Small unmanned aerial vehicle can open and close the hatch load lifting mechanism

Abstract

The invention discloses an openable-closeable cabin door unmanned aerial vehicle load lifting mechanism. Ascending and descending of a platform and vertical limiting of a pod mounting plate are realized through two ball screws, vertical movement of the platform and horizontal limiting of the pod mounting plate are realized through two carbon tubes. A motor drives the ball screws to run, a synchronous wheel ensures the ball screws to move synchronously, the ball screws drive a middle mounting plate to lift and lower a task load, a servo motor controls opening and closing of a cabin door through a signal processing system, a Hall sensor and a magnetic block control a lifting mechanism to stop moving, and a lock fastener and a lock block ensure stability of the platform after working and being recycled. The task load is connected with the middle mounting plate and can be replaced at any time. By using the mechanism, closing load of the cabin door is unaffected in the process of launching and recycling an unmanned aerial vehicle, and pneumatic performance of the unmanned aerial vehicle can be ensured. The load can be replaced and mounted at any time before the unmanned aerial vehicle takes off, the mechanism is convenient, quick, small in occupied space, light in weight and economically feasible, and overall performance, safety and reliability of the unmanned aerial vehicle are improved greatly.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle load task system, which is especially suitable for the load of micro-miniature unmanned aerial vehicles, which can carry out lifting operation on the task load and realize the opening and closing of the cabin door. Background technique [0002] At present, most of my country's UAVs are micro-miniature UAVs, which can carry small loads and narrow available space. The openings for ordinary loads often have a huge impact on aerodynamic performance. Therefore, it is urgent to design a load lifting mechanism that can install ordinary loads in a narrow load compartment, realize the opening and closing of the hatch to reduce the aerodynamic impact, and at the same time ensure the load weight requirements of the UAV. But, there is no openable and closable hatch door load lifting mechanism invented for the above-mentioned difficult problem in the industry at present. Contents of the invention [0003] The o...
