Description

Technical Field

[0001] This utility model relates to the field of robotic arms for assisting rehabilitation training, and in particular to a robotic arm device for assisting rehabilitation training. Background Technology

[0002] Assisted rehabilitation training is a training method designed to help patients restore their physical function. It encompasses various types, such as those for patients with injuries (e.g., muscle atrophy after a fracture) or diseases (e.g., limb movement disorders after a stroke). Assisted rehabilitation training may utilize various specialized equipment, such as rehabilitation training devices, which can precisely control parameters such as exercise intensity and frequency. At the same time, professional rehabilitation therapists play a crucial role, developing personalized training plans based on the patient's specific condition, including targeted training for muscle strength, joint range of motion, and balance.

[0003] When a patient's arm is injured, it is usually necessary to repeatedly bend the arm to increase the patient's control over it. However, it is usually necessary to control the bending angle each time so that the patient can complete the rehabilitation treatment gradually. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a robotic arm device for assisting rehabilitation training.

[0005] This utility model is achieved by the following technical solution: a robotic arm device for assisting rehabilitation training, comprising a rehabilitation mechanism, a massage mechanism and a main body mechanism, wherein the rehabilitation mechanism is located on the upper surface of the main body mechanism and the massage mechanism is located on the outer surface of the rehabilitation mechanism; The rehabilitation mechanism includes a folding plate, a movable support is rotatably connected to the bottom surface of the folding plate, a slider is rotatably connected to the end of the movable support, a lead screw is threaded to the inner wall of the slider, and a motor is fixedly connected to the end of the lead screw.

[0006] Through the above technical solution, the folding plate is rotatably connected to the movable bracket, the movable bracket is rotatably connected to the slider, and the slider is threadedly connected to the lead screw. By setting the output end of the motor to fix the lead screw, the motor can drive the lead screw to rotate. When the lead screw rotates, it will drive the slider threaded to the outer wall to move linearly, thereby driving the movable bracket to rotate. When the movable bracket rotates, it can drive the folding plate to move, thereby precisely controlling the bending angle of the rehabilitation patient's arm to achieve the effect of assisting rehabilitation.

[0007] As a further improvement to the above solution, the top end of the lead screw is rotatably connected to a mounting housing, and the outer wall of the mounting housing is provided with a sliding groove.

[0008] Through the above technical solution, the lead screw is rotatably connected to the mounting housing, and the outer wall of the mounting housing is provided with a sliding groove. By setting the protrusion on the side wall of the slider to slide inside the sliding groove, the sliding groove can provide guidance for the movement of the slider and limit the range of movement of the slider, thereby increasing the smoothness of the slider movement process.

[0009] As a further improvement to the above solution, the bottom surface of the folding plate is rotatably connected to a pneumatic support.

[0010] Through the above technical solution, the folding plate is rotatably connected to the pneumatic support. By setting the pneumatic support on the bottom surface of the folding plate, when the folding plate moves, the pneumatic support rotates and stretches synchronously with the folding plate. Thus, the pneumatic support can provide real-time support to the folding plate, prevent the folding plate from collapsing, and increase the stability of the overall equipment.

[0011] As a further improvement to the above solution, the massage mechanism includes a massage bracket, the outer wall of which has a positioning hole, and the inner wall of which is fitted with a mounting bolt.

[0012] Through the above technical solution, the outer wall of the massage bracket is provided with positioning holes, and mounting bolts are fitted into the positioning holes. By evenly opening multiple positioning holes on the outer wall of the massage bracket, and by cooperating with the mounting bolts in positioning holes of different heights, the positions of the mounting bolts and massage rollers can be adjusted. In this way, the position can be adjusted at will according to the arm circumference of the rehabilitation patient, thereby increasing the flexibility and versatility of the overall equipment.

[0013] As a further improvement to the above solution, a massage roller is rotatably connected to the outer wall of the mounting bolt.

[0014] Through the above technical solution, the mounting bolt is rotatably connected to the massage roller. By setting the massage roller on the outer wall of the mounting bolt, the massage roller can effectively massage the patient's arm during the bending process, promote blood circulation, relieve muscle fatigue, and further enhance the effect of rehabilitation training.

[0015] As a further improvement to the above solution, the main body structure includes a main body base plate, and a rubber pad is fixedly connected to the bottom surface of the main body base plate.

