Detailed ways

In the following, only some exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive.

The treadmill transmission system of the present invention will be described below with reference to FIGS. 1 to 5 .

Referring to FIG. 1 , in one embodiment, the treadmill transmission system of the present invention includes a primary transmission wheel 1 , a secondary transmission wheel 2 , a metal disc 3 and a magnetic assembly 4 .

Wherein, the primary transmission wheel 1 rotates coaxially with the sprocket 5 of the treadmill. In this way, when the motor drives the crawler belt of the treadmill to move, the sprocket 5 will rotate accordingly, thereby driving the primary transmission wheel 1 to rotate.

As shown in FIG. 2 , a plurality of aluminum strips 71 are installed on the chain fixing belt 7 to form a track. After driving the motor, the crawler belt will move around the sprocket 5, thereby driving the rotation of the sprocket 5. In order to ensure that the two sprockets 5 at the front end of the treadmill can rotate stably, a front roller 61 can be set between the two, and the two sprockets 5 can be connected by the front roller 61 . Similarly, a rear roller 62 can also be arranged between the two sprockets 5 at the rear end, and the two sprockets 5 can be connected through the rear roller 62 .

Further, the secondary transmission wheel 2 is connected with the primary transmission wheel 1 through the first belt 11 , and the metal disc 3 is connected with the secondary transmission wheel 2 through the second belt 21 . Thus, while the primary transmission wheel 1 is rotating, it can drive the secondary transmission wheel 2 to rotate through the first belt 11 ; and the secondary transmission wheel 2 can further drive the metal disc 3 to rotate through the second belt 21 . In this way, a multi-stage transmission is formed between the primary transmission wheel 1, the secondary transmission wheel 2 and the metal disc 3, the transmission ratio is changed, and the rotating speed of the metal disc 3 is increased. On the contrary, when a small resistance is applied to the metal disc 3, a large resistance to the operation of the sprocket 5 can be generated.

In the present invention, the belt is a general term in the field, and it does not mean that it is made of leather, but is a general term for components that perform a transmission function.

Further, the magnetic component 4 can be rotatably connected to the frame (not shown in the figure) of the treadmill. Moreover, as shown in FIG. 3 , the magnetic component 4 can rotate close to the metal disk 3 during the rotation process. In this way, the magnetic component 4 will generate a magnetic field effect on the metal disk 3 , thereby hindering the rotation of the metal disk 3 .

When the rotating speed of the metal disc 3 decreases, it will affect the rotating speeds of the secondary transmission wheel 2 and the primary transmission wheel 1 in turn, so that the rotating speeds of the secondary transmission wheel 2 and the primary transmission wheel 1 are reduced. Furthermore, the primary transmission wheel 1 will affect the rotation speed of the sprocket 5 and reduce the rotation speed of the sprocket 5 . And when the rotating speed of the sprocket 5 decreases, it will directly generate resistance to the crawler belt moving thereon, thereby also increasing the movement resistance of the user in use.

Of course, as shown in FIG. 4 , the magnetic component 4 can also rotate away from the metal disk 3 . In this way, the magnetic field effect generated by the magnetic component 4 on the metal disk 3 will be reduced or eliminated, so that the metal disk 3, the secondary transmission wheel 2, the primary transmission wheel 1 and the sprocket 5 can still keep rotating at a relatively high speed. Furthermore, the movement resistance of the user in use is reduced.

Meanwhile, the magnetic force assembly 4 can also be connected with the handle (not shown in the figure) of the treadmill. In this way, the user can manipulate the handle according to his own needs at any time during use to make the magnetic component 4 rotate close to the metal disk 3, so as to increase the movement resistance and improve the movement intensity. You can also manipulate the handle according to your exercise fatigue to make the magnetic component 4 rotate away from the metal disc 3, so as to reduce exercise resistance and exercise intensity.

According to the transmission system of the present invention, the movement of the transmission mechanism can be hindered or indulged by applying a magnetic field force to the metal disc, thereby changing the resistance of the user during exercise and meeting the needs of the user for different exercise intensities. Moreover, the magnetic force provided by the magnetic force assembly 4 does not need to be very large, but through the multi-stage transmission of the secondary transmission wheel 2 and the primary transmission wheel 1, it can provide more than ten times the resistance to prevent the operation of the sprocket 5, thereby achieving the use or strengthen the effect of training.

Referring to FIG. 1 , in one embodiment, the primary transmission wheel 1 is coaxially connected with the sprocket 5 through a first rotating shaft 12 . The secondary transmission wheel 2 is provided with a second rotating shaft 22 , and the secondary transmission wheel 2 is rotationally connected with the frame body through the second rotating shaft 22 .

Further, one end of the first belt 11 is wound on the outer ring of the primary transmission wheel 1 , and the other end of the first belt 11 is wound on the outer ring of the second rotating shaft 22 . In this way, the primary transmission wheel 1 drives the second rotating shaft 22 to rotate through the first belt 11 , and then drives the secondary transmission shaft 2 to rotate. Because the diameter of the second rotating shaft 22 is small, the first belt 11 is directly wound on the second rotating shaft 22 , so that the rotation speed of the second rotating shaft 22 can be increased. Therefore, the rotational speed of the secondary transmission wheel 2 coaxial with the second rotating shaft 22 is further increased.

