Abstract

The embodiments of the invention provide a smart seat and a control method for the same, which smart seat includes a seat body, a vital sign detector and a controller. The seat body includes a backrest, a seating surface and a backrest driver for driving the backrest to make an open and close movement relative to the seating surface. The vital sign detector is used for detecting a vital sign of a user to obtain vital sign data. The controller is electrically connected with the backrest driver and the vital sign detector, respectively, determines that the user is in the sleeping state or the waking state according to the vital sign data of the vital sign detector, and controls the backrest driver to drive the open and close movement of the backrest relative to the seating surface according to the state of the user.

Claims

1. A smart seat, characterized in that, it includes a seat body, a vital sign detector and a controller,

the seat body includes a backrest, a seating surface and a backrest driver for driving the backrest to make an open and close movement relative to the seating surface,

the vital sign detector is used for detecting a vital sign of a user to obtain vital sign data, and

the controller is electrically connected with the backrest driver and the vital sign detector, respectively, determines that the user is in the sleeping state or the waking state according to the vital sign data of the vital sign detector, and controls the backrest driver to drive the open and close movement of the backrest relative to the seating surface according to the state of the user,

wherein the vital sign detector is an ultrasonic detector and a processing module, the ultrasonic detector is arranged on the front side of the seat body and sends an ultrasonic signal toward the direction of the seat body and receives a reflected ultrasonic signal, the processing module determines the user'"'"'s respiratory frequency and/or degree of chest undulation according to the information of the ultrasonic signal received by the ultrasonic detector, and the controller determines that the user is in the sleeping state or the waking state according to the user'"'"'s respiratory frequency and/or degree of chest undulation,

wherein on the ultrasonic detector is further arranged an alignment camera which is electrically connected with the controller, on the seat body is further arranged an alignment mark, and the alignment camera is used for capturing an image of the alignment mark, in order that the controller regulates the orientation direction in which the ultrasonic detector sends the ultrasonic signal according to the image of the alignment mark.

2. The smart seat as claimed in claim 1, characterized in that, the backrest is hinged with the seating surface by a side, and the backrest driver drives the backrest to make the open and close movement relative to the seating surface with its hinging side as the axis.

3. The smart seat as claimed in claim 1, characterized in that, the controller controls the backrest to change to the open state in a case in which the controller determines that the user is in the sleeping state according to the vital sign data.

4. The smart seat as claimed in claim 3, characterized in that, it further includes a pressure sensor which is arranged on the seating surface and electrically connected with the controller, and the controller is used for controlling the backrest to be in the close state in a case in which the pressure value born on the seating surface detected by the pressure sensor is less than a preset threshold.

5. The smart seat as claimed in claim 2, characterized in that, the vital sign detector is an ultrasonic detector and a processing module, the ultrasonic detector is arranged on the front side of the seat body and sends an ultrasonic signal toward the direction of the seat body and receives it, the processing module determines the user'"'"'s respiratory frequency and/or degree of chest undulation according to the information of the ultrasonic signal received by the ultrasonic detector, and the controller determines that the user is in the sleeping state or the waking state according to the user'"'"'s respiratory frequency and/or degree of chest undulation.

6. The smart seat as claimed in claim 3, characterized in that, the vital sign detector is an ultrasonic detector and a processing module, the ultrasonic detector is arranged on the front side of the seat body and sends an ultrasonic signal toward the direction of the seat body and receives it, the processing module determines the user'"'"'s respiratory frequency and/or degree of chest undulation according to the information of the ultrasonic signal received by the ultrasonic detector, and the controller determines that the user is in the sleeping state or the waking state according to the user'"'"'s respiratory frequency and/or degree of chest undulation.

7. The smart seat as claimed in claim 1, characterized in that, the seat body further includes a leg supporting plate hinged with the seating surface by a side of the leg supporting plate and a leg supporting plate driver arranged between the seating surface and the leg supporting plate, and the leg supporting plate driver is electrically connected with the controller and used for driving the leg supporting plate to make an open and close movement relative to the seating surface with its hinging side as the axis under the control of the controller.

8. The smart seat as claimed in claim 2, characterized in that, the seat body further includes a leg supporting plate hinged with the seating surface by a side of the leg supporting plate and a leg supporting plate driver arranged between the seating surface and the leg supporting plate, and the leg supporting plate driver is electrically connected with the controller and used for driving the leg supporting plate to make an open and close movement relative to the seating surface with its hinging side as the axis under the control of the controller.

9. The smart seat as claimed in claim 3, characterized in that, the seat body further includes a leg supporting plate hinged with the seating surface by a side of the leg supporting plate and a leg supporting plate driver arranged between the seating surface and the leg supporting plate, and the leg supporting plate driver is electrically connected with the controller and used for driving the leg supporting plate to make an open and close movement relative to the seating surface with its hinging side as the axis under the control of the controller.

10. The smart seat as claimed in claim 1, characterized in that, on the back of the backrest is further arranged a supporting piece which is retracted on the back of the backrest and parallel to the back and can be opened to support the backrest when the smart seat changes to be in the open state.

11. The smart seat as claimed in claim 1, characterized in that, it further includes at least one vibration sensor, the vibration sensor is arranged on the seating surface and electrically connected with the controller, and the controller is used for driving the vital sign detector to detect a vital sign of the user in a case in which the vibration state value on the seating surface which is detected by the vibration sensor in a preset period of time is less than a preset threshold.

12. The smart seat as claimed in claim 1, characterized in that, on the seat body is further arranged a control button which is electrically connected with the controller and used for controlling the backrest driver to drive the open and close movement of the backrest relative to the seating surface after the control button is triggered.
