Description

Technical Field

[0001] This application relates to the field of vehicle accessories technology, and in particular to card strips and vehicles. Background Technology

[0002] The clip structure, as a core component for sealing the vehicle's exterior, assembling and positioning, and reducing wind noise, is widely used in the bottom assembly position of the windshield of various passenger and commercial vehicles to achieve matching installation and connection between the vehicle's ventilation cover and the windshield, so as to obtain a better appearance matching effect.

[0003] The matching relationship between the clip structure and surrounding parts in the related technology is as follows: a metal frame is set inside the clip structure, the clip feet of the ventilation cover are engaged with the clip structure through the barbs of the clip, and the clip structure is also bonded to the windshield with double-sided tape.

[0004] However, the assembly and adaptability of the clip structure in related technologies are poor. The functional structures of the existing clip structure, such as sealing, buffering, anti-reverse, and insertion / extraction force adjustment, are relatively independent and dispersed. For windshields of different thicknesses and ventilation covers of different shapes, the clip cross-section needs to be redesigned separately, resulting in a variety of cross-section development options, long development cycles, and high mold investment costs. At the same time, the split structure results in a stiff insertion / extraction feel during vehicle assembly, poor fit between functional areas, and various quality problems such as poor sealing, local loosening, and anti-reverse failure after assembly. Summary of the Invention

The distance between the free end and the inner wall of one side of the slot is greater than the distance between the damping adjustment part and the inner wall of one side of the slot.

[0013] In one embodiment, the anti-detachment part is set at an angle to the inner wall of one side of the card slot, and the angle between the anti-detachment part and the inner wall of one side of the card slot is α, where 80°≤α≤100°.

[0014] In one embodiment, the elastic element further includes a sealing part and a connecting part. The sealing part is disposed on the inner wall of the slot near the glass and is used to seal against the cover plate body of the structural element. The sealing part is connected to the connecting part and is disposed between the cover plate body and the glass. The top of the main body of the card strip near the glass is provided with a support part that extends obliquely toward the glass. The connecting part is connected to the support part. The sealing part, the connecting part and the support part together form a second buffer chamber.

[0015] In one embodiment, the anti-detachment part, the damping adjustment part, and the support part are all disposed on the inner side wall of the slot near the glass; the sealing part is connected to the damping adjustment part on the side away from the connecting part; the second buffer chamber is formed by the sealing part, the connecting part, the support part, and the supporting part.

[0016] In one embodiment, the anti-detachment part, the support part, the damping adjustment part, the sealing part, and the connecting part are an integrated structure.

[0017] In one embodiment, the elastic element is integrally extruded with the card strip body.

[0018] In one embodiment, the wall thickness of the sealing part near the end of the support part is set as D1, the maximum wall thickness of the middle part of the sealing part is set as D2, and the wall thickness of the sealing part near the end of the connecting part is set as D3; wherein, D2 > D3 > D1.

[0019] In one embodiment, D1 / D2 = 0.3-0.8; and / or, D3 / D2 = 0.6-0.9.

[0020] In one embodiment, the card strip body includes a skeleton and a covering layer, the covering layer covering the skeleton; the skeleton is made of an integrally extruded metal profile or an integrally injection molded plastic part, and the covering layer is made of a rigid material.

[0021] In one embodiment, the abutting portion and the covering layer are made of the same material and are an integral structure; or, the abutting portion and the elastic element are made of the same material and are an integral structure.

[0024] In one embodiment, the card strip body is provided with an mounting part and a second buffer part, the mounting part being used to mount the glass; the second buffer part is connected to the bottom of the card strip body on the side opposite to the mounting part.

[0025] On the other hand, this application also provides a means of transportation, including the aforementioned card bar, as well as glass and structural components, wherein the card bar is connected between the glass and the structural components.

