Description

Technical Field

[0001] This utility model belongs to the field of rehabilitation equipment, specifically the field of upper limb rehabilitation training equipment, and specifically relates to a push-type upper limb balance training vehicle. Background Technology

[0002] Rehabilitation training is a professional training process that effectively helps individuals restore physical function. Currently available medical rehabilitation training includes a wide variety of upper limb rehabilitation equipment, such as upper limb lifting machines, forearm rotation machines, and manual power bikes. These devices each have their own characteristics, but they are all designed to enhance upper limb muscle strength and improve joint mobility. However, for patients with upper limb dysfunction, restoring balance and coordination is equally important.

[0003] Currently, a variety of upper limb rehabilitation training devices have emerged on the market, such as upper limb pressing trainers, forearm rotation trainers, and manual power bikes, each with its own unique design features. Upper limb pressing trainers strengthen the muscles of the shoulder, chest, and arms by simulating pressing movements; forearm rotation trainers focus on restoring forearm rotation function, improving muscle and joint flexibility and coordination; and manual power bikes combine upper limb and trunk strength training, not only enhancing muscle strength but also promoting the recovery of cardiopulmonary function. These devices have achieved significant results in enhancing muscle strength and improving joint mobility, providing strong support for patient rehabilitation.

[0004] However, while these devices excel in strength recovery, they often neglect the restoration of balance and coordination. Balance and coordination are crucial for maintaining posture, performing fine motor skills, and preventing falls, especially in daily life; deficiencies in these abilities can severely impact a patient's ability to live independently and their quality of life. Therefore, there is an urgent need in the market for a new type of rehabilitation training device that comprehensively addresses the recovery of upper limb muscle strength, joint range of motion, balance, and coordination. This device should not only possess a high degree of personalization to adapt to the different rehabilitation needs of patients but also incorporate intelligent and interactive design to enhance the fun and effectiveness of training, thereby stimulating active patient participation and promoting their continuous progress. Utility Model Content

[0005] This invention addresses the technical challenge of providing rehabilitation training equipment that simultaneously addresses the recovery of upper limb muscle strength, joint range of motion, balance, and coordination. It offers a hand-push upper limb balance training cart. By creating a weight difference between the two sides of the cart, it stimulates continuous force output on the weaker side of the patient's upper limb, maintaining the cart's balance during movement and achieving highly effective training. Furthermore, voice interaction during training enhances its enjoyment.

[0006] The technical solution adopted by this utility model is as follows: a hand-push upper limb balance training vehicle is provided, including a frame. The upper part of the frame integrates a level sensor, a controller, a voice player and a battery. The upper part of the frame is also hinged with a support arm, and the free end of the support arm is hinged with a handle. The lower part of the frame is rotatably equipped with a balance wheel and an auxiliary wheel. The auxiliary wheel is symmetrically arranged on both sides of the balance wheel and has a degree of freedom of lifting. The sides of the balance wheel are also provided with counterweight mounting positions.

[0007] During rehabilitation training, counterweights are placed in the mounting positions on both sides of the frame to adjust the weight difference, making the training cart heavier and tilting it towards the side where the patient's hand strength is weaker. When the patient pushes the cart using the handles and support arms, they need to maintain balance, requiring upper limb exertion to train the weaker side. By adjusting the weight difference, the training intensity can be controlled. The rehabilitation training is simple and effective. Furthermore, the auxiliary wheels on both sides of the frame provide additional support points, helping the patient maintain balance while pushing and facilitating familiarization with the training method. To improve patient confidence and enhance rehabilitation training, the height of the training wheels can be gradually increased as the patient's hand strength and training skills improve. This reduces the patient's reliance on the wheels and gradually enhances the effectiveness of rehabilitation training. During training, a level sensor monitors the balance of the training vehicle, and a voice prompt is played when the vehicle deviates to the side, allowing the patient to correct the deviation in time and enabling medical staff to protect the patient and ensure safety. The voice player also plays other auxiliary sound effects, such as encouraging and timing sounds, to boost the patient's confidence and ensure flexibility in use.

