Power regulating mechanism of cycle ergometer

Abstract

The invention discloses a power regulating mechanism of a cycle ergometer. The power regulating mechanism comprises a magnetic coil formed by embedding a plurality of permanent magnets on an arc-shaped steel plate, and a flywheel arranged on one side of the magnetic coil and having a certain gap with the magnetic coil, a force sensor used for conducting force is mounted on the magnetic coil, a base is arranged at the other end of the force sensor, and an embedded electric control device used for reading signals of a potentiometer and the force sensor, used for controlling the rotation speed ofa deceleration motor and used for receiving and processing pedal frequency signals of the cycle ergometer and heart rate signals is arranged in the base. With the power regulating mechanism of the cycle ergometer, on the basis that the real-time power output of the human body is measured, the output power during the cycling process of the human body can be dynamically regulated, so that the poweroutput is stabilized within a certain range. Compared with the traditional common friction type power regulating mechanism, the power regulating mechanism provided by the invention has the advantagesthat no equipment loss is caused, the regulating precision is high, a tested person can be subjected to testing and training under the constant-power mode, and the mechanism can be taken as the effective tool for evaluating the aerobic exercise ability of the tested person and realizing scientific bodybuilding.

Description

technical field [0001] The invention relates to the technical field of power vehicles, in particular to a power adjustment mechanism for power vehicles. Background technique [0002] The power bike is a commonly used sports fitness equipment. Compared with the traditional adjustable resistance spinning bike, it has the function of testing the output power of the human body. It can be used for sports test evaluation, rehabilitation training and other occasions. The power adjustment mechanism is the core component of the dynamometer of the power vehicle, which can generate and adjust the size of the exercise load during exercise. According to the different resistance adjustment methods, it can be divided into friction damping type, magnetic control type and self-generating type. Among them, the cost of the friction damping type is the cheapest, but the adjustment accuracy is low, and the friction parts are easy to wear and tear. The self-generating type has strong continuous...

Among them, the friction damping type is the cheapest, but the adjustment accuracy is low, and the friction parts are easy to wear and tear

The self-generating type has strong continuous adjustment ability, high adjustment accuracy, and flexible adjustment methods, and is adopted by many high-end power vehicles, but its structure is complicated and the cost is high.

The magnetic control type is widely used in the field of spinning bicycles, but few of them can measure the real-time power, and the power bicycles currently on the market generally do not have the function of intelligent constant power adjustment, so it is necessary for the testee to maintain a relatively constant power when pedaling. In the constant power range, this is difficult for general users, and will eventually affect the accuracy of test results
