Patent number: 7731003Abstract: An axially actuating device having an elastic joining portion is provided, which is used for carrying an object and actuating the object to move axially, and comprises a fixed portion, a moving portion, and a joining member. The joining member is used to combine the fixed portion with the moving portion, such that the fixed portion and the moving portion are axially coupled with each other. Moreover, the fixed portion and the moving portion are respectively a fixed magnet and a coil, such that when a current is applied to the moving portion, the moving portion generates a relative displacement with respect to the fixed portion according to the current, so as to provide an axial displacement. Meanwhile, the moving energy is generated due to the repulsive interaction of the magnetic field, and thus a shock proofing efficacy is also provided.Type: GrantFiled: December 12, 2006Date of Patent: June 8, 2010Assignee: Industrial Technology Research InstituteInventors: Han-Wei Su, Wen-I Wu, Chao-Chang Hu, Yu-Han Chien
