[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 , a power module and a driving device of an intelligent sofa, comprising a base 1 and a backrest arranged on the base 1, grooves 2 are provided at both ends of the base 1, an armrest box 3 is movably inserted inside the groove 2, a group of armrest boxes 3 are provided with a mounting groove 4, a through groove connected to the mounting groove 4 is provided on the end surface of the armrest box 3, a rotating plate 5 is rotatably connected inside the through groove, and an airbag 6 is provided on the end surface of the rotating plate 5, and a slide groove 7 connected to the groove 2 is provided on both sides of the bottom of the base 1, and a U-shaped frame 8 is slidably connected inside the two groups of slide grooves 7, and the two ends of the U-shaped frame 8 are respectively fixedly connected to the bottoms of the two groups of armrest boxes 3, a cavity is provided inside the base 1, a power module and an electric push rod 9 electrically connected to the power module are provided inside the cavity, the output shaft of the electric push rod 9 passes through the cavity and is fixedly connected to the U-shaped frame 8, and an inflation device 10 for inflating the airbag 6 and a driving device 11 for driving the rotating plate 5 to rotate are provided inside the groove 2.

[0023] The inflation device 10 includes a sleeve 12 fixedly installed inside the groove 2, and a piston rod 13 inserted into the sleeve 12 is fixedly installed on the inner side of the mounting groove 4. The sleeve 12 is connected to the airbag 6 through an air pipe. The air pipe is a spiral air pipe. The end of the air pipe away from the sleeve 12 passes through the rotating plate 5 and is connected to the airbag 6 through a joint. The air pipe and the airbag 6 can be easily disassembled by the provided joint. When the armrest box 3 is lowered, the piston rod 13 is driven to make the air in the sleeve 12 flow into the interior of the airbag 6.

[0024] The driving device 11 includes a connecting rod 14, both ends of which are pinned to the top of the sleeve 12 and the inner side of the rotating plate 5 respectively. A limit block is provided on the inner wall of the sleeve 12. When the connecting rod 14 rotates ninety degrees, it overlaps with the limit block. When the armrest box 3 descends, the rotating plate 5 is flipped outward under the push of the connecting rod 14 until the rotating plate 5 is placed ninety degrees.

[0025] Through holes 15 are provided at intervals on the back end of the rotating plate 5, and a plurality of groups of bag bags are connected to one side of the rotating plate 5 that is in contact with the airbag 6. The bag bags are arranged inside the through holes 15, and the rotating plate 5 and the airbag 6 are connected by Velcro or buckles. The arranged bag bags are convenient for overlapping with the top of the base 1, so as to support the rotating plate 5, so that there is a certain distance between the rotating plate 5 and the surface of the base 1, thereby preventing the rotating plate 5 and the connecting rod 14 from damaging the surface of the base 1.

[0026] Rollers are rotatably connected to both sides of the inner wall of the groove 2, and the rollers are rotatably connected to the side walls of the armrest box 3. The rollers are used to reduce the resistance when the armrest box 3 is raised or lowered. An accordion protective cover is provided at the bottom of the U-shaped frame 8 and is sleeved on the outside of the slide groove 7. The end of the accordion protective cover away from the U-shaped frame 8 is fixedly connected to the base 1. The accordion protective cover prevents foreign matter from entering the interior of the groove 2.

[0027] Working mode: When working, the power module is connected to an external power source through a wire, and the U-shaped frame 8 is driven to descend through the electric push rod 9, so that the two groups of armrest boxes 3 are lowered. When the armrest box 3 descends, the rotating plate 5 is driven to flip outward under the push of the connecting rod 14 until the rotating plate 5 is placed at ninety degrees. At the same time, when the armrest box 3 descends, the piston rod 13 is driven to make the air in the sleeve 12 flow into the interior of the airbag 6, so that the airbag 6 expands. At this time, the user can lie on the base 1 to rest. The design is more reasonable and more humane.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
