Description
Technical field
The utility model belongs to technical field of aerospace, is specifically related to a kind of many rotor unmanned aircrafts and folding and self-locking apparatus thereof.
Background technology
Existing small-sized many rotor unmanned aircrafts propeller bracket connection structure, be divided into fixing and collapsible two kinds, fixing connection structure has volume larger, carry and load inconvenient defect, and current applied fold mechanism utilizes C type to buckle to realize, the characteristic that C type is buckled is that propeller bracket and frame are rotating state when screw propeller does not have lift, when screw propeller has lift, propeller bracket could be relative with frame fixing, greatly reduce stability and the fastness of aircraft, increase the degree of wear of propeller bracket and frame, the utility model makes two kinds of stationary states firm by a kind of stop gear of design, improve fold mechanism wearing and tearing, improve stability and the fold mechanism fastness of aircraft.
Summary of the invention
The purpose of this utility model is to provide the unmanned folding and self-locking apparatus of a kind of many rotors, improves the stability of small-sized many rotors fold mechanism, fastness and durability by rotatable positioning member and the locked fixing mode of elasticity locking device.
The technical solution of the utility model is: a kind of many rotor unmanned aircrafts folding and self-locking apparatus, this folding and self-locking apparatus is arranged at the junction of aircraft center main frame and overhanging rotor support, the second assembly that described folding and self-locking apparatus is comprised the first assembly and is attached thereto by bearing pin; Described first assembly comprises the side plate be parallel to each other for a pair and the elasticity locking device be arranged between described side plate; Described second assembly comprises rotatable positioning member and the support jointing be fixedly connected with it; Described rotatable positioning member has at least two grooves, realizes locked fixing for coordinating with described elasticity locking device.
The utility model provides a kind of many rotor unmanned aircrafts simultaneously, and comprise the mainframe and multiple overhanging rotor support that are positioned at aircraft center, this aircraft adopts folding and self-locking apparatus as above.
Technique effect of the present utility model is: the utility model is small-sized many rotor unmanned aircrafts folding and self-locking structure, when aircraft is in end state of flight, can by folding downwards for propeller bracket so that actv. saves space, and be no matter that propeller bracket is in level or vertical, elasticity locking device and rotatable positioning member groove part are in locking state, owing to being in locking state, decrease the wearing and tearing of support and frame, for former each class formation, this structure is more stable, more firm, more durable.

Detailed description of the invention
Below in conjunction with accompanying drawing 1-3, detailed description of the invention of the present utility model is described.
Folding and self-locking apparatus of the present utility model is arranged at the junction of aircraft center main frame 11 and overhanging rotor support 12, the second assembly comprising the first assembly and be attached thereto by bearing pin; Described first assembly comprises the side plate 1 be parallel to each other for a pair and the elasticity locking device be arranged between described side plate 1; Described elasticity is locked be installed on comprise be arranged at strut bar 2 between described side plate 1, sliding bar 5 that one end crosses described strut bar 2 slidably, the locked pin 4 be fixedly connected with sliding bar 5 other end, between strut bar 2 and locked pin 4 and the spring 3 be set on sliding bar 5; Side plate 1 has chute 6, for setting up locked pin 4.Described second assembly comprises rotatable positioning member 7 and the support jointing 8 be fixedly connected with it; The angle that described rotatable positioning member 7 has between two grooves, 9, two grooves 9 is 90 °, realizes locked fixing for coordinating with described elasticity locking device.Described locked pin 4 can slide in the chute 6 of described pair of side plates 1, by external force, locked pin 4 is compressed with spring 3, now the second assembly is in loosening state, can selection level or vertical groove, decontroling locked pin 4 with spring 3 combines with groove 9, be in self-locking state, locked pin 4 is stuck with groove 9, and rotor support 12 and mainframe 11 just can be fixed relative to one another.
In the present embodiment, rotor support 12 is tubular structure, and corresponding support jointing 8 is pipe clamp.
In order to expendable weight, described side plate 1 adopts engraved structure to design.
When aircraft is in preparation flight or state of flight, rotor support 12 is in level, when aircraft terminates flight, rotor support 12 can be regained and be in vertically.
The above embodiment is only preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