[0016] Through the above technical solution, the main body base plate is fixedly connected to a rubber pad. By setting a rubber pad on the lower surface of the main body base plate, the device can be prevented from sliding during rehabilitation training, ensuring the stability of the training, and reducing the impact of vibration generated during device operation on the ground and the surrounding environment.

[0017] As a further improvement to the above solution, a fixed bracket is fixedly connected to the upper surface of the main body base plate, and a sponge pad is fixedly connected to the upper surface of the fixed bracket.

[0018] Through the above technical solution, the main body base plate is fixedly connected to the fixed bracket, and the fixed bracket is fixedly connected to the sponge pad. By setting the sponge pad on the upper surface of the fixed bracket, a soft support surface can be provided for the patient's arm, thereby increasing the overall comfort of the device during use.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a folding plate rotatably connected to a movable support, which in turn rotatably connects to a slider. The slider is threadedly connected to a lead screw, and the lead screw is fixed to the output end of a motor. The motor drives the lead screw to rotate, causing it to move linearly. This rotation of the lead screw, which is threaded to the outer wall, drives the movable support to rotate, allowing precise control of the bending angle of the patient's arm for assisted rehabilitation. The lead screw is rotatably connected to a mounting shell, the outer wall of which has a groove. A protrusion on the side wall of the slider slides within this groove, guiding its movement and limiting its range of motion, thus increasing smoothness. A folding plate is rotatably connected to a pneumatic support, which provides real-time support to the folding plate, preventing collapse and increasing the overall stability of the device.

[0020] This invention features a massage bracket with positioning holes on its outer wall. These positioning holes are fitted with mounting bolts. By evenly distributing multiple positioning holes on the outer wall of the massage bracket, and by engaging the mounting bolts with positioning holes of varying heights, the positions of the mounting bolts and massage rollers can be adjusted. This allows for flexible adjustment based on the arm circumference of the patient, increasing the equipment's flexibility and versatility. The mounting bolts are rotatably connected to the massage rollers. By placing the massage rollers on the outer wall of the mounting bolts, the massage rollers can effectively massage the patient's arm when it is bent, promoting blood circulation, relieving muscle fatigue, and enhancing the rehabilitation training effect.

[0025] The top end of the lead screw 104 is rotatably connected to the mounting housing 106, and the outer wall of the mounting housing 106 is provided with a sliding groove 107.

[0026] The bottom surface of the folding plate 101 is rotatably connected to a pneumatic support 108.

[0027] The massage mechanism 2 includes a massage bracket 201. The outer wall of the massage bracket 201 has a positioning hole 204, and the inner wall of the positioning hole 204 is fitted with a mounting bolt 202.

[0031] The implementation principle of the robotic arm device for assisting rehabilitation training in this embodiment is as follows: A folding plate 101 is rotatably connected to a movable support 102, which is rotatably connected to a slider 103. The slider 103 is threadedly connected to a lead screw 104. The output end of a motor 105 is fixed to the lead screw 104, so the motor 105 can drive the lead screw 104 to rotate. When the lead screw 104 rotates, it drives the slider 103, which is threaded to the outer wall, to move linearly, thereby driving the movable support 102 to rotate. This allows for precise control of the bending angle of the patient's arm, achieving the effect of assisting rehabilitation. The lead screw 104 is rotatably connected to a mounting shell 106. The outer wall of the mounting shell 106 has a groove 107. The protrusions on the sidewall of the slider 103 slide inside the groove 107, providing guidance for the movement of the slider 103 and limiting its range of motion, thus increasing the range of motion of the slider 103. To ensure smooth operation, a folding plate 101 is rotatably connected to a pneumatic support 108. The pneumatic support 108 provides real-time support to the folding plate 101, preventing it from collapsing and increasing the overall stability of the device. The massage support 201 has positioning holes 204 on its outer wall, which are fitted with mounting bolts 202. Multiple positioning holes 204 are evenly distributed on the outer wall of the massage support 201. By cooperating with the mounting bolts 202 at different heights, the positions of the mounting bolts 202 and the massage rollers 203 can be adjusted according to the patient's arm circumference, increasing the device's flexibility and versatility. The mounting bolts 202 are rotatably connected to the massage rollers 203. The massage rollers 203, located on the outer wall of the mounting bolts 202, effectively massage the patient's arm when it is bent, promoting blood circulation, relieving muscle fatigue, and enhancing the rehabilitation training effect.
