Description

Technical Field

[0001] The present application relates to the technical field of chin-up exercise equipment, and in particular, to a buoyancy platform for single-bar assisted training. Background Art

[0002] Currently, with the improvement of health awareness, chin-up, as a classic full-body strength training method, is favored by more and more people. It can not only effectively exercise arm strength and back muscle groups, but also play a role in enhancing body coordination and core strength. However, chin-up is quite difficult for beginners or those with relatively weak arm strength, and additional assistance is often required to complete standard movements. Therefore, various chin-up assisted training devices have gradually emerged in the market to meet the fitness needs of different people.

[0003] Common chin-up assisted devices on the market currently mainly include elastic band assisted devices, hydraulic assisted devices, and mechanical spring assisted devices. The elastic band assisted device uses the stretching and contracting characteristics of the elastic band to provide assistance, and its structure is relatively simple with low cost. The hydraulic assisted device provides stable assistance through the operation of the hydraulic cylinder and can adapt to large load changes. The mechanical spring assisted device relies on the compression and rebound of the spring to generate assistance and can, to a certain extent, help users complete chin-up movements. In addition, there are also publicly disclosed chin-up exercisers that displace a support plate up and down by pulling ropes and pulleys and are provided with a locking structure; a forced hook lock device for the lifting pedal of a publicly disclosed chin-up exerciser ensures the use safety through the cooperation of a touch pressure rod and a buckle column; a publicly disclosed chin-up trainer uses the compression of an elastic telescopic rod to provide assistance and reduce noise.

[0004] However, the above-mentioned chin-up assisted devices have obvious defects. The assistance provided by the elastic band assisted device cannot be adjusted, which cannot meet the needs of users with different weights and training requirements, and the elastic band is prone to aging, affecting the service life and use safety. Although the hydraulic assisted device can provide stable assistance, its structure is complex, resulting in high costs and being not conducive to wide promotion. The mechanical spring assisted device has a limited assistance adjustment range, is difficult to precisely adapt to the needs of different users, and has poor safety, and accidents are likely to occur. In related technologies, there are also some other chin-up assisted devices, such as those that are fixed and non-adjustable, which are inconvenient to use; or those that use an electric adjustment method and are prone to electric shock risks when encountering rain and are not suitable for outdoor use; or those that use a centering bearing and are easily damaged by factors such as rain, snow, wind, and sand; or those that use an external limit and have many risks of clamping, shearing, squeezing, etc. to the human body, especially the risk of harm to children.

[0005] Therefore, there is a problem that it is difficult to balance safety and the flexibility of assistance adjustment on the premise of reducing costs, and there is an urgent need for a buoyancy platform for single-bar assisted training. Summary of the Invention

[0006] In order to balance safety and the flexibility of assist adjustment while reducing costs, the present application provides a horizontal bar assisted training buoyancy platform.

[0007] The horizontal bar assisted training buoyancy platform provided by the present application adopts the following technical solutions: A horizontal bar assisted training buoyancy platform, comprising: A frame; A support mechanism, movably arranged on the frame, and the support mechanism is used for a user to step on; An adjustment mechanism, arranged on the support mechanism; An assist mechanism, arranged on the frame and connected to the adjustment mechanism, and the adjustment mechanism is used for adjusting the assist magnitude of the assist mechanism; A locking mechanism, including an automatic locking component and a manual locking component, the automatic locking component and the manual locking component are respectively arranged on the support mechanism, and the automatic locking component and the manual locking component are respectively used for connecting to the frame to lock the support mechanism.

[0008] By adopting the above technical solutions, the user can adjust the assist magnitude according to their own needs, so that the device can adapt to users with different weights and training levels. The movable arrangement between the support mechanism and the frame, combined with the precise control of the adjustment mechanism over the assist mechanism, ensures that the assist provided during the training process is stable and adjustable. In addition, the dual locking design of the automatic locking component and the manual locking component effectively guarantees the safety of the user during stepping on and off the pedal and during the training process, and avoids accidents caused by accidental unlocking. The overall structure is simple, the operation is convenient, the production cost is reduced, and at the same time the practicability and reliability of the equipment are improved.

