[0039] In this embodiment, the power generation mechanism includes a first sheet metal component 10, a generator 12, a first belt 14, and a voltage stabilizing module 16. One end of the first belt 14 is mounted on the rotor of the generator 12, and the other end is mounted on a pulley 204. The voltage stabilizing module 16 is electrically connected to the generator 12. When the main shaft 202 rotates, the main shaft 202 drives the pulley 204, which in turn drives the first belt 14. The first belt 14 transfers kinetic energy to the rotor, which in turn drives the generator 12 to generate electricity. This enables the rowing machine to generate electricity, saving electricity and being more environmentally friendly and energy-efficient.

[0040] Furthermore, in some embodiments of the present invention, the variable resistance magnetic disk assembly includes: a fixed bracket 262, the fixed bracket 262 is fixedly connected to the first base plate 244, the fixed bracket 262 is provided with a groove, and the fixed bracket 262 is provided with a plurality of fourth through holes; a line motor 264, the line motor 264 is connected to the first base plate 244, and the line motor 264 is electrically connected to the voltage stabilizing module 16; a second sheet metal part 266, the second sheet metal part 266 is provided with a plurality of connecting parts, and the plurality of connecting parts are each provided with a spring, and the second sheet metal part 266 is slidably connected to the fixed bracket 262 through the plurality of fourth through holes through the plurality of connecting parts; an aluminum magnetic disk 268, the aluminum magnetic disk 268 is connected to the rotating shaft; a magnet 270, the number of magnets 270 There are multiple magnets 270 adsorbed on the second sheet metal 266, located on the side close to the aluminum disk 268; a brake line, one end of the brake line is connected to the output end of the line motor 264, and the other end of the brake line is connected to the second sheet metal 266; a second belt 272, one end of the second belt 272 is sleeved on the other end of the rotating shaft, and the other end of the second belt 272 is sleeved on the pulley 204; a controller module, the controller module is electrically connected to the voltage stabilizing module 16, and the controller module is electrically connected to the rotating shaft, and the controller module is used to control the rotation of the rotating shaft and the rotation of the line motor 264; wherein, multiple magnets 270 are evenly distributed on the second sheet metal 266, and the spring is located at one end of the multiple connecting parts close to the second sheet metal 266.

[0041] In this embodiment, the variable resistance magnetic disk assembly includes a fixed bracket 262, a linear motor 264, a second sheet metal member 266, an aluminum magnetic disk 268, a magnet 270, a brake cable, a second belt 272, and a controller module. When the rowing machine requires magnetic resistance, the controller module supplies power to the rotating shaft, which in turn rotates the shaft, driving the aluminum magnetic disk 268. The aluminum magnetic disk 268 and the magnet 270 generate magnetic resistance, thereby varying the resistance of the rowing machine.

[0042] When the rowing machine needs to increase the strength of the magnetic resistance, the controller module receives the instruction, and the controller sends the instruction to the voltage stabilizing module 16. The voltage stabilizing module 16 supplies power to the line motor 264 and receives the instruction.

When the second sheet metal part 266 moves, it will drive the magnet 270 to gradually move away from the aluminum disk 268, and the spring will gradually compress, thereby reducing the resistance of the magnetic resistance.

[0043] When the rowing machine stops working or reduces the magnetic resistance, the wire motor 264 no longer applies force to the second sheet metal part 266 through the brake wire, and the spring gradually rebounds, thereby driving the second sheet metal part to reset, causing the magnet 270 to gradually approach the aluminum disk 268, thereby increasing the resistance of the magnetic resistance.

[0044] The variable resistance magnetic disk assembly enables the resistance of the rowing machine to be adjusted, thereby enhancing the adaptability of the device.

[0045] It will be understood that the uniform distribution of the plurality of magnets 270 on the second sheet metal member 266 means that the number of magnets 270 located above the aluminum disk 268 and the number of magnets 270 located below the aluminum disk 268 are equal and their positions correspond to each other. The spring being located at one end of the plurality of connectors near the second sheet metal member 266 means that the connectors may partially pass through the fourth through-hole and partially not, with the spring being located in the portion of the connector that does not pass through the fourth through-hole.

[0046] Specifically, the number of the fourth through holes is the same as the number of the connecting members, and the fourth through holes are adapted to the connecting members.

[0047] Specifically, the second sheet metal part 266 is provided with a notch to facilitate the connection of the brake line.

[0049] In this embodiment, the pull cord system includes a second base plate 30, a third sheet metal member 32, a guide pulley 34, a third belt 36, and a handle. One end of the third belt 36 is connected to the main shaft 202. The third belt 36 abuts against the guide pulley 34, changing its direction, thereby facilitating user exertion and enhancing the user experience.

[0050] Furthermore, the pulley 204 is connected to the second base plate 30 via a bearing, which can reduce the noise generated when the rowing machine is in use and reduce wear between devices.

[0051] Furthermore, in some embodiments of the present invention, a slide rail 40 is connected to the water tank support frame 220; a sliding seat is slidably connected to the slide rail 40; an inclined plate 42 is connected to the water tank support frame 220 at one end and to the second bottom plate 30 at the other end, and a foot pedal is provided on the inclined plate 42; a knob 44 is connected to the inclined plate 42, and the knob 44 is electrically connected to the controller module, a second cavity is provided inside the knob 44, and the controller module is located in the second cavity; wherein, rotating the knob 44 can change the magnetic resistance level.

[0052] In this embodiment, the sliding seat allows the user to mobilize muscles throughout the body, and the sliding seat is combined with the foot pedals to enhance the user experience.

[0053] On this basis, by turning the knob 44, the size of the magnetic resistance, that is, the magnetic resistance level, can be changed, thereby completing the adjustment of the resistance. The knob 44 is more convenient and easier to improve the user experience.
