Abstract
Description
Technical Field
[0001] This application relates to the field of door and window equipment technology, specifically to a high-insulation and sealing structure door and window. Background Technology
[0002] With the continuous improvement of building energy efficiency standards and people's increasing emphasis on living comfort, aluminum alloy doors and windows not only bear the basic functions of ventilation and lighting in building structures, but also play an important role in thermal insulation and energy saving. However, most aluminum alloy door and window products in the current technology still have many shortcomings in terms of thermal insulation and sealing performance, especially in the following two aspects: First, the thermal insulation performance is poor. Due to the high thermal conductivity of aluminum alloy itself, if a reasonable thermal insulation structure is not set inside the window sash and frame, it is easy to cause serious heat conduction, resulting in heat loss from the room or heat intrusion from the outside, thereby increasing energy consumption and reducing the overall thermal performance of the building. Second, the sealing performance is difficult to maintain for a long time. During long-term opening and closing, the sealing structure of doors and windows is prone to loosening, displacement, aging, and other problems. Especially at the joint between the window sash and the frame, if the sealing design is unreasonable or the sealing material is not resistant to compression fatigue, it is easy to form air leakage and water leakage paths, which not only affects the service life of the doors and windows, but also further weakens their thermal insulation effect.

[0026] The technical solutions shown in this application will be described in detail below through specific embodiments. It should be noted that the order of description of the following embodiments is not intended to limit the priority of the embodiments.
[0027] Please refer to Figures 1 to 3The high-insulation and sealing structure door and window of this application embodiment includes a composite window frame 1 and a movable window sash 2 disposed on the composite window frame 1. The movable window sash 2 opens / closes relative to the composite window frame 1. The movable window sash 2 is equipped with composite glass 3 to realize the door and window function.
[0028] In the specific implementation process, the movable window sash 2 includes a first frame 21, a second frame 22, a connecting profile 23, and a first sealing body 24. The first frame 21 and the second frame 22 are arranged opposite to each other, and the connecting profile 23 and the first sealing body 24 are arranged at intervals. The two ends of the connecting profile 23 and the first sealing body 24 are respectively connected to the first frame 21 and the second frame 22, thereby forming a frame-type edge-sealing structure, which is used to stably support the composite glass 3 embedded therein and enhance the overall structural strength and deformation resistance of the window sash.
[0029] Furthermore, the composite window frame 1 includes a first profile 11, a second profile 12, an intermediate connecting plate 13, and a second sealing body 14. The first profile 11 and the second profile 12 are arranged opposite to each other, and the two intermediate connecting plates 13 are arranged at intervals. The two ends of the intermediate connecting plate 13 are respectively connected to the first profile 11 and the second profile 12, thereby forming a frame-type edge-wrapping structure for stable support and fixation.
[0030] Among them, the connecting profile 23 and the intermediate connecting plate 13 can be used to provide mechanical connection and structural reinforcement for doors and windows. They can be made of aluminum alloy profiles or other high-strength lightweight materials to enhance connection stability.
[0031] The second sealing body 14 is connected to the intermediate connecting plate 13 near the first sealing body 24. After the movable window sash 2 is closed relative to the composite window frame 1, the first sealing body 24 and the second sealing body 14 abut against each other to form a reliable seal.
[0032] The movable window sash 2 is provided with a first composite insulation layer 41, which is located between the first frame 21 and the second frame 22 and abuts against the connecting profile 23 and the first sealing body 24 respectively. The composite window frame 1 is provided with a second composite insulation layer 42, which is located between the first profile 11 and the second profile 12 and abuts against the two intermediate connecting plates 13 respectively.
[0033] Thus, one side of the first composite insulation layer 41 abuts against the connecting profile 23, and the other side abuts against the first sealing body 24. While achieving a stable fit, it further enhances the sealing performance and overall thermal performance of the internal structure of the window sash. This structural layout effectively cuts off the thermal bridge path, reduces the overall thermal conductivity of the window sash body, and improves the insulation effect of the door and window. Similarly, the second composite insulation layer 42 is located between the first profile 11 and the second profile 12, and abuts against the two intermediate connecting plates 13 respectively, thereby forming a complete and continuous insulation structure inside the window frame. As a result, the window frame body significantly improves its thermal resistance while ensuring structural strength, and reduces problems such as condensation and cooling caused by temperature differences. In other words, the combination of the first composite insulation layer 41 and the second composite insulation layer 42 improves the insulation effect of the door and window.
