Description

Technical Field

[0001] This utility model relates to the field of airbag technology, and in particular to a universal, foolproof plastic buckle. Background Technology

[0002] The airbag buckle is a crucial component for the airbag's operation, as shown in the attached image. Figure 1 The image shows a snap-fit ​​structure currently used by the applicant. During design and use, the applicant discovered that the sheet metal mounting position and the plastic part mounting position are not on the central axis, and the short limiting hook has an irregular, asymmetrical structure, resulting in uneven stress. The mounting surface requires a separately designed foolproof structure. In traditional airbag snap-fit ​​designs, foolproof structures are often designed separately for different airbag models or vehicle models. This not only increases design and development costs but also complicates production and management. Moreover, during assembly, if the foolproof structure is not designed properly, assembly errors can still easily occur, causing the airbag to malfunction and posing a safety hazard. Utility Model Content

[0004] To achieve the above objectives, this utility model provides a universal foolproof plastic buckle, including a buckle body, which is composed of a sheet metal mounting part and a limiting hook part, wherein the limiting hook part is integrated with the sheet metal mounting part through a connecting part.

[0005] A slot is provided on the insertion part of the sheet metal mounting part on the side away from the limiting hook part, and a matching buckle is provided on both sides of the slot, and a limiting plate is provided below the matching buckle;

[0006] The mounting surface on the sheet metal mounting part is symmetrical and has a notch, and the sheet metal mounting position and the plastic part mounting position are on the central axis of the buckle body.

A slot is provided on the insertion part of the sheet metal mounting part away from the limiting hook part. Matching buckles are provided on both sides of the slot. A limiting plate is provided below the matching buckles. The mounting surface on the sheet metal mounting part is symmetrical and has notches. The sheet metal mounting position and the plastic part mounting position are on the central axis of the buckle body. The limiting hook part has a symmetrical structure. In this application, the sheet metal mounting position and the plastic part mounting position are on the central axis, resulting in more uniform force distribution and higher strength.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] like Figure 2 and Figure 3 As shown, where Figure 2 This is a schematic diagram of the overall structure of a universal, foolproof plastic clip. Figure 3This is a schematic diagram showing the location of notch 110. This utility model provides a universal, foolproof plastic buckle: including a buckle body 101, a sheet metal mounting part 102, a limiting hook part 103, a connecting part 104, a plug-in part 105, a slot 106, a mating buckle 107, a limiting disc 108, a mounting surface 109, a notch 110, a first mating hook 1031, a second mating hook 1032, a weight-reducing structure 111, an inclined structure 112, and a guide structure 113. The aforementioned solution eliminates the need for foolproof design during assembly, significantly improving assembly efficiency and saving costs, while simultaneously achieving better versatility and strength. It is understood that the aforementioned solution eliminates the need for foolproof design, offers high versatility, has a low design error rate, eliminates the need for foolproof assembly, improves assembly efficiency, saves costs, and provides high strength.

[0020] In this embodiment, the buckle body 101 consists of a sheet metal mounting part 102 and a limiting hook part 103. The limiting hook part 103 forms an integral structure with the sheet metal mounting part 102 through a connecting part 104. The integral structure can also directly achieve a significant increase in strength. The top part of the buckle body 101 is the core functional area of ​​the entire airbag buckle. Its shape is designed as a specific block structure, namely the insertion part 105, which has a notch 110 for limiting. The design of this notch 110 is the key to the buckle's foolproof function. It can cooperate with specific parts of the airbag and related components to ensure that the buckle is installed in the correct position and direction. The buckle body 101 is usually made of plastic with a certain strength and elasticity, which can ensure that it can be smoothly inserted into the corresponding position during assembly and can withstand a certain amount of external force during vehicle use without being easily damaged. The connecting part 104 usually has a certain thickness and strength to ensure the stability of the entire buckle. This section may be designed with reinforcing ribs or raised structures to further enhance its mechanical properties and prevent deformation or breakage during assembly and use. The design of the connection structure must also ensure that the sheet metal mounting position and the plastic part mounting position are on the central axis; this design guarantees the accuracy and stability of installation.

