Abstract
Description
Technical Field
[0001] This application relates to the field of edge banding for automotive glass, specifically edge banding components, edge banding devices, and vehicles. Background Technology
[0002] A hatchback design with a rear window can improve the car's space utilization. During the hatchback process, there is relative movement between the rear window and the surrounding structural components. Therefore, to ensure smooth relative movement of the rear window, there is usually a relatively large gap between the rear window and the surrounding structural components. To better conceal this gap, a trim strip is typically installed on the rear window. To prevent the trim strip's lip from vibrating and causing abnormal noise, the rear window trim strip usually rests on the surrounding structural components.
[0003] However, the rear windshield edging strip overlaps with the surrounding structural components. When the rear windshield moves relative to the surrounding structural components, the edging strip generates relative friction. This friction can easily cause discoloration or coating peeling of the edging strip, trim, or sheet metal, resulting in appearance defects. It can also cause the lip to bend repeatedly during opening and closing, leading to breakage. Furthermore, it can hinder the normal opening and closing of the rear windshield and easily cause abnormal noises during the lifting process. Summary of the Invention
[0004] In a first aspect, this application provides an edge-binding component, the edge-binding component comprising:
[0005] A first edge-sealing component, the first edge-sealing component being used to cover a portion of the first component to be covered; and
[0006] The second edge-sealing piece is used to cover a portion of the second part to be covered;
[0007] The first edge-binding member can rotate relative to the second edge-binding member so that the edge-binding assembly has a first state and a second state. When the edge-binding assembly is in the first state, the end of the first edge-binding member close to the second edge-binding member elastically abuts against the second edge-binding member and a portion of the first edge-binding member is in an elastically deformed state. When the edge-binding assembly is in the second state, the first edge-binding member and the second edge-binding member disengage from each other.
[0008] Wherein, when the first edge banding piece and the second edge banding piece elastically abut against each other, the elastic abutment point between the first edge banding piece and the second edge banding piece remains unchanged.
[0009] The first edge-binding component includes a first edge-binding body and a lip connected together, wherein the first edge-binding body is used to cover a portion of the first component to be covered;
[0010] The second edge-binding component includes a second edge-binding body and a boss. The second edge-binding body is used to cover a portion of the second part to be covered. The second edge-binding body has a first surface facing the first edge-binding body. The boss protrudes from the first surface and has a second surface that is bent and connected to the first surface.
[0011] When the edging assembly is in the first state, the end of the lip away from the first edging body elastically abuts against the second surface, and the lip has an elastic force toward the second surface. When the edging assembly is in the second state, the lip disengages from the second surface.
[0012] When the edge-binding component is in the first state, the deformation of the lip facing away from the second surface is 1mm to 3mm.
[0013] The lip includes a first end, a main body, and a second end connected in sequence. The first end is connected to the first edging body, and the second end abuts against the second surface in the first state. The main body has an arc-shaped structure, and the arc-shaped structure protrudes in a direction away from the second surface.
[0014] The arc-shaped structure is disposed adjacent to the second end.
[0015] The second surface is curved and protrudes in a direction away from the lip.
[0016] The first edge-binding component further includes a support component, which is at least partially embedded within the first edge-binding body.
[0017] The first edge-binding component further includes a first anti-wear layer, which is disposed on the outer surface of the end of the lip that is away from the first edge-binding body; and / or, the second edge-binding component further includes a second anti-wear layer, which is disposed on the second surface.
[0018] The first edging body and the lip are an integral structure, and the hardness of the first edging body is greater than that of the lip.
[0019] The hardness of the first edging body is HA70°~HA90°, and the hardness of the lip is HA50°~HA60°.
