Description

Technical Field

[0001] This implementation relates to a camera module. Background Technology

[0002] Recently, ultra-miniature camera modules have been developed and are widely used in small electronic products such as smartphones, laptops and game consoles.

[0003] As automobiles become increasingly common, ultra-compact cameras are not only widely used in small electronic products, but also in vehicles. Examples include black box cameras that collect objective data for vehicle protection or traffic accidents, rear-view cameras that allow drivers to monitor blind spots behind the vehicle via a screen to ensure safety when reversing, and peripheral detection cameras that can monitor the vehicle's surroundings.

[0004] Recently, as camera modules have become increasingly high-resolution, the heat dissipation performance of plastic bodies has become a problem. In particular, while conventional plastic bodies are cheaper than metal bodies, their susceptibility to heat dissipation can lead to product degradation during use in high-resolution camera modules. Summary of the Invention

[0005] Technical topics

[0006] The present invention aims to provide a camera module that maximizes heat dissipation performance and minimizes waterproofing issues.

[0007] In addition, the present invention aims to provide a camera module that minimizes assembly time and reduces costs.

[0008] Technical solution

[0009] The camera module according to this embodiment includes: a first body including a top plate and a side plate extending from the top plate; a second body connected to the first body; a lens module, at least a portion of which is disposed inside the first body; a first shielding cover connected to the first body; and a substrate assembly disposed inside the second body, wherein at least a portion of the first shielding cover is configured to be higher than the top plate of the first body and exposed to the outside.

[0010] The first shielding cover includes an upper plate and a side plate extending from the upper plate. The side plate of the first shielding cover includes a first portion connected to the upper plate of the first body and a second portion extending upward from the first body. The second portion of the first shielding cover may not overlap with the upper plate of the first body in a direction perpendicular to the optical axis.

[0011] The length of the first part of the first shield in the optical axis direction may be shorter than the length of the second part of the first shield in the optical axis direction.

[0012] The first part of the side plate of the first shield can be connected to the first body by inserting an injection.

[0013] The first body may include a connecting portion protruding upward from the upper plate of the first body, wherein the connecting portion of the first body may be disposed in the second part of the side plate of the first shield.

[0014] The connecting portion of the first body may include: a first region having a first width in a direction perpendicular to the optical axis; and a second region extending upward from the first region and having a second width smaller than the first width.

[0015] The connecting portion of the first body can be connected to the second portion of the first shield by inserting an injection.

[0016] The second region of the connecting portion of the first body includes a plurality of second regions, wherein the connecting portion of the first body includes a groove formed between the plurality of second regions, and wherein the groove of the connecting portion of the first body may be provided at a corner between the side plates of the first shield.

[0017] The camera module includes a second shielding cover disposed inside the second body, wherein the second shielding cover includes a base plate and a side plate extending from the base plate, wherein the thickness of the side plate of the first shielding cover in the direction perpendicular to the optical axis can be greater than the thickness of the side plate of the second shielding cover in the corresponding direction.

[0018] The second shield can be spaced apart from the first shield in the optical axis direction.

[0019] Beneficial effects

[0020] According to the present invention, a plastic rear body structure that maximizes heat dissipation can be provided.

[0021] In addition, assembly time can be minimized and costs reduced by using injection molding to assemble a cover made of metal and a body made of plastic.

[0022] In addition, the interface between the cover and the back body can be prevented from separating through the pretreatment process of the cover, thereby maximizing the waterproof performance.

[0023] In addition, by forming holes to expose the shielding tank inside the body to the outside, heat inside the camera module can be effectively dissipated to the outside. Attached Figure Description

When the bonding surface of the first shield 200 and the first body 100 is immersed in a specific solution for a specific period of time, nanoscale pores S can be formed on the bonding surface of the first shield 200 and the first body 100. As a result, a portion of the first body 100 made of plastic is melted by the heat generated during the insertion and injection process of the first shield 200 and the first body 100, and can flow into the pores S of the first shield 200. In this case, the bonding force, cohesion, and adhesion between the first shield 200 and the first body 100 can be increased. Furthermore, if the mating surfaces of the first shield 200 and the first body 100 are immersed in a specific solution for a specific period of time, a coating C or film can be formed on the mating surfaces of the first shield 200 and the first body 100. This prevents interface separation between the mating surfaces of the first shield 200 and the first body 100. Additionally, waterproofing between the first shield 200 and the first body 100 can be achieved without separate waterproofing or sealing components.

[0091] The first shield 200 can be fixed to the first body 100 by injection molding. The first shield 200 can also be fixed to the first body 100 by insert molding. Injection molding or insert molding can refer to a molding method that combines a metal component and a plastic component into a single unit. A portion of the first body 100 can be melted by the heat generated during the injection molding process and introduced into the pores S created during the pretreatment of the first shield 200.

[0092] Reference Figure 21 The thickness t1 of the side plate 220 of the first shield 200 in the direction perpendicular to the optical axis can be greater than the thickness t2 of the side plate 420 of the second shield 400 in the direction perpendicular to the optical axis. Since the area of ​​the first shield 200 exposed to the outside is larger than the area of ​​the second shield 400 exposed to the outside, the damage caused to the first shield 200 by external impacts, such as vehicle vibrations, can be minimized.

