Description

Technical Field

[0001] This application relates to the field of rehabilitation equipment technology, and more specifically, to an upper and lower limb training device. Background Technology

[0002] In recent years, with the increasing number of patients recovering from stroke, brain injury, spinal cord injury, cerebral palsy, Parkinson's syndrome, multiple sclerosis, and various sports injuries, limb dysfunction has become one of the major obstacles affecting patients' daily lives and social participation. For these individuals, hospital physical therapy and home rehabilitation commonly utilize various upper and lower limb training devices. These devices, through passive or active assistance, promote joint movement, maintaining and improving joint range of motion, promoting blood circulation in the affected limb, preventing soft tissue adhesions and muscle atrophy, reducing abnormal muscle tone and spasticity, and promoting neuromuscular remodeling and motor function recovery.

[0003] Upper and lower limb training equipment typically includes upper limb training equipment and lower limb training equipment. In existing technologies, upper limb training equipment is mostly fixed to lower limb training equipment. Although this fixed structure can ensure overall stability, due to significant individual differences in users' height, arm length, and rehabilitation level, it is often difficult to accurately adjust the handles or grips to match the patient's upper limb physiological axis and grip position during training. This leads to discomfort such as arm restriction, unnatural posture, and force line misalignment during training, thus affecting the training effect. Utility Model Content

[0004] The purpose of this application is to provide an upper and lower limb training device to address the shortcomings of the aforementioned technology.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] This application provides an upper and lower limb training device, including an upper limb training device and a lower limb training device. The upper limb training device includes a housing and a rotating training mechanism. The rotating training mechanism includes a drive component installed in the housing and two first handles respectively connected to the output shafts at both ends of the drive component. The two first handles are arranged symmetrically about the center point of the drive component. The housing is slidably installed on the lower limb training device in the horizontal direction to drive the upper limb training device to slide horizontally relative to the lower limb training device.

[0007] Furthermore, the upper limb training device also includes a sliding mechanism, which includes a guide rail extending in a horizontal direction and a slider slidably connected to the guide rail. The guide rail is connected to the housing, and the slider is connected to the lower limb training device.

[0008] Furthermore, the upper limb training device also includes an electrical stimulation mechanism, which includes a circuit board installed inside the housing and electrode pads electrically connected to the circuit board. The electrode pads are used to adhere to the skin surface of the upper limb for electrical stimulation.

[0009] Furthermore, the housing includes a first housing and a second housing arranged in a horizontal direction, a rotating training mechanism is installed in the first housing, and the second housing is slidably connected to the lower limb training device. The first housing can rotate relative to the second housing in a vertical plane and drive the two first handles to switch between a first position and a second position.

[0010] In the first position, the two first handles are located on both sides of the drive assembly along the horizontal direction. In the second position, the two first handles are located on both sides of the drive assembly along the vertical direction.

[0011] Furthermore, the upper limb training device also includes a first angle adjustment mechanism, which includes a first locking member and a first adapter plate and a first turntable assembly arranged coaxially in the horizontal direction. The first adapter plate is connected to the first housing, and the first turntable assembly is connected to the second housing.

[0012] The first locking member passes through the first turntable assembly and abuts or dismounts from the first adapter plate. When the first locking member dismounts from the first adapter plate, the first adapter plate rotates in the vertical plane relative to the first turntable assembly, and drives the first housing to rotate relative to the second housing.

[0013] Furthermore, a first limiting member is provided on the first adapter plate, and a first arc-shaped groove that cooperates with the first limiting member is provided on the first turntable assembly. When the first adapter plate rotates relative to the first turntable assembly, the first limiting member slides in the first arc-shaped groove to limit the rotation angle of the first housing relative to the second housing.

[0014] Furthermore, a second handle is symmetrically arranged on both sides of the shell along the horizontal direction. The upper limb training device also includes a second angle adjustment mechanism. The first angle adjustment mechanism includes a second locking member and a second adapter plate and a second turntable assembly arranged coaxially along the vertical direction. The second adapter plate is connected to the shell, and the second turntable assembly is connected to the lower limb training device.

[0015] The second locking member passes through the second turntable assembly and abuts or dismounts from the second adapter plate. When the second locking member dismounts from the second adapter plate, the second adapter plate rotates in the horizontal plane relative to the second turntable assembly, and drives the upper limb training device to rotate relative to the lower limb training device through the housing, so as to adjust the distance between the first handle, the second handle and the user.

