Description

Technical Field

[0001] This specification relates to the field of fitness equipment, and in particular to a resistance module and its installation structure. Background Art

[0002] While meeting people's needs for better health and fitness, fitness equipment is constantly evolving and innovating. Among these, motor-powered weight training stations, as well as wind-resistance rowing machines, ski machines, and exercise bikes, are becoming increasingly important components of the modern fitness industry. Weight training stations are multifunctional equipment that combine free weights with machine training. They typically consist of an adjustment mechanism, a pull mechanism, and a bench press bar, allowing users to target different body parts. Rowing machines, on the other hand, utilize wind resistance technology to simulate rowing motions, effectively strengthening upper body muscles and cardiovascular function. Wind resistance provides a realistic rowing experience, while allowing users to adjust training intensity by varying rowing speed and force. Ski machines are another widely used piece of fitness equipment that simulates skiing. Their distinctive design features a ski board and handlebars. Stepping and pushing and pulling the handles simulate the uphill and downhill movements of skiing, thereby strengthening whole-body muscles and improving aerobic endurance.

Figure 2 1 is an exemplary internal structure diagram of a resistance module according to some embodiments of this specification. Figure 3 This is an exemplary partial structural diagram of a resistance module and fitness equipment according to some embodiments of this specification.

[0035] In some embodiments, as Figure 1-3 As shown, the resistance module 100 includes a housing 110, a power device 120, and a transmission mechanism 130. In some embodiments, the transmission mechanism 130 includes a connecting shaft 131, which can be used for transmission connection with various fitness equipment 200. The power device 120 can provide resistance to the fitness equipment 200 via the connecting shaft 131. In some embodiments, the fitness equipment 200 can include, but is not limited to, a strength training station, a rowing machine, a ski machine, etc.

[0036] The housing 110 is the outer shell of the resistance module 100. The housing 110 supports other components of the resistance module 100 and protects the internal components of the resistance module 100. The housing 110 can be made of metal, plastic, or other materials with sufficient strength to support the internal components of the resistance module 100.

[0037] In some embodiments, a handle 111 is provided on the exterior of the housing 110, and a fixing plate 112 is provided within the housing 110. The handle 111 facilitates the user's lifting of the resistance module 100 for installation on various fitness equipment 200. The fixing plate 112 is used to mount components within the resistance module 100. In some embodiments, the power device 120 and the transmission mechanism 130 can be mounted on the fixing plate 112. A cooling fan 113 is provided on the fixing plate 112 to dissipate heat from the resistance module 100.

[0038] The power device 120 is a device that can provide mechanical or electrical energy to the resistance module 100. In some embodiments, the power device 120 includes a motor assembly 121, a resistor 122, and a controller 123. The motor assembly 121 is used to provide resistance to the fitness equipment 200.

[0039] In some embodiments, the motor assembly 121 may be composed of a motor stator, a magnet, a motor rotor, and an encoder. The resistor 122 is used to adjust the output of the motor assembly 121, and the magnitude of the output may correspond to the magnitude of the resistance provided by the resistance module 100 to the fitness equipment 200. In some embodiments, the resistor 122 may include a metal resistor, a cement resistor, or a combination thereof. The controller 123 may control parameters such as the output and speed of the motor assembly 121, thereby controlling the resistance provided to the fitness equipment 200. The controller 123 may also be used to process data from at least one component of the resistance module 100 or an external data source. In some embodiments, the controller 123 may include a central processing unit (CPU), an application-specific integrated circuit (ASIC), or any combination thereof.

[0040] In some embodiments, the power device 120 further includes a power supply. The power supply can be a plug-in power supply or a battery. The battery can include a rechargeable battery 124. The plug-in power supply includes a power switch 125 and a power interface 126. The power interface 126 is connected to an external power source via a power cord. The power switch 125 is used to start and stop the motor assembly 121.

[0041] The transmission mechanism 130 is a mechanism that transmits power from the power device 120 to the fitness equipment 200. In some embodiments, the transmission mechanism 130 includes a positioning shaft 201, which enables the connecting shaft 131 to be concentric with the rotation axis of the frame of the fitness equipment 200. The end of the positioning shaft 201 can be provided with shaft teeth, and the end of the connecting shaft 131 can be provided with shaft teeth that match the positioning shaft 201, so that the positioning shaft 201 can mesh with the connecting shaft 131.

