[0001] This utility model relates to the field of battery module technology, and in particular to a wire harness isolation plate assembly. Background Technology

[0002] Wiring harness separators are a crucial component of energy storage devices centered around battery modules. Their function is typically to isolate the battery cells from various wiring harnesses and other related electronic components. Currently, common wiring harness separators suffer from problems such as complex components, messy wiring, and low assembly efficiency. Furthermore, because different battery modules may have different terminal structures and connector configurations, wiring harness separators are often difficult to adapt to various battery module styles and their associated testing cables, resulting in high overall costs. Summary of the Invention

[0003] This utility model provides a wire harness isolation plate assembly that features clear wiring, easy assembly, and low cost. It includes an upper plate and a lower plate. The upper plate is used to fix an aluminum palladium and a power connector. The upper plate includes a head isolation sub-plate and a middle isolation sub-plate arranged sequentially along the X-direction. The head isolation sub-plate is used to fix the power connector, and the middle isolation sub-plate is used to fix the aluminum palladium. The lower plate includes a platform portion for fixing the wire harness and a channel portion for accommodating the wire harness. The wire harness is connected to the aluminum palladium and extends from the upper plate to the lower plate.

[0004] Furthermore, the head insulating sub-plate includes a first connecting portion, a second connecting portion, and a first hollow portion. The first connecting portion is disposed above the head insulating sub-plate and is used to connect with the battery module and the side cover plate. The second connecting portion is disposed on the side of the head insulating sub-plate and is used to accommodate the power connector. The first hollow portion is formed by hollowing out the back plate of the head insulating sub-plate along the Y direction and is used to accommodate the aluminum palladium.

[0005] Furthermore, the head isolation sub-plate also includes a first frame, which is formed by the back plate of the head isolation sub-plate protruding outward along the Y direction. The first frame is used to separate the head isolation sub-plate from the middle isolation sub-plate.

[0006] Furthermore, the central isolation sub-plate includes several isolation sub-units arranged side by side. Each isolation sub-unit has a second hollow portion for accommodating the aluminum palladium and a snap-fit ​​portion for fixing the aluminum palladium. The second hollow portion is obtained by hollowing out the back plate of the isolation sub-unit along the Y direction. The snap-fit ​​portion includes a buckle and a limiting block. The buckle is used to limit the aluminum palladium in the Z direction, and the limiting block abuts against the aluminum palladium from the Y direction upward and limits the aluminum palladium in the Y direction.

[0007] Furthermore, the central isolation sub-plate includes a second frame, which is disposed on the upper edge of the isolation sub-unit and one side of the isolation sub-unit. The second frame is used to separate two adjacent isolation sub-units and also to separate the isolation sub-unit from the head isolation sub-plate.

[0008] Furthermore, the upper plate also includes a tail isolation sub-plate, which is disposed in the X direction on the side of the middle isolation sub-plate away from the head isolation sub-plate, and the tail isolation sub-plate is fixed relative to the battery module and the side cover plate respectively.

[0009] Furthermore, the tail isolation sub-plate includes a third frame, which is formed by the back plate of the tail isolation sub-plate protruding outward along the Y direction. The third frame is disposed on the upper side, lower side and a side away from the middle isolation sub-plate of the tail isolation sub-plate, and the third frame is used to separate the tail isolation sub-plate from the middle isolation sub-plate.

[0010] Furthermore, the lower plate also includes a lower frame, which is located below the channel portion and is disposed on the lower edge and two sides of the lower plate. The lower frame is used to cover the lower plate from below.

[0011] Furthermore, it also includes a side cover plate, which is disposed along the Y direction outside the upper plate and the lower plate. The side cover plate is also integrally connected to the upper plate and the lower plate respectively. The side cover plate is used to cover the accommodating space formed by the upper plate, the lower plate and the side cover plate from the Y direction.

[0012] Furthermore, the platform includes a protrusion and a cable tie hole. The protrusion is formed by the back plate of the lower plate extending outward along the Y direction. The protrusion is used to provide a placement platform for the wire harness. The cable tie hole is opened in the middle of the protrusion, and the wire harness placed on the protrusion can be tied and fixed by a cable tie passing through the cable tie hole.

