Miniature Finger Gyro Boomerang

Abstract

The present invention relates to a miniature finger gyro boomerang, comprising a main body casing, a propeller being arranged in the main body casing, and a shaft being arranged in the center of the propeller. Both ends of the shaft are penetrated with a finger pressing top bracket and a finger pressing bottom bracket, and the finger pressing top bracket and the finger pressing bottom bracket are respectively disposed on the top and the bottom sides of the main body casing. A drive component, a main control board and a power supply are provided in the main body casing, the power supply is electrically connected to the main control board, the main control board is electrically connected to the drive component, a motor cover of the drive component is linked with the main body casing, and the driving motor shaft is drivingly connected to the propeller. The miniature finger gyro boomerang can be used as an ordinary electric finger gyro or as a small aircraft, can be played diversely, solves the problem of the single game play of the traditional fingertip gyro or aircraft, and is beneficial to promotion.

What is claimed is: 
     
         1 . A miniature finger gyro boomerang, comprising a main body casing, a propeller being arranged in the main body casing, and a shaft is provided in the center of the propeller, characterized in that: both ends of the shaft are penetrated with a finger pressing top bracket and a finger pressing bottom bracket, the finger pressing top bracket and the finger pressing bottom bracket are respectively arranged on the top and bottom sides of the main body casing, a drive component, a main control board and a power supply are provided in the main body casing, the power supply is electrically connected to the main control board, the main control board is electrically connected to the drive component, the drive component is linked with the main body casing, and the driving motor shaft is drivingly connected with the propeller. 
     
     
         2 . The miniature finger gyro boomerang according to  claim 1 , wherein the drive component comprises a motor, a motor gear connected to a motor shaft, and a transmission gear matched with the motor gear, the upper part of the main body casing is provided with a motor house, the main control board, the power supply and the drive component are all disposed in the motor house, and a motor cover which covers the motor housing is further included. 
     
     
         3 . The miniature finger gyro boomerang according to  claim 1 , wherein the finger pressing top bracket, the finger pressing bottom bracket, the top side of the main body casing, the bottom side of the main body casing, and the propeller are assembled on the same shaft, and rotate about the shaft as a circle center during operation. 
     
     
         4 . The miniature finger gyro boomerang according to  claim 1 , wherein the longitudinal main skeleton of the main body casing is made into a propeller shape. 
     
     
         5 . The miniature finger gyro boomerang according to  claim 4 , wherein the propeller shape made by the longitudinal main skeleton of the main body casing is opposite to the propeller direction. 
     
     
         6 . The miniature finger gyro boomerang according to  claim 1 , wherein the main control board is disposed on the top side of the main body casing, and the main control board integrates an MCU main control chip, a gyroscope, and an air pressure sensor. 
     
     
         7 . A method for controlling the flight trajectory of a miniature finger gyro boomerang, the power supply is turned on, the main body casing is rotated, the MCU detects the angular velocity change signal sent by the gyroscope sensor, and the MCU sends a command to start the boomerang; the main body casing and the propeller rotate opposite to each other, generating wind in the same direction as the flying power of the boomerang, and at the same time, the gyro effect generated when the main body casing rotates at high speed keeps the boomerang balanced at an angle; when the boomerang is thrown at a certain angle, the boomerang first flies a distance in the direction of the throw under the effect of external force; after the throwing external force disappears, the angle of the boomerang remains unchanged due to the gyro effect of the high-speed rotation of the main body casing, and the boomerang continues to fly in the direction of this angle; that is, the operator can set the angle of the boomerang in advance to get different flight trajectories; during the flight, the MCU will automatically adjust the speed of the aircraft to maintain the stability of the flight by detecting the values of the gyroscope and the air pressure sensor; when the main body of the boomerang is impacted, the angular velocity changes, and the MCU sends a stop signal when detecting the relevant signal.
