Description

Technical Field

[0001] This invention relates to the field of aluminum alloy door and window technology, and specifically to an aluminum alloy door and window installation and sealing assembly. Background Technology

[0002] Aluminum alloy doors and windows, with their comprehensive advantages of being lightweight, high-strength, corrosion-resistant, aesthetically pleasing, and durable, have become one of the most widely used types of doors and windows in modern buildings. Among the many opening methods of aluminum alloy doors and windows, sliding aluminum alloy windows are one of the most common choices for homes and offices due to their space-saving opening, wide field of vision, and ease of operation.

[0003] However, because sliding windows open and close by sliding horizontally along a track on the window frame, their structural characteristics dictate that there will inevitably be multiple gaps between the window sash and the window frame. These gaps primarily include the horizontal gaps between the upper and lower horizontal members of the window sash and the upper and lower sliding tracks of the window frame, the vertical gaps between the left and right side rails of the window sash and the window frame edges, and the vertical gaps at the interlocking points of the two window sashes. These gaps are the main channels for indoor and outdoor air convection, dust infiltration, rainwater leakage, and noise transmission. Therefore, it is necessary to install weatherstripping or sealing strips in the corresponding areas, using sealing materials to fill the gaps between the frame and the sash to ensure the airtightness, watertightness, and sound insulation performance of the doors and windows.

[0004] For example, Chinese patent CN202359964U discloses a sliding door and window with good sealing performance. It uses weatherstripping installed on the inner walls of the sliding groove at the bottom of the window sash to form a clamp-on sealing structure with the side of the sliding rail of the window frame. However, in this design, the weatherstripping is installed on the inner walls of the sliding groove on both sides of the window sash, with the weatherstripping pointing horizontally towards the middle of the sliding rail. With long-term use, as the window sash is repeatedly pushed and pulled, dust accumulated in the sliding groove of the window frame easily enters the roots of the weatherstripping: on the one hand, the dust accumulated in the track is dispersed by the push of the window sash end, infiltrating between the weatherstripping; on the other hand, dust adhering to the surface of the sliding rail seeps into the gaps between the weatherstripping and the side of the guide rail. Because the weatherstripping points horizontally towards the guide rail and lacks a dust-guiding structure, once dust enters the gaps between the weatherstripping, it is repeatedly squeezed and pushed horizontally by the obstruction of the sliding rail, gradually migrating and accumulating towards the roots of the weatherstripping. This eventually leads to the weatherstripping bending, loss of elasticity, increased pushing and pulling resistance, and accelerated deterioration of the sealing performance.

[0005] To address the aforementioned problems, this invention proposes an aluminum alloy door and window installation sealing assembly. Summary of the Invention

[0006] (1) Technical problems to be solved The purpose of this invention is to overcome the problem of dust intrusion into the root of the hair fibers in the prior art, which leads to sealing failure, and to meet practical needs by providing an aluminum alloy door and window installation sealing component to solve the above-mentioned technical problems.

[0007] (2) Technical solution To achieve the objectives of this invention, the technical solution adopted is as follows: An aluminum alloy door and window installation sealing assembly for installation on a sliding window sash includes: a weatherstrip assembly disposed on the inner wall of the bottom slide groove of the window sash; the weatherstrip assembly includes: a base disposed on the inner wall of the bottom slide groove; a mounting wall disposed on the side of the base facing the bottom slide rail of the window frame; and a bristle array disposed on the mounting wall, the bristle array being composed of multiple bristles, each bristle having a root and a free end, the root being fixedly connected to the mounting wall, and the free end abutting against the side wall of the bottom slide rail; wherein the root extends obliquely towards the free end, and the root is higher than the free end in the vertical direction.

[0008] Furthermore, the filaments are configured to have antistatic properties, with an antistatic coating on their surface and / or containing conductive fibers inside.

