[0022] See also Figures 1 to 3 The embodiment of the present application provides a non-powered surfing machine 10, which includes a body 100, a swing rod 200, a first connecting rod 300 and a surfing assembly 400. The body 100 is fixedly arranged, and the swing rod 200 and the surfing assembly 400 are respectively movably connected to the body 100.

[0023] The body 100 is a fixed component in the non-powered surfing machine 10, and is used to install, position, and connect other components or assemblies in the non-powered surfing machine 10, such as the swing rod 200, the surfing assembly 400, etc. The structure, shape, size, etc. of the body 100 are not limited, and can be flexibly adjusted according to the design requirements of the non-powered surfing machine 10. Specifically, the body 100 includes a base 110 and a second column 120 inclined to the base 110, and a slide rail 111 is arranged on the base 110. The second column 120 is arranged inclined to the base 110, that is, the longitudinal extension direction of the second column 120 is not parallel to the longitudinal extension direction of the base 110, so that the structure of the body 100 can be more stable, and it can also play a better connection and support role for other components in the non-powered surfing machine 10. The base 110 is provided with a slide rail 111 for the surfing assembly 400 to slide, and the position and length of the slide rail 111 can be flexibly adjusted according to the sliding requirements of the sliding assembly. In some embodiments, the entire base 110 may be composed of the slide rail 111, so that the sliding range of the surfing component 400 is larger.

[0024] One end of the first connecting rod 300 is rotatably connected to the second column 120, and the other end of the first connecting rod 300 is rotatably connected to the swing rod 200. In this way, the user can push and pull the swing rod 200 to make the swing rod 200 and the body 100 move relative to each other, so that the user's hands can be exercised. By adjusting the connection position of the first connecting rod 300 and the second column 120, the connection position of the first connecting rod 300 and the swing rod 200, and the length of the first connecting rod 300, the range of movement of the swing rod 200 relative to the second column 120 can be changed. In some embodiments, Figure 2 and Figure 3 As shown, the first connecting rod 300 can swing around the second column 120 and the swing rod 200 within a certain angle range, that is, the first connecting rod 300 and the swing rod 200 always remain on the same side of the second column 120 during the movement relative to the second column 120. The rotation connection between the first connecting rod 300 and the second column 120 and the swing rod 200 can be achieved through the hinge seat, that is, the first connecting rod 300 is connected to the second column 120 and the swing rod 200 respectively by means of the hinge seat.

[0025] The surfing assembly 400 is used to simulate surfing motion so as to facilitate the user's experience and exercise. Specifically, one end of the surfing assembly 400 is rotatably connected to the swing rod 200, and the other end of the surfing assembly 400 is provided with a sliding portion 410 matching the slide rail 111, and the sliding portion 410 is provided on the slide rail 111 and can slide along the slide rail 111. The surfing assembly 400 can generate relative motion with the machine body 100 through the sliding portion 410, and the user can make the surfing assembly 400 and the machine body 100 generate relative motion by stepping on the surfing assembly 400, so that the user's legs are exercised, and the user's full-body exercise needs are met, and the use effect is good. In addition, one end of the surfing assembly 400 is rotatably connected to the swing rod 200, so the swing rod 200 and the surfing assembly 400 are linked, and the surfing assembly 400 will also be driven by the swing rod 200 when sliding along the slide rail 111, so that the surfing assembly 400 can better simulate the surfing motion, and there is no need to provide an additional power source for the surfing assembly 400, which is convenient to use.

[0026] Based on the non-powered surfing machine 10 of the embodiment of the present application, by making the two ends of the first connecting rod 300 rotatably connected to the second column 120 and the swing rod 200 respectively, the user can push and pull the swing rod 200 to make the swing rod 200 and the body 100 produce relative movement, so that the user's hands can be exercised. At the same time, the surfing component 400 is provided with a sliding part 410 that matches the slide rail 111 on the base 110. The surfing component 400 can produce relative movement with the body 100 through the sliding part 410. The user can step on the surfing component 400 to make the surfing component 400 and the body 100 produce relative movement, so that the user's legs can be exercised, thereby meeting the user's needs for full-body exercise and having a good use effect. Furthermore, one end of the surfing component 400 is rotatably connected to the pendulum rod 200, so the pendulum rod 200 and the surfing component 400 are linked, and the surfing component 400 will also be driven by the pendulum rod 200 when sliding along the slide rail 111, so that the surfing component 400 can better simulate the surfing movement, and there is no need to provide an additional power source for the surfing component 400, which is easy to use.

