Abstract
The utility model provides a pair of rotor flight arm, this rotor flight arm detachable install on the fuselage of aircraft, this rotor flight arm include support arm, at least one motor and by motor drive's screw, the back tip detachably of support arm connects on the fuselage of aircraft, the tip center pin is to extending an inserted bar behind the support arm, be equipped with on the aircraft fuselage that corresponds with support arm center inserted bar matched with jack, the utility model discloses an aircraft that adopts rotor flight arm that still provides.
Description
[technical field]
The utility model relates to unmanned aviation flight technology, particularly relates to a kind of rotor flying arm and aircraft thereof.
[background technology]
Be generally all one-body molded between the fuselage of existing multi-rotor aerocraft and horn, so just cause body volume large, be not easy to packaging and transport, carry also extremely inconvenient.
For above problem, designer adopts fuselage and horn separate machined, adopt the connection mode of two independent component combinations, by screw, fuselage is fixedly connected with integral with horn during assembling, when this just causes the installation or removal between fuselage and horn, need use special instrument (as electric screw driver) by screw-driving or unscrew, thus realize the installation or removal of fuselage and horn.When screw number is too much, tightens one by one by specialist tools or unscrew screw, certainly will bother, time-consuming, inefficiency.
[utility model content]
The utility model provides a kind of Assembly &Disassembly rotor flying arm and aircraft thereof easily.
In order to realize foregoing invention object, the technical solution adopted in the utility model is:
A kind of rotor flying arm, this rotor flying arm detouchable is installed on the fuselage of aircraft, this rotor flying arm comprises hold-down arm, at least one motor and by described motor-driven screw propeller, and the rearward end of described hold-down arm is removably connected on the fuselage of aircraft; Described hold-down arm rearward end center shaft is to extending an inserted link, and corresponding aircraft fuselage is provided with the jack matched with hold-down arm center inserted link.
Preferably, the inserted link on described hold-down arm is the body of rod of a hollow.
Preferably, the fuselage junction of described hold-down arm and aircraft is also provided with and locks the locking mechanism of inserted link in fuselage jack.
Preferably, described locking mechanism be aircraft fuselage on be fixed with the locking pin of inserted link in fuselage jack.
Preferably, described hold-down arm and the fuselage junction of aircraft are also provided with the buckle structure being convenient to be fixedly connected with to the periphery in both weeks.
Preferably, described buckle structure is the fuselage junction week of aircraft inwardly shrink the step-like plush copper of formation one to the periphery, and corresponding hold-down arm rear end is recessed to form a draw-in groove coordinated with plush copper.
Aircraft, this aircraft adopts above-mentioned a kind of rotor flying arm.
The beneficial effects of the utility model are:
The rotor flying arm that the utility model provides, by arranging the structure that jack coordinates between hold-down arm with aircraft fuselage, and hold-down arm is provided with the fuselage junction of aircraft the buckle structure being convenient to be fixedly connected with to the periphery in both weeks, install or remove very convenient, free-handly get final product complete operation, do not need to adopt specialist tools to install or remove, simple to operate, time saving and energy saving.Hold-down arm and aircraft fuselage conveniently transport and carry after dismantling; And after hold-down arm and aircraft fuselage be installed together, buckle structure between hold-down arm and aircraft fuselage makes locking effect better, locking mechanism further by pin locks inserted link in fuselage jack, and aircraft of the present utility model can be enable effectively to adapt to the flight environment of vehicle of high vibration.
[accompanying drawing explanation]
Fig. 1 is the structure for amplifying schematic diagram of the utility model rotor flying arm;
Fig. 2 is the annexation schematic diagram of the utility model rotor flying arm and aircraft.
[detailed description of the invention]
A kind of rotor flying arm, as depicted in figs. 1 and 2, this rotor flying arm detouchable is installed on the fuselage 1 of aircraft, the screw propeller 4 that this rotor flying arm comprises hold-down arm 2, motor 3 and driven by described motor 3, motor 3 is installed on the top of hold-down arm 2, and the rearward end of hold-down arm 2 is removably connected on the fuselage 1 of aircraft; Hold-down arm 2 rearward end center shaft is to extending an inserted link 5, and corresponding aircraft fuselage 1 is provided with the jack 6 matched with hold-down arm 2 center inserted link 5; Wherein, inserted link 5 is the body of rod of a hollow.
As shown in Figure 2, hold-down arm 2 is also provided with fuselage 1 junction of aircraft and lock the locking mechanism of inserted link 5 in fuselage 2 jack 6, locking mechanism be aircraft fuselage 2 on be fixed with and lock the pin (not shown) of inserted link 5 in fuselage 1 jack 6.
Continue as shown in Figure 2, hold-down arm 2 and fuselage 1 junction of aircraft are also provided with the buckle structure being convenient to be fixedly connected with to the periphery in both weeks, buckle structure is the fuselage 1 junction week of aircraft inwardly shrink the step-like plush copper 7 of formation one to the periphery, and corresponding hold-down arm 2 rear end is recessed to form a draw-in groove 20 coordinated with plush copper 7.
By arranging the structure that jack coordinates between hold-down arm 2 with aircraft fuselage 1, and hold-down arm 2 is provided with fuselage 1 junction of aircraft the buckle structure being convenient to be fixedly connected with to the periphery in both weeks, install or remove very convenient, free-handly get final product complete operation, do not need to adopt specialist tools to install or remove, simple to operate, time saving and energy saving.In addition, hold-down arm 2 and aircraft fuselage 1 conveniently transport and carry after dismantling; After hold-down arm 2 and aircraft fuselage 1 are installed together simultaneously, buckle structure between hold-down arm 2 and aircraft fuselage 1 makes locking effect better, lock inserted link 5 further in fuselage 1 jack 6 by pin, aircraft can be enable effectively to adapt to the flight environment of vehicle of high vibration.
The above embodiment is just preferred embodiment of the present utility model, not limits practical range of the present utility model with this, the equivalence change that all shapes according to the utility model, structure and principle are done, and all should be covered by protection domain of the present utility model.
