Embodiment Construction

[0028] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

[0029] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected ...

Abstract

The invention relates to a double-camera module. The double-camera module comprises a circuit board, two image sensors, a base, a housing, a drive mechanism and two lens units. A first accommodating space, a second accommodating space cavity and a third accommodating space are formed in the housing; and the drive mechanism comprises a first carrier, a second carrier, a third carrier, an upper spring leaf, a lower spring leaf, a magnet and a coil. When the coil is electrified by the circuit board, the second carrier which is wound with the coil can move up and down along a direction of optical axis due to the fact that the coil is applied with Ampere force in magnetic fields generated in the magnet; the second carrier is connected with the first carrier and the third carrier by a connecting rod, and therefore, the second carrier can simultaneously drive the first carrier and the third carrier to move up and down, i.e., drive the lens units on the first carrier and the third carrier to move up and down. One drive mechanism is adopted to simultaneously drive the two lens units, and therefore, magnetic interference can be effectively reduced, and the image quality is improved.

Description

technical field [0001] The invention relates to the technical field of camera modules, in particular to a dual camera module. Background technique [0002] At present, electronic devices such as mobile phones, notebook computers, and tablet computers are emerging new technologies that use dual camera modules to shoot the same object at the same time. dimensional image. [0003] A traditional dual camera module consists of two independent camera modules mounted on the same circuit board. Each camera module includes a lens unit, a voice coil motor as a driver and carrying the corresponding lens unit, an image sensor for collecting captured image information, and a circuit for transmitting signals shared by two camera modules plate. The main components of each voice coil motor are coils, magnets and shrapnels. When energized, a current is generated in the coil, thereby inducing a magnetic field of a certain intensity. The coil is subjected to an Ampere force, and the direct...
