Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a quick-assembly automotive interior panel clip assembly. Background Technology

[0002] In automobile manufacturing and assembly, interior panels typically need to be securely and smoothly mounted on the vehicle body sheet metal. Traditional fixing methods often employ self-tapping screws, snap rings, plastic rivets, or adhesives. However, screw connections require tools, resulting in low assembly efficiency and potential damage to interior materials; while adhesive methods offer a neat appearance, they are not removable, hindering after-sales repair or recycling; and existing snap-fit ​​structures often only provide unidirectional locking, leading to insufficient locking force, easy loosening, high requirements for hole precision, and an inability to simultaneously secure both the sheet metal and the interior panel.

[0003] However, existing automotive interior panel clips are mostly single male-female mating structures, lacking a coordinated clamping mechanism between the sheet metal holes and the interior panel. This makes it difficult to simultaneously achieve both the pressing of the interior panel and the anti-detachment fixation of the clip body within the sheet metal holes without additional fasteners. While some clips have elastic locking functions, they are difficult to disassemble or prone to fatigue failure under vibration conditions; other solutions rely on complex multi-part assembly, resulting in high costs and low reliability. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a quick-assembly automotive interior panel clip assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-assembly automotive interior panel snap-fit ​​assembly, comprising sheet metal; a snap-fit ​​assembly disposed on the sheet metal, comprising a female snap fastener disposed on the top of the sheet metal; and a locking assembly disposed inside the snap-fit ​​assembly, comprising a guide positioning cone surface disposed inside the top of the female snap fastener.

[0006] As a further description of the above technical solution:

[0007] The buckle assembly includes: a guide cone disposed at the bottom of the female buckle and located inside the sheet metal; a male buckle disposed at the top of the female buckle; and a clamping plate disposed on the male buckle.

[0008] As a further description of the above technical solution:

[0009] The locking assembly includes: a guide ramp, located at the bottom of the male buckle; guide blind holes, formed on the guide cone, with multiple sets formed around the guide cone; a positioning post, located at the bottom of the guide ramp; two sets of flexible blocks, located on both sides of the guide cone; two sets of elastic buckles, located at the bottom of the positioning posts, with one side contacting and pushing one side of the flexible block; and a locking groove, formed on both sides of the bottom of the guide cone, with one end of the elastic buckle extending into the locking groove.

[0010] As a further description of the above technical solution:

[0011] A circular hole is opened in the middle of the sheet metal, and a guide cone passes through the hole.

[0012] As a further description of the above technical solution:

[0013] The bottom of the clamping plate presses down on the interior trim panel.

[0014] As a further description of the above technical solution:

[0015] The two sets of flexible blocks deform and extend on both sides of the guide cone.

[0016] As a further description of the above technical solution:

[0017] The flexible block with elastic buckle has a beveled end.

[0018] This utility model has the following beneficial effects:

[0019] 1. By using the quick-connect fitting of male and female clips, combined with the automatic locking structure of elastic buckles and locking grooves, tool-free, single-step rapid assembly between interior panels and sheet metal is achieved, improving production efficiency and reducing labor costs.

[0020] 2. The interior panel is clamped by the pressure plate and the top of the female buckle. The flexible claws expand and limit the bottom of the sheet metal hole, forming a double anti-loosening fixation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Example 1:

[0032] like Figures 1 to 5 As shown, this embodiment provides a quick-assembly automotive interior panel clip assembly, including: a sheet metal 1; a clip assembly 2, disposed on the sheet metal 1, including a female clip 21 disposed on the top of the sheet metal 1; and a locking assembly 3, disposed inside the clip assembly 2, including a guide positioning cone surface 31, which is formed inside the top of the female clip 21.

[0033] In this embodiment, the snap-fit ​​assembly 2 and the locking assembly 3 constitute a quick-assembly automotive interior panel snap-fit ​​assembly according to this application.

[0034] It should also be noted that the automotive interior trim panels in this application can be door trim panels, dashboard side panels, headliner side trim panels, etc. Figure 1 In this embodiment, the dashboard side panel is used as an example for description. Of course, other types of automotive interior panels can also adopt a similar structure, which will not be described in detail below.

[0035] Understandable Figure 1 The images shown are merely schematic representations of some components included in automotive interior trim panels; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 The limitations mean that automotive interior panels can also include, compared to Figure 1 More or fewer parts.

[0036] Furthermore, in this embodiment, sheet metal 1 is a cold-rolled steel sheet specifically for automobiles, with circular holes inside and rounded edges; the snap-fit ​​assembly 2 is compatible with automotive interior panels of different thicknesses, shortening the single-piece splicing time; the double-locking structure of the locking assembly 3 is adapted to the bumpy environment of the car, ensuring that the interior panels do not loosen. Using the automotive body sheet metal 1 as the installation base, the female snap 21 of the snap-fit ​​assembly 2 is fixed to the sheet metal hole via the guide cone 22, and the male snap 23 precisely aligns with the female snap 21; the guide positioning cone surface 31 and the guide slope surface 32 of the locking assembly 3 guide the male snap to quickly insert, the elastic snap 36 cooperates with the snap groove 37 to achieve the first layer of locking, and the flexible block 35 is deformed by compression and stuck at the bottom of the sheet metal to achieve the second layer of locking. The single-piece splicing time is improved compared to the efficiency of traditional screw fixing; it is compatible with various thicknesses of interior panels, making it highly versatile; the rounded sheet metal holes prevent scratching the snap-fit ​​assembly during installation, extending its service life.

