Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the drawings; while "inside" and "outside" refer to the outline of the device.

[0036] First, please combine Figure 1 The present application provides a high-voltage power distribution unit. The high-voltage power distribution unit (PDU) is responsible for reasonably distributing the power output by the car battery or generator to various systems and devices to ensure that they have a stable power supply.

[0037] Please combine Figure 1 as well as Figure 2 The high-voltage power distribution unit includes: a cover plate assembly 100, an electrical assembly 200, a housing assembly 300 and a wiring harness assembly 500.

[0038] The cover plate assembly 100 includes a box cover 110 and a connector 120 installed on the box cover, wherein the connector 120 is used to be electrically connected to an external electrical device; and an electrical assembly 200 is used to be electrically connected to a battery pack and the connector 120 respectively.

[0039] That is, the high-voltage power distribution unit is electrically connected to the battery pack through the electrical component 200, and is electrically connected to external electrical equipment through the electrical component 200 and the connector 120. The external electrical equipment may be other required electrical structures of the vehicle, such as motors, air conditioning compressors, charging systems, etc., so as to realize the distribution of the power output by the battery pack.

[0040] The housing assembly 300 is connected to the box cover 110, and includes a bottom wall 310 and a frame 330. The bottom wall 310 and the box cover 110 are arranged opposite to each other along a first direction. The frame 330 is fixed between the box cover 110 and the bottom wall 310, and is used to support and strengthen the box cover 110 and the bottom wall 310, so that the housing assembly 300 has a greater supporting strength. At least part of the electrical assembly 200 is installed in the frame 330, so that the housing assembly 300 can provide better protection for the electrical assembly 200.

[0041] Please combine Figure 3 as well as Figure 4 The frame 330 is formed with a row line space 331 extending along the first direction, one end of the wiring harness assembly 500 is connected to the connector 120, and the other end thereof passes through the row line space 331 to be connected to the electrical component 200. The connector 120 is connected to the electrical component 200 through the wiring harness assembly 500, so that an external electrical device is electrically connected to the electrical component 200 through the connector 120.

[0042] There are many wire harnesses in the high-voltage distribution unit. In the related art, a frame is set in the box to reinforce the high-voltage distribution unit. However, since the frame occupies part of the space in the box, the wire harness in the high-voltage distribution unit needs to bypass the frame, resulting in messy wiring and difficult installation, maintenance and arrangement.

[0043] In the embodiment of the present application, the frame 330 is formed with a row line interval 331 extending along the first direction, one end of the wiring harness assembly 500 is connected to the connector 120, and the other end extends from one side of the electrical component and passes through the row line interval for connecting the electrical component. In this way, the other end of the wiring harness assembly extends from one side of the electrical component, and the wiring is concentrated on one side of the electrical component, which is convenient for operators to concentrate on arranging and arranging the wiring harness. In other words, one end of the wiring harness assembly 500 is connected to the connector 120, and the other end extends from the position of the box cover 110 to connect with the electrical component 200 located in the housing assembly 300, that is, the overall extension direction of the wiring harness assembly 500 is actually the first direction. In the embodiment of the present application, the row line interval 331 is configured to extend along the first direction, so that the wiring harness assembly 500 passes through the row line interval 331 and is connected to the electrical component without bypassing the frame from the side, so that the row line distance in the high-voltage distribution unit is short, the wiring is regular, and it is also convenient for installation, maintenance and arrangement.

[0044] In some embodiments, the housing assembly 300 further includes a side wall 340, opposite ends of which are respectively connected to the box cover 110 and the bottom wall 310, and the side wall 340 includes a first side wall 341 and a third side wall 343 arranged along a second direction, the second direction is perpendicular to the first direction, and the row spacing 331 is opened on the side of the frame 330 facing the first side wall 341, or the side of the frame 330 facing the third side wall 343. In other words, the row spacing 331 is provided on one of the side of the frame 330 facing the first side wall 341 and the side of the frame 330 facing the third side wall 343.

[0045] In these embodiments, the row spacing 331 is opened on the side of the frame 330 facing the first side wall 341, or, on the side of the frame 330 facing the third side wall 343, that is, the wiring harness assembly 500 is concentrated from one side, that is, from the electrical component 200 and the first side wall 341, or from the electrical component 200 and the third side wall 343, so that the wiring is neater.

