[0029] Particular embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings. It should be understood that particular embodiments described herein are merely illustrative and explanatory of the present disclosure and are not intended to limit the present disclosure.

[0030] In this disclosure, unless stated otherwise, directional terms such as "upper" and "lower" generally refer to upper and lower positions of the adapter structure when assembled to the battery pack under normal operating conditions, and "inner" and "outer" refer to inner and outer positions relative to the contours of the corresponding component itself. Additionally, terms such as "first," "second," etc., as used in this disclosure are intended to distinguish one element from another and do not imply any order or importance.

[0031] According to certain embodiments of the present disclosure, an adapter structure is provided for a battery pack, particularly for electrically connecting output terminals of battery cell assemblies 6 in the battery pack to a distribution box 7. Battery cell assemblies 6 typically have all positive output terminals and all negative output terminals. In certain embodiments of the present disclosure, one of the all positive output terminals and all negative output terminals is referred to as a first output terminal, and the other is referred to as a second output terminal. With reference to FIGS. 1 to 4 , the adapter structure may include a first adapter 1, a second adapter 2, and an insulating bracket 3. The first adapter 1 may include a first flex structure 10 electrically connected between a first output terminal (not shown) of the battery cell assembly 6 and the distribution box 7. The first flex structure 10 advantageously electrically connects the first output terminal and the distribution box 7, which have a vertical height difference. The second adapter 2 may be spaced apart from the first adapter 1 to maintain insulation therebetween. The second adapter 2 may include a second output pole (not shown) electrically connected between a second output pole (not shown) of the battery cell assembly 6 and the distribution box 7. This second flex structure 20 makes it convenient to electrically connect the second output pole and the distribution box 7, which are at different heights in the vertical direction. The first flex structure 10 and the second flex structure 20 may pass through the insulating bracket 3 to insulate the first adapter 1 and the second adapter 2 from each other.

[0032] According to the above technical solution, the adapter structure provided by the present disclosure includes a first adapter 1, a second adapter 2, and an insulating bracket 3. The first flex structure 10 of the first adapter 1 and the second flex structure 20 of the second adapter 2 are kept insulated from each other by the insulating bracket 3. In addition, the first flex structure 10 and the second flex structure 20 can electrically connect the first output pole and the second output pole, which is positioned lower in the vertical direction, to the distribution box, which is positioned higher, and can also reduce the space occupied by the first adapter 1 and the second adapter 2 in the battery pack, thereby improving the internal space utilization of the battery pack. Therefore, the adapter structure provided by the present disclosure can simplify the related structure for electrically connecting the output pole of the battery cell assembly 6 to the distribution box 7, thereby facilitating the electrical connection of the output pole of the battery cell assembly 6 to the distribution box 7.

[0033] 3 and 4 , in order to maintain mutual insulation between the first adapter 1 and the second adapter 2 by the insulating bracket 3, the insulating bracket 3 may include a support 30, a first cantilever beam 31 and a second cantilever beam 32 extending outward from the periphery of the support 30, and a cross beam 33 connected to the upper end of the support 30. The first cantilever beam 31 may extend to the first bending structure 10 such that the first bending structure 10 passes between the first cantilever beam 31 and the cross beam 33; that is, the portion of the first bending structure 10 that passes through the insulating bracket 3 may be covered by the first cantilever beam 31 and the cross beam 33. The second cantilever beam 32 can extend into the second bending structure 20 so that the second bending structure 20 passes between the second cantilever beam 32 and the cross beam 33, i.e., the portion of the second bending structure 20 that passes through the insulating bracket 3 can be covered by the second cantilever beam 32 and the cross beam 33. The first cantilever beam 31 and the second cantilever beam 32 extend in opposite directions so that the first bending structure 10 and the second bending structure 20 can be separated by the support 30, thereby keeping the first adapter 1 and the second adapter 2 in an insulated state.

[0034] 3 and 4 , to form the first bent structure 10, the first adapter 1 may include a first battery cell adapter plate 11, a first distribution box adapter plate 12, and a first connection plate 13. The first battery cell adapter plate 11 may extend vertically and may be disposed on a side of the insulating bracket 3 facing the battery cell assembly 6 so as to be electrically connected to the first output pole. The first distribution box adapter plate 12 may extend parallel to and be spaced apart from the first battery cell adapter plate 11 and may be disposed on a side of the insulating bracket 3 facing the distribution box 7 so as to be electrically connected to the distribution box 7. The first connection plate 13 may be connected between the first battery cell adapter plate 11 and the first distribution box adapter plate 12. The first connecting plate 13 can extend horizontally such that the first battery cell adapter plate 11, the first connecting plate 13, and the first distribution box adapter part 12 are circumferentially arranged to form the first bent structure 10. The first connecting plate 13 can pass between the first cantilever beam 31 and the cross beam 33 and can be covered by the first cantilever beam 31 and the cross beam 33. To make the volume and structure of the adapter structure smaller and more compact, the first battery cell adapter plate 11 can be attached to the surface of the first cantilever beam 31 facing the battery cell assembly 6, and the first distribution box adapter plate 12 can be attached to the surface of the first cantilever beam 31 facing the distribution box 7.

