Abstract
Description
Technical Field
[0004] This application relates to the technical field of medical devices, and specifically to a lower limb progressive resistance rehabilitation training device for neurology patients. Background Art
[0005] During the rehabilitation process of neurology patients, progressive resistance training of the lower limbs is an important means to restore walking ability and improve lower limb muscle strength. Currently, there are various lower limb rehabilitation training devices on the market, which can be mainly divided into two categories: cycling training devices and lying training devices.
[0006] Cycling training devices are usually designed in a structure similar to a bicycle, and patients exercise their lower limbs through pedaling movements. Such devices can simulate the leg movement patterns during walking and help restore the lower limb coordination and muscle strength of patients. However, a significant drawback of cycling training devices is that they usually require patients to exercise in a sitting position and cannot accommodate patients who need to lie down for rehabilitation, such as patients who are unable to sit due to severe illness or mobility difficulties.
[0007] On the other hand, lying training devices are designed specifically for patients who cannot sit up. By adjusting the angle and resistance of the device, patients can also exercise their lower limbs while lying down. The advantage of such devices lies in their strong adaptability and the ability to cover a wider range of rehabilitation patient groups. However, lying training devices cannot accommodate patients who need to cycle for rehabilitation.
[0008] Therefore, the existing lower limb progressive resistance rehabilitation training devices have obvious limitations: cycling training devices cannot meet the needs of lying exercise, while lying training devices cannot meet the needs of cycling exercise. This singularity of the usage state limits the applicable range and training effect of the rehabilitation training device and poses an obstacle to the comprehensive rehabilitation of neurology patients.
[0009] Therefore, this application provides a lower limb progressive resistance rehabilitation training device for neurology patients to solve the above problems. Summary of the Invention
[0010] This application provides a lower limb progressive resistance rehabilitation training device for neurology patients, aiming to solve the obvious limitations of the existing lower limb progressive resistance rehabilitation training devices in the background art: cycling training devices cannot meet the needs of lying exercise, while lying training devices cannot meet the needs of cycling exercise. This singularity of the usage state limits the applicable range and training effect of the rehabilitation training device and poses an obstacle to the comprehensive rehabilitation of neurology patients, etc.
[0011] To achieve the above object, the present application provides the following technical solution: A lower limb progressive resistance rehabilitation training device for neurology patients, comprising a base, a damping pedal trainer disposed on the base, a seat disposed on the damping pedal trainer, and a grip disposed on the base; and further comprising a backrest;
[0012] An adjustment structure for adjusting the position of the backrest is provided on the damping pedal trainer. The adjustment structure includes a bracket fixedly disposed on the damping pedal trainer and hinged to the bottom of the backrest, a rotating shaft rotatably inserted into the bracket, driving gears symmetrically and fixedly sleeved on the rotating shaft, a driven gear rotatably disposed on the bracket and meshed with the driving gears, an internal tooth groove opened at the bottom of the backrest and meshed with the driven gear, and a driving member for driving the rotating shaft to rotate. During cycling exercise, the driving member drives the rotating shaft and the driving gears to rotate clockwise, the driving gears drive the driven gear to rotate counterclockwise, the driven gear drives the internal tooth groove and the backrest to rotate clockwise until the backrest rotates to the angle required by the patient and then stops. Then the patient can sit on the seat, hold the grip with the hand, and pedal the damping pedal trainer to perform rehabilitation training on the lower limbs of the patient. When the patient is training in bed, the driving member drives the rotating shaft and the driving gears to rotate counterclockwise, the driving gears drive the driven gear to rotate clockwise, the driven gear drives the internal tooth groove and the backrest to rotate counterclockwise until the top of the backrest abuts against the base and then stops. Then the device is placed on the bed, so that the folded backrest contacts the bed board to improve the stability of the device when placed on the bed. Then the patient's buttocks contact the seat to increase the force applied to the lower limbs of the patient and further improve the exercise effect when the patient is lying down.
[0013] Preferably, for the convenience of assembling the backrest and the bracket: a U-shaped groove is opened at the top of the bracket, the bottom of the backrest is clamped in the U-shaped groove, and rotating rods fixedly connected to the backrest are symmetrically and rotatably inserted into the top of the bracket. The combined design of the U-shaped groove and the rotating rods ensures the stability and accuracy of the backrest during assembly and prevents accidental movement or loosening of the backrest during the training process.