[0026] The aforementioned locking strip and vehicle, based on the specific structural shape of the elastic element and the cooperative relationship between the damping adjustment part and the abutment part, allow the locking hook of the structural element to compress the anti-detachment part during the process of inserting the structural element into the slot. The damping adjustment part is adaptively stretched, allowing the locking hook to smoothly engage in the slot, thus achieving the engagement between the locking strip and the structural element, facilitating assembly. When the structural element is pulled out of the slot, since the first convex surface of the damping adjustment part faces the first buffer cavity, the anti-detachment part, under the compression of the locking hook, will cause the damping adjustment part to deform towards the first buffer cavity, that is, to bend and deform towards the abutment part, causing the first convex surface and the abutment part to abut against each other. The abutment part can prevent the damping adjustment part from continuing to deform, increasing the pull-out resistance of the structural element, effectively preventing the structural element from falling out of the slot, and improving the anti-reverse stability.

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] See Figure 1 This application provides an embodiment of a means of transportation, including but not limited to automobiles, buses, trains, etc., which can be flexibly adjusted and configured according to actual needs. This application will specifically use an automobile as an example of a means of transportation.

[0039] For example, the vehicle includes glass 10, a retaining strip 20, and structural component 30. Glass 10 is mounted on the vehicle body, specifically the windshield. Glass 10 may be, but is not limited to, single-pane or laminated glass, depending on actual needs. Retaining strip 20 is mounted on glass 10, specifically fixed to glass 10 by adhesive. Retaining strip 20 secures structural component 30 and prevents structural component 30 from loosening, forming a sealed and stable connection between structural component 30 and glass 10. Of course, structural component 30 can also be detached when needed. Structural component 30 can be a ventilation cover or a ventilation grille.

[0040] Specifically, the structural component 30 includes a cover plate body 31 and a latch 32. The latch 32 is connected to the cover plate body 31. The latch 32 is used to engage with the latch strip 20. When the latch 32 and the latch strip 20 are engaged, the structural component 30 is connected to the glass 10; when the latch 32 is separated from the latch strip 20, the structural component 30 is separated from the glass 10.

[0041] Please see Figure 1 , Figure 2 and Figure 4 An embodiment of this application provides a retaining strip 20, including a retaining strip body 21, an elastic member 22, and an abutment portion 23. The retaining strip body 21 is used for installation between the glass 10 and the structural member 30. The retaining strip body 21 is provided with a retaining groove 211, which is used for engaging with the retaining hook 32 of the structural member 30. Optionally, the retaining groove 211 may include, but is not limited to, a U-shaped groove or other regular or irregular shapes, and is not particularly limited here.

[0042] Optionally, the main body 21 of the card strip includes two support plates 212 and a base plate 213. The two support plates 212 are arranged at intervals relative to each other and are connected by the base plate 213, forming a card groove 211. The main body 21 of the card strip also includes a mounting part 214. The mounting part 214 is connected to one of the support plates 212 and is used to mount the glass 10. The mounting part 214 is provided with an adhesive component 215, such as adhesive tape. The glass 10 is bonded and fixed to the mounting part 214 by the adhesive component 215.

[0043] The elastic element 22 is connected to the inner wall of the slot 211. The inner wall of the slot 211 is also any side of the two support plates 212 facing each other. Optionally, there is only one elastic element 22, which can be provided on any side of the two support plates 212 facing each other, that is, on the inner wall of any side of the slot 211. See details in [reference needed]. Figures 1 to 7 The elastic elements 22 are all located in the slot 211 near the inner wall of the glass 10. See also... Figure 8 , Figure 8 The diagram shows that the elastic element 22 can also be disposed in the slot 211 away from the inner wall of the glass 10.

[0044] In addition, there can be two elastic elements 22. The two elastic elements 22 are respectively provided on the two sides of the two support plates 212 facing each other. That is, the two inner sidewalls opposite to the slot 211 are provided with elastic elements 22, so as to achieve stable snap-fit ​​fixing of the structural member 30.

[0045] In this embodiment, the elastic element 22 is specifically arranged in the slot 211 near the inner wall of the glass 10 as an example. Figures 1 to 7 As shown.

