Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, and in particular relates to an integrated leg press and squat machine. Background Technology

[0002] Leg press machines and squat machines are common fitness equipment, used for leg strength training and glute / thigh muscle training, respectively. Leg press machines help users work the quadriceps by simulating a pushing motion, while squat machines work the glutes and hamstrings by simulating a squatting motion. In recent years, combined leg press and squat machines have appeared on the market. These machines integrate leg press and squat functions into one machine, aiming to improve space utilization and meet multiple training needs.

[0003] The existing leg press squat machine uses a rotating limit device, which includes a pivot, handles, and a limit rod. The user rotates the pivot by operating the handle, positioning the limit device below the weight-bearing structure that is moving up and down the frame, thus preventing further descent and stopping the weight-bearing structure. There are two sets of limit devices, located on both sides of the frame, allowing the user to easily grasp the handles and operate the machine, avoiding obstruction of the normal movement of the weight-bearing structure. Simultaneously, when the weight-bearing structure is stopped, both sides are supported, ensuring its stability.

[0004] However, the existing limit structure has many drawbacks: 1. Complex operation: The dual-rotation design requires simultaneous operation of both sides, which increases the user's operational burden. Especially for beginners or users unfamiliar with the equipment, improper operation can easily lead to safety hazards; 2. Insufficient safety: In the process of limit stopping, if one side of the device fails or is not adjusted properly, the equipment may become unbalanced, increasing the risk of injury to the user. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, according to embodiments of this disclosure, a combined leg press and squat machine is proposed, including...

[0007] The rack includes:

[0008] Base frame;

[0009] The main frame is mounted on the base frame;

[0010] The sub-frame is mounted on the base frame and is positioned opposite the bottom of the main frame;

[0011] The moving parts are mounted on the main frame in a height-adjustable manner and are used to install counterweight components;

[0012] A limiting component, mounted on the main frame, includes:

[0013] Drive unit, hinged to the main frame;

[0014] The control lever is provided with an operating part and a drive part; the drive part is connected to a drive base to drive the drive base to rotate; the operating part extends to one side of the main frame for the user to hold.

[0015] The limiting seat is hinged to the main frame and connected to the drive seat through a transmission link to drive the limiting seat to rotate;

[0016] A limit rod is provided on the limit seat and is used to move between the first position and the second position as the limit seat rotates;

[0017] When the limiting rod moves to the first position, the limiting rod is located on the side of the moving part closer to the main frame; when the limiting rod moves to the second position, the limiting rod is opposite to the moving part in the direction of movement of the moving part, and is used to abut against the middle of the end face of the moving part closer to the sub-frame.

[0018] In the technical solution, the limiting component is designed as a single-handle multi-link mechanism. Users only need to operate one lever to achieve the limiting and stopping function, avoiding the complexity of the existing dual-rotation design that requires simultaneous operation of both handles, thus reducing the difficulty of operation. It is especially suitable for beginners or users unfamiliar with the equipment. The limiting lever moves between the first and second positions by rotating, which can either stop or release the limiting. When the limiting is in operation, the limiting lever is against the middle of the end face of the moving part, which can effectively prevent the equipment from becoming unbalanced, ensure the stability and reliability of the limiting and stopping, and reduce the risk of injury to the user.

[0019] In some embodiments, the main frame is provided with a mounting base, and the limiting seat is hinged to the mounting base;

[0020] An elastic element is provided between the first mounting post on the limiting seat and the second mounting post on the mounting base, so that the elastic element drives the limiting seat to move the limiting rod to the first position.

[0021] In the technical solution, the design of the elastic element allows the limit rod to be released and automatically reset to the first position when the pressure of the moving part is eliminated, without the need to operate the lever, simplifying the operation process and improving ease of use; on the other hand, the elastic element can also keep the limit rod in the first position, preventing the limit rod from moving on its own and obstructing the raising and lowering of the moving parts during normal training.

[0022] In some embodiments, the main frame includes:

[0023] Support beam;

[0024] Guide shafts are mounted on the support beam; there are two guide shafts, both parallel to the support beam and respectively located on both sides of the support beam; guide sleeves on both sides of the moving part are respectively fitted onto the two guide shafts to allow the moving part to slide up and down along the guide shafts;

[0025] The drive seat and the limit seat are both mounted on the support beam; the limit rod is U-shaped and is used to ensure that when it is in contact with the end face of the moving part, the two ends of the limit rod are located on both sides of the support beam.

