[0030] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the embodiments disclosed below.

[0031] As shown in Figure 1, one embodiment of the strength training device 100 provided in this application includes a frame 10, a base 11, a traction rope assembly 12, a motor assembly 13, and an interactive panel 14. The frame 10 is used to support various components of the strength training device. The frame 10 can be constructed into any suitable structure, and the material of the frame 10 can be steel or carbon fiber, etc. The interactive panel 14 is installed on the frame 10. The motor assembly 13 is connected to the traction rope assembly 12 and is used to drive the traction rope assembly 12 to move. The interactive panel 14 is used for user interaction or to display training information. The base 11 is connected to the bottom of the frame 10. In the training state, the base 11 is laid flat on the training ground. The top of the frame 10 has a grip part 15 for the user to perform pull-up training, or the top of the frame 10 is provided with a grip part 15 for the user to perform pull-up training.

[0032] In one embodiment, the grip portion 15 is located at the highest position of the strength training device, and the grip portion 15 is configured to extend toward the end of the base 11, with the vertical projection of the grip portion 15 at least partially falling on the base 11.

[0033] Specifically, the grip 15 provided in this application can be a handle or other structure that a user can hold for pull-up training. The grip 15 can be integrally formed with the frame 10, with the grip 15 formed on the top of the frame 10; or the grip 15 can be a separate structure from the frame 10, with the grip 15 installed on the top of the frame 10.

[0034] It should be noted that the grip 15 being located at the highest position on the strength training equipment refers to its vertical height. The grip 15 is located at the top, which is designed to make full use of the height of the frame 10 to accommodate training users of different heights.

[0035] The base 11 provided in this application can be used as a footrest. When the user is training, the base 11 can be laid flat on the training ground for the user to stand or lie on. The motor assembly 13 provided in this application may include components such as a motor and a winding reel assembly.

[0036] Referring to Figure 2, in one embodiment, the traction rope assembly 12 provided in this application includes a traction rope 1201 and a binding member 1202 for attachment to a user. The binding member 1202 is connected (fixedly or detachably) to a first end of the traction rope 1201, and a motor assembly 13 is connected to a second end of the traction rope 1201. The second end of the traction rope 1201 can be wound around the motor shaft of the motor assembly 13. The traction rope 1201 can be retracted or extended by the motor in the motor assembly 13, thereby controlling the tension applied to the traction rope 1201. Optionally, the control of the motor in the motor assembly 13 can be achieved by motor drive.

[0037] The interactive panel 14 is a display device that includes a display screen and provides an interactive interface for selecting training modes. For example, the interactive interface provides a selection of multiple training modes provided in this application, and the user can select the desired training mode in the interactive interface.

[0038] Furthermore, the interactive panel 14 can also be used to control the motor to provide tension to the traction rope 1201 based on the motor control mode corresponding to the selected training mode. Different training modes correspond to different motor control modes. Under different motor control modes, the tension on the traction rope 1201 can be controlled based on different force curves, thereby providing the user with assistance or resistance according to the corresponding force curve, enriching the pull-up training modes.

[0039] The working states of the traction rope assembly 12 provided in this application include an assist working state for converting the tension of the motor into a pull-up assist for the user, and a resistance working state for converting the tension of the motor into a pull-up resistance for the user.

[0040] For example, when a user needs to perform pull-ups with assistance, the traction rope assembly 12 can be set to the assisted working state, and the binding 1202 can be attached to the body. In this state, the traction rope assembly 12 can convert the motor's pulling force into assistive pull-ups. For instance, in the assisted working state, the traction rope 1201 in the traction rope assembly 12 pulls the binding 1202 upwards (diagonally upwards), providing upward assistance to the user, making pull-up training easier. Conversely, when a user needs to perform pull-ups with resistance, the traction rope assembly 12 can be set to the resistance working state, and the binding 1202 can be attached to the body. In this state, the traction rope assembly 12 can convert the motor's pulling force into resistance, providing pull-up resistance to the user. For instance, in the resistance working state, the traction rope 1201 in the traction rope assembly 12 pulls the binding 1202 downwards (diagonally downwards), providing downward pulling force to the user, requiring more effort for pull-ups.

[0041] In one embodiment, the support 10 includes a first column 1011, a second column 1012, and a third column 1013. The tops of the first column 1011, the second column 1012, and the third column 1013 are connected to each other to form a tripod structure. A gripping part 15 is formed or disposed on the top of the tripod structure. A motor receiving cavity structure 1014 is disposed below the tripod structure, and a motor assembly 13 is disposed in the motor receiving cavity structure 1014.

[0042] Specifically, the frame 10 provided in this application includes a tripod structure, a handle 15 is disposed on the top of the tripod structure, and a motor housing structure 1014 is disposed below the tripod structure, located at the bottom of the frame 10. The tripod structure includes a first column 1011, a second column 1012, and a third column 1013. The first column 1011, the second column 1012, and the third column 1013 are parallel to each other and vertically arranged. The tops of the first column 1011 and the second column 1012 are connected to the top of the third column 1013, forming a stable triangular structure to ensure stable training for the user on the strength training equipment and to guarantee user safety.

[0043] The motor housing cavity structure 1014 can be a motor compartment, a base, or other cavity structure that can accommodate the motor assembly 13.

[0044] Referring again to Figure 1, in some embodiments, the support 10 includes a first column 1011, a second column 1012, and a third column 1013, wherein the top of the first column 1012 is connected to the top of the third column 10123, the top of the second column 1012 is connected to the top of the third column 1013, and a motor receiving cavity structure 1014 is provided at the bottom of the frame 10, and the motor assembly 13 is disposed in the motor receiving cavity structure 1014.

[0045] In one embodiment, the frame 10 includes a first column 1011 and a second column 1012. The lower ends of the first column 1011 and the second column 1012 are located on the side of the motor housing structure 1014. The upper ends of the first column 1011 and the second column 1012 are connected as one unit. A gripping portion 15 is formed between the upper ends of the first column 1011 and the second column 1012, or a gripping portion 15 is provided between the upper ends of the first column 1011 and the second column 1012.

[0046] Specifically, the motor housing structure 1014 provided in this application is disposed at the bottom of the frame 10, and the lower ends of the first column 1011 and the second column 1012 are located on both sides of the motor housing structure 1014. It can be understood that the sides of the motor housing structure 1014 can be adjacent to or close to the side of the motor housing structure 1014, or they can be the front side of the side of the motor housing structure 1014 facing the pedal 11. The gripping part 15 can be integrally formed with the first column 1011 and the second column 1012, forming a gripping part 15 between the upper ends of the first column 1011 and the second column 1012; or the gripping part 15 can be a separate structure from the first column 1011 and the second column 1012, with the gripping part 15 installed between the upper ends of the first column 1011 and the second column 1012.

[0047] It should be noted that the lower ends of the first column 1011 and the second column 1012 are located on the side of the motor housing structure 1014. This can be understood as follows: in the direction extending toward the pedal 11, the lower ends of the first column 1011 and the second column 1012 are located on both sides of the motor housing structure 1014, so that the motor housing structure 1014 is located in the space between the lower ends of the first column 1011 and the second column 1012. Alternatively, it can be understood that, compared to the vertical plane formed by the first column 1011 and the second column 1012, the motor housing structure 1014 is located on the side of the vertical plane away from the pedal 11, so that the motor housing structure 1014 and the pedal 11 are located on both sides of the vertical plane formed by the first column 1011 and the second column 1012.

[0048] The motor can be installed inside the motor housing cavity structure 1014. A winding wheel assembly for the traction rope 1201 to pass around and connect to the motor can be installed inside the motor housing cavity structure 1014. The user can stand on the pedal 11 and then grasp the handles 15 with both hands to perform pull-up training, or perform other types of training on the pedal 11.

[0049] In one embodiment, the support 10 includes at least a first column 1011 and a second column 1012. The vertical plane in which the grip portion 15 is located is closer to the end of the pedal 11 than the vertical plane formed by the first column 1011 and the second column 1012, so that the grip portion 15 remains extended toward the end of the pedal 11.

[0050] In one embodiment, the traction rope assembly 12 provided in this application further includes a pulley block 1203, which can slide up and down and is fixedly installed on the frame 10. Optionally, the pulley block 1203 can be fixed to the frame 10 by means of screws, snap rings, pins, clamping, etc. For example, multiple positioning holes can be provided on the frame 10 in the vertical direction, and locking screws can be provided on the pulley block 1203. The pulley block 1203 is fixed to the frame 10 by inserting the locking screws into the positioning holes and tightening them. The traction rope 1201 can be wound around the pulley block 1203 to achieve turning. For example, the traction rope 1201 starts from the second end, passes through the winding wheel of the motor assembly 13, extends upward to the pulley block 1203 after the winding wheel changes direction, turns and extends out at the pulley block 1203, and the first end of the traction rope 1201 extending from the pulley block 1203 can be connected to the binding member 1202. The frame 10 includes left and right uprights (i.e., the first upright 1011 and the second upright 1012). The upper part of each upright has a pulley mounting position for the assisted working state, and the lower part has a pulley mounting position for the resistance working state. A pulley assembly 1203 is fixedly installed on the pulley mounting position in the assisted working state to provide assistance for pull-ups; the pulley assembly 1203 is also fixedly installed on the pulley mounting position in the resistance working state to provide resistance for pull-ups.

[0051] Optionally, the traction rope 1201 and pulley assembly 1203 provided in this application can be configured in multiple ways and correspond one-to-one. For example, the traction rope assembly 12 provided in this application includes two traction ropes 1201, and correspondingly, two pulley assemblies 1203 are configured. The two pulley assemblies 1203 are respectively mounted on the first column 1011 and the second column 1012, and can slide and be fixed along the length of the columns on the first column 1011 and the second column 1012, respectively. For example, multiple positioning holes are spaced apart along the length of the first column 1011 and the second column 1012, and locking screws are provided on the pulley assemblies 1203. After sliding the pulley assemblies 1203 on the columns to the required height, the locking screws are inserted into the positioning holes and tightened to fix the pulley assemblies 1203 on the frame 10. For example, when the strength training equipment needs to provide pull-up assistance, the pulley assembly 1203 can be fixed at a higher position (corresponding to the pulley mounting position in the assist working state), so that the traction rope 1201 provides an upward pulling force to the binding member 1202 under the pulling force of the motor, thereby providing upward pull-up assistance to the user. When the strength training equipment needs to provide pull-up resistance, the pulley assembly 1203 can be fixed at a lower position (corresponding to the pulley mounting position in the resistance working state), so that the traction rope 1201 provides a downward pulling force to the binding member 1202 under the pulling force of the motor, thereby providing upward pull-up resistance to the user. This application allows for flexible adjustment of the height position of the pulley assembly 1203 by sliding it up and down on the frame 10, facilitating the use habits of different users, facilitating the switching of the traction rope assembly 12 between different working states, providing a more suitable pull-up training method, and improving training effect.

[0052] In one embodiment, the binding 1202 provided in this application can be detachably connected to the traction rope 1201. For example, the traction rope 1201 and the binding 1202 can be connected by a hook. When pull-up training is not required, the binding 1202 can be removed and the traction rope 1201 can be wound up by a motor until the first end abuts against the pulley block 1203, which is convenient for users to carry out other types of training or store strength training equipment.