[0009] Optionally, the assist mechanism includes a support base, a connecting shaft and a plurality of assist members, the support base is arranged at the bottom of the frame, the connecting shaft is arranged on the support base, and one end of the assist member is hinged to the connecting shaft; A support beam is arranged on the support mechanism, the adjustment mechanism includes a driving member, a movable seat, a guiding component and an outer cover, the driving member and the guiding component are respectively arranged on the support beam, the movable seat is arranged on the guiding component and connected to the driving member, the end of the assist member far from the connecting shaft is hinged to the movable seat, the driving member is used for driving the movable seat to move, the guiding component is used for guiding the movable seat, and the outer cover is arranged on the support mechanism and covers the guiding component and the movable seat.

[0010] By adopting the above technical solution, one end of the assisting member is hinged to the connecting shaft, and the other end is hinged to the movable seat. Thus, when the driving member drives the movable seat to move, the change in the position of the movable seat will change the angle and tension of the assisting member, achieving precise adjustment of the assisting force. Moreover, the guiding assembly can ensure the stable movement of the movable seat, and the outer cover can effectively brake the guiding assembly and the movable seat, preventing dust or other impurities from entering, and ensuring the smoothness and reliability of the adjustment process. This structural design not only improves the flexibility and adaptability of the device, but also enhances the overall stability and durability, meeting the requirements of different users for the assisting force magnitude.

[0011] Optionally, the guiding assembly includes two connecting plates and a plurality of pulleys. The two connecting plates are arranged oppositely, and the plurality of pulleys are movably arranged between the two connecting plates. The support beam is arranged through the spaces between the plurality of pulleys, and the movable seat is respectively connected to the two connecting plates.

[0012] By adopting the above technical solution, the two oppositely arranged connecting plates provide a stable installation position for the plurality of pulleys, and the support beam passes through the spaces between the plurality of pulleys. The pulleys form multi-point support for the support beam, enabling the pulleys to move stably along the support beam. Thus, through the cooperation of the pulleys and the connecting plates, the frictional resistance during the movement of the movable seat can be significantly reduced, thereby improving the accuracy and smoothness of the adjustment of the initial force of the assisting member. At the same time, this structural design makes the force on the support beam more uniform, effectively extending the service life of the device and providing a more stable and comfortable training experience for users.

[0013] Optionally, the guiding assembly includes a slide rail. The slide rail is arranged inside the outer cover and is arranged along the moving direction of the movable seat. The movable seat is slidably connected to the slide rail.

[0014] By adopting the above technical solution, the slide rail is arranged inside the outer cover and the movable seat is slidably connected to the slide rail. This structural design can ensure that the movable seat moves smoothly along a predetermined trajectory during the adjustment process, avoiding problems such as inaccurate adjustment of the initial force of the assisting member caused by shaking or deviation. Moreover, the use of the slide rail not only improves the stability of the device, but also simplifies the structure of the guiding assembly, reducing the manufacturing and maintenance costs.

[0015] Optionally, the guiding assembly includes a guiding rod. The guiding rod is arranged inside the outer cover and is arranged along the moving direction of the movable seat. The movable seat is slidably connected to the guiding rod.

[0016] By adopting the above technical solution, the setting of the guide rod can provide stable linear motion guidance for the movable seat, ensuring that it will not shift or jam when adjusting the initial force of the assisting member, and enabling the assisting member to maintain a uniform distribution during the force application process, avoiding affecting the training effect due to the deviation of the force application direction. In addition, the sliding connection design between the movable seat and the guide rod not only simplifies the structure, but also reduces the manufacturing cost, while ensuring the smoothness and accuracy of the adjustment process, thereby improving the user experience.

[0017] Optionally, the guiding assembly includes a guide plate, a connecting ring and rolling members. The guide plate is arranged inside the outer cover. The connecting ring is movably sleeved on the guide plate and connected to the movable seat. The rolling members are arranged on the movable seat and in contact with the guide plate.