[0046] Please combine Figure 1 In some embodiments, the row space 331 is opened on the side of the frame 330 facing the first side wall 341, and the first side wall 341 is provided with a second opening 342 opposite to the row space 331. The shell assembly 300 also includes a side cover 350, and the side cover 350 is used to cover the second opening 342.

[0047] In these embodiments, the other end of the wiring harness assembly extends from one side of the electrical component, the wiring is concentrated on one side of the electrical component, and the row line spacing 331 is also located on this side. That is, almost all of the wiring harness assembly can be routed from one side of the electrical component, and through the row line spacing 331 located on this side of the electrical component to connect the electrical component, which greatly reduces the wiring distance.

[0048] It is easy to understand that the wiring harness assembly 500 in the present application does not include all the wiring harnesses of the high-voltage power distribution unit, but includes most of the wiring harnesses of the high-voltage power distribution unit. Figure 2 It can be seen that most of the wiring harnesses of the high-voltage distribution unit are located on one side of the electrical components, so that there are only a small part or no wiring harnesses on the other side of the electrical components. This allows most of the wiring harnesses to be concentratedly wired and installed from one side of the electrical components, making the wiring inside the high-voltage distribution unit more neat and orderly.

[0049] The second opening 342 is covered or opened by the side cover 350. In this way, when inspecting, the side cover 350 is opened to expose the second opening 342 and the row line interval 331 arranged opposite to the second opening 342, so that the maintenance personnel can see the wire harness assembly 500 therein and can conveniently perform operations such as arranging, installing, replacing, and inspecting the wire harness assembly 500.

[0050] In some embodiments, the frame 330 includes a frame body 332 and a first connecting member 333 that are fixedly connected. The frame body 332 is fixedly connected to the side wall 340 .

[0051] In some examples, the outer contour of the high-voltage distribution unit can be a rectangular parallelepiped, and the box cover 110, the bottom wall 310, and the side wall 340 can be combined to form an installation space located inside the high-voltage distribution unit. The frame 330 is installed in the installation space, the frame 330 is located between the box cover and the bottom wall, the frame 330 is located between the side walls, and the frame 330 can be fixedly connected to the side wall 340. In addition, the frame 330 can also be fixedly connected to the bottom wall 310, and the frame 330 can also be fixedly connected to the box cover 110.

[0052] The main function of the frame 330 is to reinforce the high-voltage power distribution unit, making the high-voltage power distribution unit stronger and less likely to deform when subjected to a large force. The frame body 332 is the portion of the frame 330 that is close to the box cover 110, the bottom wall 310, and the side wall 340. The frame body 332 constitutes the outer contour of the entire frame 330 and can be a rectangular parallelepiped frame.

[0053] Please combine Figure 5 as well as Figure 6The frame 330 also includes a first connector 333 fixedly connected to the frame body 332. The first connector 333 is mainly arranged between the box cover 110 and the bottom wall 310. In addition, the internal space of the high-voltage distribution unit is divided by the first connector 333, so that a first installation cavity 610 is provided between the first connector 333 and the box cover 110, and a second installation cavity 630 is provided between the first connector and the bottom wall 310. Some electrical components 200 can be installed in the first installation cavity 610, such as Hall, copper busbar, etc., and some electrical components 200 can be installed in the second installation cavity 630, such as BMS, etc., so that a part of the electrical components 200 is installed in the first installation cavity, and a part of the electrical components 200 is installed in the second installation cavity. The first connector 333 is arranged close to the first side wall 341, and the first connector 333 is provided with a line interval 331, and the line interval 331 is used to connect the first installation cavity 610 with the second installation cavity 630. In this way, after the wiring harness assembly 500 connected to the electrical component 200 is connected to a part of the electrical component 200 in the first installation cavity 610, it can directly enter the second installation cavity 630 through the line spacing 331 to connect a part of the electrical component 200 in the second installation cavity 630. Alternatively, after one end of the wiring harness assembly 500 is connected to the connector 120 of the box cover, it passes through the first installation cavity 610 and the line spacing 331 along the first direction, enters the second installation cavity 630, and connects to the electrical component 200 located in the second installation cavity.

[0054] Specifically, the side wall 340 may also include a second side wall 344 and a fourth side wall 345 arranged along a third direction, that is, the first side wall 341, the second side wall 344, the third side wall 343, and the fourth side wall 345 are bent and connected in sequence, and the third direction is perpendicular to the second direction.

[0055] In some embodiments, the frame 330 may further include a second connector 334, which may be located between the cover 110 and the bottom wall 310. One end of the second connector 334 is fixed to the first connector 333, and the other end thereof extends toward the third side wall 343.

