Intelligent electromagnetic fitness equipment damper

Abstract

The invention provides an intelligent electromagnetic fitness equipment damper for replacing the conventional balance weight iron. Because a magnetic powder clutch has the characteristic that the size of the transmission torque has proportional linear relation with the magnetizing current but is not related to the slip frequency speed thereof, the size of the moving resistance is changed by a method of controlling the size of the slip frequency torque generated by the magnetizing current by controlling the magnetizing current. An accelerating mechanism consisting of a planetary gear train increases the rotating speed to reduce the allowable torque transmission value of the used magnetic powder clutch. Input and output ends of the magnetic powder clutch are respectively connected with two gears generating rotating speed difference in a differential mechanism consisting of two gear pairs with different speed ratios to acquire lower slip frequency speed to reduce the slip frequency powder. The intelligent electromagnetic fitness equipment damper changes the linear motion of the balance weight source of the conventional fitness equipment into the rotating motion, carries out real-timedetection on the fitness equipment by adopting a computer control system and carries out dynamic management on different requirements on different equipment through program setting.

Description

1. Technical field [0001] The invention is an intelligent electromagnetic type body-building equipment damper, which belongs to the technical field of body-building equipment. 2. Background technology [0002] Strength fitness equipment is mainly composed of two parts: the operating mechanism and the counterweight mechanism. The operating mechanism has its own special structure according to the position of the muscles to be trained, and the counterweight mechanism is basically the same in the series of products. At present, domestic The counterweight source of traditional strength fitness equipment at home and abroad all adopts the method of superimposed counterweight iron, which trains muscles by overcoming gravity, and its strength is adjusted by changing the number of counterweight iron. The method has the following disadvantages: [0003] ① The counterweight iron can only do vertical reciprocating motion, which occupies a large vertical space, so the counterweight sourc...

AI Technical Summary

Problems solved by technology

[0003] ① The counterweight iron can only do vertical reciprocating motion, which occupies a large vertical space, so the counterweight source can only be placed in a specific position as an independent unit, making the equipment occupy a large area;

[0004] ② Different training items have different lengths of motion trajectories. If the counterweight source is unified, it can only be designed according to the maximum stroke. For equipment with small strokes, redundant empty strokes will be generated, resulting in waste of materials;

[0005] ③The size of the force does not have the function of stepless continuous adjustment and dynamic change;

[0006] ④ Due to the purely mechanical structure, it is difficult to realize intelligent control;

[0007] ⑤ When the counterweight iron falls back, there will be impact and great noise, especially when the lifting wire rope or the connecting piece is broken, the counterweight iron will fall out of control and smash the equipment, and even accidents will occur
