Description

Technical Field

[0001] This application belongs to the field of vehicle technology, specifically relating to a snap-fit ​​assembly, a body system, and a vehicle. Background Technology

[0002] With the rapid development of vehicle intelligent connectivity technology, vehicle electronic systems are becoming increasingly complex, and different vehicle models have significantly different requirements for wiring harness specifications, resulting in a trend of diversification in wiring harnesses.

[0003] However, existing snap-fit ​​components, due to their fixed dimensions, can only accommodate wiring harnesses of a single diameter. This necessitates the development of custom-designed snap-fit ​​components for each vehicle model, resulting in poor versatility. This not only significantly increases the variety of snap-fit ​​components but also keeps automakers' costs high in areas such as R&D, production, and inventory management.

[0004] Therefore, there is an urgent need to design a snap-fit ​​component to improve product versatility, reduce development costs, and meet the diverse technical needs of vehicles. Utility Model Content

[0005] The purpose of this application is to provide a snap-fit ​​assembly, a body system, and a vehicle that can solve at least some of the aforementioned problems.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] In a first aspect, embodiments of this application provide a snap-fit ​​assembly, including a first base and a second base, the first base and the second base enclosing a receiving space for accommodating a wire harness; one end of the second base is flexibly connected to the first base, and the other end of the second base is movably connected to the first base to adjust the size of the receiving space.

[0008] In this embodiment, the first base and the second base cooperate to form a receiving space for accommodating the wire harness. The shape of the receiving space is adapted to the outer contour of the wire harness and can be circular, elliptical, or polygonal. One end of the second base and the first base are flexibly connected via a flexible connector. This flexible connector can be integrally molded from a highly elastic TPE (thermoplastic elastomer) material, with a wavy cross-section, ensuring flexibility while possessing a certain tear resistance. One end of the flexible connector is firmly bonded to the outer wall of the first base using an injection molding process, and the other end is fixed to the outer wall of the second base using the same injection molding method. This connection method allows the second base to swing or elastically deform relative to the first base at a certain angle, using the flexible connector as a fulcrum. Furthermore, when adjusting the size of the receiving space, the flexible connector maintains the stability of the connection, preventing the first base from detaching from the second base.

[0009] The other end of the second base and the first base can be movably connected through an adjustable sliding connection structure. Through the flexible connection between the second and first bases and the adjustable sliding connection structure, the accommodating space of the clip assembly can be flexibly adjusted within a diameter range of 35-45mm. Whether it's the delicate sensor harness of a small car, the robust high-voltage power battery harness of a large SUV, or the complex multi-wire harness integration of a new energy commercial vehicle, this clip assembly can achieve stable fixation through simple manual adjustment, greatly expanding the range of applicable wire harness specifications. Furthermore, by simply adjusting the accommodating space of this clip assembly, it can adapt to the wire harnesses of new car models, effectively reducing the degree of customization of parts during the development of new models and shortening the R&D cycle. Using the clip assembly of this application, only a small number of these clips need to be stocked to meet the wire harness fixing needs of most car models, significantly reducing inventory management costs and warehouse space occupation. It also reduces the waste of parts due to model updates and improves the efficiency and economic benefits of the company's supply chain management.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] The following description, in conjunction with the accompanying drawings, details the buckle assembly, body system, and vehicle provided in this application through specific embodiments and application scenarios.

[0028] See Figures 1 to 4 The embodiments of this application provide a snap-fit ​​assembly for fixing wire harnesses, including a first base 1 and a second base 2, the first base 1 and the second base 2 forming an accommodating space for accommodating wire harnesses; one end of the second base 2 is flexibly connected to the first base 1, and the other end of the second base 2 is movably connected to the first base 1 to adjust the size of the accommodating space.