[0053] In one embodiment, when the restraint 1202 is attached to the user, if the height of the restraint 1202 is lower than the height of the pulley block 1203, the tension applied by the motor to the traction rope 1201 will be converted into an upward tension on the restraint 1202, providing upward assistance to the user. At this time, the traction rope assembly 12 operates in the assist working state. When the height of the restraint 1202 is higher than the height of the pulley block 1203, the tension applied by the motor to the traction rope 1201 will be converted into a downward tension on the restraint 1202, providing downward resistance to the user. At this time, the traction rope assembly 12 operates in the resistance working state.

[0054] As shown in Figure 3, a schematic diagram of a strength training device in assisted working mode, when the user needs assistance with pull-ups, the pulley assembly 1203 on the first column 1011 and the second column 1012 can be adjusted to a higher position, and the binding 1202 can be attached to the user. Optionally, attaching the binding 1202 to the user in assisted working mode can be done by wearing the binding 1202 on the user's body (Figure 2 shows the binding 1202 in the position of being worn by the user), or by stepping on the binding 1202 under the user's feet (Figure 3 shows the binding 1202 in the position of being stepped on by the user). The user can select the pull-up training assistance mode in the interactive interface provided by the interactive panel 14, and can also select the corresponding training mode according to training needs. After completing the setting of training-related parameters and starting training, the interactive panel 14 will control the motor to provide tension to the traction rope 1201 based on the motor control mode corresponding to the selected training mode. At this time, the direction of force on the traction rope 1201 on the side of the first column 1011 is shown by arrow A1 in the figure, the direction of force on the traction rope 1201 on the side of the second column 1012 is shown by arrow A2 in the figure, and the direction of the resultant force of the traction ropes 1201 on both sides on the binding member 1202 is shown by arrow A3 in the figure. It can be seen that the traction rope 1201 will provide upward assistance during the user's pull-up training.

[0055] As shown in Figure 4, a schematic diagram of a strength training device in resistance mode is provided. When the user needs the strength training device to provide resistance for pull-ups, the pulley assembly 1203 on the first column 1011 and the second column 1012 can be adjusted to a lower position, and the binding 1202 can be attached to the user. Optionally, attaching the binding 1202 to the user in resistance mode can be done by wearing the binding 1202 on the user's body (e.g., binding the binding 1202 around the user's waist). The user can select the resistance mode for pull-up training in the interactive interface provided by the interactive panel 14, and can also select the corresponding training mode according to training needs. After completing the setting of training-related parameters and starting training, the interactive panel 14 will control the motor to provide tension to the traction rope 1201 based on the motor control mode corresponding to the selected training mode. At this time, the direction of force on the traction rope 201 on the side of the first column 1011 is shown by arrow B1 in the figure, the direction of force on the traction rope 1201 on the side of the second column 1012 is shown by arrow B2 in the figure, and the direction of the resultant force of the traction ropes 1201 on both sides on the binding piece 1202 is shown by arrow B3 in the figure. It can be seen that the traction rope 201 will provide downward resistance during the user's pull-up training.

[0056] In one embodiment, a motor housing cavity structure 1014 is formed at the bottom of the frame 10, the motor assembly 13 is disposed in the motor housing cavity structure 1014, the third column 1013 extends upward from the middle of the top of the motor housing cavity structure 1014, and the interactive panel 14 is directly or indirectly mounted on the third column 1013. The height of the interactive panel 14 is higher than the height of the motor housing cavity structure 1014 and lower than the height of the grip portion 15.

[0057] In one embodiment, the vertical plane formed by the first column 1011 and the second column 1012 is closer to the end of the pedal 11 than the plane where the display screen is located.

[0058] In one possible embodiment, the interactive interface of the interactive panel 14 provided in this application can also be used to select the assistance and / or resistance magnitude assessment function, which is used to assess the assistance and / or resistance of pull-ups based on at least one of the configured user weight, bodyweight training volume and target training volume.

[0059] For example, after selecting the assistance and / or resistance assessment function on the interactive interface, the user can configure their weight, bodyweight training volume, and target training volume in the interface. The interactive panel 14 can assess the assistance and / or resistance for pull-ups based on at least one of the parameters: user weight, bodyweight training volume, and target training volume. The assessment of the assistance and / or resistance for pull-ups can refer to the determination of training force using the strength training device control method provided in this application embodiment (i.e., using training force as the assessment assistance and / or resistance), which will not be elaborated upon in this embodiment. This application provides an assistance and / or resistance assessment function through the interactive interface, which can assess the more suitable assistance and / or resistance for pull-ups based on at least one of the configured parameters: user weight, bodyweight training volume, and target training volume, thereby improving the pull-up training effect.

[0060] In other embodiments, the assistance and / or resistance of pull-ups can also be evaluated based on any one of the parameters, or any combination of both, of user weight, bodyweight training volume, and target training volume. This application does not specifically limit the number or combination of parameters used. Those skilled in the art can select appropriate parameters or parameter combinations based on actual needs.

[0061] Optionally, the interactive interface provided in this application can also be used to select artificial intelligence-assisted functions, such as configuring online and / or offline artificial intelligence modules in the interactive panel 14. When the user triggers the artificial intelligence-assisted function through the interactive interface, training assistance information can be provided to the user based on the artificial intelligence-assisted function, and / or the operation of the motor can be controlled based on the interaction information with the user, so as to provide the user with a richer training experience.

[0062] In one possible embodiment, the training modes provided in this application include one or more combinations of standard mode, elastic mode, eccentric mode, isokinetic mode and pull-up mode.

[0063] The standard mode, elastic mode, centrifugal mode, and constant speed mode are existing modes in this field and will not be described in detail here. The motor control mode corresponding to the pull-up mode is that the motor force is negatively correlated with the extension length of the traction rope 1201. That is, in the pull-up mode, the motor output force decreases as the extension length of the traction rope 1201 increases. At this time, in the assist mode, the user needs less force to resist gravity during the pull-up process (the motor output force gradually increases as the traction rope 1201 is retracted), while in the resistance mode, the user needs less force to lift the body during the pull-up process (the motor output force gradually decreases as the traction rope 201 is extended).

[0064] This application provides a selection of training modes through an interactive interface, including one or more combinations of standard mode, elastic mode, eccentric mode, isokinetic mode, and pull-up mode. With the cooperation of different training modes and the working state of the traction rope component 12, a variety of pull-up training modes can be realized, achieving a variety of interesting and multifunctional assisted or resistance training methods, effectively improving the pull-up training effect.

[0065] As described above, the user is provided with a variety of training modes through the interactive interface. The motor control mode corresponding to the training mode selected by the user provides tension to the traction rope 1201. The user can attach the binding piece 1202 to the body and put the traction rope assembly 12 into the assist working state or the resistance working state, and grasp the handle 15 to perform pull-up training. At this time, the tension can be converted into pull-up assistance or resistance by using the assist working state or the resistance working state of the traction rope assembly 12, providing the user with appropriate pull-up assistance or resistance. With the cooperation of different training modes and the working state of the traction rope assembly 12, a variety of pull-up training modes can be realized, thereby improving the pull-up training effect.

[0066] Figure 5 shows a flowchart of a strength training equipment control method provided in an embodiment of this application. The strength training equipment control method provided in this application can be applied to the interactive panel of the strength training equipment provided in any of the above embodiments (e.g., implemented through the main control module in the interactive panel). The strength training equipment control method can be executed by a strength training control device, which can be implemented in hardware and / or software and integrated in the control device.

[0067] The following description uses a strength training control device to execute a strength training equipment control method as an example. Referring to Figure 5, this strength training equipment control method includes:

[0068] S410: Receives parameter setting operation input on the interactive interface, and determines at least one parameter among user weight, bodyweight training quantity, and target training quantity based on the parameter setting operation.

[0069] For example, after detecting a parameter setting operation performed by the user on the interactive interface, at least one parameter among the user's weight, bodyweight training volume, and target training volume can be determined based on the parameter setting operation. The user's weight, bodyweight training volume, and target training volume can be parameters input by the user in real time, previously recorded parameters, or parameters detected by strength training equipment or other detection or training equipment.

[0070] In one embodiment, the bodyweight training count can be understood as the number of pull-ups a user can perform without assistance or resistance, and the target training count can be understood as the number of pull-ups the user expects to complete. When a user needs to use strength training equipment to provide assistance or resistance for pull-ups, they can set parameters on the parameter settings page provided in the interactive interface to set at least one of the following parameters: user weight, bodyweight training count, and target training count.

[0071] S420: Determine the training force based on the working status of the traction rope assembly and at least one of the following parameters: user weight, bodyweight training volume, and target training volume.

[0072] In one embodiment, in addition to displaying a training mode configuration page with selectable training modes, the interactive interface may also display a working state configuration page for selecting the working state. Users can perform working state configuration operations on the working state configuration page to select whether the working state of the traction rope component is an assist working state or a resistance working state.

[0073] For example, the working state of the traction rope assembly is determined according to the working state configuration operation, and the training force (i.e. the tension applied by the motor to the traction rope) provided to the user is determined according to the working state of the traction rope assembly and at least one of the parameters determined above, namely, the user's weight, the number of self-weight training sessions, and the target number of training sessions.

[0074] In other embodiments, the training force is determined based on only one parameter or any combination of two parameters: user weight, bodyweight training volume, and target training volume, in conjunction with the working state of the traction rope assembly. This application does not specifically limit the number or combination of parameters used.

[0075] In one possible embodiment, during assisted operation, if the user's training speed is found to be less than a preset speed and the duration of this speed is greater than a preset duration, the motor is controlled to increase torque output. Here, the user's training speed can be understood as the speed at which the user performs pull-ups (e.g., the speed at which they complete one pull-up).

[0076] For example, in assisted operation mode, the system continuously monitors the user's training speed. If the system detects that the user's training speed is less than a preset speed but the duration exceeds a preset duration, it indicates that the user may lack sufficient strength to perform pull-ups. In this case, the system can control the motor to increase torque output, thereby increasing the assistance provided to the user and helping them complete pull-up training in assisted mode. This application improves the user experience by controlling the motor to increase torque output when the user's training speed is detected to be less than a preset speed but the duration exceeds a preset duration in assisted operation mode.

[0077] In one possible embodiment, under resistance working conditions, if the user's training speed is found to be lower than a preset speed and the duration is greater than a preset duration, the motor is controlled to reduce torque output. For example, if the user's training speed is continuously monitored under resistance working conditions, and it is detected that the user's training speed is lower than a preset speed and the duration is greater than a preset duration, the user may lack sufficient strength to perform pull-ups. In this case, the motor can be controlled to reduce torque output, reducing the resistance force on the user and making it easier for the user to complete pull-up training under resistance conditions. This application assists the user in completing pull-up training under resistance conditions by controlling the motor to reduce torque output when the user's training speed is found to be lower than a preset speed and the duration is greater than a preset duration under resistance working conditions, thereby improving the user experience.

[0078] In one possible embodiment, the motor is controlled to provide tension to the traction rope based on the motor control mode corresponding to the selected training mode and the training force.

[0079] For example, after determining the training force, the motor can be controlled to provide tension to the traction rope according to the motor control mode corresponding to the training mode selected by the user and the training force. The tension provided by the motor to the traction rope can be consistent with the training force, meaning the tension provided by both traction ropes is the training force. Alternatively, the tension provided by the motor to the traction rope can be evenly distributed according to the number of traction ropes; for example, if the tension provided by the motor to the traction rope is half of the training force, then the tension provided by both traction ropes is half of the training force. This embodiment uses the tension provided by the traction ropes as an example for description.

