DETAILED DESCRIPTION

[0031] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0033] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprises" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0034] like Figures 1 to 3 As shown, the present application provides a snap-on structure 100, wherein the snap-on structure 100 includes a wire-holding portion 1, a positioning portion 2 and a connecting portion 3; the wire-holding portion 1 is used to fix the wiring harness, the positioning portion 2 is used to realize the connection between the snap-on and the mounting base, one end of the connecting portion 3 is connected to the wire-holding portion 1, and the other end of the connecting portion 3 is connected to the positioning portion 2 to form a complete snap-on structure 100. When used in a bumpy and vibrating environment, the snap-on structure 100 can provide support for the suspended position of the wiring harness to prevent the wiring harness from swinging greatly and colliding with surrounding components, causing noise or loosening of the wiring harness.

[0035] At least a portion of the connecting part 3 is an elastic connecting section 31, which can swing and deform. When used in a bumpy and vibrating environment, the wire holding part 1 can be displaced relative to the positioning part 2 when vibrated and drive the elastic connecting section 31 to elastically deform. In this way, through the elastic deformation of the elastic connecting part 3, the vibration amplitude and frequency of the wire holding part 1 and the wiring harness connected thereto can be closer to the vibration amplitude and frequency of the connecting part 3, thereby reducing the abnormal noise generated between the wiring harness and the connecting part 3 due to resonance.

[0036] like Figures 1 to 3As shown, the buckle structure 100 provided by the present application, wherein the connecting portion 3 is a columnar structure, and the connecting portion 3 also includes a first connecting segment 32 and a second connecting segment 33, wherein the first connecting segment 32 is connected to one end of the elastic connecting segment 31 and connected to the clamping portion 1, and the second connecting segment 33 is connected to the other end of the elastic connecting segment 31 and connected to the positioning portion 2. The first connecting segment 32 and the second connecting segment 33 are both made of non-elastic materials, that is, rigid materials or hard materials, and the elastic connecting segment 31 is made of elastic materials such as rubber or silicone. In a bumpy and vibrating environment, the elastic connecting segment 31 can be elastically deformed when subjected to external force, while the first connecting segment 32 and the second connecting segment 33 can only be displaced with the elastic deformation of the elastic connecting segment 31 and cannot be deformed, so as to ensure the connection reliability between the first connecting segment 32 and the clamping portion 1 and between the second connecting segment 33 and the positioning portion 2.

[0037] The buckle structure 100 provided in the present application has the first connecting section 32 and the second connecting section 33 having the same size along the axial direction of the connecting portion having a columnar structure, so as to ensure that the forces on the first connecting section 32 and the second connecting section 33 are roughly balanced in a bumpy and vibrating environment.

[0038] The buckle structure 100 provided in the present application, wherein, along the axial direction of the connecting portion with a columnar structure, the ratio of the size of the elastic connecting segment 31 to the size of the connecting portion 3 is in the range of 1 / 2 to 2 / 3, so as to disperse the force applied to various parts of the elastic connecting segment 31 during the deformation process and ensure the service life of the elastic connecting segment 31.

[0039] like Figures 1 to 4 As shown, the snap-fit ​​structure 100 provided in the present application has a plurality of reinforcing ribs 34 evenly spaced along the circumference on the outer peripheral surface of the connecting portion 3, and each reinforcing rib 34 extends along the axial direction of the connecting portion having a columnar structure, so as to enhance the structural strength of the elastic connecting segment 31, increase the force required for deformation of the elastic connecting segment 31, and control the deformation amplitude of the elastic connecting segment 31.

[0040] The dimension of the reinforcing rib 34 along the circumferential direction of the connecting portion 3 is greater than or equal to 2 mm to ensure the effect of enhancing the structural strength of the entire connecting portion 3 .

[0041] like Figures 1 to 6As shown, the snap-on structure 100 provided by the present application, wherein the reinforcing rib 34 and the elastic connecting section 31, the reinforcing rib 34 and the first connecting section 32, and the reinforcing rib 34 and the second connecting section 33 are all integrally formed and connected, that is, the reinforcing rib 34 is divided into three connected sections, the portion connected to the elastic connecting section 31 is made of elastic material as the elastic connecting section 31, and the portion connected to the first connecting section 32 and the second connecting section 33 is made of non-elastic material as the first connecting section 32 and the second connecting section 33, so as to ensure the connection strength between the reinforcing rib 34 and the first connecting section 32, the reinforcing rib 34 and the elastic connecting section 31, and the reinforcing rib 34 and the second connecting section 33.

[0042] Alternatively, if Figures 1 to 3 and Figure 6 As shown, the buckle structure 100 provided by the present application, wherein the wire clamping part 1 includes a clamping ring 11 with an opening on one side, and the clamping ring 11 is connected to the end of the first connecting section 32 away from the elastic connecting section 31; a wire clamping groove is formed on the inner side of the clamping ring 11 to accommodate and fix the wire harness, and the opening forms a notch of the wire clamping groove for the wire harness to be placed into or taken out of the wire clamping groove along it, and the size of the notch is smaller than the inner diameter of the clamping ring 11 to ensure the positioning effect of the wire clamping groove on the wire harness and prevent the wire harness from escaping from the wire clamping groove through the opening when it is unnecessary.

