Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle sunroof components, and more particularly to a fixing clip for a vehicle sunroof return pipe and a vehicle sunroof. Background Technology
[0002] Car sunroofs use a motor-driven flexible shaft to open and close the sunroof glass and sunshade. The protective sleeve (i.e., return tube) of the flexible shaft needs to be fixed to the sunroof guide rail using clips, cable ties, or other structures. With the development of automotive intelligence, the number of devices integrated into the roof (such as LiDAR and displays) is increasing, resulting in a significant reduction in the space available for sunroof systems.
[0003] Existing flexible shaft return tube clips mostly employ claw, plug-in, or adhesive methods, and are typically arranged with a single point on one side or a double point on one side. When the flexible shaft return tube needs to be arranged in two layers, if the two layers of return tube are fixed by clips on one side, it will inevitably occupy too much of the arrangement space on that side, which may not only cause interference between the return tubes themselves, but also interference with other components. If the two layers of return tube are fixed with a single point on one side, two independent clips are usually required, resulting in a significant increase in the number of parts and cumbersome assembly. Utility Model Content
[0004] One object of this application is to provide a fixing clip for a vehicle sunroof return pipe and a vehicle sunroof, at least to solve the above-mentioned problems.
[0005] To achieve the above objectives, some embodiments of this application provide a fixing clip for a vehicle sunroof return pipe and a vehicle sunroof, including:
[0006] The base has a first and a second assembly slot arranged at intervals with their openings facing away from each other. Both the first and second assembly slots are configured to be able to be inserted into the mounting slots on the sunroof guide rail or the sunroof frame.
[0007] In this configuration, on the two symmetrical sidewalls of the first assembly slot, the ends away from the opening of the second assembly slot are bent and extended in a direction away from the opening of the first assembly slot, forming a first snap-fit part and a second snap-fit part.
[0008] A first snap-fit groove is formed between the first snap-fit part and the base, and a second snap-fit groove is formed between the second snap-fit part and the base; both the first snap-fit groove and the second snap-fit groove are configured to snap-fit and fix the return pipe of the vehicle sunroof.
[0009] Some embodiments of this application also provide a vehicle sunroof, including a sunroof frame, a guide rail, and the aforementioned fixing buckle for the vehicle sunroof return pipe; when the fixing buckle is assembled with the sunroof guide rail or the sunroof frame, the first locking part and the second locking part are respectively located on both sides of the sunroof guide rail or the sunroof frame.
[0010] The sunroof frame and / or guide rail are equipped with a return pipe, which can be selectively snapped into the first and / or second snap-fit grooves of the fixing buckle.
[0011] Compared with related technologies, the solution provided in this application embodiment uses a double assembly slot with spaced intervals and opposite openings integrated into the substrate, which can be stably inserted into the sunroof guide rail or frame. The symmetrical snap-fit portion extending from the side wall of the first assembly slot forms a double snap-fit slot, which not only achieves bidirectional fixing of the return pipe but also ensures that the double snap-fit slots are located on both sides of the sunroof guide rail or frame, improving the space utilization on both sides of the guide rail or frame. The overall structure integrates assembly and fixing functions, reducing parts and assembly processes, saving space and avoiding interference. The symmetrical snap-fit enhances the return pipe's resistance to bumps and prevents abnormal noises. The double assembly slot and double snap-fit slot design adapts to different specifications of components, improving versatility, while the integrated structure reduces stress concentration and extends service life.

[0028] Combination Figures 1 to 5 As shown in the embodiment of this disclosure, the fixing buckle for the sunroof return pipe of a vehicle includes: a base 101, with a first mounting groove 1011 and a second mounting groove 1012 arranged at intervals and with their openings facing away from each other. Both the first mounting groove 1011 and the second mounting groove 1012 are configured to be inserted into the sunroof guide rail 20 or the mounting groove 201 on the sunroof frame. On the two symmetrical sidewalls of the first mounting groove 1011, the ends away from the opening of the second mounting groove 1012 are bent and extended in a direction away from the opening of the first mounting groove 1011, forming a first snap-fit portion 102 and a second snap-fit portion 103. A first snap-fit groove 1021 is defined between the first snap-fit portion 102 and the base 101, and a second snap-fit groove 1031 is defined between the second snap-fit portion 103 and the base 101. Both the first snap-fit groove 1021 and the second snap-fit groove 1031 are configured to snap-fit and fix the return pipe 30 of the vehicle sunroof.