[0080] For example, in standard training mode, the motor control mode controls the motor to output a fixed training force. The user will perform pull-ups with assistance or resistance corresponding to this training force. In elastic training mode, the motor control mode ensures the motor's force is positively correlated with the extension length of the traction rope. The motor's output force increases as the rope extension length increases. Optionally, the maximum output force can be the training force, or the motor's output force can increase with the rope extension length based on the training force. In eccentric training mode, the motor control mode ensures the retraction force is greater than the extension force. For example, when the rope is pulled out, the motor's output force is the training force, and when the rope is retracted, the motor output force is greater than the training force; or, when the rope is pulled out, the motor's output force is less than the training force, and when the rope is retracted, the motor output force is the training force. When the training mode is pull-up mode, the motor control mode is such that the motor force is negatively correlated with the extension length of the traction rope. The motor output force decreases as the extension length of the traction rope increases. Optionally, the motor output force can decrease as the extension length of the traction rope increases based on the training force, or the motor output force can increase as the extension length of the traction rope decreases based on the training force.

[0081] The above describes a system that determines at least one parameter among user weight, bodyweight training repetitions, and target training repetitions based on parameter settings input through the interactive interface. It also determines the training force based on the working state of the traction rope assembly and at least one of these parameters. Furthermore, the system provides the user with a variety of training modes to choose from through the interactive interface. Based on the selected training mode's corresponding motor control mode and training force, the system controls the motor to provide tension to the traction rope. The user can attach the restraints to their body, placing the traction rope assembly in either an assist or resistance mode, and then grip the handles for pull-up training. The traction rope assembly's assist or resistance mode converts the tension into pull-up assistance or resistance, providing the user with appropriate pull-up assistance or resistance. By coordinating different training modes and the working state of the traction rope assembly, a variety of pull-up training modes can be achieved, improving the effectiveness of pull-up training.

[0082] Referring to Figure 6, in one embodiment, the strength training device includes a mounting bracket 16, an interactive panel 14, and a detection module 17. The mounting bracket 16 supports and bears the interactive panel 14. The interactive panel 14 is rotatably mounted on the mounting bracket 16, allowing it to rotate relative to the mounting bracket 16 to a first position and a second position. The detection module 17 detects the position of the interactive panel 14. When the detection module 17 detects that the interactive panel 14 has rotated to the first position, the interactive panel 14 displays a first interface; when the detection module 17 detects that the interactive panel 14 has rotated to the second position, the interactive panel 14 displays a second interface. Thus, simply rotating the interactive panel 14 allows for quick switching between the first and second interfaces, providing convenience and improving operational ease.

[0083] In some embodiments, the detection module 17 can be a position sensor, which is set on the interactive panel 14. Based on the magnitude or change of the parameter value of the position sensor, the position of the interactive panel 14 is determined to be a first position or a second position. Based on the position of the interactive panel 14, a first interface or a second interface is displayed.

[0084] Optionally, the position sensor is a displacement sensor, which can be installed within the interactive panel 14. The displacement sensor can monitor changes in the position of the interactive panel 14, and automatically switch the display interface when the position change exceeds a preset threshold. Specifically, when the interactive panel 14 is in the first position, the display screen shows the first interface. When the interactive panel 14 rotates from the first position to the second position, the displacement sensor detects that the position change of the display screen exceeds the preset threshold, thereby switching to the second interface.

[0085] In other embodiments, the position sensor can be an angle sensor, and the switching of the display interface is achieved by using the changes in the parameters of the angle sensor. The principle is basically the same as that of the displacement sensor, and will not be described in detail here.

[0086] Optionally, the strength training equipment also includes a controller (not shown). The controller can communicate with the detection module 17 via wired or wireless means. The detection module 17 detects the position information of the interactive panel 14 in real time and sends it to the controller. Thus, the controller can control the interactive panel 14 to switch the display interface according to the position information of the interactive panel 14.

[0087] In some embodiments, the detection module 17 includes a first detection element 170 and a second detection element 172. The first detection element 170 is disposed on the mounting bracket 16, and the second detection element 172 is disposed on the back of the interactive panel 14. One of the first detection element 170 and the second detection element 172 is a sensing element, and the other is a triggering element. When the interactive panel 14 is rotated to the first position, the sensing element fails to sense the triggering element, and the interactive panel 14 displays the first interface. When the interactive panel 14 is rotated to the second position, the sensing element can sense the triggering element, and the interactive panel 14 displays the second interface.

[0088] The mounting bracket 16 and the back of the interactive panel 14 are respectively provided with a first detection element 170 and a second detection element 172. The first detection element 170 and the second detection element 172 can be used as sensing elements and triggering elements for each other. When the interactive panel 14 is rotated to the first position (see Figure 7), the distance between the sensing element and the triggering element is far, and the sensing element does not detect the triggering element. At this time, the interactive panel 14 displays the first interface (such as the display interface corresponding to the running training mode). As the interactive panel 14 rotates from the first position to the second position, the distance between the sensing element and the triggering element gradually approaches. When the interactive panel 14 is in the second position (see Figure 8), the distance between the sensing element and the triggering element is close, and the sensing element can detect the triggering element and switch the interactive panel 14 to the second interface (such as the display interface corresponding to the strength training mode).

[0089] In some embodiments, the sensing element is a Hall sensor and the triggering element is a magnetic element, for example, a magnet.

[0090] When the interactive panel 14 is in the first position, the distance between the Hall sensor and the magnetic element is at its greatest. At this time, the Hall sensor cannot detect the magnetic field generated by the magnetic element, and the interactive panel 14 displays the first interface. As the interactive panel 14 rotates from the first position to the second position, the distance between the Hall sensor and the magnetic element gradually decreases, reaching its closest point when the interactive panel 14 is in the second position. At this time, the Hall sensor can detect the magnetic field generated by the magnetic element, causing the Hall sensor to be triggered and output a corresponding sensing signal to the controller, which then controls the interactive panel 14 to switch to the second interface.

[0091] It is understood that in this embodiment, the sensing element and the triggering element are configured as a Hall sensor and a magnetic element, respectively. The switching of the display interface of the interactive panel 14 can be realized through non-contact sensing between the Hall sensor and the magnetic element. No physical contact is required, which can avoid mechanical wear and improve reliability.

[0092] Alternatively, in other embodiments, the sensing element and the triggering element may also be used to switch the display interface of the interactive panel 14 by means of contact sensing. For example, in one embodiment, the sensing element may be a mechanical micro switch and the triggering element may be a metal spring.

[0093] In some embodiments, the first detection element 170 is a sensing element, and the second detection element 172 is a triggering element. That is, a sensing element (such as a Hall sensor) is provided on the mounting bracket 16, and a triggering element (such as a magnet) is provided on the back of the interaction panel 14.

[0094] In this embodiment, by placing the sensing element on the mounting bracket 16, the position of the sensing element remains unchanged during the rotation of the interactive panel 14, making it less likely for signal interference to occur due to the movement or vibration of the interactive panel 14, thereby improving stability and anti-interference during use.

[0095] Referring to Figures 7 and 8, in one embodiment, the strength training equipment further includes a treadmill 20, which includes a running belt 21 disposed on the footplate 11. An interaction panel 14 may be mounted on the third column 1013.

[0096] It is understood that in some embodiments, the mounting bracket 16 can be part of the third column 1013, that is, the first detection element 170 is provided on the third column 1013 of the strength training equipment. In other embodiments, the mounting bracket 16 can be installed on the third column 1013 of the strength training equipment by means of screwing, snap-fitting, welding, etc.

[0097] The strength training equipment has a running training mode and a strength training mode. When the interactive panel 14 is rotated to the first position (landscape mode), the interactive panel 14 displays the first interface corresponding to the running training mode; when the interactive panel 14 is rotated to the second position (portrait mode), the interactive panel 14 displays the second interface corresponding to the strength training mode.

[0098] To switch to running training mode, users simply rotate the interactive panel 14 to the first position, at which point the first interface will be displayed. To switch to strength training mode, users simply rotate the interactive panel 14 to the second position, at which point the second interface will be displayed. The operation is simple and convenient.

[0099] Optionally, the first interface can display running-related data, such as running speed, running time, distance run, calories burned, heart rate monitoring, and remaining time. The second interface can display strength training-related data, such as the name of the currently performed training exercise, the corresponding number of sets and repetitions, the rest time between sets, the weight or resistance level used, and the time required to complete each set.

[0100] Referring to Figure 9, in one embodiment, the strength training device further includes a first arm 32 and a second arm 33, wherein the first arm 32 and the second arm 33 are detachably mounted on the frame 10, and the first arm 32 and the second arm 33 are arranged opposite each other at a distance.

[0101] Specifically, the strength training equipment includes a first arm bar 32, a second arm bar 33, and a training assembly 34. The frame 10 has a first mounting portion 103 and a second mounting portion. The training assembly 34 includes a traction cable assembly 341 and a grip bar 342. The frame 10 is used to mount and support the first arm bar 32 and the second arm bar 33. The first arm bar 32 and the second arm bar 33 together support the grip bar 342. After the user completes bench press training, the two ends of the grip bar 342 can be placed on the first arm bar 32 and the second arm bar 33 respectively.

[0102] The first arm 32 is detachably mounted to the first mounting part 103 of the frame 10, and the second arm 33 is detachably mounted to the second mounting part of the frame 10. The detachable mounting includes installation methods using threaded fasteners such as bolts, clips, and pins. The first arm 32 and the second arm 33 are arranged opposite each other. The first arm 32 and the second arm 33 are spaced apart from left to right, and their installation heights are the same or approximately the same. The two ends of the grip bar 342 can be placed on the first arm 32 and the second arm 33 respectively. The traction rope assembly 341 includes a traction rope 3410, one end of which is connected to the grip bar 342, and the other end of which is used to connect to the motor assembly 13. The user exercises by pushing and pulling the grip bar 342. Before using the strength training equipment, the two ends of the grip bar 342 are placed on the first arm 32 and the second arm 33 respectively. Under the action of the force-applying component, the traction rope 3410 applies a pulling force to the grip bar 342 from top to bottom, causing the grip bar 342 to press downward against the first arm 32 and the second arm 33. When using the strength training equipment, the user can adjust their body position in front of the frame 10 to ensure that the grip bar 342 is at a suitable height and angle, ensuring the standard and effectiveness of the training movements. Adjusting the body position includes adjusting the standing posture, squatting posture, lying posture, etc. This embodiment takes adjusting the lying posture as an example. After adjusting the body position, the user can grip the grip bar 342 to perform strength training such as bench press, without having to adjust the body position while gripping the grip bar 342, reducing the complexity and difficulty of the training. After training, simply hang the grip bar 342 on the first arm bar 32 and the second arm bar 33. There is no need to first remove the counterweight applied to the grip bar 342 and then laboriously move the grip bar 342 away from the training position before getting up, thus avoiding accidental injury caused by improper operation.

[0103] Users can also use the first arm 32 and the second arm 33 as parallel bars for corresponding exercise training, such as arm bending exercises. In addition, the first arm 32 and the second arm 33 are detachably installed on the frame 10, which can be easily assembled and disassembled, reducing the cumbersome assembly and disassembly process. This makes it convenient for users to store and move the strength training equipment, or to adjust the layout of the strength training equipment according to their own training needs.

[0104] In one embodiment, there are multiple first mounting parts 103 and multiple second mounting parts. The multiple first mounting parts 103 are arranged sequentially along a preset direction, and the multiple second mounting parts are also arranged sequentially along a preset direction. The first arm 32 is detachably mounted to any first mounting part 103 to adjust its mounting position on the frame 10, and the second arm 33 is detachably mounted to any second mounting part to adjust its mounting position on the frame 10. By providing multiple first mounting parts 103 and multiple second mounting parts, the mounting height of the first arm 32 and the second arm 33 can be adjusted. Users can adjust the placement height of the grip bar 342 according to different heights and exercise needs, improving the applicability of the strength training equipment.