[0018] By adopting the above technical solution, the cooperation between the guide plate and the connecting ring can ensure the stability of the movable seat during movement, avoiding deviation when adjusting the assisting force. The setting of the rolling members further reduces the friction between the movable seat and the guide plate, making the adjustment process smoother. This structural design not only improves the reliability of the device, but also extends the service life of the components, thereby ensuring that the assisting force of the assisting mechanism can be accurately adjusted and stably output.

[0019] Optionally, the supporting mechanism includes a connecting rod and a pedal. One end of the connecting rod is rotatably connected to the frame body, and the other end of the connecting rod is connected to the pedal. A locking rod is arranged on the frame body. There are two sets of automatic locking components, and the two sets of automatic locking components are respectively arranged on the pedal and corresponding to the stepping positions of the user's two feet. The automatic locking component includes a touch pressure rod, a first elastic member, a rotating piece, a linkage rod and a locking hook. The touch pressure rod is slidably arranged on the pedal, and both ends of the touch pressure rod respectively penetrate through the two end faces of the pedal. The rotating piece is rotatably connected to the bottom of the pedal and in contact with the touch pressure rod. The first elastic member is respectively connected to the rotating piece and the pedal. The linkage rod is respectively hinged to the rotating piece and the locking hook. The locking hook is hinged to the connecting rod. When the touch pressure rod is pressed down, the locking hook disengages from the locking rod.

[0020] By adopting the above technical solution, when the user steps on the pedals with both feet, the foot pressure can be transmitted to the rotating vane through the pressure contact rod, causing the rotating vane to rotate. The rotation of the rotating vane drives the locking hook to rotate around the hinge point through the linkage rod, so that the locking hook disengages from the locking rod, realizing the unlocking of the support mechanism. When the user leaves the pedal after the training, the restoring force of the first elastic member resets the rotating vane, and then drives the locking hook to lock with the locking rod again, ensuring the automatic locking of the support mechanism. This design controls the locking state through foot pressure, without manual operation, improving the convenience and safety of use. At the same time, the bilateral locking structure further improves the stability of the device, effectively preventing potential safety hazards caused by the failure of unilateral locking.

[0021] Optionally, a hook is provided on the frame body. The manual locking assembly includes a clamping ring and a handle provided on the clamping ring. The clamping ring is rotatably connected to the connecting rod, and the clamping ring is used to lock with the hook.

[0022] By adopting the above technical solution, after the user completes the training, the clamping ring can be locked with the hook by pulling the handle backward, so as to stably fix the support mechanism at the lowest position. This design can not only prevent equipment damage caused by accidental movement of the support mechanism, but also ensure the safety of the equipment before the next user uses it. At the same time, since the clamping ring is rotatably connected to the connecting rod, its flexible rotation characteristics make the locking operation more convenient, effectively improving the user experience. In addition, the structure is simple and reliable, easy to manufacture and maintain, further reducing the overall cost.

[0023] Optionally, a protective cover is provided on the frame body, a rotating rod is provided on the connecting rod, the rotating rod passes through the protective cover and is rotatably connected to the protective cover and the frame body respectively. A linkage assembly and a braking assembly are respectively provided in the protective cover. The linkage assembly is connected to the braking assembly and the rotating rod respectively. When the rotation speed of the rotating rod exceeds a specified value, the linkage assembly can drive the braking assembly to limit the rotation of the rotating rod.

[0024] By adopting the above technical solution, when the user is performing pull-up training, if the pedal descends too fast due to improper operation or external force, the braking assembly can quickly respond when the rotating rod rotates at an excessive speed and effectively limit the rotating rod, thus avoiding the impact or accidental injury caused by the excessive descent of the pedal due to inertia. This design not only improves the overall stability of the equipment, but also provides additional safety protection for the user, ensuring that the training process is more reliable and reassuring.

