At the same time, the material of the cascading harness is relatively hard, and it is easy to damage the cascading harness when forced to press and install.

[0055] Based on this, an embodiment of the present application provides a battery pack, including: a battery pack, a sealing cover, a battery management module, at least one wiring structure and at least one connecting wire harness.

When assembling the sealing cover, the wiring structure is extended through the avoidance hole, thereby driving each connecting wire harness to extend through the avoidance hole, thereby facilitating the electrical connection between the connecting wire harness and the battery management module. By setting the wiring structure to limit the connecting wire harness, when the sealing cover is assembled by machine, it is convenient to lead the connecting wire harness out through the avoidance hole, and at the same time avoid the interference between the connecting wire harness and the surrounding side of the avoidance hole, thereby facilitating the assembly of the sealing cover by machine, and improving the efficiency of assembling the sealing cover. In addition, compared with manual assembly, the assembly efficiency is higher when the sealing cover is assembled by machine.

[0056] The embodiments of the present application are described below with reference to the accompanying drawings.

[0057] Reference Figure 1 , Figure 2 and Figure 3 The battery pack provided in the embodiment of the present application includes: a battery pack 100, a sealing cover 200, a battery management module 300, at least one wiring structure 400 and at least one connecting harness 500.

[0058] The connecting harness 500 electrically connects the battery pack 100 and the battery management module 300, the sealing cover 200 is covered on the battery pack 100, the wire management structure 400 is arranged on the battery pack 100, the wire management structure 400 is used to limit the connecting harness 500, the sealing cover 200 has an avoidance hole 210, the avoidance hole 210 is used to avoid the wire management structure 400, and the battery management module 300 is arranged on the side of the sealing cover 200 away from the battery pack 100.

[0059] Exemplarily, the battery pack further includes a battery tray 600, the battery tray 600 has a mounting groove, the battery pack 100 is located in the mounting groove, the sealing cover 200 is located above the battery pack 100, covers the opening of the mounting groove, and is connected to the peripheral side of the battery tray 600. The wire management structure 400 is disposed above the battery pack 100.

[0060] When the sealing cover 200 is assembled by a machine, that is, the sealing cover 200 is dropped from the top of the battery pack 100 onto the battery tray 600, the connecting harness 500 is limited on the wire management structure 400, and the avoidance hole 210 corresponds to the wire management structure 400, so that the wire management structure 400 can avoid interference with the surrounding side of the avoidance hole 210, thereby ensuring smooth assembly of the sealing cover 200.

[0061] Specifically, when assembling the battery pack, first electrically connect one end of the connection wire harness 500 to the battery pack 100, then connect the wire management structure 400 to the battery pack 100, and fixedly accommodate the connection wire harness 500 on the wire management structure 400 to limit the connection wire harness 500 through the wire management structure 400. Then, cover the sealing cover 200 on the battery pack 100 through a machine, and make the wire management structure 400 extend out through the avoidance hole 210 to lead out the connection wire harness 500 through the avoidance hole 210. Finally, install the battery management module 300 on the sealing cover 200 and electrically connect the other end of the connection wire harness 500 to the battery management module 300.

[0062] It can be understood that the shape and size of the avoidance hole 210 can match the wire management structure 400 and a part of the connection wire harness 500 between the battery pack 100 and the wire management structure 400.

[0063] For the battery provided in the embodiment of the present application, a wire management structure 400 is provided on the battery pack 100 to limit the connection wire harness 500 through the wire management structure 400. The sealing cover 200 has an avoidance hole 210. When assembling the sealing cover 200, the wire management structure 400 is made to extend out through the avoidance hole 210, thereby driving each connection wire harness 500 to extend out through the avoidance hole 210, so as to facilitate the electrical connection between the connection wire harness 500 and the battery management module 300. By providing the wire management structure 400 to limit the connection wire harness 500, when the machine assembles the sealing cover 200, it is convenient for the connection wire harness 500 to be led out through the avoidance hole 210, and at the same time, it is possible to avoid interference between the connection wire harness 500 and the periphery of the avoidance hole 210, thereby facilitating the machine to assemble the sealing cover 200 and improving the efficiency of assembling the sealing cover 200. In addition, compared with manual assembly, assembling the sealing cover 200 through a machine has a higher assembly efficiency.

