Description

Technical Field

[0001] This utility model relates to the field of new energy, and in particular to a high-voltage wiring harness for new energy vehicles. Background Technology

[0002] In new energy vehicles, whether hybrid or pure electric, the high-voltage system is a core component and its importance is self-evident. It carries the internal and external wiring harness connections of electric and hybrid vehicles, distributes power through the power distribution box, transmits electrical energy efficiently and with high quality through the high-voltage wiring harness, and shields external signal interference.

[0003] The existing technology has the following problems: In new energy vehicles under the existing technology, high-voltage wiring harnesses are high-safety components, and insulation materials are usually used to wrap the outside of the wires to prevent current leakage and short circuits. However, in actual use, due to external forces or material aging, the insulation material wrapped outside the wires will inevitably be damaged, which will lead to current leakage and short circuits, greatly affecting driving safety.

[0004] Therefore, we propose a high-voltage wiring harness for new energy vehicles to solve the above problems. Utility Model Content

[0005] This utility model provides a high-voltage wiring harness for new energy vehicles to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-voltage wiring harness for new energy vehicles, comprising a power battery and a mounting plate, wherein the mounting plate is fixedly mounted on the top of the power battery, and a high-voltage cable extends from the output end of the power battery, the high-voltage cable being fixedly mounted on the top of the mounting plate by a fixing component; the high-voltage cable comprises a wiring harness extending from the output end of the power battery and encased inside a housing, the wiring harness and the housing being fixedly mounted on the top of the mounting plate by a fixing component, the inner wall of the housing being provided with a sandwich layer, the sandwich layer being filled with a filling liquid, and the filling liquid being divided into sections by a partition provided inside the sandwich layer.

[0007] Preferably, the interval between each adjacent partition is not less than 0.5 cm.

[0008] Preferably, the interlayer is a dry vacuum cavity, and the filling liquid inside it is cyanoacrylate adhesive.

[0009] Preferably, the fixing component includes an upper cover plate and a lower cover plate, which are fitted together to cover the outer side of the outer shell. Threaded holes are provided at both ends of the upper cover plate and the lower cover plate. The upper cover plate and the lower cover plate are fitted with studs through the threaded holes at both ends to fix the outer shell to the top of the mounting plate.

[0010] Preferably, the cover plate and the lower cover plate have the same structure.

[0011] Preferably, the mounting plate includes a mounting shell, which is fixedly mounted on the top of the power battery. The top of the mounting shell is provided with a mounting platform, and the top of the mounting platform is provided with a mounting hole. The upper cover plate and the lower cover plate are mounted on the top of the mounting platform through threaded holes, studs, and mounting holes at the left and right ends, and the outer shell included inside them is fixed to the top of the mounting platform.

[0012] Preferably, the stud is threadedly connected to the mounting hole.

[0013] Preferably, the mounting holes correspond to the threaded holes opened at the left and right ends of the upper and lower cover plates.

[0014] The beneficial effects of this utility model are:

[0015] This invention features a high-voltage cable, which includes a housing that encloses the wire harness. An inner layer is provided on the inner wall of the housing, forming a dry, vacuum cavity filled with a liquid made of cyanoacrylate adhesive. When the housing is damaged, the cyanoacrylate adhesive flows out and is exposed to the air. Upon contact with trace amounts of moisture (humidity) in the air, it rapidly undergoes anionic polymerization, forming long polymer chains. Within seconds to tens of seconds, it transforms from a liquid to a solid, thus repairing the damaged area of ​​the housing.

[0016] The outer shell is wrapped inside the upper and lower cover plates. The upper and lower cover plates are installed on the top of the mounting platform through threaded holes, studs and mounting holes at the left and right ends, and the inner outer shell is fixed to the top of the mounting platform, thereby fixing the outer shell and preventing the cables from getting tangled and causing a short circuit.

