Description
Technical field
The present invention relates to unmanned air vehicle technique field is and in particular to a kind of foldable rotor support of unmanned plane.
Background technology
The now rotor support of small-sized many rotor wing unmanned aerial vehicles of main flow and for supporting rotor and rotor support on the market
Mobile jib is all directly to stretch out and fixing, so leads to the overall profile ratio of unmanned plane larger, is not easy to receive and carry；It is based on
This, in order that unmanned plane miniaturization being convenient for carrying it is necessary to develop a kind of foldable rotor support of unmanned plane.
Content of the invention
In view of this, the invention discloses a kind of foldable rotor support of unmanned plane, open when needing flight and can roll over
Folded rotor support, flight finishes and is folded, and after folding, unmanned plane volume reduces, and is convenient for carrying.
Technical scheme is as follows:
A kind of foldable rotor support of unmanned plane, including the power spin oar support being made up of elastomeric material, for
The fixing frame connection fixture of frame；The bottom of described power spin oar support is propeller fixed part, and its top is provided with one
Rotation post, is provided with least one with axially in parallel raised line outside described rotation post, the middle part of described frame connection fixture be provided with
The cylindrical hole of described rotation post coupling, the wall of described cylindrical hole is provided with least two grooves corresponding with described raised line；Described rotation
Post upper end is provided with clamping ring, and described cylindrical hole upper end is provided with the boss mating with described clamping ring, and described rotation column sleeve is connected to described
Cylindricality in the hole, the end of rotation post is fixed by described boss and described clamping ring.
Preferably, described power spin oar support and/or described frame connection fixture are made of plastics.
Preferably, the raised line outside described rotation post is two and is spaced 180 ° of settings；Groove on described cylindricality hole wall
For four and be set at 90 ° intervals.
Unmanned plane overall volume can be made after the foldable rotor support-folding of unmanned plane disclosed by the invention to reduce, convenient
Carry transport；And fold mechanism is fairly simple, spring equal power device need not be added, when directly folding or opening, pass through elastic
Distorting tension between part is fixed, and awing relies on the cooperation between elastomeric element being capable of very stable strutting after opening；And
Also wing can be made after folding to be fitted in well above frame, also will not automatically spring open under there is no external force effect, using can
Lean on.
Brief description
Fig. 1 is present invention decomposition texture schematic diagram in one embodiment.
Specific embodiment
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is elaborated.
As shown in figure 1, the foldable rotor support of unmanned plane disclosed by the invention includes the power being made up of elastomeric material
Propeller bracket 1, the frame connection fixture 8 for fixing with frame, for example, in being embodied as, described power spin oar
Support 1 and/or described frame connection fixture 8 are made of plastics so as to have certain elasticity, are made using plastic material simultaneously
Its lighter in weight, is easy to mitigate the weight of unmanned plane；The bottom of described power spin oar support 1 is propeller fixed part, thereon
Portion is provided with a rotation post 2, and the outside of described rotation post 2 is provided with least one and axially in parallel raised line 3, described frame connection fixture
8 middle part is provided with the cylindrical hole 5 mating with described rotation post 2, and the wall of described cylindrical hole 5 is provided with least two and described raised line 3
Corresponding groove 6；Described rotation post 2 upper end is provided with clamping ring 4, and described cylindrical hole 5 upper end is provided with convex with what described clamping ring 4 mated
Platform 7, described rotation post 2 is socketed in described cylindrical hole 5, and the end of rotation post 2 is fixing by described boss 7 and described clamping ring 4, makes
It is axially positioned；
In a preferred embodiment, the raised line 3 in described rotation post 2 outside is two and is spaced 180 ° of settings；Described cylindrical hole 5
Groove 6 on wall is four and is set at 90 ° intervals, and in use, two raised lines 3 are remembered with during two of which groove 6 clamping
For position a, for example, in being embodied as, position a is set to position when power spin oar support 1 is opened, then two raised lines 3 with
It is designated as position b, position b corresponds to position during power spin oar support 1 storage during two other groove 6 clamping；Power spin
Oar support 1 rotates 90 ° to position b from position a, completes to receive；If opening, otherwise；
Unmanned plane overall volume can be made after the foldable rotor support-folding of unmanned plane disclosed by the invention to reduce, convenient
Carry transport；And fold mechanism is fairly simple, spring equal power device need not be added, when directly folding or opening, pass through elastic
Distorting tension between part is fixed, and awing relies on the cooperation between elastomeric element being capable of very stable strutting after opening；And
Also wing can be made after folding to be fitted in well above frame, also will not automatically spring open under there is no external force effect, using can
Lean on.
Invention described above embodiment, does not constitute limiting the scope of the present invention.Any in the present invention
Spirit and principle within modification, equivalent and improvement of being made etc., should be included in the claim protection model of the present invention
Within enclosing.
