Description

Wing-Flying Vehicle Driving Mechanism {DRIVING MECHANISM OF ORNITHOPTER}

The present invention relates to a wing wing vehicle driving mechanism, and particularly, to increase the flying efficiency by adjusting the gear ratio to have the wing speed and force required for the aircraft to fly the motor power, wing wing that can be smoothly operated power transmission unit delivered to the wing It relates to a vehicle drive mechanism.

Recently, the US sells remote control (RC) winged aircraft, and the driving mechanism is not efficient due to the additional arm (ARM) between the reduction gear and connecting rod, and there is one secondary reduction gear. There is a serious disadvantage of weight imbalance. Therefore, the wing wing of the wing has a problem that the wing span is 1.5M large to enable the flight, the flight time is short about 10 minutes at a constant battery capacity. In addition, although the remote control (RC) capable of commercializing the ORNITHOPTER is commercialized, the driving mechanism is complicated. As such, the wing wing vehicle driving mechanism cannot efficiently implement the FLAPPING MOTION, so the wing area must be increased or the power must be increased to generate the same lift force as the wing wing aircraft, which is efficient. There is a short disadvantage.

As described above, the wing wing vehicle driving mechanism according to the prior art has a problem in that the wings are large and the weight is not balanced in left and right symmetry due to poor efficiency.

The present invention has been made to solve the above-mentioned problems of the prior art, and improves the flight efficiency by reducing the size of the wing to increase the flight efficiency, increase the flight time, maintain the speed to some extent to improve the flight performance The purpose is to provide.

Winged wing of the present invention for realizing the above object; A body part 40 in which the power part 10, the power transmission part 20, the servo 30, and the like are disposed; A wing part 50 and a wing structure part 60 made of a flexible material connected to the power transmission part; And it is characterized by consisting of the vertical tail wing portion 70 and the horizontal tail wing portion 80 that can adjust the direction of flight enables wing flight. The present invention relates to a driving mechanism capable of driving a wing to enable winging in the wing body, and in particular, a device for transmitting motor power to have a wing speed and force required for the aircraft to fly. The present invention relates to a remotely controlled wing vehicle driving mechanism with increased efficiency. Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

An embodiment of the remote-controlled wing aircraft according to the present invention is shown in FIG. 1; A body part 40 in which the power part 10, the power transmission part 20, the servo 30, and the like are disposed; A wing part 50 and a wing structure part 60 made of a flexible material connected to the power transmission part; And it shows a schematic structural diagram of a winged wing composed of a horizontal tail wing 70 and a vertical tail wing 80 that can adjust the flight direction.

Figure 2 is a schematic view of the power transmission portion of the main component of the wing wing aircraft according to the present invention in detail observed from the bottom wing wing body. The power transmission unit 20 is basically a device for converting a circular motion into a linear motion. In more detail, the power transmission unit may be described in detail. The first reduction gears 23 and 2 connected to the motor 21 and the motor shaft gear 22 may be described. The secondary reduction gear 24 and the secondary reduction gear 24 are composed of two pieces, one on each side so as to be connected to the left and right wings, and are connected to the wings as connecting rods (not shown) that can cause flexible vertical movement. Characterized in that configured.

3 is a perspective view seen from the front / left side of the winged vehicle drive mechanism of the present invention. In more detail, the power transmission unit 20 seen from the front / left side of the wing wing vehicle is rotated by the motor through the primary reduction gear (not shown) and the secondary reduction gear 24 connected to the motor shaft. Slow and the force turns into a powerful rotary motion. At this time, the secondary reduction gear 24 is preferably to remove a portion of the interior to reduce its own weight. A ball link is used for the connection portion 25 between the secondary reduction gear and the connecting rod, and a ball link is also used for the connecting rod connection portion 28 of the front battery zone 27 of the blade to thereby rotate the motor. The flapping movement can be smoothly changed. In addition, the ball link is also provided at the trailing edge connecting portion 29A to allow the winged aircraft to perform a smooth flapping motion. Therefore, the wing of the winged wing according to the present invention is to perform the flapping movement around the center of the flapping movement axis 29 and the trailing edge (TRAILING EDGE) connection portion 29A of the wing.

In general, a winged aircraft should not be made too large because the flapping motion increases the amplitude of the flapping movement, which affects the body itself and moves up and down. However, if the wingspan amplitude is too small, flight thrust does not occur. Therefore, the amplitude of the winged wing according to the present invention is to adjust the length of the connecting rod, so that the pitching movement of about 20 ° ~ 40 ° in the horizontal direction, about 15 ° ~ 35 ° in the downward direction. The amplitude of such a winged aircraft must be different depending on the size of the aircraft to improve flight efficiency. Therefore, the wing of the wing wing vehicle is fixed to the central portion of the flapping movement shaft 29 and rotates, and holes (not shown) are formed at various positions of the disc, which is the secondary reduction gear 24, to adjust the flapping angle of the wing. Pierced The length of the connecting rod 26 can be adjusted by the user to adjust the flapping amplitude. The power transmission unit 20 installs a ball link (BALL LINK) in consideration of this, because the friction occurs in the process of changing from the rotational movement to the vertical movement in the rotation causing power loss or the connecting rod is too much.

Figure 4 is a three-dimensional view from the front of the winged vehicle drive mechanism according to the present invention. When the power transmission unit 20 is described in more detail through a three-dimensional view of a winged vehicle from the front, the primary reduction gear 23 and the secondary reduction gear 24 connected to the motor 21 and the motor shaft, It is characterized by consisting of a connecting rod 26 is connected to the wing and induce flexible up and down movement. The wing of the wing wing flying agent according to the present invention is to perform the flapping movement around the center of the flapping movement axis 29 and the trailing edge (TRAILING EDGE) connection portion 29A through the above-described driving mechanism. In order for the winged wing driving mechanism according to this study to be successful in flight, it must be basically light, and the frequency of the number of wings moving up and down must be increased. In addition, the wing-driven vehicle driving mechanism must generate lift to overcome the weight in order for the aircraft to float, and the size of the wing must increase as the weight and power (POWER) become large. Therefore, the winged vehicle drive mechanism must ensure that the motor power has the winged speed and force at the proper gear ratio. As a preferred embodiment of the present invention, the gear reduction ratio between the motor and the wing is found to be about 85 ± 15.

FIG. 5 is a block diagram of a BALL LINK, which is a main component of a remotely controlled wing vehicle driving mechanism of the present invention. The connecting portion of the connecting rod is connected to the ball link (BALL LINK) 25A to reduce the load on the connecting rod while moving up and down.

As described above, the wing wing vehicle driving mechanism can not only reduce the size of the wing but also improve flight performance such as flight time and maneuverability.