[0034] In one example, both the first composite insulation layer 41 and the second composite insulation layer 42 include a polyester fiber felt layer 51, a polyurethane foam layer 52 and a flame-retardant nonwoven fabric layer 53 stacked sequentially.
[0035] Among them, the flame-retardant non-woven fabric layer 53 of the first composite insulation layer 41 abuts against the first sealing body 24, and the polyester fiber felt layer 51 of the first composite insulation layer 41 abuts against the connecting profile 23; the flame-retardant non-woven fabric layer 53 and the polyester fiber felt layer 51 of the second composite insulation layer 42 abut against the two intermediate connecting plates 13 respectively.
[0036] Both the first composite insulation layer 41 and the second composite insulation layer 42 adopt a three-layer structure, consisting of a polyester fiber felt layer 51, a polyurethane foam layer 52, and a flame-retardant non-woven fabric layer 53 stacked in sequence, thereby achieving good insulation, flame retardancy, and structural adaptability.
[0037] Specifically, the flame-retardant non-woven fabric layer 53 of the first composite insulation layer 41 is located near the outer edge of the window sash and directly abuts against the first sealing body 24. This fabric layer not only provides good flame-retardant protection but also maintains interface stability during contact with the first sealing body 24, preventing sealing failure due to thermal expansion and contraction or pressure changes. The polyester fiber felt layer 51 is located near the inside of the window sash and abuts against the connecting profile 23. Its good flexibility and resilience can compensate for structural deviations between the window sash frame and play a certain role in filling gaps and buffering, improving the tightness of the connection area. The polyurethane foam layer 52 is located in the middle and serves as the main insulation carrier material layer. It has an extremely low thermal conductivity and excellent closed-cell structure, which can effectively suppress heat conduction and convection. The same applies to the polyester fiber felt layer 51, polyurethane foam layer 52, and flame-retardant non-woven fabric layer 53 of the second composite insulation layer 42. Without significantly increasing the overall weight of the doors and windows, the thermal insulation capacity of the doors and windows is greatly improved.
[0038] In one example, the first sealing body 24 is provided with a plurality of first sealing chambers 24a. The first sealing chambers 24a can be evenly distributed along the length direction of the first sealing body 24 and form a closed or semi-closed cavity structure. The sealing chambers 24a provide good deformation buffering capacity and flexible support performance for the first sealing body 24 without destroying its outer contour, so as to ensure the sealing performance and service life of the first sealing body 24.
[0039] In one example, the second sealing body 14 includes an integrally connected base area 6 and a contact area 7. The base area 6 is connected to the intermediate connecting plate 13, and the contact area 7 is located at the front end of the base area 6. After the movable window sash 2 is closed relative to the composite window frame 1, the contact area 7 abuts against the first sealing body 24.
[0040] Therefore, the contact area 7 is located at the free end of the base area 6, and its cross-sectional structure can be a convex or arc-shaped structure, which is used to effectively fit and press against the first sealing body 24 on it when the movable window sash 2 is closed, thereby forming a reliable sealing interface.
[0041] Among them, a number of second sealing chambers 14a for deformation buffering are provided between the contact area 7 and the base area 6. The second sealing chambers 14a are closed or semi-closed structures and are arranged at intervals along the length of the second sealing body 14. When under pressure, the second sealing chambers 14a can generate controllable elastic deformation, effectively absorbing the compressive stress generated when the window sash is closed, and at the same time enhancing the resilience of the contact area 7, thereby improving the long-term stability and fatigue resistance of the sealing system.
[0042] Optionally, to further improve the connection strength and assembly convenience between the second sealing body 14 and the intermediate connecting plate 13, the base area 6 is integrally connected with the mounting body 61. The mounting bodies 61 are arranged at intervals on the side of the base area 6 facing the intermediate connecting plate 13, thereby ensuring that the base area 6 is stably connected to the intermediate connecting plate 13 at multiple points through the mounting bodies 61.
