Front wheel steering chassis of security robot

Abstract

The invention discloses a front wheel steering chassis of a security robot. By adopting the steering chassis of a structure, during steering, all wheels make pure rolling, steering force is reduced, and thus motor power is reduced; and a damping mechanism is arranged, so that during obstacle crossing of the robot, a vehicle body is stable, and vibration is small. The front wheel steering chassis comprises a vehicle frame, a front wheel assembly, a rear wheel assembly and a steering mechanism. The front wheel assembly and the rear wheel assembly are supported at the front end and the rear end of the vehicle frame correspondingly, and the steering mechanism is mounted on the lower surface of the vehicle frame. Position arrangement of the front and rear wheels and a steering gear in the frontwheel steering chassis conforms to the Ackerman angle theory, it can be guaranteed that during steering, all the wheels make pure rolling, the steering force is reduced, and thus the motor power is reduced.

Description

technical field [0001] The invention relates to a steering chassis, in particular to a front wheel steering chassis, and belongs to the technical field of security robots. technical background [0002] The security robot is equipped with electrical components such as cameras and sensors, and can replace security personnel such as security guards and police officers to patrol the park. In order for the various electrical appliances on the security robot to function better, the chassis structure of the security robot needs to be stable and safe. The existing security robot chassis is a differential steering chassis. The four wheels of the differential steering chassis are controlled by the drive motor. The difference achieves steering. The steering force required for differential steering is very large, so a high-power motor is required, which increases the cost. And there is no shock-absorbing system, so that when the robot crosses obstacles, there will be large bumps, and...

Problems solved by technology

The steering force required for differential steering is very large, so a high-power motor is required, which increases the cost

And there is no shock absorption system, which makes the robot bump more when it crosses obstacles, and the vibration of the electric control is larger, making it easy to loosen and poor contact. In addition, the image transmitted by the camera is not stable
