DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0036] In the description of the present application, it should be understood that the terms "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot 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 one or more features. In the description of the present application, "multiple" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined.

[0037] In the related technology, the battery pack is composed of stacked battery cells. As a component for collecting the voltage / temperature of the battery cell in the battery pack, the CCS component usually needs to be cleverly designed and reasonably arranged, so that the voltage / temperature of each battery cell can be collected under limited space. In comparison, the CCS component of the wiring harness solution requires more space, and each collection line needs to be fixed separately, and the bus needs to be fixed as a whole. However, when multiple collection lines converge from different places, there is no better fixing method, resulting in large gaps between the multiple collection lines, bending and fluffy, thus occupying a larger space in the battery pack, which is not conducive to improving the energy density inside the battery pack.

[0038] In view of this, an embodiment of the present application provides a battery pack to solve the above-mentioned problem.

[0039] Please refer to Figure 1-Figure 3 , Fig. 9 The embodiment of the present application provides a battery pack, including a plurality of battery cells 2 and an integrated busbar 1, wherein the integrated busbar 1 is arranged on one side of the plurality of battery cells 2; the integrated busbar 1 includes an insulating plate 12, a plurality of collection lines 11, and a fixing member 13. The insulating plate 12 is arranged on one side of the plurality of battery cells 2, and a wire groove 121 is provided on a side of the insulating plate 12 away from the battery cells 2. The plurality of collection lines 11 are used to be electrically connected to the battery cells 2, and at least part of the collection lines 11 are arranged in the wire groove 121. The fixing member 13 is arranged across the wire groove 121 along the width direction X of the wire groove 121, and the fixing member 13 is connected to the insulating plate 12 to press at least part of the collection lines 11 into the wire groove 121.

[0040] In the embodiment of the present application, a wire groove 121 is provided on the insulating plate 12 to accommodate the plurality of collection wires 11, and a fixing member 13 is used to span the wire groove 121 and be fixed on both sides of the wire groove 121, so that the plurality of collection wires 11 are pressed into the wire groove 121, thereby realizing the arrangement and fixation of the plurality of wire harnesses when the wire harnesses are dense and of limited size, effectively reducing the gaps between the plurality of wire harnesses, reducing the space occupied, and especially reducing the size along the height direction of the battery cell 2, thereby avoiding affecting the overall height size of the battery pack.

[0041] Specifically, the multiple battery cells 2 of the present application can be arranged in sequence along the length direction Y of the wire slot 121, and the integrated busbar 1 is arranged on the pole side of the multiple battery cells 2. The integrated busbar 1 may include an insulating plate 12, multiple aluminum bars, and multiple collection lines 11. The insulating plate 12 is arranged on the pole side of the multiple battery cells 2, and multiple openings corresponding to the poles are arranged on the insulating plate 12. Multiple aluminum bars are arranged at the openings one by one and are conductively connected to the poles of the battery cells 2. At the same time, multiple collection lines 11 are connected to multiple aluminum bars one by one to collect voltage and temperature information of the battery cells 2. Since the collection line 11 needs to be arranged and routed according to demand, the collection line 11 can usually be arranged on the side of the insulating plate 12 away from the battery cell 2, so as to facilitate the arrangement of the collection line 11. Therefore, the wire slot 121 in the embodiment of the present application is preferably arranged on the side of the insulating plate 12 away from the battery cell 2, thereby reducing the gap between the insulating plate 12 and the single battery, thereby reducing the impact on the size of the battery pack.

[0042] The wire groove 121 is arranged on the side of the insulating plate 12 away from the battery cell 2. At this time, the multiple collection lines 11 are led out from the aluminum bar and arranged in the wire groove 121, and then the fixing piece 13 is used to cross the wire groove 121 along the width direction X of the wire groove 121 and fixed on both sides of the wire groove 121, so as to realize the compression and fixation of the multiple collection lines 11, thereby effectively reducing the gaps between the multiple collection lines 11 and the space occupied by the multiple collection lines 11, avoiding the problem of the difficulty in arranging the wire harness caused by the multiple collection lines 11 jumping out of the wire groove 121 and the problem of occupying more space, and ensuring that the collection lines 11 of the integrated busbar 1 are neatly routed.

