[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0034] In the description of the present disclosure, “plurality” means at least two, such as two, three or more, etc., unless otherwise clearly and specifically defined.

[0035] Figure 1 It is a three-dimensional schematic diagram of an embodiment of a wire harness isolation plate of the present invention.

[0036] The wire harness isolating plate of the present invention can be installed on a battery module to form a battery pack, and the wire harness isolating plate is used to organize and isolate the wire harnesses connecting the battery module.

[0037] from Figure 1 It can be seen from the embodiments that the wiring harness isolation plate 11 of the present invention includes a bottom wall 14, an edge side wall 13, a wiring harness space 2 and a bus space 3, the edge side wall 13 is arranged on both side edges of the bottom wall 14, and the wiring harness space 2 and the bus space 3 are provided between the inner side surface of the edge side wall 13 and the top surface 15 of the bottom wall 14.

[0038] exist Figure 1 In the embodiment, the busbar spaces 3 are arranged along the edge side walls 13 on both sides from one end to the other end of the bottom wall 14, and two rows of busbar spaces 3 are arranged opposite to the two rows of busbar spaces 3 on both sides in the middle of the bottom wall 14, and the wiring harness space 2 is arranged between every two rows of oppositely arranged busbar spaces 3. The arrangement of the wiring harness space 2 and the busbar space 3 along the edge side walls 13 reasonably utilizes and regularizes the space of the wiring harness isolation plate 11 to regularize the routing of the wiring harness.

[0039] The number of columns of the busbar space 3 is not limited and can be as follows Figure 1 The four rows in the embodiment may also be one row or more rows, as long as a wiring harness space 2 is provided between every two rows of busbar spaces 3. Figure 1 In the embodiment, the bus space 3 is arranged in a straight line along the edge side walls 13 on both sides. Optionally, in other embodiments, the bus space 3 can also be arranged from one end of the bottom wall 14 to the other end along other lines such as oblique lines and curves.

[0040] According to the embodiment in the figure, a supporting bracket 8 may be further provided on the outer side of the edge side wall 13 near the bottom. The supporting bracket 8 forms an angle with the edge side wall 13 for supporting the wire harness between two adjacent wire harness isolation plates 11.

[0041] Furthermore, a shielding bracket 9 is provided on the outer side surface of the edge side wall 13 near the top, and the shielding bracket 9 can limit the wiring harness between two adjacent wiring harness isolation plates 11 on the sides from the top and shield external dust at the same time.

[0042] from Figure 1 It can also be seen from the embodiment that the edge side walls 13 on both sides extend toward the top surface 15 and the bottom surface 16 of the bottom wall 14 respectively. The portion of the edge side wall 13 extending out of the bottom surface 16 can limit the wiring harness isolation plate 11 from both sides when installed with the battery module to ensure that the wiring harness isolation plate 11 is connected to the battery module, prevent welding interference between the wiring harness isolation plate 11 and the battery module, and avoid offset during welding.

[0043] It should be noted here that the wiring harness isolation plate 11 is made of insulating material, that is, the bottom wall 14 and the edge side wall 13 are both made of insulating material, which can provide insulation protection for the battery cells of the battery module to prevent the wiring harness and other objects from damaging the blue film on the surface of the battery cells.

[0044] The wiring harness isolation plate 11 can be formed by integral injection molding, thereby maintaining the integrity of the wiring harness isolation plate 11 and facilitating its installation and removal from the battery module. In other embodiments, the wiring harness isolation plate 11 can also be formed by assembling multiple modules to flexibly set the layout of the wiring harness space 2 and the bus space 3 in the wiring harness isolation plate 11.

[0045] Figure 2 for Figure 1 A partial enlarged view of an embodiment of a center harness isolation plate showing the harness space.

[0046] Combination Figure 1 It can be seen that the harness space 2 is provided with a harness fixing device 5, which includes a boss 4 and a harness fixing member 51. The boss 4 is provided in the middle of the harness space 2 in the horizontal direction, and a harness channel 18 is formed on both sides of the boss 4. The harness can pass through the harness channel 18 from one end of the harness isolation plate 11 to the other end of the harness isolation plate 11 (such as Fig.13 as shown).

[0047] The harness fixing member 51 is installed on both sides of the boss 4. The figure shows the assembly process of the harness fixing member 51 and the boss 4. The harness fixing member 51 is used to limit the harness located in the harness channel 18 from the top.

[0048] from Figure 2It can be seen that a pressure relief port 21 can also be provided in the harness space 2. Multiple bosses 4 and the pressure relief port 21 are spaced apart from each other at the bottom wall 14. The pressure relief port 21 serves as a pressure relief outlet for the battery cells of the battery pack. The bosses 4 and the harness fixture 51 limit the harness within the harness channel 18. The bosses 4 and the pressure relief port 21 are spaced apart from each other, and the position of the harness can be limited from both ends of the pressure relief port 21 to prevent the harness from entering the pressure relief port 21 and blocking the pressure relief port 21, thereby ensuring that the pressure relief port 21 remains unobstructed.

