FIG. 2 shows an embodiment of a conventional camera module 200.

The camera module 200 may refer to a component unit associated with one camera coupled to the mobile terminal 100. Therefore, the camera and the camera module 200 referred to in the present invention may have the same meaning.

The camera module 200 mainly includes a lens unit 201 that adjusts a refractive index from an object, an image sensor 202 that optically recognizes an image of a subject, and a circuit unit that exchanges a current or a signal with a substrate provided in the mobile terminal 100. [ (203).

The above-described configurations are merely examples, and may be provided as a camera module 200 including only some of the configurations as needed, or may be configured as one camera module 200 including other configurations.

The camera module 200 may be connected to the mobile terminal 100 in accordance with the camera module 200. The mobile terminal 100 and the camera module 200 may be connected to each other without any clear distinction between the mobile terminal 100 and the camera module 200, The camera 200 can be mounted.

However, since the present invention assumes that there is a coupling between the housing 210 (see Fig. 3) of the mobile terminal 100 (see Fig. 1A) and the camera 200, It can be a component.

3 is a cross-sectional view of a conventional mobile terminal 100 to which the camera module 200 is coupled.

The lens unit 201 of the camera module 200 is inevitably optically exposed to the outside of the mobile terminal 100. The direction in which the lens unit 201 of the camera module 200 is exposed in the mobile terminal 100 is defined as the F direction which is the front direction of the camera module 200. [

The module case 204 may be configured to mount the lens unit 201 and the image sensor 202 of the camera module 200 and form an outer appearance including the front face of the camera module 200. [

The module case 204 may be constituted only by an inner frame 2041 to be described later or may be constituted by a combination of an inner frame 2041 (see FIG. 7) and an outer frame 2042 (see FIG. 7).

The module case 204 of the camera module 200 may form the front surface 206 (see FIG. 6) and the side surface 205 (see FIG. 6) of the camera module 200. At least a part of each of the front face 206 (see FIG. 6) and the side face 205 (see FIG. 6) of the camera module 200 is formed in the housing 210 of the mobile terminal 100 forming the appearance of the mobile terminal 100 And can be mounted opposite to the camera seating part 220 formed.

That is, the camera mount part 220 of the mobile terminal 100 may be formed to correspond to the shape of the module case 204, which is at least a partial area of each of the front surface and the side surface of the camera module 200.

At least a part of the area of the camera module 200 can be stably coupled through the camera mount part 220 of the mobile terminal 100.

The circuit unit 203 may be provided on the rear surface of the camera module 200 and the circuit unit 203 may be electrically connected to the main substrate of the mobile terminal 100 through a flexible substrate or the like.

Or the circuit portion 203 of the camera module 200 may be provided on a flexible substrate and may be directly coupled to a main substrate or the like.

The camera module 200 is separately manufactured, formed, and coupled to the housing 210 of the mobile terminal 100. This coupling can generally be fixed through fitting of the seat portion 220 and the case 204 of the camera module 200. [

The camera module 200 needs to be stably coupled to the seat 220 of the mobile terminal 100. When the subject is photographed through the camera 200, the camera module 200 must be moved at the same angle and displacement as the housing 210 of the mobile terminal 100 so that the camera lens unit 201 can be viewed in a direction intended by the user , The subject can be stably viewed without any tremor.

The lens unit 201 of the camera module 200 needs to be optically exposed to the outside of the housing 210 of the mobile terminal 100.

The housing 210 may include an opening 211 provided in the front direction of the seating part 220 to secure the optical path by exposing the lens part 201 to the outside when the camera module 200 is seated.

The window 212 may be configured to cover at least one area of the housing 210 forming the outer appearance of the mobile terminal 100, In particular, the mobile terminal 100 including the display unit may be provided to cover one area of the front surface of the housing 210 or one area of the rear surface of the housing 210 of the mobile terminal 100 including the rear camera.

