[0028] The following description, in conjunction with the accompanying drawings, details the wiring structure assembly applied to the cylinder block, the power system, and the automobile provided in this application through specific embodiments and application scenarios.

[0029] like Figures 1 to 4As shown in the embodiment of this application, a wiring structure assembly applied to a cylinder block 400 is disclosed. A separator 500 is provided within the cylinder block 400 to separate a dry chamber 401 and a wet chamber 402 within the cylinder block 400. The separator 500 is provided with a first wire-passing hole 501. The wiring structure assembly includes: Cable routing device 100 is used to connect with separator 500 to seal the gap between the first cable hole 501 and cable routing device 100. Cable routing device 100 is provided with through hole 101 corresponding to the first cable hole 501. The inner wall of through hole 101 is formed with first sealing protrusion 111 distributed along its own circumference.

[0030] For example, please refer to Figure 10 The cable tray 100 can be connected to the side of the separator 500 facing the wet cavity 402, in which case the through hole 101 is opposite to and communicates with the first cable passage hole 501; or, the cable tray 100 can also be connected to the side of the separator 500 facing the dry cavity 401, in which case the through hole 101 is opposite to and communicates with the first cable passage hole 501; or, the cable tray 100 can also be disposed inside the first cable passage hole 501, in which case the through hole 101 is located inside the first cable passage hole 501.

[0031] Cable 200 includes a cable core 210 and an insulating sleeve 220. The cable core 210 passes through the insulating sleeve 220, and a water-blocking material 230 is filled between the cable core 210 and the insulating sleeve 220. The insulating sleeve 220 passes through a through hole 101 and is connected to a first sealing protrusion 111. For example, the cable 200 here can be an anti-siphon cable, and the water-blocking material 230 can be a sealant.

[0032] In this application, the cable assembly includes a cable tray 100 and a cable 200. The cable 200 includes a cable core 210 and an insulating sleeve 220. The cable core 210 passes through the insulating sleeve 220, and a water-blocking material 230 is filled between the cable core 210 and the insulating sleeve 220. The water-blocking material 230 prevents liquid in the wet cavity 402 from seeping into the dry cavity 401 through the gap between the cable core 210 and the insulating sleeve 220. Furthermore, the cable tray 100 is provided with a through hole 101. The inner wall of the through hole 101 forms a first sealing protrusion 111 extending circumferentially. The insulating sleeve 220 passes through the through hole 101 and is connected to the first sealing protrusion 111 to seal the gap between the insulating sleeve 220 and the through hole 101. This prevents liquid in the wet cavity 402 from seeping into the dry cavity 401 through the gap between the cable 200 and the cable tray 100.

[0033] Furthermore, the cable 200 of this application can be directly passed from the wet cavity 402 through the cable tray 100 into the dry cavity 401. In other words, the cable 200 of this application is an integral cable, which is a single continuous body. There is no need to use connectors to segment the cable 200 in the middle, thereby ensuring that the cable 200 has better electrical performance. Therefore, after using the cable assembly of this application to connect the electrical components in the dry cavity 401 and the wet cavity 402, the stability of the electrical connection of the electrical components in the dry and wet cavities 402 can be improved.

[0034] In one alternative embodiment, the water-blocking material 230 extends from one end of the insulating sleeve 220 to the other end of the insulating sleeve 220.

[0035] In this embodiment, the water-blocking material 230 extends from one end of the insulating sleeve 220 to the other end of the insulating sleeve 220. That is, the extension length of the water-blocking material 230 is approximately equal to the extension length of the insulating sleeve 220. The water-blocking material 230 has a large extension length, and the length of the water-blocking material 230 is proportional to its water-blocking performance. Therefore, this embodiment can further prevent liquid in the wet cavity 402 from leaking into the dry cavity 401 through the gap between the insulating sleeve 220 and the cable core 210.

[0036] Of course. In other embodiments, the water-blocking material 230 may only be provided in a local area of ​​the cable 200 along its own extension direction. In this case, the water-blocking material 230 extends a smaller length. This application does not limit the extension length of the water-blocking material 230.

[0037] Please see Figure 3 and Figure 4 In one alternative embodiment, the number of first sealing protrusions 111 includes a plurality of first sealing protrusions 111, which are distributed at intervals along the axial direction of the through hole 101.

[0038] In this embodiment, multiple first sealing protrusions 111 are distributed at intervals along the axial direction of the through hole 101, so that multiple seals can be formed between the cable 200 and the through hole 101, improving the sealing reliability and further preventing liquid in the wet cavity 402 from leaking into the dry cavity 401 through the gap between the cable 200 and the through hole 101.

[0039] Of course, the number of first sealing protrusions 111 may also include only one, and this application does not limit this.

[0040] Please see Figure 4In one optional embodiment, the cable routing device 100 includes a connected seal 110 and a support 120. The seal 110 is elastic, and a through hole 101 is provided in the seal 110. The support 120 has a stiffness greater than that of the seal 110. A portion of the support 120 is embedded in the seal 110, and the portion of the support 120 embedded in the seal 110 surrounds the through hole 101. For example, the support 120 may include an insert 122, which is embedded in the seal 110 and surrounds the through hole 101. It should be noted that the first sealing protrusion 111 is part of the seal 110, and the two are integrally formed.

