Universal base plate for heavy-load two-wheel differential robot

Abstract

The invention relates to a universal base plate for a heavy-load two-wheel differential robot. The universal base plate comprises a bottom plate. A suspension driving device is mounted in the middle of the bottom plate. Multiple support wheel devices are arranged on the portion, on the periphery of the suspension driving device, of the bottom plate. The suspension driving device comprises a middle shell and two driving wheel frames correspondingly located on the two sides of the middle shell. A connecting rod is arranged between each of the two sides of each driving wheel frame and the middle shell, and a four-connecting-rod mechanism is formed. Connecting end heads are correspondingly mounted on the tops of the two driving wheel frames. An adjustable spring is arranged between each connecting end head and the middle shell. The upper end of each adjustable spring is hinged to the top of the middle shell, and the lower end of each adjustable spring is hinged to the corresponding connecting end head. Driving wheel shafts with driving wheels at the outer ends are correspondingly mounted at the bottoms of the two driving wheel frames, and motors are correspondingly mounted on the inner sides of the two driving wheel frames. The outer end of a motor shaft of each motor is in butt joint with the inner end of the corresponding driving wheel shaft. Each support wheel device comprises a support wheel frame fixedly connected with the bottom plate. Universal wheels are mounted at the bottom of each support wheel frame.

Description

technical field [0001] The invention belongs to the technical field of robots, in particular to a general chassis of a heavy-duty two-wheel differential robot. Background technique [0002] With the development of technology, intelligent robot technology has gradually matured. The application fields of intelligent robots are also becoming more and more extensive. They can be used not only in logistics systems as moving vehicles, but also in places such as restaurants as food delivery robots and guiding robots. Intelligent robots are usually equipped with a chassis device for driving, carrying, etc., and a navigation device can be installed on the chassis device to cooperate with ground rails and positioning marks to realize autonomous navigation and walking. [0003] Existing chassis devices usually use road wheels driven by motors to drive, and the motors generally use chains to connect and drive the road wheels. Due to excessive load-bearing, it is difficult to drive the...

AI Technical Summary

Problems solved by technology

[0006] The advantages and positive effects of the present invention are: the present invention provides a general chassis of a heavy-duty two-wheel differential robot with a simple and reasonable structural design. The wheel device and the independent suspension drive device realize the technical effect of separation of load and drive, that is, multiple support wheel devices are used for load, and the suspension drive device provides two-wheel differential drive, so that the suspension drive device will not carry The larger weight also solves the problem of inability to carry heavy loads brought about by the integrated structure of drive and load pointed out in the background technology, and realizes the design and development of a heavy-duty chassis structure
