Referring to fig. 1A to 5 of the specification, a resistance-adjustable rolling wheel 1000 according to a preferred embodiment of the present invention will be described in the following description, wherein the resistance-adjustable rolling wheel 100 includes a resistance adjustment device 100, a rolling wheel 200, and a metal spacer 300, wherein the resistance adjustment device 100 has a magnetic surface 101, and the rolling wheel 200 has a magnetic surface 201 and a receiving space 202. The rotator wheel 200 is held outside the resistance adjustment device 100 such that the magnetic surface 201 corresponds to the magnetic surface 101 of the resistance adjustment device 100, and the resistance adjustment device 100 is held in the receiving space 202 of the rotator wheel 200. The rotary wheel 200 is rotatably driven with respect to the resistance adjustment device 100. For example, but not limited to, the user may drive the rotator wheel 200 to rotate relative to the resistance adjustment device 100 by pedaling, hand shaking, etc., and the user performs exercise and fitness during driving the rotator wheel 200 to rotate relative to the resistance adjustment device 100. The metal spacer 300 is held between the magnetic surface 101 of the resistance adjustment device 100 and the magnetic surface 201 of the rotatable wheel 200. Further, the resistance adjustment device 100 is operably held at one side of the rotator wheel, and the resistance adjustment device 100 can change the amount of resistance applied to the rotator wheel 200 by changing the distance between the magnetic surface 101 and the magnetic surface 201 of the rotator wheel 200. In this manner, the user is allowed to select different resistance levels to achieve the appropriate exercise intensity.
Specifically, referring to fig. 3 to 5, the resistance adjustment apparatus 100 includes a first magnetic shoe 110, a second magnetic shoe 120, a rotating member 130, and a substrate 140, wherein the first magnetic shoe 110 and the second magnetic shoe 120 respectively have the magnetic force surface 101. The rotation member 130 is rotatably mounted on the base plate 140, and the first magnetic shoe 110 and the second magnetic shoe 120 are movably held at both sides of the rotation member 130.
The rotor 200 is made of a metal material, that is, the magnetic surface 101 of the rotor 200 is a metal surface, and the rotor 200 is rotatably held outside the first and second magnetic shoes 110 and 120 such that the magnetic surface 201 corresponds to the magnetic surface 101 of the first and second magnetic shoes 110 and 120. The metal spacer 300 is held between the magnetic surface 101 of the rotor 200 and the magnetic surface 101 of the resistance adjustment device 100 so as to be attached to the magnetic surface 101 of the rotor 200.

More specifically, referring to fig. 4B, the first and second magnetic shoes 110 and 120 are maintained at both sides of the rotation member 130 with a space therebetween, and when the first and second magnetic shoes 110 and 120 move close to each other, the magnetic force surfaces 101 of the first and second magnetic shoes 110 and 120 are close to each other, and at the same time, the magnetic force surfaces 101 of the first and second magnetic shoes 110 and 120 move in a direction away from the magnetic surface 201 of the rotary wheel 200. At this time, when the rotator 200 rotates with respect to the resistance adjustment device 100, the resistance applied to the rotator 200 decreases.
Referring to fig. 4A, when the first and second magnetic shoes 110 and 120 are distant from each other, the magnetic force surfaces 101 and 101 of the first and second magnetic shoes 110 and 120 are distant from each other, and at the same time, the magnetic force surfaces 101 and 101 of the first and second magnetic shoes 110 and 120 are moved toward a direction close to the magnetic surface 201 of the rotary wheel 200. At this time, when the rotator 200 rotates with respect to the resistance adjustment device 100, the resistance applied to the rotator 200 increases.
In this embodiment of the present invention, the resistance adjustment device 100 further includes a first linking member 150 and a second linking member 160, wherein two ends of the first linking member 150 are rotatably connected to the upper portion of the rotating member 130 and the upper portion of the first magnetic shoe 110, respectively, and two ends of the second linking member 160 are rotatably connected to the lower portion of the rotating member 130 and the lower portion of the second magnetic shoe 110, respectively. The lower portion of the first magnetic shoe 110 is rotatably mounted to the lower portion of the base plate 140, and the upper portion of the second magnetic shoe 120 is rotatably mounted to the upper portion of the base plate 140. In the process that the rotating member 130 rotates relative to the substrate 140, the rotating member 130 drives the first linking member 150 and the second linking member 160 to move, and the first linking member 150 and the second linking member 160 respectively drive the first magnetic shoe 110 and the second magnetic shoe 120 to move, so that the first magnetic shoe 110 and the second magnetic shoe 120 approach to each other or move away from each other.