[0014] Preferably, for ensuring the stability of the folded backrest: a card slot for clamping and cooperating with the top of the backrest is opened at one end of the base away from the grip. The clamping and cooperating method simplifies the fixing process of the backrest, eliminates the need for additional fixing parts or tools, and reduces the operation difficulty and complexity.
[0015] Preferably, the driving member includes a worm gear fixedly sleeved on the rotating shaft, a worm rotatably inserted on the bracket and meshed with the worm gear, and a plum blossom plate fixedly connected to the end of the worm. The cooperation between the worm gear and the worm can form self-locking to ensure the stability after adjustment. A specific meshing relationship is adopted between the worm gear and the worm, and the rotation of the worm drives the rotation of the worm gear, thereby realizing the rotation of the rotating shaft. The design of the plum blossom plate enables users to easily perform the rotation operation without using additional tools or equipment, reducing the operation difficulty and complexity.
[0016] Preferably, to improve the comfort of using the backrest: an elastic pad is fixedly arranged at one end of the backrest close to the seat. The elastic pad is made of a soft and elastic material, such as high-density sponge, memory foam or latex, etc. These materials not only have good resilience and durability, but also can be adaptively adjusted according to the patient's body shape and posture, so as to provide more fitting support.
[0017] Preferably, to improve the stability of the support for the bracket: a support plate fixedly connected to the base and the damping pedal trainer is fixedly connected to the lower end of the bracket. The support plate is fixedly connected to the lower end of the bracket by welding to ensure that it will not loosen or fall off during use.
[0018] Preferably, to reduce the friction between the base and the ground: shock-absorbing pads are inserted at the ends of the base. The shock-absorbing pads are made of a soft and elastic material, such as rubber, silicone or high-density sponge, etc. These materials not only have good shock-absorbing performance, but also can be adaptively adjusted according to the unevenness of the ground, so as to provide more stable support.
[0019] Preferably, to improve the stability of the backrest when leaning: a reinforcement structure for improving the stability of the backrest is arranged on the backrest. The reinforcement structure includes a first hinge plate symmetrically hinged at the top of one end of the backrest away from the seat and a second hinge plate hinged at the end of the first hinge plate. The end of the second hinge plate is fixedly sleeved on the rotating rod. The reinforcement structure significantly improves the stability of the backrest during the patient's cycling process through the design of triangular support, reducing the shaking and tilting caused by external forces. The stable backrest design ensures the safety and comfort of the patient during the training process, which helps to improve the training effect.
[0020] The present invention integrates two modes of cycling training and lying training, meeting the needs of patients in different rehabilitation stages and improving the diversity and flexibility of training. The adjustable structure design of the backrest can ensure stable support during cycling training to prevent patients from falling. At the same time, in the lying training mode, the folded backrest increases the contact area between the device and the bed surface, improving stability. The designs of the seat and backrest conform to ergonomics, ensuring that patients can maintain a comfortable posture during training and reducing unnecessary physical burdens. The device has a compact structure, is easy to operate and maintain, and is suitable for use in various environments such as homes and hospitals, providing patients with a convenient and efficient rehabilitation training tool.
