In the above process, the suspension 12 moves down onto the top plate 111.

There are two ways in which the suspension 12 can be moved downward. The first method comprises the following steps: in the descending process of the suspension 12, the control board controls the matching portion 131 to still maintain the power-on state, that is, the suspension 12 still receives the magnetic repulsion force in the downward moving process, and the magnetic repulsion force slows down the downward moving speed of the suspension 12, so that the suspension 12 and the top plate 111 can be prevented from being damaged due to too fast descending speed. And the second method comprises the following steps: during the lowering of the suspension 12, the control board disconnects the mating portion 131 from the power source, i.e., the suspension 12 falls onto the top plate 111 only under the action of gravity.

Referring to fig. 1, the top plate 111 is recessed downwards to form a receiving groove 111a, and the receiving groove 111a is used for receiving the suspension 12. The cross-section of the receiving groove 111a may be circular or square, so that the receiving groove 111a is adapted to the shape of the suspension 12. The suspension member 12 is accommodated in the accommodating groove 111a, so that the suspension member 12 is prevented from moving freely on the top plate 111, and the suspension effect of the suspension member 12 after the user opens the box cover 15 is affected.