[0046] Please see Figure 1 , Figure 2 and Figure 4For example, the elastic element 22 includes an anti-detachment part 221, a damping adjustment part 222, and a support part 223. Both the anti-detachment part 221 and the support part 223 are connected to one side of the inner wall of the slot 211, and are also connected via the damping adjustment part 222. The anti-detachment part 221 and the support part 223 support the damping adjustment part 222, ensuring stability during backlash prevention. The anti-detachment part 221 is closer to the bottom wall of the slot 211 than the support part 223, and can engage with the hook 32 extending into the slot 211, preventing the hook 32 from detaching from the slot 211. Optionally, the support part 223 is located at the top of one side of the inner wall of the slot 211, opposite to the top of the other side of the inner wall of the slot 211, thus limiting the width of the slot opening of the slot 211. Therefore, by adjusting the size of the support 223, the slot width of the card slot 211 can be adjusted adaptively.

[0047] The abutment portion 23 is disposed on one side of the inner wall of the slot 211, and is located between the anti-detachment portion 221 and the support portion 223. The anti-detachment portion 221, the support portion 223, the damping adjustment portion 222, and the abutment portion 23 together form a first buffer chamber 2201. The damping adjustment portion 222 has a first convex surface 2221 protruding into the first buffer chamber 2201. When the structural member 30 is pulled outward from the slot 211, the anti-detachment portion 221, under the pressure of the hook 32, causes the damping adjustment portion 222 to bend and deform towards the abutment portion 23, so that the first convex surface 2221 abuts against the abutment portion 23.

[0048] Based on the specific structural shape of the elastic element 22 and the cooperation between the damping adjustment part 222 and the abutment part 23, the aforementioned locking strip 20 and vehicle, during the process of inserting the structural component 30 into the locking slot 211, the locking hook 32 of the structural component 30 can squeeze the anti-detachment part 221, and the damping adjustment part 222 is adaptively stretched, so that the locking hook 32 can smoothly lock into the locking slot 211, thereby realizing the locking connection between the locking strip 20 and the structural component 30, which is convenient for assembly; when the structural component 30 is pulled out from the locking slot 211, due to the damping adjustment The first convex surface 2221 of the entire part 222 faces into the first buffer chamber 2201. In this way, the anti-disengagement part 221 will cause the damping adjustment part 222 to deform into the first buffer chamber 2201 under the pressure of the hook 32, that is, to bend and deform towards the abutment part 23, so that the first convex surface 2221 and the abutment part 23 abut against each other. The abutment part 23, the damping adjustment part 222 and the hook 32 come into contact and squeeze together to form a resistance to the pull-out of the hook 32, which can effectively prevent the structural part 30 from coming out of the slot 211 and improve the stability of the anti-retraction.

[0049] In addition, the damping adjustment part 222 has good fatigue resistance and is not easily deformed or damaged due to the connection with the anti-detachment part 221.

[0050] For example, the damping adjustment section 222 includes, but is not limited to, a curved portion. Thus, due to the presence of the first buffer chamber 2201 and the curved portion of the damping adjustment section 222, the elastic member 22 can be adaptively stretched when subjected to force, and the deformation of the elastic member 22 can compensate for the tolerances of the structural member 30, enabling it to adapt to glass 10 of different thicknesses and different types of ventilation covers, thereby reducing product adaptation, mold development, and manufacturing costs.

[0051] To further improve the stability of the backstop, for example, the abutment portion 23 is provided with a second convex surface 231 protruding toward the damping adjustment portion 222. When the structural member 30 is in an unloaded state, the second convex surface 342 is spaced apart from the first convex surface 2221; when the structural member 30 is pulled outward from the slot 211, the second convex surface 231 abuts against the first convex surface 2221. The first convex surface 2221 and the second convex surface 231 are each, but are not limited to, arcuate surfaces or other regular and irregular shapes, and are not particularly limited here.

[0052] When the anti-detachment part 221 is not subjected to outward pressure from the structural member 30, the first convex surface 2221 and the second convex surface 231 are spaced apart. The space between the first convex surface 2221 and the second convex surface 231 belongs to the first buffer chamber 2201, which plays a buffering role and provides buffer deformation space for the structural member 30 to be pulled outward from the slot 211. When the outward pulling force of the structural member 30 is greater than the preset value, the first convex surface 2221 and the second convex surface 231 abut against each other after the damping adjustment part 222 bends. The damping adjustment part 222 can further deform and squeeze the abutting part 23 until the structural member 30 is pulled out of the slot 211. When the outward pulling force of the structural member 30 is less than the preset value, the damping adjustment part 222 is limited by the abutting part 23 to prevent the structural member 30 from being pulled outward, that is, it can prevent the structural member 30 from being easily pulled outward, and enhance the stability of the structural member 30 in the slot 211.

