1. A hinge assembly, comprising:
a hinge body comprising a folded state and an unfolded state;
a driving rod, a first end of the driving rod being slidably coupled to the hinge body, wherein when the hinge body is switched to the folded state or the unfolded state, the driving rod slides relative to the hinge body in a first direction, the first direction being a length direction of the driving rod;
a magnetic assembly slidably coupled to a second end of the driving rod along the first direction; and
a limiting assembly comprising a locked state and an unlocked state, a part of the limiting assembly being located between two opposite surfaces of the driving rod and the magnetic assembly when the limiting assembly is in the locked state, and the limiting assembly being located outside the two opposite surfaces of the driving rod and the magnetic assembly when the limiting assembly is in the unlocked state,
wherein when the hinge body is in the folded state, the driving rod presses against the magnetic assembly through the limiting assembly along the first direction such that the magnetic assembly is maintained in a first position; and in response to an operation instruction, the limiting assembly is switched to the unlocked state and the magnetic assembly moves from the first position towards the driving rod along the first direction to a second position.
