FIG. 7 is a rear perspective view of the in-vehicle camera 100 according to the embodiment. FIG. 8 is an exploded perspective view of the in-vehicle camera 100 according to the embodiment. FIG. 9 is a top view of the in-vehicle camera 100 according to the embodiment. FIG. 10 is a cross-sectional view taken along line I-I of FIG. 9. A coordinate system including the X-axis along one side of the in-vehicle camera 100, the Y-axis orthogonal to the X-axis and along the other side of the in-vehicle camera 100, and the Z-axis orthogonal to the X-axis and the Y-axis and along the height direction of the in-vehicle camera 100 is defined and utilized in the following description.

[0015] The in-vehicle camera 100 of the present embodiment includes a cap 10, a ring member 20, a lens unit 30, a circuit board 40, an imaging element 50, a housing 60, a shield 70, and a resin member 90. The cap 10 is attached to the ring member 20 and is a member that protects the lens unit 30. In FIGS. 9 and 10, the illustration of the cap 10 is omitted.

[0016] The ring member 20 is composed of a flat plate-shaped member with a rectangular ring shape in plan view, and is welded to the lens unit 30 and the housing 60 by laser welding. The inner peripheral surface of the ring member 20 faces the outer peripheral surface of a first cylindrical portion 31 (to be described later) that constitutes the lens barrel of the lens unit 30. The inner diameter of the ring member 20 has a length that allows the insertion of the first cylindrical portion 31 (to be described later) of the lens unit 30.

[0017] The ring member 20 can be formed of a first resin. Thereby, the ring member 20 can be easily and inexpensively formed.

[0018] The lens unit 30 includes a first cylindrical portion 31 that constitutes a cylindrical lens barrel, and at least one lens that is accommodated inside the first cylindrical portion 31 and is disposed on the optical axis L (an axis extending in a direction perpendicular to the plane of FIG. 9 and along the Z-axis). The first cylindrical portion 31 is cylindrical and holds, for example, a lens group composed of a plurality of lenses inside. In the lens group, each lens is arranged with their respective optical axes L aligned, and constitutes a lens group used for imaging inside and outside the vehicle body of the vehicle V.

[0019] Furthermore, the lens unit 30 has a flange portion 32 that is disposed outside the first cylindrical portion 31 so as to extend outward with respect to the optical axis L over the entire circumference around the optical axis L. The flange portion 32 has a first flange surface 32a facing the ring member 20, a second flange surface 32b that is opposite to the first flange surface 32a and is located in the internal space of a large-diameter cylindrical portion 61 (to be described later) of the housing 60, and a flange end surface 32c that connects the first flange surface 32a and the second flange surface 32b.

[0020] At least the flange portion 32 of the lens unit 30 can be formed of a second resin. The entire lens unit 30 may be formed of the second resin. Thereby, the lens unit 30 can be easily and inexpensively formed.

[0021] The circuit board 40 is disposed in the internal space of the housing 60 and has a first surface 40a, a second surface 40b opposite to the first surface 40a, and an end surface 40c disposed between the first surface 40a and the second surface 40b. However, two or more circuit boards may be provided.

[0022] In a plan view of the circuit board 40 (a shape viewed in the direction of the optical axis L and along the Z axis, the same applies hereinafter), the circuit board 40 has a first shape including at least a first side 41, a second side 42, a third side 43, and a fourth side 44. The first shape is, for example, a first rectangular shape. Further, the end surface 40c of the circuit board 40 includes at least a first end surface 40c1 corresponding to the first side 41, a second end surface 40c2 corresponding to the second side 42, a third end surface 40c3 corresponding to the third side 43, and a fourth end surface 40c4 corresponding to the fourth side 44.

[0023] The imaging element 50 is disposed on the first surface 40a of the circuit board 40 and on the optical axis L of at least one lens of the lens unit 30. The imaging element 50 is electrically connected to the circuit of the circuit board 40, and by guiding external light to the imaging element 50, the imaging element 50 can capture an image.

