Embodiment
With reference to the accompanying drawings and examples, the embodiment of the present invention is described in further detail.Following reality Apply example to be used to illustrate the present invention, but be not limited to the scope of the present invention.
As shown in Figures 1 to 4, the embodiment provides a kind of energy-conserving and environment-protective architectural engineering with folding wings nobody Machine, including fuselage 4, empennage 50 and wing, the wing are connected by fold mechanism with fuselage 4, and the wing includes bottom plate 1st, wing-body 2 and slide plate 3;
The top of bottom plate 1 is provided with chute 11, is provided with guide pillar 12 in the chute 11, first is provided with the guide pillar 12 Spring 13, the medium position on the bottom plate 1 are provided with a screwed hole 14, are evenly equipped with the bottom plate 1 centered on screwed hole 14 Multiple shallow slots 15;
The top both sides of slide plate 3 are respectively equipped with a runner 31, and the two bottom sides of slide plate 3 are respectively equipped with one first sliding block 32, first sliding block 32 is provided with a through hole 33, and first sliding block 32 is slidably mounted in the chute 11, and described first slides The through hole 33 of block 32 is arranged on the guide pillar 12 so that the side wall of the first sliding block 32 1 is resisted against first spring 13;Institute State and a postive stop baffle 16 is additionally provided with the side wall of bottom plate 1 one, the postive stop baffle 16 is used for the position for limiting slide plate 3, anti-limited slip plate 3 Outside the track that the chute 11 is skidded off in sliding process.
On the wing-body 2 connecting hole 21, the connecting hole 21 and the bottom plate 1 are provided with close to the side of fuselage 4 On screwed hole 14 be coaxially disposed, a screw 6 is screwed together on the screwed hole 14 after passing through the connecting hole 21 and makes the machine Wing body 2 is freely rotated relative to the bottom plate 1, that is to say, that after screw 6 is screwed together in screwed hole 14, screwed hole is located on screw 6 Length outside 14 is slightly larger than the thickness of wing-body 2 so that screw 6 will not lock wing-body 2 and the phase of bottom plate 1;It is described Have on the two side of wing-body 2 provided with concave-arc part 22, the runner 31 on the slide plate 3 is embedded in the concave-arc part 22, the machine Be evenly equipped with multiple blind holes 23 on the bottom of wing body 2 centered on the connecting hole 21, the multiple blind hole 23 with it is the multiple shallow Groove 15 is corresponded and is coaxially disposed, and a second spring 24, the bottom top of the second spring 24 are provided with each blind hole 23 A spheroid 25 is had, the part of spheroid 25 is placed in the shallow slot 15.
The shallow slot 15 is provided with 12.Therefore the blind hole 23 is also correspondingly provided with 12.Of course for more accurately making ball Body 25 is sticked in shallow slot 15, can 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 bottom plate 1 by the spheroid 25 in blind hole 23, and Wing-body 2 is positioned on bottom plate 1 by screw 6, therefore wing-body 2 can keep relative static conditions with bottom plate 1, when it flies During row, the front of wing-body 2 can be by the reaction force of air-flow so that the outer end of wing-body 2 can have transports towards empennage 50 Dynamic trend, when the reaction force make it that spheroid 25 is sliding out the first shallow slot 151, the outer end of wing-body 2 rotates, this opportunity Concave-arc part 22 on wing body 2 can promote runner 31, and the spheroid 25 on wing-body 2 can move towards the second shallow slot 152, at this moment Slide plate 3 slides along chute 11, so as to bestow 13 1 thrusts of the first spring, the propulsive thrust of the first spring 13 and air-flow it is anti- Active force is offseted, and at this moment the spheroid 25 on wing-body 2 can be embedded in the second shallow slot 152, when the flying speed of the present invention When continuing increase, the spheroid 25 on wing-body 2 can move towards the 3rd shallow slot 153, it is achieved thereby that can be according to flying speed The function of auto-changing wing sweep angle.When wing-body 2 collides, wing-body 2 can be that center of circle automatic rotary transfers with screw 6 Reduce the possibility of damage.When stopping flight, wing-body 2 can be returned to initial position by the propulsive thrust of the first spring 13, I.e. so that spheroid 25 is located on the first shallow slot 151.
As shown in figure 5, the fold mechanism includes the sliding block 81 of slide rail 80 and second being fixed on the fuselage 4, institute Stating slide rail 80 includes the flat segments 801 at middle part and the segmental arc 802 located at flat segments both sides, is fixed in the flat segments 801 Double end cylinder 82 is installed, the segmental arcs 802 of both sides is slidably installed second sliding block 81 respectively, second sliding block 81 are rotatablely connected a jacking block 84 by rotating shaft 83, are connected in the vertical direction of the both sides output end of the double end cylinder 82 One jacking block cylinder 85, the output end of the jacking block cylinder 85 connect the jacking block 84, are also fixedly connected on second sliding block 81 The bottom plate 1 of the wing.
When needing folding or expansion wing, the output end of double end cylinder stretches to both sides or inwardly collapsed, while jacking block Cylinder is linked with double end cylinder, makes jacking block promote sliding block to be slided along slide rail, so as to drive bottom plate to be rotated.
As shown in fig. 6, the empennage 50 includes the first motor 51 in the rearward end of fuselage 4 and extends fuselage 4 The connection ring 54 of rear end, the connection ring 54 is interior to be connected with rotary shaft 55 by bearing, and the rotary shaft 55 is laterally set, described Travelling gear 53 is fixedly connected with rotary shaft 55, first motor 51 drives the travelling gear by driving gear 52 53, one second motor 57 is respectively provided with the both ends of the rotary shaft 55, and spiral is connected with the output shaft of second motor 57 Oar 56.First motor 51 drives travelling gear 53 to rotate by driving gear 52, and travelling gear 53 drives rotary shaft 55 connecting Rotated in ring 54, therefore the rotational angle of adjustable propeller.
The present invention is compared to prior art, has the advantages that:
The present invention can be achieved with the different auto-changing wing sweep angles of flying speed, when flying speed is high, wing Sweep angle becomes big, so as to reduce flight resistance, lifts flight efficiency, and can effectively protect wing not damaged when colliding;
Due to that provided with fold mechanism, folding wing can be facilitated, be easy to deposit, there is practicality;
Because empennage can convert the rotational angle of propeller by rotary shaft, so as to realize deceleration, accelerate, auxiliary landing And other effects.
Certainly, it the above is only the concrete application example of the present invention, protection scope of the present invention be not limited in any way.Remove Outside above-described embodiment, the present invention can also have other embodiment.All technical sides formed using equivalent substitution or equivalent transformation Case, all fall within scope of the present invention.
