Description
Technical field
This utility model belongs to unmanned vehicle security fields, particularly relates to a kind of unmanned vehicle fender bracket and nothing thereof
People's aircraft.
Background technology
The application of unmanned vehicle is the most constantly expanded, and either industry unmanned plane is still consumed unmanned plane and all obtained
Significant progress, especially many rotary wind types unmanned vehicle are the little miniature unmanned vehicle of representative, and its various ingredients are opened
Beginning modularity, industry reaches its maturity.
At present, many rotor wing unmanned aerial vehicles taking photo by plane, rescue, forest fire protection, a lot of fields such as security protection are widely used,
It is mainly made up of rotor fuselage, multiple electric motors and multi-blade propeller, wherein has multi-disc with gyroplane and is arranged radially
Frame, every frame outer end upper surface is provided with a motor, and connects a leaf spiral shell on the output shaft of every motor upper end
Rotation oar.Owing to the flight performance of multi-rotor aerocraft constantly promotes, it is desirable to its rotor rotating speed is increasingly faster, and flying quality
Promoting makes the speed of aircraft also become faster, and in the case, if once there is maloperation, obstacle encountered by aircraft
Thing, then the rotor of aircraft will be damaged and even fall, and if meet people, the rotor of high speed rotating be also possible to wound
Victimization body.
Existing rotor fender bracket structure can be to be divided into two kinds of forms, and one is as one with frame or other airframe components
Body, is not required to install, it is impossible to the rotor fender bracket of dismounting；Another kind is to install before flight, but this typically requires dismounting
Multiple screws.There is clearly disadvantageous part in both fender brackets: the former causes unmanned plane volume to increase, not readily portable and deposit
Put；The latter dismounts trouble, has a strong impact on convenience and reliability that user uses.
Propeller top guard disclosed in patent documentation CN205150236U, including the matrix being located on the upside of unmanned plane
(2), matrix mediad swells, entreat bottom to form receiving chamber (21) in the base；Centered by accommodating chamber, matrix is uniformly opened
Having at least two through hole (20), be provided with protective cover (1) in through hole, protective cover is connected with unmanned plane body.This patent can be avoided
Barrier infringement unmanned plane propeller, is avoided that again the situation that unmanned plane is hurted sb.'s feelings occurs.But this patent causes unmanned plane volume to increase
Greatly, not readily portable and deposit, and increase windage, reduce flying quality.
Unmanned plane disclosed in patent CN205150235U props up support component and includes one-time formed base (2), horn (1) and electricity
Support (4), horn two ends connect base and motor cabinet respectively, and motor cabinet includes the cavity of open lower side, and cavity inside passes through spiral shell
Bolt is connected with and protects oar seat (5), protects clamping on the downside of oar seat and protects oar (3).This patent improves the integrated level of whole unmanned plane body, subtracts
Lack disassembly and assembly time.But it causes unmanned plane volume to increase, not readily portable and deposit, and increase windage, reduce flight
Energy.
A kind of many rotor wing unmanned aerial vehicles protection device disclosed in patent documentation CN205131658U include circular fender bracket (1),
Multiple connection supports (2) and multiple bilateral adapter (3)；Wherein connecting support (2) is the strip being made up of carbon fibre material
Platy structure, middle part is formed with lightening hole (4), and one end of each connection support (2) is fixed on a piece of machine on many rotor wing unmanned aerial vehicles
Between outer end face and motor (6) lower end of frame (5), other end surface is provided with a bilateral adapter (3)；Bilateral adapter
(3) being round tube shape structure, its two ends are positioned at the left and right sides connecting support (2)；Circular fender bracket (1) is circular pin, inserts simultaneously
Enter the inside above-mentioned multiple bilateral adapters (3).This patent can avoid barrier to damage unmanned plane propeller, is avoided that again nothing
Man-machine situation about hurting sb.'s feelings occurs.But this patent causes unmanned plane volume to increase, not readily portable and deposit, and increase windage and weight
Amount, reduces flying quality.
Disclosed in patent documentation CN104986331A, a kind of unmanned plane rotor fender bracket includes: fender bracket body, detachably
Be arranged on unmanned plane horn (4) end, one end away from unmanned plane body, described end is provided with propeller (5), described
The rotation axis of propeller (5) is perpendicular to the surface of described fender bracket body, and described fender bracket body is for institute when rotating
State propeller (5) to protect.This patent can Fast Installation and dismounting, convenient for collecting carries, during use can rapid deployment,
It is rapidly reached state of flight.But this patent poor reliability, increases windage and weight, reduces flying quality.
Rotor fender bracket of the prior art is typically to be removably mounted at outward extending four cantilevers of frame main body
Edge, but current fender bracket is typically the structure of similar triangle, is wherein connected with cantilever edge at the acute angle of triangle,
The another side (protection limit) of the triangle relative with this acute angle, it is common that formed round outward flange during with rotor wing rotation and coincide,
And it is slightly more than this circle.So, the protection limit of fender bracket act as the effect of guardrail outside rotor, it is possible to avoids rotor direct
Strike barrier.But, no matter this fender bracket is to design in the underface of above-mentioned rotor or surface, due to fender bracket
Several muscle structures are just kept off on the wind path of rotor, thus will reduce rotor caned to aircraft provide flying quality,
In some cases, this obstruction ability even can reach the level of 30%.So, somewhat specialty any fly hands, it would be desirable to
This fender bracket can not be used such that it is able to enjoyment high-speed flight carefully.So, the flight safety of aircraft is also reduced
Property.
Therefore, urgency technical issues that need to address in this area are: be not resulted in the situation that unmanned vehicle volume increases
Under, it is to avoid barrier infringement unmanned plane propeller, it is avoided that again the situation that unmanned plane is hurted sb.'s feelings occurs, it is to avoid increase unmanned vehicle
Weight and windage, and do not affect the flying quality of unmanned vehicle.
Disclosed above-mentioned information is used only for strengthening the understanding to this utility model background in the background section, therefore
May comprise and not be formed in the information of prior art known to a person of ordinary skill in the art in this country.
