[0032] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0033] Strength training is crucial for increasing muscle strength, improving bone density, preventing falls, and enhancing quality of life. However, traditional fitness equipment, such as the Smith machine, is only suitable for commercial environments and cannot meet the needs of home and office settings.

[0034] Specifically, traditional fitness equipment such as the Smith machine has the following shortcomings: Limited flexibility in weight distribution, making it impossible to adjust the load in real time according to the user's physical condition and training progress, easily leading to overtraining or undertraining, and potentially causing sports injuries; complex operation and high learning costs, affecting user engagement and consistency. Furthermore, existing equipment generally lacks comprehensive safety mechanisms, failing to promptly reduce or eliminate the load in case of emergencies such as user fatigue, increasing the risk of injury. Finally, its functionality is relatively limited, focusing solely on strength training and failing to incorporate social interaction and entertainment elements, making it difficult to motivate users to maintain long-term engagement.

[0035] Based on the problems existing in the current technology, please refer to Figures 1 to 3 This utility model provides a safe, reliable, easy-to-operate, and feature-rich electromagnetic fitness device 10 to effectively meet the strength training needs of different groups of people in various scenarios.

[0036] In detail, the electromagnetic fitness device 10 includes a frame 100, an electromagnetic coil 200, a permanent magnet 300, and a connecting rope 400.

[0037] The electromagnetic coil 200 is disposed on the frame 100, the permanent magnet 300 is movably disposed on the frame 100, the permanent magnet 300 passes through the electromagnetic coil 200, the connecting rope 400 is movably disposed on the frame 100, and the connecting rope 400 is connected to the permanent magnet 300. The connecting rope 400 is also used to connect with the lever.

[0038] In this embodiment, by applying a DC voltage to the electromagnetic coil 200, the electromagnetic coil 200 generates an electromagnetic attraction force on the permanent magnet 300, thereby making the connecting rope 400 connected to the permanent magnet 300 have a moving resistance relative to the frame 100, thus achieving the purpose of strength training by moving the lever and the connecting rope 400.

[0039] It is understandable that the weight can be adjusted by changing the current flowing through the electromagnetic coil 200, thus achieving precise control and real-time adjustment of the weight. The training intensity can be flexibly adjusted according to the user's physical condition and training progress, reducing the risk of sports injuries. Compared with traditional mechanical weight methods, it effectively simplifies the operation process. Users do not need to manually change barbell plates or adjust weight blocks, improving ease of use. In addition, the electromagnetic fitness device 10 has a compact structure and is lightweight, making it suitable for use in various occasions such as home and office, with a wide range of applications.

[0040] Specifically, during the process of the operator pulling down the connecting rope, energizing the electromagnetic coil 200 causes it to generate resistance relative to the permanent magnet 300 as it moves upward, thus providing resistance for the operator's pull-down and achieving the purpose of strength training. Furthermore, when the operator moves the connecting rope upward to return to its original position, the electromagnetic coil 200 also provides downward assistance relative to the permanent magnet 300, helping the operator return to the original position. It is evident that the electromagnetic coil 200 and the permanent magnet 300, acting as an electromagnetic spring, effectively assist the operator in achieving the exercise movement. Moreover, the magnitude of the resistance generated by the electromagnetic coil 200 relative to the permanent magnet 300 can be adjusted by changing the current flowing through the electromagnetic coil 200 to suit different training needs. The direction of the resistance can also be adjusted by changing the direction of the current flowing through the electromagnetic coil 200 to suit different training movements.

[0041] Furthermore, the frame 100 includes a crossbeam 110 and two longitudinal beams 120, with both ends of the crossbeam 110 connected to the two longitudinal beams 120 respectively, thereby forming a stable and sturdy frame 100.

[0042] Both longitudinal beams 120 are equipped with electromagnetic coils 200, permanent magnets 300 and connecting ropes 400. The two connecting ropes 400 on the two longitudinal beams 120 are connected to the lever, which can make the lever bear force evenly and make it easy for users to use.

[0043] It is understandable that the crossbeam 110 can also be used as a lever to facilitate users to do training exercises such as pull-ups, thereby improving the practicality of the electromagnetic fitness device 10.

[0044] In this embodiment, the crossbeam 110 and the two longitudinal beams 120 can be connected by welding or high-strength bolts to ensure that the overall structure has a high degree of stability and safety.

[0045] In detail, the longitudinal beam frame 120 includes a first longitudinal beam 121, an electromagnetic coil 200 disposed in the first longitudinal beam 121, a permanent magnet 300 vertically and movably disposed in the first longitudinal beam 121 and connected to a connecting rope 400, the permanent magnet 300 can also be movably inserted through the electromagnetic coil 200, and the connecting rope 400 is movably disposed in the first longitudinal beam 121.

[0046] Furthermore, the first longitudinal beam 121 includes a mounting component 1211 and connecting rods 1212 connected to both ends of the mounting component 1211. An electromagnetic coil 200 is sleeved on the mounting component 1211, and a permanent magnet 300 is movably disposed inside the mounting component 1211 and the connecting rods 1212.

