[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] As described in the background art, the battery module of the related technology includes a frame and multiple cylindrical batteries. The frame includes a base plate, and multiple sets of cylindrical batteries are arranged along the height direction of the frame. When it is necessary to fix the bottom multiple cylindrical batteries in the frame, an adhesive is needed to bond the bottom multiple cylindrical batteries, so that the multiple cylindrical batteries are fixed in the frame.

[0031] However, by using adhesives to directly bond multiple cylindrical batteries to the base plate, the fixing strength of the bottom layer of cylindrical batteries is reduced.

[0032] This application provides a battery module and an automobile. By employing a mounting strip, the distance between the multiple batteries in the bottommost cell layer and the base plate is increased. By fixing the multiple batteries in the bottommost cell layer to the mounting strip and the base plate with adhesive, the thickness of the adhesive is increased, thereby improving the fixing strength between the multiple batteries in the bottommost cell layer and the base plate. By employing a serpentine plate, multiple batteries in adjacent cell layers can be fixed in the first and second slots respectively. The serpentine plate is fixed to the base plate of the frame by a fixing plate, allowing multiple batteries to be indirectly fixed to the base plate, thereby further improving the fixing strength of multiple batteries within the frame. By engaging the connector of the copper plate with the mounting port on the serpentine plate, the copper plate can be fixed to the serpentine plate, improving the fixing strength of the copper busbar within the frame.

[0033] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0034] Referring to Figures 1 to 3, a battery module includes a frame 100, a cell unit 200, and a mounting component 300. The frame 100 includes a base plate 110. Multiple sets of cell units 200 are arranged along the width direction of the frame 100. The mounting component 300 is disposed between the lowermost part of the cell unit 200 and the base plate 110 to form an adhesive space 310 between the cell unit 200, the mounting component 300, and the base plate 110. The adhesive space 310 is configured to simultaneously fix the cell unit 200, the mounting component 300, and the base plate 110 by means of an adhesive.

[0035] By adopting the above technical solution, by setting the mounting part 300 and placing the bottom part of the cell unit 200 on the mounting part 300, the distance between the bottom part of the cell unit 200 and the base plate 110 can be increased. When adhesive is used in the bonding space 310, the increased distance between the bottom part of the cell unit 200 and the base plate 110 increases the thickness of the adhesive, thereby improving the fixing strength of the cell unit 200. Furthermore, by placing the cell unit 200 on the mounting part 300, when adhesive is used for bonding, the mounting part 300 can indirectly fix the cell unit 200 together, so that the cell unit 200, the mounting part 300 and the base plate 110 are fixed at the same time, further improving the fixing strength of multiple batteries 211.

[0036] Referring to Figures 3 to 7, each group of battery cell units 200 includes multiple battery cell layers 210, and each group of battery cell layers 210 includes multiple batteries 211. The mounting component 300 includes at least two mounting strips 320. The mounting strips 320 are disposed between the multiple batteries 211 of the bottommost battery cell layer 210 and the base plate 110. The mounting strips 320 are disposed along the length direction of the multiple batteries 211 of the battery cell layer 210.

[0037] In this embodiment, four groups of cell units 200 are provided, and each group of cell units 200 includes two cell layers 210, and each cell layer 210 includes thirteen batteries 211; the batteries 211 of the upper cell layer 210 and the batteries 211 of the lower cell layer 210 are arranged alternately; in other embodiments, the number of cell units 200, cell layers 210 and batteries 211 can be adaptively adjusted as needed.

[0038] In this embodiment, four sets of mounting members 300 are provided, and the four sets of mounting members 300 correspond one-to-one with the four sets of battery cell units 200. Each mounting member 300 includes two mounting strips 320, which are located on both sides of the same battery 211. The cross-section of the mounting strips 320 is rectangular, and the rectangular mounting strips 320 form two bonding spaces 310 between the battery 211 and the base plate 110, and the two mounting strips 320 form four bonding spaces 310 between the battery 211 and the base plate 110. The mounting strips 320 are made of insulating material. In other embodiments, the number and shape of the mounting strips 320 can be adjusted as needed, for example, each mounting member 300 can include four mounting strips 320, or the cross-section of the mounting strips 320 can be set as an isosceles trapezoid.

[0039] By adopting the above technical solution, the installation strip 320 has a simple structure, is easy to manufacture, and improves the production efficiency of multiple installation strips 320. By using at least two installation strips 320, each installation strip 320 can form an adhesive space 310 between its two sides and multiple batteries 211 and the base plate 110. By using adhesive in each adhesive space 310, the number of adhesive points between multiple batteries 211 and the installation strip 320 and the base plate 110 is increased, thereby further improving the fixing strength of multiple batteries 211. By setting the installation strip 320 along the length direction of multiple batteries 211 in the cell layer 210, multiple batteries 211 can be fixed simultaneously on multiple installation strips 320 and the base plate 110, thereby further improving the fixing strength of multiple batteries 211.

