Description

[Technical Field]

[0001] This embodiment relates to a camera module. [Background technology]

[0002] In recent years, ultra-miniature camera modules have been developed and are widely used in small electronic products such as smartphones, notebooks, game consoles, etc.

[0003] As automobiles become more widespread, miniature cameras are increasingly used in vehicles as well as in small electronic products. For example, they are equipped with black box cameras for vehicle protection or to collect objective information on traffic accidents, rearview cameras that allow drivers to monitor blind spots at the rear of the vehicle through a screen to ensure safety when reversing, and perimeter detection cameras that can monitor the area around the vehicle.

[0004] In recent years, as camera modules have become more and more pixelated, the heat dissipation performance of plastic bodies has become an issue. In particular, while conventional plastic bodies are cheaper than metal bodies in terms of unit price, they are vulnerable to heat dissipation, and in the case of high-pixel camera modules, the product deteriorates over time. Summary of the Invention [Problem to be solved by the invention]

[0005] This embodiment aims to provide a camera module that can maximize heat dissipation performance and minimize waterproofing problems.

[0006] Also, the present invention aims to provide a camera module that minimizes assembly man-hours and reduces costs. [Means for solving the problem]

[0007] The camera module according to this embodiment includes a first body including a top plate and side plates extending from the top plate, a second body coupled to the first body, a lens module at least a portion of which is disposed within the first body, a first shield cover coupled to the first body, and a board assembly disposed within the second body, wherein at least a portion of the first shield cover is disposed higher than the top plate of the first body and is exposed to the outside.

[0008] The first shield cover may include a top plate and a side plate extending from the top plate, the side plate of the first shield cover may include a first portion coupled to the top plate of the first body and a second portion extending upward from the first portion, and the second portion of the first shield cover may not overlap with the top plate of the first body in a direction perpendicular to the optical axis direction.

[0009] The length of the first portion of the first shield cover in the optical axis direction may be shorter than the length of the second portion of the first shield cover in the optical axis direction.

[0010] The first portion of the side plate of the first shield cover may be coupled to the first body by insert injection.

[0011] The first body may include a coupling portion protruding upward from the top plate of the first body, and the coupling portion of the first body may be disposed on the second portion of the side plate of the first shield cover.

[0012] The coupling portion of the first body may include a first region having a first width in a direction perpendicular to the optical axis direction, and a second region extending upward from the first region and having a second width smaller than the first width.

[0013] The coupling portion of the first body may be coupled to the second portion of the first shield cover by insert injection.

[0014] The second region of the coupling portion of the first body may include a plurality of second regions, and the coupling portion of the first body may include a groove formed between the plurality of second regions, and the groove of the coupling portion of the first body may be disposed at a corner disposed between the side plates of the first shield cover.

[0015] The optical system may further include a second shield cover disposed within the second body, the second shield cover including a bottom plate and side plates extending from the bottom plate, and a thickness of the side plates of the first shield cover in a direction perpendicular to the optical axis direction may be greater than a thickness of the side plates of the second shield cover in a corresponding direction.

[0016] The second shield cover may be spaced apart from the first shield cover in the optical axis direction. [Effects of the Invention]

[0017] According to the present invention, a body structure that can maximize heat dissipation can be provided.

[0018] In addition, the metal cover and plastic body are assembled by insert injection, minimizing assembly man-hours and reducing costs.

[0019] In addition, the cover undergoes a pre-treatment process to prevent interface separation between the cover and the rear body, thereby maximizing waterproof performance.

[0020] In addition, a hole is formed to expose the shield can inside the body to the outside, so that heat inside the camera module can be effectively released to the outside. [Brief explanation of the drawings]

The length of the second portion 222 in the optical axis direction may be longer than the length of the first portion 221 in the optical axis direction. This may maximize the area of ​​the first shield cover 200 exposed to the outside. This allows the heat dissipation performance of the camera module 10 to be maximized.

[0052] The first shield cover 200 may be integrally formed by metal molding. The top plate 210, side plates 220, and corners of the first shield cover 200 may be integrally formed by metal molding. More specifically, the first shield cover 200 may be fixed in a solid rectangular mold. At this time, the first shield cover 200 may be pressed toward the mold to form the shape of the first shield cover. This eliminates the problem of gaps between the side plates that occurs when a cover is formed by bending a plate material to form the side plates and then joining the formed side plates. That is, in the first shield cover 200 of this embodiment, the side plates 220 and the corners are integrally formed, so there is no gap between the multiple side plates 220 or between the side plates 220 and the corners.

