It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0038] In the present disclosure, the orientation words such as "vertical direction" and the like used are defined based on the gravity of the battery itself, unless otherwise stated. In addition, the terms "first", "second" and the like used in the present disclosure are used to distinguish one element from another element, and do not have sequential and important meanings. In addition, in the following description, when referring to the drawings, the same reference numerals in different drawings represent the same or similar elements, unless otherwise explained. The above definitions are only for the explanation and illustration of the present disclosure, and should not be understood as a limitation of the present disclosure.

[0039] According to the specific embodiment of the present disclosure, a battery is provided, referring to the drawings shown in FIG. 1 to FIG. 6, the battery comprises a shell 4, a battery cell 42, a terminal assembly 45 and an adapter 44, the battery cell 42 is arranged in the shell 4, the terminal assembly 45 is at least partially arranged outside the shell 4, the shell 4 is provided with a recess 47, the recess 47 is arranged opposite to the terminal assembly 45 for accommodating the terminal assembly 45 of another battery, the adapter 44 comprises a tab fixing portion 441 and a pole fixing portion 442, the tab fixing portion 441 is connected with the tab portion 41 of the battery cell 42, the pole fixing portion 442 is connected with the terminal assembly 45, one end of the tab fixing portion 441 and one end of the pole fixing portion 442 are connected at an angle and form an opening, the opening is directed to the recess 47.

[0040] Through the above technical solution, in the battery provided by the present disclosure, the electrically conductive connection between the tab portion 41 of the battery cell 42 and the terminal assembly 45 is realized through the adapter 44, wherein the adapter 44 comprises the tab fixing portion 441 and the pole fixing portion 442 which are connected at an angle, and the opening is formed between the tab fixing portion 441 and the pole fixing portion 442, the opening is directed to the recess 47 formed by the shell 4, through the setting of the opening, the tab portion 41 of the battery cell 42 can extend into the opening to be connected with the tab fixing portion 441, and the pole fixing portion 442 is connected with the terminal assembly 45. Through the above design, the space occupied by the adapter 44 in the internal space of the shell 4 is small, so that the recess 47 formed by the shell 4 can be recessed to a greater extent towards the internal space of the shell 4, which is beneficial to provide a larger accommodation space for the terminal assembly 45 when the battery is stacked in groups, thereby reducing the influence on the welding between the pole and the bus bar, so as to solve the problem that the welding between the pole and the bus bar is not convenient due to the large space occupied by the adapter 44.

[0041] In the embodiment provided by the present disclosure, referring to the drawing shown in FIG. 1, part of the tab portion 41 extends from the battery cell 42 away from the recess 47 towards the adapter 44, and part of the tab portion 41 extends into the adapter 44 from the above-mentioned opening to be connected with the tab fixing portion 441. In this embodiment, the tab portion 41 does not need to be bent to be connected with the tab fixing portion 441, thereby avoiding the problem of stress concentration of the tab portion 41 due to bending.

[0042] In the embodiments provided in the present disclosure, the included angle formed between one end of the tab fixing portion 441 and one end of the pole fixing portion 442 can be greater than or equal to 60° and less than 180°. For example, in the embodiment shown in FIG. 1, the pole fixing portion 442 is in contact with the part of the terminal assembly 45 that extends into the shell 4. In this case, the pole fixing portion 442 can be parallel to the shell wall of the shell 4 where the terminal assembly 45 is arranged. Referring to the pole fixing portion 442, when the included angle between the tab fixing portion 441 and the pole fixing portion 442 is equal to 60°, the tab fixing portion 441 is bent away from the end of the pole fixing portion 442, i.e., the tab fixing portion 441 is inclined toward the side away from the battery cell 42. In this way, the overall size of the adapter 44 in the height direction of the battery is smaller, which is conducive to the recessed portion 47 being recessed to a greater extent toward the internal space of the shell 4, thereby providing a larger accommodation space for the terminal assembly 45 when the batteries are stacked in groups. When the included angle between the tab fixing portion 441 and the pole fixing portion 442 is equal to 90°, as shown in FIG. 1, the tab fixing portion 441 and the pole fixing portion 442 are perpendicular to each other. In other exemplary embodiments, the included angle between the tab fixing portion 441 and the pole fixing portion 442 can also be 100°, 110°, 120°, 135°, 150°, 160°, 175°, etc., which are not specifically limited in the present disclosure. When the included angle between the tab fixing portion 441 and the pole fixing portion 442 is greater than 90°, the tab fixing portion 441 is bent toward the battery cell 42 from the end of the pole fixing portion 442, i.e., the tab fixing portion 441 is inclined toward the side close to the battery cell 42. In this way, the overall size of the adapter 44 in the height direction of the battery is smaller, which is conducive to the recessed portion 47 being recessed to a greater extent toward the internal space of the shell 4, thereby providing a larger accommodation space for the terminal assembly 45 when the batteries are stacked in groups.

[0043] In the present disclosure, referring to FIGS. 3-5, the terminal assembly 45 can include a pole 451 and an isolation seat 452, the isolation seat 452 is arranged in the shell 4 and is provided with a through hole 453 for the pole 451 to pass through, the adapter 44 is insulated and isolated from the shell 4 by the isolation seat 452, and the pole 451 is fixed to the pole fixing portion 442 by passing through the shell 4 and the through hole 453.