[0029] The fixing buckle 10 provided in this embodiment integrates two spaced and oppositely spaced assembly slots on the base 101, which can be stably inserted into the sunroof guide rail 20 or frame. Combined with the symmetrical snap-fit portion extending from the side wall of the first assembly slot 1011, a double snap-fit slot is formed, which not only achieves bidirectional fixing of the return pipe 30, but also ensures that the double snap-fit slots are located on both sides of the sunroof guide rail 20 or frame, improving the space utilization on both sides of the guide rail 20 or frame. The overall structure integrates assembly and fixing functions, reducing parts and assembly processes, saving space and avoiding interference. The symmetrical snap-fit enhances the anti-bump stability of the return pipe 30 and prevents abnormal noise. The design of the double assembly slot and double snap-fit slot is adaptable to different specifications of components, improving versatility. At the same time, the integrated structure reduces stress concentration and extends service life.
[0030] The central region of the base 101 is machined at intervals along its length to form a first assembly groove 1011 and a second assembly groove 1012. The groove openings of the first assembly groove 1011 and the second assembly groove 1012 are arranged in opposite directions, and the groove structure of both is adapted to the contour of the pre-set mounting groove 201 on the sunroof guide rail 20 or the sunroof frame (the groove width and groove depth of both can be adaptively adjusted according to the thickness of the sunroof guide rail 20 or the sunroof frame), so that the inner sidewalls of the first assembly groove 1011 and the second assembly groove 1012 form an interlocking fit with the mounting groove 201 on the sunroof guide rail 20 or the sunroof frame of different thicknesses.
[0031] The first assembly groove 1011 has two opposing and parallel symmetrical sidewalls. The ends of the two symmetrical sidewalls that are away from the opening of the second assembly groove 1012 are bent and extended in a direction away from the opening of the first assembly groove 1011 to form a first snap-fit part 102 and a second snap-fit part 103 integrally connected to the ends of the sidewalls. The bending angles of the first snap-fit part 102 and the second snap-fit part 103 are the same, and the two are symmetrically distributed about the central axis of the first assembly groove 1011.
[0032] The free end of the first snap-fit part 102 forms a first snap-fit groove 1021 with an opening facing the second assembly groove 1012 between itself and the outer wall of the base 101. The free end of the second snap-fit part 103 forms a second snap-fit groove 1031 with an opening facing the second assembly groove 1012 between itself and the outer wall of the base 101. The inner walls of the first snap-fit groove 1021 and the second snap-fit groove 1031 are completely fitted to the outer wall contour of the vehicle sunroof return pipe 30, so that the return pipe 30 is snapped and fixed by the clamping action of the first snap-fit part 102 and the second snap-fit part 103 with the base 101. The groove width, groove depth and inner wall curvature radius of the first snap-fit groove 1021 and the second snap-fit groove 1031 can be adaptively adjusted according to the outer diameter of the return pipe 30, so that the inner wall of the snap-fit groove fits the outer wall of the return pipe 30 with different outer diameters, so as to achieve snap-fit fixing of return pipes 30 of different specifications.
[0033] The base 101 forms a stable connection with the mounting slot 201 of the sunroof guide rail 20 / frame through the spaced first mounting slot 1011 and second mounting slot 1012. Simultaneously, the first snap-fit part 102, the second snap-fit part 103, and the snap-fit slot defined by the base 101 integrate the fixing function of the return pipe 30 with the snap-fit assembly function. This eliminates the need for multiple separate components to connect the snap-fit to the guide rail 20 and fix the return pipe 30, reducing the number of parts and assembly steps, and lowering assembly costs. Furthermore, the symmetrically distributed snap-fit parts and mounting slots have a compact layout, significantly reducing the space occupied by the snap-fit inside the sunroof and avoiding interference with other sunroof components (such as the drive mechanism and seals), thus adapting to the limited space requirements inside the vehicle sunroof.
