Problems solved by technology

However, macro photography usually requires photographing the subject at close range, and the closer the working distance, the more motor travel is used
The camera module with telephoto shooting function currently configured in mobile phones, due to the short stroke of the voice coil motor, the focusing distance may exceed the maximum stroke of the voice coil motor, making it difficult to focus when taking macro shots, which in turn makes the macro The effect of the filming is not good

Abstract

The invention provides a voice coil motor, a camera module and an electronic device. The voice coil motor comprises a base (110); the sliding rail assembly is arranged in the front-back direction; the movable seat (120) is used for bearing a first lens and is arranged on the base (110) in a sliding manner through the sliding rail assembly; the first electromagnetic driving assembly (130) and the second electromagnetic driving assembly (140) are used for providing driving force for the movable seat (120) so as to drive the movable seat (120) to slide in the front-back direction relative to the base (110); the first electromagnetic driving assembly (130) and the second electromagnetic driving assembly (140) are arranged on the two sides of the sliding rail assembly respectively. According to the voice coil motor, the structure of the voice coil motor is improved, so that the voice coil motor has a large stroke, and the use requirements of long-focus shooting and macro shooting can be met at the same time.

Description

technical field [0001] The present application relates to the field of image technology, and more specifically, to a voice coil motor, a camera module and electronic equipment. Background technique [0002] In recent years, with the development of optical imaging technology, people have higher and higher requirements for the camera function of portable electronic devices. It is further required that the camera module configured on the electronic device can realize telephoto shooting and macro shooting. [0003] Currently, a voice coil motor (VCM) is usually used to focus on the camera module. Since the focal length of the telephoto shooting is short, the required motor travel is small, so that the current voice coil motor can meet the requirements of the telephoto shooting. However, macro photography usually requires photographing the subject at close range, and the closer the working distance, the more motor travel is used. The camera module with telephoto shooting funct...
