The invention relates to a voice coil motor, and particularly relates to a bidirectional conduction type closed-loop motor. The bidirectional conduction type closed-loop motor comprises a shell, a carrier, a base, a gasket, an upper elastic piece, a coil, a magnet, a lower elastic piece and a circuit board, and is technically characterized in that a conductive material belt is arranged in the gasket and is provided with a top panel PIN which is led out of the gasket and extends to the top panel of the motor, and lateral PIN pins which are led out of the gasket and extend to the side surface ofthe shell, the top surface of the shell is provided with a receding notch corresponding to the top panel PIN pin, the circuit board is laterally erected on one side of the base, the shell is providedwith a positioning notch in the position corresponding to the circuit board, the upper end of the circuit board is welded to the lateral PIN pins, the lower end of the circuit board is welded with ametal sheet on the base, the metal sheet is welded with the lower elastic piece, and the lower elastic piece is welded with the wiring part of the coil. The problem that an existing voice coil motor can only be conducted on one side is solved, the processing technology is simplified, the production cost is reduced, and the universality is good.
Description
technical field [0001] The invention relates to the technical field of voice coil motors, in particular to a bidirectional conduction closed-loop motor and a gasket used therein, which are suitable for a lens drive device in a mobile device that can automatically focus a camera along the optical axis. Background technique [0002] Since the voice coil motor (Voice Coil Motor, VCM) has the advantages of simple structure, small size, low energy consumption, no noise, high acceleration, fast response, accurate displacement and low price, so for the camera automatic focusing device at present, The automatic focus function of the voice coil motor is still the most cost-effective solution. By fixing the optical lens on the carrier of the voice coil motor, the carrier acts as the power unit for moving the lens, and connects the carrier and the casing of the voice coil motor through an elastic structure. When the motor is energized, the carrier will move linearly along the optical a...