[0040] Referring to Figures 3 to 7, the battery module also includes a connector 400. A connector 400 is provided between adjacent cell layers 210, and multiple batteries 211 of adjacent cell layers 210 are respectively arranged on both sides of the connector 400.

[0041] In this embodiment, each group of battery cell units 200 includes two battery cell layers 210, and four connectors 400 are provided, with each of the four connectors 400 corresponding to one of the four groups of battery cell units 200.

[0042] By adopting the above technical solution, by setting the connector 400 between adjacent cell layers 210, it is convenient to fix multiple cell layers 210 when multiple cell layers 210 are set along the height direction of the frame 100, thereby improving the fixing strength of the multiple cell layers 210; and by separating adjacent cell layers 210 by the connector 400, it is prevented that the batteries 211 of adjacent cell layers 210 will affect each other during operation.

[0043] Referring to Figures 3 to 7, the battery 211 is a cylindrical battery, and the connector 400 includes a serpentine plate 410. One side of the serpentine plate 410 has a plurality of first grooves 420, and the other side of the serpentine plate 410 has a plurality of second grooves 430. The first grooves 420 and the second grooves 430 are configured to cooperate with the cylindrical battery.

[0044] In this embodiment, the axis of the cylindrical battery is perpendicular to the length direction of the mounting strip 320; thirteen first grooves 420 are provided, each corresponding to one of the thirteen batteries 211 in the upper cell layer 210; thirteen second grooves 430 are provided, each corresponding to one of the thirteen batteries 211 in the lower cell layer 210; the first grooves 420 and the second grooves 430 are arc-shaped, and the arc-shaped first grooves 420 and second grooves 430 are configured to cooperate with the cylindrical battery; the battery 211 is fixed in the first grooves 420 and second grooves 430 by adhesive; in other embodiments, the battery 211 can be replaced with a cuboid, and the first grooves 420 and second grooves 430 can be configured to cooperate with the cuboid battery 211.

[0045] By adopting the above technical solution, the cylindrical battery configuration provides better thermal diffusion, higher production consistency, and enhanced safety. The use of the serpentine plate 410, the first groove 420, and the second groove 430 increases the contact area between the battery 211 and the serpentine plate 410 when the battery 211 is fixed within them, thus improving the fixing strength between them. Furthermore, by coordinating the first groove 420 and the second groove 430 with the cylindrical battery, the space occupied by adjacent cell layers 210 and the serpentine plate 410 is reduced, thereby reducing the overall space occupied by the battery module and the installation space required for mounting the battery module on the vehicle body.

[0046] Referring to Figures 3 to 7, in this embodiment, the cylindrical battery has a positive electrode 212 and a negative electrode 213, which are disposed at the same end of the cylindrical battery. An explosion-proof valve 214 is provided at the end where the positive electrode 212 and the negative electrode 213 of the cylindrical battery are located. By disposing the positive electrode 212 and the negative electrode 213 of the cylindrical battery at the same end of the battery 211, it is convenient to electrically connect multiple batteries 211.

[0047] Referring to Figures 3 to 7, the serpentine plate 410 has a refrigerant channel inside, and the serpentine plate 410 has a liquid inlet and a liquid outlet. The liquid inlet is connected to one end of the refrigerant channel, and the liquid outlet is connected to the other end of the refrigerant channel.

[0048] In this embodiment, the liquid inlet and liquid outlet are located at both ends of the serpentine plate 410, or the liquid inlet and liquid outlet can be located at the same end of the serpentine plate 410. The refrigerant channels inside the serpentine plate 410 are distributed in a serpentine pattern, thereby increasing the cooling area of ​​the serpentine plate 410 and improving the cooling efficiency of the serpentine plate 410 for the battery 211.

[0049] By adopting the above technical solution, and by setting up a refrigerant channel, an inlet end, and an outlet end, the refrigerant is introduced from the inlet end, allowing it to flow within the refrigerant channel. This enables the serpentine plate 410 to cool the multiple batteries 211 in the first tank 420 and the second tank 430 through the refrigerant in the channel. Since the first tank 420 and the second tank 430 are in conjunction with the cylindrical batteries, the contact area between the serpentine plate 410 and the batteries 211 is increased, indirectly improving the cooling efficiency of the serpentine plate 410 for the multiple batteries 211. The refrigerant after cooling the batteries 211 can be discharged along the outlet end, facilitating the delivery of new refrigerant to the serpentine plate 410. Cooling the batteries 211 helps reduce the capacity decay of the batteries 211 and extends their service life.

[0050] Referring to Figures 3 to 7, the battery module also includes a fixing member 500. Both ends of the connector 400 are provided with fixing members 500, and the fixing members 500 are configured to fix the connector 400 to the base plate 110. In this embodiment, the fixing members 500 are provided at both ends of the serpentine plate 410.