[0021] The reinforcement structure of this application, through the design of triangular support, significantly improves the stability of the backrest during the patient's cycling process, reducing shaking and tilting caused by external forces. The stable backrest design ensures the safety and comfort of patients during training, contributing to improving the training effect. The reinforcement structure is installed on the rotating rod. When the position of the backrest is adjusted through the adjustment structure, the reinforcement structure can also be adjusted synchronously, achieving the effect of linkage drive. This design not only simplifies the operation steps but also improves the flexibility and applicability of the training device. Brief Description of the Drawings

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0032] Embodiment 1
[0033] This embodiment provides a lower limb progressive resistance rehabilitation training device for neurology patients, as Figures 1-7 shown. The training device includes a base 1, a damping pedal trainer 2 arranged on the base 1, a seat 3 arranged on the damping pedal trainer 2, and a grip 4 arranged on the base 1; it also includes a backrest 5;
[0034] The damping pedal trainer 2 is provided with an adjusting structure 6 for adjusting the position of the backrest plate 5. The adjusting structure 6 includes a bracket 61 fixedly arranged on the damping pedal trainer 2 and hinged to the bottom of the backrest plate 5, a rotating shaft 62 rotatably inserted into the bracket 61, a driving gear 63 symmetrically and fixedly sleeved on the rotating shaft 62, a driven gear 64 rotatably arranged on the bracket 61 and meshed with the driving gear 63, an internal tooth groove 65 opened at the bottom of the backrest plate 5 and meshed with the driven gear 64, and a driving member 66 for driving the rotating shaft 62 to rotate. Through the adjusting structure 6, the position of the backrest plate 5 can be adjusted, so that the backrest plate 5 can be used as a backrest during cycling. When the patient leans backward during cycling, the backrest plate 5 can play a protective role to prevent the patient from falling. At the same time, when the patient lies in bed, by folding the backrest plate 5 so that the top of the backrest plate 5 abuts against the bracket 61, the folded backrest plate 5 can increase the contact area between the device and the bed board, improving the stability of the device when it is placed on the bed again. The folded backrest plate 5 can be used to place the device on the bed for the patient to exercise in bed. During exercise, the patient's buttocks can also contact the seat 3, increasing the force exerted by the patient's lower limbs and further improving the exercise effect when the patient lies down. During cycling exercise, the driving member 66 drives the rotating shaft 62 and the driving gear 64 to rotate clockwise, the driving gear 64 drives the driven gear 63 to rotate counterclockwise, the driven gear 63 drives the internal tooth groove 65 and the backrest plate 5 to rotate clockwise until the backrest plate 5 rotates to the angle required by the patient and then stops. Then the patient can sit on the seat 3, hold the handle 4 with the hand, and pedal the damping pedal trainer 2 to perform rehabilitation training on the patient's lower limbs. When the patient exercises in bed, the driving member 66 drives the rotating shaft 62 and the driving gear 64 to rotate counterclockwise, the driving gear 64 drives the driven gear 63 to rotate clockwise, the driven gear 63 drives the internal tooth groove 65 and the backrest plate 5 to rotate counterclockwise until the top of the backrest plate 5 abuts against the base 1 and then stops. Then the device is placed on the bed, and the folded backrest plate 5 contacts the bed board to improve the stability of the device when it is placed on the bed. Then the patient's buttocks contact the seat 3, increasing the force exerted by the patient's lower limbs and further improving the exercise effect when the patient lies down.
[0035] For the convenience of assembling the backrest 5 and the bracket 61: A U-shaped groove 611 is formed at the top of the bracket 61, the bottom of the backrest 5 is snap-fitted into the U-shaped groove 611, and rotating rods 612 symmetrically rotatably inserted into the top of the bracket 61 and fixedly connected to the backrest 5. The combined design of the U-shaped groove 611 and the rotating rods 612 ensures the stability and accuracy of the backrest 5 during assembly, preventing accidental movement or loosening of the backrest 5 during training. Specifically, a U-shaped groove 611 is formed at the top of the bracket 61, and its shape and size match the bottom of the backrest 5. During assembly, simply snap the bottom of the backrest 5 into the U-shaped groove 611 to achieve preliminary fixation. The rotating rods 612 are symmetrically rotatably inserted into the top of the bracket 61 and fixedly connected to the backrest 5. By rotating the rotating rods 612, the angle of the backrest 5 can be adjusted to meet the training needs of different patients. At the same time, the rotating rods 612 also play a role in further fixing the backrest 5, preventing accidental movement or loosening of the backrest 5 during training.
[0036] To ensure the stability of the backrest 5 after folding: A clamping groove 11 for snap-fitting with the top of the backrest 5 is formed at one end of the base 1 away from the grip 4. The snap-fitting method simplifies the fixing process of the backrest 5, eliminating the need for additional fixing parts or tools, and reducing the operation difficulty and complexity. Specifically, a clamping groove 11 is formed at one end of the base 1 away from the grip 4, and its shape and size match the top of the backrest 5 after folding. In the lying training mode, when the backrest 5 is folded and abuts against the bracket 61, its top will naturally snap into the clamping groove 11 to form a tight fit.
