Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a snap-fit ​​structure and a bracket equipped with the structure. Background Technology

[0002] In the automotive manufacturing industry, with the continuous increase in demand for lightweight and efficient assembly, the integrated design of structural components and connectors is gradually becoming an industry trend. Traditionally, separate brackets and clips are used for connection. These clips are usually assembled onto the bracket after it has been formed, using manual or automated equipment, to achieve a fixed connection with the vehicle body or motor.

[0003] However, this assembly method has some problems:

[0004] (a) The post-assembly process of the snap-on plastic bracket increases the manufacturing steps and assembly time, which in turn affects production efficiency;

[0005] (ii) Because the structure of the buckle is usually quite complex and requires high-precision positioning, installation deviations are prone to occur during the assembly process, which affects the stability of the overall connection.

[0006] (iii) In the logistics and transportation of traditional products, the clip is easily subjected to external forces, which may cause it to loosen or become skewed.

[0007] To address these issues, some technical solutions attempt to pre-embed or directly integrate the snap-fit ​​into the bracket structure to reduce subsequent assembly steps. However, in actual molding, the complex shape of the snap-fit ​​structure and issues such as undercut structures during demolding can lead to difficulties in demolding, part deformation, and even mold damage during the injection molding demolding stage. Furthermore, in the subsequent foaming process, the integrated snap-fit ​​bracket also needs to consider the sealing performance with the foaming mold. Because polyurethane foam is a liquid raw material, during production, the liquid material can easily seep into the snap-fit ​​position through the gap between the bracket and the foaming mold, causing contamination of the snap-fit ​​and ultimately resulting in snap-fit ​​malfunction. Utility Model Content

[0008] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a snap-fit ​​structure and a bracket equipped with the structure to solve one or more problems in the prior art.

[0009] To achieve the above objectives, the technical solution of this utility model is as follows:

[0010] A snap-fit ​​structure includes a connector, with a positioning part connected to one end and a connecting part connected to the other end along the length direction of the connector; the structure also includes a locking body, which is arranged along the length direction of the connector and is connected to the surface of the connector at one end.

[0011] Furthermore, the positioning part includes a guide and an insertion body, with one end of the guide connected to the connecting body and the other end connected to the insertion body.

[0012] Furthermore, the intruding body extends in a cone shape away from the connecting body.

[0013] Furthermore, the coupling body has an annular protrusion on its end face near the connector body.

[0014] Furthermore, the locking bodies are symmetrically arranged on both sides of the end face of the connector and are uniformly arranged along the length direction of the connector.

[0015] Furthermore, the heights of the locking bodies on both sides of the end face of the connector are staggered on the first plane.

[0016] Furthermore, the locking solid is disposed obliquely relative to the first plane, and is oriented from the surface of the connector toward the side of the joint.

[0017] Furthermore, the structure also includes anti-torsion bodies, which are uniformly disposed at the connection between the connector and the joint.

[0018] Furthermore, the anti-torsion body is simultaneously connected to both the connecting body and the coupling body.

[0019] A bracket is provided with the aforementioned snap-fit ​​structure, wherein the engaging part of the snap-fit ​​structure is integrally formed with the surface of the bracket.

[0020] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0021] (i) By staggering and obliquely setting the height of the locking solid on the connector, this new invention effectively ensures the firmness of the connection between the buckle and the bracket. Compared with the traditional complex buckle shape, it effectively solves the problem of the buckle forming a complex demolding direction or being unable to demold when reversed.

[0022] (ii) By providing a protrusion on the end face of the snap fastener, the intrusion of polyurethane liquid material after the snap fastener and bracket are assembled with the foam mold mounting hole is effectively prevented, thereby protecting the functionality of the snap fastener.

[0023] (iii) By uniformly distributing anti-torsion bodies at the junction of the joint and the connecting part, the anti-torsion effect of the buckle structure is improved, thus avoiding accidental breakage of the buckle during installation and removal. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the snap-fit ​​structure and the bracket equipped with the structure proposed by this utility model. The advantages and features of this utility model will become clearer according to the following description. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, used only to facilitate and clearly illustrate the purpose of the embodiments of this utility model. Please refer to the accompanying drawings to make the objectives, features, and advantages of this utility model more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only used to complement the content disclosed in the specification, for those skilled in the art to understand and read, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed in this utility model.

[0030] Please see Figures 1 to 4The snap-fit ​​structure shown in this embodiment includes a connecting body 1, which is preferably a cylinder in this embodiment. Preferably, the size of the connecting body 1 can be adaptively adjusted according to the inner diameter of the threaded hole in different embodiments. Different components are connected to both ends of the connecting body 1. Specifically, a positioning part 2 for positioning is connected to one end of the connecting body 1, and a connecting part 3 for engagement is connected to the other end of the connecting body 1. Furthermore, the structure also includes multiple locking bodies 4, which are arranged along the length of the connecting body 1, and one end of each locking body 4 is connected to the surface of the connecting body 1.

[0031] Furthermore, the positioning part 2 includes two parts: a guide body 21 and an insertion body 22. One end of the guide body 21 is connected to the connecting body 1, while the other end is connected to the insertion body 22, thus forming a continuous structure. The insertion body 22 is connected to the connecting body 1 and gradually forms a cone shape in the direction away from the connecting body 1. This design helps to ensure the insertion and positioning of the connecting body 1 during use.

[0032] Furthermore, the connecting body 3 has an annular protrusion 31 at the end face near the connecting body 1. The protrusion 31 is designed to enhance the stability and firmness during the connection. In this embodiment, the diameter of the protrusion 31 is set to be greater than the diameter of the threaded hole to be assembled, which effectively prevents the buckle and bracket from failing due to liquid material flowing into the assembly point of the buckle and the threaded hole during the process of cooperating with the foaming mold.

[0033] Furthermore, the locking solids 4 are symmetrically arranged on both sides of the end face of the connector 1 and evenly distributed along the length of the connector 1. Preferably, the locking solids 4 are made of a material with a certain degree of elasticity, which facilitates the assembly or removal of the buckle relative to the bracket. In this embodiment, the connector 1 is a cylinder, and the end face of the connector 1 is circular. That is, the locking solids 4 are correspondingly arranged at both ends of the diameter of the circle, thus ensuring the balance and reliability of the locking.

[0034] Furthermore, the locking bodies 4 on both sides of the end face of the connector 1 are arranged in a staggered pattern at their respective heights on the first plane. The locking bodies 4 are also obliquely positioned relative to the first plane, with the direction of inclination being from the surface of the connector 1 towards the coupling body 3, resembling a "cedar tree." This design helps improve the overall stability of the snap-fit ​​structure, effectively and tightly locking with the threaded hole, and also facilitating smooth demolding. In this embodiment, the first plane is the plane of the circular end face of the connector 1.

[0035] Furthermore, the structure also includes an anti-torsion body 5, which is uniformly disposed at the connection between the connector 1 and the joint 3, and is connected to both the connector 1 and the joint 3. This effectively enhances the anti-torsion effect at the connection between the connector 1 and the joint 3, preventing breakage failure due to excessive stress during buckle disassembly and installation.

[0036] In this embodiment, the bracket is equipped with the aforementioned snap-fit ​​structure. The engaging part 3 of the snap-fit ​​structure is integrally formed with the surface of the bracket. The integrated bracket and snap-fit ​​structure are then connected to the external motor mounting hole to achieve a secure fixation, improving the consistency and reliability of the overall components.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