[0020] This application provides an edge-binding assembly that features a first edge-binding member with one end elastically abutting against a second edge-binding member, and at least partially in an elastically deformed state at the end of the first edge-binding member that elastically abuts against the second edge-binding member. This allows the first edge-binding member to rotate relative to the second edge-binding member, and during contact between the two members, the point of contact between the first and second edge-binding members serves as a fulcrum, enabling the elastic deformation of the end of the first edge-binding member that elastically abuts against the second edge-binding member. This prevents displacement of the contact point relative to the second edge-binding member, thereby avoiding sliding friction between the first and second edge-binding members and preventing surface defects caused by frictional damage. It also eliminates noise issues arising from sliding friction between the first and second edge-binding members. Therefore, the edge-binding assembly provided by this application can prevent relative sliding friction between the first and second edge-binding members to avoid frictional damage.
[0021] Secondly, this application also provides an edge-binding device, the edge-binding device comprising:
[0022] The first item to be covered;
[0023] The second item to be covered; and
[0024] As described in the first aspect, the first edge-binding member is used to cover a portion of the first member to be covered, the second edge-binding member is used to cover a portion of the second member to be covered, and the first member to be covered is rotatable relative to the second member to be covered to change the state of the edge-binding assembly.
[0025] When the edge-binding component is in the first state, the surface of the second edge-binding component that abuts against the first edge-binding component is located between two planes where the two surfaces of the first component to be covered are respectively located.
[0026] The edge-binding device provided in this application can prevent relative sliding friction between the first edge-binding member and the second edge-binding member through the edge-binding component structure described in the first aspect, so as to avoid frictional damage.
[0027] Thirdly, this application also provides a vehicle, said vehicle comprising:
[0028] Body of the vehicle; and
[0029] The edge-sealing device as described in the second aspect is installed on the vehicle body.
[0030] The vehicle provided in this application, through the design of the edge-sealing device described in the second aspect, can prevent relative sliding friction between the first edge-sealing component and the second edge-sealing component during the opening and closing of the vehicle's trunk, thereby avoiding frictional damage.

[0048] This application provides an edge-binding component 100. Please refer to... Figures 1-4 , Figure 1 A schematic diagram of the edge-binding component in a first state according to an embodiment of this application; Figure 2 for Figure 1A schematic diagram illustrating the process of the middle edge component transitioning from the first state to the second state; Figure 3 for Figure 1 A schematic diagram of the middle edge-wrapping component in its second state; Figure 4 This is a schematic diagram of the edge-binding assembly in a first state according to another embodiment of this application. In this embodiment, the edge-binding assembly 100 includes a first edge-binding member 110 and a second edge-binding member 120. The first edge-binding member 110 is used to cover a portion of a first part to be covered 200. The second edge-binding member 120 is used to cover a portion of a second part to be covered 300. The first edge-binding member 110 is rotatable relative to the second edge-binding member 120 so that the edge-binding assembly 100 has a first state and a second state. When the edge-binding assembly 100 is in the first state, the end of the first edge-binding member 110 near the second edge-binding member 120 elastically abuts against the second edge-binding member 120, and a portion of the first edge-binding member 110 is in an elastically deformed state. When the edge-binding assembly 100 is in the second state, the first edge-binding member 110 and the second edge-binding member 120 are no longer in contact. Wherein, when the first edge banding 110 and the second edge banding 120 elastically abut against each other, the elastic abutment point between the first edge banding 110 and the second edge banding 120 remains unchanged.
[0049] In this embodiment, the edge-sealing assembly 100 is applied to vehicle 1 (see below). Figure 11 and Figure 12 Specifically, the edge-sealing assembly 100 is applied to a hatchback vehicle 1, and is installed at the opening and closing point of the trunk and sunroof, or at the opening and closing point of the trunk and other vehicle body structures. In this embodiment, the edge-sealing assembly 100 is illustrated using a hatchback vehicle 1. It is understood that in other embodiments, the edge-sealing assembly 100 can be applied to any structure that requires rotation to achieve an open / closed state transition, such as the front trunk, or windows that rotate via push-pull mechanisms.