[0042] In some embodiments, as Figure 3 As shown, the connecting shaft 131 may include a sleeve for inserting the positioning shaft 201. The end of the connecting shaft 131 may be provided with shaft teeth. The outer side of the positioning shaft 201 may be provided with a shaft gear sleeve 202 that matches the connecting shaft 131. Therefore, after the positioning shaft 201 is inserted into the connecting shaft 131, the shaft teeth and the shaft gear sleeve 202 achieve tooth meshing. In some embodiments, the positioning shaft 201 may be a component fixedly mounted on the frame of the fitness equipment 200.

[0043] In some embodiments of this specification, a transmission mechanism 130 is provided so that after the resistance module 100 is connected to the fitness equipment 200 via the connecting shaft 131, the resistance module 100 is started, and the rotating shaft of the frame of the fitness equipment 200 moves synchronously with the connecting shaft 131, thereby providing resistance for the user's fitness training.

[0044] The resistance modules provided in some embodiments of this specification combine functions such as power supply and resistance adjustment into a modular resistance module. The modular resistance module can be connected to different fitness equipment via a connecting shaft. The connecting shaft can be further aligned with the rotation axis of the fitness equipment frame via a positioning shaft, thereby effectively providing resistance for different fitness equipment. For example, the resistance module is connected to different frames such as rowing machines, ski machines, and integrated strength training stations, replacing traditional systems such as wind damping, water damping, magnetic damping, and weight counterweights to provide power to users. Users can adjust training intensity and resistance as needed, making training more flexible and personalized. The resistance module can be connected to a variety of different fitness equipment, which can also save users costs. Multiple fitness equipment frames only need to be equipped with a set of resistance modules to obtain a variety of fitness equipment, greatly reducing user costs.

[0045] The resistance module's handles facilitate both lifting and pushing, and its power source can be rechargeable, making it easy to swap between different equipment. The module's cooling fan, resistors, and controller all provide excellent support for its performance. The module's gear meshing and positioning shaft ensure a secure transmission connection between the module and the fitness equipment, allowing it to be used with a variety of different fitness equipment.

[0046] In some embodiments, the resistance module 100 further includes a conical structure. The conical structure can be disposed outside the connecting shaft 131. In some embodiments, the conical structure can mate with a mating structure provided on the fitness equipment 200, aligning the connecting shaft 131 with the rotation axis of the frame of the fitness equipment 200. The conical structure further assists in aligning the connecting shaft 131 with the rotation axis. During the alignment process between the resistance module 100 and the fitness equipment 200, the conical structure and the mating structure cooperate to guide the connecting shaft 131 of the resistance module 100 and the rotation axis of the fitness equipment 200 to be concentric, thereby facilitating alignment.

[0047] In some embodiments, a through slot can be provided at an easily observable portion of the conical structure (such as the top or side), through which the user can observe the engagement. The material of the conical structure can also be transparent plastic to facilitate user observation. In some embodiments, a scale is also provided on the conical structure to indicate the engagement distance of the shaft teeth and whether the engagement depth is met. The scale can be provided at the location of the through slot, so that the user can observe the engagement and the engagement distance at the same time, thereby further improving the convenience of user observation.

[0048] The cone structure is further described below with reference to the accompanying drawings. Figure 4a 1 is an exemplary structural diagram of a cone structure according to some embodiments of this specification. Figure 4b It is an exemplary structural diagram of the engagement of conical surface structures according to some embodiments of this specification.

