Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Embodiments provide a kind of unmanned plane, see Fig. 1 ~ 5, this unmanned plane comprises: fuselage 1, be located at two groups of screw propellers 21 of head, be located at two groups of screw propellers 22 of tail, for screw propeller provides the engine installation 3 of power, the power supply (not shown) be electrically connected with engine installation 3, and be placed in multiple booms 4 that rise and fall of fuselage 1 both sides respectively, each boom 4 that rises and falls is connected with unmanned aerial vehicle body 1 respectively by a power fold mechanism 5, and each boom 4 that rises and falls is provided with at least two wheels 6, two spiral 22 oars being located at tail are connected with fuselage 1 by a rotatable transverse axis 7, unmanned plane alighting gear also comprises:
Motor (not shown), for providing power for rotatable transverse axis rotates;
Control setup (not shown), folds for controlling power fold mechanism, and by controlling motor, is in horizontal or vertical direction to adjust the two groups of screw propellers being located at tail;
Above-mentioned power supply, motor and control setup are placed in fuselage, and control setup is electrically connected with power supply, power fold mechanism 5 and motor respectively.
Wherein, this power fold mechanism 5 is metal steering base.Preferably, be subject to the impact of external environment little when metal steering base is used for this unmanned plane alighting gear.
Particularly, the steering angle scope of metal steering base is 0 ~ 45 degree.Steering angle refers to, boom 4 rotating angle under metal steering base drives of rising and falling.This steering angle can realize rising and falling on the basis of boom folding and unfolding, and boom movement range scope of rising and falling is little, makes the present embodiment unmanned plane alighting gear realize windage reduction, lower power consumption in folding and unfolding process.Wherein, boom collapsed state is risen and fallen see Fig. 2.
Particularly, each boom 4 that rises and falls comprises first boom 41 and second that rises and falls and to rise and fall boom 42, first one end of rising and falling boom 41 is connected with power fold mechanism 5, first other end rising and falling boom 41 is connected with second one end of rising and falling boom 42, wherein, the first rise and fall boom 41 and the second angle risen and fallen between boom 42 is 90 ~ 135 degree.Because this boom that rises and falls is divided into two parts, and the angle between two parts can ensure that second boom 42 that rises and falls reliablely and stablely is parked on the ground when putting down, can ensure again second rise and fall boom 42 when packing up and the screw propeller at fuselage 1 two ends (comprising the two groups of screw propellers 21 being located at head and the two groups of screw propellers 22 being located at tail) keep certain distance d (d ﹥ 0), be subject to second boom 42 that rises and falls to avoid screw propeller and pack up shock in process.
Further, first rises and falls boom 41 for telescopic arms, and control setup is also for controlling the first length of rising and falling boom 41.Control setup is risen and fallen by control first length of boom 41, can realize the control in the direction to wheel 6, thus when unmanned plane is at ground run or when sliding, can control the direction of unmanned plane, as shown in Figure 3.
Preferably, first boom 41 is risen and fallen for hydraulic stem.
Further, be positioned at the rise and fall other end of boom 42 of second of fuselage homonymy and be interconnected by the 3rd boom 43 that rises and falls, wheel 6 is located at the 3rd and is risen and fallen on boom 43.This first boom 41, second boom 42 and the 3rd boom 43 that rises and falls that rises and falls that rises and falls complements each other to form stable supporting construction.
Further, this unmanned plane also comprise detection second rise and fall boom 42 degree of packing up with put down the sensor 8 of degree, sensor 8 is positioned at second and rises and falls on boom 42, and sensor 8 is electrically connected with control setup.Sensor 8 can this second state of rising and falling boom 42 of real-time detection, and control setup accurately controls the steering angle of power fold mechanism 5 according to the detection data of this sensor 8, makes second the rise and fall its stored position of boom 42 more accurate.
Preferably, sensor is inductive pickoff.This inductive pickoff adopts non-contacting detection mode ensure that, and sensor can not wear and tear or be shifted.
Preferably, control setup can be microcomputer.
As from the foregoing, when unmanned plane is when flying, control setup controls power fold mechanism and upwards folds, and then drives the boom that rises and falls to pack up; When unmanned plane grounds, control setup controls power fold mechanism and folds downwards, and then drives the boom that rises and falls to put down.See Fig. 4 and Fig. 5, when unmanned plane needs at ground run, control setup controls fold mechanism and folds downwards, and then drive the boom that rises and falls to put down, and control motor and make the screw propeller being located at tail be in vertical state, then control the propeller rotational being located at tail, the screw propeller being located at head does not rotate, thus unmanned plane can be slided forward, control the first length of rising and falling boom simultaneously and realize turning to.
Easily know, in other implementation, the screw propeller being located at head also can also be made the pattern that can turn to, thus provide power for unmanned plane during ground run, in addition, the boom that also can rise and fall second is set as telescopic arms to control travel direction.
The present invention is connected with power fold mechanism by the boom that will rise and fall, thus the alighting gear realizing unmanned plane is collapsible, in addition, the two groups of screw propellers being located at tail are connected with fuselage by a rotatable transverse axis, and adopt motor to provide power for rotatable transverse axis rotates, control setup, by controlling motor, is in horizontal or vertical direction to adjust the two groups of screw propellers being located at tail; Thus realizing unmanned plane at ground run, this unmanned plane structure is simple, and applicability is wide, easy to operate.
This is only the preferred embodiment of this invention above, not in order to limit the present invention, within the spirit and principles in the present invention all, and any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
