Description
Technical field
The utility model belongs to unmanned helicopter field, more particularly to a kind of rotor structure of unmanned helicopter.
Background technology
Rotor wing unmanned aerial vehicle, also referred to as unmanned helicopter, its construction is fairly simple, and price is also cheaper, even more important
It is that it does not need emission system at all, moreover it is possible to VTOL more can freely hover, and flexibility of flying is quite superb,
It can fly with various speed, with the air route of various flight profile, mission profiles.In general flight quality, it can also show that " two is small
One is high " important feature：Chatter is small, noise is small, and Reliability comparotive is high.Therefore, in the country of Helicopter Technology prosperity, nobody drives
Helicopter is sailed to begin to develop very early.For example, the Kaman company in the U.S. just once releases pilotless helicopter early in the fifties, and
And there are some models to put into the practice stage.
Unmanned helicopter is rotated and upgraded by paddle and flown, and in order not to same flight demand, paddle has a variety of
Type, some paddles are centering setting, and positive and negative can be used, paddle be upper below-center offset, can only one towards cloth
Use is set, currently, needing to use different folder wing seats using different paddles, is not easy to a kind of a variety of paddles of helicopter outfit,
To adapt to a variety of flight demands.
Utility model content
In order to overcome the deficiencies of the prior art and there are the problem of, the utility model provides a kind of rotor knot of unmanned helicopter
Structure is suitable for installing different paddles, adaptable.
The utility model is achieved through the following technical solutions：
A kind of rotor structure of unmanned helicopter, including rotating seat, rotating seat are equipped with cross bar, and the both ends of cross bar are equipped with
With the folder wing seat of cross bar rotation connection, the folder wing seat is equipped with clamping opening, accompanies paddle in clamping opening, be lined between paddle and clamping opening
Trimmer, folder wing seat are equipped with the retaining mechanism for locking paddle.
The trimmer is equipped with one or more, and trimmer is equipped with multi-thickness specification.
The folder wing seat includes the body being placed on cross bar, and body is connected with upper clamp plate and lower clamp plate, upper clamp plate and lower folder
Clamping opening is formed between plate.
The retaining mechanism includes center clamping screw and two caging bolts, and one end that clamping opening is sandwiched on the paddle is
Semicircle shape, center clamping screw pass through at the center of the end semicircle shape of paddle, and two caging bolts pass through the end half of paddle
The eccentric part of round shape, and two caging bolts are to be arranged symmetrically.
The trimmer is circle, and trimmer is equipped with the through-hole of arrangement corresponding with center clamping screw and caging bolt.
It is connected by rolling bearing between the folder wing seat and cross bar.
The folder wing seat is connected with angular adjustment connector.
Trimmer is equipped between the utility model paddle and clamping opening, trimmer can be adjusted according to different types of paddle
It is whole so that different types of paddle can be matched with paddle seat, this can need flexibly to replace paddle according to flight, easy to use
Fast.
