Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail. Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
As shown in Figures 1 to 4, The embodiment provides a kind of municipal administration gardens unmanned plane, including fuselage 4, empennage 5 and wing, unmanned plane can drive it to fly by the electromotor being placed in below fuselage head or wing, and described wing includes the base plate 1, wing-body 2 and the slide plate 3 that fix with described fuselage 4;
Described base plate 1 is provided with chute 11, is provided with guide pillar 12 in described chute 11, and described guide pillar 12 is provided with the first spring 13, and the medium position on described base plate 1 is provided with a screwed hole 14, and described base plate 1 is evenly equipped with multiple shallow slot 15 centered by screwed hole 14;
Described slide plate 3 top is respectively provided on two sides with a runner 31, described slide plate 3 two bottom sides is respectively equipped with a slide block 32, described slide block 32 is provided with a through hole 33, described slide block 32 is slidably mounted in described chute 11, and the through hole 33 of described slide block 32 is arranged on described guide pillar 12 so that described slide block 32 1 sidewall is resisted against described first spring 13; Being additionally provided with a postive stop baffle 16 on described base plate 1 one sidewall, described postive stop baffle 16 is for limiting the position of slide plate 3, it is prevented that slide plate 3 skids off outside the track of described chute 11 in sliding process.
On described wing-body 2, the side near fuselage 4 is provided with a connecting hole 21, described connecting hole 21 is coaxially disposed with the screwed hole 14 on described base plate 1, one screw 6 is screwed together on described screwed hole 14 and makes the relatively described base plate 1 of described wing-body 2 freely rotatable after described connecting hole 21, that is, after screw 6 is screwed together in screwed hole 14, screw 6 is positioned at the length outside screwed hole 14 and is a bit larger tham the thickness of wing-body 2 so that wing-body 2 will not be locked with base plate 1 phase by screw 6; Described wing-body 2 two side is provided with concave-arc part 22, runner 31 on described slide plate 3 is embedded in described concave-arc part 22, centered by described connecting hole 21, multiple blind hole 23 it is evenly equipped with on bottom described wing-body 2, the plurality of blind hole 23 and the plurality of shallow slot 15 one_to_one corresponding are also coaxially disposed, one second spring 24 it is provided with in each blind hole 23, the bottom contact of described second spring 24 has a spheroid 25, and described spheroid 25 part is placed in described shallow slot 15.
Described shallow slot 15 is provided with 12. Therefore described blind hole 23 is also correspondingly provided with 12. It is sticked in shallow slot 15 of course for making spheroid more accurately, it is possible to increase the quantity of shallow slot 15 and the depth of shallow slot 15 in design, specifically how to select to see actual demand.
Under original state, wing-body 2 is embedded on the first shallow slot 151 of base plate 1 by the spheroid 25 in blind hole 23, and wing-body 2 is positioned on base plate 1 by screw 6, therefore wing-body 2 and base plate 1 can keep relative static conditions, when its flight, wing-body 2 front can be subject to the counteracting force of air-flow, the outer end making wing-body 2 can have the trend towards empennage 5 motion, when this counteracting force makes spheroid 25 be sliding out the first shallow slot 151, the outer end of wing-body 2 rotates, now the concave-arc part 22 on wing-body 2 can promote runner 31, spheroid 25 on wing-body 2 can move towards the second shallow slot 152, at this moment slide plate 3 slides along chute 11, thus bestowing 12 1 thrusts of the first spring, the propulsive thrust of the first spring 12 offsets with the counteracting force of air-flow, at this moment the spheroid 25 on wing-body 2 can be embedded in the second shallow slot 152, when the flight speed of unmanned plane continues to increase, spheroid 25 on wing-body 2 can move towards the 3rd shallow slot 153, it is achieved thereby that can according to the function of flight speed auto-changing wing sweep angle.When wing-body 2 collides, wing-body 2 can transfer, with screw 6, the probability reducing damage for center of circle automatic rotary. When stopping flight, wing-body 2 can be returned to initial position by the propulsive thrust of the first spring 12, namely makes spheroid 25 be positioned on the first shallow slot 151.
As shown in Figure 5, described empennage 5 includes the first motor 51 being located in fuselage 4 rearward end and the connection ring 54 extending fuselage 4 rear end, it is connected to rotating shaft 55 by bearing in described connection ring 54, described rotating shaft 55 horizontally set, described rotating shaft 55 is fixedly connected with travelling gear 53, described first motor 51 drives described travelling gear 53 by driving gear 52, the two ends place of described rotating shaft 55 is respectively provided with one second motor 57, and the output shaft of described second motor 57 is connected to propeller 56. First motor 51 drives travelling gear 53 to rotate by driving gear 52, and travelling gear 53 is rotated axle 55 and rotates in connection ring 54, the therefore rotational angle of scalable propeller.
The present invention is compared to prior art, has the advantages that
The municipal gardens unmanned plane of the present invention can realize the different auto-changing wing sweep angle along with flight speed; when flight speed height, the sweep angle of wing becomes big, thus reducing flight resistance; promote flight efficiency, and can effectively protect when colliding wing not damaged.
The empennage of the present invention converts the rotational angle of propeller by rotating shaft, it may be achieved slows down, accelerate, assisted degradation effect.
Certainly, above is only the concrete exemplary applications of the present invention, and protection scope of the present invention is not constituted any limitation. In addition to the implementation, the present invention can also have other embodiment. All employings are equal to replacement or the technical scheme of equivalent transformation formation, all fall within present invention scope required for protection.
