[0034] The support frame 100 according to the first embodiment of the present application is described below with reference to the accompanying drawings.

[0035] The support frame 100 is used to accommodate multiple single cells 200, including an opening frame 110 and a partition assembly. The opening frame 110 is provided with a first opening 1131 and a second opening 1132. The partition assembly includes a first partition 120 and a second partition 130. The first partition 120 and the second partition 130 are both fixedly connected to the opening frame 110. The first partition 120 and the second partition 130 define a first channel 140. Multiple partition assemblies are spaced apart along a first direction and are used to separate adjacent single cells. The first opening 1131 and the second opening 1132 are located on both sides of the first partition 120, and the airflow can enter the opening frame 110 through the first opening 1131, and be discharged through the second opening 1132 after flowing in the first channel 140.

[0036] Specifically, Figures 1 to 3 As shown, the opening frame 110 includes a bottom member 113, two first side members 111 disposed opposite to each other, and two second side members 112 disposed opposite to each other. The first side members 111 extend along the X direction, and the second side members 112 extend along the Y direction. The X direction is the stacking direction of the single battery 200 (i.e., the first direction), which is also the length direction of the support frame 100, and the Y direction is the width direction of the support frame 100. Figure 1As shown, the partition assembly includes a first partition 120 and a second partition 130. The first partition 120 is fixedly connected to the bottom member 113, and the second partition 130 is fixedly connected to the first side member 111. There is a spacing between the first partition 120 and the second partition 130, that is, a first channel 140 is formed between the first partition 120 and the second partition 130. A plurality of partition assemblies are arranged at intervals along the first direction. The partition assemblies divide the opening frame 110 into a plurality of sub-spaces, and the single cells are placed in the sub-spaces, so that the support frame 100 can accommodate (or support) a plurality of single cells. Adjacent single cells are separated by partition assemblies, so that adjacent single cells are not in direct contact. The bottom member 113 is provided with a first opening 1131 and a second opening 1132. In the Y direction, the first opening 1131 and the second opening 1132 are located on both sides of each first partition 120. The specific structure of the first opening 1131 and the second opening 1132 can be an integrated opening structure, that is, the bottom member 113 has only one first opening 1131 and one second opening 1132, the first opening 1131 is a long strip opening, and both sides of all first partitions 120 have the first opening 1131 and the second opening 1132. It can be understood that the first opening 1131 and the second opening 1132 can be a plurality of openings distributed at intervals, and the number of the first openings 1131 and the number of the second openings 1132 are the same as the number of the first partitions 120, so that each first partition 120 has one first opening 1131 and one second opening 1132 on both sides.

[0037] The first partition 120 and the second partition 130 in each partition assembly define a first channel 140, and there is a set interval between the first partition 120 and the second partition 130. When all the single cells 200 are placed in the support frame 100, due to the setting of the partition assembly, there is a certain distance between two adjacent single cells 200. That is, air can enter from one of the first opening 1131 and the second opening 1132, pass through the first channel 140, and flow out from the other of the first opening 1131 and the second opening 1132, so that air can flow between adjacent single cells 200. In the process of air flowing in the first channel 140, it can contact the surfaces of two adjacent single cells 200, exchange heat with the single cells 200, thereby taking away the heat of the single cells 200 and cooling the single cells 200. The first partition 120, the second partition 130 and the opening frame 110 work together to fix the single cell 200 in the subspace of the opening frame 110. Through the arrangement of the above structure, the single cell 200 can be fixed more firmly, effectively preventing the single cell 200 from shaking in the battery module.

[0038] This embodiment shows that the structure of the support frame 100 is that the first partition 120 is fixedly connected to the bottom member 113. In other embodiments, the structure of the support frame 100 may be that the first partition 120 is fixedly connected to a first side member 111, and the corresponding first opening 1131 and second opening 1132 are also provided on the first side member 111.

[0039] By adopting the support frame 100 of the above structure to support multiple single cells 200, the assembly process of the battery module can be simplified. The single cells can be directly placed in the subspace of the opening frame 110, which can reduce the cumulative error in the stacking process of the single cells 200, thereby improving the assembly accuracy of the battery module. Furthermore, an air flow channel can be formed between adjacent single cells 200, thereby improving the heat dissipation performance of the battery module.