[0050] In this embodiment, the first component to be covered 200 is the rear windshield, and the second component to be covered 300 is the sunroof glass (see [link]). Figure 1 ), or the second component to be covered 300 is a metal sheet metal structure or a plastic decorative panel structure (see [link]). Figure 4When the second part to be covered 300 is a metal sheet structure or a plastic trim structure, the second part to be covered 300 and the second edge-wrapping part 120 can be an integral peripheral structural component. The edge-wrapping assembly 100 has a first state and a second state. When the edge-wrapping assembly 100 is in the first state, that is, when the trunk of the hatchback vehicle 1 is closed, the end of the first edge-wrapping part 110 near the second edge-wrapping part 120 elastically abuts against the second edge-wrapping part 120, and a portion of the first edge-wrapping part 110 is in an elastic deformation state. The cooperation between the first edge-wrapping part 110 and the second edge-wrapping part 120 can seal the gap between the first part to be covered 200 and the second part to be covered 300, and the elastic abutment between the first edge-wrapping part 110 and the second edge-wrapping part 120 improves the sealing performance. The force of the abutment between the first edge-wrapping part 110 and the second edge-wrapping part 120 is also called the overlap force. The combination of the second part to be covered 300 and the second edge-wrapping part 120 is also called the edge-wrapping strip structure, which is a peripheral structural part.
[0051] According to such Figures 1-3 As shown by the arrow, the first edge-wrapping member 110 can be rotated to allow the edge-wrapping assembly 100 to switch to the second state. When the edge-wrapping assembly 100 is in the second state, i.e., when the trunk of the hatchback vehicle 1 is open, the first edge-wrapping member 110 and the second edge-wrapping member 120 are no longer in contact. It should be noted that the rotation center of the first edge-wrapping member 110 relative to the second edge-wrapping member 120 is the rotational connection point between the trunk and the body of the hatchback vehicle 1, not the point of contact between the first edge-wrapping member 110 and the second edge-wrapping member 120. Furthermore, when the edge-wrapping assembly 100 is in the second state, the angle between the first piece to be wrapped 200 and the second piece to be wrapped 300 can be any angle, as long as the first edge-wrapping member 110 and the second edge-wrapping member 120 are no longer in contact.
[0052] During the transition of the edging assembly 100 from the first state to the second state, before the first edging member 110 and the second edging member 120 disengage, the elastic deformation force of the portion of the first edging member 110 in an elastic deformation state gradually decreases. That is, the first edging member 110 achieves an overall positional change through elastic deformation recovery. Specifically, taking the contact point between the first edging member 110 and the second edging member 120 as a fulcrum, the end of the first edging member 110 that abuts against the second edging member 120 undergoes elastic recovery in the direction of rotation of the first edging member 110 relative to the second edging member 120. Based on the interaction of forces, the elastic recovery force of the end of the first edging member 110 that abuts against the second edging member 120 acts on the surface of the second edging member 120 that abuts against the first edging member 110, preventing the first edging member 110 from contacting the second edging member 120. The abutment points of the second edge banding 120 are positioned relative to each other, and the elastic recovery of the end of the first edge banding 110 that abuts against the second edge banding 120 enables relative movement of the portion of the first edge banding 110 other than the abutment points of the first edge banding 110 and the second edge banding 120. This allows the abutment points of the first edge banding 110 and the second edge banding 120 to rotate relative to the second edge banding 120 without displacement relative to the second edge banding 120, thereby avoiding sliding friction between the first edge banding 110 and the second edge banding 120 and preventing appearance defects caused by friction damage. At the same time, it eliminates the noise problem caused by sliding friction between the first edge banding 110 and the second edge banding 120.
[0053] During the transition of the edge-binding assembly 100 from the second state to the first state, after the first edge-binding member 110 and the second edge-binding member 120 abut against each other, the abutting point of the first edge-binding member 110 and the second edge-binding member 120 takes the abutting point as the fulcrum, and the abutting end of the first edge-binding member 110 and the second edge-binding member 120 undergoes elastic deformation. The force of the elastic deformation acts on the abutting point of the first edge-binding member 110 and the second edge-binding member 120 as the fulcrum, thereby preventing the abutting point of the first edge-binding member 110 and the second edge-binding member 120 from displacing relative to the second edge-binding member 120. This prevents the first edge-binding member 110 and the second edge-binding member 120 from sliding friction, thereby preventing the first edge-binding member 110 and the second edge-binding member 120 from suffering appearance friction damage and causing appearance defects. At the same time, it eliminates the noise problem caused by the sliding friction between the first edge-binding member 110 and the second edge-binding member 120.