[0008] To further optimize this technical solution, the frame is a shell with an open bottom, the balance wheel is rotatably installed inside the shell and protrudes from the bottom of the shell; the counterweight mounting positions are set on both sides of the shell, and the front of the top of the shell integrates a level sensor, controller, voice player and battery with the help of a storage component, and the rear side is hinged to the support arm with the help of an assembly component.

[0009] The frame adopts a shell structure, which is simpler in structure, reduces the weight of the training vehicle, and improves its usability. The shell covers the balance wheel, increases aesthetics, and prevents damage to the balance wheel. The top surface of the shell provides mounting space for the level sensor, voice player, battery, and support arm, making the structure more compact and improving usability.

[0010] To further optimize this technical solution, the storage component includes a storage box fixedly installed on the top surface of the outer shell, and the level sensor, voice player and battery are all integrated inside the storage box.

[0011] The level sensor, voice player, and battery are all integrated into the storage box and mounted on the top surface of the casing, improving the aesthetics. The storage box also shields and protects the level sensor and other components, preventing damage and ensuring safe use.

[0012] To further optimize this technical solution, the assembly includes a fixing seat that is fixedly installed on the rear side of the top surface of the housing. The fixing seat is hinged to the support arm via a hinge shaft and locked to the support arm via a locking member.

[0013] The fixed base is fixedly mounted on the top surface of the housing, and the fixed base is hinged to the support arm via a hinge shaft, which facilitates the adjustment of the support arm angle to adjust the position of the handle. After locking it with a locking device, the handle is adjusted to a suitable position, making it convenient for patients to hold and push the training cart for training, thus improving its usability.

[0014] To further optimize this technical solution, the locking component includes two mating Allegro gears, which are fixedly installed on the fixed base and the support arm respectively. The hinge shaft coaxially passes through the two Allegro gears and is threadedly connected to a locking handle.

[0015] The outrigger is locked to the base by Arri gears. After the locking handle loosens the two Arri gears, the outrigger rotates along the base. The locking handle then engages the two Arri gears to lock the outrigger in place, thus ensuring reliability and preventing the outrigger from changing position arbitrarily, which would affect pushing training and make it safer to use.

[0016] To further optimize this technical solution, the counterweight mounting position includes a weight holder that is fixedly assembled with the left and right sides of the outer shell. The counterweight is detachably installed inside the weight holder. The cross-section of the weight holder is a "U" shaped structure. The top surface of the weight holder is open, and the outer wall of the weight holder has a notch for taking out and putting in.

[0017] The counterweights are placed on the left and right sides of the outer shell via weight holders to adjust the weight difference between the left and right sides of the training vehicle. The notches on the weight holders facilitate the removal and placement of the counterweights, ensuring flexibility of use.

[0018] To further optimize this technical solution, installation stations are evenly arranged on both sides of the outer shell along the height direction. The installation stations are symmetrically arranged and can be detachably installed with auxiliary wheels.

[0019] The auxiliary wheels are positioned along the outer casing via the installation station, resulting in a simple structure and flexible, easy-to-use operation.

[0020] To further optimize this technical solution, the balance wheel is a single wheel.

[0021] The single-wheel structure of the balance wheel reduces the size of the training vehicle and makes it easier to operate, thus improving training flexibility.

[0022] To further optimize this technical solution, the grip is a gear handle that is hinged to the support arm.

[0023] The gear handle can be rotated and positioned, allowing patients to adjust the grip angle and improve the comfort of pushing the training.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. The outrigger is hinged to the fixed base, which makes it easy to adjust its angle on the fixed base, thereby adjusting the support height of the handle, making the pushing and running of the training cart more applicable. The outrigger and the fixed base are assembled with Arri gears, which can achieve rotational positioning and ensure the reliability of the outrigger. The handle at the free end of the outrigger is a gear handle, which can also be rotated and positioned to ensure the comfort of the patient when holding and pushing.