[0043] It should be noted that the fixing member 13 is arranged across the wire groove 121 along the width direction X of the wire groove 121, which can be understood as spanning from one side of the wire groove 121 to the other side of the wire groove 121 along the width direction X of the wire groove 121, so that the fixing member 13 covers the wire groove 121 along the width direction X of the wire groove 121, and at the same time, both ends of the fixing member 13 are partially connected to the insulating plate 12 on both sides of the wire groove 121 to fix the fixing member 13. At the same time, the fixing member 13 is pressed onto the wire groove 121 along the width direction X, which can ensure that the collection line 11 is completely pressed into the wire groove 121, thereby ensuring the fixing effect of the collection line 11 and reducing the influence of the collection line 11 on the height size of the battery pack.

[0044] Please refer to Figure 6-Figure 9 In some embodiments, the fixing member 13 includes a main body 131 and at least two fixing buckles 132 connected to the main body 131, the main body 131 is arranged across the wire groove 121 along the width direction X, and at least two fixing buckles 132 are arranged on both sides of the wire groove 121 along the width direction X and are detachably connected to the insulating plate 12.

[0045] In the embodiment of the present application, the fixing member 13 uses the main body 131 to span across the wire slot 121 for pressing and installing multiple collection lines 11, and is detachably connected to the insulating plate 12 using the fixing buckle 132. At this time, the height of the fixing buckle 132 can be designed according to needs to achieve press-fit fixation of different numbers of collection lines 11.

[0046] At the same time, in the embodiment of the present application, the fixing buckle 132 is detachably connected to the insulating plate 12, which can facilitate the fixing of the wires after wiring, facilitate the wiring arrangement of the collection wires 11, and reduce the difficulty of wiring and routing the collection wires 11.

[0047] Please refer to Figure 3-Figure 5 , Fig. 9 In some embodiments, the insulating plate 12 is provided with at least two fixing holes 122 , and the at least two fixing holes 122 are relatively arranged on both sides of the wire groove 121 along the width direction X, and the fixing buckle 132 is detachably arranged on the fixing hole 122 .

[0048] In the embodiment of the present application, the insulating plate 12 is provided with at least two fixing holes 122 relatively arranged on both sides of the wire groove 121 along the width direction X, and the fixing buckle 132 of the fixing member 13 is detachably fixed in the fixing hole 122, thereby achieving the fixing of the fixing member 13. This fixing method can reduce the overall material cost of the insulating plate 12, and reduce the difficulty of manufacturing the insulating plate 12 and the weight of the insulating plate 12, which is convenient for improving the energy density of the battery pack.

[0049] Preferably, the fixing hole 122 may be a long hole extending along the length direction Y of the wire groove 121 , which can facilitate flexible adjustment of the fixing position of the fixing member 13 and improve the flexibility of fixing the fixing member 13 .

[0050] It should be noted that the fixing hole 122 of the present application may not penetrate the insulating plate 12. In this case, the fixing hole 122 may be a hole sunk in the insulating plate 12, and the thickness of the corresponding insulating plate 12 needs to be set thicker; or, a protrusion may be set on the insulating plate 12, and the fixing hole 122 is set in the protrusion, so that the fixing hole 122 and the fixing buckle 132 can be fixed. Of course, the fixing hole 122 may penetrate the insulating plate 12, and the fixing buckle 132 may be clamped in the fixing hole 122, or may be penetrated in the fixing hole 122 and protrude on the side of the insulating plate 12 facing the battery cell 2, and the fixing buckle 132 is limited and positioned by the insulating plate 12 to prevent the fixing member 13 from falling off and maintain the stability of the fixing of the fixing member 13.

