Description

Technical Field

[0001] The utility model relates to the technical field of automobile assembly parts, and more specifically, to a plate - type buckle. Background Art

[0002] In the former automotive industry, basically each buckle corresponds to a fixed matching environment and usage method. Although the matching dimensions of some buckles can fluctuate within a very small range, their functions are single.

[0003] With the pursuit of lightweight in the automotive industry, many positions that traditionally used sheet metal are replaced with carbon fiber or organic resin materials. A decorative part covering such a position may need to be assembled with two or more different sheet metal parts simultaneously. For traditional buckles, one type of buckle can only be used to fasten a sheet metal part of one material. For such decorative parts, two or more types of buckles need to be assembled. In practical applications, the assembly efficiency of workers decreases, and the probability of errors increases significantly. Although some buckles can be installed on multiple sheet metal parts, their heads will protrude outside the decorative surface of the decorative part, affecting the aesthetics of the installation position and cannot be used in positions with appearance requirements. That is, the buckles in the prior art have single functions and low versatility, and cannot meet the installation requirements in specific situations. Summary of the Utility Model

Therefore, it should not be construed as a limitation to the present utility model.

[0034] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating relative importance or the number of technical features. In the description of the present utility model, the meaning of "a plurality" is two or more, unless otherwise specifically defined. The following describes the specific implementation of the present utility model in more detail with reference to specific embodiments:

[0035] As Figure 1 , Figure 2 and Figure 3 shown, wherein, Figure 2 is a cross-sectional view taken along the radial direction of the third locking leg 4, Figure 3 is a cross-sectional view taken along the length direction of the second reinforcing rib 7. An embodiment of the present utility model provides a plate-shaped buckle 100 for connecting a decorative member 10 and a sheet metal member 20, including a fixing column 1, a first locking leg 2, a second locking leg 3, and at least one third locking leg 4; the first locking leg 2 is connected to the top of the fixing column 1; the second locking leg 3 is connected to the fixing column 1, and the first locking leg 2 and the second locking leg 3 are spaced apart to form a limiting groove 5 for clamping the decorative member 10; the third locking leg 4 is used for clamping into the mounting hole 21 of the sheet metal member 20; wherein, a first reinforcing rib 6 is provided at the bottom of the second locking leg 3, a second reinforcing rib 7 is provided on the circumferential side of the fixing column 1, and the first reinforcing rib 6 is connected to the second reinforcing rib 7. The first locking leg 2 and the second locking leg 3 are spaced apart to form a limiting groove 5 for clamping the decorative member 10, the third locking leg 4 can be clamped into the mounting hole 21 of the sheet metal member 20, and the fixing column 1 connects the first locking leg 2, the second locking leg 3, and the third locking leg 4, thereby realizing the assembly connection between the decorative member 10 and the sheet metal member 20. A first reinforcing rib 6 is provided at the bottom of the second locking leg 3, a second reinforcing rib 7 is provided on the circumferential side of the fixing column 1, and the first reinforcing rib 6 is connected to the second reinforcing rib 7. By the strengthening effect of the first reinforcing rib 6 and the second reinforcing rib 7 on the structure of the plate-shaped buckle, the root of the buckle (i.e., the second locking leg 3 and the fixing column 1) can be prevented from breaking during installation.

[0036] As an alternative implementation of this embodiment, there are multiple third pins 4, and the multiple third pins 4 are arranged at intervals along the length direction of the fixing post 1. The corresponding number of third pins 4 can be selected according to the number or thickness of the sheet metal parts 20 to be installed (that is, the number of third pins 4 is not less than the number of sheet metal parts 20). Design the number according to requirements. The more the number, the greater the thickness or number of sheet metal parts 20 that can be clamped. At the same time, the fixing post 1 will be longer and the unit cost will be higher; on the contrary, the number of third pins 4 can be reduced to reduce the cost.

[0037] As an alternative implementation of this embodiment, it further includes a frustum-shaped buckle head 8. The first pin 2 is connected to one end of the fixing post 1, and the buckle head 8 is connected to the other end of the fixing post 1. The buckle head 8 can effectively solve the problem that the fixing post 1 is misaligned with the mounting hole 21 of the sheet metal part 20 during the assembly process, which affects the low assembly efficiency due to jamming; the solid structure of the buckle head 8 ensures that the buckle head collides with the edge of the sheet metal part 20 or the mounting hole 21 multiple times without damage.

[0038] As an alternative implementation of this embodiment, the top of the fixing post 1 has a hollowed-out hole 11.

[0039] As an alternative implementation of this embodiment, the second pin 3 includes a mounting plate 31 and an edge 32. The mounting plate 31 is connected to the fixing post 1, and the edge 32 is connected to the periphery of the mounting plate 31. The edge 32 is inclined downward.

