Description

Unmanned aerial vehicle horn locking device, horn and unmanned aerial vehicle Technical Field Relates to the technical field of locking parts, in particular to locking of an unmanned aerial vehicle arm. Background In the current society, with the application of unmanned aerial vehicles in various fields of various industries, people also recognize more and more unmanned aerial vehicles. From the perspective of the whole appearance, the multi-rotor plant protection unmanned aerial vehicle mainly comprises a machine body, a horn, a rotor, a foot rest and other parts, and meanwhile, modules with various functions, such as a precision direct seeding device, a broadcasting device, a pesticide spraying device, a fertilizer application device and the like, are mounted below the machine body to meet the requirements of agricultural aviation on various sowing, fertilizing, pesticide spraying and the like. At present, in the field of agricultural aviation, the larger the load quantity or the load capacity is, the more favored the users are, the load capacity is increased, and the improvement of unit operation efficiency of agriculture is facilitated. And the load capacity is improved, so that the requirements of all parts of the unmanned aerial vehicle are obviously improved correspondingly. If the horn grows, the battery capacity promotes, the power of rotor motor increases, the rotor size grow, at this moment, just whole unmanned aerial vehicle becomes big in the space, faces current general unmanned aerial vehicle of 40-50KG, after the volume grow, produces inconveniently in packing, transportation, control, conventional operations such as transport. The folding horn mechanism is generally adopted in the industry to realize the folding of the horn, so that the size of the whole machine can be correspondingly reduced after folding, in the prior art, a user usually only unfolds the horn of the unmanned aerial vehicle before using the unmanned aerial vehicle, and hardly notices whether the horn is unfolded in place or not and whether the horn is locked after being unfolded, however, when the horn is not unfolded in place or the horn is unlocked after being unfolded, the propeller is started, vibration of the horn is easily caused, the horn is loosened, even the unmanned aerial vehicle is abnormally dropped, the unmanned aerial vehicle is damaged, and the use safety of the unmanned aerial vehicle is greatly reduced. The utility model patent with the publication number 202120352005.6 and 7 of 2021 is provided by Dongguan unmanned aerial vehicle technology limited company, and comprises a locking structure capable of locking a horn in a state of being unfolded, wherein the locking structure comprises a first locking piece and a second locking piece which can mutually wrap the first locking piece in a ring shape, the first locking piece comprises a push rod facing to the fixed end of the first locking piece, the push rod is pushed towards the connecting part of the first locking piece and the horn in a buckling state, and a stress structure is arranged at the end part of the second locking piece, and the push rod can fully push the end part of the second locking piece to the limit towards the fixed end of the first locking piece through the stress structure in a state of fully buckling the second locking piece so as to ensure the full wrapping of the first locking piece and the second locking piece; However, since the first locking piece and the second locking piece thereof need to be independently operated, the steps are complicated in the operation of actually expanding and folding the horn, and since the horn needs to be manually expanded before locking, the horn with high overall weight can cause burden to the operator, the complicated operation and the burden of weight, resulting in the problem that the locking structure is inconvenient to operate. The utility model patent with the publication number 202022577797.5, which is published on day 2021, 11, 9 and is provided by Dajiang Innovative technology Inc. in Shenzhen, comprises an unmanned aerial vehicle folding arm body which can be switched between an unfolding position and a folding position, wherein the arm body comprises a first body and a second body, the locking is completed by adopting a first locking piece and a second locking piece which are mutually matched, and from the view of combining pictures and characters, the locking mode is that the first locking piece and the second locking piece are matched and restrained through the inclined pulling structure, when the first locking piece is buckled, one end, connected with the second locking piece, of the inclined pulling structure is pushed to move towards the fixed end of the first locking piece, and when the second locking piece moves towards the fixed end of the first locking piece under the action of pushing force, negative angle counteraction is generated between the second locking piece and the inclin