[0009] Furthermore, a slot is provided on the side wall of the bottom slide groove. The slot is surrounded by a first support arm and a second support arm arranged opposite to each other. The base is inserted into the slot, and the height of the base is adapted to the height of the slot. Two first stop blocks are provided on the upper side of the base, and the two first stop blocks are respectively located on both sides of the thickness direction of the first support arm. Two second stop blocks are provided on the lower side of the base, and the two second stop blocks are respectively located on both sides of the thickness direction of the second support arm.

[0010] Furthermore, the two first stop blocks abut against the two sides of the first support arm in the thickness direction, and the two second stop blocks abut against the two sides of the second support arm in the thickness direction, so as to restrict the base from moving in the slot and keep the free end of the hair abutting against the side wall of the bottom slide rail.

[0011] Furthermore, the minimum distance between the two first stop blocks is greater than the thickness of the first support arm, and the minimum distance between the two second stop blocks is greater than the thickness of the second support arm, so that the base can move in the thickness direction within the slot; the sliver assembly has a first position and a second position, wherein: in the first position, the first stop block and the second stop block away from the bottom slide rail abut against the first support arm and the second support arm respectively, and the free end of the sliver abuts against the side wall of the bottom slide rail; in the second position, the first stop block and the second stop block close to the bottom slide rail abut against the first support arm and the second support arm respectively, and the free end of the sliver abuts against the side wall of the bottom slide rail; a receiving cavity is provided in the bottom slide groove away from the sliver assembly, and a movable part that can move along the width direction of the bottom slide groove is provided in the receiving cavity, and the movable part is connected to the sliver assembly to drive the sliver assembly to switch between the first position and the second position.

[0012] Furthermore, the movable part includes a movable plate, a connecting strip is fixedly connected to the side of the movable plate near the weatherstripping assembly, a connecting groove is provided through the base along the length direction, the connecting groove is adapted to the connecting strip; the connecting groove has a connecting section extending along the thickness direction of the base, and at least one limiting section communicating with the inner end of the connecting section and extending at an angle to the connecting section.

[0013] Furthermore, the sealing assembly also includes at least one spring disposed within the receiving cavity, one end of which is fixedly connected to the inner wall of the receiving cavity, and the other end of which is fixedly connected to the movable plate. The spring provides a driving force to the hairline assembly to drive it to move from the first position to the second position.

[0014] Furthermore, the sealing assembly also includes a self-locking drive unit, which is used to move the felt assembly from the second position to the first position and lock it in the first position.

[0015] Furthermore, the self-locking drive unit includes a boss and a transmission member. The boss is fixedly connected to the side of the movable plate away from the napper assembly. The boss has a position holding surface and inclined walls disposed on both sides of the position holding surface. The inclined walls extend inclinedly from the position holding surface to the movable plate along the length direction. The transmission member includes a connecting arm and a transmission arm disposed at one end of the connecting arm. The transmission arm has a locked position and a free position, wherein: when the transmission arm is in the locked position, the transmission arm abuts against the position holding surface, and the napper assembly is in the first position; when the transmission arm is in the free position, the transmission arm is misaligned with the boss, and the spring drives the napper assembly to move from the first position to the second position, and during the movement, reciprocating vibration is generated to shake off the dust from the free end of the napper, and finally stops at the second position.

[0016] Furthermore, the sealing assembly also includes a drive assembly for installation in a groove on the window sash. The drive assembly includes a handle body, the bottom of which is fixedly connected to a first transmission rod. The first transmission rod is fixedly connected to a connecting arm and is configured to move in a preset channel within the window sash. It also includes two damping resetters, which are respectively connected between the two sides of the handle body and the corresponding inner walls of the groove. Beneficial effects

[0017] In this invention, by extending the root of the bristles at an angle towards the free end, with the root higher than the free end, dust naturally slides along the bristle surface towards the free end under gravity. Simultaneously, the bristle surface is coated with an antistatic coating and / or contains conductive fibers, effectively reducing dust adhesion. During the window sash sliding process, a spring drives the bristle assembly to move from a first position to a second position, releasing the bottom rail from obstructing dust at the free end, and generating reciprocating vibration during movement, further shaking off the dust accumulated at the free end of the bristles. By utilizing the synergy of inclined guidance, antistatic properties, and vibration, the problem of dust intrusion into the bristle root leading to seal failure in existing technologies is solved, significantly extending the effective sealing of the bristle assembly.

