Abstract
Description
Technical Field
[0001] This application belongs to the field of automotive parts technology, and more specifically, relates to a door and window frame bright strip mounting structure, a door assembly, and a vehicle. Background Technology
[0002] Currently, when adding a bright strip to the corner window of a car door, the side closest to the window glass is usually fixed to the door sheet metal, while the other side extends to the door seal and engages with it; that is, the connection point between the bright strip and the door sheet metal is located inside the bright strip's sealing ring. This connection method results in an excessively long cantilever in the width direction of the bright strip. After the door seal is installed, the cantilever end of the bright strip is pushed up, and the edge of the bright strip protrudes outward, creating a surface difference with the side window surface. This surface difference may cause the seal to fail, increasing the risk of water and air leaks; and during vehicle operation, the bright strip, due to the surface difference, generates noise when impacted by airflow, reducing the comfort of passengers inside the vehicle. Utility Model Content
[0003] The purpose of this application is to provide a door and window frame bright strip installation structure, door assembly and vehicle, which aims to solve the problems of excessively long cantilever of the bright strip and surface difference between the bright strip and the side window.
[0004] To achieve the above objectives, in a first aspect, embodiments of this application provide a door window frame bright strip mounting structure, comprising:
[0005] Door sheet metal work;
[0006] Bright strip assembly, located on the outer side of the door sheet metal;
[0007] A locking assembly connects the bright strip assembly and the door sheet metal. There are at least two sets of locking assemblies, and adjacent sets of locking assemblies are spaced apart along the width direction of the bright strip assembly.
[0008] Compared with existing technologies, by arranging multiple sets of locking components between the bright strip assembly and the door sheet metal, and with these multiple sets of locking components spaced apart along the width direction of the bright strip assembly, multiple mounting points are formed between the bright strip assembly and the door sheet metal along the width direction of the bright strip. In terms of coverage, this application increases the coverage of the mounting points in the width direction of the bright strip assembly by changing the position of the mounting points, and reduces the cantilever length of the bright strip assembly. In terms of quantity, by setting multiple sets of locking components, the number of mounting points is increased, and the connection strength is improved. In terms of deformability, the arrangement of multiple sets of locking components suppresses the deformability range of the bright strip assembly in its thickness direction.
[0009] The solution shown in this application reduces the length of the cantilever by changing the arrangement of multiple locking components; it increases the support strength of the mounting point for the cantilever of the bright strip component, so that the limiting force on the edge of the cantilever offsets the tension of the sealing strip, avoiding surface differences between the bright strip component and the door after installation; the multiple locking components increase the number and strength of the binding points on the bright strip component, improving the installation stability of the bright strip component; the deformation in the thickness direction of the bright strip component is reduced, and the gap between the edge of the bright strip component away from the window opening and the door sheet metal is reduced; the lip of the door sealing strip deforms more under the compression of the bright strip component, enhancing the sealing performance.
[0010] In conjunction with the first aspect, one possible implementation also includes:
[0011] A sealing ring is located between the bright strip assembly and the door sheet metal;
[0012] At least one set of the locking components is located on the side of the sealing ring closer to the window opening, and at least one set of the locking components is located on the side of the sealing ring away from the window opening.
[0013] In the above technical solution, the installation points of the bright strip assembly and the door sheet metal are divided into two parts by the distribution of multiple sets of locking components. One part is located on the side of the sealing ring near the window opening, retaining the traditional installation point position; the other part is located on the side of the sealing ring away from the window opening, serving as a new installation point to improve the connection strength of the cantilever side of the bright strip assembly. The new installation point is close to the cantilever side of the bright strip assembly to shorten the cantilever length, thereby reducing the surface difference between the cantilever and the door. Furthermore, the locking components on both sides of the sealing ring can confine the sealing ring between the bright strip assembly and the door sheet metal, ensuring uniform force on the sealing ring and improving the sealing effect.
[0014] In some embodiments, the bright bar component includes:
[0015] Bright strip body;
[0016] A frame is disposed on the inner side of the bright strip body, and the frame faces the door sheet metal;
[0017] The fixed end of the locking component is fixedly connected to the frame, and the free end of the locking component engages with the mounting hole on the door sheet metal.