[0105] As shown in Figures 10 to 12, optionally, both the first arm 32 and the second arm 33 include a connecting seat 3201 and a connecting member 3202 disposed on the connecting seat 3201. A connecting hole 104 is provided at both the first mounting part 103 and the second mounting part. The connecting seat 3201 has a sleeve groove 3203 that fits onto the first mounting part 103 or the second mounting part. The connecting seat 3201 is detachably installed on the first mounting part 103 or the second mounting part by engaging with the connecting hole 104 via the connecting member 3202. During installation, the connecting seat 3201 is first fitted onto the first mounting part 103 or the second mounting part at a suitable height through the sleeve groove 3203. Then, the connecting member 3202 is engaged with the connecting hole 104 to achieve a detachable connection between the connecting seat 3201 and the first mounting part 103 or the second mounting part, making the installation of the connecting seat 3201 more convenient and quick. It is understood that detachable installation can also be achieved by using a threaded connection between the connecting member 3202 and the connecting hole 104.

[0106] Optionally, the frame 10 includes a first column 1011 and a second column 1012. To facilitate the insertion of the connector 3202 into the connector hole 104, the first mounting part 103 is located on the outer side of the first column 1011, and the second mounting part is located on the outer side of the second column 1012. The connector hole 104 on the first mounting part 103 and the connector hole 104 on the second mounting part are arranged opposite to each other, that is, the connector hole 104 on the first mounting part 103 and the connector hole 104 on the second mounting part are both located on the outer side of the frame 10.

[0107] In some embodiments, the connector 3202 has a limiting part 3204 and a connecting part 3205. The limiting part 3204 is connected to the connector 3201 through the connecting part 3205. The connecting part 3205 is engaged in the locking hole of the connector 3201. A clamping gap is formed between the limiting part 3204 and the connector 3201. The connector 3201 is movably sleeved on the first mounting part 103 or the second mounting part to switch between a disassembled position and a locked position. When the connector 3201 is in the disassembled position, the limiting part 3204 can be inserted into or pulled out of the connecting hole 104, realizing the detachable installation of the connector 3201. When the connector 3201 is in the locked position, the first mounting part 103 or the second mounting part is engaged between the limiting part 3204 and the connector 3201, realizing the fixation of the connector 3201, thereby enabling the first arm 32 and the second arm 33 to support the grip 342.

[0108] Furthermore, the frame 10 also has an abutment portion 105, which is provided on the outer side of the first column 1011 and the outer side of the second column 1012 of the frame 10. The connecting seat 3201 is rotatably mounted on the first mounting part 103 or the second mounting part through the cooperation of the connecting member 3202 and the connecting hole 104. The connecting part 3205 of the connecting member 3202 can rotate within the connecting hole 104, so that the connecting seat 3201 can rotate relative to the frame 10. The abutment portion 105 is located on the downward rotation path of the inner wall of the sleeve groove 3203. When the connecting seat 3201 is in the locked position, the inner wall of the sleeve groove 3203 abuts against the abutment portion 105 to prevent the connecting seat 3201 from rotating downward. Both the first arm 32 and the second arm 33 are elongated. When the first arm 32 and the second arm 33 are vertically positioned or tend to be vertically positioned, the connecting seat 3201 is in the disassembly position. When the first arm 32 and the second arm 33 are horizontally positioned or tend to be horizontally positioned, the connecting seat 3201 is in the locking position. At this time, the inner wall of the sleeve groove 3203 abuts downward against the abutment part 105, preventing the first arm 32 and the second arm 33 from continuing to rotate downward, thus achieving the installation limit of the connecting seat 3201 and keeping the first arm 32 and the second arm 33 horizontal. When it is necessary to disassemble the first arm 32 and the second arm 33, they can be quickly disassembled by rotating them upward.

[0109] In one embodiment, both the first arm 32 and the second arm 33 further include a support rod 3207. The support rod 3207 has a first segment 3208 connected in sequence and a second segment 3209 connected to the first segment 3208. The first segment 3208 is rotatably mounted on the connecting seat 3201, and the projections of the first segment 3208 and the second segment 3209 along the rotation axis of the first segment 3208 are at least partially misaligned. That is, the projection of the second segment 3209 along the rotation axis of the first segment 3208 does not completely coincide with the projection of the first segment 3208 along its own rotation axis. Thus, when the support rod 3207 of the first arm 32 and the second arm 33 rotates, the distance between the second segments 3209 of the first arm 32 and the second arm 33 can change. By rotating the support rod 3207, the width of the first arm 32 and the second arm 33 can be adjusted, allowing the strength training equipment to adapt to users of different weights.

[0110] In some embodiments, both the first arm 32 and the second arm 33 further include a locking element 3211. The connecting seat 3201 has a rod groove 3212 and an arcuate groove 3213 extending circumferentially along the rod groove 3212. The extension angle of the arcuate groove 3213 can be 30 degrees, 90 degrees, 180 degrees, 360 degrees, etc., to achieve adjustment of different rotation angles of the support rod 3207. The locking element 3211 can be a threaded fastener such as a bolt, or a locking pin, etc. In this embodiment, the locking element 3211 is a bolt, and the extension angle of the arcuate groove 3213 is 180 degrees, achieving two width states for adjustment to adapt to different training width requirements. One end of the first rod segment 3208 is provided with a locking hole 3216 and is rotatably installed in the rod groove 3212. The locking hole 3216 is a threaded hole. The locking element 3211 passes through the arc groove 3213 and locks into the locking hole 3216 of the first rod segment 3208. At this time, the bolt head abuts against the outer side of the connecting seat to achieve a locking connection. After adjusting the width between the first arm 32 and the second arm 33, the support rod 3207 is locked by the locking element 3211.

[0111] Optionally, the support rod 3207 also has a connecting rod segment 3210. The first rod segment 3208 is connected to the second rod segment 3209 via the connecting rod segment 3210. The first rod segment 3208, the connecting rod segment 3210, and the second rod segment 3209 are smoothly connected in sequence. The first rod segment 3208 and the second rod segment 3209 are parallel to each other, thereby allowing for better adjustment of the distance between the second rod segment 3209 of the first arm 32 and the second rod segment 3209 of the second arm 33.

[0112] In one embodiment, both the first arm 32 and the second arm 33 further include an anti-detachment component 3214. The anti-detachment component 3214 is installed on the second arm segment 3209 via a threaded fastener 3215 to prevent the grip 342 from detaching from the support rod 3207 in the direction away from the connecting seat 3201. The anti-detachment component 3214 can also be installed on the second arm segment 3209 by welding, snap-fitting, or integral molding. When the grip 342 is placed on the first arm 32 and the second arm 33, the anti-detachment component 3214 can block the grip 342, preventing it from detaching from the support rod 3207 in the direction away from the connecting seat 3201, thus avoiding the grip 342 falling and causing a safety hazard.

[0113] Please refer to Figure 9 again. In one embodiment, the strength training equipment also includes a first mounting base 35 and a second mounting base 36, both used for mounting the traction rope connection mechanism 310. The first mounting base 35 and the second mounting base 36 are both slidably mounted on the frame 10 along a predetermined direction. The first mounting base 35 is slidably mounted on the first column 1011, and the second mounting base 36 is slidably mounted on the second column 1012. After the height of the first mounting base 35 and the second mounting base 36 is adjusted, they are locked by a pin structure. The first mounting part 103 is located on the moving path of the first mounting base 35, and the second mounting part is located on the moving path of the second mounting base 36. The first mounting base 35 and the first arm 32 share the first mounting part 103, and the second mounting base 36 and the second arm 33 share the second mounting part. That is to say, after the height adjustment of the first mounting base 35 is completed, it can be fixed to the first mounting part 103, and after the height adjustment of the second mounting base 36 is completed, it can be fixed to the second mounting part. By sharing the first mounting part 103 and the second mounting part, the structure of the frame 10 is greatly simplified, and the first arm 32 and the second arm 33 are directly integrated into the original structure of the frame, which is simple in design. Since the first arm 32 and the second arm 33 can be detachably installed, it will not hinder the sliding adjustment of the first mounting base 35 and the second mounting base 36. For example, the connecting seat 3201 and the connecting piece 3202 can be omitted for both the first boom 32 and the second boom 33. The support rod 3207 of the first boom 32 and the support rod 3207 of the second boom 33 can be detachably installed on the first mounting seat 35 and the second mounting seat 36, respectively, so that the first boom 32 and the second boom 33 can be detachably installed on the first mounting seat 35 and the second mounting seat 36, and their height on the frame can be adjusted by the first mounting seat 35 and the second mounting seat 36.

[0114] In some embodiments, one end of the footrest 11 is located at the bottom of the frame 10, and the first arm 32 and the second arm 33 are both mounted to extend along the other end of the footrest 11. The footrest 11 can be used by the user to stand or lie on, and a recliner can also be installed on the footrest 11 for the user to lie on, making it convenient for the user to use.

[0115] In some embodiments, the strength training equipment also includes a third mounting base 311 and a fourth mounting base 312, both used for mounting the traction rope connection mechanism 310. The third mounting base 311 and the fourth mounting base 312 are respectively located on both sides of the pedal 11. The traction rope 3410 passes through the traction rope connection mechanism 310 and then extends upwards. When the traction rope connection mechanism 310 is mounted on the third mounting base 311 and the fourth mounting base 312, the traction rope 3410 passes through the traction rope connection mechanism 310 and then extends upwards, facilitating connection to the grip bar 342 for training. The first arm bar 32 and the second arm bar 33 are located above the pedal 11, facilitating the suspension of the grip bar 342.

[0116] In some embodiments, the first arm 32 and the second arm 33 are at least partially located above the pedal 11, forming a grip training space above the pedal 11.

[0117] Optionally, the length of both the first arm bar 32 and the second arm bar 33 is not less than 35cm. The length direction of the first arm bar 32 and the second arm bar 33 points towards the end of the pedal, which can meet the needs of users of different heights for bench press, as well as bend over the handrail of the treadmill or for performing arm curl exercises.

[0118] Optionally, the strength training equipment also includes a motor housing structure 1014 and a motor assembly 13 installed within the motor housing structure 1014. The output end of the motor of the motor assembly 13 is connected to the traction rope 3410, and the motor housing structure 1014 is connected to one end of the pedal 11 and to the frame 10, thereby providing tension to the traction rope 3410.

[0119] In one embodiment, referring to Figure 13, the strength training device further includes a treadmill 20. The treadmill 20 has a running belt 21 mounted on the pedals 11. When the strength training device is used for running, the first arm bar 32 and the second arm bar 33 can be used as handrails for the user, improving the safety of the exercise.

[0120] Optionally, there are two traction ropes 3410, which are arranged at intervals and connected to both ends of the grip bar 342 respectively. The first arm bar 32 and the second arm bar 33 are located between the two traction ropes 3410, so that the pulling force of the grip bar 342 is more balanced.

[0121] Please refer to Figure 14, which shows a strength training device with a slow descent mechanism in some embodiments. This strength training device is used to provide users with training in a variety of movements.

[0122] In one embodiment, the strength training device further includes a damping mechanism, one end of the pedal 11 is rotatably connected to the frame 10, the pedal 11 has a folded state and a flattened state, and the damping mechanism is disposed between the pedal 11 and the bottom of the frame 10 to provide a buffering force to prevent the pedal 11 from switching from the folded state to the flattened state.

