BATTERY, DRIVE DEVICE, AND VEHICLE

WIPO Patent Application WO/2021/051990

A1

The present application relates to a vehicle, a battery, and a drive device. The battery comprises: a first casing member; a second casing member connected to the first casing member; a battery unit accommodated in the first casing member and the second casing member; and a sealing gasket located between the first casing member and the second casing member to sealingly connect the first casing member and the second casing member, wherein the first casing member and/or the second casing member is provided with a first protruding portion, a side wall of the sealing gasket is provided with a gap portion, the gap portion passes through the sealing gasket in a thickness direction of the sealing gasket, and the first protruding portion extends into the gap portion, such that the first protruding portion fits with the gap portion. The fit between of the first protruding portion and the gap portion can limit dislocation of the sealing gasket by means of the first casing member and/or the second casing member, thereby enhancing the seal provided by the sealing gasket to a cavity. In addition, providing the sealing gasket with the gap portion ensures seal performance while reducing the size of the sealing gasket, thereby reducing the cost and weight of a battery and improving energy density.