[0018] In this invention, by setting a slot, a first support arm, a second support arm, a first stop block, and a second stop block, and controlling the relationship between the spacing of the first and second stop blocks and the thickness of the first and second support arms, the base can move along the thickness direction within the slot. Combined with the movable part, spring, and self-locking drive part, the weatherstripping assembly can switch between a first position and a second position: when sealing, the free ends of the weatherstripping are tightly against the side wall of the bottom slide rail; when pushing or pulling, the weatherstripping assembly automatically moves away from the bottom slide rail. This ensures that the weatherstripping completely disengages from the bottom slide rail during window opening, resulting in almost zero pushing and pulling resistance, while also overcoming the wear caused by continuous friction of the weatherstripping in existing technologies.

[0019] In this invention, the drive assembly adopts a structure of handle body and first transmission rod. When the user moves the window sash by pushing or pulling the handle, the weatherstrip assembly can be dynamically disengaged. After the handle body is released, the damping reset device drives the handle body to reset. With the cooperation of the self-locking drive unit, the sealing state of the weatherstrip assembly is automatically restored. No complicated operation is required, which is suitable for daily use.

Detailed Implementation

[0022] In the prior art, aluminum alloy doors and windows include a window frame 3 installed in a pre-set wall opening, and two sliding window sashes 1 are provided inside the window frame 3, with glass installed on each sash. A bottom slide rail 31 and a top slide rail 32 are respectively provided at the bottom and top of the window frame 3, and a bottom slide groove 11 and a top slide groove 15 are respectively provided at the bottom and top of the window sashes 1. The sliding of the window sashes 1 on the window frame 3 is achieved by the bottom slide groove 11 cooperating with the bottom slide rail 31 and the top slide groove 15 cooperating with the top slide rail 32.

[0023] To ensure the airtightness and watertightness of doors and windows, it is usually necessary to add seals at multiple moving gaps between the window sash 1 and the window frame 3. For example, Chinese patent CN202359964U discloses a sliding door and window with good sealing performance, which adds weatherstripping at multiple moving gaps. However, for the weatherstripping that is set on the inner walls of both sides of the bottom sliding groove 11 of the window sash 1 and forms a clamping seal with the two sides of the guide rail, since it is horizontally oriented towards the guide rail, dust can easily penetrate into the roots of the hairs and accumulate after long-term use, eventually leading to the hairs bending, loss of elasticity, increased sliding resistance, and accelerated deterioration of sealing performance.

[0024] Therefore, the present invention provides an aluminum alloy door and window installation sealing assembly. The following is in conjunction with the attached... Figure 1-7 The present invention will be described in detail with reference to the embodiments.

[0025] like Figures 1-9As shown, an aluminum alloy door and window installation sealing assembly is installed on the window sash 1 of a sliding window to achieve a seal between the bottom slide groove 11 of the window sash 1 and the bottom slide rail 31 of the window frame 3. The assembly includes: a weatherstripping assembly 2, disposed on the inner wall of the bottom slide groove 11 of the window sash 1; the weatherstripping assembly 2 includes: a base 21, disposed on the inner wall of the bottom slide groove 11; a mounting wall 22, disposed on the side of the base 21 facing the bottom slide rail 31 of the window frame 3; and a bristle array 23, disposed on the mounting wall 22. The bristle array 23 is composed of multiple bristles 231, and each bristle 231 has a root 2311 and a free end 2312. The root 2311 is fixedly connected to the mounting wall 22, and the free end 2312 abuts against the side wall of the bottom slide rail 31. The root 2311 extends obliquely towards the free end 2312, and the root 2311 is higher than the free end 2312 in the vertical direction.

[0026] Specifically, by making the root 2311 of the bristles 231 extend obliquely towards the free end 2312, and the root 2311 is higher than the free end 2312 in the vertical direction, when dust enters the gap of the bristles 231, it will naturally slide along the surface of the bristles 231 towards the free end 2312 under the action of gravity, thus preventing dust from accumulating at the root 2311. This effectively delays the collapse and loss of elasticity of the bristles 231 caused by dust accumulation at the root 2311, and significantly extends the effective service life of the sealing assembly.