[0026] 2. When patients are doing push training, adjust the weights on both sides of the balance wheel according to their recovery status, so that the training cart is heavier on the side with weaker hand strength. Patients need to exert force to control the balance of the training cart, thereby training the side with weaker hand strength and improving its strength. The amount of training can be adjusted by adding or removing weights in the weight seat. The training method is simple and effective.

[0027] 3. During training, the level sensor and voice player integrated in the storage box on the top of the outer shell are powered by a rechargeable battery. The level sensor detects the balance of the training vehicle and issues a warning when it deviates to one side, allowing the patient to correct the deviation in time and enabling medical staff to protect the patient in time, ensuring safety. The voice player also emits other auxiliary sound effects, such as encouraging sound effects and timing sound effects, to enhance the patient's confidence and ensure flexibility of use.

[0028] 4. During training, the auxiliary wheels on the left and right sides of the outer shell provide additional support points for the training cart, helping patients maintain balance while pushing it, and helping them become familiar with the operation of the training cart and build their confidence. As the patient's hand strength increases and training skills improve, the installation height of the auxiliary wheels can be gradually increased, so that the patient reduces their dependence on the auxiliary wheels, can independently master the ability to push the cart for training, and improve the rehabilitation training effect.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0036] Please see the appendix Figure 1 Appendix Figure 2 A push-type upper limb balance training vehicle includes a frame, on which a balance wheel 2, a level sensor 11, a controller, a voice player 12, a battery 13, a support arm 3 and a handle 4 for pushing are mounted. The frame can be a shell 1 with an open bottom, which is simpler in structure than a frame structure and can reduce the weight of the training vehicle and improve its flexibility of use. The balance wheel 2 is mounted inside the shell 1 and protrudes from the bottom of the shell 1 and contacts the support surface. The support arm 3 is hinged to the rear of the top surface of the shell 1, and the handle 4 is hinged to the free end of the support arm 3. The patient pushes the balance wheel 2 by gripping the handle 4 and keeps the balance wheel 2 balanced, thereby achieving the training effect. Therefore, the balance wheel 2 can be designed as a single wheel to achieve the training purpose by avoiding the tipping of the single wheel.

[0037] Please see the appendix Figure 2 To enhance training effectiveness and relevance, counterweights 5 are placed on the left and right sides of the outer shell 1. By adjusting the weight difference between the left and right sides of the outer shell 1, the patient maintains the balanced pushing of the balance wheel 2, thereby increasing training intensity and effectiveness. The counterweights 5 are installed on the left and right sides of the outer shell 1. The counterweight installation positions include weight seats 10 fixedly installed on the left and right sides of the outer shell 1. The weight seats 10 have an open structure, and the outer side of the weight seats 10 is provided with a notch 1001 for easy access to the counterweights 5, making it more convenient to use. During rehabilitation training, the patient can fill the weight seats 10 with foam or airbags to hold the counterweights 5 firmly against the weight seats 10, preventing the counterweights 5 from shaking and affecting the training process and effectiveness.

[0038] Please see the appendix Figure 1-3To ensure patient safety during training, auxiliary wheels 6 are symmetrically mounted on the left and right sides of the outer shell 1. The auxiliary wheels 6 provide additional support points for the training cart, helping patients maintain balance while pushing it, building their confidence, and helping them become familiar with the operation of the training cart. As the patient's upper limb strength increases and training skills improve, multiple mounting positions 101 are provided on the left and right sides of the outer shell 1 along the height direction. By installing the auxiliary wheels 6 onto mounting positions 101 at different heights, the installation height of the auxiliary wheels 6 is gradually increased, reducing the patient's dependence on the auxiliary wheels 6, enabling them to independently master the stable pushing ability of the training cart, and ultimately get rid of their dependence on the auxiliary wheels 6, achieving a complete training effect. The mounting positions 101 can be threaded through holes set on the outer shell 1, and the auxiliary wheels 6 are fixed to the outer shell 1 by bolts. The structure is simple, easy to disassemble and assemble, and stable and reliable in use.

