Description

Technical Field

[0001] The present application relates to the technical field of rehabilitation devices, and in particular to a rehabilitation device. Background Art

[0002] Neurological diseases such as cerebral hemorrhage, brain trauma, and acute myelitis can cause hemiplegia and limb weakness in patients. Rehabilitation equipment, especially children's lower limb rehabilitation equipment, plays an extremely important role in limb function training and patient recovery. After the patient's condition stabilizes, they need to get out of bed as soon as possible to perform functional exercises to prevent muscle atrophy and joint contractures due to disuse, and promote the recovery of limb function. Generally, if a caregiver supports the patient to get out of bed for exercise, the patient will be highly dependent and can only rely on the caregiver's strength to walk forward, which is not conducive to the recovery of limb function. However, exercise with rehabilitation equipment can significantly improve limb muscle strength, coordination, and walking ability.

[0003] While existing pediatric lower limb rehabilitation equipment can provide effective rehabilitation, it remains stationary during use, making it boring for children, leading to shorter training sessions and poor rehabilitation outcomes. Furthermore, existing rehabilitation equipment is complex in structure. Utility Model Content

[0033] The present application provides a rehabilitation device.

[0034] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] like Figures 1 to 3As shown, the embodiment of the present application provides a rehabilitation device, which is mainly used for the rehabilitation of children's lower limbs. The rehabilitation device mainly includes a frame 1 and a driving wheel 2, a driving motor 3 and a pedal device 4 arranged on the frame 1. The driving motor 3 drives the driving wheel 2 to rotate to realize the movement of the rehabilitation device. The pedal device 4 includes a bracket 401, an elastic member 402, a pedal 403 and a sensor 404. The bracket 401 is connected to the frame 1, and the bracket 401 is used to provide an installation position for the elastic member 402, the pedal 403 and the sensor 404; one end of the elastic member 402 is connected to the bracket 401, and the other end is connected to the pedal 403, and can overcome the elastic force of the elastic member 402 under the action of an external force, that is, when a child uses the rehabilitation device for rehabilitation training, the child's foot needs to overcome the elastic force of the elastic member 402 to move the pedal 403 to achieve the purpose of training; the sensor 404 is set on the bracket 401, and can transmit a signal to the drive motor 3 when the pedal 403 moves, so as to drive the drive wheel 2 to rotate, thereby imitating a conventional children's bicycle, so that children can experience the joy of riding a children's bicycle when using the rehabilitation device for rehabilitation training.

[0036] Specifically, when a user uses the rehabilitation device for rehabilitation training, they step on pedal 403, causing pedal 403 to move against the elastic force of elastic member 402. During this movement, the information measured by sensor 404 changes, transmitting an electrical signal to the drive circuit, which then rotates drive wheel 2 to achieve movement of the rehabilitation device. Furthermore, each time sensor 404 transmits a signal to drive motor 3, it only assists drive wheel 2 for 2 to 5 seconds. To maintain continuous movement, the user needs to reciprocate and reciprocate pedal 403 to shift it, thus increasing the user's interest and improving the duration of their training.

[0037] It should be noted that the movement mode of the pedal 403 is not limited here, and the movement mode may be movement and / or rotation.

[0038] It should also be noted that the form in which the pedal 403 overcomes the elastic force of the elastic member 402 when the pedal 403 moves is not limited here. The pedal 403 can overcome the rebound force of the elastic member 402 or the tensile force of the elastic member 402 during the movement. Figure 2 When moving in the direction indicated by the arrow Z, when the elastic member 402 is arranged below the pedal 403, the pedal 403 overcomes the rebound force of the elastic member 402 when moving downward; and when the elastic member 402 is arranged above the pedal 403, the pedal 403 overcomes the tensile force of the elastic member 402 when moving downward.

[0039] It should also be noted that the type of sensor 404 is not limited here. The sensor 404 can be a photoelectric sensor, a pressure sensor, a position sensor, a speed sensor, etc., and can determine whether the drive motor 3 is moving by detecting whether the pedal 403 blocks the photoelectric sensor 404, or detecting the pressure applied to the elastic member 402, or detecting the position of the pedal 403, or detecting the change in the speed of the pedal 403. For details, see Figure 3 , turn on the rehabilitation device, then operate the gear part to select the speed and the resistance of the driving part 7, and then determine whether the sensor 404 is triggered. If triggered, the driving motor 3 drives the driving wheel 2 to rotate, and the driving wheel 2 drives the rehabilitation device to move. Then return to the judgment step to determine whether the sensor 3 is triggered again; if not triggered, return to the judgment step to determine whether the sensor 3 is triggered again.