[0040] In some specific embodiments of the present application, the second partition 130 includes a first partition 131 , a second partition 132 and a third partition 133 , the first partition 131 and the second partition 132 are arranged opposite to each other, and the third partition 133 connects the first partition 131 and the second partition 132 .

[0041] Specifically, the second partition 130 is in a door frame structure as a whole, the first partition 131 and the second partition 132 are arranged opposite to each other, one end of the third partition 133 is fixedly connected to the end of the first partition 131, and the other end of the third partition 133 is fixedly connected to the end of the second partition 132. The first partition 120 is placed inside the door frame, and there is a certain distance between the first partition 131, the second partition 132 and the third partition 133. When the first partition 120 is fixedly connected to the bottom member 113, the first partition 131 of the second partition 130 is fixedly connected to one first side member 111, the second partition 132 of the second partition 130 is fixedly connected to the other first side member 111, and the third partition 133 of the second partition 130 is flush with the top of the opening frame 110. When the first separator 120 is fixedly connected to the first side member 111, the first separator 131 of the second separator 130 is fixedly connected to the bottom member 113, the third separator 133 of the second separator 130 is fixedly connected to the other first side member 111, and the second separator 132 of the second separator 130 is flush with the top of the opening frame 110. Through the above arrangement, the second separator 130, the first separator 120 and the opening frame 110 work together to support or support multiple positions of the single battery 200, thereby stably fixing the single battery 200 in the opening frame 110, effectively preventing the single battery 200 from shaking, and thus improving the safety of the battery module. The above-mentioned embodiment shows that the second partition 130 is a door frame type structure with three partitions. It can be understood that in some other embodiments, the second partition 130 only includes a first partition 131 and a second partition 132. The first partition 131 and the second partition 132 are arranged opposite to each other. The first partition 131 is fixedly connected to a first side member 111, and the second partition 132 is fixedly connected to the other first side member 111. The first side member 111 forms a card slot with the two adjacent first partitions 131 thereon, which is used to clamp one side of the single cell 200, and the other first side member 111 forms a card slot with the two adjacent first partitions 131 thereon, which is used to clamp the other side of the single cell 200, thereby fixing the single cell 200.

[0042] In some specific embodiments of the present application, an elastic component 150 is further included. The elastic component 150 is disposed on the second separator 130 . The elastic component 150 extends out of the second separator 130 along the first direction. The elastic component 150 is used to abut against the single battery 200 .

[0043] Specifically, Figures 4 to 7As shown, the elastic component 150 is arranged on the second separator 130, and along the first direction (i.e., the X direction, which is also the stacking direction of the single battery), the elastic component 150 extends to both sides of the second separator 130 to abut against the single battery 200. Since the single battery 200 will expand due to heat during the charging and discharging process, in order to ensure the working performance of the single battery 200 and avoid the occurrence of thermal runaway due to the lack of expansion space, along the X direction, the distance between two adjacent second separators 130 is slightly larger than the thickness of the single battery 200 in the X direction, thereby providing a certain expansion space for the single battery 200. However, since the distance between two adjacent second separators 130 is larger than the thickness of the single battery 200, the single battery 200 may shake. In order to ensure the stability of the single battery 200, the elastic component 150 is arranged on the second separator 130. When the single battery 200 is not expanded, the elastic component 150 abuts against the single battery 200, thereby fixing the single battery 200. When the single battery 200 expands, the single battery 200 applies force to the elastic component 150, causing the elastic component 150 to deform elastically, thereby allowing the single battery 200 to abut against the second separator 130. The above arrangement can provide a certain expansion space for the single battery 200 and ensure the stability of the single battery 200.

