The driving structure of the lead screw and the nut can accurately control the lifting and descending movement of the lifting frame 243, and adjust the state of the cover plate assembly.

[0175] In some possible embodiments, the rear cover plate 230 is connected to the table head 210 through a damping hinge, an operation shaft is arranged on the table head 210, the operation shaft is in transmission connection with the lead screw, and the operation shaft is used to rotate under the action of an external force to drive the lead screw 245 to rotate. When the driver's table 200 is powered off, the driving mechanism fails, and the rear cover plate 230 can be manually lifted to stop at any position. The operator can adjust and stow the front cover plate 220 by rotating the knob operation shaft.

[0176] In some possible embodiments, a master lock and a control knob are arranged on the cab 210, and the control knob has an opening gear and a closing gear. When the master lock is in an unlocked state, the control knob is rotated to the opening gear, and the driving mechanism is triggered to drive the cover plate assembly to move to at least partially retract, so that the cab operating assembly is exposed. When the master lock is in the unlocked state, the control knob is rotated to the closing gear, and the driving mechanism is triggered to drive the cover plate assembly to move, so that the cover plate assembly closes the upper opening.

[0177] It should be noted that the cab 210 is provided with a driving mechanism controller, and the control knob is electrically connected to the controller. When the knob is rotated, the corresponding gear signal can be sent to the driving mechanism controller. When the driving mechanism controller receives the gear signal, the corresponding driving instruction can be sent to the driving mechanism.

[0178] The cover plate assembly is provided with an automatic locking device. In order to avoid that the passengers open the cover plate and ensure the safety of train driving, a master lock and a control knob are additionally arranged at the lower right corner of the center console. The master lock can only be opened by the key of the cab controller, and the inside of the lock is provided with a contact. After the lock is opened, the control knob is rotated to the opening gear, the motor 244 is powered, the cover plate assembly is flipped and then sinks, the control knob is rotated to the closing gear of the cover plate, the motor 244 is reversed, the cover plate assembly is lifted and then covers, and if the master lock is in the closed state, the motor 244 cannot be powered after the control knob is rotated, and the cover plate assembly has no response.

[0179] When the cab is abnormally powered off, a manual opening scheme is arranged to ensure that the cover plate assembly can be opened. The cab 200 is closed by two cover plates. When powered, the rear cover plate 230 is flipped by the pushing of the electric push rod 251. The electric push rod 251 and the supporting rod 253 are connected by the electromagnetic clutch 252. The supporting rod 253 is directly fastened to the rear flap. The electromagnetic clutch 252 is connected to the train battery. Under normal circumstances, it is powered to keep the connection state of the supporting rod 253 and the electric push rod 251. The electric push rod 251 locks the rear cover plate 230 and cannot be opened due to the self-locking effect. The front cover plate 220 cannot be opened due to the self-locking effect of the motor 244.

[0180] If manual switching to the manual driving mode is required, the control knob needs to be rotated to the manual gear first. At this time, the electromagnetic clutch 252 is powered off and released. The supporting rod 253 and the electric push rod 251 lose the transmission connection relationship. The rear cover plate 230 loses the self-locking effect of the electric push rod 251 and can be manually opened. The hinge of the rear cover plate 230 is a damping hinge, and the rear cover plate can stop at any position after being opened. After the rear cover plate 230 is manually opened to the specified position, the front cover plate 220 is retracted by rotating the rotating shaft 17224 of the detachable rocker at the footrest.