[0040] Exemplarily, the driving motor 3 is a hub motor; the elastic member 402 is a spring.

[0041] The rehabilitation device of the above structure uses a drive wheel 2, a drive motor 3, and a pedal device 4. The user's foot acts on the pedal 403 in the pedal device 4, causing the pedal 403 to overcome the elastic force of the elastic member 402 and move. The sensor 404 located on the bracket 401 transmits a signal to the drive motor 3 when the pedal 403 moves. The drive motor 3 drives the drive wheel 2 to rotate to achieve movement of the rehabilitation device. The user's foot applies force to the pedal 403, which can promote limb function recovery. In order to keep the rehabilitation device moving during the rehabilitation process, the user needs to continuously act on the pedal 403, which increases the fun of the child's rehabilitation process and improves the rehabilitation effect. Moreover, the rehabilitation device has a simple structure and can effectively achieve lower limb rehabilitation.

[0042] In some embodiments, the rehabilitation device further includes a slide groove 5 and a sliding member 6 that slides along the slide groove 5. The slide groove 5 is provided on at least one of the footrest 403 and the bracket 401; the sliding member 6 slides along the slide groove 5 and is provided on at least the other of the footrest 403 and the bracket 401. In this way, when the user uses the rehabilitation device for training, when stepping on the footrest 403 to overcome the elastic force of the elastic member 402 and move, the footrest 403 will slide relative to the bracket 401 by providing the above-mentioned sliding connection slide groove 5 and sliding member 6, thereby preventing the footrest 403 from deviating during its movement relative to the bracket 401, ensuring the smooth movement of the footrest 403 during the rehabilitation process, and improving the safety of the rehabilitation device during the rehabilitation process.

[0043] In this embodiment, an optional implementation is provided, in which the slide groove 5 is provided on the footrest 403 , and the sliding member 6 is provided on the bracket 401 .

[0044] In this embodiment, another optional implementation is also provided, in which the slide groove 5 is provided on the bracket 401 and the sliding member 6 is provided on the pedal 403 .

[0045] In this embodiment, another optional implementation is provided, in which the footrest 403 is provided with a slide groove 5 and a sliding member 6, and the bracket 401 is provided with the sliding member 6 that is slidably connected to the slide groove 5 provided on the footrest 403, and is provided in the slide groove 5 that is slidably connected to the sliding member 6 provided on the footrest 403. This configuration can further improve the stability of the footrest 403 during movement.

[0046] In some embodiments, the sensor 404 is a photoelectric sensor, a pressure sensor, a position sensor, or a speed sensor. For example, when the sensor 404 is a photoelectric sensor, the pedal 403 will block the photoelectric sensor during movement, so that the light signal detected by the photoelectric sensor changes, and thus a signal is transmitted to the drive motor 3 to rotate the drive wheel 2 to achieve the movement of the rehabilitation device; when the sensor 404 is a pressure sensor, the pressure sensor is connected to the elastic member 402, and the pressure on the elastic member 402 will change during the movement of the pedal 403, so a signal is transmitted to the drive motor 3 to rotate the drive wheel 2 to achieve the movement of the rehabilitation device; when the sensor 404 is a position sensor, the position of the pedal 403 will change during the movement of the pedal 403, and the position sensor can detect the position information of the pedal 403, so a signal is transmitted to the drive motor 3 to rotate the drive wheel 2 to achieve the movement of the rehabilitation device; when the sensor 404 is a speed sensor, the speed of the pedal 403 will change during the movement of the pedal 403, and the position sensor 404 can detect the speed information of the pedal 403, so a signal is transmitted to the drive motor 3 to rotate the drive wheel 2 to achieve the movement of the rehabilitation device.

[0047] In some embodiments, multiple photoelectric sensors are provided in the direction of movement of the pedal 403. For example, taking three photoelectric sensors as an example, the arrangement positions of the three photoelectric sensors are as follows: Figure 2 Specifically, multiple photoelectric sensors 404 are provided to transmit photoelectric change information to the drive motor 3 multiple times during the movement of the pedal 403 overcoming the elastic force of the elastic member 402. This allows the drive motor 3 to drive the drive wheel 2 for a longer time as the pedal 403 moves a longer distance. As a result, the rehabilitation device can move a longer distance as the user drives the pedal 403 to move a longer distance.

[0048] For example, the movement direction of the pedal 403 is Figure 2 The direction is indicated by the arrow Z. It should be noted that the movable direction of the movable member can be a linear direction or a curved direction.

