Description

A kind of easy tilting rotor wing unmanned aerial vehicle reclining device mechanism

Technical field

The utility model relates to a kind of structure-design techniques, have devised a kind of constructional device, specifically a kind of control The system wing unmanned plane that verts verts the constructional device that the wing verts.

Background technique

Unmanned helicopter can not be limited with VTOL by place, but cruise duration and speed are relatively limited.It is fixed Wing unmanned plane length in cruise duration, speed is high but needs takeoff runway.Then from last century, technical staff finds between A kind of integrated technology that can integrate the two advantage, then tilting rotor wing unmanned aerial vehicle technology is come into being.Tilting rotor wing unmanned aerial vehicle The characteristics of the advantages of combining helicopter machine and fixed-wing, this unmanned plane has both vertical/short take-off and landing and high-performance cruise, but It is that, since tilting rotor technical pattern is complicated, control technology difficulty is big, while the wing that verts reaches designated position verting, motor Stop working hypsokinesis rotor vulnerable to aerodynamic effect occur it is uncontrollable it is irregular vert, therefore now various countries rotation of verting Wing unmanned air vehicle technique is still in infancy, only a few countries technology relative maturity.

Summary of the invention

The purpose of this utility model is for existing tilting rotor apparatus structure complexity, and control difficulty is big, designs a kind of energy Enough realize that tilt rotor aircraft stablizes the easy constructional device to vert.

The technical solution of the utility model is: a kind of easy tilting rotor wing unmanned aerial vehicle reclining device mechanism, mainly by sliding Moving axis bearing apparatus, worm gear device, fixed-wing and the wing that verts composition, the plain bearing arrangement is by sliding bearing and the bar that verts Composition, the sliding bearing are mounted on the verting in bar of worm gear device two sides, and worm gear device is by worm gear, worm screw and riveting Nail composition, worm gear are mounted on verting on bar on worm gear by rivet, drive wing rotation of verting, worm gear end connecting worm, snail Worm and gear device is placed near body nodal point, provides power by motor, and the bar that verts runs through fuselage and fixed-wing, is fixedly arranged at and is verted On rib plate, runs through and the position that consolidates is located at the aerodynamic center of wing, bar rotation of verting, sliding axle are directly driven by worm gear The both ends held are flushed with the both ends of fixed-wing, are mounted on inside fixed-wing, and the bar that verts is mounted on sliding bearing.

The simple structure of the worm gear device, the bar that verts being mounted on worm gear drive wing rotation of verting.Due to snail Worm and gear device has self-locking effect, so that the wing that verts self will not vert in motor stalls.

The bar that verts is mounted in the sliding bearing in fixed-wing, is not contacted directly with fuselage and fixed-wing generation.

The utility model has the beneficial effects that 1. the utility model structures are simple, and it is easy to assembly, it can widely be adopted With；2. the utility model controls verting for tilting rotor by worm and gear, worm and gear has self-locking effect, can effectively prevent The wing that only verts stops working the generation of phenomenon of verting because of aerodynamic effect in motor；3. used by the utility model Stock is placed on the sliding bearing in fixed-wing, is greatly reduced frictional resistance of the wing when verting that verts.

Detailed description of the invention

Fig. 1 is the main view of the utility model.

Fig. 2 is the side view of the utility model.

Fig. 3 is the top view of the utility model.

Fig. 4 is the plain bearing arrangement structural profile illustration of the utility model.

Wherein: 1. plain bearing arrangements, 1-1. sliding bearing, 1-2. vert bar, 2. worm gear devices, 2-1. worm gear, 2-2. worm screw, 2-3. rivet, 3. fixed-wings, 4. are verted the wing.

Specific embodiment

The utility model is further described with reference to the accompanying drawings and examples.

As shown in Figure 1, Figure 2, Fig. 3, a kind of easy tilting rotor wing unmanned aerial vehicle reclining device mechanism, mainly by plain bearing arrangement 1, worm and gear 2-2 device 2, fixed-wing 3 and the wing 4 that verts composition, the plain bearing arrangement 1 is by sliding bearing 1-1 and verts Bar 1-2 composition, the sliding bearing 1-1 are mounted on the verting in bar 1-2 of 2 two sides of worm and gear 2-2 device, worm and gear 2-2 Device 2 is made of worm gear 2-1, worm screw 2-2 and rivet 2-3, and worm gear 2-1 is fixed on fuselage by rivet 2-3, worm gear end Connecting worm 2-2, worm and gear 2-2 device 2 is placed near body nodal point, provides power by motor, and the bar 1-2 that verts runs through machine Body and fixed-wing 3 are fixedly arranged at and vert on 4 floor of the wing, run through and the position that consolidates is located at the aerodynamic center of wing, by worm gear 2- 1 directly drives bar 1-2 rotation of verting, and the both ends of sliding bearing 1-1 flush with the both ends of fixed-wing 3, are mounted in fixed-wing 3 Portion, the bar 1-2 that verts are mounted on sliding bearing 1-1.

The simple structure of the worm and gear 2-2 device 2, the bar 1-2 that verts being mounted on worm gear 2-1 drive the wing 4 that verts Rotation.Since worm and gear 2-2 device 2 has self-locking effect, so that the wing 4 that verts self will not occur in motor stalls It verts.

In the sliding bearing 1-1 that the bar 1-2 that verts is mounted in fixed-wing 3, do not occur directly with fuselage and fixed-wing 3 Contact.

The parts not involved in the utility model is the same as those in the prior art or can be realized by using the prior art.
