Abstract
Description
Technical Field
[0001] The present invention relates to the field of fitness equipment, and in particular to hybrid power fitness equipment. Background Art
[0002] The resistance training components of fitness equipment are the core components for achieving strength training. They enhance muscle strength, endurance and explosive power by applying mechanical resistance. The resistance training components of common fitness equipment on the market include magnetic control 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 defect of only providing one-way resistance and being unable to achieve recovery force adjustment - they only provide load in the force-generating phase, and trainees need to rely entirely on their own strength to overcome inertia during the return process. This causes trainees to rely entirely on their own strength to overcome inertia during the return process, resulting in decreased movement continuity and reduced exercise efficiency.
[0003] Especially in home and female fitness scenarios, the defects of fitness equipment that cannot provide recovery force adjustment are more prominent: on the one hand, the diverse training needs of trainees (such as buffering assistance for rehabilitation training and bidirectional force feedback for body shaping exercises) cannot be met, and the trainees' joints are prone to damage due to the lack of recovery force buffering; on the other hand, traditional equipment with bidirectional force adjustment relies on complex mechanical structures (such as dual motors, hydraulic energy storage devices), resulting in a surge in the cost of the entire machine and a large size, which makes it difficult to adapt to the lightweight needs of home space and the dual demands of female users for economy and operation-friendliness.
[0004] In summary, there is an urgent need on the market to design a low-cost fitness device that has both recovery and resistance functions, especially in the fields of smart home fitness equipment and women-specific equipment. Summary of the Invention
[0005] The purpose of the present invention is to provide a hybrid fitness equipment that uses a resistance device and a drive motor to provide recovery force and resistance at a low cost, thereby solving the experience bottleneck of unidirectional resistance in the resistance training components of the prior art and the cost contradiction of traditional bidirectional force equipment.
[0006] To achieve the above objectives, the present technical solution provides a hybrid fitness equipment, including: a tension component; a driving motor and a resistance device matched through a one-way bearing; the tension component is connected to the one-way bearing through a transmission component, when the tension component is in a first resistance training state, the resistance device and the driving motor are both connected to the one-way bearing, and the resistance device provides resistance for the tension resistance; when the tension component is in a second resistance training state, the resistance device and the driving motor are both connected to the one-way bearing, and the resistance device and the driving motor jointly provide resistance for the tension component; when the tension component is in a tension recovery state, the driving motor is connected to the one-way bearing to provide a recovery force for the tension component; wherein the tension component is defined as being in the first resistance training state when it is pulled in a direction away from the driving motor and the tension of the tension component is less than the rated resistance of the driving motor; the tension component is defined as being in the second resistance training state when it is pulled in a direction away from the driving motor and the tension of the tension component is not less than the rated resistance of the driving motor; and the tension component is defined as being in the tension recovery state when it moves in a direction close to the driving motor.
[0007] Compared with the existing technology, this technical solution has the following characteristics and beneficial effects: This solution utilizes the unidirectional transmission characteristics of one-way bearings to automatically connect and disconnect the drive motor and resistance device without the need for additional sensors or electronic control systems. During resistance training, the one-way bearing drives both to provide resistance. During force recovery, the one-way bearing automatically disengages from the resistance device, leaving only the drive motor operating. This provides hybrid fitness equipment for the fitness industry. Compared to traditional hybrid equipment that relies on electronic control systems, this solution simplifies control logic through mechanical structure and utilizes standardized components such as one-way bearings and belts, reducing hardware costs and maintenance. Furthermore, the transmission component of this solution utilizes a belt drive, leveraging its elasticity to cushion sudden user force, avoiding vibration, noise, or damage caused by rigid transmission, extending equipment life, and improving exercise comfort. Furthermore, by changing the pulley diameter, the transmission ratio can be flexibly adjusted, amplifying the resistance device's response speed or driving torque, making it suitable for complex working conditions such as strength training or high-frequency, rapid training.
[0008] In another embodiment, this solution incorporates an additional clutch assembly, allowing the clutch to switch the engagement position 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 mode); in the second engagement position, the secondary drive pulley quickly connects to peripheral devices such as a treadmill and a fly station, providing hybrid power for a variety of fitness equipment, achieving "one machine for multiple uses." This eliminates the need for an additional power source, reduces the cost of purchasing multiple devices, and expands the device's usage scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention are within the scope of protection of the present invention.

Therefore, the above terms should not be understood as limiting the present invention.
[0019] Example 1 like Figure 1 As shown, this solution provides a hybrid fitness equipment, including: Tension component 30; The drive motor 10 and the resistance device 20 are matched through a one-way bearing 60; The tension component 30 is connected to the one-way bearing 60 through the transmission component 40. When the tension component 30 is in the first resistance training state, the resistance device 20 and the drive motor 20 are both connected to the one-way bearing 60, and the resistance device 20 provides resistance for the tension resistance 30; when the tension component 30 is in the second resistance training state, the resistance device 20 and the drive motor 20 are both connected to the one-way bearing 60, and the resistance device 10 and the drive motor 20 jointly provide resistance for the tension component 30; when the tension component 30 is in the tension recovery state, the drive motor 20 is connected to the one-way bearing 60. The motor 10 is connected to the one-way bearing 60 to provide a recovery force for the tension component 30; the tension component 30 is defined as being in a first resistance training state when it is pulled in a direction away from the drive motor 10 and the tension of the tension component 30 is less than the rated resistance of the drive motor 10; the tension component 30 is defined as being in a second resistance training state when it is pulled in a direction away from the drive motor 10 and the tension of the tension component 30 is not less than the rated resistance of the drive motor 10; the tension component 30 is defined as being in a tension recovery state when it moves in a direction close to the drive motor 10.
[0020] This solution uses a one-way bearing 60 to coordinate the drive motor 10 and the resistance device 10, achieving dynamic switching between resistance training and tension recovery without adding excessive additional costs, so as to provide the fitness field with hybrid fitness equipment that can generate recovery force.
[0021] About the one-way bearing 60 of this solution: The resistance device 20 and the drive motor 10 are respectively located at the two ends of the one-way bearing 60, wherein one end of the one-way bearing 60 is transmission-connected to the motor output shaft 11 of the drive motor 10, and the other end is cooperatively connected to the resistance device 20, and the tension component 30 is sleeved on the outside of the one-way bearing 60 through the transmission component 40.
[0022] Specifically, such as Figure 4 As shown, the one-way bearing 60 of this scheme includes an integrally formed resistance device connecting section 61, a transmission component connecting section 62 and a motor connecting section 63, wherein the interior of the motor connecting section 63 is 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.
[0023] 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 assembly connecting section 62 and the motor connecting section 63, wherein the first through hole 64 is connected to the second through hole 65 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 in the second through hole 65, and the output shaft of the resistance device 20 is placed in the first through hole 64.
[0024] In some embodiments, the outer surface of the motor output shaft 11 is designed with an external thread, and the inner side of the motor connecting section 63 is provided with an internal thread. The motor output shaft 11 and the motor connecting section 62 are connected by threaded fitting, and the motor output shaft 11 of the drive motor 10 passes through the second through hole 65 to be connected to the one-way bearing 60.
[0025] In some embodiments, the second through hole 65 is designed to be an incomplete 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 to prevent slipping.
[0026] 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.
[0027] In some embodiments, a recessed hole is formed on the output shaft of the resistance device 20 near the end surface of 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 arranged opposite the second through hole 65. Specifically, the recessed hole on the resistance device 20 of this embodiment is formed by a conical hole, a cylindrical hole, and a frustum hole arranged from the outside to the inside. This has the advantage of facilitating the processing of the output shaft of the resistance device 20.
[0028] When the tension assembly 30 is in the first resistance training state, the tension assembly 30 drives the one-way bearing 60 to rotate. If the pulling force of the tension assembly 30 is less than the rated output resistance of the drive motor 10, the tension assembly 30 only needs to overcome the resistance provided by the drive motor 10. If the pulling force of the tension assembly 30 is not less than the rated output resistance of the drive motor 10, the resistance device 20 and the drive motor 10 jointly provide dual resistance. When the tension assembly 30 is in the tension recovery state, the drive motor 10 drives the one-way bearing 60 to move in the opposite direction, thereby providing the recovery force.
[0029] It should be noted that when the tension component 30 is in the first resistance training state or the second resistance training state, the tension component 30 is pulled in the direction away from the drive motor 10. At this time, the needle roller of the one-way bearing 60 and the output shaft of the resistance device 20 automatically lock and transmit torque, so that the resistance device 20 is transmission-connected with the one-way bearing 60; and when the tension component 30 is in the tension recovery state, when the tension component 30 rotates in the direction close to the drive motor 10, the one-way bearing 60 and the resistance device 20 are out of the self-locking state.
[0030] About the resistance device 20 of this scheme: 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, the resistance device 20 can be any one of a friction resistance device, a counterweight resistance device, and an inertial resistance device; when the resistance device 20 is an electromagnetic resistance device, the resistance device 20 can be any one of a magnetic control resistance device and an electromagnetic eddy current resistance device.
[0031] In an embodiment of the present scheme, the resistance device 20 of the present scheme is selected as an electromagnetic resistance device based on the principle of magnetic powder damping, and the resistance device 20 includes a movement shaft, a movement disc arranged 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; the first body and the second body are respectively arranged on both sides of the movement disc, and are merged 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 installation is provided outside the sealed cavity, the coil is installed on the coil frame, and a third body for enclosing the coil is provided on the coil frame, and the third body is detachably connected to the first body and the second body respectively. The structure of the resistance device is not the technical point of the improvement of this patent, but a multi-purpose digital resistance device designed by CN114307038A.
[0032] Regarding the drive motor 10 of this solution: The drive motor 10 of this embodiment includes a motor body 12 and a motor output shaft 11 connected to the motor body 12. The motor output shaft 11 is in transmission connection with a one-way bearing 60. Since the one-way bearing 60 is in transmission connection with the tension assembly 30 via the transmission assembly 40, the drive motor 10 can drive the tension assembly 30 to rotate via 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.
[0033] The drive motor 10 of this solution continuously generates motor torque that drives the tension assembly 30 to rotate in the tension recovery direction. When the tension assembly 10 rotates in the resistance training direction opposite to the tension recovery direction, the tension assembly 10 needs to overcome the resistance generated by the motor torque of the drive motor 10. When the tension of the tension assembly 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 acts on the tension assembly 30, the tension assembly 30 will rotate in the tension recovery direction because the drive motor 10 continuously generates motor torque that drives the tension assembly 30 to rotate in the tension recovery direction.
[0034] Regarding the tension component 30 of this solution: The tension assembly 30 includes a rotating shaft 33, a wire take-up device 32 rigidly connected to the rotating shaft 33, and a pull rope 31 wound around the wire take-up device 33. One end of the pull rope 31 is fixed to the wire take-up device 32, and a driven pulley 34 is provided on the side of the wire take-up device 32.
[0035] In some embodiments, a cable reel 32 is provided with a cable reel fixing hole, one end of the cable reel 32 is fixed in the cable reel fixing hole, and the other end is directly connected to the trainee or connected to other fitness equipment.
[0036] When an external force acts on the pull rope 31 to pull the pull rope 31 outward, the pull rope 31 drives the cable take-up device 32 to rotate in the resistance training direction under the action of the external force. At this time, the pull rope 31 needs to overcome the motor torque of the drive motor 10. When the pulling force of the pull rope 31 is greater than the additional resistance of the drive motor 10, the one-way bearing 60 is driven by the transmission assembly 40 to move toward the resistance device 20 to connect to the resistance device, and the resistance device 20 and the drive motor 10 provide dual resistance. When the pull rope 31 needs to be recovered, the drive motor 10 actively provides a recovery force to drive the tension assembly 30 to rotate in the tension recovery direction through the transmission assembly 40.
[0037] Regarding the transmission component 40 of this solution: The transmission component 40 of this solution is a belt with its two ends respectively mounted on the tension component 30 and the one-way bearing 60. Specifically, the two ends of the transmission component 40 are respectively mounted 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 reverse rotation of the driven pulley 34 can also be driven by the reverse rotation of the one-way bearing 60.
[0038] This solution uses a belt to transmit the tension component 30 and the one-way bearing 60. Compared to other transmission methods, the belt can better adapt to the dynamic load characteristics of the fitness equipment and form a highly efficient synergy with the one-way bearing and the resistance device. Compared to the method of directly threading the tension component 30 onto the one-way bearing 60, it has flexible transmission and adjustable speed ratio, which can better adapt to complex working conditions. Specifically, the elasticity of the belt can buffer the impact load generated by the user's sudden application of force (such as the instantaneous explosive force when pulling the oars on a rowing machine), and the 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.
[0039] In some embodiments, one end of the tension component 30 is fixed to the resistance component 20 via a fixing bracket.
[0040] In addition, in order to protect the one-way bearing 60 and the drive motor 10, the hybrid fitness equipment of this solution further includes a motor housing 50, which is placed outside the one-way bearing 60 and the drive motor 10 to play a protective role.
[0041] In summary, the hybrid fitness equipment provided by this solution uses the one-way bearing 60 to coordinate the drive motor 10 and the resistance device 20, thereby realizing dynamic switching between resistance training and tension recovery at a low cost. The hybrid fitness equipment uses the mechanical logic of the one-way bearing 60 and the flexible buffering characteristics of the belt drive to avoid complex electronic control and transmission structures, reducing the number of parts compared to traditional solutions, and controlling costs through standardized components (such as one-way bearings and belts). While providing intelligent recovery force functions, the equipment cost is reduced compared to similar products, achieving both economy and functionality.
[0042] Example 2 This solution further provides a hybrid power fitness device with an optimized design based on the first embodiment. The hybrid power fitness device provided in the second embodiment additionally includes: The clutch assembly 70 includes a clutch 71 and a secondary driving pulley 72. The clutch 71 is movably arranged between the secondary driving 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 and connected with the tension assembly 30. When the clutch 71 is in the second engagement position, the clutch 71 is engaged and connected with the secondary driving pulley 72.
[0043] The hybrid fitness device of the second embodiment is equivalent to the first embodiment in that a clutch assembly 70 is additionally added. Through the configuration of the clutch assembly 70, the hybrid fitness device can be connected to other fitness devices to provide hybrid power for the other fitness devices. The contents of the second embodiment that are the same as those of the first embodiment will not be introduced here in detail.
[0044] In addition, it should be noted that when the clutch 71 is in the first engaged position, when the tension component 30 is in the first resistance training state or the second resistance training state, the resistance device 20 and the drive motor 10 are transmission-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.
[0045] When the clutch 72 is in the second meshing position, when the secondary active pulley 72 is in the first resistance training state, the resistance device 20 and the drive motor 10 are both connected to the one-way bearing 60, and the resistance device 20 provides resistance for the secondary active pulley 72; when the secondary active pulley 72 is in the second resistance training state, the resistance device 20 and the drive motor 10 are both connected to the one-way bearing 60, and the resistance device 20 and the drive motor 20 jointly provide resistance for the secondary active pulley 72; the state in which the secondary active pulley 72 rotates in the resistance training direction and the tension of the secondary active pulley 72 is less than the rated resistance of the drive motor 10 is defined as the first resistance training state, and the state in which the secondary active pulley 72 rotates in the resistance training direction and the tension of the secondary active pulley 72 is not less than the rated resistance of the drive motor 10 is defined as the second resistance training state; the state in which the secondary active pulley 72 rotates in the tension recovery direction is the tension recovery state.
[0046] Regarding the clutch assembly 70 of this solution: This solution uses an additional clutch assembly 70 to switch the training subject of the hybrid fitness equipment. As mentioned above, when the clutch 71 is in the first engaged position, the tension assembly is still the training subject; and when the clutch 72 is in the second engaged position, other peripheral fitness equipment connected by the secondary active pulley 72 serves as the training subject. The peripheral fitness equipment is a treadmill, a fly station, etc. This solution does not impose any special restrictions on the peripheral fitness equipment.
[0047] In some embodiments, the secondary active pulley 72 is connected to the peripheral fitness equipment via a belt drive or other transmission methods.
[0048] like Figure 6 and Figure 7As shown, the clutch assembly 70 is also sleeved on the same rotating shaft 33 of the tension assembly 30 , so that when the clutch 71 is in the second engaged state, the rotational force on the rotating shaft 33 can still be transmitted to the secondary driving pulley 72 .
[0049] In some embodiments, the clutch 71 is movably disposed between the secondary driving pulley 72 and the tension assembly 30 via a moving device to switch positions between a first engaged position and a second position.
[0050] 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 a positioning hole at different positions through the pin to achieve switching between the first engaged position and the second engaged position. When the moving device is a shift fork, the shift fork is connected to the clutch 71, and driven by the driving mechanism, the shift fork can move linearly along the guide rod to drive the clutch 71 to switch between the first engaged position and the second engaged position.
[0051] In order to achieve stable engagement of the clutch 71 with the tension component 30 or the secondary driving pulley 72, a first fixed key groove is provided on the side of the transmission component 30 close to the clutch 71, and a first key groove matching the first fixed key groove is also provided on the side of the clutch 71 close to the transmission clutch 71. When the clutch 71 is in the first engaged position, the clutch 71 and the transmission component 30 are connected by radial key grooves; a second fixed key groove is provided on the side of the secondary driving pulley 72 close to the clutch 71, and a second key groove matching the second fixed key groove is also provided on the side of the clutch 71 close to the transmission secondary driving pulley 72. When the clutch 71 is in the second engaged position, the clutch 71 and the secondary driving pulley 72 are connected by radial key grooves.
[0052] In some embodiments, the clutch 71 includes any type of clutch device including but not limited to electromagnetic, mechanical, etc.
[0053] In some embodiments, the hybrid fitness device further includes a connecting frame 80, wherein the connecting frame 80 comprises a frame body 81 with one end secured to the side of the drive motor 10 or resistance device 20 and the other end positioned around the side of the clutch assembly 70. In this embodiment, the connecting frame 80 serves to limit the clutch assembly 70 and protect the entire hybrid fitness device.
[0054] 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 through a connecting member 82, and the connecting member 82 is located on the side of the clutch assembly 70 to limit and fix the secondary driving pulley 72. Since the connecting member 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.
[0055] 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 .
[0056] The transmission component 40 of this solution is a belt, so the transmission adjustment component 90 mainly plays the role of adjusting the tightness of the belt.
[0057] like Figure 7 As shown, the transmission adjustment assembly 90 of this embodiment 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 by the transmission wheel 91. Specifically, the transmission assembly 40 is a belt, and the two ends of the belt are respectively sleeved on the driven pulley 34 of the tension assembly 30 and the surface of the one-way bearing 60, and the belt is arranged through the transmission wheel 91 so that the tightness of the belt can be adjusted by the transmission wheel 91. When the transmission wheel 91 is pressed in the direction close to the belt, the belt becomes tighter, and when the transmission wheel 91 moves in the direction away from the belt, the belt becomes looser.
[0058] In some embodiments, a protruding transmission wheel fixing member is provided on the inner side of the transmission connecting frame 92 relative to the transmission assembly 40, and the transmission wheel 92 is rotatably set on the transmission wheel fixing member through a rotating member to achieve adjustment of the position of the transmission wheel 92.
[0059] In some embodiments, one end of the transmission connecting frame 92 is fixed to a side of the tension assembly 30 , and the other end is connected to the motor housing 50 .
[0060] It should be noted that the hybrid fitness equipment of the first embodiment may also be provided with a transmission adjustment assembly 90 , the specific structure of which can be seen from the above description.
[0061] As described above, the hybrid fitness equipment of the second embodiment adds a clutch component on the basis of the first embodiment. The clutch can switch the engagement position between the tension component and the secondary active pulley, thereby switching the training subject, expanding the compatibility of the equipment with peripheral fitness equipment (such as treadmills, bird stations, etc.). At the same time, the belt tightness can be flexibly adjusted through the transmission adjustment component. The hybrid fitness equipment uses mechanical logic and flexible transmission characteristics to simplify the structure, reduce costs, and has both economy and functionality.
[0062] Those skilled in the art should understand that the technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are 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.
[0063] The above embodiments merely illustrate several embodiments of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