[0027] Preferably, the mounting wall 22 is inclined, and the bristles 231 are perpendicular to the mounting wall 22.

[0028] The filament 231 is configured to have antistatic properties, with an antistatic coating on its surface and / or containing conductive fibers inside.

[0029] Specifically, the surface of the filament 231 is provided with an antistatic coating and / or contains conductive fibers, which can significantly reduce the accumulation of static charge on the surface of the filament 231, thereby reducing the electrostatic attraction between dust and the filament 231, reducing the resistance to the movement of dust along the surface of the filament 231 to the free end 2312, making it easier for dust to move to the free end 2312 under the action of gravity, and also creating favorable conditions for the dust to detach smoothly from the filament 231 at the free end 2312.

[0030] A slot 111 is provided on the side wall of the bottom slide groove 11. The slot 111 is surrounded by a first support arm 112 and a second support arm 113 arranged opposite to each other. The base 21 is inserted into the slot 111, and the height of the base 21 is adapted to the height of the slot 111. Two first stop blocks 24 are provided on the upper side of the base 21, and the two first stop blocks 24 are respectively located on both sides of the thickness direction of the first support arm 112. Two second stop blocks 25 are provided on the lower side of the base 21, and the two second stop blocks 25 are respectively located on both sides of the thickness direction of the second support arm 113.

[0031] Specifically, by opening a slot 111 formed by the first support arm 112 and the second support arm 113 on the side wall of the bottom slide groove 11, and inserting the base 21 into the slot 111, and cooperating with the two first stop blocks 24 and the two second stop blocks 25 located on the upper and lower sides respectively in the thickness direction, the base 21 can be quickly positioned and installed, and the structure is compact.

[0032] Example 1: In this example, two first stop blocks 24 abut against the two sides of the first support arm 112 in the thickness direction, and two second stop blocks 25 abut against the two sides of the second support arm 113 in the thickness direction, so as to restrict the base 21 from moving in the slot 111, and keep the free end 2312 of the filament 231 abutting against the side wall of the bottom slide rail 31.

[0033] Specifically, the two first stop blocks 24 abut against the two sides of the first support arm 112 in the thickness direction, and the two second stop blocks 25 abut against the two sides of the second support arm 113 in the thickness direction, thereby firmly restricting the base 21 in the slot 111, preventing it from moving along the thickness direction, and ensuring that the free end 2312 of the filament 231 always remains stably abutted against the side wall of the bottom slide rail 31, thereby achieving a reliable static seal.

[0034] In this embodiment, the base 21 is restricted and cannot move along the thickness direction of the bottom slide groove 11. The free end 2312 of the bristles 231 always remains against the side wall of the slide rail, achieving a static seal. At this time, when the window sash 1 is pushed or pulled, the sliding friction between the free end 2312 of the bristles 231 and the bottom slide rail 31 will generate micro-vibrations, which helps to shake off the dust accumulated at the free end 2312 and discharge it from the gaps between the bristles 231.

[0035] It should be noted that, in this embodiment, in order to prevent the base 21 from shifting along the length direction within the slot 111, the base 21 can be locked to the first support arm 112 or the second support arm 113 by conventional methods such as set screws, which will not be described in detail here.

