[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0028] Please see Figures 3-6 This invention provides a technical solution: a waterproof sealing strip structure for window glass, including a waterproof strip 40. The waterproof strip 40 is used to abut against the window glass to achieve waterproof sealing. Specifically, the waterproof strip 40 includes a strip body 1 and an installation strip 2 integrally formed on the back of the strip body 1. The installation strip 2 is used to assist in the installation of the strip body 1. The surface of the strip body 1 is formed with a sealing strip 4; that is, the side of the strip body 1 that is in contact with the window glass is integrally injection molded with a sealing strip 4. The sealing strip 4 is abutted against and adhered to the window glass to achieve a waterproof seal for the window glass installation. A water-swellable component 5 is provided on the surface of the sealing strip body 1 below the sealing strip 4. The water-swellable component 5 is initially in the same state as the sealing strip 4, that is, the water-swellable component 5 also abuts against the window glass to achieve a seal for the window glass. This is the first sealing. When water leaks between the sealing strip 4 and the window glass, the water-swellable component 5 expands after encountering water to abut against and adhere to the window glass to achieve a second sealing. When the rubber strip body 1 experiences elastic fatigue or deformation, causing leakage between the sealing strip 4 and the water-swellable component 5 and the window glass, or when the sealing strip 4 deforms, resulting in leakage, rainwater passes through the sealing strip 4 and is absorbed by the water-swellable component 5. The water-swellable component 5 expands upon contact with water and then presses against the window glass again, thereby achieving a secondary seal on the window glass and significantly improving the sealing and waterproofing effect of the window glass waterproof sealing strip. Optionally, the water-swellable component 5 is a water-swellable micro-swellable rubber strip set on the surface of the rubber strip body 1. The water-swellable micro-swellable rubber strip is a rubber product strip made of water-soluble polymer material and rubber. It has the characteristics of general rubber products, but also has the function of self-expansion when it comes into contact with water.
[0029] This embodiment provides a waterproof sealing strip structure for window glass. A sealing strip 4 and a water-swellable component 5 are sequentially combined and arranged on the contact surface between the sealing strip body 1 and the window glass. The sealing strip 4 and the water-swellable component 5 abut against the window glass to achieve primary waterproofing. When the sealing strip body 1 experiences elastic fatigue, causing leakage between the sealing strip 4 and the water-swellable component 5 and the window glass, rainwater passes through the sealing strip 4 and is absorbed by the water-swellable component 5. The water-swellable component 5 expands upon contact with water and abuts against the window glass again, thus achieving a secondary seal for the window glass, blocking rainwater from entering and significantly improving the waterproof sealing effect. This also eliminates the problem of leakage due to elastic fatigue in current window glass waterproof sealing strips, making the waterproofing effect more reliable.
[0030] In another embodiment of the present invention, the water-swellable component 5 includes a strip-shaped rubber sleeve 51 integrally formed on the rubber strip body 1 and a core skeleton 52. The core skeleton 52 is embedded in the strip-shaped rubber sleeve 51. The strip-shaped rubber sleeve 51 is integrally injection molded on the side of the rubber strip body 1 that abuts against the window glass. A water-swellable rubber strip 53 is fixed on the surface of the core skeleton 52. The water-swellable rubber strip 53 is a rubber product strip made of water-soluble polymer material and rubber. It has the characteristics of general rubber products, but it also has the function of self-swelling when exposed to water. A guide strip 62 is provided at the top of the strip-shaped rubber sleeve 51. A guide hole 512 is opened at the bottom of the guide strip 62 and the guide hole 512 communicates with the inside of the strip-shaped rubber sleeve 51. A water-absorbing sponge layer 54 is provided on the outside of the water-swellable rubber strip 53. A strip frame 55 is provided in the strip-shaped rubber sleeve 51 along its length direction. The strip frame 55 is a rigid structure used to support the strip sleeve 51. It should be noted that when the rubber strip body 1 experiences elastic fatigue, causing leakage between the sealing strip 4 and the window glass, the leakage gap on the long strip sealing strip 4 is uneven. That is, when rainwater passes through the sealing strip 4, it cannot contact the water-swellable component 5 evenly. This causes the water-swellable component 5 to partially expand and press against the window glass during expansion and sealing (i.e., the water-swellable component 5 at the leaking position will continuously absorb water and expand). This creates a stepped gap between the expanded and unexpanded positions of the water-swellable component 5, causing rainwater to continue to leak from the stepped gap, thus affecting the sealing and waterproofing effect.
