Panel release device

A panel release device, comprising:

• a magnetic buckle device comprising a first buckle member attached to a preset first panel and a second buckle member attached to a preset second panel, said preset first panel and said preset second panel being stacked or wedged into each other, said first buckle member and said second buckle member being in a mutually attracted state and having the same structure, said first buckle member and said second buckle member each comprising a columnar magnetic body formed by vertically stacking an S-pole magnetic component and an N-pole magnetic component, a non-magnetic conductive component arranged on a top side of said columnar magnetic body and a magnetic conductive component arranged on an opposing bottom side of said columnar magnetic body;
• and
• a magnetic key composed of a ring-shaped magnetic body formed by vertically stacking an N magnetic component and an S magnetic component, said ring-shaped magnetic body having a hollow inner diameter approximately equal to diameter of said columnar magnetic body;
• wherein when said ring-shaped magnetic body is aligned with and close to said non-magnetic conductive component on the top side of said magnetic buckle device with same polarity, a mutually repulsive state of said ring-shaped magnetic body and said magnetic buckle device is changed to a mutually attractive and fitting state through the flow of magnetic lines of force, and the magnetic field lines at a bottom side of said ring-shaped magnetic body are guided to said magnetic conductive component at the bottom side of the magnetic buckle device, so that said first buckle member and said second buckle member are in a mutually repulsive state with same polarity, and said preset first panel and said preset second panel are in an unlocked and separated state.
