A power adjustment mechanism for a power car

Abstract

The invention discloses a power adjustment mechanism of a power car, which comprises a magnetic coil embedded in an arc-shaped steel plate by a plurality of permanent magnets, and a flywheel arranged on one side of the magnetic coil and maintaining a certain gap with it. A force sensor for conducting force, the other end of the force sensor is provided with a base, and the base is provided with signals for reading potentiometers and force sensors, for controlling the speed of the deceleration motor, and for receiving and processing the cadence of the power vehicle Embedded electronics for signal and heart rate signals. The power adjustment mechanism of this kind of power car can dynamically adjust the output power during the riding process of the human body on the basis of measuring the real-time power output of the human body, so that the power output can be stabilized within a certain range. Compared with the mechanism, there is no equipment loss and high adjustment accuracy. It can be used as an effective tool for evaluating the tester's aerobic exercise ability and scientific fitness for the tester to test and exercise in the constant power mode.

Description

Technical field [0001] The present invention relates to the field of power cars, and is specifically a power vehicle power conditioning mechanism. Background technique [0002] Power car is a commonly used sports fitness equipment, which increases the function of testing the human output power than the traditional adjustable resistance of the traffic, which can be used in sports test assessment, rehabilitation training. The power conditioning mechanism is the core component of the power car measurement, which can generate and regulate the motion load size during the movement. Different from the resistance adjustment method, it can be divided into friction damping, magnetron, and self-generating. Among them, the frictional damping is the most cost, but the accuracy is low, and the friction component is easy to lose. The self-generating continuous adjustment is strong, the adjustment is high, the adjustment is flexible, and many high-end power cars are used, but their construction ...

AI Technical Summary

Problems solved by technology

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
