensation while remaining in a relatively stable temperature change environment, thereby reducing the risk of failure at the edge sealing surface due to stress concentration, inconsistent thermal expansion and contraction, or fluctuations in sealing pressure.

[0091] Furthermore, a drying chamber is provided inside the interior profile, and a molecular sieve is placed inside the drying chamber; a vent is provided on the inner wall of the window frame 1, and the vent connects the drying chamber to the installation gap at the edge of the vacuum glass assembly 2. The installation gap is the space formed between the edge of the vacuum glass assembly 2 and the inner installation area of ​​the window frame 1, and the sealing assembly 3 is located in or near the installation gap.

[0092] To prevent the sealing component 3 from blocking the vent, air guide grooves are provided circumferentially or at intervals on the side of the frame 302 opposite to the elastomer 301, or on the inner wall of the window frame 1. These air guide grooves connect the side sealing surface area of ​​the vacuum glass assembly 2 with the vent, allowing moisture in the installation gap to bypass the solid obstruction of the sealing component 3 and smoothly enter the drying chamber through the air guide grooves and the vent. Since this area is close to the side sealing surface of the vacuum glass assembly 2, long-term moisture accumulation may affect the service stability of the sealing material and increase the risk of moisture seeping into the vicinity of the side sealing surface.

[0093] By incorporating a drying chamber and vents, moisture within the installation gaps can enter the drying chamber through the vents and be adsorbed by the molecular sieves within. The vents can be configured as multiple spaced-apart small holes or slits to ensure slow air exchange while preventing large amounts of water vapor or liquid water from directly entering the drying chamber. The molecular sieves can be placed in the drying chamber in granular, strip-like, or packaged form and can be arranged in sections along the length of the window frame 1. This allows the window frame 1 to continuously reduce humidity within the installation gaps at the edges of the vacuum glass assembly 2 during long-term service, maintaining a relatively dry environment near the sealing assembly 3 and the side sealing surfaces.

[0094] A pressure equalization chamber can also be formed between the outdoor profile and the sealing component 3. The outdoor profile has a drainage hole 5 connecting the pressure equalization chamber to the outdoor environment, and the drainage hole 5 is inclined downwards from the inside out. The pressure equalization chamber is located on the outdoor side of the window frame 1 and is used to contain rainwater or condensate that may enter the outdoor installation area of ​​the window frame 1, and to discharge it to the outdoor environment through the drainage hole 5. The drainage hole 5 adopts a downward inclined structure from the inside out, allowing the water in the pressure equalization chamber to drain smoothly to the outside under gravity, while reducing the possibility of outdoor rainwater reversing and entering the pressure equalization chamber through the drainage hole 5.

[0095] Under conditions of rain erosion or outdoor wind pressure fluctuations, a small amount of water vapor or rainwater may enter the area between the outdoor profile and the sealing component 3. In this case, the pressure equalization chamber acts as an outer buffer space, preventing water entering this area from directly affecting the side sealing surface of the vacuum glass assembly 2; the drainage hole 5 promptly drains the water accumulated in the pressure equalization chamber, preventing water from stagnating near the sealing component 3 for a long time. Since the drainage hole 5 is connected to the outdoor environment, the pressure equalization chamber can also reduce the continuous pressure difference effect of outdoor wind pressure on the installation gap to a certain extent, reducing the possibility of rainwater seeping into the depths of the vacuum glass assembly 2 under pressure difference.

[0096] A moisture control path is formed between the drying chamber, the vent, the isobaric chamber, and the drain hole 5. For liquid water, the isobaric chamber and drain hole 5 prioritize collection and discharge; for residual moisture, the molecular sieve in the vent and drying chamber achieves slow adsorption and humidity regulation. In this way, the window frame 1 can reduce the moisture load on the edge of the vacuum glass assembly 2 from both external drainage and internal humidity regulation. Compared with a window frame that only has ordinary drain holes, the window frame 1 in this embodiment can more effectively serve the long-term reliability of the side sealing surface of the vacuum glass assembly 2.

[0097] In the overall operation of this embodiment, when the outdoor temperature changes abruptly, the microcapsule phase change material in the phase change energy storage chamber absorbs or releases heat, slowing down the transfer of heat from the window frame 1 to the edge of the vacuum glass assembly 2. When external wind pressure or micro-displacement of the glass surface puts pressure on the main cavity 3011, the fluid in the main cavity 3011 enters the secondary cavity 3012 through the flow channel 3013. Under the limiting effect of the skeleton 302, the secondary cavity 3012 expands directionally towards the side sealing surface and forms multiple compensating seals through the sealing lip 6. When rainwater or moisture enters the edge area of ​​the window frame 1, the equal pressure chamber and drainage hole 5 discharge the liquid water, and the drying chamber and vent reduce the residual humidity in the installation gap. The above processes work together in three directions—thermal shock buffering, mechanical pressure compensation, and moisture emission control—to protect the edge area of ​​the vacuum glass assembly 2, enabling the vacuum glass assembly 2 to maintain a stable sealing state and thermal insulation performance for a long time in the ultra-low energy consumption window.

[0098] Therefore, in this embodiment, the window frame 1 provides directional shaping conditions for the sealing assembly 3 through the mounting groove and the skeleton 302, improves the thermal environment at the edge of the vacuum glass assembly 2 through the phase change energy storage chamber, and improves the humid environment at the edge of the vacuum glass assembly 2 through the drying chamber and the drainage hole 5; the sealing assembly 3 forms a dynamic compensation seal with retention on the side sealing surface through the constant volume fluid circuit and the damping structure 4. All the structures cooperate with each other around the common goal of reliable edge sealing of the vacuum glass assembly 2, so that the energy-saving window can form a synergistic effect of the whole system in terms of thermal insulation, edge sealing, resistance to wind pressure fluctuations, resistance to temperature difference cycles, and moisture prevention and drainage.