[0044] In some specific embodiments, Figure 7 As shown, the elastic component 150 includes a first abutting portion 151 and a second abutting portion 152. The first abutting portion 151 and the second abutting portion 152 are arranged opposite to each other and have a gap. Along the stacking direction of the single cells 200 (i.e., along the X direction), the first abutting portion 151 and the second abutting portion 152 extend out of the second partition 130. When the single cells 200 do not expand, there is a certain gap between the single cells and the second partition 130. Two adjacent single cells 200 abut against the first abutting portion 151 and the second abutting portion 152, respectively. When the single cells 200 expand, the two adjacent single cells 200 squeeze the first abutting portion 151 and the second abutting portion 152, respectively. The first abutting portion 151 and the second abutting portion 152 are elastically deformed, i.e., they move closer to each other in the X direction, so that the single cells 200 can abut against the second partition 130. By setting the elastic component, the single cells 200 can avoid shaking due to the gap when the temperature is low, and have expansion space when the temperature is high. Figures 4 to 6As shown in , when the second partition 132 is a door-type structure, an elastic component 150 is respectively provided at the lower end of the first partition 131 and the second partition 132, and two elastic components 150 are provided at intervals below the third partition 133. It is understood that the elastic components 150 on the first partition 131 and the second partition 132 can also extend along the Y direction, that is, the elastic component 150 on the first partition 131 extends out of the first partition 131 and extends toward the second partition 132, and the elastic component 150 on the second partition 132 extends out of the second partition 132 and extends toward the first partition 131. It is understood that the number of elastic components 150 on the second partition 130 can be set according to the size of the single battery 200.

[0045] In some specific embodiments of the present application, the connection between the second partition 130 and the opening frame 110 is connected by an arc transition.

[0046] Specifically, Figure 2 It is shown that the first partition 131 of the second partition 130 is fixedly connected to the first side member 111 on one side, and the connection between the first partition 131 and the first side member 111 is provided with a rounded corner, that is, the two are transitioned through a circular arc. Similarly, the second partition 132 is fixedly connected to the first side member 111 on the other side, and the connection between the second partition 132 and the first side member 111 on the same side is provided with a rounded corner, that is, the two are transitioned through a circular arc. In some other embodiments, when the first partition 120 is set on a first side member 111, the part where the second partition 130 is connected to the first side member 111 and the part where the second partition 130 is connected to the bottom member 113 are both connected through a circular arc transition. In the above manner, the accommodating cavity formed between the first side member 111, the bottom member 113 and the second partition 130 can better match the shape of the single battery 200, and can also avoid stress concentration in the opening frame 110, improve the structural strength of the opening frame 110, and thus improve the safety of the battery module.

[0047] In some specific embodiments of the present application, at least part of the outer edge of the first partition 120 is arc-shaped. Figure 4 As shown, in the YZ plane, the outer edge of the first partition 120 is an arc-shaped structure as a whole, and air flows in through one of the first opening 1131 and the second opening 1132, flows along the outer edge of the first partition 120, and then flows out through the other of the first opening 1131 and the second opening 1132, so that the air path is U-shaped. It can be understood that in other embodiments, such as Figure 5As shown, in the YZ plane, the outer edge of the first partition 120 is fan-shaped, and air flows in through one of the first opening 1131 and the second opening 1132, flows along the outer edge of the first partition 120, and then flows out through the other of the first opening 1131 and the second opening 1132. The air path is also roughly U-shaped. Figure 6 As shown, in the YZ plane, the outer edge of the first separator 120 is composed of a square portion (which is a square or a rectangle) and an arc portion, and the air flows along the edge of the first separator 120, and the air path is U-shaped. By setting the first separator 120 as the above structure, when the air flows along the outer edge of the first separator 120, the resistance of the air flow can be reduced, thereby increasing the speed of the air flow, and further improving the cooling effect. In some specific embodiments, when the first separator 120 is fixedly mounted on the bottom member 113, the height of the first separator 120 along the Z direction does not exceed half of the height of the single battery 200 along the Z direction; when the first separator 120 is fixed on a first side member 111, the length of the first separator 120 along the Y direction does not exceed half of the length of the single battery 200 along the Y direction. Since the middle area of ​​the single battery 200 expands the most during the charging and discharging process of the single battery 200, the air can flow through the middle area of ​​the single battery 200, so that the middle part of the single battery 200 can also be cooled, thereby improving the heat dissipation performance of the battery module.

[0048] In some specific embodiments of the present application, there are multiple opening frames 110 , and the multiple opening frames 110 are arranged along the second direction, wherein the first direction is the length direction of the support frame 100 , and the second direction is the width direction of the support frame 100 .

