[0030] As Figures 1 to 5 shown: A rowing machine includes: a frame body 1, a bracket 2, a wind resistance flywheel 3, a seat 4, a foot pedal assembly 5, a pulling rope 6, and a handle 7;
[0031] The frame body 1 is arranged on the bracket 2. The frame body 1 includes a horizontally arranged guide rail section 11 and a support section 12 provided on one side of the guide rail section 11; the wind resistance flywheel 3 is arranged on the support section 12, and a guide rail is provided on the guide rail section 11, and the seat 4 is arranged on the guide rail section 11 and moves along the guide rail;
[0032] One end of the pulling rope 6 is arranged inside the wind resistance flywheel 3, and the other end is connected to the handle 7;
[0033] Two foot pedal assemblies 5 are arranged on both sides of the guide rail section 11. The foot pedal assembly 5 includes an upper pedal 51, a force measuring plate 52, a fixing plate 53, and a housing 54 arranged in sequence from top to bottom. The fixing plate 53 and the housing 54 form a closed accommodation space, and a pressure sensor 55 is arranged inside the accommodation space. A through hole 531 for the pressure sensor 55 to pass through is provided on the fixing plate 53. One end of the pressure sensor 55 is arranged on the force measuring plate 52, and the other end is arranged on the fixing plate 53.
[0034] During use, move the seat 4 to one side close to the wind resistance flywheel 3. The user sits on the seat 4, places both feet on the pedal assembly, and holds the handle 7. At this time, the legs are in a bent state; the legs exert force and slowly straighten, causing the seat 4 to move to the side away from the wind resistance flywheel 3, and the upper body tilts slightly backward, using the core muscles for support to complete one stroke. Repeat the above actions to achieve the purpose of training.
[0035] By installing the pressure sensor 55 in the foot pedal assembly 5, it is possible to accurately measure the foot force exerted by the user during rowing, capture the mechanical changes of the feet at different stages, and provide more detailed force data for the user.
[0036] Since it can accurately measure and record the foot force, the device can automatically adjust the training plan according to the specific situation of the user (such as uneven strength, insufficient force, etc.), or provide suggestions, which is particularly useful for athletes, rehabilitation patients who need targeted training, or ordinary users who hope to improve the training effect.
[0037] By monitoring the foot force, users can more clearly understand their own force application methods, and through adjustment, achieve a better exercise posture, reduce unnecessary stress, thereby reducing the risk of injury. At the same time, uniform force application and correct posture help improve the exercise effect, especially in enhancing leg and core strength.
[0038] For users undergoing rehabilitation training, the accurate measurement of foot force is particularly important. Through real-time monitoring and feedback, small improvements or problems during the rehabilitation process can be promptly detected and adjusted, helping users recover better and reducing the possibility of secondary injury.
[0039] As Figure 3 shown, a schematic structural diagram of an implementation manner of the pedal assembly 5. The pressure sensor 55 adopts a simple installation method. By processing the fixing plate 53 and the force measuring plate 52 into relatively complex shapes, the effect of measuring the foot force during rising can be achieved. However, for the integrated structures of the fixing plate 53 and the force measuring plate 52, the structures of the fixing plate 53 and the force measuring plate 52 are complex, increasing the processing cost and difficulty of the fixing plate 53 and the force measuring plate 52, resulting in an increase in processing cost. Therefore, the following improvements are made:
[0040] As Figure 4 、 5 shown, a schematic structural diagram of another implementation manner of the pedal assembly 5. It further includes a base 56 provided on the fixing plate 53. The base 56 is provided with a cavity structure 561 with an opening on one side. At the opening of the cavity structure 561, a flange structure 562 is also provided. The flange structure 562 is provided on the fixing plate 53 and is coaxially arranged with the through hole 531. Specifically, the base 56 and the sensor can be screwed together or connected in other ways. The sensor can be first installed in the base 56, and then the base 56 is installed on the fixing plate 53. This solution simplifies the structure of the fixing plate 53, reduces the processing cost of the fixing plate 53, and at the same time facilitates the installation of the sensor.
[0041] The cavity structure 561 of the above base 56 is not only used to fix the sensor, but also can provide additional protection for the sensor. The design of the cavity structure 561 helps to avoid the direct influence of the external environment (such as dust, moisture, etc.) on the sensor, reduce the risk of damage, and thus extend the service life of the sensor and the entire rowing machine.
[0042] As a preference of the above embodiment, continue to refer to Figure 4 、 Figure 5, a connecting member 57 is provided between the force measuring plate 52 and the pressure sensor 55. The connecting member 57 is detachably connected to the pressure sensor 55, and between the force measuring plate 52 and the connecting member 57. Specifically, the connecting member 57 can be screwed to the pressure sensor 55, and between the force measuring plate 52 and the connecting member 57, or other connection methods can also be used; during installation, the connecting member 57 can be installed on the pressure sensor 55, and then the force measuring plate 52 is connected to the connecting member 57, which can facilitate the installation, disassembly and maintenance of the sensor more conveniently.
[0043] The above-mentioned connecting member 57 can provide an additional protective layer, reduce the direct impact of the force measuring plate 52 on the sensor, extend its service life, and at the same time reduce the processing requirements and processing difficulty of the force measuring plate 52.
