the chassis device comprises an oil pump, a motor, an oil line pipeline, an electromagnetic controller and a buffer rubber pad, wherein the rotating shaft is arranged on the left side of the motor, the rotating shaft is connected with the oil pump, the oil pump is connected with the oil line pipeline through an oil pipe connecting piece, the electromagnetic controller is arranged on the left side of the oil line pipeline, and the electromagnetic controller is respectively connected with the oil pipe A and the oil pipe B;
the electromagnetic controller controls the liquid oil in the oil line pipeline to flow to, and controls the opening and closing of the oil pipe A and the oil pipe B according to the intensity of current signals, when the electromagnetic controller opens the opening and closing of the oil pipe A, the liquid oil in the oil pump flows into the upper hydraulic cylinder through the oil pipe A, the pressure in the upper hydraulic cylinder is gradually increased due to the increase of the oil quantity, the liquid oil pushes the piston II to move downwards, and the downward thrust enables the seat device to rotate anticlockwise; when the electromagnetic controller turns on the switch of the oil pipe B and turns off the switch of the oil pipe A, liquid oil in the oil pump gradually flows into the lower hydraulic cylinder through the oil pipe B, the pressure in the lower hydraulic cylinder is gradually increased due to the increase of the oil quantity, the liquid oil pushes the piston II to move upwards, and the upward thrust enables the seat device to rotate clockwise to be vertical; the electromagnetic controller is connected with the pedal controller through a conductive wire, and the pedal controller comprises an upper supporting plate, a lower supporting plate and a potentiometer;
the potentiometer comprises a sliding contact, a static contact piece, an upper wiring and a lower wiring.
2. The medical ultrasonic examination auxiliary arm chair according to claim 1, wherein the upper fastening piece and the inner supporting column body of the telescopic hydraulic cylinder are connected through threads, the inner supporting column body and the piston II are connected through threads, and the lower part of the outer supporting column body and the lower fastening piece are connected through screw threads.
3. The medical ultrasound examination auxiliary arm chair according to claim 1, wherein under the condition of unchanged voltage, when the upper support plate of the foot controller is stepped on or off, the sliding contact slides downwards and upwards along the static contact, so that the resistance of the potentiometer becomes smaller and larger, and the current on the upper wiring and the lower wiring becomes larger and smaller, and the electromagnetic controller controls the opening and closing of the oil pipe A and the oil pipe B according to the change of the current.
