[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0025] The terms "include" and "have" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0026] The present application will be further described below in conjunction with the drawings:

[0027] As Figures 1 to 5As shown, the application provides a car door panel buckle, comprising a first buckle body 1 and a second buckle body 2, a plurality of clamping arms 11 are arranged on the first end of the first buckle body 1 along the circumference and towards the second end of the first buckle body 1, the first buckle body 1 is suitable for hole clamping through the clamping arms 11, the first buckle body 1 and the second buckle body 2 are suitable for mutual connection and form a clamping structure between them, so as to realize the clamping of two different objects.

[0028] The end of the clamping arm 11 is inwardly bent towards the first buckle body 1 and cooperates with the first buckle body 1 to form a deformation chamber 12, the deformation chamber 12 is suitable for accommodating the support ring 3, the first end of the clamping arm 11 is suitable for forming a tapered structure to realize the combination with the hole, the clamping arm 11 can realize the disengagement with the hole through the inwardly bent structure, and repeated disassembly and assembly can be realized.

[0029] As shown in the embodiments of Figure 1 and 3 , the clamping arms 11 are distributed equidistantly along the circumference of the first buckle body 1, which can disperse the stress and improve the connection strength and stability between the first buckle body 1 and the hole.

[0030] The second buckle body 2 is provided with a positioning arm 21, the second buckle body 2 is suitable for being connected with the second end of the first buckle body 1 through the positioning arm 21, the positioning arm 21 is suitable for extending into the deformation chamber 12 through the second end of the first buckle body 1, so that the support ring 3 is limited between the clamping arm 11 and the first buckle body 1, the positioning arm 21 can help the support ring 3 to be positioned in the deformation chamber 12, so that the support ring 3 can obtain more stable support effect, and the support ring 3 can limit the deformation of the positioning arm 21 towards the first buckle body 1 by filling the gap between the first buckle body 1 and the positioning arm 21 in the deformation chamber 12, thereby improving the connection strength and stability between the positioning arm 21 and the hole.

[0031] As shown in the embodiments of Figure 2 and 4 , the positioning arm 21 limits the support ring 3 between the root of the clamping arm 11 and the first buckle body 1 in the deformation chamber 12, it can be understood that the root of the clamping arm 11 can have a smaller deformation amplitude, so that the end of the clamping arm 11 has a larger deformation amplitude, therefore, the support ring 3 can effectively reduce the upper limit of the deformation amplitude of the end of the clamping arm 11 by supporting between the root of the clamping arm 11 and the first buckle body 1, thereby improving the strength and stability of the clamping of the first buckle body 1 with the hole through the clamping arm 11, in addition, if the support ring 3 is limited between the end of the clamping arm 11 and the first buckle body 1, the upper limit of the deformation amplitude of the end of the clamping arm 11 will be limited too small, which will easily cause the first buckle body 1 to be difficult to be repeatedly disassembled and assembled while ensuring that the positioning arm 21 is not damaged, therefore, it is a more appropriate solution to limit the deformation of the root of the clamping arm 11 by the support ring 3.

[0032] In some embodiments, in order to facilitate the installation of the support ring 3 onto the first buckle body 1, the support ring 3 is configured to be elastic, so that the support ring 3 can expand and be inserted from the first end or the second end of the first buckle body 1, so as to move to the entrance of the deformation chamber 12 and enter the deformation chamber 12.

[0033] It is understandable that since the supporting function of the support ring 3 is achieved through the second buckle 2, disassembling it in the order of first removing the second buckle 2 and then removing the first buckle 1 can relieve the supporting function of the support ring 3, thereby further reducing the probability of damage to the snap-fit ​​arm 11 and achieving higher reusability.

[0034] like Figures 1 to 5 In the illustrated embodiment, a first limiting plate 13 is provided at the second end of the first buckle body 1. The first limiting plate 13 is used to restrict the first buckle body 1 from passing through the hole and can cooperate with the snap-fit ​​arm 11 to snap on both sides of the hole. The ends of the first limiting plate 13 and the snap-fit ​​arm 11, as well as the end of the snap-fit ​​arm 11 and the second buckle body 2, are adapted to form an installation channel for the support ring 3 to pass through, so that the support ring 3 can be installed on the first buckle body 1 from the outside. Specifically, the minimum gap between the first limiting plate 13 and the snap-fit ​​arm 11 can be set to be no less than the diameter of the support ring 3, and the minimum gap between the end of the snap-fit ​​arm 11 and the second buckle body 2 can be set to be no less than the diameter of the support ring 3.

