折叠伸缩机构、螺旋桨保护装置及旋翼无人机
Abstract:
一种折叠伸缩机构，包括第一主体(4)和第二主体(5)，第一主体(4)具有第一连接部(2)，第二主体(5)可相对第一主体(4)转动，并具有第二连接部(3)；所述第一连接部(2)与第二连接部(3)以可移动的方式组装，并具有收缩状态与伸展状态；在所述收缩状态，所述第一连接部(2)与第二连接部(3)至少部分叠合，并限制所述第一主体(4)与第二主体(5)的相对转动；在所述伸展状态，所述第一连接部(2)与第二连接部(3)相远离，第二主体(5)可转动并折叠在所述第一主体(4)上；所述折叠伸缩机构能够折叠和伸缩，可以提高展开使用状态时连接部位的强度。
Abstract(English):

A foldable telescoping mechanism comprises a first body (4) and a second body (5). The first body (4) has a first connecting part (2). The second body (5) can rotate relative to the first body (4) andhas a second connecting part (3). The first connecting part (2) and the second connecting part (3) are assembled in a movable manner and have a telescoping state and an extending state. In the telescoping state, the first connecting part (2) and the second connecting part (3) are at least partially superposed, and relative rotation between the first body (4) and the second body (5) is restricted.In the extending state, the first connecting part (2) is far from the second connecting part (3). The second body (5) is rotatable and is folded on the first body (4). The foldable telescoping mechanism can be folded and telescope and can improve strength of a connecting part in an extended use state.
