Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, and in particular to a hybrid power fitness device. Background Technology

[0002] Resistance training components in fitness equipment are the core components for strength training. They enhance muscle strength, endurance, and explosive power by applying mechanical resistance. Common resistance training components in fitness equipment on the market include magnetic resistance components, hydraulic resistance components, weight block resistance components, and magnetic powder resistance components. Although these resistance training components can provide resistance training for trainees, they generally have the drawback of only providing unidirectional resistance and not being able to achieve recovery force regulation. They only provide load during the exertion phase, and trainees must rely entirely on their own strength to overcome inertia during the return phase. This results in decreased movement continuity and reduced exercise efficiency.

[0003] The shortcomings of fitness equipment that cannot provide retraction force adjustment are particularly prominent in home and women's fitness settings: on the one hand, the diverse training needs of trainees (such as cushioning assistance for rehabilitation training and bidirectional force feedback for shaping exercises) cannot be met, and the joints of trainees are prone to injury due to the lack of retraction force cushioning; on the other hand, traditional equipment with bidirectional force adjustment relies on complex mechanical structures (such as dual motors and hydraulic energy storage devices), which leads to a surge in overall cost and bulky size, making it difficult to adapt to the lightweight requirements of home spaces and the dual demands of female users for economy and ease of operation.

[0004] In conclusion, there is an urgent need in the market for a fitness device that combines both recovery force and resistance functions at a low cost, especially in the fields of smart home fitness equipment and women's-specific equipment. Utility Model Content

[0005] The purpose of this invention is to provide a hybrid fitness device that uses a resistance device and a drive motor to provide recovery force and resistance at a low cost, thereby solving the bottleneck of the unidirectional resistance experience in existing resistance training components and the cost contradiction of traditional bidirectional force devices.

[0006] To achieve the above objectives, this technical solution provides a hybrid power fitness device, including: a tension component; a drive motor and a resistance device connected via a one-way bearing; the tension component is driven to the one-way bearing via a transmission component; when the tension component is in resistance training mode, both the resistance device and the drive motor are driven to the one-way bearing; when the tension component is in tension recovery mode, the drive motor is connected to the one-way bearing to provide recovery force to the tension component; the tension component is defined to be in resistance training mode when it is pulling away from the drive motor, and to be in tension recovery mode when it is moving towards the drive motor.

[0007] Compared with existing technologies, this technical solution has the following characteristics and beneficial effects:

[0008] This solution utilizes the unidirectional transmission characteristics of one-way bearings to achieve automatic connection / disconnection between the drive motor and the resistance device without the need for additional sensors or electronic control systems. During resistance training, the one-way bearing drives both components to work together to provide resistance; during pull recovery, the one-way bearing automatically disengages from the resistance device, and only the drive motor operates. This provides a hybrid powertrain for fitness equipment. Compared to traditional hybrid powertrains that rely on electronic control systems, this solution simplifies the control logic through mechanical structure and uses standardized components such as one-way bearings and belts, reducing hardware costs and maintenance complexity. Furthermore, the transmission component uses belt drive, which utilizes its elasticity to buffer sudden force exerted by the user, avoiding vibration, noise, or damage caused by rigid transmission, extending equipment life and improving exercise comfort. Simultaneously, by changing the pulley diameter, the transmission ratio can be flexibly adjusted to amplify the response speed or driving torque of the resistance device, adapting to complex conditions such as strength training or high-frequency, fast training.

[0009] In another embodiment, this solution additionally includes a clutch assembly that allows the clutch to switch engagement positions between the tension assembly and the secondary drive pulley: in the first engagement position, the tension assembly can be used independently (e.g., in rowing machine mode); in the second engagement position, it can quickly connect to peripheral devices such as treadmills and fly stations via the secondary drive pulley, providing hybrid power for various fitness devices and achieving "one machine for multiple uses." No additional power source is required, reducing the cost for users to purchase multiple devices and expanding the equipment's usage scenarios. Attached Figure Description

[0020] Example 1

[0021] like Figure 1 As shown, this solution provides a hybrid power fitness device, including:

[0022] Tension assembly 30;

[0023] A drive motor 10 and a resistance device 20 are coupled together via a one-way bearing 60;

[0024] The tension component 30 is connected to the one-way bearing 60 via the transmission component 40. When the tension component 30 is in the resistance training state, the resistance component 20 and the drive motor 10 are both connected to the one-way bearing 60. When the tension component 30 is in the tension recovery state, the drive motor 10 is connected to the one-way bearing 60 to provide recovery force for the tension component 30.

