[0038] like Figures 1 to 6 As shown, an embodiment of the present application provides an automobile anti-drop buckle, including a buckle body 100 , a frame plate 200 , an elastic wedge block 300 and a matching plate 400 .

[0039] The buckle body 100 provides a mounting base for other components. For example, automobile interior parts are fixedly mounted on the buckle body 100 by welding, gluing, bolting or integral molding.

[0040] like Figure 2 As shown, the frame plate 200 is fixedly mounted on the buckle body 100 by welding, bolt connection, integral molding or gluing.

[0041] like Figure 2 As shown, the frame plate 200 is a rectangular frame structure with a hollow interior, and one end of the frame plate 200 is fixedly disposed on one end of the buckle body 100 .

[0042] like Figure 2 As shown, the frame plate 200 is arranged parallel to the buckle body 100, that is, the plane where the frame plate 200 is located is parallel to the plane where the buckle body 100 is located. Of course, there may be an angle between the frame plate 200 and the buckle body 100, for example, the frame plate 200 and the buckle body 100 are arranged vertically. It can be set according to actual needs and is not limited here.

[0043] like Figure 2 As shown, the frame plate 200 is hollow inside, so the frame plate 200 has an inner wall, the inner wall on one side of the inner wall of the frame plate 200 away from the buckle body 100 is the first inner wall 210, and the inner wall on one side of the inner wall of the frame plate 200 close to the buckle body 100 is the second inner wall 220. Exemplarily, the inner wall of the frame plate 200 can be divided into four sub-inner walls, one sub-inner wall is closer to the buckle body 100 than the other three inner walls, and this sub-inner wall is the second inner wall 220, and the sub-inner wall arranged opposite to the first inner wall 210 is the first inner wall 210. Among the four sub-inner walls, the other two sub-inner walls are respectively located on both sides of the first inner wall 210 and the second inner wall 220, and the two inner walls are arranged opposite to each other.

[0044] like Figure 2 As shown, the elastic wedge block 300 is a triangular prism block structure, and the elastic wedge block 300 has three edges, one of which is fixedly connected to the first inner wall 210, so that the elastic wedge block 300 is fixedly installed on the first inner wall 210. The elastic wedge block 300 has three side walls and two end walls, as shown in FIG. Figure 5 As shown, three side walls of the elastic wedge block 300 are arranged to be inclined with respect to each other, and one of the side walls is parallel to the frame plate 200 .

[0045] Exemplarily, the elastic wedge block 300 is fixedly connected to the frame plate 200 by gluing, welding or integral molding.

[0046] The elastic wedge block 300 is elastically connected to the frame plate 200, so that the elastic wedge block 300 can have a certain rebound amount A relative to the frame plate 200, such as Figure 5As shown, the ratio of the rebound amount A of the elastic wedge 300 to the maximum thickness B of the elastic wedge 300 is C, where 0.086≤C≤0.43. For example, if the maximum thickness B of the elastic wedge 300 is 3.472 mm and the rebound amount A of the elastic wedge 300 is 1.458 mm, the ratio C is 0.419.

[0047] like Figure 6 As shown, the mating plate 400 is provided with a mating hole 410; Figure 1 As shown, the frame plate 200 and the elastic wedge block 300 are inserted into the matching hole 410 of the matching plate 400 , and the elastic wedge block 300 prevents the frame plate 200 from slipping out of the matching hole 410 .

[0048] like Figure 4 and Figure 5 As shown, in one embodiment, the end surface of the elastic wedge 300 close to the second inner wall 220 is a first inclined surface 310, and the first inclined surface 310 is inclined at a first preset angle α relative to the second inner wall 220, wherein 0°<α≤45°. Exemplarily, α=15°. In another embodiment, α=30°. In another embodiment, α=45°.

[0049] During use, when the frame plate 200 is pulled out of the matching hole 410, the first inclined surface 310 of the elastic wedge block 300 will push the end surface of the matching hole 410 on the frame plate 200, and the end surface of the matching hole 410 on the frame plate 200 will generate a reaction force on the first inclined surface 310 of the elastic wedge block 300. After the reaction force acts on the first inclined surface 310, a component force will be generated to resist the force of pulling the frame plate 200 out of the matching hole 410. The smaller α is, the greater the component force is, and the difficulty of the frame plate 200 to escape from the matching hole 410 is increased, thereby improving the connection reliability of the anti-detachment buckle of the automobile. However, if α is too small, it will affect the frame plate and the elastic wedge block from being pulled out of the matching hole, affecting the disassembly and maintenance, so 0°<α≤45° is set.

[0050] like Figure 6 As shown, in one embodiment, a receiving groove 420 is provided on the inner wall of the matching hole 410 and is arranged parallel to the matching hole 410. The receiving groove 420 is located on the side of the matching hole 410 away from the protruding portion of the elastic wedge block 300. When the frame plate 200 needs to be installed into the matching hole 410 or pulled out from the matching hole 410, the inner wall of the matching hole 410 will push the elastic wedge block 300, so that the elastic wedge block 300 is deformed relative to the frame plate 200. After the elastic wedge block 300 is deformed, it enters the receiving groove 420. The receiving groove 420 provides a margin for the deformation amount of the elastic wedge block 300 during installation to prevent the wedge-shaped inclined block 300 from being blocked.