[0053] The first shield cover 200 may be metal surface treated. The first shield cover 200 may be pre-treated. A joining surface of the first shield cover 200 with the first body 100 may be metal surface treated. A joining surface of the side plate 220 of the first shield cover 200 with the first body 100 may be metal surface treated. A first portion 221 of the side plate 220 of the first shield cover 200 may be metal surface treated before being insert-molded with the top plate 110 of the first body 100. A contact surface of the second portion 222 of the side plate 220 of the first shield cover 200 with the coupling portion 130 of the first body 100 may be metal surface treated.

[0054] The first shield cover 200 may undergo a metal surface pretreatment process before being insert-molded into the first body 100. The first shield cover 200 may be made of aluminum. At least a portion of the first shield cover 200 may be made of aluminum. The first shield cover 200 may be made of a metal material with high thermal conductivity. Pretreatment or metal surface treatment refers to a process of removing oil from the metal surface and forming a film or coating layer (C). If the mating surface of the first shield cover 200 with the first body 100 is immersed in a special solution for a certain period of time, nano-sized pores (S) can be formed on the mating surface of the first shield cover 200 with the first body 100. As a result, heat generated during the insert-molding process of the first shield cover 200 and the first body 100 can melt portions of the plastic material of the first body 100 and flow into the pores (S) of the first shield cover 200. In this case, the joining strength, bonding strength, and adhesion strength between the first shield cover 200 and the first body 100 can be increased. Also, by immersing the joining surface of the first shield cover 200 with the first body 100 in a special solution for a certain period of time, a coating layer (C) or film layer can be formed on the joining surface of the first shield cover 200 with the first body 100. This can prevent interfacial separation between the joining surfaces of the first shield cover 200 and the first body 100. Also, waterproofing between the first shield cover 200 and the first body 100 can be achieved without the need for a separate waterproofing or sealing member.

[0055] The first shield cover 200 may be fixed to the first body 100 by insert molding. The insert injection or insert molding refers to a molding method that integrates a metal member and a plastic member. Heat generated during the insert injection process may melt a portion of the first body 100 and flow into the pores (S) created during the pre-treatment process of the first shield cover 200.

[0056] 21, the thickness t1 of the side plate 220 of the first shield cover 200 in a direction perpendicular to the optical axis direction may be greater than the thickness t2 of the side plate 420 of the second shield cover 400 in a direction perpendicular to the optical axis direction. Since the area of ​​the first shield cover 200 exposed to the outside is larger than the area of ​​the second shield cover 400 exposed to the outside, this may be intended to minimize damage to the first shield cover 200 from external impacts such as vehicle vibrations.

The first hole 311 may expose the second shield cover 400 to the outside. This allows heat generated in the internal spaces of the first body 100 and the second body 300 to be released to the outside. This allows the camera module 10 to perform a heat dissipation function.

[0060] The first hole 311 may include a plurality of first holes 311. The plurality of first holes 311 may have different shapes.

The cross-section of the 1-3 hole 311-3 may be formed at least partially by a curve. The cross-sectional area of ​​the 1-3 hole 311-3 may be larger than the cross-sectional areas of the 1-1 hole 311-1, the 1-2 hole 311-2, and the 1-4 hole 311-4. The cross-section of the 1-4 hole 311-4 may be formed at least partially by a curve.

The protrusion 313 may form an upper end of the connector lead 330. In this case, the connector lead 300 may be fitted into the second hole 312 of the bottom plate 310 of the second body 300.

[0063] The inner diameter of the protrusion 313 in a direction perpendicular to the optical axis direction may be smaller than the diameter of the second hole 312 of the bottom plate 310 in a direction perpendicular to the optical axis direction. The inner diameter of the protrusion 313 in a direction perpendicular to the optical axis direction may be smaller than the diameter of the hole 411 of the bottom plate 410 of the second shield cover 400 in a direction perpendicular to the optical axis direction. The outer diameter of the protrusion in a direction perpendicular to the optical axis direction may correspond to the diameter of the second hole 312 of the bottom plate 310 in a direction perpendicular to the optical axis direction. In this case, the outer surface of the protrusion 313 may contact the inner surface of the second hole 312 of the bottom plate 310 of the second body 300. This minimizes the gap between the second body 300, the connector outlet 330, and the second shield cover 400, thereby preventing moisture from penetrating between the gaps. The outer diameter of the protrusion in a direction perpendicular to the optical axis direction may correspond to the diameter of the hole 411 of the bottom plate 410 of the second shield cover 400 in a direction perpendicular to the optical axis direction. At this time, the outer surface of the protrusion 313 may contact the inner surface of the hole 411 of the bottom plate 410 of the second shield cover 400. As a result, the gap between the second body 300, the connector outlet 330, and the second shield cover 400 is minimized, thereby preventing moisture from penetrating into the gap.