[0047] In this embodiment, the two connecting rods 1212 are of the same length, so that the mounting member 1211 is located at the exact center of the first longitudinal beam 121 in the height direction.

[0048] Furthermore, the frame 100 also includes pulleys 500, and the longitudinal beam frame 120 also includes a second longitudinal beam 122. The second longitudinal beam 122 is spaced apart from the first longitudinal beam 121. The top and bottom ends of the first longitudinal beam 121 and the second longitudinal beam 122 are both provided with pulleys 500, and the connecting rope 400 is wound around the pulleys 500.

[0049] As shown in the figure, the connecting rope 400 is sequentially wound around the pulleys 500 at the top and bottom of the first longitudinal beam 121 and the pulleys 500 at the bottom and top of the second longitudinal beam 122 and connected end to end, thereby improving the overall structural stability.

[0050] The stability of the electromagnetic fitness device 10 is improved by setting the electromagnetic coil 200 and the permanent magnet 300 on the first longitudinal beam 121 and connecting the connecting rope 400 located at the second longitudinal beam 122 to the lever.

[0051] To ensure the overall structural stability of the frame 100, the longitudinal beam frame 120 also includes a top beam 130. The first longitudinal beam 121 and the second longitudinal beam 122 are both connected to the top beam 130, and the two ends of the crossbeam 110 are respectively connected to the top beams 130 of the two longitudinal beam frames 120.

[0052] Furthermore, the permanent magnet 300 includes a mounting rod 310 and multiple radially magnetized magnetic rings 320. The multiple radially magnetized magnetic rings 320 are connected in sequence and sleeved on the outer wall of the mounting rod 310. The two ends of the mounting rod 310 are connected to the connecting rope 400.

[0053] As shown in the figure, the inner wall of the radially magnetized magnetic ring 320 has N poles and the outer wall has S poles. Therefore, its magnetic field lines are distributed along the radial direction, forming a closed magnetic circuit from the outer circle to the inner circle. Due to its uniform magnetic field distribution, the radially magnetized magnetic ring 320 can operate more smoothly than the electromagnetic coil 200 and has a longer service life.

[0054] It can be seen that the permanent magnet 300 formed by using multiple radially magnetized magnetic rings 320 connected in sequence can generate a stronger and more uniform magnetic field. Compared with traditional magnets, the radially magnetized magnetic rings 320 can reduce the volume and weight under the same magnetic field strength, further improving the adaptability of the electromagnetic fitness device 10.

[0055] Furthermore, the electromagnetic fitness device 10 also includes a processor 600, with the electromagnetic coil 200 electrically connected to the processor 600. The processor 600 is used to input current into the electromagnetic coil 200 and control the current to increase or decrease.

[0056] In this embodiment, the processor 600 can drive the full-bridge circuit to control the current of the electromagnetic coil 200 by generating a PWM waveform (Pulse width modulation wave).

[0057] After the processor 600 receives the user's instruction information, it calculates the counterweight weight information, converts the counterweight weight information into current information, and adjusts the duty cycle of the PWM wave accordingly, so that the magnitude of the electromagnetic force generated by the electromagnetic coil 200 on the permanent magnet 300 is the same as the magnitude of the force corresponding to the counterweight weight information.

[0058] Because of the excellent linear relationship between the duty cycle of the PWM wave and the current, smooth and precise control of the coil current can be achieved, thereby accurately adjusting the magnitude of the electromagnetic force. This adjustable electromagnetic force range can fully meet the user's strength training needs from low to moderate intensity. For example, when performing exercises such as bench press, squat, or deadlift, the device can provide an equivalent weight adjustment range of 10kg to 90kg (20kg to 180kg for both sides combined). This design not only ensures the flexibility of training load but also adapts to the personalized needs of different users.

[0059] Furthermore, the electromagnetic fitness device 10 also includes a voice interaction module 700, which is electrically connected to the processor 600. The voice interaction module 700 is used to transmit received voice command information to the processor 600, and the processor 600 is also used to control the current to increase or decrease based on the voice command information.

[0060] It is understood that the voice interaction module 700 includes a microphone for receiving voice command information.

[0061] To further enhance the ease of operation of the electromagnetic fitness device 10, a high-sensitivity microphone array can be installed near the control panel of the processor 600. This ensures that the array can effectively capture the user's voice commands during training and filters out ambient noise interference through noise reduction technology, thereby ensuring the accuracy and stability of voice recognition.

[0062] Furthermore, by equipping the voice interaction module 700 with an advanced voice recognition chip, and incorporating a recognition algorithm and keyword library optimized specifically for strength training scenarios, it can accurately recognize common commands such as "add 5kg," "decrease 10kg," and "stop." The recognition results are transmitted to the training machine's main control system via a 485 interface, enabling efficient voice control of the equipment. This design not only simplifies the operation process but also significantly enhances the user experience.