[0026] In the technical solution, the structural design adopts a single beam structure, which is simpler than the double beam structure of the main frame, with lower manufacturing cost and maintenance difficulty, and occupies less space. Furthermore, the design of the guide shaft and guide sleeve allows the moving parts to slide smoothly along the guide shaft. On the other hand, it makes it easier to install the limiting rod in the center. Moving it to the second position will align it with the center of the moving parts. The U-shaped structure ensures that it contacts the moving parts symmetrically, achieving stable limiting and support for the moving parts.

[0027] In some embodiments, the main frame further includes:

[0028] There are two limit frames, which are respectively set at both ends of the support beam to restrict the movement of moving parts; the two ends of the guide shaft are respectively set on the two limit frames.

[0029] In the technical solution, the structural design can effectively limit the range of movement of moving parts, prevent the moving parts from exceeding the design range, and avoid equipment damage or user injury; on the other hand, the connection design between the limit frame and the support beam not only provides installation and fixation for the guide shaft, but also makes the entire main frame structure more stable and improves the overall stability of the equipment.

[0030] In some embodiments, the support beam is inclined and the moving parts are attached to the upper surface of the support beam.

[0031] In the technical solution, the structural design avoids excessive leg inversion when users perform leg press training, making it easier to maintain body stability and use all the force to resist the load generated by the moving parts and counterweights, ensuring training effectiveness and improving the user experience; on the other hand, the support beam can provide stable support for the moving parts during the lifting and lowering process, improving stability during training.

[0032] In some embodiments, the main frame further includes:

[0033] The inclined bracing beam is set at an angle; one end of the inclined bracing beam is connected to the support beam, and the other end is connected to the base frame; a counterweight storage rod is set on the inclined bracing beam, which is used to install counterweight components.

[0034] In the technical solution, the diagonal bracing beam enhances the overall structural strength of the main frame and improves the durability of the equipment; the design of the counterweight storage bar makes the installation and adjustment of the counterweight components more flexible and can meet the training needs of different users.

[0035] In some embodiments, the operating part is provided with a pull-down handle and a pull-up handle;

[0036] One end of the lower handle is connected to the drive unit, and the other end extends toward the upper surface of the seat cushion located away from the bottom of the main frame, and connects to one end of the upper handle;

[0037] The end of the upper handle away from the lower handle extends towards the moving part.

[0038] In the technical solution, the structural design allows users to easily perform limit operations, whether standing or sitting; on the other hand, the extended upper handle can accommodate users of different heights and body types, improving the versatility of the device.

[0039] In some embodiments, the moving parts include:

[0040] A movable base is mounted on the main frame; the movable base is equipped with a counterweight bar, which is used to install counterweight components.

[0041] There are two shoulder supports, one on each side of the movable seat;

[0042] The upper foot pedal is hinged to the movable seat; a stop block is provided on the upper foot pedal, which is used to abut against the movable seat to prevent the upper foot pedal from flipping upward and to limit the upper foot pedal to be perpendicular to the movable seat.

[0043] In the technical solution, the hinged design of the upper foot pedal allows the foot pedal to be folded or unfolded, enabling switching between the two functions of leg press and squat, thus improving the versatility of the equipment; on the other hand, the design of the stop block can effectively prevent the upper foot pedal from flipping upwards, ensuring the safety of the user during leg press training.

[0044] In some of these embodiments, a backrest panel is further included;

[0045] The upper surface of the subframe is equipped with a foot pedal, and the bottom of the main frame is equipped with a seat cushion, which is located on the side of the main frame closest to the base frame.

[0046] The backrest can be detachably mounted on the upper or lower foot pedal.

[0047] In the technical solution, the detachable design of the backrest allows it to be installed on the upper or lower foot pedals, adapting to different training modes, improving the flexibility of the equipment, and enabling each training mode to provide users with more comfortable support.

[0048] In some embodiments, the bottom end of the subframe is hinged to the base frame, and a telescopic link is provided between the top end of the subframe and the base frame.

[0049] In the technical solution, the telescopic linkage is designed to be adjustable according to the user's body shape and posture, changing the tilt angle of the subframe and improving the flexibility of the equipment.