[0013] The wire harness isolation plate assembly provided by this utility model fixes an aluminum palladium and a power connector with electrical connection function through the upper plate and accommodates and fixes the wire harness through the lower plate. It utilizes the space inside the isolation plate to naturally form the wiring path, making the wire harness easy to organize and assemble. At the same time, the wire harness isolation plate assembly of this utility model has a simplified structure, which effectively reduces the production difficulty and production cost.

[0022] Please see Figures 1 to 2The wire harness separator assembly of this utility model is installed on the side of the battery module 6 where the terminal post is provided. It includes an upper plate 1, a lower plate 2 and a side cover 7. The upper plate 1 and the lower plate 2 are attached to the outside of the battery module 6 along the Y direction. The side cover 7 is disposed outside the upper plate 1 and the lower plate 2 along the Y direction. The wire harness 5 and the aluminum palladium 3 are disposed in the accommodating space formed by the upper plate 1, the lower plate 2 and the side cover 7. The upper plate 1 and lower plate 2 of this utility model are arranged sequentially and connected as a whole along the height direction of the battery module 6, i.e., the Z direction. The upper plate 1 is provided with a snap-fit ​​part 8 for fixing the aluminum palladium 3. The lower plate 2 is provided with a channel part 23 for accommodating the wire harness 5 and a platform part 22 for fixing the wire harness 5. The upper plate 1 includes a head isolation sub-plate 11, a middle isolation sub-plate 12 and a tail isolation sub-plate 13 arranged sequentially along the length direction of the battery module 6, i.e., the X direction. The head isolation sub-plate 11 is used to fix the power connector 4. The middle isolation sub-plate 12 is provided with a snap-fit ​​part 8. The tail isolation sub-plate 13 is used to fix relative to the battery module 6 and the side cover plate 7 respectively. Specifically, the upper plate 1, the lower plate 2, and the side cover 7 are fixed to the left side of the battery module 6. The power connector 4 is used to connect the power bus of the battery module 6. One power connector 4 is located at the corner of the front and left side of the battery module 6. At the other corner diagonally opposite to this corner, that is, at the corner of the rear and right side of the battery module 6, a power connector 4 is also provided. In other words, the battery module 6 in this embodiment has a centrally symmetrical structure. The upper plate 1, the lower plate 2, and the side cover 7 located on its left and right sides are also arranged in a centrally symmetrical manner. That is, the left and right sides of the battery module 6 are mirror-reversed structures. In this embodiment, the upper plate 1 and the lower plate 2 are integrally injection molded. The aluminum palladium 3 is the electrical connector of the battery module 6. The aluminum palladium 3 is fixed to the upper plate 1 through the snap-fit ​​part 8. The wire harness 5 is arranged in the Y direction in the accommodating space surrounded by the upper plate 1, the lower plate 2 and the side cover plate 7, and in the Z direction on the platform part 22 and the channel part 23 of the lower plate 2. The wire harness 5 can be naturally placed on the platform part 22 in the Z direction under the action of gravity, and then extend out of the accommodating space surrounded by the upper plate 1, the lower plate 2 and the side cover plate 7 from the channel part 23 of the lower plate 2 in the X direction. The tail isolation subplate 13 is provided with a first fixing hole 91 for connecting and fixing with the battery module 6 and a second fixing hole 92 for connecting and fixing with the side cover plate 7. The first fixing hole 91 is an elongated hole and the second fixing hole 92 is a round hole. In addition, in a preferred embodiment of the present invention, the wiring harness 5 is a data acquisition cable for collecting battery information. Therefore, one end of the wiring harness 5 is connected to the aluminum palladium 3 and extends from the upper plate 1 and is placed to the platform portion 22 of the lower plate 2. The other end of the wiring harness 5 extends from the channel portion 23 of the lower plate 2 and is connected to the BMS. In some other embodiments of the present invention, the wiring harness 5 may also be other cables with power supply or information transmission functions.This utility model uses an upper plate 1 to fix an aluminum palladium 3 with electrical connection function and a power connector 4, and a lower plate 2 to accommodate and fix a wire harness 5. The space inside the isolation plate naturally forms a wiring path, making the wire harness 5 easy to manage and assemble. At the same time, the wire harness isolation plate assembly structure in this utility model is simplified, effectively reducing production difficulty and production cost.

