Description

Intelligent chair and control method thereof

Technical Field

The invention relates to a chair, in particular to an intelligent chair and a control method thereof.

Background

In daily life, the chair is an indispensable office living article, and after people work and live conveniently, because a user carelessly leans too far back, the gravity center deflects, and people with the chair turn backwards, so that unnecessary dangers such as physical injury are caused.

Disclosure of Invention

The invention aims to solve the technical problem of providing an intelligent chair with high safety for coping with a backward overturn accident of the chair.

The invention is realized in such a way, and provides an intelligent chair which comprises a seat cushion, a chair back arranged at the rear side of the seat cushion, a chair frame for supporting the seat cushion and a locking part for locking/releasing the chair frame, wherein the chair frame comprises a plurality of chair legs, the chair legs are connected to a common central point, the central point is provided with a central hole for the chair frame to pass through, the bottom of the seat cushion is provided with a control unit, the control unit comprises a power supply, a processor and at least one first inductor which are electrically connected, the bottom of each chair leg is provided with at least one second inductor, and the processor is electrically connected with the second inductors and the locking part.

And provides a control method of the intelligent chair, which comprises the following steps:

the first sensor senses the weight change borne on the seat cushion and reports the weight change to the processor;

the processor sends a starting signal to the second sensor, and the second sensor senses the change of the pressure on the corresponding chair leg;

if at least one second sensor monitors that the pressure of the chair feet on the corresponding side is suddenly and greatly reduced, reporting to the processor; and

the processor instructs the lock to release the seat frame.

Compared with the prior art, above-mentioned intelligent chair relies on intelligent design, and the weight change on the monitoring seatpad starts the second sensor and measures whether unsettled of chair foot to instruct the locking part to release the chair frame, the chair frame descends fast under the action of gravity, the seatpad reduces rapidly, thereby makes the focus of user on the chair also descend fast thereupon, the focus is low then more steady, the user is even if fall down, also be difficult for be injured, so realized the unexpected remedy of chair back turn, the security has been improved.

Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 3, an intelligent chair according to an embodiment of the present invention includes a seat cushion 10, a seat back 20 installed at a rear side of the seat cushion 10, a seat frame 30 supporting the seat cushion 10, and a locking portion 40 locking/releasing the seat frame 30.

The chair frame 30 is a tubular structure, the bottom of the chair frame is provided with a plurality of chair legs 31, the plurality of chair legs 31 are connected to a common central point, the central point is provided with a central hole 32 for the chair frame to pass through, the bottom of the seat cushion 10 is provided with a control unit 50, the control unit 50 comprises a power supply 51, a processor 52 and at least one first inductor 53 which are electrically connected, the bottom of each chair leg 31 is provided with at least one second inductor 54, and the processor 52 is electrically connected with the second inductor 54 and the locking part 40.

The locking portion 40 is an electromagnetic device, and includes a first electromagnetic assembly 41 disposed in the chair frame 30 and a second electromagnetic assembly 42 disposed around the central hole 32 at the connection point of the chair leg, and both the first electromagnetic assembly 41 and the second electromagnetic assembly 42 are electrically connected to the control unit 50.

The first solenoid assembly 41 includes an annular first solenoid coil surrounding the center hole 32, and the second solenoid assembly 42 is an annular second solenoid coil disposed on an inner peripheral wall of the seat frame 30. The first and second electromagnetic coils are mutually attracted after being electrified, the magnetic force disappears after being powered off, and whether the first and second electromagnetic coils are electrified or powered off is controlled by the processor 52 of the control unit 50 according to monitoring signals of the first and second sensors 53 and 54.

The intelligent chair of this embodiment is that the operation should be turned over unexpected after the chair:

the first sensor 53 senses the weight change of the seat cushion 10 and reports the weight change to the processor 52, the processor 52 sends a starting signal to the second sensor 54, the second sensor 54 senses the pressure change of the corresponding seat leg 31, if at least one second sensor 54 detects that the pressure of the corresponding seat leg 31 is suddenly and greatly reduced, which indicates that the seat leg 31 is turned backwards, the processor 52 reports the pressure change to the processor 52, and the processor 52 instructs the locking part 40 to release the seat frame 30. Under the action of gravity, the chair frame 30 falls down, and the height H of the seat cushion 10 is simultaneously and rapidly reduced, so that the gravity center of a user on the intelligent chair also rapidly falls, the gravity center is relatively stable if the user falls down, the user is not easy to be injured, the accidental remedy of the backward overturn of the chair is realized, and the safety is improved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
