Description
Technical field
The utility model belongs to air vehicle technique field, more particularly, to a kind of multi-rotor unmanned aerial vehicle antenna folding structure.
Background technique
The installation of more gyroplane data-link antennas needs to consider the working space of antenna, the connection side of antenna and body
The problems such as formula, the occlusion issue of aerial signal, the convenience of antenna installation, the reliability of aerial mounting structure.Antenna folding and unfolding knot
The data-link antenna installed on structure belongs to the critical component of multi-rotor unmanned aerial vehicle, aircraft and ground when being multi-rotor unmanned aerial vehicle flight
The main element of communication, when work, need antenna periphery to communicate with ground surface end not to be blocked, and have certain stability,
Safety.Therefore a kind of multi-rotor unmanned aerial vehicle antenna folding structure is designed, had to the practical usability for improving multi-rotor unmanned aerial vehicle
It is significant.
Currently, the mounting structure of the existing antenna of multi-rotor unmanned aerial vehicle is broadly divided into following several types, as bolt connecting type,
Fold and be bolted convolution, cluster.It is screw connected to refer to that antenna base and fuselage connected component are to be bolted,
The mode that convolution refers to that antenna base is connected by screw bolts with fuselage connected component structure is folded and is bolted to be pacified
Dress, while pedestal has folding and retraction structure, cluster is directly to bundle antenna and fuselage.
The mounting structure disadvantage of antenna mainly shows at present: 1, do not can avoid occlusion issue when antenna and ground communication,
Data-link antenna needs moment and earth station to keep communicating when in use, but conventional mounting mode is all inevasible will cause machine
Body blocks antenna, thus data outage is caused notably to cause to fall machine.2, folding and unfolding effect is poor, since more gyroplanes fly
When data-link antenna communicate and cannot block with ground surface end, thus antenna need to be placed in the least significant end of entire aircraft, if but antenna not
It can damage of automatic deploying and retracting when will cause aircraft landing to antenna.3, effectiveness in vibration suppression is poor, since the flight condition of aircraft compares
Complexity can cause the vibration fine crushing of fuselage, the installation side of traditional antenna there are many vibration source (vibration of such as motor, the disturbance of wind)
Formula cannot effectively reduce influence of the fuselage shaking to antenna.4, space occupancy rate is high, empty to reduce more rotor collections and transport
Between, for aircraft each section decision design at automatic contractive or fast disassembly type, some antenna mounting means in use cannot be square
Just dismounting or folding and unfolding will cause the probability damaged when antenna transport in this way and increase and influence the collection and transport of more gyroplanes