The cross-sectional area of ​​the first-fourth hole 311-4 can be larger than the cross-sectional area of ​​the first-first hole 311-1. The first-first hole 311-1 and the first-third hole 311-3 can be arranged around the second hole 312 on opposite sides of each other. The first-second hole 311-2 and the first-fourth hole 311-4 can be arranged around the second hole 312 on opposite sides of each other.

In this case, the connector lead-out portion 300 can be mated and connected to the second hole 312 of the base plate 310 of the second body 300.

[0099] The inner diameter of the protruding portion 313 in the direction perpendicular to the optical axis can be smaller than the diameter of the second hole 312 of the base plate 310 in the direction perpendicular to the optical axis. The inner diameter of the protruding portion 313 in the direction perpendicular to the optical axis can be smaller than the diameter of the hole 411 of the base plate 410 of the second shield 400 in the direction perpendicular to the optical axis. The outer diameter of the protruding portion in the direction perpendicular to the optical axis can correspond to the diameter of the second hole 312 of the base plate 310 in the direction perpendicular to the optical axis. At this time, the outer surface of the protruding portion 313 can contact the inner surface of the second hole 312 of the base plate 310 of the second body 300. This minimizes the gap between the second body 300, the connector lead-out portion 330, and the second shield 400, preventing moisture from penetrating the gap. The outer diameter of the protruding portion in the direction perpendicular to the optical axis can correspond to the diameter of the hole 411 of the base plate 410 of the second shield 400 in the direction perpendicular to the optical axis. At this time, the outer diameter of the protruding portion 313 can contact the inner surface of the hole 411 of the base plate 410 of the second shield 400. As a result, the gap between the second body 300, the connector lead-out portion 330 and the second shield 400 is minimized, so that moisture can be prevented from penetrating between the gaps.

[0100] The height of the protruding portion 313 in the optical axis direction can correspond to the thickness of the base plate 410 of the second shield 400 in the optical axis direction. In this case, the upper end of the protruding portion 313 can be located on the same plane as the upper surface of the base plate 410 of the second shield 400. This minimizes the gap between the second body 300, the connector lead-out portion 330, and the second shield 400, preventing moisture from penetrating the gap.

Pre-treatment or metal surface treatment can refer to the process of removing oil adhering to the metal surface and forming a coating or surface treatment layer. When the mating surface between the second shield 400 and the second body 300 is immersed in a specific solution for a specific period of time, nanoscale pores S can be formed on the mating surface between the second shield 400 and the second body 300. Therefore, a portion of the second body 300 made of plastic is melted by the heat generated during the insertion and injection process of the second shield 400 and the second body 300, and can flow into the pores S of the second shield 400. In this case, the bonding force, connection force, and adhesion force between the second shield 400 and the second body 300 can be increased.

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 lens barrel portion 1120. The lower plate 1320 may include a through-hole 1322 extending from the upper surface through the lower surface. The lens 1130 and the image sensor 1412 may face each other in the optical axis direction through the through-hole 1322.

[0198] The upper plate 1330 is connected to the lower plate 1320 via a side plate 1340 and can be disposed on the outer side of the lower plate 1320. The upper plate 1330 can be configured to have a stepped portion in the optical axis direction relative to the lower plate 1320. The upper plate 1330 can form the edge of the first shielding can 1310. The upper plate 1330 can be connected to the first body 1100. A connecting groove 1117 can be formed on the inner surface of the body portion 1110, such that the upper plate 1330 is connected to the connecting groove 1117. The connecting groove 1117 can be formed as a portion of the inner surface of the first protrusion 1113 recessed to the outer side. The connecting groove 1117 can also be formed as a portion of the inner surface of the space portion 1110a recessed to the outer side. The upper plate 1330 can be disposed inside the connecting groove 1117.

[0199] On the lower surface of the lens barrel portion 1120, a protrusion 1121 that protrudes further downward than other areas may be provided. The protrusion 1121 may be located inside the connecting groove 1117. The lower end of the protrusion 1121 may contact the upper surface of the lower plate 1320. The outer surface of the protrusion 1121 may contact the inner surface of the side plate 1340. Therefore, the second shielding canister 1310 can be securely fixed in the first body 1100. The outer surface of the side plate 1340 may be supported by the inner surface of the first protrusion 1113. The outer surface of the side plate 1340 may contact the inner surface of the first protrusion 1113.

[0200] The first shielding tank 1310 can be integrally formed by molding metal. The upper plate 1330, side plate 1340 and lower plate 1320 of the first shielding tank 1310 can be integrally formed by molding metal.