[0064] Refer to Figure 4 and Figure 5 In some embodiments, the wire management structure 400 includes a base 410 and at least one mounting member 420. The mounting member 420 is rotatably connected to the base 410, and the base 410 is connected to the battery pack 100. The mounting member 420 can rotate relative to the base 410 to a first position or a second position. In the first position, the mounting member 420 fits against the base 410, and at least part of the connection wire harness 500 is located between the mounting member 420 and the base 410. In the second position, an opening is formed between the mounting member 420 and the base 410.

[0065] Specifically, the initial position of the mounting member 420 is the second position. First, place the connection wire harness 500 at the opening between the mounting member 420 and the base 410. Then, rotate the mounting member 420 relative to the base 410 to rotate the mounting member 420 to the first position, thereby limiting the connection wire harness 500 between the mounting member 420 and the base 410.

[0066] In this way, the mounting member 420 is rotatably connected to the base 410, so that the mounting member 420 can be rotated relative to the base 410 to the first position or the second position, thereby facilitating the limiting of the connection wire harness 500 between the mounting member 420 and the base 410.

[0067] Referring to Figure 4 、 Figure 5 and Figure 6 In specific implementation, the mounting member 420 has at least one first receiving groove 421. When in the first position, the first receiving groove 421 and the base 410 jointly define a first limiting hole 422, and the connection wire harness 500 is inserted into the first limiting hole 422.

[0068] Among them, the connection wire harness 500 is limited by the first limiting hole 422.

[0069] The first limiting hole 422 is a through hole, so that both ends of the connection wire harness 500 can extend out through both ends of the first limiting hole 422, thereby facilitating the electrical connection of the connection wire harness 500 with the battery pack 100 and the battery management module 300.

[0070] Referring to Figure 4 and Figure 5 In specific implementation, the mounting member 420 includes a cover plate 423 and at least one partition plate 424. The cover plate 423 is rotatably connected to the base 410, and the partition plate 424 is connected to the side of the cover plate 423 facing the base 410. The cover plate 423 and the partition plate 424 jointly define the first receiving groove 421.

[0071] Among them, one side of the cover plate 423 is rotatably connected to the base 410. The cover plate 423 can be arc-shaped or other shapes, as long as the cover plate 423 has a groove. The partition plate 424 is connected to the cover plate 423 to divide the groove into at least one first receiving groove 421. When in the first position, the other side of the cover plate 423 abuts against the base 410, so that the cover plate 423, the partition plate 424 and the base 410 jointly define the first limiting hole 422.

[0072] Referring to Figure 5 In specific implementation, the mounting member 420 further includes two side plates 425. The two side plates 425 are respectively connected to both sides of the cover plate 423 and are connected to both sides of the partition plate 424. The cover plate 423, the partition plate 424 and the side plates 425 jointly define a second receiving groove 426, and the second receiving groove 426 is used to accommodate the plug of the connection wire harness 500.

[0073] Exemplarily, the number of the partition plates 424 can be at least two, and the partition plates 424 are parallel to each other. The cover plate 423, the two partition plates 424 and the two side plates 425 jointly define a second receiving groove 426. Alternatively, the cover plate 423, the partition plates 424 and the two side plates 425 jointly define the second receiving groove 426.

[0074] The shape and size of the second receiving groove 426 can match the shape and size of the connector plug of the connection wire harness 500. The number of the second receiving grooves 426 can be at least two, and the shapes and sizes of the second receiving grooves 426 can be different or the same.

[0075] In a specific implementation, one end of the connection wire harness 500 is electrically connected to the battery pack 100. The connector plug of the connection wire harness 500 is located at the other end of the connection wire harness 500, and the connector plug of the connection wire harness 500 is used for electrically connecting to the battery management module 300.