[0024] The housing 60 is a cylindrical member having an internal space, supports the lens unit 30, and serves to accommodate at least the circuit board 40 and the imaging element 50. The housing 60 has a large-diameter cylindrical portion 61 having a second cylindrical shape along the optical axis L and a small-diameter cylindrical portion 62 along the optical axis L. The large-diameter cylindrical portion 61 constituting the second cylindrical portion has a larger cross-sectional area than the small-diameter cylindrical portion 62, and both have a rectangular cross-section. The large-diameter cylindrical portion 61 houses at least the circuit board 40 and the imaging element 50 inside. The small-diameter cylindrical portion 62 houses a connector 80 (described later) that secures electrical connection with the outside of the in-vehicle camera 100 exclusively. The large-diameter cylindrical portion 61 and the small-diameter cylindrical portion 62 can be integrally formed by a resin described later, but an individual large-diameter cylindrical portion 61 and a small-diameter cylindrical portion 62 prepared in advance may be joined by methods such as welding or screwing. Note that the housing 60 is a rectangular cylinder in the present embodiment, but is not limited thereto, and may be a cylindrical shape of a polygon other than a rectangle, a circular or elliptical cylinder, or a cylinder of other shapes.

[0025] The large-diameter cylindrical portion 61 has a first end portion 63 and a second end portion 64 that is opposite to the first end portion 63 and is disposed at a position farther from the first end portion 63 than the first end portion 63 in the direction of the optical axis L with respect to the lens unit 30.

[0026] At least the first end portion 63 of the housing 60 can be formed by the third resin. The entire housing 60 may be formed by the third resin. Thereby, the housing 60 can be easily and inexpensively formed.

[0027] As shown in FIG. 10, the housing 60 includes a connector 80 disposed across the inside and outside of the housing 60 on the bottom surface facing the circuit board 40. The connector 80 includes at least a first terminal 81 and a second terminal 82 that electrically connect the inside and outside of the housing 60, and the first terminal 81 and the second terminal 82 are electrically connected to the circuit of the circuit board 40.

[0028] The metal shield 70 is disposed in the internal space of the housing 60 so as to surround the circuit board 40. The shield 70 serves to shield electromagnetic waves coming from outside the housing 60 and electromagnetic waves radiated in the internal space.

[0029] FIG. 11 is a perspective view of the shield 70. The shield 70 includes a first bottom surface portion 71, a second bottom surface portion 72, and a connecting portion 73 that connects the first bottom surface portion 71 and the second bottom surface portion 72. That is, the shield 70 has a stepped bottom surface.

[0030] The first bottom surface portion 71 of the shield 70 is disposed so as to face the second surface 40b of the circuit board 40, and has a second shape having at least a fifth side 71a, a sixth side 71b, a seventh side 71c, and an eighth side 71d in a plan view of the shield 70. The second shape is, for example, a second rectangular shape. Further, the first bottom surface portion 71 includes a hole 71e disposed so as to include the central portion of the second shape. The hole 71e has a third shape in a plan view of the shield 70. The third shape is, for example, a circular shape.

[0031] The second bottom surface portion 72 of the shield 70 corresponds to the hole 71e disposed so as to include the central portion of the second shape of the first bottom surface portion 71, faces the second surface 40b of the circuit board 40, and is disposed farther from the first bottom surface portion 71 with respect to the second surface 40b of the circuit board 40. The second bottom surface portion 72 corresponds to the bottom surface of the housing 60. Further, the above-described connector 80 is disposed so as to pass through the hole 71e and penetrate the second bottom surface portion 72.

[0032] The connecting portion 73 of the shield 70 connects the entire circumference of the hole 71e disposed so as to include the central portion of the second shape of the first bottom surface portion 71 and the entire circumference of the second bottom surface portion 72.

[0033] Furthermore, the shield 70 includes a first side surface portion 74a disposed in a direction opposite to the second bottom surface portion 72 corresponding to the fifth side 71a of the first bottom surface portion 71, a second side surface portion 74b disposed in a direction opposite to the second bottom surface portion 72 corresponding to the sixth side 71b of the first bottom surface portion 71, a third side surface portion 74c disposed in a direction opposite to the second bottom surface portion 72 corresponding to the seventh side 71c of the first bottom surface portion 71, and a fourth side surface portion 74d disposed in a direction opposite to the second bottom surface portion 72 corresponding to the eighth side 71d of the first bottom surface portion 71.

[0034] At least a part of the first side surface portion 74a faces the first end surface 40c1 of the circuit board 40. At least a part of the second side surface portion 74b faces the second end surface 40c2 of the circuit board 40. At least a part of the third side surface portion 74c faces the third end surface 40c3 of the circuit board 40. At least a part of the fourth side surface portion 74da faces the fourth end surface 40c4 of the circuit board 40.

