Problems solved by technology

[0003] However, in the prior art, the reed conductive design is conventionally adopted. This kind of scheme is bulky and has poor anti-magnetic interference ability. The reed is easy to break when it is impacted or fatigued, resulting in an open circuit of the product. In the conventional scheme, a separate lower reed is used. After the product is assembled, the symmetry of the reed is relatively large, and the inclination is relatively large when the product is in motion

Abstract

A non-reed conductive type closed-loop motor comprises a casing, an upper spring, a lens, magnets, a lower reed, an FPCB, a chip, a capacitor, coils, a base and a terminal. The lens is arranged in thecasing and replaces a routine carrier structure, and the motor size can be reduced effectively; the upper spring and the lower reed are arranged on and under the lens respectively, the integral lowerreed is connected by an inner frame, and the precision after assembling is high; the magnets are arranged in the two sides of the lens respectively; the base and terminal in injection molding is arranged in the bottom of the casing; the capacitor and chip are fixed on the FPCB, and the FPCB is fixed between the base and the casing; the FPCB sleeves the terminal; and coils of an annular railway structure are welded to the two sides of the base respectively. An electromagnetic force can be improved effectively, the coils are welded to the Base, the non-reed conductive type design is used, and motor failure caused by reed fracture after reliable impact can be avoided effectively.

Description

technical field [0001] The invention relates to the technical field of voice coil motors, in particular to a non-reed conductive closed-loop motor. 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 currently for the camera automatic focusing device, Automatic focusing with voice coil motor structure is still the most cost-effective method. By fixing the optical lens on the rotor frame of the voice coil motor, the rotor acts as the power unit for moving the lens, and connects the rotor frame of the voice coil motor with the stator through the shrapnel. When the motor is energized, the rotor frame will move along the optical axis of the lens. Linear motion, so as to realize the automatic focusing function. The function of the lens is to carry the lens and the coil to move inside the motor...