[0076] In the second position, the connector plug of the connection wire harness 500 is inserted into the second receiving groove 426 to limit the connector plug of the connection wire harness 500 in the second receiving groove 426. Further, when the machine assembles the sealing cover 200 on the battery pack 100, the connector plug of the connection wire harness 500 will not interfere with the sealing cover 200, avoiding affecting the assembly of the sealing cover 200 by the machine. After assembling the sealing cover 200, the connector plug of the connection wire harness 500 is taken out from the second receiving groove 426 and electrically connected to the battery management module 300.

[0077] Refer to Figure 4 、 Figure 5 and Figure 9 Referring to

[0078] In some embodiments, the wire management structure 400 further includes at least one connecting rod 430. There are two limiting grooves 411 on the base 410. The connecting rod 430 is inserted on the mounting member 420, and both ends of the connecting rod 430 are respectively inserted into the limiting grooves 411, so that the mounting member 420 can rotate relative to the base 410.

[0079] Specifically, the connecting rod 430 can rotate relative to the limiting groove 411 to drive the mounting member 420 to rotate relative to the base 410. Alternatively, the mounting member 420 rotates relative to the connecting rod 430, so that the mounting member 420 rotates relative to the base 410.

[0080] Further, the number of the mounting members 420 can be at least two. The connecting rod 430 is inserted on each mounting member 420 at the same time. The connecting rod 430 rotates relative to the base 410 to drive each mounting member 420 to rotate synchronously relative to the base 410.

[0081] In some examples, the base 410 includes a base body and a baffle, and the baffle is disposed around the periphery of the base body. The mounting member 420 is located above the base body, and the limiting groove 411 is located on the baffle.

[0082] In a specific implementation, the limiting groove 411 is a strip-shaped groove, and the connecting rod 430 moves along the limiting groove 411 to drive the mounting member 420 to move on the base 410 .

[0083] The connecting rod 430 moves along the limiting groove 411 relative to the base 410 to drive the mounting member 420 to move relative to the base 410 , thereby adjusting the relative position of the mounting member 420 on the base 410 .

[0084] Specifically, in the second position, there is an opening between the mounting member 420 and the base 410. At this time, the positive projection of the mounting member 420 on the base 410 needs to be located inside the base 410 to avoid interference between the mounting member 420 and the surrounding side of the avoidance hole 210 when the sealing cover 200 is installed on the battery pack 100, thereby avoiding affecting the installation of the sealing cover 200.

[0085] The extension direction of the connecting rod 430 is the same as the extension direction of the first limiting hole 422, the extension direction of the limiting groove 411 is perpendicular to the extension direction of the connecting rod 430, and the extension direction of the limiting groove 411 is horizontal, so that the connecting rod 430 drives the mounting member 420 to move in the horizontal direction, thereby adjusting the position of the orthographic projection of the mounting member 420 on the base 410, ensuring that the orthographic projection of the mounting member 420 on the base 410 is located inside the base 410.

[0086] Reference Figure 6 In a specific implementation, the base 410 also has at least one limiting member 412 . When in the second position, the mounting member 420 abuts against the limiting member 412 so that the positive projection of the mounting member 420 on the base 410 is located inside the base 410 .

[0087] Among them, the limiting member 412 is located on the side of the mounting member 420 away from the opening of the mounting member 420 and the base 410, and the mounting member 420 abuts against the limiting member 412 to limit the angle between the mounting member 420 and the base 410, thereby preventing the direct projection of the mounting member 420 on the base 410 from being located outside the base 410.

[0088] Exemplarily, the limiting member 412 is a limiting plate or a limiting protrusion.

[0089] In a specific implementation, the wire management structure 400 further includes at least one fixing member, which is disposed on the base 410 and is used to fix the connecting wire harness 500 .