[0016] Furthermore, a second limiting member is provided on the second adapter plate, and a second arc-shaped groove that cooperates with the second limiting member is provided on the second turntable assembly. When the second adapter plate rotates relative to the second turntable assembly, the second limiting member slides in the second arc-shaped groove to limit the rotation angle of the upper limb training device relative to the lower limb training device.

[0017] Furthermore, the upper limb training device also includes a display mechanism, which includes a base, a support frame, and a display screen. The base is rotatably mounted on the surface of the housing, one end of the support frame is hinged to the base, and the other end is connected to the display screen via a ball joint.

[0018] Furthermore, the rotation training mechanism also includes a sensor installed inside the housing and a positioning pin disposed on the output shaft of the drive component. The positioning pin periodically contacts the sensor as the output shaft of the drive component rotates, so that the sensor can measure the rotation angle and position of the output shaft of the drive component.

[0019] The beneficial effects of this application include:

[0020] This application provides an upper and lower limb training device, including an upper limb training device and a lower limb training device. The upper limb training device includes a housing and a rotating training mechanism. The rotating training mechanism includes a drive component installed within the housing and two first handles respectively connected to output shafts at both ends of the drive component. The two first handles are centrally symmetrically arranged. The housing is slidably mounted on the lower limb training device in a horizontal direction, allowing the two first handles to adapt to different upper limb lengths. Through the sliding adjustment design, the horizontal position of the upper limb training device relative to the lower limb training device can be adjusted according to the height and upper limb length of different users, thereby changing the horizontal distance between the first handles and the human body. This ensures that each user can train in a suitable position, avoiding discomfort during training and greatly improving the applicability and rehabilitation effect of the device. In summary, the upper and lower limb training device provided by this application has the advantages of simple structure, strong adaptability, and convenient operation, and can meet the rehabilitation needs of different users, possessing broad market application prospects.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. It should be noted that, unless otherwise specified, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0037] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application 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, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0039] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" 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 application based on the specific circumstances.

[0040] The technical solution of this application will be described in detail below with reference to specific embodiments.

[0041] This application provides an upper and lower limb training device, designed to offer more efficient and personalized rehabilitation training for various groups undergoing neurological rehabilitation or postoperative recovery. For example... Figures 1 to 4 As shown, the device includes an upper limb training device and a lower limb training device, and through clever design, achieves synergistic action between the upper and lower limbs, helping users achieve more precise rehabilitation training. The upper limb training device includes a housing 1 and a rotating training mechanism 2. The rotating training mechanism 2 includes a drive assembly 21 installed inside the housing 1, and two first handles 26 respectively connected to the output shafts at both ends of the drive assembly 21. This structural design allows users to obtain stable support and a comfortable training experience during training. The lower limb training device is the same as or can be implemented using existing technology, and will not be described in detail here.

[0042] Specifically, the two first handles 26 are centrally symmetrical about the center point of the drive component 21, allowing the upper limbs to better simulate the natural movement patterns of the human body during training, achieving coordinated up-and-down or forward-and-backward movements, thereby improving training effectiveness. This design conforms to the physiological characteristics of humans when performing limb movements, helping to enhance the smoothness and naturalness of movement and reduce potential discomfort during training. It should be understood that the drive component 21 is typically rectangular or cylindrical. When the drive component 21 is rectangular, its center point is the intersection of the midlines along the length, width, and height directions; when the drive component 21 is cylindrical, its center point is the midpoint of the line connecting the centers of the two circular bases.

[0043] To accommodate users with varying upper limb lengths, the housing 1 is horizontally slidable onto the lower limb training device. This sliding design allows the horizontal position of the upper limb training device relative to the lower limb training device to be adjusted according to the user's specific needs, thereby changing the horizontal distance between the first handle 26 and the body. This ensures that the first handle 26 matches the user's arm length and natural position without requiring the user to adjust their own position, greatly improving convenience and comfort during training. Whether standing or sitting, users can easily adjust the horizontal position of the upper limb training device during rehabilitation training, ensuring that both the upper and lower limbs are at appropriate angles and positions, thus avoiding unnecessary postural discomfort and ensuring a smooth and efficient training process. Furthermore, the adjusted position helps users grip the first handle 26 more naturally, enhancing stability during training, improving upper limb coordination, and promoting rehabilitation effects.

