The invention discloses an improved air-land dual-purpose four-rotor unmanned aerial vehicle which comprises a vehicle body, two front vehicle arms arranged on the two sides of the front portion of the vehicle body, two rear vehicle arms arranged on the two sides of the rear portion of the vehicle body respectively, two front rotors arranged on the front vehicle arms respectively and two rear rotors arranged on the rear vehicle arms respectively, two front wheel spherical protective covers which respectively sleeve the two front rotors and are rotationally connected with the front arms, and two rear wheel spherical protective covers which respectively sleeve the two rear rotors and are rotationally connected with the rear arms; the front wheel spherical protective cover and the rear wheel spherical protective cover are hollow, and the diameter of the front wheel spherical protective cover is smaller than that of the rear wheel spherical protective cover. According to the improved air-land dual-purpose four-rotor unmanned aerial vehicle, air navigation and land walking can be achieved through one set of power system, the rotors can be protected to a certain degree, the rotors are not prone to colliding with foreign objects and accidentally hurting others, the trafficability can be enhanced through the improvement of the chassis, the overall structure is ingenious and simple, the mass is reduced, the flexibility is enhanced, and large-scale application and popularization are facilitated.
本发明公开一种改进型空陆两用四旋翼无人机,其中,包括机身、设在机身前部两侧的两根前机臂,分设在机身后部两侧的两根后机臂,分设在前机臂的两个前旋翼,分设在后机臂的两个后旋翼,分别套设在两个前旋翼并与前机臂转动连接的两个前轮球形防护罩以及分别套设在两个后旋翼并与后机臂转动连接的两个后轮球形防护罩,前轮球形防护罩和后轮球形防护罩均为镂空设计并且前轮球形防护罩的直径小于后轮球形防护罩的直径。本案采用一套动力系统就能实现空中航行和陆地行走,并可对旋翼起到一定保护作用,不易碰撞外物和意外伤害他人,而且底盘的提高可增强通过性,整体结构巧妙简洁,质量降低,灵活性增强,利于大量推广使用。
