The main body mechanism for automatically converting three postures of the sitting, lying and sleeping three-posture full-automatic business cockpit is introduced, and the action conversion process of the invention is described in detail below.

First, see how the present invention extends from a chair to a reclining chair, and then from the reclining chair to a couch, i.e., from a sitting posture to a lying posture and then to a sleeping posture. Referring to fig. 2, when the crank 14 rotates clockwise, the round connecting rod 13 pulls the swing rod 11 to rotate clockwise, at this time, the clockwise action of the other four-bar mechanism swing rod 11 causes the back board 1 to push the back swing rod 12 to move clockwise, when the back board 1 moves rightward, the seat board 2 moves rightward under the push of the hinge point axis O5 with the back board 1, the right end of the seat board 2 is hinged with the walking frame 20 at O14, the height of the right end of the seat board 2 is restricted by O14, the left end of the seat board 2 sinks when moving rightward, so that the obtuse angle between the seat board and the back board 1 is gradually increased (see fig. 3 and 4), the height difference between the left end and the right end of the seat board 2 in the whole process from the sitting state to the lying state is continuously changed, and the height difference between the left end and the right end of the hinge point O of the seat₅As a result of the rightward and downward movement, the obtuse angle between the backrest plate 1 and the seat plate 2 is continuously changed, and the effect that the left end of the seat plate 2 can be much lower than the right end in the lying process, that is, the height difference between the left end and the right end of the seat plate 2 is very large, so that the comfortable effect that the hip position of the sitting person is far lower than the knee in the lying posture can be achieved, as can be clearly seen from fig. 3 and 4, at this time, another set of four-bar mechanisms (the backrest plate 1, the seat plate 2, the calf plate 3 and the long connecting bar 15) is arranged at the hinge point O between the seat plate 2 and the backrest plate 1₅Under the condition that the angle between the two plates is constantly changed towards the right and downwards, the long connecting rod 15 is used for pushing the shank plate 3 to rotate around the O6 in a counterclockwise way, so that the angle between the shank plate 3 and the seat plate 2 is gradually increased from an acute angle to an obtuse angle, and the angle can be seen from figures 2, 3 and 4When the angle between the backrest plate 1 and the seat plate 2 is increased to an obtuse angle, the angle between the seat plate 2 and the shank plate 3 is increased to an obtuse angle, and the left end of the seat plate 2 is lower than the right end, the S-shaped lying posture which can be laid down is formed, the posture can be changed along with the change of the inclination angle of the backrest plate 1 and the ground, and the lying posture can be adjusted at will. When the included angle between the seat plate 2 and the lower leg plate 3 is changed, four bars consisting of the seat plate 2, the lower leg plate 3, the two bars 18 and the connecting push rod 19 also act, the lower leg plate 3 rotates anticlockwise around the O6 point to drive the connecting push rod 19 to act anticlockwise around the O13, the connecting push rod 19 pulls the two bars 18 to act anticlockwise around the O8, the two bars 18 act anticlockwise around the O8, so that a set of four-bar mechanisms (the foot placing plate 8, the lower leg plate 3, the front end connecting rod 17 and the two bars 18) at the rearmost end act simultaneously, the front end connecting rod 17 acts anticlockwise under the pushing of the two bars 18 to drive the foot placing plate 8 to rotate anticlockwise around the O10, and thus when the crank 14 rotates to be in line with the round notch connecting rod 13 (see figure 5), the included angle between the backrest plate 1 and the ground is horizontal, and the foot placing plate 8 is placed flat. As can be seen from fig. 5, when the back board 1 is in a horizontal posture, the seat board 2, the calf board 3, and the footrest 8 are all in a horizontal state in this order. The whole process from the chair to the reclining chair to the couch is completed.

Then, the invention is seen how to fold the couch from the couch to the couch, and then fold the couch from the couch to the seat, namely, from the sleeping posture to the lying posture to the sitting posture. Referring to fig. 5, when the crank 14 rotates counterclockwise, the round connecting rod 13 pulls the oscillating rod 11 to rotate counterclockwise; at this time, the counterclockwise motion of the swing rod 11 of the other four-bar mechanism (by the swing rod 11, the rear swing rod 12, the backrest plate 1, and the base frame 16) causes the backrest plate 1 to pull the rear swing rod 12 and also to slowly move counterclockwise, at this time, the backrest plate 1 swings counterclockwise and the lower end sinks (refer to fig. 4 and fig. 3), on the one hand, the right end of the seat plate 2 is hinged to the walking frame 20 at O14, the height of the right end of the seat plate 2 is restricted by O14, when the backrest plate 1 moves downward leftward, the seat plate 2 moves downward leftward under the pulling of the hinge point axis O5 of the backrest plate 1, and the left end sinks continuously, so that the included angle between the seat plate and the backrest plate 1 decreases gradually from the horizontal to the obtuse angle (refer to fig. 5, fig. 4 and fig. 3), at this time, the other set of four-bar mechanism (the backrest plate 1, the seat plate 2, the shank 3, and the long connecting rod 15) changes, the long link 15 pulls the shank plate 3 to rotate clockwise around the O6, so that the included angle between the shank plate 3 and the seat plate 2 changes from horizontal to obtuse angle and gradually from obtuse angle to acute angle, which can be seen from fig. 5, 4 to 3 and 2. When the crank 14 rotates anticlockwise, the included angle between the backrest plate 1 and the seat plate 2 is from horizontal to obtuse angle, and the included angle between the seat plate 2 and the shank plate 3 is from horizontal to obtuse angle, so that the lying posture is formed, the posture can be changed along with the change of the inclination angle of the backrest plate 1 and the ground, the lying posture can be adjusted at will, and meanwhile, because the left end of the seat plate 2 is always changed in a sinking way in the whole process from sleeping to lying, the comfortable posture that the hip position in the lying posture of a passenger is far lower than the knee can be formed. When the included angle between the seat board 2 and the shank board 3 changes, four bars consisting of the seat board 2, the shank board 3, the two bars 18 and the connecting push rod 19 also act, the shank board 3 rotates clockwise around the point O6 to drive the connecting push rod 19 to act clockwise around the point O13, the connecting push rod 19 pushes the two bars 18 to act clockwise around the point O8, the two bars 18 act clockwise around the point O8, the front end connecting rod 17 acts clockwise under the pulling of the two bars 18 to drive the foot placing board 8 to rapidly rotate clockwise around the point O10, and thus when the crank 14 rotates to form a line with the round notch connecting rod 13, (referring to figure 2), the backrest board 1 and the seat board 2 form the posture of the seat, the shank board 3 is retracted to the lower side of the seat board 2 to be folded, and the foot placing board 8 is arranged behind the shank board 3, so that the whole process from the reclining chair to the seat is completed.

The foregoing is merely an example of the present invention and various modifications and changes may occur to those skilled in the art, and it is intended to cover in the appended claims any and all changes that fall within the true spirit and scope of the invention.
