specific Embodiment approach 1
[0023] Specific implementation mode 1. Combination Figure 1 to Figure 5 Description of this embodiment, a UAV pod retractable mechanism is mainly composed of four parts: a fixed assembly, a rotating assembly, a slider crank mechanism, and an auxiliary locking mechanism. The fixed plate lug 17 of the hinged fixed assembly and the moving plate lug 4 of the rotating assembly make the fixed assembly and the rotating assembly connected as a rotating pair; the slider crank mechanism drives the rotating assembly to rotate through the crank 9; the auxiliary locking mechanism changes the rotating assembly During the rotation process, the hanging point position of the locking tension spring 6 realizes the reversing of the locking torque, and locks the rotating assembly to the fixed assembly in the state of lowering and retracting.
[0024] The fixed assembly is composed of a frame 5 and a fixed plate lug 17 . The frame 5 is used to install and fix the whole mechanism on the drone body...
specific Embodiment approach 2
[0027] Embodiment 2. This embodiment is an assembly process of a UAV pod retractable mechanism described in Embodiment 1: it is realized by the following steps:
[0028] Step 1: Fix the lifting lug 4 of the moving plate, the crank 9 and the sliding rail 8 of the moving hanging point on the vibration isolation plate 2 .
[0029] Step 2: Fix the pod 1 on the vibration isolation plate through the shock absorber 3 .
[0030] Step 3: Fix the fixed hanging point 7, the screw support 11, the motor base 13, the lower limit block 16, and the fixed plate lug 17 on the frame 5.
[0031] Step 4: Install the motor 14 on the motor base 13 .
[0032] Step five, put the slider 15 on the screw rod 12, connect one end of the screw rod 12 with the motor 14, and support the other end with the screw rod support 11.
[0033] Step 6: Hinge the lifting lug 17 of the fixed plate with the lifting lug 4 of the moving plate.
[0034] Step seven, connect the slider 15 and the crank 9 with the connectin...

Abstract
The invention discloses an unmanned aerial vehicle nacelle retracting mechanism and an assembly method and relates to the technical field of unmanned aerial vehicle nacelle retracting. The problems of reliable retracting and releasing of an unmanned aerial vehicle nacelle and the stability of a nacelle body in a working state are solved. The unmanned aerial vehicle nacelle retracting mechanism is mainly composed of a fixed assembly, a rotating assembly, a slide block crank mechanism and an auxiliary locking mechanism. The nacelle is fixed to a vibration isolation plate through a vibration absorber, so that the rotating assembly is composed. The fixed assembly is in pin shaft connection with the rotating assembly. A slide block of the slide block crank mechanism pushes a crank and the rotating assembly to rotate through a connection rod. Reversing of the locking torque of the auxiliary locking mechanism is achieved by changing the hanging point position of a locking tension spring in the rotating process of the rotating assembly, the rotating assembly is locked to the fixed assembly under the releasing and retracting states, and the stabilization of the nacelle body is achieved. According to the unmanned aerial vehicle nacelle retracting mechanism and the assembly method, the structure is compact, retracting, releasing and supporting of the nacelle are achieved in a modularized mode, and the nacelle is pushed to be rotationally retracted and released through the slide block crank mechanism subjected to size optimization; and the driving force requirement for a power source is reduced as far as possible, and the driving mechanism size is decreased.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicle pod retraction, in particular to an unmanned aerial vehicle pod retraction mechanism. Background technique [0002] At present, UAVs are not limited to the military field, but have gradually expanded to the civilian field. The main role of UAVs is to carry pods on UAVs and complete predetermined tasks. Due to various working conditions during the flight of the UAV, it is necessary to properly stow the pod when it is not working to protect the pod and reduce the flight resistance of the aircraft. U.S. Patent 4635067 proposes an airborne radar retractable mechanism, which reliably realizes the parallel retractable and lowered radar, but the mechanism is complex and large in size, and cannot be suitable for retractable UAV pods with limited installation space; China Patent 201420563246.5 proposes a UAV pod. This device mainly realizes the exposure and retraction of the pod by opening...
