FIG7 is a schematic structural diagram of a blocking member according to another embodiment of the present disclosure  FIG8 is a schematic structural diagram of a blocking member according to yet another embodiment of the present disclosure 
FIG7 shows a schematic structural diagram of a blocking member 50 according to another embodiment of the present disclosure. The orthographic projection of the adapter portion 52 of the blocking member 50 on the plate-like structure in the above embodiments is not limited to a square. As shown in FIG7, in an example, the orthographic projection of the adapter portion 52 on the plate-like structure may also be a circle. Of course, it may be an ellipse, a lumbar circle, or other irregular shapes, etc., as long as the requirements of the connection with the second end plate 40 and the plate-like structure can be satisfied. The position and size of the open notch 513 can also be adjusted according to the installation requirements.  Referring to FIG8, a schematic structural diagram of a blocking member 50 according to yet another embodiment of the present disclosure is shown. The blocking member 50 in each of the above embodiments includes two adapter portions 52. It can be understood that that is an alternative embodiment, but is not limited to the foregoing structures. As shown in FIG8, the blocking member 50 may include only one adapter portion 52, and the one adapter portion 52 is preferably connected at a center position or an area close to the center position of the abutment portion 51. In order to ensure the strength of the connection with the second end plate 40, the extending length of the adapter portion 52 in the first direction X may be longer in the embodiment. Of course, in some embodiments, there may be a plurality of adapter portions 52 as needed, e.g. three or more adapter portions. The plurality of adapter portions 52 are spaced apart from each other on the abutment portion 51 in the first direction X. The interval can be set according to the size of the battery module, etc., which will not be described here.
