Description

Camera module and terminal equipment

Technical Field

The utility model relates to a camera technical field, in particular to camera module and terminal equipment.

Background

As shown in fig. 1 and 2, the existing camera module mainly includes a lens base 1, a camera PCB 2, and a lens 3, wherein a camera sensor is mounted on the camera PCB 2. There are two main mounting methods for the camera module.

As shown in fig. 1, in a structure and an installation manner of a camera module, a first fixing screw hole is formed in a lens base 1 and a camera PCB 2, and in an assembling process of the camera module, the lens base 1 and the camera PCB 2 are bonded by thermosetting adhesive, and then are fastened by a tapping screw 8 penetrating through the first fixing screw hole. The camera PCB 2 is provided with a second fixing screw hole 91 besides the first fixing screw hole, and when the camera module is installed on the equipment mainboard, the camera module is fixedly installed on the equipment mainboard through a screw penetrating through the second fixing screw hole 91.

As shown in fig. 2, in another structure and installation method of the camera module, a third fixing screw hole 92 is formed in the lens base 1 and the camera PCB 2, and in the assembly process of the camera module, firstly, the lens base 1 and the camera PCB 2 are bonded by thermosetting adhesive to realize preliminary pre-fixing, and then, when the camera module is installed on the equipment main board, the camera module is fixedly installed on the equipment main board through a screw penetrating through the third fixing screw hole 92.

No matter which kind of mode of adoption, all need set up the screw at camera module to utilize the screw to realize the installation of camera module.

For the first mode, at least four screw holes are needed, and simultaneously, the camera module and the whole machine assembly process need to be screwed, so that the process is complex, the assembled whole machine equipment needs more space and positions to place redundant screws, the space of the whole machine equipment at the position of the camera module is occupied, and the optimization of the equipment structure is not facilitated.

For the second mode, although the number of the used screw holes is reduced, the thermosetting adhesive is only used for realizing preliminary pre-fixing, the main fixing means is still screw fastening, the screw holes are required to be drilled for fixing when the whole machine equipment is assembled, otherwise, the camera module cannot be completely fixed on the whole machine equipment, the assembled whole machine equipment still needs space and positions for placing the screws, the space of the whole machine equipment at the position accessory of the camera module is occupied, and the optimization of the equipment structure is not facilitated.

In addition to the above problems, more importantly, the mode of adopting the screw fixation can lead to the focal length change of the camera module, and then causes the reduction of the resolution ratio of the camera. The reason lies in, when fixing through the screw, because the screw snap-on is on the camera module, and then can produce local stress to camera PCB board 2, lead to camera PCB board 2's deformation, this kind of deformation can be transmitted to the camera sensor on camera PCB board 2 for the distance between camera sensor and the 3 bottoms of camera lens changes, thereby arouses the focus change, makes camera resolution ratio obviously descend. In this case, for the standard definition camera, the distance from the camera sensor to the bottom of the lens is not sensitive, and the resolution is not greatly affected.
