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 oscillating rod 11 to rotate clockwise; at this time, the clockwise action of the other set of four-bar mechanism swinging rod 11 makes the backrest plate 1 push the rear swinging rod 12 to also act clockwise, when the backrest plate 1 moves to the right, the seat plate 2 is at the hinge point axis O with the backrest plate 1₅Is also moved to the right by the push of the base plate 2, and the right end of the base plate is hinged with the walking frame 20To O is connected to₁₄The right end height of the seat plate 2 is O₁₄The restraint is that the left end sinks when the seat board 2 moves in the right direction, the obtuse angle between the seat board and the backrest board 1 is gradually increased (refer to fig. 3 and 4), at the moment, under the change of the angle between the seat board 2 and the backrest board 1, the other set of four-bar mechanism (the backrest board 1, the seat board 2, the shank board 3 and the long connecting rod 15) pushes the shank board 3 to wind the shank board 3 around the O₆The included angle between the counterclockwise rotation and the seat board 2 is gradually increased from an acute angle to an obtuse angle, and the change can be seen from fig. 2 to fig. 3 and fig. 4, at this time, the included angle between the back board 1 and the seat board 2 is increased to the obtuse angle, and the included angle between the seat board 2 and the shank board 3 is increased to the obtuse angle, so that the lying posture is formed, the posture can be changed along with the change of the inclination angle of the back board 1 and the ground, and the lying posture can be adjusted at will. When the included angle between the seat board 2 and the lower leg board 3 is changed, four bars consisting of the seat board 2, the lower leg board 3, two bars 18 and a connecting push rod 19 also act, and the lower leg board 3 winds the O₆The point rotates counterclockwise to drive the connecting push rod 19 to rotate around the O₁₃Acting counterclockwise, the connecting rod 19 pulling the two-section rod 18 around O₈Acting counter-clockwise, with the two-stage rod 18 about O₈The counterclockwise motion of the two rods causes a set of four-bar mechanism (composed of the foot placing plate 8, the shank plate 3, the front end connecting rod 17 and the two rods 18) at the rearmost end to simultaneously move, and the front end connecting rod 17 moves under the push of the two rods 18 to drive the foot placing plate 8 to surround the O₁₀The back rest board 1 rotates anticlockwise, so that when the crank 14 rotates to be in line with the round connecting rod 13, the included angle between the back rest board 1 and the ground is horizontal, and the foot placing board 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 other four-bar mechanism (consisting of the swing rod 11, the rear swing rod 12, the back board 1 and the base frame 16) swing rod 11 causes the back board 1 to pull the rear swing rod12 also slowly moves counterclockwise, at the same time, the back board 1 swings counterclockwise and the lower end sinks (refer to fig. 4 and 3), the right end of the seat board 2 is hinged with the walking frame 20 at O₁₄Right end height is subjected to₁₄Restrain, when the back board 1 moves leftwards, the seat board 2 is at the hinge point axis O with the back board 1₅The angle between the two four-bar mechanisms (the back board 1, the seat board 2, the shank board 3 and the long connecting rod 15) is gradually reduced, and at the same time, under the condition that the angle between the two four-bar mechanisms (the back board 1, the seat board 2, the shank board 3 and the long connecting rod 15) is changed between the seat board 2 and the back board 1, the long connecting rod 15 pulls the shank board 3 to rotate around the O₆The angle between the clockwise rotation and the seat plate 2 gradually changes from a blunt angle to an acute angle, which can be seen from the sequential views of fig. 4 to fig. 3 and fig. 2. When the crank 14 rotates counterclockwise, 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, and the lying posture can be adjusted at will. When the included angle between the seat board 2 and the lower leg board 3 is changed, four bars consisting of the seat board 2, the lower leg board 3, two bars 18 and a connecting push rod 19 also act, and the lower leg board 3 winds the O₆The point rotates clockwise to drive the connecting push rod 19 to wind the O₁₃Acting clockwise, the connecting push rod 19 pushes the two-section rod 18 around O₈Acting clockwise, with the two-stage rod 18 about O₈The front end connecting rod 17 moves clockwise under the pulling of the two-section rod 18 to drive the foot placing plate 8 to wind around the O₁₀When the crank 14 rotates to be in line with the round notch connecting rod 13 (see figure 2), the backrest plate 1 and the seat plate 2 form the posture of the chair, the shank plate 3 is retracted to the lower part of the front surface of the seat plate 2, and the foot placing plate 8 is folded at the back of the shank plate 3, thereby completing the whole process from the sleeping chair to the deck chair to the chair.
