Description
Technical field
The utility model relates to a kind of collapsible alighting gear of single steering engine of many rotor wing unmanned aerial vehicles.
Background technology
The collapsible alighting gear majority of other many rotor wing unmanned aerial vehicles adopts double steering engine multi-grade lever principle design, or the design of turbine and worm speed reducer, and shortcoming is that volume is large, power consumption is large, need outside independent control to work, relative weight is heavier simultaneously, the shortcomings such as mechanical clearance is bigger.
Utility model content
The purpose of this utility model is the collapsible alighting gear of single steering engine in order to provide a kind of many rotor wing unmanned aerial vehicles, and molar behavior is reliable, and excellent in stability is easy to operate, cost-saving, expendable weight, manufactures simple.
For achieving the above object, the technical solution of the utility model is:
The collapsible alighting gear of single steering engine of many rotor wing unmanned aerial vehicles, comprise and be arranged on alighting gear on fuselage, it is characterized in that: it comprises the monomer steering wheel be fixed on described fuselage, rocking arm is provided with at the mouth of described monomer steering wheel, the two ends of described rocking arm are connected with alighting gear by pull bar, and the upper end fulcrum of this alighting gear is flexibly connected with described fuselage; Connecting portion wherein between pull bar and described alighting gear is provided with movable plate.
Do further preferably the utility model, described pull bar is that elastic material is made.
The utility model is done further preferably, near the end of rocking arm on described pull bar, which is provided with point detection signal, described alighting gear is provided with signal head, described signal head sends horizontal signal, and when described point detection signal detection receives horizontal signal, described monomer steering wheel stops operation.
The utility model is done further preferably, between described pull bar and described monomer steering wheel, is provided with elastic pair bar.
Compared with prior art, the utility model has following beneficial effect:
1, the utility model arranges a monomer steering wheel on described fuselage, after adopting single steering engine principle of work, manufacturing cost significantly reduces, also relatively simple to the technological requirement of processing, do not need outside any equipment assistance, weight and consumption of current also significantly reduce, and leave more spaces, larger has played the internal capacity of unmanned aerial vehicle, extends the cruise duration of aircraft.
2, the utility model is provided with rocking arm at the mouth of described monomer steering wheel, and the two ends of described rocking arm are connected with alighting gear by pull bar, and the upper end fulcrum of this alighting gear is flexibly connected with described fuselage; Connecting portion wherein between pull bar and described alighting gear is provided with movable plate, and this spline structure is simple, and rocking arm and pull bar make all simple, and cost is low, simultaneously rocking arm and the whole alighting gear of the easy folding and unfolding of pull bar in operation process.
3, the utility model is provided with elastic pair bar between described pull bar and described monomer steering wheel, can increase the stability in whole folding and unfolding operation process, improves folding and unfolding reliable in action and stablizes.
As from the foregoing, the utility model molar behavior is reliable, and excellent in stability is easy to operate, cost-saving, expendable weight, manufactures simple.
In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to accompanying drawing 1, present embodiment discloses a kind of collapsible alighting gear of single steering engine of many rotor wing unmanned aerial vehicles, comprise and be arranged on alighting gear 1 on fuselage, it is characterized in that: comprise the monomer steering wheel 2 be fixed on described fuselage, Rocker arm 4 is provided with at the mouth 3 of described monomer steering wheel 2, the two ends of described Rocker arm 4 are connected with alighting gear 1 by pull bar 5, and the upper end fulcrum 6 of this alighting gear 1 is flexibly connected with described fuselage; Connecting portion wherein between pull bar 5 and described alighting gear 1 is provided with movable plate 7.
Do further preferably to the utility model, described pull bar 5 is made for elastic material.
The utility model is done further preferably, near the end of Rocker arm 4 on described pull bar 5, which is provided with point detection signal 8, described alighting gear 1 is provided with signal head 9, described signal head 9 sends horizontal signal, when described point detection signal 8 detection receives horizontal signal, described monomer steering wheel 2 stops operation.
The utility model is done further preferably, between described pull bar 5 and described monomer steering wheel 2, is provided with elastic pair bar 10.
The utility model in actual use, after adopting single steering engine principle of work, manufacturing cost significantly reduces, also relatively simple to the technological requirement of processing, do not need outside any equipment assistance, weight and consumption of current also significantly reduce, and leave more spaces, larger has played the internal capacity of unmanned aerial vehicle, extends the cruise duration of aircraft.When needs are put, as long as open monomer steering wheel 2, hold pull bar 5 by Rocker arm 4 and can open alighting gear 1, amplitude struts maximum.When needs are received, as long as monomer steering wheel 2 can pack up alighting gear 1 by Rocker arm 4 and pull bar 5, in the process of packing up, when described point detection signal 8 detection receives horizontal signal, described monomer steering wheel 2 stops operation.
The utility model molar behavior is reliable, and excellent in stability is easy to operate, cost-saving, expendable weight, manufactures simple.
The foregoing is only an embodiment of the present utility model, not to the restriction of this case design, all equivalent variations done according to the design key of this case, all fall into the protection domain of this case.