[0040] As an alternative implementation of this embodiment, the thickness of the edge 32 is less than the thickness of the mounting plate 31. That is, the second pin 3 is thinned, so as to reduce the use of materials while ensuring the strength, thereby reducing the manufacturing cost.

[0041] As an alternative implementation of this embodiment, a round chamfer 321 is provided at one end of the edge 32 away from the mounting plate 31. To prevent sharp edges from hurting the assembly personnel.

[0042] As an alternative implementation of this embodiment, a protrusion 33 is provided at the connection between the mounting plate 31 and the edge 32. The distance between the protrusion 33 and the first clamping foot 2 is less than the distance between the mounting plate 31 and the first clamping foot 2. This ensures that the mounting plate 31 and the first clamping foot 2 can form a certain clamping force on the decorative part 10 without increasing the assembly force. The protrusion 33 forms a certain angle with the surface of the sheet metal part 20, and the protrusion 33 bends towards the sheet metal part 20. When the sheet metal part 20 is assembled to the third clamping foot 4, the end of the edge 32 abuts against the sheet metal part 20 at this time, the top of the protrusion 33 abuts against the decorative part 10, and the second clamping foot 3 is squeezed by the sheet metal part 20, which will provide a greater clamping force to the decorative part 10, thereby making the dimensional position of the decorative part 10 more stable. In addition, the edge 32 and the sheet metal part 20 will form a sealing surface, thereby achieving a certain waterproof and dustproof effect. When necessary, a sealing member 9 (for example, a circular foam or a secondary injection molded soft rubber) is added between the edge 32 and the sheet metal part 20 to achieve a higher waterproof and dustproof effect.

[0043] As an alternative implementation of this embodiment, the third clamping foot 4 is provided with a mounting groove 41 along the radial direction of the fixing post 1, and the second reinforcing rib 7 is arranged in the mounting groove 41. By providing the mounting groove 41 on the third clamping foot 4, the use of materials can be reduced while ensuring the strength, thereby reducing the manufacturing cost.

[0044] As an alternative implementation of this embodiment, the material of the plate-like buckle 100 is polyoxymethylene or polyamide resin. The above materials all have a certain material strength, which can ensure that the strength of the overall structure meets the use requirements.

[0045] As Figure 4 shown in the figure, in this embodiment, the buckle seat 102 of the decorative part 10 is clamped between the first clamping foot 2 and the second clamping foot 3, the decorative surface 101 of the decorative part 10 faces outwards, and the third clamping foot 4 is clamped on the mounting hole 21 of the sheet metal part 20 to realize the function of fixing the decorative part 10. This installation method allows the minimum thickness and the maximum thickness of the sheet metal part 20 to differ by several times or even more than a dozen times, and also allows the sheet metal part 20 to be one layer or multiple layers, as long as the maximum thickness that the buckle can be clamped is not exceeded. The maximum thickness of the buckle is related to the number of the third clamping feet 4.

[0046] As Figure 5 shown in the figure, in this embodiment, the buckle seat 102 of the decorative part 10 is clamped between the first clamping foot 2 and the second clamping foot 3, the decorative surface 101 of the decorative part 10 faces outwards, the third clamping foot 4 is clamped on the waterproof buckle seat 30, and the waterproof buckle seat 30 is installed in the mounting hole 21 of the sheet metal part 20 to be used for positioning the decorative plate 10, fixing the decorative plate 10, separating and sealing both sides of the sheet metal part 20 and other functions.

[0047] As Figure 6 and Figure 7As shown in the figure, in this embodiment, the buckle seat 102 of the decorative part 10 is clamped between the first clamping leg 2 and the second clamping leg 3, and multiple third clamping legs 4 are respectively clamped on the mounting holes 21 of multiple sheet metal parts 20. This embodiment has a large tolerance. Even if the decorative part 10 or the sheet metal part 20 is finely adjusted, the buckle can still meet the requirements. It can clamp multiple layers of sheet metal parts 20 at the same time and can achieve the functions of waterproofing and dustproofing.

[0048] The utility model not only takes into account the appearance of the decorative part 10, but also solves the cost problem caused by the small matching size adaptation range (the need to increase the types of buckles), and also reduces the risk of errors caused by using multiple types of buckles in the production process. At the same time, the invention structurally ensures high strength and minimizes the molding material of the buckle.

[0049] In multiple positions of the vehicle, including but not limited to the upper decorative part in the front compartment, the water trough decorative plates on both sides of the rear door, etc., the plate-type buckle of the utility model is used to solve the problem that the appearance, waterproof stability, and assembly efficiency of the decorative part cannot be compatible at the same time; the utility model can also fix multiple products at the same time.

[0050] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