[0025] This solution defines the tension component 30 as being in a resistance training state when it is pulled away from the drive motor 10, and defines the tension component 30 as being in a tension recovery state when it is moved towards the drive motor 10.

[0026] This solution uses a one-way bearing 60 to coordinate the drive motor 10 and the resistance device 10, enabling dynamic switching between resistance training and pull recovery without increasing costs excessively, thus providing the fitness industry with hybrid fitness equipment that can generate recovery force.

[0027] Regarding the one-way bearing 60 in this solution:

[0028] The resistance device 20 and the drive motor 10 are located at both ends of the one-way bearing 60. One end of the one-way bearing 60 is connected to the motor output shaft 11 of the drive motor 10, and the other end is connected to the resistance device 20. The tension component 30 is sleeved on the outside of the one-way bearing 60 through the transmission component 40.

[0029] Specifically, such as Figure 4 As shown, the one-way bearing 60 of this solution includes an integrally formed resistance device connecting section 61, a transmission component connecting section 62, and a motor connecting section 63. The motor connecting section 63 is internally connected to the motor output shaft 11 of the drive motor 10. The transmission component 40 is sleeved on the surface of the transmission component connecting section 62, and the output shaft of the resistance device 20 is placed inside the resistance device connecting section 61.

[0030] More specifically, a first through hole 64 is formed inside the resistance device connecting section 61 of the one-way bearing 60, and a second through hole 65 is formed inside the transmission component connecting section 62 and the motor connecting section 63. The first through hole 64 and the second through hole 65 are connected, and the diameter of the first through hole 64 is larger than that of the second through hole 65. The motor output shaft 11 of the drive motor 10 is placed inside the second through hole 65, and the output shaft of the resistance device 20 is placed inside the first through hole 64.

[0031] In some embodiments, the outer surface of the motor output shaft 11 is designed with external threads, the inner side of the motor connection section 63 is provided with internal threads, the motor output shaft 11 and the motor connection section 62 are connected by threaded engagement, and the motor output shaft 11 of the drive motor 10 passes through the second through hole 65 to connect with the one-way bearing 60.

[0032] In some embodiments, the second through hole 65 is designed as a non-complete circular hole shape, that is, the cross section of the second through hole 65 is a closed loop cross section composed of a circular arc and a horizontal bar. The advantage of this design is that it facilitates the motor output shaft 11 to pass through the D-type transition fit and prevents slippage.

[0033] In some embodiments, the outer surface of the transmission component connecting section 62 is provided with threads, and the transmission component 40 is sleeved on the outer surface of the transmission component connecting section 62.

[0034] In some embodiments, a recessed hole is formed on the end face of the output shaft of the resistance device 20 near the one-way bearing 60. When the resistance device 20 is installed in the one-way bearing 60, the recessed hole on the output shaft of the resistance device 20 is aligned with the second through hole 65. Specifically, the recessed hole on the resistance device 20 in this embodiment is formed by a through-hole, consisting of a tapered hole, a cylindrical hole, and a frustum-shaped hole arranged from the outside to the inside. This facilitates the machining of the output shaft of the resistance device 20.

[0035] When the tension component 30 is in the resistance training state, it drives the one-way bearing 60 to rotate. If the pulling force of the tension component 30 is less than the rated output resistance of the drive motor 10, the tension component 30 only needs to overcome the resistance provided by the drive motor 10. If the pulling force of the tension component 30 is not less than the rated output resistance of the drive motor 10, then the resistance device 20 and the drive motor 10 jointly provide dual resistance. When the tension component 30 is in the tension recovery state, the drive motor 10 drives the one-way bearing 60 to move in the opposite direction, thus providing a recovery force.

[0036] It should be noted that when the tension assembly 30 is in the resistance training state, the tension assembly 30 is pulled away from the drive motor 10. At this time, the needle rollers of the one-way bearing 60 and the output shaft of the resistance device 20 automatically lock together to transmit torque, thus making the resistance device 20 connected to the one-way bearing 60. When the tension assembly 30 is in the tension recovery state, the tension assembly 30 rotates towards the drive motor 10, and the one-way bearing 60 and the resistance device 20 disengage from the self-locking state.

[0037] Regarding the resistance device 20 in this scheme:

[0038] In some embodiments, the resistance device 20 is any one of a mechanical resistance device, an electromagnetic resistance device, or a fluid resistance device. When the resistance device 20 is a mechanical resistance device, it can be any one of a frictional resistance device, a counterweight resistance device, or an inertial resistance device; when the resistance device 20 is an electromagnetic resistance device, it can be any one of a magnetically controlled resistance device or an electromagnetic eddy current resistance device.

