[0032] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

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

[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 based on the user's physical condition and training progress, which can easily lead to over- or undertraining and even sports injuries; complex operation and high learning costs affect user enthusiasm and persistence in participation. In addition, existing equipment generally lacks comprehensive safety protection mechanisms. When the user experiences emergencies such as exhaustion, the load cannot be reduced or eliminated in a timely manner, increasing the risk of injury. Finally, the functionality is relatively simple, focusing only on strength training, and failing to integrate social interaction and entertainment elements, making it difficult to stimulate users' long-term interest.

[0035] Based on the problems existing in the existing technology, please refer to Figures 1 to 3 The embodiment of the present invention provides an electromagnetic fitness device 10 that is safe, reliable, easy to operate, and has rich functions, so as to effectively meet the strength training needs of different groups of people in various scenarios.

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

[0037] Among them, the electromagnetic coil 200 is arranged on the frame 100, the permanent magnet 300 is movably arranged on the frame 100, the permanent magnet 300 is passed through the electromagnetic coil 200, the connecting rope 400 is movably arranged on the frame 100, and the connecting rope 400 is connected to the permanent magnet 300, and the connecting rope 400 is also used to connect to the lever.

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

[0039] It can be understood that the counterweight can be adjusted by changing the current flowing through the electromagnetic coil 200, thereby achieving precise control and real-time adjustment of the counterweight, and 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 counterweight methods, the operation process is effectively simplified, and the user does not need to manually replace the barbell plates or adjust the counterweight blocks, thereby improving the convenience of use; in addition, the electromagnetic fitness device 10 has a compact structure and light weight, and is suitable for use in various occasions such as home and office, and has a wide range of applicable scenarios.

[0040] Specifically, when the operator pulls down the connecting rope, the electromagnetic coil 200 can be energized to generate resistance when the electromagnetic coil 200 moves upward relative to the permanent magnet 300, thereby providing resistance for the operator's pulling down, thereby achieving the purpose of strength training; and, when the operator moves the connecting rope upward to reset, the electromagnetic coil 200 can also generate a downward force relative to the permanent magnet 300 to help the operator reset. It can be seen that the electromagnetic coil 200 and the permanent magnet 300 effectively help the operator to achieve exercise movements in the form of electromagnetic springs; not only that, the magnitude of the movement resistance generated by the electromagnetic coil 200 relative to the permanent magnet 300 can be adjusted by adjusting the current passing through the electromagnetic coil 200 to adapt to the different training needs of the operator, and the direction of the movement resistance generated by the electromagnetic coil 200 relative to the permanent magnet 300 can also be adjusted by adjusting the direction of the current passing through the electromagnetic coil 200 to adapt to the different training movements of the operator.

[0041] Furthermore, the frame 100 includes a crossbeam 110 and two longitudinal beam frames 120 , and both ends of the crossbeam 110 are respectively connected to the two longitudinal beam frames 120 , thereby forming a stable and firm frame 100 .

[0042] The two longitudinal beams 120 are both provided with an electromagnetic coil 200, a permanent magnet 300 and a connecting rope 400. The two connecting ropes 400 on the two longitudinal beams 120 are both connected to the lever, so that the lever is subjected to balanced force, which is convenient for users to use.

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

[0044] In this embodiment, the cross beam 110 and the two longitudinal beam frames 120 may 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, the electromagnetic coil 200 is arranged on the first longitudinal beam 121, the permanent magnet 300 is vertically and movably arranged in the first longitudinal beam 121 and connected to the connecting rope 400, the permanent magnet 300 can also be movably passed through the electromagnetic coil 200, and the connecting rope 400 is movably set on the first longitudinal beam 121.

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

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

[0048] Furthermore, the frame 100 also includes a pulley 500, and the longitudinal beam frame 120 also includes a second longitudinal beam 122, which 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 pulley 500.

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

[0050] By disposing the electromagnetic coil 200 and the permanent magnet 300 on the first longitudinal beam 121 and connecting the connecting rope 400 on the second longitudinal beam 122 to the lever, the stability of the electromagnetic fitness device 10 is improved.

[0051] In order to ensure the overall structural stability of the frame 100 , the longitudinal beam frame 120 further 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 both ends of the cross beam 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 a plurality of radial magnetizing rings 320 . The plurality of radial magnetizing rings 320 are sequentially connected and sleeved on the outer wall of the mounting rod 310 . Both 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 ring 320 is an N-pole, and the outer wall is an S-pole. Therefore, its magnetic lines of force are distributed radially, forming a closed magnetic circuit from the outer circle to the inner circle. This uniform magnetic field distribution allows the radially magnetized ring 320 to operate more smoothly and have a longer service life than the electromagnetic coil 200.

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

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

[0056] In this embodiment, the processor 600 may generate a PWM waveform (Pulse Width Modulation Wave) to drive the full-bridge circuit to control the current of the electromagnetic coil 200 .