[0018] In the above technical solution, a skeleton is added to the inside of the bright strip body to improve the support strength of the bright strip body and keep the bright strip body under uniform force; the skeleton serves as a support structure and is connected to the fixed end of the locking component. When installing the skeleton and the bright strip body, you only need to align the free end of the locking component inside the skeleton with the mounting hole of the door sheet metal and press it down, which is convenient for installation.
[0019] In some embodiments, each group of locking components includes multiple locking elements, and the multiple locking elements of the same group of locking components are spaced apart along the length direction of the skeleton;
[0020] The locking element includes:
[0021] A snap-fit seat, which is fixedly connected to the frame;
[0022] The buckle body is connected to the buckle seat, and the free end of the buckle body has a snap-fit part that snaps into the mounting hole on the door sheet metal.
[0023] In the above technical solution, the buckle body is connected to the frame by the buckle seat, which is convenient to process and has high connection strength; and multiple locking parts are arranged at intervals along the length of the frame to form a set of locking components, realizing multi-point installation in the length of the frame; through multi-point snap-fit, a stable connection between the frame and the door sheet metal is achieved.
[0024] In some embodiments, the latching seat includes:
[0025] Support portion, which is connected to the frame.
[0026] A deformable part is connected to the side of the support part away from the frame. The cross-sectional area of the deformable part gradually increases in the direction away from the support part. The deformable part is used to fit onto the door sheet metal.
[0027] The buckle body is connected to the support portion, and the free end of the buckle body passes through the deformable portion to connect to the mounting hole.
[0028] In the above technical solution, the buckle seat is divided into two parts. The support part is directly connected to the frame as the bottom structure. The support part has a receiving cavity inside, and the base of the buckle body is fixed in the receiving cavity. Since the deformable part is frustoconical, its support strength gradually decreases from the middle to the outer edge, ensuring that the support force is stronger closer to the mounting hole, and forming a transitional support effect around the mounting hole of the door sheet metal, so as to avoid deformation of the door sheet metal due to excessive force on the mounting hole.
[0029] In some embodiments, the bright strip body and the skeleton are connected by a fastener; the fastener includes:
[0030] A connecting part, which is connected to the inner side of the bright strip body;
[0031] The bending portion is connected to the connecting portion, and the bending portion passes through the positioning hole of the skeleton and presses the skeleton into the inner side of the bright strip body.
[0032] In the above technical solution, the clip connects the bright strip body and the skeleton, replacing the original adhesive connection method with a snap-fit connection, which improves the connection strength; the bending part adheres the skeleton to the bright strip body by bending itself, which increases the rigidity of the bright strip assembly and reduces its deformation under stress.
[0033] In some embodiments, multiple sets of the card are provided, with adjacent sets of the card spaced apart along the width direction of the bright strip body.
[0034] In the above technical solution, relying on the distribution of the clips, a uniformly distributed multi-point snap-fit fixing structure is formed between the skeleton and the bright strip body, which improves the connection strength between the skeleton and the bright strip body and the uniformity of the stress on the bright strip body.
[0035] In conjunction with the first aspect, one possible implementation also includes:
[0036] A door sealing strip is provided around the edge of the door sheet metal, and the edge of the bright strip assembly engages with the lip of the door sealing strip.
[0037] In the above technical solution, the side of the door sealing strip near the bright strip assembly has several outwardly protruding lips. The bright strip assembly fits into the lips and is snapped and covered by the lips to prevent its edges from being exposed. The door sealing strip and the sealing ring form a double sealing structure to improve sealing performance.
[0038] Secondly, this application also provides a door assembly that adopts the above-mentioned door window frame bright strip mounting structure.
[0039] The above technical solution adopts the above-mentioned door and window frame bright strip installation structure. The bright strip assembly is fixed to the door using the above installation structure, which improves the connection strength of the bright strip assembly and avoids surface difference between the bright strip assembly and the door; thus improving the sealing performance of the door.
[0040] Thirdly, this application also provides a vehicle that adopts the above-mentioned door and window frame bright strip installation structure.