[0017] This invention solves the problem that the insulation material wrapped around the outside of high-voltage wiring harnesses in the prior art is damaged in actual use due to external force or material aging, leading to current leakage and short circuit, thus greatly increasing driving safety.

[0025] The components include: power battery-1, mounting plate-2, high-voltage cable-3, fixing component-4, mounting shell-21, mounting platform-22, mounting hole-23, wire harness-31, outer shell-32, interlayer-33, filling fluid-34, separator-35, upper cover plate-41, lower cover plate-42, threaded hole-43, and stud-44. Detailed Implementation

[0026] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0027] like Figure 1 , 2 As shown in Figure 3, this utility model provides a high-voltage wiring harness for new energy vehicles, including a power battery 1 and a mounting plate 2. The mounting plate 2 is fixedly installed on the top of the power battery 1. The mounting plate 2 is used to fix the high-voltage cable 3 in conjunction with the fixing component 4. The high-voltage cable 3 extends from the output end of the power battery 1. The high-voltage cable 3 carries the internal and external wiring harness connections of electric and hybrid vehicles. The high-voltage cable 3 is fixedly installed on the top of the mounting plate 2 through the fixing component 4.

[0028] The high-voltage cable 3 includes a wire harness 31, which extends from the output end of the power battery 1. The wire harness 31 is used for internal and external wiring connections in electric and hybrid vehicles. The wire harness 31 is encased inside the housing 32, which protects the wire harness 31 installed inside and prevents current leakage and short circuits. The wire harness 31 and the housing 32 are fixedly installed on the top of the mounting plate 2 by a fixing component 4. The inner wall of the housing 32 is provided with a sandwich layer 33, which is used to store filling liquid 34. The sandwich layer 33 is filled with filling liquid 34, and the filling liquid 34 is divided into sections by a partition 35 inside the sandwich layer 33. When the housing 32 is broken due to aging or external force, the filling liquid 34 will flow out from the sandwich layer 33 and remain on the surface of the housing 32. When it encounters trace amounts of moisture (humidity) in the air, it will quickly undergo anionic polymerization to form long polymer chains. It can change from liquid to solid within a few seconds to tens of seconds, thereby repairing the damaged parts of the housing 32 and preventing current leakage and short circuits.

[0029] In this embodiment, the spacing between each adjacent partition 35 is not less than 0.5 cm. By setting the partition 35, the filling liquid 34 inside the interlayer 33 can be divided into sections, preventing the filling liquid 34 inside the interlayer 33 from flowing out completely when one part of the outer shell 32 is damaged. The spacing of not less than 0.5 cm ensures that the outer shell 32 can be repaired without causing excessive leakage of filling liquid 34.

[0030] The interlayer 33 is a dry, vacuum-sealed cavity filled with a cyanoacrylate adhesive, 34. This dry, vacuum-sealed cavity is used for long-term storage of the cyanoacrylate adhesive-based filler liquid 34. The cyanoacrylate adhesive has a unique curing mechanism, belonging to the moisture-curing type of adhesive. In the absence of moisture, the cyanoacrylate monomer is in a liquid state. When it comes into contact with trace amounts of moisture in the environment (such as water vapor in the air), it rapidly initiates a polymerization reaction, quickly transforming from a liquid to a solid state. This curing process is extremely rapid.

[0031] like Figure 4 , 5 As shown, the fixing component 4 of this utility model includes an upper cover plate 41 and a lower cover plate 42, which are fitted together to wrap around the outside of the outer shell 32. Threaded holes 43 are provided at both the left and right ends of the upper cover plate 41 and the lower cover plate 42. The upper cover plate 41 and the lower cover plate 42 are fitted with studs 44 through the threaded holes 43 at both ends to fix the outer shell 32 to the top of the mounting plate 2. In use, the upper cover plate 41 and the lower cover plate 42 are used to wrap around the outside of the outer shell 32. The studs 44 are fitted with the threaded holes 43 at both ends of the upper cover plate 41 and the lower cover plate 42 to tighten the upper cover plate 41 and the lower cover plate 42 to better wrap the outer shell 32. The studs 44 can also be fitted with the mounting holes 23 to fix the outer shell 32 wrapped by the upper cover plate 41 and the lower cover plate 42 to the top of the mounting platform 22.

