The intelligent control module 22 determines which modality it is when a change instruction is received.

If the sofa is in the first conversion state, the first motor rotates forwards to drive the wheels 19 to move forwards, so that the separable base 2 is separated from the fixed sofa backrest 1, and when the sofa travels to a first designated distance, the separable base 2 is positioned in front of the fixed sofa backrest 1 by 3.5 times of the length of the base of the rotary table 3, the first motor stops rotating and is in a locking state, and meanwhile, the sofa is in a fixed state. Subsequently, the third motor 17 operates to drive the screw rod 16 to rotate forward through the bevel gear 18, and further drive the screw nut 15 to advance along the direction of the screw rod 16, the screw nut 15 drives the first slide bar 12 fixedly connected therewith to move, and the first slide bar 12 is connected with the second slide bar 13 through the auxiliary connecting rod 14, so as to drive the second slide bar 13 to do the same movement. The lifting table top 7 is raised to a first designated height, which is the same as the height of the seat of the fixed sofa backrest 1. The fourth motor and the fifth motor operate to drive the cam 5 to rotate, and then the cam 5 drives the cam groove 4 to do straight-line ascending motion, so that the first lifting chair seat 6 and the second lifting chair seat 8 are lifted to the same height as the fixed sofa backrest 1 seat, namely the first designated height, and then the operation is stopped and locked. The second motor 10 operates, the second motor is the flexible reciprocating motor of direct current motor push rod, and the extension of connecting rod 11 leads to rotary table 3 and fixed sofa back 1 contained angle grow, and then rotary table 3 uses quarter circular arc track motion, and second motor 10 stops the operation when rotary table 3 bottom surface and ground parallel and level, and the sofa is changed to the large-scale passenger table of first transform form by former form this moment. If the rotary table needs to be restored to the original state, a reset instruction is input, the direct current motor push rod stretches and reciprocates the second motor 10 to rotate reversely, the connecting rod 11 is retracted, and the rotary table 3 is driven to rotate to the reset state. The fourth motor and the fifth motor are unlocked and continue to rotate to drive the cam 5 to rotate, the cam 5 drives the cam groove 4 to do linear descending motion, and the first lifting chair seat 6 and the second lifting chair seat 8 are lowered to the original height. Subsequently, the third motor 17 reversely rotates to drive the screw rod 16 to reversely rotate through the bevel gear 18, the screw rod 16 reversely rotates to drive the screw rod nut 15 to retreat along the direction of the screw rod 16, and then the first slide bar 12 and the second slide bar 13 connected with the screw rod nut 15 reversely move to drive the lifting table top 7 to linearly descend to the original height. The first motor reverses and drives the wheels 19 rearward to the fixed sofa backrest 1. At this point the sofa returns to its original configuration.

The first motor reverses and drives the wheels 19 rearward to the fixed sofa backrest 1. At this point the sofa returns to its original configuration.

If the instruction received is that the third form-changing double bed is received, the first motor rotates forwards to drive the wheels 19 to move forwards, and further drive the separable base 2 to move to a third designated distance, and at the moment, the separable base 2 is close to the fixed sofa backrest 1. And then the first motor stops rotating and is in a self-locking fixed state. The fourth motor and the fifth motor operate to drive the cam 5 to rotate, the cam 5 drives the cam groove 4 to do straight-line ascending motion, the first lifting chair seat 6 and the second lifting chair seat 8 are lifted to the same height as the fixed sofa backrest 1, namely the first designated height, and the fourth motor and the fifth motor stop operating and are in a locking state.

The present embodiment mainly describes the transformation from the original configuration to the first transformation configuration of large table, the second transformation configuration of small table, and the third transformation configuration of double bed. The forms are flexibly changed, and the ductility of the space is greatly improved.

In this embodiment, the conversion between the respective modes will be described in detail with emphasis on the above embodiment.

Specifically, if the first transformation form large-sized passenger table is transformed into the second transformation form small-sized passenger table, the direct current motor push rod telescoping reciprocating motor, namely the second motor 10, reversely rotates to withdraw the connecting rod 11, and further drive the rotary table 3 to rotate to the reset state. The third motor 17 is operated to drive the corresponding first slide bar 12 and second slide bar 13 to make the lifting table 7 rise from the same height as the fixed sofa backrest 1 seat, i.e. the first designated height, to 1.5 times the height of the fixed sofa backrest 1 seat, i.e. the second designated height. The first motor rotates reversely to drive the wheels 19 to retreat from the distance 3.5 times the length of the base of the rotary table from the front side of the fixed sofa backrest 1, namely the first designated distance, to the distance 1.5 times the length of the base of the rotary table from the front side of the fixed sofa backrest 1, namely the second designated distance. The sofa is a second transformation small-sized passenger table.

If the first transformation form large-scale passenger table is transformed into the third transformation form double bed, the direct current motor push rod telescopic reciprocating motor, namely the second motor 10, reversely rotates to withdraw the connecting rod 11, and further drive the rotary table 3 to rotate to the reset state. The first motor rotates reversely to drive the wheels 19 to roll back to the fixed sofa backrest 1, namely, the third designated distance from the first designated distance, which is 3.5 times the length of the base of the rotary table from the front side of the fixed sofa backrest 1, and the sofa is a double bed with a third conversion form.

If the small-sized passenger table in the second transformation form is transformed into the double bed in the third transformation form, the third motor 17 rotates reversely to drive the corresponding first slide bar 12 and second slide bar 13 to make the lifting table top 7 descend from 1.5 times of the height of the fixed sofa backrest 1 seat, namely the second designated height, to the same height as the fixed sofa backrest 1 seat, namely the first designated height, the first motor rotates reversely to drive the wheels 19 to retreat from 1.5 times of the length of the base of the rotary table, namely the second designated distance, away from the front side of the fixed sofa backrest 1 to the third designated distance, namely, away from the fixed sofa backrest 1, and then the sofa form is transformed from the small-sized passenger table into the double bed.

If the sofa is changed from the second shape-changed small-sized passenger table to the first shape-changed large-sized passenger table, the third shape-changed double bed is changed to the first shape-changed large-sized passenger table, and the third shape-changed double bed is changed to the second shape-changed small-sized passenger table, the sofa can reversely run according to the steps.
