Clinical medicine shows that if the population with lower limb disability or weakness can maintain standing or even simple walking in a timely manner, it can promote the compensation or reorganization of nerve tissue function, coordinate joint muscle groups, improve motor ability, and improve or even restore walking function. And appropriate exercise will greatly improve physical and mental health, can effectively reduce phenomena such as depression and pessimism, and improve sleep quality. Therefore, how to assist patients in restoring the ability to stand and walk is an important content of clinical rehabilitation treatment.

After the user completes the transition from a standing position to a sitting position, the linear push rod motor Ⅰ21 can lift the lower end of the calf support rod 23 together with the user's calf to a certain height, so that the pedal 30 is lifted off the ground, facilitating wheeled movement.
[0050] A kind of allosteric behavior-assisted robot provided by the present invention has the following working principle:
[0051] When the user wears it and enters the assisted walking mode, the adjusting nut 20-4 is screwed out until it disengages from the thigh support rod 20-1, and the robot is in the exoskeleton state, as Figure 1 shown. The left and right legs serve as the swinging leg and the supporting leg respectively. The hip joint motor and the knee joint motor of the swinging leg drive the thigh 3 and the calf 4 to perform flexion and extension movements. After the foot of the swinging leg lands, it is converted into the supporting leg, and the other leg swings, realizing the robot to assist the user in walking.
[0052] As Figure 2 shown, when the robot switches from the exoskeleton state to the supporting state, the linear push rod motor Ⅰ21 and the linear push rod Ⅱ22 work. The top end of the linear push rod motor Ⅰ21 is hinged to the slider 20-3, and the end is hinged to the calf support rod 23. The push rod of the linear push rod motor Ⅰ21 extends upward, and the slider 20-3 drives the adjusting nut 20-4 to move to the fixed limit of the notch on the side of the thigh support bottom rod 20-1. The user screws in the adjusting nut 20-5 to fix the slider 20-3. The top end of the linear push rod motor Ⅱ24 is hinged to the wheel rod 26, and the end is fixedly hinged to the fixed end of the calf support rod 23. The push rod of the linear push rod motor Ⅱ24 extends downward until the front universal wheel 27 and the rear drive wheel 28 are firmly on the ground, and the deformation of the robot's supporting state mechanism is completed. When the user needs to switch between sitting and standing postures, the robot is in the supporting state, and the linear motors Ⅰ21 of the left and right legs expand and contract, and the supporting height can be adjusted according to the actual needs of the user, realizing the robot to assist the user in sitting up and standing up.
[0053] As Figure 3As shown, when the robot switches from the support state to the wheelchair state, the push rod of the linear push rod motor I 21 retracts. The telescopic support rod 25 has several fixed positions and can be adjusted to an appropriate seat height according to the actual needs of the user and then fixed by a pin, completing the deformation of the robot wheelchair state mechanism. When the user needs to move quickly, the linear push rod motor I 21 extends the push rod upward by a certain length. The push rod drives the sliding ends of the thigh support rod 20 and the calf support rod 23 to support upward by a certain height, so that the feet 8 of the robot are lifted off the ground, facilitating the wheeled movement of the robot in the wheelchair state and realizing the wheeled substitution function of the robot.
[0054] The present invention is applicable to patients with lower limb motor dysfunction, with a novel structure and reasonable design. Most of the overall structure is made of aluminum alloy material, which can reduce the overall weight of the robot. Through the deformation and reorganization of the mechanism, the mutual conversion of the exoskeleton state, support state, and wheelchair state of the robot is realized, integrating the functions of assisting walking, assisting sitting up, and wheeled substitution, meeting the usage requirements in their daily lives.
[0055] The above is only the implementation mode of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, expansions, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
