Abstract
A kind of concertina type protection device of unmanned plane screw wing, it is made up of screw wing, hollow unmanned plane horn, piston, lightweight pole, spring assembly and lightweight flexible fork-type arm.It is characterized in that：Screw wing is placed on hollow unmanned plane horn；By spring assembly with lightweight flexible fork-type arm with being connected, the other end of lightweight pole is connected with piston for one end of lightweight pole；Piston is embedded in hollow unmanned plane horn, can be moved back and forth by spring assembly with lightweight pole, and then realizes the flexible contraction of lightweight flexible fork-type arm.The utility model plays the protective effect to screw wing using lightweight flexible fork-type arm, solves the problems, such as weight increase caused by extra unmanned plane protection device and flight resistance increase, so as to improve the control accuracy of unmanned plane.
Description
Technical field
Unmanned air vehicle technique field is the utility model is related to, dress is protected more particularly to a kind of concertina type of unmanned plane rotor
Put.
Background technology
In the last few years, unmanned air vehicle technique was rapidly developed, but unmanned plane is likely to occur nothing during flight
Man-machine screw wing is impaired and then causes the event of unmanned plane crash.How screw wing is prevented to be damaged during unmanned plane during flying
It is that a comparison is popular to study a question, common safeguard procedures are to add an extra protection device to unmanned plane, still
The problems such as so causing the increase of unmanned plane volume, weight increase, the resistance increase of flight and unmanned aerial vehicle (UAV) control precision to reduce.
Utility model content
In summary, the new purpose of this reality is to provide a kind of concertina type protection device of unmanned plane rotor.
The purpose of this utility model is realized by following technology：
A kind of concertina type protection device of unmanned plane rotor, it is by screw wing, hollow unmanned plane horn, piston, lightweight
Pole, spring assembly and lightweight flexible fork-type arm composition.
It is characterized in that：
(1) screw wing is placed on hollow unmanned plane horn.
(2) one end of lightweight pole by spring assembly with lightweight flexible fork-type arm with being connected, the other end of lightweight pole
It is connected with piston.
(3) piston is embedded in hollow unmanned plane horn, can be moved back and forth by spring assembly with lightweight pole,
And then realize the flexible contraction of lightweight flexible fork-type arm.
The advantages of the utility model and beneficial effect：
1st, the utility model can utilize lightweight flexible fork-type arm when accident collision occurs during unmanned plane during flying
The protective effect to screw wing is played, and the elastic deformation occurred using lightweight flexible fork-type arm in collision is collided to absorb
When caused energy, the loss of unmanned plane can be effectively reduced.
2nd, the utility model utilizes lightweight pole and lightweight flexible fork-type arm, can efficiently solve extra unmanned plane protection
The problem of weight increase and flight resistance increase caused by device, so as to improve the control accuracy of unmanned plane.
3rd, lightweight flexible fork-type arm is accommodated in hollow nothing by the utility model using spring assembly, lightweight pole and piston
In man-machine horn, the original mode of appearance of unmanned plane can be kept, and can is solved caused by extra unmanned plane protection device
Volume increases problem, is easy to daily placement.
4th, the utility model is simple in construction, easy to operation, and cost is cheap, significant effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- screw wings；Unmanned plane horn hollow 2-；3- pistons；4- lightweight poles；5- spring assemblies；6- lightweights
Elastic fork-type arm.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of concertina type protection device of unmanned plane rotor, is by screw wing 1, hollow unmanned plane horn
2nd, piston 3, lightweight pole 4, spring assembly 5, lightweight flexible fork-type arm 6 form.Wherein, screw wing 1 is placed in nobody hollow
On machine horn 2.One end of lightweight pole 4 by spring assembly 5 with lightweight flexible fork-type arm 6 with being connected, lightweight pole 4 it is another
End is connected with piston 3.Piston 3 is embedded in hollow unmanned plane horn 2, by spring assembly 5 can with lightweight pole 4 come
Return is dynamic, and then realizes the flexible contraction of lightweight flexible fork-type arm 6.
Embodiment
Before unmanned plane is let fly away, the lightweight flexible forked type being placed in hollow unmanned plane horn 2 can be manually pulled out
Arm 6, until being flicked completely under triple role of the lightweight flexible fork-type arm 6 in lightweight pole 4, spring assembly 5 and piston 3；So,
Unmanned plane can drives safely under the protection of the device；After unmanned plane during flying terminates, then lightweight flexible is pitched manually
Arm is pushed into hollow unmanned plane horn and stored, for future use.
Claims (1)
1. a kind of concertina type protection device of unmanned plane screw wing, it is by screw wing (1), hollow unmanned plane horn (2), piston
(3), lightweight pole (4), spring assembly (5) and lightweight flexible fork-type arm (6) composition, it is characterized in that：Screw wing (1) is placed in sky