[0049] Figure 3 The diagram is a schematic diagram of a pressure relief port of an embodiment of a wire harness isolation plate of the present invention.

[0050] from Figure 3 It can be seen from the embodiment that the pressure relief port 21 is a through hole, and the pressure relief port 21 is used for pressure relief of the battery module. An avoidance groove 22 is provided at the edge of the pressure relief port 21, and the avoidance groove 22 is lower than the top surface of the bottom wall 14, and is used to prevent the wiring harness from blocking the pressure relief port 21 and hindering the pressure relief of the battery cell. When the irregular wiring harness approaches the edge of the pressure relief port 21, the avoidance groove 22 can block the tendency of the wiring harness to enter the pressure relief port through the sunken groove.

[0051] Alternatively, if Figure 3 In the embodiment, multiple layers of sunken avoidance grooves 22 may be provided to form steps, that is, the avoidance grooves near the edge of the pressure relief port 21 are lower than the avoidance grooves above them, so as to increase the sliding resistance of the wire harness toward the pressure relief port 21, thereby preventing the wire harness from continuing to slide toward the pressure relief port 21 and preventing the wire harness from blocking the pressure relief port 21. The edge of the avoidance groove 22 near the pressure relief port 21 may also be provided with a retaining edge (not shown in the figure), which may further prevent the wire harness from sliding.

[0052] Figure 4 The present invention is a schematic diagram of a wire harness fixing member of a wire harness fixing device of an embodiment of a wire harness isolation plate of the present invention.

[0053] from Figure 4 As can be seen from the embodiment, the harness fixing member 51 has a first surface 58 and a second surface 57, combined with Figure 1 It can be seen that the wire harness fixing part 51 can be installed on both sides of the boss 4, and the second surface 57 of the wire harness fixing part 51 is a plane. When the wire harness fixing part 51 is installed on the boss 4, the second surface 57 of the wire harness fixing part 51 does not exceed the height of the edge side wall 13, thereby making the top surface of the wire harness isolation plate flat.

[0054] The first surface 58 of the wiring harness fixing piece 51 is provided with a wiring harness limiting portion 54 and a boss connecting portion 52. The boss connecting portion 52 is located on one side of the first surface 58 of the wiring harness fixing piece 51, and a clamping portion 53 is provided at the end of the boss connecting portion 52. The clamping portion 53 can be flexibly and conveniently clamped or disassembled on the boss 4.

[0055] according to Figure 4 In the embodiment, the clamping portion 53 may be a cylinder, which may be movably clamped to the boss 4, so that the harness fixing member 51 may be turned around the cylinder as the center, thereby adjusting the position of the harness fixing member 51 to better limit the position of the harness. Figure 4 As shown, the two ends of the boss connecting portion 52 extend outward, so that it can be more conveniently installed on the boss 4, and the wiring harness fixing member 51 can be more flexible to flip. The shape of the clamping portion 53 can be, but not limited to, a cube, an elliptical column, etc., as long as it can be clamped on the boss 4.

[0056] The harness stopper 54 is protruding from the first surface 58, and is used to cover the harness channel 18 from the top, thereby limiting the harness located in the harness channel 18 and shielding dust. The cross-sectional shape of the harness stopper 54 can be as follows: Figure 4 The illustrated shape is semicircular to match the outer surface shape of the wire harness, so as to better limit the wire harness from the top. The cross-sectional shape of the wire harness limiting portion 54 is not limited, and can also be square, trapezoidal, etc., as long as the wire harness can be limited.

[0057] according to Figure 4 In the embodiment, the other side of the first surface 58 of the wiring harness fixing member 51 may further be provided with a side wall connecting portion 56, which is used to connect with the first side wall 34 (such as Figure 6 Specifically, the side wall connecting portion 56 is provided with an elastic buckle 55, and the elastic buckle 55 can be snapped into or removed from the bus space 3.

[0058] from Figure 4 It can also be seen from the embodiment that there is a first gap 59 between the side wall connecting portion 56 and the wire harness limiting portion 54. The first gap 59 is a preset margin of the wire harness limiting portion 54. The wire harness limiting portion 54 can be set according to the outer contour shape and size of the wire harness, so that the first gap 59 can be large or small or even no gap is set, so as to ensure that the wire harness limiting portion 54 can better fix the position of the wire harness.

[0059] Figure 5 The present invention is a schematic diagram of a boss of a wire harness fixing device of an embodiment of a wire harness isolation plate of the present invention.

[0060] Combination Figure 1 It can be seen that the boss 4 is fixed to the bottom wall 14. Figure 5 As can be seen in the embodiment, the two sides of the boss 4 are provided with a first clamping groove 41, and the cross-sectional width of the top opening 45 of the first clamping groove 41 is smaller than the cross-sectional diameter of the bottom groove 43 thereof. Figure 2 and Figure 4It can be seen that the first engaging groove 41 is used to engage the engaging portion 53 of the wiring harness fixing member 51 .

