Publication number: 20160368596Abstract: A fully protected drone includes a drone body and a rotary wing connected to the drone body, and further includes a protection housing connected to the drone body. The protection housing is a meshed closed housing and has a hollow cavity. The rotary wing is mounted in the hollow cavity. According to the present application, the rotary wing is mounted in the hollow cavity of the protection housing, the rotary wing will not contact the human body, thus an operator can fly or retrieve the drone by hand, which improves the operation convenience of the rotary wing, and improves the operation security to a large extent. The protection housing is configured as a meshed closed housing. The rotary wing is mounted in the protection housing connected to the drone body, thereby reducing the overall height of the drone and improving the portability of the drone.Type: ApplicationFiled: December 29, 2015Publication date: December 22, 2016Applicant: BEIJING ZERO ZERO INFINITY TECHNOLOGY CO., LTDInventors: Tong ZHANG, Mengqiu WANG, Zhaozhe WANG, Xuyang ZHANG, Guanqun ZHANG, Shuang GONG, Yalin ZHANG, Jinglong WANG, Lixin LIU
