Problems solved by technology

However, the current lens drive mechanisms of handheld devices such as mobile phones usually set the coil on the carrier, and the magnet group matched with the coil is set on the base or the shell. During the movement of the carrier, the coil moves with the carrier, which is easy to cause Circuit instability and reduced lifespan
[0003] In addition, the current mobile phones and other equipment are used in a wide range of scenarios. When used in some places where the environment is not good, impurities such as dust layers can easily enter the interior of the camera device, affecting the imaging effect

Abstract

The invention discloses a lens driving device which comprises a shell, a base, a carrier, a lens driving mechanism and a carrier positioning mechanism. The shell and the base are matched to form a cavity, the carrier, the lens driving mechanism and the carrier positioning mechanism are arranged in the cavity, the lens driving mechanism comprises a driving coil arranged on the base and a magnet set matched with the driving coil, and the carrier positioning mechanism comprises an iron core, a positioning coil, an elastic piece and a frame. The frame is arranged in the shell and fixedly connected with the base, the elastic piece is fixedly connected with the frame and exerts an elastic force on the carrier so as to position the carrier, the iron core is arranged on the frame and provided with the positioning coil, the positioning coil exerts the force on the elastic piece when powered on so that the elastic piece can be separated from the carrier, and therefore the carrier can move in the optical axis direction relative to the base. The driving coil is arranged on the base, the magnet set is arranged on the carrier, and the beneficial technical effects of being stable in power supply performance and long in service life are achieved.

Description

technical field [0001] The invention relates to the field of optical driving, in particular to a lens driving device. Background technique [0002] With the development of technology, many electronic devices (such as smart phones or digital cameras) now have the function of taking photos or recording videos. The use of these electronic devices is becoming more and more common, and they are developing towards the direction of convenience and thinner design, so as to provide users with more choices. However, the current lens drive mechanisms of handheld devices such as mobile phones usually set the coil on the carrier, and the magnet group matched with the coil is set on the base or the shell. During the movement of the carrier, the coil moves with the carrier, which is easy to cause Circuit instability and reduced lifespan. [0003] In addition, the current mobile phones and other equipment are used in a wide range of scenarios. When used in some places where the environmen...
