The invention relates to an external skeleton assisting
robot, in particular to a portable energy-
storage type external skeleton assisting
robot. The problems that an existing
lower limb external skeleton assisting
robot worn on the
human body is poor in assisting effect so that the loading capacity of the
human body can be reduced, the wearing comfort for the
human body is poor, the universality is poor, and the field environmental suitability is poor are solved. The portable energy-
storage type external skeleton assisting robot comprises the upper body back, the left leg and the right leg, and the left leg and the right leg respectively comprise a hip driving
system, a
thigh driving
system and a shank wearing
system. A hip joint energy-storage mechanism comprises a connecting base, a stretching rod, a second spring and a stopping sheet, and a first
bevel gear is meshed with a second
bevel gear. Each hip driving system comprises a second motor with a coder, a second
reducer, a third
bevel gear, a fourth bevel gear, a
thigh connecting rod, a
knee joint support, a
knee joint connecting plate, an angle sensor, a series connection elastic combination body, a
knee joint gearbox body, a knee joint shaft and an end cover. The portable energy-
storage type external skeleton assisting robot is suitable for being worn outdoors for walking assisting.
