Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
1 table leg frame, 2 stepper motor expansion links, 3 telescopic piston, 4 swash plate connecting rods, 5 folding gears, 6 folding connecting rods, 7 wobble gears, 8 folding lower side links, 9 folding upper side links, 10 swing connecting bar, 11 infrared ray sensors, 12 flashing lamps, 13 desktops, 14 buzzers, 15 inclination angle detection sensors, 16 ultrasonic sensors, 17 folding buttons, 18 ultrasound distance sensors, 19 bearings, 20 supports, 21 oscillating motors, 22 wobble cranks, 23 folding cranks, 24 folding motors, 25 swash plates, 26 stepper motor drivers, 27 power supplys, 28 single-chip microcomputers.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further described.
Referring to such as Fig. 1, this detailed description of the invention by the following technical solutions: the present invention is according to modern intelligent design requirement, and " multifunctional intellectual desk " is divided into four major parts, is namely control section, importation, output, slave part.Namely importation is import outer surface information into by sensor, such as find student sleep, measure student height, judge that whether sitting posture of student correct.Control section is that input outside signal is carried out integrated treatment, is equivalent to the brain of people, is then fixed programming to single-chip microcomputer 28, can realize the effect pre-established.Whether output is the executing agency that programmed instruction sends, and is the mechanical mechanism for realizing design effect in advance, be unusual pith, be related to desk function and realize.Slave part be make desk design more rationally, more various, more intelligent.The present invention is directed to and avoid student to attend class doze, detected by ultrasonic sensor 16 and infrared ray sensor 11 and find that student lies prone at desk in bed, sensor information feeds back to rapidly single-chip microcomputer 28 by sensor assembly, single-chip microcomputer 28 judges, whether ultrasonic sensor 16 mainly detects desktop has object, and infrared ray sensor 11 mainly detects whether barrier is people, human body temperature the chances are 37 °, two sensors feedback signal simultaneously, strengthens the correctness of detection.Then by programming to single-chip microcomputer 28, programming content finds that signal is after five minutes, and executive signal sends, and delivers to stepper motor driver 26 and oscillating motor 21, realizes controlling the upper and lower slight oscillatory of desktop by oscillating motor 21 work.Desktop is swung and is realized by Planar Crank-and-rocker Mechanism, it is made up of wobble crank 22 and swing connecting bar 10, desktop is actually the side link in mechanism, present design pendulum angle is 12 degree, that suitable plane swings up and down 6 degree, in order to desktop swings steadily, the crank and rocker mechanism crank angle between two limit positions during design swings is 0 degree, without acute return characteristic.The present invention can realize the height automatically adjusting desk, when student sits down, now student's height measured by ultrasound distance sensor 18, altitude signal is fed back to single-chip microcomputer 28, then programming is carried out according to daily life seat optimum height table or personal habits, again by stepper motor driver 26 and stepper motor expansion link 2, desk carries out automatic lifting to meeting student's height, makes student's efficiency of listening to the teacher improve like this.The present invention can realize Anti-myopic eye, in desktop front end, inclination angle detection sensor 15 is housed, when inclination angle detection sensor 15 normally will be read a book according to student, from this position to the angle initialization of people, when sitting posture of student not just, sensor detects, angle signal is imported into single-chip microcomputer 28, single-chip microcomputer 28 is by programming, and output signal, acts on flashing lamp 12 and buzzer 14, flashing lamp 12 worked before this, if also do not correct incorrect sitting-pose, buzzer 14 gives the alarm sound, reaches reminding effect like this.The present invention's desk auto-changing that can also realize attending class becomes conference table or student experimenting table.Folding switch button 7 is housed before desktop.When we need to become conference table, as long as press shift knob, single-chip microcomputer 28 acknowledge(ment) signal, by simple programming, controls speed and the time of folding motor 24.Fold mechanism is made up of two planar linkage mechanisms, is namely from stepper motor out, is first crank and rocker mechanism, then arrives double rocker mechanism.Crank and rocker mechanism realizes circular motion to oscillating motion.Swash plate has two effects, and during as desk, be keep off in side, playing fixing desk effect, when becoming conference table, is become desktop from swash plate.Swash plate two location comparisons are special, and during as desk, needs are vertical, and as conference table, needing is level.Connecting rod in double rocker mechanism is connected with swash plate by swash plate connecting rod, and be parallel to each other, the angle that connecting rod was put is 90 degree.Folding motor 24 passes to folding lower side link 8 by folding crank 23 motion, and folding lower side link 8 swings, and realizes the swing of swash plate 90 degree.When being folded into conference table, folding upper side link 9 is parallel with frame linking, and desk support forms right angled triangle with folding lower side link, plays balance and stability effect.The present invention has a transverse slat on support, puts thing use to student.This desk design size and modern teaching teaching aid meet, attractive in appearance and innovate.
The utility model beneficial effect is: structure is attractive in appearance, and weight is little, collapsible, takes up space little, intelligent, multi-functional in one, student can be helped to prevent and treat myopia, prevent student's classroom sleeping, automatic Debugging goes out desk height when student sits down.
The above, only in order to the technical solution of the utility model to be described and unrestricted, other amendment that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in right of the present utility model.
