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 notebook computer lowering or hoisting gear 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,

See Fig. 4, power supply module 6 include power module 61, rise crawl button switch 62, decline crawl button switch 63,
Fan swicth 64, power supply indicator 65 and power outlet interface 66.Power module 61 is erected on the bottom plate 11 of base 1, and position
In the right rear portion of bottom plate 11.Rise crawl button switch 62, decline crawl button switch 63, fan swicth 64, power supply indicator
65 and power outlet interface 66 be fixedly installed on successively base 1 right plate 12-2 rising inching button jack, decline crawl
In button jack, fan swicth jack, power supply instruction lamp insertion hole and outlet jack.Rise crawl button switch 62, decline
Inching button switch 63, fan swicth 64, power supply indicator 65, power outlet interface 66 are electrically connected with power module 61.On
Rise inching button switch 62 and decline crawl button switch 63 and use tape light, it is small that normally opened, normally-closed contact shares a common port
The point driving switch of type button.Stroke protection component 5 front travel protection switch 51 and rear stroke protection switch 52 with power supply group
The power module 61 of part 6 is electrically connected.
Cooling fan 8 has 2, is arranged on the relevant position of the heat dissipation region both sides of supporting platen 7 by fastener respectively,
And on the bottom surface of supporting platen 7.2 cooling fans 8 are electrically connected with the power module 61 of power supply module 6.
See Fig. 4, Fig. 8, Fig. 9 and Figure 10, the notebook computer lowering or hoisting gear of the present embodiment is powered using direct current DC24V, electricity
Gas control principle uses bridge circuit, and wherein A1 is that to rise crawl button switch 62, A2 be to decline crawl button switch 63;K1 is
Front travel protection switch 51, K2 are rear stroke protection switch 52;M1 is the motor 21 of actuating unit 2;H is power supply indicator 65;
K3 is fan swicth 64, and M2 is cooling fan 8.The course of work of circuit is as follows:DC24V power supplys are connected, power supply indicator 65 becomes
It is bright.Fan swicth 64 is pressed, cooling fan 8 works.Press rising crawl button switch 62 or decline crawl button switch 63, pen
Remember that the supporting platen 7 of this computer elevating device realizes lifting action.When pressing rising crawl button switch 62, motor 21 is just
Turn, motor 21 drives screw mandrel 31 to rotate, and under the drive of ball nut 33, push rod 34 is rearward moved, and push rod 34 passes through left circle
Axis pin of column 41-10 and right cylindrical pin drive the connecting rod 41-9 of left connecting rod mechanism 41 and the connecting rod of right connecting rod mechanism 42 to be moved back by
It is dynamic, so as to drive the long connecting rod component 41-6 and short connecting rod component 41-4 of left connecting rod mechanism 41 and the long company of right connecting rod mechanism 42
Bar component and short connecting rod component are rotated with respective pivot forward upward, thus drive the rear portion of supporting platen 7 forward on
Fang Yundong, supporting platen 7 anterior forward downward motion, supporting platen 7 realize vertical motion, rising point are unclamped when rising in place
Dynamic button switch 62, motor 21 is stalled, and lifting platform keeps posture after the adjustment(Figure 10), then as being placed with pen in supporting platen 7
Remember this computer 9, while the display screen rise of notebook computer 9, display screen there will be larger leading X, and keyboard has rationally
Angle of inclination φ and relatively low forward position height Z.Exceed upper limit such as in uphill process, rear stroke protection switch 52 is rolled right
Its operating head is disconnected under sliding block 39-2 promotion, and normally closed rear stroke protection switch 52 is disconnected, and motor 21 is stalled, and is forbidden in continuation
Rise, rear stroke protection switch 52 serves lifting position-limit protective effect.Now, decline crawl button switch 63 is only pressed, is made
Motor 21 is inverted, and motor 21 drives supporting platen 7 to decline, and rear stroke protection switch 52 can just disconnected, circuit is exited rising
Position limitation protection.The decline control of the notebook computer lowering or hoisting gear of the present embodiment is similar to rising control process, need to only press down
Inching button switch 63, wherein 51 descending spacing protective effects of front travel protection switch drop.
See Fig. 9, rise crawl button switch 62 and decline crawl button switch 63 as pressed simultaneously in operation, then A1, A2
Contact is all closed upwards, and circuit can not form path, motor 21(M1)Stalling, serves protective effect.
See Figure 10, after the notebook computer lowering or hoisting gear of the present embodiment, the display screen center of notebook computer 9
Height Y can at most raise 200mm, and display screen maximum reach is 55mm apart from X, and the maximum tilt angle φ of keyboard is
15 °, the nearly body end height Z of keyboard is less than or equal to 50mm.
Obviously, above-described embodiment is only intended to clearly illustrate example of the present invention, and is not to the present invention
The restriction of embodiment.For those of ordinary skill in the field, it can also be made on the basis of the above description
Its various forms of changes or variation.There is no necessity and possibility to exhaust all the enbodiments.And these belong to this hair
Among the obvious changes or variations that bright spirit is extended out is still in protection scope of the present invention.
