Description

Technical Field

[0001] This utility model relates to the technical field of fitness equipment storage devices, and in particular to a cycling cabinet for storing and using cycling trainers. Background Technology

[0002] Existing cabinet-style fitness equipment, such as the patented solution with publication number "CN2230175Y," uses a design where the exercise bike is fixed to the side wall of the cabinet, and the equipment is unfolded and stored by flipping and opening the side wall. While this type of solution aims to save space, it suffers from two fundamental drawbacks:

[0003] Firstly, because the entire weight of the exercise bike is applied directly to the sidewalls, the weight of the equipment creates a huge resistance torque when the sidewalls rotate and unfold around the bottom hinge axis. This torque amplifies significantly with the increase in sidewall length, making opening and closing operations extremely difficult. Especially for exercise equipment weighing over 15 kg, ordinary users find it difficult to independently switch between states, severely reducing the product's practicality. This defect stems from a flawed mechanical design—the movable door panel, which should not be used as a primary load-bearing component, is forced to bear the entire load of the equipment, violating basic principles of mechanical structure design.

[0004] Secondly, in its stored state, the equipment is suspended inside the cabinet via the side walls. This suspension support causes the hinged structure to be subjected to alternating stresses in directions other than those designed for it. The vibration energy generated during equipment operation cannot be effectively dissipated and is directly transmitted to the side wall connections. This continuous stress concentration accelerates metal fatigue, leading to structural damage such as hinge deformation and cabinet cracking, significantly shortening the product's lifespan. The crux of the problem lies in the inappropriate support method: the lack of rigid support points when moving parts bear static loads inevitably leads to reliability degradation. Summary of the Invention

[0005] To address the aforementioned issues, the present invention aims to provide a cycling cabinet for storing and using cycling trainers, which offers advantages such as optimized force transmission path, reduced operating resistance, and improved structural stability and adaptability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This application provides a cycling cabinet for storing and using cycling training devices, the technical solution of which includes:

[0008] • Cabinet;

[0009] • The lower cabinet door is hinged to the bottom of the cabinet body;

[0010] • Arc-shaped guide rails installed on the bottom plate of the cabinet;

[0011] • An extended guide rail is installed on the inner wall of the lower cabinet door, which connects with the curved guide rail when the lower cabinet door is fully opened;

[0012] • A riding platform that can slide along curved guide rails and extended guide rails;

[0013] • The rotating mechanism, which connects the cycling trainer and the cycling platform, is configured to independently adjust the horizontal and vertical orientation of the cycling trainer relative to the cycling platform;

[0014] • The curved guide rail guides the cycling platform to slide, enabling the cycling trainer to change its spatial position between the depth and width directions of the cabinet:

[0015] o Storage state: The cycling platform is moved into the cabinet, and the cycling trainer is positioned vertically along the width of the cabinet;

[0016] o Usage status: The cycling platform is pulled out to the end of the extended guide rail, and the cycling trainer is in a horizontal position along the depth of the cabinet.

[0017] This technical solution reconstructs the mechanical transmission path between motion guidance and gravity bearing, transferring the weight of the cycling trainer in its stored state from the movable door panel to the cabinet base. The cabinet serves as the main load-bearing structure, with the lower cabinet door only guiding the sliding of the cycling platform, not providing gravity support in the stored state. The connection design of the curved guide rail and the extended guide rail creates a continuous sliding path between the cabinet base and the lower cabinet door, ensuring smooth spatial repositioning of the cycling trainer and preventing the lower cabinet door from bearing vertical loads in the stored state. The rotating mechanism independently adjusts the orientation of the cycling trainer, ensuring it is vertically against the cabinet side wall when stored to save space, and horizontally unfolded to form a stable support surface when in use. Through the linkage between the sliding of the cycling platform on the rails and the rotating mechanism, the cycling trainer's spatial transformation between the inside and outside of the cabinet is achieved. The cycling trainer, through the cycling platform structure and the curved and extended guide rails, enables a flip-and-store function, solving the problem of inconvenient storage and excessive space requirements encountered by users when using the cycling trainer. Furthermore, the entire adjustment process is convenient and effortless, and the lower cabinet door is no longer under stress when folded up.

[0018] Furthermore, this application also proposes that an auxiliary slide rail be provided on the inner wall of the lower cabinet door;

[0019] The sliding platform is positioned on an auxiliary slide rail.

[0020] The cycling platform is mounted on a sliding platform via a slewing mechanism;

[0021] • When the sliding platform moves along the auxiliary slide rail, the riding platform slides synchronously along the arc-shaped guide rail and the extended guide rail, and rotates adaptively through the lateral rotation mechanism.

[0022] This solution utilizes an auxiliary slide rail inside the lower cabinet door to form a composite track system, decomposing the sliding of the cycling platform into the coordinated movement of the auxiliary slide rail and the curved / extended guide rail. The auxiliary slide rail regulates the direction and path of the sliding platform's movement, while the cycling platform achieves spatial position changes under the guidance of the curved and extended guide rails. The combination of the lateral rotation mechanism and the sliding platform allows the cycling platform to rotate around the lateral rotation axis while sliding along the curved track, ensuring that the cycling trainer maintains its predetermined trajectory throughout spatial transitions.

[0023] Furthermore, this application also proposes that there are two auxiliary slide rails that are distributed in parallel on both sides of the extended guide rail;

[0024] • The two ends of the sliding platform are connected to auxiliary slide rails on both sides respectively.

[0025] Furthermore, this application also proposes that a limit track be provided on the inner wall of the lower cabinet door, and that multiple insertion holes be provided along its length;

[0026] • The sliding platform is equipped with a limit lock, which can be plugged into any socket to lock the position of the sliding platform, making it suitable for cycling trainers of different lengths.

[0027] This technical solution constructs a multi-level positioning mechanism by setting a limiting track with continuous insertion holes on the inner wall of the lower cabinet door, in conjunction with an adjustable locking device on the sliding platform. The insertion hole array design along the length of the limiting track provides discrete fixed nodes, enabling the sliding platform to achieve mechanical locking at any selected position. The insertion and engagement of the limiting lock with the insertion holes forms a rigid connection, effectively eliminating the risk of displacement of the sliding platform during equipment use. By selecting different insertion hole positions for locking, the positioning requirements of cycling trainers of different sizes can be precisely adapted, ensuring that the platform position matches the length of the trainer when the equipment is unfolded, avoiding structural interference caused by the platform being suspended due to excessive length or too short a length. This dual positioning structure retains the degree of freedom for position adjustment of the sliding platform, while meeting the positioning needs of cycling trainers of different lengths through discrete locking, thus resolving the compatibility contradiction between variable-length equipment and fixed guide tracks.

[0028] Furthermore, this application also proposes that the sliding platform includes:

[0029] • The first platform section is movable and mounted on the auxiliary slide rail;

[0030] • The second platform section is connected to the first platform section via a hinge;

[0031] The cycling platform is located on the second platform section via a lateral rotation mechanism;

[0032] • In the storage state: The second platform is located inside the cabinet, the first platform is located in the lower cabinet door, and the hinge axis is inside the rotation axis of the lower cabinet door, so that the lower cabinet door can be closed.

[0033] This technical solution constructs a foldable composite support structure by decomposing the sliding platform into a hinged first platform section and a second platform section. The first platform section moves along an auxiliary slide rail to bear the basic displacement function, while the second platform section achieves relative rotation with the first platform section through a hinge, allowing the riding platform to adjust its spatial posture relative to the second platform section under the action of a lateral rotation mechanism. In the stored state, the second platform section moves into the cabinet to form a rigid support. When the lower cabinet door closes, the hinge axis of the first platform section is located inside the rotation axis of the lower cabinet door. This layout avoids interference between the hinge and the cabinet frame, and shortens the lever arm length of the extended part of the first platform section by moving the hinge fulcrum inward, thereby reducing the motion resistance when the lower cabinet door closes. This dual-platform structure, through spatial division and motion decoupling, ensures the stability of the riding trainer during storage while achieving physical compatibility between the closing action of the lower cabinet door and the platform storage path.

[0034] Furthermore, this application proposes a gap between the inner end of the extended guide rail and the outer end of the curved guide rail, allowing the lower cabinet door to open and close relative to the cabinet body. This technical solution decouples the opening and closing action of the lower cabinet door from the track structure by setting a gap between the extended guide rail and the curved guide rail. The physical isolation of the gap prevents rigid contact between the two tracks when the door flips, allowing the lower cabinet door to fully conform to the cabinet body when closed and freely rotate to a predetermined angle when opened. The size design of this gap must simultaneously meet two functional requirements: on the one hand, it must ensure the continuity of the riding platform when sliding between the tracks; on the other hand, it must leave necessary space for the rotational movement of the door hinges. This discontinuous track design breaks through the traditional mindset that guide mechanisms must maintain track continuity, fundamentally eliminating the mechanical conflict between the door movement and the track structure while ensuring the controllable trajectory of equipment storage and unfolding.

[0035] Furthermore, this application also proposes that the riding platform is equipped with rollers on both sides at the lower end;

[0036] Both the extended guide rail and the curved guide rail are parallel double-rail structures;

[0037] • The riding platform has at least one roller positioned between the two rails to form an anti-derailment guide.

[0038] This technical solution achieves anti-derailment protection for sliding guides through structural co-design. Rollers are installed on both sides of the lower end of the riding platform, forming a symmetrical support structure to ensure balanced load distribution. The extended guide rail and the arc-shaped guide rail adopt a parallel double-rail structure, with the distance between the two rails forming a physical constraint space. At least one roller is embedded between the two rails, using the sidewalls of the rails to form a mechanical limit, effectively suppressing the lateral offset tendency generated when the riding platform slides. This nested cooperation between the rollers and the double rails maintains the degree of freedom of sliding while eliminating the possibility of derailment through geometric constraints. It is particularly suitable for riding equipment that requires frequent state switching, ensuring precise and controllable movement trajectory.

[0039] Furthermore, this application also proposes that an upper cabinet door is hinged to the top of the cabinet;

[0040] • Gas spring assemblies are installed between the upper and lower cabinet doors and the cabinet body;

[0041] • When closed, the upper and lower cabinet doors together seal the cabinet opening.

[0042] Furthermore, this application also proposes that a removable or flip-up table is provided at the middle height inside the cabinet;

[0043] • When stowed: The tabletop can be removed or flipped over to avoid obstructing the cycling trainer.

[0044] This technical solution addresses the structural interference issue within the cabinet's interior space when it's folded up by incorporating a detachable or flip-up tabletop. The tabletop, positioned at a mid-height level within the cabinet, functions as a shelf or work surface in its normal state. When folded up, its spatial position can be altered through disassembly or flipping, providing space for the cycling trainer. Specifically, the detachable tabletop allows users to easily remove it as needed, eliminating the obstruction of the trainer's folded position by rigid components. The flip-up tabletop adjusts its orientation through rotation, achieving space avoidance without complete removal. Both methods change the relative position of the tabletop and the trainer, preventing physical contact when folded up, thus reducing the path of vibration energy transmission from the equipment to the cabinet and mitigating the risk of stress concentration caused by structural interference.

[0045] Furthermore, this application proposes integrating a multimedia function module within the cabinet, including a power supply interface and a display device mounting structure. This technical solution constructs a complete equipment support system by integrating the multimedia function module within the cabinet. The power supply interface directly addresses the power supply needs of external electronic devices, avoiding the safety hazards associated with user-installed wiring through a built-in power system. The innovative design of the display device mounting structure, with its pre-set standardized interfaces and support frame, allows for quick and stable installation and removal of various displays, satisfying both the visual interaction needs during training and ensuring efficient space utilization when stored. The synergistic effect of these two technical features breaks through the limitations of traditional fitness cabinets' single storage function, forming a composite solution integrating equipment storage, power supply, and human-computer interaction.

[0046] As can be seen from the above, the cycling cabinet for storing and using cycling trainers provided in this application, along with its sliding platform and rotating mechanism, achieves spatial position conversion of the cycling trainer through the sliding cooperation between the arc-shaped guide rail and the cycling platform. Combined with the rotating mechanism, the device orientation can be adjusted independently, solving the problems of hinge wear, vibration transmission, and unstable center of gravity caused by the gravity lever effect in traditional solutions. It has the advantages of optimizing the force transmission path, reducing operating resistance, and improving structural stability and adaptability. Attached Figure Description

[0052] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0053] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0054] Furthermore, the terms "first" and "second" 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. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0055] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., 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 mechanical connection or an electrical 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 according to the specific circumstances.

