[0045] The embodiments of the present application are described below Figures 1-8 The embodiments of the present application are described below

[0046] According to the embodiments of the present application, in a first aspect, a battery pack 1 is provided, the battery pack 1 has a first direction Y and a second direction Z intersecting with each other, and the battery pack 1 comprises a box body 100, a cover plate 102, a battery pack 200, a partition plate 300 and a pressing strip 600.

[0047] The cover plate 102 is connected with the box body 100, and the cover plate 102 and the box body 100 form an accommodating cavity 101. The battery pack 200 located in the accommodating cavity 101 comprises a plurality of batteries 210, and the plurality of batteries 210 are arranged along the first direction Y, and the battery 210 comprises a top cover 212. The partition plate 300 is located in the accommodating cavity 101, and the partition plate 300 is arranged between the battery pack 200 and the cover plate 102 along the second direction Z, and a side of the partition plate 300 facing the battery pack 200 is provided with an accommodating groove 326. The partition plate 300 can be made of insulating material, for example, the partition plate 300 is made of insulating plastic, which can separate the battery pack 200 from the cover plate 102, avoid electrical connection between the battery pack 200 and the cover plate 102, prevent the cover plate 102 from being electrified, and improve the safety of the battery pack 1.

[0048] The pressing strip 600 is arranged in the accommodating cavity 101, and the pressing strip 600 extends along the first direction Y, and the pressing strip 600 is located between the battery pack 200 and the partition plate 300 along the second direction Z, the pressing strip 600 is connected with the top cover 212, and the pressing strip 600 is at least partially located in the accommodating groove 326 and connected with the partition plate 300.

[0049] By arranging the pressing strip 600 in the accommodating groove 326, the relative position between the pressing strip 600 and the partition plate 300 can be fixed, the pressing strip 600 and the top cover 212 can be bonded, and the top cover 212 of each of the plurality of batteries 210 in the battery pack 200 can be connected with the pressing strip 600, so that the pressing strip 600 can fix the relative position between the plurality of top covers 212, inhibit the expansion of the battery 210, thereby fixing the relative position between the partition plate 300 and the battery pack 200, ensuring the stability of the relative position between the battery 210 and the busbar 500 on the partition plate 300, and reducing the tearing force on the partition plate 300, thereby reducing the damage probability of the partition plate 300.

[0050] In addition, since the pressing strip 600 is arranged between the battery pack 200 and the partition plate 300, on the one hand, the connection between the pressing strip 600 and the battery pack 200 is more convenient, and on the other hand, the contact area between the pressing strip 600 and the battery pack 200 is large, which is conducive to improving the connection strength between the pressing strip 600 and the top cover 212 of the battery 210, and is conducive to improving the effect of the pressing strip 600 on inhibiting the expansion of the battery 210, thereby effectively fixing the relative position between the partition plate 300 and the battery pack 200.

[0051] like Figure 3 As shown, in the technical solution of this embodiment, the separator 300 is provided with a through hole 321 extending along the second direction Z, through which the top cover 212 and the pressure strip 600 protrude. In this way, adhesive can be injected between the pressure strip 600, the separator 300, and the top cover 212 of the battery 210 through the through hole 321, improving the connection strength between the pressure strip 600, the separator 300, and the top cover 212 of the battery 210, further enhancing the effect of the pressure strip 600 in suppressing the expansion of the battery 210, and reducing the probability of relative displacement between the separator 300 and the battery pack 200.

[0052] Specifically, the battery pack 1 also includes an adhesive component, which is at least disposed in the through hole 321 and connects the top cover 212, the pressure strip 600, and the separator 300. This adhesive component can improve the connection strength between the top cover 212, the pressure strip 600, and the separator 300, reduce the probability of damage to the separator 300, and further improve the modal characteristics of the battery pack. The adhesive component can be a foam adhesive.

[0053] like Figure 4 As shown, in the technical solution of this embodiment, the isolation plate 300 includes a body 360 and a pressing plate 330. The pressing plate 330 is connected to the body 360, and the receiving groove 326 is disposed on the body 360. At least a portion of the pressing plate 330 is projected along the second direction Z into the receiving groove 326.

[0054] The battery pack 1 also includes a flexible printed circuit (FPC) 400, a portion of which is located between the pressure strip 600 and the battery pack 200. The flexible printed circuit 400 includes a temperature sensing end 401, located within a through hole 321 and in contact with the top cover 212. A pressure plate 330 is pressed onto the side of the temperature sensing end 401 facing away from the top cover 212. An elastic element 350 can be clamped between the pressure plate 330 and the temperature sensing end 401 to ensure that the pressure plate 330 reliably presses the temperature sensing end 401. The temperature sensing end 401 is used to collect the temperature of the battery 210. By setting the pressure plate 330, a tight fit between the temperature sensing end 401 and the top cover 212 can be ensured, improving the connection reliability between the temperature sensing end 401 and the top cover 212, thereby increasing the reliability of temperature detection.