[0029] In this embodiment, specifically designed for vehicle wiring harness fixing, its core consists of a first base 1 and a second base 2. The first base 1 and the second base 2 cooperate to form a receiving space for accommodating the wiring harness. The shape of this receiving space is adapted to the outer contour of the wiring harness and can be circular, elliptical, or polygonal. One end of the second base 2 and the first base 1 are flexibly connected via a flexible connector. This flexible connector can be integrally molded from a highly elastic TPE (thermoplastic elastomer) material, with a wavy cross-section, ensuring flexibility while possessing a certain tear resistance. One end of the flexible connector is firmly bonded to the outer wall of the first base 1 using an injection molding process, and the other end is also fixed to the outer wall of the second base 2 using the same injection molding method. This connection method allows the second base 2 to swing or elastically deform relative to the first base 1 at a certain angle, using the flexible connector as a fulcrum. Furthermore, when adjusting the size of the receiving space, the flexible connector maintains the stability of the connection, preventing the first base 1 from detaching from the second base 2.

[0030] The other end of the second base 2 and the first base 1 can be movably connected via an adjustable sliding connection structure. For example, the second base 2 has a dovetail-shaped adjusting slider at this end, with inclined guide surfaces on both sides of the slider; the first base 1 has a corresponding dovetail-shaped adjusting groove, with guide protrusions on the inner wall of the groove that mate with the slider's guide surface, ensuring that the adjusting slider can only slide along the length of the groove. The adjusting slider has equally spaced inverted tooth-shaped limiting protrusions, and the adjusting groove has limiting grooves that mate with the limiting protrusions. When the second base 2 is pushed to make the adjusting slider slide within the adjusting groove, the limiting protrusions can engage with the limiting grooves at different positions, achieving multi-level adjustment of the accommodating space. For example, the second base 2 can also be connected to the first base 1 via a cable tie-like structure. The tooth-like structure can have multiple teeth, and the first base 1 can have a component that fixes the teeth, or multiple structures that engage with the teeth. When the tooth-like structure slides in the component with fixed teeth, or is connected to different structures that engage with the teeth, multi-level adjustment of the size can be achieved.

[0031] Furthermore, when it is necessary to fix a thicker wire harness, the second base 2 can be pushed to slide the adjusting slider away from the flexible connection part, or only a small part of the toothed structure can be pushed into the fixed tooth component to increase the accommodating space. Conversely, sliding it closer to the flexible connection part or pushing most of the toothed structure into the fixed tooth component can reduce the accommodating space. After adjustment, the limiting protrusion and the limiting groove engage and lock, connecting the toothed structure and the fixed tooth component to prevent the second base 2 from moving on its own.

[0032] In this embodiment, through the flexible connection and adjustable sliding connection structure between the second base 2 and the first base 1, the accommodating space of the snap-fit ​​assembly can be flexibly adjusted within a diameter range of 35-45mm. Whether it's the slender sensor harness of a small car, the robust high-voltage power battery harness of a large SUV, or the complex multi-wire harness integration of a new energy commercial vehicle, this snap-fit ​​assembly can achieve stable fixation through simple manual adjustment, greatly expanding the range of applicable wire harness specifications. Furthermore, by simply adjusting the accommodating space of this snap-fit ​​assembly, it can adapt to the wire harnesses of new car models, effectively reducing the degree of customization of parts during the development of new models and shortening the R&D cycle. Using the snap-fit ​​assembly of this application, only a small number of these snap-fits need to be stocked to meet the wire harness fixing needs of most car models, significantly reducing inventory management costs and warehouse space occupation. It also reduces the waste of parts due to model updates and improves the efficiency and economic benefits of the enterprise's supply chain management.

[0033] It should be noted that, as Figure 1As shown, the two protrusions 11 on the left and right are approximately 5mm wide and 3mm high, located at the bottom left and right sides of the first base 1. A square hole of approximately 2mm x 1.5mm is hollowed out in the middle for weight reduction. The main purpose of these two protrusions 11 is to ensure that after the sheet metal connection of the snap-fit ​​assembly is assembled onto the sheet metal, when the snap-fit ​​tilts, these two protrusions will generate a certain clamping force to ensure that the snap-fit ​​assembly quickly returns to balance, thereby ensuring the fastening and sealing effect of the snap-fit ​​assembly.

[0034] The two slots 12 on the left and right are approximately 3mm wide and 10mm deep, with thin walls on both sides and an opening size of approximately 2mm, resembling a bottle mouth that is smaller at the top and larger at the bottom. These two slots 12 are used in conjunction with the two claws on the interior door sill trim to ensure that the door sill trim is securely fastened to the door sill clips after installation, preventing it from loosening and facilitating easy installation and removal.

