Abstract
A panel release device includes a magnetic buckle device including a first buckle member and a second buckle member respectively attached to a preset first panel and a preset second panel and respectively composed of a columnar magnetic body, a non-magnetic conductive component and a magnetic conductive component, and a magnetic key composed of a ring-shaped magnetic body with N magnetic components and S magnetic components stacked vertically. When the ring-shaped magnetic body is aligned with the non-magnetic conductive component with the same polarity, the mutually repulsive state between the ring-shaped magnetic body and the magnetic buckle device is changed to a mutually attractive and fitting state, so that the first buckle member and the second buckle member are in a mutually repulsive state with the same polarity, and the preset first panel and the preset second panel are unlocked and separated.
