Description

Camera with shared substrate

Technical Field

The utility model relates to the technical field of camera modules, in particular to a camera with a shared substrate.

Background

In order to have the function of shooing, all need install the camera on the present cell-phone, and based on ordinary shooting and the demand of autodyne, actually including preceding camera and back camera on the cell-phone, preceding camera is used for autodyne, and back camera is used for ordinary shooting. The front camera and the rear camera are mutually independent, and are separately and respectively installed when installed on a mobile phone.

The camera has a certain thickness, after the camera is installed, the thickness of the camera directly influences the thickness of the mobile phone, under the requirement that the thickness of the mobile phone is reduced as much as possible at present, higher requirements are also put forward on the thickness of the camera, and under the condition that the front camera and the rear camera are required to be installed, the total thickness of a camera module installed on the mobile phone is actually the sum of the thicknesses of the two cameras, so that the total thickness of the front camera and the rear camera is larger after the installation.

At present, the thickness of the mobile phone is generally determined according to the total thickness of the camera, or the thickness of the mobile phone is reduced, but the camera is outwards protruded, but the former still does not meet the pursuit of partial consumers for thinner mobile phones, the latter can cause great change on the appearance of the mobile phone, the aesthetic property of the mobile phone is destroyed, and the outwards protruded camera can also cause the mobile phone to be placed in a non-horizontal state, and when the mobile phone falls or slides on a desktop, the camera bears great acting force to cause damage or abrasion, so that a camera with smaller thickness comprising a front camera shooting function and a rear camera shooting function is needed.

Disclosure of Invention

The utility model aims to provide a camera with a shared substrate so as to reduce the thickness of the camera.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the front camera unit comprises a front chip, a front bracket and a front lens, wherein the front bracket is arranged on the substrate, the front lens is arranged on the front bracket, and the front chip is opposite to the front lens and is positioned between the front lens and the substrate; the rear camera shooting unit comprises a rear chip, a rear support and a rear lens, wherein the rear support is attached to the substrate, the rear lens is located on one side, far away from the substrate, of the rear support, the rear chip is opposite to the rear lens and located between the rear lens and the substrate, and the connector is mounted on the substrate.

The beneficial effect of this scheme is:

1. the camera in this scheme includes preceding camera unit and back camera unit, can carry out the selfie respectively and ordinary shooting when using, and compares as preceding camera and back camera respectively with adopting two cameras, only a base plate between preceding camera unit and the back camera unit in this scheme has omitted a base plate with the mode that adopts two cameras, has just also reduced the thickness of a base plate when calculating the thickness, effectively reduces the total thickness of cell-phone camera structure. However, in the current camera field, the main idea is to reduce the height of a single camera by reducing the height of structures such as a lens and a bracket or reducing the thickness of a substrate, but the thickness of two substrates can still be counted after the front camera and the rear camera are installed.

2. The front camera unit and the back camera unit in this scheme are all installed on a base plate, and the camera in this scheme is an integer promptly, only need install once when the installation can, and do not need as the mode that adopts two cameras generally need install before (back) camera again install back (front) camera earlier, so the camera installation in this scheme is more convenient, and because of omitting a base plate for the cost of the camera in this scheme is lower than the cost that adopts two cameras at present.

3. The front camera shooting unit and the rear camera shooting unit in the scheme are connected through the base plate, and when in test, the front camera shooting unit and the rear camera shooting unit can be fixed once, so that the front camera shooting unit and the rear camera shooting unit can be conveniently tested at the same time, the test efficiency is higher, and the test cost can be reduced.

Further, the front bracket comprises a pressing part and a connecting part, the connecting part is positioned at one side of the pressing part far away from the substrate, and the connecting part is sleeve-shaped and is connected with the front lens; the outer diameter of the end of the connecting part far away from the substrate is smaller than that of the end close to the substrate.

The beneficial effect of this scheme is: the connecting portion in this scheme is close to the thickness of compressing tightly portion one side bigger, and under the same circumstances of material again, the intensity of connecting portion in this scheme is bigger, is difficult to damage when receiving pressure.

Further, the compressing part is quadrilateral, the outer diameter of one end of the connecting part, which is close to the substrate, is larger than the side length of the compressing part, the outer wall of the connecting part is provided with a cutting surface, and the outer wall of the connecting part and the projection of the cutting surface along the axial direction are positioned on the compressing part.

The beneficial effect of this scheme is: under the unchangeable circumstances of side length of the clamping part, the connecting portion in this scheme is close to the thickness of one side of base plate bigger to further increase the intensity of connecting portion, and the design of cutting face makes the maximum size of clamping part outer wall the same with the side length of clamping part, so the outer wall of clamping part in this scheme can not excessively outwards bulge, reduces the space that occupies when installing.

Further, the rear camera unit includes a voice coil motor mounted on the rear mount, and the rear lens is mounted on the voice coil motor.

The beneficial effect of this scheme is: the back camera shooting unit in this scheme can automatic focusing, and the effect of shooing is better.

Further, the device further comprises a locking piece, wherein the locking piece penetrates through the base plate and connects the front support and the rear support with the base plate.

The beneficial effect of this scheme is: because same retaining member can install fore-stock and back support simultaneously on the base plate, can further reduce the use of hardware in the camera in this patent, further reduce the weight of camera.
