BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to a method of suppressing vibration, and more specifically to a method of suppressing vibration of a mechanical device imposing upon at least one human hand holding the mechanical device utilizing the fixing pin, the upper metal washer, the upper suppressing washer, the lower suppressing washer, and the lower metal washer to form the vibration-suppressing unit, and employing the vibration-suppressing units to collocate with a fixing rack to fix the actuating part onto the massage body, the upper vibration-suppressing washer and the lower vibration-suppressing washer stacked together specifically designed to have the same elasticity modulus, the two adjacent upper vibration-suppressing washers having different elasticity modulus, the two spaced away but not adjacent upper vibration-suppressing washers having the same elasticity modulus, thereby implementing the effect of absorbing vibration strength because of the two adjacent upper vibration-suppressing washers with different elasticity modulus vibrating asynchronously, and suppressing and alleviating the vibration level to hand due to counterforce.

2. The Prior Arts

Generally, it is a common disease for people that muscles are easily fatigue, sore, or pain, especially for those who do not instantly exercise or keep a bad posture for a long time. Thus, many devices are developed to alleviate muscular fatigue, sore, or pain. One of the most popular and widely used is a massager.

The conventional massage vibrates by means of a massage head driven by an electric motor using vibration force. The user holds the massager and aligns the massage head to the target portion of human body for massage. Thus, counterforce generated by the massager is directly imposed upon the human hand holding the massager. Since the massager is usually heavy due to the built-in motor and battery pack, the human hand is possibly liable to fatigue after a long time of operation, or other portions of human body like fingers, wrists, and arms potentially suffers from chronic and physical hurt.

Therefore, it is greatly needed to provide a new method of suppressing vibration upon human hand employing the vibration-suppressing units with different vibration suppressing effect and installing the vibration-suppressing units at specific locations to mounting an actuating part onto a case for suppressing original vibration level and protecting hand, thereby overcoming the above problems in the prior arts.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a method of suppressing vibration upon human hand, comprising the steps S10, S20, S30 S40, S50, S60, S70, S80, and S90 sequentially performed for suppressing vibration of a mechanical device imposing upon at least one human hand holding the mechanical device.

Specifically, the step S10 is performed by preparing a massage body and a holding part. The massage body has a plurality of accommodating parts, and each accommodating part is provided with an accommodating hole. Further, the number of the accommodating parts is an even integer not less than four, and that is, at least four accommodating parts are prepared. In the step S20, a transfer bar, a rotation plate, a rotation axis, and a motor are prepared, and then the step S30 is performed by preparing a fixing rack having a ring part, a center hole, and a plurality of fixing wings. Further, the number of the fixing wings is an even integer not less than four, and that is, at least four fixing wings are prepared. The ring part surrounds the center hole, and the fixing wings are placed on the ring part and outwards extending away from the center hole. Each fixing wing is provided with a fixing hole.

In the step S40, a plurality of vibration-suppressing units are prepared, and each vibration-suppressing unit comprises a fixing pin, an upper metal washer, an upper suppressing washer, a lower suppressing washer, and a lower metal washer. Further, the fixing pin comprises a metal screw with a screw nut, and each of the upper metal washer, the upper suppressing washer, the lower suppressing washer, and the lower metal washer is provided with a center through hole.

Next, the step S50 is performed by assembling the transfer bar, the rotation plate, the rotation axis, and the motor to form an actuating part. Specifically, the transfer bar is eccentrically and rotatably connected to the rotation plate, the rotation plate is further connected to the rotation axis, and the rotation axis is further connected to the motor. In the step S60, the fixing rack is placed and installed by placing the fixing wings in the accommodating parts, and the fixing hole of the fixing wing aligns the accommodating hole of the accommodating part. The step S70 is then performed by employing the vibration-suppressing units and the fixing rack to fix the actuating part onto the massage body. Specifically, the fixing pin sequentially penetrates the center holes of the upper metal washer and the upper vibration-suppressing washer, the fixing hole of the fixing wing, and the center holes of the lower vibration-suppressing washer and the lower metal washer from top to bottom. Thus, the fixing pin is fixedly accommodated in the accommodation hole to fix the actuating part onto the massage body.

The step S80 is performed by electrically connecting the motor and a battery. Finally in the step S90, the massage body and the holding part are connected together to form a case, and the case, the actuating part, the battery, the fixing rack, the vibration-suppressing units are thus assembled to form a massage gun. In addition, the massage gun is intended for inserting into a massage head, and the actuating part contacts and drive massage head to generate the reciprocal massage motion.

Moreover, the upper vibration-suppressing washer and the lower vibration-suppressing washer have the same elasticity modulus, the upper vibration-suppressing washers of the two adjacent vibration-suppressing units have different elasticity modulus, and the upper vibration-suppressing washers of the two vibration-suppressing units not adjacent but spaced away have the same elasticity modulus. It is preferred that the two adjacent upper vibration-suppressing washers have a ratio of elasticity modulus between 1:0.2 and 1:0.9.

In addition, another object of the present invention is to provide a method of suppressing vibration upon human hand, also comprising the steps S10, S20, S30 S40, S50, S60, S70, S80, and S90 sequentially performed for suppressing vibration of a mechanical device imposing upon at least one human hand holding the mechanical device. However, the upper vibration-suppressing washer and the lower vibration-suppressing washer have different elasticity modulus, the upper vibration-suppressing washers of the two adjacent vibration-suppressing units have different elasticity modulus, and the upper vibration-suppressing washers of the two vibration-suppressing units not adjacent but spaced away have the same elasticity modulus. Further, the lower vibration-suppressing washers of the two adjacent vibration-suppressing units have different elasticity modulus, but the lower vibration-suppressing washers of the two vibration-suppressing units not adjacent but spaced away have the same elasticity modulus. It is preferred that the two adjacent upper vibration-suppressing washers have a ratio of elasticity modulus between 1:0.2 and 1:0.9, and the two adjacent lower vibration-suppressing washers have a ratio of elasticity modulus between 1:0.2 and 1:0.9.

Therefore, the present invention assembles the fixing pin, the upper metal pad, the upper suppressing pad, the lower suppressing pad, and the lower metal pad to form a vibration-suppressing unit, and employs the vibration-suppressing units in collocation with a fixing rack to fix the actuating part onto the massage body. In particular, the upper vibration-suppressing washer and the lower vibration-suppressing washer stacked together are specifically designed to have the same elasticity modulus, the two adjacent upper vibration-suppressing washers have different elasticity modulus, and the two spaced away but not adjacent upper vibration-suppressing washers have the same elasticity modulus. As a result, the two adjacent upper vibration-suppressing washers with different elasticity modulus vibrate asynchronously due to different vibration amplitude or frequency to interfere with each other so as to implement the effect of absorbing vibration strength like vibration amplitude and reduce the original rigid vibration, thereby suppressing and alleviating the vibration level to hand due to counterforce.
