The invention relates to the technical field of unmanned aerial vehicles, and discloses an electromagnetic brake system for an unmanned aerial vehicle, and the unmanned aerial vehicle. The system comprises a magnetic device, a dynamic friction plate, a static friction plate and an elastic reed, the elastic reed is connected with a hub, the dynamic friction plate is connected with the elastic reed,the static friction plate is connected with the magnetic device, the magnetic device is connected with an undercarriage supporting column of the unmanned aerial vehicle, and when the unmanned aerialvehicle slides normally, the dynamic friction plate, the elastic reed and the hub rotate along with a wheel, and a preset gap is formed between the dynamic friction plate and the static friction plateand when the unmanned aerial vehicle is braked, an external power supply supplies power to the electromagnetic device, the electromagnetic device generates magnetism after being powered on and generates attraction to the movable friction plate, so that the movable friction plate and the static friction plate are tightly attached together to generate sliding friction force, and then deceleration braking of the unmanned aerial vehicle is achieved. The system has the following advantages: the braking force is steplessly adjustable, and the maintenance difficulty is low.

    本发明涉及无人机技术领域,公开了一种无人机用电磁刹车系统及无人机。其中,该系统包括磁性装置、动摩擦片、静摩擦片和弹性簧片,所述弹性簧片与轮毂连接,所述动摩擦片与所述弹性簧片连接、所述静摩擦片与所述磁性装置连接,所述磁性装置与无人机的起落架支柱连接,所述无人机正常滑跑时,所述动摩擦片、所述弹性簧片和所述轮毂随机轮一同旋转,且所述动摩擦片与所述静摩擦片之间具有预定间隙;所述无人机刹车时,通过外部电源为所述电磁装置供电,所述电磁装置通电后产生磁性,对动摩擦片产生吸引力,使得所述动摩擦片与所述静摩擦片紧密贴附在一起产生滑动摩擦力,进而实现无人机的减速刹车。该系统具有刹车力无级可调且维护难度小的优点。
