Furthermore, when the two seat boards are closed, the two seat boards are combined into a large seat board.

The control device controls the starting of the driving motor, the electric push rod and the double-output speed reducing motor to operate in order, and comprises a wireless remote controller and a wired controller. The wireless remote controller is convenient for the nursing staff to remotely control. The wired controller is convenient for a user to sit on to control walking by himself.

Two blocks of seat boards are in a closed state in an initial state, the two seat boards are horizontally closed to form a large seat board, the buttocks of the old are seated on the seat boards, feet are placed on the foot boards, knees are located at the knee top boards, and the armrests are held by hands.

From the living chair device sitting to the bed phase: when the old person needs to sit on the bed, the wireless remote controller starts the driving motor, the driving motor drives the driving wheel and the universal wheels drive the whole living chair to gradually approach the bed until the opening frame of the bottom frame is completely inserted into the bottom of the bed, and the wireless remote controller locks the driving motor to keep the living chair still.

The electric push rod is opened through the wireless remote controller and drives the piston rod to slowly contract, and the connecting rod is fixedly connected with the piston rod and is rotatably connected with the crank through the middle pin shaft, so that the connecting rod is driven to move downwards when the piston rod slowly contracts, and the crank is driven to swing under the action of the middle connecting pin shaft. The crank and the upper end handle are fixedly connected, and the upper end handle and the lower end handle are connected through a hinge, so that the upper end handle swings upwards along with the swinging of the crank. When the upper end handle is held by hands, the standing assisting effect can be achieved.

When the old people stand up, the old people start the dual-output speed reducing motor through a dual-output shaft worm gear and a dual-output speed reducing motor at the front end of the wireless remote controller, the first transmission shaft is driven to rotate through the coupler, and the first transmission shaft is fixed on the front side of the supporting transverse frame through the first bearing with a base. Because the tail end of the transmission shaft is provided with the bevel gear I which is meshed with the bevel gear II of the transmission shaft II, the power of the worm gear and worm double-output speed reduction motor with double output shafts is transmitted to the transmission shaft II, and the two ends of the transmission shaft II are fixed on the two side surfaces of the living chair through the bearing with the second seat; because the tail end of the second transmission shaft is provided with a third bevel gear and a fourth bevel gear is fixed below one corner of the two back seat plates through a bevel gear fixing sleeve, the power on the second transmission shaft is transmitted to the upper surface of the fourth bevel gear through the meshing of the third bevel gear and the fourth bevel gear; because the bevel gear four is fixed on one corner of the seat plate and the inside of the bevel gear four is provided with the rotating shaft through the bearing with the seat, when the bevel gear four rotates under stress, the two seat plates are driven to rotate outwards by the position center of the rotating shaft until the four seat plates are completely opened by the rotation degree.

At the moment, the electric push rod is started again through the wireless remote controller to drive the piston rod to slowly extend out, and because of the conversion of the middle crank-slider mechanism, the handle at the upper end slowly swings downwards, so that the old holds the handle to assist the old to slowly sit on the bed. At the moment, the wireless controller is used for starting the driving motor, and the driving wheel and the universal wheels thereof are driven by the driving motor to remotely control the whole device to get away from the bedside.

Stage from sitting on bed to sitting on the chair: the living chair is remotely controlled to the bedside by controlling the driving motor through the wireless remote controller, and the opening frame at the rear part of the underframe is inserted into the bed bottom and is positioned at the position when the user starts to get on the bed. Then the wireless remote controller is pressed down, the electric push rod starts the piston rod to slowly contract, the handle at the upper end is slowly swung upwards through the motion conversion of the crank-slider mechanism, and the old can slowly and safely stand in the living chair by holding the handle at the upper end;

at the moment, the worm gear and worm double-output speed reducing motor with the double output shafts at the front end is started, the remote transmission is realized through a series of bevel gear transmission sets, two back seat boards are slowly turned to the inner side to be closed by taking the rotating shaft as the center, the two seat boards are combined into a large seat board, the electric push rod is started again through the wireless remote controller, the piston rod slowly extends out, the handle at the upper end slowly swings downwards, the handle is held by the old, the old sits on the two back seat boards slowly, the movement of the electric push rod stops, the old sits on the intelligent living chair safely, and the movement of the whole intelligent living chair is controlled through the wired controller on the living chair.

The living chair can also be used for assisting the old people to go to the toilet, and the operation steps and the working principle are the same as the above.

This kind of old person's intelligence chair of living, when the old person need stand, upper end handle and lower extreme handle slope swing up gradually make upper end handle and lower extreme handle on a vertical line, give the old person when standing supplementary ascending power gradually this moment. When the old person sits down, the upper end handle and the lower end handle swing downwards on a vertical line to enable the upper end handle and the lower end handle to incline gradually, and an auxiliary downward force is given to the old person to sit down. The arrangement of the handle at the upper end enables the old to stand and sit down, and gives the old a gradually upward or downward assisting force support, so that the old can stand or sit down safely and slowly.

The bedplate drives bevel gear group through dual output axle gear motor and opens automatically when old person stands, the old person of being convenient for unimpeded get on bed. When the old person gets into in the daily life chair, rethread dual output shaft gear motor drives bevel gear group self-closing, is convenient for the old person to sit on.

The invention has the beneficial effects.

1. According to the intelligent living chair for the old, the electric push rod controls the piston to stretch and descend to drive the crank to swing when the slider of the crank-slider mechanism is used as a driving piece, and the crank swings to drive the handle at the upper end to swing up and down, so that the old can stand and sit on the bed in an auxiliary mode when getting on or off the bed.
