Cooperative damper for sports equipment and working method thereof

Abstract

The invention discloses a cooperative damper for sports equipment. The cooperative damper comprises a rack, a damping motor, a flywheel assembly, an electromagnet assembly and a controller. The flywheel assembly comprises a crankshaft and a metal piece; the electromagnet assembly is located on one side of the metal piece. The controller is used for controlling the magnitude of current passing through the damping motor and the electromagnet assembly. The invention further discloses a working method of the sports equipment collaborative damper. The working method comprises the following steps: S1, acquiring the pedaling frequency data of a user acting on the flywheel assembly and a torque value needed by the user; S2, comparing the obtained pedaling frequency data and the torque value required by the user with a pedaling frequency-torque threshold value, and controlling the generated resistance according to the comparison result; S3, continuously acquiring the pedaling frequency data in the next preset time and the torque value required by the user, and comparing the pedaling frequency data with the torque value required by the user to provide accurate resistance for the flywheel assembly. When the rotating speed is low, the defect that the damping motor generates resistance can be overcome through the electromagnet assembly, the resistance is mainly provided through the motor, and therefore, higher resistance precision is provided, and more electricity is saved.

Description

technical field [0001] The invention relates to the technical field of sports equipment, and relates to a cooperative damper for sports equipment and a working method thereof. Background technique [0002] When sports equipment (such as fitness machines and trainers) is working, it needs to provide force loads through dampers. Currently, commonly used dampers generally include mechanical damping, electromagnetic damping, and motor damping. [0003] For the mechanical damping type, it generally generates resistance through friction with moving parts. The resistance generated by this method is uncontrollable, and it is gradually eliminated in many high-end sports equipment. [0004] For the electromagnetic damping type, such as the electromagnetic resistance device disclosed in the patent document whose authorized announcement number is CN207843201U, it uses the principle of magnetic induction to place the rotating moving part in the magnetic field, and the moving part cuts th...

Problems solved by technology

[0004] For the electromagnetic damping type, such as the electromagnetic resistance device disclosed in the patent document whose authorized announcement number is CN207843201U, it uses the principle of magnetic induction to place the rotating moving part in the magnetic field, and the moving part cuts the magnetic field to generate eddy current, and the interaction between the eddy current and the magnetic field generates Ampere force , so as to generate resistance. Although this method greatly improves the precision of the generated resistance, the generation of eddy current is greatly affected by the material, so the resistance precision is not high enough, and because an external current is required to generate resistance, more power consumption

[0005] As for the motor damping type, such as the damping motor disclosed in the patent document whose publication number is CN109011332A, it provides load torque through the motor, so that the coil rotates and cuts the magnetic field line to generate current, and generates Ampere force, thereby generating resistance. The damper of this structure produces The precision of the resistance is sufficient and the power consumption is smaller, but when the speed of the coil is low, the resistance generated by the coil cutting the magnetic force line is also relatively small, so that the sports equipment cannot meet the ideal use effect at low speed.