[0123] Specifically, a motor housing structure 1014 is formed at the bottom of the frame 10. A motor assembly 13 is installed inside the motor housing structure 1014. The motor of the motor assembly 13 is used to provide training resistance. The output end of the motor is connected to a winding wheel, and the motor drives the winding wheel to rotate. The traction rope assembly includes an index rope 452 and a guide rope pulley group 451. The guide rope pulley group 451 is respectively fitted on both sides of the bracket 10. One end of the index rope 52 is connected to the winding wheel, and the other end passes through the guide rope pulley group 451 and is connected to the training component. The training component can be a training handle, a training bar, a training grip, etc., for user training.

[0124] Referring again to Figure 14, pedal 11 is in a flattened state. During training, the user typically steps on pedal 11, and the user's own weight acts on pedal 11, helping to ensure the stability of the entire strength training equipment during training. Alternatively, pedal 11 can be used to place a training bench, on which the user can sit or lie for training.

[0125] Please refer to Figures 14 and 15. The pedal 11 is rotatably connected to the motor housing structure 1014. The pedal 11 includes a pedal body 112 and two support arms 113. The two support arms 113 are spaced apart at one end of the pedal body 112 facing the motor housing structure 1014. The two support arms 113 are located on the sides of the motor housing structure 1014 and are rotatably connected to it. A damping mechanism is provided between the pedal 11 and the motor housing structure 1014.

[0126] The two support arms 113 may be integrally formed with the pedal body 112 or fixedly connected to the pedal body 112. This application does not make specific limitations on this.

[0127] In some embodiments, the support arm 113 is generally strip-shaped and extends to the side of the motor housing structure 1014 to facilitate the rotational connection between the pedal 11 and the motor housing structure 1014. The specific shape of the support arm 113 is not specifically limited in this application.

[0128] The pedal 11 has a folded state (as shown in Figure 15) and a flattened state (as shown in Figure 14). When training is needed, the pedal 11 is unfolded to the flattened state; when the user finishes training, the pedal 11 is folded to the folded state for easy storage of the strength training equipment. It should be noted that the process between the flattened and folded states is the unfolding process of the pedal 11.

[0129] To ensure the safe and effortless unfolding of the pedal 11 and guarantee the safety of the strength training equipment, the strength training equipment of this application includes a slow-descent mechanism. Specifically, a damping mechanism is disposed between the pedal 11 and the motor housing structure 1014 to provide a buffering force that prevents the pedal 11 from switching from a folded state to a flattened state. When the pedal 11 unfolds from a folded state to a flattened state, the buffering force provided by the damping mechanism facilitates the slow descent of the pedal 11; and when the pedal 11 folds from a flattened state to a folded state, the buffering force provided by the damping mechanism assists in folding the pedal 11. With the motor housing structure 1014 remaining relatively stationary, the damping mechanism applies resistance to the pedal 11 when the pedal 11 rotates relative to the motor housing structure 1014.

[0130] The type of damping mechanism and its installation location are not specifically limited. The damping mechanism can be a rotary damper, friction damper, hydraulic damper, liquid-gas mixture damper, electromagnetic damper, mechanical damper, or other types of dampers. The damping mechanism can be installed on the side of the motor housing structure 1014, or, when the pedal 11 is in a flattened state, at the end of the motor housing structure 1014 facing the pedal 11.

[0131] In some embodiments, a damping mechanism is disposed between the support arm 113 and the side of the motor housing structure 1014. In this case, during the unfolding or retracting of the pedal 11, the resistance provided by the damping mechanism acts on the support arm 113 and then on the pedal body 112.

[0132] The damping mechanism can be installed on the support arm 113. When the support arm 113 rotates relative to the side of the motor housing structure 1014, the angular displacement of the support arm 113 corresponds to the stroke of the damping mechanism providing the damping force. The damping mechanism can be installed at the pivot point of the support arm 113 or on the rod of the support arm 113.

[0133] In some embodiments, the rotatable connection between the support arm 113 and the motor housing structure 1014 has a pivot structure, and the damping mechanism is a rotary damper, which is mounted on the pivot structure. Specifically, the rotary damper is mounted on a rotating shaft, the rotating part of the rotary damper is fixedly connected to the support arm 113, and the fixed part of the rotary damper is fixedly connected to the motor housing structure 1014.

[0134] In one embodiment, the motor housing cavity structure 1014 has a vertical docking portion 1015, which is positioned opposite to the pedal body 112 when the pedal 11 is in a flattened state.

[0135] The damping mechanism can be located between the bottom of the pedal body 112 and the vertical docking part 1015.

[0136] It should be explained that when the pedal 11 is in a flattened state, the pedal body 112 is connected to the motor housing structure 1014. To ensure a smooth connection, this application provides a vertical connecting portion 1015 at the end of the motor housing structure 1014 facing the pedal 11. The height of the vertical connecting portion 1015 is approximately the same as the thickness of the pedal body 112. Furthermore, the term "connecting" in the vertical connecting portion 1015 only represents a physical positional relationship, indicating that the vertical connecting portion 1015 of the motor housing structure 1014 and the pedal body 112 are positioned opposite each other, without implying a necessary connection between them.

[0137] Optionally, the damping mechanism is a telescopic rod-shaped damper. A first mounting portion 1016 is provided on the vertical connecting portion 1015, and a second mounting portion 1121 is provided on the bottom of the pedal body 112. One end of the telescopic rod-shaped damper is rotatably mounted on the first mounting portion 1016, and the other end is rotatably mounted on the second mounting portion 1121. In some embodiments, the telescopic rod-shaped damper can be a pneumatic damping rod 460, a hydraulic damping rod, or a gas-liquid hybrid damping rod. Specifically, rotational mounting can be achieved using a pin.

[0138] Please refer to Figure 16. Taking the pneumatic damping rod 460 as an example, the pneumatic damping rod 460 has a locked state and an operating state. An operating switch 461 is provided on the pneumatic damping rod 460. By operating the operating switch 461, the pneumatic damping rod 460 can be unlocked, thereby putting the pneumatic damping rod 460 into the operating state to assist the cushioned descent of the pedal 11. After the pedal 11 is folded, the pneumatic damping rod 460 extends to the corresponding stroke, and the operating switch 461 can automatically lock.

[0139] In some embodiments, when the pedal 11 is in the flattened state, the telescopic rod-shaped damper is in the compressed state, and the height of the first mounting part 1016 is not higher than the height of the second mounting part 1121. Typically, a locking mounting mechanism 470 is provided between the pedal 11 and the motor housing structure 1014. When the pedal 11 is in the flattened state for user training, the locking mounting mechanism 470 is generally used to lock the pedal 11 and the motor housing structure 1014, ensuring the stability of the device during training. When the user finishes training and is ready to fold the pedal 11, the user first unlocks the locking mounting mechanism 470 and then raises the pedal 11. At this time, since the height of the first mounting part 1016 is not higher than the height of the second mounting part 1121, the telescopic rod-shaped damper can promptly provide an upward force to the pedal 11, thereby saving the force required for the user to fold the pedal 11.

[0140] In some embodiments, a decorative panel is provided at the bottom of the pedal body 112, and an open receiving groove is formed on the decorative panel, which communicates with the second mounting part 1121. The open receiving groove is used to accommodate the telescopic rod-shaped damper. When the pedal 11 is in the flattened state, the telescopic rod-shaped damper is hidden in the open receiving groove, making it convenient for the pedal 11 to be laid flat on the training ground. Optionally, a plurality of ribs are provided at the bottom of the pedal body 112 along the width direction of the pedal body 112, and the second mounting part 1121 is fixedly mounted on the ribs to ensure installation strength. The ribs near the end of the support arm 113 are correspondingly provided with notches to accommodate the telescopic rod-shaped damper.

[0141] Optionally, the telescopic rod damper has an operating switch 461. When the pedal 11 is in a fully folded state, the telescopic rod damper extends to the trigger locking limit stroke, and the operating switch 461 switches to the locked state.

[0142] The telescopic rod damper has an operating switch 461. The user can unlock the telescopic rod damper by operating switch 461, allowing it to compress and provide resistance. When the pedal 11 is fully folded, the corresponding extension length of the telescopic rod damper is the locking limit stroke. At this time, the operating switch 461 is triggered to the locking state. Without unlocking, the telescopic rod damper cannot be compressed, thus effectively limiting the pedal 11 to the fully folded state and ensuring safety and stability in this folded state. Simultaneously, the telescopic rod damper is essentially in its longest extended state, corresponding to its minimum or non-load-bearing state, which helps extend the service life of the telescopic rod damper.

[0143] In some embodiments, the two ends of the vertical docking portion 1015 are respectively provided with locking mounting mechanisms 470 facing the pedal body 112. When the pedal 11 is in a flattened state, the locking mounting mechanisms 470 press against the pedal body 112 to lock the pedal 11, ensuring the stability of the strength training equipment during training. The locking mounting mechanism 470 is also provided with an auxiliary pulley 480, which is used to assist the movement of the strength training equipment in an inclined state.

[0144] Please refer to Figures 1 and 17. One embodiment of the strength training device 100 provided in this application includes: a frame 10, a traction rope assembly 12, a motor assembly 13, an interactive panel 14, and a controller 15.

[0145] The frame 10 includes a motor compartment 1014, within which a motor assembly 13 is installed and connected to a traction rope assembly 12. The motor assembly 13 drives the movement of the traction rope assembly 12. The motor assembly 13 can be equipped with various sensors to collect operating data from the motor. For example, the motor assembly 13 includes an encoder and a current sensor. The encoder records the rotational position of the motor rotor in real time to calculate resistance or the speed or acceleration of the traction rope. The current sensor collects the operating current of the motor to monitor the motor's load and resistance output status.

[0146] Please refer to Figure 18. The traction rope assembly 12 includes a winding reel 121 and a traction rope 122. The output shaft of the motor in the motor assembly 13 is connected to the winding reel 121. The winding reel 121 has a groove, and all the traction ropes 122 are wound in the same groove. The first end of the traction rope 122 is used for the user to apply tension, and the portion of the traction rope 122 away from the first end is wound in the groove of the winding reel 121. The motor in the motor assembly 13 drives the winding reel 121 to rotate, carrying the traction rope 122.

[0147] The interactive panel 14 provides an interactive interface, allowing users to input or select training or fitness exercise types, thereby receiving the user's input or selection of training or fitness exercise types. The interactive panel 14 can also receive user control commands or operations, such as commands or operations to select training exercise types. The interactive panel 14 can also be used to display relevant training information, such as user identity data, real-time training data, or historical training data. The interactive panel 14 can be any suitable type of display screen, such as a touchscreen, display screen, or LCD screen.

[0148] The strength training equipment includes a controller 15, which can store and analyze training data. The controller 15 analyzes the training data based on a preset training model, which includes, for example, training movement types, trainee physiological parameters, training data, and training plans. The preset training model compares and calculates the training data, stores the results (including matching and discrepancy items) locally on the controller 15, and simultaneously uploads the training data or analysis results to a server. The results are then fed back to the user through an interactive panel 14, informing the user of their training progress.

[0149] The controller 15 is also used to monitor in real time whether the strength training equipment 100 has stalled, and when a stall occurs, it triggers a stall protection process. That is, based on the training action type selected by the user, it determines the stall monitoring mode corresponding to the training action type, and controls the strength training equipment 100 to perform a stall protection operation according to the determined stall monitoring mode. For example, it controls the motor in the motor assembly 13 to stop working and retracts the traction rope 122.

