Of course, the box 21 formed by the first part 211 and the second part 212 can have various shapes, such as a cylinder, a cuboid, etc.

[0055] In the battery 20, the battery cells 22 can be multiple, and the multiple battery cells 22 can be connected in series, in parallel, or in a mixed connection. The mixed connection means that the multiple battery cells 22 are connected in series and in parallel.

The actual situation can be determined, and the embodiment of the present application does not limit this. In this way, the strength of the plate body 101 can be effectively improved, and damage caused by collision can be avoided.

[0088] According to some embodiments of the present application, as shown in Figure 5 or Figure 6 The plate body 101 is provided with a through hole 1011 in the thickness direction. In this way, the bolt can be conveniently connected with other components by penetrating the plate body 101.

[0089] According to some embodiments of the present application, the battery device further comprises a second sealing member (not indicated in the figure) arranged on the inner ring of the through hole 1011.

[0090] The second sealing member in the embodiment can be a rubber sealing ring, a polytetrafluoroethylene sealing ring, etc., which is not limited here.

[0091] By arranging the second sealing member on the inner ring of the through hole 1011, the sealing property between the bolt and the plate body 101 can be ensured when the bolt penetrates the corresponding through hole 1011.

[0092] According to some embodiments of the present application, the side plate 102 is provided with a flange at the periphery of the side away from the plate body 101, which is in close contact with the side of the second part 212. In this way, the side plate 102 is connected together with the side of the second part 212 through the flange.

[0093] The present application also provides a battery device as claimed in any one of the preceding embodiments.

[0094] The specific structure of the battery device in the present embodiment is referred to the above embodiments. Since all the technical solutions of the above embodiments are adopted in the battery device, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, which will not be repeated here.

[0095] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that: they can still modify the technical solutions recorded in the above embodiments, or make equivalent replacement to some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application. Especially, as long as there is no structural conflict, each technical feature mentioned in each embodiment can be combined in any way. The present application is not limited to the specific embodiments disclosed in the text, but includes all the technical solutions falling within the scope of the claims.