[0031] By configuring the water-swellable component 5 as a strip-shaped sleeve 51 integrally formed on the rubber strip body 1, and setting the water-swellable rubber strip 53, water-absorbing sponge layer 54, and strip frame 55 in the strip-shaped sleeve 51, and setting the top of the strip-shaped sleeve 51 with a guide band 62, and the bottom of the guide band 62 with a guide hole 512, which is connected to the inside of the strip-shaped sleeve 51, and the guide band 62 is attached to the surface of the window glass, when the rubber strip body 1 experiences elastic fatigue and leakage occurs between the sealing strip 4 set on it and the window glass, the rainwater is guided through the guide band 62 and finally enters the inside of the strip-shaped sleeve 51 through the guide hole 512. At this time, the rainwater is absorbed by the strip-shaped sleeve 51. The water-absorbing sponge layer 54 absorbs rainwater, and its water absorption efficiency is greater than that of the water-swellable rubber strip 53. This allows the water-absorbing sponge layer 54 to absorb the incoming rainwater and spread it quickly and evenly. Then, the water-swellable rubber strip 53 absorbs the rainwater in the water-absorbing sponge layer 54 and expands, causing the outer strip-shaped rubber sleeve 51 to expand, thereby sealing the window glass. At the same time, when the water-swellable rubber strip 53 expands and causes the strip-shaped rubber sleeve 51 to expand, it works in conjunction with the strip frame 55 to limit the expansion, making the expansion of the strip-shaped rubber sleeve 51 more even and comprehensive. This avoids uneven expansion caused by uneven water absorption of the water-swellable rubber strip 53, which could lead to contact gaps between it and the window glass, further improving the sealing effect.
[0032] In another embodiment of the present invention, the strip-shaped rubber sleeve 51 has an M-shaped cross-section and two inner cavities 511. Both inner cavities 511 are embedded with water-swellable rubber strips 53. The strip-shaped rubber sleeve 51 is provided with a connecting hole 513, which connects the two inner cavities 511 to achieve double water absorption and expansion sealing, thereby further improving the sealing effect.
[0033] In another embodiment of the present invention, a deformation compensation groove 61 is provided between the strip-shaped rubber sleeve 51 and the sealing strip 4. A connecting band 6 is formed on the top of the strip-shaped rubber sleeve 51, and the top of the connecting band 6 is connected to the sealing strip 4. A strip-shaped opening 21 is provided on the outer side of the mounting strip 2 along its length direction. The cross-section of the strip-shaped opening 21 is T-shaped, and a rigid support frame 22 is embedded in the strip-shaped opening 21. The cross-section of the rigid support frame 22 is T-shaped and matches the strip-shaped opening 21. The width of the rigid support frame 22 is greater than the width at the connection between the mounting strip 2 and the strip body 1. A plurality of brackets 521 are connected to one side of the core skeleton 52, and the brackets 521 penetrate through the strip body 1 and abut against the rigid support frame 22. It should be noted that both the sealing strip 4 and the water-swellable component 5 are formed on the strip body 1 and adhered to one side of the window glass. Initially, both the sealing strip 4 and the water-swellable component 5 are pressed against the window glass for sealing and waterproofing. When the strip body 1 or the sealing strip 4 experiences elastic fatigue or deformation, causing leakage between the sealing strip 4 and the window glass, rainwater passes through the sealing strip 4 and is absorbed by the water-swellable component 5. The water-swellable component 5 expands upon contact with water and presses against the window glass again, thus achieving a secondary seal for the window glass. However, when the water-swellable component 5 expands and deforms, its expansion deformation surface cannot guarantee that the gap between it and the window glass remains constant. That is, when the water-swellable component 5 expands and deforms against the glass, it generates a reverse force acting on the strip body 1, causing the strip body 1 to deform away from the window glass. This causes the strip body 1 to pull the sealing strip 4 away from the window glass, thus affecting the adhesion between the sealing strip 4 and the window glass.