[0053] The hook 32 is provided with a first holding part 321. The first holding part 321 is located on the side of the hook 32 facing the inner wall of the slot 211. A second holding part 322 is provided on the other side of the hook 32, and a third holding part 2111 is provided on the inner wall of the slot 211 away from the elastic member 22. After the hook 32 extends into the slot 211, the first holding part 321 engages with the anti-disengagement part 221, and the second holding part 322 engages with the third holding part 2111, thereby preventing the first holding part 321 from being pulled outward. Specifically, the first holding part 321 and the second holding part 322 are protrusions that protrude from the side wall of the hook 32. The outline of the protrusions is arc-shaped or an inclined surface that forms an angle with the side wall of the hook 32, preventing jamming during insertion and removal and allowing the insertion and removal action to be completed smoothly.

[0054] Please see Figure 1 , Figure 2 and Figure 4 Based on the aforementioned embodiment, the damping adjustment part 222 has a concave surface 2222 formed on the side away from the abutment part 23. Thus, on the one hand, during the process of inserting the structural member 30 into the slot 211, the damping adjustment part 222 can be adaptively stretched under force, allowing the hook 32 to smoothly engage in the slot 211; on the other hand, when the structural member 30 is pulled outward from the slot 211, the concave surface 2222 can guide the damping adjustment part 222 to bend and deform towards the abutment part 23, meaning that the damping adjustment part 222 will not bend and deform away from the abutment part 23 after being subjected to compressive force. This ensures that the damping adjustment part 222 and the abutment part 23 abut and limit each other after bending deformation, improving anti-detachment stability.

[0055] Based on the aforementioned embodiment, the damping adjustment part 222 is connected to the middle portion of the anti-detachment part 221. The end of the anti-detachment part 221 furthest from one side of the inner wall of the slot 211 is a free end 2211, and the distance between the free end 2211 and one side of the inner wall of the slot 211 is greater than the distance between the damping adjustment part 222 and one side of the inner wall of the slot 211. That is, compared to the damping adjustment part 222, the free end 2211 protrudes towards the other side of the inner wall of the slot 211. Thus, the anti-detachment part 221 and the damping adjustment part 222 cooperate to form a recess. When the structural member 30 is pulled outward, the recess guides the damping adjustment part 222 to bend and deform towards the abutment part 23, thereby preventing the damping adjustment part 222 from bending and deforming away from the abutment part 23.

[0056] Optionally, the concave surface 2222 may be, but is not limited to, an arc-shaped surface or other regular or irregular shapes.

[0057] Please see Figures 5 to 7 ,and Figures 1 to 4 The main difference in the structure shown is that the specific connection positions of the damping adjustment part 222 and the anti-detachment part 221 can be different, and the specific connection positions can be flexibly adjusted according to actual needs. In some other embodiments, the damping adjustment part 222 and the anti-detachment part 221 are connected to the end of one side of the inner wall away from the slot 211. Specifically, the damping adjustment part 222 and the anti-detachment part 221 are set at an acute angle. On the one hand, during the insertion of the structural component 30, the damping adjustment part 222 guides the hook 32, achieving smooth engagement, high assembly efficiency, and reducing the assembly defect rate; on the other hand, when the structural component 30 is pulled out, it can effectively prevent the structural component 30 from falling out of the slot 211, providing good anti-reverse stability. In addition, it has good fatigue resistance and is not easily deformed or damaged.

[0058] Please refer to the following: Figures 1 to 4For example, the anti-detachment part 221 and the inner wall of one side of the slot 211 are arranged at an angle, and the angle between the anti-detachment part 221 and the inner wall of one side of the slot 211 is α, where 80°≤a≤100°. Optionally, α may include, but is not limited to, 80°, 85°, 90°, 95° or 100°, etc., and can be flexibly selected according to actual needs, without limitation here. In this way, the angle α is set more appropriately, which not only has good anti-retardation stability, but also good insertion and removal feel.