[0051] It should also be noted that one fixing member 13 preferably includes two fixing buckles 132, which are used to be fixed on both sides of the wire slot 121 when the body 131 is straddled on the wire slot 121. Therefore, there are also two fixing holes 122 that match one fixing member 13, so as to achieve one-to-one fixation of the fixing holes 122. In the embodiment of the present application, at least two fixing holes 122 are set on both sides of the wire slot 121, and multiple pairs of fixing holes 122 can be set on both sides of the wire slot 121 in a one-to-one correspondence, so as to flexibly adjust the fixed position of the fixing member 13, and can also be used to fix multiple fixing members 13, so as to achieve better organization and fixation of multiple collection lines 11.

[0052] Please refer to Figure 6 and Figure 8 In some embodiments, the fixing member 13 includes at least one first reinforcing portion 133 , the first reinforcing portion 133 is connected to a side of the body 131 facing away from the line slot 121 , and the first reinforcing portion 133 extends along the width direction X.

[0053] In the embodiment of the present application, a first reinforcing portion 133 is provided and connected to a side of the main body 131 facing away from the wire slot 121, mainly used to improve the strength of the main body 131, to avoid deformation of the main body 131 caused by a larger wire diameter after the plurality of collection wires 11 are merged when there are many collection wires 11 and the fixing buckles 132 at both ends of the main body 131 are pressed down and fixed in the fixing holes 122, and to avoid excessive bending or even breakage of the main body 131 in a direction away from the wire slot 121.

[0054] like Figure 7 As shown, in some embodiments, the fixing member 13 includes at least one second reinforcing portion 134 , which is disposed on a side of the body 131 facing the wire groove 121 , and the second reinforcing portion 134 is connected to both the body 131 and the fixing buckle 132 .

[0055] In the embodiment of the present application, a second reinforcing portion 134 is provided to increase the connection strength between the main body 131 and the fixing member 13 to prevent the main body 131 from being broken at the connection between the main body 131 and the fixing buckle 132 when the main body 131 is supported and deformed by multiple collection lines 11, thereby ensuring the structural stability of the fixing member 13.

[0056] In the embodiment of the present application, the fixing buckle 132 is bent relative to the body 131, so that the body 131 can be pressed onto the wire slot 121 along the width direction X, and the fixing buckle 132 is inserted into and fixed to the fixing hole 122 on the insulating plate 12. The body 131 and the fixing buckle 132 can be bent at 90 degrees. In this case, a second reinforcing portion 134 is provided on a side of the fixing buckle 132 close to the body 131, and the second reinforcing portion 134 is connected to the body 131 and the fixing buckle 132 respectively, so that the connection strength between the body 131 and the fixing buckle 132 can be effectively guaranteed.

[0057] Please refer to Figure 6-Figure 8 In some embodiments, the fixing member 13 further includes at least one extension portion 135 , and the extension portion 135 is connected to the body 131 along the length direction Y of the wire groove 121 .

[0058] In the embodiment of the present application, an extension portion 135 is further provided on the side of the main body 131. There may be only one extension portion 135, or extension portions 135 may be provided on both sides of the main body 131. By providing the extension portion 135, the pressing area of ​​the fixing member 13 for multiple collection lines 11 can be increased, thereby ensuring the fixing effect of the fixing member 13 on the collection lines 11, and further ensuring the neat arrangement of the collection lines 11 in the wire groove 121.

[0059] Please refer to Figure 4 , Figure 5 and Fig. 9 In some embodiments, a limiting member 123 is provided in the fixing hole 122 , and the limiting member 123 is connected to the hole wall 1221 of the fixing hole 122 . The limiting member 123 cooperates with the fixing buckle 132 to limit the fixing member 13 and connect the insulating plate 12 .

[0060] In the embodiment of the present application, by setting the position-limiting member 123, the position-limiting member 123 can be used to cooperate with the fixing buckle 132 to limit the position, so that the fixing buckle 132 is fixed in the fixing hole 122, and the connection between the fixing member 13 and the insulating plate 12 is realized. The present application uses the position-limiting member 123 to limit the fixing buckle 132, which is not only convenient for fixing the fixing buckle 132, but also convenient for disassembly of the fixing buckle 132.

[0061] It should be noted that the fixing buckle 132 and the limiting member 123 limit each other. Specifically, the fixing buckle 132 can be passed through the fixing hole 122 and partially arranged on the side of the limiting member 123 facing the battery cell 2, so as to achieve mutual limitation in the height direction, thereby preventing the fixing buckle 132 from loosening from the fixing hole 122.