The window 212 is transparent in view of the characteristics of the material including glass and the like but covers a part or the like provided inside the window 212 and a printing layer 213 which is opaque paint is printed on the inner side of the window 212 And may be provided between the window 212 and the housing 210.

However, the print layer 213 may be provided except for a region corresponding to the lens unit 201 of the camera module 200. The lens unit 201 of the camera module 200 must be made of a transmissive material since the light reflected from the subject is on an optical path passing through the image sensor 202.

Accordingly, the blank area 214 of the printing layer 213, which is a non-printing area of the opaque paint, can be determined corresponding to the shape of the outer surface of the lens unit 201, that is, the front surface. Since the front surface of the lens unit 201 has a generally circular shape, the blank region 214 of the print layer 213 may also be formed in a circular shape.

The blank area 214 of the printing layer 213 which is an opaque paint printed on the window 211 and the window 211 of the housing 210 may be formed to have a specific size larger than the front area of the lens part 201. This is because the housing 210 or the print layer 213 can not be provided in the optical path corresponding to the maximum angle of view G which is the maximum angle that the lens unit 201 can see.

The center of the opening 211 of the housing 210 and the center of the blank region 214 of the print layer 213 and the center of the lens portion 201 of the printing layer 213 are reduced, The more the center of the image is, the better the purpose such as aesthetic.

Nevertheless, since the size of the camera mount 200 and the camera mount 220 of the housing 210 is very small, due to the tolerances generated in manufacture and the eccentricity generated due to the flow of the camera module 200 after coupling, There is a limitation in reducing the blank area 214 of the layer 213. [

The distance D between the boundary formed by the maximum angle of view G of the camera 200 and the blank area 214 on the plane on the window 212 on which the print layer 213 is provided is 0.3 mm There should be more free space.

FIG. 4A is a schematic view of the conventional mobile terminal 100 camera seat 220 viewed from the inside, and FIG. 4B is a sectional view taken along the line B-B 'of FIG. 4A.

The inner side of the camera mount part 220 of the mobile terminal 100 may include a rib 310. The rib 310 may serve to fix the camera module 200 and the camera mount 220 so that they do not flow after being coupled.

The ribs 310 may be integrally formed with the same material as the housing 210 of the mobile terminal 100. Therefore, the rib 310 may include a plastic material such as polycarbonate, polyamide or the like, or may include a material such as aluminum or an aluminum-magnesium alloy if necessary.

Referring to FIG. 3 again, the rib 310 may include a guide inclined portion 311 for providing a path for facilitating the coupling of the camera module 200 to the camera mount 220.

The ribs 310 may cause shrinkage after bonding and may cause variations in the manufacturing process.

Therefore, it is difficult to prevent eccentricity from occurring when the camera module 200 and the camera mount 220 are coupled and fixed by the ribs 310.

5 is a cross-sectional view taken along the line A-A 'in Fig.

At least a part of the configuration of the conventional camera module 200 and the mobile terminal 100 described above may be the same unless otherwise noted.

The side buffering silicone part 230 may protrude from at least one side surface 205 of the camera module 200. The protruding area of the side buffering silicone part 230 may be in contact with the camera mounting part 220.

The seating groove 215 may be provided corresponding to an area where the side buffering silicon part 230 contacts the camera seating part 220.

The side buffering silicone part 230 of the camera module 200 and the seating groove 215 of the housing 210 can be engaged and fixed to each other. The side shock absorbing silicone part 230 stably supports both side surfaces of the seating part 220 and can play a role of minimizing the occurrence of clearance in the seating part 220 or the movement in the T direction in the side direction have.

6 is a front perspective view of the camera module 200. FIG.

The side buffering silicon part 230 may be provided in a strip shape along the side surface 205. When the strip-shaped side buffering silicon part 230-1 is formed, the seating groove 215 may also be formed along the side surface of the camera seating part 220 in a strip shape.