[0059] Specifically, in this embodiment, 'a' is preferably set to 90°. It can be understood that when 'a' is greater than 90°, and the anti-detachment part 221 is tilted toward the side of the damping adjustment part 222, the anti-retardation stability decreases as 'a' increases; when 'a' is less than 90°, and the anti-detachment part 221 is tilted toward the side away from the damping adjustment part 222, as 'a' increases, a great deal of force will be required to disengage the hook 32 from the slot 211, which can easily lead to severe deformation and damage of the elastic element 22, or even jamming.

[0060] Please refer to the following: Figure 1 , Figure 2 and Figure 4 Based on the aforementioned embodiments, the elastic member 22 further includes a sealing portion 224 and a connecting portion 225. The sealing portion 224 connects the damping adjustment portion 222 and the connecting portion 225, and is used to seal against the cover plate body 31 of the structural member 30, providing a better sealing effect and effectively preventing dust and water. The connecting portion 225 is used to be disposed between the cover plate body 31 and the glass 10, and can fill the gap between the cover plate body 31 and the glass 10. Furthermore, by adjusting the wall thickness and / or the arc surface design of the connecting portion 225, a smoother appearance surface connection effect can be formed while satisfying the filling function.

[0061] Based on the aforementioned embodiment, the top of the main body 21 of the card strip near the glass 10 is provided with a support portion 216 extending obliquely towards the glass 10. The connecting portion 225 is connected to the support portion 216, and the support portion 216 serves to support the sealing portion 224 and the connecting portion 225. The sealing portion 224, the connecting portion 225, the support portion 223, and the support portion 216 together form a second buffer chamber 2202. Thus, when the hook 32 of the structural component 30 is fully inserted into the slot 211, the cover plate body 31 contacts and presses the sealing portion 224, causing the sealing portion 224 to deform inward toward the second buffer chamber 2202. This ensures the effective contact area between the sealing portion 224 and the cover plate body 31, forming a good sealing effect, effectively preventing rainwater, dust, noise, and airflow from entering the vehicle, and improving the overall sealing, sound insulation, and waterproof performance of the vehicle. Furthermore, the cover plate is pushed to its final installation position, and the sealing part 224 is in close contact with the cover plate body 31, which can support the cover plate body 31 and effectively absorb the vibration of the structural component 30 during use. This effectively prevents the retaining strip 20 from moving backward, loosening, or shifting due to vehicle vibration or external pulling, ensuring long-term assembly stability. In addition, due to the second buffer space, the deformation of the elastic element 22 can compensate for the tolerance of the structural component 30 and can be adapted to different thicknesses of glass 10 and different types of ventilation covers, thereby reducing product adaptation, mold development, and manufacturing costs.

[0062] For example, the anti-slip part 221, support part 223, damping adjustment part 222, sealing part 224, and connecting part 225 are an integrated structure. Specifically, the anti-slip part 221, support part 223, damping adjustment part 222, sealing part 224, and connecting part 225 are integrally molded by injection molding. More specifically, each component of the elastic element 22 is integrally injection molded with the main body 21 of the retaining strip. Thus, during the process of inserting the hook 32 of the structural component 30 into the slot 211, the hook 32 acts on the anti-detachment part 221, which not only causes the anti-detachment part 221 and the damping adjustment part 222 to deform, but also simultaneously causes the sealing part 224, the support part 223 and the connecting part 225 to deform, which can make room for the sealing contact position of the structural component 30, reduce the insertion force during installation, and match the thickness of each part of the anti-detachment part 221, the damping adjustment part 222, the sealing part 224, the connecting part 225 and the support part 223, so that the insertion force value can be adjusted according to the assembly requirements.

[0063] Furthermore, the sealing, buffering, insertion / extraction force adjustment, and anti-reverse functions are integrated into the elastic element 22, simplifying the structure and reducing development and production costs. When dealing with glass 10 of different thicknesses and structural components 30 of different specifications, only minor adjustments to the local dimensions of the elastic element 22 are required, eliminating the need to redesign the cross-section of the retaining strip 20 as a whole. This significantly reduces the difficulty of cross-section development, the number of molds required, and R&D investment, effectively helping customers control overall production costs.

