[0064] The intelligent sofa of the present invention has four forms, namely, an original form sofa, a first transformation form large guest table, a second transformation form small guest table, and a third transformation form double bed.

[0065] When a transformation instruction is received, the intelligent control module 22 determines which form it is.

[0066] If it is the first transformation form, the first motor rotates forward, driving the wheel 19 to move forward, and then the detachable base 2 is separated from the fixed sofa backrest 1. When it moves to the first specified distance, the detachable base 2 is located in front of the fixed sofa backrest 1 by 3.5 times the length of the base of the rotating table 3. The first motor stops rotating and is in a locked state, and the sofa is in a fixed state. Subsequently, the third motor 17 runs, driving the screw rod 16 to rotate forward through the bevel gear 18, and then driving the screw nut 15 to move along the direction of the screw rod 16. The screw nut 15 drives the first slide bar 12 connected thereto to move, and the first slide bar 12 is connected to the second slide bar 13 through the auxiliary connecting rod 14, thereby driving the second slide bar 13 to do the same movement. The lifting table 7 is raised to the first specified height, which is the same height as the fixed sofa backrest 1 seat. The fourth motor and the fifth motor run, driving the cam 5 to rotate, and then the cam 5 drives the cam slot 4 to do a linear upward movement, and the first lifting seat surface 6 and the second lifting seat surface 8 are raised to the same height as the fixed sofa backrest 1 seat, that is, the first specified height, and then stop running and lock. The second motor 10 is running, and the second motor is a DC motor push rod telescopic reciprocating motor. The connecting rod 11 is extended to increase the angle between the rotating table 3 and the fixed sofa backrest 1, and then the rotating table 3 moves in a quarter arc track. When the bottom surface of the rotating table 3 is flush with the ground, the second motor 10 stops running, and the sofa is transformed from the original form to the first transformed form of a large guest table. If it is necessary to restore to the original form, enter the reset command, the DC motor push rod telescopic reciprocating second motor 10 reverses, retracts the connecting rod 11, and then drives the rotating table 3 to rotate to the reset state. The fourth motor and the fifth motor cancel the lock and continue to rotate, driving the cam 5 to rotate, and the cam 5 drives the cam groove 4 to make a linear downward movement, and the first lifting seat surface 6 and the second lifting seat surface 8 are lowered to the original height. Subsequently, the third motor 17 reverses and drives the screw rod 16 to rotate in the opposite direction through the bevel gear 18. The screw rod 16 reverses and drives the screw 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 to the screw nut 15 move in the opposite direction, driving the lifting table 7 to make a linear downward movement to the original height. The first motor rotates in the reverse direction, driving the wheel 19 to move backward to fix the sofa backrest 1. At this time, the sofa returns to its original state.

[0067] If the instruction received is a small guest table of the second transformation form, the first motor rotates forward, driving the wheel 19 to move forward, and then driving the detachable base 2 to move to the second specified distance. At this time, the detachable base 2 is located in front of the fixed sofa backrest 1, 1.5 times the length of the rotating table base. Then the first motor stops rotating and is in a self-locking fixed state. The third motor 17 runs, driving the screw rod 16 to rotate forward through the bevel gear 18, and then driving the screw nut 15 to move along the direction of the screw rod 16. The screw nut 15 drives the first slide bar 12 fixed thereto to move, and the first slide bar 12 is connected to the second slide bar 13 through the auxiliary connecting rod 14, and then drives the second slide bar 13 to do the same movement, raising the lifting table top 7 to the second specified height. At this time, the height of the lifting table top 7 is 1.5 times the height of the fixed sofa backrest 1 seat. Then the fourth motor and the fifth motor are operated, driving the cam 5 to rotate, and then the cam 5 drives the cam slot 4 to move straight up, and after the first lifting seat surface 6 and the second lifting seat surface 8 are raised to the same height as the fixed sofa backrest 1 seat, that is, the first specified height, the fourth motor and the fifth motor stop and are in a locked state, and the sofa is transformed from the original form to the second transformed form of a small guest table. If it is necessary to restore to the original form, the reset command is input, the fourth motor and the fifth motor cancel the lock, continue to rotate, and then drive the cam 5 to rotate, and the cam 5 drives the cam slot 4 to move straight down, and the first lifting seat surface 6 and the second lifting seat surface 8 are lowered to the original height. Then, the third motor 17 reverses and drives the screw rod 16 to rotate in the opposite direction through the bevel gear 18, and the screw rod 16 reverses and drives the screw 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 to the screw nut 15 move in the opposite direction, driving the lifting table 7 to move straight down to the original height. The first motor reverses and drives the wheel 19 to move backward to the fixed sofa backrest 1. At this time, the sofa returns to its original form.