[0090] Among them, by providing a fixing member, the connecting wire harness 500 is fixed to the wire management structure 400, preventing the connecting wire harness 500 from warping and affecting subsequent assembly.

[0091] Exemplarily, the connecting wire harness 500 can be first fixed to the fixing member and then fixed between the mounting member 420 and the base 410.

[0092] In some embodiments, at least one fixing member is provided on the sealing cover 200. The fixing member is used to fix the connecting wire harness 500 between the wire management structure 400 and the battery management module 300, preventing the connecting wire harness 500 between the wire management structure 400 and the battery management module 300 from warping.

[0093] Refer to Figure 5 and, in specific implementation, the fixing member includes at least one of a cable tie 440 and a clamping member 450.

[0094] Among them, the fixing member includes at least one cable tie 440 and / or at least one clamping member 450.

[0095] Refer to Figure 8 and Figure 9 and, specifically, the cable tie 440 includes a strip 441, a fixing sleeve 442, and a first fixing portion 444. One end of the strip 441 is fixedly connected to the outer surface of the fixing sleeve 442. The strip 441 surrounds the circumferential side of the connecting wire harness 500, and the other end of the strip 441 is inserted into the fixing sleeve 442 to fix the connecting wire harness 500 between the strip 441 and the fixing sleeve 442. The strip 441 is a toothed strip, and a fastening portion is provided in the fixing sleeve 442 for fixing the strip 441. By adjusting the fixing position of the strip 441 and the fastening portion, the length of the strip 441 on the circumferential side of the connecting wire harness 500 is further adjusted, so that the strip 441 fixes or releases the fixing of the connecting wire harness 500.

[0096] The first fixing part 444 includes a connecting plate 445 and two springs 446. The connecting plate 445 is connected to the fixing sleeve 442. One end of the spring 446 is connected to the side of the connecting plate 445 away from the fixing sleeve 442, and the two springs 446 are arranged opposite to each other. The base 410 has a first fixing plate 414, and the first fixing plate 414 has a first fixing hole 415. The first fixing part 444 is inserted into the first fixing hole 415 so that the spring 446 and the fixing sleeve 442 are respectively located on both sides of the first fixing plate 414, and then the connecting plate 445 can be limited in the first fixing hole 415 by the two springs 446, so that the cable tie 440 is fixed to the base 410. The cable tie 440 also includes two supporting plates 447, which are respectively connected to both sides of the fixing sleeve 442 and abut against the first fixing plate 414. At least one first reinforcing plate is connected to one side of the first fixing plate 414 . The first reinforcing plate is used to support the first fixing plate 414 . The first reinforcing plate is located on a side of the first fixing plate 414 facing away from the supporting plate 447 .

[0097] Reference Figure 8 and Figure 10 Specifically, the clamping member 450 includes a second fixing portion 451 and a buckle 453. The fixing portion 451 has a slot 452. The buckle 453 is elastically connected to the second fixing portion 451 and is at least partially located in the slot 452. In a specific implementation, the connecting wire harness 500 is inserted into the slot 452, and the buckle 453 abuts against the connecting wire harness 500 to fix the connecting wire harness 500 in the slot 452.

[0098] In some embodiments, the base 410 has a second fixing plate 416, and the second fixing plate 416 has a second fixing hole 417. The second fixing plate 416 is located on one side of the second fixing member 450, and the connecting harness 500 is fixed in the slot 452 through the second fixing hole 417. Further, the second fixing hole 417 can be a round hole. At least one second reinforcing plate is connected to one side of the second fixing plate 416, and the second reinforcing plate is used to support the second fixing plate 416.

[0099] In some examples, the number of the mounting members 420 is at least two, the mounting members 420 are arranged at intervals, and the fixing member is located between two adjacent mounting members 420 .

[0100] Further, the number of the mounting members 420 can be two, the two mounting members 420 are parallel, the connecting rod 430 is inserted into the two mounting members 420 at the same time, and the connecting rod 430 moves along the limiting groove 411 to drive the two connecting rods 430 to move synchronously relative to the base 410. The fixing member includes a cable tie 440 and a clamping member 450, and the cable tie 440 and the clamping member 450 are both located between the two mounting members 420.

