Description

[Technical Field]

[0001] This embodiment 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, game consoles, etc.

[0003] As automobiles become more widespread, miniature cameras are being used not only in small electronic products but also in vehicles. For example, they are used in dashcams to protect vehicles and provide 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 the case of a camera module mounted on a vehicle, multiple boards may be arranged inside the camera module, and a structure is required that can fix the multiple boards in a spaced-apart state inside the camera module. Summary of the Invention [Problem to be solved by the invention]

[0005] This embodiment provides a camera module that can support multiple substrates and can be firmly bonded to each other while compensating for assembly tolerances between multiple parts. [Means for solving the problem]

[0006] The camera module of this embodiment includes a front body including a hole, a lens module at least a portion of which is coupled to the hole, a rear body coupled to the rear surface of the front body, and a substrate module arranged within the rear body, wherein the substrate module includes a first substrate on which an image sensor is arranged, a second substrate arranged behind the first substrate, and a shielding member coupled to the first substrate and the second substrate, wherein a protrusion is formed on a side of the second substrate, and the shielding member includes a coupling hole to which the protrusion is coupled, and the cross-sectional area of ​​the protrusion is smaller than the cross-sectional area of ​​the coupling hole.

[0007] The inner surface of the coupling hole may include a first surface, a second surface arranged opposite the first surface, a third surface connecting the first surface and the second surface, and a fourth surface connecting the first surface and the second surface and facing the third surface, and the outer surface of the protrusion may contact any one of the first to fourth surfaces.

[0008] The outer surface of the protrusion may be in contact with any one of the first to fourth surfaces and may be spaced apart from the remaining three surfaces.

[0009] The shielding member may include a fence portion disposed between the first substrate and the second substrate, and a connecting portion protruding downward from a lower end of the fence portion and having the connecting hole formed therein, and a groove into which the connecting portion is connected may be formed on a side surface of the second substrate, and the protrusion may be disposed on a bottom surface of the groove.

[0010] A slit recessed upward relative to other areas may be arranged on the lower surface of the fence portion outside a region connected to the upper end of the connecting portion.

[0011] The rear body may include a contact portion that extends downward from a lower end of the coupling portion and that contacts an inner surface of the rear body.

[0012] The contact portion may include a first region extending downward from a lower end of the joining portion, a second region extending downward from a lower end of the first region, and a bent portion disposed between the first region and the second region and contacting the inner surface of the rear body.

[0013] The contact portion may have elasticity such that an outer surface of the bent portion presses against an inner surface of the rear body.

[0014] The first region may be inclined so that the distance to the inner surface of the rear body becomes closer as it goes downward, and the second region may be inclined so that the distance to the inner surface of the rear body becomes farther as it goes downward.

[0015] The length of the protrusion in a first direction may be 0.4 mm to 0.6 mm shorter than the length of the coupling hole in the first direction, and the length of the protrusion in a second direction perpendicular to the first direction may be 0.2 mm to 0.3 mm shorter than the length of the coupling hole in the second direction. [Effects of the Invention]

[0016] In this embodiment, the assembly tolerances are compensated for by the movement of the second board to which the connector is coupled in multiple directions through the space between the protrusion and the coupling hole, which has the advantage that the rear body can be more easily coupled.

[0017] Furthermore, the contact structure between the shield member and the rear body has the advantage that the board module can be fixed more firmly within the rear body. [Brief explanation of the drawings]

The sealing member 280 may have a ring-shaped cross section and may be disposed between the outer circumferential surface of the lens barrel 210 and the inner surface of the front body 160. This may prevent foreign matter from entering the space within the camera module 10.

[0060] A flange 230 that protrudes outward from other regions may be formed on the outer circumferential surface of the lens barrel 210. When the lens module 200 is coupled to the front body 100, the lower surface of the flange 230 may be disposed on the upper surface of the barrel portion 163. This may allow the coupling region of the lens module 200 to be guided within the front body 100.

