摘要： A tilt preventing structure for electromagnetic driving device comprises: a casing, a driven object (such as lens module), a guiding mechanism and an electromagnetic driving module. The driven object is received within the casing and is movable along an axial direction. The guiding mechanism is furnished inside the casing and is sleeved with the driven object, so as to guide the driven object to move along the axial direction. The electromagnetic driving module comprises a plurality of magnetic elements mounted on the driven object. The guiding mechanism is made of magnetically susceptible material and is nearby one of the magnetic elements. By means of the magnetic pulling force generated by the nearby magnetic elements, the guiding mechanism is pulled by the force and leans against the driven object, so as to minimize the tilts when the driven object is moving relative to the guiding mechanism.

摘要： An electromagnetic lens driving device includes a casing, a lens module, a positioning structure, and an electromagnetic driving module. The lens module is provided in a receiving space defined in the casing. The positioning structure, which is connected between the lens module and the casing, is configured to limit the lens module within the receiving space and generate a frictional force. The electromagnetic driving module is provided in the receiving space and corresponds in position to the lens module. When supplied with electricity, the electromagnetic driving module generates a magnetic force that drives the lens module to move along a central axis. Once the electricity is cut off, the lens module is fixed in position and prevented from moving freely by the frictional force of the positioning structure; hence, the electromagnetic lens driving features economical use of electricity.
