UAV airborne equipment vertical retractable mechanism and UAV

Abstract

The invention provides a vertical retractable mechanism for on-board equipment of a UAV and a UAV, including a mounting frame, an equipment carrying frame and at least two screw drive pairs, and the equipment carrying frame is provided with a connected first limiting hole and the second limit hole; the screw drive pair includes a screw main body and a drive nut, the drive nut is screwed outside the screw main body, the screw main body is rotatably connected to the mounting bracket, the screw main body passes through the first limit hole, and the screw There is a gap between the outer peripheral surface of the rod main body and the hole wall of the first limiting hole; the transmission nut is inserted into the second limiting hole, and there is a gap between the outer peripheral surface of the driving nut and the hole wall of the second limiting hole. The drive nut is connected with the circumferential limit of the hole wall of the second limit hole. Through the improvement of the screw drive pair, adaptive adjustments can be made during the assembly process to ensure the coaxiality of the screw main body and the drive nut, and to adjust multiple nuts on the same level to avoid the occurrence of problems during the relative operation of the screw main body and the drive nut. Stuck situation.

Description

technical field [0001] The present invention relates to the field of aircraft, in particular to a vertical retractable mechanism for on-board equipment of an unmanned aerial vehicle and an unmanned aerial vehicle. Background technique [0002] When most UAVs perform tasks, the mission equipment they carry needs to be deployed outside the body for work; while in the non-mission phase, it needs to be retracted into the body to protect the equipment and reduce flight resistance. Therefore, it is necessary to design retractable mechanisms for these airborne devices to meet their application requirements. [0003] At present, the more common retractable mechanisms include rotary retractable mechanisms and vertical retractable mechanisms. [0004] The inventor found in the research that the retractable mechanism of the traditional UAV airborne equipment has at least the following disadvantages: [0005] First, the rotary retractable mechanism requires a large space in the horizo...
