Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

As mentioned above, the prior art treadmill has a certain functional defect more or less during the use, so the present invention provides a treadmill 200 with more optimized performance and a shock absorbing device 100 for the treadmill 200. Wherein, the treadmill 200 includes a running platform 210 and a base frame 220, the base frame 220 is located below the running platform 210, and a shock-absorbing device 100 is installed between the running platform 210 and the base frame 220. Through setting up this damping device 100, can play certain cushioning effect to running platform 210, when the sportsman runs on running the platform, the impact force when effectively absorbing the sportsman and running to effectively avoid the motion damage. Fig. 1 and 2 are schematic partial structural views of a treadmill 200 according to an embodiment of the present invention; fig. 3 shows a schematic structural diagram of a treadmill 210 according to an embodiment of the present invention; fig. 4 shows a schematic structural diagram of the bottom frame 220 according to an embodiment of the present invention.

As shown in fig. 1 and 2, the shock-absorbing device 100 includes a first magnetic member 110 mounted on a running board 210, and a second magnetic member 120 mounted on a base frame 220. Specifically, the first magnetic member 110 is fixed to the bottom surface of the front portion of the running platform 210, the second magnetic member 120 is fixed to the top surface of the running frame 220, and the second magnetic member 120 is disposed opposite to the first magnetic member 110 in the vertical direction with a certain interval. It should be noted that the end of the second magnetic member 120 opposite to the first magnetic member 110 has the same polarity, so that the magnetic repulsion force between the second magnetic member 120 and the first magnetic member 110 due to the same polarity can levitate and support the front portion of the running board 210. Here, the first magnetic member 110 and the second magnetic member 120 may be magnets having the same polarity at opposite ends, or may be other magnetic members.

Further, the damping device 100 further comprises two connecting rods 150, and two sides of the front portion of the treadmill 210 are movably connected with two sides of the base frame 220 through the connecting rods 150, respectively. In other words, the two connecting rods 150 are movably connected to the side of the front portion of the treadmill 210 and the side of the bottom frame 220, respectively. Wherein, the first end of the connecting rod 150 is movably connected with the running platform 210, and the second end of the connecting rod 150 is movably connected with the bottom frame 220.

According to one embodiment, as shown in fig. 2 to 5, the first and second ends of the connecting rod 150 are respectively provided with a connecting member 155. Both sides of the front of the running table 210 are respectively provided with a horizontal first rotating shaft 215. The horizontal second rotating shafts 225 are respectively provided at both sides of the bottom chassis 220. Here, the coupling portions 222 are respectively provided at both sides of the front portion of the bottom chassis 220, and the second rotation shaft 225 is fixedly provided at the coupling portions 222.

A first end of the link 150 is rotatably coupled to the first rotating shaft 215 through a coupling member 155, and a second end of the link 150 is rotatably coupled to the second rotating shaft 225 through a coupling member 155. Thus, the first and second ends of the connecting rod 150 are rotatably connected to the connecting portions 222 of the front side of the treadmill 210 and the side of the base frame 220, respectively. Alternatively, the connecting member 155 may be a copper sleeve or a bearing to realize a rotatable connection with the first and second rotating

shafts

215 and 225. However, the present invention is not limited thereto.

According to one embodiment, as shown in fig. 1 and 3, the rear portion of the running table 210 is further provided with a moving wheel 250, by which the rear portion of the running table 210 is rollably supported, so that when the front portion of the running table 210 is moved with respect to the base frame 220 by the link 150, the moving wheel 250 at the rear portion of the running table 210 can be engaged with the link 150 at the front portion of the running table 210, enabling the running table 210 to be flexibly moved with respect to the base frame 220.

When the athlete impacts the running platform 210 during running, the impact force is greater than the magnetic repulsive force between the first magnetic member 110 and the second magnetic member 120, and the front of the running platform 210 is pressed down. Specifically, as shown in fig. 6, the front portion of the treadmill 210 rotates around the first rotation axis 215 thereof, and the second end of the connecting rod 150 rotates around the second rotation axis 225 on the bottom frame 220, so that the included angle between the connecting rod 150 and the horizontal direction is reduced, and thus the front portion of the treadmill 210 approaches to the bottom frame 220, that is, the distance between the front portion of the treadmill 210 and the bottom frame 220 in the vertical direction is reduced. Accordingly, the distance between the first magnetic member 110 and the second magnetic member 120 is decreased, and the magnetic repulsive force is increased (i.e., the levitation supporting force for the treadmill 210 is increased). When the sporter is empty, the impact force on the running platform 210 is reduced, so that the front part of the running platform 210 can be lifted upwards to reset under the action of the magnetic repulsion force, that is, under the action of the magnetic repulsion force between the first magnetic member 110 and the second magnetic member 120, the front part of the running platform 210 reversely rotates around the first rotating shaft 215 thereof, and the second end of the connecting rod 150 is driven to reversely rotate around the second rotating shaft 225 on the bottom frame 220, so that the included angle between the connecting rod 150 and the horizontal direction is increased and reset.

It should be understood that when the athlete repeatedly strikes the treadmill 210 and empties while running, the increased magnetic repulsion between the first and second

magnetic members

110 and 120 overcomes a portion of the athlete's impact force when striking the treadmill 210, thereby providing some cushioning effect while the athlete is running, and the front portion of the treadmill 210 is lifted and repositioned by the magnetic repulsion when emptying. The above-mentioned cycle is repeated, so that the treadmill 210 can effectively absorb the impact of the exerciser, and has a good buffering effect, thereby avoiding exercise damage as much as possible.

Furthermore, it should be noted that the present invention does not limit the number of the first magnetic member 110 and the second magnetic member 120 in the damping device 100, and can be set one or more, as long as the second magnetic member 120 is disposed in cooperation with the corresponding first magnetic member 110, the above technical solution of the present invention can be implemented.

According to one embodiment, as shown in fig. 1 to 3, two first magnetic members 110 are provided, and the two first magnetic members 110 are spaced apart from each other at the bottom of the front portion of the treadmill 210. Accordingly, the second magnetic members 120 are provided in two, and the two second magnetic members 120 are spaced apart from each other on the top surface of the bottom frame 220 and are respectively disposed opposite to the two first magnetic members 110 in the vertical direction.