[0039] In this embodiment, the resistance device 20 is selected as an electromagnetic resistance device based on the principle of magnetic powder damping. The resistance device 20 includes a movement shaft, a movement disc located in the middle section of the movement shaft, a first body and a second body rotatably connected to the movement shaft, and an inertia wheel rotatably connected to the movement shaft coaxially. The first body and the second body are respectively located on both sides of the movement disc and are joined together by a sealing ring to form a sealed cavity. Magnetic powder is provided in the sealed cavity, and the movement disc is located in the sealed cavity. A coil frame for coil mounting is provided outside the sealed cavity. The coil is mounted on the coil frame, and a third body for sealing the coil is provided on the coil frame. The third body is detachably connected to the first body and the second body. The structure of this resistance device is not the key technical point of this patent improvement, but rather borrows from the multi-purpose digital resistance device designed in CN114307038A.

[0040] Regarding the drive motor 10 in this solution:

[0041] The drive motor 10 of this solution includes a motor body 12 and a motor output shaft 11 connected to the motor body 12, wherein the motor output shaft 11 is connected to a one-way bearing 60. Since the one-way bearing 60 is connected to the tension assembly 30 through the transmission assembly 40, the drive motor 10 can drive the tension assembly 30 to rotate through the one-way bearing 60 and the transmission assembly 40. At this time, the motor torque of the drive motor 10 is transmitted to the tension assembly 30.

[0042] In this design, the drive motor 10 continuously generates motor torque that drives the tension component 30 to rotate in the direction of tension recovery. When the tension component 10 rotates in the resistance training direction, which is opposite to the direction of tension recovery, the tension component 10 needs to overcome the resistance generated by the motor torque of the drive motor 10. When the tension of the tension component 10 is greater than the rated resistance of the drive motor 10, the one-way bearing 60 is driven to rotate to connect with the resistance device 20. At this time, the resistance device 20 also provides additional resistance through the one-way bearing 60. When no external force is applied to the tension component 30, the tension component 30 will rotate in the direction of tension recovery because the drive motor 10 continuously generates motor torque that drives the tension component 30 to rotate in the direction of tension recovery.

[0043] Regarding the tension component 30 in this solution:

[0044] The tension assembly 30 includes a rotating shaft 33, a take-up coil 32 rigidly connected to the rotating shaft 33, and a pull rope 31 wound around the take-up coil 33. One end of the pull rope 31 is fixed to the take-up coil 32, and a driven pulley 34 is provided on the side of the take-up coil 32.

[0045] In some embodiments, the cable retractor 32 is provided with a cable retractor fixing hole, one end of the cable retractor 32 is fixed in the cable retractor fixing hole, and the other end is directly connected to the trainee or connected to other fitness equipment.

[0046] When an external force is applied to the pull rope 31 to pull it outward, the pull rope 31 drives the take-up device 32 to rotate in the direction of resistance training. At this time, the pull rope 31 needs to overcome the motor torque of the drive motor 10. When the tension of the pull rope 31 is greater than the additional resistance of the drive motor 10, the transmission assembly 40 drives the one-way bearing 60 to move towards the resistance device 20 to connect with the resistance device. The resistance device 20 and the drive motor 10 provide dual resistance. When it is necessary to retract the pull rope 31, the drive motor 10 actively provides a retraction force to drive the pull assembly 30 to rotate in the direction of pull retraction through the transmission assembly 40.

[0047] Regarding the transmission component 40 in this solution:

[0048] In this scheme, the transmission component 40 is a belt with its two ends respectively sleeved on the tension component 30 and the one-way bearing 60. Specifically, the two ends of the transmission component 40 are respectively sleeved on the driven pulley 34 and the one-way bearing 60, so that the rotation of the driven pulley 34 drives the rotation of the one-way bearing 60, and the rotation of the one-way bearing 60 can also drive the driven pulley 34 to rotate in the opposite direction.

[0049] This solution utilizes a belt-driven tension component 30 and a one-way bearing 60. Compared to other transmission methods, the belt better adapts to the dynamic load characteristics of fitness equipment and works efficiently in conjunction with the one-way bearing and resistance device. Compared to directly threading the tension component 30 onto the one-way bearing 60, this method offers flexible transmission and adjustable speed ratios, better adapting to complex working conditions. Specifically, the belt's elasticity can buffer the impact load generated by sudden force applied by the user (such as the instantaneous explosive force when rowing a boat), and the rotational speed of the one-way bearing 60 can be increased by changing the pulley diameter, thereby amplifying the response speed of the resistance device 20.