[0044] To further enhance the adaptability of the device, the drive assembly 21 can employ a motor with dual output shafts. The motor design not only provides the necessary power for training but also allows for the selection of different training modes based on the needs of different individuals. Specifically, users can choose between active or passive training modes according to their rehabilitation needs. During the postoperative recovery period, users can choose passive training mode, where the motor rotates at an appropriate speed, driving the upper limbs gripping the first handle 26 to move, thereby helping patients regain upper limb mobility. In active training mode, users can use their own strength to rotate the first handle 26, while the motor rotates in the opposite direction, increasing resistance and assisting users in strength training, enhancing muscle strength and coordination, and achieving good exercise results. This design not only meets the needs of postoperative rehabilitation patients but can also be widely applied to home exercise, helping users improve their sub-health status.

[0045] Overall, through its sliding adjustment design, the upper limb training device can be personalized according to the height and upper limb length of different users, ensuring that each user can train in a suitable position, avoiding discomfort during training, and greatly improving the device's applicability and rehabilitation effect. Furthermore, by combining upper and lower limb coordinated training, the device can effectively promote the coordination of muscles throughout the body, contributing to the user's overall rehabilitation process. In conclusion, the upper and lower limb training device provided in this application has advantages such as simple structure, strong adaptability, and convenient operation, and can meet the rehabilitation needs of different users, possessing broad market application prospects.

[0046] Furthermore, such as Figure 6 As shown, the upper limb training device also includes an electrical stimulation mechanism 4, which provides additional rehabilitation methods and enhances the training effect. The electrical stimulation mechanism 4 includes a circuit board 41, mounting studs 42, terminals 43, and electrode pads. These components work together to achieve electrical stimulation of the user's upper limbs.

[0047] The circuit board 41 is securely fixed inside the housing 1 by mounting studs 42, ensuring that the circuit board 41 maintains a stable position during use. One end of the wiring terminal 43 connects to the circuit board 41, and the other end extends out from the side of the housing 1, facilitating connection to the cables of external electrode pads, thereby achieving electrical connection between the circuit board 41 and the electrode pads. When electrical stimulation training is required, the electrode pads are adhered to the patient's upper limb skin surface using an appropriate fixing method and electrically connected to the circuit board 41. The circuit board 41 transmits electrical stimulation signals, controlling the electrode pads to generate intermittent current pulse signals, which directly act on the upper limb skin surface, thereby achieving neuromuscular electrical stimulation.

[0048] This electrical stimulation sends intermittent signals to nerves and muscles through the skin surface, effectively activating neuromuscular function, promoting muscle contraction and relaxation, and thus aiding in the reversal of neural function. Reversal remodeling refers to reactivating damaged or inhibited nervous systems through electrical stimulation, promoting their recovery and functional regeneration. This technology plays a crucial role in neurological rehabilitation and postoperative recovery, particularly for patients with upper limb dysfunction due to stroke, spinal cord injury, or other neurological disorders, effectively promoting neuromuscular recovery.

[0049] Furthermore, the output mode of the electrical stimulation signal can be adjusted according to the different rehabilitation needs of patients. The device offers a variety of modes, including different frequencies, intensities, and time intervals, to adapt to the specific rehabilitation progress and training needs of patients. For example, patients in the early stages of rehabilitation can choose low-frequency and low-intensity electrical stimulation to gradually activate damaged nerves; while patients with better recovery progress can choose high-frequency and high-intensity electrical stimulation signals to promote deeper nerve and muscle function recovery.

[0050] Furthermore, such as Figure 3 As shown, housing 1 includes a first housing 14 and a second housing 15 arranged horizontally. The first housing 14 has an L-shaped side structure, with an uneven top surface. The higher side of this L-shaped structure is specifically designed for mounting the rotation training mechanism. The motor of the rotation training mechanism is securely fixed inside the first housing 14 by mounting blocks 22 and screws passing through the blocks 22. This motor mounting design not only ensures the stability of the motor during training but also effectively reduces vibration and noise, improving the user comfort and durability of the device. Two first handles 26 are mounted on the motor output end, extending from both sides of the first housing 14, allowing the user to perform upper limb training. A first cover plate 11 is provided on the opening of the higher top surface of the L-shaped structure to protect the motor and its internal components, ensuring the stability and durability of the motor during operation. Furthermore, the lower side of the L-shaped structure is adjacent to the second housing 15, and a second cover plate 12 is provided on its top opening to protect the internal components.