[0023] Please refer to the following: Figure 3Furthermore, the head isolation sub-plate 11 of this utility model includes a first frame 114, a first connecting part 111, a second connecting part 112, and a first hollow part 113. The first frame 114 is formed by the back plate of the head isolation sub-plate 11 protruding outward along the Y direction. The first frame 114 is disposed on the upper edge, lower edge, and one side adjacent to the middle isolation sub-plate 12 of the head isolation sub-plate 11. The first frame 114 is used to separate the head isolation sub-plate 11 from the middle isolation sub-plate 12. The first connecting part 111 is disposed above the head isolation sub-plate 11. The first connecting part 111 is formed by the head isolation sub-plate 11. The back plate extends upward along the Z direction. The first connecting part 111 is used to connect with the battery module 6 and the side cover plate 7. The second connecting part 112 is disposed on one side of the head isolation sub-plate 11 that is not provided with the first frame 114. The second connecting part 112 is used to accommodate the power connector 4. The first hollow part 113 is obtained by hollowing out the back plate of the head isolation sub-plate 11 along the Y direction. The first hollow part 113 is disposed in the middle of the back plate of the head isolation sub-plate 11 in the Z direction and in the X direction on the side of the back plate of the head isolation sub-plate 11 adjacent to the middle isolation sub-plate 12. The first hollow part 113 is used to accommodate the aluminum palladium 3.Specifically, in this embodiment, the first frame 114 includes a top plate, a vertical plate, and a bottom plate. The top plate of the first frame 114 is located at the upper edge of the head isolation sub-plate 11, the vertical plate of the first frame 114 is located on one side adjacent to the head isolation sub-plate 11 and the middle isolation sub-plate 12, and the bottom plate of the first frame 114 is located at the lower edge of the head isolation sub-plate 11. The bottom plate of the first frame 114 has a wire harness hole 51 for communicating with the channel portion 23 and for the wire harness 5 to pass through. The wire harness hole 51 is used to allow part of the wire harness 5 fixed on the platform portion 22 to pass through, so that part of the wire harness 5 enters the channel portion 23 from above in the Z direction. That is, the first frame 114 is located above the channel portion 23. The top and two sides of the first connecting portion 111 are surrounded by frame plates. The bottom of the first connecting portion 111 is separated from the first frame 114 by the top plate of the first frame 114. The first connecting portion 111 is provided with a first fixing hole 9 for connecting and fixing with the battery module 6. 1 and a second fixing hole 92 for connecting and fixing with the side cover plate 7, that is, the head isolation subplate 11 is fixed relative to the battery module 6 and the side cover plate 7 through the first connecting part 111. The first fixing hole 91 on the first connecting part 111 is located at the front end of the first connecting part 111 in the X direction, and the second fixing hole 92 on the first connecting part 111 is located at the rear end of the first connecting part 111 in the X direction. The second connecting part 112 is set at the opening of the first frame 114. This is because the power connector 4 in this embodiment is located at the corner of the front and left side of the battery module 6, so an opening is required on the left side for the power connector 4 and part of the wire harness 5 to extend out. The first hollow part 113 is used to accommodate the head aluminum palladium 3. The head aluminum palladium 3 is used to connect a single cell. Therefore, its size in the XZ plane is smaller than that of the aluminum palladium 3 on the middle isolation subplate 12. The polarity of the cell connected to the aluminum palladium 3 is opposite to that of the aluminum palladium 3 connected to the middle isolation subplate 12 located on one side of it.

