[0023] A wearable exoskeleton hand rehabilitation training device includes a back-of-hand fixation plate 1, a heating mechanism on the back-of-hand fixation plate 1, several strip-shaped through holes 2 corresponding to each finger on the back-of-hand fixation plate 1, sliders 3 slidably connected to each strip-shaped through hole 2, an exoskeleton connecting rod 4 hinged to the lower part of the slider 3, finger sleeves 5 on the exoskeleton connecting rod 4, a connecting rod 6 rotatably connected to the slider 3, a spring 7 fixedly installed on the connecting rod 6, a fixation plate 8 fixedly installed on the back-of-hand fixation plate 1, several knobs 9 rotatably connected to the fixation plate 8, several screws 10 rotatably connected to the other side of the fixation plate 8, the knobs 9 and the screws 10 fixedly connected, a sleeve 11 fixedly connected to the fixation plate 8 around the screws 10, a polygonal rod 12 slidably connected inside the sleeve 11, the polygonal rod 12 threadedly connected to the screws 10, and the polygonal rod 12 fixedly connected to the spring 7;

[0024] As described above, when in use, each finger is aligned with the exoskeleton connecting rod 4, and the finger sleeve 5 is put on the hand, with the back of the hand fixing plate 1 resting against the back of the hand; rotating the knob 9 causes the screw 10 to rotate, which in turn causes the polygonal rod 12 to move laterally, stretching the spring 7; if it is necessary to reduce the tension felt by the fingers and palm, the spring 7 is contracted; if it is necessary to increase the tension felt by the fingers and palm, the spring 7 is stretched.

[0025] As a technical optimization of this utility model, the heating mechanism includes a battery located in the back of the hand fixing plate 1. The back of the hand fixing plate 1 is provided with a charging port 13 corresponding to the battery. A cotton pad 14 is provided on the back of the hand fixing plate 1 corresponding to the wrist and the back of the hand. An electric heating wire is provided in the cotton pad 14. The electric heating wire is electrically connected to the battery. A switch 15 is provided on the back of the hand fixing plate 1. The switch 15 is electrically connected to the electric heating wire.

[0026] As described above, pressing the power switch 15 connects the power supply to the heating wire, and the battery supplies power to the heating wire, which in turn heats up. The heat is then transferred to the cotton pad 14 through the insulating material, heating the wrist and the back of the hand and improving comfort during cold seasons.

[0027] As a technical optimization of this utility model, a lifting ring 16 is fixedly connected to the back of the hand fixing plate 1;

[0028] As can be seen from the above description, the lifting ring 16 makes it convenient for users to carry and handle the item.

[0029] As a technical optimization of this utility model, the finger sleeve 5 is made of rubber material;

[0030] As can be seen from the above description, rubber materials can provide sufficient comfort for the fingers and reduce the discomfort caused by hard materials.

[0031] As a technical optimization of this utility model, the polygonal rod 12 has a regular hexagonal shape;

[0032] As can be seen from the above description, the regular hexagon can prevent the polygonal rod 12 from rotating, and this shape is also convenient to manufacture.

[0033] As a technical optimization of this utility model, the fixed plate 8 is provided with scale lines 17 corresponding to the knob 9;

[0034] As can be seen from the above description, scale line 17 represents the tension of the stretch length corresponding to spring 7. The recovery of the strength of the fingers and palm can be clearly seen through scale line 17.

[0035] As a technical optimization of this utility model, a protective plate 18 is fixedly installed on the back of the hand fixing plate 1 corresponding to the spring 7;

[0036] As can be seen from the above description, the protective plate 18 can isolate most of the spring 7 from the outside world, and can prevent the human body from directly contacting the spring 7, being clamped by the spring 7, and causing discomfort.

[0037] The working process of this utility model is as follows:

[0038] In use, align each finger with the exoskeleton connecting rod 4, slip the finger sleeves 5 onto the hand, and rest the hand back fixing plate 1 against the back of the hand. Rotate the knob 9; the scale line 17 allows for precise adjustment of the knob 9, causing the screw 10 to rotate and move the polygonal rod 12 laterally, stretching the spring 7. To reduce the tension felt by the fingers and palm, the spring 7 is contracted; to increase the tension, the spring 7 is extended. If the back of the hand and wrist feels cold, press the power switch 15 to connect the heating wire. The battery powers the heating wire, causing it to heat up. The heat is then transferred through the insulating material to the cotton pad 14, heating the wrist and back of the hand and improving comfort in cold weather.

[0039] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
