meanwhile, when the rotating disc assembly 4 and the lifting assembly 2 rise to a high-numerical controller prestored in the controller under the driving of the lifting driving motor 8, a signal is sent to a lifting motor control module, and the lifting motor control module controls and drives the lifting driving motor 8 to stop running; at this time, the surface of the table top on the table top shell 37 is completely unfolded and is in a horizontal position and a proper height, and the surface of the table top on the table top shell 37 can be used by passengers;

when the desk top is in a normal working state, when the angle of the backrest of the seat changes or the vehicle encounters a sharp turn, a convex-concave road surface, a deceleration strip and the fluctuation of the vehicle body in the running process, the whole posture of the desk shell 37 changes, at the moment, the gyroscope gravity sensing module 1 converts the detected posture change into corresponding electrical parameters and feeds the electrical parameters back to the controller, the controller respectively sends corresponding correction instruction parameters to the control driving motor control module 29, the rotating motor control module and the lifting motor control module at the same time according to the signals, then the driving motor control module 29 and the rotating motor control module are driven, the lifting motor control module respectively controls the driving motor, the rotating driving motor 7 and the lifting driving motor 8 in the corresponding desk shell to synchronously cooperate with each other to quickly correct the running state according to the corresponding correction instruction parameters, stopping until the table top on the table top shell 37 is in the horizontal position and the table top is at a proper position away from the carriage;

when the desk is not needed, the user starts the closing button on the control screen 35, starts the controller module 36, the controller module 36 firstly sends a signal instruction of resetting self-checking of the rotating component 4 to the rotating motor control module, if the resetting sensing protrusion on the movable disk 12 is aligned with the rotating position sensing module installed on the fixed disk 11, the rotating position sensing module 18 generates a signal and feeds the signal back to the controller, the controller receives the feedback signal, if no parameter signal is fed back to the controller, the controller sends a corrected parameter signal to the rotating motor control module according to the pre-stored initial angle information parameter and the instant data of the gyroscope gravity sensing module 1 stored by the controller, the rotating motor control module controls the rotating driving motor 7 to rotate and adjust according to the corrected parameter signal, and then drives the movable disk 12 to rotate in the corresponding direction, until the reset sensing protrusion of the movable tray 12 is aligned with the rotation position sensing module installed on the fixed tray 11, the rotation position sensing module 18 generates a signal, and feeds back the feedback signal to the controller, after the controller receives the feedback signal, the controller simultaneously sends a closing signal instruction to the driving motor control module 29, the gyroscope gravity sensing module 1 and the lifting motor control module, at this time, the gyroscope gravity sensing module 1 obtaining the signal instruction stops monitoring the whole attitude change of the table shell 37, the driving motor control module 29 obtaining the signal instruction controls the driving motor in the table shell to rotate reversely, the hinge assembly 5 rotates anticlockwise relative to the table shell 37 under the driving of the driving motor in the table shell, meanwhile, the rotation movement enables the hinge assembly 5 to move downwards relative to the table base 3, and the table shell 37 is driven by the hinge assembly 5 to move inwards and retreats relative to the table base 3; meanwhile, the lifting motor control module which obtains the signal instruction controls the lifting driving motor 8 to rotate reversely, as the lifting driving motor 8 is in transmission connection with the lifting assembly 2 and is used for driving the lifting assembly 2 to do descending motion, the lifting assembly 2 moves downwards relative to the table base under the driving of the lifting driving motor 8, and as the rotating disc assembly 4 is fixedly connected with the lifting assembly 2 and the rotating disc assembly 4 is connected with the hinge assembly 5, the rotating disc assembly 4 moves downwards relative to the table base along with the descending of the lifting assembly 2 so as to drive the whole table shell 37 to move downwards, and when the table shell 37 descends to the lowest height position relative to the table base 3, the lifting position sensing bulge 24 on the sliding block 22 is just aligned with the origin of the sensing area of the lifting position sensing module 23 which is arranged at the lower end of the sliding rail 21; the lifting position sensing module 23 generates a signal and feeds the signal back to the controller, the controller sends a signal to the lifting motor control module, the lifting motor control module controls and drives the lifting driving motor 8 to stop running, and the descending process is finished; when the lower limit position sensing protrusion on the position detection plate 33 is just opposite to the sensing area origin of the table shell internal position sensing module 34 installed on the inner side of the table shell 37, the table shell internal position sensing module 34 is triggered to generate a signal and feed the signal back to the controller, the driving motor control module 29 is controlled to control the driving motor in the table shell to stop running, at this moment, the table shell 37 is completely retracted into the table base 3, and the whole retracting process is finished.
