Abstract
The invention discloses an automatically adjustable back cushion which is fixed on a fixing device of a chair. The back cushion is characterized in that the cushion comprises a worm gear (1), a sliding adjustment part (2), a lead screw (3), a worm (4), a motor driving device for driving the worm to rotate, and a shell part (5) to which all the mechanisms above are attached, wherein the motor driving device is connected with a control circuit and provided with an infrared sensor device; the infrared sensor device controls the connection or disconnection of the control circuit according to the contact condition between the human body and the sliding adjustment part (2) of the back cushion, and provide the stopping or the starting of a control motor which provides power to a worm gear/worm device so as to control the rotation and the reversion thereof; when the worm gear (1) and the worm (4) move, the worm gear (1) drives the lead screw (3) connected therewith to rotate; and through the rotation of the lead screw (3), the sliding adjustment part (2) connected and attached to the lead screw (3) slides in a straight line. The automatically adjustable back cushion is suitable for the common chairs for family use and office use, and has a wide application scope.
Description
Technical field
The present invention relates to a kind of electronic health device, particularly relate to a kind of can self-regulating back cushion.
Background technology
Most people have a lot of times throughout one's life and on chair, spend, and according to the difference of occupation, the probability that is sitting in study office on the chair for a long time increases, and at this moment incorrect posture very easily causes the tired even damage of lumbar vertebrae.
Though many people oneself can heightened awareness arrive the importance that keeps correct body position, in the process of study, work, can keep correct posture on one's own initiative at the beginning; But perhaps can not note the posture of oneself for a long time owing to utilize the computer office; How long often crossed not, just changed correct posture, as too leaning forward gradually, bending over; Thereby make lumbar vertebrae crooked for a long time, cause the tired even damage of lumbar vertebrae.
If can come the sitting posture of automatic mediator's body through equipment, be to improve one of selection of solution preferably that above-mentioned present situation institute can adopt, can be used to correct user's sitting posture.
Summary of the invention
In view of the existing problem that exists, but the present invention proposes a kind of automatic and adjustable joint back cushion, be used to the instrument of assisting people to correct faulty sitting posture, in use regulate the height of back cushion automatically, make vertebra be in vertical state, and then alleviate the burden of lumbar vertebrae.
A kind of self-adjustable back cushion; Back cushion is fixed on the fixture of chair; It is characterized in that; This back cushion comprises part 2, leading screw 3, worm screw 4, drive worm screw motor rotating drive unit that turbine 1, slidingtype are regulated and the housing parts 5 that above mechanism depended on, and wherein: the assembling motor driver connects control circuit, and is provided with the infrared sensing apparatus; The infrared sensing apparatus contacts with the part 2 of the slideable adjusting of back cushion or does not contact according to human body; Realize that control circuit breaks off or connection; Stopping or starting of control motor is provided, and control motor is that turbine, endless screw apparatus provide power to control it and rotate and to commutate; When turbine 1 moved with worm screw 4, turbine 1 drove connected leading screw 3 rotations; Through the rotation of leading screw 3, make that being connected the outer part 2 that is attached to the slidingtype adjusting on the leading screw 3 does linear slide.
The part 2 that said slidingtype is regulated is carried out return control; Promptly when the people leaves; Receive signal by infrared sensing device; Obtain the people and leave that automatic control circuit makes the motor counter-rotating drive worm screw 4, turbine 1 then behind the signal, thereby system reverse rotates part 2 returns that make the leading screw counter-rotating make slideable adjusting.
The part 2 that 5 pairs of slidingtypes of said housing parts are regulated realizes coating spacing.
Compared with prior art, the present invention is applicable to common family, handles official business and use seat, and the scope of application is extensive; Can regulate the protruding amplitude of back cushion so that adapt to the various bodily forms and personal habits better according to people's different demands; When the people leaves for a long time, make the back cushion return by the automatic control of infrared sensing device, avoided because of forgetting the situation that causes long-time unlatching of turning off.
Description of drawings
Fig. 1 is the device generalized section of self-adjustable back cushion of the present invention;
Fig. 2 is the enforcement illustration of self-adjustable back cushion of the present invention.
The specific embodiment
The present invention helps the posture that people correct lumbar vertebrae through the height of regulating back cushion; Realize by following scheme; Referring to Fig. 1, this back cushion comprise turbine 1, slideable adjusting part 2, leading screw 3, worm screw 4, drive worm screw motor rotating drive unit and housing parts 5 that above mechanism depended on, be used for back cushion is fixed on the fixture 6 of chair.The assembling motor driver connects control circuit, and installs the infrared sensing apparatus additional.The situation that the infrared sensing apparatus contacts with cushion based on human body; The starting or stop of control motor; In case when human body did not touch the part 2 of slideable adjusting, control circuit was connected, the control motor is that turbine, endless screw apparatus provide power to rotate and commutation to control it; When turbine 1 moved with worm screw 4, turbine 1 drove connected leading screw 3 rotations again; Through the rotation of leading screw, make that being connected the outer part 2 that is attached to the slideable adjusting on the leading screw does linear slide; In like manner, in case when human body touched the part 2 of slideable adjusting, control circuit broke off, slip stops, thereby realizes the adjustment of sitting posture.Fixture 6 fibrous material for having retractility helps and being connected of shell 5.
When the people leaves, the infrared sensing device perception is arranged, thereby automatic control circuit makes the motor counter-rotating drive worm screw 4 then, turbine 1 system reverse rotates part 2 returns that make the leading screw counter-rotating make slideable adjusting.
Because the coating position-limiting action of 5 pairs of slippers 2 of housing parts, so slipper 2 no longer needs the spacing separately action that can be implemented in linear slide on the leading screw as the moving component on the leading screw 3 in the practical implementation process.
Implement for example with reference to Fig. 2; At first this back cushion is fixed in the correct position of seat with fixture 6, after the people sits down, actuating motor; Driving worm screw rotates; Then turbine operation, leading screw rotates the rectilinear motion of realizing slipper, thereby reaches the target that laterally moves of the part 2 of the protruding slideable adjusting of back cushion.During use,, realize the adjustment of sitting posture based on the suitable height of personal habits setting back cushion.
