Technical Field

[0001] This disclosure relates to camera modules. Background Technology

[0002] Driven by the trend towards thinner portable electronic devices, such as mobile phones that include camera modules, the size of components mounted on electronic devices is being miniaturized.

[0003] Portable smartphone camera modules for video recording can use high-performance camera modules, such as those used in vehicles to enable cutting-edge Advanced Driver Assistance Systems (ADAS) for autonomous driving functions.

[0004] However, as camera modules become smaller and have higher resolutions, the risk of damage to camera modules due to external forces also increases.

[0005] The above information is presented as background information and is intended to aid in understanding this disclosure. No determination or assertion is made as to whether any of the above content can be used as prior art with respect to this disclosure. Utility Model Content

[0047] Figure 1 This is an exploded perspective view of camera module 1 according to the embodiment.

[0048] Reference Figure 1 According to the embodiments, the camera module 1 may include a lens barrel 10, a housing 20, an image sensor 30, a substrate 40, and a reinforcing member 50.

[0049] The lens barrel 10 can house at least one lens. The lens barrel 10 can have a hollow cylindrical shape, allowing at least one lens for photographing the subject to be housed within it. When multiple lenses are used, they can be mounted in the lens barrel 10 along the optical axis OA (z-axis in the figures). The multiple lenses can be arranged in a desired number based on the design of the lens barrel 10, and each lens can have optical properties such as the same or different refractive indices.

[0050] The housing 20 can house the lens barrel 10. For example, the housing 20 can have an open structure at the top and bottom. The housing 20 can protect the internal components of the camera module 1. In addition, the housing 20 can shield electromagnetic waves generated from the camera module 1 so that the electromagnetic waves do not affect other electronic components. The substrate 40 on which the image sensor 30 is mounted can be located at the bottom of the housing 20.

[0051] Image sensor 30 can be disposed on one side of lens barrel 10 in the direction of optical axis OA. Image sensor 30 can convert incident light passing through the lens into an electrical signal. For example, image sensor 30 can be a charge-coupled device (CCD), complementary metal-oxide-semiconductor (CMOS), etc. The electrical signal converted by image sensor 30 can be output as an image through the display unit of an electronic device such as a smartphone. Image sensor 30 can be mounted on substrate 40.

[0052] Image sensor 30 can be electrically connected to substrate 40. For example, image sensor 30 can be directly connected to substrate 40 via wire bonding or the like. One end of the wire can be attached to the connection terminal of image sensor 30, and the other end of the wire can be attached to the connection terminal of substrate 40.

[0053] One end of the substrate 40 may have a structure extending outside the housing 20 for connection to external circuitry. The substrate 40 may be a flexible printed circuit board (FPCB) or the like. For example, the substrate 40 may be any of, but is not limited to, flexible resin substrates such as polyimide, rigid-flex PCBs (RFPCBs), and double-layer FPCBs.

[0054] The substrate 40 may have an opening 41 in its central region. The opening 41 is configured to penetrate both surfaces of the substrate 40. Therefore, spaces located on the two surfaces of the substrate 40 in the direction of the optical axis OA can be connected to each other through the opening 41. The opening 41 may have a shape corresponding to the shape of the image sensor 30. The area of ​​the opening 41 may be set to be equal to or greater than the area of ​​the image sensor 30. Therefore, the image sensor 30 can be disposed in the opening 41.

[0055] After the image sensor 30 is placed in the opening 41 of the substrate 40, the image sensor 30 and the substrate 40 are electrically connected, thereby maximizing space efficiency and reducing the size of the camera module 1.

[0056] The reinforcing member 50 can be disposed on one side of the substrate 40. The reinforcing member 50 can also be disposed on the opposite side of the substrate 40, opposite to the side where the lens barrel 10 is located. In the optical axis OA direction, the reinforcing member 50 can be disposed below the substrate 40. The reinforcing member 50 can be attached to the substrate 40. The reinforcing member 50 can support the substrate 40 and prevent the substrate 40 from deforming or being damaged due to external forces.

[0057] Figure 2 This is a diagram of the substrate 40 and the reinforcing member 50 viewed from top to bottom along the optical axis OA, where light propagates along the optical axis OA. Figure 3 This is a top view of the reinforcing member 50, and Figure 4 It is along Figure 3 A cross-sectional view taken from line A-A'.

