Description

Technical Field

[0001] This utility model relates to the field of children's limb rehabilitation training technology, and in particular to a children's active and passive limb rehabilitation training device. Background Technology

[0002] Existing active and passive rehabilitation training devices for children are mostly based on the design of adult rehabilitation equipment. They are mostly open structures, and the training involves repetitive operations. The training mode is monotonous and boring, and children are easily distracted by external factors. Their attention span is short, and the monotonous mechanical repetition can easily cause children to resist, resulting in reduced compliance with rehabilitation training and affecting its effectiveness. At the same time, although the open structure design makes it easy to observe, children are prone to falls and injuries during active and passive training due to lack of coordination, loss of balance, or other accidents. Summary of the Invention

[0003] To address the problem of limited training modes in existing systems, this invention provides a children's active and passive limb rehabilitation training device. By constructing a shell around the main body and seat of the active and passive rehabilitation training device, and setting up two training modes (Training Mode 1 and Training Mode 2) for the upper limb training device, it offers two switchable training modes. Simultaneously, it transforms rehabilitation training into a "driving mode," reducing children's resistance to repetitive rehabilitation training and improving their enthusiasm and cooperation during training.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A pediatric limb active and passive rehabilitation training device includes a main body and a seat. The seat is disposed on one side of the main body and is used to assist the patient in sitting during active and passive rehabilitation training. The main body includes a lower limb training device, an upper limb training device, and a display screen. The lower limb training device is used for rehabilitation training of the patient's lower limbs. A support is fixed to the upper part of the lower limb training device. The display screen and the upper limb training device are fixed to the support. A shell is fixedly disposed around the main body and the seat. The upper limb training device includes a switchable training mode one and a training mode two. A transmission device is fixed to the support and is used to drive training mode one or training mode two.

[0005] Furthermore, the housing has a vehicle-shaped structure, with doors rotatably connected to both sides. Through integrated design, the vehicle-shaped housing transforms rehabilitation training into a "driving mode," leveraging children's interest in vehicles to reduce resistance to repetitive rehabilitation training and increase their enthusiasm and cooperation.

[0006] Furthermore, a display screen is fixedly connected to the front of the housing. When children are training, the display screen plays a first-person perspective of the vehicle's driving process. Through the combination of the housing, the active and passive rehabilitation training device, and the display screen, "virtual-real interaction" is achieved, enhancing children's driving experience, improving their concentration and participation, and increasing the quality of rehabilitation training. The handle and turntable enable diverse upper limb training, promoting upper limb recovery and improving training effectiveness.

[0007] Furthermore, the first training mode is a handle, and the second training mode is a turntable. Through the design of the housing, handle, and turntable, two switchable training modes are provided. Simultaneously, the turntable and housing design transform rehabilitation training into a "driving mode," reducing children's resistance to rehabilitation training, increasing their enthusiasm and cooperation, achieving diversity in upper limb training, and improving training effectiveness.

[0008] Furthermore, the transmission device includes a primary transmission device, a secondary transmission device, and a tertiary transmission device. The primary transmission device is fixed to the bracket, and the handle is connected to the primary transmission device. The handle rotates through the primary transmission device. A connecting piece is also fixed to the bracket. The secondary and tertiary transmission devices are mounted on the connecting piece. The secondary transmission device is connected to the primary transmission device, and the tertiary transmission device is connected to the secondary transmission device. The turntable is connected to the tertiary transmission device. Through the transmission device, the rotation of the handle and the turntable is achieved, enabling children to perform passive rehabilitation training. Children can also actively rotate the handle or the turntable to perform rehabilitation training.

[0009] Furthermore, the primary transmission device includes a drive device, a first gear, and a second gear. The drive device is fixed on the bracket, the first gear is fixedly connected to the drive device, and the second gear is rotatably connected to the connector. The second gear meshes with the first gear for transmission.

[0010] Furthermore, the drive device is a dual-output shaft worm gear reducer motor, with the first gear fixed on one of the output shafts. There are two handles, each connected to one of the output shafts of the drive motor. The handles are rotated via a primary transmission device, enabling children to practice grasping, pushing, and pulling movements, thus promoting hand muscle and arm stretching.

[0011] Furthermore, the secondary transmission device includes a first bevel gear and a second bevel gear, the first bevel gear and the second bevel gear are coaxially connected, the second bevel gear is rotatably connected to a connecting member, and the second bevel gear and the first bevel gear mesh and transmit power.

[0012] Furthermore, the three-stage transmission device includes a connecting ring, a first connecting rod, and a second connecting rod. The connecting ring is coaxially connected to a second bevel gear. The first connecting rod is rotatably connected to the connecting ring. One end of the second connecting rod is rotatably connected to a connecting piece, and the other end is fixed to a connecting shaft. One end of the first connecting rod is rotatably connected to the connecting ring, and the other end is rotatably connected to the connecting shaft. The turntable is connected to the connecting shaft. By setting up the two-stage and three-stage transmission devices, the rotation angle of the turntable is limited, allowing patients to train their arm swings while avoiding secondary injuries such as ligament strains, muscle tears, or joint dislocations caused by excessive rotation.