[0056] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0057] In existing technologies, cabinet-style fitness equipment typically fixes the exercise bike entirely to the side wall of the cabinet, unfolding and storing it by flipping the side wall. This design forces the movable door panel to simultaneously serve as a guide for movement and a support for gravity, resulting in laborious opening and closing operations and a tendency for structural damage. When the side wall is unfolded, the weight of the equipment creates excessive resistance torque, making it difficult for the user to operate; in the stored state, the suspended support method subjectes the hinges to stress in directions other than those designed for it, easily leading to metal fatigue and structural damage.

[0058] To solve the above problems, such as Figure 1-5 As shown, this application proposes a device including a cabinet 1, a lower cabinet door 2 hinged to the bottom of the cabinet 1, an arc-shaped guide rail 3 on the cabinet base plate 10, an extended guide rail 4 on the inner wall of the lower cabinet door 2, a cycling platform 5 sliding along the rails, and a rotating mechanism 6 connecting the cycling trainer 22 and the platform 5. The arc-shaped guide rail 3 connects with the extended guide rail 4, guiding the cycling platform 5 to slide and realize the spatial transformation of the device between the depth and width directions of the cabinet 1. When stored, the platform 5 is moved into the cabinet 1, and the device 22 is in a vertical position in the width direction; when in use, the platform 5 is pulled out to the end of the rails, and the device 22 is in a horizontal position in the depth direction.

[0059] The curved guide rail 3 refers to a continuous slide with a radius of curvature set on the cabinet base plate 10. It can be a regular or irregular arc, and its curvature design ensures that the sliding trajectory of the platform 5 matches the space of the cabinet 1. The extended guide rail 4 refers to a straight rail installed on the inner wall of the lower cabinet door 2. When the lower cabinet door 2 is opened to the horizontal position, it connects with the end of the curved guide rail 3 to form a continuous path. The riding platform 5 refers to the movable base that supports the riding trainer 22. Specifically, it can be implemented using a riding training seat with resistance, and its bottom moves smoothly along the rail. The rotating mechanism 6 refers to a multi-degree-of-freedom joint connecting the riding trainer 22 and the riding platform 5, which can independently adjust the pitch angle of the riding platform 5.

[0060] When the device 22 needs to be stored, the riding platform 5 slides into the cabinet 1 along the extended guide rail 4, changes its direction of movement via the curved guide rail 3, and finally enters the cabinet 1 completely. During this process, the rotating mechanism 6 adjusts the device 22 to a vertical position, close to the side wall of the cabinet 1. The weight of the device 22 is transferred to the cabinet bottom plate 10 through the riding platform 5, and the lower cabinet door 2 does not bear a vertical load when closed. In use, the lower cabinet door 2 is opened to a horizontal position so that the extended guide rail 4 aligns with the curved guide rail 3, and the riding platform 5 slides outward along the rail to the end. The rotating mechanism 6 simultaneously adjusts the device 22 to a horizontal position, forming a stable riding support surface.

[0061] This solution completely separates the two functions by having the cabinet base plate 10 bear the weight and the track system guide the movement. The lower cabinet door 2 only serves as an extension of the track and does not bear the weight of the equipment 22 during opening and closing, significantly reducing operational resistance. The weight of the equipment 22 is transferred to the main structure of the cabinet 1 through a rigid platform, eliminating stress concentration in the moving parts. Through the above technical solution, this application achieves labor-saving operation of storing and unfolding the equipment 22, allowing ordinary users to complete the state transition with one hand. The main structure of the cabinet 1 bears the static load, effectively preventing hinge deformation and cabinet cracking. The continuous connection of the track system ensures smooth position transition of the equipment 22, and the rotating mechanism 6 provides multi-angle adjustment to adapt to different usage needs. The equipment 22 is stably fixed in the stored state, eliminating the impact of operating vibrations on moving parts and extending the overall service life.

[0062] In a further embodiment, an auxiliary slide rail 11 is provided on the inner wall of the lower cabinet door 2. The sliding platform 12 is movably mounted on the auxiliary slide rail 11, and the riding platform 5 is mounted on the sliding platform 12 via a horizontal rotation mechanism 13. The sliding platform 12 moves along the auxiliary slide rail 11.

[0063] When in motion, the riding platform 5 slides synchronously along the arc-shaped guide rail 3 and the extended guide rail 4, and rotates adaptively through the lateral rotation mechanism 13.

[0064] The auxiliary slide rail 11 refers to a linear track parallel to both sides of the extended guide track 4, used to guide the sliding platform 12 to move along a predetermined path, distributing the load transmitted by the riding platform 5 through the double-track structure. The sliding platform 12 is a load-bearing structure connected to the auxiliary slide rails 11 on both ends, which evenly transmits the weight of the riding platform 5 to the lower cabinet door 2 during its movement, avoiding local stress concentration. The lateral rotation mechanism 13 is a hinged device that allows the riding platform 5 to rotate around the vertical axis. Specifically, it can use a thrust bearing in conjunction with a rotating shaft structure, allowing the riding platform 5 to automatically adjust its horizontal orientation to adapt to changes in track curvature during sliding. Specifically, when the sliding platform 12 moves along the auxiliary slide rail 11, the riding platform 5 is displaced under the constraints of the arc-shaped guide track 3 and the extended guide track 4. The lateral rotation mechanism 13 compensates for the difference in the direction of movement of the riding platform 5 at different positions on the arc-shaped track 3 by freely rotating around the vertical axis. The double-sided support structure of the sliding platform 12 decomposes the weight of the riding platform 5 into two symmetrical support reactions, eliminating the torque caused by the single-sided slide rail load. The auxiliary slide rail 11 and the arc-shaped guide rail 3 form a composite track system with spatial intersection. The movement trajectory of the cycling platform 5 is formed by the superposition of the linear displacement of the sliding platform 12 and the rotational displacement of the lateral rotation mechanism 13, ensuring that the cycling trainer 22 maintains the predetermined posture during spatial transformation.

[0065] In a further embodiment, two auxiliary slide rails 11 are arranged parallel to each other on both sides of the extended guide rail 4, and the two ends of the sliding platform 12 are respectively connected to the two auxiliary slide rails 11. The two auxiliary slide rails 11 arranged parallel to each other on both sides of the extended guide rail 4 mean that the two slide rails are arranged with the extended guide rail 4 as the center, forming a symmetrical guiding constraint. The two ends of the sliding platform 12 are respectively connected to the two auxiliary slide rails 11, meaning that the edges of the platform 12 on both sides are rigidly connected to the corresponding slide rails. This can be achieved using a sliding pair structure of slider and slide rail, ensuring that the sliding platform 12 is subjected to synchronous force on both sides when it moves. When the sliding platform 12 moves along the auxiliary slide rails 11, the two slide rails simultaneously provide guiding constraints, and the lateral torque generated by the movement of the riding platform 5 is jointly canceled by the two slide rails, preventing a single slide rail from bearing the entire load. The sliding platform 12 maintains a horizontal posture through the rigid connection at both ends, and the riding platform 5 rotates adaptively under the action of the lateral rotation mechanism 13, ensuring the accuracy of the movement trajectory along the arc-shaped guide rail 3 and the extended guide rail 4. The symmetrical distribution of the two slide rails ensures that the load is evenly transferred to the inner wall of the lower cabinet door 2, eliminating local stress concentration.

[0066] like Figure 5 As shown, a limiting track 14 is provided on the inner wall of the lower cabinet door 2, with multiple insertion holes 141 along its length. A limiting lock 15 is provided on the sliding platform 12, which can be inserted into any of the insertion holes 141 to lock the position of the sliding platform 12. The limiting track 14 refers to a track structure extending along the length of the inner wall of the lower cabinet door 2, which can be implemented using a metal profile with perforations and grooves. Its function is to provide multi-level positioning references for the sliding platform 12. The limiting track 14 is constructed parallel to the auxiliary slide rail 11 and the extended guide rail 4. The insertion holes 141 are holes spaced apart along the length of the limiting track 14, which can be implemented using equidistant circular through holes. Their function is to provide discrete fixed nodes for the lock. The limiting lock 15 is a mechanical locking device installed on the sliding platform 12, which can be implemented using a spring pin structure. Its function is to form a rigid constraint through insertion and engagement with the insertion holes 141.

[0067] As the sliding platform 12 moves along the auxiliary slide rail 11, the limit lock 15 moves synchronously with the platform. By selecting different positions...

[0068] The locking device is inserted into the designated socket 141, allowing the sliding platform 12 to be mechanically locked at any selected position. Differences in the length of the cycling trainer 22 are compensated for by adjusting the insertion position. For example, when the device 22 is longer, the locking device is inserted into the socket 141 near the end of the track, allowing the platform to extend further outward; when the device 22 is shorter, the socket 141 near the beginning of the track is selected for locking. After insertion, the locking device and the socket 141 form an interference fit, effectively suppressing vibration and displacement of the platform during operation.

[0069] This solution, through the cooperation of discrete sockets 141 and adjustable locking devices, enables the same sliding platform 12 to accommodate cycling trainers 22 of various lengths, achieving rigid locking while retaining position adjustment functionality. Through the above technical solution, this application solves the problem of unstable positioning of the sliding platform 12 caused by differences in the length of the devices 22. The multi-level socket 141 design allows the platform position to be flexibly adjusted according to the device size. The insertion and engagement of the locking device with the sockets 141 forms a reliable mechanical lock, avoiding the risk of displacement caused by vibration or load changes during device use, and ensuring stable support and precise positioning of cycling trainers 22 of different lengths.

[0070] like Figure 2 and 5 As shown, the sliding platform 12 includes a first platform section 16 and a second platform section 17. The first platform section 16 is movably mounted on the auxiliary slide rail 11, and the second platform section 17 is connected to the first platform section 16 via a hinge. The riding platform 5 is mounted on the second platform section 17 via a horizontal rotation mechanism 13. In the storage state, the second platform section 17 is located inside the cabinet 1, and the first platform section 16 is located in the lower cabinet door 2. The hinge axis is located inside the rotation axis of the lower cabinet door 2.

[0071] The first platform section 16 provides basic displacement for the overall structure by moving along the auxiliary slide rail 11. The second platform section 17 is the support component directly connected to the riding platform 5, which can be implemented using a steel plate structure with a hinge seat, forming a rotating pair with the first platform section 16 through a hinge. The hinge axis being located inside the rotation axis of the lower cabinet door 2 means that the rotation center of the hinge is located in the inner area of ​​the connection between the hinge point of the lower cabinet door 2 and the cabinet body 1. This layout shortens the lever arm length of the extended portion of the first platform section 16.

[0072] When the cycling trainer 22 needs to be stored, the second platform 17 moves with the sliding platform 12 into the cabinet 1 to form a rigid support, and the cycling platform 5 is adjusted to a vertical position via the horizontal rotation mechanism 13. At this time, the first platform 16 moves towards the cabinet 1 as the lower cabinet door 2 closes. Since the hinge axis is located inside the rotation axis of the lower cabinet door 2, the folding angle of the first platform 16 and the second platform 17 automatically adapts to the internal space of the cabinet 1, avoiding interference with the cabinet frame. This folding structure allows the first platform 16 to only undergo a small displacement during the closing process, significantly reducing the resistance torque generated by its extended portion and ensuring smooth closing of the lower cabinet door 2. At the same time, the second platform 17 forms a three-point support structure inside the cabinet 1, locking the vertical position of the cycling platform 5 through the horizontal rotation mechanism 13, ensuring stability in the stored state.

[0073] This solution decomposes the load-bearing function through a split platform structure. The second platform section 17 forms a fixed support point within the cabinet 1, preventing the movable door panel from bearing the main load. Through the above technical solution, this application resolves the positional interference problem between the sliding platform 12 and the riding platform 5 when the lower cabinet door 2 is closed, ensuring that the riding trainer 22 receives stable three-point support in the folded state. The split platform structure allows the first platform section 16 to complete only a small stroke movement during the closing process. Combined with the inward movement design of the hinge axis, this ensures that the lower...

[0074] The external force required to close the cabinet door 2 is reduced. The rigid support of the second platform section 17 within the cabinet body 1, combined with the locking function of the horizontal rotation mechanism 13, effectively prevents the equipment 22 from shaking or shifting when stored.

[0075] Furthermore, a gap is provided between the inner end of the extended guide rail 4 and the outer end of the curved guide rail 3, allowing the lower cabinet door 2 to open and close relative to the cabinet body 1. The gap refers to the physical distance between the end of the extended guide rail 4 near the cabinet body 1 and the end of the curved guide rail 3 away from the cabinet body 1. This gap can be achieved by staggering the ends of the rails or by setting a break structure. The width of this gap must ensure that the ends of the rails do not contact each other when the lower cabinet door 2 rotates. The extended guide rail 4 refers to the sliding path fixed to the inner wall of the lower cabinet door 2, which can be formed using metal profiles. Its extension direction matches the position of the lower cabinet door 2 after it is opened, guiding the riding platform 5 to slide outward from inside the cabinet body 1. The curved guide rail 3 refers to the curved slide rail fixed to the cabinet base plate 10, which can be manufactured using a stamping process. Its radius of curvature matches the spatial movement trajectory of the riding platform 5, controlling the position transition of the riding trainer 22 between the storage state and the use state. When the riding platform 5 is in the retracted state, its sliding path is entirely within the curved guide rail 3. At this time, the lower cabinet door 2 is in the closed state, and the gap between the extended guide rail 4 and the curved guide rail 3 provides clearance near the door's rotation axis. When the lower cabinet door 2 needs to be opened, the existence of the gap ensures that there is no rigid contact between the extended guide rail 4 and the curved guide rail 3 during the door's rotation around the hinge, allowing the door to freely flip to the fully opened position. When the riding platform 5 slides outward from the curved guide rail 3, it enters the extended guide rail 4 through the gap. The width of this gap is designed to be an integer multiple of the span of the riding platform 5's rollers 18, ensuring that the rollers 18 always maintain contact with at least one rail, thus maintaining sliding stability.

[0076] like Figure 2 and 5As shown, rollers 18 are installed on both sides of the lower end of the riding platform 5. Both the extended guide rail 4 and the arc-shaped guide rail 3 are parallel double-rail structures. At least one roller 18 on the riding platform 5 is positioned between the double rails to form an anti-detachment guide. The rollers 18 are rolling components installed on both sides of the bottom of the riding platform 5, and can be nylon wheels with bearings, used to support the weight of the riding platform 5 and reduce sliding friction resistance. The parallel double-rail structure is a track system composed of two spaced-apart metal profiles, providing a linear motion path for the rollers 18. The space between the double rails refers to the constraint space formed by the inner sides of the two track profiles, which can be achieved by adjusting the relationship between the distance between the double rails and the diameter of the rollers 18, restricting the horizontal displacement freedom of the rollers 18. When the riding platform 5 slides along the rails, the rollers 18 on both sides roll on their respective double-rail structures. At least one roller 18 is constrained within the inner space of the double-rail profiles, and the sidewall of the track and the rim of the roller 18 form mechanical interference. This structure allows the rim of the roller 18 to generate a contact reaction force with the sidewall of the track when the riding platform 5 is subjected to lateral force, thereby counteracting the tendency of lateral displacement. During the state switching process, whether the riding platform 5 is in the curved section of the arc guide track 3 or the straight section of the extended guide track 4, the dual-track structure always forms a three-dimensional spatial constraint on the roller 18, avoiding the risk of derailment caused by inertia or load offset.

[0077] like Figure 1-5 As shown, the top of the cabinet 1 is hinged with an upper cabinet door 19. A gas spring assembly 20 is provided between the upper cabinet door 19, the lower cabinet door 2, and the cabinet 1. When closed, the upper cabinet door 19 and the lower cabinet door 2 together seal the opening of the cabinet 1. The upper cabinet door 19, which is hinged at the top, refers to a door structure that can be flipped up by connecting the upper edge of the opening of the cabinet 1 via a rotating shaft. Specifically, it can be a hinged aluminum alloy door.

[0078] A stainless steel hinge is used, a design that positions the door's opening and closing axis at the top of cabinet 1, forming a double-door structure corresponding to the lower cabinet door 2. The pneumatic rod assembly 20 is an elastic support device connecting cabinet 1 and the cabinet door, specifically implemented using a double-headed nitrogen spring. This device provides thrust assistance when the cabinet door is opened and generates reverse damping when closed, forming a two-way elastic constraint. When operating the cabinet door, the upper cabinet door 19 rotates and unfolds around its top axis, and the lower cabinet door 2 rotates and unfolds around its bottom axis, forming a symmetrical opening and closing motion. The pneumatic rod assembly 20 provides lifting assistance when the upper cabinet door 19 unfolds, counteracting the resistance torque generated by the door's own weight; it simultaneously applies thrust when the lower cabinet door 2 unfolds, reducing operational intensity. In the closed state, the upper and lower cabinet doors are pressed together by the preload of the pneumatic rod assembly 20, forming a composite sealing interface, eliminating the structural defect of a single door panel bearing the weight of the equipment 22.

