DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0021] A smart sofa with a lifting function comprises a base 1, a backrest 2 arranged at the rear side of the base 1 and armrests 3 arranged at both sides of the base 1, and a plurality of groups of cushions 4 are arranged in parallel on the top of the base 1 between the backrest 2 and the armrests 3:

[0022] The top of the base 1 is provided with a strip groove 5 for accommodating multiple groups of cushions 4, a mounting cavity 6 is provided in the base 1 below the strip groove 5, a lifting mechanism 7 is provided in the strip groove 5 below the cushion 4, the bottom end of the lifting mechanism 7 extends into the mounting cavity 6, and a driving mechanism 8 for driving the multiple groups of lifting mechanisms 7 to rotate is provided in the mounting cavity 6;

[0023] The lifting mechanism 7 includes a driving shaft 71 fixed on the inner bottom wall of the mounting cavity 6 by a bearing, a sprocket I72 is arranged on the driving shaft 71, the driving shaft 71 is connected to the mounting plate 73 at the bottom of the strip groove 5, a screw tube I74 is arranged on the top of the mounting plate 73, a screw tube II75 screwed thereto is arranged on the outer sleeve of the screw tube I74, a circular plate 76 is arranged on the top of the screw tube II75, a connecting shaft 77 embedded in the bottom of the cushion 4 is arranged on the top of the circular plate 76, and the circular plate 7 6 A plurality of groups of arc grooves I78 are arranged in the circumferential direction of the top, a metal plate 79 is fixed in the arc groove I78 through a rotating shaft 710, an arc groove II711 corresponding to the arc groove I78 is arranged at the bottom of the seat cushion 4, an electromagnet 712 is arranged in the arc groove II711, the length of the arc groove II711 is greater than the length of the arc groove I78, and the electromagnet 712 generates a magnetic attraction force to drive the metal plate 79 to rotate around the rotating shaft 710 as the center and slide into the corresponding arc groove II711;

[0024] The driving mechanism 8 includes a circle of chain 81 which is sleeved on multiple groups of sprockets I72. A sprocket II82 which meshes with the chain 81 is also arranged in the installation cavity 6. The sprocket II82 is driven by a motor 83.

[0025] In this embodiment, the bottom of the seat cushion 4 is provided with a bearing sleeved on the connecting shaft 77, the top of the circular plate 76 is provided with an annular seat I9 that abuts against the bottom end face of the seat cushion 4, and the vertical section of the top of the side wall of the annular seat I9 is ​​a semicircular structure, and the bottom of the mounting plate 73 is provided with an annular seat II10 that abuts against the inner bottom wall of the strip groove 5, and the vertical section of the bottom of the side wall of the annular seat II10 is a semicircular structure.

[0026] like Figure 2 , 3 As shown in 4, sprockets III12 are arranged on both sides of the installation cavity 6 to support the chain 81 and mesh with it, and a vertical rod 13 is arranged on the sprocket III12. Both ends of the vertical rod 13 are fixed to the upper and lower side walls of the installation cavity 6 through bearings. A limiting rod 13 is arranged in the installation cavity 6 on the front and rear sides of the chain 81. The chain 81 is clamped by the limiting rod 13 so that the chain 81 is tightly attached to and meshed with the sprocket I72, the sprocket II82 and the sprocket III12.

[0027] In this embodiment, the armrest 3 is provided with a display screen and control buttons, and the display screen and control buttons are connected to the controller, and the motor 83 and the electromagnet 712 are connected to the controller.

[0028] In this embodiment, the screw tube I74 is fixedly connected to the mounting plate 73, the diameter of the mounting plate 73 is larger than the diameter of the screw tube II75, the connecting shaft 77, the circular plate 76, the screw tube II75, the screw tube I74, the mounting plate 73 and the driving shaft 71 are coaxially arranged, and the middle of the bottom inner part of the circular plate 76 is connected to the middle of the top of the mounting plate 73 through a telescopic rod, and the maximum length of the telescopic rod after stretching is less than the sum of the lengths between the screw tube I74 and the screw tube II75.

[0029] When it is necessary to adjust the height of a group of seat cushions 4 during use, the electromagnet 712 at the bottom of the seat cushion 4 is controlled by the button and the controller, so that the electromagnet 712 at the bottom is energized to generate magnetic attraction, thereby driving the metal plate 79 in the arc groove I78 directly below it to rotate with the rotating shaft 710 as the center. At the same time, the rotated metal plate 79 slides into the arc groove II711 and is magnetically connected to the electromagnet 12. Then, when the motor 83 drives the chain 81 to rotate through the sprocket II82, the chain 81 drives the drive shaft 71, the mounting plate 73, the screw I74, the screw II75 and the circular plate 76 through the sprocket I72 to drive the connecting shaft 77 to rotate on the bearing at the bottom of the seat cushion 4. Since the top of the metal plate 79 directly below the seat cushion 4 needs to be adjusted, it slides into the arc groove II711. In this process, the adjacent seat cushions 4 are stuck to each other to prevent the seat cushions 4 from rotating together with the circular plate 76 and other components, so that the seat cushion 4 that needs to be adjusted will only move up and down between the two adjacent groups of seat cushions 4. At this time, the seat cushion 4 clamps the metal plate 79 through the arc groove II711, and the metal plate 79 clamps the side wall of the arc groove I78 on the top of the circular plate 76, preventing the circular plate 76 and the screw tube II75 below the seat cushion 4 that needs to be adjusted from being driven by the corresponding screw tube I74 to rotate together. At this time, the screw tube I74 rotating in the screw tube II75 will drive the screw tube II75 to drive the circular plate 76 and the seat cushion 4 directly above it to move up and down, thereby adjusting its height to meet the use requirements. At this time, the height of the seat cushions 4 around it will not be adjusted up and down under the influence of the driving mechanism 8;

[0030] When the height adjustment of the seat cushion 4 is completed, it is only necessary to cut off the power to the electromagnet 712 at the bottom thereof. Then, the metal plate 79 located in the arc groove II711 at the bottom thereof slides into the arc groove I78 with the rotating shaft 710 as the center under the influence of gravity. The subsequent rotation of the driving mechanism 8 will not drive the seat cushion 4 to adjust its height. In the above process, the bottom end of the seat cushion 4 after adjustment is always located between the two groups of seat cushions 4 on both sides thereof, or its bottom end is always located in the strip groove 5, so as to support the bottom end of the seat cushion 4 in the above manner to prevent it from rotating together with the circular plate 76 and other components. When it is necessary to adjust the height of other seat cushions 4, it is only necessary to adjust the height of the seat cushion 4. The electromagnet 712 at the bottom is operated to magnetically attract the metal plate 79 in the arc groove I78 to the electromagnet 712 in the arc groove II711, and then the working driving mechanism 8 can drive the seat cushion 4 to adjust its height through the corresponding lifting mechanism 7. At the same time, it is only necessary to cut off the power of the electromagnet 712, so that the metal plate 79 slides into the corresponding arc groove I78 under the influence of gravity. At this time, the rotating driving mechanism 8 will neither drive the seat cushion 4 to adjust its height, so that the heights of several seat cushions 4 can be adjusted one by one in the above manner to make them suitable for the use requirements of different groups of people, thereby improving their scope of application.

[0031] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