[0013] Furthermore, the turntable is rotatably connected to the connector, and the turntable has a waist-shaped groove. The connecting shaft is disposed in the waist-shaped groove and slides within the waist-shaped groove.

[0014] The beneficial effects of this utility model through the above technical solution are: This invention provides two switchable training modes through the design of a handle and a turntable, increasing the diversity of upper limb training and solving the problem of monotonous training modes. The handle trains upper limb grasping, pushing, and pulling movements, promoting hand muscle and arm stretching. The turntable drives the upper limbs to swing left and right, training shoulder and elbow joint activity, improving core stability of the arm, and increasing the immersion in the "driving mode." This invention transforms rehabilitation training into a "driving mode" by using the turntable and a vehicle-shaped shell fixed to the outer periphery of the active and passive rehabilitation training device and seat. It leverages children's natural interest in vehicles, reducing resistance to repetitive rehabilitation training and increasing their enthusiasm and cooperation. Simultaneously, the vehicle-shaped structure creates a relatively independent space for children, providing a sense of security and preventing injuries from falls or contact with sharp objects due to uncoordinated movements, loss of balance, or other accidents during rehabilitation training.

[0015] This invention features a display screen on the front of the housing, which displays the first-person perspective of the vehicle's driving process during children's training. By combining the housing, the active and passive rehabilitation training device, and the display screen, "virtual-real interaction" is achieved, enhancing children's driving experience, improving their concentration and participation, and raising the quality of rehabilitation training.

[0016] This invention, through the setting of a primary transmission device, a secondary transmission device, and a tertiary transmission device, enables the rotation of the handle and limits the rotation angle of the turntable, training the patient's arm swing while avoiding secondary injuries caused by excessive rotation, such as ligament strains, muscle tears, or joint dislocations.

[0026] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: like Figures 1-7As shown, a pediatric limb active and passive rehabilitation training device includes a main body and a seat 6. The seat 6 is fixed to one side of the main body and is used to assist the patient in sitting during active and passive rehabilitation training. The main body includes a lower limb training device 7, an upper limb training device, and a display screen 3. The lower limb training device 7 is used for lower limb rehabilitation training, and a support 8 is fixed to its upper part. The display screen 3 and the upper limb training device are fixed to the support 8. In this embodiment, the lower limb training device 7 and the display screen 3 are existing displays used for lower limb training and displaying data related to upper and lower limb training, and therefore will not be described in detail here.

[0027] The active and passive rehabilitation training device and seat 6 are all surrounded by a housing 1, which is an integrated vehicle-shaped structure. Doors 2 are rotatably connected to both sides of the housing 1. This integrated design enhances the overall load-bearing capacity of the housing 1. A sponge or rubber layer is fixed to the edges of the housing 1 to improve safety. The vehicle-shaped housing 1 visually transforms rehabilitation training into a "driving mode," leveraging children's natural interest in vehicles to reduce resistance to repetitive rehabilitation training and increase their enthusiasm and cooperation. Simultaneously, the vehicle-shaped housing 1 creates a relatively independent and enclosed space for the child, providing a sense of security and preventing injuries from falls or accidental contact with sharp objects due to uncoordinated movements, loss of balance, or other unexpected events during rehabilitation training.

[0028] A display screen 21 is fixedly connected to the front side of the housing 1 opposite to the seat 6. In this embodiment, the display screen 21 is an existing curved screen that can play videos. When the child is training, the display screen 21 plays videos of the vehicle's first-person perspective driving process or other videos suitable for children to watch. Through the combination of the housing 1, the turntable 5 and the display screen 21, "virtual-real interaction" is realized, forming a linkage of visual, auditory and tactile senses, enhancing the child's driving experience, improving the child's concentration and participation, and improving the quality of rehabilitation training.

[0029] To enhance the diversity of upper limb training, the upper limb training device includes two switchable training modes: Mode 1 (handle 4) and Mode 2 (rotary disc 5). Rotating the handle 4 trains hand grasping, forward and backward pushing and pulling movements of the arm, promoting hand and arm exercise. Rotating the disc 5 causes the arm to swing left and right, training shoulder and elbow joint mobility, while also increasing the immersive experience of the "driving mode." A transmission device is provided between the handle 4 and the disc 5. This transmission device drives the handle 4 and the disc 5 for active and passive upper limb rehabilitation training. The transmission device is fixed to the support 8 and connects the handle 4 and the disc 5. The transmission device includes a primary transmission device, a secondary transmission device, and a tertiary transmission device. The handle 4 is mounted on the primary transmission device and rotates via it. The disc 5 is mounted on the tertiary transmission device, and its rotation is achieved by the primary transmission device driving the secondary and tertiary transmission devices.

