AGV chassis structure

Abstract

The invention provides an AGV chassis structure which comprises a bottom plate, a first movable frame, a second movable frame, a driving device and bearing wheels. The driving device is provided witha driving wheel and drives the driving wheel to rotate through a driving shaft; the first movable frame is hinged to the front end of the bottom plate through a first hinge point, so that a first force arm extending to the outer side of the bottom plate and a second force arm extending to the inner side of the bottom plate are formed by the first movable frame; the second movable frame is hinged to the rear end of the bottom plate through a second hinge point, so that a third force arm extending towards the inner side of the bottom plate and a fourth force arm extending towards the outer sideof the bottom plate are formed by the second movable frame, the bearing wheels are respectively arranged on the first force arm and the fourth force arm, the end parts of the second force arm and thethird force arm are hinged through a third hinge point, and the driving device is arranged on the second force arm and located between the first hinge point and the third hinge point. According to theAGV chassis structure, the driving force of the driving wheel can be ensured, so that stability and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of AGV chassis, and mainly relates to an AGV chassis structure. Background technique [0002] Backpack AGV refers to the AGV vehicle that relies on the AGV body to carry the weight of the cargo. This type of AGV vehicle is mostly used in assembly, logistics and other fields. The chassis structure of the existing AGV car, especially the small AGV car, generally realizes the adaptive ground deformation of the AGV car through two frame hinges, but the current AGV chassis structure is to connect the output shaft of the output device with two The hinged shaft of the frame adopts the coaxial connection method, which allows the AGV to keep the wheels of the two frames on the ground when it encounters an uneven road surface, but there will be driving problems caused by the simultaneous swing of the two frames. The slipping problem caused by insufficient driving force of the wheel makes the AGV work unstable and red...