[0049] In some embodiments, the rehabilitation device further includes a driver 7 disposed on the bracket 401. The driver 7 is capable of driving the pedal 403 to overcome the elastic force of the elastic member 402 to adjust the initial position of the pedal 403 before movement. Specifically, a baffle connected to the driver 7 is provided. The driver 7 drives the baffle to move the pedal 403. This allows adjustment of the resistance of the pedal 403 in its initial position. After the pedal 403 is adjusted, the pedal 403 needs to overcome a greater elastic force of the elastic member 402 to move the same distance compared to before the adjustment. This allows adjustment of the rehabilitation resistance of the rehabilitation device, making the rehabilitation device suitable for users requiring different strengths, thereby improving the applicability of the rehabilitation device. Furthermore, multiple photoelectric sensors are disposed in the direction of movement of the pedal 403. When the pedal 403 is in different initial positions, the movement of the pedal 403 triggers the photoelectric sensors, thereby causing the rehabilitation device to move.

[0050] Exemplarily, the driving member 7 may be a stepping motor.

[0051] In some embodiments, the rehabilitation device further includes an adjustment assembly disposed between the frame 1 and the bracket 401 to adjust the relative position of the frame 1 and the bracket 401. Specifically, by providing the adjustment assembly to adjust the relative position of the frame 1 and the bracket 401, the position of the footrest 403 is aligned with the position of the user's foot, thereby improving user comfort and making the rehabilitation device suitable for users of a wider age range, height, and weight.

[0052] Exemplarily, the bracket 401 is rotationally connected to the frame 1 via a damping shaft, and the bracket 401 is rotated relative to the frame 1 to adjust the angle of the bracket 401 relative to the frame 1, and the provision of the damping shaft enables the bracket 401 and the frame 1 to maintain their positions after rotation; the bracket 401 and the frame 1 can also be connected via a rack and pinion, and the gear is moved relative to the rack to achieve position adjustment of the bracket 401 and the frame 1, and since the position adjustment is achieved via the rack and pinion, the bracket 401 and the frame 1 can also maintain their positions after movement.

[0053] In some embodiments, the adjustment assembly includes an adjustment hole, a connecting hole, and an adjustment member. The adjustment hole is provided on the bracket 401; the connecting hole is provided on the frame 1, and at least one of the adjustment hole and the connecting hole is provided with a plurality of holes; the adjustment member passes through the connecting hole and the different adjustment holes to adjust the angle of the bracket 401 relative to the frame 1. Exemplarily, the adjustment member is a pin, and through the different connection relationships between the adjustment hole and the connecting hole, the position and angle of the bracket 401 can be conveniently adjusted, that is, the position of the pedal 403 located on the bracket 401 can be adjusted. Such a setting can efficiently adjust the position and angle of the bracket 401 relative to the frame 1, improve the convenience of adjustment, and has a simple structure.

[0054] For example, one connection hole and multiple adjustment holes can be provided; multiple connection holes and one adjustment hole can be provided; multiple connection holes and multiple adjustment holes can be provided. The above three configurations can all achieve adjustment of the relative position and angle between the bracket 401 and the frame body 1.

[0055] In some embodiments, the rehabilitation device further includes a gear member electrically connected to the drive motor 3, which can adjust the power of the drive motor 3. For example, the gear member includes three gears: high speed, medium speed, and low speed. In the high speed gear, the higher the speed of the drive motor 3 when the pedal 403 moves the same distance, the farther the rehabilitation device moves in the same time. In the medium speed gear, the speed of the drive motor 3 when the pedal 403 moves the same distance is intermediate, and the distance the rehabilitation device moves in the same time is moderate. In the low speed gear, the lower the speed of the drive motor 3 when the pedal 403 moves the same distance, the closer the distance the rehabilitation device moves in the same time. By setting the gear member, the distance of movement of the rehabilitation device can be conveniently adjusted, thereby improving the convenience of adjusting the distance of movement of the rehabilitation device.

[0056] In some embodiments, the rehabilitation device further includes a fixing strap connected to the footrest 403. Specifically, since the rehabilitation device is suitable for children, children's feet are easily detached from the footrest 403 during use. Here, the fixing strap can be provided to fix the user's feet on the footrest 403, thereby improving the user's comfort during use.

[0057] Furthermore, the length of the fixing strap is adjustable to accommodate users with feet of different sizes and facilitate the fixing or releasing of the foot and the pedal 403 .

[0058] In some embodiments, the rehabilitation device includes driven wheels 8 connected to the frame 1, a seat 9, a backrest 10, and armrests. Specifically, preferably, at least two driven wheels 8 are provided to improve the stability of the rehabilitation device during movement; the seat 9 and backrest 10 are provided for the user to use, improving comfort during rehabilitation; and the armrests include a first armrest 11 for the caregiver to support and a second armrest 12 for the user to support. This configuration further improves the safety of the user when using the rehabilitation device.