[0025] Optionally, the linkage assembly includes a first gear, a second gear and a rotating shaft. The first gear is coaxially arranged on the rotating rod. The rotating shaft is rotatably arranged in the protective cover and is parallel to the rotating rod. The second gear is coaxially arranged on the rotating shaft and meshes with the first gear. The number of teeth of the first gear is greater than that of the second gear. An annular friction groove is formed on the rotating rod along the direction of its own axis. The braking assembly includes a turntable, an arc-shaped baffle, a friction block and a second elastic member. The turntable is coaxially arranged on the rotating shaft. An arc-shaped groove is formed on the turntable along the direction of its own axis. A sliding groove is formed on the turntable along the direction perpendicular to its own axis. The sliding groove communicates with the arc-shaped groove. The arc-shaped baffle is slidably arranged in the arc-shaped groove. The friction block is slidably arranged in the sliding groove and abuts against the arc-shaped baffle. The second elastic member is arranged in the sliding groove and is connected to the friction block. When the arc-shaped baffle is separated from the friction block, the second elastic member can push the friction block to be inserted into the annular friction groove.

[0026] By adopting the above technical solution, when the rotating rod rotates, the rotating rod can drive the second gear to rotate through the first gear, and the second gear can drive the turntable to rotate through the rotating shaft. And because the number of teeth of the first gear is greater than that of the second gear, when the rotation speed of the rotating rod exceeds the specified value, the rotation speed of the turntable increases. The arc-shaped baffle slides along the arc-shaped groove under the action of inertia and is separated from the friction block. At this time, the second elastic member pushes the friction block to move along the sliding groove so that the friction block is inserted into the annular friction groove on the rotating rod and fits with the inner wall of the annular friction groove, thereby realizing the limitation and braking of the rotating rod. This design can timely limit the rotation speed of the rotating rod when the user operates improperly or the equipment is abnormal, prevent potential safety hazards caused by the violent swing of the pedal assembly, and significantly improve the safety of equipment use. In addition, this mechanical braking mechanism does not require additional power support and has the advantages of rapid response and high reliability.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the mutual cooperation of the adjustment mechanism, the boosting mechanism, the automatic locking assembly and the manual locking assembly, on the one hand, the boosting force can be accurately adjusted to meet the needs of users with different weights and training requirements. On the other hand, through the dual locking mechanism, the safety of the user during the training process is ensured, and the risk of unstable center of gravity or falling caused by accidental unlocking is prevented. Thus, on the premise of reducing costs, both safety and the flexibility of boosting force adjustment are taken into account. 2. Through the mutual cooperation of the connecting plate and the pulley, on the one hand, the support stability of the movable seat is effectively improved, and on the other hand, the frictional resistance during the movement of the movable seat can be significantly reduced, thereby improving the accuracy and smoothness of the adjustment of the initial force of the assisting member, making the supporting beam more evenly stressed, effectively extending the service life of the equipment, and providing a more stable and comfortable training experience for users; 3. Through the mutual cooperation of the linkage assembly and the braking assembly, when the pedal descends too fast due to improper operation or external force, the braking assembly can quickly limit the rotating rod to prevent the pedal from dropping excessively due to inertia and causing impact or accidental injury to the user. Thus, on the one hand, the overall stability of the equipment is improved, and on the other hand, additional safety protection can be provided for the user to ensure that the training process is more reliable and reassuring.

[0043] Embodiment 1 Refer to Figure 1 and Figure 2, A horizontal bar assisted training buoyancy platform includes a frame body 1, a support mechanism 2, an adjustment mechanism 3, a boosting mechanism 4 and a locking mechanism 5. Among them, the support mechanism 2 is movably arranged on the frame body 1 for users to step on; the adjustment mechanism 3 and the locking mechanism 5 are respectively arranged on the support mechanism 2, the boosting mechanism 4 is arranged on the frame body 1 and connected to the adjustment mechanism 3, the adjustment mechanism 3 is used to adjust the boosting force of the boosting mechanism 4, and the locking mechanism 5 is used to lock the support mechanism 2. This device realizes the adjustability of the boosting force through the adjustment mechanism 3, and at the same time ensures the safety during the training process through the locking mechanism 5.

