Description
Technical field
The present invention relates to a kind of use auxiliary equipment of notebook computer, particularly a kind of notebook computer lifting platform that note-book computer display screen can be adjusted to the appropriate location meeting Human Engineering Principle when using.
Background technology
Information age, computer and our study, work and life closely related.Notebook computer is small and exquisite, portable, the dark favor by vast white collar, student, business people.But current situation is, when notebook computer is placed on and ordinary desktop uses, screen position is relatively on the low side, and people can only use computer with the incorrect sitting-pose leaning forward, overlook, and add neck pressure.Ergonomics research shows, when cervical vertebra top rake is 15 °, continues within 6 hours, to bend over the desk to have no discomfort of neck area and electromyogram changes, then discomfort of neck area showed increased when cervical vertebra top rake is more than 30 °
[1].If the cervical vertebra of people exceedingly turns forward for a long time, just there will be the symptom such as cervical pain, limitation of activity, even can cause the generation of cervical spondylopathy.
At present, solution to this problem is: by the height using notebook computer desk rationally to raise display screen, people are made to use notebook computer with the correct sitting posture coming back, square one's shoulders, reduce cervical vertebra forward leaning angle, thus effectively alleviate cervical vertebra pressure, the generation of pre-preventing cervical spondylosis, improves the quality of life of people.
Can be used at present regulating the notebook computer desk of screen position roughly to have 2 kinds: 1, fixed notebook computer desk, this side is that the computer desk structure of fixed triangle shape is simple, the position raising note-book computer display screen can be played, but height and position is unadjustable, display screen does not have leading to adjust, and cannot meet normal viewing distance requirement (sitting posture of come back, squaring one's shoulders can widen the distance of eyes and computer display screen).2, hinge type notebook computer desk (front hinged), this computer desk can regulate the height and position of display screen, but be subject to adopting front end hinged structure restriction, supporting platen can only around fixed-axis rotation, display screen only has very little leading adjustment, can not meet normal visible sensation distance and regulate requirement, when panel flip angle is larger, keyboard slant angle is excessive, and wrist operation is very awkward.If Chinese patent literature CN20098748OY (application number is 2006200079298), Chinese patent literature CN201200105Y(application number are 2008201079913) all disclose a kind of computer table for pocketbook, namely there is problem as above.
(1. Zhu Qi star. college student bends over the desk to learn the mechanical analysis of neck loading logical. Chinese school health, 1997 (3))
