Description

Technical Field

[0001] This utility model relates to the field of automotive sealing components technology, specifically a sealing strip for automotive windows that is easy to replace. Background Technology

[0002] As a key sealing component of the car body, automotive window sealing strips are mainly installed between the window guide channel and the window glass. Their core function is to block the flow of air between the inside and outside of the car, and to prevent the intrusion of external dust and rainwater. At the same time, they play a role in buffering and shock absorption and reducing friction noise during the raising and lowering of the window, directly affecting the car's sealing performance, sound insulation, comfort and service life.

[0003] The prior art patent document CN210617824U provides a sealing strip for automobile windows. By designing the first limb as a cuboid structure and partially bending it, the two ends of the first limb are connected to the base plate and the second limb respectively. This structural design gives the second limb elasticity, which facilitates the opening and closing of the second limb, thereby facilitating the combination of the glass and the second limb. To a certain extent, it optimizes the assembly compatibility between the window glass and the sealing strip.

[0004] While the aforementioned existing technologies improve the elasticity and cushioning capacity of the sealing strip, they rely on a single sealing structure to achieve a seal during use. This results in a small sealing contact area and limited sealing effect. When the vehicle experiences bumps or temperature changes cause component deformation, sealing gaps are prone to occur, making it impossible to achieve double sealing protection and ensuring sealing reliability during long-term use. Therefore, we need a sealing strip for automotive windows that is easy to replace. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing strip for automobile windows that is easy to replace, so as to solve the problems mentioned in the background art that the existing automobile window sealing strips only use a single sealing structure, cannot achieve double sealing, and have limited sealing effect.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a sealing strip for easy replacement of automobile windows, comprising a sealing strip body, wherein a first sealing component is provided on the upper inner side of the sealing strip body, and a second sealing component is provided on the lower inner side of the sealing strip body; The first sealing component includes a rubber bend, and one end of the rubber bend is integrally formed with a rubber inclined portion. One end of the rubber inclined portion is provided with a rubber arc end, and the outer walls of both the rubber inclined portion and the rubber arc end are composited with a flocking layer. The second sealing assembly includes a hollow rubber seat, and one end of the hollow rubber seat is provided with an arc-shaped lip. The inner wall of the hollow rubber seat is provided with a hollow groove, and the inner wall of the hollow rubber seat is provided with a first elastic sponge core and a second elastic sponge core.

[0007] Preferably, the inner bottom of the sealing strip body is provided with an arc-shaped rubber sheet, and the bottom of the sealing strip body is provided with a snap-fit ​​part, and the outer side of the snap-fit ​​part is provided with an arc-shaped rubber block.

[0008] Preferably, there are two snap-fit ​​parts, and the two snap-fit ​​parts are symmetrically arranged with the vertical line of the sealing strip body as the axis of symmetry.

[0009] Preferably, there are two rubber arc-shaped blocks, and the two rubber arc-shaped blocks are symmetrically arranged with the vertical line of the snap-fit ​​part as the axis of symmetry.

[0010] Preferably, the bottom of the snap-fit ​​part is provided with a fixing groove spaced apart along the length direction, and a magnetic adsorption layer is fixedly bonded to the inner wall of the fixing groove. The magnetic adsorption layer can form a magnetic attraction with the metal patch preset in the window guide groove. The magnetic adsorption layer is specifically a flexible permanent magnet sheet structure.

[0011] Preferably, there are two first sealing components, and the two first sealing components are symmetrically arranged with the vertical line of the sealing strip body as the axis of symmetry, and the flocking layer is nylon flocking.

[0012] Preferably, there are two second sealing components, and the two second sealing components are symmetrically arranged with the vertical line of the sealing strip body as the axis of symmetry.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are: First, in this utility model, the rubber curved part and the rubber inclined part of the first sealing component form an elastic clamping structure, which, together with the rubber arc end, can tightly fit the outer wall of the car window glass. By setting a nylon flocking layer, the friction noise when the car window glass is raised and lowered can be reduced, and the sealing gap can be further reduced to achieve the first seal. The arc lip in the second sealing component forms the second seal. The first elastic sponge core and the second elastic sponge core inside the hollow groove can deform elastically to make the arc lip fit the car window glass. Even if the vehicle is bumpy or the temperature changes cause slight deformation of the components, the double sealing structure can still maintain the sealing performance. The double sealing structure formed by the cooperation of the first sealing component and the second sealing component solves the problem of small sealing contact area and easy gap in the prior art.

