Problems solved by technology

[0003] At present, the dual-camera technology uses the combination of two single cameras. In the module stage, two separate autofocus devices are combined together through other components, resulting in a waste of cost and space for the focus device. Two separate focus devices They act separately, so the shooting quality of the dual camera cannot be guaranteed

Embodiment Construction

[0038] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings.

[0039] as attached figure 1 , 2 As shown in and 3, the present invention discloses a dual-camera autofocus device, comprising a base 1 and a housing 9, the base 1 is provided with a first base through hole 101 and a second base through hole 102, and the housing 9 A first housing through hole 901 and a second housing through hole 902 are provided. The housing 9 is mounted on the base 1 to form an installation cavity, and the first base through hole 101 is facing the first housing through hole 901 and the second housing through hole 901. The second base through hole 102 is facing the second housing through hole 902. The base 1 is integrally formed of metal and plastic. The first focusing mechanism facing the hole 901, and the second focusing mechanism facing the second base through hole 102 and the s...

Abstract

The present invention provides a dual-camera automatic focusing device. The dual-camera automatic focusing device comprises a pedestal, a carrier, a focusing coil, a focusing magnet, a lower spring, an upper spring, a frame and housing. The focusing coil is wound at the outer side of the carrier, the focusing magnet is symmetrically arranged at the outer side of the focusing coil, and the focusing coil and the focusing magnet generate the interaction of the electromagnetic force to allow the focusing coil to drive the carrier with a lens to move up and down so as to realize the automatic focusing functions of a voice coil motor. The dual-camera automatic focusing device is configured to divide two monomer voice coil motors and assemble the two monomer voice coil motors to be a dual-camera module group and unify the two monomer voice coil motors to be a focusing device with two driving lenses in one monomer so as to realize the camera functions of enlarging the visual angle range covered by the lens, the distance measurement, the dark light enhancement, the 3D shooting and the like, effectively save the space of module group products occupied in the mobile phone and improve the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of micro and special motors, and in particular relates to a device capable of realizing dual-camera autofocus mainly applied to camera modules in portable consumer electronic products (such as smart phones). Background technique [0002] With the development of smart phones, people have higher and higher requirements for the functions of smart phones, especially the camera function of smart phones. In order to improve the shooting effect and clarity of the mobile phone, meet the future 3D vision, and simulate the effect of human eyes seeing external things, due to the structure of a single camera, it can only shoot a certain range at a time, and the picture is a 2D picture. In order to achieve the above high requirements, Dual camera technology was born. [0003] At present, the dual-camera technology uses the combination of two single cameras. In the module stage, two separate autofocus devices are combine...
