The electrical control principle of an embodiment of the present invention is shown in fig. 3, and in an embodiment of the present invention, when a user sits on the seat 2, the seat surface pressure sensor 23 receives the pressure of the human body to generate a pressure signal, which forms the sitting information of the user. Meanwhile, when the user sits on the seat 2, the leg of the user presses the seat rim pressure sensor 24. The pressure of the legs of the user on the front edge of the seat surface is directly related to the sitting comfort of the user, the height of the seat surface 21 is adjusted according to the pressure detected by the seat edge pressure sensor 24, the height of the seat surface 21 is different, the pressure of the legs of the user on the front edge of the seat surface 21 is also different under the condition that the feet of the user land, and the pressure of the legs of the user on the front edge of the seat surface 21 can be adjusted by adjusting the height of the seat surface 21, so that the user is in a comfortable sitting state. Therefore, when users with different heights sit on the seat 2, the seat surface 21 can be automatically adjusted to the height with higher sitting comfort level, and the use comfort level of the intelligent lifting table and chair is ensured. When the height of the seat 21 is adjusted to be in place, the second controller 26 transmits the adjusted height information of the seat 21 and the seating information transmitted from the seat pressure sensor 23 to the second wireless communication unit 25, and transmits the information to the first wireless communication unit 13 through the wireless connection between the second wireless communication unit 25 and the first wireless communication unit 13; after receiving the height information and the sitting information of the seat 21 transmitted from the first wireless communication unit 13, the first controller 14 sends a control command to control the lifting legs 12 to descend, so that the height of the tabletop 11 is reduced to a height corresponding to the height of the seat 21, and the sitting comfort of the user is ensured. On the contrary, when the user leaves the seat 2, the pressure of the human body on the seat surface pressure sensor 23 disappears, and the pressure signal generated by the seat surface pressure sensor 23 also disappears, which forms the information of the user leaving the seat. The off-seat information is transmitted to the first controller 14 along the same path, and the first controller 14 sends a control command to control the lifting legs 12 to rise, so that the height of the tabletop 11 rises to a height suitable for the standing posture of the user. The sedentary reminding function can also be realized by recording the sitting time through the second controller 26 or the first controller 14 and giving a reminding message when the sitting duration reaches a set value.

In some embodiments of the invention, as shown in fig. 1 to 3, the table 1 is also provided with a control panel 15 for inputting control information. The manipulation panel 15 is connected to the first controller 14 through a signal line.

Pressing the storage button 155 starts the storage mode of the first controller 14, and at this time, pressing the high setting button 153 stores the current height of the tabletop 11 as the upper height of the tabletop; when the lower setting button 154 is pressed, the current height of the table top 11 is stored as the lower height of the table top. The storage mode of the first controller 14 is exited by pressing the storage button 155, and the high setting button 153 or the low setting button 154 is pressed again without any effect, so that the upper height of the table top or the lower height of the table top is prevented from being accidentally modified. The control panel 15 may further be provided with a liquid crystal screen 159 for displaying information such as the height of the desktop 11, the operating status of the first controller 14, and the status of the control panel 15.

As a specific embodiment of the present invention, as shown in fig. 2, a manual button 156 is further disposed on the control panel 15, the manual button 156 is pressed, the first controller 14 controls the height adjustment mode of the tabletop 11 of the intelligent lifting table and chair of the present invention to switch between a manual mode and an automatic mode, when the height adjustment mode of the tabletop 11 is the manual mode, the control function of the trigger signal of the seat pressure sensor 23 on the lifting legs 12 is turned off, at this time, the height of the tabletop 11 does not automatically lift with the sitting of the user, and only the height adjustment can be performed through the tabletop lift button 151 and the tabletop lift button 152.

As an embodiment of the present invention, as shown in fig. 2, a seat up button 157 and a seat down button 158 are further provided on the control panel 15. When the seat-up button 157 is pressed, the first controller 14 receives the trigger signal of the seat-up button 157, and controls the first wireless communication unit 13 to send the invalid signal to the second wireless communication unit 25, and then to the second controller 26, and controls the lifting seat 22 to lift up, so as to drive the seat 21 to lift up.