[0041] The above technical solution adopts the aforementioned door and window frame bright strip installation structure. The bright strip assembly is fixed to the door using the above installation structure, which improves the connection strength of the bright strip assembly and avoids surface differences between the bright strip assembly and the door; improves the sealing performance of the door; reduces the impact of airflow on the bright strip during driving, reduces noise, and improves the comfort of passengers inside the vehicle.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a few" means two or more, unless otherwise explicitly specified.
[0057] Please refer to the following: Figures 1 to 10 This application describes the door and window frame bright strip mounting structure, door assembly, and vehicle provided. The door and window frame bright strip mounting structure includes a door sheet metal 7, a bright strip assembly, and a locking assembly. The bright strip assembly is located on the outer side of the door sheet metal 7. The locking assembly connects the bright strip assembly and the door sheet metal 7, and there are at least two sets of locking assemblies, with adjacent sets spaced apart along the width direction of the bright strip assembly. The outer side of the door sheet metal 7 refers to the side of the door sheet metal 7 facing outwards from the driver's side.
[0058] The bright strip assembly covers the outer side of the door sheet metal 7 along the edge of the door window frame; the length direction of the bright strip assembly is along the edge of the window opening, and the width direction of the bright strip assembly is perpendicular to the edge of the window opening.
[0059] During installation, the locking components can be connection structures such as bolts or snap-fit connectors. By arranging multiple sets of locking components between the bright strip assembly and the door sheet metal 7, with these sets spaced apart along the width direction of the bright strip assembly, multiple mounting points are formed between the bright strip assembly and the door sheet metal 7 along the width direction of the bright strip.
[0060] The door and window frame bright strip mounting structure provided in this application has the following advantages compared with the prior art:
[0061] (1) The mounting point of the traditional bright strip assembly is located on the side of the frame 2 near the window opening, which results in the cantilever 44 of the bright strip assembly being too long in the width direction. The limiting force of the mounting point on the side of the bright strip assembly away from the window opening is small and cannot offset the tension of the door sealing strip 6. In this embodiment, the position of the mounting point is changed to increase the width range of the bright strip assembly covered by the mounting point, thereby reducing the length of the cantilever 44; the support strength of the mounting point for the cantilever 44 of the bright strip assembly is increased, so that the limiting force on the edge of the cantilever 44 offsets the tension of the sealing strip and avoids the surface difference between the bright strip assembly and the door after installation.
[0062] (2) Traditional bright strip components only have one set of mounting points near the window opening, which is relatively few. In this embodiment, by setting multiple sets of locking components, the number of mounting points is increased, thereby increasing the binding strength of the locking components on the bright strip components and improving the installation stability.
[0063] (3) The edge of the traditional bright strip assembly is pushed up by the door sealing strip 6, which affects the lip sealing effect of the door sealing strip 6 and the sealing performance between the bright strip assembly and the door sheet metal 7. In this embodiment, multiple sets of locking components are applied to the bright strip assembly, which reduces the deformation of the bright strip assembly in the thickness direction and reduces the gap between the edge of the bright strip assembly away from the window opening and the door sheet metal 7; the lip of the door sealing strip 6 deforms more under the squeezing action of the bright strip assembly, thus enhancing the sealing performance.
[0064] In some embodiments, the locking assembly described above may be a bolt or a snap-fit.
[0065] When the locking assembly is a bolt, a nut is fixedly installed on the inner wall of the bright strip assembly. When the bright strip assembly is pressed against the door sheet metal 7, the bolt is then passed through the mounting hole of the door sheet metal 7 and connected to the nut on the inner side of the bright strip assembly. A rubber washer is fitted on the bolt, and the rubber washer is pressed against the inner side of the door sheet metal 7 by the nut.
[0066] When the locking assembly is a snap-fit component, the snap-fit structure includes a snap-fit part and a locking buckle. The snap-fit part and the locking part are installed opposite each other, for example, the snap-fit part is installed on the inside of the bright trim assembly, and the locking part is installed on the outside of the door sheet metal 7; or vice versa, the snap-fit part is installed on the outside of the door sheet metal 7, and the locking part is installed on the inside of the bright trim assembly. Both the snap-fit part and the locking part can be installed using rubber injection molding. During installation, the snap-fit part and the locking part are engaged symmetrically.