[0051] By adopting the above technical solution and by setting the fastener 500, both ends of the serpentine plate 410 can be fixed to the base plate 110. When the battery 211 is fixed to the serpentine plate 410, the multi-layer battery cell layer 210, except for the bottommost battery cell layer 210, can be indirectly fixed to the base plate 110, thereby further improving the fixing strength of the multi-layer battery cell layer 210. By setting the fastener 500 at both ends of the serpentine plate 410, the fixing strength between the serpentine plate 410 and the base plate 110 is improved, thereby further improving the fixing strength of the multiple batteries 211 within the frame 100.

[0052] Referring to Figures 3 to 7, the fastener 500 includes a fixing plate 510, one side of which is connected to the connector 400, and the other side is disposed on the base plate 110.

[0053] In this embodiment, the fixing plate 510 and the serpentine plate 410 are integrally formed. The width of the fixing plate 510 is smaller than the width of the serpentine plate 410. The fixing plate 510 is L-shaped. The L-shaped fixing plate 510 includes a first plate body 511 and a second plate body 512. The first plate body 511 and the second plate body 512 are integrally formed. One side of the first plate body 511 is connected to the serpentine plate 410, and the other side of the first plate body 511 is connected to the second plate body 512. The second plate body 512 abuts against the base plate 110 and is fixed to the base plate 110 by bolts. In other embodiments, the second plate body 512 can also be fixed to the base plate 110 by welding. The shape of the fixing plate 510 can be adjusted as needed.

[0054] By adopting the above technical solution and by setting the fixing plate 510, the fixing plate 510 has a simple structure and is easy to manufacture, which improves the manufacturing efficiency of the serpentine plate 410 and the fixing plate 510; by fixing the fixing plate 510 to the serpentine plate 410 and the base plate 110, the fixing strength of the serpentine plate 410 is improved.

[0055] Referring to Figures 3 to 7, in this embodiment, a waist-shaped hole 513 is provided on the second plate 512 at the position where the bolt passes through, and the shank of the bolt can move within the waist-shaped hole 513, thereby facilitating the adjustment of the installation position of the serpentine plate 410.

[0056] Referring to Figures 3 to 7, the battery module also includes an assembly 600, which is disposed on the connector 400 and is configured as a copper busbar for fixing the battery module.

[0057] In this embodiment, each serpentine plate 410 is provided with two fittings 600. The two fittings 600 are provided on the surface of the serpentine plate 410 away from the base plate 110. The two fittings 600 are located near the fixing plate 510 and are respectively provided on both sides of the serpentine plate 410.

[0058] By adopting the above technical solution and using the assembly 600, the assembly 600 can fix the copper busbar of the battery module. Since the serpentine plate 410 is fixed to the base plate 110 by the fixing plate 510, the copper busbar can be fixed to the base plate 110 by the serpentine plate 410 and the fixing plate 510, thereby improving the fixing strength of the copper busbar. Furthermore, when fixing the copper plate, by utilizing the space at the end of the serpentine plate 410, the space occupied between the copper plate and the serpentine plate 410 is reduced, thereby further reducing the installation space of the battery module.

[0059] Referring to Figures 3 to 7, the assembly 600 includes a mounting plate 610, which has a plurality of mounting ports 611 configured to engage or disengage with a connector of a copper busbar to fix or detach the mounting plate 610 and the copper busbar.

[0060] In this embodiment, the mounting plate 610 is fixed to the serpentine plate 410 by welding. The mounting plate 610 includes a first connecting plate 612, a second connecting plate 613, and a third connecting plate 614. The first connecting plate 612 abuts against the serpentine plate 410 and is fixed to the serpentine plate 410. The second connecting plate 613 is perpendicular to the first connecting plate 612, and one side of the second connecting plate 613 is connected to one side of the first connecting plate 612. The third connecting plate 614 is parallel to the first connecting plate 612, and one side of the third connecting plate 614 is connected to... The second connecting plate 613 is connected to the edge away from the first connecting plate 612. The third connecting plate 614 and the serpentine plate 410 are spaced apart. The first connecting plate 612, the second connecting plate 613 and the third connecting plate 614 are integrally formed. The mounting port 611 is provided on the third connecting plate 614. Each third connecting plate 614 is provided with three mounting ports 611. The three mounting ports 611 are arranged parallel to each other and are rectangular. In other embodiments, the mounting plate 610 and the serpentine plate 410 can also be integrally formed.

[0063] The specific structure of the battery module has been described in detail in the above embodiments, and will not be repeated here.

[0064] The automobile provided in this application embodiment, by setting a battery module, and the battery module adopting the setting of mounting strip 320, increases the distance between the multiple batteries 211 of the bottom cell layer 210 and the base plate 110. By fixing the multiple batteries 211 of the bottom cell layer 210 to the mounting strip 320 and the base plate 110 with adhesive, the thickness of the adhesive is increased, thereby improving the fixing strength between the multiple batteries 211 of the bottom cell layer 210 and the base plate 110; by adopting the setting of serpentine plate 410, the adjacent cell layers 210 are... Multiple batteries 211 of the 10 can be fixed in the first groove 420 and the second groove 430 respectively.
