Description

Technical Field

[0001] This invention relates to the field of rehabilitation and fitness equipment technology, specifically to a hip exercise device and method suitable for prenatal and postpartum rehabilitation of pregnant women, postoperative rehabilitation of hip joints, and training of pelvic floor muscles and hip muscles. Background Technology

[0002] Hip opening and closing exercises are an important training method for pregnant and postpartum women in terms of prenatal pelvic preparation, postpartum pelvic floor muscle and hip joint function recovery, post-hip surgery rehabilitation, and daily lower limb shaping. Existing hip exercise equipment generally suffers from the following technical shortcomings: The seats, pedals, and armrests are mostly independent, separate structures, resulting in poor overall stability, large space occupation, and inconvenience in disassembly, assembly, and relocation, making them unsuitable for home and small rehabilitation room settings. Bilateral movements lack forced synchronous constraint, easily leading to inconsistent opening and closing ranges, causing asymmetrical stress on the hip joints and potentially causing muscle strains and joint wear. The damping mechanism only provides resistance and lacks hip support. The seat only provides support and does not participate in movement damping or synchronous control, resulting in limited functionality and redundant structure. Adjusting the exercise range and damping intensity is inconvenient, making it impossible to accurately adapt to individuals of different heights, weights, and exercise stages, easily leading to overstretching or insufficient exercise effectiveness. Summary of the Invention

[0003] In view of this, the main objective of this invention is to propose a hip exercise device and method that integrates the seat, pedal, and drive armrest into a single design. The scissor-type structure ensures forced synchronization on both sides, and the damping mechanism combines motion resistance with hip support. Exercisers can coordinate their hand and foot movements, significantly reducing the barrier to entry for exercise and improving safety, comfort, and exercise efficiency.

[0004] To achieve the above objectives, the first objective of the present invention is to provide a hip exercise device, including a dual slide rail assembly, a seat assembly, two sets of drive exercise units, and a damping linkage mechanism. The dual slide rail assembly includes two slide rails arranged in parallel, each slide rail including a guide beam and a sliding seat slidably connected to the guide beam; The seat assembly is mounted transversely across the middle of the two slide rails; the seat assembly includes two pedal structures and a seat body connected between the two pedal structures, the pedal structures are mounted transversely across the two slide rails, and the seat body is fixedly mounted on the top surface of the middle of the two pedal structures; The two sets of drive exercise units are symmetrically arranged on both sides of the seat body to drive the interior of the seat body to perform opening and closing movements; The damping linkage mechanism is connected to the upper surface of the seat body and is used to provide motion damping for the opposing / backward sliding movements inside the seat body, support the human buttocks, and constrain the opening and closing movements inside the seat body.

[0005] In some embodiments, the seat body includes a first support link and a second support link, one end of the first support link is hinged to one of the sliding seats, one end of the second link is hinged to the other sliding seat, and the other end of the first support link and the other end of the second support link are hinged to each other to form a scissor-type synchronous structure.

[0006] In some embodiments, the first support rod includes a vertical support rod and a horizontal support rod and an inclined connecting rod connected to both ends of the vertical support rod. The top of the vertical support rod is vertically fixed to the middle of the horizontal support rod, the top of the inclined connecting rod is vertically fixed to the middle of the horizontal support rod, and the other end is inclined outward and fixed to the side wall of the sliding seat on the corresponding side. The bottom end of the vertical support rod is fixedly connected to the driving exercise unit on the corresponding side.

[0007] In some embodiments, each set of drive exercise units includes a telescopic part extending obliquely upwards towards the side of the corresponding side sliding seat, a grip part for the exerciser to hold, and a connecting part. One end of the connecting part is horizontally fixedly connected to the bottom end of the vertical support rod, and the other end of the connecting part is fixedly connected to the bottom end of the telescopic part. The top end of the telescopic part is fixedly connected to one end of the grip part, and the grip part is located on the outside of the seat body, and the axis of the grip part is perpendicular to the axis of the guide beam.

[0008] In some embodiments, the damping linkage mechanism includes a damping assembly, which includes at least one elastic damping element. The two ends of the elastic damping element are respectively connected to the two support linkage assemblies to provide elastic damping for the opposite sliding of the two sliding seats.

[0009] In some embodiments, the elastic damping element is a plurality of elastic support rubber bands, with each end of the elastic support rubber band being respectively sleeved on two horizontal support rods, and the horizontal tension of the elastic support rubber bands being adjusted by the horizontal displacement of the two horizontal support rods.