[0044] The frame body 1 is made of stainless steel, with high strength and corrosion resistance. The support mechanism 2 includes a connecting rod 21 and a pedal 22. Among them, one end of the connecting rod 21 is fixedly connected to the pedal 22, and both the pedal 22 and the connecting rod 21 are made of non-metallic materials, and the surface of the pedal 22 is provided with anti-slip patterns.

[0045] Refer to Figure 2 , A rotating rod 23 is fixedly connected to the end of the connecting rod 21 away from the pedal 22, and the rotating rod 23 is rotatably connected to the frame body 1, so that the connecting rod 21 can drive the pedal 22 to rotate. In other embodiments, the rotating rod 23 may not be provided, and the connecting rod 21 may be directly rotatably connected to the frame body 1.

[0046] Refer to Figure 2 and Figure 3 , A support beam 24 is fixedly connected to the connecting rod 21, and the support beam 24 is used to support the adjustment mechanism 3. The adjustment mechanism 3 includes a driving part 31, a movable seat 32, a guiding component 33 and an outer cover 34. Among them, the outer cover 34 is installed on the support beam 24.

[0047] In this embodiment, the bottom of the outer cover 34 is open to avoid interference with the movement of the movable seat 32, and an observation slot 341 is opened at the top of the outer cover 34. A transparent acrylic plate is arranged in the observation slot 341, and a weight scale is arranged beside the observation slot 341. A pointer is arranged on the movable seat 32, so that users can observe the position of the pointer relative to the weight scale through the transparent acrylic plate to judge the boosting force.

[0048] Refer to Figure 2 and Figure 3 , The driving part 31 includes a handwheel 311 and a lead screw 312. Among them, the lead screw 312 is rotatably connected to the support beam 24, and one end of the lead screw 312 extends into the outer cover 34, and the other end of the lead screw 312 extends out of the outer cover 34 and is fixedly connected to the handwheel 311, so as to facilitate driving the lead screw 312 to rotate by rotating the handwheel 311. In other embodiments, the handwheel 311 can also be replaced by a motor.

[0049] The movable seat 32 is made of aluminum alloy. The movable seat 32 is located in the outer cover 34 and is threadedly connected to the screw rod 312 . Therefore, when the screw rod 312 rotates, the movable seat 32 can move along the length direction of the screw rod 312 .

[0050] Reference Figure 3 The guide assembly 33 includes two connecting plates 331 and a plurality of pulleys 332. The two connecting plates 331 are arranged opposite to each other, and the movable seat 32 is fixedly connected to the two connecting plates 331 respectively, so that the movable seat 32 can be stably supported by the two support plates.

[0051] A plurality of pulleys 332 are rotatably disposed between the two connecting plates 331, and the support beam 24 is disposed between the plurality of pulleys 332. In this embodiment, three pulleys 332 are provided, and the three pulleys 332 are distributed in a triangular shape, thereby facilitating the improvement of the stability of the pulleys 332 when moving along the support beam 24.

[0052] When the movable seat 32 moves, it drives the pulley 332 via the two connecting plates 331, causing the pulley 332 to roll on the support beam 24. This not only guides the movable seat 32, but also significantly reduces friction during movement, thereby improving the accuracy and smoothness of the movement of the movable seat 32. This structural design also ensures a more even force distribution on the support beam 24, effectively extending the service life of the equipment and providing users with a more stable and comfortable training experience.

[0053] Reference Figure 2 and Figure 3 The power-assisting mechanism 4 includes a support base 41, a connecting shaft 42, and a plurality of power-assisting members 43. The support base 41 is mounted on the bottom of the frame 1, the connecting shaft 42 is mounted on the support base 41, and two power-assisting members 43 are provided, and the two power-assisting members 43 are respectively arranged on both sides of the movable base 32.

[0054] One end of the assisting member 43 is hinged on the connecting shaft 42, and the other end is hinged to the movable seat 32. In this embodiment, the assisting member 43 is a gas spring, and the gas spring is made of SUS316 stainless steel.

[0055] When the power assisting force needs to be adjusted, the handwheel 311 is rotated, and the handwheel 311 drives the screw rod 312 to rotate to drive the movable seat 32 to move, and the movable seat 32 drives the pulley 332 and the power assisting member 43 to move to adjust the angle of the power assisting member 43 and change the length of the power assisting member 43, thereby realizing the adjustment of the initial force of the power assisting member 43.