[0150] When exercising, the user first sets the type of training exercise or selects a training course on the interactive panel 14. Then, the user stands on the frame 10 and pulls the traction rope 122 with both hands. The strength training device 100 controls the operation of the motor in the motor assembly 13 according to the resistance corresponding to the type of training exercise. Under the control of the motor in the motor assembly 13, the winding wheel 121 pulls the traction rope 122 to generate resistance, allowing the user to complete the training under the action of resistance.

[0151] It should be understood that Figures 1, 17 and 18 are merely schematic illustrations of the strength training device 100 provided in some embodiments of this application, and do not limit the structure or type of the strength training device in other embodiments. The strength training device may include more or fewer components than the strength training device 100 shown in Figure 1, or have a different configuration than the strength training device 100 shown in Figure 1.

[0152] It is understood that the stall protection method based on strength training equipment provided in this application is not only applicable to the strength training equipment provided in the above embodiments, but also applicable to other types of strength training equipment. This application does not limit it in any way.

[0153] The following embodiment of this application provides a stall protection method based on a strength training device.

[0154] Please refer to Figure 19, which shows a flowchart of a stall protection method based on a strength training device provided in some embodiments of this application.

[0155] As shown in Figure 19, the stall protection method based on strength training equipment includes, but is not limited to, the following steps S510-S530:

[0156] S510: Determine the type of target movement the user is training on the strength training equipment.

[0157] Specifically, the interactive interface of the strength training equipment has preset options for various movement types. When the user selects a specific movement type through the input method provided by the interactive interface (such as touch screen, button selection, or voice command), the interactive interface receives the user's movement selection operation, and the strength training equipment determines the target movement type for the user to train on the strength training equipment based on the movement selection operation.

[0158] For example, in some embodiments, if the user selects "pull training" on the interactive interface, the strength training device will determine that the target movement type for the user's training is "pull training".

[0159] In other embodiments, a camera or sensor may be used to identify the user's training movements, or the user's selected course content may be analyzed to determine the training movements, or the user's movement selection before training may be used to determine the target movement type for the user to train on the strength training equipment.

[0160] S520: Determine the target stall monitoring mode corresponding to the target action type.

[0161] In some embodiments, a target stall monitoring mode corresponding to the target action type is determined, which includes, but is not limited to, the following steps S521-S522:

[0162] S521: Determine the target hazard level corresponding to the target action type.

[0163] In this step, a risk assessment is conducted on all movement types beforehand. Based on the characteristics of each movement type and its impact on the user's body, each movement type is categorized into different risk levels (e.g., low, medium, high). After determining the target movement type for the user's training on the strength training equipment, the target risk level corresponding to that target movement type can be determined. For example, in some embodiments, a movement type involving a large muscle group load, such as the "bent-over row," is set at a medium risk level. If the user's target movement type is the bent-over row, the corresponding target risk level is medium. A relatively safe movement type, such as "pull training," is set at a low risk level. If the user's target movement type is pull training, the corresponding target risk level is low. Movement types involving multiple muscle groups, such as "bench press" and "squat," are set at a high risk level. If the user's target movement type is the bench press or squat, the corresponding target risk level is high.

[0164] It is understood that other types of movements and risk levels may also be included. In some embodiments, the risk level for each type of movement may also vary due to changes in environmental factors. For example, the risk level for some types of movements may be increased in low ambient temperatures because low temperatures increase the risk of muscle strain.

[0165] S522: Determine the target stall monitoring mode corresponding to the target hazard level.

[0166] In this step, corresponding stall monitoring modes are pre-set according to different hazard levels to ensure a rapid response to protect user safety in the event of a stall. First, a corresponding stall monitoring mode is set for each hazard level (e.g., low, medium, high). These different monitoring modes include varying requirements for the motor rotation frequency, stall trigger sensitivity, response speed, and response execution measures in the strength training equipment.

[0167] For example, for low-risk levels, a low-risk stall monitoring mode is used. The rotation frequency of the motor in the strength training equipment is within the first preset frequency range (e.g., 5000-6000 rpm / min). The low-risk stall monitoring mode is set to low sensitivity, allowing for a larger range of tension (e.g., resistance magnitude, speed, etc.) fluctuations and a slower response speed. Measures such as reducing resistance output and providing voice guidance to the user to adjust their movements are taken to assist the user in completing the action.

[0168] For medium-risk levels, a medium-risk stall monitoring mode is adopted. The rotation frequency of the motor in the strength training equipment is within the second preset frequency range (e.g., 6000-7000 rpm / min). The medium-risk stall monitoring mode is set to medium sensitivity, allowing a certain range of tension fluctuations, and has a medium-fast response speed. It stops the resistance output, prompts the user to trigger the stall protection operation via voice, and executes the stall protection operation response measures.

[0169] For high-risk levels, a high-risk stall monitoring mode is used. The rotation frequency of the motor in the strength training equipment is within the third preset frequency range (e.g., rotation frequency > 7000 rpm / min). The high-risk stall monitoring mode is set to the highest sensitivity, allowing the smallest tension fluctuation range and the highest level of response speed. When a slight abnormality is detected, stall protection is immediately triggered to ensure the personal safety of the user. The response measures are as follows: stop the resistance output, provide a voice prompt to the user to trigger the stall protection operation, and remind the user in a pop-up window on the interactive interface. After the user confirms the operation, the stall protection operation is executed.

[0170] It should be noted that the classification or distinction of target hazard levels is not limited to the specific content of the above embodiments. Those skilled in the art can make adaptive classifications or distinctions by combining other parameters, indicators or experience.

[0171] Specifically, after determining the target hazard level corresponding to the target action type, the target stall monitoring mode corresponding to the target hazard level can be determined. For example, if the target hazard level is medium, then the target stall monitoring mode is the medium-risk stall monitoring mode.

[0172] S530: Controls the strength training equipment to perform stall protection operations based on the target stall monitoring mode.

[0173] In this step, after a stall occurs and the target stall monitoring mode is determined, the system responds according to the preset target stall monitoring mode and executes the corresponding stall protection operation based on the response measures set for different target stall monitoring modes.

[0174] In some embodiments, if the target stall monitoring mode is a low-risk stall monitoring mode, the drag output is reduced and a prompt voice is issued to guide the user to adjust their actions and assist the user in completing the actions.

[0175] In some embodiments, if the target stall monitoring mode is the medium stall monitoring mode, the drag output is stopped, a voice prompt is given to the user to trigger the stall protection operation, and the stall protection operation is performed, such as performing the rope reeling operation.

[0176] In some embodiments, if the target stall monitoring mode is a high-risk stall monitoring mode, the drag output is stopped, a voice prompt is issued to the user to trigger the stall protection operation, and a pop-up reminder is displayed on the interactive interface. After the user confirms the operation, the stall protection operation is then performed, such as the rope reeling operation.

[0177] This application embodiment determines the stall monitoring mode corresponding to the user's fitness movement type, and then controls the strength training equipment to perform stall protection operation according to the stall monitoring mode. In this way, the occurrence of the rope being retracted immediately after the stall protection is triggered can be reduced, reducing user panic and incorrect operation, reducing the risk of personal injury to the user, and providing safe training protection for the user.

[0178] In other embodiments, the target hazard level can also be determined based on the target training course selected by the user, such as analyzing the training action types in the target course and then determining the target hazard level corresponding to the training action. If the target training course contains multiple training action types, the target hazard level can be determined separately for each different training action type.

[0179] Alternatively, in other embodiments, the target danger level can be determined by actually identifying or detecting the user's specific training actions, such as combining information collected by cameras or sensors to determine the user's training actions, and further combining the training actions to determine the target danger level.

[0180] It should be noted that this application does not specify how to determine the target hazard level during the training process.

[0181] In some embodiments, the target movement type for the user to train on the strength training equipment is determined, including but not limited to the following step S511:

[0182] S511: Responds to the action selection operation received by the interaction interface of the strength training device and determines the type of target action that the user is training on the strength training device.

[0183] In this step, various exercise types are preset on the interface of the strength training equipment, such as push-pull, bench press, squat, rope curl, resistance training, bent-over row, etc. These exercise type options can be displayed to the user in any suitable form, such as buttons, menus, or icons.

[0184] Specifically, when a user selects a specific exercise type through an input method provided by the interactive interface (such as a touchscreen, button selection, or voice command), the interactive interface receives the user's exercise selection. The strength training device responds to the exercise selection, parses the selection, and determines the target exercise type for the user's training on the device. For example, if a user selects the long bar bench press exercise type on the interactive interface, the interface receives the long bar bench press exercise type and determines that the long bar bench press is the target exercise type for the user's training on the strength training device.

[0185] For example, in some embodiments, if the user triggers an action selection operation on the interactive interface as "grip bent-over fly", then the strength training device determines that the target action type for the user to train on the strength training device is "grip bent-over fly".

[0186] In some embodiments, the target movement type for the user to train on the strength training equipment is determined, including but not limited to the following step S512:

[0187] S512: Identify or detect the user's training movements and determine the type of target movement the user is training on the strength training equipment.

[0188] In this step, the strength training equipment is equipped with various sensors, such as lidar, cameras, or infrared sensors. The strength training equipment can identify or detect the user's training movements through the sensors, and determine the type of target movement that the user is training on the strength training equipment based on the user's training movements.

[0189] For example, in some embodiments, if the strength training device recognizes or detects that the user's training action is "long bar supine triceps extension", then the target action type of the user training on the strength training device is determined to be "long bar supine triceps extension".

[0190] In some embodiments, the target movement type for the user to train on the strength training equipment is determined, including but not limited to the following step S513:

[0191] S513: Responds to the training course selection operation received by the interactive interface of the strength training equipment, and determines the target movement type of the user's training on the strength training equipment based on the training content of the training course.

[0192] In this step, the strength training equipment's interactive interface has preset training course options. When a user selects a training course through the input method provided by the interactive interface (such as touchscreen, button selection, or voice command), the interface receives the user's selection. The strength training equipment responds to this selection, obtains the target training course corresponding to the selection, and analyzes the training content within the target course. This content includes the type of training movement, training time, etc., thereby determining the target movement type the user will be training on the strength training equipment. Understandably, if the target training course contains multiple movement types, the corresponding target movement type can be determined separately for each movement type.

[0193] In some embodiments, a target stall monitoring mode corresponding to the target danger level is determined, which includes, but is not limited to, the following step S5221:

[0194] S5221: When the response target hazard level is high-risk, determine the high-risk stall monitoring mode corresponding to the high-risk level as the target stall monitoring mode.

[0195] In this embodiment of the application, the target hazard level includes a high-risk level and a low-risk level, and the target stall monitoring mode includes a high-risk stall monitoring mode and a low-risk stall monitoring mode, wherein the high-risk level corresponds to the high-risk stall monitoring mode, and the low-risk level corresponds to the low-risk stall monitoring mode.

[0196] In this step, if the target hazard level corresponding to the target action type is high-risk, then in response to the target hazard level being high-risk, the high-risk stall monitoring mode corresponding to the high-risk level is determined as the target stall monitoring mode.

[0197] In some embodiments, a target stall monitoring mode corresponding to the target danger level is determined, which includes, but is not limited to, the following step S5222:

[0198] S5222: If the target hazard level is low, determine the low-risk stall monitoring mode corresponding to the low-risk level as the target stall monitoring mode.

[0199] In this step, if the target hazard level corresponding to the target action type is low-risk, then in response to the target hazard level being low-risk, the low-risk stall monitoring mode corresponding to the low-risk level is determined as the target stall monitoring mode.