In some embodiments of the present invention, as shown in fig. 1 and 3, when the seat surface pressure sensor 23 detects the seating pressure of a human body, that is, when a user sits on the seat 2, the leg of the user presses the seat edge pressure sensor 24, and in the case where the foot of the user lands on the ground, the pressure of the leg of the user against the front edge of the seat surface increases as the height of the seat surface 21 increases; when the user's legs contact the front edge of the seat 21, the pressure of the user's legs against the front edge of the seat decreases as the height of the seat 21 decreases. When the pressure of the legs of the user on the front edge of the seat surface is in a certain proportion to the pressure of the user on the middle part of the seat surface, the user feels most comfortable when sitting. Therefore, the ratio of the pressure value detected by the seat edge pressure sensor 24 to the pressure value detected by the seat surface pressure sensor 23 when the user sits comfortably can be selected as a set value, when the user sits on the seat 2, the second controller 26 can obtain the pressure of the leg of the user detected by the seat edge pressure sensor 24 to the front edge of the seat surface, compare the ratio of the pressure to the pressure detected by the seat surface pressure sensor 23 with the set value, and control the seat surface 21 to descend when the ratio is greater than the set value; when the ratio is smaller than the set value, the seat 21 is controlled to rise, so that the height of the seat 21 can be automatically adjusted to a height suitable for comfortable seating of different users. The second controller 26 may also limit the conditions for controlling the lifting and lowering of the seat surface 21 by the pressure detected by the seat rim pressure sensor 24. If the pressure value detected by the seat edge pressure sensor 24 changes continuously, or the pressure value detected by the seat edge pressure sensor 24 exceeds a certain proportion of the pressure value detected by the seat surface pressure sensor 23, for example, 70%, the height of the seat surface 21 does not automatically rise or fall along with the change of the ratio of the pressure value detected by the seat edge pressure sensor 24 to the pressure value detected by the seat surface pressure sensor 23, so that the wrong adjustment of the height of the seat surface 21 caused by special conditions that the user tilts legs, the legs shake or the sitting position is too close to the front edge of the seat surface 21 can be prevented.

The second controller 26 is also capable of storing the height of the seat 2 after the seat 21 is adjusted in position and maintaining the height of the seat 21 at the height after the user is out of the seat. When the user sits again, the second controller 26 receives the detection values of the seat surface pressure sensor 23 and the seat edge pressure sensor 24, and determines whether or not to adjust the height of the seat surface 21. Thus, when the same user sits intermittently, the height adjustment of the seat surface 21 can be reduced, the use is convenient, and the power consumption of the chair power module 29 can be reduced.

As an embodiment of the present invention, as shown in fig. 3, a chair height adjusting button 27 and a chair height manual button 28 are provided on the chair 2. The chair height adjusting button 27 and the chair height manual button 28 may be provided under the armrest of the seat 2, and the chair height adjusting button 27 may further include a chair height raising button and a chair height lowering button. The chair height up button, the chair height down button and the chair height manual button 28 are all electrically connected to the second controller 26. When the chair height rising button is pressed, the second controller 26 can be triggered to control the rising of the lifting seat 22 so as to drive the chair surface 21 to rise in height; when the chair height descending button is pressed, the second controller 26 can be triggered to control the ascending and descending seat 22 to descend so as to drive the chair seat 21 to descend in height. The mode of the second controller 26 for controlling the lifting of the lifting seat 22 can be switched to an automatic control mode or a manual control mode by pressing the chair height manual control button 28. In the automatic control mode, the second controller 26 can automatically control the elevation of the elevation base 22 according to the pressure detected by the seat rim pressure sensor 24; in the manual control mode, the lifting of the lifting seat 22 is no longer influenced by the seat rim pressure sensor 24, but is controlled only by the seat height adjustment button 27.

In some embodiments of the present invention, as shown in fig. 1, the seat pressure sensor 23 includes a first seat sensor 231, a second seat sensor 232, a third seat sensor 233, and a fourth seat sensor 234 arranged in a rectangular shape in the middle of the seat 21, and two long sides of the rectangular shape are arranged right and left and two short sides are arranged front and back, and the first seat sensor 231, the second seat sensor 232, the third seat sensor 233, and the fourth seat sensor 234 are electrically connected to the second controller 26, and have transmitted the detected pressure signal to the second controller 26. When the seat 21 is used, the buttocks of the user can press the first seat sensor 231, the second seat sensor 232, the third seat sensor 233 and the fourth seat sensor 234 at the same time, and the pressure detected by the first seat sensor 231, the second seat sensor 232, the third seat sensor 233 and the fourth seat sensor 234 is not greatly different. When the sitting posture is not correct, the weight of the user is concentrated on the partial seat sensors, so that the pressure detected by the first seat sensor 231, the second seat sensor 232, the third seat sensor 233 and the fourth seat sensor 234 is greatly different, and even the partial seat sensors cannot detect the sitting pressure of the user. At this time, the second controller 26 can send out the sitting posture correction prompt message to prompt the user to adjust the sitting posture.

As an embodiment of the present invention, as shown in fig. 3, the table 1 is further provided with a voice prompt module 16. The voice prompt module 16 is electrically connected to the first controller 14, when the difference between the pressure values detected by the first seat sensor 231, the second seat sensor 232, the third seat sensor 233 and the fourth seat sensor 234 exceeds a set value, the second controller 26 transmits the information that the sitting posture is incorrect to the first controller 14 through the wireless communication unit, and the first controller 14 controls the voice prompt module 16 to give a voice prompt that the sitting posture is incorrect.
