Abstract: A smart magic cube with a ball shaft includes the ball shaft, six center blocks, eight corner blocks fitted with the center blocks, and twelve edge blocks fitted with the corner blocks and the center blocks. The center blocks are respectively arranged on a rotating shaft sensing assembly of the ball shaft. The smart magic cube with the ball shaft has a, clever design. Six printed circuit boards consist an electronic control system of the ball shaft. With each rotating shaft sensing assembly installed on each of the printed circuit boards, position sensing of the smart magic cube is accurate and a rate of lost steps of the smart magic cube is reduced. Further, the smart magic cube is not assembled by wire welding, has high integration, has a low cost, and is easy to assemble.

Abstract: A magic cube with visible magnetic cabins includes a central shaft piece, six central blocks, eight corner blocks, and twelve edge blocks. Corner block magnetic cabins and edge block magnetic cabins are respectively arranged on the corner blocks and the edge blocks. Magnets and magnetic pieces are respectively arranged in the corner block magnetic cabins and the edge block magnetic cabins. Elastic force between the central blocks and the central shaft piece is adjusted by gear adjusting pieces arranged in the central blocks. By arranging the corner block and edge block magnetic cabins, stability of installation positions of the magnets and magnetic pieces is ensured and an assembly accuracy is improved. The magnetic pieces do not fall off or offset during use. By arranging the gear adjusting pieces in the central blocks, it is convenient to quickly adjust elastic force between the central blocks and the central shaft piece.

Abstract: The present invention discloses a surface orientation sensing structure, where six printed circuit boards are combined to form a regular hexahedron as the axis of an intelligent magic cube, and a main control chipset can recognize layer rotation by simply sweeping a copper foil through a brush sheet to cause a level change, so that the position change of the layer can be recognized more accurately, a step loss rate is reduced, parts are reduced, and the assembly process is simplified. The present invention further discloses an intelligent magic cube, where all the parts related to orientation sensing are concentrated on the axis, so that the intelligent magic cube can be operated more easily and smoothly, the intelligent functions of the intelligent magic cube can be used more smoothly, and user experience is improved.

Abstract: A magnetic levitation magic cube includes edge blocks, corner blocks and center blocks. Inner sides of two side faces close to the corner blocks of the edge block each are provided with three magnet mounting grooves, and a magnet is mounted in each of the magnet mounting grooves. The center block includes a center block body and a center block cover. The center block cover covers and is spliced to the opening of the center block body. The center block further includes an upper magnetic disk and a lower magnetic disk. The upper magnetic disk is provided with a through-hole for fastening a central shaft of the magic cube. The lower magnetic disk is provided with a through-hole for the central shaft of the magic cube to pass through. Two repelling annular magnets are fixedly mounted in each of the upper magnetic disk and the lower magnetic disk.

Abstract: The present invention provides a magic cube timing device based on Bluetooth communication, including a timer main body and a non-slip mat. The timer main body is fastened to the non-slip mat. The timer main body includes a main body housing, a main control PCB board, a display apparatus, and two magnetic surface stickers. Two through holes are disposed in the main body housing. One end of the magnetic surface sticker penetrates through the through hole to connect to the main control PCB board. According to the magic cube timing device based on Bluetooth communication in the present invention, each use result in the magic cube timing device is transmitted to an external terminal by using a Bluetooth module, to effectively collect statistics on and store timing data.