[0051] The circuit board 41 of the electrical stimulation mechanism 4 is installed inside the second housing 15. To protect the circuit board 41, a third cover plate 13 is provided on the top opening of the second housing 15, effectively preventing external factors from damaging the circuit board 41. Through this multi-layered protection design, the device enhances safety and durability while ensuring functionality. The bottom of the second housing 15 is connected to the lower limb training device via a sliding connection, allowing users to adjust the position of the upper limb training device as needed, ensuring that the device can provide a suitable movement position for different user body types and training needs.

[0052] Furthermore, to further enhance the stability of the device and improve user safety during use, second handles 16 are symmetrically mounted on both sides of the second housing 15 using screws. The design of the second handles 16 allows users to maintain stability and balance by holding them with both hands when not performing upper limb dynamic training (such as lower limb training). Especially when sitting or standing, the second handles 16 effectively provide support, enhancing user safety and preventing accidents caused by unstable postures. This design not only improves the functionality of the device but also increases its adaptability, meeting the needs of different users.

[0053] It should be noted that each part of the housing 1, including the first cover plate 11, the second cover plate 12, the third cover plate 13, the first housing 14, and the second housing 15, is provided with multiple holes for installation and connection. The design of these holes provides a more convenient assembly method, ensuring that the various components can be securely connected, while also facilitating disassembly and assembly during production, maintenance, and repair. This design not only optimizes the production efficiency of the equipment but also improves its service life and ease of maintenance.

[0054] Furthermore, such as Figure 4 As shown, to improve the accuracy and safety of training, the rotating training mechanism is also equipped with a photoelectric sensor 24. This sensor 24 is installed inside the housing 1 and precisely engages with the output shaft of the drive assembly 21 via a locating pin 23 (such as a cylindrical pin). The locating pin 23 periodically contacts the sensor 24 as the output shaft of the drive assembly 21 rotates, thereby triggering the sensor 24 to take measurements. In this way, the sensor 24 can monitor the rotation angle and position of the output shaft of the drive assembly 21 in real time, precisely controlling the motion trajectory of the training mechanism. This technical feature effectively prevents motion errors caused by angular deviations, ensuring that the user remains in an ideal position and posture during training, thereby improving training effectiveness.

[0055] In addition, the rotational training mechanism includes a set of handle connectors 25, which are fixed to the ends of the output shafts at both ends of the motor and arranged in a reverse symmetrical manner (i.e., centrally symmetrical arrangement). This symmetrical layout allows the two first handles 26 to achieve a balanced training effect, making the user's arm movements more coordinated and natural during upper limb exercises. The first handles 26 and handle sleeves 27 are mounted on the handle connectors 25, ensuring a tight connection between the handles and the motor output shafts, preventing loosening or instability during exercise. This structural design not only improves the stability of the equipment but also provides a more comfortable grip, avoiding discomfort during training and further enhancing adherence and effectiveness of rehabilitation training.

[0056] Furthermore, such as Figure 7As shown, the upper limb training device also includes a sliding mechanism 5, used to achieve relative sliding between the upper limb training device and the lower limb training device to adapt to the training needs and physical conditions of different users. The sliding mechanism 5 includes a dovetail guide rail 51, a dovetail slider 52, a baffle 53, and a third locking element 54. The dovetail guide rail 51 extends horizontally and is securely fixed to the bottom surface of the second housing 15 through a threaded hole on its top surface. The dovetail slider 52 is slidably clamped on the dovetail guide rail 51 and can slide freely on the track of the guide rail 51. The dovetail slider 52 is fixedly connected to the lower limb training device. This sliding mechanism design allows the upper limb training device to be adjusted to the most suitable training position through relative sliding without changing the user's body position. When it is necessary to adjust the training angle or device position, the cooperation between the dovetail guide rail 51 and the dovetail slider 52 allows the upper limb training device to slide smoothly, ensuring that the device can be flexibly adjusted according to the user's specific needs.

