Abstract
The utility model discloses an unmanned aerial vehicle rotor arm connecting device, including the inside connecting pipe of connecting with the sleeve of the connection unmanned aerial vehicle rotor arm of cable, the rotor pipe that has the motor, connecting sleeve and rotor pipe that is equipped with, rotor pipe and telescopic relative inboard hold for rotor hub connection pipe and muffjoint respectively, rotor hub connection pipe hold with the muffjoint and be provided with respectively soon to opposite helicitic texture, the both ends of connecting pipe be equipped with respectively and hold the complex helicitic texture with rotor hub connection pipe and muffjoint. Rotor arm connection structure is adopted, the space of unmanned aerial vehicle when transportation or storage can be reduced.
Description
Technical field
The utility model relates to unmanned vehicles technical field, especially a kind of unmanned plane rotor arm connection structure.
Background technology
At present, small-sized many rotor wing unmanned aerial vehicles taking photo by plane, rescue, forest fire protection, a lot of field such as security protection be widely used.When carrying out the transport of unmanned plane, need to carry out dismounting to unmanned plane, thus save transport resource, when mounted, need to carry out rapid deployment to it, thus save time.
In order to connect rapidly the rotor arm of rotor wing unmanned aerial vehicle fast, usually the connection structure of rotor arm is needed to have quick and convenient structure of carrying out connecting, this structure not only can take apart rapidly and be fitted to each other, and there is constitutionally stable characteristic, with regard to the disassembly and assembly structure of the rotor arm of cyclogyro common at present, often all need more component to install, easily go wrong in the operation of reality, the situation that frequent generation spare and accessory parts are lost, and due to the speed of the comparatively complicated therefore Assembly &Disassembly of structure usually slow, be unfavorable for rapid-assembling and the dismounting of unmanned plane.
Utility model content
The technical matters that the utility model solves is by design unmanned plane rotor arm connection structure, thus saves the transport resource of unmanned plane, and its specific implementation process is as follows.
The technical matters that the utility model solves realizes by the following technical solutions:
Unmanned plane rotor arm connecting device, comprise inside and be provided with the sleeve of connection unmanned plane rotor arm of cable for connecting, the connection pipe of rotor pipe, coupling bush and the rotor pipe with motor, described rotor pipe is respectively rotor shaft connection pipe and sleeve connection end with the relative inner side of sleeve, described rotor shaft connection pipe and sleeve connection end are respectively arranged with the contrary helicitic texture of rotation direction, and the two ends of described connection pipe are respectively equipped with the helicitic texture coordinated with rotor shaft connection pipe and sleeve connection end.
In unmanned plane rotor arm connecting device of the present utility model, outside the cable in described sleeve, rotor pipe and connection pipe, be coated with wear-resisting magnesium aluminum alloy thin slice.When being outwarded winding by sleeve, sleeve and rotor pipe are in plumbness, and the coated cable of this magnesium aluminum alloy thin slice can not rupture because of bending.
In unmanned plane rotor arm connecting device of the present utility model, the helicitic texture of described sleeve, rotor pipe is respectively left-handed outside thread and the outside thread of dextrorotation, and the helicitic texture of the described connection pipe be connected with sleeve and rotor pipe is respectively left-handed and negative thread that is dextrorotation.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is: adopt telescopic connection structure, can dismantle and unmanned plane is installed by fast speed, be convenient to reduce the space when transporting or store, when needs are assembled, during use, the front and rear of rotor arm is directly put, fixing just passable with sleeve.

Detailed description of the invention
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Figure 1, unmanned plane rotor arm connecting device, comprise inside and be provided with the sleeve 2 of connection unmanned plane rotor arm of cable for connecting, the connection pipe 1 of rotor pipe 3, coupling bush 2 and the rotor pipe 3 with motor, described rotor pipe 3 is respectively rotor shaft connection pipe and sleeve connection end with the relative inner side of sleeve 2, described rotor shaft connection pipe and sleeve connection end are respectively arranged with the contrary helicitic texture of rotation direction, and the two ends of described connection pipe are respectively equipped with the helicitic texture coordinated with rotor shaft connection pipe and sleeve connection end.Wear-resisting magnesium aluminum alloy thin slice is coated with outside cable in described sleeve 2, rotor pipe 3 and connection pipe 1.The helicitic texture of described sleeve 2, rotor pipe 3 is respectively left-handed outside thread and the outside thread of dextrorotation, and the helicitic texture of the described connection pipe 1 be connected with sleeve 2 and rotor pipe 3 is respectively left-handed and negative thread that is dextrorotation.Cable wear-resistant magnesium aluminum alloy flake in unmanned plane rotor arm is coated; play protective effect; this alloy sheet can bear certain pulling force simultaneously; when sleeve is outwarded winding; connection pipe 1 and rotor pipe 3 are in plumbness, and the coated cable of this magnesium aluminum alloy thin slice can not rupture because of bending.In order to alleviate the weight of unmanned plane, the material of described sleeve 2, rotor pipe 3 and connection pipe 1 is magnesium aluminum alloy, and its structure is hollow structure.
More than show and describe groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
