The utility model is characterized in that the adjuster is at the end of the tail, therefore, the adjuster is separated from the rotation shaft of the propeller, to simplify the structure of the adjuster, reduce the production hardness and cost, and move the adjuster position from the body to the tail, to make adjustment flexible.
Description
Technical field
The utility model relates to a kind of toy helicopter, more particularly, relates to a kind of can moving forward and backward and toy helicopter simple in structure.
Background technology
Existing toy helicopter generally comprises fuselage main body, afterbody, undercarriage and screw, afterbody is fixedly connected on the rear portion of fuselage main body, undercarriage be fixedly mounted on the fuselage main body below, screw is installed on the fuselage main body by a rotating shaft, is provided with a body nodal point governor motion between above-mentioned rotating shaft and the fuselage main body.
Existing its operation principle that moves forward and backward of toy helicopter is: adjust the position of screw rotating shaft on the fuselage main body by the body nodal point governor motion, make the center of gravity occurrence positions of the whole fuselage of toy helicopter change, when the screw rotating shaft is positioned at the center of fuselage, the center of gravity of fuselage straight down, this moment, toy helicopter was in the anterior-posterior balance state, and toy helicopter can vertically rise or descend; When the position of screw rotating shaft on the fuselage main body moved backward, the center of gravity of fuselage forward, the afterbody of toy helicopter is just tilted upward, thereby toy helicopter is travelled forward; When the screw rotating shaft in the position on the fuselage main body to when reach, the center of gravity of fuselage backward, the afterbody of toy helicopter is just to pressing down, thereby toy helicopter is moved backward.Because adjust its complex structure of body nodal point governor motion of screw rotating shaft position, so the manufacture difficulty of this body nodal point governor motion and cost of manufacture height, simultaneously, this body nodal point governor motion is also dumb to the adjusting of body nodal point.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of can moving forward and backward and toy helicopter simple in structure.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of toy helicopter, comprise fuselage main body, afterbody, undercarriage, screw and body nodal point governor motion, afterbody is fixedly connected on the rear portion of fuselage main body, undercarriage be fixedly mounted on the fuselage main body below, screw is installed on the fuselage main body by a rotating shaft, it is characterized in that: the body nodal point governor motion is located on the end of afterbody.
Described body nodal point governor motion comprises a two-way motor and a fan blade, and either-rotation motor and fan blade are installed on the end of afterbody, and either-rotation motor and fan blade are in transmission connection, and fan blade and horizontal plane be arranged in parallel.
When the empennage of toy helicopter be located at afterbody below the time, described either-rotation motor is installed on the end of afterbody straight up, fan blade is directly installed in the rotating shaft of either-rotation motor, fan blade be positioned at either-rotation motor above;
When the empennage of toy helicopter be located at afterbody above the time, described either-rotation motor verticallydownwardly is installed on the end of afterbody, fan blade is directly installed in the rotating shaft of either-rotation motor, fan blade be positioned at either-rotation motor below.
Like this, when either-rotation motor drove fan blade to canyon, fan blade was subjected to the upward reaction force of air, thereby the afterbody of toy helicopter is tilted upward, make the whole fuselage of toy helicopter center of gravity forward, toy helicopter travels forward under the effect of gravity; When either-rotation motor drove fan blade to up-draught, fan blade was subjected to the downward reaction force of air, thereby the tail down of toy helicopter is pressed, make the whole fuselage of toy helicopter center of gravity backward, toy helicopter is motion backward under the effect of gravity; When either-rotation motor stops operating, the center of gravity of the whole fuselage of toy helicopter straight down, toy helicopter is in the anterior-posterior balance state, toy helicopter can vertically rise or descend.
The utility model beneficial effect against existing technologies is, because the body nodal point governor motion is located on the end of toy helicopter afterbody, thereby the body nodal point governor motion is separated with the screw rotating shaft, simplify the structure of body nodal point governor motion widely, reduced the manufacture difficulty and the cost of manufacture of body nodal point governor motion; Simultaneously, the position of body nodal point governor motion is moved on on the afterbody from the fuselage main body, make the body nodal point governor motion become more flexible the adjusting of body nodal point.
Below in conjunction with the drawings and specific embodiments the utility model is described further.

The specific embodiment
As shown in Figure 1 and Figure 2, a kind of toy helicopter, comprise fuselage main body 1, afterbody 2, undercarriage 3, screw 4 and body nodal point governor motion, afterbody 2 is fixedly connected on the rear portion of fuselage main body 1, undercarriage 3 be fixedly mounted on fuselage main body 1 below, the screw of present embodiment 4 adopts double-propeller structures, screw 4 is installed on the fuselage main body 1 by a rotating shaft 5, the fixed-site of rotating shaft 5 on fuselage main body 1, the body nodal point governor motion is located on the end of afterbody 2.
Above-mentioned body nodal point governor motion comprises a two-way motor 6 and a fan blade 7, in the present embodiment, since the empennage 8 of toy helicopter be located at afterbody 2 below, so, either-rotation motor 6 is installed on the end of afterbody 2 straight up, fan blade 7 is directly installed in the rotating shaft of either-rotation motor 6 and with horizontal plane and be arranged in parallel, fan blade 7 be positioned at either-rotation motor 6 above.
Small arrow is represented the direction of fan blade 7 blowings among Fig. 3, Fig. 4, and big arrow is represented the direction of motion of toy helicopter afterbody 2.
When playing, when either-rotation motor 6 counter-rotatings, either-rotation motor 6 drives fan blade 7 to canyon, be that fan blade 7 is when the medium and small direction of arrow of Fig. 3 is dried, fan blade 7 is subjected to the upward reaction force of air, thereby the afterbody 2 of toy helicopter is tilted upward, shown in big arrow among Fig. 3, make the whole fuselage of toy helicopter center of gravity forward, toy helicopter travels forward under the effect of gravity; When either-rotation motor 6 is just changeing, either-rotation motor 6 drives fan blade 7 to up-draught, be that fan blade 7 is when the medium and small direction of arrow of Fig. 4 is dried, fan blade 7 is subjected to the downward reaction force of air, thereby the afterbody 2 that makes toy helicopter is to pressing down, shown in big arrow among Fig. 4, make the whole fuselage of toy helicopter center of gravity backward, toy helicopter is motion backward under the effect of gravity; When either-rotation motor 6 stops operating, the center of gravity of the whole fuselage of toy helicopter straight down, toy helicopter is in the anterior-posterior balance state, toy helicopter can vertically rise or descend.
As shown in Figure 5, in embodiment 2, since the empennage 8 of toy helicopter be located at afterbody 2 above, so, either-rotation motor 6 verticallydownwardlies are installed on the end of afterbody 2, fan blade 7 is directly installed in the rotating shaft of either-rotation motor 6 and with horizontal plane and be arranged in parallel, fan blade 7 be positioned at either-rotation motor 6 below.
The utility model is not limited to the version in the foregoing description; screw 4 of the present utility model also can be the single screw structure; in a word, as long as the body nodal point governor motion of toy helicopter is located on the end of afterbody 2, all drop within the protection domain of the present utility model.