[0049] For example, Figure 4a and Figure 4b As shown, the conical structure includes an outer conical component 410 and an inner conical component 420. The outer conical component 410 is arranged around the outside of the connecting shaft 131, and the inner conical component 420 is arranged around the outside of the shaft gear sleeve 202. The outer side surface 411 of the outer conical component 410 is an inclined surface, and the inner side surface 421 of the inner conical component 420 is an inclined surface. The outer side surface 411 of the outer conical component 410 and the inner side surface 421 of the inner conical component 420 are matched in inclination angle, that is, along the a direction, the diameter of the outer side surface 411 of the outer conical component 410 gradually decreases, and the diameter of the inner side surface 421 of the inner conical component 420 gradually increases, so that the outer side surface 411 of the outer conical component 410 and the inner side surface 421 of the inner conical component 420 can fit together. When the resistance module 100 is close to the fitness equipment 200, the outer conical component 410 is far away from the inner conical component 420 (such as Figure 4a As shown in FIG, the resistance module 100 and the fitness equipment 200 approach each other, and due to the guidance of the conical structure, the connecting shaft 131 of the resistance module 100 and the shaft gear sleeve 202 of the fitness equipment 200 will gradually move toward the axis, and easily achieve concentricity; when the shaft teeth of the resistance module 100 and the shaft gear sleeve 202 are engaged, the outer conical surface component 410 and the inner conical surface component 420 are also in contact (as shown in FIG. Figure 4b As shown), the meshing positioning and concentricity are completed.

[0050] In some embodiments, the length of the outer conical component 410 and the inner conical component 420 can be greater than the positioning length of the positioning shaft 201; before the positioning shaft 201 is positioned, the conical structure can assist in the positioning of the positioning shaft 201, thereby improving the convenience of the positioning shaft 201 being inserted.

[0051] Figure 5 This is an exemplary structural diagram of a resistance module and fitness equipment according to some embodiments of this specification. Figure 6 It is an exemplary structural diagram of the installation structure shown in some embodiments of this specification.

[0052] Some embodiments of this specification provide a mounting structure for a resistance module 100 that can be mounted on a fitness device 200. The resistance module 100 can be fixed relative to the fitness device 200 via the mounting structure. It is understood that the mounting structure can be determined based on the structural characteristics of the fitness device 200.

[0053] In some embodiments, as Figure 5 and Figure 6 As shown, the fitness equipment can be a rowing machine 300, and the mounting structure is provided on the rowing machine 300, and the mounting structure includes a fixing frame 310, a fixing plate 320 and a rotating shaft 330. The fixing frame 310 is provided with three support plates matching the resistance module 100, and the fixing frame 310 is used to support the resistance module 100 from at least three directions. The fixing plate 320 is used to define the position of the resistance module 100, and the fixing plate 320 can rotate along the rotating shaft 330. In some embodiments, the resistance module 100 is fixed by placing the resistance module 100 into the fixing frame 310, rotating the fixing plate 320 along the rotating shaft 330, rotating it to a position that fits the resistance module 100, and then connecting the fixing plate 320 to the fixing frame 310 to complete the installation. The connection method may include a snap connection, a pin connection, a threaded connection, etc.

[0054] Figure 7 This is an exemplary structural diagram of a resistance module and another fitness equipment according to some embodiments of this specification. Figure 8 It is an exemplary structural diagram of the installation structure shown in some embodiments of this specification.

[0055] Figure 9a is an exemplary structural diagram of a first positioning component according to some embodiments of this specification. Figure 9b is another exemplary structural diagram of the first positioning component shown in some embodiments of this specification. Figure 9c is another exemplary structural diagram of the first positioning component shown in some embodiments of this specification.

[0056] In some embodiments, as Figure 7 and Figure 8 As shown, the mounting structure includes a first positioning assembly 210 and a second positioning assembly 220. Figures 9a to 9cAs shown, the first positioning assembly 210 includes an L-shaped pressure plate 211. The end of the transverse plate of the L-shaped pressure plate 211 is provided with a hook structure 212 for hooking the resistance module 100 to prevent the resistance module 100 from moving outward; the transverse plate of the L-shaped pressure plate 211 can press the resistance module 100 so that it does not move upward; the longitudinal plate of the L-shaped pressure plate 211 is used to facilitate the user to pull. In some embodiments, the L-shaped pressure plate 211 is penetrated by a torsion spring 213. The elastic force of the torsion spring 213 can apply a downward force to the transverse plate of the L-shaped pressure plate 211, further pressing the resistance module 100. In some embodiments, when the user pulls the L-shaped pressure plate 211 upward, the hook structure 212 can be lifted to a certain angle and separated from the resistance module 100.

