Description

Technical Field

[0001] This utility model belongs to the field of automotive fastener technology, specifically relating to a multi-directional strap buckle and automotive trim panel assembly structure. Background Technology

[0002] Automotive fasteners include various types such as bolts, nuts, screws, clips, cable ties, and pipe clamps; for example... Figure 1 As shown, a current automotive tie-down buckle 10' is illustrated, comprising a resilient buckle 11', a first tie 12', and a retaining disc 13'. A T-slot 21' is formed on the automotive trim panel 20', with an opening at one end. During installation, the first tie 12' and retaining disc 13' are first inserted into the T-slot 21' through the opening, with the resilient buckle 11' facing the direction of the automotive sheet metal part. Then, the resilient buckle 11' is inserted into the mounting hole of the automotive sheet metal part. Multiple tie-down buckles are then installed in the same manner to complete the connection and assembly between the automotive trim panel 20' and the automotive sheet metal part. While existing tie-down buckles can complete the installation of automotive trim panels, they often only provide unidirectional restraint. When force is applied in the direction of the opening of the T-slot 21', the first tie 12' and retaining disc 13' are prone to detaching outwards from the opening. Therefore, for special locations on a car, it is necessary to consider both the directionality during installation and the multi-directional impact force during airbag deployment. For example, in the narrow space of the seat belt fixing shell, it is impossible to install in the axial direction of the hole. It can only be installed by sliding from top to bottom. In this way, traditional strap buckles cannot provide the pulling force in the sliding installation direction of the trim panel during the explosion, causing the trim panel to fly out in this direction, injuring the driver and passengers. Therefore, current strap buckle products cannot meet the requirements. Summary of the Invention

[0003] The purpose of this utility model is to provide a multi-directional fastener and automotive trim assembly structure, which aims to solve the problem that the existing fastener cannot be installed in the axial direction of the hole and can only be inserted by sliding from top to bottom, resulting in insufficient reliability.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: A multi-directional strap buckle includes a first strap, one end of which is provided with a buckle and the other end of which is provided with a limiting disc. A second strap extends from the outer periphery of the limiting disc and is perpendicular to the first strap. A limiting portion is provided on the second strap at the end away from the limiting disc.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the connection end between the limiting part and the second tether has an enlarged part.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the end of the limiting part away from the second tether has an inclined surface or a conical surface.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the multi-directional lacing buckle is an integral structure.

[0008] Based on the above scheme and as the preferred option, the multi-directional fastener is integrally injection molded.

[0009] In addition, an automotive trim panel assembly structure is disclosed, including a multi-directional strap buckle, which has a first slot on a first surface of the automotive trim panel, the first strap and the limiting disc being embedded in the first slot; on the automotive trim panel, a second slot is formed on a second surface perpendicular to the first surface, the second strap passes through the second slot, and the limiting portion extends outward from the second slot.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the second slot includes a first slot and a second slot that are connected to each other. The width of the first slot is greater than the maximum width of the limiting part and is also greater than the width of the second slot. The width of the second slot is less than the maximum width of the limiting part.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the second groove is located at the end of the second groove that is away from the limiting plate.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: the end of the first card slot away from the second card slot is provided with an opening.

[0013] Based on the above scheme and as a preferred embodiment of the above scheme: the opening is a wide-mouth structure.

[0014] The outstanding and beneficial technical effects of this utility model compared with the prior art are as follows: by setting a second strap structure on the limiting plate, the limiting part of the head and the sliding groove of the automotive trim form a constraint. The second strap and the limiting part exert a large pulling force on the automotive trim, ensuring that the trim cover will not fly out and injure people at will. Moreover, it can be installed in a narrow range, and can provide a product with a large pulling force in both the sliding direction and the axis of the mounting hole. It also takes into account the ejection direction of the injection mold of the snap-on product and the production convenience of opening mounting holes on the customer's housing.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the given embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Example

[0018] See details Figure 2-7As shown, this application discloses a multi-directional strap buckle, including a first strap 12, one end of which is provided with a buckle 11, and the other end is provided with a limiting disc 13. The buckle 11 includes a body 111 and a sealing body 112, wherein the body 111 includes a guide section, a limiting section, and a connecting section with a conical, curved, or spherical surface. The guide section facilitates the centering of the buckle 11 and allows it to be inserted more smoothly into the automotive mounting hole during pressure application. The diameter of the limiting section is larger than the diameter of the automotive mounting hole. During the insertion process, the limiting section undergoes elastic deformation to allow it to enter or pass through the automotive mounting hole. After passing through, it will restore its shape on the other side of the sheet metal part, thereby restricting the buckle 11 and preventing it from falling out of the automotive mounting hole, thus achieving the connection between the head and the automotive mounting hole. The sealing body 112 is skirt-shaped or bowl-shaped, with its root sealed to the body 111. The opening faces the side where the body 111 is located and is larger than the car mounting hole. When the buckle 11 is inserted into the car mounting hole, the opening of the sealing body 112 will cover the outside of the car mounting hole, and to a certain extent, the body 111 of the buckle will pull it towards the sheet metal, thereby generating appropriate elastic deformation. The sealing body 112 will then stick tightly to the sheet metal outside the car mounting hole, sealing the car mounting hole.

