Description

a remote control ball

technical field

The invention relates to a remote control ball.

Background technique

In the fields of toys, teaching aids, rescue, etc., controllable motion spheres have been developed at home and abroad. In the prior art, the commonly used way to make the ball move is to install a motor inside the ball and drive the ball to realize the movement. However, the internal structure of the sphere in this driving method is complex, and most of them cannot move in any direction.

Contents of the invention

The object of the present invention is to provide a remote control small ball, which can be flexibly manipulated and can roll in any direction.

In order to achieve the above purpose, the adopted technical scheme is as follows:

The remote control ball includes a sphere, a horizontal bar, a vertical bar and a metal ball, the sphere is hollow, and includes an inner shell and an outer shell, and the spherical surface is evenly distributed between the inner shell and the outer shell. A plurality of electromagnet components, and a first power supply for supplying power to each electromagnet component and a controller for controlling the operation of each electromagnet component are arranged between the inner and outer shells, and the controller communicates with an external remote controller through a wireless method , the inner side of the inner shell is provided with a ring-shaped slideway, and the two ends of the crossbar are slidably fitted in the annular slideway, so that the crossbar can rotate in a plane passing through the center of the sphere, and the vertical The bar is vertically connected below the center of the cross bar through an elastic element, and the metal ball is fixedly installed at the lower end of the vertical bar. The upper end of the vertical rod is connected with the middle part of a connecting rod, and the two ends of the connecting rod are respectively connected with the upper horizontal rod through springs. The upper and lower ends of the inside of the sphere are respectively equipped with relative magnetic field generators. The cross bar is divided into a middle part and left and right end parts. A driving device is arranged in the middle part of the cross bar, and the driving device includes a second power supply. and a processor with a wireless receiving and transmitting module, through which the second power supply is controlled to output current to the left and right ends of the cross bar.

Further, the driving device also includes a reed and a strain gauge arranged on the middle part of the cross bar, the reed is fixed at the middle position of the cross bar, and the strain gauge is attached to the reed and connected to the processor, so The upper ends of the springs are respectively rotatably connected to the two ends of the middle section of the cross bar.

Further, the outer end of the cross bar is provided with a bearing that is in rolling fit with the annular slideway.

Further, the two ends of the connecting rod and the middle part of the cross bar are respectively fitted with rolling bearings, and the two ends of the spring are respectively connected with the outer rings of the corresponding rolling bearings.

In the present invention, the horizontal bar can freely rotate along the annular slideway in the ball, and the vertical bar installed with the metal ball can rotate around the horizontal bar in a circumferential direction. By controlling the operation of an electromagnet element in a certain part of the ball, a magnetic force is generated. The metal ball will be attracted to this part, changing the center of mass of the ball, thus making the remote control ball move. In addition, a magnetic field generating device is used to generate a magnetic field perpendicular to the rotation plane of the crossbar in the sphere, and a current is generated from the center to both ends through the driving device on the crossbar, and the crossbar is controlled in the sphere under the action of Ampere force. Rotate to match the change of the center of mass of the sphere to meet the desired direction of motion. In addition, the strain gauge and the reed are bonded to form a strain sensor, and the two springs are connected to the cross bar, so when the remote control ball stops, the reed will deform, and the controller on the ball shell controls the corresponding sensor according to the signal of the strain sensor. The short-term operation of the electromagnet element makes the remote control ball produce a tendency to move in the opposite direction, thereby reducing the defect that the remote control ball is difficult to stabilize immediately due to inertia as much as possible.

It can be seen that the remote control ball is simple in structure and flexible in action, which overcomes the problem that the existing spherical car can only move to the left or right within a radius and cannot travel in any direction, and avoids long-distance driving after turning. Driving the spherical vehicle device requires a reset process, thereby increasing the mobility of the remote-controlled spherical moving device. The remote control ball can be used as a teaching aid to show students the knowledge of electromagnetism and ampere force. In addition, the remote control ball will also be applied in various fields such as toys and rescue.
