Fig. 1 shows an adjustment control system for an electric seat, which includes a first pressure sensing unit 1, a second pressure sensing unit 2, a control panel 3, a signal processing unit, a motor driving unit, and a motor executing unit 5.
First pressure sensing unit 1: the method comprises the steps that the gravity on a seat cushion of the seat is collected, and the collected pressure or switching value information is transmitted to a signal processing unit and used for judging whether a person sits on the seat or whether the stress borne by the seat reaches a set value;
the second pressure sensing unit 2: the method comprises the steps that the gravity on the backrest of the seat is collected, the collected pressure or switching value information is transmitted to a signal processing unit, and a reasonable installation height is set and used for judging whether a person sitting on the seat is an adult or whether the person leans against the backrest of the seat;
control panel 3: usually, the interface is a hand controller or a mobile terminal APP, and transmits a user operation instruction to the signal processing unit;
a signal processing unit: the core of the signal processing unit is an MCU (microprogrammed control Unit), signals and instructions of the first pressure sensing unit 1, the second pressure sensing unit 2 and the control panel unit are received and transmitted to the MCU, the MCU processes the signals and the instructions through an internal program and then outputs control signals to the motor driving unit;
a motor drive unit: amplifying a control signal from the signal processing unit to drive the motor execution unit;
the motor execution unit 4: the motor driving unit is used for driving the motor inside the seat and converting electric energy into mechanical energy to realize the adjustment of the seat posture.
The signal processing unit can realize the following control through the MCU through the information processing judgment of the first pressure sensing unit 1 and the second pressure sensing unit 2:
1, when the pressure on the first pressure sensing unit 1 is detected to be lower than a set value, the MCU judges that a user does not sit on the seat or only an infant sits on the seat, and the MCU does not execute the instruction of the control panel unit;
2, when the pressure on the first pressure sensing unit 1 is detected to be higher than the set value and the pressure on the second pressure sensing unit 2 is detected to be lower than the set value (the user is judged not to be tightly leaned against the backrest or only the infant is seated on the backrest), the MCU does not execute the instruction of the control panel unit;
and 3, when the pressure on the first pressure sensing unit 1 and the second pressure sensing unit 2 is lower than the set value and lasts for a period of time (generally, several minutes to several tens of minutes), the seat automatically returns to the initial state.
As will be described below in connection with an example of use of a single sofa, as shown in figure 2,
the first pressure sensing unit 1 is a hip pressure sensor, such as a gravity push-button switch or an air bag pressure switch. Embedded under the covering of the cushion sofa;

the control panel 3, called a hand controller, is usually installed on the side of the sofa armrest and can be hand-held.
And the control box 4 is internally provided with a signal processing unit and a motor driving unit.
The motor execution unit 5 is called a linear driver or a linear push rod, and the telescopic motion of the transmission part of the motor execution unit realizes the posture adjustment of the seat through the seat frame transmission mechanism.
Example 1:
in the design of the functional sofa, the first pressure sensing unit 1 is placed under a sofa cushion, the second pressure sensing unit 2 is placed under a sofa backrest, the control panel 3 (also can be controlled by a handheld hand controller or a mobile terminal APP) is arranged at a sofa armrest, the control panel 3, the first pressure sensing unit 1 and the second pressure sensing unit 2 are connected with the control box 4, the control box 4 contains a signal processing unit and a motor driving unit, and the motor driving unit drives the motor executing unit 5 (for example, a linear push rod).
The control is realized by the programming of the MCU in the signal processing unit:
1, when no person sits on the sofa or only an infant sits on the sofa, the pressure on the first pressure sensing unit 1 is lower than a set value, and at the moment, the MCU does not execute the instruction of the control panel unit, so that the sofa does not act. So as to avoid the safety risk caused by the operation of the sofa by children;
2, when the user does not lean against the backrest or only the child sits on the first pressure sensing unit 1, the pressure on the first pressure sensing unit 1 is higher than the set value and the pressure on the second pressure sensing unit 2 is lower than the set value (it is determined that the user does not lean against the backrest or only the infant sits on the second pressure sensing unit), the MCU does not execute the command of the control panel unit, and the sofa does not operate. So as to avoid the safety risk caused by the operation of the sofa by children; otherwise the seat is controlled by the control panel.
And 3, when the pressure on the first pressure sensing unit 1 and the second pressure sensing unit 2 is lower than the set value and lasts for a period of time (generally defined as several minutes to ten and several minutes), if the sofa posture is not the initial posture, the sofa automatically restores to the initial posture.
Example 2:
in the design of the cinema seat, a first pressure sensing unit 1 is arranged below a sofa cushion, a control panel is arranged at a sofa armrest, the control panel and the first pressure sensing unit 1 are connected with a control box, the control box comprises a signal processing unit and a motor driving unit, and the motor driving unit drives a motor execution unit (such as a linear push rod).
The control is realized by the programming of the MCU in the signal processing unit:
1, when no person sits on the seat, the pressure on the first pressure sensing unit 1 is lower than a set value, at the moment, the MCU does not execute the instruction of the control panel unit, and the seat is not controlled by the control panel unit; otherwise, the seat is controlled by the control panel.
2, when no person is seated on the seat, the pressure on the first pressure sensing unit 1 is lower than the set value, and after a certain period of time (generally defined as several minutes to ten and several minutes), if the seat posture is not the initial posture, the seat is automatically restored to the initial posture. So as to avoid influencing the passage of personnel and cleaning personnel.
It should be noted that:
in the above embodiments, the pressure sensing unit may be a pressure sensor, a seat membrane switch, or other switches capable of sensing pressure; the first pressure sensing unit 1 is laid to cover a proper range; the second pressure sensing unit 2 has to be laid at a reasonable height in order to be able to identify an adult.