[0014] Secondly, this utility model features a double snap-fit ​​part at the bottom of the sealing strip body, which can quickly form a snap-fit ​​with the slot of the window guide channel to achieve initial fixation. At the same time, the magnetic adsorption layer in the fixing groove at the bottom of the snap-fit ​​part can magnetically attract the metal patch preset in the window guide channel. Through the double fixing structure, the cumbersome installation problem caused by the reliance on glue for traditional sealing strips is avoided. It also ensures that the sealing strip will not shift or loosen after installation. Installation can be completed without professional tools, which lowers the installation threshold for users and facilitates replacement. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-4 As shown, a car window sealing strip that is easy to replace includes a sealing strip body 1, a first sealing component 2 is provided on the upper inner side of the sealing strip body 1, and a second sealing component 3 is provided on the lower inner side of the sealing strip body 1. The first sealing component 2 includes a rubber bending portion 201, and a rubber inclined portion 202 is integrally formed at one end of the rubber bending portion 201. A rubber arc end 203 is provided at one end of the rubber inclined portion 202, and a flocked layer 204 is composited on the outer wall of both the rubber inclined portion 202 and the rubber arc end 203. The second sealing assembly 3 includes a hollow rubber seat 301, and one end of the hollow rubber seat 301 is provided with an arc-shaped lip 302. The inner wall of the hollow rubber seat 301 is provided with a hollow groove 303, and the inner wall of the hollow rubber seat 301 is provided with a first elastic sponge core 304 and a second elastic sponge core 305.

[0019] Through the above technical solution, the first sealing component 2, through the elastic deformation of the rubber bending part 201, drives the rubber inclined part 202 and the rubber arc end 203 to tightly fit against the outer wall of the car window glass, forming a first flexible seal, which can initially block the flow of air and dust; the flocked layer 204 can reduce the friction noise when the glass is raised and lowered, and at the same time fill the small unevenness of the glass surface, reduce the sealing gap, and avoid wear on the sealing surface; the hollow rubber seat 301 and the arc lip 302 of the second sealing component 3 form a second seal, and with the double elastic sponge core in the hollow groove 303, the arc lip 302 can be tightly fitted against the glass through elastic deformation, filling the gap. Even if the vehicle bumps or temperature changes cause slight deformation of the component, the double elastic sponge core can still make the arc lip 302 fit against the car window glass by providing elasticity, maintaining the sealing contact, further enhancing the waterproof and sound insulation effect, and solving the problem of gaps easily occurring in the existing single seal.

[0020] Specifically, an arc-shaped rubber sheet 4 is provided at the bottom inner part of the sealing strip body 1, and a snap-fit ​​part 5 is provided at the bottom of the sealing strip body 1, with an arc-shaped rubber block 6 provided on the outer side of the snap-fit ​​part 5.

[0021] Through the above technical solution, the arc-shaped rubber sheet 4 has good elasticity. When the car window glass moves and comes into contact with the arc-shaped rubber sheet 4, the pressure causes the arc-shaped rubber sheet 4 to deform, which plays a buffering role.

[0022] Specifically, there are two snap-fit ​​parts 5, and the two snap-fit ​​parts 5 are symmetrically arranged with the vertical line of the sealing strip body 1 as the axis of symmetry.

[0023] By employing the above technical solution and using two symmetrically arranged snap-fit ​​parts 5, the installation of the sealing strip body 1 in the window guide groove can be made more stable, avoiding tilting or displacement of the sealing strip body 1 due to unilateral force.

[0024] Specifically, there are two rubber arc-shaped blocks 6, and the two rubber arc-shaped blocks 6 are symmetrically arranged with the vertical line of the snap-fit ​​part 5 as the axis of symmetry.

[0025] With the above technical solution, during the installation process, by aligning the snap-fit ​​part 5 with the slot of the window guide groove and pressing gently, the snap-fit ​​part 5, along with the rubber arc-shaped block 6, is inserted into the guide groove. The rubber arc-shaped block 6 cooperates with the arc-shaped groove in the guide groove, and the rubber arc-shaped block 6 plays a limiting role, making the snap-fit ​​part 5 less likely to fall off, thus completing the initial fixation of the sealing strip body 1. No complicated operation steps are required, simplifying the installation process and laying a convenient foundation for subsequent replacement work.