[0063] It is understandable that the processor 600 typically contains an execution module that immediately initiates the corresponding operation program upon receiving voice commands from the voice interaction module 700. When the processor 600 receives the voice command "add 5kg", it increases the current to the electromagnetic coil 200 through the control unit of the execution module. Since there is a good linear relationship between current and electromagnetic force, this operation directly leads to an increase in electromagnetic force, thus increasing the equivalent counterweight. Conversely, when the system receives a "stop" command, the control unit quickly cuts off the power to the electromagnetic coil 200, causing the electromagnetic force to disappear instantly. At this time, with the assistance of safety devices (such as spring buffers or dampers), the barbell is smoothly guided back to its initial position and the entire load is automatically unloaded, effectively ensuring the user's safety. This design not only enables real-time adjustment of the load during training but also greatly improves the safety and convenience of using the equipment.

[0064] Furthermore, the electromagnetic fitness device 10 also includes a touch interaction module 800, which is electrically connected to the processor 600. The touch interaction module 800 is used to transmit received user information to the processor 600, and the processor 600 is also used to control the current to increase or decrease based on the user information.

[0065] In this embodiment, the touch interaction module 800 may be, but is not limited to, a touch screen, which can display training data, device status, interactive information, and competition-related content.

[0066] In practical applications, the touch interaction module 800 allows users to select training subjects and set personalized information. It also records and saves relevant parameters for each training session, including training items, duration, and intensity. Once a preset time has elapsed, the oldest data is automatically overwritten by newer data, ensuring data storage continuity. Furthermore, the interface supports interaction with other devices or users, providing a more diverse user experience.

[0067] In addition to its core functions, the touchscreen offers a wealth of auxiliary features, including instructional videos for various training subjects, detailed guidance on equipment use and adjustment, and scientifically sound fitness meal plan recommendations. This content not only helps users better master the equipment's operation but also provides strong support for developing comprehensive fitness plans. This design allows users to more easily access the information they need, significantly improving training effectiveness and overall experience.

[0068] Furthermore, the electromagnetic fitness device 10 also includes a network communication module, which supports convenient data transmission and interaction functions. Specifically, the device has a built-in Wi-Fi module or Ethernet interface and is compatible with the TCP / IP protocol, enabling easy network connection with other similar training machines or accompanying servers. Through this design, users can not only synchronize training data in real time, but also participate in more intelligent and interconnected fitness experiences, further improving training effectiveness and ease of use.

[0069] On the server side, dedicated competition management software can be installed, allowing users to directly register for various online strength training competitions, such as individual challenges or team relay races, through the training machine's human-computer interaction interface. During the competition, the training machine collects users' training data in real time (including the number of repetitions, weight, and time), and uploads this data to the server. The server then calculates and ranks the data according to preset competition rules and provides the results back to the participating users in real time. This mechanism not only enhances the fun and competitiveness of training but also effectively motivates users to participate in strength training, providing them with a richer and more interactive training experience.

[0070] It is also important to emphasize that the electromagnetic fitness device 10 is equipped with a safety protection mechanism to fully ensure the user's training safety. For example:

[0071] Voice-controlled unloading of counterweight: When the system receives a "stop" voice command, it will quickly cut off the power to the electromagnetic coil 200, causing the counterweight load on the barbell to disappear instantly. This function can quickly eliminate danger in emergencies and ensure the user's safety.

[0072] Foot-operated emergency stop switch: The device is also equipped with a foot-operated emergency stop switch, located within easy reach of the user. In case of an accident, simply touch the foot switch to immediately cut off the power supply to the entire device, bringing it to a complete stop and providing immediate protection for the user.

[0073] Structural protection: The device incorporates a physical blocking mechanism in its structural design. Whether performing high-risk exercises such as bench presses or squats, even if an accident occurs due to operational errors, the barbell will be effectively blocked before it touches the body, thus preventing any injury to the user.

[0074] Through these safety protection measures, the electromagnetic fitness device 10 not only improves the safety of training, but also allows users to focus more on the exercise process without worrying about potential risks.

[0075] In summary, this utility model provides an electromagnetic fitness device 10. By applying a DC voltage to an electromagnetic coil 200, the electromagnetic coil 200 generates an electromagnetic attraction force on a permanent magnet 300. This attraction force acts on a connecting rope 400 connected to the permanent magnet 300, causing it to generate resistance relative to the fixed frame 100. Users can achieve strength training by pulling the lever or the connecting rope 400. Furthermore, the weight can be adjusted in real time by changing the voltage on the electromagnetic coil 200, thereby achieving precise control and dynamic adjustment of training intensity. This flexibility allows for personalized adjustments to training intensity based on the user's actual physical condition and training progress, effectively reducing the risk of sports injuries. Compared to traditional mechanical weight methods, users do not need to manually change barbell plates or adjust weight blocks, greatly simplifying the operation process and improving ease of use. In addition, the electromagnetic fitness device 10 features a compact design, is lightweight and small in size, making it ideal for use in spaces with limited space, such as homes and offices, and has wide applicability. This innovative technology not only optimizes the user experience but also provides more possibilities for modern fitness methods.

[0076] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