[0054] In other words, during the opening and closing of the trunk of the hatchback vehicle 1, the first edge piece 110 and the second edge piece 120 can prevent relative sliding friction between them, thereby avoiding problems such as appearance defects and abnormal noises.
[0055] During the transition between the first and second states of the edge-binding component 100, the second piece to be covered 300 remains stationary, and the overlapping force generated by the elastic contact between the first edge-binding component 110 and the second edge-binding component 120 always remains in one direction.
[0056] In summary, this application provides an edge-binding assembly 100 by setting one end of a first edge-binding member 110 to elastically abut against a second edge-binding member 120, with at least a portion of the end of the first edge-binding member 110 elastically abutting against the second edge-binding member 120 in an elastically deformed state. This allows the first edge-binding member 110 to rotate relative to the second edge-binding member 120, and during the contact between the first edge-binding member 110 and the second edge-binding member 120, using the contact point between the first edge-binding member 110 and the second edge-binding member 120 as a fulcrum. The end of the first edge banding member 110 that elastically abuts against the second edge banding member 120 undergoes elastic deformation to prevent displacement of the contact point between the first edge banding member 110 and the second edge banding member 120 relative to the second edge banding member 120. This avoids sliding friction between the first edge banding member 110 and the second edge banding member 120, thereby preventing surface damage caused by friction and eliminating noise issues arising from sliding friction between them. Therefore, the edge banding assembly 100 provided in this application can prevent relative sliding friction between the first edge banding member 110 and the second edge banding member 120 to avoid friction damage.
[0057] Please refer to Figures 1-5 , Figure 5 for Figure 1The diagram shows a partially enlarged view of one embodiment. In this embodiment, the first edge-binding member 110 includes a first edge-binding body 111 and a lip 112 connected together. The first edge-binding body 111 is used to cover a portion of the first part to be covered 200. The second edge-binding member 120 includes a second edge-binding body 121 and a boss 122. The second edge-binding body 121 is used to cover a portion of the second part to be covered 300, and the second edge-binding body 121 has a first surface 1211 facing the first surface 1211. The boss 122 protrudes from the first surface 1211, and the boss 122 has a second surface 1221 that is bent and connected to the first surface 1211. When the edge-binding assembly 100 is in the first state, the end of the lip 112 facing away from the first edge-binding body 111 elastically abuts against the second surface 1221, and the lip 112 has an elastic force towards the second surface 1221. When the edge-binding assembly 100 is in the second state, the lip 112 is no longer in contact with the second surface 1221.
[0058] In this embodiment, when the edge-binding assembly 100 is in the first state, the end of the lip 112 facing away from the first edge-binding body 111 elastically abuts against the second surface 1221 and has an elastic force toward the second surface 1221. Therefore, during the process of the edge-binding assembly 100 changing from the first state to the second state, before the first edge-binding member 110 and the second edge-binding member 120 disengage, the lip 112, due to its elastic force toward the boss 122 toward the second surface 1221, can prevent the contact point of the lip 112 elastically abutting against the second surface 1221 from displacing relative to the second surface 1221, thereby avoiding the generation of sliding friction. In this process, the rotation amount generated by the elastic deformation recovery of the lip 112 balances the rotation distance of the other end of the lip 112 facing away from the second surface 1221 and the first edge-binding body 111 relative to the second edge-binding member 120, further preventing sliding friction between the lip 112 and the second surface 1221. Furthermore, during the transition of the edge-binding assembly 100 from the second state to the second state, after the first edge-binding member 110 and the second edge-binding member 120 begin to contact, the lip 112 abuts against the second surface 1221. With the contact point between the lip 112 and the second surface 1221 as the fulcrum, the lip 112 undergoes elastic deformation and generates an elastic force toward the second surface 1221 to prevent the contact point between the lip 112 and the second surface 1221 from displacing relative to the second surface 1221, thereby avoiding sliding friction between the lip 112 and the second surface 1221. In this process, the rotation amount generated by the elastic deformation of the lip 112 balances the rotation distance of the other end of the lip 112 away from the second surface 1221 and the first edge-binding body 111 relative to the second edge-binding member 120, further preventing sliding friction between the lip 112 and the second surface 1221.