[0064] In addition, after the functions are integrated, the deformation synchronization of each area of ​​the elastic component 22 is better, the sealing surface fits more tightly, and the waterproof, dustproof and sound insulation effects are significantly improved. After the various components of the elastic component 22 are set as an integrated structure, the overall strength is higher. Under the long-term vibration of vehicle driving and changes in high and low temperature environment, it is not easy to have problems such as backstop failure, local loosening and sealing gaps. The product's durability and stability in use are greatly enhanced.

[0065] The elastic element 22 may be made of, but is not limited to, soft rubber materials. Optionally, the material used for the elastic element 22 may include, but is not limited to, soft TPE (thermoplastic elastomer) or TPV (thermoplastic vulcanizate), etc. There are no special restrictions here, and it can be flexibly adjusted and set according to actual needs.

[0066] In some embodiments, please refer to Figures 1 to 4 The abutting part 23 and the elastic element 22 are an integral structure. Specifically, the abutting part 23 and the elastic element 22 are made of the same material and are obtained by integral injection molding.

[0067] Of course, please see Figures 5 to 7 In other embodiments, the abutment portion 23 may also be made of the same material as the card strip body 21. That is, the "abutment portion 23" in this embodiment may be a "part of the card strip body 21", that is, the "abutment portion 23" and the "other parts of the card strip body 21" are integrally formed; or it may be an independent component that can be separated from the "other parts of the card strip body 21", that is, the "abutment portion 23" may be manufactured independently and then combined with the "other parts of the card strip body 21" to form a whole.

[0068] Please refer to the following: Figure 4 For example, the wall thickness of the sealing portion 224 near the support portion 223 is set as D1, the maximum wall thickness of the middle portion of the sealing portion 224 is set as D2, and the wall thickness of the sealing portion 224 near the connecting portion 225 is set as D3. Wherein, D2 > D3 > D1. Specifically, along the insertion and removal direction of the structural member 30, the thickness of the sealing portion 224 gradually increases first and then gradually decreases. Since D1 < D3, during the insertion of the structural member 30, the end of the sealing portion 224 near the support portion 223 sinks down first than the end of the sealing portion 224 near the connecting portion 225, ensuring a flat appearance surface. Furthermore, based on D2 > D3 > D1, while the sealing portion 224 is recessed towards the second buffer chamber 2202, the effective contact area between its outer side and the structural member 30 can be further optimized. Conversely, when D1 > D3, during the insertion of the structural member 30, the end of the sealing part 224 closer to the connecting part 225 sinks down first than the end of the sealing part 224 closer to the supporting part 223, resulting in an uneven appearance.

[0069] For example, D1 / D2 = 0.3-0.8. Specifically, D1 / D2 = 0.3, 0.4, 0.5, 0.6, 0.7, or 0.8, etc., without limitation. If D1 / D2 < 0.3, the deformation of the middle part of the sealing part 224 is insufficient, resulting in gaps and poor sealing; if D1 / D2 > 0.8, the yield thickness of the sealing part 224 near the end of the support part 223 is too large, and the sealing part 224 will deform downward as a whole, resulting in an uneven appearance.

[0070] For example, D3 / D2 = 0.6-0.9. Specifically, D3 / D2 = 0.6, 0.7, 0.8, or 0.9, etc., without limitation. If D3 / D2 < 0.6, the supporting force is insufficient, and the end of the sealing part 224 near the connecting part 225 will deform downward first, resulting in an uneven appearance. Conversely, if D3 / D2 > 0.9, the end of the sealing part 224 near the connecting part 225 will bulge upward, and the end of the sealing part 224 near the connecting part 225 will deform upward, resulting in an uneven appearance.

[0071] For example, the main body 21 of the card strip includes a skeleton 2101 and a covering layer 2102, with the covering layer 2102 covering the skeleton 2101. The skeleton 2101 serves as the core support, ensuring the overall structural strength of the main body 21 of the card strip. Alternatively, it can be understood that both the support plate 212 and the base plate 213 include a skeleton 2101 and a covering layer 2102. The skeleton 2101 is located both within the support plate 212 and the mounting plate, ensuring the structural strength of both the support plate 212 and the mounting plate. The covering layer 2102 protects the skeleton 2101, preventing it from being exposed and oxidizing / rusting. Simultaneously, it serves as a rigid positioning base, achieving precise positioning and rigid fit between the card strip 20 and the vehicle body mounting groove, bearing the main load-bearing and shaping functions.

