The overall structure of the elliptical bike consists of a frame 11 component 1, a power component 2, a resistance adjustment component 3, a seat component 4, and a control component 5. These components work together through mechanical and electrical connections. The frame 11 component 1 is the basic structure of the elliptical bike, including the frame 11 and frame armrests 12. The frame 11 is the main supporting structure of the device and connects to the other components. The frame armrests 12 are hinged to the frame 11, allowing users to grip them during exercise, providing stability and support. The power component 2 is the core part of the elliptical bike, including the power pedal 21 and the power armrests 22. The rotating shaft 23 and connecting rod 24 are connected. One end of the power pedal 21 is hinged to the power handlebar 22, and the other end is connected to the rotating shaft 23 via the connecting rod 24. The power handlebar 22 is fixed to the frame 11. The user achieves bidirectional drive by stepping on the power pedal 21 and pushing the power handlebar 22, which drives the rotating shaft 23 to rotate around its axis.

The magnet 334 is fixed above the sliding disk 332. The resistance is dynamically adjusted by changing the distance between the magnet 334 and the resistance disk 32. In other words, when the resistance needs to be adjusted, the control unit manipulates the first drive unit 333, which pushes the sliding disk 332 along the sliding disk movement direction 335, moving the sliding disk 332 from the power disk 31 to below the resistance disk 32. The magnets 334 on 32 attract each other, generating resistance. The seat assembly 4 provides a comfortable riding posture for the user, including a seat bracket 41 and a seat cushion 42. The seat bracket 41 is fixed to the frame 11, and the seat cushion 42 is installed on the seat bracket 41. The height and angle can be adjusted according to the user's needs. The control assembly 5 is responsible for the overall control of the system, including a control unit and a control button 51. The control button 51 is installed on the frame armrest 12. The user can operate the control unit through the button to adjust the resistance or other functions. The control unit is electrically connected to the first drive unit 333 and controls the movement of the sliding disk 332 through electrical signals, thereby realizing the automation and intelligence of resistance adjustment. The elliptical bike as a whole provides the user with an efficient, flexible and comfortable exercise experience through the bidirectional drive of the power assembly 2, the magnetic control module of the resistance adjustment assembly 3, and the comfort of the seat assembly 4. The coordinated work of each component ensures the stability and functionality of the equipment, while the intelligent design of the control assembly 5 enhances the user experience.

[0057] In this embodiment, the bidirectional drive of the power component 2 allows users to exercise both upper and lower limbs simultaneously during cycling, improving exercise efficiency and catering to various fitness needs. The resistance adjustment component 3 achieves stepless adjustment through a magnetic control module, allowing users to quickly adjust the resistance level according to their needs and adapt to different exercise intensities. The sliding disc 332 moves along the slide rail 331, ensuring the accuracy and stability of the adjustment. The seat component 4's seat bracket 41 and seat cushion 42 provide users with good support and comfort, reducing fatigue during long-term cycling. The height and angle of the seat cushion 42 are adjustable to accommodate different user body types and needs. The control component 5, through the cooperation of the control button 51 and the control unit, achieves automated and convenient resistance adjustment. Users do not need to manually adjust mechanical parts, improving operational convenience and the intelligence level of the equipment. The reasonable layout of the frame component 11 and various functional modules ensures a compact overall structure of the equipment. At the same time, the hinge and transmission connections enhance the stability and durability of the equipment. It not only meets the user's exercise needs but also provides an efficient, flexible, and comfortable user experience, suitable for various scenarios such as home and gym.

[0058] Please see Figure 1 , Figure 2 , Figure 3 In some embodiments, the resistance adjustment assembly 3 further includes a protective cover 34, which is disposed on the frame 11 and covers the resistance adjustment assembly 3.

