As the further improvement of technique scheme, described main screw device comprises a pair of two coaxial screws that arrange straight up.
As the further improvement of technique scheme, preferred described left-hand airscrew and described right-hand screw oar arrange straight up, and can certainly adopt straight up, outward-dipping 45 degree upwards arrange etc. is symmetrical set.
As the further improvement of technique scheme, described left-hand airscrew and described right-hand screw oar include blade and drive the CD-ROM drive motor assembly of blade, the direction and the rotating speed that rotate by control circuit board control left-hand airscrew and right-hand screw oar, realize forward backward or left and right horizontal flight.
As the further improvement of technique scheme, the afterbody central authorities of described body (100) are also provided with a screw.
The beneficial effects of the utility model are: empennage twin screw remote-control toy helicopter of the present utility model comprises body, main screw device and tail undercarriage device, described tail undercarriage device comprises left-hand airscrew and right-hand screw oar, described left-hand airscrew and described right-hand screw oar are arranged on the afterbody of described body in symmetrical mode, thus, not only can provide the power of direction sidepiece to the left and right to grasp direction by left-hand airscrew and right-hand screw oar, turn freely and left and right horizontal flight, can also move forward and backward more rapidly.
Accompanying drawing explanation
Fig. 1 is according to the schematic diagram of the empennage twin screw remote-control toy helicopter of a specific embodiment of the present utility model.
Fig. 2 is the cut-away illustration of the empennage twin screw remote-control toy helicopter of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further detailed.
As depicted in figs. 1 and 2, the empennage twin screw remote-control toy helicopter 1000 of the present embodiment comprises body 100, power supply, control circuit board 110, main screw device 200 and tail undercarriage device 300.Power supply and control circuit board 110 are arranged in described body 100, and power supply is for powering to empennage twin screw remote-control toy helicopter 1000.Described main screw device 200 and described tail undercarriage device 300 are electrically connected with described control circuit board 110.Wherein, described tail undercarriage device 300 comprises left-hand airscrew 320 and right-hand screw oar 310.Described left-hand airscrew 320 and described right-hand screw oar 310 are arranged on the afterbody of described body 100 in symmetrical mode.Preferably, described left-hand airscrew 320 and described right-hand screw oar 310 symmetries are arranged on the afterbody of described body 100 straight up.And in the present embodiment, described left-hand airscrew 320 is identical with described right-hand screw oar 310 structures.
Main screw device 200 has a pair of two coaxial upper screw 210, lower screw 220, revolute axes configuration 230 and driving mechanisms 240 that arrange straight up.Driving mechanism 240 comprises CD-ROM drive motor, gear reduction etc.The power of driving mechanism 240 passes to upper screw 210 and lower screw 220 through revolute axes configuration 230, and differential or the constant speed rotation controlled between interior coaxial two screws 210,220 of main screw device 200 by control circuit board 110 realize left and right turn and flight up and down.As shown in Figure 2, described left-hand airscrew 320 and described right-hand screw oar 310 include the CD-ROM drive motor assembly 304 of blade 302 and driving blade 302.Described left-hand airscrew 320 and described right-hand screw oar 310 are controlled it by described control circuit board 110 and are turned to and rotating speed.Certainly, also can as required, by described control circuit board 110, described left-hand airscrew 320 and described right-hand screw oar 310 be controlled to blade switched in opposite.CD-ROM drive motor assembly 304 can comprise CD-ROM drive motor and/or reducing gear etc.In addition, driving mechanism 240 and CD-ROM drive motor assembly 304 are by hand-held remote controller (not shown) remote control control.
In the empennage twin screw remote-control toy helicopter 1000 of the present embodiment, control by control circuit board 110 left-hand airscrew 320, right-hand screw oar 310 CD-ROM drive motor rotating speed and turn to, for example: when left-hand airscrew 320, right-hand screw oar 310 are in the same way when forward, lifting afterbody, flies forward whole remote-control toy helicopter; When left-hand airscrew 320, right-hand screw oar 310 reverse in the same way, force down afterbody, whole remote-control toy helicopter is flown backward; When left-hand airscrew 320, right-hand screw oar 310 rotate backward, make body lopsidedness to the left or to the right, thereby make whole remote-control toy helicopter towards left and right sides horizontal flight.Twin screw on afterbody can make whole remote-control toy helicopter turn freely and left and right horizontal flight like this, increase the interest of playing, but also can utilize left-hand airscrew 320 and right-hand screw oar 310 that empennage twin screw remote-control toy helicopter 1000 is moved forward and backward more rapidly.
The above specific embodiment has been described in detail the utility model, but these not form restriction of the present utility model.Protection domain of the present utility model is not limited with above-mentioned embodiment, as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of recording in claims.
