A universal wire-controlled chassis of an unmanned vehicle

Abstract

The invention provides a universal wire-controlled chassis for an unmanned vehicle, which adopts wire-controlled driving, braking and steering, and integrates mechanical and electronic control packaging of the chassis, has a plug-and-play function, and has the characteristics of generalization and platform. The universal wire-controlled includes a frame, a drive system mounted on the frame, a steering system and an electrical circuit system, a body enclosed on the frame, and wheels connected to the body through a suspension system. The servo motor provides driving torque and braking torque tothe wheels as driving wheels, and the parking brake is realized by the brake lock inside the servo motor. The steering system provides steering torque to the wheels as steering wheels by an electric motor. The circuit system includes a power supply and a vehicle controller. The power supply supplies power to the vehicle controller and the motors in the drive system and steering system; The whole vehicle controller is used for receiving the driving instruction, the braking instruction and the steering instruction of the upper computer.

Description

technical field [0001] The invention relates to an automobile chassis, in particular to a universal chassis for unmanned vehicles, which belongs to the field of vehicle chassis design. Background technique [0002] At present, labor costs continue to rise, and the demand for various small unmanned vehicles in the market is increasing day by day. There are more and more commercial unmanned vehicle landing projects in various fixed scenarios such as factories, residential areas, and campuses. However, at present, such unmanned vehicle companies can only choose traditional wheeled robots as their carrier chassis. This type of chassis is often not universally designed for the above-mentioned scenarios, and the ride comfort and mobility are difficult to meet the standards of the vehicle, and it does not have enough driving range to meet the needs of small unmanned vehicles. [0003] However, most of the common security vehicles and sweeping vehicles on the market are designed fo...

AI Technical Summary

Problems solved by technology

However, at present, such unmanned vehicle companies can only choose traditional wheeled robots as their carrier chassis.

This type of chassis is often not universally designed for the above-mentioned scenarios, and the ride comfort and mobility are difficult to meet the vehicle standards, nor does it have sufficient driving range, and it is difficult to meet the needs of small unmanned vehicles.

[0003] However, most of the common security vehicles and sweeping vehicles on the market are designed for manned driving. Except for the drive system, the steering, suspension and other systems are completely mechanically connected. The perception system of people and vehicles is powered, and it is unable to receive instructions from the decision-making system