[0036] Example 2: As another implementation method, unlike Example 1, the base 21 can move along the thickness direction within the slot 111, and is equipped with a movable part 4, a receiving cavity 12, a spring 5, a self-locking drive part 6, and a drive assembly 7, etc., to achieve dynamic disengagement and repositioning of the brush assembly 2. Details are as follows: The minimum distance between the two first stop blocks 24 is greater than the thickness of the first support arm 112, and the minimum distance between the two second stop blocks 25 is greater than the thickness of the second support arm 113, so that the base 21 can move in the thickness direction within the slot 111; the bristle assembly 2 has a first position and a second position, wherein: in the first position, the first stop blocks 24 and the second stop blocks 25, which are away from the bottom slide rail 31, abut against the first support arm 112 and the second support arm 113 respectively, and the free end 2312 of the bristle 231 abuts against the bottom. The side wall of the slide rail 31; in the second position, the first stop block 24 and the second stop block 25 near the bottom slide rail 31 abut against the first support arm 112 and the second support arm 113 respectively, and the free end 2312 of the hair 231 is away from the side wall of the bottom slide rail 31; a receiving cavity 12 is provided in the bottom slide groove 11 at a position away from the hair sliver assembly 2, and a movable part 4 that can move along the width direction of the bottom slide groove 11 is provided in the receiving cavity 12. The movable part 4 is connected to the hair sliver assembly 2 to drive the hair sliver assembly 2 to switch between the first position and the second position.

[0037] Specifically, by setting the minimum distance between the first stop blocks 24 to be greater than the thickness of the corresponding first support arm 112, and the minimum distance between the second stop blocks 25 to be greater than the thickness of the corresponding second support arm 113, the base 21 can move along the thickness direction within the slot 111, thereby assigning the weatherstrip assembly 2 a first position (sealed position) and a second position (disengaged position). Simultaneously, a movable part 4 that can move along the width direction of the bottom slide groove 11 is provided, driving the weatherstrip assembly 2 to switch between the two positions. When the window sash 1 is pushed or pulled, the movable part 4 drives the weatherstrip assembly 2 to move to the second position, and the free end 2312 of the bristles 231 actively moves away from the bottom slide rail 31. On the one hand, this removes the obstruction of dust at the free end 2312 by the bottom slide rail 31, allowing dust to easily detach from the free end 2312, achieving self-cleaning; on the other hand, it eliminates the frictional contact between the bristles 231 and the slide rail, significantly reducing the pushing and pulling resistance. When the window sash 1 is stationary, the weatherstripping assembly 2 returns to its first position, and the free end 2312 of the weatherstripping filaments 231 abuts against the side wall of the slide rail again, restoring a reliable seal. This achieves both low pushing and pulling resistance and high static sealing performance, while also providing dust removal functionality.

[0038] It should be noted that, in this embodiment, in order to prevent the base 21 from shifting along the length direction within the slot 111, the base 21 can be locked to the movable part 4 by conventional methods such as set screws, which will not be described in detail here.

[0039] The movable part 4 includes a movable plate 41, on the side of the movable plate 41 near the weatherstripping assembly 2, a connecting strip 42 is fixedly connected, and a connecting groove 211 is provided through the base 21 along the length direction. The connecting groove 211 is adapted to the connecting strip 42. The connecting groove 211 has a connecting section 2111 extending along the thickness direction of the base 21, and at least one limiting section 2112 communicating with the inner end of the connecting section 2111 and extending at an angle to the connecting section 2111.

[0040] Specifically, by fixing a connecting strip 42 to the side of the movable plate 41 near the strip assembly 2 and providing a connecting groove 211 through the base 21 along the length direction, the connecting groove 211 can be simultaneously fitted onto the connecting strip 42 during the process of inserting the base 21 into the slot 111 along the length direction, thus realizing convenient assembly of the movable plate 41 and the base 21.

[0041] The cavity 12 is provided with multiple guide rods 8, and the movable plate 41 is slidably connected to the guide rods 8 to prevent them from shifting or getting stuck.

[0042] It should be noted that the connecting groove 211 extends through the base 21 along its length. In cross-section, the connecting groove 211 has a connecting section 2111 extending along the thickness of the base 21, and a limiting section 2112 communicating with the inner end of the connecting section 2111 and extending at an angle to it. When the base 21 is inserted into the slot 111 along its length, the neck of the connecting bar 42 slides within the connecting section 2111, and the head of the connecting bar 42 slides within the limiting section 2112, thereby preventing the connecting bar 42 from coming out.

[0043] The sealing assembly also includes at least one spring 5, which is disposed in the receiving cavity 12. One end of the spring 5 is fixedly connected to the inner wall of the receiving cavity 12, and the other end is fixedly connected to the movable plate 41. The spring 5 provides a driving force to the hairline assembly 2 to drive it to move from the first position to the second position.

