Charging box

A charging box, comprising:

• a box body (1), internally provided with a product cabin (11), the product cabin (11) being configured to accommodate a product;
• a box cover (2), openably and closably arranged at an opening of the box body (1);
• a battery (3), arranged in the box body (1);
• a charging assembly (4), comprising a magnet pendulum bob (41) and a coil structure (42) arranged in a periphery of the magnet pendulum bob (41), wherein a first end (411) of the magnet pendulum bob is rotatably connected with the box body (1) and a second end (412) of the magnet pendulum bob is a free end;
• and
• a circuit assembly (7), electrically connected with the coil structure (42) to receive an induced current generated by the coil structure (42), the circuit assembly (7) being electrically connected with the battery (3);
• wherein the charging assembly (4) further comprises a generator (43), wherein the generator (43) is configured to convert kinetic energy generated by a motion of the magnet pendulum bob (41) into electric energy, and the generator (43) is electrically connected with the circuit assembly (7);
• the charging box further comprises a transmission part (5), the transmission part (5) being configured to transmit a motion of the magnet pendulum bob (41) to the generator (43);
• the circuit component (7) converts the induced current generated by the coil structure (42) cutting the magnetic field of the magnetic pendulum (41), as well as the current produced by the generator (43) converting the kinetic energy of the magnetic pendulum (41) into electrical energy, into direct current to charge the battery (3).
