AGV chassis structure capable of adapting to ground deformation

Abstract

The invention provides an AGV chassis structure capable of adapting to ground deformation. The AGV chassis structure comprises a bearing vehicle frame, a first movable vehicle frame, a second movable vehicle frame, a drive device and bearing wheels. The inner end of the first movable vehicle frame and the inner end of the second movable vehicle frame are hinged through a hinging shaft. The drive device comprises drive motors, drive shafts and drive wheels, wherein the drive shafts are coaxially connected with the hinging shaft, and the drive motors drive the drive wheels through the drive shafts. A first hinging hole is formed in the first movable vehicle frame, a second hinging hole is formed in the second movable vehicle frame, the bearing vehicle frame is hinged to the first hinging hole through a first connecting pin and hinged to the second hinging hole through a second connecting pin, and the second hinging hole is a kidney-shaped hole. When the first movable vehicle frame and the second movable vehicle frame relatively rotate around the hinging shaft, the first connecting pin moves relative to the first hinging hole, and the second connecting pin moves relative to the second hinging hole. When the AGV chassis structure encounters the uneven ground, the first movable vehicle frame and the second movable vehicle frame rotate relatively, it is guaranteed that the drive wheels are landed, and the uneven ground is adjusted.

Description

technical field [0001] The invention belongs to the technical field of AGV chassis structure, in particular to an AGV chassis structure that can adapt to ground deformation. 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 of traditional AGV vehicles, especially small AGV vehicles, is often limited by the size of the space, and the chassis does not have a suspension system. When the AGV vehicle is used on uneven ground, the chassis shakes greatly and the driving wheels appear suspended, resulting in The AGV cannot drive normally and cannot ensure the safety of the cargo. In order to prevent the driving wheel from being suspended, the chassis of the AGV is generally equipped with elastic parts, but the chassis with elastic parts has a complicated structure and high manufacturing cost, which cannot meet ...

Problems solved by technology

The chassis of traditional AGV vehicles, especially small AGV vehicles, is often limited by the size of the space, and the chassis does not have a suspension system. When the AGV vehicle is used on uneven ground, the chassis shakes greatly and the driving wheels appear suspended, resulting in The AGV cannot drive normally and cannot ensure the safety of the cargo

In order to prevent the driving wheel from hanging in the air, the chassis of the AGV car is generally equipped with elastic parts, but the chassis with elastic parts has a complex structure and high manufacturing cost, which cannot meet people's needs.