[0034] The first snap-fit groove 1021 and the second snap-fit groove 1031 form a bidirectional clamping structure through the cooperation of the symmetrical snap-fit parts with the base 101. The structural design of the snap-fit parts bending in the direction away from the opening of the first assembly groove 1011 makes the opening direction of the snap-fit groove and the insertion direction of the assembly groove mechanically complementary, ensuring that the fixing force of the return pipe 30 and the snap-fit assembly force do not interfere with each other, and further improving the stability of the overall structure.
[0035] The base 101, the first snap-fit part 102, and the second snap-fit part 103 are integrally formed, avoiding the weak connection points of the split structure. The mechanical structure formed by the first snap-fit part 102 and the second snap-fit part 103 extending from the side wall of the first assembly groove 1011 allows the force during snap-fit to be dispersed through the base 101 to the contact area between the assembly groove and the guide rail 20, reducing local stress concentration and reducing the risk of deformation or breakage of the buckle due to long-term stress.
[0036] In this embodiment, the fixing buckle 10 makes full use of the vehicle's Z-axis space to achieve a compact arrangement of the upper and lower return pipes 30, greatly reducing the lateral space occupied by the buckle in the X / Y direction, effectively avoiding gap interference with components such as the roof reinforcing ring, roof, and lidar, solving the problem of insufficient arrangement space in the prior art, and adapting to the arrangement needs of the increasing roof equipment under the development of automotive intelligence.
[0037] Optionally, when the base 101 is assembled with the sunroof guide rail 20 or the sunroof frame, the first snap-fit part 102 and the second snap-fit part 103 are located on both sides of the sunroof guide rail 20 or the sunroof frame, respectively. This allows the double snap-fit grooves to be symmetrically distributed on both sides of the guide rail 20 / frame, enabling independent fixing and layered arrangement of the return pipes 30 on both sides, significantly improving space utilization and avoiding mutual interference between the return pipes 30. At the same time, the snap-fit parts on both sides form a symmetrical force-bearing structure, ensuring balanced force after snap-fit assembly and reducing local stress concentration.
[0038] When the base 101 is assembled with the sunroof guide rail 20 or the sunroof frame mounting groove 201 through the first mounting groove 1011 and the second mounting groove 1012, the first snap-fit part 102 and the second snap-fit part 103 are respectively located on both sides of the sunroof guide rail 20 or the sunroof frame, and the inner sidewalls of the first snap-fit part 102 and the second snap-fit part 103 maintain a preset gap with the outer sidewalls of the sunroof guide rail 20 or the sunroof frame, so as to avoid interference between the first snap-fit part 102 and the second snap-fit part 103 and the guide rail 20 / frame after assembly.
[0039] Optionally, the opening directions of the first snap-fit groove 1021 and the second snap-fit groove 1031 are both oriented toward the second assembly groove 1012, and the inner sidewalls of the first snap-fit groove 1021 and the second snap-fit groove 1031 are both adapted to the outer sidewall of the return pipe 30.
[0040] The groove depth of the first locking groove 1021 is the same as that of the second locking groove 1031, and the groove width of both is slightly smaller than the outer diameter of the return pipe 30. The inner sidewalls of the first locking groove 1021 and the second locking groove 1031 are provided with arc-shaped transition surfaces. The radius of curvature of the arc-shaped transition surfaces is equal to or close to the outer radius of the return pipe 30, so as to achieve surface contact between the locking groove and the return pipe 30.
