Abstract

A chessboard includes a housing having a chessboard area, wherein the chessboard area includes a plurality of chess squares; at least one first magnetic absorbing element arranged in the housing and corresponding to the chessboard area, configured to absorb, at least one chess piece having a second magnetic absorbing element by using a magnetic force; and a plurality of Hall elements arranged in the housing and corresponding to the plurality of chess squares, wherein each Hall element is configured to detect the second magnetic absorbing element of the at least one chess piece in the chess squares, and output a detected signal; and a control module, electrically connected to the plurality of Hall elements and configured to receive the detected signal to get information on the at least one chess piece in the chess squares.

Claims19

Dependent claims

A chessboard, comprising:

a housing, having a chessboard area, wherein the chessboard area comprises a plurality of chess squares;
at least one first magnetic attractable element, arranged in the housing and corresponding to the chessboard area, configured to be attracted by a second magnetic attractable element of at least one chess piece through a magnetic force;
and
a plurality of Hall elements, arranged in the housing and corresponding to the plurality of chess squares respectively, wherein each Hall element is configured to detect the second magnetic attractable element of the at least one chess piece on the chess squares, and output a detected signal;
and
a control module, electrically connected to the plurality of Hall elements and configured to receive the detected signal to get information on the at least one chess piece on the chess squares;
wherein the housing comprises a bottom case, a front case, and a cover plate, wherein the front case is connected to the bottom case to enclose an accommodating space, the Hall elements are arranged in the accommodating space, the front case has a main area, the chessboard further comprises a plurality of light emitting elements arranged in the accommodating space and corresponding to the plurality of chess squares respectively, wherein the cover plate is a light transmitting element, the main area is light-transmitting, and light emitted by the light emitting elements is emitted out of the chessboard through the main area, hollowed-out areas of the at least one first magnetic attractable element, and the cover plate;
and the control module is arranged in the housing and is electrically connected to the light emitting elements and the Hall elements, and the control module is further configured to control on and off of the light emitting elements according to the detected signal;
wherein if there are multiple candidate chess squares that a current chess piece of the at least one chess piece on a current chess square of the plurality of chess squares can be moved on, the control module further controls the light emitting elements corresponding to the multiple candidate chess squares to emit the light in different colors and/or brightnesses, and the different colors and/or brightnesses are configured to indicate different recommended levels of moving the current chess piece.