[0057] To prevent the dovetail slider 52 from accidentally slipping during use, a baffle 53 is designed at one end of the dovetail guide rail 51. The baffle 53 effectively prevents the slider 52 from detaching from the guide rail 51, ensuring the safety and stability of the device. Furthermore, a threaded through hole is provided on the dovetail slider 52 for use with a third locking element 54. The third locking element 54 is typically a screw, which is threadedly installed on the dovetail slider 52. When the user adjusts the position and tightens the screw, the screw end passes through the threaded through hole and abuts against the dovetail guide rail 51. In this way, the clamping action of the screw fixes the dovetail guide rail 51 in the target position, achieving a locking effect and preventing the slider 52 from continuing to slide, thus ensuring that the user can complete the training in a comfortable posture. Moreover, this locking mechanism ensures the stability of the upper limb training device, especially during training with high mechanical loads, effectively avoiding discomfort or safety hazards caused by unstable device positioning.

[0058] Furthermore, such as Figure 5 As shown, the upper limb training device also includes a first angle adjustment mechanism 3. The core of the first angle adjustment mechanism 3 includes a first locking member 36, a first adapter plate 34, and a first turntable assembly. The first adapter plate 34 and the first turntable assembly are arranged coaxially in the horizontal direction. The first adapter plate 34 is connected to the first housing 14, while the first turntable assembly is connected to the second housing 15. This design allows the first housing 14 to rotate relative to the second housing 15, thereby changing the position and angle of the upper limb training device, and thus changing the layout of the two first handles 26 to achieve different training effects.

[0059] Specifically, when the first locking member 36 disengages from the first adapter plate 34, the first adapter plate 34 can rotate relative to the first turntable assembly in the vertical plane. This rotation causes the first housing 14 to rotate relative to the second housing 15 in the vertical plane, simultaneously changing the position of the two first handles 26. In the first position, the two first handles 26 are located on both sides of the drive assembly 21 along the horizontal direction, and at this time, the two handles perform circular motion in the vertical plane for training. If rotated to the second position, the two first handles 26 are located on both sides of the drive assembly 21 along the vertical direction, and the two first handles 26 perform circular motion in the horizontal plane. At this time, the first housing 14 rotates 90° relative to the second housing 15, realizing training in different directions and angles, thereby providing a more comprehensive exercise for the upper limb muscles.

[0060] When switching between the first and second positions, users can choose a suitable angle for upper limb training according to their training needs. It is particularly important to note that in the second position, users typically only need to grip the first handle 26 located above the motor for single-handed training, as the first handle 26 located below the motor is too low for effective gripping and exercise. When the first locking member 36 abuts against the first adapter plate 34, the connection between the first housing 14 and the second housing 15 is locked, preventing relative rotation and maintaining stable training in the current position, thus ensuring stability and safety during training.

[0061] Furthermore, the first turntable assembly consists of several key components, including a first limiting end cap 31, a first wear-resistant pad 32, a first turntable outer sleeve 35, a first wear-resistant bushing 37, and a first turntable fixing member 38. The first limiting end cap 31 has a central circular hole for cable passage and is connected to the first turntable fixing member 38 by screws, ensuring the overall structural stability. The first wear-resistant pad 32 is installed between the first limiting end cap 31 and the first adapter plate 34, effectively reducing friction and extending the equipment's service life. By adjusting the pressure of the screws on the first limiting end cap 31, the user can adjust the rotational damping between the first limiting end cap 31 and the first adapter plate 34, making the rotation process smoother and providing a more precise adjustment experience.

[0062] The first adapter plate 34 has threaded holes around its perimeter and is connected to the second cover plate 12 and the first housing 14 by screws, ensuring a secure connection. Its top surface has a mounting countersunk surface, and its bottom surface has an outwardly protruding cylindrical surface with a limiting flat part that matches the top of the first turntable outer sleeve 35. The first turntable outer sleeve 35 is cylindrical and has adjustment holes for the first locking element 36 (such as screws) and a stop step surface for the first wear-resistant bushing 37, thereby achieving a stable locking function and preventing changes in position from affecting training effectiveness. The first turntable fixing element 38 has a central through hole and threaded holes corresponding to the first limiting end cap 31, allowing the entire assembly to be securely fixed to the third cover plate 13 and the second housing 15.

