Sliding mechanism and electronic apparatus having same

摘要

An electronic apparatus includes a base, a sliding member and a sliding mechanism. The sliding mechanism includes a first magnet disposed in the sliding member, and a first electromagnet disposed in the base opposite to the first magnet. The first magnet and the first electromagnet are capable of producing a first repulsive force and a first attracting force, the sliding member alternately slides back and forth between the different locations of the base driven by the first repulsive force and the first attracting force.

1. A sliding mechanism for driving a sliding member to slide back and forth between different locations of a base, the sliding mechanism comprising:
a first magnet disposed in the sliding member; and a first electromagnet disposed in the base opposite to the first magnet, and the first electromagnet comprising a first iron core and a first coil wound around the first iron core; wherein when the first coil is to be energized, the first iron core is magnetized by the first coil and has a contrary magnetic polarity with the first magnet, the first magnet and the first iron core repulse each other and produce a first repulsive force to drive the first magnet to move away from the first iron core; when the first coil is to be de-energized, the first iron core is magnetized by the first magnet, the first magnet and the first iron core attract each other and produce a first attracting force to attract the first magnet to move towards the first iron core; the sliding member alternately slides back and forth between the different locations of the base driven by the first repulsive force and the first attracting force; a second magnet disposed in the sliding member and symmetrically arranged with the first magnet; and a second electromagnet disposed in the base opposite to the second magnet, and the second electromagnet comprising a second iron core and a second coil wound around the second iron core; wherein when the first coil is to be energized, the second coil is to be de-energized, the second iron core is magnetized by the second magnet, the second magnet and the second iron core attract each other and produce a second attracting force having the same direction as the first repulsive force to attract the second magnet to move towards the second iron core, and the sliding member is driven by the first repulsive force and the second attracting force to slide to a first predetermined location of the base; when the first coil is to be de-energized, the second coil is to be energized, the second iron core is magnetized by the second coil and has a contrary magnetic polarity with the second magnet, the second magnet and the second iron core repulse each other and produce a second repulsive force having the same direction as the first attracting force to drive the second magnet to move away from the second iron core, and the sliding member is driven by the first attracting force and the second repulsive force to slide to a second predetermined location of the base.
