Lower box body and battery box

A battery box, comprising an upper box body and a lower box body, wherein

• the lower box body comprises a base body, a first protecting assembly and a mounting hole;
• the base body is positioned below and adjacent to the upper box body in an up-down direction, the base body comprises a bottom plate portion, a side plate portion, and eave portions, the side plate portion protrudes from the bottom plate portion in the up-down direction, and each eave portion is connected to one end of the side plate portion away from the bottom plate portion and extends toward an outside of the side plate portion;
• the first protecting assembly is provided at an outside of the base body in the up-down direction and is fixed to and overlapped with the bottom plate portion of the base body in the up-down direction, and the first protecting assembly is attached to and overlapped with the eave portions of the base body in the up-down direction;
• the lower box body further comprises a second protecting assembly provided at an outside of the first protecting assembly in the up-down direction, and the second protecting assembly is attached to and overlapped with the first protecting assembly and a corresponding portion of the base body in the up-down direction, the first protecting assembly being positioned between the base body and the second protecting assembly;
• the eave portion, the first protecting assembly and a corresponding part of the second protecting assembly are stacked together and form at least three overlapped layers in the up-down direction;
• and
• the mounting hole penetrates the at least three overlapped layers formed by the eave portion, the first protecting assembly and the second protecting assembly in the up-down direction, the mounting hole being used to fixedly mount the battery box to a vehicle via a fastener.