[0035] 3 and 4, the adapter structure may further include a first electrode connection plate 4 electrically connected between the side of the first battery cell adapter plate 11 facing the battery cell assembly 6 and the first output pole. The first electrode connection plate 4 may be made of an aluminum material, and the first adapter 1 may be made of a copper material. The first electrode connection plate 4 and the first battery cell adapter plate 11 may be permanently joined by welding.

[0036] 3 and 4 , to form the second flex structure 20, the second adapter 2 may include a second battery cell adapter plate 21, a second distribution box adapter plate 22, and a second connection plate 23. The second battery cell adapter plate 21 may extend vertically and may be disposed on the side of the insulating bracket 3 facing the battery cell assembly 6 so as to be electrically connected to the second output pole. The second distribution box adapter plate 22 may extend parallel to the second battery cell adapter plate 21 and be spaced apart from the second battery cell adapter plate 21. The second connection plate 23 may be connected between the second battery cell adapter plate 21 and the second distribution box adapter plate 22. The second connection plate 23 can extend horizontally such that the second battery cell adapter plate 21, the second connection plate 23, and the second distribution box adapter part 22 are circumferentially arranged to form the second flexure structure 20. The second connection plate 23 can pass between and be covered by the second cantilever beam 32 and the cross beam 33. To make the volume and structure of the adapter structure smaller and more compact, the second battery cell adapter plate 21 can be attached to the surface of the second cantilever beam 32 facing the battery cell assembly 6, and the second distribution box adapter plate 22 can be attached to the surface of the second cantilever beam 32 facing the distribution box 7.

[0037] 3 and 4, the adapter structure may further include a second electrode connection plate 5 electrically connected between the side of the second battery cell adapter plate 21 facing the cell assembly 6 and the second output pole. The second electrode connection plate 5 may be made of an aluminum material, and the second adapter 2 may be made of a copper material. The second electrode connection plate 5 and the second battery cell adapter plate 21 may be permanently joined by welding.

[0038] As shown in FIGS. 1 and 2 , a protective cover 8 for protecting the electrodes of the battery cell assembly 6 is usually disposed at the end of the battery cell assembly 6. The protective cover 8 is located between the battery cell assembly 6 and the distribution box 7. The insulating bracket 3 can be fitted into an escape opening 81 in the protective cover 8 that corresponds to one end of the central beam 9. As shown in FIG. 3 , in order to prevent the insulating bracket 3 from moving, a buckle 302 that protrudes toward the central beam 9 is disposed on the side of the support 30 that faces the battery cell assembly 6. The buckle 302 can be used to clamp and secure the central beam 9 for easy disassembly and assembly of the insulating bracket 3.

[0039] As shown in FIG. 3 , to facilitate positioning of the insulating bracket 3 and the central beam 9, a plug-in boss 303 protruding toward the central beam 9 may be disposed on the side of the support 30 facing the battery cell assembly 6. The plug-in boss 303 is used for insertion into the central beam 9. Specifically, a socket for inserting the plug-in boss 303 may be disposed on the end face of the central beam 9. To increase the reliability of the connection between the insulating bracket 3 and the central beam 9, one end of the plug-in boss 303 may form a guide inclined portion 307, so that the plug-in boss 303 can be tightly fitted into the socket of the central beam 9.

[0040] In addition, the buckle 302 and the insertion boss 303 can further increase the reliability of the insulation between the first battery cell adapter plate 11 and the second battery cell adapter plate 21 .

[0041] Accordingly, as shown in Figure 4, an insulating boss 301 protruding toward the distribution box 7 is arranged on the side of the support 30 facing the distribution box 7 so as to separate the first adapter 1 and the second adapter 2, thereby further increasing the reliability of the insulation between the first distribution box adapter plate 12 and the second distribution box adapter plate 22.

[0042] As shown in FIG. 4 , the insulating boss 301 may be formed with a first limiting boss 304 that protrudes toward the first adapter 1 and is inserted into the first adapter 1, and a second limiting boss 305 that protrudes toward the second adapter 2 and is inserted into the second adapter 2, in order to prevent the first adapter 1 and the second adapter 2 from easily moving when connected to the distribution box 7 and to improve the accuracy of assembly and reliability of connection between the first adapter 1 and the second adapter 2 and the distribution box 7.