[0035] Optionally, in this embodiment of the application, the first base 1 includes a first connecting portion, the second base 2 includes a second connecting portion, and the first connecting portion and the second connecting portion are movably connected.

[0036] In this embodiment, either the first connecting part or the second connecting part can be a U-shaped groove structure, with slide rails symmetrically arranged on both side walls along its length. The other is a slider structure adapted to the U-shaped groove, with slide grooves on both sides of the slider that slide in cooperation with the slide rails, allowing the second connecting part to slide along the length of the first connecting part. At the bottom of the U-shaped groove of the first connecting part, multiple positioning holes are spaced apart, and the second connecting part has a through hole 311 at the corresponding position, equipped with a removable positioning pin. When the second base 2 is pushed to slide the second connecting part within the first connecting part, it can be adjusted to a suitable position according to the diameter of the wire harness. Then, the positioning pin is inserted into the corresponding positioning hole and through hole 311 to lock the position of the second connecting part, thereby precisely adjusting the size of the accommodating space. In this embodiment, by adjusting the size of the accommodating space through the adjustable connection between the first and second connecting parts, the buckle assembly can be matched with wire harnesses of various sizes, thus improving the versatility of the buckle assembly.

[0037] Furthermore, to further enhance versatility and fixation, removable rubber pads can be provided on the inner sidewalls of the first base 1 and the second base 2. The surface of the rubber pads has crisscrossing anti-slip patterns, and the pads are connected to the inner sidewalls of the bases through embedded slots 12. Rubber pads with different hardness and patterns can be replaced according to different wire harness surface materials, enhancing the adaptability and fixation force for various wire harnesses.

[0038] Optionally, in this embodiment, one of the first connecting part and the second connecting part is a socket 14, and the other is a locking tooth 21. The locking tooth 21 is movably inserted into the socket 14. At least a first limiting member 15 and a second limiting member 16 are provided in the socket 14. Along the depth direction of the socket 14, the first limiting member 15 and the second limiting member 16 are sequentially connected to the inner wall of the socket 14. The first limiting member 15 and the second limiting member 16 can limit the locking tooth 21.

[0039] In this embodiment, the insertion port 14 can be a long, narrow groove structure, with the groove width slightly smaller than the internal width of the groove body, forming a trapezoidal cross-section that is wider inside and narrower outside to prevent the locking teeth 21 from dislodging. The groove body can be integrally molded from high-strength engineering plastic, with a frosted inner surface to enhance friction with the locking teeth 21. The locking teeth 21 can be multiple wedge-shaped protrusions, with their bevel angles adapted to the inner wall of the insertion port 14, enabling smooth insertion into the insertion port 14 while providing a stable engagement effect. The surface of the locking teeth 21 is provided with anti-slip textures to further improve the connection stability with the insertion port 14.

[0040] Along the depth direction of the socket 14, a first limiting member 15 and a second limiting member 16 are sequentially provided on its inner wall. The first limiting member 15 and the second limiting member 16 can be elastic limiting blocks with good elastic recovery ability and wear resistance. The top of each limiting block is hemispherical and has an inclined guide surface to facilitate the sliding and locking of the locking tooth 21. The first limiting member 15 is close to the opening end of the socket 14, and the second limiting member 16 is located inside the first limiting member 15. The distance between the two is designed according to the difference in diameter of common wire harnesses to ensure that at least two levels of spatial adjustment can be achieved. When the locking tooth 21 is inserted into the socket 14, it passes over the first limiting member 15 and the second limiting member 16 in sequence. Each time it passes over a limiting member, it will be locked in the corresponding position due to the elastic reset of the limiting block, thereby realizing the adjustment of the size of the accommodating space.

[0041] In this embodiment, through the insertion and removal and limiting of the locking teeth 21 within the socket 14, and the graded positioning of the first limiting member 15 and the second limiting member 16, the accommodating space of the buckle assembly can be adjusted in at least two levels, effectively solving the problem that traditional buckles can only adapt to a single specification of wire harness. The trapezoidal cross-section design of the socket 14 and the wedge-shaped structure of the locking teeth 21 cooperate to form a barbed anti-detachment structure. Combined with the elastic locking of the limiting members, even when the vehicle is driving on bumpy roads, it can prevent the second base 2 from loosening and shifting, ensuring the reliability of the wire harness fixation.

