[0044] The existing cell support structure lacks an automatic heat dissipation layout, which causes heat to accumulate in the battery pack during high-intensity discharge, resulting in low heat dissipation efficiency, which accelerates battery aging and poses safety hazards.

[0045] This application specifically discloses a battery cell support, which includes a first housing 100, a second housing 200, a connector 300, and a barrier 400.

[0046] See Figure 1 and Figure 2 As shown, there are two first housings 100 and multiple second housings 200. Furthermore, multiple second housings 200 are located between two first housings 100. A receiving cavity is formed between the first housings 100 and the second housings 200 and between two adjacent second housings 200. The receiving cavity is used to accommodate the battery cell.

[0047] The first housing 100 has two parts located on both sides, and a plurality of second housings 200 are evenly arranged between the two first housings 100. The accommodating cavity formed between two adjacent second housings 200 is used to accommodate the battery cell, and an accommodating cavity is also formed between the first housing 100 at the far end and the second housing 200, which is also used to accommodate the battery cell.

[0048] In this embodiment, the specific number of the second housing 200 can be set according to the capacity of the battery module, and the specific number is not limited here.

[0049] The second housing 200 has a first through hole 510 on its outer side wall. The connector 300 is located on the side of the first housing 100 and the second housing 200. The connector 300 is used to connect the first housing 100 and the second housing 200. The barrier 400 is disposed on the inner wall of the second housing 200. The battery cells are located on both sides of the barrier 400. The barrier 400 and two adjacent battery cells form a heat dissipation channel 520. The first through hole 510 is connected to the heat dissipation channel 520.

[0050] Please see Figure 3 , Figure 4 as well as Figure 5 As shown, a barrier 400 is provided on both the inner top wall and the inner bottom wall of the second housing 200. The barrier 400 is plate-shaped, and both sides of the barrier 400 abut against the surface of the battery cell. Because of the barrier 400, there is a certain gap between two adjacent battery cells. This gap is defined by the upper and lower barrier 400, the two side walls of the second housing 200, and the two battery cells. Therefore, this gap is a heat dissipation channel 520. A first through hole 510 communicating with the heat dissipation channel 520 is opened through the outer side wall of the second housing 200. Therefore, the heat generated by the battery cell can be discharged to the outside through the gas channel formed by the first through hole 510 and the heat dissipation channel 520.

[0051] Please continue reading. Figure 4 and Figure 5 As shown, first through holes 510 communicating with heat dissipation channels 520 are opened on both sides of the second housing 200. Multiple first through holes 510 are opened on each side of the second housing 200 to improve heat dissipation efficiency. Gas convection is formed by connecting two first through holes 510 with heat dissipation channels 520, which can accelerate the discharge of heat generated by the battery cell to the outside.

[0052] Please see Figure 1 , Figure 2 as well as Figure 3 As shown, the second housing 200 is provided with connectors 300 on both sides. The connectors 300 are long strips in shape. After the first housing 100, the second housing 200 and the battery cell are assembled, the connection between the first housing 100 and the second housing 200 can be achieved by installing the connectors 300 on the sides of multiple second housings 200 and two first housings 100. In other words, the connection between the first housing 100 and the second housing 200 only requires two connectors 300 to complete the assembly, which makes the assembly of the entire bracket more convenient and faster and improves production efficiency.

[0053] In one embodiment, the second housing 200 and the barrier 400 are integrally formed to prevent short circuits. In this case, both the second housing 200 and the barrier 400 can be formed of non-metallic insulating materials, and the specific material type is not limited here.

[0054] In one embodiment, the spacing between two adjacent cells is greater than the thickness of the barrier 400, thereby satisfying the expansion of the cells after the maximum expansion rate and reducing the impact of cell expansion on battery life.

[0055] For example, the shape of the first through hole 510 can be a waist-shaped groove, a circle, an ellipse, a polygon, etc. In practice, it can be designed according to needs, and there is no limitation here.

[0056] In the process of connecting the first housing 100 and the second housing 200, in order to prevent the connector 300 from blocking or closing the first through hole 510, the connector 300 is provided with a clearance hole 310, which is connected to the first through hole 510.

[0057] See Figure 2 , Figure 3 as well as Figure 6 As shown, in order to prevent the connector 300 from blocking or closing individual first through holes 510 on the side of the second housing 200, thus reducing heat dissipation efficiency, when the connector 300 is connected to the first housing 100 and the second housing 200, a clearance hole 310 can be opened on the connector 300 at the position of the first through hole 510, and the size of the clearance hole 310 is at least the same as that of the first through hole 510, so as not to block the first through hole 510. Specifically, in this embodiment, the size and shape of the clearance hole 310 can be the same as those of the first through hole 510.

[0058] For example, in order to prevent the connector 300 from blocking or closing the first through hole 510, the connector 300 can be positioned between two adjacent first through holes 510 during installation, thereby avoiding blocking the first through hole 510.

