Quick-release horizontal tail connecting device for unmanned aerial vehicle

Abstract

The invention discloses a quick-release horizontal tail connecting device for an unmanned aerial vehicle, and belongs to the technical field of unmanned aerial vehicles. The quick-release horizontal tail connecting device for the unmanned aerial vehicle comprises a main machine tail, a worm is rotationally connected into a cavity, and the left side and the right side of the cylindrical end of the worm penetrate through the inner wall of the cavity, extend to the outer portion of a fixing block and are coaxially connected with lead screws. A crank is arranged at the middle part of the left side of the lower portion of the fixing block. The upper end of the crank sequentially penetrates through the outer wall of the fixing block, extends into the cavity and is sleeved with a worm wheel, side horizontal tails are welded to the outer walls of the left side and the right side of the fixing block, two trapezoidal guide grooves are symmetrically formed in the inner walls of the side horizontal tails, contraction horizontal tails are arranged in the side horizontal tails, and penetrating threaded holes are formed in the middles in the contraction horizontal tails. Through close fitting between the structures, The quick-release horizontal tail connecting device is convenient to disassemble and assemble, the horizontal tails can be stored in the disassembly process, the horizontal tails on the two sides can form a whole, the quick-release block is more stable, the trouble of two-time installation is avoided, and the purpose of quick-release block installation is effectively improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, and more specifically, relates to a quick-release flat-tail connection device for unmanned aerial vehicles. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. Drones are often better suited for missions that are too "dumb, dirty or dangerous" than manned aircraft. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid needs of drones; currently, they are used in aerial photography, agriculture, plant protection, micro selfies, expres...

Problems solved by technology

[0003] The prior art publication number is CN111806670A, which provides a quick-release flat tail connection device for unmanned aerial vehicles. The inventor found the following problems while realizing the prior art: 1. The device passes through the chute and a plurality of Screw installation, the structure is too simple, and the flat tail cannot be stored after disassembly, and the actual work effect is not good; 2. The device cannot adjust the length of the flat tail according to the actual situation, but it is the same as the traditional method of directly fixing by multiple bolts. The disassembly process 3. The device cannot realize quick disassembly and quick assembly during installation and disassembly, which reduces the work efficiency of the corresponding work, and the actual work effect is not good. In view of this, we propose a UAV quick release and flat tail connection device