[0058] Reference Figures 2 to 4 The rigid reinforcing portion 500 may be located on the reinforcing member 50. For example, the rigid reinforcing portion 500 may be configured to be recessed downward from the adjacent region. That is, when viewed from top to bottom in the optical axis OA direction, the rigid reinforcing portion 500 may be configured to be more recessed than the adjacent region in the opposite direction of the substrate 40. Additionally, when viewed from bottom to top in the optical axis OA direction, the rigid reinforcing portion 500 may be configured to be more protruding than the adjacent region in the opposite direction of the substrate 40. The reinforcing member 50 may include a first surface 511 and a second surface 512. The first surface 511 may face the substrate 40. The second surface 512 may be located on the opposite side of the side where the substrate 40 is located. Furthermore, the rigid reinforcing portion 500 may be recessed in the first surface 511 and protrude in the second surface 512.

[0059] For example, the reinforcing member 50 can be formed from a metallic material such as SUS. Additionally, the rigid reinforcing portion 500 can be formed by a stamping process. Therefore, the thickness of the reinforcing member 50 in the optical axis OA direction can correspond to the thickness of the rigid reinforcing portion 500 and the thickness of other regions besides the rigid reinforcing portion 500.

[0060] The reinforcing member 50 may include a first region 51 and a second region 52. The second region 52 may be located within the first region 51. That is, the first region 51 may be located on the periphery of the second region 52. For example, a first side 521, a second side 522, a third side 523, and a fourth side 524 may be located at the boundary between the first region 51 and the second region 52. The two ends of the first side 521 are respectively connected to one end of the second side 522 and one end of the fourth side 524. The two ends of the third side 523 are respectively connected to the other ends of the second side 522 and the fourth side 524. The first side 521 faces the third side 523. The second side 522 faces the fourth side 524.

[0061] If the substrate 40 is disposed on the reinforcing member 50, the first region 51 of the first surface 511 can face one surface of the substrate 40 in the optical axis OA direction. If the substrate 40 is disposed on the reinforcing member 50, the second region 52 of the first surface 511 can face the opening 41 in the optical axis OA direction. Therefore, when the image sensor 30 is not present, the second region 52 of the first surface 511 can be exposed through the opening 41. When the image sensor 30 is connected to the substrate 40, the image sensor 30 can be disposed on the second region 52 of the first surface 511.

[0062] The rigid reinforcing portion 500 may be located in the second region 52. The rigid reinforcing portion 500 may include a plurality of rigid reinforcing lines 501. Each of the rigid reinforcing lines 501 may be configured to be recessed downward from the adjacent region. That is, when viewed from top to bottom on the optical axis OA, the rigid reinforcing line 501 may be configured to be more recessed than the adjacent region in the opposite direction of the substrate 40. In addition, when viewed from bottom to top on the optical axis OA, the rigid reinforcing line 501 may be configured to be more prominent than the adjacent region in the opposite direction of the substrate 40.

[0063] Each of the rigid reinforcing lines 501 can have a straight structure. Multiple rigid reinforcing lines 501 can be positioned to intersect each other at at least one point. For example, the longitudinal direction of each of the rigid reinforcing lines 501 can be configured to pass through the central region of the second region 52 and towards a corner of the second region 52. That is, the longitudinal direction of each of the rigid reinforcing lines 501 can extend from the corner where the first side 521 and the fourth side 524 meet to the corner where the second side 522 and the third side 523 meet. Additionally, the longitudinal direction of the rigid reinforcing line 501 can extend from the corner where the first side 521 and the second side 522 meet to the corner where the third side 523 and the fourth side 524 meet. Two rigid reinforcing lines 501 can intersect each other in the central region of the second region 52.

[0064] Furthermore, the two ends of each of the rigid reinforcing lines 501 can be positioned adjacent to the corners of the second region 52. That is, the length of each of the rigid reinforcing lines 501 can correspond to the length of the distance between the corners of the second region 52 facing each other in the diagonal direction passing through the central region of the second region 52.

[0065] The rigid reinforcement portion 500 can enhance the rigidity of the reinforcing member 50.