[0200] In some embodiments, the strength training equipment is controlled to perform stall protection operations based on the target stall monitoring mode, including but not limited to the following steps S531-S534:

[0201] S531: Obtain the rope take-up speed or rope take-up acceleration of the strength training equipment.

[0202] S532: Determine the target stall level based on the rope take-up speed or rope take-up acceleration.

[0203] S533: Determine the stall monitoring sub-mode corresponding to the target stall level as the target stall monitoring sub-mode.

[0204] S534: Control the force training equipment to perform stall protection operation based on the target stall monitoring sub-mode.

[0205] In some embodiments, the target stall monitoring mode includes multiple stall monitoring sub-modes, each stall monitoring sub-mode corresponding to a stall level.

[0206] In this embodiment of the application, after detecting a stall in the strength training equipment, a corresponding target stall monitoring sub-mode is determined based on the rope take-up speed or rope take-up acceleration of the strength training equipment, so as to control the strength training equipment to perform a stall protection operation based on the target stall monitoring sub-mode.

[0207] In step S531, the strength training equipment monitors its rope-retrieval speed and acceleration in real time using speed sensors (e.g., photoelectric sensors or contact sensors), accelerometers, or other monitoring devices, equipment, or components (e.g., encoders, tension sensors), thereby obtaining the rope-retrieval speed and acceleration of the strength training equipment. Here, rope-retrieval speed refers to the speed at which the strength training equipment retracts the traction rope after it has been pulled out, and rope-retrieval acceleration refers to the acceleration at which the strength training equipment retracts the traction rope after it has been pulled out.

[0208] In step S532, different rope retraction speed thresholds and rope retraction acceleration thresholds are set in advance according to the design parameters of the strength training equipment and the user's safety requirements, so as to classify different stall levels and obtain several stall levels that include different rope retraction speed ranges and rope retraction acceleration ranges.

[0209] In some embodiments, three types of stall levels are included: low stall level, medium stall level, and high stall level. Specifically, the rope retrieval speed range and rope retrieval acceleration range for the low stall level are set to less than 1 m / s² and less than 0.5 m / s², respectively. 2 The rope retrieval speed range and retrieval acceleration range for the medium stall level are set to be between 1 m / s and 2 m / s and 0.5 m / s, respectively. 2 -1m / s 2 The retrieval speed range and retrieval acceleration range for the high stall level are set to be greater than 2 m / s² and greater than 1 m / s², respectively. 2 .

[0210] In some embodiments, the rope take-up speed of the strength training device is compared with a preset rope take-up speed threshold to determine the target stall level corresponding to the rope take-up speed. If the rope take-up speed is within the low stall level range, then the low stall level is determined as the target stall level. If the rope take-up speed is within the medium stall level range, then the medium stall level is determined as the target stall level. If the rope take-up speed is within the high stall level range, then the high stall level is determined as the target stall level. For example, if the rope take-up speed of the strength training device is 1.25 m / s, and this rope take-up speed is within the medium stall level range, then the medium stall level is determined as the target stall level.

[0211] In some embodiments, the rope-reclining acceleration of the strength training device is compared with a preset rope-reclining acceleration threshold to determine the target stall level corresponding to the rope-reclining acceleration. If the rope-reclining acceleration is within the low stall level rope-reclining acceleration range, the low stall level is determined as the target stall level. If the rope-reclining acceleration is within the medium stall level rope-reclining acceleration range, the medium stall level is determined as the target stall level. If the rope-reclining acceleration is within the high stall level rope-reclining acceleration range, the high stall level is determined as the target stall level. For example, if the rope-reclining acceleration of the strength training device is 1.1 m / s²... 2 The rope-reeling acceleration is 1.1 m / s². 2 If the rope retrieval acceleration is within the range of high stall level, then the high stall level is determined as the target stall level.

[0212] In step S533, the correspondence between different stall levels (e.g., low stall level, medium stall level, high stall level) and stall monitoring sub-modes is defined in advance in the strength training equipment system. Specifically, low stall level corresponds to low stall monitoring sub-mode, medium stall level corresponds to medium stall monitoring sub-mode, and high stall level corresponds to high stall monitoring sub-mode.

[0213] In some embodiments, a target stall level is identified in the correspondence between stall levels and stall monitoring sub-modes, and the stall monitoring sub-mode corresponding to the target stall level is determined as the target stall monitoring sub-mode. For example, if the target stall level is a medium stall level, then the medium stall monitoring sub-mode corresponding to the medium stall level is determined as the target stall monitoring sub-mode.

[0214] In step S534, after a stall occurs and the target stall monitoring sub-mode is determined, a response is made according to the preset target stall monitoring sub-mode, and the response execution measures set according to different target stall monitoring sub-modes are specifically controlled to perform the corresponding stall protection operation on the strength training equipment.

[0215] In some embodiments, if the target stall monitoring sub-mode is a mild stall monitoring mode, the drag output is reduced and a prompt voice is issued to guide the user to adjust their actions and assist the user in completing the action.

[0216] In some embodiments, if the target stall monitoring sub-mode is the moderate stall monitoring mode, the drag output is stopped, a voice prompt is issued to the user to trigger the stall protection operation, and the stall protection operation is performed, such as performing a rope reeling operation.

[0217] In some embodiments, if the target stall monitoring sub-mode is the severe stall monitoring mode, the drag output is stopped, a voice prompt is issued to the user to trigger the stall protection operation, a pop-up reminder is displayed on the interactive interface, and the stall protection operation, such as the rope reeling operation, is executed after the user confirms the operation.

[0218] For example, in some embodiments, the target stall level is determined based on the rope take-up speed or rope take-up acceleration, specifically including but not limited to the following steps S5321-S5322:

[0219] S5321: Determine the stall detection range corresponding to the rope take-up speed or rope take-up acceleration as the target stall detection range.

[0220] S5322: Determine the stall level corresponding to the target stall detection range as the target stall level.

[0221] In step S5321, the strength training equipment is pre-configured with multiple stall detection ranges, and corresponding stall levels are pre-set according to the stall detection ranges. Each stall detection range corresponds to a stall level.

[0222] In some embodiments, the strength training device is configured with multiple stall detection ranges of less than 1 m / s, greater than 2 m / s, and between 1 m / s and 2 m / s. The stall level corresponding to less than 1 m / s is a low stall level, the stall level corresponding to greater than 2 m / s is a high stall level, and the stall level corresponding to between 1 m / s and 2 m / s is a medium stall level.

[0223] In some embodiments, the rope take-up speed of the strength training device is compared with a set stall detection range to determine the target stall detection range in which the rope take-up speed falls. For example, if the rope take-up speed is 0.5 m / s, it is determined that the rope take-up speed of 0.5 m / s falls within the stall detection range of less than 1 m / s, and the stall detection range of less than 1 m / s is determined to be the target stall detection range. If the rope take-up speed is 2.5 m / s, it is determined that the rope take-up speed of 2.5 m / s falls within the stall detection range of greater than 2 m / s, and the stall detection range of greater than 2 m / s is determined to be the target stall detection range. If the rope take-up speed is 1.3 m / s, it is determined that the rope take-up speed of 1.3 m / s falls within the stall detection range between 1 m / s and 2 m / s, and the stall detection range between 1 m / s and 2 m / s is determined to be the target stall detection range.

[0224] In some embodiments, the strength training device is configured with multiple stall detection ranges less than 0.5 m / s. 2 greater than 1m / s 2 and located at 0.5m / s 2 -1m / s 2 Between, less than 0.5 m / s 2 The corresponding stall level is low stall, greater than 1 m / s. 2 The corresponding stall level is high stall, located at 0.5 m / s². 2 -1m / s 2 The corresponding stall level is the medium stall level.

[0225] In some embodiments, the rope-reclining acceleration of the strength training device is compared with a set stall detection range to determine the target stall detection range in which the rope-reclining acceleration falls. For example, if the rope-reclining acceleration is 0.3 m / s² 2 Therefore, the rope-reeling acceleration is determined to be 0.3 m / s². 2 Located at less than 0.5 m / s 2 If the stall detection range is within the range, then it is determined to be less than 0.5 m / s. 2 The stall detection range is the target stall detection range. If the rope retraction acceleration is 1.2 m / s², then... 2 Therefore, the acceleration of the rope being pulled in is determined to be 1.2 m / s². 2 Located at greater than 1m / s 2 If the stall detection range is within the range, then it is determined to be greater than 1 m / s. 2 The stall detection range is the target stall detection range. If the rope retrieval acceleration is 0.8 m / s², then... 2 Therefore, the rope-reeling acceleration is determined to be 0.8 m / s². 2 Located at 0.5m / s 2 -1m / s 2 Within the stall detection range, 0.5 m / s is determined.2 -1m / s 2 The stall detection range between these ranges is the target stall detection range.

[0226] Understandably, the stall detection range corresponds to the rope take-up speed or rope take-up acceleration of the strength training equipment. When it is determined that the stall detection ranges corresponding to the rope take-up speed and rope take-up acceleration are different, the higher-level stall detection range is selected as the target stall detection range. For example, if it is determined that the stall detection range corresponding to the rope take-up speed is a slight stall range and the stall detection range corresponding to the rope take-up acceleration is a moderate stall range, then the higher-level moderate stall range is selected as the target stall detection range.

[0227] In step S5322, based on the correspondence between stall detection range and stall level, the target stall detection range is found from the correspondence, and the stall level corresponding to the target stall detection range is determined as the target stall level. For example, if the target stall detection range is greater than 2 m / s, then the high stall level corresponding to the target stall detection range greater than 2 m / s is determined as the target stall level. If the target stall detection range is less than 1 m / s, then the low stall level corresponding to the target stall detection range less than 1 m / s is determined as the target stall level. If the target stall detection range is between 1 m / s and 2 m / s, then the medium stall level corresponding to the target stall detection range between 1 m / s and 2 m / s is determined as the target stall level. If the target stall detection range is greater than 1 m / s... 2 Then it is determined to be greater than 1m / s 2 The target stall level is defined as the highest stall level corresponding to the target stall detection range. If the target stall detection range is less than 0.5 m / s², then the target stall level is defined as follows: 2 Therefore, it is determined to be less than 0.5 m / s. 2 The target stall level is defined as the low stall level corresponding to the target stall detection range. If the target stall detection range is located at 0.5 m / s... 2 -1m / s 2 If it falls within this range, then it is determined to be located at 0.5 m / s. 2 -1m / s 2 The intermediate stall level corresponding to the target stall detection range is the target stall level.

[0228] For example, in some embodiments, the stall level corresponding to the target stall detection range is determined as the target stall level, specifically including but not limited to the following step S5324:

[0229] S5324: In response to a rope take-up speed or rope take-up acceleration within a slight stall range, determine the slight stall level corresponding to the slight stall range as the target stall level.

[0230] In this step, the pre-configured stall detection ranges include a slight stall range, a moderate stall range, and a severe stall range, and a correspondence between the stall detection range and the stall level is set according to the stall detection range. Specifically, each stall detection range corresponds to a stall level, that is, the slight stall range corresponds to the slight stall level, the moderate stall range corresponds to the moderate stall level, and the severe stall range corresponds to the severe stall level.

[0231] In some embodiments, if it is determined that the rope take-up speed or rope take-up acceleration of the strength training device is within the minor stall range, then the minor stall range is found in the correspondence between stall detection range and stall level, and the minor stall level corresponding to the minor stall range is determined as the target stall level.