[0044] By the technical solution, the adapter 44 is arranged to connect with the tab portion 41. In use, the tab portion 41 and the tab fixing portion 441 of the adapter 44 can be connected by a method including welding. Then, the pole 451 is arranged in the shell 4 and connected with the pole fixing portion 442 of the adapter 44. The power output line of the battery cell 42 is sequentially connected with the tab portion 41, the tab fixing portion 441, the pole fixing portion 442, and the pole 451. In this process, the isolation seat 452 insulates and protects the adapter 44 and the pole 451, avoiding short circuit caused by contact between the adapter 44 and the shell 4. In addition, in some embodiments of the present disclosure, the pole 451 can be further provided with an insulating plastic. The insulating plastic is wrapped around the outer periphery of the pole 451 to insulate and protect the pole 451. In use, the material of the pole 451 can be any high-conductivity material including nickel, aluminum, copper, and the like. The isolation seat 452 and the insulating plastic can be made of various insulating materials including PP (polyethylene) and PPS (polyphenylene sulfide), which are not limited in the present disclosure.

[0045] The isolation seat 452 can include a seat body 4521 and an extension wall 4522. The seat body 4521 is fixed to the shell 4 and forms a mounting groove 4520.

[0047] In the present disclosure, the adapter 44 can be constructed in any suitable form, such as a sheet or a plate, which is not limited in the present disclosure. When the adapter 44 is constructed as a plate, the adapter 44 can include a first plate body and a second plate body. The first plate body is used to connect the pole fixing portion 442 with the terminal assembly 45. The second plate body is connected to the first plate body and bent from the end of the first plate body at an angle with the first plate body. The second plate body is used to connect the tab fixing portion 441 with the tab portion 41 of the battery cell 42.

[0048] On the basis of the above technical solutions, referring to FIG. 2, the adapter 44 can further include a smooth transition part 443, which is arranged at the end of the second plate body away from the first plate body, and the smooth transition part 443 is formed with a smooth surface on the side facing the tab part 41, so that the adapter 44 can be prevented from scratching the tab part 41.

[0049] The smooth transition part 443 can be configured in any suitable manner. For example, a fillet can be formed at the end of the second plate body away from the first plate body, in which case the smooth transition part 443 is configured in the form of a fillet. For another example, the smooth transition part 443 can be configured as a curled edge, which is connected to the second plate body and curled from the end of the second plate body towards the battery cell 42. In actual use, the smooth transition part 443 can be configured in different ways according to the thickness of the adapter 44, for example, the smooth transition part 443 can be formed in the form of a curled edge when the thickness of the adapter 44 is less than 0.50 mm, and the smooth transition part 443 can be formed in the form of a fillet when the thickness of the adapter 44 is greater than 0.50 mm.

[0050] In the battery provided in the present disclosure, two battery support frames can be arranged in the housing 4, and the two battery support frames are arranged on both sides of the length direction of the battery cell 42, and the two battery support frames support and limit the battery cell 42 from both ends of the battery cell 42, so as to avoid the battery cell 42 from shaking and tearing the tab part 41 during installation of the battery.

[0051] Referring to FIG. 1, the terminal assembly 45 includes an isolation seat 452, and the battery support frame is arranged on the isolation seat 452, and part of the battery support frame abuts against the adapter 44, so as to facilitate arrangement of the battery support frame in the housing 4.

[0052] In the specific embodiment of the present disclosure, referring to FIG. 6, the battery support frame can include a connecting frame body 1 and two support seats 2, and the two support seats 2 are respectively connected to the two end portions of the connecting frame body 1. The support seat 2 has a first support surface 21 for supporting the battery cell 42 of the battery. An avoiding part 3 is formed between the support seat 2 and the connecting frame body 1, and the avoiding part 3 is used for avoiding the tab part 41 of the battery. An accommodation space 43 is formed between the connecting frame body 1 and the battery cell 42, and the tab part 41 is partially located in the accommodation space 43 through the avoiding part 3.

[0053] By the technical scheme, the support seat 2 supports the cell part when the battery pack is assembled, and the avoiding part 3 is formed between the support seat 2 and the connecting frame body 1 to accommodate the tab part 41. On the one hand, the support of the support seat 2 can effectively resist external force, and avoid the tab part 41 from being pulled due to the shaking of the cell and other parts. On the other hand, the avoiding part 3 formed can leave a certain amount of space for the tab part 41 when the tab part 41 is welded, so as to avoid the tab part 41 from being kept in a tense state after welding, thereby further avoiding stress concentration at the tab part 41, and solving the problem that the tab part 41 is easily torn and broken during the assembly of the battery pack.

[0054] In order to facilitate the connection of the tab part 41 and the adapter 44, a through hole is formed between the adapter 44 and the connecting frame body 1 to allow the tab part 41 to extend into the accommodation space 43. In addition, in order to meet the connection (such as welding) requirement of the tab part 41 and the adapter 44, the distance between the battery support frame and the adapter 44 is greater than the thickness of the tab part 41, and the distance between the battery support frame and the adapter 44 can be set according to actual requirements, for example, 1 mm, 1.5 mm, 2 mm, etc., and the present disclosure does not make specific limitations.

The first reinforcing rib 51 has a second support surface 511 flush with the first support surface 21 and commonly used for supporting the cell 42 of the battery. The configuration of the support seat 2 as a hollow shell seat can reduce the weight of the support seat 2 while ensuring a certain support effect, thereby reducing the weight of the battery pack itself, and the structure of the hollow shell seat can also have better heat dissipation effect. The first reinforcing rib 51 is arranged inside the hollow shell seat, which can enhance the strength of the support seat 2 on the one hand, and the second support surface 511 flush with the first support surface 21 can commonly support the cell 42 to enhance the support effect on the other hand. The structure of the support seat 2 and the first reinforcing rib 51 can be selected in any suitable manner according to actual requirements during specific use, and the present disclosure does not make specific limitations.
