Description

Technical Field

[0001] This utility model relates to a high-voltage wire harness fixing clamp and a new energy vehicle, belonging to the field of wire harness clamp technology. Background Technology

[0002] In the field of new energy vehicles, high-voltage wiring harnesses are the core of power transmission. Their fixed reliability directly determines the safety of the electrical system, affecting vehicle range, driving safety, and the avoidance of faults such as short circuits and leakage. It is a key component design. Currently, the industry generally uses traditional pipe clamps and bolts to fix high-voltage wiring harnesses. Specifically, through holes are made in the pipe clamps, and bolts are used to lock the pipe clamps to the vehicle bracket or equipment frame to achieve wiring harness positioning.

[0003] However, as the requirements of new energy vehicles for production efficiency, operational reliability and cost control increase, traditional solutions have exposed several defects, which restrict industry demand: (1) Low efficiency, bolts require tools to operate, which increases assembly complexity and extends working time. Bolt disassembly and assembly are difficult in narrow spaces, hindering later maintenance. (2) Poor reliability, vehicle vibration and environmental corrosion can easily cause bolts to loosen, reduce the clamping force of pipe clamps, cause wire harness shaking and wear, and even induce short circuits and leakage. (3) High adaptation cost, traditional pipe clamps have a fixed clamping distance and can only adapt to wire harnesses of a single diameter; multiple specifications of wire harnesses require multiple pipe clamps, which increases management difficulty and inventory costs. (4) Short lifespan, some pipe clamps do not have a dedicated limiting structure, vehicle vibration causes wire harness displacement and wear, accelerates skin aging, shortens lifespan and amplifies safety risks.

[0004] In summary, the shortcomings of traditional solutions in terms of efficiency, reliability, cost, and lifespan make them unable to meet the needs of new energy vehicles, and there is an urgent need for new high-voltage wiring harness fixing solutions to break through the bottleneck. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides a high-voltage wire harness fixing clamp and a new energy vehicle, which can simplify the installation process, adapt to various specifications of wire harnesses, and provide reliable fixing.

[0006] To achieve the above objectives, this utility model employs a high-voltage wire harness fixing clamp, comprising a base plate, a clamping plate, and a bending portion. The base plate has a connecting end and an open end. A retaining seat is integrally formed on the outer surface of the base plate, and the side surface of the retaining seat is provided with an elastic element for engaging with a vehicle bracket, thereby achieving boltless fixing of the clamp to the bracket. The clamping plate has a connecting end and an open end, and the inner surface of the clamping plate has multiple clamping grooves for limiting the high-voltage wire harness. An adjustable clamping structure for adjusting the clamping distance is provided between the open end of the clamping plate and the open end of the base plate. The bending portion is arc-shaped, and its two ends are respectively connected to the connecting end of the base plate and the connecting end of the clamping plate. The base plate, clamping plate, and bending portion are integrally formed to form a U-shaped structure.

[0007] As an improvement, the adjustable clamping structure includes a connecting groove, at least two retaining rings, and a retaining slot; the connecting groove is located inside the opening end of the base plate; one end of the retaining ring is a movable end and is movably installed in the connecting groove and can rotate, and the other end of the retaining ring is a free end and is adapted to engage with the retaining slot; the retaining slot is located outside the opening end of the clamping plate and corresponds to the position of the retaining ring.

[0008] As an improvement, the retaining ring includes a first retaining ring and a second retaining ring, the first retaining ring and the second retaining ring having different lengths to accommodate high-voltage wire harnesses of different diameters.

[0009] As an improvement, the inner surface of the base plate is provided with a placement groove for placing the free end of the retaining ring, the size of which is adapted to the size of the free end of the retaining ring.

[0010] As an improvement, the elastic element is a locking block with a triangular cross-section, and the lower edge of the locking block is integrally formed with the locking seat.

[0011] As an improvement, each of the card holders has two card blocks symmetrically arranged on its side surface. Each card block has a protrusion at its upper end that protrudes away from the card holder for engaging the vehicle bracket.

[0012] As an improvement, at least two card holders are provided at intervals along the length of the base plate on the outer surface of the base plate.

[0013] As an improvement, the inner wall of the clamping groove is provided with a protective layer for reducing wear on the high-voltage wiring harness, the protective layer being made of an elastic insulating material.

[0014] In a second aspect, this utility model also provides a new energy vehicle, wherein the high-voltage wiring harness fixing part of the new energy vehicle is equipped with the high-voltage wiring harness fixing clamp.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Simplified Installation and Maintenance: The pipe clamp features a U-shaped, one-piece molded base plate, clamping plate, and bending section. Combined with a one-piece molded bracket on the outer side of the base plate and elastic elements on the bracket's side surface, the pipe clamp can be fixed to the vehicle bracket without bolts. During installation, the elastic elements quickly snap into the pre-set holes in the bracket, significantly reducing assembly steps, especially in confined spaces where installation efficiency is greatly improved. For later maintenance, the pipe clamp can be easily removed simply by utilizing the elastic deformation of the elastic elements, effectively reducing maintenance difficulty.