[0044] In this embodiment, at least one pressure sensor 55 is provided in each foot pedal assembly 5. In this embodiment, in order to measure force more evenly, two pressure sensors are provided, one corresponding to the sole area and one corresponding to the heel area. Specifically, by respectively arranging the pressure sensors 55 in the sole and heel areas, the force exerted by different parts of the user during rowing can be captured more accurately. The system can obtain more detailed mechanical data and analyze the force distribution of the feet during the rowing action, so as to more accurately evaluate the user's exercise state and technical level.
[0045] Among them, an adjusting plate 58 is provided on the upper pedal 51. One end of the adjusting plate 58 is provided with a baffle structure 581 perpendicular to the upper pedal 51, and the other end is provided with a plurality of adjusting holes 582. One end of the upper pedal 51 is provided with a socket 511 and a positioning post 512. The socket 511 is arranged through the upper pedal 51 along the length direction. One end of the adjusting plate 58 passes through the socket 511, and the positioning post 512 is arranged in the adjusting hole 582 to adjust the size of the foot pedal position to suit the sizes of different people's feet. Specifically, the design of the adjusting plate 58 enables the foot pedal position to be adjusted according to the user's foot length. Through the cooperation of the adjusting plate 58 and the positioning post 512, users with different foot lengths can find a suitable foot pedal position for themselves, thus providing a more comfortable use experience. Especially for home use, it can meet the needs of different members.
[0046] Preferably, as in the above embodiments, a wireless tensiometer 10 is further provided between the handle 7 and the pull rope 6. The wireless tensiometer 10 is built with a tension sensor and an attitude sensor, and is used to measure the force, angle, and maximum acceleration during pulling. The wireless tensiometer 10 is connected to the display screen 9 or a mobile terminal by wireless means. Specifically, on the one hand, the wireless tensiometer 10 can measure in real time the force exerted by the user during the rowing motion. The accurate tension data can help the user understand their own force application situation and make adjustments according to the measurement results to achieve a more effective training effect. Accurate force measurement is very helpful for evaluating the user's physical fitness level and training progress. The attitude sensor in the wireless tensiometer 10 can not only measure the tension, but also monitor the maximum acceleration during the rowing motion. On the other hand, acceleration is an important indicator of motion efficiency and speed. By monitoring this parameter, the user can evaluate their speed control and explosive power during the rowing process, so as to optimize the training strategy.
[0047] In this embodiment, the guide rail section 11 is provided with a data collector 8, and the pressure sensor 55 is connected to the data collector 8. In this embodiment, the data collector 8 is arranged at the bottom of the guide rail section 11. The data collector 8 can also be built into the pedal assembly 5. Specifically, on the one hand, the setting of the data collector 8 centralizes the data of the pressure sensor 55 and the tension sensor into a system for management, making data collection and processing more efficient. It can collect and store the motion data from different sensors in real time and systematically, ensuring the integrity and accuracy of the information. On the other hand, it can provide a more comprehensive motion analysis, such as mechanical distribution, force application mode, and motion efficiency, etc., so as to provide more accurate training feedback. Moreover, the data collector 8 can receive and process the data from the sensors in real time, and the user can obtain the feedback of the motion state immediately during the rowing process. Real-time monitoring helps the user adjust the motion immediately, optimize the motion effect, and ensure the accuracy and safety of the training.
[0048] Among them, the data collector 8 is connected to the display screen or a mobile terminal (such as a mobile phone or a tablet, etc.) by wireless means (such as Bluetooth). Specifically, the mobile terminal can receive the motion data and feedback from the data collector 8 in real time. The user can obtain immediate training effects, progress, and adjustment suggestions through the mobile terminal during the training process, improving the interactivity and real-time nature of the training. The integration of the mobile terminal makes the user interface more intuitive and friendly. The user can view detailed data reports, charts, and analysis results through the graphical interface, making the motion data easier to understand and operate, thus enhancing the overall user experience.
[0049] Preferably, as in the above embodiments, it further includes a display screen 9 provided on the support section 12. The display screen 9 is used to display the test data after the integration of the wireless dynamometer 10 and the data collector 8. Specifically, the display screen 9 can display the integrated test data in real time, including key indicators such as tensile force, foot pressure, and acceleration. Users can view these data immediately during the training process to understand their own exercise status, adjust the training method, and thus optimize the training effect; the display screen 9 provides visual data feedback, enabling users to more intuitively understand the exercise data; the interactivity enhances the user's sense of participation and training enthusiasm, allowing users to see their progress and adjustment effects in a timely manner, increasing the fun and motivation of training.
[0050] In this embodiment, the bottom of the bracket 2 is further provided with feet 21, which are used to increase the force-bearing area between the bracket 2 and the ground, making the entire device more stable. During the rowing process, users are not easily affected by the shaking or instability of the device, so they can focus on the training movements, improving the exercise effect and training safety; at the same time, by increasing the contact area, the feet 21 reduce the pressure concentration of the device on the ground, avoiding local indentations or damage to the ground and protecting the ground from damage.
[0051] This kind of force-measuring structure is applicable not only to the air resistance type rowing machine but also to other rowing machines such as water resistance and magnetic resistance.