[0050] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0063] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0065] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0066] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0067] like Figures 1 to 6 As shown in an illustrative embodiment of the inverted squatting machine of this utility model, the inverted squatting machine includes a frame 1, a moving part 2, and a limiting component 3.

[0068] The frame 1 includes a base frame 101, a main frame 102, and a sub-frame 103. The base frame 101 is placed or fixed to the ground, and the sub-frame 103 and the main frame 102 are both mounted on the base frame 101. In the horizontal direction, the bottom of the sub-frame 103 is opposite to that of the main frame 102.

[0069] The motion component 2 is mounted on the main frame 102 and can move up and down along the main frame 102 to achieve lifting and lowering. Weight components such as barbell plates are mounted on the motion component 2, and the training weight provided by the motion component 2 can be adjusted by adding or removing the weight components mounted on the motion component 2.

[0070] During leg press training, the user sits at the bottom of the main frame 102, with their back against the secondary frame 103. They repeatedly push and bend their legs upwards, raising or lowering the motion component 2, thus training leg strength. During squat training, the user places their feet on the secondary frame 103, leans against the main frame 102, and places the motion component 2 against their shoulders. They repeatedly push and bend their legs downwards, using their shoulders to push and lower the motion component 2, raising and lowering it, thus training leg and glute strength.

[0071] The limiting assembly 3 includes a drive base 301, an operating lever 302, a limiting seat 303, and a limiting rod 304. The drive base 301 is hinged to the main frame 102, allowing it to rotate around the hinge point. The operating lever 302 has an operating part 3021 and a driving part 3022, with the driving part 3022 connected to the operating part 3021. The driving part 3022 is connected to the drive base 301, and the operating part 3021 extends to one side of the main frame 102. The limiting seat 303 is hinged to the main frame 102, allowing it to rotate around the hinge point. The drive base 301 and the limiting seat 303 are connected via a transmission link 305, and the limiting rod 304 is disposed on the limiting seat 303.

[0072] The drive unit 3022 is a rod, coaxially fixedly connected to the drive base 301. The user holds and pushes or pulls the operating unit 3021, which causes the operating lever 302 to rotate around the drive unit 3022 as a pivot, and the drive base 301 rotates accordingly. The rotating drive base 301 drives the limiting seat 303 to rotate through the transmission link 305. The limiting rod 304 rotates with the limiting seat 303, thereby allowing the limiting rod 304 to rotate between a first position and a second position.

[0073] The moving part 2 is located on the upper side of the main frame 102, and the limiting component 3 is located on the lower side of the main frame 102. The operating part 3021 extends to one side of the moving part 2 so that the user can hold the operating part 3021. When the user pushes or pulls the operating lever 302, the limiting lever 304 flips downward and moves to the first position. At this position, the limiting lever 304 is located on the side of the moving part 2 closest to the main frame 102, so that the limiting lever 304 leaves the movement trajectory of the moving part 2. The limiting lever 304 will not obstruct the raising and lowering of the moving part 2, and the user can perform resistance training normally. When the user pushes or pulls the operating lever 302, the limiting lever 304 flips upward and moves to the second position. The limiting lever 304 moves towards the moving part 2 and onto the moving trajectory of the moving part 2, so that the limiting lever 304 is aligned with the moving part 2 in the moving direction of the moving part 2. The moving part 2 can then descend and land on the limiting lever 304, so that the limiting lever 304 is attached to the middle of the end face of the moving part 2 near the sub-frame 103, thereby preventing the moving part 2 from falling further and avoiding injury to the user due to exhaustion caused by the heavy moving part 2.

[0074] This structural design enables the limiting component 3 to form a single-handle linkage multi-bar mechanism. Both the rotating limiting seat 303 and the drive seat 301 act as connecting rods, with the transmission link 305 connecting the limiting seat 303 and the drive seat 301. The operating lever 302 serves as the handle. Users only need to push or pull the operating lever 302 to move the limiting lever 304 from one side of the main frame 102 to the other to limit and stop the movement of the moving part 2, or to remove the obstruction. The operation is simple, allowing users to easily prevent the moving part 2 from falling when exhausted, eliminating training resistance and preventing injury. Furthermore, when the limiting lever 304 is in operation, it moves to the middle of the moving part 2, providing stable support and maintaining its balance, ensuring the stability and reliability of the limiting stop.

