Abstract

An intelligent anti-sleeping chair, wherein a control center is composed of a singlechip and a battery and installed on the bottom frame of a chair support frame; the battery, a first DC motor and a second DC motor are respectively connected with the singlechip by a lead; and a sensor is connected with the singlechip by a signal wire. A plastic cap is sleeved at the end of a vertical support rod; a fixing pin is arranged at the place where the vertical support rod is close the end so as to limit the displacement of the plastic cap; the plastic cap can move freely up and down in the through hole of the chair bearing surface; the chair bearing surface is fixedly connected with the chair support frame by a fastening bolt; and a guide rod is fixed on the bottom frame of the chair support frame by a rod fixing sleeve. The intelligent anti-sleeping chair has the following advantages: when having lessons, the sensor sends the signal to the control center by the signal wire; if the height of the shoulders collected by the sensor is lower than the scope set beforehand, the control center supplies power to the first DC motor; finally, the up and down movement of the plastic cap is realized so as to remind the students of not sleeping.

Description

The anti-couch of intelligence

Technical field

The utility model relates to the anti-couch of a kind of classroom intelligence, particularly monitor automatically in a kind of classroom, automatically controls, and improves the anti-couch of intelligence of classroom efficiency, belongs to field of Education and teaching.

Technical background

Along with the economy of China, the high speed development of technology, education becomes China and realizes that country revives, name family rich and powerful assurance, and the Party Central Committee, State Council and governments at all levels all attach great importance to the development of education and formulate various preferential policies to guarantee the universal and development of educational undertaking for the development of educational undertaking for this reason.But because Students ' Learning subject is many, learning pressure is large, can not guarantee the sufficient length of one's sleep, the students' union of good large quantity lies prone and dozes off on desk on classroom, and quality of instruction is declined, and this phenomenon has affected the development of Chinese education cause to a certain extent.Seek a kind of method prevents that student from dozing off and seems extremely important for this reason.

Summary of the invention

The purpose of this utility model is, solves above-mentioned existing existing problem, the anti-couch of intelligence that provides a kind of student of preventing to doze off.

The utility model is achieved in that single-chip microcomputer, battery connect and compose control centre and be arranged on the underframe of chair bracing frame, battery, the first dc motor, the second dc motor are connected by wire with single-chip microcomputer respectively, and sensor is connected by holding wire with single-chip microcomputer.

Motor cabinet is arranged on the underframe of chair bracing frame, the first dc motor is arranged on motor cabinet, the output shaft of the first dc motor is installed cam, cam is by the first axle, the 3rd circlip is connected with connecting rod, small end and lateral frame bar are by the second axle, the first circlip connects, lateral frame bar and longitudinal support bar are bolted, the second back-up ring is fixed on longitudinal support bar, the lower end of spring is fixed on the second circlip, spring housing is contained on longitudinal support bar, the upper end of spring is fixed on thermoplastic plastic cap, thermoplastic plastic cap sleeve is contained in the end of longitudinal support bar, longitudinal support bar is provided with steady pin near end position, can limit the displacement of thermoplastic plastic cap, thermoplastic plastic cap can freely move up and down in chair loading end through hole, chair loading end and chair bracing frame are connected by trip bolt, guide post is fixed on the underframe of chair bracing frame by solid bar cover,

The second dc motor is arranged on by support on the rear back side of chair bracing frame, the second DC motor output shaft connects leading screw by shaft coupling, screw is installed on leading screw, screw outside is connected by screw loading plate, sensor is installed on loading plate, the support casing of loading plate is contained on feed rod, and linear bearing is installed on feed rod, and linear bearing is fixed on the rear back side of chair bracing frame.The end mounting limit plate of leading screw.

The utility model has the advantages that lower class hour: by advance control centre being set, in the time not starting and quit work, thermoplastic plastic cap upper end is concordant with chair upper surface.

Upper class hour: by inputting start-up time and the motor main story reversing time identical with the class period to control centre in advance, after starting, control centre gives the second dc motor power supply, sensor starts to move up and down to gather the signal of student's both shoulders height, sensor is passed to control centre signal by holding wire, and control centre is by determining whether starting the first dc motor to the processing of signal.If the both shoulders At The Height that sensor gathers is in the scope of setting in advance, control centre does not start the first dc motor;

If the both shoulders height that sensor gathers is lower than the scope of setting in advance, control centre gives the first dc motor power supply, finally realize thermoplastic plastic cap move up and down remind student not sleep.

Thereby improve the quality of teaching, progressively promote the development of Chinese education cause, make it have the features such as safe, accurate, comfortable.