[0059] In this embodiment, the resistance adjustment component 3 of the elliptical bike also includes a protective cover 34. The protective cover 34 is disposed on the frame 11 and covers the resistance adjustment component 3. The protective cover 34 provides additional safety protection to prevent users from accidentally contacting the moving parts of the resistance adjustment component 3 during use, thereby avoiding possible pinching or scratching accidents. The protective cover 34 is usually made of a material with certain strength and toughness, such as engineering plastics or metal, to ensure that it can effectively resist external impacts and wear from long-term use. Preferably, the protective cover 34 also takes into account the need for ventilation and heat dissipation to ensure that the heat generated by the resistance adjustment component 3 during operation can be dissipated in a timely manner, thereby extending the service life of the component and maintaining its performance stability.

[0060] In this embodiment, the protective cover 34 effectively isolates the user from the moving parts of the resistance adjustment component 3, reducing the risk of accidental injury during exercise. The protective cover 34 provides additional physical protection for the resistance adjustment component 3, reducing damage caused by external impacts or foreign objects entering, while also helping to prevent the accumulation of dust and dirt, thereby reducing maintenance frequency and costs. The protective cover 34 can be coordinated with the overall appearance of the elliptical bike, making the equipment look cleaner and more professional, and enhancing the product's market competitiveness.

[0061] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 In some embodiments, one end of the slide rail 331 is laid below the power plate 31, and the other end of the slide rail 331 is arranged on the inner wall of the protective cover 34 along the periphery of the resistance plate 32.

[0062] In this embodiment, the slide rail 331 in the resistance adjustment assembly 3 of the elliptical cart has been optimized. Specifically, one end of the slide rail 331 is laid below the power disk 31, making full use of the space, while the other end of the slide rail 331 is set along the periphery of the resistance disk 32 on the inner wall of the protective cover 34. This not only ensures the stability of the slide rail 331 during movement but also makes full use of the internal space of the protective cover 34, achieving a compact and rational structure. The slide rail 331 is a component used to support and guide the sliding disk 332 to move along a predetermined path. It is typically made of metal or high-strength plastic, with a smooth surface and precise dimensions to ensure the smooth movement of the sliding disk 332. The laying method allows the sliding disk 332 to move smoothly on the slide rail 331, thereby precisely adjusting the distance between the magnet 334 and the resistance disk 32, achieving stepless adjustment of resistance. It can be understood that when the resistance needs to be adjusted, the control unit controls the first drive unit 333, which pushes the sliding disk 332 along the sliding disk movement direction 335, pushing the sliding disk 332 from the power disk 31 to the side of the resistance disk 32. The magnet 334 on the resistance disk 32 and the sliding disk 332 attract each other, generating resistance. Since moving to the side of the resistance disk 32 is larger than moving only below the resistance disk 32, the range of attraction with the resistance disk 32 is larger, and the range of resistance generated is also larger.

[0063] In this embodiment, the two ends of the slide rail 331 are fixed to the power plate 31 and the protective cover 34 respectively, which effectively prevents the slide rail 331 from shifting or loosening during movement, thereby reducing the risk of the user contacting the moving parts and improving the overall safety of the equipment. The way the slide rail 331 is laid ensures the stability of the slide rail 331 during the user's movement, reducing the deformation or damage of the slide rail 331 caused by vibration or external force, thereby improving the accuracy and reliability of resistance adjustment. The slide rail 331 is set on the inner wall of the protective cover 34 along the periphery of the resistance plate 32, making the entire resistance adjustment assembly 3 neater and more compact.

[0064] Please see Figure 1 , Figure 2 , Figure 6In some embodiments, the seat assembly 4 further includes a first adjustment group 43, which includes a first adjustment frame, a first adjustment knob, a first adjustment rod, and a first adjustment post.

[0065] In this embodiment, the seat assembly 4 further includes a first adjustment group 43, which is disposed on the seat bracket 41. The first adjustment group 43 includes a first adjustment frame, a first adjustment knob, a first adjustment rod, and a first adjustment post. The seat cushion 42 is fixed on the first adjustment post. The first adjustment frame is sleeved below the first adjustment post to support and guide the movement of the first adjustment post. The first adjustment post, through its cooperation with the first adjustment frame, drives the seat cushion 42 to move back and forth within the first adjustment frame, thereby adjusting the position of the seat cushion 42. A first fixing hole is provided at the bottom of the first adjustment frame for fixing the first adjustment rod. The first adjustment post is provided with multiple first adjustment holes, which cooperate with the first fixing holes. The seat cushion 42 is locked in position via a threaded connection.