[0010] In some embodiments, rail beam seats are fixed at both ends of the two guide rail beams, and the rail beam seats are used to limit the sliding limit position of the sliding seat. The guide rail beam is also provided with a stroke adjustment mechanism, which includes multiple sets of limiting holes arranged along the axial direction of the guide rail beam, limiting pins adapted to the limiting holes, and limiting plates. The limiting pins are inserted into the corresponding limiting holes and connected to the limiting plates to limit the maximum sliding stroke of the sliding seat.

[0011] In some embodiments, the telescopic part is a telescopic rod structure that can be extended and adjusted, and the telescopic rod structure is provided with a locking member for locking the extension length; the outer periphery of the grip part is covered with an anti-slip grip sleeve.

[0012] In some embodiments, the pedal structure includes a pedal body, the upper surface of which is provided with an anti-slip textured structure, and the edge of the pedal body is provided with an upwardly protruding foot limiting stop.

[0013] A second objective of this invention is to provide a hip exercise method, implemented based on the hip exercise device described above, comprising the following steps: S1: The exerciser sits on the seat assembly, places both feet on the pedal structure on both sides, holds the grips of the drive exercise unit on both sides with both hands, and adjusts the body to a comfortable exercise posture. S2: The exerciser applies force simultaneously with their legs and upper limbs, and drives the sliding seat of the double slide rail assembly to slide in opposite directions along the guide rail beam through the drive exercise unit, completing the opening and closing exercise movements of hip joint adduction and abduction; S3: During the opening and closing exercise movements, the damping linkage mechanism provides synchronous damping for the movement of the seat assembly, constrains the bilateral movements to be carried out synchronously, and achieves muscle resistance training through damping force.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: The hip exercise device described in this application includes a dual-slide rail assembly, a seat assembly, two sets of drive exercise units, and a damping linkage mechanism. The seat body, pedal structure, and dual-slide rail assembly are integrated into one unit, resulting in a lower center of gravity, greater rigidity, and a smaller footprint. No additional installation or fixation is required, making it more convenient to use and move. The damping linkage mechanism is directly located on the upper surface of the seat body, simultaneously providing hip support, motion damping, and synchronous constraint. This significantly simplifies the structure, reduces the number of parts, lowers costs and failure rates, and significantly improves comfort and structural stability. The damping linkage mechanism directly constrains the opposing / reverse movements within the seat body, ensuring that the sliding seats and pedals on both sides always move synchronously and symmetrically from a transmission structure perspective. This avoids left-right movement deviations, eliminates lateral shear forces on the hip joint, and reduces the risk of muscle strain and joint injury. The drive exercise units are symmetrically arranged on both sides of the seat body and directly drive the internal opening and closing. Exercisers can complete the opening and closing movements by simultaneously applying force with their legs and upper limbs, distributing the force burden and lowering the physical fitness threshold for exercise. This makes it more suitable for pregnant women, postpartum women, and those in rehabilitation who have weaker physical strength. Attached Figure Description

Detailed Implementation

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. In the description of this invention, it should be noted that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. refer to Figures 1 to 5 As shown, one embodiment of the present invention provides a hip exercise device, which includes a double slide rail assembly 1, a seat assembly 2, two sets of drive exercise units 3, and a damping linkage mechanism 4, wherein: The dual slide rail assembly 1 includes two slide rails arranged in parallel. Each slide rail includes a guide beam and a sliding seat, with the sliding seat slidably connected to the guide beam. The seat assembly 2 is mounted across the middle of the two slide rails. The seat assembly includes two pedal structures 21 and a seat body 22, wherein the seat body 22 is connected between the two pedal structures 21. Each pedal structure 21 is mounted across the middle of the two slide rails, and the seat body 22 is fixedly mounted on the top surface of the middle of the two pedal structures 21. Two sets of drive exercise units 3 are symmetrically arranged on both sides of the seat body 22 to drive the opening and closing movement inside the seat body 22; The damping linkage mechanism 4 is connected to the upper surface of the seat body 22. It is used to provide motion damping for the sliding motion of the seat body 22 in opposite directions and to support the human buttocks, and to constrain the opening and closing motion of the seat body 22.

