Abstract

The invention discloses a VCM shrapnel for a mobile phone camera, comprising a square shrapnel body, the four corners of the shrapnel body are chamfered, and a circular inner hole for the lens to pass is opened at the geometric center of the shrapnel body. The diameter of the shaped inner hole is smaller than the side length of the square body, and each side of the shrapnel body is provided with a concave notch at the inner edge of the circular inner hole, and the four chamfers of the shrapnel body are provided with elastic parts of the same shape. The elastic part includes three "口"-shaped connecting plates with the same structure, and the combination of the three "口-shaped" connecting plates is arranged in the shape of "品". The structure of the present invention is simple, each connecting plate evenly disperses the force of the shrapnel, improves the stability of the shrapnel, prevents the slight movement of the shrapnel position due to external force, and improves the shooting quality and shooting effect.

Description

technical field [0001] The invention relates to the technical field of autofocus motors for mobile phone cameras, in particular to a VCM shrapnel for mobile phone cameras. Background technique [0002] Mobile phone cameras widely use VCM (Voice Coil Motor, Voice Coil Motor) to realize the auto-focus function, and the position of the lens can be adjusted through the VCM to present a clear image. The VCM shrapnel used in the mobile phone camera is mainly composed of a coil, a magnet group and a shrapnel. The coil is fixed in the magnet group by two upper and lower shrapnels. When the coil is energized, the coil generates a magnetic field. The coil magnetic field interacts with the magnet group, and the coil moves upward. The camera locked in the coil moves along with it. When the power is cut off, the coil returns under the elastic force of the shrapnel to realize the auto-focus function. [0003] With the rapid development of mobile phone application technology, mobile phone...
