[0021] In the sixth technical solution and related embodiments, the provision of the first reinforcing rib increases the strength of the top cover and avoids deformation of the top cover.

[0022] In the seventh technical solution and related embodiments, abutment portions suitable for abutting the top wall are provided at both ends of the first reinforcing rib along the X-axis direction, so that the top cover forms a multi-point support structure in the Y-axis direction, further preventing the top cover from collapsing and deforming.

[0023] In the eighth technical solution and related embodiments, the provision of the second reinforcing rib further increases the strength of the top cover and simultaneously strengthens the strength of the first reinforcing rib, thereby ensuring that the abutment between the abutting portion and the top wall is stable and reliable, further providing a guarantee for the anti-deformation of the top cover.

In the present embodiment, each battery module 20 is provided with a top wall 23 facing away from the base 10 .

[0046] The support member 30 is suitable for being plugged into the plug-in channel 01 and extending out of the end plate 21, and at least part of it corresponds to the middle of the battery assembly; in this embodiment, the number of the support members 30 is at least two, and each support member 30 is plugged into the plug-in channel 01 of the end plate 21 in the middle of the battery assembly.

[0048] The top cover 40 is fixedly connected to the bottom bracket 10 to form a receiving cavity for accommodating the battery assembly, which is suitable for being supported by the support member 30. Figure 1 The top cover 40 is an open box-shaped body with a flange 44. The flange 44 is suitable for being locked to the connecting edge 11 to form a receiving cavity suitable for accommodating the battery assembly. The opening of the top cover 40 faces downward. Figure 6 The top of the top cover 40 forms an upper wall 41, and the two ends of the top cover 40 along the Y-axis direction are respectively provided with a front wall 42 and a rear wall 43, and the flange 44 is suitable for being locked on the connecting edge 11 to form a receiving cavity suitable for accommodating the battery assembly. The structure is simple and practical.

[0049] Still see Figure 6 A plurality of first reinforcing ribs 411 extending along the X-axis direction are arranged in the top cover 40 at intervals along the Y-axis direction. Abutment portions 4111 suitable for abutting against the top wall 23 are provided at both ends of the first reinforcing rib 411 along the X-axis direction. Figure 6 and Figure 8 In the figure, the first reinforcing rib 411 is a U-shaped structure with its opening downward. A plurality of second reinforcing ribs 412 extending along the Y-axis direction are arranged in the top cover 40 along the X-axis direction, and the second reinforcing ribs 412 and the first reinforcing ribs 411 are staggered to form a grid structure. A plurality of reinforcing protrusions 413 extending along the X-axis direction are arranged in the top cover 40 at intervals along the Y-axis direction, and the first reinforcing rib 411 is embedded in the reinforcing protrusion 413 and extends out of the reinforcing protrusion 413. The reinforcing protrusion 413 is formed by stamping the upper wall 41, and the length of the reinforcing protrusion 413 along the Y-axis direction is greater than the length of the first reinforcing rib 411 along the Y-axis direction, and the length of the reinforcing protrusion 413 along the Z-axis direction is less than the length of the first reinforcing rib 411 along the Z-axis direction, and the first reinforcing rib 411 and the second reinforcing rib 412 are both formed on the upper wall 41. A window is formed on the front wall 42 , and a plurality of third reinforcing ribs 431 are protruded from the rear wall 43 and are arranged at intervals along the X-axis direction and extend along the Z-axis direction. In actual applications, the third reinforcing ribs 431 are also formed by stamping.

[0050] In the present embodiment, since the battery assembly includes two battery modules 20 arranged along the Y-axis direction, overall, the top cover 40 has a longer length along the Y-axis direction, and the middle part of the top cover 40 is prone to collapse; in the present embodiment, the support member 30 is inserted into the insertion channel 01 of the end plate 21 and extends out of the end plate 21, and the support member 30 at least partially corresponds to the middle part of the battery assembly, so after the top cover 40 is fixed to the bottom bracket 10, the middle part of the top cover 40 can be supported by the support member 30, thereby avoiding the collapse of the middle part of the top cover 40. The above-mentioned arrangement makes full use of the structure of the end plate 21 itself, and it is only necessary to add the support member 30 on the basis of the original energy storage module to avoid the collapse of the middle part of the top cover 40. Therefore, the structure is simple and clever, and compared with other solutions, such as improving the material of the top cover 40, the cost is lower.

[0051] In the present embodiment, since the end of the top cover 40 is locked with the bottom support 10, the end of the top cover 40 is not easy to collapse, and each support member 30 is inserted into the insertion channel 01 of the end plate 21 in the middle of the battery assembly, thereby reducing the unnecessary cost of setting the support member 30 in the insertion channel 01 of the end plate 21 at the end of the battery assembly. The setting of multiple support members 30 ensures multi-point support in the middle of the top cover 40.

[0052] In this embodiment, the support member 30 is provided with a plug-in portion 31 and an elastic support portion 32 fixed to each other. The elastic support portion 32 is suitable for extending out of the plug-in channel 01 and supporting the top cover 40. The elastic support portion 32 can provide a buffer for the top cover 40 and can also avoid the unbalanced support caused by the height inconsistency of each elastic support portion 32. The elastic buckle 311 is engaged with the engaging hole 221 so that the support member 30 is plugged into the plug-in channel 01. The structure is simple and the assembly and disassembly are convenient. The supporting surfaces 321 are located in the same plane, which ensures the balance of the multi-point support of each support member 30.

[0053] In this embodiment, the provision of the first reinforcing rib 411 increases the strength of the top cover 40 and prevents the top cover 40 from being deformed. The first reinforcing rib 411 is provided with abutting portions 4111 suitable for abutting the top wall 23 at both ends along the X-axis direction, so that the top cover 40 forms a multi-point support structure in the Y-axis direction, further preventing the top cover 40 from collapsing and deforming. The provision of the second reinforcing rib 412 further increases the strength of the top cover 40, and simultaneously strengthens the strength of the first reinforcing rib 411, thereby ensuring that the abutting portion 4111 is in stable and reliable contact with the top wall 23, further providing a guarantee for the anti-deformation of the top cover 40. The provision of the reinforcing protrusion 413, on the one hand, further increases the strength of the top cover 40, and on the other hand, makes the first reinforcing rib 411 less likely to be deformed, bent or broken, thereby ensuring that the abutting portion 4111 is in stable contact with the top wall 23, further providing a guarantee for the anti-deformation of the top cover 40. The thick wall of the top cover 40 is provided with a third reinforcing rib 431 to strengthen the strength of the rear wall 43 of the top cover 40 , and the front wall 42 of the top cover 40 can be used to form a window or the like.
