Battery devices and electrical appliances

Abstract

This application discloses a battery device and an electrical device. The battery device includes a housing and multiple battery cells. The housing includes a main body, a bottom guard plate, and a protective structure. An accommodating cavity is provided inside the main body. The bottom guard plate is located on one side of the main body along a first direction. The protective structure is located on the side of the bottom guard plate facing the main body. The protective structure includes a first protective member and a second protective member. The first protective member is fixed to the bottom guard plate, and the second protective member is fixed to the main body. The first protective member includes a first inclined surface, and the second protective member includes a first wall and a second inclined surface contacting the first inclined surface. The first wall is located at the end of the second inclined surface opposite to the bottom guard plate. The orthographic projection of the first wall along the first direction at least partially overlaps with the orthographic projection of the first inclined surface along the first direction. Multiple battery cells are disposed within the accommodating cavity. This application can improve the impact resistance of the bottom of the battery device, reduce the risk of damage to the bottom of the battery device during impact, and thus improve the reliability of the battery device.