[0037] The driving member 66 includes a worm gear 661 fixedly sleeved on the rotating shaft 62, a worm 662 rotatably inserted into the bracket 61 and meshed with the worm gear 661, and a plum blossom plate 663 fixedly connected to the end of the worm 662. The cooperation between the worm gear 661 and the worm 662 can form self-locking to ensure the stability after adjustment. A specific meshing relationship is adopted between the worm gear 661 and the worm 662. By rotating the worm 662, the rotation of the worm gear 661 is driven, and then the rotation of the rotating shaft 62 is achieved. Due to the spiral angle and tooth number design of the worm 662 and the worm gear 661, when the worm 662 stops rotating, the worm gear 661 will be subject to self-locking and cannot rotate by itself, thus ensuring the stability after adjustment and avoiding potential safety hazards caused by the shaking or displacement of the device during training. The design of the plum blossom plate 663 enables users to easily perform the rotation operation without using additional tools or equipment, reducing the operation difficulty and complexity. When it is necessary to adjust the position of the backrest 5, the user holds the plum blossom plate 663 and rotates the worm 662. The rotation of the worm 662 will drive the meshed worm gear 661 to rotate, and then the rotation of the rotating shaft 62 is achieved. Due to the spiral angle and tooth number design of the worm 662 and the worm gear 661, when the worm 662 stops rotating, the worm gear 661 will be subject to self-locking and cannot rotate by itself.
[0038] To improve the comfort of using the backrest 5: An elastic pad 51 is fixedly provided at one end of the backrest 5 close to the seat 3. The elastic pad 51 is made of a soft and elastic material, such as high-density sponge, memory foam or latex, etc. These materials not only have good resilience and durability, but also can be adaptively adjusted according to the patient's body shape and posture, so as to provide more fitting support. The elastic pad 51 is tightly connected to the backrest 5 through a specific fixing method (such as adhesive, screw or buckle, etc.) to ensure that it will not loosen or fall off during use. At the same time, the design of the fixing method also takes into account the need for easy disassembly and cleaning, so as to clean and maintain the elastic pad 51 regularly.
[0039] To improve the stability of the support for the bracket 61: A support plate 613 fixedly connected to the base 1 and the damping pedal trainer 2 is fixedly connected to the lower end of the bracket 61. The support plate 613 is fixedly connected to the lower end of the bracket 61 by welding to ensure that it will not loosen or fall off during use. At the same time, the support plate 613 is also firmly connected to the base 1 and the damping pedal trainer 2 to form an integral structure, enhancing the stability of the training device. The support plate 613 is made of a strong and durable material, such as steel plate, aluminum alloy or high-strength plastic, etc., to ensure that it can withstand various loads and impact forces during the training process.
[0040] To reduce the friction between the base 1 and the ground: Shock-absorbing pads 12 are inserted at the ends of the base 1. The shock-absorbing pads 12 are made of a soft and elastic material, such as rubber, silica gel or high-density sponge, etc. These materials not only have good shock-absorbing performance, but also can be adaptively adjusted according to the unevenness of the ground, so as to provide more stable support.
[0041] Embodiment 2
[0042] Different from Embodiment 1, in order to improve the stability of the backrest 5 when leaning: a reinforcement structure 7 for improving the stability of the backrest 5 is provided on the backrest 5. The reinforcement structure 7 includes a first hinge plate 71 symmetrically hinged to the top of the end of the backrest 5 away from the seat 3, and a second hinge plate 72 hinged to the end of the first hinge plate 71. The end of the second hinge plate 72 is fixedly sleeved on the rotating rod 612. Through the design of triangular support, the reinforcement structure 7 significantly improves the stability of the backrest 5 during the patient's riding process, reducing the shaking and tilting caused by external forces. The stable design of the backrest 5 ensures the safety and comfort of the patient during the training process, helping to improve the training effect. The reinforcement structure 7 is installed on the rotating rod 612. When the position of the backrest 5 is adjusted through the adjustment structure 6, the reinforcement structure 7 can also be adjusted synchronously, achieving the effect of linkage drive. This design not only simplifies the operation steps but also improves the flexibility and applicability of the training device. When the backrest 5 is subjected to external forces during the patient's riding process, the reinforcement structure 7 effectively disperses and offsets the impact of the external forces on the backrest 5 through the hinge action of the first hinge plate 71 and the second hinge plate 72, as well as the triangular support formed with the rotating rod 612. This triangular support structure not only improves the stability of the backrest 5 but also ensures the safety of the patient during the training process.
[0043] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent substitutions or changes, and should be covered within the protection scope of the present application.
