Abstract

A magnetic buckle assembly includes a first buckle component, a second buckle component, a switch, an operating component, a first magnetic component, a second magnetic component and a latch. The switch is movably disposed on the second buckle component. The operating component is linked to the switch. The first magnetic component is disposed on the first buckle component. The second magnetic component is disposed on the switch. The latch is movably disposed on the second buckle component and for engaging with the first buckle component to prevent separation of the first buckle component and the second buckle component. The operating component drives the switch to move to change a direction of a magnetic force of the second magnetic component acting on the first magnetic component when the operating component is operated to disengage the latch from the first buckle component.

First claim
