For rowing machines that can generate electricity, although energy conversion is achieved, the design of their power generation devices is too complicated and not user-friendly.

[0021] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0022] The utility model provides a self-generating transmission structure for a rowing machine, such as Figures 1 to 3 As shown, it includes a power mechanism, a transmission mechanism, a resistance mechanism and a generator 6; the power mechanism is fixedly installed on the rowing machine, and the rowing movement of the human body provides power for the power mechanism; the transmission mechanism is connected between the power mechanism and the resistance mechanism, and the transmission mechanism is rotatably installed on the rowing machine and is located on one side of the power mechanism; the generator 6 is transmission-connected to the transmission mechanism, or the generator 6 is transmission-connected to the power mechanism.

[0023] In this embodiment, when the user performs rowing exercise, the power generated by the user is transmitted to the power mechanism, which is connected to the resistance mechanism (not shown in the figure) through a simple transmission mechanism. When the user adjusts the resistance of the resistance mechanism, the power mechanism can immediately and accurately feedback the resistance change, bringing the user a more comfortable exercise experience. The user can choose to connect the generator 6 to the transmission mechanism or to connect the generator 6 to the power mechanism according to the needs, which is a humanized design.

[0024] Furthermore, it also includes a one-way bearing, which is arranged on the transmission mechanism, and the transmission mechanism transmits power to the resistance mechanism in one direction through the one-way bearing. In this embodiment, a one-way bearing (not shown in the figure) is arranged on the transmission mechanism to ensure that when the power of the power mechanism is transmitted to the transmission mechanism, the transmission mechanism can only transmit the power to the resistance mechanism in one direction. In addition, the one-way bearing used in this embodiment also simplifies the design structure. The one-way bearing can replace other complex mechanical devices or control systems to achieve the same function, and can also reduce manufacturing costs and improve system reliability.

[0025] like Figure 1 and Figure 2As shown, the transmission mechanism includes a driving pulley group 2, a main belt 3, a driven pulley group 4 and a driven wheel group 5. The driving pulley group 2 is connected to the driven pulley group 4 through the main belt 3, the driven pulley group 4 is coaxially connected to the driven wheel group 5, and the driven wheel group 5 is transmission-connected to the generator 6. The driving pulley group 2 drives the generator 6 to rotate and generate electricity through the main belt 3, the driven pulley group 4 and the driven wheel group 5.

[0026] The active belt pulley group 2 of this embodiment is connected to the driven belt pulley group 4 through the main belt 3. The diameters of the active belt pulley group 2 and the driven belt pulley group 4 can be adjusted according to the needs, and the speed of the driven belt pulley group 4 can be adjusted more flexibly. And compared with the direct connection method, the active belt pulley group 2 and the driven belt pulley group 4 are connected through the main belt 3, which can reduce the vibration or noise generated during power transmission to a certain extent, which is conducive to reducing mechanical wear and improving the comfort during exercise. The driven belt pulley group 4 is coaxially connected to the driven wheel group 5, and the driven wheel group 5 is transmission-connected to the generator 6, ensuring that the power of the driven wheel pulley group can be accurately transmitted to the driven wheel group 5, and further transmitted to the generator 6, reducing the loss of power transmission.

[0027] like Figure 1 and Figure 2 As shown, the driven wheel set 5 further includes a generator belt 7, and the driven wheel set 5 is connected to the rotating shaft of the generator 6 through the generator belt 7. In this embodiment, the generator belt 7 is directly connected to the rotating shaft of the generator 6, which has a simple structure, can be easily repaired or replaced when a fault or wear occurs, and the manufacturing cost is relatively low. The generator belt 7 directly drives the rotating shaft of the generator 6 to rotate to realize the power generation of the generator 6, making the power generation process more reliable.

[0028] Furthermore, the number of the driving belt pulley group 2 , the main belt 3 , the driven belt pulley group 4 and the driven wheel group 5 are respectively one or more mutually matching ones, and the number of the generators 6 matches the number of the driven wheel group 5 .

[0029] In this embodiment, the active belt pulley group 2 can be coaxially matched with the power mechanism and set to one or more (not shown in the figure), so that the power of the power mechanism can be transmitted to one or more active belt pulley groups 2. Accordingly, the number of the main belt 3, the driven belt pulley group 4 and the driven wheel group 5 is one or more that match the active belt pulley group 2, and the number of the generator 6 matches the number of the driven wheel group 5. In this way, the power generated by the power mechanism can be transmitted to the generator 6 through one or more active belt pulley groups 2, matched with the corresponding number of main belts 3, driven belt pulley groups 4 and driven wheel groups 5. Each generator 6 can be connected to different peripherals, thereby enriching the functionality of the rowing machine and making the design more user-friendly.

[0030] like Figure 1As shown, the driven pulley group 4 of the transmission mechanism is coaxially connected to the driven wheel group 5 through a one-way bearing, and the driven pulley group 4 drives the driven wheel group 5 to rotate in one direction. The driven pulley group 4 of this embodiment is coaxially connected to the driven wheel group 5 through a one-way bearing, so that the power of the driven pulley group 4 can only be transmitted to the driven wheel group 5 in one direction, and the driven wheel group 5 rotates in one direction, and the generator 6 connected to the driven wheel group 5 also rotates in one direction. Since the rowing motion of the human body is a reciprocating motion, the rotation of the generator 6 is a one-way rotation, and the power generation process is intermittent. In another embodiment of the utility model, the one-way bearing is arranged between the active belt pulley group 2 of the power mechanism and the transmission mechanism, and the other settings are still consistent with those described above, but no further details are given.

