DETAILED DESCRIPTION

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0027] Please refer to Figures 1-3 An upper limb rehabilitation device includes a base 1 and a cover plate 2 above the base 1. The base 1 is hollow inside and the top is covered by the cover plate 2. The cover plate 2 is provided with a horizontally placed movable cavity 3. The movable cavity 3 is a rectangular box. The surface of the movable cavity 3 is provided with a turntable 6 for placing an arm. The turntable 6 can move left and right along the movable cavity 3. The movable cavity 3 can move back and forth along the base 1. The movable cavity 3 and the turntable 6 operate simultaneously to drive the upper limb to extend and retract.

[0028] Please refer to the arm extension and retraction position. Figures 10-11 When in use, the arm (wrist and forearm) is placed on the turntable 6. Since the turntable 6 can move left and right along the movable cavity 3, the upper limb also swings left and right. In addition, since the movable cavity 3 can move back and forth on the base 1, when the turntable 6 moves left and right, the movable cavity 3 also moves back and forth. At this time, while the upper limb swings left and right, it can also extend and retract at the elbow joint, further improving the range of motion and angle of the patient's upper limb and accelerating the recovery process.

[0029] Please refer to Figures 4-5 The movable cavity 3 has supports 4 on both sides. Inside the movable cavity 3, there is a slider 35, a lead screw 32, and two optical shafts 33. The lead screw 32 passes through the slider 35 and is rotatably connected to the two supports 4. The lead screw 32 and the slider 35 are threaded together. The two optical shafts 33 are located on both sides of the lead screw 32. The optical shafts 33 pass through the slider 35 and are fixed at both ends between the two supports 4. The lead screw 32 and the optical shafts 33 are arranged parallel to each other. One of the supports 4 has a motor cover 5 on its outer side. The motor cover 5 contains a stepper motor. The output shaft of the stepper motor is coaxially connected to the lead screw 32. When the stepper motor runs, the lead screw 32 rotates, which drives the slider 35 to move left and right.

[0030] In addition, the surface of the movable cavity 3 is provided with a third sliding groove 34 that communicates with the interior. A rotating shaft 36 is provided above the slider 35. The rotating shaft 36 extends upward in the third sliding groove 34 and is connected to the turntable 6. The turntable 6 can rotate on the rotating shaft, which makes it easy for the turntable to adapt to the arm's extension and retraction angle. When the lead screw 32 rotates, the slider 35 will move left and right. At the same time as the slider moves left and right, the rotating shaft 36 and the turntable 6 at the top of the rotating shaft will move left and right along the third sliding groove 34. During use, the arm can swing left and right.

[0031] In this embodiment, since the patient's upper limb is uncontrollable or has a limited control angle, a handle 61 and an arm support plate 62 are provided on the surface of the turntable 6 to prevent the patient's upper limb from falling off the turntable during use. The surface of the arm support plate 62 is provided with an arc-shaped groove 63. When in use, the arm is placed in the arc-shaped groove 63, which plays a certain limiting role. A plurality of Velcro straps 64 for fastening the arm are provided on one side of the arc-shaped groove 63. When in use, the arm is placed in the arc-shaped groove 63, and then the palm extends out of the arm support plate to grasp the handle 61. Then, the plurality of Velcro straps 64 are fastened to further fix the arm and prevent it from falling off the turntable, thereby improving the rehabilitation exercise effect.

[0032] In this embodiment, it does not affect the patient's inability to grip the handle 61 due to a lack of hand gripping ability; during rehabilitation exercises, it is sufficient to simply limit and fix the arm.

[0033] Please refer to Figures 2-3 6-9 Furthermore, the cover plate 2 has a first sliding groove 21 perpendicular to the moving cavity 3 at the middle, and the cover plate 2 has a second sliding groove 22 parallel to the first sliding groove 21 on both sides, and the moving cavity 3 can move back and forth along the first sliding groove 21 and the second sliding groove 22.

[0034] The bottom surface of the movable cavity 3 is provided with two first support plates 31. The two first support plates 31 extend downward through the cover plate 2 at the first slide groove 21 (inside the base). The bottom of the two first support plates 31 is provided with a fixed rack 72. Below the rack 72 is a meshing transmission gear 71. A drive motor 7 is provided on one side of the gear 71. The drive motor 7 is a stepper motor and is fixed on the inner bottom surface of the base. After the drive motor 7 runs, it drives the movable cavity 3 to move back and forth along the first slide groove 21 through the cooperation of the gear 71 and the rack 72.

[0035] When in use, limit blocks can be set at both ends of the rack 72 to prevent the rack 72 from disengaging from the gear 71. In addition, the pulse frequency of the drive motor 7 can also be set to prevent the rack 72 from disengaging from the gear 71.

[0036] To ensure stable movement of the movable cavity 3, a second support plate 41 is provided at the bottom of both sides of the movable cavity 3. The second support plate 41 extends downward through the cover plate 2 at the second slide groove 22. A roller 42 is provided between every two second support plates 41. A guide rail 12 that cooperates with the roller 42 is provided in the base 1. When the movable cavity 3 moves back and forth, the roller 42 rolls in the guide rail 12. A support block 11 is also provided in the base 1. The guide rail 12 is fixed to the surface of the support block 11.

[0037] In other words, the arrangement of the first slide groove 21 and the second slide groove 22 allows the transmission components such as the rack 72 and the roller 42 to be hidden below the cover plate 2, ensuring that the area above the cover plate 2 is clean and tidy, and facilitating the extension and retraction of the arm.

[0038] In this embodiment, the stepper motor and drive motor 7 inside the motor housing 5 start running simultaneously to drive the arm to swing horizontally. The speed and direction of the two stepper motors are adjustable. When the stepper motor inside the motor housing runs, it drives the turntable 6 to move left and right. When the drive motor 7 runs, it drives the moving cavity to move back and forth through the cooperation of gears and racks. While the moving cavity moves back and forth, the rollers roll in the guide rail 12, thereby allowing the patient's arm to extend and retract, thus accelerating the recovery process.

[0039] Based on the above embodiments, both the stepper motor and the drive motor 7 inside the motor cover 5 are connected to an external power supply; in addition, the motor cover 5 and the base 1 are provided with heat dissipation slots and wire holes to facilitate motor heat dissipation; when in use, the entire base can be placed on a flat surface.

[0040] As a preferred option, hydraulic lifting outriggers are installed under the base 1 to accommodate different heights.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