[0062] It should also be noted that in the embodiment of the present application, the aperture of the fixing hole 122 can be set larger, so as to reduce the material usage of the insulating plate 12, and only the limiting member 123 is set to protrude from the hole wall 1221 of the fixing hole 122 to achieve the limiting of the fixing buckle 132. At the same time, the fixing buckle 132 of the present application is an elastic member, which can be squeezed and deformed and reset along the width direction X. Therefore, when the fixing member 13 is installed, it is only necessary to squeeze the fixing buckle 132 toward each other along the width direction X, so that the two fixing buckles 132 are deformed toward each other and inserted into the fixing hole 122, and the fixing buckle 132 can be released until the fixing buckle 132 reaches below the limiting member 123 and can be limited by the limiting member 123, and then the fixing member 13 can be fixed on the insulating plate 12. When the fixing buckle 132 needs to be removed, it is only necessary to squeeze the fixing buckle 132 toward each other again, so that the fixing buckle 132 is separated from the limiting member 123, and the fixing member 13 can be removed.

[0063] Please refer to Figure 4 and Figure 5 In some embodiments, the limiting member 123 includes a plate body 1231 and at least one third reinforcing portion 1232, the plate body 1231 is connected to the hole wall 1221 of the fixing hole 122, and the third reinforcing portion 1232 is respectively connected to the plate body 1231 and the hole wall 1221 of the fixing hole 122; the fixing buckle 132 includes an extension arm 1321 and a buckle body 1322, the extension arm 1321 is arranged between the main body 131 and the buckle body 1322, and is respectively connected to the main body 131 and the buckle body 1322; when the fixing member 13 is connected to the insulating plate 12, along the direction of the battery cell 2 toward the insulating plate 12, at least a portion of the plate body 1231 is arranged opposite to the buckle body 1322, so that the plate body 1231 and the buckle body 1322 cooperate to limit.

[0064] In the embodiment of the present application, the plate body 1231 is used to limit the fixing buckle 132, and the third reinforcing portion 1232 is used to increase the connection strength between the plate body 1231 and the hole wall 1221. At this time, even if the plate body 1231 is relatively thin, the third reinforcing portion 1232 can support the plate body 1231, which can also play a role in limiting and fixing the fixing buckle 132. The extension arm 1321 of the fixing buckle 132 has a certain deformation ability, which is used to squeeze and deform toward each other and send the buckle body 1322 to the bottom of the plate body 1231 or to escape from the bottom of the plate body 1231 when the fixing member 13 is disassembled. Among them, the buckle body 1322 is used to achieve cooperation and limitation with the plate body 1231, thereby achieving the fixation of the fixing member 13. Since the fixing member 13 is pressed down in the height direction to be installed on the wire slot 121 and fixed on both sides of the wire slot 121, it is preferred to use the plate body 1231 and the buckle body 1322 to limit each other in the height direction, which is convenient for fixing and disassembly of the fixing member 13.

[0065] like Figure 4As shown, in some embodiments, the wire groove 121 has a bottom wall 1211 and a side wall 1212, the side wall 1212 is connected to the bottom wall 1211 to form the wire groove 121, and a first limiting groove 12121 is provided on the side of the side wall 1212 away from the bottom wall 1211, and the first limiting groove 12121 is used to accommodate the main body 131; the side wall 1212 is also provided with a second limiting groove 12122, and the second limiting groove 12122 is connected to the first limiting groove 12121, and is used to accommodate the second reinforcement portion 134.

[0066] In the embodiment of the present application, the first limiting groove 12121 is provided to limit the position of the fixing member 13 along the length direction Y, thereby ensuring the accuracy of the fixing position. The second limiting groove 12122 is provided to accommodate the second reinforcing portion 134, thereby avoiding position interference with the second reinforcing portion 134, and the second limiting groove 12122 can also limit the second reinforcing portion 134 along the length direction Y, thereby further limiting the extension direction Y of the fixing member 13.