[0018] Specifically, in this embodiment, the dual slide rail assembly 1 includes a slide rail base 11, a rail beam seat 12, and a limiting plate 13. The slide rail base 11 consists of two sets of parallel slide rails (i.e., the first slide rail 111 and the second slide rail 112), each set of slide rails consisting of a guide rail beam and a sliding seat. Preferably, the guide rail beam is composed of a first guide rail beam 1111 and a second guide rail beam 1121. The guide rail beam can be made of cylindrical or square cross-section hard aluminum alloy with a smooth, wear-resistant, and rust-proof surface. The sliding seat is composed of a first sliding seat 1112 and a second sliding seat 1122. The bottom of the sliding seat is inlaid with a linear bearing or a wear-resistant plastic sleeve, allowing it to slide smoothly left and right along the guide rail beam without jamming or deviation.

[0019] In this embodiment, the hip exercise device first establishes a stable linear sliding pair between the double slide rail assembly 1 and the sliding seat via parallel guide beams. This provides a rigid motion guide foundation for the entire device, ensuring stable operation of the hip opening and closing movements along the horizontal axis. Under this premise, the integrated seat assembly 2 rigidly integrates the pedal structure 21 and the seat body 22, spanning across the middle of the double slide rails. This allows the foot support structure and the hip support structure to form a synchronous motion carrier, structurally eliminating the displacement deviation and force imbalance problems that are prone to occur in split-type devices. The two symmetrically arranged drive exercise units 3 directly coordinate with the seat body 22, enabling the exerciser to drive the seat body 22 to complete opposite / reverse opening and closing movements through coordinated leg extension and upper limb traction. This transforms the traditional single leg-powered mode into a combined hand and foot-powered mode, significantly improving the hip opening and closing performance. The reduced force load on individual muscle groups makes it more suitable for the exercise needs of users with weaker physical strength, such as pregnant women, postpartum women, and those undergoing rehabilitation. The damping linkage mechanism 4, which is connected to the upper surface of the seat body 22, simultaneously achieves three core functions in the same structural position: first, it provides continuous and controllable damping resistance for opening and closing movements to achieve resistance training effects; second, it directly supports the buttocks to form integrated support to improve user comfort; and third, it forcibly constrains the two sides of the seat body 22 to maintain synchronous movement from the transmission end, fundamentally avoiding the risk of hip joint shear force and muscle strain caused by asymmetric left and right movements. The overall technical process achieves a high degree of integration of five major functions: sliding guidance, integrated load bearing, coordinated drive, damping support, and synchronous constraint. Ultimately, the equipment has a comprehensive technical effect of compact and stable structure, precise and standardized movement trajectory, easy and effortless force exertion, safe and comfortable use, and wide applicability to a wide range of users.

[0020] In some embodiments, the seat body 22 includes a first support link 221 and a second support link 222. One end of the first support link 221 is hinged to one of the sliding seats, one end of the second support link 222 is hinged to the other sliding seat, and the other end of the first support link 221 and the other end of the second support link 222 are hinged to each other to form a scissor-type synchronous structure.

[0021] Specifically, in this embodiment, the seat body 22 adopts a scissor-type synchronous structure formed by the hinge of the first support link 221 and the second support link 222. The outer ends of the two links are fixedly connected to the corresponding side sliding seats. When one side sliding seat is displaced by the driving exercise unit 3, it will drive the scissor-type link to open or close synchronously through the hinge point, thereby forcibly driving the other side sliding seat to make equal and opposite symmetrical movements. This purely mechanical linkage technology process can achieve absolute synchronization of bilateral movements without the need for electronic control or additional auxiliary structures, effectively avoiding the problems of uneven opening and closing amplitude and hip joint force deviation. At the same time, the scissor-type hinge structure has smooth movement, sufficient rigidity, and small space occupation. It can provide stable support for the seat body 22 and ensure that the linear movement trajectory does not deviate, significantly improving the movement stability, use safety, and exercise movement standardization of the equipment.

[0022] In some embodiments, the first support rod 221 includes a vertical support rod 2211, a horizontal support rod 2212, and an inclined connecting rod 2213. The horizontal support rod 2212 and the inclined connecting rod 2213 are connected to the two ends of the vertical support rod 2211. The top of the vertical support rod 2211 is vertically fixed to the middle of the horizontal support rod 2212. The top of the inclined connecting rod 2213 is vertically fixed to the middle of the horizontal support rod 2212, and the other end is inclined outward and fixed to the side wall of the corresponding side sliding seat. The bottom end of the vertical support rod 2211 is fixedly connected to the driving exercise unit 3 on the corresponding side.

