Description

Auto-controlled electric rocking chair

The present invention relates to a kind of rocking chair, particularly be suitable for the structure and the manufacture method thereof of the elderly's auto-controlled electric rocking chair.

Rocking chair generally dangle formula and pommel horse formula.The formula of dangling be by suspension holdfast with the seat portion sub-support on the chair frame because the drive of human body, seat moves back and forth in the horizontal direction; Pommel horse formula rocking chair is that seat partly is fixed on the semicircle sled frame that two two ends are upturned.Because sled frame landing part is the peak of radius of circle all the time, no matter at which side exerts pressure a little, rocking chair will rock front and back.Though two kinds of rocking chair forms of motion differences, common ground is: must be driven by human body.This mainly is because lack power set.

Purpose of the present invention, exactly in the selection, on the structure and on the manufacturing process original rocking chair is reformed, and provide a kind of and do not need manually to shake, can sit and lie, can shake can change, the electromechanical integration auto-controlled electric rocking chair.

The object of the present invention is achieved like this: design handrail post, the location sector of setting the position tenon in a kind of handrail by the chair back, band location tenon pressing plate, the hollow, go up suspension holdfast, running-board bracket connects ear, running-board bracket, gangbar, pedal; The auto-controlled electric rocking chair that flexible material skirt cover, mounting base plate, following suspension holdfast, suspension arms, swing arm link rod, rocking arm, rocker arm shaft, thumb wheel, output shaft of gear-box, gearbox, gearbox power shaft, shaft coupling, motor, controller, lead, power supply, controller panel and backing board, axis, universal wheel are formed, be characterized in: with the chair back of steel wooden frame, sponge liner, leather envelope, middle part two Side link with bearing pin and handrail; The lower end with bearing pin with link with the seat cushion rear end of steel wooden frame, sponge liner, leather envelope; Seat cushion middle part two Side have handrail post bearing pin and location sector; Handrail post is a hollow tube, and upper end and handrail link, interior setting position tenon, spring and tenon tappet, and tenon tappet upper end links with bearing pin and the pressing plate of being located at below in the handrail; The seat cushion lower front is provided with running-board bracket and connects ear, and the running-board bracket upper end links with the connection ear, and the middle part links with gangbar and handrail post lower end, and lower end and pedal link; The seat cushion below is provided with two pairs and goes up suspension holdfast, and frame is on the axle of swing arm lower end, front and back respectively; The swing arm upper end, on the following suspension holdfast of mounting base plate, wherein one group of swing arm lower end is combined as a whole by the swing arm link rod with axis suspension, and the middle part links by rocking arm and rocker arm shaft, thumb wheel; Thumb wheel is fixed on the output shaft of gear-box, and gearbox links by power shaft, shaft coupling and motor; Motor is controlled by the controller by lead; Controller is made up of micro computer and device for switching, and links by lead and controller panel; Until the mounting base plate, made a circle skirt cover with flexible material around seat cushion, there is an axis at mounting base plate middle part, links by axis hole and backing board, and backing board is divided into four to six universal wheels, guarantees the stable of whole rocking chair and moves flexibly.At ordinary times, rocking chair remains static because of unpowered effect.When connecting controller power source, and by the controller panel respective keys, input schedule operating time and startup command, controller is connected power supply, motor start-up automatically, and by shaft coupling drive gearbox and output shaft, thumb wheel rotates, because the rocker arm shaft center is in the eccentric position at relative output shaft of gear-box center, so, when thumb wheel rotates; it is the center with the output shaft of gear-box that rocker arm shaft drives rocking arm, seesaws up and down; Because the rocking arm other end and swing arm link rod link, so, just, change the reciprocating motion in the horizontal direction of swing arm link rod into the rotatablely moving of thumb wheel; Because the seat part is suspended on the arm shaft by support, so seat also rocks back and forth together thereupon.When rocking chair work when giving first setting-up time, controller is cut off the electricity supply automatically, rocking chair returns to inactive state again.

Because the different needs of people's different time, the chair back can be adjusted to different angles; During adjustment, both hands have been held the location depressor pressing plate under the handrail of the left and right sides respectively, make the location tenon break away from the location sector, lean back the chair back, handrail post upper end hypsokinesis thereupon; Because leverage, the handrail post lower end promotes running-board bracket and pedal forward by link rod simultaneously forward, lies after one's death on the human body, and shank is raised by pedal, the approximate strong attitude that lies low; This moment, both hands unclamped location depressor pressing plate, and the location tenon is stuck in the relevant position of location sector downwards under spring action, and the chair back, handrail post just are fixed.

On the contrary, both hands have been held the location depressor pressing plate under the handrail of the left and right sides respectively, make the location tenon break away from the location sector, body forward, and the chair back, handrail post upper end are thereupon forward; Receive behind running-board bracket and the pedal, shank is put down, and the human body upper body is again sits up straight posture; Unclamp location depressor pressing plate, the chair back, handrail post are fixed to stand up position again.

Below in conjunction with the embodiment accompanying drawing, the present invention will be further described:
