Description

Technical Field

[0001] This invention relates to the field of sports training equipment technology, and in particular to a gear shifting drive device and a comprehensive training apparatus. Background Technology

[0002] As living standards and quality of life improve year by year, people are paying more and more attention to their health. Physical exercise is one of the most effective and cost-efficient ways to achieve a healthy and strong physique. Nowadays, more and more people are participating in more comprehensive physical activities, and integrated training equipment that combines aerobic and anaerobic training is gaining popularity. Among these, the most common integrated training equipment combines a strength training machine with a treadmill.

[0003] However, existing comprehensive training equipment usually requires two motors. One motor is used as the resistance source for the strength training machine, and the other motor is used as the power source for the treadmill. This not only increases the number of motors used and raises the cost, but also makes the overall structure of the comprehensive training equipment more complex, difficult to control, less miniaturized, and occupies more space. Summary of the Invention

[0004] Therefore, it is necessary to provide a gear shifting drive device and a comprehensive training device to solve the problems of high cost, complex structure, difficult control, and low miniaturization of existing technologies.

When the trainee wants to use the second training machine for training, the gear shift actuator can be operated again to drive the clutch to move along the other end of the power shaft. The clutch can then be driven to engage with the second actuating wheel, thereby applying the power generated by the rotation of the power shaft to the second training machine driven by the second actuating wheel, thus satisfying the requirement of the power component as a power source for the second training machine. In other words, compared with the prior art, the gear shifting drive device of this application can meet the power requirements of the first and second training machines by adjusting the clutch reversal by setting only one power component, thereby reducing the number of power components, simplifying the overall structure, reducing the control difficulty, and improving the miniaturization level of the whole machine.

Detailed Implementation

[0053] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0054] like Figure 1 As shown in the embodiment of this application, a comprehensive training device 100 is provided, which can meet the combined needs of trainees for aerobic and anaerobic training, enabling trainees to complete diverse training content on a single device.

[0055] For example, the integrated training device 100 includes: a first training machine, a second training machine, and a shift drive device 30. The first training machine is an anaerobic training machine, used for anaerobic training, and can be a strength training machine 10. The second training machine is an aerobic training machine, used for aerobic training, and can be a treadmill 20, a walking machine, etc. The following description uses a strength training machine 10 as the first training machine and a treadmill 20 as the second training machine as examples.

[0056] As is easily understood, the strength training machine 10 is used for trainees to perform strength training such as pull-ups, flat pulls, and high pushes, while the treadmill 20 meets the needs of trainees for running training.

[0057] Please continue reading. Figures 1 to 3 The strength training machine 10 is connected to the first actuating wheel 33 of the shift drive device 30; the treadmill 20 is connected to the second actuating wheel 34 of the shift drive device 30.

[0058] In this embodiment, the gear shift drive device 30 includes: a power component 31, a clutch 32, a first actuating wheel 33, a second actuating wheel 34, and a gear shift actuator 35.

[0059] The power assembly 31 includes a frame 311 and a power shaft 313 rotatably mounted on the frame 311. Furthermore, the power assembly 31 also includes a power source connected to the power shaft 313 and driving the power shaft 313 to rotate. For example, the power source can be a motor 312, which is fixed to the frame 311 by screws or other means and connected to the power shaft 313. The power shaft 313 is driven to rotate by the rotational power output from the motor 312. In other embodiments, the power source can also be an electromagnetic actuator, an engine, or other devices that can provide rotational power to the power shaft 313; these will not be elaborated further here.

[0060] The clutch 32 is mounted on the power shaft 313 and can rotate with the power shaft 313, and the clutch 32 can move axially along the power shaft 313. Specifically, the clutch 32 and the power shaft 313 are connected by a transmission guide structure, which is used to drive the clutch 32 to rotate via the power shaft 313 and to allow the clutch 32 to move axially along the power shaft 313. The transmission guide structure can be a key-groove fit structure, a pulley-rail fit structure, or a ball-rail fit structure. For example, when the transmission guide structure is a key-groove fit structure, the clutch 32 and the power shaft 313 are connected by a key. The clutch 32 has an axially penetrating through hole in its middle, the hole wall has a keyway, and a key protrudes from the middle section of the power shaft 313. The clutch 32 is mounted on the drive shaft 313 and is circumferentially fixed by key and keyway connection, allowing the drive shaft 313 to drive the clutch 32 to rotate synchronously and satisfying the requirement that the clutch 32 can move axially back and forth on the drive shaft 313. When the transmission guide structure is a pulley-rail fit structure or a ball-rail fit structure, the rail is set on the drive shaft 313, and the clutch 32 is equipped with pulleys or balls. The clutch 32 and the drive shaft 313 are circumferentially fixed by the pulley-rail fit or the ball-rail fit, allowing the drive shaft 313 to drive the clutch 32 to rotate synchronously and satisfying the requirement that the clutch 32 can move axially back and forth on the drive shaft 313.

[0061] The first actuating wheel 33 is rotatably mounted on the power shaft 313 and located on one axial side of the clutch 32. The first actuating wheel 33 is used for transmission engagement with the strength training machine 10. Specifically, the first actuating wheel 33 is rotatably connected to the power shaft 313, such as through a bearing. A retaining ring is provided at the axial end of the first actuating wheel 33 to axially limit its sliding along the power shaft 313. The second actuating wheel 34 is rotatably mounted on the power shaft 313 and located on the other axial side of the clutch 32. The second actuating wheel 34 is used for transmission engagement with the treadmill 20. Similarly, the second actuating wheel 34 is rotatably connected to the power shaft 313, such as through a bearing. A retaining ring is provided at the axial end of the second actuating wheel 34 to axially limit its sliding along the power shaft 313. The axial direction of the clutch 32 is parallel to the axial direction of the power shaft 313. The shifting actuator 35 is mounted on the frame 311 and drives the clutch 32. The shifting actuator 35 drives the clutch 32 to move axially along the power shaft 313 so that the clutch 32 is driven to connect with the first actuating wheel 33 or the second actuating wheel 34.

[0062] In one embodiment, the transmission guide structure is located in the middle of the power shaft 313, that is, the transmission guide structure is located between the first actuating wheel 33 and the second actuating wheel 34. In this way, the transmission guide structure can be used only to drive the clutch 32 to rotate and move the clutch 32 along the axial direction of the power shaft 313, without interfering with the rotational connection between the first actuating wheel 33 and the second actuating wheel 34 and the power shaft 313.

[0063] When a trainee needs to use the strength training machine 10 for anaerobic training, the trainee can operate the shifting actuator 35 of the shifting drive device 30. The shifting actuator 35 drives the clutch 32 to move along one end of the power shaft 313, and the clutch 32 can then be connected to the first actuating wheel 33. At this time, the power assembly 31 is started, and the power shaft 313 can drive the clutch 32 and the first actuating wheel 33 to rotate. Because the first actuating wheel 33 is connected to the strength training machine 10, it can provide the torque generated by the power assembly 31 to the strength training machine 10, thus satisfying the function of the power assembly 31 as the strength training machine 10. The resistance source is required; in addition, if the trainee wants to use the treadmill 20 for aerobic training, the shift actuator 35 can be operated again. The shift actuator 35 can drive the clutch 32 to move along the other end of the power shaft 313. The clutch 32 can then be connected to the second actuating wheel 34. At this time, the power component 31 is started, and the power shaft 313 can drive the clutch 32 and the second actuating wheel 34 to rotate. The second actuating wheel 34 can provide the power generated by the power component 31 to the treadmill 20 because it is connected to the treadmill 20, thus meeting the need of the power component 31 as the power source of the treadmill 20.

[0064] In other words, compared with the existing technology, the shift drive device 30 of this solution can meet the power requirements of the strength training machine 10 and the treadmill 20 by adjusting the reversing of the clutch 32. This reduces the number of power components 31, simplifies the overall structure, reduces costs and control difficulty, and improves the miniaturization level of the whole machine.

[0065] Please continue reading. Figure 1 , Figure 8 and Figure 9Furthermore, the strength training machine 10 includes a winding wheel 11, which is drivenly connected to the first actuating wheel 33 to achieve a transmission engagement between the first actuating wheel 33 and the strength training machine 10. The winding wheel 11 of the strength training machine 10 has a winding groove, and a pull rope 12 is wound inside the winding groove. One end of the pull rope 12 extending out of the winding groove is connected to a handle 13. Exemplarily, power transmission between the winding wheel 11 and the first actuating wheel 33 can be achieved through any one of the following methods: gear transmission, belt transmission, chain transmission, etc. Furthermore, the treadmill 20 includes a transmission wheel 21, a pulley 22, a front roller 23, and a running belt 25. The transmission wheel 21 is drivenly connected to the second actuating wheel 34 to achieve a transmission engagement between the second actuating wheel 34 and the treadmill 20. The drive wheel 21 of the treadmill 20 is coaxially connected to a pulley 22. A belt 24 is fitted onto the pulley 22 and the front roller 23 of the treadmill 20. The front roller 23 is used to drive the running belt 25 to rotate. Power can be transmitted between the drive wheel 21 and the second driving wheel 34 through any of the following methods: gear transmission, belt transmission, chain transmission, etc., so that the second driving wheel 34 drives the running belt 25 to rotate through the drive wheel 21, the pulley 22, and the front roller 23.

[0066] When a trainee wants to use the strength training machine 10 for strength training, the clutch 32 can be engaged with the first actuating wheel 33. At this time, the motor 312 drives the winding wheel 11 to rotate through the power shaft 313, the clutch 32, and the first actuating wheel 33, so as to apply resistance to the pull rope 12 and the handle 13, thereby enabling strength training. When a trainee wants to use the treadmill 20 for running exercise, the shifting actuator 35 drives the clutch 32 to move on the power shaft 313, so that the clutch 32 is disengaged from the first actuating wheel 33 and then engaged with the second actuating wheel 34. The motor 312 can then drive the transmission wheel 21 to rotate through the power shaft 313, the clutch 32, and the second actuating wheel 34, thereby driving the running belt 25 to rotate to meet the running needs. Compared to the existing technology where the strength training machine 10 and the treadmill 20 are each equipped with a separate motor 312, the shifting actuator 35 of this solution adjusts the clutch 32 to engage with the first actuating wheel 33 or the second actuating wheel 34, thereby driving the winding wheel 11 or the transmission wheel 21 to rotate. This provides a resistance source for the strength training machine 10 or a power source for the treadmill 20. It can meet the power requirements of the strength training machine 10 and the treadmill 20 with only one motor 312, reducing the number of power components 31, simplifying the overall structure, reducing costs and control difficulty, and improving the miniaturization level of the whole machine.

[0067] In some embodiments, both the first actuating wheel 33 and the second actuating wheel 34 are configured as gears. The first actuating wheel 33 meshes with the winding wheel 11 of the strength training machine 10, and the second actuating wheel 34 meshes with the transmission wheel 21 of the treadmill 20. Using gear meshing for transmission avoids slippage and ensures smooth and precise power transmission.

[0068] like Figure 10 As shown, in other embodiments, the transmission between the first actuating wheel 33 and the winding wheel 11, and between the second actuating wheel 34 and the transmission wheel 21, can also be replaced by a belt pulley mechanism, a sprocket mechanism, etc., depending on the actual needs. Specifically, both the first actuating wheel 33 and the second actuating wheel 34 are sprockets, with the first actuating wheel 33 and the winding wheel 11 connected by a chain drive, and the second actuating wheel 34 and the transmission wheel 21 connected by a chain drive; or both the first actuating wheel 33 and the second actuating wheel 34 are belt pulleys, with the first actuating wheel 33 and the winding wheel 11 connected by a belt drive, and the second actuating wheel 34 and the transmission wheel 21 connected by a belt drive.

[0069] Please continue reading. Figures 2 to 4 In some embodiments, the shift actuator 35 includes a shift seat 351 and a toggle assembly. The shift seat 351 is disposed on the frame 311, and the toggle assembly is rotatably disposed on the shift seat 351. The toggle assembly is connected to the clutch 32 to actuate the clutch 32 to move axially on the power shaft 313.

[0070] Specifically, the shift seat 351 is fixedly installed on the top of the frame 311 by any one of the following methods: screwing, welding, etc. The shifting component is rotatably mounted on the shift seat 351 via a rotating shaft, and has rotational freedom in both clockwise and counterclockwise directions with the axis of the rotating shaft as the center of rotation. When the shifting component is operated to rotate clockwise, the shifting component can disengage the clutch 32 on the power shaft 313 towards the first actuating wheel 33, and finally connect with the first actuating wheel 33, realizing the power connection between the motor 312 and the strength training machine 10; conversely, when the shifting component is operated to rotate counterclockwise, the shifting component can disengage the clutch 32 from the first actuating wheel 33, and move on the power shaft 313 towards the second actuating wheel 34, and finally connect with the second actuating wheel 34, realizing the power connection between the motor 312 and the treadmill 20. The shifting actuator 35 described above has a simple structure, convenient and labor-saving shifting operation, and strong feasibility.

[0071] It should be noted that the rotating component can be manually driven by the trainee or automatically driven by the configured drive unit, depending on the actual needs.

[0072] Please continue reading. Figures 5 to 7 Based on the above embodiments, the actuation assembly includes an actuation lever 352, a mounting block 353 disposed on the actuation lever 352, and a shift fork 354 disposed on the actuation lever 352. The mounting block 353 is rotatably disposed on the shift seat 351. The clutch 32 is provided with an actuation groove 321, and the shift fork 354 is inserted into the actuation groove 321.

[0073] The shift seat 351 has a U-shaped structure. Both the shift seat 351 and the mounting block 353 have aligned mounting holes, allowing the mounting block 353 to rotate freely by inserting a rotating shaft into the mounting hole. When the shift lever 352 is driven, it can rotate around the rotating shaft via the mounting block 353, and the shift lever 352 can then actuate the clutch 32, causing it to move axially. Furthermore, by providing a shift fork 354 on the shift lever 352 and inserting it into the shift groove 321, a stable connection between the shift lever 352 and the clutch 32 is ensured, guaranteeing reliable movement of the clutch 32 driven by the shift lever 352 and meeting the requirements for smooth shifting.

[0074] Specifically, the end of the actuating lever 352 forms a C-shaped arc-shaped rod, and both free ends of the arc-shaped rod are provided with shift forks 354. The actuating groove 321 is a continuous annular groove or a discontinuous annular groove structure, and is provided along the circumferential direction of the clutch 32. The two shift forks 354 are inserted into the actuating groove 321, which can further improve the driving effectiveness of the clutch 32. The actuating groove 321 axially limits the shift forks 354, thereby allowing the shift forks 354 to drive the clutch 32 to move axially, and the shift forks 354 are not easy to disengage from the actuating groove 321. In addition, when the clutch 32 rotates with the drive shaft 313, the shift forks 354 can slide in the actuating groove 321, and the shift forks 354 do not interfere with the rotation of the clutch 32. Furthermore, the arc-shaped rod can have a certain degree of elasticity to facilitate the disassembly and assembly of the actuating assembly and the clutch 32.

[0075] In this solution, the integrated training device 100 has three states: a non-use state (neutral), a first use state (strength training mode), and a second use state (running training mode). Alternatively, it may have only two use states: a first use state (strength training mode) and a second use state (running training mode). In some embodiments, the gear shifter 351 has a first gear position hole 351a, a second gear position hole 351b, and a third gear position hole 351c located on the same side, wherein the first gear position hole 351a corresponds to neutral, the second gear position hole 351b corresponds to strength training mode, and the third gear position hole 351c corresponds to running training mode.

[0076] In one embodiment, the actuation assembly further includes a first elastic element 355 and a ball bearing. The first elastic element 355 is inserted into a sliding hole in the mounting block 353, and the ball bearing abuts against the first elastic element 355. When the ball bearing engages with the first gear position hole 351a, the clutch 32 is not in contact with the first actuating wheel 33 and the second actuating wheel 34. When the ball bearing engages with the second gear position hole 351b, the clutch 32 is driven to engage with the first actuating wheel 33. When the ball bearing engages with the third gear position hole 351c, the clutch 32 is driven to engage with the second actuating wheel 34.

[0077] Alternatively, as an alternative to the above embodiment, the shift seat 351 is provided with a first shift hole 351a, a second shift hole 351b, and a third shift hole 351c, respectively. The first shift hole 351a, the second shift hole 351b, and the third shift hole 351c are arranged on opposite sides at intervals. The actuation assembly further includes a first elastic element 355, a first ball bearing 356, and a second ball bearing 357. The first elastic element 355 is inserted into the sliding hole of the mounting block 353, and the first ball bearing 356 and the second ball bearing 357 abut against opposite ends of the first elastic element 355. When the first ball bearing 356 is aligned with the first shift hole 351a... When the second ball bearing 357 is misaligned with the second gear position hole 351b and the third gear position hole 351c, the clutch 32 is not in contact with the first actuating wheel 33 and the second actuating wheel 34. When the first ball bearing 356 is misaligned with the first gear position hole 351a and the second ball bearing 357 is engaged with the second gear position hole 351b, the clutch 32 is driven to connect with the first actuating wheel 33. When the first ball bearing 356 is misaligned with the first gear position hole 351a and the second ball bearing 357 is engaged with the third gear position hole 351c, the clutch 32 is driven to connect with the second actuating wheel 34.

[0078] For ease of description, the following description will use an embodiment in which a first ball bearing 356 and a second ball bearing 357 are used, the first gear position hole 351a is located on one side of the gear shift seat 351, and the second gear position hole 351b and the third gear position hole 351c are located on the other side of the gear shift seat 351.

[0079] The first elastic element 355 is configured as a spring or other component with elastic force. The spring passes through the sliding hole, and its two ends apply an outward pushing force to the first ball 356 and the second ball 357 respectively, so that the first ball 356 and the second ball 357 are held outside the opening of the sliding hole and abut against the shift seat 351.

[0080] When the trainee manually rotates the lever 352, the first ball 356 and the second ball 357 roll on the shift seat 351, reducing frictional resistance and making it easier to rotate the lever 352. When the second ball 357 aligns with the second gear position hole 351b, due to the spring force, a portion of the second ball 357 will be inserted and fixed in the second gear position hole 351b (the diameter of the second gear position hole 351b is smaller than the diameter of the second ball 357), thus positioning the lever 352. This increases the feedback experience when operating the lever 352 and ensures that the lever 352 will not rotate arbitrarily under small external forces, ensuring gear stability.

[0081] Similarly, the same scheme of connecting the second ball 357 with the third gear hole 351c and the first ball 356 with the first gear hole 351a has the same beneficial effects as above, and will not be elaborated here.

[0082] The clutch 32 must be circumferentially connected and fixed to the first actuating wheel 33 or the second actuating wheel 34 to ensure that the clutch 32 synchronously drives the first actuating wheel 33 or the second actuating wheel 34 to rotate effectively. In some embodiments, the clutch 32 is provided with a connecting component, and the first actuating wheel 33 and the second actuating wheel 34 are provided with connecting mating parts; or, the clutch 32 is provided with connecting mating parts, and both the first actuating wheel 33 and the second actuating wheel 34 are provided with connecting components; the connecting component can connect with the connecting mating parts so that the clutch 32 can drive the first actuating wheel 33 or the second actuating wheel 34 to rotate.

[0083] Therefore, when the clutch 32 approaches the first actuator wheel 33 or the second actuator wheel 34, the connecting component will automatically connect with the corresponding connecting mating part, that is, the clutch 32 is assembled and fixed with the first actuator wheel 33 or the second actuator wheel 34, so that the clutch 32 can drive the first actuator wheel 33 or the second actuator wheel 34 to rotate synchronously.

[0084] It should be noted that the connecting mating part and the connecting component are specifically in a key-groove connection relationship. The following embodiments are only some implementation methods for realizing the key-groove connection, but are not limited thereto.

[0085] Specifically, based on the above embodiments, the connecting and mating part includes at least one slot 323, and the connecting component includes a second elastic member 324 and a locking block 325. The locking block 325 abuts against the second elastic member 324, and the locking block 325 can be locked into the slot 323 under the action of the second elastic member 324, so that the clutch 32 can be circumferentially connected and fixed with the first actuating wheel 33 or the second actuating wheel 34.

[0086] Please continue reading. Figures 5 to 7In one embodiment, the connecting and mating part is disposed at the end of the first actuating wheel 33 and the second actuating wheel 34 near the clutch 32, and the connecting assembly is installed at the end of the clutch 32. Specifically, both axial ends of the clutch 32 are provided with a second elastic element 324 and a locking block 325, and the ends of the first actuating wheel 33 and the second actuating wheel 34 near the clutch 32 are provided with a locking groove 323. When the actuating lever 352 is turned, the connecting assembly located at the axial end of the clutch 32 will be inserted into the locking groove 323. At this time, the second elastic element 324 applies an elastic thrust to the locking block 325, so that the locking block 325 can be stably locked into the locking groove 323, thereby restricting the relative rotational freedom of the clutch 32 and the first actuating wheel 33 or the second actuating wheel 34, that is, ensuring that the clutch 32 is stably connected to the first actuating wheel 33 or the second actuating wheel 34.

[0087] It should be noted that at least one slot 323 is required, which is used to cooperate with the card block 325 to achieve a transmission connection.

[0088] Furthermore, the width and number of slots 323 affect the transmission connection efficiency between the two. When the width of the slots 323 is large and the number is small, the alignment of the slots 323 and the block 325 is slow, resulting in low transmission efficiency. Conversely, when the width of the slots 323 is small (not less than the size of the block 325) and the number is large, the alignment of the slots 323 and the block 325 is fast, resulting in high transmission efficiency. In this embodiment, it is preferable that the width of the slots 323 is slightly larger than the size of the block 325, so that when the clutch 32 switches between forward and reverse, the first actuating wheel 33 or the second actuating wheel 34 connected to it can quickly and synchronously switch between forward and reverse. The width of the slot 323 is the circumferential dimension of the slot 323 along the first actuating wheel 33 or the second actuating wheel 34.

[0089] Furthermore, the connecting part also includes a snap-fit ​​hole 322, and a snap-fit ​​groove 323 is recessed in the inner wall of the snap-fit ​​hole 322. That is, the distance between the bottom of the snap-fit ​​groove 323 and the axis of the first actuating wheel 33 or the second actuating wheel 34 is greater than the distance between the inner wall of the snap-fit ​​hole 322 and the axis of the first actuating wheel 33 or the second actuating wheel 34. Since the snap-fit ​​block 325 and the snap-fit ​​groove 323 cannot be guaranteed to be accurately aligned and snap-fitted every time, the snap-fit ​​hole 322 is provided. When the snap-fit ​​block 325 and the snap-fit ​​groove 323 need to be snapped, the snap-fit ​​block 325 will first be squeezed into the snap-fit ​​hole 322 under the action of the second elastic member 324. Then, as the clutch 32 drives the snap-fit ​​block 325 to rotate, the snap-fit ​​block 325 will first align with the snap-fit ​​groove 323 closest to its rotation direction, and then spring into the snap-fit ​​groove 323 under the action of the second elastic member 324 to achieve snap-fit ​​engagement. This transmission connection method is convenient, quick and reliable.

[0090] Please continue reading. Figure 11In another embodiment, the connecting and mating part is disposed on the clutch 32, and the connecting assembly is disposed on the first actuating wheel 33 and the second actuating wheel 34. Specifically, both axial ends of the clutch 32 are provided with a snap-fit ​​hole 322 and a snap-fit ​​groove 323. The ends of the first actuating wheel 33 and the second actuating wheel 34 near the clutch 32 are provided with a second elastic element 324 and a snap-fit ​​block 325. The snap-fit ​​block 325 engages with the snap-fit ​​groove 323 under the action of the second elastic element 324 in the same manner as above, and also has the aforementioned beneficial effects, which will not be elaborated here.

[0091] In some embodiments, the connecting part includes a groove 323, and the connecting assembly includes a snap-fit ​​hole 322, a second elastic element 324, and a snap-fit ​​block 325. Specifically, the connecting part is a column protruding along the axial direction of the power shaft 313, that is, a column protruding along the axial direction of the clutch 32, the first actuator wheel 33, or the second actuator wheel 34. The groove 323 is recessed on the circumferential surface of the column. The connecting assembly has a snap-fit ​​hole 322, the inner diameter of which is not less than the outer diameter of the column. The snap-fit ​​block 325 protrudes from the inner wall of the snap-fit ​​hole 322 under the action of the second elastic element 324. When the connecting assembly engages with the connecting part, the column is accommodated in the snap-fit ​​hole 322, and the snap-fit ​​block 325 springs into the groove 323 under the action of the second elastic element 324 to achieve the snap-fit ​​engagement.

[0092] To facilitate the description of the scheme, the following example illustrates the scheme with the connecting component located on the clutch 32 and the connecting mating part located on the first actuator wheel 33 and the second actuator wheel 34.

[0093] In some other embodiments, the connecting assembly further includes a limiting groove 326, in which the second elastic member 324 is inserted, at least a portion of the locking block 325 is inserted into the limiting groove 326 and abuts against the second elastic member 324, and at least the remaining portion of the locking block 325 extends out of the opening of the limiting groove 326.

[0094] The limiting groove 326 extends radially along the clutch 32, and the opening of the limiting groove 326 penetrates the circumferential surface of the clutch 32. The second elastic element 324 and the locking block 325 are both inserted into the limiting groove 326, ensuring their stable installation. When the locking block 325 moves telescopically, it is guided by the groove wall of the limiting groove 326, guaranteeing the alignment and engagement accuracy between the locking block 325 and the locking groove 323.

[0095] In some embodiments, the locking block 325 is provided with a guide portion 325a. The guide portion 325a plays a guiding and avoidance role when the clutch 32 engages with the locking hole 322 of the first actuating wheel 33 or the second actuating wheel 34. When the guide portion 325a abuts against the hole wall of the locking hole 322, it will be subjected to a radial component force in the direction of the limiting groove 326, so that the locking block 325 can be squeezed and contracted by the hole wall of the locking hole 322, thereby retracting more smoothly into the limiting groove 326, and then extending out after passing over the hole wall of the locking hole 322 to engage with the locking groove 323.

[0096] Furthermore, the bottom of the limiting groove 326 has an insertion hole, at least a portion of the locking block 325 is accommodated in the insertion hole, and the end face of the clutch 32 has a pin hole communicating with the insertion hole, into which a pin is inserted. The tail of the locking block 325 has a step, and the tail of the locking block 325 is accommodated in the insertion hole. The step engages with the end of the pin, and the pin limits the locking block 325 in the insertion hole. This ensures that the upper end of the locking block 325 extends a certain height out of the opening of the limiting groove 326 and can engage with the locking groove 323, while preventing the locking block 325 from coming out of the limiting groove 326.

[0097] In addition, the depth of the limiting groove 326 must be greater than the sum of the length of the block 325 extending out of the limiting groove 326 and the diameter of the pin. This ensures that the block 325 can be completely contained in the limiting groove 326 when radially compressed to avoid interference with the locking hole 322.

[0098] Furthermore, the depth of the insertion hole is required to be no less than the height of the protrusion of the locking block 325 into the limiting groove 326. This allows space to be reserved for the movement of the locking block 325, ensuring that the locking block 325 is completely retracted into the limiting groove 326 when under pressure.

[0099] This application provides a comprehensive training device 100, which includes: a gear shift drive device 30 as described above, a first training machine that is pulsatorically connected to the first actuating wheel 33 of the gear shift drive device 30, and a second training machine that is pulsatorically connected to the second actuating wheel 34 of the gear shift drive device 30.

The drive wheel 21 is connected to the second actuating wheel 34. The drive wheel 21 is coaxially connected to the pulley 22. A belt 24 is fitted on the pulley 22 and the front roller 23. The front roller 23 is used to drive the running belt 25 to rotate.

[0102] Both the first actuating wheel 33 and the second actuating wheel 34 are configured as gears. The first actuating wheel 33 meshes with the first training machine for transmission, and the second actuating wheel 34 meshes with the second training machine for transmission; or...

[0104] Both the first actuating wheel 33 and the second actuating wheel 34 are configured as belt pulleys. The first actuating wheel 33 is driven by the first training machine through the belt 24, and the second actuating wheel 34 is driven by the second training machine through the belt 24.

[0105] Specifically, both the first actuating wheel 33 and the second actuating wheel 34 are configured as gears, with the first actuating wheel 33 meshing with the winding wheel 11 and the second actuating wheel 34 meshing with the transmission wheel 21; or, both the first actuating wheel 33 and the second actuating wheel 34 are configured as sprockets, with the first actuating wheel 33 meshing with the winding wheel 11 and the second actuating wheel 34 meshing with the transmission wheel 21; or, both the first actuating wheel 33 and the second actuating wheel 34 are configured as pulleys, with the first actuating wheel 33 meshing with the winding wheel 11 and the second actuating wheel 34 meshing with the transmission wheel 21.

[0106] like Figure 12 and 13 As shown, in other embodiments, the anaerobic training machine includes two winding reels 11, each connected to two pull ropes 12 and two handles 13. The two winding reels 11 are connected by a differential 40, with one of the reels 11 being driven by a first actuating wheel 33. Preferably, the differential 40 and the two winding reels 11 are driven by gears to ensure transmission accuracy. In this way, the two winding reels 11, connected by the differential 40, can share a single motor, saving costs and simplifying the overall structure. During use, the handles 13 on both sides can be pulled simultaneously or individually without interference, meeting the needs of trainees for unilateral and bilateral training.