[0023] Specifically, the first support link 221 adopts an integral rigid connection structure of vertical support rod 2211, horizontal support rod 2212 and inclined connecting rod 2213. The horizontal support rod 2212 and inclined connecting rod 2213 are vertically fixed to the top of the vertical support rod 2211 to form a stable support node. The inclined connecting rod 2213 is inclined outward to connect to the sliding seat to transmit linear motion and convert it into scissor-type opening and closing action. The bottom of the vertical support rod 2211 is directly connected to the drive exercise unit 3 to achieve uniform transmission of drive load. This integrated rigid support structure can efficiently integrate and transmit the linear displacement of the sliding seat, the force applied by the drive exercise unit 3 and the support force of the damping linkage mechanism 4, effectively improving the overall structural strength and motion rigidity of the seat body, avoiding deformation, shaking or abnormal noise under force, and accurately maintaining the relative position and transmission angle between the sliding seat, the drive exercise unit 3 and the seat body 22, ensuring smooth and lossless motion transmission, further enhancing the accuracy of bilateral synchronous motion, the stability of exercise force, and the reliability of long-term use of the equipment.

[0024] In some embodiments, each set of drive exercise units 3 includes a telescopic part 31 that extends obliquely from bottom to top toward the side of the corresponding side sliding seat, a grip part 32 for the exerciser to hold, and a connecting part 33. One end of the connecting part 33 is horizontally fixedly connected to the bottom end of the vertical support rod 2211, and the other end of the connecting part 33 is fixedly connected to the bottom end of the telescopic part 31. The top end of the telescopic part 31 is fixedly connected to one end of the grip part 32, and the grip part 32 is located on the outside of the seat body 22. The axis of the grip part 32 is perpendicular to the axis of the guide beam.

[0025] In some embodiments, the damping linkage mechanism 4 includes a damping assembly, which includes at least one elastic damping element. The two ends of the elastic damping element are respectively connected to two horizontal support rods 2212 to provide elastic damping for the opposite sliding of the two sliding seats.

[0026] In this embodiment, the damping linkage mechanism 4 directly connects the two ends of the elastic damping element to two horizontal support rods 2212. When the sliding seat drives the support rod to slide in opposite directions, the distance between the horizontal support rods 2212 increases and stretches the elastic damping element to generate reverse elastic resistance, providing a stable and controllable resistance training effect for the hip abduction movement. When the exerciser exerts force, the elastic damping element retracts and resets, causing the sliding seat and support rod to automatically and synchronously close to complete the adduction movement. This elastic damping transmission process is direct, smooth, and without mechanical impact, which can ensure a uniform and stable training load and achieve automatic reset of the movement. At the same time, the structure is simple and reliable, and the installation and maintenance are convenient, significantly improving the continuity, comfort, and stability of the exercise and the use of the equipment.

[0027] In some embodiments, the elastic damping element is a plurality of elastic support rubber bands 41, with the two ends of the elastic support rubber bands 41 respectively sleeved on two horizontal support rods, and the horizontal tension of the elastic support rubber bands 41 is adjusted by the horizontal displacement of the two horizontal support rods 2212.

[0028] In this embodiment, multiple elastic support rubber bands 41 are used as elastic damping components. Their two ends are directly sleeved on two horizontal support rods 2212. When the sliding seat causes the horizontal support rods 2212 to move horizontally in opposite directions, the elastic support rubber bands 41 are stretched synchronously and generate uniform elastic damping force, providing stable resistance for hip abduction movement. The tension and damping strength of the rubber bands can be adjusted in real time by the displacement of the horizontal support rods 2212. When the exerciser exerts force, the rubber bands elastically retract and drive the structures on both sides to automatically reset. This sleeve-type installation method is simple and reliable, the damping adjustment is intuitive and convenient, and the force is uniform and without jamming. It can meet the exercise intensity needs of different groups of people, and ensure the synchronicity of bilateral movement and the smoothness of reset, thereby improving the adaptability, comfort of use and convenience of maintenance of the equipment.

[0029] In some embodiments, rail beam seats 12 are fixed at both ends of the two guide beams, and the rail beam seats 12 are used to limit the sliding limit position of the sliding seat.

