Abstract
The invention relates to a landing assistant device of an unmanned aerial vehicle, in particular to a buffering connecting rod of a landing assistant parachute of the unmanned aerial vehicle. The connecting rod comprises a hollow tubular structural rod body, a tensile force buffering assembly is arranged in the rod body, and a parachute connecting part and an airframe connecting part are arranged at the two ends of the tensile force buffering assembly respectively. The buffering connecting rod of the landing assistant parachute of the unmanned aerial vehicle solves the problem that damage to the parachute rope connecting part and an airframe structure can be caused easily by impact force after the landing assistant parachute is unfolded in the prior art, direct acting force reaching an airframe after the impact force passes through the buffer device can be reduced greatly, and the function that the fragile airframe structure of the unmanned aerial vehicle can be protected effectively can be performed.
Description
Technical field
The present invention relates to a kind of unmanned vehicle auxiliary landing device, umbrella buffering pipe link falls in especially a kind of unmanned machine aided.
Background technology
Along with increasing unmanned plane, model plane, aerial photography aircraft is applied in civil area, this type of unmanned vehicle is due to the continuous increase of function and ceiling voyage, the weight and volume of unmanned vehicle self is also in continuous increase, and the alighting gear of this type of unmanned vehicle has been difficult to bear such weight, cause in the process of rear landing of having flown, occur that alighting gear loses and then make aircraft to occur the damage of structure and outward appearance.Unmanned vehicle special utility parachute is given birth to for solving problems just, and its object is to help aircraft in landing process, significantly to reduce vertical and horizontal velocity, makes unmanned vehicle when landing is contacted to earth, reduce to impact.
And existing helping fallen umbrella in use, when the moment that umbrella is opened, umbrella and aircraft all can be received larger impulsive force, in order to ensure helping, fall successfully, existing helping fallen umbrella and generally all progressively improved umbrella rope intensity, but ignore carry-on helping, falls umbrella connecting portion and also bears larger impact, and the intensity of umbrella rope is higher, cause the stressed larger of aircraft connecting portion, tend to cause distortion, affect the bulk strength of aircraft.
Summary of the invention
The invention provides a kind of not only guaranteed effectively to help fall, but also reduce the unmanned machine aided of the impulsive force of umbrella and aircraft to fall umbrella buffering pipe link.
To achieve these goals, the present invention adopts following technical scheme:
The body of rod that comprises a hollow tubular structure, is provided with a pulling force buffer assembly in the described body of rod, pulling force buffer assembly two ends are respectively equipped with umbrella connecting portion and fuselage connecting portion.
Preferably, described fuselage connecting portion is a fixed link being connected with pulling force buffer assembly.
Preferably, the end of described fixed link is provided with fuselage fixed bit.
Preferably, described fuselage fixed bit is a set collar.
Preferably, described fixed link and set collar are integral type structure.
Preferably, described umbrella connecting portion is one for the fixing wire harness fixed part of umbrella rope.
Preferably, described pulling force buffer assembly is spring.
Preferably, described pulling force buffer assembly is hydraulic pressure draw-bar.
Preferably, the described body of rod is pipe.
Preferably, described body of rod length is 40-60cm.
Owing to having adopted said structure; unmanned machine aided of the present invention fall umbrella buffering pipe link solved in prior art, exist help umbrella parachute-opening is fallen and after impulsive force for unmanned vehicle umbrella rope junction and housing construction, easily cause the problem of damage; impulsive force will greatly reduce in the direct effect power that arrives airframe after shock absorber, can play the effect of the fragile housing construction of effective protection unmanned vehicle.
Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of the embodiment of the present invention.
The specific embodiment
As shown in Figure 1, the body of rod 1 that umbrella buffering pipe link comprises a hollow tubular structure falls in the unmanned machine aided of the present embodiment, is provided with a pulling force buffer assembly 2 in the described body of rod 1, and pulling force buffer assembly 2 two ends are respectively equipped with umbrella connecting portion 3 and fuselage connecting portion 4.
Concrete, in the present embodiment, described fuselage connecting portion 4 is a fixed link being connected with pulling force buffer assembly.
In the present embodiment, the end of described fixed link is provided with fuselage fixed bit 5.
In the present embodiment, described fuselage fixed bit 5 is a set collar.
In order to improve tensile property, improve the stability of using, in the present embodiment, described fixed link and set collar are integral type structure.
In the present embodiment, described umbrella connecting portion 3 is one for the fixing wire harness fixed part of umbrella rope.
In the present embodiment, described pulling force buffer assembly 4 is spring.
In the present embodiment, described pulling force buffer assembly 4 is hydraulic pressure draw-bar.
Spring and hydraulic pressure draw-bar are two possibilities, and in figure, a hydraulic pressure draw-bar is that example is described concrete structure, while using spring, substitute hydraulic pressure draw-bar.
In addition, in the present embodiment, the described body of rod 1 is pipe.
In the present embodiment, described 1 body of rod length is 40-60cm.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification sheets of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