[0035] As shown in FIG. 8, the in-vehicle camera 100 further includes a resin member 90. The resin member 90 is made of a resin having a predetermined thermal conductivity, such as a silicone resin, and is disposed around the entire circumference of the hole 71e including the central portion of the second shape of the first bottom surface portion 71 between the circuit board 40 and the first bottom surface portion 71 of the shield 70. In the embodiment, the resin member 90 is a rectangular frame-shaped member surrounding the hole 71e and has a through hole 91 at the center in a plan view. Since the resin member 90 has a predetermined thermal conductivity, it dissipates heat generated from the circuit board 40 and the like, aiming at the smooth operation of the in-vehicle camera 100. Further, the resin member 90 contains a magnetic material, which will be described later.

[0036] In a state where the housing 60 houses the circuit board 40, the imaging element 50, the shield 70, and the resin member 90, the ring member 20 is welded to the flange portion 32 of the lens unit 30 on the radially inner side and to the first end portion 63 of the housing 60 on the radially outer side over the entire circumference. This welding is performed, for example, by laser welding.

[0037] General laser welding is used, for example, in welding a first resin having a predetermined light transmittance at the wavelength of laser light and a second resin or a third resin having a lower light transmittance than that of the first resin. When the first resin is irradiated with laser light while pressure is applied to both resins, the laser light passes through the first resin without being absorbed. The transmitted laser light is absorbed on the surface of the second resin or the third resin having a lower light transmittance than the first resin. The energy of the absorbed laser is converted into heat, and the surface of the second resin or the third resin is heated. Further, by heat conduction, the surface of the first resin in contact with the surface of the second resin or the third resin is also heated. Thereby, both resins are melted at the interface between the first resin and the second resin or the third resin. When the irradiation of the laser is stopped, the melted resin solidifies, and both resins are welded together.

[0038] In the present embodiment, the ring member 20 is formed of the first resin, at least the flange portion 32 of the lens unit 30 is formed of the second resin, and at least the first end portion 63 of the housing 60 is formed of the third resin. In laser welding, first, the ring member 20 is pressed against the first flange surface 32a of the flange portion 32 of the lens unit 30 and irradiated with laser light to weld the lower surface of the ring member 20 and the first flange surface 32a. Thereafter, the ring member 20 is pressed against the first end portion 63 of the housing 60 and irradiated with laser light to weld the lower surface of the ring member 20 and the first end portion 63.

[0039] Incidentally, in order to ensure the performance of suppressing the leakage of noise into the in-vehicle camera 100 and the influence of external noise, that is, the so-called EMC (Electromagnetic Compatibility) performance, the internal circuit board 40 is covered with a metal shield 70 to block electromagnetic waves. However, in actual products, a situation may occur where the space between the shield 70 and the circuit board 40 acts as a capacitor having a predetermined parasitic capacitance. Furthermore, even if the shield 70 is provided, due to the characteristics of the internal structure of the in-vehicle camera 100, a so-called gap, which is a portion that cannot completely cover the circuit board 40 that can be a source of electromagnetic waves, is inevitably formed. As a result, a capacitor having a parasitic capacitance may induce a state where internal noise radiates or external noise flows in through a path including such a gap, resulting in a situation where electromagnetic waves cannot be sufficiently shielded.

[0040] Furthermore, in the embodiment, a resin member 90 for heat dissipation is disposed between the circuit board 40 and the first bottom surface portion 71 of the shield 70. There is a possibility that the resin member 90 may cause noise resonance in the above-described state and further adversely affect the operation of the in-vehicle camera 100.

[0041] Therefore, the resin member 90 of the present embodiment contains a magnetic material in addition to the resin having heat conductivity. The resin member 90 is in contact with the second surface 40b of the circuit board 40, the first side surface portion 74a, the second side surface portion 74b, the third side surface portion 74c, the fourth side surface portion 74d, and the first bottom surface portion 71 of the shield 70. The resin member 90 can be formed, for example, by mixing a magnetic material in powder form with a resin as a base material.

[0042] Thereby, since the resin member 90 is in contact with the circuit board 40 and the shield 70 to close the gap that can be a path for electromagnetic waves, radiation or inflow of noise can be effectively prevented. In addition, since the resin member 90 itself contains a magnetic material, it has a function of blocking or absorbing noise. Therefore, the resin member 90 can exhibit not only a heat dissipation effect but also a noise shielding effect, ensuring high reliability of the in-vehicle camera 100.

[0043] The magnetic material of the resin member 90 may be, for example, ferrite. Thereby, a magnetic material that is low-cost and easily available can be used.

[0044] The number of pixels of the imaging device 50 may be 1 megapixel or more. For example, the imaging device 50 may be a CMOS (Complementary Meta-Oxide-Semiconductor) image sensor having a number of pixels such as 1.3M (megapixel), 2M pixels, 3M pixels, 5M pixels, 8M pixels, etc.

