[0018] The ball storage area is located at the lower part of the slope.

[0019] Preferably, the box body and partition are made of wood.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model provides an assistive device for hand strength rehabilitation exercises for hemiplegic patients, which has the following beneficial effects:

[0022] 1. This assistive device for hand strength rehabilitation exercises for hemiplegic patients has multiple partitions forming a sliding track structure, which, together with a ball that can slide within the track, enables patients to complete training by pushing the ball even in the early stages of rehabilitation when they have no grip strength, effectively achieving the rehabilitation transition from "pushing" to "grasping".

[0023] 2. This assistive device for hand strength rehabilitation training for hemiplegic patients, by setting holes of different shapes and sizes on the side wall of the slide, can specifically train the patient's target recognition, precise positioning and fine operation ability, and exercise the flexibility and coordination of the hand, in conjunction with the actions of pushing, grasping and placing the ball.

[0024] 3. This assistive device for hand strength rehabilitation exercises for hemiplegic patients, by setting an electromagnetic magnetic plate at the bottom of the box and using it in conjunction with an iron ball, achieves the function of adjustable magnetic force for the sliding resistance of the ball. It can dynamically adjust the training difficulty according to the patient's rehabilitation progress and meet the needs of gradual exercise. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example:

[0032] Please see Figures 1-4 This embodiment proposes an assistive device for hand strength rehabilitation exercises for hemiplegic patients. Its main body is a box 1, which is a cuboid structure with an open top and multiple partitions 2 inside for separating the sliding path.

[0033] like Figure 1 As shown, the box 1 is provided with four partitions 2, and three slides 3 are separated between each pair of the four partitions 2 (the two outermost partitions 2 are close to the inner side wall of the box 1) to limit the sliding path of the ball 5. One or more side holes 4 are opened on the inner wall of the slides 3 as target holes for the ball 5 to slide into during training.

[0034] In this embodiment, one end of the partition 2 is connected to the inner wall of the box 1, and the other end is left with a gap between it and the inner wall of the box 1 to form a ball storage area. The ball storage area is used to store the ball 5. During training, the ball 5 starts from the ball storage area and enters the side hole 4 through the slide 3.

[0035] In this design, the width of the slide 3 can be set to be different, for example, the width can be gradually increased; the side holes 4 can also have different shapes and sizes, for example, they can be set to be circular, elliptical or trapezoidal.

[0036] In the initial stage of training, patients can use their hands to push the ball 5 along the slide 3 and slide it into the side hole 4 to gradually increase hand strength and achieve various primary training goals such as hand force exertion, directional control, and target guidance, laying the foundation for subsequent rehabilitation training.

[0037] As the patient's hand strength improves, the patient can grasp the ball 5 and slide it along the slide 3, accurately placing it into the side hole 4. This not only further exercises the grip strength of the hand, but also promotes the improvement of finger dexterity and coordination.

[0038] like Figure 4 As shown, a ramp surface 8 is formed on the inner bottom wall of the box 1, and the ball storage area is located at the lower part of the ramp surface 8. By setting the ramp surface 8, the ball 5 can automatically roll back to the starting position after training, which improves the continuity and convenience of training and facilitates repeated training and independent operation by patients.

[0039] In order to further control the training difficulty, in this embodiment, a bottom groove 6 is provided at the bottom of the box 1, and an electromagnetic magnetic plate 7 is fixedly installed in the bottom groove 6. The sphere 5 is an iron ball that can be attracted by magnetic force.

[0040] When the electromagnetic magnetic plate 7 is energized, it can generate a magnetic field, which applies an attractive force to the sphere 5, thereby increasing its sliding resistance. By adjusting the current of the electromagnetic magnetic plate 7, the strength of the magnetic force can be dynamically controlled, thereby achieving different training resistance settings to meet the needs of different training stages.

[0041] In this embodiment, the electromagnetic magnetic plate 7 is equipped with a PWM regulator, which can continuously adjust the magnetic force by adjusting the duty cycle of the current.

[0042] To ensure the safety and comfort of the exercise aids, in this embodiment, the box 1 and the partition 2 are preferably made of wood, which has good tactile feel, temperature adaptability and structural strength, and is suitable for daily use by hemiplegic rehabilitation patients.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
