Description

Technical Field

[0001] This utility model relates to the field of rehabilitation equipment technology, specifically to an adjustable electrical stimulation exercise rehabilitation device. Background Technology

[0002] An electrical stimulation rehabilitation device is a device that uses electrical stimulation to send low-frequency electrical stimulation adapted to movement to the peripheral nerves of multiple target muscles or muscle groups, causing the corresponding muscle groups to contract and control the muscles to perform periodic movements of the upper and lower limbs, thereby enabling motor relearning after nervous system injury.

[0003] For example, Chinese patent CN117018453B discloses a central and peripheral stimulation device that applies electrical stimulation to the patient's target muscles through a stimulation module and assists the patient in making corresponding movements through an external auxiliary module, thereby achieving neuromodulation therapy.

[0004] However, the external auxiliary modules of some current rehabilitation equipment have relatively complex structures; while some simple auxiliary modules can only drive patients to perform relatively simple movement paths, and it is difficult to modify the movement paths easily.

[0049] In this embodiment, when the connecting assembly 51 and the adjustable combination assembly 52 are working normally, the upper connecting plate 512 slides within the first sliding sleeve 521 to adjust the length of the upper connecting plate 512 between the first sliding sleeve 521 and the first support arm 2, and then the upper connecting plate 512 and the first sliding sleeve 521 are locked together by the locking bolt 523; the lower connecting plate 513 slides within the second sliding sleeve 522 to adjust the length of the lower connecting plate 513 between the second sliding sleeve 522 and the second support arm 3, and then the lower connecting plate 513 and the second sliding sleeve 522 are locked together by the locking bolt 523; the electric push rod 6 drives the second support arm 3. The second support arm 3 moves the first support arm 2. The second support arm 3 moves the lower connecting plate 513 through the mounting block 422 and the extension block 514. The first support arm 2 moves the upper connecting plate 512 through the mounting block 422 and the extension plate 511. By changing the length between the upper connecting plate 512 and the lower connecting plate 513 and the first support arm 2 and the second support arm 3, the movement trajectory of the upper connecting plate 512 and the lower connecting plate 513 is changed, thereby adjusting the movement trajectory of the first support arm 2 and the second support arm 3, and thus changing the movement trajectory of the user's arm. The user can then train on various movement trajectories.