[0044] Specifically, by setting a spring 5 inside the accommodating cavity 12, with one end fixed to the inner wall of the accommodating cavity 12 and the other end fixed to the movable plate 41, the spring 5 provides a driving force to the weatherstrip assembly 2 to move from the first position to the second position, thereby realizing the automatic disengagement of the weatherstrip assembly 2 when pushing and pulling the window sash 1 without the need for additional operation by the user. The structure is simple and the response is rapid.

[0045] The sealing assembly also includes a self-locking drive unit 6, which is used to move the felt assembly 2 from the second position to the first position and lock it in the first position.

[0046] Specifically, a self-locking drive unit 6 is added to move the weatherstrip assembly 2 from the second position back to the first position and lock it, ensuring that the weatherstrip assembly 2 can reliably restore the sealing state when the window sash 1 is closed or stationary, avoiding accidental disengagement caused by spring force or external vibration, and enhancing the static stability of the sealing assembly.

[0047] The self-locking drive unit 6 includes a boss 61 and a transmission member 62. The boss 61 is fixedly connected to the side of the movable plate 41 away from the napper assembly 2. The boss 61 has a position holding surface 611 and inclined walls 612 provided on both sides of the position holding surface 611. The inclined walls 612 extend inclinedly from the position holding surface 611 toward the movable plate 41 along the length direction. The transmission member 62 includes a connecting arm 621 and a transmission arm 622 provided at one end of the connecting arm 621. The transmission arm 622 has a locked position and a free position. When the transmission arm 622 is in the locked position, the transmission arm 622 abuts against the position holding surface 611, and the napper assembly 2 is in the first position. When the transmission arm 622 is in the free position, the transmission arm 622 is misaligned with the boss 61. The spring 5 drives the napper assembly 2 to move from the first position to the second position, and during the movement, it generates reciprocating vibration to shake off the dust from the free end 2312 of the napper 231, and finally stops at the second position.

[0048] Specifically, through the cooperation of the position holding surface 611 on the boss 61 and the connecting arm 621 and the transmission arm 622 on the transmission member 62, when the transmission arm 622 is in the locked position, it abuts against the position holding surface 611 to lock the hairline assembly 2 in the first position; when the transmission arm 622 is in the free position, it is misaligned with the boss 61, and the spring 5 drives the hairline assembly 2 to move to the second position and generate reciprocating vibration. This vibration can effectively shake off the dust accumulated on the free end 2312 of the hairline 231, achieving dynamic disengagement while also having a self-cleaning function, further extending the maintenance cycle of the sealing assembly. By setting the inclined wall 612, when the transmission arm 622 resets from the free position to the locked position, the transmission arm 622 slides along the inclined wall 612, and the guide action of the inclined wall 612 pushes the boss 61 and the movable plate 41 to move, thereby driving the base 21 and the hairline assembly 2 from the second position back to the first position, and finally the transmission arm 622 abuts against the position holding surface 611 to achieve locking. The reset process requires no additional driving components, has a simple structure, and is reliable in operation, further extending the maintenance cycle of the sealing assembly.

[0049] The sealing assembly also includes a drive assembly 7 for installation in a groove 13 on the window sash 1. The drive assembly 7 includes a handle body 71, with a first transmission rod 72 fixedly connected to the bottom of the handle body 71. The first transmission rod 72 is fixedly connected to the connecting arm 621 and is configured to move in a preset channel 14 within the window sash 1. It also includes two damping resetters 73, which are respectively connected between the two sides of the handle body 71 and the corresponding inner walls of the groove 13.

