Abstract

The invention discloses a magic cube, an incremental molded surface rotation sensor and an axis structure thereof. The incremental molded surface rotation sensor comprises a coded disc, a first electric brush and a first rotor, a first electrode, a second electrode and a third electrode are arranged on the coded disc, and all the electrodes are arranged on the first circumference of the coded discsurface; the first electric brush comprises three end points, the three end points are arranged along the first circumference, and every two end points are spaced by a radian. The first electric brush is mounted on the first rotor, drives three end points on the first rotor to rotate along a first circumference relative to the upper electrode of the first rotor through the first rotor, and is incontact with the first electrode, the second electrode and the third electrode through the three end points; the radian of the third electrode on the first circumference is shown in the specification;in the magic cube, the radians of the gap between every two electrodes, the first electrode and the second electrode on the circumference are set according to the number of pulses to be realized by the sensor; according to the magic tube, the surface rotation detection precision of the magic cube is greatly improved, and the magic cube is simpler in structure and lower in cost.

Problems solved by technology

[0003] At present, the commonly used Rubik's Cube has a single function, cannot communicate with external electronic devices, and lacks interest

In order to improve the fun of Rubik's Cube operation, some electronic Rubik's Cubes have appeared in the prior art, that is, electronic components such as sensors are arranged on the Rubik's Cube to detect the surface rotation information of the Rubik's Cube, etc., but in the prior art due to problems such as sensor volume and area It cannot be put into the inner ball in the center of the Rubik's Cube, which makes the internal structure of the Rubik's Cube more complicated

For example, the Chinese invention patent application with the publication number CN106110651A discloses a smart Rubik's Cube and its use of the induction axis structure timing method, wherein the state signal sending group for generating the state signal, that is, the sensor is arranged on the tubular shaft outside the Rubik's cube inside the inner sphere The central block, the data and electrical connection between the sensor and the inner ball are connected by a hollow tubular shaft. During the rotation of the Rubik’s Cube, the tubular shaft and the state signal sending group on it will also rotate together, which will inevitably cause the tubular shaft to rotate. The twisting of the inner circuit, after a certain period of use of the Rubik's Cube, will lead to the twisting of the inner circuit of the tubular shaft, which reduces the service life of the Rubik's Cube; Corresponding Rubik's Cube modules (including center blocks, corner blocks and edge blocks) are required, and cannot be compatible with traditional Rubik's Cube modules

[0004] In addition, in the prior art, the sensor used for angle detection in the prior art can use an incremental encoder, but the existing incremental encoder is not suitable for the Rubik's Cube at all, mainly because the installation dimensions such as volume thickness cannot reach the Rubik's Cube Requirements, the Rubik's Cube is a polyhedron, the incremental encoder is used for surface rotation detection, the use of multiple separate incremental encoders is not conducive to installation and maintenance, and the encoder used for the Rubik's Cube must adopt a single-ring design and must maintain a certain detection accuracy to ensure Detection data can be used for AI analysis of Rubik's Cube data
