A magnetic buckle assembly includes first buckle component, a second buckle component for mating with the first buckle component, a switch movably disposed on the second buckle component, an operating component slidably disposed on the second buckle component and for driving the switch to move. The first magnetic component, a first magnetic component disposed on the first buckle component, a second magnetic component disposed on the switch and for magnetically attracting or repelling the first magnetic component, and a latch movably disposed on the second buckle component and for engaging with the first buckle component. The latch moves along with sliding movement of the operating 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 slide to disengage the latch from the first buckle component.