[0101] Reference Figure 8 ,Figure 11 and Figure 12 In some embodiments, the cable tie 440 defines a second limiting hole 443, and the connecting wire harness 500 is sequentially located in the second limiting hole 443 and between the mounting member 420 and the base 410.

[0102] Among them, by providing the cable tie 440, the connecting wire harness 500 between the mounting member 420 and the base 410 is further fixed, preventing the connecting wire harness 500 from coming out between the mounting member 420 and the base 410.

[0103] Specifically, both ends of the strip 441 are connected to the fixing sleeve 442. The strip 441 is bent to define the second limiting hole 443. By adjusting the fixing position of the strip 441 in the fixing sleeve 442, the size of the second limiting hole 443 can be adjusted.

[0104] It can be understood that part of the connecting wire harness 500 is located in the first limiting hole 422, and at the same time part of the connecting wire harness 500 is located in the second limiting hole 443. The extending direction of the first limiting hole 422 is the same as that of the second limiting hole 443, so as to facilitate arranging the connecting wire harness 500 in the first limiting hole 422 and the second limiting hole 443 in sequence.

[0105] In some embodiments, the position of at least one of the mounting member 420 and the cable tie 440 on the base 410 is adjustable to adjust the length of part of the connecting wire harness 500 between the mounting member 420 and the cable tie 440.

[0106] Among them, by adjusting the distance between the mounting member 420 and the cable tie 440, the distance between the first limiting hole 422 and the second limiting hole 443 can be adjusted. Furthermore, the length of the connecting wire harness 500 between the first limiting hole 422 and the second limiting hole 443 can be adjusted. At the same time, the routing of the connecting wire harness 500 can be changed, preventing the relatively long connecting wire harness 500 from redundantly piling up on the wire management structure 400, and improving the applicability of the wire management structure 400.

[0107] Exemplarily, the position of the mounting member 420 on the base 410 is adjustable. Specifically, by adjusting the position of the connecting rod 430 in the limiting groove 411, the position of the mounting member 420 on the base 410 can be adjusted.

[0108] Specifically, referring to Figure 11 and Figure 12 , the cable tie 440 is located between two adjacent mounting members 420. By synchronously moving the two mounting members 420 relative to the base 410, the connecting wire harness 500 between the two mounting members 420 is changed from a straight shape to a bent shape, thereby increasing the length of the connecting wire harness 500 that can be arranged between the two mounting members 420, and increasing the length range of the connecting wire harness 500 that can be arranged between the two mounting members 420.

[0109] Referring to Figure 8 , in specific implementation, the base 410 also has a mating portion 413, and the mating portion 413 is used to cooperate with the honeycomb board of the battery pack.

[0110] Among them, by setting the mating portion 413, the mating portion 413 matches at least part of the honeycomb board to play a positioning role for the honeycomb board. Exemplarily, the mating portion 413 includes a plurality of positioning holes, and the positioning holes are strip-shaped holes.

[0111] The honeycomb board has high strength and high rigidity, can withstand large mechanical stresses and impact forces, and protects the battery cells and other components inside the battery pack. The honeycomb structure helps air circulation, improves heat dissipation performance, helps the battery pack dissipate heat more effectively, extends battery life and improves safety. The honeycomb board has good shock absorption and energy absorption performance, can absorb and disperse external impact forces, and protects the battery cells from vibration and impact damage.

[0112] Referring to Figure 3 and Figure 7 , in specific implementation, the wire management structure 400 further includes a connecting member 460, and the connecting member 460 connects the base 410 and the battery pack 100.

[0113] Among them, the connection manner of the connecting member 460 with the base 410 and the battery pack 100 can be snap connection, threaded connection, bonding or pin connection, etc.

