Ground self-adaptive AGV chassis and AGV

Abstract

The invention discloses a ground self-adaptive AGV chassis and an AGV, and relates to the technical field of intelligent carrying. The ground self-adaptive AGV chassis comprises a chassis body, a rotating plate, at least two wheel sets and an elastic pressure mechanism. The rotating plate is rotatably connected with the front end of the chassis body through a fulcrum rotating shaft and located below the chassis body, and a gap is formed between the rotating plate and the chassis body. Each wheel set comprises two walking wheels, at least one walking wheel is a driving wheel, one wheel set serves as a front wheel set to be installed on the rotating plate, and the remaining wheel set is installed on the chassis body. The two ends of the elastic pressure mechanism are hinged to the chassis body and the rotating plate correspondingly. The elastic pressure mechanism is used for applying pressure to the rotating plate so that the front wheel set can be attached to the ground, and the compression amount of the elastic pressure mechanism can be adjusted through the rotating plate. By introducing the elastic pressure mechanism to be combined with the rotating plate, reliable pressure contact between the front wheel set and the ground is achieved, the shaking amplitude of the ground self-adaptive AGV chassis adapting to the ground is minimized, a wheel train is automatically adjusted, and shaking is reduced.

Problems solved by technology

[0002] AGV is the abbreviation of Automated Guided Vehicle, that is, automatic guided transport vehicles, which are widely used in logistics, automation operations and other fields, such as AGV cars, storage robots, autonomous inspections, industrial automation robots, etc. The chassis is the main part of the hardware that constitutes the AGV. The wheel train and support frame, the excellent performance of AGV depends largely on the design of the basic chassis. In traditional AGV vehicles, the chassis of small AGV vehicles is often limited by the space size, and the chassis does not have a suspension system. When used on uneven ground, the chassis shakes greatly and the driving wheels hang in the air, resulting in insufficient grip of the AGV driving wheels, slipping wheels, and unable to drive normally. In order to improve the suspension phenomenon of the drive wheel and reduce the shaking amplitude, some technologies have installed elastic parts in the chassis of the AGV. This method solves the suspension and shaking problems to a certain extent, and can be applied to relatively flat ground conditions and low positioning accuracy. However, with the expansion of the application field of AGV technology, such as building decoration, off-site construction, etc., the existing technology cannot well solve the problem of good wheel grip, strong adaptability to the ground, and heavy loads. Therefore, it is necessary to Design an AGV chassis with excellent ground self-adaption to solve engineering application problems encountered