[0056] Reference Figure 2, the locking mechanism 5 includes an automatic locking component 51 and a manual locking component 52. Among them, there are two sets of automatic locking components 51, and the two sets of automatic locking components 51 are respectively arranged on the pedal 22 and set corresponding to the stepping positions of the user's two feet.

[0057] Referring to Figure 4 and Figure 5 , the automatic locking component 51 includes a touch pressure rod 511, a first elastic member 512, a rotating piece 513, a linkage rod 514 and a locking hook 515. Among them, the touch pressure rod 511 is slidably arranged on the pedal 22, both ends of the touch pressure rod 511 penetrate through the two end faces of the pedal 22 and are arranged, the rotating piece 513 is rotatably connected to the bottom of the pedal 22 and contacts the touch pressure rod 511, one end of the rotating piece 513 away from the touch pressure rod 511 is hinged to the linkage rod 514, and one end of the linkage rod 514 away from the rotating piece 513 is hinged to the locking hook 515, and the locking hook 515 is hinged to the connecting rod 21.

[0058] A locking rod 11 is arranged on the frame body 1, and the first elastic member 512 is respectively connected to the rotating piece 513 and the pedal 22. In this embodiment, the first elastic member 512 is a tension spring, so as to facilitate using the first elastic member 512 to pull the rotating piece 513, so that the rotating piece 513 drives the locking hook 515 to rotate through the linkage rod 514, and further enables the locking hook 515 to hook the locking rod 11. At this time, the pedal 22 is locked in the lowest position.

[0059] When the user steps on the pedal 22, the foot pressure can be transmitted to the rotating piece 513 through the touch pressure rod 511, causing the rotating piece 513 to rotate. The rotating piece 513 drives the locking hook 515 to rotate through the linkage rod 514, so that the locking hook 515 is disengaged from the locking rod 11, thereby realizing the unlocking operation. At this time, the first elastic member 512 is in a compressed state.

[0060] Referring to Figure 5 , the manual locking component 52 includes a clamping ring 521 and a handle 522 fixedly connected to the clamping ring 521, and the clamping ring 521 is rotatably connected to the connecting rod 21. A hanging hook 411 is fixedly connected to the support seat 41. When the user finishes training, the pedal 22 can be stably fixed in the lowest position by pulling the handle 522 backward to lock the clamping ring 521 with the hanging hook 411. In other embodiments, the hanging hook 411 can also be installed on the frame body 1.

[0061] In this embodiment, the dual-locking design of the automatic locking component 51 and the manual locking component 52 effectively ensures the safety of the user when getting on and off the pedal 22 and during the training process, and avoids accidents caused by accidental unlocking.

[0062] Referring to Figure 1, a horizontal bar 6 is installed on the frame body 1. The horizontal bar 6 is arranged close to the pedal 22, and the horizontal bar 6 includes two columns 61 and a grip bar 62 detachably connected to the two columns 61 respectively. Among them, the two columns 61 are respectively arranged on both sides of the pedal 22, and a plurality of positioning holes 611 are formed on the columns 61, and the plurality of positioning holes 611 are evenly distributed along the height direction of the columns 61.

[0063] A screw 621 is threadedly connected to the grip bar 62. The screw 621 is inserted into the positioning hole 611 and threadedly connected to the column 61, so as to facilitate fixing the grip bar 62 to the column 61. And because there are a plurality of positioning holes 611, users can select appropriate positioning holes 611 to install the grip bar 62 according to their own height or usage habits, so as to adjust the height of the grip bar 62 and make the horizontal bar 6 adapt to the usage needs of different people.

