Description

Aerobat toy
Technical field
The utility model relates to a kind of toy, relates in particular to a kind of aerobat toy of large volume.
Background technology
In recent years, the more and more new modelings of aerobat toy emerge in an endless stream, from the aircraft to the flying saucer, even various birds, insect, all kinds of various, common aerobat toy comprises body and remote controller, wherein, body comprises propeller unit, fuselage and foot rest, propeller unit is single-blade formula or two oar formula, and the single-blade formula is provided in a side of one group of screw of back, and two oar formulas are provided in a side of two groups of screws of back, be used to realize the lift-off of aircraft, screw is driven by single motor; Fuselage comprise skull, with skull the fuselage main body and the urosome on limit mutually, urosome is fixedly connected on the rear portion of fuselage main body, empennage is installed on the urosome, the balance control of assisting in flying device in flight course, to realize the balance and the assisted diversion of aircraft, the part aircraft also can realize turning to function by the screw or the transfer on top, control by the empennage auxiliary balance again, but this class formation is adapted to the less situation of aircraft volume, because the aircraft resistance of large volume is bigger, this kind design makes flight lift inefficiency, and stability is also relatively poor; And the frequent steering operation when single-motor is changed because of state of a control causes mechanical friction increase and electric energy loss, and energy consumption is increased, and causes battery life short, and motor is required height, and cost is big, and easily heating easily produces fault, reduces battery motor access times, life-span.And the frequent steering operation when single-motor is changed because of state of a control causes the control operation process of aircraft not mild, and aircraft flight is stable inadequately and straighforward operation is not smooth; And single-motor can not be realized turning left and right of fuselage or actionless controlling.And the cylinder of similar large volume, as shapes such as various ampuliforms or Other Drinks jars, the aircraft of this class is not have, and so has more sight, and the aircraft that can serve as the business marketing instrument does not have.
The utility model content
The purpose of this utility model is to overcome above deficiency, the peculiar propeller system of structure that provides a kind of screw branch to put to be arranged on the housing top and the bottom; And two independent transmission systems of reason drive and cause flying object to turn to the controlled or static aircraft that has more sight; Break through the aerobat toy of cylindrical or other shape appearance uniquenesses of the large volume of present type with housing.
In order to solve the problems of the technologies described above, to carry out the utility model and improve.The utility model provides a kind of aerobat toy, comprise screw, fuselage and undercarriage, described screw comprises first screw and second screw, and described first screw is installed in the top of fuselage, and described second screw is installed between fuselage and the below undercarriage; Described first screw and second screw do not limit the portion of saying and have only one group of blade, they can comprise the blades that two or three place up and down or be placed on conplane several blade jointly, and what meaning of the present utility model was fuselage is respectively equipped with screw up and down.
Described two screws, their turning cylinder is on same vertical curve.Their turning cylinder be up and down separate type on same vertical curve.Drive and rotate shaft drive separately independently, installation direction is opposite.Comprise two motors, described first screw is driven by first motor wherein, and second screw is driven by second motor, and direction of rotation is opposite.But described transmission device is not limited to two motors, can reach driving by single motor or Thomas.Can drive second screw by single motor, second screw is a type drive paddle, drives aircraft and rises, and first screw is done rightabout passive rotation under the effect of air-flow.Or driving first, second screw simultaneously by single motor, first screw and second screw are done rightabout rotation.
Described fuselage is cylinder, doleiform, cube, prismatic, regular body or irregular body.
Described first screw comprises contiguous block, blade and balancing pole, and described contiguous block, blade and balancing pole adopt hinge to be connected; Described second screw comprises contiguous block and blade, and blade is installed in the end of contiguous block.
Described balancing pole comprises balance mobile jib and counterweight, and counterweight is arranged on the end of balance mobile jib.
Described balancing pole adopts hinge to be connected with the contiguous block of first screw.
Described first screw is in-line monolithic or cross leaf, and second screw is in-line monolithic or cross leaf.
By bold change of flight device structure, this structure is unprecedented: above the aircraft, below screw respectively is installed, by test, find that this design makes aircraft have more stability, flight usefulness, can be handling comparatively desirable, especially bigger for body volume, air drag thereby bigger type, upper and lower Design of Propeller makes the volume that is obstructed reduce half, improve lift, this class formation more adapts to the large tracts of land aircraft.
Through repetition test, find to use coaxial double-layer propeller, because body volume is big, the resistance that is obstructed is big, lifting force is poor, and has certain friction, and usefulness is relatively poor, stability is influenced, the propeller arrangement choosing is transformed for this reason, change the same straight line in axle center into, but two therefrom separated independent rotation axles of entity, without co-axial arrangement, solve that above resistance is big, inefficiency, instability problem.
With respect to prior art, the advantage of the utility model aerobat toy is as follows,
1, adopt upper and lower Design of Propeller, make the area that is obstructed reduce half, improved the lifting force of aircraft effectively, and flight is more stable;
2, the power transmission shaft of two concentricity lines has reduced frictional force and energy loss that motor produces on coaxial when turning to, and makes and control stability and effectively improve.
3, adopt different shape fuselages such as pop can, ampuliform, break through the manifestation mode of aircraft in the past, this moulding is the brand-new moulding with tail, and suitable application area is more extensive, and makes aircraft handsome in appearance, diversified, and fuselage has more sight.
4, each attaching parts of screw mostly are hinged, and promptly screw is the active type screw, and are not yielding in the bump, effectively avoid hurting the manipulator, improve the security when playing greatly.
5, with screw about each control of double motor, body follows rotation to increase frictional force when having avoided single-motor control, and energy consumption is big.And can realize thoroughly controlling to aircraft, can be to anticlockwise, also can be to right rotation, but also transfixion, and control is more smooth, agile.
Like this, aircraft is various shapesization aloft, can adapt to various commercial uses, as advertisement etc., the variation of realization product function, developing new manifestation mode and application channel in field is a quantum jump to the bulky objects aircraft for this reason, is a kind of new creation of structural shape application.For example, housing can be designed to similar Coca-Cola, Pepsi Cola or other tank bodies, all is very unique design and moulding as propaganda and gift.