[0079] like Figure 1 and 2As shown, a detachable or flip-up tabletop 21 is located at the center of the interior of cabinet 1. When stowed, tabletop 21 can be detached or flipped to avoid obstructing the cycling trainer 22. The detachable tabletop 21 is a plate-like structure fixed to the center of cabinet 1 by connectors, specifically using clips or bolts. Users can manually remove the connectors to remove tabletop 21. This design eliminates rigid obstruction when storing the cycling trainer 22, preventing contact between tabletop 21 and the device 22. The flip-up tabletop 21 is a plate-like structure that changes its position via a rotating mechanism, specifically using hinges or pivots, allowing tabletop 21 to rotate around a fixed axis until it fits against the side wall of cabinet 1. This design, by adjusting the angle of tabletop 21, creates storage space for the cycling trainer 22 without requiring complete removal. Specifically, when the cycling trainer 22 is stowed, tabletop 21 changes its original position through detachment or flipping. In the disassembly method, the tabletop 21 is completely removed from the cabinet 1, eliminating the obstruction of the middle height; in the flipping method, the tabletop 21 rotates around the hinge point until it is parallel to the inner wall of the cabinet 1, reducing its own space occupation. Both methods change the spatial relative relationship between the tabletop 21 and the cycling trainer 22, avoiding their vertical overlap and thus eliminating vibration transmission paths caused by structural interference. When the cycling trainer 22 is stored, it only contacts the rigid support point of the cabinet 1, and vibration energy cannot be transmitted to other parts of the cabinet 1 through the tabletop 21, reducing the risk of stress concentration. Compared with existing technologies, traditional cabinet-type fitness equipment does not consider the spatial interference problem of internal functional components. Fixed shelves are prone to rigid contact when the equipment is stored, causing vibration energy to be directly transmitted to the weak parts of the cabinet. This solution, through the adjustable tabletop 21 structure, provides an interference-free storage space for the cycling trainer 22 while maintaining the multifunctionality of the cabinet 1, avoiding reliability degradation caused by structural conflicts.

[0080] Furthermore, cabinet 1 integrates a multimedia function module, including a power supply interface and a display device mounting structure. The multimedia function module refers to the integrated functional unit located within cabinet 1, which can be implemented using a combination of pre-installed circuit boards and standard interfaces, used for centralized management of the power supply and signal transmission needs of electronic devices. The power supply interface refers to the power contact point for connecting external electronic devices, which can be implemented using an embedded socket or USB charging port, directly connected to the mains power or battery system via the cabinet 1's built-in power distribution lines. The display device mounting structure refers to the support device for fixing the display screen, which can be implemented using a sliding rail bracket or a quick-release clip structure, achieving quick positioning and stable support of the display screen through preset mounting positions. When the multimedia function module is installed inside cabinet 1, the power supply interface connects to an external power source through the built-in power distribution system, providing a stable power supply for cycling training-related electronic devices, such as heart rate monitors or smart terminals.

[0081] The device's mounting structure features a standardized interface design, allowing users to select the appropriate display screen type based on their training needs. The display screen is secured by sliding it into a pre-set slot via a slide rail, and can be released by pressing the release button. During cycling training, the electronic device continuously draws power from the power interface, and the display screen maintains the optimal viewing angle thanks to the mounting structure. The multimedia function module integrates all components to work collaboratively, ensuring that human-computer interaction needs are met during training.

[0082] Compared to existing technologies, the patent solution with publication number CN2230175Y only provides equipment storage functionality, lacking any electronic device support structure within the cabinet. Users need to manually route power cables when using an external display, posing a risk of cable tangling, and the unstable placement of the display can lead to viewing angle shifts. This solution eliminates the need for external wiring by integrating a power supply interface, and utilizes a display device mounting structure to ensure display positioning accuracy, achieving plug-and-play functionality for electronic devices while maintaining efficient use of cabinet 1 space. Through the above technical solutions, this application provides continuous power for cycling training, avoiding safety hazards caused by external power cables. The display mounting structure ensures the stability of the equipment during training, and the integrated design of the multimedia function modules enables cabinet 1 to simultaneously possess both equipment storage and training support functions, solving the problem of traditional cycling cabinets lacking electronic device compatibility.