[0043] 5, a first routing groove 306 for the sampling wire harness 101 to pass through may be formed between the insulating boss 301 and the lower end of the support post 30. Specifically, the insulating boss 301 may form the first routing groove 306 between the following two support legs 34 to simplify routing of the sampling wire harness, reduce the length of the sampling wire harness, and improve the internal space utilization of the battery pack.

[0044] Typically, a plastic bracket 82 is disposed in the escape opening 81 of the protective cover 8. As shown in FIG. 6 , two splayed support legs 34 are disposed at the lower end of the support post to facilitate assembly of the insulating bracket 3 and the plastic bracket 82. The two support legs 34 are supported by the plastic bracket 82 and are used to meet strength requirements after assembly of the insulating bracket 3 and the plastic bracket 82. To simplify routing and improve space utilization inside the battery pack, wire-through holes 35 may also be formed between the two support legs 34 and the plastic bracket 82, through which a drive power lead-out harness (not shown) can pass.

[0045] In addition, as shown in Figures 3 and 7, a second routing groove 331 is formed on the upper surface of the cross beam 33 for passing the low-voltage wire harness 102, so that the low-voltage wire harness 102 can pass through the insulating bracket 3 and reach the routing channel of the central beam 9 via the shortest route.

[0046] Generally, the first and second output poles are disposed on opposite sides of the central beam 9 with a vertical height difference therebetween. In certain embodiments of the present disclosure, the output pole with a higher position is used as the first output pole, and the output pole with a lower position is used as the second output pole. Accordingly, the vertical position of the first adapter 1 for connecting with the first output pole is higher than the vertical position of the second adapter 2 for connecting with the second output pole. Therefore, the upper surface of the first cantilever beam 31 can be higher than the upper surface of the second cantilever beam 32. That is, the distance between the upper surface of the first cantilever beam 31 and the transverse beam 33 is smaller than the distance between the upper surface of the second cantilever beam 32 and the transverse beam 33.

[0047] 3 and 4 , to make the structure of the insulating bracket 3 more compact, the second routing groove 331 can be disposed in the cross beam 33 at a position corresponding to a position above the second cantilever beam 32, so that the second adapter 2 is clamped between the bottom of the second routing groove 331 and the second cantilever beam 32. That is, the space between the second cantilever beam 32 and the cross beam 33 can be used to dispose the second routing groove 331, and the bottom of the second routing groove 331 can also serve as a limit for the second adapter 2. Accordingly, in order to limit the first adapter 1, a third limiting boss 332 protruding toward the first cantilever beam 31 can be formed on the lower surface of the cross beam 33 at a position corresponding to a position above the first cantilever beam 31, so that the first adapter 1 is clamped between the third limiting boss 332 and the first cantilever beam 31. The third limiting boss 332 and the second routing groove 331 cooperate with the first limiting boss 304 and the second limiting boss 305 to further improve the assembly accuracy and connection reliability of the first adapter 1 and the second adapter 2 with the distribution box 7.

[0048] In addition, as shown in Figures 3 and 7, the side of the cross beam 33 facing the distribution box 7 may be formed with a flange 333 extending toward the distribution box 7. The flange 333 is used to overlap the upper surface of the distribution box 7 in order to further improve the positioning accuracy and connection stability between the insulating bracket 3 and the distribution box 7.

[0049] 3 and 8, the side of the cross beam 33 facing the battery cell assembly 6 is formed with a clearance groove 334 for avoiding the liquid inlet hole 61 of the battery cell assembly 6. This clearance groove 334 not only provides a space for the liquid inlet hole 61, but also protects the liquid inlet hole 61.

[0050] Based on the above technical solution, the present disclosure also provides a battery pack as shown in Figures 1 and 2. The battery pack may include a battery cell assembly 6, a central beam 9 extending parallel to the battery cell assembly 6, a distribution box 7 disposed at one end of the battery cell assembly 6, and a protective cover 8 disposed between the battery cell assembly 6 and the distribution box 7. A clearance opening 81 is disposed in the protective cover 8 corresponding to one end of the central beam 9. The battery pack may also include the adapter structure in the above technical solution, in which the insulating bracket 3 is fitted into the clearance opening 81.

[0051] According to the above technical solution, the battery pack provided in the present disclosure has the same technical effect as the adapter structure in the above technical solution, which will not be described in detail hereinafter to avoid unnecessary repetition.