[0042] Optionally, in this embodiment, the inner wall of the first base 1 is provided with at least one first protrusion 13, the first protrusion 13 extends along the width direction of the first base 1, and the first protrusion 13 protrudes from the inner wall of the first base 1 in a direction close to the receiving space; and / or, the inner wall of the second base 2 is provided with at least one second protrusion 22, the second protrusion 22 extends along the width direction of the second base 2, and the second protrusion 22 protrudes from the inner wall of the second base 2 in a direction close to the receiving space.

[0043] In this embodiment, the inner wall of the first base 1 is provided with a first protrusion 13, or the inner wall of the second base 2 is provided with a second protrusion 22, or the inner wall of the first base 1 is provided with a first protrusion 13 and the inner wall of the second base 2 is provided with a second protrusion 22, which can be determined according to the actual situation, and this embodiment does not limit it in any way. Furthermore, the first protrusion 13 and the second protrusion 22 can be made of rigid material, or they can be made of elastic silicone material, with a semi-elliptical cross-section, a smooth surface, and a certain degree of softness. The first protrusion 13 and the second protrusion 22 are distributed at intervals along the length direction of the base. In practical applications, when the first base 1 and the second base 2 are connected, when the wire harness is thin, the wire harness can contact the first protrusion 13 and the second protrusion 22; when the wire harness is thick, the wire harness can be squeezed on both sides of the first protrusion 13 and the second protrusion 22 so that the protrusions fit against the surface of the wire harness, thereby providing an adjustable fixing space for wire harnesses of different thicknesses.

[0044] Optionally, in this embodiment of the application, the buckle assembly further includes a connector 3, which is connected to the first base 1 and extends away from the first base 1. The connector 3 includes a rod 31 and at least two steps 32, which are fixedly connected to the outer periphery of the rod 31. The at least two steps 32 are arranged sequentially along the extension direction of the rod 31, and the width of the steps 32 perpendicular to the rod 31 gradually increases along the direction away from the first base 1.

[0045] In this embodiment, the connector 3 is used to connect the snap-fit ​​assembly to the body sheet metal. The end of the connector 3 extending away from the first base 1 can be connected to or inserted into the body sheet metal to fix the snap-fit ​​assembly to the body sheet metal. Steps 32 are fixedly connected to the outer periphery of the rod 31, arranged sequentially along the extension direction of the rod 31. Along the direction away from the first base 1, the width of the steps 32 perpendicular to the rod 31 gradually increases, forming a stepped, outwardly expanding structure. In practical applications, the number of steps 32 can be designed to be 2-4 according to actual needs. The height difference of each step 32 is precisely calculated, allowing the step 32 combination to adapt to body sheet metal of different thicknesses from 1.0 to 2.5 mm. The surface of the steps 32 is provided with fine, serrated anti-slip textures to increase friction with the sheet metal surface and ensure a stable fixation.

[0046] In this embodiment, the multi-step structure design of the connector 3, through the flexible combination of 2-4 steps 32, can accurately adapt to various body sheet metals within the thickness range of 1.0-2.5mm. Whether it is the thinner 1.0mm door sill sheet metal of a small new energy passenger vehicle or the thicker 2.5mm sheet metal of a large SUV, simply selecting the corresponding step 32 to fit against the sheet metal achieves a stable installation, basically covering the sheet metal thickness requirements of all passenger vehicle door sill positions, effectively solving the problem that traditional clips are difficult to adapt to different sheet metal thicknesses. The clip assembly of this application, with its multi-step connector 3, achieves one product adaptability to multiple sheet metal thicknesses. During the production process of different models, automakers do not need to change the clip type due to differences in sheet metal thickness, significantly reducing the types of parts, reducing the complexity of production management, and significantly improving the versatility of the clip assembly in the field of new energy vehicles. Since there is no need to design and manufacture clip molds separately for each sheet metal thickness, this solution greatly saves mold development costs. At the same time, the large-scale production of a single model of clip can reduce raw material procurement costs and production and manufacturing costs. In addition, reducing the variety of parts also lowers warehousing management costs, avoids waste of parts due to model updates, and effectively controls the company's overall production costs.

