Abstract

The utility model discloses an electrical self-walking ball, which can roll on the ground without being pushed by an external force. A driver can operate the rolling of the ball by sitting up in the ball or using a remote control. The ball is composed of a ball shell, an inner ring, a middle ring, a seat frame, a shaft, an electric machine device, an accumulator, an operating device, etc. The principle and the structure of the utility model are similar to a gyroscope. Because the centre of gravity of the electrical self-walking ball is lower than the position of the centre of the ball, the ball shell and the middle ring, the middle ring and the inner ring, and the inner ring and the seat frame can rotate around a same axial cord. The three axial cords are pairwise vertical. The utility model is suitable for amusement parks and other places, and the driver's intelligence, agility, and judgment can be trained. The electrical self-walking ball also brings infinite fun to the driver.

Description

Electrical salf-walking ball

The utility model proposes the spherical device of a kind of people of taking advantage of or remote control, FYA, contest or other purposes---electronic ball voluntarily.

Ball has been on record as toy and sports apparatus.The playing method of ball is nothing but to make its motion or change the position by certain rule, promptly must apply certain active force to it, can only play in the outside of ball.

The purpose of this utility model is at above-mentioned problem, proposes a kind of electronic ball voluntarily, and it need not apply external force, and the driver can sit up straight the inside at ball, by the rolling of action button (or alternate manner) manipulation ball, the rolling of also remote-controlled commander's ball.

Technical solution of the present utility model: a transparent or latticed global shell of being made by light-weight high-strength material to be opened/closed is arranged, a pair of axle bed is arranged at one diameter two ends; 2, ring and two rings of middle ring in the spherical shell the inside has respectively have a pair of axle bed on two orthogonal diameters of ring; 3, the inside of ball is a seat frame, seat frame a pair of axle bed arranged up and down, seat, battery and control system etc. are housed on the frame, and after taking advantage of the people, the center of gravity of whole seat frame is positioned on the axial line of axle bed up and down and is lower than the mid point (being sphere center position) of axial line; 4, connect at the axle bed place by two concentric rollings or the minor axis that is slidingly matched between spherical shell and middle ring, middle ring and interior ring, interior ring and the seat, motor and contact ring, brush etc. are housed in the connection place; 5, the seat frame center of gravity is lower than sphere center position.The torque that produces therefrom when seat frame has slightly can make between global shell and middle ring, middle ring and interior ring, interior ring and the seat frame and produce relative rotation, thereby makes seat frame recover upright stable state, or drive ball is rolled.

Accompanying drawing 2 is the utility model schematic diagram.

Structure of the present utility model, principle are similar to gyroscope.Wherein 1 be global shell, it and hemisphere door 2 constitute the integral body that certain bearing capacity is arranged, and are equivalent to gyrostatic mounting, it makes transparent or latticed spheroid by light-weight high-strength material; The 2nd, hemisphere door to be opened/closed, material, shape are identical with global shell, about 1.6 meters～2 meters of the diameter adult usefulness of whole spheroid, children use about 1.2 meters～1.6 meters; The 3rd, interior ring; The 4th, middle ring, interior ring and middle ring are equivalent to two rings in the top instrument, and they are manufactured by light-weight high-strength material, and middle ring diameter is slightly less than global shell, and interior ring diameter is slightly less than middle ring; The 5th, action button; Can control three motors forward and backward or stop respectively or simultaneously; The 6th, button box; The 7th, axle.Have three to (6), cooperate by sliding or rolling at the axle bed place, respectively seat frame and interior ring, interior ring and middle ring, middle ring and global shell are bound up, four all can rotate around the axis, each to motor is installed on one in the axle bed, another then is equipped with contact ring, brush etc.; The 8th, electrical equipment control and accumulator box; The 9th, seat cushion; The 10th, seat frame, it is equivalent to the spiral shell spiral shell, different is, and gyro leans at a high speed that rotation keeps steady state, seat frame then keeps stablizing erectility by gravity, its center of gravity is lower than sphere center position, and should weigh as far as possible, low as much as possible.Can add counterweight 11 in addition is back cushions.

Accompanying drawing 1 is the force analysis schematic diagram:

Because the center of gravity of (having taken behind the driver) is on the axial line up and down of seat frame on the seat frame, position of centre of gravity is significantly less than axial line mid point (being the centre of sphere), so when taking place to roll as ball for a certain reason, make the vertical center line of deviation of gravity center ball, form a small angle theta, then gravity produces a moment of torsion WS, force between global shell, middle ring, interior ring and the seat frame and relatively rotate, thereby make seat frame and occupant's homing, remain basicly stable location status and can overturning.(three the motor on the axis can start together when starting electric machine, also can start separately, but three equal forward and backwards of motor), spherical shell, middle ring, interior ring also make the vertical center line of deviation of gravity center ball produce moment of torsion WS with relative resultant motion between the seat frame, this moment of torsion certainly leads to reaction torque balance and make ball roll with it, the principle that Here it is ball can " voluntarily ".

" electrical salf-walking ball " that the utility model proposes is applicable to that recreation ground, club, school, kindergarten etc. locate the usefulness for people's amusement, contest. Because the direction that ball rolls and driver's faces direction must be determined by three resultant motions that turn to, again because electric machine is generally uniform rotation, so any point on the sphere is uncertain with respect to the direction of motion and the speed of the centre of sphere, be that ball can produce suddenly fast suddenly slow suddenly left, suddenly right phenomenon in rolling, therefore will drive " voluntarily ball " arrival one fixed target is difficult for, arriving a moving target bumps against more difficult such as going with another ball consciously, so drive quick-witted agility and judgment that " electrical salf-walking ball " can temper the people, and bring infinite entertaining to the driver.

Claims

1, spherical device, particularly a kind of electronic ball voluntarily of taking advantage of people or remote control, FYA, contest or other purposes, it is characterized by: 1, a transparent or latticed global shell of being made by light-weight high-strength material to be opened/closed is arranged, a pair of axle bed is arranged at one diameter two ends; 2, ring and two rings of middle ring in the spherical shell the inside has respectively have a pair of axle bed on two orthogonal diameters of ring; 3, the inside of ball is a seat frame, seat frame a pair of axle bed arranged up and down, seat, battery and control system etc. are housed on the frame, and after taking advantage of the people, the center of gravity of whole seat frame is positioned on the axial line of axle bed up and down and is lower than the mid point (being sphere center position) of axial line; 4, connect at the axle bed place by two concentric rollings or the minor axis that is slidingly matched between spherical shell and middle ring, middle ring and interior ring, interior ring and the seat, motor and contact ring, brush etc. are housed in the connection place; 5, the seat frame center of gravity is lower than sphere center position, the moment of torsion that produces therefrom when seat frame has slightly can make between global shell and middle ring, middle ring and interior ring, interior ring and the seat frame and produce relative rotation, thereby make seat frame recover upright stable state, or drive ball is rolled.