[0059] Optionally, the number of the bosses 122 is one or more, the number of the lips 112 is one or more, and one lip 112 overlaps with one or more of the bosses 122.
[0060] Optionally, the second surface 1221 is curved and protrudes in a direction away from the lip 112, i.e., the second surface 1221 is a concave curved surface, which can further prevent the end of the lip 112 that abuts against the second surface 1221 from displacing relative to the second surface 1221. Furthermore, the lip 112 abuts against the most concave point of the second surface 1221, so that the portion of the second surface 1221 located near the most concave point can limit the end of the lip 112 that abuts against the second surface 1221, further preventing the abutment point of the lip 112 against the second surface 1221 from displacing relative to the second surface 1221.
[0061] Optionally, the first edging member 110 further includes a support member 113, which is at least partially embedded in the first edging body 111, so that the support member 113 can support the first edging body 111 and reduce the thermal expansion and contraction rate of the first edging body 111. For example, the support member 113 can be, but is not limited to, aluminum strip, copper wire, glass fiber, etc.
[0062] Optionally, the first edging body 111 and the lip 112 are an integral structure, and the hardness of the first edging body 111 is greater than the hardness of the lip 112. The integral structure of the first edging body 111 and the lip 112 improves the overall stability of the first edging component 110. The first edging body 111 provides the main support, and the lower hardness of the lip 112 facilitates elastic deformation. Specifically, the hardness of the first edging body 111 is HA70°~HA90°, and the hardness of the lip 112 is HA50°~HA60°.
[0063] Optionally, the first edge-binding body 111 and the lip edge 112 are joined together by extrusion or by integral injection molding.
[0064] Optionally, the material of the first edging body 111 can be, but is not limited to, thermoplastic elastomer (TPE), ethylene propylene diene monomer (EPDM), polyvinyl chloride (PVC), etc. Preferably, the material of the first edging body 111 is TPE or EPDM to improve the weather resistance and fatigue resistance of the first edging body 111.
[0065] Optionally, the material of the lip 112 may be the same as or different from the material of the first edging body 111. When the lip 112 and the first edging body 111 are made of the same material, the material of the lip 112 is TPE or EPDM.
[0066] Optionally, the material of the lip 112 has a density of 0.6 g / cm³. 3 -0.9g / cm 3 The use of foamed EPDM or TPE with a hardness of HA50°~HA60° facilitates the overlap between the lip 112 and the boss 122.
[0067] Please refer to Figure 1 , Figure 5 and Figure 6 , Figure 6 for Figure 5 A schematic diagram of the deformation of the lip edge when the binding assembly is in the first state. In this embodiment, when the binding assembly 100 is in the first state, the deformation of the lip edge 112 in the direction away from the second surface 1221 is shown in the diagram. Figure 6In this case, D) is 1mm to 3mm, so that during the transition between the first and second states of the edge-binding assembly 100, when the lip 112 abuts against the second surface 1221, the elastic force generated by the deformation of the lip 112 towards the second surface 1221 can prevent the contact point between the lip 112 and the second surface 1221 from displacing relative to the second surface 1221, thereby avoiding sliding friction between the lip 112 and the second surface 1221. For example, when the edge-binding assembly 100 is in the first state, the deformation of the lip 112 in the direction away from the second surface 1221 can be, but is not limited to, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, or other values between 1mm and 3mm. If the edge-binding assembly 100 is in the first state, and the deformation of the lip 112 in the direction away from the second surface 1221 is less than 1 mm, then the elastic force generated by the lip 112 in the direction towards the second surface 1221 through elastic deformation is too small, which can easily cause the lip 112 to slide relative to the second surface 1221 during the transition between the first and second states of the edge-binding assembly 100. If the edge-binding assembly 100 is in the first state, and the deformation of the lip 112 in the direction away from the second surface 1221 is greater than 3 mm, then the excessive elastic force due to the deformation of the lip 112 exceeding 3 mm makes it difficult to assemble the edge-binding assembly 100 into the first state, which is not conducive to installation. Therefore, in this embodiment, when the edge-binding assembly 100 is in the first state, the deformation of the lip 112 in the direction away from the second surface 1221 is 1mm to 3mm. This allows for relative sliding friction between the lip 112 and the second surface 1221 during the transition between the first and second states of the edge-binding assembly 100, and also facilitates the assembly of the edge-binding assembly 100. The elastic contact between the lip 112 and the second surface 1221 in the first state is also referred to as interference overlap.