[0027] In order to facilitate the user to push the swing rod 200 to move, in some embodiments, the number of the swing rod 200 and the first connecting rod 300 are both two, the two swing rods 200 are arranged side by side and spaced apart, and the two first connecting rods 300 are rotatably connected to the second column 120 and the two swing rods 200 respectively. Providing two swing rods 200 is convenient for the user to hold them with both hands, which is more convenient to use. Figure 1As shown, the two swing rods 200 can also be symmetrically arranged on both sides of the second column 120, which is conducive to the user to maintain body balance when pushing the swing rod 200 to move. It should be noted that when in use, the two swing rods 200 can be kept in synchronous motion so that the non-powered surfing machine 10 can better simulate the state of surfing. Therefore, further, in some embodiments, the non-powered surfing machine 10 also includes a handlebar 500, one end of the handlebar 500 is provided with a gripping portion 510, and the other end of the handlebar 500 is detachably connected to the two swing rods 200. The two swing rods 200 are connected by the handlebar 500. On the one hand, it is convenient for the user to hold the gripping portion 510 and push and pull the two swing rods 200 at the same time, and on the other hand, the two swing rods 200 can be kept in synchronous motion, which brings a better user experience. One or more recessed portions or clamping portions that match the user's fingers or wrists can be provided on the gripping portion 510 to increase the comfort of the user when holding.

[0028] The surfing assembly 400 is provided with a sliding portion 410 that matches the slide rail 111 on the base 110. The surfing assembly 400 can generate relative motion with the body 100 through the sliding portion 410. Specifically, in some embodiments, the surfing assembly 400 includes a second connecting rod 420 and a support rod 430. One end of the second connecting rod 420 is rotatably connected to the swing rod 200, and the support rod 430 is arranged at the other end of the second connecting rod 420 and is inclined with the second connecting rod 420. The support rod 430 is provided with a sliding portion 410. That is, the surfing assembly 400 is slidably connected to the slide rail 111 through the sliding part 410 on the support rod 430, and the surfing assembly 400 is rotatably connected to the swing rod 200 through the second connecting rod 420. The support rod 430 and the second connecting rod 420 are arranged obliquely, that is, the longitudinal extension direction of the support rod 430 is not parallel to the longitudinal extension direction of the second connecting rod 420. In this way, the structure of the surfing assembly 400 can be more stable, the support member can better support the second connecting rod 420, and the sliding movement of the sliding part 410 along the guide rail and the rotation movement of the second connecting rod 420 around the swing rod 200 can be carried out simultaneously. Figure 2 and Figure 3 As shown, in some embodiments, the second connecting rod 420 and the supporting rod 430 are arranged perpendicular to each other. The sliding part 410 can be a pulley, and a slide groove is provided on the pulley. The pulley is sleeved on the slide rail 111 through the slide groove and can slide along the slide rail 111.

[0029] Similarly, in order to better achieve synchronous movement of the surfing assembly 400 and the swing bar 200, in some embodiments, the number of the second connecting rod 420 and the supporting rod 430 are both two, the two second connecting rods 420 are arranged side by side and spaced apart, and the two second connecting rods 420 are respectively rotatably connected to the two swing bars 200, and the two supporting rods 430 are respectively arranged at the other end of the second connecting rod 420. The two second connecting rods 420 are arranged to facilitate the user to step on them with both legs, which is more convenient to use. Figure 1 As shown, the two second connecting rods 420 can also be symmetrically arranged on both sides of the second column 120, which is helpful for the user to maintain body balance when the foot-operated surfing assembly 400 is moving.

[0030] As described above, when in use, the two swing rods 200 in the non-powered surfing machine 10 keep synchronous movement, so that the non-powered surfing machine 10 can better simulate the state of surfing. In order to maintain the consistency of movement with the swing rod 200, and in order to make the swing rod 200 better perform synchronous movement, the two second connecting rods 420 in the surfing assembly 400 also need to keep synchronous movement. Therefore, in some embodiments, the surfing assembly 400 also includes a surfboard 440, which is arranged across the two second connecting rods 420, and the surfboard 440 is fixedly connected to the surface of the second connecting rod 420 away from the support rod 430. The two second connecting rods 420 are fixedly connected by the surfboard 440, which is convenient for the user to drive the two second connecting rods 420 to move at the same time by stepping on the surfboard 440, and on the other hand, the two second connecting rods 420 can keep synchronous movement, giving the user a better use experience. In addition, the surfboard 440 can be a surfboard 440 used in actual surfing, so as to give the user a more realistic surfing experience.