[0063] A first wear-resistant bushing 37 is installed between the first turntable outer sleeve 35 and the first turntable fixing component 38. The bushing is made of a different material than other components, designed to reduce wear and improve durability, thereby ensuring the stability and accuracy of the equipment during long-term use. This design detail improves the durability and performance of the equipment, especially in situations where angle adjustments are frequent, effectively extending the equipment's service life.

[0064] In summary, the first angle adjustment mechanism 3 provided in this application, through its flexible structural design, enables precise adjustment of the upper limb training device at different angles and directions, greatly improving the adaptability and training effect of the equipment. Through meticulous component configuration and a clever locking mechanism, users can easily adjust the training angle according to their own needs, while ensuring safety, stability, and comfort during training. This innovative design not only enhances the functionality of the device but also strengthens its wide applicability in the field of rehabilitation training.

[0065] Furthermore, a first limiting member 33 is provided on the first adapter plate 34, and a first arc-shaped groove 31a is provided on the first turntable assembly to cooperate with the first limiting member 33. This structure allows the first limiting member 33 to slide within the first arc-shaped groove 31a when the first adapter plate 34 rotates relative to the first turntable assembly, thereby precisely controlling the rotation angle of the first housing 14 relative to the second housing 15. The length of the first arc-shaped groove 31a is 1 / 4 of the circumference, that is, when the first limiting member 33 slides from one end of the first arc-shaped groove 31a to the other end, the first housing 14 will rotate precisely 90° relative to the second housing 15. This design limits the rotation angle of the upper limb training device, ensuring that it will not exceed the preset angle range during adjustment. By limiting the rotation angle, unnecessary angle changes or unstable training postures can be effectively avoided during training, thereby ensuring that the user can maintain the optimal training position when training at different angles.

[0066] Furthermore, such as Figure 8As shown, the upper limb training device also includes a second angle adjustment mechanism 6. The core components of the second angle adjustment mechanism 6 include a second locking member 66, a second adapter plate 64, and a second turntable assembly. These components are arranged coaxially in the vertical direction. The second adapter plate 64 is connected to the second housing 15 via a dovetail slider 52, ensuring stable support and reliable motion performance. The second turntable assembly is connected to the lower limb training device, maintaining the stability and coordination of the overall system.

[0067] During operation, the second locking member 66 restricts or releases the constraint on rotation by contacting the second adapter plate 64. When the second locking member 66 releases contact with the second adapter plate 64, the second adapter plate 64 can rotate freely in the horizontal plane relative to the second turntable assembly, causing the upper limb training device to rotate relative to the lower limb training device. This rotation function allows the user to adjust the distance between the first handle 26 and the second handle 16 and themselves as needed, thereby optimizing the training posture and improving the training effect. For example, during upper limb training, the first handle 26 is closer to the user, while the second handle 16 is farther away; when not performing upper limb training, the user can rotate the upper limb training device 180° to bring the second handle 16 closer to themselves and the first handle 26 farther away, ensuring comfort and efficiency in different training modes.

[0068] To further improve the accuracy and safety of angle adjustment, a second limiting member 63 is provided on the second adapter plate 64, while a second arc-shaped groove 61a is formed on the second limiting end cover 61 of the second turntable assembly to cooperate with the second limiting member 63. The second limiting member 63 slides within the second arc-shaped groove 61a, limiting the rotation angle of the second adapter plate 64 and preventing excessive rotation of the device during adjustment. The length of the second arc-shaped groove 61a is 1 / 2 the circumference, meaning that when the second limiting member 63 slides from one end of the groove to the other, the upper limb training device will rotate precisely 180° relative to the lower limb training device, ensuring the accuracy and stability of angle adjustment. This design greatly improves the adaptability of the equipment and the user's sense of control, helping users easily achieve training at different angles and enhancing the diversity and effectiveness of training.

[0069] Similarly, the second turntable assembly includes several key components, such as the second limiting end cap 61, the second wear-resistant pad 62, the second turntable outer sleeve 65, the second wear-resistant bushing 67, and the second turntable fixing component 68. The second limiting end cap 61 has a central circular hole for cable passage, ensuring good connection and functional transmission of the internal components. The second wear-resistant pad 62 is installed between the second limiting end cap 61 and the second adapter plate 64. By adjusting the screw pressure on the second limiting end cap 61, the rotational damping can be precisely controlled, providing a smoother motion experience. The second adapter plate 64 has threaded holes for mounting the dovetail slider 52, ensuring a tight fit with the second housing 15 and enhancing system stability.