[0037] Example 2:

[0038] Based on Embodiment 1, in order to provide a snap-fit ​​function, a snap-fit ​​assembly 2 is provided on the sheet metal 1.

[0039] Specifically, the buckle assembly 2 includes: a guide cone 22, which is disposed at the bottom of the female buckle 21 and located inside the sheet metal 1; a male buckle 23, which is disposed at the top of the female buckle 21; and a pressing plate 24, which is disposed on the male buckle 23.

[0040] In this embodiment, the female buckle 21 is made of nylon; the guide cone 22 is integrally injection molded from the same material; the male buckle 23 is made of PA66; and the clamping plate 24 is a nylon structure wrapped in TPR soft rubber. When installing the female buckle 21, align the guide cone 22 with the circular hole in the sheet metal 1, and quickly insert it using the guiding effect of the cone structure. The flexible block 35 is deformed by the hole and then resets and is stuck at the bottom of the sheet metal. When installing the male buckle 23, align the bottom of the male buckle with the guide positioning cone surface 31 of the female buckle 21, and quickly insert it under the guidance of the cone surface. The clamping plate 24 cooperates with the female buckle to clamp the interior panel, completing the initial splicing. The nylon female buckle has temperature resistance and is suitable for the extreme environment of automobiles; the tapered design improves the alignment accuracy of the female buckle installation; the TPR soft rubber clamping plate increases the friction with the interior panel while avoiding damage to the surface of the interior panel.

[0041] Example 3:

[0042] Based on embodiment 2, in order to provide a snap-lock function, a locking component 3 is provided inside the snap-lock component 2.

[0043] Specifically, the locking component 3 includes: a guide ramp 32, disposed at the bottom of the male buckle 23; a guide blind hole 33, formed on the guide cone 22, and multiple sets formed around the guide cone 22; a positioning post 34, disposed at the bottom of the guide ramp 32; two sets of flexible blocks 35, located on both sides of the guide cone 22; two sets of elastic buckles 36, located at the bottom of the positioning post 34, with one side contacting and pushing one side of the flexible block 35; and a locking groove 37, formed on both sides of the bottom of the guide cone 22, with one end of the elastic buckle 36 extending into the locking groove 37.

[0044] In a preferred embodiment, the guide positioning cone surface 31 has a conical opening; the guide slope 32 has a conical head; the guide blind hole 33 is a vertical hole, evenly distributed in a ring; the positioning post 34 is made of nylon and is integrally injection molded with the male buckle; the flexible block 35 is made of TPU elastic material. When the male buckle 23 is inserted into the female buckle 21, the guide positioning cone surface 31 fits against the guide slope 32, guiding the positioning post 34 to accurately enter the interior of the guide cone 22; the slope of the elastic buckle 36 contacts the flexible block 35, and as the male buckle is pressed down, it pushes the flexible block to deform to both sides, extending out of the guide cone and locking at the bottom of the hole in the sheet metal 1; the pressure continues until the elastic buckle 36 engages with the locking groove 37, achieving the first layer of mechanical locking, and the double locking ensures a stable splicing. The cone-shaped guide positioning cone reduces the insertion force of the male thread, making it easy for a single person to operate; the fit between the guide slope and the cone reduces the insertion deviation of the positioning post; the deformation of the TPU flexible block adapts to the errors of sheet metal of different thicknesses; the double locking increases the pull-out force of the buckle, preventing it from coming loose when the car is bumpy.

[0045] In actual use, the user first presses the end of the female buckle 21 with the guide cone 22 into the circular hole of the sheet metal 1. The bottom of the guide cone 22 enters the circular hole first, and then the top of the hole contacts the outer corner of the flexible block 35. The flexible block 35 is squeezed and deformed to both sides. Continue to press it in and pass through the hole. Then the top of the guide cone 22 contacts the hole and is squeezed and deformed into the guide blind hole 33 until the guide cone 22 passes through the hole and the female buckle 21 covers the top of the hole. Next, the user inserts the male buckle 23 through the hole in the interior panel, presses the clamping plate 24 on the top of the hole in the interior panel, and then inserts the male buckle 23 with one end of the elastic buckle 36 aligned with the top guide positioning cone surface 31 of the female buckle 21 until the two sides of the elastic buckle 36 contact one side of the flexible block 35. The positioning post 34 slides into the interior of the guide cone 22, and the guide inclined surface 32 slides inside the female buckle 21. The bottom of the clamping plate 24 and the top of the female buckle 21 clamp the interior panel. The elastic buckle 36 continues to press down and locks itself inside the locking groove 37. At the same time, it pushes the flexible block 35 to deform outward and lock it at the bottom of the circular hole in the sheet metal 1.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