[0059] The battery cell bracket also includes a connecting structure 600, which is used to connect the first housing 100 and the second housing 200. The connecting structure 600 includes a fastener 610, a fastening groove 620, a connecting seat 630, and fasteners.

[0060] Fastener 610 is disposed on the side of the second housing 200 facing the connector 300. The connector 300 has a fastening groove 620. Fastener 610 is engaged with the fastening groove 620 for connecting the second housing 200 and the connector 300. Connecting seat 630 is disposed on the side of the first housing 100 facing the connector 300. The connector 300 has a through connecting hole 640. Fastener is disposed through the connecting hole 640 and is used for connecting the connector 300 and the first housing 100.

[0061] See Figure 4 , Figure 6 , Figure 7 as well as Figure 8 As shown, after the battery cell is assembled into the bracket formed by the first housing 100 and the second housing 200, the connector 300 is moved to both sides of the bracket. Then, the fastener 610 on the side of the second housing 200 is fastened into the fastening groove 620, thereby fixing the position of each second housing 200 and ensuring that the battery cell will not detach from the accommodating cavity formed between adjacent second housings 200. After the connector 300 and the second housing 200 are fastened together by the fastener 610 and the fastening groove 620, both ends of each connector 300 are located at the connecting seat 630 position on the two first housings 100. Then, the fastener is inserted through the connecting hole 640 into the connecting seat 630 to achieve the connection between the connector 300 and the first housing 100. At this time, the battery cell cannot detach from the accommodating cavity formed between the first housing 100 and the second housing 200. The first housing 100, the second housing 200 and the connector 300 are assembled to form a complete battery cell bracket.

[0062] For example, fasteners are components such as screws and bolts that achieve a fastening effect.

[0063] The fastener 610 includes a protruding post 611 on the side of the second housing 200 facing the connector 300. A fastening block 612 protrudes from the end of the protruding post 611. The fastening groove 620 includes a first fastening hole 621 and a second fastening hole 622 that are formed in the connector 300 and pass through it. The first fastening hole 621 communicates with the second fastening hole 622. The shape of the second fastening hole 622 is adapted to the protruding post 611.

[0064] In this embodiment, two fasteners 610 are provided on one side of each second shell 200. Correspondingly, two fastening slots 620 adapted to the fasteners 610 are provided on the connector 300 at the position of each second shell 200. The number of fasteners 610 and fastening slots 620 can also be other numbers, which are not limited here.

[0065] Please continue reading. Figure 6 and Figure 7 As shown, the fastener 610 engages with the fastening groove 620 to achieve a detachable connection between the connector 300 and the second housing 200, thereby fixing the position of each of the second housings 200. Specifically, in this embodiment, the area of ​​the first fastening hole 621 is larger than that of the second fastening hole 622. During engagement, the protrusion 611 and the fastening block 612 can simultaneously penetrate into the first fastening hole 621. At this time, the second fastening hole 622 protrudes from the side of the connector 300. Since the protrusion 611 and the fastening block 612 can enter and exit the first fastening hole 621, this state is in the unlocked state. In the locked state, the connector 300 can move upward, allowing the protrusion 611 to enter the second latching hole 622. The outer surface of the protrusion 611 contacts the inner wall of the second latching hole 622. The protrusion 611 cannot move laterally in the second latching hole 622, and the connector 300 is located between the latching block 612 and the second shell 200. That is, at this time, the latching block 612 is blocked by the connector 300 in the direction close to the second shell 200, so that the connector 300 and the latching block 612 cannot be separated, thereby achieving the fastening and completing the connection between the connector 300 and the second shell 200.

[0066] In one embodiment, in order to prevent the protrusion 611 from easily separating from the second buckle hole 622, an interference fit is made between the protrusion 611 and the second buckle hole 622.

[0067] In one embodiment, if the connector 300 does not have a clearance hole 310, in order to prevent the connector 300 from blocking the first through hole 510 on the side of the second shell 200, the fastener 610 can be positioned between two adjacent first through holes 510, so that the connector 300 will not block the first through hole 510 when it is connected to the second shell 200.

[0068] First clearance grooves 700 are provided on the frame of the first housing 100 facing the second housing 200 and on the frames of two adjacent second housings 200 that are close to each other. The first clearance grooves 700 are on the same side as the explosion-proof valve of the battery cell.

[0069] A second clearance groove 800 is provided on the frame of the first housing 100 facing the second housing 200 and on the frames of two adjacent second housings 200 that are close to each other. The second clearance groove 800 is on the same side as the terminal post of the battery cell.

[0070] See Figure 1 , Figure 2 , Figure 4 as well as Figure 8 As shown, in order to enable the bracket in this application to assemble battery cells of different thicknesses, two second clearance slots 800 are provided on the side frame of the first housing 100 and the second housing 200 that are close to each other, and on the side frame of two adjacent second housings 200 that are close to each other. The second clearance slot 800 on each side frame corresponds to the positive terminal and the negative terminal of the battery cell. The two second clearance slots 800 on the first housing 100 and the two second clearance slots 800 between the second housings 200 form a clearance space for the positive terminal and the negative terminal, and the second clearance slots 800 between two adjacent second housings 200 also form a clearance space for the positive terminal and the negative terminal. Through this clearance space, the bracket can assemble battery cells of different thicknesses.

