[0049] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0050] On the one hand, combined with Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a module end plate, which includes: end plate body 1.

[0051] The end plate body 1 is a rectangular plate; the end plate body 1 includes a frame structure 11, which is arranged around the edge of the structural functional surface 10b, and the reinforcing structure 12 is located inside the frame structure 11; the frame structure 11 includes a top frame 111, and the two ends of the top frame 111 are respectively provided with a first positioning boss 1111, the outer side of the first positioning boss 1111 is provided with a first groove 1111a, the top surface of the first positioning boss 1111 is provided with a second groove 1111b, the first groove 1111a and the second groove 1111b are connected inside the first positioning boss 1111, and the first groove 1111a and the second groove 1111b form a hoisting structure.

[0052] In this embodiment, the module end plate has a frame structure 11 arranged on the end plate body 1. The top frame 111 of the frame structure 11 has a first positioning boss 1111 at both ends. The outer side and top surface of the first positioning boss 1111 are respectively provided with a first groove 1111a and a second groove 1111b. The first groove 1111a and the second groove 1111b are connected internally to form a hoisting structure, which can be connected to the hoisting structure from the outer side and the top. The connection operation of the hoisting structure is simple and is conducive to improving the hoisting and conveying performance of the module end plate.

[0053] In this embodiment, the hoisting structure is formed using the first groove 1111a and the second groove 1111b, which can be connected from the outer side and the top surface to meet the hoisting requirements under different assembly needs.

[0054] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the end plate body 1 includes a pressing functional surface 10a and a structural functional surface 10b, with the pressing functional surface 10a located on the inner side of the end plate body 1 and the structural functional surface 10b located on the outer side of the end plate body 1.

[0055] The border structure 11 is located on the structural functional surface 10b, and the structural functional surface 10b is also provided with a reinforcing structure 12; the border structure 11 is arranged around the edge of the structural functional surface 10b, and the reinforcing structure 12 is located inside the border structure 11.

[0056] With the above arrangement, the outer surface of the end plate body 1 serves as the structural functional surface 10b, where a frame structure 11 and a reinforcing structure 12 are arranged, while the inner surface serves as the pressure-bearing functional surface 10a, used to provide safety limits for the battery cells. The frame structure 11 and the reinforcing structure 12 are located on the structural functional surface 10b, which not only improves the structural strength of the end plate body 1 but also facilitates the hoisting and transportation of the battery module.

[0057] Among some possible implementations, refer to Figure 2 As shown, a deformation receiving groove 14 is provided on the pressure-bearing functional surface 10a. The deformation receiving groove 14 is formed by the plate surface of the end plate body 1 being recessed inward to accommodate the expansion of the battery cell.

[0058] During battery module assembly, multiple cells are clamped between two module end plates and secured by fastening components. The side of the cell in contact with the module end plate is parallel to the pressure-resistant functional surface 10a, making the deformation receiving groove 14 a hollow area. When the battery module is in use, the expansion of the cell causes the side of the cell in contact with the module end plate to deform and gradually enter the deformation receiving groove 14. That is, the deformation receiving groove 14 accommodates the expansion of the cell, thereby avoiding excessive pressure accumulation in the battery module, reducing the possibility of cell damage and explosion, and improving the safety of battery module use.

[0059] In some possible implementations, the end plate body 1 is a plastic structural component, which has a lower cost and helps to reduce the overall weight of the battery module, thereby increasing the energy density of the battery module. It also has reduced rigidity and a certain degree of resilience, which can restore the original shape after elastic deformation. Therefore, it can effectively absorb the expansion of the battery module, effectively improving the service life of the battery module. In addition, it also has good insulation performance, which can prevent the battery module from causing accidental short circuits or electric shocks during operation, thus improving the safety performance of the battery module.

[0060] Combination Figure 1 and Figure 3 As shown, in some embodiments, the first positioning boss 1111 is provided with a first positioning fixing hole 1111d arranged in a vertical direction, and the first groove 1111a and the second groove 1111b are respectively located on the side of the first positioning fixing hole 1111d facing the other end of the top frame 111.