[0024] Please refer to the following: Figure 5Furthermore, the middle isolation sub-plate 12 in this utility model includes a second frame 122 and an isolation sub-unit 12a. The second frame 122 is disposed on the upper edge of the isolation sub-unit 12a and on one side of the isolation sub-unit 12a. The second frame 122 is used to separate two adjacent isolation sub-units 12a. The second frame 122 is also used to separate the isolation sub-unit 12a from the head isolation sub-plate 11. Each isolation sub-unit 12a has a second hollow portion 121 for accommodating the aluminum palladium 3 and a snap-fit ​​portion 8 for fixing the aluminum palladium 3. The second hollow portion 121 is obtained by hollowing out the back plate of the isolation sub-unit 12a along the Y direction. The snap-fit ​​portion 8 is used to fix the aluminum palladium 3 in the second hollow portion 121 of the isolation sub-unit 12a. Specifically, in this embodiment, the second frame 122 includes a top plate and a vertical plate. The top plate of the second frame 122 is located at the upper edge of the isolation sub-unit 12a and is connected to the top plate of the first frame 114. The vertical plate of the second frame 122 is located on one side adjacent to the isolation sub-unit 12a. The lower edge of the second frame 122 does not have a frame plate, so the wire harness 5 connected to the aluminum palladium 3 inside the second frame 122 can fall directly from inside the second frame 122 to the channel portion 23 located below the second frame 122. The aluminum palladium 3 housed in the second hollow portion 121 is used to connect two cells with different polarities. Therefore, the size of the second hollow portion 121 in the XZ plane is approximately twice that of the first hollow portion 113. It is easy to understand that the number and arrangement of the isolation sub-units 12a can be adjusted according to the actual situation of the battery module 6.

[0025] Furthermore, the snap-fit ​​part 8 in this utility model includes a snap-fit ​​81 and a limiting block 82. The snap-fit ​​81 is disposed at the top and bottom of the middle isolation sub-plate 12. The snap-fit ​​81 is used to limit the aluminum palladium 3 in the Z direction to prevent the aluminum palladium 3 from sliding up and down. The limiting block 82 is protruding on the middle isolation sub-plate 12 in the Y direction. The limiting block 82 abuts against the aluminum palladium 3 from the Y direction upward to limit the aluminum palladium 3 in the Y direction. The snap-fit ​​81 can also abut against the aluminum palladium 3 from the Y direction after the aluminum palladium 3 is snapped in, so that the two ends of the limiting block 82 abut against the aluminum palladium 3 from the Y direction upward respectively, thereby fixing the aluminum palladium 3. Specifically, in this embodiment, a buckle 81 is provided on the top plate of the second frame 122, and two buckles 81 are provided at the bottom of the back plate of the isolation subunit 12a, that is, buckles 81 are provided above and below the second hollow part 121, thereby limiting the aluminum palladium 3 to the corresponding position of the second hollow part 121 in the Z direction; two limiting blocks 82 are provided on the side of the isolation subunit 12a near the vertical plate, that is, limiting blocks 82 are provided on both the left and right sides of the second hollow part 121. The limiting blocks 82 are used to abut against the aluminum palladium 3 from the inside in the Y direction, and the buckle 81 is used to abut against the aluminum palladium 3 from the outside in the Y direction, thereby limiting the aluminum palladium 3 to the corresponding position of the second hollow part 121 in the Y direction. This utility model installs the aluminum palladium 3 onto the upper plate 1 through the snap-fit ​​part 8, which is simple to operate and has a reliable fixing effect, greatly saving assembly time and labor costs.