[0041] If the support member 120 is not embedded in the seal member 110, when the cable 200 passes through the through hole 101, the cable 200 will exert a compressive force on the seal member 110. Since the seal member 110 is elastic as a whole, this compressive force will cause the seal member 110 to deform as a whole. This will cause most of the sealing material to be squeezed to areas that do not need to be sealed, such as the outer edge of the seal member 110, resulting in force dispersion.

[0042] In this embodiment, a portion of the support member 120 is embedded in the seal member 110, and the portion of the support member 120 embedded in the seal member 110 is arranged around the through hole 101. The portion of the support member 120 surrounding the seal member 110 restricts the outward expansion of the sealing material and prevents the sealing material from being squeezed to the outer edge of the seal member 110. Therefore, when the cable 200 passes through the through hole 101, most of the sealing material is restricted between the through hole 101 and the portion of the support member 120 embedded in the seal member 110, thereby increasing the squeezing force of the seal member 110 on the cable 200 and improving the sealing performance between the first sealing protrusion 111 and the cable 200.

[0043] Please see Figure 1 and Figure 2 In an optional embodiment, the cable tray 100 further includes a base 130 for connection with the separator 500. The base 130 has a through mounting portion, and the support member 120 and the seal member 110 are both disposed in the mounting portion. The seal member 110 is connected to the mounting portion.

[0044] Since the support 120 and the seal 110 are usually integrally formed by vulcanization, the seal 110 and the support 120 need to be small in size when vulcanization is used. The small size of the seal 110 and the support 120 makes it difficult to integrate other functional components on them.

[0045] In this embodiment, the cable tray 100 also includes a base 130, on which a mounting part is provided. The support member 120 and the sealing member 110 are both located in the mounting part. The base 130 and the sealing member 110 are two separate structural components. Therefore, the base 130 is not limited by the shape of the sealing member 110 during vulcanization. The base 130 can form a larger external size during the molding process, which is conducive to setting other functional components, such as three-phase copper busbars, so that the cable tray 100 has greater functions.

[0046] Of course, in some other embodiments, the cable tray 100 may not include the base 130, in which case the seal 110 may be connected to the separator 500, and this application does not limit this. In yet another embodiment, the cable tray 100 may not include the base 130 and the support 120, but only include the seal 110, in which case the seal 110 is connected to the separator 500, and this application does not limit this.

[0047] Please see Figure 3 and Figure 4 In one optional embodiment, the outer peripheral wall of the seal 110 is formed with a second sealing protrusion 112 distributed circumferentially thereon. The second sealing protrusion 112 is connected to the mounting portion and is used to seal the gap between the seal 110 and the mounting portion. It should be noted that the seal 110 can be arranged in the same direction as the support 120. Figure 8 The second sealing protrusion 112 can be compressed in a direction perpendicular to the above-mentioned arrangement direction (as indicated by the arrow in the middle); Figure 8 It is compressed in the direction indicated by the arrow in the middle (y).

[0048] In this embodiment, a second sealing protrusion 112 is formed on the outer peripheral wall of the seal 110. That is, the second sealing protrusion 112 is part of the seal 110 and is integrally formed with the seal 110. In this way, the seal 110 can be placed in the mounting part to achieve a sealing fit between the seal 110 and the mounting part without the need to additionally fit a sealing ring on the outer peripheral surface of the seal 110, thereby simplifying the installation process. In addition, the integral forming of the second sealing protrusion 112 and the seal 110 can eliminate the assembly interface between parts, thereby forming a seamless structure between the second sealing protrusion 112 and the seal 110, preventing liquid leakage from the second sealing protrusion 112 and the seal 110.

[0049] Please see Figures 5 to 8 In one alternative embodiment, the cable tray 100 includes a seal 110 and a support 120 connected together, the seal 110 being elastic, and a through hole 101 being provided in the seal 110.

[0050] The support member 120 and the sealing member 110 are distributed sequentially along the axial direction of the through hole 101. The support member 120 is provided with a wire groove 102. The wire groove 102 and the through hole 101 are arranged sequentially and connected along the axial direction of the through hole 101. The insulating sleeve 220 passes through the wire groove 102.

[0051] In this embodiment, the support member 120 and the sealing member 110 are distributed sequentially along the axial direction of the through hole 101. The support member 120 is provided with a wire groove 102. The wire groove 102 and the through hole 101 are distributed sequentially along the axial direction of the through hole 101. In this way, the insulating sleeve 220 can be simultaneously inserted into the wire groove 102 and the through hole 101 to increase the support length of the cable tray 100 for the cable 200. Thus, the stress on the cable 200 will be distributed on a longer path, reducing the risk of damage to the cable 200 or the cable tray 100.

[0052] Of course, in other embodiments, the support member 120 may also be fitted outside the seal member 110, and this application does not limit this.