[0067] In some embodiments, such as Figures 2 to 5 As shown, the door window frame bright strip mounting structure also includes a sealing ring 8, which is located between the bright strip assembly and the door sheet metal 7; at least one set of locking components is located on the side of the sealing ring 8 near the window opening, and at least one set of locking components is located on the side of the sealing ring 8 away from the window opening.
[0068] The sealing ring 8 is located in the gap between the bright strip assembly and the door sheet metal 7 to seal the gap and prevent rainwater, car wash water and other liquids from seeping into the car from the edge of the window. The elastic cushioning effect of the sealing ring 8 can reduce the friction between the door sheet metal 7 and the bright strip assembly and avoid wear on the parts. In addition, the sealing ring 8 can help fix the position of the bright strip assembly, ensure that the gap between the bright strip assembly and the door sheet metal 7 is uniform, and avoid surface differences between the outer surface of the bright strip assembly and the outer surface of the door.
[0069] The sealing ring 8 can be made of materials such as silicone rubber, EPDM rubber, or thermoplastic elastomer. Located on the outer side of the window glass lift track, the sealing ring 8 maintains a certain distance from the glass edge. Its main function is to seal the gap between the sheet metal and the bright strip, rather than directly contacting the glass. Optionally, the interference between the sealing ring 8 and the window frame is 1mm, and the sealing ring 8 is pressed onto the door sheet metal 7 by the bright strip assembly. The sealing ring 8 can be injection molded onto the bright strip or onto the door sheet metal 7.
[0070] Traditionally, the mounting point of the bright trim component and the door sheet metal 7 is located on the side of the sealing ring 8 near the window opening. In this embodiment, the mounting point of the bright trim component and the door sheet metal 7 is divided into two parts. One part is located on the side of the sealing ring 8 near the window opening, retaining the traditional mounting point position; the other part is located on the side of the sealing ring 8 away from the window opening, serving as a new mounting point to improve the connection strength of the cantilever 44 side of the bright trim component.
[0071] like Figure 2 As shown, the locking assembly has two sets, one set located on the side of the sealing ring 8 near the window opening, and the other set located on the side of the sealing ring 8 away from the window opening.
[0072] During actual installation, the number of locking components can be selected according to the actual width of the bright strip assembly. For example, when the bright strip assembly is wide, two or three sets of locking components can be set on the outside of the sealing ring 8, and adjacent sets of locking components on the outside of the sealing ring 8 are spaced apart along the width direction of the bright strip assembly.
[0073] Each locking assembly may have multiple locking elements. The line connecting multiple locking elements in the same group is consistent with the length direction of the frame 2, and the multiple locking elements in the same group are equally spaced. Locking elements in different groups are staggered along the length direction of the frame 2.
[0074] While maintaining the traditional connection method, a locking component is added to the side of the sealing ring 8 away from the window opening. This can shorten the length of the cantilever 44 of the bright strip component, increase the binding strength of the edge of the bright strip component, improve the flatness of the outer surface of the bright strip component, and reduce surface differences. The locking components on both sides of the sealing ring 8 can also limit the sealing ring 8 between the bright strip component and the door sheet metal 7, ensuring that the sealing ring 8 is subjected to uniform force and improving the sealing effect.
[0075] The sealing ring 8 works in conjunction with the door sealing strip 6 on the outer edge of the door to form a double seal between the bright strip assembly and the door sheet metal 7, ensuring a good sealing effect.
[0076] like Figure 2 As shown, the locking assembly includes a first locking assembly 4 and a second locking assembly 5. The first locking assembly 4 is located on the side of the sealing ring 8 closer to the window opening, and the second locking assembly 5 is located on the side of the sealing ring 8 away from the window opening. The first locking assembly 4 and the second locking assembly 5 have identical structures, and their dimensions can be adjusted according to actual needs. Figures 6 to 8 As can be seen, the first locking component 4 and the second locking component 5 have the same structure, but differ in shape and size.
[0077] In some embodiments, the above-mentioned bright bar component may adopt the following... Figures 3 to 5 The structure is shown. The bright strip assembly includes a bright strip body 1 and a frame 2; the frame 2 is located inside the bright strip body 1 and faces the door sheet metal 7; the fixed end of the locking assembly is fixedly connected to the frame 2, and the free end of the locking assembly engages with the mounting hole on the door sheet metal 7.