[0026] Please refer to the following: Figure 4 Furthermore, the tail isolation subplate 13 in this utility model includes a third frame 131, which is formed by the back plate of the tail isolation subplate 13 protruding outward along the Y direction. The third frame 131 is disposed on the upper side, lower side and a side away from the middle isolation subplate 12 of the tail isolation subplate 13. The third frame 131 is used to separate the tail isolation subplate 13 from the middle isolation subplate 12. The tail isolation subplate 13 is provided with a first fixing hole 91 for connecting and fixing with the battery module 6 and a second fixing hole 92 for connecting and fixing with the side cover plate 7. The first fixing hole 91 on the tail isolation subplate 13 is located at the rear end of the tail isolation subplate 13 in the X direction and at the upper end of the tail isolation subplate 13 in the Z direction. The second fixing hole 92 on the tail isolation subplate 13 is located at the rear end of the first connecting part 111 in the X direction and below the first fixing hole 91 in the Z direction. Specifically, in this embodiment, the third frame 131 includes a top plate, a vertical plate, and a bottom plate. The top plate of the third frame 131 is located at the upper edge of the tail isolation sub-plate 13 and is connected to the top plate of the second frame 122. The vertical plate of the third frame 131 is located on a side away from the middle isolation sub-plate 12. The bottom plate of the third frame 131 is located at the lower edge of the tail isolation sub-plate 13 and is connected to the vertical plate of the second frame 122.

[0027] Furthermore, the lower plate 2 in this utility model also includes a lower frame 21, which is located below the channel portion 23. The lower frame 21 is disposed on the lower edge and two side edges of the lower plate 2, and is used to cover the space enclosed by the upper plate 1, the lower plate 2, and the side panels from below. Specifically, in this embodiment, the lower frame 21 includes a vertical plate and a bottom plate. The vertical plate of the lower frame 21 is located at the front and rear edges of the lower plate 2. The dimension of the vertical plate of the lower frame 21 in the Z direction is smaller than the dimension of the lower plate 2 in the Z direction. That is to say, openings are provided at both the front and rear ends of the lower plate 2, corresponding to the front and rear openings of the channel portion 23. The bottom plate of the lower frame 21 is located at the lower edge of the lower plate 2. Furthermore, the lower plate 2 is also provided with a first fixing hole 91 for connecting and fixing to the battery module 6 and a second fixing hole 92 for connecting and fixing to the side cover plate 7. The first fixing hole 91 on the lower plate 2 is located at the front and rear ends of the lower plate 2 in the X direction, and the second fixing hole 92 on the lower plate 2 is located at the lower end of the lower plate 2 in the Z direction. In this embodiment, a first fixing hole 91 is provided at the front end and the rear end of the lower plate 2, and a plurality of second fixing holes 92 are arranged at intervals at the lower end of the lower plate 2. This utility model connects and fixes the upper plate 1 and the lower plate 2 to the battery module 6 and the side cover plate 7 from multiple mounting points in the X and Y directions through a plurality of first fixing holes 91 and second fixing holes 92 located on the upper plate 1 and the lower plate 2, resulting in good installation effect, low difficulty, and low maintenance cost.

[0028] Furthermore, the platform portion 22 in this utility model includes a protrusion 221 and a cable tie hole 222. The protrusion 221 is formed by the back plate of the lower plate 2 protruding outward along the Y direction. The protrusion 221 is used to provide a platform for placing the wire harness 5. The cable tie hole 222 is opened in the middle of the protrusion 221, and the wire harness 5 placed on the protrusion 221 can be tied and fixed by a cable tie passing through the cable tie hole 222. Specifically, in this embodiment, several protrusions 221 are evenly distributed in the middle of the lower plate 2 and below the channel portion 23. The wire harness 5 led out from the upper plate 1 can fall naturally onto the protrusion 221 below the channel portion 23 under the action of gravity, and then be led out from the openings at both ends of the lower plate 2. This utility model places the wire harness 5 in the platform part 22 located below the channel part 23, so that the wire harness 5 naturally extends in the channel part 23 under the action of gravity, and then naturally leads out from the buckles 81 at both ends of the channel part 23. The wiring is beautiful and simple, saving assembly time.

[0029] In summary, the wire harness isolation plate assembly of this utility model fixes the aluminum palladium and power connector with electrical connection function in the upper plate and accommodates and fixes the wire harness in the lower plate. It utilizes the space inside the isolation plate to naturally form the wiring path, making the wire harness easy to manage and assemble. At the same time, the wire harness isolation plate assembly of this utility model has a simplified structure, which effectively reduces the production difficulty and production cost.
