Technical Field
[0001] This utility model relates to the field of automotive clip technology, specifically a waterproof clip for automobiles. Background Technology
[0002] Automotive clips are used during the shipping and final installation of wire harnesses to protect or connect wire harnesses and connectors. With the increasing prevalence of automotive intelligence and the growing use of automotive electronic components, clips, as a common structure for connecting wire harnesses and electrical components, are becoming increasingly widespread in automobiles, leading to more stringent requirements. The extensive use of electrical components necessitates the frequent use of clips as connectors. However, due to the increased complexity of wire harnesses, OEMs are placing higher demands on clips. This raises the issue of adding more barrier functions to clips beyond their original connecting capabilities to meet current standards.
[0003] For example, there is an incompatibility between the current usage requirements of clips (easy insertion) and the requirements for load-bearing, connection, and dry / wet zone separation and sealing functions. Most clips are made of pure plastic, but this utility model's clip for dry / wet zone separation and foreign object blocking perfectly solves this problem. At the same time, due to its wide range of applications, market demands for clips are gradually increasing, requiring not only meeting customers' assembly needs but also providing special functions. However, ordinary clips, due to their structural and material limitations, can no longer meet the assembly requirements in some situations, such as the environmental requirements of dry / wet zone separation in the front and rear compartments of vehicles, preventing moisture intrusion and supporting wiring harnesses. Changing the existing structure cannot completely solve this problem. Utility Model Content
[0004] To address the above problems, this utility model provides a waterproof buckle for automobiles, thus solving the aforementioned issues.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof buckle for automobiles, comprising a buckle body, wherein a bowl-shaped structure is provided at the upper end of the buckle body, a fixing ring is fixed at the upper end of the bowl-shaped structure, and a hydrophobic washer is snapped onto the upper end of the fixing ring; The hydrophobic gasket has two sealing flanges on its outer side, and grooves are provided at both the upper and lower ends of the hydrophobic gasket. The inner side of the fixing ring is provided with a sealing groove that corresponds to the sealing flange. Arc-shaped grooves are provided at the corners of the sealing groove, and multiple protrusions are provided at the lower end of the sealing groove.
[0006] Preferably, a column is fixed to the upper end of the bowl-shaped structure, and two symmetrical snap-fit pieces are fixed to the upper end of the column. The two snap-fit pieces are in a herringbone shape, and a snap-fit platform is provided at the lower end of each snap-fit piece. A lateral through hole is provided on the buckle body.
[0007] Preferably, the outer ring of the hydrophobic gasket has two fixing grooves, which are located between two sealing flanges and correspond to the fixing blocks.
[0008] Preferably, the groove is located between the two protrusions.
[0009] Preferably, the fixing block is a right-angled trapezoid to facilitate quick snapping of the hydrophobic gasket, and sealing rings are snapped and fixed in the arc-shaped grooves respectively.
[0010] Preferably, the buckle body is integrally formed with the bowl-shaped structure, the column, the snap-fit piece, and the snap-fit platform.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through the cooperation of multiple sealing structures such as the sealing flange of the hydrophobic gasket, the sealing groove of the fixing ring, and the sealing ring inside the arc groove, it can effectively prevent water from flowing into the vehicle through the through holes of the body sheet metal, ensuring that the vehicle interior is dry. The design of the various components, such as the snap-fit between the fixing ring and the hydrophobic gasket, and the snap-fit between the snap-fit piece and the body sheet metal, makes it difficult for the buckle to loosen or fall off after installation, and can withstand the vibration and impact during vehicle operation.
[0012] 2. The buckle body is integrally molded with the bowl-shaped structure and column, without splicing gaps, which enhances the overall structural strength and extends the service life. The side through holes of the buckle body can be used to run cables, meeting the needs of cable layout inside the car and improving the practicality of the buckle. The right-angled trapezoidal fixing block and other structural designs provide guidance for component snapping, making it convenient and quick to install and improving installation efficiency.

[0015] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0016] Please see Figure 1 , Figure 2 and Figure 3 A waterproof car clip includes a clip body 1. The clip body 1 serves as the basic load-bearing component of the entire waterproof clip, playing a core supporting and connecting role. Its reasonable structural design provides a stable platform for the installation and assembly of subsequent components. A bowl-shaped structure 11 is provided at the upper end of the clip body 1. This bowl-shaped structure 11 provides good support and positioning for the components above, solving the problem of inaccurate positioning during component installation and making subsequent snap-fit operations more precise. A fixing ring 3 is fixed to the upper end of the bowl-shaped structure 11. The fixing ring 3 is used to snap-fit with a hydrophobic gasket 2, providing an installation base for the hydrophobic gasket 2 and ensuring the stability of the connection with the hydrophobic gasket 2. The hydrophobic gasket 2 is snapped onto the upper end of the fixing ring 3. The hydrophobic gasket 2 is one of the key components for achieving the waterproof function and can effectively prevent water penetration.
[0017] Please see Figure 3 , Figure 4 and Figure 5 The hydrophobic washer 2 has two sealing flanges 21 on its outer side. These sealing flanges 21 enhance the sealing performance between the washer and the fixing ring 3, preventing water from entering through the connection gap. This solves the problem of water leakage caused by poor sealing in traditional snap-fit systems, greatly improving the waterproof effect. The hydrophobic washer 2 has grooves 22 at both its upper and lower ends. The design of these grooves 22 reduces the weight of the hydrophobic washer 2 and also enhances its structural flexibility to a certain extent, facilitating installation and adaptation to different installation environments.