[0075] See also in this application. Figures 4 to 6 The main frame 102 is provided with a mounting base 306, and a limiting seat 303 is hinged to the mounting base 306. A first mounting post 307 is provided on the limiting seat 303, and a second mounting post 308 is provided on the mounting base 306. An elastic element 309 is provided between the first mounting post 307 and the second mounting post 308.

[0076] When the elastic element 309 is an elastic tension element, during the process of the push-pull operating lever 302 moving the limiting lever 304 from the first position to the second position, the drive seat 301 rotates, and the first mounting post 307 moves along an arc trajectory, increasing the distance between the first mounting post 307 and the second mounting post 308. The elastic element 309 is then stretched, generating elastic force. The moving part 2 falls onto the limiting lever 304 in the second position. Under the pressure of the moving part 2, the limiting lever 304 remains in the second position, continuously limiting and stopping the moving part 2. When the user pushes the moving part 2 upwards, the moving part 2 moves away from the limiting lever 304, and the elastic force of the elastic element 309 pulls the limiting seat 303, thereby pulling the limiting lever 304 back from the second position to the first position.

[0077] When the elastic element 309 is an elastic compression element, during the process of the push-pull operating lever 302 moving the limiting lever 304 from the first position to the second position, the drive seat 301 rotates, and the first mounting post 307 moves along an arc trajectory, reducing the distance between the first mounting post 307 and the second mounting post 308. The elastic element 309 is compressed, generating elastic force. The moving part 2 falls onto the limiting lever 304 in the second position. Under the pressure of the moving part 2, the limiting lever 304 remains in the second position, continuously limiting and stopping the moving part 2. When the user pushes the moving part 2 upward, the moving part 2 moves away from the limiting lever 304, and the elastic force of the elastic element 309 pushes the limiting seat 303, thereby pulling the limiting lever 304 back from the second position to the first position.

[0078] To improve the compactness of the structure, the limiting seat 303 is disposed within the mounting base 306, and the first mounting post 307 is movably connected in the arc-shaped groove 310 provided in the mounting base 306, so that the first mounting post 307 extends out of the mounting base 306 and connects to the elastic member 309 located on the outside of the mounting base 306. This is to further protect the elastic member 309.

[0079] This structural design allows the limiting member to automatically return to the first position under the drive of the elastic member 309 when the user pushes the moving part 2 upward for impedance training. This eliminates obstruction to the raising and lowering of the moving part 2, eliminating the need to operate the lever 302, simplifying the operation process and improving ease of use. Furthermore, when the lever 302 is not operated, the elastic member 309 can limit the movement of the limiting seat 303, keeping the limiting rod 304 in the first position. This prevents the limiting rod 304 from moving onto the movement trajectory of the moving part 2, thus avoiding obstruction of the raising and lowering of the moving part 2 during normal training and ensuring that impedance training proceeds normally.

[0080] See also in this application. Figures 2 to 6The main frame 102 includes a support beam 1021 and guide shafts 1022. Two guide shafts 1022 are disposed on the support beam 1021. Both guide shafts 1022 are parallel to the support beam 1021 and are respectively disposed on both sides of the support beam 1021, such that the support beam 1021 is located between the two guide shafts 1022. Two guide sleeves 201 are respectively disposed on both sides of the moving component 2, and the two guide sleeves 201 are respectively fitted onto the two guide shafts 1022. Through the cooperation between the two sets of guide sleeves 201 and the guide shafts 1022, the two sides of the moving component 2 slide along the guide shafts 1022, achieving smooth lifting and lowering of the moving component 2.

[0081] Since the support beam 1021 is located between the two guide shafts 1022, and the two guide shafts 1022 are respectively passed through the two guide sleeves 201 on both sides of the moving component 2, the support beam 1021 is aligned with the central axis of the moving component 2. The drive seat 301 and the limiting seat 303 are both set on the support beam 1021, so that the limiting rod 304 is aligned with the central axis of the moving component 2, ensuring that the limiting rod 304 abuts against and supports the middle of the moving component 2. The limiting rod 304 is U-shaped. When the limiting rod 304 moves to the second position, the two ends of the limiting rod 304 are respectively located on both sides of the support beam 1021, so that the support beam 1021 enters the area surrounded by the limiting rod 304. The limiting rod 304 surrounds the support beam 1021 to a certain extent. The two ends of the limiting rod 304 on the same side move onto the movement trajectory of the moving component 2, so that the limiting rod 304 evenly supports the moving component 2 through the two ends.