The strip-shaped lateral buffering silicon portion 230-1 can be made larger in area than the lateral buffering silicon portion 230-3 (see FIG. 9) in dot-shaped contact with the camera seating portion 220, .

The strip-shaped side buffering silicon portion 230-1 may have a single strip shape, or may have a plurality of strip shapes if necessary. The connection between the camera module 200 and the housing 210 can be made more rigid when formed of a plurality of strip-shaped side buffering silicone portions 230-1.

Referring again to FIG. 5, the seating surface 2151 of the seating groove 215 may include a shape corresponding to the outer surface 2301, which is the protruding region of the side buffering silicon portion 230.

Therefore, when the outer surface 2301 of the band-shaped lateral cushioning silicone portion 230-1 has a curved surface, the seating surface 2151 of the seating groove 215 may also have a curved shape.

When the outer surface 2301 of the side buffering silicon part 230 has a convex shape, the seating surface 2301 of the seating groove 215 may have a concave shape corresponding thereto.

Due to the corresponding shape, not only the camera module 200 flows in the T direction in the lateral direction in the camera mount portion 220 of the housing 210 but also flows in the vertical direction F direction or the direction opposite to F There is an effect that can be prevented.

The outer side surface 2301 of the side buffering silicon portion 230 having a curved surface shape and the seating surface 2151 of the seating groove 215 may each have a certain radius of curvature. The curvature radius D1 of the outer side surface 2301 of the side buffering silicon part 230 may be equal to or greater than the curvature radius D2 of the seating surface 215. [

When the curvature radius D1 of the outer side surface 2301 of the side buffering silicone part 230 is equal to the curvature radius D2 of the seating surface 215 of the seating groove 215, the surface area of the contact between the camera module 200 and the seating part 220 is maximized So that it can be stably bonded.

Or when the curvature radius D1 of the outer side surface 2301 of the side buffering silicone part 230 is larger than the curvature radius D2 of the seating surface 215 of the seating groove 215, It is possible to minimize the possibility of flowing upward and downward, that is, in the direction F or in the direction opposite to the direction F.

A gap S is formed between the side surface of the camera module 200 and the side surface of the camera mounting portion 220 even when the outer surface 2301 of the side buffering silicone portion 230 is in contact with the mounting surface 2151 of the mounting groove 215 Lt; / RTI > The gap S is compensated when there is a manufacturing tolerance or a shaking due to a clearance so that the camera module 200 and the camera mount 220 of the housing 210 are directly in contact with each other, It is possible to minimize the space to wear.

The size of the gap S may be about 0.15 mm.

The side buffering silicon portion 230 may comprise an elastic material. The side buffering silicon portion 230 may comprise a rubber, such as silicone, or natural rubber. When the camera module 200 is moved in the lateral direction by the flow to generate eccentricity, the elastic material is compressed or tensioned by the external force, The eccentricity naturally can be minimized by the tensile force generated in the tensile region and the compressive force generated in the tensile region, that is, by the density difference of each region.

Figs. 7A and 7B are sectional views of the camera module 200 taken along the line A-A 'in Fig. 1A.

The inner frame 2041 generally includes a material such as SUS, while the side buffering silicon portion 230 includes a material having elasticity such as silicon, so that a combination of both structures is problematic.

The side buffering silicone part 230 may be formed in combination with an inner frame 2041 of different material surrounding the entire length of the camera module 200. That is, the side buffering silicone part 230 may be coupled to the inner frame 2041 by a double injection method. Alternatively, the side buffering silicone part 230 may be integrated with the outer frame 2042 of the same kind of material forming the outer wall of the inner frame 2041, if necessary.

When the side buffering silicone portion 230 is directly coupled to the inner frame 2041 by a double injection method as shown in FIG. 7 (a), the inner frame 2041 is formed so that the inner diameter I is smaller than the outer diameter O And may include a larger injection recess 207.