[0064] The height of the protrusion 313 in the optical axis direction may correspond to the thickness of the bottom plate 410 of the second shield cover 400 in the optical axis direction. In this case, the upper end of the protrusion 313 may be disposed on the same plane as the upper surface of the bottom plate 410 of the second shield cover 400. This minimizes the gap between the second body 300, the connector outlet 330, and the second shield cover 400, thereby preventing moisture from penetrating into the gap. In other words, the gap between the second body 300 and the second shield cover 400 may be waterproofed.

As a result, heat generated during the process of insert injection of the second shield cover 400 and the second body 300 causes portions of the plastic second body 300 to melt and flow into the pores (S) of the second shield cover 400. This increases the joining strength, bonding strength, and adhesion between the second shield cover 400 and the second body 300. In addition, when the mating surface of the second shield cover 400 with the second body 300 is immersed in the special solution for a certain period of time, a coating layer (C) or film layer can be formed on the mating surface of the second shield cover 400 with the second body 300. This prevents interfacial separation between the mating surfaces of the second shield cover 400 and the second body 300. Furthermore, waterproofing between the second shield cover 400 and the second body 300 can be achieved without the need for a separate waterproofing member or sealing member.

The lower plate 1320 may be disposed below the upper plate 1330 based on the optical axis direction. The upper plate 1330 may be disposed outside the lower plate 1320 in a direction perpendicular to the optical axis direction. The lower plate 1320 and the upper plate 1330 may be connected via a side plate 1340. A lower end of the side plate 1340 may be connected to an outer end of the lower plate 1320, and an upper end of the side plate 1340 may be connected to an inner end of the upper plate 1330. As a result, the first shield can 1310 may have a region that is folded at least once. In one example, the upper plate 1330 and the lower plate 1320 may be arranged parallel to each other, and the side plate 1340 may be arranged perpendicular to the upper plate 1330 or the lower plate 1320. The region connecting the upper plate 1330 and the side plate 1340 and the region connecting the lower plate 1320 and the side plate 1340 may be rounded.

[0161] The lower plate 1320 may be disposed such that its upper surface faces the lower surface of the lens 1130 or the lower surface of the barrel portion 1120. A portion of the upper surface of the lower plate 1320 may contact the lower surface of the lens 1130 or the lower surface of the barrel portion 1120. The lower plate 1320 may include a through-hole 1322 that passes through from the upper surface to the lower surface. The lens 1130 and the image sensor 1412 may face each other in the optical axis direction via the through-hole 1322.

[0162] The upper plate 1330 may be connected to the lower plate 1320 via the side plate 1340 and may be disposed outside the lower plate 1320. The upper plate 1330 may be disposed with a step relative to the lower plate 1320 in the optical axis direction. The upper plate 1330 may form an end of the first shield can 1310. The upper plate 1330 may be coupled to the first body 1100. A coupling groove 1117 may be formed on the inner surface of the body part 1110 so that the upper plate 1330 can be coupled thereto. The coupling groove 1117 may be formed by outwardly recessing a portion of the inner surface of the first protrusion 1113. The coupling groove 1117 may be formed by outwardly recessing a portion of the inner surface of the space part 1110a. The upper plate 1330 may be disposed within the coupling groove 1117.

[0163] A protrusion 1121 that protrudes downward more than other regions may be disposed on the lower surface of the barrel portion 1120. The protrusion 1121 may be disposed inside the coupling groove 1117. A lower end of the protrusion 1121 may contact an upper surface of the lower plate 1320. An outer surface of the protrusion 1121 may contact an inner surface of the side plate 1340. Thus, the second shield can 1310 may be firmly fixed within the first body 1100. An outer surface of the side plate 1340 may be supported by an inner surface of the first protrusion 1113. An outer surface of the side plate 1340 may contact an inner surface of the first protrusion 1113.

[0164] The first shield can 1310 may be integrally formed by molding metal. The top plate 1330, the side plate 1340, and the bottom plate 1320 of the first shield can 1310 may be integrally formed by molding metal.

