Single-degree-of-freedom rehabilitation training device with elliptical output trail

Abstract

The invention discloses a single-degree-of-freedom rehabilitation training device with an elliptical output trail. The device comprises a supporting mechanism and a motion mechanism arranged on the supporting mechanism. The motion mechanism comprises an annular gear, a planetary carrier and a planetary gear. The annular gear with inner teeth is fixedly mounted on the supporting mechanism; the planetary carrier is rotationally mounted on the supporting mechanism; the planetary gear with outer teeth is rotationally mounted on the planetary carrier; a rotating shaft of the planetary carrier is collinear with the center axis of the annular gear; the planetary gear and the annular gear are meshed with each other. Motion of the rehabilitation training device in an elliptical trail can be realized, a single training mode in a circular motion trail is changed, lengths and positions of the long axis and the short axis of the elliptical trail can be adjusted according to demands of users, and accordingly training effects of the users are greatly improved.

Description

technical field [0001] The invention relates to rehabilitation training equipment, in particular to a single-degree-of-freedom rehabilitation training device whose output trajectory is an ellipse. Background technique [0002] At present, the number of hemiplegia patients in China is increasing day by day, and limb rehabilitation training has also become a research hotspot. The movement trajectories of the limb rehabilitation training devices commonly available on the market are all circular, and the training mode is relatively simple, which cannot meet the training requirements of patients. In addition, the long-term rehabilitation training process of a trajectory can only perform rehabilitation training on parts of the limbs, which cannot meet the overall training requirements, greatly reducing the effect of rehabilitation training, and a single training mode will also make the patient's training process difficult. boring. [0003] Therefore, it is particularly important...

The movement trajectories of limb rehabilitation training devices that are common in the market are all circular, and the training mode is relatively simple, which cannot meet the training requirements of patients

In addition, long-term rehabilitation training with one trajectory can only perform rehabilitation training on parts of the limbs, which cannot meet the overall training requirements, greatly reducing the effect of rehabilitation training, and a single training mode will also make the patient's training process difficult. boring