[0114] Specifically, the battery pack 100 includes a plurality of single batteries arranged in sequence, and the base 410 is connected to at least one single battery through the connecting member 460.

[0115] In some embodiments, the connecting member 460 is an adhesive.

[0116] Among them, the adhesive is located on the surface of the base 410 facing away from the mounting member 420. Bonding the base 410 and the battery pack 100 through the adhesive is relatively simple and convenient, and the adhesive only bonds to the battery pack 100, with less impact on the battery pack 100.

[0117] Specifically, the adhesive is bonded to the top surface of at least one single battery. The number of adhesives can be multiple, and the adhesives are arranged at intervals in sequence, and the adhesives are correspondingly bonded to the top surface of the single battery.

[0118] It can be understood that the larger the bonding area of the adhesive with the base 410 and the single battery, the firmer the bonding of the adhesive with the base 410 and the single battery.

[0119] Exemplarily, the bonding member is a foam adhesive. The foam adhesive has a relatively strong adhesive force, can firmly bond the base 410 and the battery pack 100, and is relatively convenient to use. The protective layer can be torn off for bonding. At the same time, the foam adhesive is relatively light in weight and has little impact on the weight of the battery pack. In addition, the foam adhesive also has good shock absorption and buffering performance, and can effectively absorb impacts and vibrations.

[0120] In some embodiments, the battery pack provided by the embodiments of the present application further includes a box cover, which is covered on the battery management module 300 and the wire management structure 400, and is connected to the sealing cover 200. There is a preset distance between the wire management structure 400 and the inner wall of the sealing cover 200.

[0121] Wherein, by providing the box cover, the periphery of the avoidance hole 210 is sealed. By providing the preset distance, it is avoided that when the box cover is covered on the wire management structure 400, the box cover interferes with the wire management structure 400 and affects the connection between the box cover and the sealing cover 200.

[0122] Exemplarily, the battery pack further includes a sealing gasket, which is hermetically connected to the box cover and the sealing cover 200.

[0123] Specifically, at the first position, there is a preset distance between the side of the mounting member 420 away from the base 410 and the inner wall of the sealing cover 200. The specific value of the preset distance can be adaptively set according to actual needs, and is not limited herein in this embodiment.

[0124] In specific implementation, first electrically connect one end of the connection wire harness 500 to the battery pack 100, then connect the wire management structure 400 to the battery pack 100, and sequentially fix the connection wire harnesses 500 on the wire management structure 400. At this time, the mounting member 420 is located at the second position. Then cover the sealing cover 200 on the battery pack 100, and make the wire management structure 400 extend out through the avoidance hole 210. After that, sequentially remove the connection wire harnesses 500 from the wire management structure 400 and electrically connect them to the battery management module 300. Finally, after rotating the mounting member 420 relative to the base 410 to the first position, cover the box cover on the wire management structure 400 and the battery management module 300 and seal it with the sealing cover 200.

[0125] Based on the above embodiments, the embodiments of the present application provide an electrical device, including a device body and a battery pack provided on the device body.

[0126] Wherein, the structure of the battery pack has been described in detail in the above embodiments, and will not be elaborated herein.

[0127] Exemplarily, the electrical device includes a vehicle.

[0128] The electrical device provided by the embodiment of the present application, the battery pack includes a wire management structure 400, and the connecting wire harness 500 is limited by the wire management structure 400. The sealing cover 200 has an avoidance hole 210. When assembling the sealing cover 200, the wire management structure 400 extends out through the avoidance hole 210, and then drives each connecting wire harness 500 to extend out through the avoidance hole 210, so as to facilitate the electrical connection between the connecting wire harness 500 and the battery management module 300. By setting the wire management structure 400 to limit the connecting wire harness 500, when the machine assembles the sealing cover 200, the connecting wire harness 500 can be led out through the avoidance hole 210, avoiding interference between the connecting wire harness 500 and the periphery of the avoidance hole 210, thus facilitating the machine to assemble the sealing cover 200 and improving the efficiency of assembling the sealing cover 200.
