Rotary locking mechanism for wings of barrel-shooting type unmanned aerial vehicle

Abstract

The invention discloses a rotary locking mechanism for wings of a barrel-shooting type unmanned aerial vehicle. The rotary locking mechanism comprises a base, a driving torsional spring, a locking pin, a locking pin compression spring, a shock-proof rubber pad, a rotating wing connector and a cover plate. The driving torsional spring is placed in a driving torsional spring mounting groove, the locking pin is arranged in a locking pin limiting hole, and the upper end of the locking pin is sleeved with the locking pin compression spring; a rotary wing connector is arranged on the upper surface of the base, a driving torsional spring mounting groove is formed in the side of the top end of the rotary wing connector, and a locking pin limiting hole is formed in the side of the top end of the rotary drum sleeve. Rapid unfolding of wings can be realized, accurate positioning and reliable locking are realized, in addition, the design is reasonable, the application is convenient and fast, and the shape is regular. According to the design concept of a single torsion spring, the thickness of the whole rotary locking mechanism is effectively reduced, the effective use space of the unmanned aerial vehicle is increased, the limiting locking mechanism is small in occupied space and firm in locking, and when the wings are completely unfolded, the locking pins are pressed into the locking pin limiting holes by the locking pin compression springs to lock the wings.

Description

technical field [0001] The invention relates to a locking structure of an unmanned aerial vehicle, in particular to a barrel-fired unmanned aerial vehicle wing rotation locking mechanism, which belongs to the technical field of unmanned aerial vehicles. Background technique [0002] The tube-launched UAV is folded by the folding mechanism, which effectively reduces the space size. It adopts the tube-launch launch method, which has the characteristics of low cost, high cost ratio, and small size. Moreover, the flexible mobility and regional adaptability of the tube-launched UAV have attracted a large number of domestic and foreign experts to conduct in-depth research on it. [0003] The wing folding mechanism usually includes two parts: a folding and unfolding mechanism and a limit locking mechanism. According to the driving mode, the wing folding and unfolding mechanism can be roughly divided into electric driving type and spring driving type. Electric drive type: The moto...

Problems solved by technology

[0005] The purpose of the present invention is to provide a barrel-fired UAV wing rotation locking mechanism to solve the problem that two torsion springs independently drive the two wings in the above-mentioned background technology, but the common problems are complex structure, inconvenient installation, and occupation of big space issues

The limit locking mechanism of the folding mechanism has a slider type, a block type, a ball pin type, etc., and usually has disadvantages such as large structure volume and unstable locking.
