[0028] The embodiments of this utility model are described below with reference to the accompanying drawings.

[0029] Figure 1 This is a perspective view showing an example configuration of camera module 1 according to this embodiment. Figure 2 It is shown Figure 1 A side view of an example configuration of one side surface of camera module 1 is shown, and Figure 3 It is shown when viewed from above. Figure 1 The top view shows a configuration example for camera module 1.

[0030] According to its appearance, camera module 1 includes a lens unit 3, a front housing 5 on which the lens unit 3 is mounted, a rear housing 7 assembled with the front housing 5, and a mounting connector 9. Camera module 1 is used in different orientations depending on its intended use. The following embodiments and examples will be described with reference to the horizontal direction HR57 and the vertical direction VT57, Z direction, X direction, and Y direction listed in each of the accompanying drawings. In the following embodiments, the surface facing upwards above the vertical direction VT57 may be referred to as the upper surface, and the surface facing downwards above the vertical direction VT57 may be referred to as the lower surface. In the following embodiments and examples, the descriptions of "forming" and "setting" include cases where components are integrally formed and cases where components are individually formed and subsequently bonded and welded. In the following embodiments and examples, the description of "interior" refers to the enclosed space side formed by assembling the front housing 5 and the rear housing 7 together. The description of "exterior" refers to the side not included in the space and is the released open space side.

[0031] When in Figure 2 When positioned in the indicated direction, the lens unit 3 is located at the upper part of the camera module 1. The lens unit 3 may, for example, have a shape in which multiple cylinders with different radii are connected to each other, and the radius of the upper cylinder may be larger than the radius of the lower cylinder. Threads are formed on the outer circumferential surface of the lower cylinder of the lens unit 3. For simplicity, the threads are omitted. The lens unit 3 has a lens 3A built into the upper part. The convex lens surface 3B of the lens 3A is exposed on the upper surface of the lens unit 3.

[0032] The front housing 5 is, for example, formed as a hollow quadrangular prism. The four corners of the upper surface of the front housing 5 are rounded. A hole 5X into which the lower cylinder of the lens unit 3 can be inserted is formed on the upper surface of the front housing 5. The threads engaged by the threads on the outer circumferential surface of the lower cylinder of the lens unit are formed on the inner circumferential surface of the hole. For the sake of simplicity, the threads are omitted. Therefore, the lens unit 3 is configured to be detachable from the front housing 5 by screwing the lower cylinder of the lens unit 3 into the hole 5X of the front housing 5.

[0033] The rear housing 7 is, for example, formed as a hollow tetrahedral prism. The four corners of the lower surface of the rear housing 7 are rounded. The rear housing 7 is assembled with the aforementioned front housing 5. The assembly of the rear housing 7 and the front housing 5 creates a space within the rear housing 7 and the front housing 5. The peripheral edge of the rear housing 7 includes the periphery of the end portion of the rear housing 7. The peripheral edge of the front housing 5 includes the periphery of the end portion of the front housing 5.

[0034] The width W5 of the front housing 5 in the direction perpendicular to the optical axis 3C of the lens 3A is greater than the width W7 of the rear housing 7. The difference between the width W5 of the front housing 5 and the width W7 of the rear housing 7 forms a third offset gap G57. Details will be described later.

[0035] A mounting connector 9, which can be connected to the connector 8 described later, is disposed on the lower surface of the rear housing 7 so as to extend in a direction parallel to the optical axis 3C of the lens 3A.

[0036] Figure 4 It is shown Figure 1 A partial cross-sectional view of a configuration example of camera module 1 shown. Figure 5 yes Figure 4 An enlarged view of the range R shown. Figure 5 The example shown depicts an enlarged view including the front housing 5, the rear housing 7, the adhesive 2, and the substrate 4. Figure 4 In the sectional view shown, section lines of some components may be omitted.

[0037] like Figure 4 As shown, when the peripheral edges of the front housing 5 and the rear housing 7 are assembled together, a space is formed internally by the front housing 5 and the rear housing 7. The peripheral edge of the front housing 5 is fixed to the peripheral edge of the rear housing 7 by an adhesive 2 applied between the peripheral edges of the front housing 5 and the rear housing 7. The adhesive 2 can be partially or completely cured by ultraviolet radiation. If active alignment, which will be described later, is performed before curing, the optical axis 3C of the lens 3A can be positioned at the image sensor 6, which will be described later.