[0034] By installing a water-swellable rubber strip 53 on the inner side of the strip sleeve 51 with a core skeleton 52, and embedding a rigid support frame 22 in the strip 2 with a strip opening 21, the core skeleton 52 passes through the strip body 1 through the bracket 521 and abuts against the rigid support frame 22. This allows the water-swellable rubber strip 53 to generate a reverse force when it expands and deforms against the glass. This reverse force is then abutted against the rigid support frame 22 by the core skeleton 52 and the bracket 521, thus preventing deformation caused by the action on the strip body 1. At the same time, the water-swellable rubber strip 53 abuts against the window glass during expansion and deformation, further improving the sealing effect. In addition, the width of the rigid support frame 22 is greater than the width of the connection between the strip 2 and the strip body 1. This allows the rigid support frame 22 to limit and fix the strip 2 after it is embedded in the installation groove, preventing it from falling out of the installation groove on the window frame 10, and improving the stability of the window glass waterproof sealing strip structure installation.
[0035] Furthermore, by providing a deformation compensation groove 61 between the strip-shaped rubber sleeve 51 and the sealing strip 4, and by forming a connecting band 6 on the top of the strip-shaped rubber sleeve 51, with the top of the connecting band 6 connected to the sealing strip 4, when the water-swelling rubber strip 53 expands and deforms, causing the outer strip-shaped rubber sleeve 51 to expand to seal the window glass, since the bottom of the connecting band 6 is connected to the strip-shaped rubber sleeve 51, when the strip-shaped rubber sleeve 51 expands and deforms, the connecting band 6 pulls the sealing strip 4, at which point the deformation compensation groove... The deformation compensation of the opening 61 allows the sealing strip 4 to press tightly against the window glass, thereby achieving sealing compensation for the sealing strip 4. When a gap occurs between the sealing strip 4 and the window glass and water leakage occurs, the water-expanding component 5 expands after encountering water and presses against the window glass again, thereby achieving secondary sealing of the window glass. At the same time, the connecting belt 6 pulls the sealing strip 4 to achieve sealing compensation for the sealing strip 4, so that the sealing strip 4 can press against the window glass again for waterproof sealing.
[0036] In another embodiment of the present invention, a water-drip strip 3 is formed on the upper side of the sealing strip 4 on the rubber strip body 1. Furthermore, by providing the water-drip strip 3 on the upper side of the sealing strip 4 on the rubber strip body 1, the water-drip strip 3 can directly guide a large amount of rainwater flowing down the window glass from the outside to the outside of the window, achieving preliminary drainage and waterproofing measures. Moreover, the water-expanding component 5 expands upon contact with water and then abuts against and adheres to the window glass again, thereby achieving a secondary seal for the window glass. Simultaneously, when the connecting strap 6 pulls and compensates for the sealing strip 4, it also causes the water-drip strip 3 to abut against and adhere to the window glass again.
[0037] This invention provides another technical solution: (Refer to...) Figures 1-2A window assembly includes a window frame 10 and a window glass 20 installed in the window frame 10, and also includes the aforementioned waterproof strip 40, which is embedded in the opening side of the window frame 10 and abuts against the outer side of the window glass 20. A mounting groove 11 is formed on one side of the opening of the window frame 10, and the mounting groove 11 is adapted to the mounting strip 2 on the waterproof strip 40. When installing the waterproof strip 40, the mounting strip 2 on the waterproof strip 40 is slidably embedded in the mounting groove 11, and then the rigid support frame 22 is embedded into the strip opening 21 in the mounting strip 2. The opening of the mounting groove 11 is a narrowing structure, that is, its opening width is smaller than its inner width. The opening width of the mounting groove 11 is the same as the width at the connection between the mounting strip 2 and the strip body 1. The width of the rigid support frame 22 is greater than the width at the connection between the mounting strip 2 and the strip body 1, and is also greater than the width of the opening of the mounting groove 11. By inserting the rigid support frame 22, the mounting strip 2 is limited and fixed to prevent it from falling off. The outer side of the rigid support frame 22 directly abuts against the inner wall of the mounting groove 11 through the opening on the strip opening 21. A rubber strip 30 is installed on the other side of the opening of the window frame 10, and the rubber strip 30 abuts against the inner side of the window glass 20.
[0038] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