[0064] The implementation principle of a horizontal bar assisted training buoyancy platform according to an embodiment of the present application is as follows: when a user needs to perform pull-up training, the user first steps on the pedal 22 with both feet to apply pressure to the two touch pressure rods 511 respectively. The touch pressure rod 511 applies pressure to the rotating piece 513, so that the rotating piece 513 rotates. The rotating piece 513 drives the locking hook 515 to rotate through the linkage rod 514, so that the locking hook 515 is disengaged from the locking rod 11, and at the same time, the handle 522 is pushed forward, so that the clamping ring 521 is unlocked from the hanging hook 411. Then rotate the handwheel 311, and the handwheel 311 drives the movable seat 32 to move through the lead screw 312. The movable seat 32 drives the assisting member 43 to move, so as to adjust the initial force of the assisting member 43 to an appropriate value.

[0065] Finally, the user grabs the grip bar 62 with both hands and starts to do pull-up movements. As the user applies force, the user's body gradually rises. At the same time, the assisting member 43 pushes the pedal 22 to rise through the connecting rod 21 to assist the user to complete the pull-up action.

[0066] In this embodiment, the surface of the horizontal bar assisted training buoyancy platform is subjected to shot peening hardening and purification green environmental protection process treatment, and the surface is sprayed with outdoor environmental protection non-toxic polyester powder and electrostatic powder to meet the outdoor corrosion resistance requirements of the product, thereby reducing the possibility of device damage caused by factors such as rain, snow and wind to a certain extent. And the horizontal bar assisted training buoyancy platform in the present application does not use an electric adjustment method, avoiding the risk of electric shock and being more suitable for outdoor environments.

[0067] Embodiment 2 Refer to Figure 6 , the difference between this embodiment and Embodiment 1 is that the guiding component 33 includes a slide rail 333.

[0068] There are two slide rails 333, and the two slide rails 333 are installed on the support beam 24 and symmetrically arranged on both sides of the lead screw 312, and the slide rails 333 are arranged parallel to the lead screw 312. In this embodiment, the movable seat 32 is a slide table, and the movable seat 32 is respectively slidably connected to the two slide rails 333, so as to ensure that the movable seat 32 moves smoothly along a predetermined trajectory during the adjustment process, and avoid the problem that the initial force adjustment of the boosting member 43 is inaccurate due to shaking or deviation.

[0069] In this embodiment, the stroke of the movable seat 32 is 250 mm, the precision of the lead screw is 0.03 mm, it can carry a load of 200 KG in the horizontal direction and 150 KG in the vertical direction.

[0070] Embodiment 3 Referring to Figure 7 , the difference between this embodiment and Embodiment 1 is that the guiding assembly 33 includes a guiding rod 334.

[0071] There are two guiding rods 334, and the two guiding rods 334 are installed on the support beam 24 and symmetrically arranged on both sides of the lead screw 312, and the two guiding rods 334 are respectively parallel to the lead screw 312. The two guiding rods 334 respectively pass through the movable seat 32 and are slidably connected to the movable seat 32, so as to provide a stable linear motion guide for the movable seat 32, ensure that it will not deviate or get stuck when adjusting the initial force of the boosting member 43, and make the boosting member 43 maintain a uniform distribution during the force application process, and avoid affecting the training effect due to the deviation of the force application direction.

[0072] It should be noted that the guiding rod 334 and the movable seat 32 are connected by a linear bearing to ensure smooth movement.

[0073] Embodiment 4 Referring to Figure 2 and Figure 8 , the difference between this embodiment and Embodiment 1 is that the guiding assembly 33 includes a guiding plate 335, a connecting ring 336 and a rolling member 337.

[0074] The guiding plate 335 is installed in the outer cover 34, and the guiding plate 335 is spaced from the inner surface of the side of the outer cover 34 away from the support beam 24. The connecting ring 336 is movably sleeved on the guiding plate 335 and fixedly connected to the movable seat 32. The rolling member 337 is installed on the movable seat 32 and contacts the guiding plate 335. In this embodiment, the rolling member 337 is a bearing.

[0075] The coordination of the guide plate 335 and the connecting ring 336 ensures the stability of the movable seat 32 during movement, preventing it from shifting during adjustment of the assist force. The provision of the rolling element 337 further reduces the friction between the movable seat 32 and the guide plate 335, facilitating smoother adjustment. This structural design not only improves the reliability of the device but also extends the service life of its components, thereby ensuring that the assist force of the assist mechanism 4 can be precisely adjusted and stably output.