[0041] Optionally, the first assembly groove 1011 penetrates the base 101 along a direction perpendicular to the plane where the opening of the first assembly groove 1011 is located, and the opening of the first assembly groove 1011 is its opening along the depth direction; the second assembly groove 1012 penetrates the base 101 along a direction perpendicular to the plane where the opening of the second assembly groove 1012 is located, and the opening of the second assembly groove 1012 is its opening along the depth direction. The through-type structure facilitates positioning and alignment during assembly, reducing installation difficulty; the design of the groove opening along the depth direction allows the insertion force to be evenly transmitted along the depth direction, reducing the risk of deformation of the base 101.
[0042] Along the direction perpendicular to the plane where the opening of the first assembly groove 1011 is located, the first assembly groove 1011 completely penetrates the front and rear end faces of the base 101, and the opening of the first assembly groove 1011 is its only opening along the depth direction; the penetration direction of the second assembly groove 1012 is consistent with that of the first assembly groove 1011, and the groove depth of the second assembly groove 1012 is the same as that of the first assembly groove 1011, so as to ensure that the base 101 is subjected to balanced force when it is inserted into the mounting groove 201.
[0043] Optionally, the base 101 is provided with a deformation groove 1013 between the first assembly groove 1011 and the second assembly groove 1012. The deformation groove 1013 is used to provide deformation space when the first assembly groove 1011 and the second assembly groove 1012 are inserted and assembled. The plane where the opening of the deformation groove 1013 is located along the depth direction is perpendicular to the plane where the groove opening of the first assembly groove 1011 is located.
[0044] A deformation groove 1013 is formed in the area between the first assembly groove 1011 and the second assembly groove 1012 in the base body 101. The groove body of the deformation groove 1013 extends in a direction parallel to the plane where the groove opening of the first assembly groove 1011 is located, and the groove opening is perpendicular to the groove opening of the first assembly groove 1011. The two side walls of the deformation groove 1013 are the bottom walls of the first assembly groove 1011 and the second assembly groove 1012, respectively, so as to provide space for the elastic deformation of the base body 101 when the first assembly groove 1011 and the second assembly groove 1012 are inserted into the mounting groove 201, thereby preventing the base body 101 from breaking during the assembly process.
[0045] Optionally, the first snap-fit portion 102 forms a first snap-fit claw 1022 at its end facing the first snap-fit groove 1021, and the first snap-fit claw 1022 is used to snap-fit with the return pipe 30 to fix the return pipe 30; the second snap-fit portion 103 forms a second snap-fit claw 1032 at its end facing the second snap-fit groove 1031, and the second snap-fit claw 1032 is used to snap-fit with the return pipe 30 to fix the return pipe 30.
[0046] The free end of the first latching portion 102 is bent toward the inside of the groove of the first latching groove 1021 to form a first latch 1022 integrally connected to the first latching portion 102; the bending direction of the first latch 1022 is opposite to the bending direction of the first latching portion 102, and the end of the first latch 1022 abuts against the outer wall of the return pipe 30; the free end of the second latching portion 103 forms a second latch 1032 in the same manner, and the second latch 1032 and the first latch 1022 are symmetrically distributed to enhance the fixing stability of the return pipe 30 through the abutment action between the latch and the return pipe 30.
[0047] Optionally, a first mating claw 1014 is formed on the outer wall of the base 101 facing the first snap-fit groove 1021, and the first mating claw 1014 and the first claw 1022 are correspondingly mated to further fix the return pipe 30; a second mating claw 1015 is formed on the outer wall of the base 101 facing the second snap-fit groove 1031, and the second mating claw 1015 and the second claw 1032 are correspondingly mated to further fix the return pipe 30.
[0048] On the outer wall of the base 101 facing the first snap-fit groove 1021, a first mating claw 1014 is integrally formed facing the cavity of the first snap-fit groove 1021. The first mating claw 1014 is located below the opening of the first snap-fit groove 1021, and its position corresponds vertically to the position of the first claw 1022. The distance between the two is equal to or close to the outer diameter of the return pipe 30, so that the return pipe 30 is limited in the vertical direction by the clamping engagement of the first mating claw 1014 and the first claw 1022. Similarly, a second mating claw 1015 is formed on the outer wall of the base 101 facing the second snap-fit groove 1031 in the same manner. The second mating claw 1015 and the second claw 1032 are correspondingly engaged to realize the vertical limitation of the other return pipe 30.