[0050] In some embodiments, one end of the tension component 30 is fixed to the resistance component 20 by a fixing bracket.

[0051] In addition, to protect the one-way bearing 60 and the drive motor 10, the hybrid fitness equipment of this solution also includes a motor housing 50, which is fitted over the one-way bearing 60 and the drive motor 10 for protection.

[0052] In summary, the hybrid fitness equipment provided by this solution uses a one-way bearing 60 to drive the motor 10 and the resistance device 20 in coordination, achieving dynamic switching between resistance training and pull recovery at a low cost. This hybrid fitness equipment utilizes the mechanical logic of the one-way bearing 60 and the flexible buffering characteristics of the belt drive to avoid complex electrical control and transmission structures. Compared with traditional solutions, it reduces the number of parts and controls costs through standardized components (such as one-way bearings and belts). While providing intelligent recovery force function, it achieves the effect of reducing equipment cost compared with similar products, thus combining economy and functionality.

[0053] Example 2

[0054] This solution further provides an optimized hybrid power fitness device based on Embodiment 1. The hybrid power fitness device provided in Embodiment 2 additionally includes:

[0055] The clutch assembly 70 includes a clutch 71 and a secondary drive pulley 72. The clutch 71 is movably disposed between the secondary drive pulley 72 and the tension assembly 30 to switch between a first engagement position and a second position. When the clutch 71 is in the first engagement position, the clutch 71 is engaged with the tension assembly 30. When the clutch 71 is in the second engagement position, the clutch 71 is engaged with the secondary drive pulley 72.

[0056] The hybrid fitness equipment in this second embodiment is equivalent to adding a clutch component 70 to the first embodiment. The clutch component 70 allows the hybrid fitness equipment to be connected to other fitness equipment to provide hybrid power to other fitness equipment. The contents of this second embodiment that are the same as those in the first embodiment will not be described in detail here.

[0057] Additionally, it should be noted that when the clutch 71 is in the first engagement position, and when the tension assembly 30 is in the resistance training state, the resistance device 20 and the drive motor 10 are connected to the one-way bearing 60 for transmission; when the tension assembly 30 is in the tension recovery state, the drive motor 10 is connected to the one-way bearing 60 to provide recovery force for the tension assembly 30.

[0058] When the clutch 72 is in the second engagement position, and when the secondary drive pulley 72 is in the resistance training state, the resistance device 20 and the drive motor 10 are both connected to the one-way bearing 60 for transmission. When the secondary drive pulley 72 is in the tension recovery state, the drive motor 10 is connected to the one-way bearing to provide recovery force to the tension assembly 30.

[0059] Furthermore, when the secondary active pulley 72 is in the resistance training state, it drives the one-way bearing 60 to rotate. If the tension of the secondary active pulley 72 is less than the rated output resistance of the drive motor 10, the secondary active pulley 72 only needs to overcome the resistance provided by the drive motor 10. However, if the tension of the secondary active pulley 72 is not less than the rated output resistance of the drive motor 10, then the resistance device 20 and the drive motor 10 jointly provide dual resistance. When the secondary active pulley 72 is in the tension recovery state, the drive motor 10 drives the one-way bearing 60 to move in the opposite direction, thus providing recovery force. This scheme defines the rotation of the tension component 30 or the secondary active pulley 72 in the resistance training direction as the "resistance training state," and the rotation of the tension component 30 or the secondary active pulley 72 in the tension recovery direction as the "tension recovery state."

[0060] Regarding the clutch assembly 70 in this solution:

[0061] This solution uses an additional clutch assembly 70 to switch the training subject of the hybrid fitness equipment. As mentioned earlier, when the clutch 71 is in the first engagement position, the tension assembly is still the training subject; while when the clutch 72 is in the second engagement position, other peripheral fitness equipment connected to the secondary drive pulley 72 is the training subject. The peripheral fitness equipment can be a treadmill, a fly station, etc. This solution does not impose any special restrictions on the peripheral fitness equipment.

[0062] In some embodiments, the secondary drive pulley 72 is connected to the peripheral fitness equipment via belt drive or other transmission methods.

[0063] like Figure 6 and Figure 7 As shown, the clutch assembly 70 is also mounted on the same shaft 33 of the tension assembly 30, so that when the clutch 71 is in the second engagement state, the rotational force on the shaft 33 can still be transmitted to the secondary drive pulley 72.

