Embodiment
To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
As shown in figure 1, the utility model provides a kind of light-duty fixed-wing unmanned plane undercarriage, the light-duty fixed-wing nobody
Machine undercarriage includes pillar 1, connecting plate 2, flexible member 3 and connecting lever 4；Wherein, the upper end of pillar 1 is used to be connected with unmanned plane,
The lower end of pillar 1 is connected with connecting plate 2, and the first end of connecting plate 2 is connected with the first end of flexible member 3, and the of connecting plate 2
Two ends are connected with the pars convoluta of connecting lever 4, and the second end of flexible member 3 connects with the first end of connecting lever 4, and the second end of connecting lever 4 connects
It is connected to wheel 5；Connecting lever 4 is applied to make counterclockwise motion in light-duty fixed-wing UAV Landing, tensile elasticity element 3, one section
After time, make clockwise motion because flexible member 3 shrinks.
As illustrated in fig. 1, it is preferred that the lower end of pillar 1 is connected between the first end of connecting plate 2 and the second end, connecting lever 4
Pars convoluta is located between first end and the second end of connecting lever 4, and said structure is advantageous to the damping of undercarriage.
As shown in figure 1, pillar 1 is direction bearing, mainly played a supportive role in light-duty fixed-wing UAV Landing, and
Steering-effecting from during light-duty fixed-wing unmanned plane changing location.
As shown in figure 1, connecting plate 2 is obtuse triangle sheet material obliquely, suitable in light-duty fixed-wing unmanned plane
Lu Shi, reduce between connecting lever 4 and connecting plate 2 because of relative motion and caused by frictional force, effect of the ground in face of undercarriage is overcome
The elastic potential energy of flexible member 3 may be converted into more, further improve the damping effect to undercarriage.
As shown in figure 1, damping structure is connected between pillar 1 and connecting plate 2, suitable in light-duty fixed-wing unmanned plane
Lu Shi, further cut down influence of the vibrations to landing gear structure, extend the service life of undercarriage.
As shown in figure 1, flexible member 3 is spring or rubber band, suitable in light-duty fixed-wing UAV Landing, elasticity is first
For part 3 if spring, the tensility of spring and high-strength recovery can ensure that the buffer time of connecting lever 4；Flexible member 3 if
Rubber band, the super tensility of rubber band and soft recovery further extend the buffer time of connecting lever 4.
As shown in figure 1, connecting lever 4 includes long arm, pars convoluta and galianconism portion, wherein, the pars convoluta is connected to the long arm
Between the galianconism portion；Wheel 5 is connected to the end of the long arm；Second end of flexible member 3 is connected to the galianconism
The end in portion；The length of the long arm is 2 times of the galianconism minister degree；Suitable in light-duty fixed-wing UAV Landing
When, undercarriage supports to the high intensity of light-duty fixed-wing unmanned plane.
As shown in figure 1, the axis of pillar 1 is arranged in front of the axle center of wheel 5, to obtain preferable damping effect, it is applicable
When in light-duty fixed-wing UAV Landing, connecting lever 4 faces easily to be moved counterclockwise in the presence of undercarriage impulsive force on ground
Make, the more steady elastic potential energy for being rapidly converted into flexible member 3 of active force by ground in face of undercarriage.
As shown in Fig. 2 when light-duty fixed-wing UAV Landing, speed is gradually reduced, between undercarriage and ground
Interaction force gradually increase, the counterclockwise motion of connecting lever 4 and tensile elasticity element 3, flexible member 3 absorb impulsive force；When light
After type fixed-wing unmanned plane is comfortableed touchdown, the interaction force between undercarriage and ground is gradually reduced, and flexible member 3 is being replied
Started to shrink in the presence of power, drive the clockwise motion of connecting lever 4, until undercarriage state back to normal, as shown in Figure 1.At this
During individual, light-duty fixed-wing unmanned plane is converted into the elastic potential energy of flexible member 3 to the impulsive force on ground, afterwards elastic potential energy
Release, flexible member 3 reply original state, light-duty fixed-wing unmanned plane grease it in.
Therefore, during the light-duty fixed-wing UAV Landing of the utility model, due to using flexible member and connecting lever, greatly subtract
The impulsive force that light ground is applied by wheel to undercarriage, extends the stress time, slow down the impact journey in landing mission
Degree, enables the service life of light-duty fixed-wing unmanned plane to increase.