[0050] Specifically, the drive assembly 7 is configured to include a handle body 71, a first transmission rod 72, and a damping reset device 73. One end of the first transmission rod 72 is fixedly connected to the bottom of the handle body 71, and the other end is fixedly connected to the connecting arm 621 of the self-locking drive unit 6. The first transmission rod 72 is configured to move within the preset channel 14 of the window sash 1. When the window sash 1 needs to be pushed or pulled, the user first pulls the handle body 71. The first transmission rod 72 drives the connecting arm 621 to switch the transmission arm 622 from the locked position to the free position. The spring 5 then drives the weatherstrip assembly 2 to move from the first position to the second position. The free end 2312 of the weatherstrip 231 moves away from the bottom slide rail 31, allowing the user to push or pull the window sash 1 smoothly with minimal resistance. During this movement, the bottom slide rail 31 removes the obstruction of dust at the free end 2312, and the weatherstrip assembly 2 vibrates reciprocally, shaking off the dust accumulated at the free end 2312 of the weatherstrip 231. After pushing or pulling, the user releases the handle body 71. Two damping reset devices 73 are respectively connected between the two sides of the handle body 71 and the corresponding inner wall of the groove 13, so that the handle is slowly and smoothly reset. At the same time, the transmission arm 622 returns to the locked position, and the bristles 231 of the weatherstrip assembly 2 abut against the bottom slide rail 31 again, restoring the static seal. It links the dynamic disengagement of the sealing assembly with the pushing and pulling action of the window sash 1. The user only needs to pull the handle once to complete the unlocking and pushing and pulling preparation, which is simple to operate.

[0051] It should be noted that the sealing structure at the top slide groove 15 can refer to the design of the bottom weatherstripping assembly 2, but it needs to be adapted to the fitting requirements of the top slide rail 32. Specifically, the top slide groove 15 is also equipped with a top weatherstripping assembly, the structure of which, including the base, mounting wall, hair array, moving part, spring, and self-locking drive part, is the same as that of the bottom weatherstripping assembly 2. The difference is that the hairs of the top weatherstripping are horizontally pointing towards the side wall of the top slide rail 32 to achieve a reliable static seal.

[0052] To simultaneously release the contact between the top weatherstripping and the top slide rail 32 when the window sash 1 is pushed or pulled, the drive assembly 7 may be further provided with a second transmission rod. The upper end of the second transmission rod is connected to the transmission component of the self-locking drive part of the top weatherstripping assembly, and the lower end is connected to the handle body 71. When the user pulls the handle body 71, the second transmission rod drives the top transmission arm to switch from the locked position to the free position, and the top spring drives the top weatherstripping assembly to move away from the top slide rail 32, achieving synchronous disengagement.

[0053] Furthermore, since the pushing and pulling action of the window sash 1 includes two opposite directions—pushing forward and pulling backward—the movement direction of the handle body 71 is also opposite. Therefore, the transmission arm 622 of the self-locking drive unit 6 has two free positions, located on either side of the boss 61, to accommodate both pushing forward and pulling backward working conditions of the handle body 71, ensuring that the dynamic disengagement of the weatherstripping assembly 2 is triggered regardless of which direction the window sash 1 moves.

[0054] Preferably, the damping resetter 73 is a miniature telescopic resetter integrating disc spring and damping functions, hereinafter referred to as the "disc spring damping resetter," which internally contains a pre-compressed disc spring assembly and a damping medium. Two disc spring damping resetters are respectively connected between the two sides of the handle body 71 and the corresponding inner walls of the groove 13: their housing ends are fixed to the side walls of the groove 13, and their telescopic rod ends are fixedly connected to the side of the handle body 71. When the user pulls the handle body 71, the disc spring damping resetter is compressed, and the pre-compressed disc spring inside stores elastic potential energy. Simultaneously, the damping medium generates viscous resistance through the built-in damping hole, making the compression process smooth and controllable. When the user releases the handle body 71, the pre-compressed disc spring releases energy to drive the telescopic rod to extend, and the damping medium again generates reverse damping through the damping hole, causing the handle body 71 to slowly and smoothly reset to its initial position, avoiding impact and noise. The specific structure of the disc spring damping resetter can adopt the integrated structure of a miniature hydraulic damper and a disc spring in the prior art, which can be implemented by those skilled in the art based on the description in this specification.