[0055] At least a portion of the flexible circuit board 400 is located between the pressure strip 600 and the battery pack 200, which enables the flexible circuit board 400 to be effectively pressed onto the battery pack 200, thereby improving the reliability of the fit between the flexible circuit board 400 and the battery pack 200.

[0056] In addition, along the second direction Z, the pressing piece 330 is closer to the cover plate 102 relative to the body 360. In this way, the maximum dimension between the groove wall of the accommodating groove 326 and the top cover 212 can be reduced, the arrangement space required by the isolation plate 300 is reduced, and the structure in the battery pack 1 is more compact.

[0057] As shown in Figure 7 River Figure 8 In the technical scheme of the embodiment, the battery pack 1 also has a third direction X intersecting the first direction Y and the second direction Z, the box body 100 includes a frame 105, a connecting beam 103 and a fastener 104, the frame 105 is connected with the cover plate 102 and encloses to form the accommodating cavity 101, and the connecting beam 103 is located in the accommodating cavity 101. The connecting beam 103 extends along the third direction X and connects the frame 105, and the fastener 104 penetrates the isolation plate 300 and the pressing strip 600 to fixedly connect the isolation plate 300 and the pressing strip 600 to the connecting beam 103. The fastener 104 can be a fixing structure such as a bolt.

[0058] By arranging the connecting beam 103, the structural strength of the box body 100 can be increased, and the structural strength of the battery pack 1 is further increased. The connecting beam 103, the pressing strip 600 and the isolation plate 300 are connected, the connecting strength between the isolation plate 300, the box body 100 and the pressing strip 600 is increased, and the relative positions of the box body 100, the isolation plate 300 and the pressing strip 600 are fixed.

[0059] As shown in Figure 3 And Figure 6 As shown in

[0060] In addition, the pressing strip 600 and the part of the top cover 212 exposed from the window 214 are connected. By arranging the insulating piece 213, the top cover 212 and the cover plate 102 can be separated, the insulation effect between the top cover 212 and the cover plate 102 is increased, the cover plate 102 is further prevented from being electrified, and the pressing strip 600 can contact the top cover 212 through the window 214 to ensure the connection effect between the battery 210 and the pressing strip 600, which is beneficial to fixing the relative positions of the plurality of batteries 210 through the pressing strip 600.

[0061] In some embodiments, at least one end of the window 214 extends beyond the pressure strip 600 in a third direction X, and the adhesive is at least partially inserted into the window 214 to connect the top cover 212, the pressure strip 600, and the partition plate 300. Thus, the top cover 212, the pressure strip 600, and the partition plate 300 can be firmly connected in one go by applying adhesive, and the connection area can be increased and the connection strength can be improved.

[0062] like Figure 3 As shown, in the technical solution of this embodiment, the pressure strip 600 includes a main body 620 and a rib 610. The main body 620 extends along the first direction Y and is at least partially connected to the portion of the top cover 212 exposed from the through hole 321. The rib 610 is connected to the side of the main body 620 facing the cover plate 102 and extends along the first direction Y. The dimension of the main body 620 along the third direction X is greater than the dimension of the rib 610 along the third direction X.

[0063] By setting the main body 620 to have a larger dimension along the third direction X, sufficient connection area can be ensured between the pressure strip 600 and the top cover 212, thereby improving the connection strength between the pressure strip 600 and the top cover 212. By setting the rib 610, on the one hand, the structural strength of the pressure strip 600 can be increased, reducing the probability of damage to the pressure strip 600 during handling, transportation, and assembly, and the pressure strip 600 is more effective in limiting the expansion range of the battery 210. On the other hand, the smaller dimension of the rib 610 along the third direction X can reduce the volume and weight of the pressure strip 600, thereby reducing production costs.

[0064] like Figure 3 and Figure 6 As shown, the battery pack 1 also has a third direction X intersecting the first direction Y and the second direction Z. The battery pack 1 includes a busbar 500, and the battery 210 also includes a terminal post 211, which is disposed through the top cover 212. The flexible circuit board 400 also includes an electrical signal acquisition terminal 402, which is connected to the terminal post 211.

[0066] By arranging the mounting portion 310, the busbar 500 can be mounted to realize the connection and fixation between the busbar 500 and the pole 211, and the isolation plate 300 can simultaneously bear a plurality of busbars 500, and then fix the plurality of busbars 500 and the plurality of batteries 210, thereby improving the assembly efficiency.

[0067] By arranging the connecting portion 320, the relative positions between the plurality of mounting portions 310 can be fixed, and a through hole 321 can be defined between two adjacent first connecting ribs 324, the receiving groove 326 is formed on the side of the first connecting rib 324 facing the battery pack 200, and the extension direction of the pressing piece 600 intersects with the extension direction of the first connecting rib 324, and further, the extension direction of the pressing piece 600 and the extension direction of the first connecting rib 324 can be perpendicular to each other, the pressing piece 600 supports the first connecting rib 324, reduces the probability of damage of the first connecting rib 324, and improves the structural strength of the connecting portion 320.