[0056] One end of the second connecting member 334 is fixedly connected to the first connecting member 333. At the same time, since the first connecting member 333 is arranged close to the first side wall 341, that is, one end of the second connecting member 334 is arranged close to the first side wall 341, the other end of the second connecting member 334 extends along a side close to the third side wall 343. In this way, by setting the second connecting member 334, the frame 330 can be reinforced along the second direction.

[0057] The other end of the second connecting member 334 extends along a side close to the third side wall 343, and can be fixedly connected to the frame body 332. In some examples, the second connecting member 334 and the frame body 332 can be welded. Alternatively, the second connecting member 334 can be fixedly connected to the frame body 332 by setting another connecting member in the middle, and in some examples, it can be welded.

[0058] In some embodiments, the frame 330 may further include a third connector 335. The third connector 335 may be specifically located between the box cover 110 and the bottom wall 310. One end of the third connector 335 is connected to an end of the second connector 334 close to the third side wall 343, and the other end thereof extends toward a direction close to the bottom wall 310 and is connected to an end of the frame body 332 close to the bottom wall. In some examples, the third connector 335 and the second connector 334 may be welded. In some examples, the third connector 335 and the frame body 332 may be welded. In this way, the third connector 335 is used to reinforce the portion where the second installation cavity 630 of the high-voltage power distribution unit is located along the first direction so that it is not easily deformed.

[0059] In some embodiments, the frame 330 further includes a fourth connector 336, one end of which is connected to the first connector 333, and in some examples, the fourth connector 336 and the first connector 333 may be welded. The other end thereof extends toward the direction close to the box cover 110 and is connected to one end of the frame body 332 close to the box cover 110. In some examples, the fourth connector 336 and the frame body 332 may be welded. In this way, the portion where the first installation cavity 610 of the high-voltage power distribution unit is located is reinforced along the first direction by the fourth connector 336 so that it is not easily deformed.

[0060] In some embodiments, there are multiple first connectors 333, and the multiple first connectors 333 extend along a third direction, which is perpendicular to the second direction, and a row line interval 331 is formed between two adjacent first connectors 333. The frame 330 also includes a fifth connector 337, and the two ends of the fifth connector 337 are respectively connected to the two adjacent first connectors 333. The first connector 333 is reinforced by the fifth connector 337, and the fifth connector 337 and the first connector 333 are arranged along the second direction. In this way, the fifth connector 337 will not block the row line interval 331 between the first connectors 333 along the first direction, so that the wiring harness assembly 500 has a smaller wiring distance.

[0061] In some embodiments, the fifth connecting member 337 includes a first arm 3371, a second arm 3373 and a third arm 3375. The opposite ends of the second arm 3373 are bent and connected with the first arm 3371 and the third arm 3375 respectively. The end of the first arm 3371 away from the second arm is fixedly connected to one of the two adjacent first connecting members 333, and the end of the third arm 3375 away from the second arm 3373 is fixedly connected to the other of the two adjacent first connecting members 333. In this way, the two adjacent first connecting members 333 can be reinforced, so that the row interval 331 can be stably set and not easily deformed. Along the second direction, the second arm 3373 is spaced from the first connecting member 333. In this way, the wiring harness assembly 500 can be avoided, which is convenient for the installation and arrangement of the wiring harness assembly 500.

[0062] Please combine Figure 5 as well as Figure 6 In some embodiments, the fifth connecting member further includes a fourth arm 3377, one end of which is fixedly connected to the first arm 3371, and the other end of which is connected to the side of the first connecting member 333 facing the bottom wall 310. In this way, the bottom of the first connecting member 333, that is, the side of the first connecting member 333 facing the bottom wall 310, is supported by the fourth arm 3377.

[0063] The first arm 3371, the second arm 3373, the third arm 3375 and the fourth arm 3377 of the fifth connecting member can reinforce the bottom and the side of the first connecting member 333, so that the first connecting member 333 is installed more stably and is not easy to deform, so that the row line interval 331 can be stably arranged and is not easy to deform. In addition, the fifth connecting member will not block the row line interval 331 along the first direction, which is convenient for wiring.

[0064] In a second aspect, a vehicle is also provided, the vehicle comprising the above-mentioned high-voltage power distribution unit.

The frame is fixed between the box cover and the bottom wall to support and strengthen the box cover and the bottom wall, so that the housing assembly has greater support strength.
