Even if the battery cell module experiences high-intensity vibration, the first isolating member can prevent the unconnected pole ears on adjacent battery cells from contacting each other due to vibration or other situations, thereby causing a short circuit.

[0073] See also Figure 1 and Figure 2 A battery cell module 1 includes a plurality of battery cells 10, a collecting member 20, and a bracket 30. The plurality of battery cells 10 are stacked, and the battery cells 10 include a battery cell body 11 and a tab connected to the battery cell body 11. The collecting member is connected to the tab. Of the two adjacent battery cells 10, the first battery cell A includes a first tab 12 and a second tab 13, and the second battery cell B includes a third tab 14 and a fourth tab 15, and the first tab 12 is connected to the third tab 14. The bracket 30 includes a fixing plate 31 and a first isolating member 32 provided on the fixing plate 31. The collecting member 20 is provided between the fixing plate 31 and the battery cell body 11, and the first isolating member 32 is provided between the second tab 13 of the first battery cell A and the fourth tab 15 of the second battery cell B.

[0074] In this embodiment, the collecting member 20 is a flexible circuit board. It is understood that in other embodiments, the collecting member 20 can also be replaced by other structures with equivalent functions or effects, such as a collecting terminal.

[0075] See also Figure 2 、 Figure 3 and Figure 4, multiple battery cells 10 are stacked along a preset direction. In one embodiment, the battery cells 10 are arranged from top to bottom. The battery cell 10 includes the battery cell body 11 and the tabs. In this embodiment, two adjacent battery cells 10 are described. The two adjacent battery cells include a first battery cell A and a second battery cell B. The first battery cell A and the second battery cell B include the battery cell body 11. The first battery cell A also includes a first tab 12 and a second tab 13 provided on the battery cell body 11. The second battery cell B also includes a third tab 14 and a fourth tab 15 provided on the battery cell body 11. A third battery cell C is also provided on the side of the second battery cell B facing away from the first battery cell A. The third battery cell C includes a battery cell body 11 and a fifth tab 16 and a sixth tab 17 provided on the battery cell body 11. The battery cell body 11 is formed by placing a separator between two electrode sheets and then winding or stacking them. This technical content is relatively common in existing battery structures and will not be described in detail here.

[0076] In one embodiment, the first, fourth, and fifth tabs 12, 15, and 16 are positive tabs, while the second, third, and sixth tabs 13, 14, and 17 are negative tabs. It is understood that in other embodiments, the polarity of the first, fourth, and fifth tabs 12, 15, 16, and the second, third, and sixth tabs 13, 14, and 17 can be reversed. Between adjacent battery cells 10, the tabs on one battery cell 10 and the tabs on another battery cell 10 are positioned on the same side of their respective battery cell bodies 11, and the tabs are connected to connect the multiple battery cells 10. Specifically, the first tab 12 of the first battery cell A is connected to the third tab 14 of the second battery cell B, the fourth tab 15 of the second battery cell B is connected to the sixth tab 17 of the third battery cell C, and the fifth tab 16 extends away from the third tab 14. The other battery cells 10 are connected in the same manner to achieve series connection of the battery cells 10. In this embodiment, the first electrode tab 12 and the third electrode tab 14, and the fourth electrode tab 15 and the sixth electrode tab 17 are connected by welding.

[0077] See also Figure 2 and Figure 3 The collection member 20 is located on the side of the battery cell 10 where the tab is located. The collection member 20 includes a main body 21 and a collection sheet 22 located on the main body 21. The tabs on adjacent battery cells 10 are stacked and connected to the collection sheet 22 to collect voltage. In one embodiment, the tabs are welded to the collection sheet 22.

[0078] It is understandable that, in other embodiments, the tabs may be connected to the collection sheet 22 in other ways, such as by fastening the tabs to the collection sheet 22 with screws.

[0079] A plurality of collection pieces 22 are provided on the main body 21 , and two adjacent collection pieces 22 extend perpendicular to the main body 21 and in opposite directions, so that the collection pieces 22 can be connected to the first pole tab 12 , the second pole tab 13 , the third pole tab 14 , the fourth pole tab 15 , the fifth pole tab 16 and the sixth pole tab 17 on different battery cells 10 .

[0080] See also Figure 2 and Figure 3 In one embodiment, the battery cell module 1 further includes an adapter 25. The adapter 25 includes a connecting portion 251 and an adapter end 252. One end of the connecting portion 251 is connected to the main body 21 of the collecting member 20, and the other end of the connecting portion 251 is connected to the adapter end 252.

[0081] The connecting portion 251 is substantially perpendicular to the main body 21 and is disposed along the surface of the battery cell body 11 to reduce the overall volume of the battery cell module 1 .

[0082] The adapter end 252 is further provided with an electrical connector 253 so that the acquisition component 20 can be connected to an external electrical connector, such as an external circuit board 2 .

[0083] It is understood that in other embodiments, the adapter 25 and the collecting member 20 may be an integrally formed structure. Similarly, the collecting member 20 may be connected to an external electrical connector.