[0018] Please see Figure 3 , Figure 4 and Figure 5The inner side of the fixing ring 3 is provided with a sealing groove 31 corresponding to the sealing flange 21. The cooperation between the sealing groove 31 and the sealing flange 21 allows for a tighter fit, further improving sealing reliability and preventing water from seeping in through the joint. Arc-shaped grooves 32 are respectively provided at the corners of the sealing groove 31, and sealing rings are respectively fixed within these arc-shaped grooves 32. The arc-shaped grooves 32 provide installation space for the sealing rings, and the presence of the sealing rings provides a secondary sealing effect for the cooperation between the sealing groove 31 and the sealing flange 21, solving the sealing leakage problem that may exist if the connection is only structurally fastened, thus improving waterproof performance. Multiple protrusions 33 are provided at the lower end of the sealing groove 31. The protrusions 33 increase the friction with the hydrophobic gasket 2, making the connection more secure and preventing the hydrophobic gasket 2 from loosening or shifting during use, ensuring the stability of the overall snap-fit structure.
[0019] Please see Figure 3 , Figure 4 and Figure 5 The upper end of the bowl-shaped structure 11 is fixed with a column 12, which supports the snap-fit piece 13 above, providing a stable support structure for the snap-fit piece 13 and ensuring that the snap-fit piece 13 can perform its snap-fit function normally. Two symmetrical snap-fit pieces 13 are fixed to the upper end of the column 12. The two snap-fit pieces 13 are in a herringbone shape. This herringbone design increases the contact area and snap-fit force during snap-fit, making the snap-fit more secure and solving the problem of loose snap-fit that is easy to fall off. This improves the reliability of the connection between the snap-fit and body sheet metal and other components. Each snap-fit piece 13 has a snap-fit platform 14 at its lower end. The snap-fit platform 14 can engage with structures on body sheet metal and other components to achieve a stable installation of the snap-fit on the vehicle body and ensure the stability of the snap-fit after installation. The snap-fit body 1 has a lateral through hole, which can be used to pass cables through, meeting the needs of internal vehicle cable routing, increasing the functionality of the snap-fit, and solving the problem of lacking a suitable cable routing structure.
[0020] Please see Figure 3 , Figure 4 and Figure 5The outer ring of the hydrophobic gasket 2 has two fixing grooves 23, which are located between the two sealing flanges 21. The fixing grooves 23 correspond to the fixing blocks 34. The cooperation between the fixing grooves 23 and the fixing blocks 34 can further limit and fix the hydrophobic gasket 2, preventing it from rotating in the circumferential direction and ensuring the positional stability of the hydrophobic gasket 2 after installation. The groove 22 is located between the two protrusions 33. This positional design makes the axial cooperation between the hydrophobic gasket 2 and the fixing ring 3 more reasonable, and there will be no interference between the structures, ensuring the compactness of the overall structure and the smoothness of the cooperation. The fixing block 34 is a right trapezoid, which facilitates the quick snapping of the hydrophobic gasket 2. When snapping, the inclined surface of the right trapezoidal fixing block 34 can play a guiding role, which makes it easy for the hydrophobic gasket 2 to be snapped into the fixing ring 3 quickly and smoothly, improving the installation efficiency and solving the problems of difficult and time-consuming installation.
[0021] Please see Figure 3 , Figure 4 and Figure 5 The buckle body 1 is integrally formed with the bowl-shaped structure 11, the column 12, the snap-fit piece 13 and the snap-fit platform 14. The integral forming design makes the connection between these components more secure, with no connection gaps, avoiding structural weak points that may be caused by component splicing, improving the structural strength and stability of the entire buckle body 1, while also simplifying the production process and reducing production difficulty and cost.
[0022] The combined structure achieves excellent waterproofing. Through the multiple sealing mechanisms of the sealing flange 21 of the hydrophobic washer 2 and the sealing groove 31 and arc-shaped groove 32 of the fixing ring 3, water is effectively prevented from entering the vehicle through the body panel holes, ensuring a dry interior and solving problems such as dampness and component damage caused by water seepage from the body panel holes. Secondly, the interlocking and fixing of the components, such as the interlocking between the fixing ring 3 and the hydrophobic washer 2, and the interlocking between the interlocking piece 13 and the body panel, ensures a secure and stable waterproof buckle installation, preventing it from easily falling off. This improves the reliability and durability of the buckle on the vehicle, solving the problem of buckles loosening and falling off, thus affecting its use. Furthermore, the integrated buckle body 1 and the rational structural design of each component ensure the overall structural strength of the buckle, enabling it to withstand vibrations and impacts during vehicle operation and extending its service life. In addition, the side through-hole design meets the needs of cable routing inside the car, increases the practicality and functionality of the clips, and provides convenience for wiring inside the car.
[0023] When using this utility model: First, the hydrophobic gasket 2 and the fixing ring 3 are snapped together. Using the right-angled trapezoidal guide of the fixing block 34, the sealing flange 21 of the hydrophobic gasket 2 is aligned with the sealing groove 31 of the fixing ring 3 and snapped in. At the same time, the fixing groove 23 cooperates with the fixing block 34, and the sealing ring in the arc groove 32 also plays a secondary sealing role, ensuring that the two are tightly connected and waterproof. Next, the assembled fixing ring 3 and hydrophobic gasket 2 are snapped together and installed on the corresponding position of the body sheet metal through the herringbone-shaped snap-fit piece 13 and snap-fit platform 14 on the snap-fit body 1. During the installation process, the bowl-shaped structure 11 and the column 12 provide stable support to ensure a firm snap-fit. If there are in-vehicle cables that need to be laid, the cables can be passed through the side through holes on the snap-fit body 1 to achieve orderly wiring. In this way, the cooperation of the various structures not only achieves reliable waterproof sealing, but also ensures the stability of the snap-fit installation and the convenience of cable laying.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
