Patent ID: 8014844

Claim:
An electromagnetic sliding mechanism, comprising: a fixing base provided with at least one electromagnetic element; a sliding piece slidably provided at the fixing base and sliding between a first position close to the electromagnetic element of the fixing base and a second position away from the first position, the sliding piece being provided with at least one electromagnetic element corresponding to the electromagnetic element of the fixing base; and an elastic piece having a first end and a second end, the first end being pivotally connected to the fixing base, the second end being pivotally connected to the sliding piece and moving synchronously with the sliding piece; whereby after the electromagnetic element of the fixing base and the electromagnetic element of the sliding piece are electro-magnetized, a magnetic repulsive force larger than a resistant force of the elastic piece is generated between the electromagnetic element of the fixing base and the electromagnetic element of the sliding piece, so that the sliding piece automatically slides from the first position to the second position; after the connecting portion between the sliding piece and the second end of the elastic piece passes through the connecting portion between the fixing base and the first end of the elastic piece, the electromagnetic element of the fixing piece and the electromagnetic element of the sliding piece are de-magnetized, the elastic piece then expands outwards to apply a thrust to the sliding piece for making the sliding piece to slide toward the second position continuously.