[0066] The rigid reinforcement portion 500 can reduce the deformation of the shape of the reinforcing member 50 caused by forces that cause deformation or bending. Therefore, when a force is applied to the substrate 40 or the image sensor 30 in the optical axis OA direction, the shape deformation of the second region 52 and the image sensor 30 disposed on the second region 52 can be minimized by the reinforcing member 50 having the rigid reinforcement portion 500. Thus, the image sensor 30 can be prevented from bending and being damaged by external forces.

[0067] Figure 5 This is a cross-sectional view of the reinforcing member 50a according to another embodiment.

[0068] Reference Figure 5 The rigid reinforcing portion 500a may be located on the reinforcing member 50a. For example, the rigid reinforcing portion 500a may be configured to protrude upward from the adjacent region. That is, when viewed from top to bottom in the optical axis OA direction, the rigid reinforcing portion 500a may be configured to protrude more towards the substrate 40 than the adjacent region. Additionally, when viewed from bottom to top in the optical axis OA direction, the rigid reinforcing portion 500a may be configured to be more recessed towards the substrate 40 than the adjacent region. The reinforcing member 50a may include a first surface 511a and a second surface 512a. The first surface 511a may face the substrate 40. The second surface 512a may be located on the opposite side of the side where the substrate 40 is located. The rigid reinforcing portion 500a may protrude from the first surface 511a and be recessed into the second surface 512a.

[0069] For example, the reinforcing member 50a can be formed from a metallic material such as SUS. Similarly, the rigid reinforcing portion 500a can be formed by a stamping process. Therefore, the thickness of the reinforcing member 50a in the optical axis OA direction can correspond to the thickness of the rigid reinforcing portion 500a and the thickness of the region excluding the rigid reinforcing portion 500a.

[0070] Figure 6 This is a top view of the reinforcing member 50b according to another embodiment.

[0071] Reference Figure 6 The rigid reinforcing portion 500b can be located on the reinforcing member 50b. The reinforcing member 50b may include a first region 51b and a second region 52b. The second region 52b can be located within the first region 51b. That is, the first region 51b can be located on the periphery of the second region 52b. For example, the first side 521b, the second side 522b, the third side 523b, and the fourth side 524b can be located at the boundary between the first region 51b and the second region 52b. The two ends of the first side 521b are respectively connected to one end of the second side 522b and one end of the fourth side 524b. The two ends of the third side 523b are respectively connected to the other ends of the second side 522b and the fourth side 524b. The first side 521b faces the third side 523b. The second side 522b faces the fourth side 524b.

[0072] If the substrate 40 is disposed on the reinforcing member 50b, the first region 51b may face a surface of the substrate 40 in the optical axis OA direction. If the substrate 40 is disposed on the reinforcing member 50b, the second region 52b may face the opening 41 in the optical axis OA direction. Therefore, when the image sensor 30 is not present, the second region 52b may be exposed through the opening 41. When the image sensor 30 is connected to the substrate 40, the image sensor 30 may be disposed on the second region 52b.

[0073] The rigid reinforcement portion 500b may be located in the second region 52b. The rigid reinforcement portion 500b may include multiple rigid reinforcement lines 501b.

[0074] The rigid reinforcing line 501b can have a straight structure. Multiple rigid reinforcing lines 501b can be positioned to intersect each other at at least one point. For example, the longitudinal direction of the rigid reinforcing line 501b can be parallel to one side of the second region 52b. That is, the longitudinal direction of the rigid reinforcing line 501b can be parallel to the first side 521b. Alternatively, the longitudinal direction of the rigid reinforcing line 501b can be parallel to the second side 522b. Furthermore, the rigid reinforcing line 501b can pass through the central region of the second region 52b. Additionally, two rigid reinforcing lines 501b can intersect each other in the central region of the second region 52b.

[0075] Furthermore, both ends of the rigid reinforcing line 501b can be positioned adjacent to one side of the second region 52b. That is, the length of the rigid reinforcing line 501b can correspond to the length of one side of the second region 52b parallel to the rigid reinforcing line 501b.

[0076] With the above Figures 2 to 4 Similar to or the same as described above, the rigid reinforcing portion 500b can be recessed into the first surface 511 and can protrude from the second surface 512. Additionally, as described above... Figure 5 Similar to or the same situation described in the text, the rigid reinforcement portion 500b can protrude from the first surface 511a and be recessed into the second surface 512a.