[0082] This structural design makes the support base a single-beam structure composed of support beam 1021. Compared with the existing technology that uses two beam structures and slides the moving part 2 between the two beam structures, the single-beam structure is simpler, has lower manufacturing cost and maintenance difficulty, and occupies less space. The design of the guide shaft 1022 and guide sleeve 201 allows the moving part 2 to slide smoothly along the guide shaft 1022. The single-beam structure of the support base centers the support beam 1021, and the limiting seat 303 is set on the support beam 1021 so that the limiting rod 304 can also be centered, making it easy for the limiting rod 304 to move to the second position and align with the middle of the moving part 2, ensuring stable support for the moving part 2. The U-shaped structure of the limiting rod 304 further ensures that it symmetrically contacts both sides of the middle of the moving part 2, achieving stable limiting and support for the moving part 2.

[0083] See also in this application. Figure 2 , Figure 3 and Figure 5The main frame 102 further includes two limiting frames 1023, which are respectively disposed at both ends of the support beam 1021, thereby limiting the range of motion of the moving part 2 to be raised and lowered between the two limiting frames 1023. The two ends of the guide shaft 1022 are respectively disposed on the two limiting frames 1023, so that the limiting frames 1023 provide mounting and fixing for the guide shaft 1022.

[0084] This structural design effectively limits the movement range of the moving part 2. The lower limiting frame 1023 blocks the moving part 2, preventing it from falling excessively and colliding with the base frame 101, the ground, or hitting the user. The upper limiting frame 1023 blocks the moving part 2, preventing it from rising excessively and detaching from the main frame 102, thus preventing it from falling and hitting the ground, the base frame 101, or the user, and avoiding damage to the equipment or injury to the user. In addition, the connection design between the limiting frame 1023 and the support beam 1021 not only provides installation and fixation for the guide shaft 1022, but also forms a robust frame structure, making the entire main frame 102 structure more stable and improving the overall stability of the equipment.

[0085] See also in this application. Figures 2 to 6 The support beam 1021 is inclined, and the moving part 2 is attached to the upper surface of the support beam 1021, so that the moving part 2 can slide on the surface of the support beam 1021 during the lifting and lowering process.

[0086] This structural design allows the user's legs or back to rest diagonally against the support beam 1021 when performing leg presses or squats. Compared to having the legs vertical or the upper body upright, when pushing off or kicking to raise the motion component 2, there is no need to use additional force to keep the legs or upper body vertical. The user can concentrate more force on the leg push to resist the load on the motion component 2, improving the user experience and ensuring training effectiveness. In addition, the motion component 2 slides above the support beam 1021, allowing the support beam 1021 to provide a certain degree of support for the motion component 2 from top to bottom, improving the stability of the motion component 2 during training.

[0087] See also in this application. Figures 1 to 5The main frame 102 further includes a diagonal brace 1024. The diagonal brace 1024 is inclined, with one end connected to the support beam 1021 and the other end connected to the base frame 101. A counterweight storage rod 1025 is provided on the diagonal brace 1024 for installing counterweight components. This structural design allows the diagonal brace 1024 to support and reinforce the support beam 1021, enhancing the overall structural strength of the main frame 102 and improving the durability of the equipment. The counterweight storage rod 1025 on the diagonal brace 1024 can store counterweight components, making full use of the equipment space and facilitating the movement of counterweight components to or from the moving part 2 for storage. This makes the installation and adjustment of counterweight components more flexible, meeting the training needs of different users.

[0088] See also in this application. Figure 3 and Figure 5 The operating unit 3021 is equipped with a lower handle 3021-1 and an upper handle 3021-2. One end of the lower handle 3021-1 is connected to the drive unit 3022. A seat 5 is provided at the bottom of the main frame. The other end of the lower handle 3021-1 extends away from the upper surface of the seat 5 and connects to one end of the upper handle 3021-2, so that the user sitting on the seat 5 at the bottom of the main frame 102 can hold the lower handle 3021-1 during leg press training. The end of the upper handle 3021-2 away from the lower handle 3021-1 extends towards the moving part 2, so that the user standing and leaning against the main frame 102 can hold the upper handle 3021-2 during squat training.

