Abstract
The invention discloses a kind of video timely automatic-moving neck health protection chair, it is characterized in that: engine adopts reducing motor, output speed low torque is large, reliable; Transmission mechanism adopt Bevel Gear Transmission, be used for again deceleration force amplifier and change motor position configuration thus Appropriate application space; Executing agency adopts space crank mechanism, and the velocity variations of the driven member (i.e. connecting rod and column) of space crank mechanism is continuous print, can not produce shock and vibration; Column adopts angular contact ball bearing, thus greatly reduces the friction of column and base, bears to the reduction of executing agency.Revolving chair structure is arranged handrail and pedal, use safe and reliable.No matter it is that distance uses the neck deadlock occurred during video that this invention prevents and treats effectively, and can effectively anti-treating cervical spondylosis.And be difficult to discover because it runs naked eyes, do not hinder any operation, therefore can be used for computer at interior all videos.
Description
Technical field
The present invention relates to the life common electric articles for use of neck health care, specifically a kind of video timely automatic-moving neck health protection chair.
Background technology
Along with the progress of science and technology, people need the increasing time in the face of display screen, and the time making neck at a deadlock is more and more longer, this neck of originally degenerating for the mankind brings serious consequence, that is exactly the plumpness of posterior longitudinal ligament, the degeneration of vertebra and the instability of Minor articulus, add the motion lacking musculi colli, the atrophy of muscle, cause the instability that head is supported, the latter causes increasing the weight of of above-mentioned pathological condition more, due to the ligament that hyperplasia is thickening, the interverbebral disc pressuring nerve that spur is even given prominence to and blood vessel, the cervical spondylopathy of multiple symptom can be caused.The lighter is dizzy, nape portion is stiff and shoulder arm is numb, heavy then normal n and V, quadriplegia.This disease is formed under long-term bad fixing posture, so key is in control, and the reciprocating motion of head is exactly a kind of to the topmost motion exercise of cervical spondylopathy.In order to contain the stalemate of incidence before screen, someone just proposes with human eye is radius, allows screen make arc alternating translational, drives neck constantly to move back and forth by eye, certainly for the screen of close together, be a good selection owing to turning the large tool positive effect of degree for computer etc.; But for TV such remote due to turn degree very little, without any actual effect (eye microsaccade just counteracts relative motion); If really will work, amplitude probably at least half parlor of translation, obviously also unrealistic.Someone just proposes such scheme, and allow seat transfer TV and fix, the vertical range that such cervical vertebra is equivalent to for eye is very short, and rotational angle is quite large, and natural energy drives the reciprocating rotation of head, should say it is a preferably scheme.Notification number CN2779984Y, CN1695520A and 2834311Y utility model are exactly roughly the same like this scheme (each three embodiments of front two patents are substantially identical).But there are the following problems for these schemes: 1, used chair leg pulley without exception, can infer, there is larger frictional resistance on both feet and ground, a fixed wheel portion frictional force will be far smaller than the frictional force between transmission system as a result, frictional force between that produced by cushion and buttocks is also comparatively large, then both legs must swing with the rotation of swivel chair, due to the dynamic relation between pin and wheel, wheel is very sliding again, has to there will be the indefinite wheel of trend and walk about (or left or right or retrogressing etc.); Even if more likely your pin has lifted or loaded onto pedal, much smaller than turning round resistance between lower end drive mechanism and upper end drive mechanism, and there is laughable lower end drive mechanism and driven wheel turns in pulley itself and resistance over the ground, and the situation kept intact in upper end; 2, nearly all scheme is all that projection hang-up mode comes and goes, although filled easy spring vibration damper (actual this design also should spring add damping mechanism again), the mode of this impact type is certain to cause certain vibration for human body, and this is inappropriate for the people being in leisure or duty; 3, wherein have a scheme to have employed eccentric shaft to be combined with slotted disk mode, although this scheme overcomes the large shortcoming of impact in aforementioned schemes, realize mechanism and uninterruptedly to move more excellent mode, arrangement of mechanism does not meet convention.Designer using guide-bar mechanism as transmission mechanism using gear mechanism as executing agency, obviously unreasonable.Because motor output shaft is speed end in this mechanical system, torque is very little, and the ability of bearing moment variations is more weak.General machine driving arrangement is all slowed down through gear reduction unit by motor or directly use reducing motor, could drive executing agency after increasing torque; 4, all mention in second scheme in the first two patent with chain drive, Problems existing is that transmission arrangments is unreasonable.Rational Chain conveyer is not arranged in horizontal plane, all arranges in vertical plane.The chaindriven feature resistance that requires chain band should be loose, too tight greatly, in addition Chain conveyer can produce impact and noise.Fatal is if Chain conveyer is arranged in horizontal plane certainly want chain-taking.5, each scheme is in order to cater to the problem of lifting, all relate to one and have the gear being elevated just so segment length, but designer does not consider that the gear of length like this is unmanageable.
Summary of the invention
In view of prior art exists above-mentioned defect, technical problem to be solved by this invention uses reasonable, simple and reliable structure to realize the automatic left rotation and right rotation of neck health protection chair when watching video, making---system motion is steady, does not have shock and vibration, and on revolving chair structure, has added pedal.
Scheme advantage illustrates: (1) engine adopts reducing motor, and output speed low torque is large, reliable; (2) transmission mechanism adopt Bevel Gear Transmission, be used for again deceleration force amplifier and change motor position configuration thus Appropriate application space; (3) executing agency adopts space crank mechanism, and the velocity variations of the driven member (i.e. connecting rod and column) of space crank mechanism is continuous print, can not produce shock and vibration; (4) column adopts angular contact ball bearing, thus greatly reduces the friction of column and base, bears to the reduction of executing agency.(5) revolving chair structure is arranged handrail and pedal, use safe and reliable.(6) large owing to turning degree, and rotating speed is extremely slow, naked eyes do not see rotation, upper operation of might as well being in the way, therefore can be used for computer chair yet.