[0030] The primary transmission device includes a drive unit 10, a first gear 9, and a second gear 12. In this embodiment, the drive unit 10 is a dual-output shaft motor, and there are two handles 4, which are detachably connected to the two output shafts of the drive unit 10. Specifically, each handle 4 is fixed with a support rod 11, which is bolted to the output shaft. The drive unit 10 drives the two handles to rotate in a circular motion. The drive unit 10 is a conventional dual-output shaft worm gear reducer motor, such as the invention patent CN118058947A. The first gear 9 is fixed on one of the output shafts of the drive unit 10, and a connector 19 is fixed on the bracket 8. The connector 19 has a rectangular cavity structure, and a side plate is fixed on one side of the connector 19. The second gear 12 is rotatably connected to the side of the connector 19, and the first gear 9 and the second gear 12 mesh and transmit power.

[0031] The secondary transmission device includes a first bevel gear 14 and a second bevel gear 15. The first bevel gear 14 and the second bevel gear 15 are disposed inside the cavity of the connector 19. The first bevel gear 14 and the second bevel gear 12 are coaxially connected. The second bevel gear 15 is rotatably connected to the connector 19. The second bevel gear 15 and the first bevel gear 14 mesh and transmit power.

[0032] The three-stage transmission device is located outside the connecting member 19. The three-stage transmission device includes a connecting ring 16, a first connecting rod 17, and a second connecting rod 18. The connecting ring 16 is located on the outside of the connecting member 19 opposite to the second bevel gear 15, and is coaxially connected to the second bevel gear 15. The first connecting rod 17 is rotatably connected to the connecting ring 16. One end of the second connecting rod 18 is rotatably connected to the side plate of the connecting member 19, and the other end is fixed to a connecting shaft 13. The turntable 5 is rotatably connected to the connecting member 19. Specifically, a pin is fixed in the middle of the turntable 5. A hole is opened on the connecting member 19 at the lower part of the three-stage transmission device. The pin of the turntable 5 passes through the hole and is suspended in the air. A nut is threaded onto the suspended end of the pin. The turntable 5 has a waist-shaped groove 20. The connecting shaft 13 of the first connecting rod 17 and the second connecting rod 18 passes through the waist-shaped groove 20 and is suspended in the air. A nut is connected to the suspended end of the connecting shaft 13, and the connecting shaft 13 slides within the waist-shaped groove 20. Through the setting of the two-stage and three-stage transmission devices, the rotation angle of the turntable 5 can be limited, which can prevent secondary injuries caused by excessive rotation, such as ligament sprains, muscle tears, or joint dislocations, while training the patient's arm swing.

[0033] When a child patient needs rehabilitation training, they enter the interior of the housing 1 through the door 2 of the housing 1. The patient sits on the seat 6 and places their feet on the foot pedals of the lower limb training device 7 to train their lower limbs. The patient can choose to train on the turntable 5 or the handle 4 as needed. After selecting one, the other can be removed for training.

[0034] When using handle 4 for training, after removing the nuts fixed to the pin and connecting shaft 13, pull the pin of turntable 5 out of the hole in connector 19, disassemble turntable 5, and have the child hold both handles 4 with their hands respectively. Start the drive device 10 to rotate the support rods 11 fixed to the two output shafts of the drive device 10. The support rods 11 drive the handles 4 to rotate, causing the child's hands to passively follow the rotation of the handles 4, thereby realizing the forward and backward movement of the child's arms. Alternatively, the patient can actively rotate the handles 4 for training.

[0035] When the turntable 5 is selected for training, the bolts fixed to the drive unit 10 are removed to disassemble the support rod 11 and handle 4. The pin of the turntable 5 is inserted into the hole of the connector 19. After the connecting shaft 13 is set in the waist groove 20, the suspended ends of the pin and the connecting shaft 13 are connected with nuts. The child holds both ends of the steering wheel and starts the drive unit 10. The drive unit 10 drives the first gear 9 and the second gear 12 to mesh and transmit power. The rotation of the second gear 12 drives the first bevel gear 14, which is coaxial with it, to rotate. The rotation of the first bevel gear 14 drives the second bevel gear 15 to rotate. The second bevel gear 15 drives the connecting ring 16 to rotate. The connecting ring 16 drives the first link 17 and the second link 18 to move, thereby moving the connecting shaft 13 of the first link 17 and the second link 18 within the turntable 5 and driving the turntable 5 to rotate. This allows the turntable 5 to rotate within a certain range, enabling the patient to swing their arms left and right, or for the patient to actively rotate the turntable 5 after holding it with both hands to achieve left and right arm swings, thus enhancing the stability of the arms.