Referring to FIG. 2 , in one embodiment, the metal disk 3 is provided with a third rotating shaft 32 , and the metal sheet 3 is rotatably connected to the frame through the third rotating shaft 32 .

Further, one end of the second belt 21 is wound on the outer ring of the secondary transmission wheel 2 , and the other end of the second belt 21 is wound on the outer ring of the third rotating shaft 32 . In this way, the secondary transmission wheel 2 drives the third rotating shaft 32 to rotate through the second belt 21 , and then drives the metal disc 3 to rotate. Since the diameter of the third rotating shaft 32 is small, the second belt 21 is directly wound on the third rotating shaft 32 , so that the rotation speed of the third rotating shaft 32 can be increased. Thus, the rotational speed of the metal disc 3 coaxial with the third rotating shaft 32 is further increased.

According to the transmission system of the present invention, the first belt and the second belt are connected to the rotating shaft to transmit power to the secondary transmission wheel and the metal disc. Therefore, the rotational speed of the metal disc can be further increased under the condition that the input rotational speed of the sprocket is the same. On the contrary, when the magnetic component exerts resistance on the metal disk, the speed of the metal disk will decrease accordingly, and when it is transmitted to the sprocket and track through the secondary drive wheel and the primary drive wheel, a greater braking effect will be produced. At this time, the magnetic force provided by the magnetic assembly 4 does not need to be very large, but through the multi-stage transmission of the secondary drive wheel 2 and the primary drive wheel 1, it can provide more than ten times the resistance to stop the operation of the sprocket 5, thereby achieving The effect of user reinforcement training.

Referring to FIG. 1 and FIG. 2 , in one embodiment, a connecting seat 8 is provided on the frame body, and the magnetic component 4 is rotatably connected to the connecting seat 8 . By arranging an independent connection seat 8 to connect the magnetic component 4, it is possible to avoid the interference between the magnetic component 4 and other components on the frame when the magnetic component 4 is directly connected to the frame.

Referring to FIG. 5 , in one embodiment, the magnetic component 4 includes a first connecting arm 41 and a second connecting arm 42 . Wherein, the first connecting arm 41 and the second connecting arm 42 are arranged oppositely, and are pivotally connected with the connecting seat 8 . Therefore, the first connecting arm 41 and the second connecting arm 42 can rotate relative to the connecting base 8 to approach or move away from the metal disk 3 .

Further, a gap 10 is provided between the first connecting arm 41 and the second connecting arm 42 for the metal disk 3 to pass through. Moreover, the first connecting arm 41 is provided with a first magnetic component set 401 , and the second connecting arm 42 is provided with a second magnetic component set 402 .

The magnetic component group may include a whole magnetic component, or may include multiple independent magnetic components.

In this way, a magnetic field will be generated between the first magnetic component group 401 and the second magnetic component group 402, and when the magnetic component 4 rotates close to the metal disk 3, the metal disk 3 can move from between the first connecting arm 41 and the second connecting arm 42. The gap 10 in between passes through. Moreover, with the rotation of the metal disk 3 , it will cut the magnetic field lines in the magnetic field, and furthermore, the magnetic field will also generate resistance to the rotation of the metal disk 3 .

5, in one embodiment, the first magnetic component set 401 includes a first magnetic component 411 and a second magnetic component 412, and the second magnetic component set 402 includes a third magnetic component 421 and a fourth magnetic component piece 422. In this way, the arrangement of multiple magnetic components can enhance the magnetic field generated by the magnetic component 4 . Therefore, when the metal disk 3 (shown in conjunction with FIG. 1 ) passes through the gap 10 , stronger resistance can be given to the metal disk 3 .

Preferably, the first magnetic element 411 is disposed opposite to the third magnetic element 421 , and the second magnetic element 412 is disposed opposite to the fourth magnetic element 422 .

In this way, the magnetic fields generated by the first magnetic element 411 and the third magnetic element 421 can be superimposed on each other, and the magnetic fields generated by the second magnetic element 412 and the fourth magnetic element 422 can also be superimposed on each other, thereby enhancing the overall magnetic field strength. Therefore, when the metal disk 3 (shown in FIG. 1 ) passes through the gap 10 , the resistance of the magnetic field is relatively strong, which can increase the exercise intensity of the user to a greater extent.

1 and 5, in one embodiment, the first connecting arm 41 and the second connecting arm 42 are connected by a fixing plate 43, thereby ensuring that the first connecting arm 41 and the second connecting arm 42 Can rotate stably.

Further, a wire insertion portion 44 is disposed on the first connecting arm 41 . The wire insertion part 44 can fix a rope (not shown in the figure), and the rope is connected to the handle of the treadmill. In this way, the user can make the rope link the first connecting arm 41 by manipulating the handle, so as to drive the magnetic component 4 to rotate close to or away from the metal disk 3 .