[0072] Optionally, the frame 2101 can be made of an integrally extruded metal profile or an integrally injection-molded plastic part. In this embodiment, the frame 2101 is made of aluminum profile, which is lightweight, rigid, resistant to bending, and has high dimensional accuracy. It can maintain the overall shape of the clip 20 without deformation for a long time, adapting to the complex operating conditions of vehicles. At the same time, the metal frame 2101 can improve the overall anti-aging and anti-compression capabilities of the clip 20, extending the product's service life.

[0073] Optionally, the covering layer 2102 is made of a rigid material, and the hardness of the material of the covering layer 2102 is greater than that of the elastic element 22. Specifically, the covering layer 2102 is made of, but is not limited to, rigid PP (polypropylene), rigid PVC, or modified ABS, and other commonly used automotive plastic materials. The material can be flexibly selected according to different actual needs and the climate conditions of the region of use. In this embodiment, the covering layer 2102 is specifically made of rigid PP (polypropylene). Rigid PP has the characteristics of high hardness, wear resistance, low temperature resistance, resistance to automotive environmental aging, good molding performance, and high cost performance. It can completely wrap the metal skeleton 2101 and prevent metal oxidation and corrosion. Optionally, the abutment part 23 is made of the same material as the covering layer 2102.

[0074] For example, the elastic element 22 is made of a soft material. Optionally, the elastic element 22 is made of soft TPE (thermoplastic elastomer) or TPV (thermoplastic vulcanizate). The elastic element 22 is an integrated structure that combines sealing, assembly buffering, insertion and extraction force adjustment, and anti-retraction functions. TPE / TPV materials combine the high elasticity, flexibility, and sealing properties of rubber with the easy processing and weather resistance of plastics, making them suitable for complex environments such as high and low temperatures, sun exposure, and rain erosion in automotive outdoor environments. They can precisely adjust the insertion and extraction resistance of the clip 20 during assembly, while utilizing their own elastic deformation to achieve sealing, buffering, and anti-retraction.

[0075] Please see Figure 3 or Figure 7 For example, the main body 21 of the clip has a first buffer portion 217. The first buffer portion 217 is connected to the side of the mounting portion 214 away from the glass 10, and is used to abut against the body sheet metal. The first buffer portion 217 includes, but is not limited to, elastic pillars, elastic blocks, etc. The number of first buffer portions 217 can be one, two or more, and is not limited here. After the clip 20 is installed on the glass 10, during the process of installing it together with the glass 10 to the body, the first buffer portion 217 can play a buffering role when it comes into contact with the body sheet metal to prevent deformation and damage. After assembly, it can improve the clamping force and support strength of the adhesive surface of the tape, prevent the tape from lifting or falling off, and enhance the connection reliability between components.

[0076] Please see Figure 2 or Figure 6Based on any of the aforementioned embodiments, the card strip body 21 is further provided with a second buffer portion 218. The second buffer portion 218 is connected to the bottom of the side of the card strip body 21 facing away from the mounting portion 214. The second buffer portion 218 includes, but is not limited to, buffer posts, buffer rods, buffer protrusions, buffer ribs, or buffer blocks. During product storage and transportation, when the second buffer portion 218 comes into contact with packaging boxes, frames 2101, etc., it can directly transmit the lateral squeezing force to the glass 10 through the bottom of the card strip body 21 and the mounting portion 214, thereby preventing the side of the card strip body 21 facing away from the glass 10 from directly contacting the packaging boxes, frames 2101, etc., which would cause squeezing, scratching, or deformation. This prevents the support plate 212 from being deformed by collision, providing physical protection and ensuring the finished product's appearance and function remain intact upon leaving the factory.

[0077] Among them, after conducting a series of performance tests, including insertion and extraction force test, sealing and waterproof test, high and low temperature weathering test, vibration damping reliability test, and aging durability test, the performance of the card strip 20 in this embodiment meets the requirements in all aspects.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
