Abstract

A camera module structure is provided to enable a lens holder to be coupled to a housing by pressing the lens holder at one time and obtain protection against dust by a gasket. A camera module structure has a lens holder(10) and a housing(30). The lens holder is coupled to the housing. Protruded portions(20) are in the outside of the lens holder. Recessed portions(40) are in the inside of the housing. When the lens holder is coupled to the housing, the protruded portions are fitted to the recessed portions by pressure at one time. A gasket(50) is in the inside of the housing.

The present invention relates to a camera module structure.

1 is a cross-sectional view of a conventional camera module, Figure 2 is a cross-sectional view before coupling of the lens holder and the housing of FIG.

In general, the camera module 100 includes a lens unit 110, a lens holder 120 covering the lens unit 110, a housing 130 in contact with the outside of the lens holder 120, and the like. And an IR filter 140 provided at the rear of the lens holder 120, an image sensor 150 provided at the rear of the IR filter 140, and a rear surface of the image sensor 150. It is configured to include a printed circuit board 160.

The camera module having the above configuration receives the optical image of the subject and receives the lens unit 110 to the IR filter 140, and the IR filter 140 blocks the infrared rays from the received optical image and then the image sensor ( 150, the image sensor 150 is configured to convert the irradiated optical image into an electrical signal and output the electrical signal.

The lens holder 120 is provided with a first threaded portion 121, and the housing 130 is provided with a second threaded portion 131 that engages with the first threaded portion 121.

Thus, the lens holder 120 is fastened to the housing 130 by the first screw portion 121 is coupled to the second screw portion 131, and the focusing process is performed separately.

However, in the conventional camera module structure as described above, the process of fastening the lens holder 120 to the housing 130 and the focusing process are performed manually, resulting in a decrease in work efficiency and a product deviation, and the fastened lens holder 120. ) Is weak to fall or impact.

Therefore, the present invention has been invented to solve such a problem, and an object of the present invention is to provide a camera module structure configured such that the coupling between the lens holder and the housing is made at a suitable pressure.

In order to achieve the above object, the present invention includes a lens holder and a housing to which the lens holder is coupled, the outer surface of the lens holder is provided with a protrusion, the inner surface of the housing is provided with a recess, the lens holder is a housing Provided is a camera module structure in which the protrusion is drawn in and seated at a single pressure in the recess when coupled thereto.

In addition, two or more protrusions may be provided on an outer surface of the lens holder, and a locking jaw may be provided on an upper end of the concave portion.

In addition, a gasket may be provided on an inner surface of the housing, and the gasket may be provided on a bottom circumference of the inner surface of the housing.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

3 is a cross-sectional view before the lens holder and the housing of the camera module structure of the present invention, Figure 4 is a cross-sectional view of the lens holder and the housing of Figure 3 are combined.

The camera module structure of the present invention includes a lens holder 10 and a housing 30 to which the lens holder 10 is coupled.

The lens holder 10 is provided with a protrusion 20 on an outer side surface, and the housing 30 is provided with a recess 40 on an inner side surface.

In addition, two or more protrusions 20 are provided on the outer surface of the lens holder 10, and the recesses 40 are provided in the same number as the protrusions 20.

In addition, a locking jaw 42 is provided at the upper end of the recess 40, and a gasket 50 is provided at the lower periphery of the inner surface of the housing 30 to block external dust.

Referring to the operation of the present invention having the structure as described above is as follows.

When the lens holder 10 is coupled to the housing 30 in the manufacturing process of the camera module, the protrusion 20 is drawn into the recess 40 at a single pressure and seated therein.

The protruding portion 20 is formed of an elastic material so that when the protruding portion 20 is applied to a predetermined range in a state in which the protruding portion 20 is caught by the locking jaw 42, it causes elastic deformation and is seated on the concave portion 40.

And the gasket 50 provided between the lower end of the lens holder 10 and the lower periphery of the inner surface of the housing 30 serves to prevent dust and the like from entering.

After the lens holder 10 is coupled to the housing 30 as shown in FIG. 4, the protrusion 20 and the recess 40 are cured by bonding.

At this time, the focusing error can reduce the deviation between the products because the protrusion 20 is always in constant contact with the recess 40 provided with the locking step 42.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are not intended to limit the technical spirit of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.

As described above, according to the present invention, the lens holder is easily and accurately coupled to the housing by applying a single pressure, and the dustproof effect is provided by the gasket.
