Description
The application is Application No.：201310130124.7, invention and created name is《Notebook computer lifting platform》, application
Day it is：The divisional application of the application for a patent for invention on April 15th, 2013.
Technical field
, can be by notebook when more particularly to one kind is used the present invention relates to a kind of use auxiliary equipment of notebook computer
Computer display screen is adjusted to the lifting platform for notebook computer of the appropriate location of Human Engineering Principle.
Background technology
Information age, computer and our study, work and live closely related.Notebook computer is compact, portable, it is deep by
Vast white collar, student, the favor of business people.But current situation is, notebook computer be placed in ordinary desktop in use,
Screen position is relatively relatively low, and people can only use computer with the incorrect sitting-pose for leaning forward, overlooking, and add neck pressure.The mankind
Ergonomics research shows, when cervical vertebra top rake is 15 °, continues to bend over the desk within 6 hours to have no that discomfort of neck area and electromyogram change, before cervical vertebra
Then discomfort of neck area showed increased when inclination angle is more than 30 °【1】.If the cervical vertebra of people exceedingly turns forward for a long time, just occur that neck aches
Bitterly, the symptom such as limitation of activity, or even the generation of cervical spondylopathy can be caused.
At present, solution to this problem is：Rationally to raise the height of display screen by using notebook computer desk,
The correct sitting posture for making people to come back, square one's shoulders uses notebook computer, reduces cervical vertebra forward leaning angle, so as to effectively mitigate cervical vertebra
Pressure, the generation of pre- preventing cervical spondylosis improves the quality of life of people.
Being presently available for adjusting the notebook computer desk of screen position substantially has 2 kinds：1st, fixed notebook computer desk,
