The specific embodiment:
Therefore the following stated only for embodying the preferred embodiment of the utility model principle, does not limit protection domain of the present utility model.
See shown in accompanying drawing 1 and the accompanying drawing 2, first embodiment of the present utility model provides a kind of flight whirligig 5, this flight whirligig 5 comprises a single main moving blade 12, this main moving blade 12 is rotationally connected with the main body of being made by light material 10, and the rotation direction of main body 10 is opposite with the direction of main moving blade 12.Main body 10 includes a centre mount 14 again, is placed with in the centre mount 14 to drive and control device.Centre mount 14 is made of upper and lower pedestal 18 and 16, and wherein, upper pedestal 18 and lower base 16 all connect together with an inner base frame 20.Main body 10 of the present utility model also comprises a plurality of paddles 22 that stretch out and extend to outer shroud 24 from centre mount 14 outside belows.Be provided with a motor apparatus 26 that is used to drive main moving blade 12 in the lower body seat 16, then be provided with a supply unit 28 and a circuit board 30 in the upper pedestal 18 at least.The top of upper pedestal 18 also is provided with a transparent top cover 32 and is arranged on the parts in the centre mount 14 and receives wireless signal with protection.
See shown in the accompanying drawing 3: described motor apparatus 26 is one to comprise the planetary gear reduction box 34 of motor 36, and this planetary gear reduction box 34 allows motor apparatus 26 to install along an axis that aligns with the central axis 38 of moving blade 12.
When main moving blade 12 rotates, do not need to offset the torque that main moving blade 12 produces, on the contrary, this torque can impel main body 10 backward rotation.After toy flew up, outer shroud 24 can be protected main moving blade 12 and play similar gyrostabilization effect.As mentioned above, outer shroud 24 links to each other by a plurality of paddles 22 with centre mount 14, and the surface of paddle 22 is the rising shape, can produce lift when toy 5 rotations.The direction of paddle 22 rotations is opposite with the direction of main moving blade 12, but the both provides lift can for equally toy 5, paddle 22 is defined as reverse rotation rise surface (correlation between paddle 22 and the main moving blade 12 in accompanying drawing 4 as can be seen) thus, and therefore main moving blade 12 and the characteristic relation between the paddle 22 that draws also can be adjusted so that suitable main body rotary speed to be provided.
Be positioned at the toy center of gravity (CG sees shown in the accompanying drawing 3) at rising center) the position very crucial for the self-stabilization effect.Test shows that the self-stabilization effect depends on the relative size of air damping and several power noted earlier.This just determined when CG in height apart from the bottom 24b of outer shroud 24 be equivalent to main tumbler 12 diameters 1/2～1/3 the time, the self-stabilization effect of toy is preferable, and when this distance be equivalent to main moving blade 12 radiuses 65% the time, the self-stabilization effect of toy reaches better state (it should be noted: the diameter of main moving blade 12 equates with the length sum of two paddles 22, and the length sum of so-called two paddles 22 is meant the length from the end of a paddle to the end of another paddle).It should be noted in addition: the height mutual restriction of the cross sectional shape of outer shroud 24 and CG is very important for toy 5 stable.If the CG position is too high, it is unstable that toy 5 will become, and same, the CG position is low excessively, and it is unstable that toy 5 also will become.In case and toy 5 loss of stability, the self-stabilization effect is not just known where to begin yet, this that is to say: it will be in the shape of a spiral fly out control range and produce increasing vibration of shape at flight course.
Because CG is equivalent to 65% o'clock of radius of main moving blade 12 approximately at distance outer shroud 24 bottom 24b, self-stabilization effect the best of toy, therefore, most parts are set at main body 10 tops.Therefore motor 36 must drive main moving blade 12 by long rotating shaft.In addition, because the weight of toy 5 will have influence on the position of center of gravity, therefore, main body 10 and paddle 22 all preferably use light material.
Because the paddle 22 main air damping that produces, make whirligig 5 of the present utility model quite stable when flying.As mentioned above, whole paddle 22 is streamlined and outwards extends to outer shroud 24 in the below from centre mount 14, particularly it has the angle of declination (this inclination angle can be measured by drawing an imaginary line by streamlined paddle 22 centers) of 20-30 degree, make paddle 22 have bigger area in the side, can produce bigger resistance to air, thereby prevent that whirligig 5 is amesiality when action.
