Summary of the invention:
Goal of the invention of the present utility model is: the electronic tumbler that a kind of bed accessory backrest is provided.
The electronic tumbler of bed accessory backrest described in the utility model, it comprises a frame, seat back frame, electronic push mechanism, the right-hand member of described seat back frame is rotatably mounted on the frame by shipping and reselling on another market, electronic push mechanism is arranged between a frame and the seat back frame, and the rotation angle of inclination of seat back frame is controlled by electronic push mechanism.
As a kind of embodiment of the present utility model, described electronic push mechanism, comprise motor, drive, power transmission shaft, movable screw female seat, bevel gear nut, bevel gear, screw mandrel, drive and bevel gear are installed on the power transmission shaft, and power transmission shaft is rotatably mounted on the frame; Motor links to each other with power transmission shaft by drive, the bevel gear nut is installed in rotation on the movable screw female seat, and the movable screw female seat is fixed on the frame turningly, and screw mandrel is paid by screw thread with the bevel gear nut and linked to each other, the upper end and the seat back frame of screw mandrel are hinged, bevel gear nut and bevel gear engagement.
As another kind of embodiment of the present utility model, described electronic push mechanism, comprise motor, movable screw female seat, bevel gear nut, bevel gear, screw mandrel, bevel gear is directly installed on the main shaft of motor, and motor is fixed on the frame, and the bevel gear nut is installed in rotation on the movable screw female seat, the movable screw female seat is fixed on the frame turningly, screw mandrel is paid by screw thread with the bevel gear nut and is linked to each other, and the upper end and the seat back frame of screw mandrel are hinged, bevel gear nut and bevel gear engagement.
Described movable screw female seat is made up of bearing, bearing block, screw, ring for fixing and support plate, the bevel gear nut is installed in the bearing, bearing is installed in the bearing block, and bearing block is installed on the ring for fixing by two screws turningly, and ring for fixing is fixed on the support plate that is connected with the bed frame.
Owing on the bed frame, be provided with the leading screw and nut mechanism of energy self-locking, and motor carries out transmission turning by one group of bevel gear, motor can pass through bevel gear, the bevel gear nut drives screw mandrel and moves up and down, the rising of screw mandrel or the meeting that descends drive seat back frame and rotate, the rotational angle size of seat back frame can make the people convert the sitting shape to from the shape that crouches, people are as long as just can regulate the rotational angle of seat back frame by handling motor control switch, to satisfy people's different demands, this back rotation device both had been applicable to hospital, nursing house, in the clinic each is nursing hospital bed, also be applicable to steamer, train, used sleeping berth bed on the coach is equally to also very suitable in the domestic bed accessory.
Description of drawings:

Fig. 3 is the fundamental diagram of example 2;
Among the figure: 1-bed frame; The 2-seat back frame; The 4-screw mandrel; The 5-bevel gear; 6-bevel gear nut; 7-movable screw female seat; The 71-bearing; The 72-bearing block; The 73-screw; The 74-ring for fixing; The 75-support plate; The 8-power transmission shaft; The 9-drive; The 10-motor; 11-ships and resell on another market; The 12-roller; 13-push-pull bar conjunction;
The specific embodiment:
Illustrate the specific embodiment of the present utility model below in conjunction with accompanying drawing:
Example 1: the electronic tumbler of bed accessory backrest described in the utility model, comprise a frame 1, seat back frame 2 and electronic push mechanism, the right-hand member of seat back frame 2 11 is rotatably mounted on the frame 1 by shipping and reselling on another market, described electronic push mechanism is made up of motor 10, drive 9, power transmission shaft 8, movable screw female seat 7, bevel gear nut 6, bevel gear 5 and screw mandrel 4, drive 9 and bevel gear 5 are installed on the power transmission shaft 8, and power transmission shaft 8 is rotatably mounted on the frame 1; Center at bevel gear nut 6 is shaped on female thread, its lower end is provided with the shaft shoulder, the shaft shoulder is installed on the bearing block 72 by bearing 71, bevel gear nut 6 is rotatable with respect to bearing block 72, bearing block 72 is fixed on the support plate 75 by two screws 73 and ring for fixing 74 turningly, support plate 75 is fixed on the bed core frame 1, screw mandrel 4 and bevel gear nut 6 are paid by screw thread and are linked to each other, the push-pull bar conjunction 13 at the upper end of screw mandrel 4 and seat back frame 2 back sides is hinged, bevel gear nut 6 and bevel gear 5 engagements, motor 10 drives drive 9 and rotates, bevel gear 5, bevel gear nut 6 will rotate thereupon, because bevel gear nut 6 is defined at the degree of freedom of screw mandrel direction, bevel gear nut 6 rotates, 4 of screw mandrels rise or descend along its axis, rotate thereby drive seat back frame 2, when screw mandrel 4 rises, the ship and resell on another market 11 upwards commentaries on classics of seat back frame 2 on bed frame 1, when screw mandrel 4 rose to the limit, seat back frame 2 went to the position perpendicular to bed frame 1; Otherwise when screw mandrel 4 descended, seat back frame 2 pin 11 that rotates changeed downwards, and seat back frame 2 is changed to level from plumbness.People strengthen the comfort that people lie on a bed and recuperate as long as just can control the angle of inclination that seat back frame rotates freely by handling motor switch.
