[0002] As people's living standards continue to improve, fitness equipment such as elliptical machines, walking machines, or exercise bikes are becoming increasingly popular. In some elliptical machine devices, in order to monitor some of the user's physical parameters or apply a weak current to the acupuncture points on the user's soles to relieve the user's fatigue, electrodes need to be set on the pedals of the elliptical machine, and these electrodes need to be connected to the electronic control system on the host. Under the control of the electronic control system, the electrical signals from the user's soles are collected or a microcurrent is applied to the user's soles. In existing elliptical machine devices, the electrical connection between the pedals and the host is often achieved by leaking wires. When in use, the wires are easily entangled on the rotating shaft of the pedals, and the wires may rub against other structures as the pedals move.

DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below. Figure 1 、 Figure 2 and Figure 5 The present invention provides an electrical conduction structure comprising a first sliding conductive structure and a second sliding conductive structure. The first sliding conductive structure is disposed between the pedal and its rotating shaft 100 and is electrically connected to the electrodes on the pedal. The second sliding conductive structure is disposed between the crank 700 and the output shaft of the resistance motor 600 and is electrically connected to the first sliding conductive structure via an intermediate conductive structure disposed on the crank 700.

[0025] In this embodiment, the first sliding conductive structure includes a conductive ring 200 and a first probe 110, and the second sliding conductive structure includes a conductive disc 400 and a second probe 500. The conductive ring 200, the first probe 110, the conductive disc 400, and the second probe 500 are all made of conductors, capable of conducting electrical signals. The conductive ring 200 is sleeved on the rotating shaft 100 of the pedal, the first probe 110 is disposed on the rotating shaft 100 of the pedal or on the pedal, and one end of the first probe 110 maintains contact with the conductive ring 200. The conductive disc 400 is sleeved on the output shaft of the resistance motor 600, and the second probe 500 is disposed on one side of the output shaft of the resistance motor 600 or on the inner side of the crank 700. One end of the crank 700 is provided with the rotating shaft 100 of the pedal, and the other end of the crank 700 is connected to the output shaft of the resistance motor 600. One end of the second probe 500 maintains contact with the conductive disc 400. One of the conductive ring 200 and the first probe 110 is electrically connected to the electrode on the foot pedal, and the other is electrically connected to the conductive disc 400 or the second probe 500. The parts of the conductive disc 400 and the second probe 500 that are not electrically connected to the second probe 500 or the conductive ring 200 are electrically connected to the electronic control system within the device. It will be understood that in some embodiments, the conductive disc 400 can be replaced by the conductive ring 200, and the first probe 110 and the second probe 500 can be replaced by a wreath made of conductor that can be placed on the conductive ring 200.

[0026] This electrical conduction structure solves the problem of difficult electrical connection at the rotating connection between the crank 700 and the resistance motor 600 and the pedal shaft 100 by abutting the probe with the annular conductive disc 400 or the conductive ring 200. When the user steps on the pedal to move, the probe will slide along the conductive disc 400 or the conductive ring 200 along with the pedal to form a sliding conductive structure, so that the electrical signal at the pedal can be transmitted along the crank 700 of the pedal to the main body of the device through the probe and the conductive ring 200 or the conductive disc 400. It is understandable that the first sliding conductive structure composed of the first probe 110 and the conductive ring 200 and the second sliding conductive structure composed of the second probe 500 and the conductive disc 400 can be electrically connected through wires or metal sheets. The wires or metal sheets between the two sliding conductive structures can be set inside the crank 700, thereby preventing the pedals from being electrically connected to the electronic control system inside the device body through leaking wires, preventing the wires from being entangled on the pedal shaft 100 during exercise and fitness, and also preventing the wires from frequently rubbing against other structures as the pedals move during long-term use, causing wear and leakage. The electrical conductive structure can be hidden inside the device, improving the user experience, extending the product life and improving safety during use.