[0070] In addition, the top surface of the second adapter plate 64 is provided with a mounting countersunk surface, and the bottom surface has an outwardly protruding cylindrical surface, and is equipped with a limiting flat part that matches the top of the second turntable outer sleeve 65. The second turntable outer sleeve 65 is cylindrical and is equipped with an adjustment hole for the second locking member 66 (such as a screw) and a stop step surface for the second wear-resistant bushing 67, ensuring the tightness and stability of each component during rotation. The second turntable fixing member 68 is provided with a central through hole and a threaded hole corresponding to the second limiting end cap 61, ensuring the precise connection of each component and enhancing the stability and durability of the overall device.

[0071] To reduce friction and wear, a second wear-resistant bushing 67 is installed between the second turntable fixing component 68 and the second turntable outer sleeve 65. The bushing is made of a different material than other components. This design effectively reduces friction between components and extends the service life of the equipment. The bottom surface of the second turntable fixing component 68 is provided with a threaded hole, which connects to the mounting interface of the lower limb training device, ensuring a stable connection between the upper limb training device and the lower limb training device during adjustment.

[0072] In summary, the second angle adjustment mechanism 6, through its precise design and efficient structural configuration, not only provides angle adjustment functionality between the upper limb and lower limb training devices but also ensures precise coordination and stability of all components during training. Whether adjusting the angle during upper limb training or rest, users can easily switch training modes with simple operations, maximizing training effectiveness and comfort.

[0073] Furthermore, such as Figures 9 to 11As shown, the upper limb training device also includes a display mechanism 7, which comprises a base 71, a support frame 72, and a display screen 73. The base 71 is rotatably mounted on the surface of the housing 1 and can rotate horizontally. One end of the support frame 72 is hinged to the base 71, and the other end is connected to the display screen 73 via a ball joint 723. When subjected to external force, the base 71 can rotate to the desired angle. After the force is removed, it is stably fixed in a certain position by its own damping mechanism. The magnitude of this damping can be adjusted according to actual needs to ensure that the display screen 73 is stable and not easily shifted.

[0074] The support frame 72 itself features joint damping to maintain a stable posture, ensuring the display screen 73 is firmly fixed at the required angle or position during use. This design makes the display screen 73 more stable in different postures. Furthermore, the support frame 72 is foldable, significantly reducing its space occupation during storage and facilitating equipment storage and transport. This design not only optimizes the adjustment and operation of the display screen 73 but also improves the space utilization efficiency of the equipment, making it particularly suitable for training venues with limited space.

[0075] Specifically, the base 71 consists of several components, including a pressure cover 711, a third wear-resistant pad 712, a third adapter plate 713, a mounting base plate 714, and a support 715. The pressure cover 711 has countersunk holes and is connected to the mounting base plate 714 by screws. A cable pass-through hole is also provided in the center for easy cable routing and management. The third wear-resistant pad 712 is installed on both sides of the third adapter plate 713. Users can adjust the preload of the screws on the pressure cover 711 to change the rotational torque of the third adapter plate 713, thereby controlling the damping required for adjustment of the display screen 73. The mounting base plate 714 is fixed to the third cover plate 13 by screws, providing stable support for the entire base 71. The support 715 is installed on the mounting base plate 714 and has shaft holes for connection with other components, ensuring the stability of the base 71 and smooth rotation during use. Furthermore, the mounting base plate 714 has a pre-installed interface for connection with lower limb training devices, allowing users to directly install this display mechanism 7 onto other lower limb training devices for combined use.