[0038] The substrate 4 is housed inside the rear housing 7. For example, on the substrate 4, the image sensor 6 is disposed near the intersection of the optical axis 3C and the lens 3A of the lens unit 3 disposed on the front housing 5. A hole for mounting the mounting connector 9 is disposed in the lower surface of the rear housing 7. The mounting connector 9 and the drive device 10 are disposed on the lower surface of the substrate 4.

[0039] Connector 8 ensures electrical conduction between mounting connector 9 and substrate 4 by assembling with mounting connector 9. Drive unit 10 includes electronic circuitry for driving image sensor 6.

[0040] As in Figure 5 As shown in the range R, the peripheral edges of the front housing 5 and the rear housing 7 are bonded to the substrate 4 by adhesive 2.

[0041] like Figure 5 As shown, the stepped portion 7B is formed by cutting off the peripheral edge surface 7A of the rear housing 7, which is parallel to the horizontal direction HR57 and faces the front housing. The substrate 4 is placed on the stepped portion 7B and thus accommodated in the rear housing 7.

[0042] The stepped portion 7B is formed, for example, inside the peripheral edge of the rear housing 7. At least a portion of the stepped portion 7B forms a step in the peripheral edge of the rear housing 7 in a direction perpendicular to the thickness direction of the rear housing 7. The thickness direction of the rear housing 7 is also referred to as the horizontal direction or horizontal direction HR57. The thickness direction can also be referred to as the direction perpendicular to the optical axis direction of the lens 3A. The direction perpendicular to the thickness direction of the rear housing 7 corresponds to Figure 5 The vertical direction VT57 in the image. The vertical direction can also be referred to as the direction parallel to the optical axis 3C of lens 3A.

[0043] The stepped portion 7B is formed by a bottom surface 7C (a surface parallel to the horizontal direction HR57) and a lateral peripheral surface 7G (a surface parallel to the vertical direction VT57). The bottom surface 7C of the stepped portion 7B supports the peripheral edge of the substrate 4. The bottom surface 7C is the surface of the peripheral edge of the substrate 4 parallel to the horizontal direction HR57, and supports the bottom surface of the substrate 4 in the downward direction located in the vertical direction VT57. The lateral peripheral surface 7G of the stepped portion 7B supports the peripheral edge of the substrate 4. The lateral peripheral surface 7G of the stepped portion 7B supports the side surface of the substrate 4, which is the surface of the peripheral edge of the substrate 4 parallel to the vertical direction VT57. The substrate 4 is placed on the bottom surface 7C of the stepped portion 7B.

[0044] Adhesive 2 integrally bonds the peripheral edge surface 5A of the front housing 5, the peripheral edge of the substrate 4 on the bottom surface of the stepped portion 7B placed in the rear housing 7, and the peripheral edge surface 7A of the rear housing 7. Adhesive 2 also serves as a sealing material for sealing the space formed by the front housing 5 and the rear housing 7.

[0045] The peripheral edge surface 5A of the front housing is located at the peripheral edge of the front housing 5 and is parallel to the horizontal direction HR57. The peripheral edge of the substrate 4 is formed by the side surface 5E and the top surface 5D of the substrate 4. The side surface is parallel to the vertical direction VT57, and the top surface is part of the peripheral edge of the substrate 4, which is a surface of the peripheral edge of the substrate 4 that is parallel to the horizontal direction HR57. The peripheral edge surface 7A of the rear housing is located at the peripheral edge of the rear housing 7 and is parallel to the horizontal direction HR57. When the front housing 5 and the rear housing 7 are assembled together, the peripheral edge surface 5A of the front housing faces the peripheral edge surface 7A of the rear housing.

[0046] In this embodiment, the height H7 from the bottom surface 7C of the stepped portion 7B of the rear housing 7 to the peripheral edge surface 7A of the rear housing 7 is less than the height H4 from the bottom surface 7C of the stepped portion 7B to the substrate 4. The first biasing portion 7F is formed at the peripheral edge of the rear housing 7 by the difference between the height H7 of the stepped portion 7B and the height H4 to the upper surface of the substrate 4.

[0047] In this embodiment, with the rear housing 7 assembled with the front housing 5, a protrusion 5Z projecting from the front housing 5 toward the rear housing 7 is formed on at least a portion of the peripheral edge of the front housing 5. For example, an example is illustrated where the protrusion 5Z is formed over the entire circumference of the peripheral edge of the front housing 5. The protrusion 5Z is not limited to the presented example; for example, the protrusion 5Z can be formed by cutting off the entire circumference or a portion of the circumference of the outer side of the peripheral edge of the front housing 5, the protrusion 5Z can be formed by cutting off the entire circumference or a portion of the circumference of the inner side of the peripheral edge of the front housing 5, or a combination thereof.

