Radio control helicopter toy

Abstract

The present invention provides a radio control helicopter toy including a mast mounted projecting to the upper side of an airframe so as to be rotated by a main motor, a rotor mounted on the upper part of the mast via a rotor head with the blade surface of a rotor blade capable of inclining, a blade inclining mechanism having an arm with one end part side thereof mounted rotatably on the airframe side and the other end part side thereof is mounted to be driven to approach to the above-mentioned rotor head side by an actuator, for inclining the blade surface of the above-mentioned rotor by the magnetic force generated between magnets mounted on the end part of the arm and the above-mentioned rotor head or between a magnet and a ferromagnetic material, and a receiver loaded on the above-mentioned airframe for controlling the operation of the above-mentioned main motor and the actuator.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a radio control helicopter toy, the movement control thereof is performed with remote control. [0003] 2. Description of the Related Art [0004] Conventionally, for the movement control of a helicopter, movement can be made in front and back, right and left directions by inclining the blade surface of a rotor provided on the aircraft. For inclining the blade surface of such a rotor, in the real helicopter, a mechanism for inclining the blade surface by interlocking a swash plate, rotating together with the rotor, with the blade via a link is adopted. This kind of the rotor blade surface inclining mechanism by a swash plate is adopted also for a movement control for a helicopter toy. For example, a technique related to a radio control helicopter with co-axial rotors, that is upper and lower rotor heads rotating in the opposite directions are provided concentrically, wherein the inclinin...

Benefits of technology

[0011] In the fifth aspect of the present invention, a tail pipe is mounted on the rear side of the above-mentioned airframe and a tail rotor to be driven by a tail motor is mounted on an end part of the tail pipe. With the tail rotor, the airframe turnover can be prevented as well as the airframe can be controlled in the right and left directions.

[0012] In the sixth aspect of the present invention, the magnet or the ferromagnetic material mounted on the above-mentioned rotor head of the above-mentioned blade inclining mechanism is formed in a ring-like shape surrounding the rotation center of the above-mentioned mast. Since the magnet or the ferromagnetic material mounted on the rotor head is formed in a ring-like shape, the blade surface inclination of the rotor blade can be controlled certainly.

[0013] Since a mast mounted on the upper side of an airframe so as to be rotated by a main motor loaded on the airframe, a rotor moun

Problems solved by technology

However, since the outside part is connected with an actuator mounted on the airframe for controlling the inclining of the swash plate with a link, it cannot be rotated.

Therefore, a highly sophisticated part such as a ball bearing is required for the inside and the outside