[0084] See also Figure 3 、 Figure 5 and Figure 6 The bracket 30 and the collecting member 20 are disposed on the same side of the battery cell 10, with the bracket 30 disposed on the side of the collecting member 20 facing away from the battery cell 10. The bracket 30 includes the fixing plate 31 and the first isolation member 32 disposed on the fixing plate 31. The first isolation member 32 extends toward the battery cell 10. Furthermore, the first isolation member 32 serves as a stopper.

[0085] The fixing plate 31 is provided with a groove 311 on a surface facing away from the first isolating member 32 , and the groove 311 is used to accommodate other structures.

[0086] In one embodiment, the first isolating member 32 is disposed between the second tab 13 and the fourth tab 15 of the adjacent first battery cell A and the second battery cell B to electrically isolate the unconnected second tab 13 and the unconnected fourth tab 15 from contact to avoid a short circuit.

[0087] In one embodiment, the bracket 30 further includes a second isolating member 33, which is disposed on the fixing plate 31. The fixing plate 31, the first isolating member 32, and the second isolating member 33 form a first receiving groove 34. The fourth tab 15 and the sixth tab 17 are received in the first receiving groove 34.

[0088] In one embodiment, the bracket 30 further includes a third spacer 35, which is also disposed on the fixing plate 31. The first spacer 32 is located between the third spacer 35 and the second spacer 33. The fixing plate 31, the third spacer 35, and the first spacer 32 form a second receiving groove 36. The third spacer 35 and the first spacer 32 can jointly separate the unconnected second electrode tab 13 and the unconnected fourth electrode tab 15 on the adjacent first battery cell A and the second battery cell B, thereby more effectively preventing the unconnected second electrode tab 13 and the unconnected fourth electrode tab 15 from contacting each other.

[0089] At least one of the first isolating member 32, the second isolating member 33 and the third isolating member 35 includes an insulating structure (not shown). In this embodiment, the fixing plate 31, the first isolating member 32, the second isolating member 33 and the third isolating member 35 are integrally molded from plastic. In other embodiments, the first isolating member 32 may be made of a non-insulating material, and in order to electrically isolate the unconnected tabs and avoid short circuits, the first isolating member 32 may be coated with an insulating material or an insulating member may be provided on the isolating member. Similarly, the second isolating member 33 and the third isolating member 35 may also be provided in this manner. In addition, an insulating member may be added between the tab and the first isolating member 32 for electrical isolation.

[0090] It is understood that in other embodiments, the bracket 30 may be provided with multiple first spacers 32 and second spacers 33 to accommodate the connected ground tabs and the collection sheet 22. The bracket 30 may also be provided with multiple third spacers 35 to cooperate with the first spacers 32 to separate the unconnected second tabs 13 and fourth tabs 15 on adjacent battery cells 10.

[0091] In another embodiment, only the first separator 32 may be provided to separate the second tab 13 on the first battery cell A from the fourth tab 15 on the adjacent second battery cell B. This configuration can make the bracket 30 simpler and the overall structure lighter.

[0092] See also Figure 2 and Figure 3 The battery cell module 1 also includes a connector 40 that connects to the tabs on the battery cells 10. The connector 40 includes a first connector 41 and a second connector 42. One end of the first connector 41 connects to the tab and the collection plate 22 on the bottommost battery cell 10, and the other end extends toward the uppermost battery cell 10. The first connector 41 is received in the groove 311 of the bracket 30 to prevent the first connector 41 from shaking during high-intensity vibration. In addition, the bracket 30 also supports the first connector 41. One end of the second connector 42 connects to the tab and the collection plate 22 on the uppermost battery cell 10, and the other end extends away from the uppermost battery cell 10. The first connector 41 connects to the positive tab on the battery cell 10, and the second connector 42 connects to the negative tab on the battery cell 10. It will be appreciated that in other embodiments, the polarity of the tabs connected by the first and second connectors 41 and 42 can be interchangeable.

[0093] The first connector 41 is provided with a safety zone 411. When the current exceeds a preset current, the first connector 41 will disconnect at the safety zone 411, thereby blocking the current and preventing a dangerous situation. In this case, the first connector 41 at the safety zone 411 acts as a fuse, improving the safety of the soft-pack battery cell 10 module.

[0094] To prevent the bracket 30 from being affected by high temperatures when the first connector 41 is disconnected in the safety zone 411, an isolation sheet 50 is provided in the safety zone 411. Furthermore, two isolation sheets 50 are provided in the safety zone 411, and the two isolation sheets 50 are attached to opposite surfaces of the first connector 41 to provide thermal insulation for the first connector 41 in the safety zone 411.

[0095] In one embodiment, after the first connector 41 extends toward the rightmost battery cell 10 , the other end of the second connector 42 is located on the same side of the battery cell 10 , which can reduce the volume occupied by the first connector 41 and the second connector 42 when they are extended, thereby reducing the overall volume of the battery cell module 1 .

