Abstract

The utility model provides an electric energy, kinetic energy, elastic potential energy are utilized to initial helping hand that can help the not enough crowd of arm strength to carry out the supplementary utensil that the chin was trained, the operator need provide according to wish preset and a helping hand is carried out in corresponding conversion, provides ascending pulling force to the user that power to the machinery of tempering the arm strength is accomplished in help.

Description

A kind of chin-up intelligence servomechanism

Technical field

A kind of auxiliary implement that the not enough crowd of arm strength can be helped to carry out chin-up training, operator presets the initial power-assisted that need provide by wish, the corresponding conversion of electric energy, kinetic energy, elastic potential energy and power is utilized to carry out power-assisted, there is provided pulling force upwards to user, thus complete the object of tempering arm strength.

Background technology

Now again along with the raising of people's living standard, children's rate of getting fat is more and more higher, generally unable to do what one wishes when doing chin-up, " national student physical health standard (revision in 2014) " (hereinafter referred to as new standard) that the Ministry of Education issues a few days ago, will come into effect; Relative to old edition standard, new standard eliminates selective-test item, arranges unified must survey project, and above boy student must survey chin-up in junior middle school, Ministry of Education body sanitation and art squad director Wang Dengfeng once announced one group of startling data, organized expert to test more than 20 ten thousand teenagers in China; Wherein in the chin-up test of the above boy student in junior middle school, there is people over half all to draw to get on, even have much both hands to hold thick stick and all hold incessantly.

Summary of the invention

Primary structure.

1: motor provides kinetic energy to mechanism.

2: gearbox makes the little moment of motor height rotating speed be transformed into slow-speed of revolution high-torque, so that extension spring.

3: ratchet and axle are synchronized with the movement, facilitate the braking of axle.

4: servos control ratchet.

5: ratchet carries out locked to ratchet and unlocks.

6: light sensor sends photosensor signal, make slow-speed shaft locked synchronous with motor braking maintenance.

7: slow-speed shaft scrolling belt stretches to spring.

8: spring store kinetic energy is elastic potential energy, provides power-assisted to user.

9: the initial tensile force that tensiometer display spring provides.

Operating principle.

1., by the control of motor rotation, gearbox deceleration, steering wheel, slow-speed shaft band movable reel scrolling belt, applying pulling force to spring increases its elastic potential energy.

2., when the pulling force of spring reaches pulling force needed for user, the stuck ratchet of servos control ratchet, the light sensor simultaneously on ratchet provides signal makes motor stall.

3. when cylinder is locked, spring provides pulling force to user, helps user to complete chin-up action.After exercise terminates, open steering wheel switch, unclamp ratchet and put down belt.

Accompanying drawing explanation

Fig. 1 is integrated model sketch.

Fig. 2 is assembling schematic diagram.

1: motor provides kinetic energy.

2: gearbox makes the little moment of motor height rotating speed be transformed into slow-speed of revolution high-torque.

3: ratchet and axle are synchronized with the movement, facilitate the braking of axle.

4: ratchet carries out locked to ratchet.

5: servos control ratchet.

6: light sensor makes slow-speed shaft locked synchronous with motor braking maintenance.

7: slow-speed shaft scrolling belt stretches to spring.

8: spring store kinetic energy, provides power-assisted to user.

9: the initial tensile force that tensiometer display spring provides.

Detailed description of the invention

Utilizing battery to power to motor 1 and steering wheel 5, motor and steering wheel work, just can provide power-assisted to taking exercise.

Motor output shaft reduces rotating speed by gearbox 2 and increases moment, two ratchet 3 gearbox slow-speed shaft 7 is equipped with, ratchet makes axle not limited rotational under the control of steering wheel, rolls belt, extension spring 8, tensiometer 9 is installed on spring top, when the tension force of spring reaches the state of user's needs, the locked ratchet of servos control ratchet 4, on ratchet, light sensor 6 sends signal, make motor stall, at this moment just can perform physical exercise.

When user takes exercise complete, open steering wheel switch and put down belt, spring is restored to the original state, use and terminate.

Claims (1)

1. a chin-up intelligence servomechanism, it is characterized in that: be a kind of auxiliary implement that the not enough crowd of arm strength can be helped to carry out chin-up training, utilize electric energy, kinetic energy, conversion between elastic potential energy and power, motor output torque is converted into person taking exercise's lumbar traction power, and is realized the adjustment of tractive force size by sensor and tensiometer, help the user of different demand to complete the object of chin-up exercise.