[0032] The upper cover plate 41 and the lower cover plate 42 have the same structure. The same structure can increase the fit and reduce the cost of mold making for manufacturers, thereby increasing economic benefits.

[0033] like Figure 6 , 7 As shown, the mounting plate 2 of this utility model includes a mounting shell 21, which is used for installation and connection. The mounting shell 21 is fixedly installed on the top of the power battery 1. The top of the mounting shell 21 is provided with a mounting platform 22, which is used to fix the high-voltage cable 3 with the fixing device 4. The top of the mounting platform 22 is provided with a mounting hole 23, which is used to fix the outer shell 32 wrapped by the upper cover plate 41 and the lower cover plate 42 to the top of the mounting platform 22 with the stud 44. The upper cover plate 41 and the lower cover plate 42 are installed on the top of the mounting platform 22 through the threaded holes 43, studs 44 and mounting holes 23 at the left and right ends, and the outer shell 32 included inside them is fixed to the top of the mounting platform 22.

[0034] Among them, the stud 44 is threadedly connected to the mounting hole 23. Through the threaded connection between the stud 44 and the mounting hole 23, the outer shell 32 wrapped by the upper cover plate 41 and the lower cover plate 42 can be fixed to the top of the mounting platform 22.

[0035] The mounting hole 23 corresponds to the threaded holes 43 opened at the left and right ends of the upper cover plate 41 and the lower cover plate 42. The upper cover plate 41 and the lower cover plate 42 can be tightened by the studs 44 to better wrap the outer shell 32. The studs 44 can also pass through the threaded holes 43 and cooperate with the mounting hole 23 to fix the outer shell 32 wrapped by the upper cover plate 41 and the lower cover plate 42 to the top of the mounting platform 22.

[0036] Working principle:

[0037] A high-voltage cable 3 extends from the output end of the power battery 1, and the high-voltage cable 3 is fixedly installed on the top of the mounting plate 2 by a fixing component 4.

[0038] The high-voltage cable 3 includes a wire harness 31. The wire harness 31 and the outer shell 32 are fixedly installed on the top of the mounting plate 2 by the fixing component 4. When the outer shell 32 is broken due to aging or external force, the filling liquid 34 will flow out from the interlayer 33 and remain on the surface of the outer shell 32. When it encounters trace amounts of moisture (humidity) in the air, it will quickly undergo anionic polymerization reaction to form a long polymer chain. It can change from liquid to solid within a few seconds to tens of seconds, thereby repairing the damaged part of the outer shell 32 and preventing current leakage and short circuit.

[0039] The fixing component 4 includes an upper cover plate 41 and a lower cover plate 42. In use, the upper cover plate 41 and the lower cover plate 42 are placed opposite each other on the outside of the outer shell 32 and wrapped around it. Then, the bolts 44 are screwed into the threaded holes 43 opened at the left and right ends of the upper cover plate 41 and the lower cover plate 42. The upper cover plate 41 and the lower cover plate 42 will be tightened with the cooperation of the bolts 44 and the threaded holes 43, so that they can better wrap around the outer shell 32. Then, the bolts 44 will pass through the threaded holes 43 opened at the left and right ends of the lower cover plate 42 and cooperate with the mounting holes 23 to fix the outer shell 32 wrapped by the upper cover plate 41 and the lower cover plate 42 to the top of the mounting platform 22.

[0040] Mounting plate 2 includes mounting shell 21, which is used for installation and connection. During operation, bolts 44 will pass through threaded holes 43 at both ends of the lower cover plate 42 and engage with mounting holes 23 on the mounting platform 22 to fix the outer shell 32 enclosed by the upper cover plate 41 and the lower cover plate 42 to the top of the mounting platform 22.