[0057] Figure 10a is an exemplary structural diagram of a second positioning component according to some embodiments of this specification.

[0058] Figure 10b is another exemplary structural diagram of the second positioning component shown in some embodiments of this specification.

[0059] Figure 10c is an exemplary structural diagram of a convex plate according to some embodiments of this specification.

[0060] like Figures 10a to 10c As shown, the second positioning assembly 220 includes a convex plate 221 and a mounting groove 222. One side of the convex plate 221 is flat, and the other side has a protrusion (such as Figure 10c The protruding plate 221 is rotatably disposed in the mounting groove 222. For example, a pin 223 is passed through the protruding plate 221, and both ends of the pin 223 are fixed in the mounting groove 222, so that the protruding plate 221 can rotate based on the pin 223.

[0061] In some embodiments, as Figure 10a The raised plate 221 can be rotated until its plane is coplanar with the plane of the notch of the mounting slot 222, and can remain stable in this position when no force is applied to rotate it. In this case, the fitness equipment 200 is not equipped with the resistance module 100 or the resistance module 100 is not restrained. In some embodiments, due to the distribution of gravity on the raised plate 221, i.e., the raised side has a greater weight, the raised plate 221 can maintain its plane coplanar with the plane of the notch of the mounting slot 222.

[0062] In some embodiments, as Figure 10b As shown, the convex plate 221 can be rotated until the protrusion of the convex plate 221 exceeds the surface where the notch of the installation groove 222 is located, and can remain stable in this state when there is no force pushing it to rotate. At this time, the resistance module 100 is stuck by the protrusion of the convex plate 221 to achieve stable installation (see Figure 8In some embodiments, because the protrusion of the protruding plate 221 is stuck to the resistance module 100 , under the interaction force between the resistance module 100 and the protrusion, the protruding plate 221 can maintain the state of protruding beyond the surface where the notch of the mounting groove 222 is located.

[0063] In some embodiments, the second positioning assembly 220 also includes a small motor (not shown in the figure), which can be connected to the convex plate 221 to drive the convex plate 221 to rotate, so that the user does not need to operate manually, but can operate by controlling the small motor, which is more convenient.

[0064] In some embodiments of this specification, a mounting structure matching the resistance module is provided on the fitness equipment so that the resistance module and the fitness equipment are relatively fixed, thereby ensuring that the resistance module can be in good contact with the fitness equipment during operation and the resistance can be well transmitted to the fitness equipment.

[0065] In some embodiments, the resistance module 100 further includes a position sensor. The position sensor is used to monitor whether the resistance module 100 has reached a preset installation position. The position sensor may include a first position sensor and a second position sensor. The first position sensor is provided on the resistance module 100 and is used to monitor the position of the transmission mechanism 130. The second position sensor is provided on the fitness equipment 200 and is used to monitor the position of the mounting structure. In some embodiments, the position sensor further includes a third position sensor for identifying the type of fitness equipment connected thereto. The position sensor can be of various types, such as a capacitive sensor, a displacement sensor, a grating sensor, and a position encoder. In some embodiments, the position sensor can be in communication with the controller 123, and the controller 123 can perform further processing based on the monitoring results of the position sensor.

[0066] In some embodiments, the first position sensor and the third position sensor may be Hall sensors. Hall sensors may be provided at different locations on different fitness equipment 200. The Hall sensors can detect positions, and based on the detected positions, the controller 123 can identify the type of fitness equipment 200 connected to the resistance module 100. For example, based on the detected positions, the controller 123 can identify whether the fitness equipment 200 connected to the resistance module 100 is a strength training station or a rowing machine.

[0067] In some embodiments, the resistance module 100 may also include an interactive screen. An interactive screen is a device that interacts with the user, allowing the user to control the resistance module 100 or the fitness equipment 200 by touching the screen, clicking buttons, entering text, dragging icons, and so on. In some embodiments, the interactive screen may be located on at least one of the resistance module 100 and the fitness equipment 200. In other embodiments, the interactive screen may be a smart device (e.g., a smartphone or smartwatch) that is in communication with the resistance module 100 or the fitness equipment 200.

