The object of the invention is to design provides a kind of drawback problem that can solve existing equipment and exist, meet that work teaching and everyday home use simple and reasonable, reliability is higher, can prolonged application in the multifunctional all blank of different use occasion.
The present invention designs and produces and to be achieved through the following technical solutions.
Main body of the present invention, primarily of compositions such as aluminum alloy frame and collateral fagging, flexible blank, base plate, blackboard eraser, driving shaft, tensioning shaft, scanning device, scanning device support, small projector and support, shooting support, spacing meter and corresponding mechanical transmission mechanism, wedge mechanism, screw-nut body, control circuit and direct current permanent magnet motors.Motor is connected with leading screw by yielding coupling; Roll-type blackboard eraser is connected with driven gear by axle; Flexible blank is wound multi-plane structure (analog band transmission) by multiaxis, and its driving shaft is connected with driving gear and motor; Base plate is fixed by locating hole; Roll-type blackboard eraser is connected to realize moving up and down by wedge and slide block with screw-nut body.
Scan function is realized by radio scan equipment & installation support, and support is bolted and is connected with the upper back of general frame, and scanning device contacts with flexible blank, manual control selective scanning when blank rotates.
Projecting function is realized by micro-projection device and projection bracket and can more conveniently selective dismounting.Classroom can be used to have projecting apparatus in work teaching use procedure, flexible blank serves as curtain and uses, and this device can be selected in using by family.
Above-described Multifunction blank, framework and axle, train, corresponding mechanism and motor etc. are checked to choose and are determined according to following relational expression:
1, according to power required during transmission, design voltage 12V, power is 30W, revolution 60r/min.
2, gearratio: i1/i2=1:3
3, the strength and stiffness of axle are checked
Optical axis:
Multidiameter:
In formula: T---the moment of torsion suffered by axle, N.mm;
The coefficient of rigidity of the material of G---axle, MPa, for steel
The polar moment of inertia of Ip---shaft section, for circular shaft
L---multidiameter is by the length mm of torsional interaction;
Ti, li, Ipi---represent multidiameter i-th section upper suffered moment of torsion, length and polar moment of inertia respectively;
Z---multidiameter is by the shaft part number of torsional interaction;
4, Q235A elected as by the material of axle, and 20. table look-up knows that [tT] is at 15 ~ 20MPa.
This described equipment, circuit control system mainly comprises positive and negative rotation circuit, limit sensors, governor circuit, direct current permanent magnet motor, control button.
Multifunctional all illusion blank of the present invention, simple and reasonable, can be applicable to different operating occasion, cost performance is high, convenience and high-efficiency, environment-friendly multi-purpose.
Accompanying drawing explanation
Accompanying drawing 1 is multifunctional all blank outside framework structural representation of the present invention.
Accompanying drawing 2 is the outer inside subject structural representation of multifunctional all blank of the present invention.

In figure: 1 is aluminum alloy frame and collateral fagging, 2 are shooting supports, 3 are projection brackets, 4 be scanning device and support, 5 are chutes, 6 are leading screws, 7 are wedge mechanisms, 8 are roll-type blackboard erasers, 9 are driving shafts, 10 are tensioning shafts, 11 are driving gears, 12 are driven gears, 13 are slide blocks, 14 is flexible blanks.
Detailed description of the invention
Below in conjunction with accompanying drawing of the present invention, to the technical scheme in the invention process process carry out clear, intactly describe, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection scope of the present invention.
Multifunctional all illusion blank of the present invention, its detailed description of the invention is.
When using beginning, blank (14) is in static tensioned state and by backplanes support, user can write thereon.
In writing process, when person to be used needs turn-over temporarily to retain, can press switch activated motor 1 rotate forward to one end, driven by motor transmission mechanism makes blank rotate turn-over; Before need looking back during content, user can press the switch other end, and starter motor M reverses, by content recovery.
As needs store written contents, user can start scanning apparatus and carries out scanning storage (4) and form electronic edition by being wirelessly transmitted to computer when turn-over, or can also carry out video recording preservation to whole process while of being taken pictures preserved by the capture apparatus (3) of front end.
Scouring process, press controller upper switch, starter motor M drives screw-nut body (5,6,13) and wedge mechanism (7) that blackboard eraser (8) is moved upward and to contact with blank, and controlling its lifting position by spacing meter, now main driven gear (11,12) engagement makes roll-type blackboard eraser coordinate with blank to clean; At the end of scouring, press controller lower switch, make wedge mechanism (7) drive blackboard eraser to move downward, set back and put, clean complete.
When needs project, blank is turned to non-written portion as projection screen by user's starter motor, now, manually can delineate as required, encloses painting etc. on blank, avoids the electronic softwares such as PPT and writes and delineate not accurate drawback.
