The lifting desk 1 includes lifting desk legs 11, a tabletop 12, and a control panel 13. The tabletop 12 is disposed on the lifting desk legs 11 and is connected to the lifting desk legs 11 in a lifting and sliding manner. The control panel 13 is located at the bottom of the tabletop 12 and controls the lifting of the lifting desk legs 11 to adjust the horizontal position and height of the tabletop 12 by lifting the lifting desk legs 11.

[0036] The intelligent chair 2 includes a base 21, a seat cushion 22, a base frame 23, a backrest 24, and two armrests 25. The seat cushion 22 is fixedly installed on the base 21, the base frame 23 is fixedly installed at the bottom end of the seat cushion 22, the backrest 24 is fixedly installed on the base frame 23, and the backrest 24 can be relatively rotated with respect to the base frame 23. The angle between the backrest 24 and the base 21 is set to D, and the angle between the backrest 24 and the base 21 satisfies 90° < D < 130°. During use, the flipping angle of the backrest 24 can be adjusted according to the user's needs to adjust the backrest 24 to maintain a suitable angle with the base 21, providing the user with a good experience. The two armrests 25 are fixedly installed above both sides of the base frame 23 for the user to rest their hands. The base 21 and the lifting desk legs 11 are driven by two synchronous motors to synchronously lift the base 21 and the lifting desk legs 11.

[0037] Refer to Figure 6-Figure 10 , In order to enable the backrest 24 to be rotatably connected to the base frame 23, an installation hole 231 is formed on the side surface of the base frame 23, and installation members 241 are provided on both sides of the backrest 24. The installation member 241 includes a housing 242, a movable pin 243, and a spring 244. A sliding channel 2421 is formed along the length direction of the housing 242, and the sliding channel 2421 penetrates one end of the housing 242. The movable pin 243 and the spring 244 are installed in the sliding channel 2421, such that the two ends of the spring 244 are respectively abutted against the movable pin 243 and the inner wall end of the housing 242. To prevent the movable pin 243 from completely sliding out of the sliding channel 2421 under the action of the spring 244, a waist-shaped groove 2422 is formed on one side surface of the housing 242, and a limiting rod 245 is formed on the surface of the movable pin 243. The limiting rod 245 on the surface of the movable pin 243 is engaged in the waist-shaped groove 2422 to enable the limiting rod 245 to slide in the waist-shaped groove 2422. When installing the backrest 24 to the base frame 23, the movable pin 243 in the installation member 241 on one side of the backrest 24 is inserted into the installation hole 231 of the base frame 23, and then the movable pin 243 of the installation member 241 on the other side of the backrest 24 is squeezed to be completely hidden into the sliding channel 2421. The movable pin 243 of the installation member 241 on the other side of the backrest 24 is also inserted into the installation hole 231 of the base frame 23 under the action of the spring 244.

[0038] Reference Fig.11 , Fig.12 and Fig.13 The seat cushion 22 is provided with a pressure sensor 3, a vibrator 4 and a control box 5. The seat cushion 22 is provided with a first sponge layer 221, a second sponge layer 222 and a hard layer 223 from the top to the bottom. A wrapping layer 224 is provided on the periphery of the first sponge layer 221 and the second sponge layer 222. The wrapping layer 224 is made of polyester. The wrapping layer 224 made of polyester has the advantages of high strength, good elasticity and good wear resistance. When the user sits on the seat cushion 22, when the surface of the wrapping layer 224 stretches 5% to 6%, it can be almost completely restored.

[0039] The pressure sensor 3 and the vibrator 4 are arranged in the first sponge layer 221, and the surface of the pressure sensor 3 is flush with the upper surface of the first sponge layer 221; the control box 5 is arranged in the hard layer 223, and the control box 5 is electrically connected to the pressure sensor 3 and the vibrator 4 respectively. The control box 5 has a built-in lithium battery 51, a Bluetooth module 52, a charging port 53 and a circuit board 54. The lithium battery 51 and the Bluetooth module 52 are respectively connected to the circuit board 54, and the charging port 53 is connected to the lithium battery 51. The lithium battery 51 is charged through the charging port 53, and the lithium battery 51 supplies power to the circuit board 54. The Bluetooth module 52 in the control box 5 is connected to the control panel 13 in the lifting table 1 by Bluetooth.

[0040] After the user sits on the cushion 22, the pressure sensor 3 senses the pressure exerted by the human body on the surface of the cushion 22. When the pressure sensed by the pressure sensor 3 reaches a predetermined time, the control box 5 will control the vibrator 4 to vibrate. The pressure sensor 3 is used to monitor the length of time the user sits on the cushion 22, and the vibrator 4 vibrates to remind the user of sitting for a long time. The vibration reminder lasts for a total of 30 seconds. When the user stands up within 30 seconds, the system and the user are assumed to have stood up. At the same time, the Bluetooth module 52 in the control box 5 will transmit the information to the control panel 13 of the lifting table 1. The control panel 13 in the lifting table 1 will control the desktop panel 12 to rise to a suitable height, so that the user can stand and work, to avoid the user sitting for a long time.

[0041] Reference Fig.14 , Fig.15 and Fig.16The hard layer 223 is formed by four cross beams 2231 connected by mortise and tenon joints. In order to facilitate the positioning and installation of the base frame 23 on the seat cushion 22, a limiting portion 225 is set on one side of the hard layer 223 to keep the limiting portion 225 and the surface of the hard layer 223 inclined to each other, so that the limiting portion 225 is inclined downward on the side facing away from the hard layer 223. When installing the base frame 23 and the seat cushion 22, the base frame 23 is abutted against the bottom of the seat cushion 22, so that the limiting portion 225 on one side of the hard layer 223 is abutted against one side of the base frame 23. At this time, the limiting portion 225 is located directly below the backrest 24. The setting of the limiting portion 225 makes the installation position between the base frame 23 and the bottom of the seat cushion 22 accurate, and then the seat cushion 22 and the base 21 are fixed by bolts. When the user sits on the seat cushion 22 and leans on the backrest 24 , the human body generates a horizontal backward force on the backrest 24 and the base frame 23 . The setting of the limiting portion 225 on one side of the hard layer 223 limits the base frame 23 , so as to further keep the position between the base frame 23 and the seat cushion 22 stable.

[0042] The specific implementation principle of the embodiment of the present application is: when the user sits on the smart chair 2 to work, the tilt state of the backrest 24 is adjusted according to the user's needs, so that the backrest 24 maintains a suitable angle relative to the cushion 22, so that the user has a good leaning experience. When the user sits on the surface of the cushion 22, the pressure sensor 3 in the cushion 22 senses the pressure exerted by the human body on the surface of the cushion 22. When the pressure sensed by the pressure sensor 3 reaches a predetermined time, the pressure sensor 3 will transmit a signal to the control box 5, and the control box 5 will control the vibrator 4 to issue a vibration reminder. The vibration reminder issued by the vibrator 4 will last for 30 seconds. When the user stands up within 30 seconds of the reminder issued by the vibrator 4, the control box 5 will send a signal to the control panel 13 connected to it through its internal Bluetooth module 52, and the control panel 13 will control the desktop panel 12 to rise to a suitable height, so that the user can stand and work.

[0043] The vibrator 4 vibrates to remind the user of long-term sitting, so as to prevent the user from sitting for a long time at work without knowing it.

[0044] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all protected by the utility model.