[0064] In some embodiments, the clutch 71 is movably disposed between the secondary drive pulley 72 and the tension assembly 30 via a moving device to switch positions between a first engagement position and a second position.

[0065] In some embodiments, the moving device is a pull pin, a shift fork, or a knob. When the moving device is a pull pin, a pin is provided on the clutch 71, and the clutch is inserted into positioning holes at different positions through the pin to achieve switching between the first engagement position and the second engagement position; when the moving device is a shift fork, the shift fork is connected to the clutch 71, and under the drive of the drive mechanism, the shift fork can move linearly along the guide rod to drive the clutch 71 to switch between the first engagement position and the second engagement position.

[0066] To achieve stable engagement between the clutch 71 and the tension assembly 30 or the secondary drive pulley 72, the transmission assembly 30 is provided with a first fixed keyway on the side near the clutch 71, and the clutch 71 is also provided with a first keyway matching the first fixed keyway on the side near the transmission clutch 71. When the clutch 71 is in the first engagement position, the clutch 71 and the transmission assembly 30 are connected by radial keyways. The secondary drive pulley 72 is provided with a second fixed keyway on the side near the clutch 71, and the clutch 71 is also provided with a second keyway matching the second fixed keyway on the side near the transmission secondary drive pulley 72. When the clutch 71 is in the second engagement position, the clutch 71 and the secondary drive pulley 72 are connected by radial keyways.

[0067] In some embodiments, the clutch 71 includes, but is not limited to, any form of clutch device such as electromagnetic or mechanical.

[0068] In some embodiments, the hybrid fitness equipment further includes a connecting frame 80, wherein the connecting frame 80 includes a frame body 81 with one end fixed to the side of the drive motor 10 or the resistance device 20 and the other end sleeved on the side of the clutch assembly 70. This design uses the connecting frame 80 to limit the clutch assembly 70 and protect the entire hybrid fitness equipment.

[0069] In some embodiments, one end of the frame 81 is fixed to the side of the drive motor 10 or the resistance device 20 by a nut, and the other end is sleeved on the rotating shaft 33 by a connector 82. The connector 82 is located on the side of the clutch assembly 70 to limit and fix the secondary drive pulley 72. Since the connector 82 is sleeved on the rotating shaft 33, the setting of the connecting frame 80 will not affect the normal rotation of the rotating shaft 33.

[0070] In other embodiments, the hybrid fitness equipment of this solution additionally includes a transmission adjustment component 90, which cooperates with the transmission component 40 to adjust the transmission component 40.

[0071] In this design, the transmission component 40 is a belt, so the transmission adjustment component 90 mainly functions to adjust the belt tension.

[0072] like Figure 7As shown, the transmission adjustment assembly 90 of this solution includes a transmission connecting frame 92 fixed to one side of the transmission assembly 40 and a transmission wheel 91 movably connected to the transmission connecting frame 92, wherein the transmission assembly 40 is pressed against by the transmission wheel 91. Specifically, the transmission assembly 40 is a belt, with both ends of the belt respectively fitted onto the surfaces of the driven pulley 34 of the tension assembly 30 and the one-way bearing 60, and the belt is positioned via the transmission wheel 91 to adjust the belt tension. When the transmission wheel 91 presses towards the belt, the belt becomes tighter, and when the transmission wheel 91 moves away from the belt, the belt becomes looser.

[0073] In some embodiments, the transmission connecting frame 92 has a protruding transmission wheel fixing member on the inner side of the relative transmission assembly 40, and the transmission wheel 92 is rotatably mounted on the transmission wheel fixing member by a rotating member to realize the adjustment of the position of the transmission wheel 92.

[0074] In some embodiments, one end of the transmission connecting bracket 92 is fixed to the side of the tension assembly 30, and the other end is connected to the motor housing 50.

[0075] It should be noted that the hybrid fitness equipment in Embodiment 1 may also be equipped with a transmission adjustment component 90, the specific structure of which can be seen from the description above.

[0076] As described above, the hybrid fitness equipment of this embodiment adds a clutch component to the first embodiment. The clutch can switch the engagement position between the tension component and the secondary active pulley, thereby switching the training subject and expanding the compatibility of the equipment with peripheral fitness equipment (such as treadmills, fly stations, etc.). At the same time, the belt tension can be flexibly adjusted through the transmission adjustment component. This hybrid fitness equipment simplifies the structure and reduces costs by utilizing mechanical logic and flexible transmission characteristics, and combines economy and functionality.

[0077] Those skilled in the art should understand that the technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
