Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of rotor wing unmanned aerial vehicle undercarriage of the present utility model is four groups（Being respectively arranged on has four rotors
Unmanned plane the lower section of horn 1.6）, every group of undercarriage include connecting shaft 1.1, steering wheel 1.2, undercarriage mobile jib 1.3, rotor protection
Device 1.4, double rocking lever structure and horn 1.6.Double rocking lever structure includes short rocking bar 1.8 and long rocking bar 1.5, short rocking bar 1.8 and length
It is hinged between rocking bar 1.5.With reference to Fig. 3, connecting shaft 1.1 and steering wheel 1.2 are screwed the horn 1.6 below motor
On, steering wheel 1.2 is connected with the transmission of short rocking bar 1.8, and long rocking bar 1.5 is connected with the top of undercarriage mobile jib 1.3, when driving steering wheel 1.2
Undercarriage mobile jib 1.3 can rotate around connecting shaft 1.1 during motion, realize packing up and putting down for undercarriage.
As shown in Fig. 2 rotor protection device 1.4 is the aluminum alloy frame of arc, including long segmental arc 1.4.1, short arc segments
1.4.2, pole 1.4.3.Long segmental arc 1.4.1 and short arc segments 1.4.2 dock to form bent frame structure, and short arc segments 1.4.2
Both ends are fixed in the middle part of long segmental arc 1.4.1.The lower end of undercarriage mobile jib 1.3 at long segmental arc 1.4.1 centers with being connected, pole 1.4.3
Both ends are separately fixed at short arc segments 1.4.2 centers and the bottom of undercarriage mobile jib 1.3.When gear down, rotor protection
The frame portion level of device 1.4 falls within bottom surface, plays support landing effect；When gear up, the meeting of undercarriage mobile jib 1.3
The position horizontal with horn 1.6 is presented, the arc aluminum alloy frame part of rotor protection device 1.4 can also play protection to rotor
Effect, as shown in Figure 2.
As shown in figure 3, undercarriage mobile jib 1.3 is connected on steering wheel 1.2 by double rocking lever structure, when steering wheel 1.2 drives