[0061] With the above arrangement, the module end plate can be positioned and fixed by inserting the positioning component on the assembly equipment during battery module assembly using the two first positioning and fixing holes 1111d on the two first positioning bosses 1111. The first groove 1111a and the second groove 1111b are arranged on the first positioning bosses 1111 along with the first positioning and fixing holes 1111d. The hoisting structure and the positioning assembly structure share space, resulting in high space utilization and reducing the difficulty of arranging the hoisting structure.

[0062] Combination Figure 1 and Figure 3 As shown, in some embodiments, the top frame 111 is also provided with two terminal mounting slots 1112, each terminal mounting slot 1112 being located on one side of a first positioning boss 1111 facing the other end of the top frame 111.

[0063] The first positioning boss 1111 is also provided with a third groove 1111c on the side facing the terminal mounting groove 1112. The third groove 1111c is connected to the first groove 1111a and the second groove 1111b inside the first positioning boss 1111.

[0064] With the above arrangement, the module end plate can use the terminal mounting slot 1112 to accommodate the battery terminals and several busbars, thereby reducing the possibility of breakage at the connection between the battery terminals and the integrated busbars.

[0065] A third groove 1111c is arranged on the side of the first positioning boss 1111 facing the terminal mounting groove 1112. The third groove 1111c communicates with the first groove 1111a and the second groove 1111b, which can further expand the volume of the hoisting structure and further improve the ease of operation of the hoisting structure.

[0066] For example, the electrode terminal typically includes a terminal base and a terminal cover, with the connector of the integrated busbar clamped between the terminal base and the terminal cover. The space provided by the lug can be used to add other reinforcing structures or components such as clamps and reinforcing welds to the terminal base and the terminal cover, thereby improving the connection strength between the electrode terminal and the integrated busbar.

[0067] Combination Figure 1 and Figure 3 As shown, in some embodiments, a baffle portion 1112a is provided on the inner side of the terminal mounting groove 1112, and the outer side of the terminal mounting groove 1112 is open.

[0068] The top frame 111 has a fourth groove 1111e arranged vertically. Part of the fourth groove 1111e is located in the terminal mounting groove 1112, and another part is located in the first positioning boss 1111. It communicates with the first groove 1111a, the second groove 1111b and the third groove 1111c inside the first positioning boss 1111.

[0069] With the above arrangement, a fourth groove 1111e is arranged on the top frame 111. A part of the fourth groove 1111e is located in the terminal mounting groove 1112, and another part is located in the first positioning boss 1111. This can further expand the volume of the hoisting structure and further improve the ease of operation of the hoisting structure.

[0070] The hoisting structure in this embodiment is formed by the first groove 1111a, the second groove 1111b, the third groove 1111c, and the fourth groove 1111e communicating together. It has openings facing outward, top, and inward. Hoisting hooks, lifting rods, and other lifting devices can be connected to the hoisting structure from different directions, thus making the connection of the module end plate more convenient.

[0071] Combination Figure 1 and Figure 4 As shown, in some embodiments, the top frame 111 is further provided with a second positioning boss 1113, which is located in the middle of the top frame 111 and has a second positioning fixing hole 1113a arranged in the vertical direction.

[0072] To accommodate the increased size of the module end plate, a second positioning boss 1113 is arranged in the middle of the top frame 111, and a second positioning fixing hole 1113a is arranged on the second positioning boss 1113 for positioning and fixing the module end plate during battery module assembly.

[0073] In some possible implementations, the top surface of the second positioning boss 1113 is also provided with a wire harness fixing slot 1113b for fixing the wire harness of the battery module.

[0074] Combination Figure 1 As shown, in some embodiments, the border structure 11 includes two side borders 112, which are located on the sides of the structural functional surface 10b.

[0075] The top of each side frame 112 is connected to a first positioning boss 1111. The side frame 112 is provided with at least one limiting groove 1121, which is recessed along the outer surface of the side frame 112.

