Description

Battery pack and electricity utilization device Technical Field The application relates to the technical field of batteries, in particular to a battery pack and an electric device. Background The battery pack is an indispensable component in the electric power equipment, and is usually configured by installing a battery module in a case to supply power to an electric device. The box is the panel beating box generally, and the panel beating box can use these two kinds of methods of welding and spiro union to connect generally, and the material of roof beam body and box is generally different, adopts the design of spiro union between the roof beam body of different materials and the metal plate body generally. After the battery module is used for a period of time, certain expansion can be generated, and the expanded battery can give certain pressure to the beam body. The stability of current roof beam body is relatively poor, and the roof beam body is pressed and is warp, can let battery module continue to expand on the one hand, and the roof beam body of on the other hand warp can extrude other battery modules, leads to battery module to warp seriously, influences the performance of battery package. Disclosure of utility model The embodiment of the application provides a battery pack and an electric device, which can improve the stability of a beam body and at least partially solve the technical problems. In order to achieve the above object, according to a first aspect of the present application, there is provided a battery pack having a first direction, a second direction, and a third direction intersecting with each other, the battery pack comprising: a case; The beam body is arranged in the box body along the first direction, is provided with two end parts which are arranged opposite to each other along the first direction, and is connected with the box body; The beam body fixing structure comprises at least two first brackets and second brackets, wherein the first brackets are arranged near the end parts, the first brackets are respectively arranged on two sides of the beam body in the second direction, the first brackets are connected with the beam body and the box body, and the second brackets are positioned on one side of the beam body in the first direction and are connected with the first brackets on two sides of the beam body.
