[0025] A front cavity 20 is provided at the lower front side of the interior of the machine body 1, and slide bars 8 are provided at both ends of the bottom of the interior of the front cavity 20. A limit block is provided on the outer side of the slide bar 8, and a tray 9 is movably provided on the slide bar 8. The gas tank 3 is provided on the tray 9, and an air pipe is connected to the gas tank 3. A spring wheel is provided at the middle position of the outer bottom side of the tray 9. An operation display panel 10 is provided at the upper front side of the machine body 1.

An operation display panel 10 is provided at the upper front side of the machine body 1. During use, the guide block 6 is pulled along the guide rail 5 by the drive unit, which can drive the linkage arm 7 to move and rotate, thereby pushing the electrical control board 2 to rotate with the lower hinge as the fulcrum, tilting it out of the rear cavity 4, and by pulling the tray 9, the tray 9 moves along the slide bar 8, making it convenient to pull the gas tank 3 out of the front cavity 20 without disassembly, which is convenient for maintenance and debugging operations.

[0034] Universal wheels 19 are provided at the four corners of the bottom of the body 1 to facilitate the movement of the body 1. A rear door 21 is connected to the rear cavity 4, and a front door 22 is connected to the front cavity 20. The rear door 21 and the front door 22 are used to open the internal electrical control board 2 and the gas tank 3 for maintenance.

[0035] The operation display panel 10 includes an ammeter, voltmeter, pressure gauge, status indicator light, a status switching switch, and a multi-vehicle switching switch. The electrical control panel 2 includes a programmable logic controller (PLC), contactors, relays, a power module, and a terminal block. The multi-vehicle switching switch is used to send signals to the PLC. After the PLC interprets the signals, it outputs control instructions, controlling the opening and closing mechanism via the contactors and relays. The gas tank 3 is used to maintain pressure, connect to the air source, and transmit air to the opening and closing mechanism. During use, the multi-vehicle switching switch on the operation display panel 10 sends signals to the PLC. After the PLC interprets the signals, it outputs control instructions, controlling the opening and closing mechanism via the contactors, relays, and other components, thereby achieving the functions of different vehicle models, saving time and effort and increasing efficiency.

[0036] This comprehensive test bench for the opening and closing mechanism of a train set uses a drive unit to pull a guide block 6 along a guide rail 5, driving a linkage arm 7 to move and rotate, thereby driving the electrical control panel 2 to rotate at its lower hinge point, tilting it out of the rear chamber 4. Pulling a tray 9 causes it to move along a slide bar 8, allowing the gas tank 3 to be pulled out of the front chamber 20 without disassembly, facilitating maintenance and commissioning. Furthermore, the electric telescopic rod 12 pulls the guide block 6, causing the electrical control panel 2 to rotate and extend out of the rear chamber 4 without disengaging. Pulling the tray 9 causes the front end of the tray 9 to extend out of the front chamber 20. At this point, a spring wheel elastically extends and supports the ground, keeping the gas tank 3 in the front chamber 20, allowing it to follow the train set 1 as it moves. This eliminates the need for multiple carry-on operations and enhances ease of use. Furthermore, a multi-vehicle switching switch on the operation display panel 10 sends a signal to a programmable logic controller, which interprets the signal and outputs a control command. This controls the opening and closing mechanism through components such as contactors and relays, thereby achieving the desired functionality for different vehicle types, saving time and effort and increasing efficiency.