[0068] In some embodiments, the resistance module further includes a distance sensor, which is used to monitor the distance between the end face of the connecting shaft 131 and the end face of the rotating shaft of the frame of the fitness equipment 200 .

[0069] In some embodiments, the controller 123 can respond to the type of fitness equipment 200 connected to the identified resistance module 100 and the fact that the distance between the end face of the connecting shaft 131 and the end face of the rotating shaft of the frame of the fitness equipment 200 shown by the distance sensor data does not meet a preset condition, and provide a reminder on the interactive screen that the connecting shaft 131 is not properly installed. In some embodiments, the controller 123 can respond to the reminder that the connecting shaft 131 is not properly installed by displaying a corresponding installation video or the scale position on the conical structure on the interactive screen to help the user install it. In some embodiments, the controller 123 can repeatedly monitor the distance sensor data based on a preset time interval until the distance sensor data meets a preset condition. The preset condition can be that the distance between the end face of the connecting shaft 131 and the end face of the rotating shaft of the frame of the fitness equipment 200 is less than a distance threshold. The distance threshold can be preset based on experience, and the distance threshold can be 0.

[0070] In some embodiments, the controller 123 can, in response to the detection data from the first and second position sensors satisfying a preset condition, indicate that the resistance module 100 has reached the preset installation position. Based on this, the controller 123 can send a start command to activate the power device 120 of the resistance module 100. In some embodiments, in response to the detection data from the first and second position sensors failing to satisfy the preset condition, the controller 123 can indicate the specific details of the non-satisfaction, including the components and locations that are not properly installed. Based on the specific details of the non-satisfaction, the controller 123 can provide installation instructions, such as displaying a video of the corresponding component installation on the interactive screen. The preset condition can be pre-set based on experience or historical data. For example, if the current detection data from the first and second position sensors are consistent with the corresponding detection data from the first and second position sensors in historical data when the resistance module 100 was properly installed, the preset condition can be considered satisfied.

[0071] In some embodiments, the controller 123 can respond to the resistance module 100 replacing the fitness equipment 200 (for example, the resistance module 100 is separated from a certain fitness equipment 200 and is close to or connected to another fitness equipment 200) by providing installation instructions or fitness training instructions for the resistance module 100 of the replaced fitness equipment 200 on the interactive screen.

[0072] In some embodiments of this disclosure, the provision of position sensors, distance sensors, and an interactive screen can help users identify the type of connected fitness equipment and provide timely installation guidance, thereby providing convenient installation. Furthermore, the controller 123, by evaluating the position and distance sensor data, ensures that the resistance module is securely installed and positioned before activating it, ensuring user safety during use.

[0073] In some embodiments, the position sensor also includes a fourth position sensor for monitoring the status data of the fitness equipment 200. In some embodiments, when the fitness equipment 200 is a strength training station, the status data may include the position of the pivot arm of the strength training station and the corresponding exercise program, the speed at which the drawstring is pulled out, the length of the drawstring pulled out, etc. In some embodiments, when the fitness equipment 200 is a rowing machine, the status data may include the exercise program of the rowing machine, the speed at which the drawstring is pulled out, the length of the drawstring pulled out, etc. The exercise program refers to exercise data related to exercise, and the exercise data may include fitness parameters, exercise duration, and effective exercise time, etc. For more description of exercise data, see the following content.

[0074] In some embodiments, controller 123 can prompt a change of exercise program and change the resistance provided by resistance module 100 in response to status data exceeding a preset value. In some embodiments, different exercise modes correspond to different power equipment parameters (e.g., speed, output power, etc.) of resistance module 100, and these power equipment parameters can be preset values. In some embodiments, controller 123 can obtain power equipment parameters in advance based on the order of exercise mode switching in historical records.

[0075] In some embodiments, the controller 123 can activate the resistance module 100 based on the preset (post-switching) power equipment parameters in response to the motor assembly stopping when the fitness equipment 200 is switched. In some embodiments, preset conditions must be met before activating the resistance module 100. For details on the preset conditions that must be met before activation, please refer to the above description.