[0165] The first shield can 1310 may be metal surface treated. The first shield can 1310 may be pre-treated. The mating surface of the first shield can 1310 with the first body 1100 may be metal surface treated. The mating surface of the first shield can 1310 with the first body 1100 may be pre-treated. The first shield can 1310 may undergo a metal surface pre-treatment process before being insert-molded into the first body 1100. The first shield can 1310 may be made of aluminum. At least a portion of the first shield can 1310 may be made of aluminum. The first shield can 1310 may be made of a metal material with high thermal conductivity. Pre-treatment or metal surface treatment may refer to a process of removing oil adhering to a metal surface and forming a coating layer or a surface treatment layer. In this case, the surface treatment layer may refer to a coating layer (C) or a generic concept including a coating layer. The surface treatment layer may include a coating layer (C). The surface treatment layer may include a coating layer. When the mating surface of the first shield can 1310 with the first body 1100 is immersed in a special solution for a certain period of time, nano-sized pores (S) can be formed at the mating surface of the first shield can 1310 with the first body 1100. As a result, heat generated during the process of inserting the first shield can 1310 and the first body 1100 melts parts of the plastic first body 1100 and allows the melted parts to flow into the pores (S) of the first shield can 1310. This increases the joining strength, bonding strength, and adhesion between the first shield can 1310 and the first body 1100. In addition, when the mating surface of the first shield can 1310 with the first body 1100 is immersed in the special solution for a certain period of time, a coating layer (C) or film layer can be formed at the mating surface of the first shield can 1310 with the second body 1100. This prevents interfacial separation between the mating surfaces of the first shield can 1310 and the first body 1100. Furthermore, waterproofing between the first shield can 1310 and the first body 1100 can be achieved without the need for a separate waterproofing member or sealing member.

[0166] The first shield can 1310 may be fixed to the first body 1100 by insert molding. The first shield can 1310 may be fixed to the first body 1100 by insert molding. Insert injection or insert molding refers to a molding method that integrates a metal member and a plastic member. Part of the first body 1100 may melt due to heat generated during the insert injection process and flow into the pores (S) created during the pre-treatment process of the first shield can 1310.

[0167] A hole 1112 may be formed on the top surface of the body part 1110, penetrating the top and bottom surfaces and exposing the first shield can 1310 to the outside. An upper plate 1330 of the first shield can 1310 may be exposed upward through the hole 1112. This allows heat generated within the camera module 20 to be easily released to the outside.

[0168] In detail, an end portion 1111 may be disposed on an upper edge of the body portion 1110. The end portion 1111 may be formed to protrude upward more than other regions of the upper surface of the body portion 1110 disposed inside. A hole 1112 may be disposed between the end portion 1111 and the lower end of the barrel portion 1120. A plurality of holes 1112 may be provided and spaced apart from each other. A connecting portion 1114 connecting the end portion 1111 and the lower end of the barrel portion 1120 may be disposed between the plurality of holes 1112. The plurality of holes 1112 may be spaced apart from each other via the connecting portion 1114. The plurality of holes 1112 may be disposed along the circumference of the barrel portion 1120.

[0169] The holes 1112 may be disposed in four corner regions of the body part 1110. The holes 1112 may be shaped to interconnect two adjacent sides on the top surface of the body part 1110. Specifically, the holes 1112 may include a first hole 1112a forming the first side, a second hole 1112b forming the second side adjacent to the first side, and a third hole 1112c connecting the first hole 1112a and the second hole 1112b to form a corner. The first to third holes 1112a, 1112b, and 1112c may be interconnected. The first hole 1112a and the second hole 1112b may be disposed perpendicular to each other.

[0170] FIG. 32 shows a modified example of a hole in a camera module according to the second embodiment of the present invention.

[0171] 32, the first holes 1112 may similarly be provided in plurality and may be arranged along the circumference of the barrel portion 1120 between the lower end and the end portion 1111 of the barrel portion 1120. FIG. 32 illustrates that the first holes 1112 each include a 1-1 hole 1112-1 forming a first side, a 1-2 hole 1112-2 forming a second side, a 1-3 hole 1112-3 forming a third side, and a 1-4 hole 1112-4 forming a fourth side. The 1-1 hole 1112-1 may be arranged to face the 1-3 hole 1112-3 around the barrel portion 1120. The 1-2 hole 1112-2 may be arranged to face the 1-4 hole 1112-4 around the barrel portion 1120. The 1-1 hole 1112-1 may be arranged perpendicular to the 1-2 hole 1112-2 or the 1-4 hole 1112-4, and the 1-2 hole 1112-2 may be arranged perpendicular to the 1-1 hole 1112-1 or the 1-3 hole 1112-3.

[0172] In this case, the connecting portion 1114 connecting the end portion 1111 and the lower end of the barrel portion 1120 may be disposed in the area forming each corner of the body portion 1110 .

[0173] According to the above structure, a plastic body structure that can maximize heat dissipation can be provided.

[0174] In addition, the metal shield can and plastic body are assembled by insert injection, minimizing assembly man-hours and reducing costs.

[0175] In addition, the pre-treatment process on the shield can prevents interface separation between the shield can and the body, thereby maximizing waterproof performance.

[0176] In addition, a hole is formed to expose the shield can inside the body to the outside, so that heat inside the camera module can be effectively released to the outside.