[0031] Furthermore, it also includes a one-way bearing, which is arranged between the power mechanism and the transmission mechanism, and the power of the power mechanism is transmitted to the transmission mechanism in one direction through the one-way bearing. In this embodiment, a one-way bearing (not shown in the figure) is arranged between the power mechanism and the transmission mechanism to ensure that the power mechanism can only transmit power to the resistance mechanism in one direction. The one-way bearing used in this embodiment not only simplifies the design structure, but also reduces the manufacturing cost and improves the reliability of the system.

[0032] Furthermore, the power mechanism includes a traction member, a driving wheel 1, a scroll spring group and a generator active belt pulley 8 for cooperating with the human body's rowing movement. The traction member is connected to the driving wheel 1 to drive the driving wheel 1 to rotate. The driving wheel 1 is connected to the transmission mechanism. One end of the scroll spring group is fixed at the axis of the driving wheel 1, and the other end is fixed to the inner wall of the driving wheel 1. The generator active belt pulley 8 is fixedly sleeved on the outer periphery of the driving wheel 1. The generator belt 7 is connected to the generator 6. The traction member drives the generator 6 to rotate and generate electricity through the driving wheel 1 and the generator belt 7.

[0033] The traction member (not shown in the figure) of this embodiment is used to cooperate with the rowing movement of the human body. The traction member is wound around the driving wheel 1, and a spiral spring group is arranged inside the driving wheel 1. When the user exercises through the traction member, power can be generated and transmitted to the driving wheel 1, and the outer periphery of the driving wheel 1 is fixedly sleeved with the main belt 3 of the generator 6, and the column belt pulley of the generator 6 is connected to the generator 6 in a transmission connection. When the user drives the driving wheel 1 to rotate through the traction member, the spiral spring group (not shown in the figure) is twisted, and the generator belt 7 drives the generator 6 to rotate forward to generate electricity; when the user releases the traction member, the spiral spring group drives the driving wheel 1 to rotate in the opposite direction under the action of the torsion force, and the generator belt 7 drives the generator 6 to rotate in the opposite direction to generate electricity, so the rotation of the generator 6 is bidirectional, and the power generation process is continuous. The generator belt 7 of this embodiment is connected to the generator 6 through the generator belt 7, and different settings can also be used in other embodiments.

[0034] like Figure 2 As shown, the transmission mechanism is provided with an active belt pulley set 2, and the driving wheel 1 of the power mechanism is coaxially connected to the active belt pulley set 2 of the transmission mechanism through a one-way bearing, and the driving wheel 1 drives the active belt pulley set 2 to rotate in one direction. The driving wheel 1 of this embodiment is coaxially connected to the active belt pulley set 2 through a one-way bearing (not shown in the figure). Since the rowing exercise is a reciprocating process when the user releases the traction member, this design ensures that the driving wheel 1 will not drive the active belt pulley to rotate. On the one hand, the recovery process of the driving wheel 1 is faster, and on the other hand, the power of the driving wheel 1 can be fully transmitted to the generator 6 through the active belt pulley set 2, and the power generation is more efficient.

[0035] Furthermore, it also includes a control panel 10 and an electronic meter, wherein the control panel 10 is electrically connected to the generator 6 and the electronic meter respectively, so as to transmit electric energy and data to the electronic meter. Figure 1 and Figure 2 The control panel 10 of the present embodiment is electrically connected to the generator 6 via the connecting line 9. In addition to real-time monitoring of the working status of the generator 6 to ensure that it operates within a normal parameter range, the control panel 10 can also transmit relevant data parameters to an electronic table (not shown in the figure) for display to facilitate user viewing.

[0036] The use process of the utility model is as follows:

[0037] When the generator 6 is connected to the transmission mechanism, the user drives the driving wheel 1 to rotate through the traction member, the volute spring group is twisted, and the driving wheel 1 transmits power to the active pulley group 2 and the driven pulley group 4. Since the driven pulley group 4 is connected to the driven pulley group 5 through a one-way bearing, and the driven pulley group is connected to the generator 6, the generator 6 can only rotate in one direction; when the user releases the traction member, the volute spring group drives the driving wheel 1 to rotate in the opposite direction under the action of the torsion force. Since a one-way bearing is set between the driven pulley group 4 and the driven pulley group 5, the driven pulley group 5 will not rotate in the opposite direction with the driving wheel 1, so the generator 6 will not rotate. Therefore, when the generator 6 is connected to the transmission mechanism, the generator 6 rotates in one direction, and the power generation is intermittent.

[0038] When the generator 6 is connected to the power mechanism by transmission, the user drives the drive wheel 1 to rotate through the traction member, the volute spring group is twisted, and the outer periphery of the drive wheel 1 is fixedly sleeved with the main belt 3 of the generator 6. The main belt 3 of the generator 6 drives the generator 6 to rotate forward to generate electricity. Since the drive wheel 1 is connected to the active belt pulley group 2 through a one-way bearing, the power of the drive wheel 1 can be transmitted to the resistance mechanism through the transmission mechanism at this time; when the user releases the traction member, the volute spring group drives the drive wheel 1 to rotate in the opposite direction under the action of the torsion force, and the generator belt 7 drives the generator 6 to rotate in the opposite direction to generate electricity. Since a one-way bearing is set between the drive wheel 1 and the active belt pulley group 2, the transmission mechanism will not rotate in the opposite direction with the drive wheel 1 at this time. Therefore, when the generator 6 is connected to the power mechanism by transmission, the generator 6 rotates in both directions, and the power generation process is continuous.

[0039] The directional terms mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0040] The above description is only a preferred embodiment of the present utility model and is not a limitation on the design of the present case. Any equivalent changes made based on the key design of the present case shall fall within the protection scope of the present case.