[0027] Reference Figure 1 、 Figure 2 and Figure 4 In this embodiment, a conductive ring 200 is fixedly mounted on a foot pedal, which is rotatably connected to a rotating shaft 100 via a bearing. A first probe 110 is disposed within the rotating shaft 100. The rotating shaft 100 is fixedly connected to one end of a crank 700, the other end of which is connected to the output shaft of a resistance motor 600. A conductive disc 400 is fixedly mounted on a bracket 610 of the resistance motor 600 via a conductive disc support 410. A second probe 500 is fixedly mounted on the inside of the crank 700. The conductive ring 200 is electrically connected to electrodes on the foot pedal, and the conductive disc 400 is electrically connected to the electronic control system within the device body. When a user steps on the foot pedal to exercise, the conductive ring 200 rotates with the foot pedal relative to the rotating shaft 100. During this rotation, the first probe 110 slides along the inside of the conductive ring 200. Simultaneously, the second probe 500 rotates with the crank 700 relative to the conductive disc 400 fixed to the bracket 610, causing the second probe 500 to slide along the outside of the conductive disc 400. It is understandable that the connection and relative position relationship between the first probe 110 and the conductive ring 200 can be reversed, and the connection and relative position relationship between the second probe 500 and the conductive disc 400 can be reversed, that is, in some embodiments, the first probe 110 can be fixedly set in the pedal, the conductive ring 200 can be fixedly set on the rotating shaft 100, the second probe 500 can be fixedly set on the bracket 610, and the conductive disc 400 can be fixedly set on the crank 700. Figure 1 In this embodiment, the first probe 110 is electrically connected to the second probe 500 through a connecting line 300 made of an electric wire. The connecting line 300 is fixedly arranged on the inner side of the crank 700 to prevent the connecting line 300 from rubbing against other structures during movement.

[0028] Reference Figures 1 to 4In this embodiment, to prevent the probes from excessively wearing out and changing in length after long-term use, which could lead to poor contact, the first probe 110 is slidably mounted within the rotating shaft 100 via a first probe holder 111, and the second probe 500 is slidably mounted on the inner side of the crank 700 via a second probe holder 510. The first probe holder 111 is mounted within the rotating shaft 100, and the first probe 110 can slide along a slideway within the first probe holder 111 in a direction perpendicular to the rotating shaft 100. An elastic member is disposed between the end of the first probe 110 facing away from the conductive ring 200 and the rotating shaft 100. The elastic member applies an outward force perpendicular to the rotating shaft 100 to the first probe 110, ensuring that the first probe 110 maintains contact with the inner surface of the conductive ring 200. The second probe seat 510 is set on the inner side of the end of the crank 700 connected to the output shaft of the resistance motor 600. The second probe 500 can slide along the slideway in the second probe seat 510 in a direction parallel to the output shaft of the resistance motor 600. An elastic member is set between the end of the second probe 500 facing away from the conductive disc 400 and the crank 700. The elastic member applies a force perpendicular to the conductive disc 400 to the second probe 500, so that the second probe 500 can maintain contact with the outer side of the conductive ring 200. The elastic member can be a compression spring or an elastic rubber pad. Figure 6 In this embodiment, the diameter of the middle portion of the first probe 110 and the second probe 500 is wider than that of the two ends to improve the strength of the probe and facilitate the elastic member to apply thrust to the probe. The elastic member can be mounted on the narrower diameter portion of the first probe 110 and the second probe 500 facing away from the conductive ring 200 or the conductive disc 400.

[0029] The fitness equipment of the embodiment of the present invention includes the above-mentioned electric conduction structure, pedals, resistance motor 600 and control system. The pedals are connected to the output shaft of the resistance motor 600 through the rotating shaft 100 and the crank 700, and the electrodes on the pedals are connected to the control system through the electric conduction structure. The fitness equipment can be a walking machine, an elliptical machine or a spinning bike. The resistance motor 600 applies a certain amount of resistance to the pedals, so that the user needs to use a certain amount of extra force to step on the pedals to achieve the effect of exercise and fitness. Figure 1 In this embodiment, the fitness equipment is an elliptical machine, and a conductive silicone pad 800 made of conductive silicone is provided on the foot pedal. The conductive silicone pad 800 serves as an electrode and is electrically connected to the conductive ring of the electric conduction structure through the internal wires.