[0076] In some embodiments, in response to the resistance module 100 being connected to at least one set of fitness equipment 200, the controller 123 can collect user exercise data from the fitness equipment 200, determine recommended fitness parameters, and display them on the interactive screen. The at least one set of fitness equipment 200 refers to one or more different fitness equipment 200 that can be connected to the resistance module 100. The exercise data may include fitness parameters, exercise time, and other parameters. Fitness parameters include tension, torque, resistance, and other parameters of the fitness equipment.

[0077] In some embodiments, when the resistance module 100 is connected to different fitness equipment 200, the controller 123 can obtain exercise data for the corresponding fitness equipment 200. In some embodiments, the exercise data can also include exercise duration and effective exercise time. Exercise duration can refer to the time a user spends exercising. Effective exercise time can refer to the time it takes for a user to achieve the best results from their exercise. In some embodiments, effective exercise time can refer to the duration of the resistance output by the resistance module 100, excluding situations where the resistance module 100 is operating but not outputting resistance.

[0078] In some embodiments, after the resistance module 100 and fitness equipment 200 are connected, the controller 123 can determine the effective exercise time based on the exercise intensity data of the corresponding fitness equipment 200. In some embodiments, the effective exercise time can be calculated through a weighted calculation based on the exercise duration. At standard exercise intensity, the weight is 1; at intensity levels below the standard intensity, the weight is less than 1; conversely, the weight is greater than 1. Exercise intensity data indicates the intensity of exercise, reflecting the amount of force applied during exercise and the degree of physical tension. Exercise intensity data can include data such as the start-up time of the fitness equipment 200 or the start-up time of the resistance module 100, as well as data such as the resistance output and power consumption recorded by the resistance module 100 at different time points. In some embodiments, the standard exercise intensity can be associated with user characteristics. For example, the standard exercise intensity can be lowered for beginners and increased for regular exercisers. In some embodiments, the standard exercise intensity is based on the number of times the resistance module 100 has been switched on and the historical effective exercise time of the user within a preset time period. For example, the user switched the resistance module 100 three times in the past hour, and the effective exercise time after each switch was close to 20 minutes, indicating that the user exercised seriously; then, when the user exercises subsequently, the standard exercise intensity will be reduced, so that the user will be recorded with more effective exercise time.

[0079] In some embodiments of the present disclosure, by recording exercise data of the resistance module 100 connected to different fitness equipment 200, the user's exercise data on different fitness equipment 200 can be obtained, thereby better customizing the user's exercise to meet the user's exercise needs.

[0080] In some embodiments, the controller 123 can display recommended fitness parameters to the user on the interactive screen based on the exercise data. The exercise data includes historical and currently recorded exercise data. The recommended fitness parameters include parameters such as tension, torque, and resistance of fitness equipment recommended to the user. In some embodiments, the recommended exercise parameters of the resistance module 100 can be gradual, gradually increasing the intensity until the effective exercise time changes below a preset time threshold or decreases (indicating that the current exercise intensity may be too high for the user), at which point the intensity increase stops.

[0081] In some embodiments, the recommended fitness parameters are related to the user's effective exercise time and standard exercise time. In some embodiments, the standard exercise time is related to user characteristics (for example, user characteristics counted when the user logs in). For example, if the user's effective exercise time is lower than the standard exercise time, the recommended fitness parameters are adjusted to lower the exercise intensity, and the percentage of reduction = effective exercise time / standard exercise time. For example, if the user's effective exercise time is higher than the standard exercise time, the recommended fitness parameters are adjusted to increase the exercise intensity, and the percentage of increase = effective exercise time / standard exercise time. In some embodiments, when the difference between the effective exercise times of the current and subsequent users is less than a threshold value, the recommended fitness parameters are no longer adjusted.

[0082] In some embodiments of this specification, by continuously optimizing the user's recommended fitness parameters, the matching degree between the recommended fitness parameters and the user can be improved, thereby improving the user's exercise effect, while also avoiding exercise injuries caused by excessive exercise intensity.

