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] The sensors used for angle detection in the prior art generally use absolute encoders. Each binary bit of this absolute encoder must occupy a ring. If it is a 3-bit binary number, plus the central power supply electrode must use 4 A ring, so the encoder structure is complicated and the volume is relatively large. If it is applied to the electronic Rubik's cube, it will definitely affect the structure and weight of the electronic Rubik's cube.
