Abstract

The invention discloses a transformable-crawler suspension bracket. The transformable-crawler suspension bracket comprises a middle linkage rack, two transformable crawler units and a transformation driving assembly, wherein the transformable crawler units are connected with the middle linkage rack, and are symmetrically arranged; a transformable crawler rack of each transformable crawler unit is a six-rod mechanism, and comprises a four-rod motion chain and at least four crawler wheels; the crawler wheels of each transformable crawler rack comprise a driving wheel and turning wheels; the crawler wheels are connected with rotating pairs of the corresponding four-rod motion chain, and rods of the rotating pairs; a crawler wraps the corresponding crawler wheels; a crawler driving assembly drives the driving wheels, and the crawlers are driven to rotate; the transformation driving assembly is connected with the transformable crawler racks of the transformable crawler units and drives the transformable crawler racks to be transformed, and the bottoms of the crawlers can always be kept horizontal. The invention further discloses a robot moving platform with the transformable-crawler suspension bracket. Because the transformable-crawler suspension bracket is arranged, the terrain adaptability and the passing capability of the robot are improved, and the moving stability of the robot is also improved.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a deformed crawler suspension and a robot mobile platform with the same. Background technique [0002] Tracked walking suspension is widely used in the field of mobile robots. It occupies an important position in rescue and disaster relief, detection and reconnaissance, industry, agriculture and military, and has good application prospects, especially in complex and difficult environments. The incomparable adaptability and passability of robots, crawler suspension is currently a hot research field. China University of Mining and Technology has developed a W-shaped crawler suspension for crawler mobile platforms (application number: CN201320552131.1). The front and rear crawler units are in the shape of a trapezoid, and the crawler running part assembly is W-shaped, with four slope-shaped track sections. , which is conducive to climbing over obstacles; the horizontal section at th...