Alternatively, when the outer frame 2042 is integrated with the outer frame 2042 of the same kind as shown in FIG. 7 (b), only the outer frame 2042 may be coupled to the inner frame 2041 by a double injection method.

In this case, unlike the embodiment of FIG. 7A, the contact area between the inner frame 2041 and the outer frame 2042 is sufficiently wide and no separate injection groove 207 may be provided, thereby simplifying the manufacturing process and reducing the cost. It is possible.

The combined structure of the side buffering silicon part 230 and the inner frame 2041 can be applied not only to the embodiments of the side buffering silicon part 230 described above but also to the various embodiments of the side buffering silicon part 230 It can be applied independently for each example.

Composite formation may refer to a form in which after forming the inner frame 2041, another material is coupled and formed through a double injection method or the like.

FIG. 8 shows another embodiment of a mobile terminal 100 according to the present invention.

In the above embodiment, the curved side buffering silicon part 230 has been described. However, the present invention is not limited thereto and may have various shapes.

For example, the lateral cushioning silicone portion 230 may include a triangular-shaped lateral cushioning silicone portion 230 having two inclined planes protruding in the middle.

Alternatively, the side buffering silicon part 230 may form an asymmetrical side buffering silicon part 230-2 having an inclined part 311 that protrudes further toward the back of the camera module 200.

When the camera module 200 is formed of the asymmetrically shaped lateral cushioning silicone part 230-2, the camera module 200 is relatively easily coupled to the mounting groove 215 of the housing 210, It is possible to have the same effect as hooking the side damping silicone part 230 to the seat part 220 at the same time.

The size of the asymmetrical side buffering silicon part 230-2 may be equal to or greater than the size of the seating groove 215. [ It is possible to expect the same effect as the radius of curvature in the curved side surface buffering silicon part 230-1.

Figure 9 illustrates another embodiment of a camera module 200 associated with the present invention.

The side buffering silicone part 230 may be provided in a dot shape on the side surface of the camera module 200.

At least one dot-shaped lateral buffering silicon part 230-3 may be provided on each side of the camera module 200. [ Four dot-shaped buffering silicon portions 230-3 may be provided at four corners on each side of the camera module 200 for stable coupling.

The front cushioning silicone part 240 protrudes from at least one area of the front surface of the camera module 200 and can contact the front surface area of the camera mounting part 220,

The front buffering silicone part 240 may function to buffer the force acting on the camera module 200 in the direction F, which is the front direction, with the housing 210.

The front cushioning silicone part 240 may replace the front cushioning pad 320 (see FIG. 3), which has been conventionally provided in the front of the camera module 200 and the camera seating part 220 of the housing 210.

When the front buffering silicon part 240 includes the same material as the lateral buffering silicon part 230, it can be formed in a single forming process, thereby simplifying the production process and saving production cost.

Particularly, when the side buffering silicon part 230 is coupled to the outer wall of the inner frame 2041 of the camera module 200 together with the outer frame 2042 including the same or similar material as shown in FIG. 7 (b) The outer frame 2042 may be formed to enclose at least a partial area of the front surface of the camera module 200.

In this case, the outer frame 2042 provided on the front surface and the front buffering silicon part 240 may be integrally formed. Both the side buffering silicon portion 230 and the front buffering silicon portion 240 may be formed integrally with the outer frame 2042 and coupled to the inner frame 2041. When the side buffering silicone part 230, the front buffering silicon part 240 and the outer frame 2042 are integrally provided and are coupled to the inner frame 2041 by the double injection molding method, the overall coupling reliability can be improved, Can be saved.

5, the distance D between the border formed by the maximum angle of view G of the camera 200 and the blank area 214 on one side of the window 212 where the opaque paint is printed is less than 0.3 mm . Even if the reliability of the eccentricity prevention of the camera module 200 increases and the distance D becomes less than 0.3 mm, there is almost no possibility that the print layer 213 is included in the maximum angle of view G. [

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