[0031] In the process of using the non-powered surfing machine 10, in order to make the movement of the swing rod 200 and the surfing assembly 400 more stable, in some embodiments, the non-powered surfing machine 10 further includes a crank 600, one end of the crank 600 is rotatably connected to the machine body 100, and the other end of the crank 600 is rotatably connected to the swing rod 200. In this way, during the rotation of the swing rod 200, the end of the crank 600 connected to the swing rod 200 can be driven by the swing rod 200 to make a rotational motion around the end of the crank 600 connected to the machine body 100. With this arrangement, the swing rod 200 is rotatably connected to the machine body 100 at one end through the first connecting rod 300, and the swing rod 200 is rotatably connected to the machine body 100 at the other end through the crank 600. Therefore, the connection between the swing rod 200 and the machine body 100 is more stable, and the swing rod 200 is more stable when swinging around the machine body 100.

[0032] At the same time, in order to make the swing bar 200 and the surfing assembly 400 have a more coherent and uniform motion process, in some embodiments, the non-powered 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 that is rotatably connected to the body 100 is also in transmission connection with the input end 710, the output end 720 is rotatably connected to the flywheel 800, and the flywheel 800 is rotatably connected to the body 100, so that the crank 600 can drive the flywheel 800 to rotate. In this way, when the crank 600 rotates, it can drive the flywheel 800 to rotate through the transmission effect of the transmission system 700, and the flywheel 800 can store the energy and inertia of the crank 600 during rotation. The flywheel 800 has a large moment of inertia. Since the process of the user pushing the swing rod 200 to move is discontinuous, the swing rod 200 drives the crank 600 to rotate in a discontinuous manner. Therefore, the rotation speed of the crank 600 also changes. When the rotation speed of the crank 600 increases, the kinetic energy of the flywheel 800 increases, and the energy is stored; when the rotation speed of the crank 600 decreases, the kinetic energy of the flywheel 800 decreases, and the energy is released. Therefore, the flywheel 800 can be used to reduce the speed fluctuation of the crank 600 during rotation, so that the rotation of the crank 600 remains uniform, which makes the swing process of the swing rod 200 more uniform and has a certain degree of continuity, thereby improving the user experience.

[0033] The transmission system 700 is used to transmit power between the crank 600 and the flywheel 800. The crank 600 is connected to the input end 710 of the transmission system 700 to transmit power to the transmission system 700. After being transmitted at various levels in the transmission system 700, the output end 720 of the transmission system 700 is connected to the flywheel 800 to transmit power to the flywheel 800. The transmission methods of the transmission system 700 include chain transmission, friction transmission, hydraulic transmission, gear transmission, belt 740 transmission, etc. Correspondingly, the transmission system 700 can be a chain transmission system, a friction transmission system, a hydraulic transmission system, a gear transmission system, a belt transmission system, etc. Figure 2 and Figure 3 As shown, in one embodiment, the transmission system 700 further includes a plurality of transmission wheels 730, each transmission wheel 730 being transmission-connected between the input end 710 and the output end 720. Each transmission wheel 730 is transmission-connected to the input end 710 and the output end 720 via 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 in different use scenarios.

