摘要

The aid has a loading area (4) comprising a height adjustment mechanism composed of reduction gear motor. The reduction gear motor propels two gear wheels to move the loading area up and/or down by screwing movements. A detection device continuously detects the speed of a user in order to adjust the speed between the shopping aid and the user. A charging device charges a lifting device's battery (2) or auxiliary drive's battery (3) in the aid. An accident avoidance unit avoids the accidents with the shopping aid, where the shopping aid recognizes whether the user contacts with a handle.