[0068] If the instruction received is the third transformation form double bed, the first motor rotates forward, driving the wheel 19 to move forward, and then driving the detachable base 2 to move to the third specified distance, at which time the detachable base 2 is close to the fixed sofa backrest 1. After that, the first motor stops rotating and is in a self-locking fixed state. The fourth motor and the fifth motor operate, driving the cam 5 to rotate, and then the cam 5 drives the cam groove 4 to move linearly upward, raising the first lifting seat surface 6 and the second lifting seat surface 8 to the same height as the fixed sofa backrest 1 seat, that is, the first specified height, and the fourth motor and the fifth motor stop operating and are in a locked state. Then the third motor 17 operates, driving the screw 16 to rotate forward through the bevel gear 18, and then driving the screw nut 15 to move along the direction of the screw 16, and the screw nut 15 drives the first slide bar 12 fixed thereto to move, and the first slide bar 12 is connected to the second slide bar 13 through the auxiliary connecting rod 14, and then drives the second slide bar 13 to do the same movement. Then the lifting tabletop 7 is raised to the same height as the fixed sofa backrest 1, i.e. the first designated height. At this time, the third motor 17 and the fourth motor 5 are all in a fixed self-locking state, thereby ensuring the stability of the double bed in the third transformed form. If the sofa needs to be restored to its original state, a reset command is input, and the third motor 17 cancels the locking state and reverses, so that the lifting tabletop 7 drops to its original height. The fourth motor and the fifth motor also cancel the locking state and continue to rotate, driving the first lifting seat surface 6 and the second lifting seat surface 8 to make a straight line downward movement to the original height. The first motor reverses and drives the wheel 19 to move backward to the fixed sofa backrest 1, and the sofa returns to its original form.

[0069] This example mainly introduces the transformation from the original form to the first transformation form of a large guest table, the second transformation form of a small guest table, and the third transformation form of a double bed. The flexible transformation between the various forms greatly improves the ductility of the space.

[0070] Based on the above embodiment, this embodiment focuses on describing in detail the transformation between various forms.

[0071] Specifically, if the large guest table in the first transformation form is transformed into the small guest table in the second transformation form, the DC motor push rod telescopic reciprocating motor, that is, the second motor 10 is reversed, the connecting rod 11 is retracted, and then the rotating table 3 is driven to rotate to the reset state. The third motor 17 is operated, driving the corresponding first slide bar 12 and second slide bar 13 to make the lifting table top 7 rise from the same height as the fixed sofa backrest 1 seat, that is, the first designated height, to 1.5 times the height of the fixed sofa backrest 1 seat, that is, the second designated height. The first motor reverses and drives the wheel 19 to retreat from the front side of the fixed sofa backrest 1 3.5 times the length of the rotating table base, that is, the first designated distance, to the front side of the fixed sofa backrest 1 1.5 times the length of the rotating table base, that is, the second designated distance. At this time, the sofa is a small guest table in the second transformation form.

[0072] If the large guest table in the first transformation form is transformed into the double bed in the third transformation form, the DC motor push rod telescopic reciprocating motor, that is, the second motor 10, is reversed to retract the connecting rod 11, thereby driving the rotating table 3 to rotate to the reset state. The first motor is reversed to drive the wheel 19 to retreat from the front side of the fixed sofa backrest 1, which is 3.5 times the length of the rotating table base, that is, the first designated distance, to the fixed sofa backrest 1, that is, the third designated distance. At this time, the sofa is the third transformation form double bed.

[0073] If the small guest table is transformed from the second transformation form to the third transformation form of a double bed, the third motor 17 reverses, driving the corresponding first slide bar 12 and second slide bar 13 to make the lifting table top 7 drop from 1.5 times the fixed sofa back 1 seat height, i.e. the second designated height, to the same height as the fixed sofa back 1 seat, i.e. the first designated height. The first motor reverses and drives the wheels 19 to retreat from 1.5 times the length of the rotating table base from the front side of the fixed sofa back 1, i.e. the second designated distance, to close to the fixed sofa back 1, i.e. the third designated distance. At this time, the sofa shape changes from a small guest table to a double bed.

[0074] If the sofa is transformed from the second transformation form small guest table to the first transformation form large guest table, the third transformation form double bed is transformed to the first transformation form large guest table, and the third transformation form double bed is transformed to the second transformation form small guest table, the above steps can be reversed.

[0075] This embodiment is based on the above two embodiments and focuses on a detailed description of the auxiliary function.

[0076] Auxiliary function 1

[0077] Hidden cabinet 9 function, the present invention designs a hidden cabinet 9 function, the specific implementation of this function can be divided into viewing and access. When the user needs to view the contents of the hidden cabinet 9, after entering the password on the display screen, the items in the hidden cabinet 9 can be viewed through the camera. If the user needs to access items, the function 1 can be selected through the function application of the intelligent control module 22. At this time, the first motor rotates to bring out the detachable base 2, and then the fourth motor and the fifth motor operate to raise the cam slot 4.