[0078] The bright strip body 1 and the frame 2 are connected by adhesive and / or snap-fit. The circumferential edges of the bright strip body 1 are all bent, and the frame 2 is fitted to the inner wall of the bright strip body 1 and limited by the bends at the edges of the bright strip body 1. The outer wall of the frame 2 is glued to the inner wall of the bright strip body 1, thus achieving the connection between the frame 2 and the bright strip body 1.
[0079] During installation, the frame 2 serves as the supporting structure for the bright strip body 1, and the frame 2 is connected to the door sheet metal 7.
[0080] The locking assembly uses snap-fit connectors. To improve installation strength and ease of installation, the fixed end of the snap-fit connector is connected to the frame 2, and the moving end of the snap-fit connector is fixed to the door sheet metal 7. During installation, simply place the bright strip assembly and snap-fit connector against the outside of the door sheet metal 7 and apply pressure towards the door sheet metal 7 to engage the moving end of the snap-fit connector with the mounting hole of the door sheet metal 7. During production, mounting holes need to be drilled in the door sheet metal 7 according to the location of the mounting point. To improve installation stability, a sealing horizontal section is left at the location where the hole needs to be drilled in the door sheet metal 7. The sealing horizontal section is completely parallel to the inner wall of the frame 2; the mounting hole is drilled on the sealing horizontal section to ensure the stability of the snap-fit connector engagement.
[0081] In this embodiment, a skeleton 2 is added to the inner side of the bright strip body 1 to improve the support strength of the bright strip body 1 and keep the bright strip body 1 under uniform force, thereby avoiding deformation of the bright strip body 1 due to large local force; the skeleton 2 is connected to the fixed end of the locking component as a support structure. When installing the skeleton 2 and the bright strip body 1, you only need to align the free end of the locking component on the inner side of the skeleton 2 with the mounting hole of the door sheet metal 7 and press it down, which is convenient for installation.
[0082] In some embodiments, each set of locking components provided on the frame 2 includes multiple locking members, and the multiple locking members of the same set of locking components are spaced apart along the length direction of the frame 2. For example... Figure 2 As shown, there are two locking components in the same locking assembly group, located near the two ends of the frame 2 along the length of the door. Fixing the two ends of the frame 2 ensures its installation stability. The spacing between the two locking components in the same group can be set according to actual installation requirements. For example, in... Figure 2 As can be seen, the spacing between the two locking parts in the same locking assembly is different, with the spacing between the two locking parts being smaller on the side closer to the window opening.
[0083] The locking component includes a buckle seat and a buckle body. The buckle seat is fixedly connected to the frame 2. The buckle body is connected to the buckle seat, and the free end of the buckle body has a snap-fit part that snaps into the mounting hole on the door sheet metal 7.
[0084] The buckle body includes a base 45, a main body 43, a cantilever 44, and a hook. The main body 43 is vertically connected to the base 45. One or two cantilever 44 are provided on the outer side of the main body 43. The cantilever 44 generates elastic force through bending or stretching deformation, so that the buckle can engage or disengage with the mounting hole. A hook protruding outward is provided at the end of the cantilever 44, and the hook directly engages with the mounting hole.
[0085] The buckle seat is injection molded onto the frame 2, and the base 45 of the buckle body is integrally injection molded onto the frame 2 during the manufacturing of the buckle seat. The main body 43 extends perpendicularly to the base 45 toward the side facing the door sheet metal 7. The buckle body can be a single-arm or double-arm elastic buckle.
[0086] During installation, align the buckle body with the mounting hole on the door sheet metal 7, press it into the mounting hole, so that the hook on the cantilever 44 engages with the mounting hole to complete the locking.
[0087] In this embodiment, the buckle body is connected to the frame 2 by the buckle seat, which is convenient to process and has high connection strength; and multiple locking parts are arranged at intervals along the length direction of the frame 2 to form a set of locking components, realizing multi-point installation in the length direction of the frame 2; through multi-point snap-fit, a stable connection between the frame 2 and the door sheet metal 7 is achieved.
