Furthermore, as shown in fig. 1, two second links 420 can be symmetrically disposed on two sides of the upright 120, which is beneficial for the user to keep his body balance when the foot surfing assembly 400 is moving.

As described above, in use, the two rockers 200 in the unpowered surfer 10 are kept in synchronized motion so that the unpowered surfer 10 can better simulate the state of surfing. In order to keep the pendulum 200 consistent with the movement and to make the pendulum 200 better perform the synchronous movement, the two second links 420 in the surfing assembly 400 also need to keep the synchronous movement, therefore, in some embodiments, the surfing assembly 400 further comprises a surfboard 440, the surfboard 440 straddles the two second links 420, and the surfboard 440 is fixedly connected with the surfaces of the second links 420, which are away from the supporting bar 430.

In order to stabilize the movement of the pendulum 200 and thus the surfing component 400 during use of the unpowered surfer 10, in some embodiments, the unpowered surfer 10 further comprises a crank 600, one end of the crank 600 is rotatably connected to the body 100, and the other end of the crank 600 is rotatably connected to the pendulum 200. Thus, in the rotation process of the swing rod 200, the end of the crank 600 connected to the swing rod 200 can rotate around the end of the crank 600 connected to the machine body 100 under the driving of the swing rod 200. With such an arrangement, the swing link 200 is rotatably connected to the machine body 100 at one end through the first connecting rod 300, and the swing link 200 is rotatably connected to the machine body 100 at the other end through the crank 600, so that the connection between the swing link 200 and the machine body 100 is more stable, and the swing link 200 is more stable when swinging around the machine body 100.

Meanwhile, in order to make the swing link 200 and the surfing component 400 have more consistent and uniform motion processes, in some embodiments, the unpowered surfing machine 10 further includes a transmission system 700 and a flywheel 800, the transmission system 700 has an input end 710 and an output end 720, one end of the crank 600 rotatably connected to the machine body 100 is further rotatably connected to the input end 710, the output end 720 is rotatably connected to the flywheel 800, and the flywheel 800 is rotatably connected to the machine body 100, so that the crank 600 can drive the flywheel 800 to rotate. Thus, when the crank 600 rotates, the flywheel 800 can be driven to rotate by the transmission function of the transmission system 700, and the flywheel 800 can store energy and inertia in the rotation process of the crank 600. The flywheel 800 has larger rotational inertia, and because the process that the user pushes the swing rod 200 to move is discontinuous, the process that the swing rod 200 drives the crank 600 to rotate is also discontinuous, so the rotating speed of the crank 600 is also changed, and when the rotating speed of the crank 600 is increased, the kinetic energy of the flywheel 800 is increased, and the energy is stored; when the rotational speed of the crank 600 is reduced, the kinetic energy of the flywheel 800 is reduced, releasing the energy. Therefore, the flywheel 800 can be used for reducing the speed fluctuation of the crank 600 in the rotating process, so that the rotation of the crank 600 is kept uniform, the swinging process of the swing rod 200 is more uniform, certain continuity is achieved, and the use experience of a user is improved.

The transmission system 700 is used for power transmission between the crank 600 and the flywheel 800, the crank 600 is connected with the input end 710 of the transmission system 700, power is transmitted into the transmission system 700, and after being transmitted through each stage in the transmission system 700, the output end 720 of the transmission system 700 is connected with the flywheel 800, and power is transmitted to the flywheel 800. The transmission mode of the transmission system 700 includes chain transmission, friction transmission, hydraulic transmission, gear transmission, belt 740 transmission, and correspondingly, the transmission system 700 may be chain transmission, friction transmission, hydraulic transmission, gear transmission, belt transmission, and the like. As shown in fig. 2 and 3, in one embodiment, the transmission system 700 further includes a plurality of transmission wheels 730, and each transmission wheel 730 is drivingly connected between the input end 710 and the output end 720. Each transmission wheel 730 is in transmission connection with the input end 710 and the output end 720 through a belt 740. The transmission system 700 has a transmission ratio, and by changing the transmission ratio of the transmission system 700, the ratio of the rotation speed of the flywheel 800 to the rotation speed of the crank 600 can be changed to meet the use requirements under different use scenes.

Specifically, as shown in fig. 2, in some embodiments, the number of the transmission wheels 730 is four, wherein one end of the crank 600 is rotatably connected to the machine body 100 through a first rotating shaft, and the first transmission wheel 730 of the four transmission wheels 730 is rotatably connected to the crank 600 through the first rotating shaft, so that the first transmission wheel 730 can be driven by the crank 600 to rotate around the machine body 100. The second driving wheel 730 is in transmission connection with the first driving wheel 730 through a belt 740, and meanwhile, the second driving wheel 730 is also in rotational connection with the machine body 100 through a second rotating shaft, so that the second driving wheel 730 can be driven by the first driving wheel 730 to rotate around the machine body 100.

Similarly, in order to facilitate the installation and distribution of the fourth driving wheel 730 and the flywheel 800, the fourth driving wheel 730 and the flywheel 800 may be respectively located at two sides of the machine body 100, and the fourth driving wheel 730 and the flywheel 800 are respectively sleeved at two ends of the third rotating shaft. Finally, the crank 600 can drive the flywheel 800 to rotate through the transmission action of the four transmission wheels 730 in the transmission system 700. Wherein, the diameters of the second driving wheel 730 and the third driving wheel 730 are different. The second driving wheel 730 and the third driving wheel 730 are coaxially connected and rotate, so that the angular velocities of the second driving wheel 730 and the third driving wheel 730 during rotation are the same, but the diameters of the second driving wheel 730 and the third driving wheel 730 are different, so that the movement velocities of the belts 740 respectively driven by the second driving wheel 730 and the third driving wheel 730 are different, and the effect of changing the ratio of the rotation speed of the flywheel 800 to the rotation speed of the crank 600 is also realized.