[0048] The protrusion 5Z protrudes further than the upper surface 5B of the adhesive 2 in the vertical direction VT57. When the rear housing 7 and the front housing 5 are assembled together, the protrusion 5Z protrudes further towards the peripheral edge surface 7A of the rear housing than the upper surface 5B of the adhesive 2. The height H5 of the protrusion 5Z is the distance from the upper surface 5B of the adhesive 2 to the peripheral edge surface 5A of the front housing in the vertical direction VT57. The second offset portion 5C is formed at the height H5 at the peripheral edge of the front housing 5.

[0049] The width W5 of the front housing 5 in the horizontal direction HR57 is formed to be greater than the width W7 of the rear housing 7 in the horizontal direction HR57. For example... Figure 1 As shown, the width W5 is located on the outer periphery of the front housing 5 in the horizontal direction HR57, and is the distance from the left surface to the right surface. Figure 1As shown, the width W7 is located on the outer periphery of the rear housing 7 in the horizontal direction HR57, and is the distance from the left side surface to the right side surface. The left side surface and the right side surface can also be referred to as one side surface and another side surface. Figure 5 As shown, the difference in the horizontal direction HR57 between the left side surface 5L of the front housing 5 and the left side surface 7L of the rear housing 7 corresponds to the third offset gap G57. This difference is also described as a predetermined width. In this embodiment, the third offset portion 7D is constructed by a third offset gap G57 having a predetermined length.

[0050] The adhesive 2 contacts the front housing peripheral edge surface 5A formed at the peripheral edge of the front housing 5, the side surface 5E which is part of the peripheral edge of the substrate 4, the upper surface 5D which is part of the peripheral edge of the substrate 4, and the rear housing peripheral edge surface 7A formed at the peripheral edge of the rear housing 7.

[0051] The second biasing portion 5C at the peripheral edge of the front housing 5 includes the aforementioned peripheral edge surface 5A of the front housing and an inner surface 5C1 located inside the peripheral edge of the front housing 5, and the peripheral edge surface 5A and the inner surface 5C1 are in contact with the adhesive 2. The inner surface 5C1 is the circumferential surface inside the peripheral edge of the front housing 5 and is a surface parallel to the vertical direction VT57. The adhesive 2 contacts the peripheral edge surface 5A of the front housing 5 formed at the peripheral edge of the front housing 5, the side surface 5E which is part of the peripheral edge of the substrate 4, the upper surface 5D which is part of the peripheral edge of the substrate 4, the peripheral edge surface 7A of the rear housing 7 formed at the peripheral edge of the rear housing 7, and the inner surface 5C1 which constitutes the inner circumferential surface of the peripheral edge of the front housing 5.

[0052] The camera module 1 according to this embodiment has the above configuration. An example of the process for assembling the camera module 1 according to this embodiment will be disclosed. First, the lens unit 3 is screwed into the front housing 5 along the threads (as shown). The substrate 4 is mounted on the stepped portion 7B of the rear housing 7. Adhesive 2 is applied to the peripheral edge surface 7A of the peripheral edge portion of the rear housing 7, including the peripheral edge of the substrate 4. Figure 6 As shown, the peripheral edges of the front housing 5 and the rear housing 7 are assembled together, and the front housing 5 is attached to the rear housing 7. The image sensor 6 is mounted near the position where the optical axis 3C of the lens 3A of the lens unit 3 disposed in the front housing 5 intersects with the substrate 4.

[0053] Next, perform active alignment. For example... Figure 6As shown, the front housing 5 swings relative to the rear housing 7 in the Z direction parallel to the optical axis 3C, and in the X and Y directions perpendicular to the Z direction, and rotates in the X and Y directions. Thus, the orientation of the front housing 5 relative to the rear housing 7 is adjusted in the Z direction parallel to the optical axis 3C. The optical axis 3C is adjusted such that the optical axis 3C of the lens 3A of the lens unit 3 passes through, for example, the center or near the center of the image sensor 6 disposed on the substrate 4. In other words, the relative position of the front housing 5 relative to the rear housing 7 is adjusted by swinging the front housing 5 or the rear housing 7 in the X and Y directions.

