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.
Claims10
A chessboard toy, comprising:
- a housing;
- a knob rotatably arranged on the housing, wherein an outer ring of the knob is exposed out of the housing;
- an inner ring of the knob is provided with a first driving coil and is exposed inside the housing;
- and
- a sensing feedback device comprising a circuit board, a rotation sensing member, a rotation member, and a screen display assembly, wherein the circuit board is arranged inside the housing;
- the rotation sensing member is arranged inside the housing and is electrically connected to the circuit board;
- the rotation member is rotatably connected to an input end of the rotation sensing member;
- the rotation member is provided with a second driving coil which meshes with the first driving coil;
- the screen display assembly is electrically connected to the circuit board and is exposed out of the housing;
- and
- when the knob is rotated, the first driving coil drives the second driving coil to rotate, so that the second driving coil drives the rotation member to rotate, and then the rotation sensing member outputs an electrical signal to the circuit board through the rotation member.