[0096] See also Figure 7The battery cell module 1 further includes a baffle 60, which is provided on the outer surface of the battery cell 10 to protect the battery cell 10. The baffle 60 includes a plate body 61, and the shape of the plate body 61 is substantially the same as that of the battery cell body 11. The plate body 61 is provided with an opening 62 at the end position close to the tab, and the end of the connector 40 can extend from the opening 62. Furthermore, two openings 62 are provided on the plate body 61, and the end of the first connector 41 extends from one of the openings 62, and the end of the second connector 42 extends from the other opening 62.

[0097] In one embodiment, the baffle 60 further includes a limiting portion 63 disposed at the opening 62 to limit the first and second connecting members 41, 42, thereby preventing the ends of the first and second connecting members 41, 42 from dangling at the opening 62 during high-intensity vibration of the battery cell module 1, thereby affecting connection with other structures. Furthermore, the limiting portion 63 is a limiting post.

[0098] It is understandable that, in other embodiments, the limiting portion 63 may also be a limiting boss, and replacing the limiting column with a limiting boss may also serve to limit the first connecting member 41 and the second connecting member 42 .

[0099] The plate body 61 also defines a through-hole 64. The connecting portion 251 of the adapter 25 extends along the surface of the battery cell 10 near the baffle 60, and the adapter end 252 extends from the through-hole 64. The first connector 41 and the second connector 42 extending from the opening 62 and the adapter end 252 extending from the through-hole 64 are connected to the circuit board 2 disposed on the surface of the baffle 60.

[0100] See also Figure 2 、 Figure 3 and Figure 5 A first insulating member 70 is disposed in the first receiving groove 34 and is located between the fourth tab 15 and the sixth tab 17 . That is, the first insulating member 70 can be disposed between the connected tabs on adjacent battery cells 10 .

[0101] A second insulating member 71 is provided in the second receiving groove 36. The second insulating member 71 separates the unconnected second electrode tab 13 and the unconnected fourth electrode tab 15 of the adjacent first battery cell A and the second battery cell B, and can cooperate with the first isolating member 32 to prevent the unconnected second electrode tab 13 and the unconnected fourth electrode tab 15 from contacting each other.

[0102] A third insulating member 72 is provided between adjacent battery cells 10. When the battery cells 10 expand, the third insulating member 72 is deformed by compression, thereby preventing the battery cells 10 from squeezing the housing. Specifically, the third insulating member 72 is provided between two adjacent battery cell bodies 11. Furthermore, to better protect the battery cell module 1, insulating members (not shown) are provided around the stacked battery cells 10. In the event of a collision, the insulating members can act as a buffer for the battery cells 10.

[0103] Furthermore, an insulating sheet 80 is provided on the third insulating member 72 between the baffle 60 and the battery cell 10. The insulating sheet 80 is located between the baffle 60 and the third insulating member 72. The adapter end 252 is fixed to the insulating sheet 80 by bonding, so that the end of the adapter 25 is fixed and prevented from shaking.

[0104] In one embodiment, the first insulating member 70, the second insulating member 71, the third insulating member 72 and the insulating members provided around the stacked battery core 10 are foam. It is understood that in other embodiments, other structures with equivalent functions or effects may be substituted.

[0105] Please refer to Figure 2 and Figure 3 The battery cell module 1 further includes a colloid 90, which is disposed around the stacked battery cells 10 to protect the battery cells 10. In one embodiment, the stacked battery cells 10 can be placed in a device, and the flowing colloid 90 can be filled from the opening 62 of the baffle 60. After the colloid 90 is formed and fixed, the battery cells 10 can be removed.

[0106] The first insulating member 70 and the second insulating member 71 are respectively disposed in the first receiving groove 34 and the second receiving groove 36 , which can fill the positions originally required to be filled by the colloid 90 , thereby reducing the overall weight of the battery module 1 .

[0107] In another embodiment, a battery pack (not shown) is provided. The battery pack includes a housing (not shown) and the battery cell module 1 described in the above embodiment. The battery cell module 1 is housed within the housing, with the colloid 90 positioned between the battery cell 10 and the housing. The battery employing the above-described battery cell module 1 exhibits corresponding beneficial effects, which will not be further described herein.

[0108] In summary, the battery cell module 1 provided in the embodiment of the present application can replace the adapter plate in the original module by adopting the collection piece 20 and the bracket 30. The collection piece 20 is connected to the pole ear, which can effectively reduce the pulling force on the pole ear. The bracket 30 includes a first isolating piece 32, which can electrically isolate the unconnected second pole ear 13 and the fourth pole ear 15 to avoid contact between the two and cause a short circuit. When the battery cell module 1 is used in some smart home devices such as sweeping robots, vacuum cleaners, circular saw cutting machines, etc., even under high-intensity vibrations, the unconnected second pole ear 13 and the fourth pole ear 15 will not come into contact with each other. At the same time, the bracket 30 is light in weight and low in cost, which reduces the weight of the battery cell module 1 and reduces the cost required during the assembly process.

[0109] In addition, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of protection claimed in the present application.