[0089] This structural design allows users to easily grip the control lever 302 in both training modes, whether standing or sitting. Furthermore, the extended upper handle 3021-2 accommodates users of different heights and body types, allowing different users to grip the control lever 302 from different positions, further enhancing the device's versatility.

[0091] The movable seat 202, serving as the main structure of the moving component 2, is mounted on the support beam 1021. When the moving component 2 has guide sleeves 201 on both sides, the guide sleeves 201 are mounted on the movable seat 202. A counterweight rod 205 is mounted on the movable seat 202 for mounting counterweight components. Two shoulder supports 203 are respectively mounted on both sides of the movable seat 202. The upper foot pedal 204 is hinged to the movable seat 202, and a stop block 206 is mounted on the upper foot pedal 204.

[0092] During leg press training, when the upper foot pedal 204 is flipped upwards to be perpendicular to the moving seat 202, the stop block 206 is attached to the moving seat 202. When the user pushes upwards with their legs, the stop block prevents the upper foot pedal 204 from flipping upwards further, so that the pushing force of the user's legs resists the resistance generated by the counterweight components, pushing the moving seat 202 upwards.

[0093] When performing squat training, the upper foot pedal 204 is flipped downwards to be parallel to the moving seat 202. The user leans against the upper foot pedal 204, and both shoulders are placed against the shoulder support 203 from bottom to top, so that the user pushes down with his legs to resist the resistance generated by the counterweight components and pushes the moving seat 202 upwards through his shoulders.

[0094] This structural design allows the upper foot pedal 204 to be folded or unfolded by flipping, enabling switching between leg press and squat functions, thus improving the equipment's versatility. Furthermore, the stop block 206 effectively prevents the upper foot pedal 204 from flipping upwards, ensuring that it remains stably vertical during leg press training and guaranteeing user safety.

[0095] See also in this application. Figures 1 to 3 as well as Figure 5 The leg press squat machine further includes a backrest 4. A lower foot pedal 104 is provided on the upper surface of the sub-frame 103, and a seat cushion 5 is provided at the bottom of the main frame 102, located on the side of the main frame 102 near the base frame 101. The backrest 4 is detachably mounted on either the upper foot pedal 204 or the lower foot pedal 104.

[0096] The backrest 4 can be detachably connected to the upper foot pedal 204 or the lower foot pedal 104 via fasteners, magnets, or other connectors. When performing leg press training, the backrest 4 is fixed to the lower foot pedal 104, and the user sits on the seat cushion 5 with their back against the backrest 4. When performing squat training, the study notebook is fixed to the upper foot pedal 204, and the user's back is against the backrest 4.

[0097] The structural design, with its detachable backrest, allows it to be mounted on either the upper foot pedal 204 or the lower foot pedal 104, adapting to different training modes and improving the flexibility of the equipment. This provides more comfortable support for the user in each training mode and also prevents the user from getting their clothes dirty by touching the foot pedals.

[0098] See also in this application. Figures 1 to 3 as well as Figure 5The bottom end of the subframe 103 is hinged to the base frame 101, allowing the subframe 103 to rotate and change its tilt angle, thereby altering the angle of the user's back when pedaling backwards. A telescopic link 105 is provided between the top of the subframe 103 and the base frame 101. Both ends of the telescopic link 105 are hinged, and by changing the length of the telescopic link 105, the tilt angle of the base can be adjusted while maintaining stable support for the base.

[0099] The telescopic link 105 can adopt a sleeve structure, including an inner tube and an outer tube. The outer tube is fitted over the inner tube, and the length of the telescopic link 105 can be changed by extending or retracting the inner tube. Multiple positioning holes are axially spaced on the outer tube. A pin inserted into the inner tube passes through one of these positioning holes. By changing the positioning hole connected to the pin, the telescopic link 105 is positioned and fixed at the corresponding length, thus providing stable support for the subframe 103. The telescopic link 105 can also employ components capable of changing length, such as a hydraulic rod.

[0100] This structural design allows the subframe 103 to be adjusted according to the user's body shape and posture, changing the tilt angle of the subframe 103 and improving the flexibility of the equipment.