[0043] like Figure 6 As shown, the buckle structure 100 provided by the present application, wherein the wire clamping part 1 also includes two guide members 12, the two guide members 12 are connected to the clamping ring 11 and are located on both sides of the opening, and along the direction of the opening, the distance between the two guide members 12 gradually increases. By arranging the guide members 12, the wire harness can be guided in the process of entering the wire clamping groove, thereby reducing the difficulty of matching between the wire harness and the wire clamping part 1, and at the same time preventing the wire clamping part 1 from being damaged due to uneven force when contacting the clamping ring 11 at the opening.

[0044] like Figure 6 As shown, the buckle structure 100 provided in the present application has an anti-slip protrusion 111 formed on the inner surface of the clamping ring 11 to increase the friction between the wiring harness and the clamping ring 11, further preventing the wiring harness from escaping from the wire clamping groove through the opening or moving along its axial direction when unnecessary.

[0045] like Figures 1 to 3 and Figure 6As shown, the buckle structure 100 provided by the present application, wherein the positioning portion 2 includes a positioning hook 21 and a positioning ring piece 22, the positioning hook 21 and the positioning ring piece 22 are both connected to the end of the second connecting section 33 away from the elastic connecting section 31, and a positioning gap is formed between the positioning hook 21 and the positioning ring piece 22. The positioning portion 2 is mainly adapted to the mounting base of the plate-like structure. During assembly, the positioning hook 21 penetrates the mounting base, so that the positioning hook 21 and the positioning ring piece 22 are respectively located on both sides of the plate-like structure, and the plate-like structure is positioned and clamped in the positioning gap between the positioning ring piece 22 and the positioning hook 21, so that the positioning connection between the buckle structure 100 and the mounting base is completed.

[0046] like Figure 6 As shown, the buckle structure 100 provided by the present application, wherein the positioning hook 21 includes a central rod 211 and a plurality of claws 212, the first end of the central rod 211 is fixedly connected to the second connecting section 33, and each claw 212 is fixedly connected to the second end of the central rod 211 and is arranged at intervals along the circumference of the central rod 211, so as to ensure that each claw 212 is evenly stressed when cooperating with the mounting base, and to ensure the overall service life of the positioning hook 21. And each claw 212 extends from the second end of the central rod 211 to the first end of the central rod 211, so as to be positioned by abutting against a side surface of the mounting base with a plate-like structure through the end of each claw 212 close to the first end of the central rod 211. Along the direction from the second end of the center rod 211 to the first end of the center rod 211, the distance between each claw portion 212 and the center rod 211 gradually increases, and a mounting hole is opened on the mounting base, and the aperture of the mounting hole is smaller than the maximum radial dimension of the positioning hook 21 along the mounting hole. When the positioning hook 21 passes through the mounting hole, each claw portion 212 elastically deforms in the direction close to the center rod 211 to move closer to each other, so that the maximum radial dimension of the positioning hook 21 along the mounting hole is reduced. After each claw portion 212 with the positioning hook 21 successfully passes through the mounting base, each claw portion 212 is no longer subjected to the radial force of the mounting hole, and each claw portion 212 returns to its original state under the action of its own elastic restoring force, and the radial dimension of each claw portion 212 along the mounting hole is increased again to be larger than the aperture diameter of the mounting hole, and the end portion of each claw portion 212 close to the first end of the center rod 211 abuts against the surface of the mounting base. At this time, the positioning hook 21 cannot escape from the positioning hole, thereby effectively ensuring the positioning effect of the positioning hook 21.

[0047] like Figure 6As shown, the buckle structure 100 provided by the present application, wherein the positioning ring piece 22 is a conical cylindrical structure with a diameter gradually increasing along the direction from the second connecting section 33 to the positioning hook claw 21, and the end of each claw portion 212 close to the first end of the center rod 211 extends into the interior of the conical cylindrical structure, and a positioning gap is formed between the end of each claw portion 212 close to the first end of the center rod 211 and the inner surface of the positioning ring piece 22. In this way, when the mounting base is clamped in the positioning gap, each claw portion 212 of the positioning hook claw 21 abuts against one side surface of the mounting base, and the outer edge of the positioning ring piece 22 abuts against the other side surface of the mounting base. In this way, the positioning hook claw 21 cooperates with the positioning ring piece 22 to effectively realize the positioning connection between the positioning portion 2 and the mounting base.

[0048] like Figure 7 and Figure 8 As shown, the present application also provides a vehicle, wherein the vehicle comprises:

[0049] The mounting base 200 is provided with mounting holes; the mounting base 200 may be a base plate of a motor, a bottom plate of a battery pack, a door panel or other structures.

[0050] The wiring harness 300 is arranged on one side of the installation base 200 . The wiring harness 300 may be a linear structure such as an electric wire or a window lifter pull cord.

[0051] As for the buckle structure 100 as described above, the positioning portion 2 of the buckle structure 100 is positioned and clamped in the mounting hole, and the wire harness 300 is positioned and clamped in the wire clamping portion 1 to achieve positioning between the wire harness 300 and the mounting base 200 .

[0052] The vehicle provided in the embodiment of the present application uses a positioning buckle, which can realize the positioning and installation of the buckle structure 100 on the basic component by setting the positioning part 2, and can position the wire harness by setting the wire clamping part 1. When used in a bumpy and vibrating environment, it can provide support for the suspended wire harness to prevent the wire harness from swinging greatly and colliding with surrounding components to cause noise or loose wire harness; at the same time, the positioning part 2 is connected to the wire clamping part 1 by setting an elastic connecting part 3. When used in a bumpy and vibrating environment, the elastic deformation of the elastic connecting part 3 can make the vibration amplitude and frequency of the wire harness and the connecting part 3 closer, thereby reducing the abnormal noise generated between the wire harness and the connecting part 3 due to resonance.