[0034] like Figure 2As shown, specifically, 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 the first rotating shaft, and the first transmission wheel 730 among the four transmission wheels 730 is transmission-connected to the crank 600 through the first rotating shaft, and the first transmission wheel 730 can be driven by the crank 600 to rotate around the machine body 100. The second transmission wheel 730 is transmission-connected to the first transmission wheel 730 through the belt 740, and at the same time, the second transmission wheel 730 is also rotationally connected to the machine body 100 through the second rotating shaft, and the second transmission wheel 730 can be driven by the first transmission wheel 730 to rotate around the machine body 100. The third transmission wheel 730 is also rotatably connected to the machine body 100 through the second rotating shaft, so the third transmission wheel 730 can be driven by the second transmission wheel 730 to rotate around the machine body 100. In order to facilitate the installation and distribution of the second transmission wheel 730 and the third transmission wheel 730, the second transmission wheel 730 and the third transmission wheel 730 can be respectively located on both sides of the machine body 100, and the second transmission wheel 730 and the third transmission wheel 730 are respectively sleeved on the two ends of the second rotating shaft. The fourth transmission wheel 730 is transmission-connected to the third transmission wheel 730 through the belt 740. At the same time, the fourth transmission wheel 730 is also rotatably connected to the machine body 100 through the third rotating shaft, and the flywheel 800 is also rotatably connected to the machine body 100 through the third rotating shaft, so the fourth transmission wheel 730 can be driven to rotate by the third transmission wheel 730, and the flywheel 800 can be driven to rotate by the fourth transmission wheel 730. Similarly, in order to facilitate the installation and distribution of the fourth transmission wheel 730 and the flywheel 800, the fourth transmission wheel 730 and the flywheel 800 can be respectively located on both sides of the body 100, and the fourth transmission wheel 730 and the flywheel 800 are respectively sleeved on the two ends of the third rotating shaft. Finally, through the transmission effect of the four transmission wheels 730 in the transmission system 700, the crank 600 can drive the flywheel 800 to rotate. Among them, the diameters of the second transmission wheel 730 and the third transmission wheel 730 are different. The second transmission wheel 730 and the third transmission wheel 730 are coaxially connected and rotated, so the angular velocity of the second transmission wheel 730 and the third transmission wheel 730 when rotating is the same, but because their diameters are different, the movement speeds of the belts 740 driven by the second transmission wheel 730 and the third transmission wheel 730 are different, which also achieves the effect of changing the ratio of the rotation speed of the flywheel 800 and the rotation speed of the crank 600.

[0035] When used, by Figures 2 to 3, the user pulls the swing rod 200, so that the swing rod 200 drives the first connecting rod 300 to rotate counterclockwise relative to the body 100 in the figure. At this time, the end of the swing rod 200 connected to the surfing component 400 moves to the upper left in the figure relative to the body 100. At the same time, the swing rod 200 drives one end of the surfing component 400 to move to the upper left in the figure relative to the body 100, and the other end of the surfing component 400 moves to the lower left in the figure relative to the body 100. In addition, the surfing component 400 slides to the left in the figure relative to the body 100 along the slide rail 111 through the sliding part 410. Similarly, by Figure 3 to Figure 2 , the user pushes the swing rod 200, so that the swing rod 200 drives the first connecting rod 300 to rotate clockwise relative to the body 100 in the figure. At this time, the end of the swing rod 200 connected to the surfing component 400 moves to the lower right relative to the body 100 in the figure. At the same time, the swing rod 200 drives one end of the surfing component 400 to move to the lower right relative to the body 100 in the figure, and the other end of the surfing component 400 moves to the upper right relative to the body 100 in the figure. In addition, the surfing component 400 slides to the right relative to the body 100 in the figure along the slide rail 111 through the sliding part 410. It should be noted that Figure 2 and Figure 3 What is shown is only a schematic diagram of the state of the non-powered surfing machine 10 provided by one embodiment of the present application at two different positions during the movement, and does not represent the extreme position of the non-powered surfing machine 10 during the movement.

[0036] In summary, the non-powered surfing machine 10 in the present application makes the two ends of the first connecting rod 300 rotatably connected to the second column 120 and the swing rod 200 respectively. In this way, the user can push and pull the swing rod 200 to make the swing rod 200 and the body 100 produce relative movement, so that the user's hands can be exercised. At the same time, the surfing component 400 is provided with a sliding part 410 that matches the slide rail 111 on the base 110. The surfing component 400 can produce relative movement with the body 100 through the sliding part 410. The user can step on the surfing component 400 to make the surfing component 400 and the body 100 produce relative movement, so that the user's legs can be exercised, thereby meeting the user's full-body exercise needs and having a good use effect. Furthermore, one end of the surfing component 400 is rotatably connected to the pendulum rod 200, so the pendulum rod 200 and the surfing component 400 are linked, and the surfing component 400 will also be driven by the pendulum rod 200 when sliding along the slide rail 111, so that the surfing component 400 can better simulate the surfing movement, and there is no need to provide an additional power source for the surfing component 400, which is easy to use.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
