[0072] like Figure 3 As shown, this embodiment also provides a control method applied to the above-mentioned intelligent multifunctional electric-controlled sofa, comprising the following steps:

[0073] When the user initially sits on the sofa backrest 30 , the pressure value measured by the first pressure sensor 1 is a first initial pressure value, and the pressure value measured by the second pressure sensor 2 is a second initial pressure value;

[0074] The measured pressure value of the first pressure sensor 1 exceeds the first initial pressure value by more than a first preset value, and the second initial pressure value exceeds the measured pressure value of the second pressure sensor 2 by more than a second preset value;

[0075] The first angle adjustment mechanism drives the sofa backrest 30 to rotate downward;

[0076] The first initial pressure value exceeds the actual pressure value of the first pressure sensor 1 by more than a third preset value, and the actual pressure value of the second pressure sensor 2 exceeds the second initial pressure value by more than a fourth preset value;

[0077] The first angle adjustment mechanism drives the sofa backrest 30 to rotate upward.

[0078] Specifically, after the user sits down, the control device first records the first initial pressure value measured by the first pressure sensor 1 and the second initial pressure value measured by the second pressure sensor 2 when the user first sits down on the sofa backrest 30; when the user pushes the sofa backrest 30 downward with the upper back, the measured pressure value of the first pressure sensor 1 increases and the measured pressure value of the second pressure sensor 2 decreases. When the measured pressure value of the first pressure sensor 1 exceeds the first initial pressure value by more than a first preset value, and the second initial pressure value exceeds the measured pressure value of the second pressure sensor 2 by more than a second preset value, the first angle adjustment mechanism drives the sofa backrest 30 to rotate downward; when the user lifts the upper back or pushes the sofa backrest 30 downward with the waist, the measured pressure value of the first pressure sensor 1 decreases and the measured pressure value of the second pressure sensor 2 increases. When the first initial pressure value exceeds the measured pressure value of the first pressure sensor 1 by more than a third preset value, and the measured pressure value of the second pressure sensor 2 exceeds the second initial pressure value by more than a fourth preset value, the first angle adjustment mechanism drives the sofa backrest 30 to rotate upward. In summary, the control method of the intelligent multifunctional electric-controlled sofa provided in this embodiment can automatically adjust the angle of the sofa backrest 30 according to the changes in the force exerted by the user's upper back and waist on the sofa backrest 30 to improve the user's comfort. There is no need to manually control the angle adjustment of the sofa backrest 30, and the degree of intelligence is higher.

[0079] Optional, such as Figure 4 As shown, the control method of the intelligent multifunctional electric-controlled sofa further includes the following steps:

[0080] When the user falls asleep, the feed amount of the first angle adjustment mechanism is X and the feed amount of the second angle adjustment mechanism is Y;

[0081] Recording that when the user initially sits on the sofa backrest 30, the temperature sensor 3 measures the user's body temperature as the initial body temperature value;

[0082] The actual body temperature value measured by the temperature sensor 3 is lower than the initial body temperature value by more than a fifth preset value;

[0083] The feed amount of the first angle adjustment mechanism is adjusted to X, and the feed amount of the second angle adjustment mechanism is adjusted to Y.

[0084] Specifically, if the user's body temperature drops by 0.5°C-1°C after falling asleep, the fifth preset value is within the range of 0.5°C-1°C. After the temperature sensor 3 detects that the user has fallen asleep, the feed amount of the first angle adjustment mechanism is controlled to be adjusted to X, and the feed amount of the second angle adjustment mechanism is controlled to be adjusted to Y, so as to automatically rotate the sofa backrest 30 and the leg support assembly plate 40 to the preset angle corresponding to the user's sleeping position, so that the user can maintain a comfortable sleeping posture.

[0085] Optionally, a thirteenth touch key is provided on the touch panel 8. After the user touches the thirteenth touch key, the control device uses the current feed amount of the first angle adjustment mechanism as the new X, and the control device uses the current feed amount of the second angle adjustment mechanism as the new Y, so as to adjust and store the user-defined sleeping posture.