[0035] like Figure 2 In the embodiment shown, an abutment surface 111 is provided on the outer side of the end of the snap-fit ​​arm 11. An included angle α is formed between the abutment surface 111 and the first limiting plate 13, where 30°≤α<45°. By optimizing the angle of the abutment surface 111, the snap-fit ​​stability between the end of the snap-fit ​​arm 11 and the hole can be improved, and the snap-fit ​​arm 11 can be disengaged from the hole after being subjected to a certain external force, so that the first buckle body 1 can be repeatedly disassembled and reassembled.

[0036] like Figures 1 to 5 In the embodiment shown, a second limiting plate 22 is provided at the end of the second buckle 2 away from the snap-fit ​​arm 11. When the first buckle 1 and the second buckle 2 are connected, the first limiting plate 13 and the second limiting plate 22 are parallel to each other. The second limiting plate 22 is suitable for restricting the second buckle 2 from passing through the hole or object, and can cooperate with the first buckle 1 to make a more stable snap-fit. At the same time, it can increase the force-bearing area and facilitate pressing the second buckle 2 and the first buckle 1 together.

[0037] like Figures 1 to 4In the shown embodiment, the first buckle body 1 and the second buckle body 2 are combined with each other along the axial direction, the positioning arm 21 extends along the axial direction of the second buckle body 2, the second end of the first buckle body 1 is provided with a positioning channel 14 along the axial direction, the positioning channel 14 is suitable for the positioning arm 21 to pass through, and the first buckle body 1 and the second buckle body 2 are suitable for being combined with each other through the cooperation of the positioning channel 14 and the positioning arm 21, which can effectively reduce the difficulty of installation and pairing.

[0038] The number of the positioning channel 14 and the positioning arm 21 is the same and multiple, the positioning channel 14 is distributed along the circumference of the first buckle body 1, and the positioning arm 21 is distributed along the circumference of the second buckle body 2, and it can be understood that the more the number of the positioning channel 14 and the positioning arm 21 is, the higher the combination strength of the first buckle body 1 and the second buckle body 2 is.

[0039] In some embodiments, the number of the positioning channel 14 and the positioning arm 21 is the same and multiple, and the positioning channel 14 and the positioning arm 21 are equally spaced along the circumference of the second buckle body 2, which can bear force uniformly and improve the structural strength and stability of the second buckle body 2.

[0040] As shown in the embodiments of Figure 1 and 2 , the outer side of the clamping arm 11 is provided with a clamping tooth, the clamping tooth is suitable for being clamped with the side wall of the positioning channel 14 to limit the first buckle body 1 and the second buckle body 2 from moving away from each other, the clamping tooth can realize stepless combination of the first buckle body 1 and the second buckle body 2, and the clamping structure between the first buckle body 1 and the second buckle body 2 can adapt to objects with different thicknesses.

[0041] As shown in the embodiments of Figure 3 and 5 , the second buckle body 2 extends a connecting arm 23 along the axial direction, the first buckle body 1 is provided with a connecting hole 15, and the connecting arm 23 is suitable for being clamped with the connecting hole 15 to limit the first buckle body 1 and the second buckle body 2 from moving away from each other, the clamping structure of the connecting arm 23 and the connecting hole 15 can assist the positioning of the positioning arm 21, when the connecting arm 23 and the connecting hole 15 are combined, the positioning arm 21 reaches the specified position to limit the support ring 3, and at the same time, the positioning arm 21 and the positioning channel 14 can assist the positioning of the connecting arm 23 and the connecting hole 15 in the circumferential direction of the first buckle body 1, thereby ensuring that the connecting arm 23 and the connecting hole 15 can be combined smoothly.

[0042] As shown in the embodiments of Figure 3 and 5 , the first buckle body 1 is provided with a connecting channel 16 at the axial center, the connecting hole 15 is arranged in the connecting channel 16, and the connecting arm 23 is suitable for entering the connecting hole 15 from the connecting channel 16 to be clamped, and by arranging the connecting channel 16 at the axial center of the first buckle body 1, the weight of the first buckle body 1 can be reduced without affecting the structural strength of the first buckle body 1, thereby realizing lightweight.