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

[0058] Since there is a good linear relationship between the duty cycle of the PWM wave and the current, it is possible to achieve smooth and precise control of the coil current, thereby precisely adjusting the magnitude of the electromagnetic force. This adjustable electromagnetic force range can fully meet the user's strength training needs from low to medium intensity. For example, when performing movements such as bench presses, squats, or deadlifts, the device can provide an equivalent weight adjustment range of 10kg to 90kg (a total of 20kg to 180kg on the left and right sides). This design not only ensures the flexibility of the training load, but also can adapt 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 the received voice command information to the processor 600. The processor 600 is also used to control the current to increase or decrease based on the voice command information.

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

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

[0062] Furthermore, the Voice Interaction Module 700 is equipped with an advanced voice recognition chip, featuring a built-in recognition algorithm and keyword library optimized for strength training scenarios. It accurately identifies common commands such as "add 5kg," "subtract 10kg," and "stop." Recognition results are transmitted to the trainer's main control system via a 485 interface, enabling efficient voice control of the device. This design not only simplifies the operation process but also significantly enhances the user experience.

[0063] It can be understood that the processor 600 is usually provided with an execution module, which immediately starts the corresponding operating program after receiving the voice command information from the voice interaction module 700. When the processor 600 receives the voice command information of "add 5kg", the processor 600 will increase the current of the electromagnetic coil 200 accordingly through the control unit of the execution module. Since there is a good linear relationship between current and electromagnetic force, this operation will directly lead to an increase in electromagnetic force, thereby achieving an increase in equivalent counterweight. Conversely, when the system receives a "stop" command, the control unit will quickly cut off the power supply of the electromagnetic coil 200, causing the electromagnetic force to disappear instantly. At this time, under the action of auxiliary safety devices (such as spring buffers or dampers), the barbell bar will be smoothly guided to the initial position and automatically unload all the load, effectively ensuring the safety of the user. This design not only realizes real-time adjustment of the load during training, but also greatly improves the safety and convenience of equipment use.

[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. 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 can be, but is not limited to, a touch screen, which can display training data, device status, interactive information, events and other related content.

[0066] In practice, 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. When the recording reaches a preset time, the oldest data is automatically overwritten by the new data to ensure data storage continuity. Furthermore, the interface supports interaction with other devices or users, providing a more diverse user experience.

[0067] The touchscreen also offers a wealth of supplementary features, including instructional videos on various training subjects, detailed guidance on equipment usage and adjustments, and scientifically sound fitness recipe recommendations. This content not only helps users better master equipment usage techniques but also provides strong support for developing comprehensive fitness plans. This design allows users to more conveniently access the information they need, significantly improving their training effectiveness and experience.

[0068] Furthermore, the electromagnetic fitness device 10 includes a network communication module that supports convenient data transmission and interaction. Specifically, the device has a built-in Wi-Fi module or Ethernet interface and is compatible with the TCP / IP protocol, allowing for easy network connection with other similar training machines or supporting servers. This design not only allows users to synchronize their training data in real time, but also allows them to participate in a more intelligent and connected fitness experience, further enhancing training effectiveness and user convenience.

[0069] Dedicated event management software can also be installed on the server side, allowing users to sign up for various online strength training events, such as individual challenges or team relay races, directly through the training machine's human-computer interaction interface. During the event, the training machine will collect the user's training data (including the number of completed movements, weight, time, etc.) in real time and upload this data to the server. The server will perform statistics and rankings on the data according to the preset competition rules, and provide real-time feedback to the participating users. This mechanism not only enhances the fun and competitiveness of training, but also effectively stimulates the user's enthusiasm for participating in strength training, providing users 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 guarantee the user's training safety. For example:

[0071] Voice-controlled weight unloading: When the system receives a voice command of "stop," it quickly cuts off the power to the electromagnetic coil 200, instantly removing the weight from the barbell. This feature can quickly resolve danger in an emergency, ensuring user safety.

[0072] Foot-operated emergency stop switch: The device is also designed with a foot-operated emergency stop switch, located within easy reach of the user. In the event of an accident, a simple touch of the foot switch will immediately cut off the power supply to the entire device, causing it to completely stop operating and providing immediate protection for the user.

[0073] Structural Protection: The device incorporates a physical blocking mechanism into its design. Whether performing high-risk exercises like the bench press or squats, even if an accident occurs due to operator error, the barbell will be effectively blocked before it reaches the user, preventing any harm.

[0074] Through the above 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, the embodiments of the present invention provide an electromagnetic fitness device 10. By applying a DC voltage to the electromagnetic coil 200, the electromagnetic coil 200 generates an electromagnetic attraction on the permanent magnet 300. This attraction acts on the connecting rope 400 connected to the permanent magnet 300, creating resistance to its movement relative to the fixed frame 100. Users can achieve strength training by pulling the lever or connecting rope 400. Furthermore, the voltage applied to the electromagnetic coil 200 can be adjusted in real time to precisely control and dynamically adjust the training intensity. This flexibility allows for personalized adjustment of training intensity based on the user's physical condition and training progress, effectively reducing the risk of sports injuries. Compared to traditional mechanical weight-balancing methods, users do not need to manually replace barbell plates or adjust weights, significantly simplifying the operation process and improving ease of use. Furthermore, the electromagnetic fitness device 10 features a compact design, light weight, and small size, making it ideal for use in spaces limited, such as homes and offices, and offering a wide range of applicability. This innovative technology not only optimizes the user experience but also opens up new possibilities for modern fitness.

[0076] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