The grooves 325 may have a shape that is recessed more inward than other regions of the side surface of the second substrate 320. The grooves 325 may be formed on three of the side surfaces of the second substrate 320. As an example, when the side surfaces of the second substrate 320 include a first side surface, a second side surface facing the first side surface, a third side surface connecting the first side surface and the second side surface, and a fourth side surface facing the third side surface, the grooves 325 may be formed on each of the first to third side surfaces.

[0069] The protrusions 322 may have a shape that protrudes outward from the bottom surface of the groove 325. The protrusions 322 may be formed on three of the sides of the second substrate 320 corresponding to the formation area of ​​the groove 325. The protrusions 322 may have a rectangular cross-sectional shape, but the cross-sectional shape of the protrusions 322 is not limited thereto.

[0070] The shielding member 340 may fix the first substrate 310 and the second substrate 320. At least a portion of the shielding member 340 may be disposed between the first substrate 310 and the second substrate 320. The shielding member 340 may be coupled to the first substrate 310 and the second substrate 320. The first substrate 310 and the second substrate 320 may be spaced apart from each other with respect to the optical axis direction via the shielding member 340.

[0071] The shield member 340 may include a fence portion 342 , a coupling portion 350 , and a contact portion 356 .

[0072] The fence unit 342 may be disposed between the first substrate 310 and the second substrate 320. The first substrate 310 and the second substrate 320 may be spaced apart in the optical axis direction via the fence unit 342. An upper surface of the fence unit 342 may support a lower surface of the first substrate 310, and a lower surface of the fence unit 342 may support an upper surface of the second substrate 320.

[0073] A rib 343 protruding upward from other regions may be formed on the upper surface of the fence portion 342. The upper surface of the fence portion 342 may be coupled to the lower surface of the first substrate 310 via the rib 343 using surface mount technology (SMT).

[0074] A support part 346 may be disposed on a lower surface of the fence part 342, and may contact an upper surface of the second substrate 320. The support part 346 may be coupled to an upper surface of a corner region of the second substrate 320. The support part 346 may include a curved surface to correspond to the shape of the corner region of the second substrate 320.

[0075] The coupling part 350 may have a shape that protrudes downward from the lower surface of the fence part 342. The coupling part 350 may be disposed to overlap the second substrate 320 in a direction perpendicular to the optical axis direction. The coupling part 350 may be coupled to a groove 325 of the second substrate 320. As shown in FIG. 6, the length of the groove 325 may be longer than the length of the coupling part 350 in a first direction (X) perpendicular to the optical axis direction (Y).

[0076] The coupling portion 350 may include a coupling hole 353. The coupling hole 353 may have a shape that penetrates from the inner surface to the outer surface of the coupling portion 350. A protrusion 322 of the second substrate 320 may be coupled to the coupling hole 353. The protrusion 322 may penetrate the coupling hole 353 and at least a portion thereof may protrude outward from the coupling portion 350. The coupling hole 353 may have a rectangular cross-sectional shape. For example, the coupling hole 353 may include a first surface forming an inner surface, a second surface opposite the first surface, a third surface connecting the first surface and the second surface, and a fourth surface opposite the third surface and connecting the first surface and the second surface. Here, the first and second surfaces may have lengths shorter than the third and fourth surfaces.

[0077] The cross-sectional area of ​​the coupling hole 353 may be larger than the cross-sectional area of ​​the protrusion 322. At least a portion of the protrusion 322 may be spaced apart from the inner surface of the coupling hole 353. When the surface of the protrusion 322 facing the inner surface of the coupling hole 353 is defined as the outer surface, the outer surface of the protrusion 322 may include a region spaced apart from the inner surface of the coupling hole 353.

[0078] 6, the length L1 of the protrusion 322 in the first direction (X) may be smaller than the length L2 of the coupling hole 353 in the first direction (X). The length L1 of the protrusion 322 in the first direction (X) may be shorter than the length L2 of the coupling hole 353 in the first direction (X) by 0.4 mm to 0.6 mm.