For example, when the rotating member 130 is driven to rotate clockwise relative to the base plate 140, the rotating member 130 drives the first linking member 150 to move from left to right, and simultaneously, the rotating member 130 drives the second linking member 160 to move from right to left. The first linkage member 150 pulls the first magnetic shoe 110, the lower portion of the first magnetic shoe 110 rotates clockwise relative to the base plate 140, the upper portion of the first magnetic shoe 110 is close to the upper portions of the rotating member 130 and the second magnetic shoe 120, and the magnetic surface 101 of the first magnetic shoe 110 moves in a direction away from the magnetic surface 201 of the rotating wheel 200. The second linkage 160 pulls the second magnetic shoe 120, the upper portion of the second magnetic shoe 120 rotates clockwise relative to the base plate 140, the second magnetic shoe 120 is close to the lower portions of the rotating member 130 and the first magnetic shoe 110, and the magnetic surface 101 of the second magnetic shoe 120 moves in a direction away from the magnetic surface 201 of the rotating wheel 200. In this process, the distance between the magnetic surface 101 of the resistance adjustment device 100 and the magnetic surface 201 of the rotator 200 is gradually increased, and the resistance applied to the rotator 200 is gradually decreased when the rotator 200 is driven to rotate.
Further, when the rotating member 130 is driven to rotate counterclockwise relative to the substrate 140, the rotating member 130 drives the first linking member 150 to move from right to left, and simultaneously, the rotating member 130 drives the second linking member 160 to move from left to right. The first linkage member 150 pushes the first magnetic shoe 110, the lower portion of the first magnetic shoe 110 rotates counterclockwise relative to the substrate, the upper portion of the first magnetic shoe 110 is far away from the rotating member 130 and the upper portion of the second magnetic shoe 120, and the magnetic surface 101 of the first magnetic shoe 110 moves toward the direction close to the magnetic surface 201 of the rotating wheel 200. The second linkage 160 pushes the second magnetic shoe 120, the upper portion of the second magnetic shoe 120 rotates counterclockwise relative to the substrate 140, the second magnetic shoe 120 is far away from the rotating member 130 and the lower portion of the first magnetic shoe 110, and the magnetic surface 101 of the second magnetic shoe 120 moves toward the direction close to the magnetic surface 201 of the rotating wheel 200. In this process, the distance between the magnetic surface 101 of the resistance adjustment device 100 and the magnetic surface 201 of the rotator wheel 200 is gradually decreased, and the resistance applied to the rotator wheel 200 is gradually increased when the rotator wheel 200 is driven to rotate relative to the resistance adjustment device 100.
That is, the resistance adjustment device 100 of the present invention can easily drive the first magnetic shoe 110 and the second magnetic shoe 120 to approach or separate from each other by using the rotating member 130, the first connecting member 150, and the second connecting member 160, and has a simple structure and a compact assembly. Not only the overall structure of the resistance adjusting device 100 is simplified, but also the resistance adjusting device 100 is smoother in the actual adjusting process, the failure rate and the power consumption of the resistance adjusting device 100 are greatly reduced, and meanwhile, better use experience is brought to a user.
It is worth mentioning that the first magnetic shoe 110 and the second magnetic shoe 120 are driven to approach each other and move away from each other by driving the rotating member 130 of the resistance adjusting device 100 to rotate clockwise and counterclockwise, so that the moving range of the first magnetic shoe 110 and the second magnetic shoe 120 can be increased. In this way, the allowable adjustment range of the resistance received by the rotary wheel 200 in the process of rotating relative to the resistance adjustment device 100 is larger, and the resistances with different levels can be obviously distinguished, thereby being beneficial to meeting the requirements of users on different exercise strengths and further improving the use experience of the users.