[0053] Please see Figure 5 and Figure 6 In an optional embodiment, the cable routing device 100 further includes an adhesive 140, at least a portion of which fills the cable passage 102 to fix the relative position between the cable 200 and the support member 120. It should be noted that adhesive liquid can be injected into the cable passage 102, allowing it to solidify and form the adhesive 140. After solidification, the adhesive liquid will form a second cable passage hole 141 surrounding the cable 200.

[0054] In this embodiment, the cable routing device 100 also includes an adhesive 140. The cable groove 102 is filled with the adhesive 140, thereby fixing the cable 200 in the cable groove 102. When the cable 200 is subjected to external force, the adhesive 140 can prevent the portion of the cable 200 located in the cable groove 102 from moving relative to the support member 120, thereby maintaining the position between the cable 200 and the first sealing protrusion 111. This prevents the cable 200 from repeatedly rubbing against the first sealing protrusion 111, which would cause a decrease in the sealing performance of the first sealing protrusion 111. Furthermore, the cable 200 and the first sealing protrusion 111 do not move relative to each other, and the sealing interface between them is always under static conditions. In this way, the pressure applied by the sealing member 110 to the cable 200 is maintained, ensuring the sealing effect between them.

[0055] Please see Figure 1 , Figure 5 and Figure 6 In an optional embodiment, the cable tray 100 further includes a base 130 for connection with the separator 500, and the base 130 has a through mounting portion.

[0056] The support member 120 includes a frame 121 and a wire threading part 123. The frame 121 and the sealing member 110 are both located in the mounting part. At least one of the sealing member 110 and the support member 120 is connected to the mounting part. The sealing member 110 is connected to the frame 121 and is distributed sequentially along the axial direction of the through hole 101. The frame 121 is arranged around the wire threading part 123. The wire threading part 123 is provided with a wire threading groove 102.

[0057] The frame 121 is provided with a through opening 103, which extends from the outer peripheral surface of the frame 121 to the inner peripheral surface of the frame 121. The adhesive 140 fills the frame 121, and a portion of the adhesive 140 fills the through opening 103 to bond the support member 120 to the base 130.

[0058] In this embodiment, the adhesive 140 fills the frame 121, and the wire-passing portion 123 with the wire-passing groove 102 is located inside the frame 121. Therefore, the adhesive 140 can fix the cable 200 inside the wire-passing groove 102, preventing the portion of the cable 200 located inside the wire-passing groove 102 from moving relative to the support member 120. Furthermore, a portion of the adhesive 140 fills the through-hole 103, and the inner wall of the mounting portion of the base 130 is exposed to the through-hole 103. The adhesive 140 located inside the through-hole 103 can adhere to the inner wall of the mounting portion. Since the first portion of the adhesive 140 located inside the frame 121 adheres to the frame 121 and the wire-passing portion 123, and the first portion also adheres to the second portion of the adhesive 140 located inside the through-hole 103, and the second portion adheres to the inner wall of the mounting portion, the adhesive 140 can adhere and fix the support member 120 to the inner wall of the mounting portion. As can be seen, the adhesive 140 in this embodiment can not only fix the relative position between the cable 200 and the threading part 123, but also fix the support 120 to the base 130, thus achieving the purpose of two uses in one.

[0059] Of course, in other embodiments, the base 130 and the support 120 can also be connected by snap-fit, welding, screw connection or other means, and this application does not limit this.

[0060] Please see Figure 1 In one optional embodiment, the cable tray 100 is provided with a plurality of through holes 101 spaced apart, and there are multiple cables 200, each cable 200 passing through a respective through hole 101.

[0061] The cable routing assembly also includes a first cable bundle sleeve 310 and a second cable bundle sleeve 320. The first cable bundle sleeve 310 is fitted outside the multiple cables 200, and the second cable bundle sleeve 320 is fitted outside the multiple cables 200. Along the extension direction of the cables 200, the first cable bundle sleeve 310 and the second cable bundle sleeve 320 are located on both sides of the cable routing device 100.

[0062] In this embodiment, the first cable bundle sleeve 310 and the second cable bundle sleeve 320 are fitted over multiple cables 200, which can bind the multiple scattered and messy cables 200 into a single, neat, and orderly cable bundle, making the direction and path of the cables 200 clear at a glance. Furthermore, the first cable bundle sleeve 310 and the second cable bundle sleeve 320 can isolate the cables 200 from the cylinder body 400, preventing friction between the cables 200 and the cylinder body 400 and reducing the risk of damage to the cables 200.

[0063] Please see Figure 9 In one optional embodiment, the insulating sleeve 220 includes an outer insulating sleeve 221 and an inner insulating sleeve 222. The outer insulating sleeve 221 is fitted over the inner insulating sleeve 222. The cable core 210 passes through the inner insulating sleeve 222. Water-blocking material 230 is filled between the cable core 210 and the inner insulating sleeve 222. The outer insulating sleeve 221 passes through the through hole 101 and is connected to the first sealing protrusion 111.

[0064] In this embodiment, the insulating sleeve 220 includes an outer insulating sleeve 221 and an inner insulating sleeve 222. The two insulating sleeves 220 can increase the thickness of the insulating medium and the creepage distance, thereby improving the electrical strength of the cable 200.