[0076] In this embodiment, in order to improve the limiting effect of the module end plate on the fixed steel strip, at least one limiting groove 1121 is arranged on the side frame 112. The fixed steel strip is snapped and fixed in the limiting groove 1121. When the fixed steel strip is displaced due to the battery expansion force or shaking, the existence of the limiting groove 1121 can provide a resisting force to counteract the displacement of the fixed steel strip, thereby limiting the fixed steel strip. This helps to reduce the possibility of the fixed steel strip shifting and sliding during the transportation and use of the battery module, improves the stability of the fit between the fixed steel strip and the module end plate, and further improves the stability of the connection between the battery module and the end plate.

[0077] Combination Figure 1 and Figure 3 As shown, in some embodiments, the first positioning boss 1111 is provided with a first positioning fixing hole 1111d arranged in the vertical direction; the first positioning fixing hole 1111d passes through the first positioning boss 1111 and the corresponding side frame 112 in the vertical direction.

[0078] With the above arrangement, the first positioning fixing hole 1111d passes through the first positioning boss 1111 and the side frame 112 in the vertical direction, so that the positioning structure inserted in the first positioning fixing hole 1111d can provide a uniform upper and lower limiting force on the entire module end plate.

[0079] Combination Figure 1 and Figure 4 As shown, in some embodiments, the top frame 111 is further provided with a second positioning boss 1113, and the frame structure 11 includes two side frames 112, with at least one limiting groove 1121 on the side frame 112.

[0080] The frame structure 11 also includes a middle support frame 113, which is connected to the second positioning boss 1113; the middle support frame 113 is provided with at least one support surface 1131, which is aligned with the limiting groove 1121.

[0081] With the above arrangement, when the lateral dimension of the module end plate is large, in addition to the limiting grooves 1121 on the side frame 112 of the two edges being able to limit and fix the fixing strip, the supporting surface 1131 on the middle support frame 113 can also be used to support the middle area of ​​the fixing strip.

[0082] Furthermore, at least one support surface 1131 on the middle support frame 113 can form a large structural area in the middle of the module end plate, which can further improve the structural strength of the module end plate.

[0083] Combination Figure 1 and Figure 4As shown, in some embodiments, the reinforcing structure 12 includes a plurality of connecting columns 121, a plurality of top columns 122, and reinforcing ribs 123. The plurality of connecting columns 121 and the plurality of top columns 122 are respectively distributed inside the frame structure 11, and any two adjacent connecting columns 121 and the plurality of top columns 122 are connected by reinforcing ribs 123.

[0084] Among some possible implementations, refer to Figure 1 As shown, the reinforcing rib 123 includes several transverse reinforcing ribs, several longitudinal reinforcing ribs and several diagonal reinforcing ribs. The transverse and longitudinal reinforcing ribs are arranged alternately to form a rectangular grid structure. The diagonal reinforcing ribs are located in the grid at the four corners of the end plate body 1 to reinforce the four corners of the end plate body 1.

[0085] On the other hand, this embodiment provides a battery module, which includes the module end plate of this application.

[0086] The battery module of this embodiment uses the module end plate of this application and has all the beneficial technical effects of all embodiments herein.

[0087] In some possible implementations, the battery module also includes multiple battery cells and a fixing steel strip. The module end plates are located at both ends of the multiple battery cells along the length direction, and the steel strip is sleeved on the outer periphery of the two module end plates and the multiple battery cells to fix the multiple battery cells between the two module end plates.

[0088] When it is necessary to move the battery modules into the battery pack housing, simply install lifting hooks, booms, and other lifting devices within the lifting structure, and then connect the lifting equipment to the lifting devices using ropes and other connectors. The battery modules can then be lifted and moved into the housing using the lifting equipment. In this embodiment, the lifting structure is formed using the first groove 1111a and the second groove 1111b, allowing connection from the outer side and top surface. This meets the lifting requirements under different assembly needs. For example, when using top-side connection, the lifting devices do not occupy space on both sides of the battery modules, which helps to reduce the gap between each battery module, thereby reducing the volume of the battery pack and effectively improving the space utilization rate within the battery pack housing, ultimately increasing the battery pack capacity.