[0076] Example 5 Reference Figure 9 and Figure 10 The difference between this embodiment and embodiment 1 is that a protective cover 12 is installed on the frame 1, and a linkage component 13 and a brake component 14 are respectively provided in the protective cover 12.

[0077] The rotating rod 23 passes through the protective cover 12 and is rotatably connected to the protective cover 12 and the frame 1, respectively. An annular friction groove 231 is defined on the rotating rod 23 around its axis. The linkage assembly 13 comprises a first gear 131, a second gear 132, and a rotating shaft 133. The first gear 131 is coaxially mounted on the rotating rod 23. The rotating shaft 133 is rotatably connected within the protective cover 12 and parallel to the rotating rod 23. The second gear 132 is coaxially mounted on the rotating shaft 133 and meshes with the first gear 131.

[0078] In this embodiment, the number of teeth on the first gear 131 is greater than the number of teeth on the second gear 132. This allows the second gear 132 to rotate at a greater angular velocity when the rotating rod 23 drives the first gear 131 to rotate at a small angle. It should be noted that the specific number of teeth on the first gear 131 and the second gear 132 can be designed based on actual needs and will not be described in detail in this embodiment.

[0079] Reference Figure 10 and Figure 11 The brake assembly 14 includes a rotating disc 141, an arc-shaped baffle 142, a friction block 143, and a second elastic member 144. The rotating disc 141 is coaxially arranged on the rotating shaft 133, and has an arc-shaped groove 1411 formed around its own axis. The rotating disc 141 also has a sliding groove 1412 formed perpendicular to its own axis, and the sliding groove 1412 is connected to the arc-shaped groove 1411.

[0080] The arc-shaped baffle 142 is slidably disposed in the arc-shaped groove 1411, the friction block 143 is slidably disposed in the groove 1412, and the second elastic member 144 is disposed in the groove 1412 and connected to the friction block 143. In this embodiment, the second elastic member 144 is a spring, so that the second elastic member 144 can be used to drive the friction block 143 to slide out of the groove 1412.

[0081] A limiting block 1413 is provided on the turntable 141. The limiting block 1413 abuts against the friction block 143 and is used to limit the friction block 143 within the sliding groove 1412 to prevent the friction block 143 from detaching from the sliding groove 1412.

[0082] In the initial state, the second elastic member 144 pushes the friction block 143 to abut against the arc-shaped baffle 142. In this state, it is not easy for the arc-shaped baffle 142 to separate from the friction block 143.

[0083] When the rotating rod 23 rotates normally, the rotating rod 23 drives the second gear 132 to rotate through the first gear 131. The second gear 132 drives the turntable 141 to rotate through the rotating shaft 133. The turntable 141 drives the second elastic member 144, the friction block 143, and the arc-shaped baffle 142 to rotate. At this time, the friction block 143 remains in contact with the arc-shaped baffle 142.

[0084] When the rotation speed of the rotating rod 23 exceeds the specified value, the rotation speed of the turntable 141 also exceeds the specified value. The arc-shaped baffle 142 slides within the arc-shaped groove 1411 under the action of inertia and disengages from the friction block 143. At this time, the second elastic member 144 pushes the friction block 143 to move along the sliding groove 1412 so that the friction block 143 is inserted into the annular friction groove 231 on the rotating rod 23 and fits against the inner wall of the annular friction groove 231, thereby achieving the limiting and braking of the rotating rod 23.

[0085] When the user operates improperly, or the equipment is abnormal or damaged, the pedal 22 will quickly fall downward or swing violently, which is likely to cause potential safety hazards. At this time, through the mutual cooperation of the linkage assembly 13 and the braking assembly 14, the rotation speed of the rotating rod 23 can be limited in a timely manner, reducing potential safety hazards and significantly improving the safety of equipment use. In addition, this mechanical protection mechanism does not require additional power support and has the advantages of rapid response and high reliability.

[0086] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the braking scope of the present application.
