[0002] In the fields of multimedia conference rooms, smart homes, building automation, industrial control systems, etc., with the continuous increase in the types of devices and the increasing complexity of functions, the traditional decentralized control mode has been difficult to meet the requirements of efficient and convenient management; therefore, a central control host is used as a control terminal to control each device. As an important part of modern automation and intelligent systems, its generation and development stem from the urgent need for centralized management and efficient control of complex devices.

[0003] However, in the current design of the mainframe chassis, the chassis is generally assembled by fixing six boards, namely the upper, lower, front, rear, left, and right boards, with screws. There is no positioning structure between the six boards, resulting in the need to adjust and align the screw holes multiple times during assembly, and the boards need to be assembled one by one, that is, after fixing one board with screws, then fixing the next board, increasing the assembly difficulty and complexity.