Whirligig 5 is in course of action, 12 rotations of main moving blade and by the paddles 22 in the outer shroud 24 with the top guiding below of air-flow from toy 5, therefore, air-flow should flow through paddle 22 earlier when contacting with main moving blade 12, this also just means, air-flow is to be certain oblique angle and to obtain certain acceleration when paddle 22 leaves, and opposite with the situation of main moving blade 12 in static air-flow is that it must make air-flow quicken from the contiguous zone of a field flow orientation.Therefore, the efficient of main moving blade 12 improves therefrom.In addition, if paddle 22 is not mounted in main tumbler 12 tops, the summit of then main moving blade 12 tops must reduce many.
In various tests, main moving blade 12 and main body 10 are rotated with the speed of 600r/min respectively and jointly, and the lift that is produced of main moving blade 12 and main body 10 can be measured.When main moving blade 12 and main body 10 are rotated respectively, 60% of the lift that the lift that main moving blade 12 produces is produced when only being main moving blade 12 and main body 10 (together with paddle 22 interior) co-rotation.Yet, if paddle 22 has produced other 40% lift is incorrect, only produces the 5-10% of the lift that produces when being equivalent to main moving blade 12 and paddle 22 common rotations when reaching such rotating speed by independent rotation because it is found that paddle 22.Yet, produce 60% lift since say main moving blade 12, and paddle 22 only producing the lift of 5-10%, that comes can't illustrate wherefrom with regard to the lift that also has 30-35%.In fact, when main moving blade 12 separately during rotation, air-flow be do not quicken static in other words conj.or perhaps.The 5-10% of the lift that produces when equally, the paddle 22 that is installed in main moving blade 12 tops also only produces when rotation separately and is equivalent to both and rotates jointly.Can reach a conclusion thus, the existence of paddle 22 can make air-flow obtain acceleration before touching main moving blade 12, therefore, is main moving blade 12 and paddle 22 co-rotation and the air-flow that coordinate to utilize quickens and produced the lift of other 30-35%.
In another embodiment, the utility model uses biased gear reduction box 60 (seeing shown in the accompanying drawing 5), and the motor 36 of this biased gear reduction box 60 is installed to depart from the mode of central axis one side of main moving blade 12.Under the state that this biasing is installed, the gravity (not shown) that motor 36 is produced will be added on the outer shroud 24 to keep the poised state at whirligig 5 centers.
In order to control motor apparatus 26, be equipped with in the top cover 32 sensation of frequency should or receiver 40, this sensation of frequency should or receiver 40 cooperate with outside frequency emitter 52, frequency emitter 52 is installed in the remote control 50 (seeing shown in the accompanying drawing 6), remote control 50 has a trigger-like switch 54, by cocking shape switch 54, remote control 50 can be launched remote signal.In fact, except said frequencies control mode (RF), also can adopt infrared ray control mode (IR) or other control mode.In addition, though whirligig 5 under situation about being promoted by air-flow, its self-stabilization performance also can make toy 5 keep stable, air-flow can make toy 5 obtain initial motions, but final toy 5 will or stable level position of spiraling.See shown in the accompanying drawing 7: also can install one on the remote control 50 can be by the fan 56 of user's startup, and by a kind of so simple method, after fan 56 started, the air-flow that it produced can make toy 5 fly around the user.
In another one embodiment of the present utility model, see shown in accompanying drawing 8 and the accompanying drawing 9: a battery pack 80 is used to the gravity of balance offset motor 36, as shown in FIG.: the mutual balance of gravity that gravity that the motor 36 of words that this battery pack 80 is so arranged in can motor apparatus 26 produced and battery pack 80 are produced, so that whirligig 5 keeps balance, in addition, in the present embodiment, upper pedestal 18 and lower base 16 are combined into one, an ON/OFF 82 is installed in circuit board 30, and can allow the user stir by the hole 84 of top cover 32 tops.
