[0013] (III) Beneficial effects

[0014] Compared with the prior art, the present invention provides a sofa based on smart furniture sensor technology, which has the following beneficial effects:

[0015] 1. The sofa based on the intelligent furniture sensor technology is provided with a pressing block. When people sit on the sponge board and lean their backs on the sponge block, the sponge block is deformed to make the back of the person fit with the pressing blocks on the two rotating rods inside the massage groove. At this time, the sensing device on the board starts the rotating motor on the corresponding side inside the power chamber, and the output shaft rotates to drive the linkage gear to rotate. The rotation of the linkage gear drives the two rotating gears to rotate. The rotation of the two rotating gears drives the two rotating rods inside the massage groove to rotate. The rotation of the two rotating rods drives the four rotating rings to rotate. When the rotating ring rotates, it drives the pressing blocks on the four connecting rods on the rotating ring to squeeze the acupuncture points on the back of people in turn, so that the back of people can be relaxed, so as to relieve the fatigue generated by people at work and improve the practicality of the sofa.

[0016] 2. The sofa based on smart furniture sensor technology is provided with limit blocks. When people squeeze the sponge block with their backs, the two support blocks inside the massage groove move downward due to the squeezing force until the two support blocks are close to one side wall inside the massage groove and contact the two limit blocks, and then stop moving backward. This avoids the rotating device inside the massage groove from being damaged by excessive squeezing force during use, thereby achieving the effect of protecting the rotating device inside the massage groove and improving the service life of the product.

[0017] 3. The sofa based on smart furniture sensor technology is provided with a bearing block. In daily use, when people place their arms on the bearing blocks on the support plate, the bearing blocks are subjected to gravity to cause the deformation springs inside the deformation grooves to deform, thereby driving the bearing blocks to move downward into the deformation grooves. Bearing blocks at different positions are subjected to different forces, resulting in different degrees of entry into the deformation grooves. The shape of the bearing blocks can be adjusted according to the state of people's arms, thereby improving the comfort of the sofa when in use.

[0018] 4. The sofa based on smart furniture sensor technology is provided with airbags. When people sit on the sponge board, the airbags inside the buffer groove are deformed, which cushions the force of people sitting down and improves the softness of the sponge board, thereby improving the comfort of the sofa when in use. When people stand up, the airbags restore their deformation and drive the sponge board upward, thereby avoiding the problem of the surface deformation of the sofa affecting the appearance due to long-term use and improving the service life of the sofa.

[0019] 5. The sofa based on the smart furniture sensor technology is provided with rollers. When the bottom of the sofa needs to be cleaned, the rollers inside the fixed groove can be driven to roll by pushing the two support plates, so as to achieve the effect of quickly moving the position of the sofa and improve the practicality of the sofa.

[0034] How it works

[0035] When in use, when people sit on the sponge board 4 and lean their backs on the sponge block 13, the sponge block 13 is deformed so that the person's back fits against the pressing blocks 18 on the two rotating rods 15 inside the massage groove 14. At this time, the sensing device 31 on the back plate 12 starts the rotating motor 24 on the corresponding side of the power chamber 23, and the output shaft 25 rotates to drive the linkage gear 27 to rotate. The rotation of the linkage gear 27 drives the two rotating gears 26 to rotate. The rotation of the two rotating gears 26 drives the two rotating rods 15 inside the massage groove 14 to rotate. The rotation of the two rotating rods 15 drives the four rotating rings 16 to rotate. When the rotating ring 16 rotates, it drives the pressing blocks 18 on the four connecting rods 17 on the rotating ring 16 to squeeze the acupuncture points on the back of people in turn, so that people's backs can be relaxed, achieving the effect of relieving people's fatigue at work, and improving the practicality of the sofa.

[0036] When people squeeze the sponge block 13 with their backs, the two support blocks 30 inside the massage groove 14 move downward due to the squeezing force until the two support blocks 30 are close to one side wall inside the massage groove 14 and contact the two limit blocks 28 and then stop moving backwards, so as to avoid the rotating device inside the massage groove 14 being damaged by excessive squeezing force during use, thereby achieving the effect of protecting the rotating device inside the massage groove 14 and improving the service life of the product.

[0037] In daily use, when people's arms are placed on the supporting block 7 on the supporting plate 5, the supporting block 7 is subjected to gravity to cause the deformation spring 9 inside the deformation groove 8 to deform, driving the supporting block 7 to move downward into the deformation groove 8. The supporting blocks 7 at different positions are subjected to different forces, resulting in different degrees of entry into the deformation groove 8. The shape of the supporting block 7 can be adjusted according to the state of people's arms, thereby improving the comfort of the sofa when in use.

[0038] When people sit on the sponge board 4, the airbag 3 inside the buffer groove 2 is deformed, which cushions the force of people sitting down and improves the softness of the sponge board 4, thereby improving the comfort of the sofa when in use. When people stand up, the airbag 3 recovers the deformation and drives the sponge board 4 upward, thereby avoiding the problem of the surface deformation of the sofa affecting the appearance due to long-term use and improving the service life of the sofa.

[0039] When the bottom of the sofa needs to be cleaned, the two support plates 5 can be pushed to drive the rollers 11 inside the fixing grooves 10 to roll, so as to achieve the effect of quickly moving the position of the sofa and improve the practicality of the sofa.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