[0079] Based on the second direction (Y) that is perpendicular to the first direction (X) and corresponds to the optical axis direction, the length L3 of the protrusion 322 in the second direction (Y) may be shorter than the length L4 of the coupling hole 353 in the second direction (Y). The length L3 of the protrusion 322 in the second direction (Y) may be shorter than the length L4 of the coupling hole 353 in the second direction (Y) by 0.2 mm to 0.3 mm.

[0080] The protrusion 322 may contact any one of the inner surfaces of the coupling hole 353. For example, the outer surface of the protrusion 322 may contact the third surface of the coupling hole 353 and be spaced apart from the first, second, and fourth surfaces.

[0081] 2, the rear body 110 according to this embodiment may be coupled to the rear surface of the front body 160 with the connector 390 coupled to the underside of the second board 320. The coupling of the rear body 110 may include a process of inserting the connector 390 into the connector outlet 119. In this case, if there is an assembly tolerance between the board module 300 and the front body 160 or an assembly tolerance of the board module 300 itself, it may be difficult to insert the connector 390 into the connector outlet 119, or the board module 300 may be damaged during the insertion process. However, according to this embodiment, the second board 320 coupled to the connector 390 can move a predetermined distance in multiple directions through the space between the coupling hole 353 in the shield member 340 and the protrusion 322 of the second board 320, thereby advantageously facilitating the coupling of the connector outlet 119 and the connector 390.

[0082] 6, a slit 354 may be formed in a region of the lower surface of the fence portion 342 connected to the upper end of the coupling portion 350, the slit 354 being recessed upward relative to other regions. The slit 354 may be disposed on both sides of the upper end of the coupling portion 350. The slit 354 may include a curved surface. The slit 354 allows the coupling portion 350 and the contact portion 356 to be easily bent relative to the fence portion 342.

[0083] The coupling portions 350 may be disposed at the lower ends of three of the lower surfaces of the fence portion 342, which has a rectangular cross section. In this case, the connection board may be disposed on the surface of the fence portion 342 where the coupling portions 350 are not disposed. The shielding member 340 may include a support plate 360 ​​that is bent inward from the lower end of the side of the fence portion 342 where the coupling portions 350 are not formed and supports the connection board. The connection board may be supported by the lower surface of the support plate 360.

[0084] The contact portion 356 may extend downward from a lower end of the coupling portion 350. At least a portion of the contact portion 356 may contact the inner surface of the rear body 110. The contact portion 356 may include a first region 367 extending downward from a lower end of the coupling portion 350 and a second region 368 extending downward from a lower end of the first region 367. The first region 367 may be inclined such that the distance to the inner surface of the rear body 110 decreases as the first region 367 extends downward. The second region 368 may be inclined such that the distance to the inner surface of the rear body 110 increases as the second region 368 extends downward. The first region 367 and the second region 368 may be arranged to form a predetermined angle.

[0085] A bent portion 369 may be formed between the first region 367 and the second region 368, the outer surface of which contacts the inner surface of the rear body 110. The bent portion 369 may be disposed to pressurize the inner surface of the rear body 110.

[0086] The contact portion 356 may have an outward elastic force in a direction in which it presses the inner surface of the rear body 110. In some cases, the coupling portion 350, together with the contact portion 356, may also have an outward elastic force based on the lower end of the fence portion 342. A protruding length of the bent portion 369 from a side surface of the second substrate 320 before the rear body 110 is coupled may be greater than a protruding length of the bent portion 369 from a side surface of the second substrate 320 after the rear body 110 is coupled. When the rear body 110 is coupled, the outer surface of the bent portion 369 may press the inner surface of the rear body 110 by elastic force.

[0087] According to the above structure, when the rear body 110 is assembled, the inner surface of the rear body 110 comes into contact with the bent portion 369, so that the assembly portion 350 can be assembled into the groove 325 of the second board 320. In addition, there is an advantage that the assembly state of the board module 300 within the rear body 110 can be maintained more firmly.

[0088] Meanwhile, the contact between the shield member 340 and the rear body 110 may provide a grounding structure for the board module 300 .
