[0023] The utility model is described in detail below in conjunction with the accompanying drawings.

[0024] Reference Figure 1-Figure 4A lifting smart sofa comprises a bottom plate 1, a supporting frame 2 is fixedly provided on the bottom plate 1, a backrest bag 3 is fixedly provided on the rear side of the supporting frame 2 of the bottom plate 1, armrest bags 4 are fixedly provided on the left and right sides of the supporting frame 2 of the bottom plate 1, a baffle 5 is fixedly provided on the front side of the supporting frame 2, a sliding part 6 is slidably connected to the top of the supporting frame 2, and the sliding part 6 comprises a horizontal plate 601 and a vertical plate 602 fixedly connected to form an L-shaped structure, a slide groove 7 is symmetrically provided on the supporting frame 2, a slide bar (not shown in the figure) that slides with the slide groove 7 is fixedly provided at the bottom of the horizontal plate 601 to limit the horizontal displacement of the horizontal plate 601, a lifting cylinder 8 is fixedly provided at the four inner corners of the supporting frame 2, a lifting block 9 is fixedly provided on the telescopic end of the lifting cylinder 8, a slot 10 for inserting the lifting block 9 is provided at the bottom of the horizontal plate 601, and a seat cushion 11 is provided on the top of the horizontal plate 601.

[0025] Additionally, a pressure sensor 12 is fixedly provided in the slot 10, and the pressure sensor 12 is electrically connected to the lifting cylinder 8. A fixing block 13 for contacting the bottom of the horizontal plate 601 is provided in an annular sleeve on the outer wall of the lifting block 9. The pressure sensor 12 senses whether the lifting block 9 is properly inserted in the slot 10, and then controls the lifting cylinder 8 to start, thereby ensuring safety. At the same time, when the lifting cylinder 8 is started, the fixing block 13 acts on the horizontal plate 601 and pushes the horizontal plate 601 upward, thereby preventing the lifting block 9 from directly acting on the pressure sensor 12 and causing damage.

[0026] An electromagnet 14 is fixedly provided on the side of the baffle 5 facing the vertical plate 602, and a permanent magnet 15 magnetically attracted to the electromagnet 14 is embedded in the vertical plate 602. When the sliding part 6 needs to be pushed back, the electromagnet 14 is controlled to be energized to generate a magnetic attraction force to attract the permanent magnet 15, thereby assisting the user to push the sliding part 6 back. At the same time, after the sliding part 6 is pushed back into place and before the lifting block 9 is inserted into the slot 10, the sliding part 6 can be prevented from sliding on its own. When the lifting block 9 is inserted into the slot 10 and plugged into place, the electromagnet 14 is controlled to be powered off, so that the magnetic attraction force on the permanent magnet 15 is lost, which will not affect the lifting and lowering of the sliding part 6 when it is driven.

[0027] The top of the lifting block 9 is configured to be constricted, so that the lifting block 9 can be smoothly inserted into the slot 10 .

[0028] Buffer blocks 16 that come into contact with the slide bar are fixedly provided at both ends of the inner part of the slide groove 7. The buffer blocks 16 are made of rubber. Therefore, when the sliding part 6 is pulled forward and pushed backward into place, the buffer blocks 16 can provide a shock-absorbing and buffering effect when the slide bar comes into contact with the end of the slide groove 7.

[0029] The bottom of the slide groove 7 is rotatably connected with a plurality of universal balls 17 , and the plurality of universal balls 17 are in contact with the bottom of the slide bar, thereby reducing the friction between the slide bar and the slide groove 7 , and making it easier to push and pull the sliding part 6 .

[0030] A Velcro tape 18 is bonded to the top of the horizontal plate 601, and a Velcro sub-tape (not shown in the figure) that cooperates with the Velcro tape 18 is bonded to the bottom of the seat cushion 11. The seat cushion 11 can be disassembled and assembled by the Velcro tape 18 and the Velcro sub-tape, so that the seat cushion 11 can be quickly removed during maintenance, which is convenient for pushing and pulling the sliding part 6.

[0031] Working principle: When the smart sofa is in normal use, the smooth lifting function of the sofa can be achieved by controlling the lifting of the four lifting cylinders 8, and through the shielding of the vertical plate 602 and the baffle 5, there will be no problem of internal components being exposed on the front side of the sofa. When maintenance is needed, first control the lifting cylinder 8 to contract and drive the jacking block 9 to exit the slot 10. At this time, the sliding part 6 can be pulled forward to expose the lifting cylinder 8 located inside the supporting frame 2, which is convenient for maintenance and replacement. After the maintenance is completed, push the sliding part 6 back to its original position again. At this time, the slot 10 at the bottom of the cross plate 601 is aligned with the jacking block 9 again, control the lifting cylinder 8 to extend and insert the jacking block 9 into the slot 10, then the sliding part 6 can no longer move horizontally, and then control the lifting cylinder 8 to continue to extend to realize the lifting of the sofa, thereby meeting the use needs of different users.

[0032] The lifting cylinder 8, electromagnet 14 and pressure sensor 12 of the utility model are all electrically connected to the controller of the smart sofa to achieve regulation and coordination. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0033] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