[0068] Please refer to Figure 5 and Figure 7 , Figure 7 for Figure 5 A schematic diagram of the structure of the middle lip. In this embodiment, the lip 112 includes a first end 1121, a main body 1122, and a second end 1123 connected in sequence. The first end 1121 is connected to the first edging body 111, and the second end 1123 abuts against the second surface 1221 in the first state. The main body 1122 has an arc-shaped structure, and the arc-shaped structure protrudes in a direction away from the second surface 1221.
[0069] In this embodiment, the arc-shaped structure helps to reduce the contact area between the second end 1123 of the lip 112 and the second surface 1221, thereby preventing sliding friction due to excessive contact area between the second end 1123 and the second surface 1221, and also helps to improve the stability of the lip 112 during the rotation of the first edge piece 110 relative to the second edge piece 120. Furthermore, the arc-shaped structure facilitates elastic deformation of the lip 112, thereby helping to balance the amount of rotation of the first edge piece 110 relative to the second edge piece 120 when the second end 1123 abuts against the second surface 1221.
[0070] Furthermore, the arc-shaped structure is positioned adjacent to the second end 1123, which is beneficial in the first state, where the portion of the lip 112 adjacent to the second end 1123 is positioned at a certain angle with the second surface 1221, thereby facilitating the elastic contact of the lip 112 with the second surface 1221 and improving the stability of the contact between the first edge-sealing member 110 and the second edge-sealing member 120.
[0071] Please refer to Figure 8 , Figure 8 for Figure 1 The diagram shows a partially enlarged view of part I in another embodiment. In this embodiment, the first edging member 110 further includes a first anti-wear layer 114, which is disposed on the outer surface of the end of the lip 112 opposite to the first edging body 111. And / or, the second edging member 120 further includes a second anti-wear layer 123, which is disposed on the second surface 1221.
[0072] In this embodiment, the first anti-wear layer 114 and the second anti-wear layer 123 can reduce the wear generated when the lip 112 comes into contact with the second surface 1221, thereby protecting the lip 112 and the second surface 1221. For example, the first anti-wear layer 114 can be, but is not limited to, flocking, spray paint, etc. The second anti-wear layer 123 can be, but is not limited to, flocking, spray paint, etc.
[0073] This application also provides an edging device 10. Please refer to... Figure 9 and Figure 10 , Figure 9 A schematic diagram of the edge-binding device provided in one embodiment of this application, with the edge-binding assembly in a first state; Figure 10 for Figure 9A schematic diagram of the edge-binding device in the second state of the edge-binding assembly. In this embodiment, the edge-binding device 10 includes a first piece to be bound 200, a second piece to be bound 300, and an edge-binding assembly 100 as described in any of the foregoing embodiments. The first edge-binding piece 110 is used to bind a portion of the first piece to be bound 200. The second edge-binding piece 120 is used to bind a portion of the second piece to be bound 300, and the first piece to be bound 200 is rotatable relative to the second piece to be bound 300 to change the state of the edge-binding assembly 100.