[0083] In some embodiments, the controller 123 can predict the user's optimal fitness parameters using a fitness parameter prediction model in response to the resistance module 100 being connected to the fitness equipment 200, and send the predictions to the interactive screen for display. The optimal fitness parameters are the fitness parameters that best match the user.

[0084] In some embodiments, the fitness parameter prediction model may be a machine learning model. For example, the fitness parameter prediction model may include any one or combination of a convolutional neural network (CNN) model, a neural network (NN) model, or other customized model structures.

[0085] The input of the fitness parameter prediction model includes user characteristics, current fitness equipment and candidate fitness parameters; the output includes the recommendation degree of the candidate fitness parameters. User characteristics can be obtained when the user logs in online through the terminal, for example, they can be input by the user himself. Candidate fitness parameters can be multiple groups of fitness parameters determined by matching the user characteristics and the current fitness equipment through a preset fitness parameter database. For example, the controller 123 can construct a retrieval vector (such as {user characteristics 1, fitness equipment A}) based on the user characteristics and the current fitness equipment, search in the fitness parameter vector database, and select the fitness parameters corresponding to the standard vector with the closest distance (such as cosine distance) to the retrieval vector as the candidate fitness parameters. The fitness parameter vector database can be a vector database established by collecting historical data to construct vectors.

[0086] In some embodiments, the controller 123 may generate sequence data based on the number of times the resistance module 100 has been swapped between different fitness equipment 200 devices in a recent time period, the type of fitness equipment 200 swapped each time, and the corresponding effective exercise time after each swap. The controller 123 may then match candidate fitness parameters based on the sequence data. For example, a user may only exercise on a single type of fitness equipment 200 each day. As the workout progresses, the user may need a higher intensity. In this case, the candidate fitness parameters that are subsequently matched may be appropriately increased. For another example, if the user's effective exercise time is long before switching between the resistance module 100 and fitness equipment 200, after the user switches between fitness equipment 200, the candidate fitness parameters that are subsequently matched may be appropriately reduced to avoid excessive fatigue. The recommendation level of a candidate fitness parameter refers to the degree to which the candidate fitness parameter matches the user. The recommendation level of a candidate fitness parameter can be expressed in a variety of ways, for example, using a range of values ​​from 0 to 100%.

[0087] In some embodiments, a fitness parameter prediction model can be trained using multiple labeled training samples. For example, multiple labeled training samples can be input into an initial fitness parameter prediction model. A loss function can be constructed using the labels and the results of the initial fitness parameter prediction model. Based on the loss function, the parameters of the initial fitness parameter prediction model are iteratively updated using gradient descent or other methods. Model training is completed when preset conditions are met, resulting in a trained fitness parameter prediction model. The preset conditions may include convergence of the loss function, a number of iterations reaching a threshold, and the like.

[0088] In some embodiments, the training sample may include at least sample user features, sample current fitness equipment, and sample candidate fitness parameters. The label may be the recommendation degree corresponding to the above-mentioned sample candidate fitness parameters. In some embodiments, the controller 123 may obtain labels in a variety of ways. For example, the user's feedback on the interactive screen after the exercise is completed (such as actively popping up an evaluation page). For another example, based on a large amount of historical data, when the difference in the effective exercise time of the two users is less than a threshold, it indicates that the current fitness parameters are suitable. When obtaining labels through user feedback on the interactive screen, it can be considered that the label for a good review is 1, and the label for a non-good review (medium review / bad review) is 0. When obtaining labels based on historical data, the label for a suitable fitness parameter can be 1, and the label for an unsuitable fitness parameter can be 0.

[0089] In some embodiments, the controller 123 may, based on the recommendation scores of the candidate fitness parameters output by the fitness parameter prediction model, select the one with the highest recommendation score as the optimal fitness parameter to be displayed to the user. In some embodiments, the controller 123 may also recommend multiple candidate fitness parameters in order; those ranked lower in order with lower recommendation scores may be marked with prompts such as "maybe too low intensity" or "may have a risk of strain" to further satisfy the user's preferences.

[0090] In some embodiments of this specification, by determining optimal fitness parameters and combining the optimal parameters with user characteristics, an exercise plan that matches the user is further obtained to improve the user's exercise effect.