[0043] Specifically, the mounting body 61 includes a snap-fit part 611 and a connecting part 612. The connecting part 612 connects the snap-fit part 611 and the base area 6 respectively, providing sufficient structural ductility and stress buffering without affecting the sealing performance. The intermediate connecting plate 13 has a mounting groove 131 on the side facing the base area 6. The mounting groove 131 corresponds to the mounting body 61. The snap-fit part 611 snaps into the mounting groove 131. The snap-fit part 611 gradually tapers from the base area 6 towards the intermediate connecting plate 13, that is, the snap-fit part 611 has a wedge-shaped or inverted cone-shaped structure. The tapering structure design of the snap-fit part 611 ensures that its external dimensions closely match the cross-sectional shape of the mounting groove 131. When the snap-fit part 611 is inserted, it can be easily aligned and guided into the mounting groove 131. After being snapped in, it forms a self-locking fit, which has good anti-dislodgement ability. It also facilitates the rapid batch installation of multi-section sealing bodies and improves production assembly efficiency.
[0044] In the specific implementation process, the side of the contact area 7 away from the base area 6 is integrally connected with a first sealing claw 71 and multiple second sealing claws 72. The first sealing claw 71 and the second sealing claw 72 are evenly arranged on the contact area 7. After the movable window sash 2 is closed relative to the composite window frame 1, the ends of the first sealing claw 71 and the second sealing claw 72 away from the contact area 7 are interference-connected with the first sealing body 24 to jointly form a multi-seal structure, providing a stepped multi-point contact sealing effect during the closing of the door and window.
[0045] Specifically, both the first sealing claw 71 and the second sealing claw 72 extend toward the first sealing body 24, that is, toward the movable window sash 2. Their free ends (i.e. the ends away from the contact area 7) form an interference fit with the first sealing body 24 when the door and window are closed, so that each sealing claw can generate a continuous pressing force when closed, thereby ensuring that the contact area has a good sealing and pressing effect at different stress points, effectively preventing air, water vapor or dust from penetrating.
[0046] In terms of structural design, the first sealing claw 71 is preferably located in the main force-bearing area of the contact area 7. Its size and shape are relatively large, and it has a strong clamping ability.
[0047] Furthermore, the line connecting the ends of the multiple second sealing claws 72 away from the contact area 7 matches the outer wall contour of the first sealing body 24. The coordinated distribution and shape of the first sealing claw 71 and the second sealing claw 72 make the entire contact area 7 form a multi-level sealing structure combining main and auxiliary functions, effectively adapting to the minute deformation and assembly tolerances during the closing process of doors and windows.
[0048] The arrangement of multiple second sealing claws 72 in height and direction forms a sealing contact curve. This curve fits spatially with the outer wall surface of the first sealing body 24, ensuring that the second sealing claws 72 form a uniform and stable multi-point contact with the first sealing body 24 when the door or window is closed. Through this curve matching arrangement, the second sealing claws 72 can be set with different heights or inclinations at different positions according to the shape characteristics of the first sealing body 24, thereby achieving synchronous pressing, no obvious stress concentration, and no obvious joint fluctuation during the closing process.
[0049] It should be noted that the first frame 21 and the second frame 22 are each provided with a first snap-fit groove 201 on their facing sides, and the first sealing body 24 is provided with first snap-fit blocks 202 at both ends. The first snap-fit blocks 202 are matched in the first snap-fit grooves 201. Similarly, the first profile 11 and the second profile 12 are each provided with a second snap-fit groove 101 on their facing sides, and the two intermediate connecting plates 13 are each provided with a second snap-fit block 102 at both ends. The second snap-fit blocks 202 are matched in the second snap-fit grooves 101. The first snap-fit blocks 202 and the second snap-fit blocks 202... Block 102 is preferably designed as a U-shaped or dovetail-shaped structure, which has good limiting and locking functions, and facilitates stable assembly of components. The outer shape of the first snap-fit block 202 matches the outer shape of the first snap-fit groove 201, and the outer shape of the second snap-fit block 102 matches the outer shape of the second snap-fit groove 101, which is used to realize the embedded connection in the structure. In the specific installation process, the first snap-fit block 202 can be assembled into the first snap-fit groove 201 by insertion, pressing or slight snap-locking to form a stable mechanical fixing relationship, thereby forming a frame-type edge-wrapping structure.
[0050] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