Users can adjust the seat cushion 42 to different positions by rotating the first adjustment knob and inserting the first adjustment rod into different first adjustment holes, thus achieving precise adjustment of the seat cushion 42 position. Users can easily adjust the seat cushion 42 to the most suitable position according to their body shape and usage habits, improving the comfort of exercise.

[0066] In this embodiment, the user can easily adjust the fore-and-aft position of the seat cushion 42 by rotating the first adjustment knob to obtain a more comfortable exercise posture according to their own needs. The first adjustment group 43 adopts a threaded connection to ensure the stability of the seat cushion 42 after adjustment and avoid displacement or loosening during use. The seat cushion 42 is fixed to the seat bracket 41 through the first adjustment group 43, making the replacement and maintenance of the seat cushion 42 more convenient. The adjustability of the seat cushion 42 allows the user to adjust the position of the seat cushion 42 as needed, reducing wear caused by fixed position and extending the service life of the seat cushion 42.

[0067] Please see Figure 1 , Figure 2 , Figure 6In some embodiments, the seat assembly 4 further includes a second adjustment group 44, which includes a second adjustment frame 441, a second adjustment knob 442, and a second adjustment rod 443.

The second adjustment rod 443 is provided with threads. The second adjustment hole is provided with threads inside. The diameters of the second adjustment hole and the second fixing hole are adapted to the diameter of the second adjustment rod 443.

[0068] In this embodiment, the seat assembly 4 further includes a second adjustment group 44, which includes a second adjustment frame 441, a second adjustment knob 442, and a second adjustment rod 443. The second adjustment frame 441 is disposed on the frame 11 and sleeved on the outside of the seat bracket 41, providing an adjustable support structure for the seat bracket 41. The second adjustment frame 441 is provided with a second fixing hole for fixing the second adjustment rod 443. The seat bracket 41 is provided with multiple second adjustment holes, which cooperate with the second fixing holes to lock the position of the seat bracket 41 through threaded connection. The second adjustment knob 442 is fixedly connected to the second adjustment rod 443, which is provided with threads, and the interior of the second adjustment hole is also provided with threads. The threaded design allows the second adjusting rod 443 to screw into the second adjusting hole. The diameters of the second adjusting hole and the second fixing hole are matched with the diameter of the second adjusting rod 443, ensuring the stability and reliability of the connection. By rotating the second adjusting knob 442, the user can adjust the second adjusting rod 443 in different second adjusting holes on the seat bracket 41, thereby moving the seat bracket 41 up and down along the second adjusting frame 441 to adjust the seat height or angle. This allows users to easily adjust the seat height or angle according to their body type and usage habits, thus obtaining a more comfortable riding experience. The structure of the second adjusting group 44 ensures the smoothness and stability of the adjustment process, while providing multiple adjustment positions to meet the needs of different users.

[0069] In this embodiment, users can easily adjust the height or angle of the seat by rotating the second adjustment knob 442 to obtain a more comfortable riding posture according to their own needs.

[0070] Please see Figure 1 , Figure 2 , Figure 3 In some embodiments, the resistance adjustment component 3 further includes a speed sensor 35, which is disposed inside the protective cover 34 and is electrically connected to the first drive unit 333 and the control component 5.

[0071] In this embodiment, the resistance adjustment component 3 further includes a speed sensor 35, which is disposed inside the protective cover 34 and electrically connected to the first drive unit 333 and the control component 5. The speed sensor 35 is used to monitor the rotational speed of the rotating shaft 23 in real time and transmit the speed data to the control component 5. The control component 5 controls the operation of the first drive unit 333 through electrical connection based on the speed data and the resistance level set by the user, thereby adjusting the resistance. The speed sensor 35 typically uses a high-precision Hall sensor or encoder, which can capture the rotational frequency of the rotating shaft 23 and output corresponding pulse signals.
