The invention belongs to the technical field of unmanned trolleys, and relates to an obstacle avoidance structure and an unmanned trolley with the same. The obstacle avoidance structure comprises a chassis, a first bevel gear and a rotating plate. A through hole is formed in the middle of the chassis, and a connecting plate is arranged above the chassis in an up-down moving mode. The middle of the rotating plate is rotationally connected with the bottom of the chassis through a fixing shaft. A second bevel gear is rotationally mounted at one end of the rotating plate, and a mounting seat is rotationally mounted at the other end of the rotating plate and provided with a driving wheel. When the unmanned trolley needs to turn, the first bevel gear and the mounting seat are rotated, so that the orientation of the driving wheel is changed, and the purpose of turning is achieved. When the unmanned trolley needs to turn or turn round in a narrow space, a connecting plate moves downwards, a first bevel gear moves downwards, a rotating plate rotates around a fixed shaft, the end, provided with a driving wheel, of the rotating plate rotates in the direction close to a first rotating shaft, and then the turning radius of the unmanned trolley becomes smaller; therefore, the unmanned trolley can turn or turn around in a narrow space.
本发明属于无人小车技术领域,涉及一种避障结构及具其的无人小车。避障结构包括底盘、第一锥齿轮和转动板。底盘的中间开设有通孔,底盘的上方上下移动设置有连接板。转动板的中部与底盘的底部通过固定轴转动连接。转动板的一端转动安装有第二锥齿轮,转动板的另一端转动安装有安装座,安装座安装有驱动轮。无人小车需要转弯时,使第一锥齿轮转动,安装座转动,进而改变驱动轮的朝向,达到转向的目的。当无人小车需要在狭窄的空间转弯或掉头时,使连接板向下运动,第一锥齿轮向下运动,转动板绕着固定轴转动,转动板安装有驱动轮的一端向靠近第一转轴的方向转动,进而使无人小车的转弯半径变小,使无人小车可以在狭窄的空间转弯或掉头。