[0076] The support frame 72 includes components such as a VESA conversion plate 721, a nut 722, a first support rod 724, a lock nut 725, a disc spring washer 726, an adjusting screw 727, and a second support rod 728. The VESA conversion plate 721 serves as a mounting platform for the display screen 73. Tightening the nut 722 presses the ball end of the ball joint 723, using friction to balance and support the display screen 73, and facilitating the adjustment of the display screen 73's rotation direction. The connections between the ball joint 723 and the first support rod 724, the first support rod 724 and the second support rod 728, and the second support rod 728 and the support 715 all employ the same fastening method: the disc spring washer 726 is installed on the contact surface of adjacent mounting components, and the lock nut 725 is installed on the adjusting screw 727. By continuously tightening these connections, the disc spring washer 726 deforms, thereby providing different damping effects through changes in friction. This design allows the damping of each connection point of the support frame 72 to be adjusted as needed during use, ensuring that the display screen 73 can be stably supported at any angle, while avoiding changes in the position of the display screen 73 due to vibration or external interference.

[0077] Through rotational adjustments at joints such as the VESA conversion plate 721 and ball joint 723, the ball joint 723 and the first support rod 724, the first support rod 724 and the second support rod 728, the second support rod 728 and the support 715, and the third adapter plate 713, the display screen 73 can be flexibly adjusted, fixed, and supported in any posture or angle. Furthermore, the folding function of the support frame 72 ensures effective space saving when not in use, allowing the entire device to be quickly unfolded and provide a stable display function when needed, and conveniently stored away when not in use, reducing the space occupied by the device. This design not only improves the operability and flexibility of the device but also effectively enhances the user experience, making the upper limb training device highly effective in various environments.

[0078] The specific usage process of the upper limb training device is as follows: First, the user can adjust the display screen 73 to a suitable viewing angle by rotating various rotating joints, such as the third adapter plate 713, the first support rod 724, the second support rod 728, and the ball joint connecting rod 723, thus ensuring the user has the best field of vision during training. According to training needs, the user can select the corresponding training mode and sequentially loosen the first locking member 36 and the second locking member 66 to position the first handle 26 appropriately. Applying force evenly, the user rotates the first angle adjustment mechanism 3 and the second angle adjustment mechanism 6 to adjust the upper limb training device to the designated training mode position. Next, by loosening the third locking member 54, the user can push or pull the sliding mechanism 5 to the appropriate position, and then tighten all locking members again to ensure the entire upper and lower limb training equipment is stable and fixed, guaranteeing safety and comfort during training.

[0079] For users requiring electrical stimulation training, after adjusting the angle and position of the device, the electrode cables must be connected to the terminal block 43, and the electrode pads must be attached to the corresponding muscle areas. Users can select a preset training mode on the display screen 73 and hold the first handle 26 to begin training. At this time, the motor and electrical stimulation mechanism 4 will begin executing the corresponding rehabilitation training movements according to system instructions, helping users recover neuromuscular function. If the user only needs electrical stimulation training, they can also loosen the second locking member 66, rotate the second angle adjustment mechanism 6, and interchange the positions of the first handle 26 and the second handle 16, using both hands to hold the second handle 16 to complete the electrical stimulation training. This satisfies different training needs while ensuring operational flexibility and comfort.

[0080] This training device features both active and passive training modes, as well as neuromuscular electrical stimulation, effectively combining the concepts of sports rehabilitation and physical therapy rehabilitation. It offers diverse training methods, including neuromuscular electrical stimulation, active training, passive training, active-passive switching training, and comprehensive training combining active and passive methods with neuromuscular electrical stimulation. Through these modes, users can choose the most suitable training method based on their individual rehabilitation needs, effectively improving the speed and effectiveness of motor function recovery.

[0081] Furthermore, the device boasts a high degree of adaptability. The extension length of the upper limb training device is adjustable, and the rotation angle between the vertical and horizontal planes can be flexibly switched, even achieving adaptive adjustments such as 180-degree horizontal rotation. These functions can be precisely adjusted according to different users' body types, needs, and rehabilitation progress, providing a personalized training experience and ensuring the device meets the diverse rehabilitation needs of users. In addition, the modular design simplifies disassembly and maintenance, reducing the difficulty of daily upkeep, extending the device's lifespan, and further enhancing its application value in medical and home rehabilitation.

[0082] Overall, the upper and lower limb training equipment provided in this application, through its expanded functions, diversified training modes, flexible adaptive adjustments, and convenient disassembly and maintenance design, fully meets the training needs of different users, and has significant advantages, especially in rehabilitation therapy. It not only optimizes the user experience and improves training effectiveness, but also promotes the concept of combining sports rehabilitation and physical therapy rehabilitation, providing efficient, convenient, and personalized rehabilitation training programs for different users.
