Description

Rhythm Health Machine

The invention is a rhythmic health machine, especially a rhythmic motivation that provides vertical reciprocating motion.

The motive is a kind of fitness equipment, which can provide vertical reciprocating movement. Users can perform exercises like skipping rope while standing on the motive.

Conventional motives mostly use a belt pulley combined with a connecting rod. For example, the reciprocating vibration exercise device of the Republic of China Patent Publication No. I660762, the vibration fitness machine No. I664004, and the vibration fitness training device No. I302469 are all belt pulleys combined with a connecting rod. Design, but the elasticity of the belt will cause relative sliding between the belt and the pulley (also called elastic sliding). Elastic sliding will cause power loss and poor transmission efficiency, and make the belt easy to aging and slack.

Furthermore, the conventional motive may shake slightly from side to side. As shown in the first figure, when the conventional motive is driven by the connecting rod 10 to move the cover 20 up and down, the fulcrum of the connecting rod 10 is fixed at On the base 30, therefore, the connecting rod 10 will link the cover body 20 in a slightly arc-shaped manner, so that the cover body 20 exhibits a rotational motion instead of a linear motion, so that the cover body 20 does not perform vertical linear reciprocating motion up and down completely. There may be shaking from side to side.

This side-to-side shaking situation can easily cause the user to dizzy slightly, but under long-term use, it can also have a negative impact on the body, such as a burden on the knee joints, especially the elderly or people with knee joint problems or knees. People with joint injuries. In view of this, how to Eliminating the above-mentioned deficiencies is the technical difficulty that the inventor of the case intends to solve.

In view of the above situation, the present invention provides a rhythmic health machine, especially a rhythmic motivation for the cover body to move up and down in the vertical direction without shaking from side to side.

In order to achieve the above objective, the present invention provides a rhythmic health machine, which includes a base, a cover, a driving mechanism, a first link group and a second link group. The base is provided with at least one guide rail, the at least one guide rail is perpendicular to the base; the cover is provided above the base, the cover is provided with at least one guiding portion, and the at least one guiding portion is inserted into the at least one The guide rail allows the cover to move vertically along the at least one guide rail; the driving mechanism is arranged in the base; the first connecting rod group is arranged in the base, the first connecting rod group It includes a plurality of links, the plurality of links includes a first link, a second link, a third link, a fourth link, a sixth link, and a seventh link. A connecting rod and the fourth connecting rod are connected to the driving mechanism, the second connecting rod and the sixth connecting rod are connected to the cover, the third connecting rod and the seventh connecting rod are connected to the base; and the second connecting rod The connecting rod group is arranged in the base, the second connecting rod group includes a plurality of connecting rods, and the plural connecting rods include an eighth connecting rod, a ninth connecting rod, a tenth connecting rod, and an eleventh connecting rod. Connecting rod, a thirteenth connecting rod and a fourteenth connecting rod, the eighth connecting rod and the eleventh connecting rod are connected to the driving mechanism, the ninth connecting rod and the thirteenth connecting rod are connected to the cover body , The tenth link and the fourteenth link are connected to the base.

Preferably, the at least one guide rail is provided with a linear guide groove.

Preferably, at least one guiding portion of the cover is provided with a guiding bearing or a sliding block.

Preferably, the driving mechanism is a double output shaft motor, and the double output shaft motor is provided with a A first eccentric shaft and a second eccentric shaft.

Preferably, the first link group further includes a fifth link, the fourth link is pivotally connected to the fifth link, and the fifth link and the sixth link are pivotally connected.

Preferably, the second link group further includes a twelve link, the eleventh link is pivotally connected to the twelfth link, and the twelfth link and the thirteenth link are pivotally connected.

Preferably, the plural connecting rods of the first connecting rod group and the second connecting rod group are pivotally connected to each other through a pivot bearing.

Thereby, the first eccentric shaft of the driving mechanism drives the first linkage group, and the second eccentric shaft drives the second linkage group, so that the first linkage group and the second linkage group are linked to the cover The body reciprocates up and down. Since the guide portion of the cover is inserted into the at least one guide rail, the guide bearing slides in the linear guide groove, so the cover can always be guided by the at least one guide rail. Keep the vertical up and down linear movement, there will be no shaking left and right.