[0017] 2. Improved clamping adaptability: An adjustable clamping structure is provided between the open end of the clamping plate and the open end of the base plate. The clamping range between the base plate and the clamping plate can be flexibly adjusted according to the diameter of the high-voltage wire harness, adapting to various specifications of wire harnesses, reducing the types of spare parts and reducing inventory costs. At the same time, multiple clamping grooves are opened on the inner surface of the clamping plate, which can accurately limit the wire harness, prevent the wire harness from shifting in the vehicle vibration environment, reduce the wear of the wire harness skin, and extend the service life of the wire harness.

[0018] 3. Enhanced Fixing Reliability: The one-piece molded U-shaped structure (base plate, clamping plate, and bending part are integrally molded) has high structural strength. Combined with the locking effect of the adjustable clamping structure, it can provide stable clamping force for the wire harness. The design of the card holder and the elastic element ensures that the pipe clamp is firmly connected to the vehicle bracket. It can effectively resist the influence of external forces such as vibration and impact during vehicle operation, avoid the problem of easy loosening of traditional bolt connections, and reduce the safety hazards such as short circuits and leakage caused by wire harness fixing failure.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this application will be described in detail below through specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figures 1-5 As shown, a high-voltage wire harness fixing clamp includes a base plate 1, a clamping plate 2, and a bending part 3;

[0029] The base plate 1 has a connecting end and an open end. The outer surface of the base plate 1 is integrally formed with a card seat 9. The side surface of the card seat 9 is provided with a spring member for engaging with the vehicle bracket. The engagement between the spring member and the bracket enables boltless fixing of the pipe clamp and the bracket, thereby reducing assembly steps and improving the efficiency of installation in confined spaces and subsequent maintenance.

[0030] The clamping plate 2 has a connecting end and an open end. The inner surface of the clamping plate 2 is provided with a plurality of clamping grooves 4 for limiting the high-voltage wire harness. The clamping grooves 4 limit the wire harness to prevent the wire harness from displacing and wearing when the vehicle vibrates. An adjustable clamping structure for adjusting the clamping distance is provided between the open end of the clamping plate 2 and the open end of the base plate 1. The clamping distance can be adjusted to adapt to high-voltage wire harnesses of different diameter specifications.

[0031] The bending part 3 is arc-shaped, and its two ends are connected to the connecting end of the base plate 1 and the connecting end of the clamping plate 2, respectively. The base plate 1, the clamping plate 2 and the bending part 3 are integrally formed to form a U-shaped structure. The integrally formed U-shaped structure improves the overall structural strength of the pipe clamp, enhances its resistance to vibration and impact, and ensures the long-term reliability of the wire harness.

[0032] In some embodiments, such as Figures 1-4 As shown, the adjustable clamping structure includes a connecting groove 5, at least two retaining rings, and a retaining groove 8;

[0033] The connecting groove 5 is opened on the inner side of the opening end of the base plate 1. Each retaining ring has a movable end and a free end. The movable end of the retaining ring is movably installed in the connecting groove 5 and can rotate flexibly around the contact position between the two. The shape of the free end matches the groove structure of the slot 8. When rotated to the designated position, it can be accurately locked into the slot 8 to form a stable locking structure. Since there are no less than two retaining rings, different retaining rings can be designed with different lengths to provide differentiated options for subsequent adjustment of the clamping distance.

[0034] The slot 8 is located on the outside of the opening end of the clamping plate 2. Its position corresponds to the installation position of the retaining ring in the connecting groove 5. Specifically, the slot 8 fits with the free end of the retaining ring, ensuring that the free end can be accurately aligned and smoothly inserted when any retaining ring rotates. When it is necessary to adjust the clamping distance between the base plate 1 and the clamping plate 2, simply select a retaining ring of the corresponding length according to the actual diameter of the high-voltage wire harness.

[0035] In some embodiments, such as Figures 2-4 As shown, the retaining ring includes a first retaining ring 6 and a second retaining ring 7, wherein the lengths of the first retaining ring 6 and the second retaining ring 7 have a preset difference (for example, the length of the second retaining ring 7 is greater than the length of the first retaining ring 6). When it is necessary to fix a high-voltage wire harness with a smaller diameter, the movable end of the first retaining ring 6 can be rotated in the connecting groove 5, so that the free end of the first retaining ring 6 is inserted into the retaining groove 8 on the outside of the clamping plate 2. At this time, a small clamping space is formed between the base plate 1 and the clamping plate 2 to accommodate the small-diameter wire harness. When it is necessary to fix a high-voltage wire harness with a larger diameter, the second retaining ring 7 can be selected, and its free end can be inserted into the retaining groove 8 in the same rotation and clamping manner, so that the clamping space between the base plate 1 and the clamping plate 2 is increased, thereby achieving stable clamping of high-voltage wire harnesses of different diameter specifications and further improving the adaptability and flexibility of the adjustable clamping structure.