[0088] Optionally, the clip holder can be a cylindrical structure, completely covering the base 45 of the clip body. A mating gap is formed between the end face of the clip holder and the cantilever 44. During installation, once the cantilever 44 is properly positioned with the mounting hole, the door sheet metal 7 fits against the end face of the clip holder. That is, after installation, one end of the clip holder is injection-molded onto the frame 2, and the other end abuts against the door sheet metal 7, supporting the door sheet metal 7 around the mounting hole, preventing deformation of the door sheet metal 7, and improving the stability of the snap-fit. The clip holder forms a support structure between the frame 2 and the door sheet metal 7, ensuring support strength around the mounting hole; the clip holder also seals the gap between the mounting hole and the clip body, improving the sealing effect.
[0089] like Figure 7 As shown, the above-mentioned buckle seat may include a support part 41 and a deformable part 42. The support part 41 is connected to the frame 2, and the deformable part 42 is connected to the side of the support part 41 away from the frame 2. The cross-sectional area of the deformable part 42 gradually increases in the direction away from the support part 41. The deformable part 42 is used to fit onto the door sheet metal 7. The buckle body is connected to the support part 41, and the free end of the buckle body passes through the deformable part 42 to connect to the mounting hole.
[0090] The buckle seat is divided into two parts. The support part 41, as the bottom structure, is directly connected to the frame 2. The support part 41 has an internal cavity, and the base 45 of the buckle body is fixed in the cavity. After the support part 41 is injection molded, the deformable part 42 is injection molded. The deformable part 42 can be frustoconical, and the cross-sectional area of the deformable part 42 gradually increases along the injection direction. A through hole is opened in the deformable part 42, and the inner sidewall of the through hole fits against the outer sidewall of the main body 43 of the buckle body. The aforementioned fitting gap is formed between the deformable part 42 and the cantilever 44. During installation, the door sheet metal 7 is snapped into this fitting gap.
[0091] The end face of the deformable part 42 away from the support part 41 is the support surface, and the support surface is attached to the door sheet metal 7.
[0092] The cross-sectional change of the deformable part 42 makes it easier for the deformable part 42 to undergo local deformation, which is easier to adapt to the local spacing changes between the door sheet metal 7 and the frame 2 and improves the fitting effect. In addition, since the deformable part 42 is frustoconical, its support strength gradually decreases from the middle to the outer edge, ensuring that the support force is stronger closer to the mounting hole. At the same time, the support force of the deformable part 42 gradually decreases radially along the mounting hole, so that it forms a transitional support effect around the mounting hole of the door sheet metal 7, and avoids the door sheet metal 7 from deforming due to excessive force on the mounting hole.
[0093] In some embodiments, such as Figure 5As shown, the bright strip body 1 and the frame 2 are connected by a clip 3; the clip 3 includes a connecting part 31 and a bending part 32; the connecting part 31 is connected to the inner side of the bright strip body 1; the bending part 32 is connected to the connecting part 31, and the bending part 32 passes through the positioning hole of the frame 2 and presses the frame 2 onto the inner side of the bright strip body 1.
[0094] Both the connecting part 31 and the bending part 32 are sheet-like structures. The bending part 32 has two states: an initial state and a working state. When the bending part 32 is in the initial state, the bending part 32 is perpendicular to the connecting part 31, that is, the bending part 32 is perpendicular to the frame 2. When the bending part 32 is in the working state, the part of the bending part 32 that extends out of the frame 2 is bent and attached to the inner wall of the frame 2.
[0095] First, the connecting portion 31 and the bent portion 32 need to be pre-processed. The connecting portion 31 and the bent portion 32 can be fixed by welding, or the bent portion 32 and the connecting portion 31 can be formed by bending a sheet-like structure.
[0096] When the connecting part 31 and the bending part 32 are welded, the first end of the bending part 32 abuts vertically against the end face of the connecting part 31; the bending part 32 and the connecting part 31 form a T-shaped structure or an L-shaped structure.
[0097] When the bent portion 32 and the connecting portion 31 are formed by bending the sheet-like structure, the sheet-like structure is T-shaped before bending and is bent along the extended edge at a bending angle of 90°. After bending, the body of the sheet-like structure forms the connecting portion 31, and the bent portion forms the bent portion 32. To improve connection stability, the width of the connecting portion 31 is greater than the width of the bent portion 32.
