The invention relates to a security unmanned aerial vehicle with undercarriage folding and unfolding functions and a high-definition shooting function. The unmanned aerial vehicle comprises a main body, a camera, four flight devices and four brackets, and further comprises a folding and unfolding mechanism and four supporting mechanisms, the folding and unfolding mechanism comprises a first cylindrical notch, a piston block, a first permanent magnet, a second permanent magnet, an air pressure sensor, a connecting rod and four air collecting assemblies, each supporting mechanism comprises a second cylindrical notch, an undercarriage, a buffer assembly, a spring, a third pipeline, a second electric valve, a second pipeline and a first electric valve, each air collecting assembly comprises anair collecting pipe, a third electric valve and a first pipeline, and each buffer assembly comprises an air conveying hole and an air bag. The buffering effect on the camera is achieved through the folding and unfolding mechanism, shaking of the camera is reduced, the shooting definition of the unmanned aerial vehicle is improved, shielding of the supporting mechanisms on shooting of the camera is reduced through folding and unfolding of the supporting mechanisms, and the practicability of the unmanned aerial vehicle is improved.

    本发明涉及一种拍摄清晰的具有起落架收放功能的安防无人机,包括主体、摄像头、四个飞行装置和四个支架,还包括收放机构和四个支撑机构,收放机构包括第一柱形凹口、活塞块、第一永磁铁、第二永磁铁、气压传感器、连接杆和四个集气组件,支撑机构包括第二柱形凹口、起落架、缓冲组件、弹簧、第三管道、第二电动阀、第二管道和第一电动阀,集气组件包括集气管、第三电动阀和第一管道,缓冲组件包括输气孔和气囊,该拍摄清晰的具有起落架收放功能的安防无人机中,通过收放机构实现了对摄像头的缓冲作用,减小了摄像头的抖动,提高了无人机拍摄的清晰度,通过支撑机构的收放,降低了支撑机构对摄像头拍摄的遮挡,提高了无人机的实用性。
