Description

Multifunctional passive following hanging bracket

Technical Field

The invention relates to the field of machinery, in particular to a hanging bracket for fixing an exoskeleton robot and walking along with the exoskeleton robot.

Background

The exoskeleton robot is used for rehabilitation or walking of the disabled with the lower limbs, the self weight of a user and the total weight burden of the exoskeleton robot are heavier during walking, the heavier burden can be caused to the user during walking, the weight reduction effect is realized after the support is used for lifting the user and the exoskeleton robot, the burden of the user is reduced, and the walking state, the heart rate of the user, the muscle burden or the spasm phenomenon is greatly improved.

Moreover, after the user wears the exoskeleton robot, the user still needs to be protected by a rehabilitation therapist or other service personnel to follow the exoskeleton robot so as to avoid the user from falling down or other emergencies when the user is unable to walk or other accidents occur.

In the above-mentioned cases, in case the user is unable to walk or needs a rest, the prior art does not present the presence of following cradles or displacement machines, specially equipped with seats.

Meanwhile, similar hangers are available in the prior art, such as chinese patent CN101791255B, with patent names: in the walking-aid exoskeleton robot system and the control method, the patent discloses a vertical lower limb rehabilitation training robot which is provided with a movable flat plate, an integral bracket, a lifting gravity center adjusting system, exoskeleton mechanical legs and a control system, the mechanical leg hip joint adjusting device disclosed by the robot comprises a width adjusting rack, a width adjusting rotating shaft, a width adjusting gear, a width adjusting guide rail, a width adjusting sliding block and a width adjusting handle, on one hand, the width adjusting device is manually adjusted and is not simple and convenient to operate, on the other hand, the width adjusting device only realizes width adjustment and does not realize longitudinal fluctuation adjustment of a user in the walking process, because the hip joints on both sides have wave-shaped fluctuation and no longitudinal adjustment during walking according to the general gait, the walking gait is strange and not normal.

Moreover, the system device is provided with the movable flat plate, only provides a walking space of a user on the flat plate, is boring and tedious, is important for the disabled of lower limbs, has vital mood and psychological factors, directly influences the rehabilitation mood of the user, cannot bring the real walking state and the viewing range of the user by walking in a narrow space, cannot really accord with the normal walking habit, and has certain influence on the rehabilitation.

In addition, as in chinese patent CN202459981U, the patent names are: the patent provides a following hanging bracket of a similar exoskeleton robot, and discloses a bottom support frame, an electric lifting column, a stand column with a bend, a suspension arm, a handrail mechanism and a lower limb exoskeleton connecting mechanism, but the handrail elbow of the patent realizes rotatable width adjustment, but the handrail elbow can certainly generate front and back influence on the position of the exoskeleton robot after rotating, in addition, synchronous width adjustment can not be realized, and when one side is adjusted too much, a roll phenomenon can occur. In addition, the supporting device is not provided with a longitudinal exoskeleton robot adjusting range, and normal walking gait is influenced.
