OBSTACLE-CROSSING ACCOMPANYING ROBOT FOR ELDERLY
Document Type and Number:
WIPO Patent Application WO/2021/017048
Kind Code:
A1
Abstract:
An obstacle-crossing accompanying robot for the elderly, the robot comprising a chassis (1), wheel frames being symmetrically mounted at two ends of the chassis; three first crawler wheels (5), four second crawler wheels (6), two third crawler wheels (8) and crawlers are respectively mounted on the wheel frames; a front steering engine (10) is mounted at the front end of the upper surface of the chassis; a front obstacle-crossing wheel (14) is mounted on the front steering engine by means of two front obstacle-crossing wheel connecting rods and a front wheel shaft; a motor box (16) is mounted at the rear end of the upper surface of the chassis; output shafts of two motors in the motor box are respectively connected to wheel shafts of the first crawler wheels at the tops of triangular connecting frames of the two wheel frames by means of shaft couplers; a tray (22) is mounted at the upper surface of the chassis by means of an electric telescopic rod (21); a rear steering engine (17) is mounted at the rear end of the chassis; and the rear steering engine is connected by means of two rear obstacle-crossing wheel connecting rods, and a rear obstacle-crossing wheels (20) are mounted on a rear wheel shaft. Compared to a common wheel-type or crawler-type mechanism, the obstacle-crossing structure combining the front and rear obstacle-crossing wheel connecting rods with the rear obstacle-crossing wheels may be used to achieve obstacle-crossing on condition that the tray is inclined, so as to help the elderly carry goods.