[0039] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 5 The training vehicle also integrates a level sensor 11 and a voice player 12. The level sensor 11 is connected to the voice player 12 via a controller. The controller can use a conventional 51 microcontroller to control the level sensor 11 to detect the stability of the balance wheel 2. When tipping occurs, the detection signal is transmitted to the controller and a prompt sound is played through the voice player 12, allowing medical staff to protect the patient in time. The voice player 12 can also play music and various prompt sounds to ensure flexibility of use. Both the level sensor 11 and the voice player 12 can be integrated into the storage box 7, which is fixedly installed on the top front side of the outer shell 1. The storage box also integrates a battery 13 to power the level sensor 11 and the voice player 12, ensuring flexibility of use. The storage box 7 shields and protects the integrated level sensor 11, voice player 12 and battery 13 to avoid damage and other risks, ensuring safety of use.

[0040] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 4To enhance the usability of the training vehicle, the outrigger 3 and handle 4 are hinged together for easy angle adjustment, thereby adjusting the patient's grip height on the handle 4 and improving usability. The outrigger 3 is hinged to the rear of the top surface of the outer casing 1 via a mounting base 8. The mounting base 8 is fixedly installed to the outer casing 1 and has a hinge shaft 801. The hinge shaft 801 is hinged to the outrigger 3. Both the mounting base 8 and the outrigger 3 are fixedly fitted with Arri gears 9, which control the support angle of the outrigger 3. 801 is coaxially connected to the Arri gear 9 and threaded to a locking handle 802. After the locking handle 802 loosens the two Arri gears 9, it is convenient to rotate the support arm 3 to adjust the angle. After the locking handle 802 is threaded to the hinge shaft 801, the two Arri gears 9 are pressed together, thereby fixing the position of the support arm 3. The handle 4 is adjusted to a suitable height for the patient to control. The handle 4 at the free end of the support arm 3 can be a gear handle, which can rotate and lock on the support arm 3 for the patient to grip comfortably, making the training vehicle universal for different patients.

[0041] The working principle of this push-type upper limb balance training cart is as follows: During rehabilitation training, based on the patient's height and arm grip height, the support arm 3 is rotated along the fixed seat 8 on the outer shell 1 to adjust the support height of the support arm 3 on the handle 4. Then, the handle 802 is locked so that the Arri gear 9 engages and locks, fixing the position of the support arm 3 and making it more comfortable for the patient to push the training cart. Before pushing the cart, the assembly position of the auxiliary wheel 6 and its auxiliary participation are adjusted according to the patient's rehabilitation progress. Counterweights 5 are placed in the weight seat 10 to adjust the weight difference between the left and right sides of the outer shell 1. For example, when training the strength of the patient's right hand, the weight on the right side of the outer shell 1 is increased to be greater than the weight on the left side. This causes the training cart to be unbalanced, requiring the patient to exert force to control the balance, thus achieving the training purpose of the weaker hand area. When the patient is practicing pushing the training cart while maintaining balance, the level sensor 11 and voice player 12 integrated in the storage box 7 on the top surface of the outer shell 1 are powered by the battery 13. The level sensor 11 detects the balance status of the training cart, and the voice player 12 issues a warning when the cart deviates to one side, allowing the patient to correct the deviation in time and enabling medical staff to protect the patient in a timely manner, ensuring the safety of use. In addition, the voice player 12 will also emit other auxiliary sound effects, such as encouraging sound effects and timing sound effects, to enhance the patient's confidence and ensure the flexibility of use.