[0232] For example, if the slight stall range is less than 1 m / s or less than 0.5 m / s 2 The rope-reeling speed of the strength training equipment is 0.6 m / s or the rope-reeling acceleration is 0.25 m / s². 2 If the rope retrieval speed is 0.6 m / s, it falls within the slight stall range of less than 1 m / s, or the rope retrieval acceleration is 0.25 m / s². 2 At less than 0.5 m / s 2 For minor stalls, the range is determined by the correspondence between stall detection range and stall level, specifying a speed less than 1 m / s or less than 0.5 m / s. 2 The minor stall level corresponding to the minor stall range is the target stall level.

[0233] For example, in some embodiments, the stall level corresponding to the target stall detection range is determined as the target stall level, specifically including but not limited to the following step S5325:

[0234] S5325: In response to a rope retrieval speed or acceleration within the moderate stall range, determine the moderate stall level corresponding to the moderate stall range as the target stall level.

[0235] In some embodiments, if it is determined that the rope take-up speed or rope take-up acceleration of the strength training device is within the moderate stall range, then the moderate stall range is found in the correspondence between stall detection range and stall level, and the moderate stall level corresponding to the moderate stall range is determined as the target stall level.

[0236] For example, if the moderate stall range is between 1 m / s and 2 m / s or between 0.5 m / s 2 -1m / s 2 Between these times, the rope-reeling speed of the strength training equipment is 1.6 m / s or the rope-reeling acceleration is 0.75 m / s². 2 If the rope retrieval speed is 1.6 m / s, it falls within the moderate stall range of 1 m / s to 2 m / s, or the rope retrieval acceleration is 0.75 m / s². 2At 0.5m / s 2 -1m / s 2 The moderate stall range is determined by the correspondence between stall detection range and stall level, specifically between 1 m / s and 2 m / s or between 0.5 m / s. 2 -1m / s 2 The moderate stall level corresponding to the moderate stall range between these ranges is the target stall level.

[0237] For example, in some embodiments, the stall level corresponding to the target stall detection range is determined as the target stall level, specifically including but not limited to the following step S5326:

[0238] S5326: In response to a rope take-up speed or rope take-up acceleration within the severe stall range, determine the severe stall level corresponding to the severe stall range as the target stall level.

[0239] In some embodiments, if it is determined that the rope take-up speed or rope take-up acceleration of the strength training device is within the severe stall range, then the severe stall range is found in the correspondence between the stall detection range and the stall level, and the severe stall level corresponding to the severe stall range is determined as the target stall level.

[0240] For example, if the severe stall range is greater than 2 m / s or greater than 1 m / s 2 The rope-reeling speed of the strength training equipment is 2.4 m / s or the rope-reeling acceleration is 1.25 m / s². 2 If the rope retrieval speed of 2.4 m / s falls within the severe stall range (greater than 2 m / s), or the rope retrieval acceleration is 1.25 m / s², then... 2 greater than 1m / s 2 For severe stall ranges, the correlation between stall detection range and stall level is used to determine whether the speed is greater than 2 m / s or greater than 1 m / s. 2 The severe stall level corresponding to the severe stall range is the target stall level.

[0241] For example, in some embodiments, the strength training device is controlled to perform stall protection operations based on the target stall monitoring sub-mode, specifically including but not limited to the following step S5341:

[0242] S5341: In response to the target stall monitoring sub-mode being a minor stall monitoring mode, the tension applied by the control motor assembly to the traction rope assembly is reduced to a first value, and / or, a voice broadcast message is generated to instruct the user to adjust the action.

[0243] In this step, the stall monitoring sub-modes include mild stall monitoring mode, moderate stall monitoring mode, and severe stall monitoring mode. The stall protection operations performed by the strength training equipment differ depending on the sub-mode.

[0244] In some embodiments, if the target stall monitoring sub-mode is a minor stall monitoring mode, the strength training device responds by performing a first stall protection operation, including: controlling the tension applied by the motor assembly to the traction rope assembly to decrease from the current tension value to a first value, assisting the user in adjusting the action, and ensuring the user's personal safety.

[0245] In some embodiments, the first stall protection operation further includes: generating voice broadcast information and playing the voice broadcast information through a voice playback device or equipment to prompt the user to adjust their actions to ensure safety. The voice broadcast information is used to instruct the user to adjust their current actions, such as adjusting training or fitness movements.

[0246] For example, in some embodiments, the strength training device is controlled to perform stall protection operations based on the target stall monitoring sub-mode, specifically including but not limited to the following step S5342:

[0247] S5342: When the target stall monitoring sub-mode is the moderate stall monitoring mode, the tension applied by the control motor assembly to the traction rope assembly is reduced to a second value, and / or, a voice broadcast message is generated to instruct the user to perform stall protection processing, and / or, the tension applied by the control motor assembly to the traction rope assembly is reduced to a second value, and after a first preset time delay, the control motor assembly is retracted to the traction rope assembly, where the second value is less than the first value.

[0248] In some embodiments, if the target stall monitoring sub-mode is a moderate stall monitoring mode, the strength training device responds by performing a second stall protection operation, including: reducing the tension applied by the motor assembly to the traction rope assembly from the current tension value to a second value, so that the user can quickly end the training movement and leave the fitness area of ​​the strength training device, ensuring the user's personal safety. The second value is less than the first value.

[0249] In some embodiments, the second stall protection operation further includes: generating voice broadcast information and playing the voice broadcast information through a voice playback device or equipment to prompt the user to end the current training action and perform stall protection processing to ensure safety. The voice broadcast information is used to instruct the user to perform appropriate stall protection processing, such as releasing the traction cable assembly or leaving the fitness area of ​​the strength training equipment.

[0250] In some embodiments, the second stall protection operation further includes: reducing the tension applied by the control motor assembly to the traction rope assembly from the current tension value to a second value, and after maintaining the applied tension at the second value for a first preset duration, controlling the control motor assembly to retract the traction rope assembly to prepare for the next training session.

[0251] It is understood that designers can set a first preset duration based on the type of action, the performance parameters of the equipment, etc., and this application embodiment does not impose any limitations on this.

[0252] For example, in some embodiments, the strength training device is controlled to perform stall protection operations based on the target stall monitoring sub-mode, specifically including but not limited to the following step S5343:

[0253] S5343: The response target stall monitoring sub-mode is the severe stall monitoring mode. The tension applied by the control motor assembly to the traction rope assembly is reduced to the third value, and / or, a voice broadcast message is generated to instruct the user to perform stall protection processing, and / or, the tension applied by the control motor assembly to the traction rope assembly is reduced to the third value, and the display screen of the strength training equipment is controlled to display stall protection information, where the third value is less than or equal to the second value.

[0254] In some embodiments, if the target stall monitoring sub-mode is a severe stall monitoring mode, the strength training device responds by performing a third stall protection operation, including: reducing the tension applied by the motor assembly to the traction rope assembly from the current tension value to a third value, so that the user can quickly end the current training movement and leave the fitness area of ​​the strength training device, ensuring the user's personal safety. The third value is less than or equal to the second value.

[0255] In some embodiments, the third stall protection operation further includes: generating voice broadcast information and playing the voice broadcast information through a voice playback device or equipment to prompt the user to end the current training action and perform stall protection processing to ensure safety. The voice broadcast information is used to instruct the user to perform appropriate stall protection processing, such as releasing the traction cable assembly or leaving the fitness area of ​​the strength training equipment.

[0256] In some embodiments, the third stall protection operation further includes: controlling the motor assembly to reduce the tension applied to the traction rope assembly from the current tension value to a third value, and controlling the strength training device to display or present stall protection information on its display screen, reminding the user of the current operating status of the strength training device and the stall protection processing that needs to be performed. The stall protection information includes, but is not limited to, stall protection processing operations, the operating status of the strength training device, and the rope retraction time.

[0257] In some embodiments, the strength training device, in severe stall monitoring mode and after receiving a user's rope retraction operation on the display screen, controls the motor assembly to retract the traction rope assembly.

[0258] For example, in some embodiments, the stall protection method based on strength training equipment further includes, but is not limited to, the following step S5344:

[0259] S5344: When the target stall monitoring sub-mode is in severe stall monitoring mode and the display screen of the strength training equipment receives the rope retraction operation, the control motor assembly retracts the traction rope assembly.

[0260] In this step, if the target stall monitoring sub-mode is the severe stall monitoring mode, and the user is detected to have entered a rope retraction operation on the display screen of the strength training equipment or received a command to trigger the rope retraction operation, then the user has completed the stall protection process. In this case, a control command is sent to the motor assembly to start the motor assembly and retract the traction rope assembly at an appropriate retraction speed.

[0261] In some embodiments, the strength training equipment is controlled to perform stall protection operations based on the target stall monitoring mode, which includes, but is not limited to, the following steps S5301-S5303:

[0262] S5301: The response target stall monitoring mode is a high-risk stall monitoring mode, which controls the motor assembly to stop applying tension to the traction rope assembly.

[0263] S5302: The response target stall monitoring mode is a high-risk stall monitoring mode, which generates voice broadcast information to instruct the user to perform stall protection processing.

[0264] S5303: The response target stall monitoring mode is a high-risk stall monitoring mode, and the display screen of the control strength training equipment displays stall protection information.

[0265] In some embodiments, the target stall monitoring mode includes a high-risk stall monitoring mode. In this application embodiment, after detecting a stall in the strength training equipment and determining that the target stall monitoring mode is a high-risk stall monitoring mode, a stall protection process is triggered, controlling the strength training equipment to perform stall protection operations.

[0266] In step S5301, if the target stall monitoring mode is a high-risk stall monitoring mode, the system immediately enters the response state, sends a stop command to the motor assembly, controls the motor assembly to stop working, thereby stopping the motor assembly from applying tension to the traction rope assembly to prevent uncontrolled stall from occurring.

[0267] In step S5302, if the target stall monitoring mode is a high-risk stall monitoring mode, a pre-prepared, clear, and concise voice broadcast message is generated and played through an audio output system (such as a playback device, component, or equipment) to prompt the user to perform stall protection procedures. The voice broadcast message instructs the user to perform corresponding stall protection procedures and may include specific stall protection recommendations, such as, "Attention! The equipment has entered a high-risk stall state. Please stop operation immediately and check the equipment!"

[0268] In step S5303, if the target stall monitoring mode is a high-risk stall monitoring mode, the strength training equipment also sends a command to the display screen via the system interface to display or present stall protection information on the screen, reminding the user of the current working status of the strength training equipment. This stall protection information includes, but is not limited to, stall protection handling operations, the working status of the strength training equipment, and rope retraction time. For example, in some embodiments, the stall protection information includes the working status of the strength training equipment as: "Stall protection mode activated!" and the stall protection handling operation as: "Please end training, check the equipment, and perform necessary safety recovery operations!"

[0269] It should be noted that in the above embodiments, there is no necessarily a certain order between the steps. Those skilled in the art can understand from the description of the embodiments of this application that the steps may have different execution orders in different embodiments, that is, the steps may be executed in parallel or in interchange, etc.

[0270] In summary, the stall protection method based on a strength training device provided in this application includes a strength training device comprising a motor assembly and a traction rope assembly, wherein the motor assembly is used to drive the traction rope assembly to move, and the method comprises: determining the target movement type of the user training on the strength training device, determining the target stall monitoring mode corresponding to the target movement type, and controlling the strength training device to perform a stall protection operation based on the target stall monitoring mode.

[0271] This application embodiment determines the stall monitoring mode corresponding to the user's fitness movement type, and then controls the strength training equipment to perform stall protection operation according to the stall monitoring mode. In this way, the occurrence of the rope being retracted immediately after the stall protection is triggered can be reduced, reducing user panic and incorrect operation, reducing the risk of personal injury to the user, and providing safe training protection for the user.