[0098] Next, the clip 3 is fixed to the bright strip body 1. The side of the connecting part 31 closest to the bright strip body 1 is rectangular, which fits against the bright strip body 1 and is glued to the inner wall of the bright strip body 1. The bent part 32 formed by bending is perpendicular to the connecting part 31 and corresponds one-to-one with the positioning holes on the frame 2.
[0099] Since the bending part 32 is a sheet-like structure, it can only be bent towards its front and rear end faces. To facilitate subsequent bending and fixing, the bending direction of the bending part 32 is consistent with the width direction of the frame 2. The positioning holes on the frame 2 are rectangular holes, with the length direction of the positioning holes consistent with the length direction of the frame 2 and the width direction of the positioning holes consistent with the width direction of the frame 2.
[0100] Finally, the clip 3 is fixed to the frame 2. When installing the bright strip body 1 and the frame 2, the free end of the bent part 32 passes through the positioning hole of the frame 2 and extends out from the other side of the frame 2. The part of the bent part 32 that extends out of the frame 2 needs to be bent twice. After the second bend, the bent part 32 fits against the surface of the frame 2 and fixes the frame 2 to the inside of the bright strip body 1.
[0101] In this embodiment, the clip 3 connects the bright strip body 1 and the skeleton 2, replacing the original adhesive connection with a snap-fit connection, thus improving the connection strength; it also increases the overall rigidity of the bright strip assembly and reduces its deformation under stress. The connecting part 31 of the clip 3 is located between the bright strip body 1 and the skeleton 2 and is connected to the bright strip body 1. Compared with the traditional method where the skeleton 2 is completely glued to the bright strip body 1, the adhesive area of the connecting part 31 of the clip 3 is smaller; the bending part 32 limits the skeleton 2 to the inside of the bright strip body 1 by penetrating the skeleton 2 and bending it again, which can improve the connection strength between the skeleton 2 and the bright strip body 1.
[0102] Multiple sets of clips 3 are provided, with adjacent sets of clips 3 spaced apart along the width direction of the bright strip body 1. Each set of clips 3 includes multiple clips, with multiple clips 3 in the same set spaced apart along the length direction of the bright strip body 1; while the clips 3 in adjacent sets are spaced apart along the width direction of the bright strip body 1. The clips 3 in adjacent sets are staggered along the length direction of the bright strip body 1. Based on the above distribution of clips 3, a uniformly distributed multi-point snap-fit fixing structure is formed between the frame 2 and the bright strip body 1, which improves the connection strength between the frame 2 and the bright strip body 1 and the uniformity of the stress on the bright strip body 1.
[0103] In addition, the fixed connection between the frame 2 and the bright strip body 1 improves the overall rigidity of the bright strip assembly. Under the rigidity of the frame 2, the bright strip body 1 fits more closely to the car door.
[0104] Optionally, the clip 3 includes an outer ring clip 3, an inner ring clip 3, and a middle clip 3 distributed sequentially along the width direction of the bright strip body 1. The inner ring clip 3 is located on the side of the bright strip body 1 closest to the window opening, the outer ring clip 3 is located on the side of the bright strip body 1 furthest from the window opening, and the middle clip 3 is located between the inner ring clip 3 and the outer ring clip 3.
[0105] The outer ring retainer 3 includes two outer end retainers 3 located at the ends of the bright strip body 1. The distance between the outer end retainers 3 and the outer corners of the bright strip body 1 must be within 35mm. Several outer inner retainers 3 are also provided between the two outer end retainers 3. These multiple outer ring retainers 3 are evenly spaced. It is worth noting that the outer corners of the bright strip body 1 refer to the two corner points on the side of the bright strip furthest from the window opening.
[0106] The inner ring retainer 3 comprises multiple retainers, all of which are equidistant from the first edge of the frame 2. Furthermore, the inner ring retainers 3 are located outside the sealing ring 8. It is noteworthy that the first edge of the frame 2 is the edge of the frame 2 closest to the window opening.