[0047] Furthermore, during actual installation, operators can quickly select the appropriate step 32 for installation based on the actual thickness of the vehicle body sheet metal, eliminating the need for complex adjustment steps and improving assembly efficiency. The serrated anti-slip texture on the surface of step 32 tightly engages with the sheet metal, and combined with the high-strength support of the rod 31, it ensures that the clip assembly and the sheet metal do not loosen or shift even when the vehicle is traveling on bumpy roads, ensuring the long-term stability and reliability of the wiring harness fixation.

[0048] Optionally, in this embodiment of the application, the connector 3 further includes a pressing part 33, which is connected to one end of the rod 31 near the first base 1. The pressing part 33 is disposed on the outer periphery of the rod 31 and is inclined in the direction away from the first base 1 along the direction away from the first base 1.

[0049] In this embodiment, the clamping part 33 is connected to the end of the rod 31 near the first base 1 and is arranged around the outer periphery of the rod 31. Along the direction away from the first base 1, the clamping part 33 is inclined in a direction away from the first base 1, with an inclination angle of 15°-30°. It can be understood that the clamping part 33 is an umbrella-shaped inclined structure. Compared to a common planar structure, the clamping part 33 of this application can effectively reduce shaking when clamping the clamped part. When the clamped part is a sealing element 4, it has the beneficial effect of improving the sealing effect.

[0050] Optionally, in this embodiment of the application, the rod 31 is provided with a through hole 311 along the extension direction of the rod 31.

[0051] In this embodiment, the through hole 311 formed along the extension direction of the rod 31 significantly reduces material usage without affecting its load-bearing strength. Compared to a solid rod 31, the rod 31 with the through hole 311 is lighter, contributing to a reduction in the overall weight of the vehicle. In the field of new energy vehicles, vehicle lightweighting is of great significance for improving driving range and reducing energy consumption. This design aligns with the lightweighting trend in the automotive industry and meets the needs of automakers for weight reduction in components.

[0052] Optionally, in this embodiment, the buckle assembly further includes a seal 4, which is disposed on the outer periphery of the rod 31 and on the side of the pressing part 33 away from the first base 1.

[0053] In this embodiment, the seal 4 is disposed on the outer periphery of the rod 31 and located on the side of the pressing part 33 away from the first base 1. The seal 4 has a ring structure and can be made of ethylene propylene diene monomer (EPDM) foam material, which has good elasticity, weather resistance, and waterproof performance. The inner ring of the seal 4 is tightly fitted onto the rod 31, and the outer ring diameter is larger than the diameter of the widest part of the pressing part 33, forming an outwardly protruding sealing lip. When the snap-fit ​​assembly is installed on the vehicle body sheet metal, the seal 4 undergoes elastic deformation under the pressure of the sheet metal, and the sealing lip fits tightly against the sheet metal surface, forming multiple sealing barriers to effectively prevent moisture, dust, and other impurities from entering the vehicle door sill. At the same time, the seal 4 cooperates with the pressing part 33 to further enhance the sealing performance between the snap-fit ​​assembly and the sheet metal.

[0054] Optionally, in this application embodiment, a vehicle body system is provided, including: a vehicle body sheet metal; a clip assembly as described above; the clip assembly is connected to the vehicle body sheet metal and is used to fix the wiring harness to the vehicle body sheet metal.

[0055] In this embodiment, the snap-fit ​​assembly is connected to a multi-step fixing structure on the vehicle body sheet metal that can accommodate different sheet metal thicknesses. Assembly tests have proven that it can fix sheet metal of different thicknesses from 1.0 to 2.5 mm, which can basically cover all the needs of different sheet metal thicknesses at this door sill position for all passenger vehicles. The original method of using one type of door sill snap for one model can be unified into using one type of door sill snap for multiple models, which has strong versatility, greatly reduces the number of door sill snap varieties, and reduces development costs.

[0056] Alternatively, embodiments of this application provide a vehicle including the aforementioned body system.

[0057] In this embodiment, the vehicle includes the body system as described above, and also includes all the structural features and beneficial effects of the body system, which will not be repeated here.

[0058] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Furthermore, it should be noted that the scope of the methods and apparatuses in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved.
