[0038] Figure 1 FIG. 1 is a structural diagram of a machine room-less elevator control cabinet 100 according to an embodiment of the present invention. Figure 2 for Figure 1 Schematic diagram of the structure of the machine room-less elevator control cabinet 100 when electrical components are installed. Figure 3 for Figure 1 FIG. 1 is a schematic diagram of a partial structural decomposition of a machine room-less elevator control cabinet 100. Figure 4 for Figure 1The front view of the machine room-less elevator control cabinet 100 is shown in FIG. Figure 1 and 3 As shown, in one embodiment, the machine room-less elevator control cabinet 100 includes a housing assembly 10, a beam 20 and a wire duct structure 30 (see Figure 4 ). The housing assembly 10 has a cavity 101 inside, and includes an openable front cover 11. In one embodiment, the housing assembly 10 includes a main body 12, an opening is formed on the front side of the main body 12, and the front cover 11 is disposed at the opening. Here, the front cover 11 can be a whole panel that can be opened as a whole, or it can be a panel that can be opened as a whole. Figure 1 The housing 101 includes an upper cover 111 and a lower cover 112 arranged in sequence. The upper cover 111 is configured to be openable and closable. The upper cover 111 and the lower cover 112 together close the opening on the front side of the main body 12. The crossbeam 20 is fixedly arranged in the cavity 101 and arranged along the transverse direction of the housing. The two ends of the crossbeam 20 are respectively fixedly connected to the two sides of the cavity 101. The side of the crossbeam 20 close to the front cover 11 is used to install the power input module 110 (see Figure 2 ), the two sides of the crossbeam 20 in the thickness direction (i.e., the front-to-back direction of the control cabinet) are respectively used to lead out the two lines of the power input module 110. A wire trough structure 30 is disposed within the cavity 101 and located on the side of the crossbeam 20 that is used to lead out the two lines of the power input module.

In one embodiment, the crossbeam 20 is sequentially provided with multiple mounting holes 201 along its length. The mounting holes 201 are used to install the circuit breakers of the power input module 110. The two lines of the power input module 110 can refer to the primary line (thick line) and secondary line (thin line) of the circuit breaker. For example, the secondary line is led out from the rear side of the crossbeam 20 (i.e., the side away from the front cover 11) and then enters the wire duct structure 30. The primary line is led out from the side of the circuit breaker, also toward the side where the wire duct structure 30 is located. Since the circuit breaker is mounted on the side of the crossbeam 20 close to the front cover 11, the primary line is led out from the side of the circuit breaker on the side of the crossbeam 20 close to the front cover 11. The above-mentioned machine room-less elevator control cabinet 100 is embedded in the building at the top of the hoistway, thereby saving space.

[0039] In this embodiment, a crossbeam 20 is provided for mounting a power input module 110.