[0107] In one embodiment, such as Figure 10As shown, the bright strip assembly includes a first bright strip portion 9 located above the window and a second bright strip portion 10 located on the side of the window. The first bright strip portion 9 and the second bright strip portion 10 are connected as a whole, and the width of the second bright strip portion 10 is smaller than the width of the first bright strip portion 9.
[0108] The first bright strip 9 serves as the main structure and is fixed to the door sheet metal 7 using the locking assembly described above. The first bright strip 9 includes multiple sets of clips 3 connecting the bright strip body 1 and the frame 2. Due to width limitations, the second bright strip 10 does not require a locking assembly; the second bright strip 10 is fixed to the outside of the door sheet metal 7 by relying on the first bright strip 9.
[0109] To improve the strength of the second bright strip section 10, the bright strip body 1 and the frame 2 of the second bright strip section 10 are still fixed by clips 3. At least one set of clips 3 is arranged on the second bright strip section 10. When there is one set of clips 3, the distance between the edge of the clip 3 and the first edge of the frame 2 is the same as the distance between the inner ring clip 3 on the first bright strip section 9 and the first edge of the frame 2. When there are multiple sets of clips 3 on the second bright strip section 10, the distance between the clip 3 closest to the window opening and the first edge of the frame 2 is the same as the distance between the inner ring clip 3 on the first bright strip section 9 and the first edge of the frame 2.
[0110] In some embodiments, such as Figure 4 , Figure 5 As shown, the door window frame bright strip mounting structure also includes a door sealing strip 6, which surrounds the edge of the door sheet metal 7, and the edge of the bright strip assembly engages with the lip of the door sealing strip 6.
[0111] The door sealing strip 6 is arranged around the edge of the door. The door sealing strip 6 has a U-shaped sealing structure, with its open side facing the door sheet metal 7 and used to snap and seal the edge of the door sheet metal 7.
[0112] The door sealing strip 6 has several outwardly protruding lips on the side near the bright strip assembly. The bright strip assembly fits into the lips and is snapped and covered by the lips to prevent its edges from being exposed.
[0113] The edge of the bright strip assembly has an inward fold, which makes the outer edge of the bright strip assembly a smooth transition surface. The fold covers the inner side of the frame 2, preventing the edge of the frame 2 from being exposed and damaging the door seal 6. The lip of the door seal 6 is fitted with the transition surface of the fold, covering the edge of the fold in the cavity between two adjacent lips.
[0114] Compared to the traditional method of adhesively bonding the frame 2 to the bright strip body 1, and considering the longer cantilever of the frame 2 in the width direction, which requires a larger thickness to maintain its rigidity and reduce the surface difference between the bright strip assembly and the door, this embodiment improves the snap-fit connection strength between the frame 2 and the bright strip body 1. Furthermore, the multi-point mounting and fixing of the frame 2 to the door sheet metal 7 reduces the cantilever length and improves the installation stability of the frame 2. Therefore, the frame 2 can be relatively thinner, making its production and installation more convenient, while also reducing material costs.
[0115] Because the lip of the door seal strip 6 fits against the frame 2 at the edge of the door, it provides support to the frame 2. Conversely, the frame 2 also exerts a reverse force on the door seal strip 6, causing it to tilt inwards. When the door seal strip 6 tilts inwards, it causes interference between the door seal strip 6 and the edge of the side window. When the door is opened, the lip of the door seal strip 6 will scrape against the side window. This scraping between the lip of the door seal strip 6 and the side window leads to surface wear and deformation of the sealing lip, resulting in poor sealing, abnormal noise, reduced lifespan of the door seal strip 6, and increased maintenance costs.
[0116] With the thickness of frame 2 reduced, it will not exert much pressure on the sealing strip, allowing the sealing strip to tilt outwards compared to the traditional position. The sealing strip is closer to the outside of the vehicle, avoiding scratches with the side windows.
[0117] Optionally, the thickness of the skeleton 2 can be reduced to 2.5 mm.
[0118] Based on the same inventive concept, this application also provides a door assembly that adopts the above-mentioned door window frame bright strip mounting structure.
[0119] Compared with the prior art, the door assembly provided in this application adopts the above-mentioned door window frame bright strip mounting structure.