[0061] The cross section of the bottom groove 43 of the first clamping groove 41 can be as follows Figure 5 The embodiment is circular to fit the cylindrical clamping portion 53. The cross-sectional shape of the bottom groove 43 is not limited, and may also be, for example, square, oval, etc., to fit the clamping portion 53 of different shapes.

[0062] according to Figure 5 In the embodiment, the top opening 45 of the boss 4 may further be provided with a notch 42, combined with Figure 4 It can be seen that the notch 42 is used to accommodate the end of the boss connection portion 52. The notch 42 can make the wire harness fixture 51 more firmly clamped to the boss 4, and the notch 42 can limit the boss connection portion 52 to the edge of the notch 42 when the wire harness fixture 51 is turned over, so as to limit the rotation angle of the boss connection portion 52, thereby limiting the turning angle of the wire harness fixture 51, and further allowing the wire harness fixture 51 to better limit the wire harness.

[0063] Figure 6 This is a partial enlarged view of an embodiment of the wire harness isolation plate of the present invention, showing the busbar space.

[0064] from Figure 6 It can be clearly seen from the embodiment that the harness space 2 is arranged between two rows of busbar spaces 3, and a first side wall 34 is arranged on the side of the busbar space 3 close to the harness space 2, and the first side wall 34 is provided with a first mounting hole 38. The elastic buckle 55 of the side wall connecting portion 56 of the harness fixture 51 can be mounted on the first mounting hole 38, so that the harness fixture 51 is installed in the busbar space 3, thereby fixing the position of the harness fixture 51 and limiting the position of the harness more firmly. Pressing the elastic buckle 55, the elastic buckle 55 can be removed from the first mounting hole 38, so that the harness fixture 51 is removed from the busbar space 3.

[0065] It can be understood that the boss connection portion 52 of the wire harness fixing part 51 can be movably installed on the boss 4, and its side wall connection portion 56 can be movably installed in the bus space 3, that is, the wire harness fixing part 51 can be conveniently and flexibly installed in the wire harness channel 18, so as to facilitate the positioning, replacement and maintenance of the wire harness, and at the same time facilitate the replacement of the wire harness fixing part 51 to match wire harnesses of different specifications.

[0066] from Figure 6 It can also be seen from the embodiment that the first side wall 34 is provided with a terminal introduction port 33 at each bus space 3, and the terminal introduction port 33 is used to introduce the wiring harness terminal of the wiring harness located in the wiring harness space 2 into the bus space 3 to connect the battery pack through the bus therein.

[0067] according to Figure 6 In the embodiment, the busbar space 3 includes two second side walls 35 arranged opposite to each other and a third side wall 37 arranged opposite to the first side wall 34. The first side wall 34, the second side wall 35, the third side wall 37 and the bottom wall 14 form the busbar space 3. The top surface of the busbar space 3 is open to facilitate the installation of the busbar into the busbar space 3 from the top surface.

[0068] Specifically, bus bar connection ports 31 are provided near both ends of the bottom wall 14 of the bus bar space 3 , and the battery module can be connected to the bus bar through the bus bar connection ports 31 .

[0069] The third side wall 37 may also be provided with a mounting hole, which is used to clamp and fix the bus. The two opposite second side walls 35 are provided with a clamping limit device 32. As shown in the figure, the clamping limit device 32 is an elastic clamp, so that the bus can be easily installed or removed from the bus space through the elastic clamp.

[0070] according to Figure 6 In the embodiment, the busbar space 3 near the harness space 2 may also be provided with a limit plate 36, the limit plate 36 obliquely connected to the first side wall 34 and the second side wall 35 to conform to the shape of the busbar, thereby limiting the busbar and having a foolproof effect, ensuring the installation direction of the busbar to limit the movement of the busbar. Moreover, the limit plate 36 is connected to the two adjacent first side walls 34 and the second side wall 35, and can also reinforce the structure of the busbar space 3.

[0071] exist Figure 6 In the embodiment, the third side wall 37 close to the edge side wall 13 can be set to a trapezoidal shape, which protrudes inward from the bus space 3. The trapezoidal shape can keep the bus 6 away from the edge side wall 13 to increase the creepage distance, thereby ensuring electrical safety, and the trapezoidal structure can also increase the strength of the edge side wall 13, making it more secure.

[0072] Furthermore, it can be seen from the figure that there is a second gap 39 between two adjacent busbar spaces 3. The second gap 39 can keep a distance between the busbars to increase the electrical clearance and creepage distance between the busbars, thereby increasing the insulation performance between the busbars.

[0073] Figure 7 A schematic diagram of a supporting bracket of an embodiment of a wire harness isolation plate of the present invention.
