The user can actively control the rotating motor 4 to change the lifting state of the upper body rest board 16 and the lower body rest board 17 of the sofa chair.
[0025] Working principle: When the utility model is implemented, when the user needs to lie down, first start the lifting controller 27, the rotating motor 4 rotates clockwise, and the first driving sprocket 6 and the second driving sprocket 7 fixedly mounted on the rotating rod 5 rotate clockwise.
[0026] The first driving sprocket 6 drives the first chain 11 to move clockwise, the first chain 11 drives the first driven sprocket 10 to move clockwise, and the first connecting rod 14 fixedly connected to the first driven sprocket 10 drives the upper body rest plate 16 to fall;
[0027] The second active sprocket 7 drives the second chain 13 to move clockwise, and the second chain 13 drives the second driven sprocket 12 to move clockwise, and the second connecting rod 15 fixedly connected to the second driven sprocket 12 also drives the lower body rest plate 17 to rise.
[0028] When the user needs to sit up, first start the lifting controller 27, rotate the motor 4 counterclockwise, and change the direction of the rotating rod 5 to the counterclockwise direction. The same principle as above is used to finally raise the upper body rest board 16 and lower body rest board 17.