[0201] The first shielding can 1310 may be surface-treated with a metal. The first shielding can 1310 may be pre-treated. The mating surfaces of the first shielding can 1310 and the first body 1100 may be surface-treated with a metal. The mating surfaces of the first shielding can 1310 and the first body 1100 may be pre-treated. The first shielding can 1310 may undergo a metal surface pre-treatment process between insertion and injection into the first body 1100. The first shielding can 1310 may be formed of aluminum. At least a portion of the first shielding can 1310 may be formed of aluminum. The first shielding can 1310 may be formed of a metal with high thermal conductivity. Pre-treatment or metal surface treatment may refer to the process of removing oil adhering to a metal surface and forming a coating or surface treatment layer C. In this case, the surface treatment layer may refer to a broader concept including the coating C or a film layer. The surface treatment layer may include the coating C. The surface treatment layer may include a film layer. When the bonding surfaces of the first shielding can 1310 and the first body 1100 are immersed in a specific solution for a certain period of time, nanoscale pores S can be formed on the bonding surfaces of the first shielding can 1310 and the first body 1100. As a result, the plastic portion of the first body 1100 melts due to the heat generated during the insertion and injection process of the first shielding can 1310 and the first body 1100, and can flow into the pores S of the first shielding can 1310. In this case, the bonding force, connection force, and adhesion force between the first shielding can 1310 and the first body 1100 can be increased. Furthermore, if the bonding surfaces of the first shielding can 1310 and the first body 1100 are immersed in a specific solution for a certain period of time, a coating C or film can be formed on the bonding surfaces of the first shielding can 1310 and the first body 1100. This prevents interfacial separation between the bonding surfaces of the first shielding can 1310 and the first body 1100. In addition, waterproofing between the first shielding tank 1310 and the first body 1100 can be achieved without separate waterproofing or sealing components.

[0202] The first shielding can 1310 can be fixed to the first body 1100 by insert molding. Insert injection or insert molding can refer to a method of integrating a metal component and a plastic component. A portion of the first body 1100 can be melted by heat generated during the insert injection process and can be introduced into the pores S created during the pretreatment of the first shielding can 1310.

[0203] A hole 1112 can be formed in the upper surface of the body portion 1110, penetrating both the upper and lower surfaces to expose the first shielding canister 1310 to the outside. The upper plate 1330 of the first shielding canister 1310 can be exposed upwards through the hole 1112. Therefore, the heat generated in the camera module 20 can be easily dissipated to the outside.

[0204] Specifically, an edge portion 1111 may be provided on the upper surface edge of the body portion 1110. The edge portion 1111 may be formed to protrude upward from another area on the upper surface of the body portion 1110 that is located inside. A hole 1112 may be provided between the edge portion 1111 and the lower end of the lens barrel portion 1120. A plurality of holes 1112 may be provided spaced apart from each other. A connecting portion 1114 may be provided between the plurality of holes 1112 to connect the edge portion 1111 to the lower end of the lens barrel portion 1120. The plurality of holes 1112 may be spaced apart from each other by the connecting portion 1114. The plurality of holes 1112 may be provided along the circumference of the lens barrel portion 1120.

[0205] Holes 1112 can be respectively disposed in the four corner regions of the body portion 1110. Holes 1112 can be shaped to connect adjacent sides on the upper surface of the body portion 1110 to each other. Specifically, holes 1112 may include: a first hole 1112a, forming a first side; a second hole 1112b, forming a second side adjacent to the first side; and a third hole 1112c, connecting the first hole 1112a and the second hole 1112b and forming a corner. The first holes to the third holes 1112a, 1112b and 1112c can communicate with each other. The first hole 1112a and the second hole 1112b can be disposed perpendicular to each other.

[0206] Figure 32 This is an example of a modification of the hole inside the camera module according to the second embodiment of the present invention.

[0207] Reference Figure 32 Multiple first holes 1112 can be arranged along the circumference of the lens barrel portion 1120 between the lower end of the lens barrel portion 1120 and the edge portion 1111. Figure 32The illustration shows that the first hole 1112 correspondingly includes: a first hole 1112-1, forming a first side portion; a first hole 1112-2, forming a second side portion; a first hole 1112-3, forming a third side portion; and a first hole 1112-4, forming a fourth side portion. The first hole 1112-1 can be configured to face the first hole 1112-3 around the lens barrel portion 1120. The first hole 1112-2 can be configured to face the first hole 1112-4 around the lens barrel portion 1120. The first hole 1112-1 can be vertically positioned relative to either the first hole 1112-2 or the first hole 1112-4. The first-second hole 1112-2 can be vertically set relative to the first-first hole 1112-1 or the first-third hole 1112-3.

[0208] In this case, the connecting portion 1114 that connects the edge portion 1111 to the lower end of the lens barrel portion 1120 can be provided in the region of each corner forming the body portion 1110.

[0209] Based on the structure described above, a plastic body structure that maximizes heat dissipation can be provided.

[0210] In addition, by using insertion injection to assemble the metal shielding canister and the plastic body, assembly time and costs can be minimized.

[0211] In addition, the interface separation between the shielding can and the main body can be prevented by the pretreatment process of the shielding can, thereby maximizing the waterproof performance.

[0212] In addition, by forming holes to expose the shielding tank inside the body to the outside, the heat radiation inside the camera module can be effectively radiated to the outside.

[0213] Embodiments of the present invention have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that the present invention can be implemented in other specific forms without altering the spirit or essential features. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
