AI Technical Summary
Technical Problem
The connection method between the expansion beam and the housing in existing battery devices is prone to deformation, which affects the reliability and load-bearing capacity of the battery device.
Method used
By setting up the connection structure between the installation beam and the box body and adjusting the connection method between the installation beam and the box body, the load-bearing capacity of the installation beam and expansion beam is enhanced, and the structural strength is improved.
Benefits of technology
This improved the reliability and load-bearing capacity of the battery pack and reduced the possibility of deformation of the expansion beam and housing.

Abstract
This application discloses a battery device and an electrical appliance. The battery device includes battery cells and a housing. The housing includes a wall, a mounting beam, and an expansion beam. The wall encloses a receiving cavity. The mounting beam and the expansion beam both extend along a first direction and are disposed within the receiving cavity. The mounting beam connects the expansion beam and the wall. Multiple battery cells are disposed within the receiving cavity, and the expansion beam abuts against the battery cells. The wall includes a side wall and a bottom wall. The mounting beam includes a first edge and a second edge disposed opposite each other in a second direction. The first edge abuts against and connects to the bottom wall, and the second edge abuts against and connects to the side wall. The first direction and the second direction intersect. The battery device provided in this application can improve load-bearing capacity and reliability.