[0051] For example, Figure 6As shown, the length of the receiving groove 420 is smaller than the length of the matching hole 410 ; illustratively, the length of the receiving groove 420 is slightly larger than the edge length of the elastic wedge block 300 .

[0052] like Figure 2 , Figure 3 or Figure 4 As shown, in one embodiment, the automobile anti-detachment buckle also includes an anti-vibration block 600, which is fixedly mounted on the buckle body 100, and the anti-vibration block 600 and the frame plate 200 are located on the same side end surface of the buckle body 100, and the anti-vibration block 600 is arranged parallel to the frame plate 200. When the frame plate 200 and the elastic wedge block 300 are inserted into the matching hole 410 of the matching plate 400, the anti-vibration block 600 abuts against the end surface of the matching plate 400, and the anti-vibration block 600 pushes the matching plate 400 through the reaction force, so that the elastic wedge block 300 abuts against the end surface at the matching hole 410.

[0053] The anti-vibration block 600, as a buffer between the buckle body 100 and the mating plate 400, can absorb and disperse vibration energy during the driving of the car, reducing the direct impact of vibration on the buckle body 100 and the car interior decoration parts arranged on the buckle body 100. This helps to extend the service life of the car anti-slip buckle and the car interior decoration parts, and reduce damage or failure caused by vibration. Through the supporting effect of the anti-vibration block 600, the mating plate 400 is not easily displaced or deformed when subjected to vibration, thereby improving the stability and reliability of the entire car anti-slip buckle.

[0054] like Figure 2 As shown, in one embodiment, two anti-vibration blocks 600 are provided, one anti-vibration block 600 is provided on one side of the frame plate 200 , and the other anti-vibration block 600 is provided on the other side of the frame plate 200 .

[0055] The anti-vibration blocks 600 are symmetrically arranged on both sides of the frame plate 200, so that the reaction force of the matching plate 400 on the buckle body 100 is more uniform, and the frame plate 200 on the buckle body 100 is more stably connected in the matching hole 410, thereby enhancing the anti-slip effect and ensuring that the car's anti-slip buckle can remain stable under various vibration environments during the driving of the car.

[0056] In one embodiment, the thickness of the two anti-vibration blocks 600 may be the same or different, and may be set according to actual engineering needs.

[0057] In one embodiment, the anti-vibration block 600 is made of a flexible material to reduce vibration, thereby helping to extend the service life of the automobile anti-drop buckle and reduce damage or malfunction caused by vibration.

[0058] like Figure 4 As shown, in one embodiment, there is a gap between the elastic wedge 300 and the second inner wall 220 .

[0059] like Figure 4 As shown, in one embodiment, a rounded corner is provided on one end of the elastic wedge 300 away from the buckle body 100, which can effectively disperse the stress generated when the frame plate 200 is inserted into or removed from the matching hole 410. Compared with sharp corners, the rounded corner can provide a smoother transition, reduce the concentration of stress at the end of the frame plate 200, and thus reduce the risk of damage to the frame plate 200 or deformation of the matching hole 410.

[0060] like Figure 3 As shown, in one embodiment, a guiding inclined surface 230 is provided on an end surface of the frame plate 200 away from the protruding portion of the elastic wedge block 300 .

[0061] The guide slope 230 plays a guiding role when the frame plate 200 and the matching plate 400 are assembled by clamping. The guide slope 230 can guide the frame plate 200 to slide smoothly into a predetermined position along the slope, reduce resistance during assembly, and improve assembly efficiency. By setting the guide slope 230, it can be ensured that the frame plate 200 and the matching plate 400 can be accurately aligned during clamping assembly, avoiding assembly problems caused by position deviation.

[0062] like Figure 6 As shown, in one embodiment, the automobile anti-drop buckle further includes a first support plate 500 and a second support plate 550 .

[0063] The first support plate 500 is fixedly connected to the matching plate 400 , and the first support plate 500 and the matching plate 400 are vertically arranged.

[0064] The second support plate 550 is fixedly connected to the matching plate 400 and the first support plate 500. The first support plate 500, the second support plate 550 and the matching plate 400 are perpendicular to each other. The first support plate 500, the second support plate 550 and the matching plate 400 are arranged perpendicular to each other, which can provide the strength of the snap connection, prevent the matching plate 400 from excessive deformation, and improve the stability of the snap connection. Exemplarily, the second support plate 550, the matching plate 400 and the first support plate 500 are fixedly connected by welding, gluing or integral molding.

[0065] The matching plate 400 and the first support plate 500 and / or the second support plate 550 are fixedly arranged on the frame of the automobile. By strengthening the anti-deformation ability of the matching plate 400, a good installation foundation can be provided for the buckle body 100 and the frame plate 200. The entire automobile anti-drop buckle is more stable when subjected to dynamic loads such as vibration and impact, and is not easy to loosen or fall off, which helps to reduce the probability of failure of the automobile anti-drop buckle during use and prolong the service life. The mutually perpendicular first support plate 500, the second support plate 550 and the matching plate 400 make the entire automobile anti-drop buckle structure more compact and save installation space. This is particularly important for equipment with limited space such as automobiles.

[0066] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0067] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0068] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
