Along with the development of computer technology, computer becomes indispensable a kind of instrument in people's study, work, the life gradually, and its customer group expands to various ordinary persons from the professional workforce, comprises children and old man.Being widely used of computer brought enormous benefits and simultaneously easily to the mankind, and its harm to the user is also following, such as electromagnetic radiation to the harm of human body, screen to the injury of eyes, use computer to the injury of cervical vertebra etc. for a long time.
For with computer as (particularly being engaged in for a long time the personnel of the occupations such as editor, typewriting, secretarial, financial accounting, writing) for the personnel of the essential tool of routine work, owing to bending over one's desk working for a long time, make cervical vertebra be in for a long time flexing position or some special body position, not only make the increased pressure in the cervical intervertebral disk, and make musculi colli be in for a long time non-coordination stress, nape muscle and ligament are subject to the tractive strain, anterior margin of vertebral body is worn and torn mutually, hyperplasia, add reverse, lateroflexion is excessive, further cause damage, cervical spondylosis occurs.
The survey showed that for the authority of the 211st hospital of PLA: the time of the being engaged in incidence of disease of person's disease of cervical vetebra below 3 years is 14%; Person's incidence of disease was 26% in 4 ~ 7 years; Person's incidence of disease was 42% in 7 ~ 10 years.Through the x2 check, be engaged in the time length of computer operation, with the trouble cervical spondylosis substantial connection is arranged.The permanent single posture of bending over the desk can be accelerated cervical spine degeneration and damage process.
In recent years, annual newly-increased cervical spondylosis number just increased with the ratio of geometrical progression.
More seriously: the cranium of taking the lead on the cervical vertebra, lower connect trunk, be movable at most positions in the vertebra, also be the most important position of nerve center, the only way which must be passed of cardiovascular and cerebrovascular especially, in case break down, consequence is serious.
To this, brainstrust has proposed to prevent this sick measure and the method by the medical means treatment, but produces little effect.Reason is: which kind of method no matter all is difficult to change the reality of sitting quietly for a long time, keep changeless posture when people use computer for a long time.
Since computer comes out, in people's inertial thinking, long-term use computer easily is directed at cervical spondylosis always and is considered as the intrinsic characteristics of this instrument of computer, except changing user's oneself use habit, there is not solution.In fact, why use for a long time computer can cause cervical spondylosis, exactly because the computer monitor of tracing it to its cause is fixed all the time, computer monitor maintains static and has formed a kind of routine.This routine has limited people and has sought to solve the problem of using computer to cause cervical spondylosis from computer.Therefore, to so far, for using computer easily to cause this problem of cervical spondylosis, except reminding user is had a rest in good time, still do not set about carrying out solution from computer monitor.
Summary of the invention
The objective of the invention is to cause for the use that solves above-mentioned computer the problem of cervical spondylosis, propose a kind ofly can allow people when using computer, passively the solution of movable cervical vertebra.
For achieving the above object, the technical solution adopted in the present invention is: a kind of movable computer display device, comprise display unit main body and be used for the support substrate of support displays main body, it is characterized in that, also comprise the moving drive mechanism that automatic driving display main body moves with respect to support substrate.
Technique scheme has broken through in decades all routines of fixed placement computer monitor, like never before be portable with display design, come the driving display main body mobile reposefully by add moving drive mechanism for display device, with the moving and shake the head or the pitching head of display device, and then reach the passively effect of movable cervical vertebra with the guiding user.This technological scheme can fundamentally solve the problem of using computer easily to cause cervical spondylosis.On more wide in range meaning, the large obstacle in the human use computer process has been cleared away in this invention, may use computer to bring revolution to the mankind.
In technique scheme, described movement is preferably steady movement, and shake or vibration do not appear in the described display unit main body that steadily refers in moving process; Described movement can be continuous moving, also can be interrupted movement; Can be any screen position that can change with the movement of the movable cervical vertebra of guiding user, mobile such as laterally (up and down), vertically (about) mobile or simultaneously or successively comprise the oblique movement of horizontal and vertical movement or tortuous mobile; Its move mode can be to move back and forth or loopy moving.Its mobile type can be planar movement, also can be that curved surface moves.
Described moving drive mechanism can have all multiple implementations to the driving of display unit main body, preferably cooperate power plant to realize by driving mechanisms such as comparatively simple screw nut driving mechanism, pulley mechanism, rack and pinion drive mechanism, cam mechanism, slidercrank mechanisms, the preferred motor of power plant wherein, the more preferably following direct current generator of voltage rating 5V is so that use the USB power supply.As select eccentric mechanism can also realize that the driving display main body does circumference and move.In addition, also can select cylinder assembly to cooperate the compressed gas source realization to the driving of display unit main body.
When selecting screw nut driving mechanism driving display main body to move back and forth, screw mandrel can be assemblied on the support substrate, by the motor driving rotation, nut and display unit main body to be fixed, nut is assemblied on the screw mandrel by the tapped hole that cooperates with screw mandrel on it.
When the movement of display unit main body is designed to laterally or tilts when mobile, screw mandrel will laterally or be obliquely installed, and rotate with screw mandrel for the gravity by display unit main body self prevents display unit main body, nut can be arranged on the center of gravity top of display unit main body.The horizontal move left and right of display unit main body for example, screw mandrel is horizontally installed on the support substrate, and by the forward and reverse rotation of motor driving, nut is fixed on the display unit main body top edge.The weight of display unit main body acts directly on the screw mandrel, when screw mandrel rotates, display unit main body with nut in the upper left right translation of screw mandrel.
