[0043] Among them, the shell 11 forms a accommodating cavity 11a that penetrates in the first direction; the back panel 12 and the door panel 13 are opposite to each other in the first direction, and are respectively covered on the two open ends of the accommodating cavity 11a; the interactive device 14 is hinged to the shell 11; the functional unit is constructed as at least one and is arranged on the back panel 12 and accommodated in the accommodating cavity 11a.

[0044] Specifically, the shell 11 has a accommodating cavity 11a, and the shell 11 can provide good support, fixation and protection for the components (such as functional units) in the accommodating cavity 11a. Both ends of the accommodating cavity 11a in the first direction are open. The back panel 12 and the door panel 13 can be respectively covered on the open ends of the accommodating cavity 11a to close the accommodating cavity 11a, thereby protecting the components in the accommodating cavity 11a from external damage.

The functional unit of the elevator control cabinet 1 can be arranged on the side of the back plate 12 close to the shell 11 in the first direction. By connecting or disassembling the back plate 12 and the shell 11, the functional unit can be installed in the accommodating cavity 11a of the shell 11 or the functional unit can be removed from the accommodating cavity 11a. Therefore, the elevator control cabinet 1 has an open installation and maintenance environment.

After the functional unit and the back plate 12 are connected to form an integral structure, the shell 1 1 can be directly buckled on the back plate 12 along the first direction, and the functional unit is accommodated in the accommodating cavity 11a along the first direction to complete the assembly and fixation between the shell 11 and the back plate 12 and the functional unit. Since the shell 11 is assembled after the functional unit is connected to the back plate 12, the assembly operation of the functional unit and the back plate 12 will not be limited by the space in the shell 11, and the functional unit can be arranged as close to the edge as possible. In this way, the assembly process gap between the functional unit and the inner wall of the shell 11 can be optimized, and the space utilization rate can be further improved, and the product volume can be reduced. According to actual case tests, it can be 45% of the volume of traditional similar control cabinets.

The power board 1531 can provide an installation position for the third sub-functional element 1533 to ensure that the third sub-functional element 1533 works normally. The third sub-functional element 1533 can draw power from the three-phase alternating current input by the drive board 1511, and then convert it into power supplies of various voltage levels to power various parts in the driver in the elevator system. Similarly, by integrating the power board 1531, the capacitor board 1532 and the third sub-functional element 1533 into a third functional unit, the layout space can be saved, and the power supply and capacitor parts can be modularized and standardized.

[0064] like Figure 3 As shown, the elevator control cabinet 1 also includes: a second fan assembly 16, the shell 11 has two opposite side panels 111, and defines a second air duct for dissipating heat for the fourth sub-functional unit 154, each side panel 111 is formed with second air holes 111a connected to the second air duct at intervals in the extension direction, and the second fan assembly 16 is arranged on the side panel 111 and opposite to the second air holes 111a.
