Thus, the output shaft of the linear motor can drive the first cabinet door 32 to rotate relative to the cabinet body 31 around the third pivot axis to open (as shown in Figure 5 ) or close (as shown in Figure 6 ) the first opening 312. As another embodiment, the base of the linear motor is fixedly installed on the cabinet body 31; the output shaft of the linear motor is fixedly installed on the first cabinet door 32, so that the output shaft of the linear motor can drive the first cabinet door 32 to move relative to the cabinet body 31 to open or close the first opening 312.

As one of the specific embodiments, the base of the rotary motor is installed on the cabinet body 31, and the output shaft of the rotary motor is installed on the first cabinet door 32. Thus, the first cabinet door 32 can be directly driven by the rotary motor to rotate around the central axis of the output shaft of the rotary motor to open (as shown in Figure 5 ) or close (as shown in Figure 6 ) the first opening 312.

[0036] As one of the embodiments of the control module 211, the control module 211 can adopt a PLC or an MCU.