[0026] Specifically, the bottom of the snap-fit ​​part 5 is provided with a fixing groove 7 spaced apart along the length direction. A magnetic adsorption layer 8 is fixedly bonded to the inner wall of the fixing groove 7. The magnetic adsorption layer 8 can form a magnetic attraction with the metal patch preset in the window guide groove. The magnetic adsorption layer 8 is specifically a flexible permanent magnet sheet structure.

[0027] Through the above technical solution, the magnetic adsorption layer 8 adopts a flexible permanent magnet sheet structure, which has good magnetism and flexibility. After the sealing strip body 1 is initially fixed to the window guide groove through the snap-fit ​​part 5, the magnetic adsorption layer 8 can form a tight magnetic attraction with the metal patch preset in the window guide groove. This magnetic attraction method can, on the one hand, fix the sealing strip body 1 a second time, enhance the stability of the sealing strip body 1 in the window guide groove, and effectively avoid the displacement and loosening problems that are easy to occur when the traditional sealing strip is fixed by only relying on buckles or glue. On the other hand, the flexible structural characteristics allow the magnetic adsorption layer 8 to better adapt to the shape of the window guide groove. Even if there are slight irregularities in the window guide groove, the magnetic adsorption layer 8 can maintain a good attraction state with the metal patch through its own deformation, ensuring the stability of the fixing effect. In addition, compared with glue bonding, the magnetic adsorption method does not require waiting for the glue to cure, which is more efficient in installation. Moreover, when replacing the sealing strip in the future, only a certain external force needs to be applied to separate the magnetic adsorption layer 8 from the metal patch, which is simple and convenient to operate and reduces the difficulty and cost of replacement.

[0028] Specifically, there are two first sealing components 2, and the two first sealing components 2 are symmetrically arranged with the vertical line of the sealing strip body 1 as the axis of symmetry, and the flocking layer 204 is nylon flocking.

[0029] Through the above technical solution, the two symmetrically arranged first sealing components 2 can seal the window glass from both sides, making the seal more comprehensive and uniform. When the window glass is raised or lowered, the first sealing components 2 on both sides can simultaneously contact the outer wall of the window glass, avoiding the problem of uneven sealing caused by single-sided sealing, and further improving the sealing reliability. The flocked layer 204 is made of nylon flocked material. Nylon has good wear resistance, flexibility and chemical stability. During the raising and lowering of the window glass, the nylon flocked layer 204 can effectively reduce the coefficient of friction between the glass and the rubber inclined part 202 and the rubber arc end 203, reducing friction noise. At the same time, the fluffy structure of the nylon flock can fill the small unevenness on the surface of the window glass, reduce the sealing gap, enhance the sealing effect, and its good wear resistance can ensure that the flocked layer 204 is not easy to fall off or wear during long-term use, extending the service life of the sealing strip.

[0030] Specifically, there are two second sealing components 3, and the two second sealing components 3 are symmetrically arranged with the vertical line of the sealing strip body 1 as the axis of symmetry.

[0031] Through the above technical solution, two symmetrically arranged second sealing components 3 cooperate with the first sealing component 2 to form a double sealing structure; a second sealing line is formed from both sides of the window glass, which can further enhance the sealing performance; when the vehicle is bumpy or the temperature changes cause slight deformation of the components, the second sealing components 3 on both sides can use their own structural characteristics to seal and compensate the window glass from both sides, ensuring that the sealing surface always maintains tight contact, effectively preventing sealing problems caused by unilateral sealing failure, and improving the sealing stability and durability of the sealing strip under complex working conditions.

[0032] In use, when the car window glass first contacts the first sealing component 2, the outer wall of the car window glass will compress the rubber inclined part 202. The rubber inclined part 202 causes the rubber curved part 201 to undergo elastic deformation, which in turn causes the rubber inclined part 202 and the rubber arc end 203 to bring the flocked layer 204 to fit the car window glass, forming the first flexible sealing barrier. As the car window glass continues to extend into the inner side of the sealing strip body 1, it will compress the arc lip 302. The arc lip 302 will cause the hollow rubber seat 301 and the first elastic sponge core 304 and the second elastic sponge core 305 to move together. 5. Elastic deformation occurs, with the double elastic sponge core ensuring good elasticity and rebound effect, ensuring that the arc-shaped lip 302 can fit well with the car window glass, forming a second seal, effectively solving the problem of gaps that easily occur in traditional single seals, and further enhancing the waterproof and sound insulation effects; the car window glass continues to extend and press against the arc-shaped rubber sheet 4, and the arc-shaped rubber sheet 4 absorbs the pressure when the glass moves through its own elastic deformation, playing a buffering role. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