[0077] Figure 7 This is a top view of the reinforcing member 50c according to another embodiment.

[0078] Reference Figure 7 The rigid reinforcing portion 500c can be located on the reinforcing member 50c. The reinforcing member 50c may include a first region 51c and a second region 52c. The second region 52c can be located within the first region 51c. That is, the first region 51c can be located on the periphery of the second region 52c. For example, the first side 521c, the second side 522c, the third side 523c, and the fourth side 524c can be located at the boundary between the first region 51c and the second region 52c. The two ends of the first side 521c are respectively connected to one end of the second side 522c and one end of the fourth side 524c. The two ends of the third side 523c are respectively connected to the other ends of the second side 522c and the fourth side 524c. The first side 521c faces the third side 523c. The second side 522c faces the fourth side 524c.

[0079] If the substrate 40 is disposed on the reinforcing member 50c, the first region 51c may face a surface of the substrate 40 in the optical axis OA direction. If the substrate 40 is disposed on the reinforcing member 50c, the second region 52c may face the opening 41 in the optical axis OA direction. Therefore, when the image sensor 30 is not present, the second region 52c may be exposed through the opening 41. When the image sensor 30 is connected to the substrate 40, the image sensor 30 may be disposed on the second region 52c.

[0080] The rigid reinforcement portion 500c may be located in the second region 52c. The rigid reinforcement portion 500c may include multiple rigid reinforcement lines 501c and 502c.

[0081] The rigid reinforcing lines 501c and 502c can have a straight structure. Multiple rigid reinforcing lines 501c and 502c can be positioned to intersect each other at at least one point.

[0082] The rigid reinforcing lines 501c and 502c may include a first rigid reinforcing line 501c and a second rigid reinforcing line 502c.

[0083] The longitudinal direction of the first rigid reinforcing line 501c can be configured to pass through the central region of the second region 52c and point towards the corner of the second region 52c. That is, the longitudinal direction of the first rigid reinforcing line 501c can extend from the corner where the first side 521c and the fourth side 524c meet to the corner where the second side 522c and the third side 523c meet. Furthermore, the longitudinal direction of the first rigid reinforcing line 501c can extend from the corner where the first side 521c and the second side 522c meet to the corner where the third side 523c and the fourth side 524c meet. Additionally, the two first rigid reinforcing lines 501c can intersect each other in the central region of the second region 52c.

[0084] Furthermore, the two ends of the first rigid reinforcing line 501c can be positioned adjacent to the corners of the second region 52c. That is, the length of the first rigid reinforcing line 501c can correspond to the length of the distance between the corners of the second region 52c facing each other in the diagonal direction passing through the central region of the second region 52c.

[0085] The longitudinal direction of the second rigid reinforcing line 502c can be parallel to one side of the second region 52c. That is, the longitudinal direction of the second rigid reinforcing line 502c can be parallel to the first side 521c. Alternatively, the longitudinal direction of the second rigid reinforcing line 502c can be parallel to the second side 522c. Furthermore, the second rigid reinforcing line 502c can pass through the central region of the second region 52c. Additionally, the two second rigid reinforcing lines 502c can intersect each other in the central region of the second region 52c.

[0086] Furthermore, the two ends of the second rigid reinforcing line 502c can be positioned adjacent to one side of the second region 52c. That is, the length of the second rigid reinforcing line 502c can correspond to the length of one side of the second region 52c parallel to the second rigid reinforcing line 502c.

[0087] With the above Figures 2 to 4 Similar to or the same as described above, the rigid reinforcement portion 500c can be recessed into the first surface 511 and protrude from the second surface 512.

The second region 52f can be located within the first region 51f. That is, the first region 51f can be located on the periphery of the second region 52f. For example, the first side 521f, the second side 522f, the third side 523f, and the fourth side 524f can be located at the boundary between the first region 51f and the second region 52f. The two ends of the first side 521f are respectively connected to one end of the second side 522f and one end of the fourth side 524f.

If the substrate 40 is disposed on the reinforcing member 50f, the second region 52f can face the opening 41 in the optical axis OA direction. Therefore, when the image sensor 30 is not present, the second region 52f can be exposed through the opening 41. When the image sensor 30 is connected to the substrate 40, the image sensor 30 can be disposed on the second region 52f.
