The invention provides a self-service obstacle crossing wheel for a sweeper, and relates to the related field of wheels, the self-service obstacle crossing wheel comprises wheel carriers symmetrically embedded in the two sides of a vehicle body, a shell is fixedly installed on one side of each wheel carrier, a driving shaft of the vehicle body extends to the inner side of each wheel carrier and is provided with a rear driving wheel, and the sweeper has the obstacle crossing ability through an obstacle crossing mechanism installed on a front wheel; after the obstacle crossing mechanism is unfolded, the structural strength after deformation can be effectively enhanced, the bottom rubbing prevention mechanism adopts a crawler belt as protection for preventing a chassis from being rubbed, the bottom rubbing prevention mechanism and a rear driving wheel adopt the same power, when the obstacle crossing mechanism crosses the obstacle, the crawler belt is used as a support between a vehicle body and a protruding obstacle to protect the chassis, and under the condition that the obstacle crossing mechanism crosses an abrupt slope or stairs, the chassis is protected. The position of the guide wheel can be automatically adjusted according to the gradient, on the premise that the chassis can be protected, the crawler belt makes contact with the ground later, it is guaranteed that the sweeper head can be located at the low position all the time, the view of a driver is guaranteed, and the probability of traffic accidents is reduced.

    本发明的一种扫地机用自助越障轮,涉及车轮相关领域,包括对称嵌设于车体两侧的轮架,所述轮架一侧固定安装有外壳,所述车体的驱动轴延伸至所述轮架内侧且安装有后驱动轮,通过安装在前轮上的越障机构使得扫地机具备越障能力,越障机构展开后能够有效增强变形后的结构强度,防蹭底机构采用履带作为防止底盘剐蹭的保护,且与后驱动轮采用同一动力,在越过障碍时,通过履带作为车体与凸起障碍之间的支撑,保护底盘,在越过陡坡或楼梯的情况下,能够根据坡度自动调节引导轮的位置,在能够保护底盘的前提下,履带较晚与地面接触,确保扫地机车头能够始终处于较低的位置,从而保证驾驶员的视野,降低交通事故发生的几率。
