Description

Tail double propeller remote control toy helicopter

The invention belongs to the field of toys, and in particular relates to a remote control toy helicopter. Background technique

The remote-controlled toy helicopter is popular among children because of its ability to fly remotely in the air. However, since the current main power of the remote control toy helicopter is derived from the main propeller device installed in the middle of the fuselage, the left and right steering is realized by differential or constant speed rotation between the two propellers in the main propeller device. And flying up and down, and relying on a rear tail propeller to control the flight before and after, but can not freely turn or fly laterally, so the lack of novelty in play, the interest is not strong enough, it is difficult to meet the children's play requirements.

As a further improvement of the above technical solution, the main propeller device comprises a pair of coaxial two propellers arranged vertically upward.

As a further improvement of the above technical solution, it is preferable that the left propeller and the right propeller are vertically disposed, and of course, the left and right symmetrical arrangement may be adopted such that the vertical propeller is inclined upward by 45 degrees.

As a further improvement of the above technical solution, the left propeller and the right propeller each include a driving motor assembly of the blade and the driving blade, and the direction and the rotation speed of the left propeller and the right propeller are controlled by the control circuit board to realize the forward direction. Fly laterally or left and right. As a further improvement of the above technical solution, a propeller is disposed in the center of the tail of the body (100).

The beneficial effects of the present invention are: The empennage double propeller remote control toy helicopter of the present invention comprises a body, a main propeller device and a tail propeller device, the tail propeller device comprising a left propeller and a right propeller, the left propeller and the right The propeller is disposed at the tail of the body in a bilaterally symmetrical manner, thereby not only providing the force to the left and right side by the left propeller and the right propeller, but also grasping the direction, freely turning and laterally flying, and also being faster. Advance and retreat.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic illustration of a tail twin propeller remote control toy helicopter in accordance with an embodiment of the present invention.

2 is a cross-sectional view of the tail rotor double propeller remote control toy helicopter of FIG. detailed description

The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings.

As shown in Figs. 1 and 2, the tail twin propeller remote control toy helicopter 1000 of the present embodiment includes a body 100, a power source, a control circuit board 110, a main propeller device 200, and a tail propeller device 300. A power and control circuit board 110 is disposed within the body 100 for powering the tail twin propeller remote control toy helicopter 1000. The main propeller device 200 and the tail propeller device 300 are electrically connected to the control circuit board 110. Wherein the tail propeller device 300 includes a left propeller 320 and a right propeller 310. The left propeller 320 and the right propeller 310 are disposed at the tail of the body 100 in a bilaterally symmetrical manner. Preferably, the left propeller 320 and the right propeller 310 are symmetrically disposed vertically upward at the tail of the body 100. Moreover, in this embodiment, the left propeller 320 and the right propeller 310 have the same structure.

The main propeller device 200 has a pair of coaxially disposed two upper vertical propellers 210, a lower propeller 220, a rotating shaft structure 230, and a drive mechanism 240. The drive mechanism 240 includes a drive motor, a gear reduction mechanism, and the like. The power of the driving mechanism 240 is transmitted to the upper propeller 210 and the lower propeller 220 via the rotating shaft structure 230, and the differential or constant speed between the two propellers 210, 220 coaxial in the main propeller device 200 is controlled by the control circuit board 110. Rotate to achieve left and right steering and flying up and down. As shown in FIG. 2, the left propeller 320 and the right propeller 310 each include a paddle 302 and a drive motor assembly 304 that drives the paddle 302. The left The propeller 320 and the right propeller 310 are controlled by the control circuit board 110 for their steering and rotational speed. Of course, the left propeller 320 and the right propeller 310 may be controlled to be opposite to the blade turning by the control circuit board 110 as needed. Drive motor assembly 304 can include a drive motor and/or a speed reduction mechanism or the like. Additionally, drive mechanism 240 and drive motor assembly 304 are remotely controlled by a hand held remote control (not shown).

In the empennage double propeller remote control toy helicopter 1000 of the present embodiment, the rotational speed and steering of the driving motors of the left propeller 320 and the right propeller 310 are controlled by the control circuit board 110, for example: when the left propeller 320 and the right propeller 310 are in the same direction When turning forward, lift the tail to make the whole remote toy helicopter fly forward; when the left propeller 320 and the right propeller 310 reverse in the same direction, lower the tail to make the whole remote toy helicopter fly backward; left propeller 320, right When the propeller 310 is rotated in the reverse direction, the body is tilted to the left or right side, so that the entire remote control toy helicopter flies laterally to the left and right sides. The double-spiral slurry on the tail can make the whole remote-controlled toy helicopter freely turn and laterally fly, which increases the fun of play, and can also use the left propeller 320 and the right propeller 310 to make the tail double-propeller remote control toy straight. The aircraft 1000 advances and retreats more quickly.

The present invention has been described in detail in the above embodiments, but these are not intended to limit the invention. The scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the present invention are included in the scope of the claims.