[0055] Working principle: The usage method of this aluminum alloy door and window sealing component is as follows: During installation, first ensure that the transmission arm 622 of the self-locking drive unit 6 is in the locked position, i.e., abutting against the position holding surface 611 of the boss 61. Then, insert the base 21 along its length into the slot 111 at the bottom of the window sash 1. During insertion, the connecting groove 211 on the base 21 simultaneously engages with the connecting strip 42 on the movable plate 41, connecting the movable part 4 to the base 21. Continue pushing the base 21 to the predetermined depth. Since the transmission arm 622 is in the locked position, the weatherstrip assembly 2 is locked in the first position. At this time, the free end 2312 of the bristles 231 tightly abuts against the side wall of the bottom slide rail 31, forming a static seal. Simultaneously, two damping reset devices 73 are respectively connected between the two sides of the handle body 71 and the inner wall of the groove 13, bringing the drive assembly 7 to the initial equilibrium position.

[0056] When the window sash 1 needs to be pushed or pulled, the user first pulls the handle body 71. The handle body 71 moves along the groove 13, overcoming the damping force of the damping reset device 73, and at the same time driving the first transmission rod 72 to move along the channel 14. The first transmission rod 72 pulls the connecting arm 621, causing the transmission arm 622 to disengage from the locked position and switch to the free position, that is, to be misaligned with the boss 61. At this time, the self-locking drive part 6 releases the lock on the weatherstrip assembly 2, and the driving force of the spring 5 is released.

[0057] Spring 5 pushes movable plate 41 and base 21 to move away from bottom slide rail 31. Due to the gaps between the first stop block 24 and the first support arm 112, and between the second stop block 25 and the second support arm 113, base 21 can move smoothly in the thickness direction within slot 111, and the weatherstrip assembly 2 switches from the first position to the second position. During this movement, the free end 2312 of the bristles 231 separates from the side wall of bottom slide rail 31, and the positive pressure between the free end 2312 of the bristles 231 and bottom slide rail 31 immediately disappears, reducing pushing and pulling resistance. Users can push and pull the window sash 1 smoothly with very low resistance. At the same time, since the drive of spring 5 is a non-rigid impact, weatherstrip assembly 2 will generate small reciprocating vibrations, shaking off the dust accumulated at the free end 2312 of the bristles 231, achieving self-cleaning. The physical obstruction of dust by bottom slide rail 31 is also removed, and residual dust can be easily removed from bristles 231.

[0058] After the window sash 1 is pushed to the target position, the user releases the handle body 71. The handle body 71 slowly and smoothly returns to its initial position. When the handle body 71 returns to its initial position, the connecting arm 621 is pushed by the first transmission rod 72, causing the transmission arm 622 to return from the free position to the locked position. During the return process, the transmission arm 622 first contacts the inclined wall 612 of the boss 61, slides along the inclined wall 612, and pushes the boss 61 and the movable plate 41 to move through the guiding action of the inclined wall 612, thereby overcoming the driving force of the spring 5 and driving the base 21 and the weatherstrip assembly 2 to smoothly return from the second position to the first position. After the transmission arm 622 has completely passed the inclined wall 612, it abuts against the position holding surface 611, relocking the weatherstrip assembly 2 in the first position sealing position, and the free end 2312 of the bristles 231 again tightly abuts against the side wall of the bottom slide rail 31, restoring a reliable static seal.

[0059] When the user needs to push or pull the window sash 1 in the opposite direction, for example, changing from a pull window to a push window, since the transmission arm 622 of the self-locking drive unit 6 has two free positions, located on both sides of the boss 61, the transmission arm 622 can switch to the corresponding free position regardless of whether the handle body 71 is pushed forward or pulled backward, ensuring that the weatherstrip assembly 2 can reliably disengage and adapt to the bidirectional sliding requirements of the window sash 1.

[0060] While the bottom sealing assembly is working, the drive assembly 7 is also equipped with a second transmission rod. When the user pulls or releases the handle body 71, the second transmission rod moves, causing the top weatherstrip assembly to move away from the top slide rail 32 or reset, thus achieving synchronous dynamic disengagement and restoration of the top seal.
