[0002] The high-voltage wiring harness of new energy vehicles is a key component that connects high-voltage components. While transmitting electrical energy, they may also be affected by electromagnetic interference. In order to ensure the safe operation and system stability of new energy vehicles, anti-interference technology plays an important role in the design of high-voltage wiring harnesses.

[0003] After searching, the Chinese patent document announcement number: CN220085675U discloses a new energy vehicle anti-interference high-voltage wire harness, which relates to the field of anti-interference wire harness technology. In order to solve the problem that the existing wire harness will wrap a layer of anti-wave sleeve woven from oxygen-free copper wire on the outside of the wire harness for anti-interference, it is used to prevent the interference signal from entering the inner layer to interfere with the conductor. Since the anti-wave sleeve is closely attached to the wire harness, it will affect the heat dissipation of the wire harness, and high temperature will reduce the service life of the wire harness. The middle of the anti-interference wire harness is provided with a wire harness body; the anti-interference sleeve is arranged on the outside of the wire harness body, and the wire harness body and the anti-interference sleeve are nested and connected, the inner side of the anti-interference sleeve is provided with a fitting fixing sleeve, the inside of the fitting fixing sleeve is provided with a wire harness groove, and the anti-interference sleeve is provided with an alarm light bar; the heat dissipation sleeve is arranged between two adjacent fitting fixing sleeves, the inside of the heat dissipation sleeve is provided with a supporting inner groove, and the inside of the supporting inner groove is provided with support sheets around both sides.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 , Figure 2, an embodiment provided by the utility model: an anti-interference high-voltage wiring harness for new energy vehicles, including two wire groups 1, one of which is fixedly connected to a base 2 at the bottom, the base 2 can provide a stable support for the machine or equipment, ensuring its stability and safety during use, and the base 2 can be designed into various shapes and sizes to adapt to different application scenarios and load requirements, and optimize the overall structural design. The top of the base 2 is fixedly connected to an arc-shaped soft board 3, the outer wall of the arc-shaped soft board 3 is fixedly connected to a plurality of card blocks 4, the outer wall of the arc-shaped soft board 3 is fixedly connected to a push block 5, the top of the base 2 is fixedly connected to two arc-shaped soft boards 6, the inner wall of one of the arc-shaped soft boards 6 is fixedly connected to a plurality of card blocks 7, the outer wall of one of the arc-shaped soft boards 6 is fixedly connected to a push block 8, and the outer wall of the wire group 1 is fixedly connected to a hollow column 9. Since the inside is empty, the hollow column 9 is lighter than a solid column of the same diameter, which is very beneficial for structures that need to be lightweight. The inside of the hollow column 9 is fixedly connected with a disassembly component.

[0025] Reference Figure 3 , Figure 4 The disassembly assembly includes a shell 10. The shell 10 structure can withstand large loads with thinner materials because their geometric shape can effectively disperse force and reduce stress concentration. The shell 10 structure is usually lighter than a solid structure with the same load-bearing capacity, which is very beneficial for applications that require lightweighting. The inner wall of the shell 10 is fixedly connected to a spring 11, which can store energy and release it at the appropriate time. This feature makes it very useful in buffering impacts, absorbing vibrations, etc. The top of the shell 10 is rotatably connected to a special-shaped block 12, and a square opening 13 is opened on the left side of the special-shaped block 12. The outer wall of the hollow column 9 is slidably connected to a sliding column 14, and slots 15 are opened on both the upper and lower sides of the sliding column 14.

[0026] Reference Figure 2-Figure 4 , the inner wall of the arc-shaped soft board 1 3 contacts the outer wall of the line group 1, and the inner wall of one of the arc-shaped soft boards 2 6 contacts the outer wall of the line group 1. The outer wall of the arc-shaped soft board 3 contacts the outer wall of the arc-shaped soft board 2 6. The outer wall of the block 1 4 is engaged with the outer wall of the block 2 7, and the outer wall of the block 1 4 contacts the outer wall of the arc-shaped soft board 2 6. The outer wall of the block 2 7 contacts the outer wall of the arc-shaped soft board 3. The upper and lower sides of the hollow column 9 are fixedly connected to the inside with a shell 10. Since the structure of the shell 10 usually uses less material, it may have lower energy consumption and environmental impact during production and use. The top of the spring 11 is fixedly connected to the bottom of the special-shaped block 12. The mechanical behavior of the spring 11 is relatively easy to predict, and engineers can design the spring 11 through precise calculations to meet specific performance requirements. The outer wall of the square opening 13 is engaged with the inner wall of the slot 15, and the special-shaped block 12 contacts the inner wall of the slot 15.

[0027] Working principle: put the wire group 1 into the arc-shaped soft board 3, push the push block 5 to push the arc-shaped soft board 3, and the arc-shaped soft board 3 drives multiple clamping blocks 4 to be pushed into the inner wall of the arc-shaped soft board 6 and engage with the clamping block 7 for tightening. When maintenance or replacement is required, the arc-shaped soft board 3 can be pulled out by pulling the push block 28, thereby realizing the bundling and tightening. By tightening the wire harness, the occupied space can be reduced, making the installation more compact, which is especially suitable for applications with limited space. The tightened wire harness can reduce the wear caused by vibration or movement and extend the service life of the cable.

[0028] Push the hollow column 9 to push the hollow column 9 into the sliding column 14, push the hollow column 9 to drive the shell 10, push the shell 10 to drive the special-shaped block 12, push the special-shaped block 12 to push it into the sliding column 14, the special-shaped block 12 will compress the spring 11 to contract, the special-shaped block 12 is pushed into the groove 15, and the spring 11 rebounds to engage and clamp. When disassembly is required, press the special-shaped block 12 to make the spring 11 retract and pull it out to complete the disassembly. The detachable wiring harness design allows quick installation or replacement when needed, which improves work efficiency, especially in situations where space is limited or the wiring harness layout needs to be adjusted frequently. Since the wiring harness can be disassembled, it is easier to access and repair related components when a failure occurs or maintenance is required, reducing maintenance time and cost.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