[0019] A second lacing band 14 extends from the outer periphery of the limiting plate 13, and the second lacing band 14 is perpendicular to the first lacing band 12. A limiting portion 141 is provided on the second lacing band 14 at the end away from the limiting plate 13. Preferably, the cross-section of the end where the second lacing band 14 connects to the limiting plate 13 gradually decreases towards the end where the limiting portion 141 is located. Furthermore, it is preferable that the end where the limiting portion 141 connects to the second lacing band 14 has an enlarged portion. More preferably, the end of the limiting portion 141 away from the second lacing band 14 has a sloped or tapered surface. For example, the limiting portion 141 can be a tapered, arrow-shaped, or other structure that gradually increases in size from the front to the rear, thereby facilitating the faster and smoother passage of the limiting portion 141 of the second lacing band 14 through the slot of the automotive trim panel.

[0020] Furthermore, in this embodiment, the multi-directional fastener is preferably an integral structure. It is preferable that the multi-directional fastener is integrally injection molded. It should be noted that the fastener body 111, the first fastener 12, the limiting disc 13, and the second fastener 14, along with the sealing body 112, are preferably obtained through two-color injection molding or two-stage injection molding. (Note: For ease of description, in the following description, the fastener body 111, the first fastener 12, the limiting disc 13, and the second fastener 14 will be collectively referred to as the fastener body.) For example, the fastener body can be obtained through a single injection molding process, followed by a second injection molding process using a flexible material to obtain the sealing body 112. Preferably, the fastener body is made of plastic, such as nylon or POM; the sealing body 112 is preferably made of flexible materials such as TPE or TPU. Of course, the above molding method is the optimal solution selected from a comprehensive consideration of production quality, production cost, and production efficiency, but it is not limited to two-color injection molding or two-stage injection molding. Other molding methods that can achieve the buckle body structure of this application can also be used in the prior art; for example, the buckle body and the sealing body 112 can be processed separately and then assembled by bonding or hot pressing, or other flexible material covering processes can be used to achieve the sealing function. Regardless of the molding method used, it is necessary to ensure that the connection between the sealing body 112 and the buckle body is reliable and the seal is tight, which can effectively prevent moisture and dust from entering the inside of the docking terminal along the cable, thereby improving the overall protection performance and reliability of use. Example

[0021] Item Figure 6-7 As shown, this embodiment discloses an automotive trim panel assembly structure, including a multi-directional strap buckle 10. A first slot 21 is formed on a first surface of the automotive trim panel 20, into which a first strap 12 and a limiting disc 13 are embedded. On a second surface perpendicular to the first surface, a second slot 22 is formed on the automotive trim panel 20, through which a second strap 14 passes, and a limiting portion 141 extends outward from the second slot 22.

[0022] Preferably, the second slot 22 includes a first slot 221 and a second slot 222 that are connected to each other. The width of the first slot 221 is greater than the maximum width of the limiting part 141 and greater than the width of the second slot 222. The width of the second slot 222 is less than the maximum width of the limiting part 141. The second slot 221 is located at the end of the second slot 222 away from the limiting plate 13. An opening 211 is provided at the end of the first slot 21 away from the second slot 22. In order to facilitate the insertion of the first strap 12 and the limiting plate 13 into the first slot 21, this embodiment preferably has a wide-mouth structure, such as a V-shaped opening. In this way, the opening can guide and center the first strap 12 and the limiting plate 13 during the insertion of the first slot 21, thereby facilitating the quick and accurate insertion of the first strap 12 and the limiting plate 13 into the first slot 21.

[0023] During installation, such as Figure 6 As shown, the orientation of the second strap 14 of the multi-directional strap buckle is adjusted, and the buckle 11 is inserted into the mounting hole of the automotive sheet metal 30. Then, the upper part of the second strap 14 of the automotive trim panel 20 is slid down from top to bottom, so that the first strap 12 and the limiting plate 13 are embedded in the first slot 21. At the same time, the limiting part 141 and part of the second strap 14 pass through the first groove 221 of the second slot 22. Finally, the automotive trim panel 20 is slid away from the automotive sheet metal 30. At this time, the second strap 14 moves from the first groove 221 into the second groove 222. Since the size of the limiting part 141 is larger than the second groove 222, the second strap 14 will be limited in the direction perpendicular to the first strap 12. At the same time, the limiting plate 13 limits the first strap 12, thereby constraining the automotive trim panel 20 from two directions. By setting a second strap structure on the limiting plate, the limiting part of the head forms a constraint with the sliding groove of the automotive trim. The second strap and the limiting part exert a large pulling force on the automotive trim, ensuring that the trim cover will not fly out and injure people. It can also be installed in a narrow range and can provide a product with a large pulling force in both the sliding direction and the axis of the mounting hole. It also takes into account the ejection direction of the injection mold of the snap-on product and the production convenience of opening mounting holes on the customer's housing.

[0024] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
