Abstract
The invention relates to a power-assisting trolley capable of climbing stairs. The power-assisting trolley comprises a telescopic frame and combined wheels. Each combined wheel comprises three runners evenly distributed in the circumference direction and a supporting frame connecting the three runners. A pushing handle capable of rotating, stretching and contracting is arranged at the tail of the frame. Front wheel frames which are capable of rotating and are positioned through spring pins are arranged on the two sides of the head of the frame respectively. Rear wheel frames are arranged on the two sides of the tail of the frame respectively. The combined wheels are arranged at the bottoms of the front wheel frames and the bottoms of the rear wheel frames respectively and connected with the front wheel frames and the rear wheel frames through the supporting frames. Rotating positioning devices are arranged between the combined wheels and the rear wheel frames. The frame can be horizontally placed when the power assisting-trolley climbs the stairs through adjustment on the wheel frames, and damage of objects due to sliding collisions is avoided. Meanwhile, during resting in the midway, supporting with strength is not needed, and therefore strength is saved.