[0049] Specifically, Figure 1 The support frame 100 shown in FIG. 1 can only accommodate a row of single cells stacked along the X direction (i.e., the length direction of the support frame). It can be understood that, according to actual needs, multiple single cells can be stacked in the same row. Figure 1 The opening frame 110 shown in FIG. 1 is arranged along the width direction of the support frame 100 (ie Figure 1 The plurality of opening frames 110 are arranged in the Y direction shown in the figure, and form an integrated opening frame. Partition components (first partition 120 and second partition 130) are arranged in each opening frame 110 along the X direction. The first partition 120 in each opening frame 110 is fixedly connected to the bottom member 113 of the opening frame 110, and the second partition 130 in each opening frame 110 is fixedly connected to the first side member 111 of the opening frame 110, thereby forming an integrated support frame 100. Each opening frame 110 can accommodate a row of single cells. When the support frame 100 is full of single cells 200, the single cells 200 are distributed in a rectangular array in the support frame 100.

[0050] In some specific embodiments of the present application, the first partition components are arranged in multiple rows, and the multiple rows of first partition components are arranged at intervals along the second direction, and the second direction is the width direction of the support frame.

[0051] Specifically, the support frame has an opening frame 110, in which a plurality of columns of partition components are arranged, and the plurality of columns of partition components are arranged along the width direction (i.e. Figure 1 The number of columns of the partition assembly can be 2, and the first partitions 120 in the 2 columns of the partition assembly can be simultaneously arranged on the bottom member 113 of the opening frame 110. The first partitions 120 in the 2 columns of the partition assembly can also be that the first partitions 120 in one column are arranged on one first side member 111, and the first partitions 120 in the other column are arranged on the other first side member 111. The support frame 100 with 2 columns of partition assemblies can be used to place 2 columns of single cells (the 2 columns of single cells are distributed along the width direction of the support frame 100), and the first partitions 120 and the second partitions 130 in the partition assembly are both used to separate adjacent single cells in each column of single cells. It can be understood that the partition assembly can also be more than 3 columns. When the number of columns of the partitioning components is more than 3, the first partitions 120 in the partitioning components in more than 3 columns can be simultaneously arranged on the bottom member 113 of the opening frame 110, or the first partitions 120 in the two columns of the partitioning components on both sides in the width direction can be respectively arranged on the first side members 111 on the corresponding sides, and the first partitions 120 in the partitioning components in the remaining columns are all arranged on the bottom member 113 of the opening frame 110. The support frame 100 with more than 3 columns of partitioning components can be used to place more than 3 columns of single cells, and the first partitions 120 and the second partitions 130 in each column of the partitioning components are used to separate adjacent single cells in each column of single cells.

[0052] The battery module of the second embodiment of the present application includes a plurality of single cells and the support frame 100 of the first embodiment. The partition assembly (the first partition 120 and the second partition 130) divides the opening frame 110 into a plurality of subspaces, and places the single cells in the subspaces of the opening frame 110, thereby completing the assembly of the battery module. Compared with the battery module formed by stacking batteries, the battery module of the present application can reduce the stacking error and improve the assembly accuracy of the battery module. Since the first channel 140 is formed between the first partition 120 and the second partition 130, there is a gap between the single cell and the support frame, and the airflow can flow in the above gap (i.e., the first channel 140), thereby improving the heat dissipation performance of the battery module.

[0053] Specifically, Figure 2 and Figure 4As shown, when the first partition 120 in the partition assembly is fixedly installed with the bottom member 113, the outer sides of the two first side members 111 are provided with side mounting plates 400, and the side mounting plates 400 are L-shaped structures, and have a first mounting portion 410 and a second mounting portion 420, the first mounting portion 410 is fixedly connected to the first side member 111, and the second mounting portion 420 is used to be fixedly connected to the battery pack housing. By providing a mounting plate on the outer side of the support frame 100, it is possible to facilitate the installation of the battery module on the battery pack housing. In some specific embodiments, a through hole 160 is provided on the first side member 111, and the first side member 111 and the side mounting plate 400 are fixed by adhesive bonding. The first side member 111 is provided with a plurality of through holes 160. The number of through holes 160 on the first side member 111 on each side is the same as the number of single cells 200. During the assembly of the battery module, the single cells 200 are first placed in the subspace inside the support frame 100, and then glue is applied on the first side member 111. After that, the side mounting plate 400 is placed on the outside of the first side member 111. The glue fixes and connects the single cells 200, the first side member 111 and the side mounting plate 400. Through the above arrangement, the single cells 200 are fixedly connected to the support frame 100, and the single cells are not easy to shake relative to the support frame 100.

[0054] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
