Description

Technical Field

[0001] The utility model relates to an interior trim installation structure, belonging to the technical field of vehicle fixing elements. Background Art

[0002] In the automotive interior structure, a single-sided clamp is often used to connect and fix two structural components to achieve the matching and clamping of parts with surrounding parts. As Figure 1 shown, the current single-sided clamp directly extends a deformable buckle 1 from the part body. The head of the buckle 1 is clamped with a bayonet 2 on the part to be matched and connected. Since the buckle 1 can generate displacement as a whole during the connection process, it is limited to single-sided clamping and lacks a positioning function.

[0003] In the prior art, in order to solve the problem that the single-sided clamp lacks a positioning function, a gantry clamp is designed. As Figure 2 shown, it extends an undeformable gantry insertion plate 3 from the part body, and a deformable buckle head 4 is connected to the gantry insertion plate 3. In this way, the undeformable gantry insertion plate 3 can be used to position with the bayonet on the part to be matched and connected. However, in order to meet the need for the deformability of the buckle head and at the same time not affect the positioning of the gantry insertion plate 3, the height of the gantry insertion plate 3 after passing through the bayonet will increase compared with the traditional single-sided clamp. The typical height of the gantry clamp is 15 mm while that of the traditional single-sided clamp is 7 mm. Obviously, the gantry clamp occupies more space height and affects its applicable position on the part. Summary of the Utility Model

[0004] Aiming at the above-mentioned defects of the prior art, the task of the utility model is to provide a single-sided clamp with positioning, aiming to solve the problem of lacking a positioning function while not significantly increasing the height of the single-sided clamp.

[0005] The technical solution of the utility model is as follows: A single-sided clamp with positioning includes a base, a buckle and a positioning post. The positioning post and the buckle are respectively extended from the base in the first direction. The head end of the buckle is separated from the head end of the positioning post. The positioning post is located on both sides of the buckle. At least one side wall of the positioning post is provided with a positioning surface for cooperating with the hole wall of the clamping hole for positioning.

[0006] Further, the positioning surface includes an intersecting first surface and second surface.

[0007] Further, a support boss is provided at the lower part of the positioning post, and the top surface of the support boss and the hook surface of the buckle respectively abut against the front and back sides of the component where the clamping hole is located.

[0008] Further, in order to improve the stiffness of the positioning post, the positioning post includes a plate body, and a plurality of first reinforcing ribs are provided on the side surface of the plate body.

[0009] Furthermore, the buckle includes an elastic piece and a buckle head. The buckle head is located at the head end of the elastic piece, and a plurality of second reinforcing ribs are provided on the elastic piece.

[0010] Furthermore, the buckle head is located on the front surface of the elastic piece, and the second reinforcing ribs are located on the back surface of the elastic piece.

[0011] Furthermore, the buckle head is wedge-shaped.

[0012] The advantages of the present utility model compared with the prior art are as follows:

[0013] By directly providing positioning posts for positioning on the base, and the positioning posts are separated from the buckle, it is not necessary for the parts of the single-sided card passing through the clamping holes to be connected to each other and to provide deformation support for the buckle. The single-sided card can achieve the positioning function and the height of the part passing through the clamping hole does not increase, avoiding the additional occupation of space height and expanding the applicable range of the clamping part.

[0022] The present utility model will be further described below in conjunction with embodiments, but it is not intended to limit the present utility model.

[0023] Example 1. Please refer to Figures 3 to 6 As shown in Figures 3 to 6 , a unilateral card with positioning involved in this embodiment includes a base 100, a buckle 101, and a positioning post 102. The base 100 is a plate-like structure, and both the buckle 101 and the positioning post 102 extend upward from the base 100. There are two positioning posts 102, which are located on the left and right sides of the buckle 101 and have a gap between them and the buckle 101, so that the head ends of the buckle 101 and the positioning posts 102 are separated from each other. Generally, the buckle 101, the positioning posts 102, and the base 100 are integrally formed.

[0024] The structure of the buckle 101 is as follows. It includes an elastic piece 1011 and a buckle head 1012. Among them, the elastic piece 1011 is directly integrally formed and connected to the base 100. The buckle head 1012 is located on the front of the head end of the elastic piece 1011. In order to facilitate the completion of the insertion, the buckle head 1012 is set as a wedge shape with a small top and a large bottom. Through the inclined surface of the wedge shape, when inserting, the elastic piece 1011 can be bent and deformed towards the back side, so that the buckle head 101 can cross the clamping hole 300 on the component 301 that needs to be matched, and then the elastic piece 1011 deforms and recovers to complete the clamping. In order to enhance the stiffness of the elastic piece 1011 and avoid the elastic piece 1011 from undergoing unexpected deformation due to external force after the clamping is completed and resulting in clamping failure, two vertical second reinforcing ribs 103 are provided on the back of the elastic piece 1011. The position and size of the second reinforcing ribs 103 should be determined according to the material and application requirements of the unilateral card.

[0025] The structure of the positioning post 102 is as follows. It includes a plate body, and the plate body is directly integrally formed and connected to the base 100. The plate body has two intersecting planes, namely the first surface 1021 and the second surface 1022. These two intersecting planes are set according to the positioning position to be achieved, constituting the positioning surfaces of the positioning post 102. After the unilateral card with positioning is clamped to the component 301 with the clamping hole 300, these two positioning surfaces cooperate with the two intersecting hole walls of the clamping hole 300 to achieve positioning. Since the buckle 101 and the positioning post 102 are separated from each other, the deformation of the buckle 101 during the clamping process will not affect the position of the positioning post 102, thus ensuring the positioning effect.

[0026] Since it is not desired that the positioning post 102 is deformed, in this embodiment, a first reinforcing rib 104 in the vertical direction is provided on the back surface of the positioning post 102 to improve the stiffness of the positioning post 102 and ensure accurate and reliable positioning. In addition, a support plate 105 is provided on the front surface of the positioning post. Support bosses 106 are formed on both the support plate 105 and the first reinforcing rib 104. The top surfaces of the support bosses 106 and the hook surface of the buckle 101 (i.e., the bottom of the wedge-shaped buckle head 1012) respectively abut against the front and back surfaces of the component 301 where the latching hole 300 is located, thereby making the latching firm. In this embodiment, the rear side surface 1041 of the first reinforcing rib 104 is also used to cooperate with the latching hole 300 for positioning.

[0027] As described above, the single-sided buckle with positioning in this embodiment can achieve the positioning function while latching, and the height of the positioning post 102 and the buckle 101 after passing through the latching hole 300 can be controlled at about 6 or 7 mm, which is the same as that of the ordinary single-sided buckle in the prior art, meeting the requirement for the space height.

[0028] Embodiment 2, please refer to Figure 7 、 Figure 8 As shown, the single-sided buckle with positioning in this embodiment is different from that in Embodiment 1 in the structure of the positioning post. In this embodiment, the plate body of the positioning post 202 is perpendicular to the base 200, and a support boss 203 that cooperates with the hook surface of the buckle 201 (i.e., the bottom of the wedge-shaped buckle head) is provided at the lower part of the plate body of the positioning post 202. The first reinforcing rib 204 of the positioning post 202 located on the left side of the buckle 201 is provided on the left side of the positioning post 202, and the first reinforcing rib 204 of the positioning post located on the right side of the buckle 201 is provided on the right side of the positioning post 202. At the same time, two intersecting positioning surfaces are formed by the side surface 2041 of the first reinforcing rib 204 and the front and rear side surfaces 2021 of the positioning post 202 to cooperate with the hole wall of the latching hole 300 for positioning.