[0021] The sheet metal mounting part 102 has a slot 106 on the insertion part 105 on the side away from the limiting hook part 103. The slot 106 has a matching buckle 107 on both sides, and a limiting plate 108 is provided below the matching buckle 107. The slot 106 on the insertion part 105 is used for component insertion and matching, and the matching buckle 107 on both sides is used for fastening and matching during component installation to achieve stable connection and fixation with the connecting component. The limiting plate 108 is used for installation matching.

[0022] The mounting surface 109 on the sheet metal mounting part 102 is symmetrical and has a notch 110. The sheet metal mounting position and the plastic part mounting position are on the central axis of the buckle body 101. The symmetrical structure of the mounting surface 109 and the structure with the notch 110 make it possible to eliminate the need for a separate error prevention structure, thereby achieving a low error rate during design.

[0023] The limiting hook 103 has a symmetrical structure. This structure facilitates uniform force distribution, resulting in better force distribution compared to the irregular and asymmetrical structures in existing technologies. The symmetrically distributed limiting hooks 103 are crucial components for securing the buckle to the mounting base (such as vehicle body panels). The symmetrical design allows for even force distribution when the limiting hooks 103 are subjected to force, preventing buckle loosening or damage due to uneven force distribution. The shapes and dimensions of the first mating hook 1031 and the second mating hook 1032 are precisely designed to tightly fit with the corresponding holes or grooves on the mounting base, achieving reliable fixation. Their material is similar to the buckle body 101 described above, possessing good strength and toughness.

[0024] Secondly, the limiting hook 103 includes a first mating hook 1031 and a second mating hook 1032, which are symmetrically arranged. Both the first mating hook 1031 and the second mating hook 1032 are short hook structures, and their symmetrical arrangement facilitates even force distribution.

[0025] Then, a weight-reducing structure 111 is provided on the connecting part 104, and the weight-reducing structure 111 is symmetrically arranged. The weight-reducing structure 111 facilitates a certain degree of lightweight design of the buckle body 101, and is provided on the connecting part 104 as a U-shaped cavity structure.

[0026] Furthermore, the limiting plate 108 is provided with an inclined structure 112 on the side facing the mating buckle 107. The inclined structure 112 is used for a close fit during the installation of the corresponding connecting components.

[0027] Finally, a guide structure 113 is symmetrically provided on the top of the plug-in portion 105. The guide structure 113 is used to ensure better alignment and insertion of the plug-in portion 105 with the connecting component.

[0028] When using this utility model, no error-proofing design is needed during assembly, greatly improving assembly efficiency, saving costs, and simultaneously achieving better versatility and strength. Firstly, the buckle body 101 is composed of a sheet metal mounting part 102, a limiting hook part 103, and a connecting part 104 forming an integral structure. Then, a slot 106 is provided on the insertion part 105 of the sheet metal mounting part 102 on the side away from the limiting hook part 103. Matching buckles 107 are provided on both sides of the slot 106. The matching buckles 107 are used for fastening during component installation, achieving a stable connection and fixation with the connecting component. A limiting plate 108 is provided below the matching buckles 107. The mounting surface 109 on the sheet metal mounting part 102 is symmetrical and has a notch 110. The mounting surface 109 itself is symmetrical. The structure of the notch 110 eliminates the need for a separate error-proofing structure, thus achieving a low error rate during design. Furthermore, the sheet metal mounting position and the plastic part mounting position are on the central axis of the buckle body 101. The limiting hook 103 has a symmetrical structure, consisting of the first mating hook 1031 and the second mating hook 1032, both of which are short hook structures. This symmetrical arrangement facilitates uniform force distribution. In this application, the sheet metal mounting position and the plastic part mounting position are on the central axis, resulting in more uniform force distribution and higher strength. By symmetrically setting the notch 110 on the mounting surface 109 for limiting, a separate error-proofing structure is unnecessary, reducing the design error rate. This allows for assembly without considering error-proofing design, significantly improving assembly efficiency, saving costs, and simultaneously achieving better versatility and strength.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