[0036] In some embodiments, such as Figure 1 , Figure 2 As shown, a placement groove 11 for placing the free end of an idle retaining ring is also provided on the inner surface of the base plate 1. The depth, width, and length of the placement groove 11 are all adapted to the size of the free end of the retaining ring. The depth of the placement groove 11 is slightly greater than the thickness of the free end of the retaining ring, the width is the same as the width of the free end of the retaining ring, and the length can accommodate at least one free end of the retaining ring to be fully embedded, ensuring that the free end of the idle retaining ring can be stably placed in the groove and does not protrude from the inner surface of the base plate 1. When only some retaining rings are used in the adjustable clamping structure (such as selecting the first retaining ring 6 to fix the wire harness and the second retaining ring 7 being in an idle state), the free end of the idle retaining ring can be aligned with the placement groove 11 and embedded in it. This can prevent the free end of the idle retaining ring from dangling inside the base plate 1, preventing it from rubbing against the high-voltage wire harness and causing wire harness wear, and can also form a storage limit for the idle retaining ring, preventing the idle retaining ring from shaking randomly when the vehicle vibrates, causing abnormal noise or affecting other components, further improving the stability and convenience of using the pipe clamp.

[0037] In some embodiments, such as Figures 1-5 As shown, the elastic component is a triangular-shaped locking block 10. This triangular cross-section design can enhance the locking stability by utilizing structural characteristics. The side facing the vehicle bracket forms an inclined guide surface, which facilitates the quick insertion of the locking block 10 into the bracket's preset hole. The other side forms a vertical limiting surface, which can effectively prevent loosening after locking and improve the connection reliability between the pipe clamp and the bracket. The lower edge of the locking block 10 and the locking seat 9 are processed by an integral molding process, which not only saves additional assembly processes and avoids the risk of separation between the locking block 10 and the locking seat 9 during later use, but also enhances the connection strength between the two, ensuring that the locking block 10 is not easily deformed or broken when subjected to external forces such as vehicle vibration and impact, further ensuring the long-term stability of the boltless fixing of the pipe clamp.

[0038] To further enhance the bonding strength, such as Figure 5 As shown, each card holder 9 has two card blocks 10 symmetrically arranged on its side surface, and each card block 10 has a protrusion at its upper end that protrudes away from the card holder 9. This protrusion can form a mechanical limit with the hole wall after the card block 10 is inserted into the preset hole of the bracket, so as to prevent the pipe clamp from moving along the hole axis and finally achieve a stable connection between the pipe clamp and the vehicle bracket.

[0039] In some embodiments, such as Figures 1-5 As shown, at least two card holders 9 are spaced apart along the length of the base plate 1 on the outer surface of the base plate 1, and the spacing between adjacent card holders 9 is adapted to the spacing of the mounting holes on the vehicle bracket. By setting multiple spaced card holders 9 along the length of the base plate 1, the pipe clamp can be connected to the vehicle bracket simultaneously through multiple card holders 9. On the one hand, this can disperse the pressure of the pipe clamp and the weight of the wire harness on a single connection point, avoiding excessive local stress that could damage the card holder 9 or the bracket. On the other hand, it can form multi-point positioning, effectively limiting the rotation or displacement of the pipe clamp during vehicle vibration, further enhancing the overall stability of the connection between the pipe clamp and the bracket, and ensuring the reliability of long-term fixation of the high-voltage wire harness.

[0040] In some embodiments, the inner wall of the clamping groove 4 is completely covered with a protective layer to reduce wear of the high-voltage wiring harness. The shape of the protective layer is perfectly matched with the contour of the inner wall of the clamping groove 4, and the thickness of the protective layer is uniform (e.g., the thickness is set to 0.5-1mm). This ensures that the wiring harness can bear the force evenly when it comes into contact with the clamping groove 4, and avoids damage to the protective layer due to excessive local pressure. The protective layer is made of an elastic insulating material (such as silicone, nitrile rubber, etc.). Its elastic properties can buffer the collision and impact between the wiring harness and the inner wall of the clamping groove 4 during vehicle vibration, further reducing the risk of wear. At the same time, the insulating properties can isolate the wiring harness from direct contact with the metal parts of the pipe clamp (if the pipe clamp is made of metal), avoiding safety hazards such as short circuits and leakage caused by insulation failure. This not only ensures the service life of the wiring harness, but also improves the electrical safety of the pipe clamp.

[0041] Finally, this utility model also provides a new energy vehicle in which the above-mentioned high-voltage wiring harness fixing clamps are installed at the high-voltage wiring harness fixing parts (such as the battery pack periphery, chassis wiring harness channel, motor controller connection area, etc.).

[0042] By applying this pipe clamp to the high-voltage wiring harness fixing parts of new energy vehicles, the boltless fixing design of the pipe clamp simplifies the vehicle assembly process and improves production efficiency. Furthermore, the adjustable clamping structure adapts to high-voltage wiring harnesses of different diameters, reducing the variety of spare parts and inventory costs. Simultaneously, the protective layer of the pipe clamp groove, the integrated U-shaped structure, and the stable snap-fit ​​fixing method effectively ensure the reliability of the high-voltage wiring harness under long-term vehicle vibration and complex operating conditions, reducing electrical safety hazards caused by wiring harness wear or loosening, and further improving the operational safety and service life of new energy vehicles.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
