Smart spindle with replaceable battery, and smart Rubik's cube

A battery-replaceable smart center shaft, comprising:

• a core;
• a conductive member;
• a battery cover;
• a sensor;
• and
• a main control module,
• wherein the core comprises a housing with a cavity, the main control module is mounted in the cavity, the sensor is electrically connected to the main control module, and the sensor is mounted at the core, and
• wherein a battery is further mounted in the cavity, the housing is provided with a notch for the battery to pass in and out, and the notch is in communication with the cavity;
• or the battery is mounted on an exterior of the housing, the housing is provided with a through hole through which the cavity is in communication with the exterior of the housing;
• wherein the conductive member is electrically connected to the battery and the main control module respectively, and the battery supplies electrical energy to the main control module via the conductive member;
• wherein a mounting position is provided in the cavity for a detachable mounting of the battery, and
• wherein the notch is located directly above the mounting position, such that the battery is capable of being vertically mounted on the mounting position through the notch;
• or the notch is located obliquely above the mounting position, such that the battery is capable of being obliquely mounted on the mounting position through the notch;
• or the notch is located on a same horizontal plane as the mounting position, such that the battery is capable of being horizontally mounted on the mounting position through the notch;
• wherein the notch is located obliquely above the mounting position, a side of the battery cover adjacent to the cavity is provided with an abutting bevel, during a process of the battery cover closing the notch, the abutting bevel abuts against the battery, such that the battery slides along the abutting bevel to the mounting position.
