Abstract

A chessboard toy is provided. A first driving coil is arranged on an inner ring of a knob, and a second driving coil is arranged on a rotating member; and the first driving coil and the second driving coil mesh with each other, so that a rotation sensing member can be controlled by direct mechanical transmission; mechanical motion of the knob can be converted into an electrical signal of the rotation sensing member; and use of a light sensing mechanism or a magnetic sensing mechanism is avoided. Therefore, structural complexity and a fault rate are reduced. In addition, compared with the light sensing mechanism and the magnetic sensing mechanism that have high costs, a technical solution can also significantly reduce production and manufacturing costs.

Description

TECHNICAL FIELD The present disclosure relates to the field of toys, and in particular, to a chessboard toy. BACKGROUND Chessboard type electronic toys or educational equipment (such as electronic chess, Go, and logic training boards) often require users to select specific positions on a chessboard for operation. At present, a mainstream interaction manner for position selection mainly adopts a knob: The knob style scheme is usually to control a cursor to move through a rotation component or a knob like component sleeved outside an equipment housing. A user can rotate the knob to change a selected position. However, in order to accurately convert a manual rotation action of the user into an equipment-recognizable electrical signal (such as a coordinate change) and achieve smooth movement of the cursor on a two-dimensional chessboard, this scheme often forms a recognizable electrical signal through a light sensing mechanism or a magnetic sensing mechanism. This directly leads to structural complexity of a product and further increases a fault rate.