[0054] The adhesive 2 is partially or completely cured by ultraviolet light emitted from the ultraviolet irradiation device 100, and thus the orientation of the optical axis 3C of the lens 3A of the lens unit 3 is fixed relative to the image sensor 6 disposed on the substrate 4 of the rear housing 7.

[0055] Figure 7 This is a partial cross-sectional view showing an example of performing the above-described active alignment. Figure 8 In the completion Figure 7 The enlarged view of the range R of camera module 1 under active alignment is shown.

[0056] Even when the rear housing 7 swings relative to the front housing 5 as shown by the dashed line, the rear housing 7 will not protrude from the width W5 of the front housing 5 due to active alignment. That is, due to the third offset gap G57 with a specified width, the rear housing 7, which is in the horizontal direction HR57, is aligned as shown by the presence of the third offset portion 7D. Figure 8 It is housed within the width W5 of the front housing 5 as shown.

[0057] Figures 9 to 11 This diagram illustrates a specific example of the stepped portion 7B described above. The common configuration in each example is disclosed below. The bottom surface 7C of the stepped portion 7B is the peripheral edge of the substrate 4 and supports the bottom surface of the substrate 4. The bottom surface 7C contacts, for example, the lower surface of the substrate 4 where the image sensor 6 is not disposed. The lateral circumferential surface 7G of the stepped portion 7B is the peripheral edge of the substrate 4 and supports at least a portion of the lateral surface of the substrate 4. The end portion of the bottom surface 7C contacts the lateral circumferential surface 7G. Therefore, the substrate 4 is supported by both the bottom surface 7C and the lateral circumferential surface 7G. This is the common configuration in each example.

[0058] As a specific example of the step portion 7B, the first step portion 7B1, the second step portion 7B2, and the third step portion 7B3 will be disclosed below. In this embodiment and specific example, when describing the step portion 7B, the step portion 7B includes the first step portion 7B1, the second step portion 7B2, and the third step portion 7B3. In this embodiment and specific example, when describing the bottom surface 7C, the bottom surface 7C includes the bottom surface 7C1, the bottom surface 7C2, and the bottom surface 7C3, which will be described later.

[0059] Figure 9 The first stepped portion 7B1 shown is formed in a rectangular shape along the interior of the peripheral edge surface 7A of the rear housing, above the entire peripheral edge. The first stepped portion 7B1 includes a bottom surface 7C1 and a lateral circumferential surface 7G. The bottom surface 7C1 is a rectangular surface parallel to the horizontal direction HR57 and is constructed of an upward-facing plane located in the vertical direction VT57. The first stepped portion 7B1 supports the bottom and side surfaces of the substrate 4 along the entire inner periphery of the peripheral edge surface 7A of the rear housing.

[0060] Figure 10 The second step portion 7B2 shown is formed as a column extending in the vertical direction VT57 along the interior of the peripheral edge surface 7A of the rear housing. The second step portion 7B2 includes a bottom surface 7C2 and a lateral circumferential surface 7G. The bottom surface 7C2 is a columnar surface parallel to the horizontal direction HR57 and is constructed from a plane in the upward direction located in the vertical direction VT57. The shape of the bottom surface 7C2 is not limited to a rectangle and can be, for example, circular. The second step portion 7B2 supports the bottom surface of the substrate 4 along the inner portion of the peripheral edge surface 7A of the rear housing. The lateral circumferential surface 7G has a shape similar to... Figure 9 The same configuration is shown for the lateral circumferential surface 7G. The location of the second step portion 7B2 is unrestricted, and the second step portion 7B2 can be located at a corner of the rear housing 7 in the peripheral edge surface 7A of the rear housing 7. Using this configuration, with... Figure 9 Compared to the configuration shown, the number of components constituting the step portion 7B2 can be reduced. Figure 9 Compared to the configuration shown, it achieves overall weight reduction.