[0071] For example, each second clearance groove 800 is a semi-circular or semi-waist-shaped groove.

[0072] In this embodiment, "same side" as mentioned above means, for example, if the positive and negative terminals and the explosion-proof valve are all located on the upper surface of the battery cell, then the second clearance groove 800 and the first positioning post 900 are also located on the top edge of the first housing 100 and the second housing 200. In this case, the second clearance groove 800, the first positioning post 900, the positive and negative terminals and the explosion-proof valve are on the same side, that is, in the same direction and orientation.

[0073] The second housing 200 has a first positioning post 900 on its surface. The first positioning post 900 is on the same side as the terminal of the battery cell. A first connecting piece 1100 is connected between adjacent battery cells. The first connecting piece 1100 is used to connect the terminal of adjacent battery cells. The first connecting piece 1100 includes a first piece body 1110. A first mounting hole 1120 is opened on the first piece body 1110. The first positioning post 900 is at least partially inserted through the first mounting hole 1120. A first positioning hole 1130 is also opened on the first piece body 1110. The first positioning hole 1130 is located at the position of the battery cell terminal.

[0074] See Figure 1 and Figure 9As shown, the positive and negative terminals of adjacent battery cells are connected in series by the first connecting piece 1100. Specifically, in order to accurately position the first connecting piece 1100, a first positioning post 900 is provided on the upper surface of the second housing 200. A first mounting hole 1120 adapted to the first positioning post 900 is opened on the first connecting piece 1100, that is, the first positioning post 900 is at least partially inserted into the first mounting hole 1120 to realize the position positioning of the first piece 1110. At this time, the position of the first positioning hole 1130 on the first piece 1110 is located at the positive and negative terminals of the adjacent battery cells. When the first piece 1110 is welded to the positive and negative terminals, the laser welding head can be positioned through the first positioning hole 1130 to make the welding smoother.

[0075] Please continue reading. Figure 9 As shown, there are two first mounting holes 1120 and two first positioning posts 900, which means two-point positioning is used to prevent the first piece 1110 from rotating. Furthermore, a bending protrusion (not shown in the figure) is provided on the first piece 1110. The bending protrusion is located between the two first mounting holes 1120. The bending protrusion can be bent to a certain extent, so that the first positioning post 900 and the first mounting hole 1120 can be more easily connected, which solves the problem of the different distances between the two first positioning posts 900 and the two first mounting holes 1120 caused by manufacturing.

[0076] A second positioning post 1000 is provided on the surface of the first housing 100. A second connecting piece 1200 is detachably installed on the first housing 100. The second connecting piece 1200 includes a second piece body 1210. A connecting post 1220 is provided on the surface of the second piece body 1210 away from the first housing 100. A second mounting hole 1230 and a second positioning hole 1240 are also provided on the second piece body 1210. The second positioning post 1000 is at least partially inserted through the second mounting hole 1230. The second positioning hole 1240 is located at the position of the cell electrode post.

[0077] The second connecting piece 1200 is detachably mounted with a third connecting piece 1300. The third connecting piece 1300 includes a third piece body 1310, on which a third mounting hole 1320 is provided. The connecting post 1220 passes through at least part of the third mounting hole 1320.

[0078] See Figure 1 , Figure 8 Figure 10 , Figure 11As shown, a second connecting piece 1200 is installed on each of the battery cells at the end of the entire bracket. The combination of the second connecting piece 1200 and the third connecting piece 1300 enables connection with a battery cell in another bracket. Specifically, to facilitate the connection between the second connecting piece 1200 and the battery cell, two second positioning posts 1000 are provided on the upper surface of the first housing 100. The second positioning posts 1000 cooperate with the two second mounting holes 1230 on the second plate 1210 to fix the second plate 1210. At this time, the second positioning hole 1240 is located at the positive or negative terminal of the battery cell, and the laser welding head is positioned through the second positioning hole 1240.

[0079] In order to connect with the battery cell in the other side bracket, a connecting post 1220 is provided on the second piece 1210 of the adjacent bracket, and the adjacent connecting posts 1220 are connected by a third connecting piece 1300. The connecting post 1220 extends into the third mounting hole 1320 of the third piece 1310 to complete the connection and installation.

[0080] In one embodiment, in order to facilitate the handling and movement of the bracket containing the battery cells, a boss 1400 or a hanging hole 1500 can be provided on the side of each first housing 100 opposite to the second housing 200. The entire bracket can be handled by manually holding the boss 1400 or by using equipment to reach into the hanging hole 1500.

[0081] In this embodiment of the application, a battery module is also provided. The battery module includes any of the above-mentioned cell supports, and each cell support holds a cell. The battery module can be composed of multiple cell supports holding cells.