[0030] Specifically, the first guide rail beam 1111 and the second guide rail beam 1121 are parallel to each other and maintain a fixed distance. Both ends are equipped with rail beam seats 12, which are fixed with bolts or clips to prevent the sliding seat from sliding out of the guide rail beam, thus forming mechanical limit protection.

[0031] In some embodiments, the guide beam is also provided with a stroke adjustment mechanism. The stroke adjustment mechanism includes multiple sets of limiting holes arranged along the axial direction of the guide beam, limiting pins adapted to the limiting holes, and limiting plates 13. The limiting pins are inserted into the corresponding limiting holes and connected to the limiting plates 13 to limit the maximum sliding stroke of the sliding seat.

[0032] In this embodiment, the rail beam seats 12 at both ends of the guide beam can provide extreme position protection for the sliding seat, preventing the sliding seat from falling off the guide rail and causing safety hazards. At the same time, in conjunction with the stroke adjustment mechanism composed of limiting holes, limiting pins and limiting plates 13 distributed along the axial direction of the guide beam, the limiting pins can be inserted into the limiting holes at different positions to change the fixed position of the limiting plate 13, thereby precisely limiting the maximum outward sliding stroke of the sliding seat and controlling the opening and closing range of the hip. This combination of mechanical limiting and stroke adjustment technology can flexibly set the safe range of motion according to the height, physical strength and rehabilitation stage of the exerciser, effectively preventing joint or muscle damage caused by overstretching, improving the safety of equipment use and the adaptability to the user, and is simple in structure, easy to adjust and stable and reliable in operation.

[0033] In some embodiments, the telescopic part 31 is a telescopic rod structure that can be extended and adjusted, and the telescopic rod structure is provided with a locking member for locking the extension length; the grip part 32 is covered with an anti-slip grip sleeve 321.

[0034] In this embodiment, the telescopic part 31 of the driving exercise unit 3 adopts an adjustable telescopic rod structure and is equipped with a locking component. It can freely adjust the telescopic length according to the height and arm length of the exerciser and reliably lock it, so that the grip part is always at a comfortable and ergonomic height. At the same time, the anti-slip grip sleeve 321 on the outer periphery of the grip part 32 can increase the friction of hand contact, absorb sweat and cushion, and prevent slippage during exercise. This technical solution can achieve high adaptability to different groups of people, significantly improve grip stability and comfort, and ensure that the process of hand and foot coordination is smooth, safe and controllable.

[0035] In some embodiments, the pedal structure 21 includes a pedal body 211, the upper surface of the pedal body 211 is provided with an anti-slip texture structure 212, and the edge of the pedal body 211 is provided with an upwardly protruding foot limiting stop 213.

[0036] Therefore, by setting an anti-slip texture structure 212 on the pedal body 211, the pedal structure 21 can increase the friction between the exerciser's foot and the pedal, preventing slippage and deviation when exerting force. At the same time, the foot limiting edge 213 with its upward protruding edge forms a lateral enclosure and limiting of the foot, effectively restraining the position of the foot during exercise, preventing slippage or misalignment during pedaling, thereby ensuring stable force exertion, standardized movements, improving the safety and accuracy of the exercise process, and making the force on the hip exercise more even and controllable.

[0037] Please see Figure 6 As shown, another embodiment of the present invention also provides a hip exercise method, implemented based on the hip exercise device described above, the hip exercise method comprising the following steps: S1: The exerciser sits on the seat assembly, places both feet on the foot pedals on both sides, holds the handles on both armrests with both hands, and adjusts the body to a comfortable exercise posture. S2: The exerciser applies force simultaneously with their legs and upper limbs, and drives the sliding seat of the double slide rail assembly to slide in opposite directions along the guide rail beam through the drive exercise unit, completing the opening and closing exercise movements of hip joint adduction and abduction; S3: During the opening and closing exercise movements, the damping linkage mechanism 4 provides synchronous damping for the movement of the seat assembly 2, constraining the bilateral movements to be carried out synchronously, and realizing muscle resistance training through damping force.

[0038] In some embodiments, before step S1, there is a pre-adjustment step for exercise parameters: according to the exerciser's physical strength and exercise needs, the damping force of the damping component is adjusted by the damping adjustment knob, and the maximum sliding stroke of the sliding seat is adjusted by the stroke adjustment mechanism.

[0039] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of this invention.