[0061] Figure 11 The third step portion 7B3 shown is formed in an L-shape extending in the vertical direction VT57 within the peripheral edge surface 7A of the rear housing, and this shape is the shape along the corner of the rear housing 7. The third step portion 7B3 is partially formed around the corner of the rear housing 7. The third step portion 7B3 includes a bottom surface 7C3 and a lateral circumferential surface 7G. The bottom surface 7C3 is a cylindrical surface parallel to the horizontal direction HR57 and is constructed from a plane in the upward direction located in the vertical direction VT57. The lateral circumferential surface 7G has a shape similar to... Figure 9The same configuration as the lateral circumferential surface 7G shown. The third step portion 7B3 supports the bottom surface of the base plate 4 along the inner portion of the peripheral edge surface 7A of the rear housing. Using this configuration, with... Figure 9 Compared to the configuration shown, the number of components constituting the step portion 7B3 can be reduced, and therefore... Figure 9 Compared to the configuration shown, this configuration achieves overall weight reduction. Furthermore, the third step portion 7B3 supports the corner of the substrate 4 along the inner side of the peripheral edge surface 7A of the rear housing. Using this configuration, the substrate 4... Figure 10 The configuration shown is more stable.

[0062] According to this embodiment, the camera module 1 is a camera module 1 provided with a front housing 5 on which a lens unit 3 is mounted and a rear housing 7 assembled with the front housing 5. The camera module 1 is provided with: a stepped portion 7B, which is a step formed inside the peripheral edge of the rear housing and formed in a direction perpendicular to the thickness direction of the rear housing 7; a substrate 4, which is placed on the bottom surface 7C of the stepped portion 7B; and an adhesive 2, which integrally bonds the peripheral edge surface 5A of the front housing formed on the peripheral edge of the front housing 5, the peripheral edge of the substrate 4 placed on the bottom surface of the stepped portion 7B in the rear housing 7, and the peripheral edge surface 7A of the rear housing formed on the peripheral edge of the rear housing 7, wherein the height from the bottom surface 7C of the stepped portion 7B to the peripheral edge surface 7A of the rear housing is less than the height from the bottom surface of the stepped portion 7B to the upper surface of the substrate 4.

[0063] This configuration improves resistance to forces applied horizontally relative to the peripheral edges of the front housing 5 and the rear housing 7.

[0064] According to this embodiment, the camera module 1 is provided with a protrusion 5Z that protrudes further toward the peripheral edge surface 7A of the rear housing than the upper surface 2B of the adhesive 2. This configuration can further improve resistance to forces applied in the horizontal direction relative to the peripheral edges of the front housing 5 and the rear housing 7.

[0065] In the camera module 1 according to this embodiment, the width W5 (the distance from one side surface to the other in the thickness direction on the outer periphery of the front housing 5) is greater than the width W7 (the distance from one side surface to the other in the outer periphery of the rear housing 7). With this configuration, even when active alignment is performed to focus the lens 3A of the lens unit 3, the front housing 5 and the rear housing 7 can ultimately be fixed with the rear housing 7 housed inside the front housing 5.

[0066] In the camera module 1 according to this embodiment, the peripheral edge of the substrate 4 is formed by a side surface and a top surface of the substrate 4. The side surface is a surface parallel to a vertical direction perpendicular to the thickness direction, and the top surface is a surface of the peripheral edge of the substrate 4 that is horizontal to the thickness direction. The adhesive 2 contacts the front housing peripheral edge surface 5A formed at the peripheral edge of the front housing 5, the side surface 5E which is part of the peripheral edge of the substrate 4, the top surface 5D which is part of the peripheral edge of the substrate 4, and the rear housing peripheral edge surface 7A formed at the peripheral edge of the rear housing 7. With this configuration, the front housing 5, the rear housing 7, and the substrate 4 are simultaneously and integrally bonded by the adhesive 2, thus simplifying the process. Furthermore, the cost of manufacturing the camera module 1 can be reduced.

[0067] In the camera module 1 according to this embodiment, the second biasing portion 5C is formed by a front housing peripheral edge surface 5A and an inner surface 5C1. The front housing peripheral edge surface is a surface located at the peripheral edge of the front housing 5 and is parallel to the thickness direction. The inner surface is the inner side of the front housing 5 within the peripheral edge of the front housing 5. The front housing peripheral edge surface 5A and the inner surface 5C1 are in contact with the adhesive 2. This configuration can further improve resistance to forces applied in the horizontal direction relative to the peripheral edges of the rear housing 7 and the front housing 5.

[0068] It should be noted that this utility model is not limited to the above-described embodiments, but includes various modifications and equivalent configurations within the scope of the appended patent claims. For example, although the above embodiments have been described in detail for the purpose of describing this utility model in an easily understandable manner, this utility model is not necessarily limited to having all of the described configurations. Furthermore, each element described in parallel in this embodiment may be an aspect in which at least one element is connected in series with another element.
