Description
Technical Field
The utility model relates to a learning tools technical field, concretely relates to seat of adjustable lumbar support back cushion.
Background
Most people have incorrect posture correction, are inclined and bent when sitting, seem to move conveniently, and bring much hidden danger to people; the long-term poor sitting posture can cause the fatigue of neck muscles, cause neck and shoulder pain, neck muscle spasm and even cause dizziness; over time, cervical disc degeneration will occur prematurely after adulthood, leading to cervical spondylosis. The correct sitting posture requires the waist to exert force continuously, and the waist is often aching and painful after sitting for a long time.
The traditional seat is of a fixed mechanical structure, and the angle of a seat back cannot be adjusted; in order to protect the waist, a back cushion is arranged at the center of the chair back, but the method is very little for correcting sitting postures, because the sitting position of a person is changed frequently, and the thickness and the position of the back cushion are fixed.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose: in view of the technical problems still existing in the background technology, the chair capable of adjusting the lumbar support back cushion is designed, the front and back positions of the back cushion can be adjusted through the rocker, the position of the back cushion can be changed according to the sitting position of a person at any time, a certain auxiliary effect can be provided for the sitting posture correction, and the waist is protected.
The technical scheme adopted for solving the problems is as follows:
a chair capable of adjusting a lumbar support headrest comprises a chair body, a headrest, support rods on the hands of the chair body, a two-way rocker switch, a push rod motor and a control system.
The back cushion is arranged on the backrest part of the chair body and is controlled by a push rod motor to push forwards or backwards, the two-way rocker switch is fixedly connected at the front end of the supporting rod,
the control system adopts a 51 single chip microcomputer as a controller, the front and back stretching positions of the back cushion are adjusted through a bidirectional rocker switch and a push rod motor,
the bidirectional rocker switch is provided with four wiring ports, two ports of the four wiring ports are connected with 5V of the 51 single-chip microcomputer, the other two ports are connected with IO ports of the 51 single-chip microcomputer to serve as input detection signals, when the cross rocker switch is pushed forwards or backwards, level signals on the IO ports of the 51 single-chip microcomputer can be turned over, and when the level signals on the IO ports of the 51 single-chip microcomputer are turned over, signal judgment is carried out; when the signal is a forward signal, the control system controls the push rod motor to extend forward by adopting a 51 single chip microcomputer; when the signal is a backward signal, the control system 51 controls the push rod motor to retract backward through the single chip microcomputer.
The utility model has the advantages that:
this seat of adjustable lumbar support back cushion can adjust the front and back position of back cushion through the rocker, can be at any time according to the position change back cushion's that the people sat the position, can correct the appearance of sitting and provide certain additional action, protection waist.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1-6, the present embodiment provides a seat with an adjustable lumbar support headrest, which includes a seat body 2, a headrest 4, a support rod 3 at a hand of the seat body 2, a two-way rocker switch 1, a push rod motor 5, and a control system.
Specifically, the back cushion 4 is arranged on the backrest part of the chair body 2 and is pushed forwards or backwards under the control of a push rod motor 5, and the bidirectional rocker switch 1 is fixedly connected to the front end of the support rod 3.
The control system adopts a 51 single chip microcomputer as a controller, and the front and back telescopic positions of the back cushion 4 are adjusted through the bidirectional rocker switch 1 and the push rod motor 5.
The bidirectional rocker switch 1 is provided with four wiring ports, two ports of the four wiring ports are connected with 5V of the 51 single-chip microcomputer, the other two ports are connected with IO ports of the 51 single-chip microcomputer to serve as input detection signals, when the cross rocker switch is pushed forwards or backwards, level signals on the IO ports of the 51 single-chip microcomputer can be turned over, and when the level signals on the IO ports of the 51 single-chip microcomputer are turned over, signal judgment is carried out; when the signal is a forward signal, the control system adopts a 51 single chip microcomputer to control the push rod motor 5 to extend forwards, and when the signal is a backward signal, the control system 51 single chip microcomputer controls the push rod motor 5 to retract backwards.
When the rocker switch is pushed downwards, the push rod motor 5 drives the back cushion 4 to extend forwards; when the rocker switch pushes upwards, the push rod motor 5 drives the back cushion 4 to retract backwards; when the rocker switch is pushed forwards, the back cushion 4 on the push rod motor 5 extends forwards; when the rocker switch is pushed backwards, the back cushion 4 on the push rod motor 5 is retracted backwards.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes, modifications, substitutions and alterations can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art, and the scope of the present invention is defined by the appended claims and their equivalents.
