It is understood that the swing arm may be divided into a main swing arm 41 and a sub swing arm 42, and the main swing arm 41 and the sub swing arm 42 are hingedly connected to each other, so that the swing arm as a whole can swing different postures, so that the fixing member 44 can be fixed on the thighs of patients of different postures. Furthermore, the hip exercise mechanism 4 may also be a restraint member for restraining the waist of the patient, by changing the direction of the swing arm with respect to the movable frame 12 so that the link 43 is positioned above the waist of the patient, and the fixing members 44 of the hip exercise mechanisms 4 on both sides limit the position of the patient together, so that the base mechanism 1 can ensure that the patient can stably fit on the bed board when turning over.

In one embodiment, the hip exercise mechanism 4 and the sole exercise mechanism 3 are used in combination, the hip exercise mechanism 4 is used to lift the patient's thigh, and the sole exercise mechanism 3 is used to move the patient's calf and foot so that the patient's lower limb can be specifically exercised in a normal walking posture.

The working principle is as follows:

the movable bed board drives the patient to change from a lying state to a sitting state or an upright state through the pushing of the pushing cylinder 15, so that the feet of the patient can act on the pedal 33 of the sole exercising mechanism 3, and the movable assembly 32 can drive the feet of the patient to do elliptic motion through the pedal 33; and the hip joint exercising mechanism 4 can assist in pushing and limiting the motion state of the thigh of the patient so as to ensure that the motion posture of the patient conforms to the normal lower limb motion trail of the human body.

During the exercise of the patient, the cardiopulmonary function of the patient is monitored in a non-contact manner by the sensing board 23 of the monitoring assembly, so as to ensure that the body of the patient is in a state suitable for exercise during the exercise.

The technical effects are as follows:

1. in the embodiment of the application, the sole exercise mechanism and the hip joint exercise mechanism are designed through redesigning the exercise mechanism. The sole exercising mechanism enables the pedal to carry the bottom of the foot of a patient to do reciprocating elliptical motion based on the linear motion of the first movable block and the second movable block on the limiting seat, and the hip exercising mechanism is matched to assist and limit the motion track of the thigh of the patient to help the patient to realize lower limb motion training closer to the normal walking track, so that the lower limb rehabilitation training effect is improved more effectively.