[0049] Optionally, the inner wall of the mounting groove 201 on the sunroof guide rail 20 or sunroof frame is formed with at least one locking structure 202, which is used to form a locking engagement with the first mounting groove 1011 and the second mounting groove 1012 to restrict the movement of the base 101 relative to the mounting groove 201.
[0050] At least one locking structure 202 is integrally formed on the inner wall of the mounting groove 201 on the sunroof guide rail 20 or the sunroof frame; the locking structure 202 is in direct contact with the inner wall of the first mounting groove 1011 and the second mounting groove 1012, so as to restrict the movement of the base 101 relative to the mounting groove 201 through the snap-fit action of the locking structure 202 and the mounting groove.
[0051] Optionally, the locking structure 202 can be any one or more combinations of serrations, protrusions, recesses, barbs, and notches.
[0052] The locking structure 202 is any one or more combinations of serrations, annular protrusions, arc-shaped recesses, barbs or rectangular notches that are spaced apart along the length of the mounting groove 201; when the locking structure 202 is serrations, the inclination direction of the serrations is opposite to the insertion direction of the base 101, so as to prevent the base 101 from coming out in the opposite direction after insertion.
[0053] Optionally, the inner sidewalls of the first assembly groove 1011 and the second assembly groove 1012 are provided with at least one protruding, raised, or recessed locking fit structure 1016 to form an interference fit with the locking structure 202 on the inner wall of the mounting groove 201.
[0054] At least one locking structure 1016, consisting of a protrusion, ridge, or recess, is integrally formed on the inner wall of the first assembly groove 1011. The inner wall of the second assembly groove 1012 forms a corresponding structure in the same manner (i.e., the second assembly groove 1012 also forms a locking structure 1016). The protrusions / ridges / recesses on the inner walls of the first assembly groove 1011 and the second assembly groove 1012 correspond in position to the locking structure 202 on the inner wall of the mounting groove 201, and the contact area between the two forms an interference fit with an interference amount of 0.1-0.3 mm to ensure the tight connection between the base 101 and the mounting groove 201 after assembly.

[0056] The fixing buckle 10 is an integral structure made of elastic material by injection molding; the base 101, the first assembly groove 1011, the second assembly groove 1012, the first snap-fit part 102, the second snap-fit part 103, the first snap-fit groove 1021, and the second snap-fit groove 1031 are integral structures formed in one piece, without splicing or assembly marks, so as to improve the structural strength and service life of the buckle.
[0057] This disclosure also provides a vehicle sunroof, including a sunroof frame, a guide rail 20, and a fixing buckle 10 for the vehicle sunroof return pipe 30 provided in the above embodiments; when the fixing buckle is assembled with the sunroof guide rail or sunroof frame, the first locking part and the second locking part are respectively located on both sides of the sunroof guide rail or sunroof frame; wherein, a chain-type return pipe 30 is installed on the sunroof frame and / or guide rail 20, and the return pipe 30 can be selectively locked into the first locking groove 1021 and / or the second locking groove 1031 of the fixing buckle 10.
[0058] A chain-type return pipe 30 is fixed to the inner wall of the sunroof frame and / or the outer wall of the guide rail 20 by bolts or welding. The extension direction of the return pipe 30 is consistent with the extension direction of the sunroof frame / guide rail 20. The fixing buckle 10 is inserted and fixed to the mounting groove 201 on the sunroof frame or guide rail 20 through the first mounting groove 1011 and the second mounting groove 1012. The return pipe 30 is correspondingly snapped into the first snap-fit groove 1021 and / or the second snap-fit groove 1031 of the fixing buckle 10.