[0074] In this embodiment, the edging device 10 is configured such that one end of the first edging member 110 elastically abuts against the second edging member 120, and at least part of the end of the first edging member 110 that elastically abuts against the second edging member 120 is in an elastically deformed state. This allows the first edging member 110 to rotate relative to the second edging member 120, and during the contact between the first edging member 110 and the second edging member 120, the contact point between the first edging member 110 and the second edging member 120 serves as a fulcrum. The end of the first edge banding member 110 that elastically abuts against the second edge banding member 120 undergoes elastic deformation to prevent displacement of the contact point between the first edge banding member 110 and the second edge banding member 120 relative to the second edge banding member 120. This avoids sliding friction between the first edge banding member 110 and the second edge banding member 120, thereby preventing surface damage and defects caused by friction. It also eliminates noise issues arising from sliding friction between the first edge banding member 110 and the second edge banding member 120. Therefore, the edge banding device 10 provided in this application can prevent relative sliding friction between the first edge banding member 110 and the second edge banding member 120 to avoid friction damage.
[0075] Optionally, when the edge-binding assembly 100 is in the first state, the surfaces of the second edge-binding member 120 and the first edge-binding member 110 that abut against each other are located between the planes of the two opposing surfaces of the first piece to be covered 200. In this embodiment, when the edge-binding assembly 100 is in the first state, the outer surface of the first piece to be covered 200 is the surface located outside the vehicle when the edge-binding device 10 is installed in the vehicle 1, and the inner surface of the piece to be covered is the surface located inside the vehicle when the edge-binding device 10 is installed in the vehicle 1. When the edge-binding assembly 100 is in the first state, the surfaces of the second edge-binding member 120 and the first edge-binding member 110 that abut against each other are lower than the outer surface of the first piece to be covered 200, which helps to conceal the overlap between the second edge-binding member 120 and the first edge-binding member 110, thereby improving the overall aesthetic appearance. When the edge-wrapping assembly 100 is in the first state, the surface of the second edge-wrapping member 120 that abuts against the first edge-wrapping member 110 is higher than the inner surface of the first part to be wrapped 200, which helps to prevent the edge-wrapping device 10 from generating wind noise during the driving process of the vehicle 1 when it is installed on the vehicle 1.
[0076] This application also provides vehicle 1. Please refer to... Figure 11 and Figure 12 , Figure 11 A schematic diagram of the vehicle in a first state when the edging assembly is provided according to an embodiment of this application; Figure 12 for Figure 11 A schematic diagram of the vehicle's structure with the edge-sealing assembly in a second state. In this embodiment, the vehicle 1 includes a body body 20 and an edge-sealing device 10 as described in any of the foregoing embodiments, the edge-sealing device 10 being mounted on the body body 20.
[0077] In this embodiment, the vehicle 1 is a hatchback vehicle 1. The vehicle 1 is connected to a second edge-binding member 120 via one end of a first edge-binding member 110 in the edge-binding device 10, and at least part of the end of the first edge-binding member 110 that elastically abuts against the second edge-binding member 120 is in an elastically deformed state. This allows the first edge-binding member 110 to rotate relative to the second edge-binding member 120, and during the contact between the first edge-binding member 110 and the second edge-binding member 120, with the contact point between the first edge-binding member 110 and the second edge-binding member 120 serving as a fulcrum. The first edge-binding member 110 elastically abuts against the second edge-binding member 120 at one end, causing elastic deformation to prevent displacement of the contact point between the first edge-binding member 110 and the second edge-binding member 120 relative to the second edge-binding member 120. This avoids sliding friction between the first edge-binding member 110 and the second edge-binding member 120, thereby preventing surface damage and defects caused by friction. It also eliminates noise issues caused by sliding friction between the first edge-binding member 110 and the second edge-binding member 120. Therefore, the vehicle 1 provided in this application can prevent relative sliding friction between the first edge-binding member 110 and the second edge-binding member 120 during the opening and closing of the vehicle 1's trunk, thus avoiding friction damage.