[0045] Thereby, a high-precision image can be captured, and an image that can also support high-speed communication standards such as the 5G communication standard can be provided. As the number of pixels of the imaging device 50 increases, the signal processing speed becomes faster and unnecessary radiation is likely to occur. However, as in this embodiment, by applying the shielding action by the shield 70 and the resin member 90, in high-speed communication standards, it is possible to meet the demand for reducing unnecessary radiation at a high level. Also, by adopting a CMOS image sensor, a highly reliable imaging device 50 can be obtained.

[0046] The resin member 90 is a gel-like member that is solid but has a predetermined fluidity. For this reason, when the circuit board 40 is placed on the resin member 90 during the assembly of the in-vehicle camera 100, the resin member 90 deforms so as to expand outward in the radial direction. Then, the resin member 90 enters the gaps between the first end face 40c1 of the circuit board 40 and the first side face portion 74a of the shield 70, between the second end face 40c2 of the circuit board 40 and the second side face portion 74b of the shield 70, between the third end face 40c3 of the circuit board 40 and the third side face portion 74c of the shield 70, and between the fourth end face 40c4 of the circuit board 40 and the fourth side face portion 74d of the shield 70. As a result, as shown in FIG. 10, the resin member 90 may further contact the first end face 40c1, the second end face 40c2, the third end face 40c3, and the fourth end face 40c4 of the circuit board 40. Thereby, the shielding performance by the resin member 90 can be enhanced.

[0047] As a result of the above-described deformation, at least a part of the interface of the resin member 90 may be between the first surface 40a and the second surface 40b of the circuit board 40 in the direction of the optical axis L. Thereby, the shielding performance by the resin member 90 can be further enhanced. However, at least a part of the interface may be formed beyond the first surface 40a of the circuit board 40 toward the lens unit 30 side in the direction of the optical axis L.

[0048] The above-described connector 80 passes through the hole 71e of the shield 70 and penetrates not only the second bottom portion 72 but also the through hole 91 of the resin member 90. And as a result of the above-described deformation, the resin member 90 deforms so as to expand also inward in the radial direction, and closes the through hole 91. As a result, as shown in FIG. 10, the resin member 90 may be disposed on the entire circumference of the connector 80 at at least a part of the longitudinal direction of the connector 80. Thereby, the shielding performance by the resin member 90 can be further enhanced. When the in-vehicle camera 100 is disposed in the vehicle V, the first terminal 81 and the second terminal 82 of the connector 80 are electrically connected to the cable of the vehicle V. Thereby, power supply from the vehicle V and signal exchange with the vehicle can be ensured.

[0049] The connector 80 is, for example, a coaxial connector, the first terminal 81 is a ground connection terminal, and the second terminal 82 is a signal terminal. Thereby, power supply from the vehicle V and high-frequency signal exchange with the vehicle V can be ensured.

[0050] As described above, the first shape of the circuit board 40 is a first rectangular shape, the second shape of the first bottom portion 71 of the shield 70 is a second rectangular shape, and the third shape of the hole 71e of the shield 70 is a circular shape. Thereby, the in-vehicle camera 100 can be easily manufactured using members of general shapes.

[0051] Returning to FIG. 11, the shield 70 will be further described. The shield 70 has at least a first bottom surface portion 71, a connecting portion 73, and a second bottom surface portion 72 formed by a continuous curved surface. Also, a first shield gap portion 76a exists between the first side surface portion 74a and the second side surface portion 74b of the shield 70, a second shield gap portion 76b exists between the second side surface portion 74b and the third side surface portion 74c, a third shield gap portion 76c exists between the third side surface portion 74c and the fourth side surface portion 74d, and a fourth shield gap portion 76d exists between the fourth side surface portion 74d and the first side surface portion 74a.

[0052] FIG. 12 is a top view of the in-vehicle camera 100 with the lens unit 30, the circuit board 40, and the imaging device 50 removed, and FIG. 13 is a perspective view of FIG. 12. The resin member 90 is also disposed in the first shield gap portion 76a, the second shield gap portion 76b, the third shield gap portion 76c, and the fourth shield gap portion 76d. In-vehicle camera.

[0053] By providing four gap portions between the four side surface portions of the shield 70, the bending of the four side surface portions with respect to the first bottom surface portion 71 becomes easy, and the shield 70 can be easily formed. Also, since the resin member 90 is disposed in the four gap portions that can be paths of electromagnetic waves, the shielding performance by the resin member 90 can be enhanced.
