Camera module and bracket thereof

Abstract

The invention relates to a camera module and a bracket thereof. The bracket comprises a barrel, a mounting plate and lugs, wherein the barrel has a first end face and a second end face which are opposite to each other; the mounting plate has a first surface and a second surface which are opposite to each other; the mounting plate is arranged in the barrel; the first surface and the first end face are flush with each other and constructed a mounting surface; the mounting plate is provided with a light hole passing through the first surface and the second surface; the light hole is used for accommodating an infrared cut-off filter of the camera module; the lugs are arranged on the mounting plate; one side of each lug far away from the mounting plate is used for carrying a voice coil motor of the camera module; a plurality of lugs are distributed in such a way that the voice coil motor of the camera module can be erected on the lugs under the condition of no external force; a space between the mounting surface and the lugs far away from the mounting surface is taken as a glue accommodating area; and the second end face is used for connecting a circuit board of the camera module. During assembly of the bracket, the overall dimension of the camera module can be ensured, and the voice coil motor can be prevented from being separated from the bracket in the case of falling.

Description

technical field [0001] The invention relates to the technical field of camera equipment, in particular to a camera module and its bracket. Background technique [0002] A miniature camera module with focusing function usually includes a bracket, an infrared cut filter, a circuit board, an image sensor chip, a lens, and a voice coil motor for realizing the focusing function. The bracket has a light-transmitting hole that runs through its upper and lower surfaces, the infrared cut-off filter is arranged in the light-transmitting hole, the circuit board is arranged at one end of the bracket, and the circuit board, the infrared cut-off filter and the bracket cooperate to form a closed receiving cavity . The image sensor chip is arranged on the circuit board and accommodated in the receiving cavity. The voice coil motor is arranged on the end of the bracket away from the circuit board, the lens is installed in the voice coil motor, and the voice coil motor drives the lens to ex...

AI Technical Summary

Problems solved by technology

[0003] In a traditional camera module, the voice coil motor is glued to the mounting surface. After dispensing glue on the mounting surface, the voice coil motor and the bracket are squeezed against each other, and the glue is easily squeezed out completely, resulting in the The amount of glue between the bracket and the bracket is small, and some areas even have no glue, which makes the voice coil motor and the bracket not firmly connected, and it is easy to separate when dropped

There is a lot of glue extruded, even if the overflow groove is set on the edge of the mounting surface, the glue will flow to the outer wall of the bracket, causing the actual size of the bracket to exceed the original design size, that is, the actual size of the camera module Exceeding the original design size, which leads to unqualified dimensions of the camera module
