Linear motor for imparting vibration to a supported body

Abstract

An electrically-powered linear motor for a whole body vibration (WBV) machin e is disclosed for producing and imparting vibrations to a platform for supporting a user. The linear motor comprises one or more pairs of generally aligned coil s for producing electromagnetic responses in one or more magnets, each disposed generally intermediate a pair of coils. Current is intermittently passed through the coils to produce vibrations within a desirable frequency range in the platform.

Description

technical field [0001] The invention relates to a whole-body vibration training machine for health care and training, in particular to a vibration training machine in which a linear motor is used to produce a vibration effect on a human body. Background technique [0002] At present, there is a method called vibration training, which mainly uses machinery to cause human muscle oscillations to achieve the effect of stimulating neuromuscular muscles. Its strength depends on the frequency and amplitude of vibrations generated by mechanical appliances. The resulting period, and the amplitude is half the difference between the maximum and minimum values ​​in the periodic vibration. The physiological mechanism of vibration training is mainly similar to the "stretching and shortening cycle" of enhanced training. It uses the mode of action of concentric contraction immediately after eccentric contraction, and through the influence of elasticity and stretching reflex, the muscles pro...

AI Technical Summary

Problems solved by technology

[0004] However, the vibration structure of the above-mentioned vibration training machine is mostly driven by the motor to form an eccentric vibration effect. Not only the mechanism components are more complicated, so the volume of the training machine increases, and it is difficult to transport and store.
