DETAILED DESCRIPTION OF THE INVENTION

(8) A mounting structure of a camera according to an exemplary embodiment will be described more fully hereinafter with reference to the accompanying drawings.

(9) As shown in FIGS. 1 and 2, a vehicle 11 includes a metallic back door 12, which is provided to be freely opened and closed, constituting an exterior component of the vehicle 11 in a rear part thereof. A first recessed part 14, which a number plate 13 is mounted, is formed in a central lower part on an external surface of the back door 12. A second recessed part 15 is formed to extend in a width direction of the vehicle 11 in a position adjacent to an upper side with respect to the first recessed part 14 on the external surface of the back door 12.

(10) A base member 16 having a rectangular flat plate shape that constitutes the exterior component of the vehicle 11 is fixed on a bottom surface of the second recessed part 15. A camera 17 for capturing an image of a rear view of the vehicle 11, which is one of surrounding views of the vehicle 11, and a decorative member 18 are mounted on the base member 16. That is, the mounting structure of the camera 17 in the vehicle 11 according to the exemplary embodiment includes the base member 16, the camera 17, and the decorative member 18.

(11) The camera 17 is provided with a lens 17a on a tip end part thereof. All of the base member 16 and the decorative member 18 are constituted by a synthetic resin. The decorative member 18 is formed of a bottomed box shape having an approximately U-shape in a cross-sectional view. Further, the decorative member 18 is joined to the base member 16 in such a manner that an end edge part 18a of the decorative member closely contacts the base member 16 in a state of covering the camera 17.

(12) Accordingly, the camera 17 is disposed in a closed space surrounded by the base member 16 and the decorative member 18, that is, disposed in a region of an inside of the decorative member 18. Further, the end edge part 18a of the decorative member 18 may be welded to the base member 16, bonded thereto by an adhesive, or bonded thereto by a double-side adhesive tape.

(13) The decorative member 18 is constituted by a transparent synthetic resin such as an acrylic resin (PMMA) and a polycarbonate (PC). A half-plated layer 18b having transmittance ranging from about 30% to 50% is formed on the overall external surface of the decorative member 18. Therefore, the decorative member 18 is a lustrous product that looks like a mirror when viewed from the external surface. Further, the decorative member 18 covers the camera 17 in such a manner that the camera 17 disposed in the inside thereof is not disturbed to image an image of an outside of the decorative member 18. That is, the decorative member 18 is a half-mirror structure.

(14) In the back door 12, a first communication hole 12a forming a communication hole is formed to penetrate the back door 12. In the base member 16, a second communication hole 16a forming a communication hole is formed to penetrate the base member 16. The first communication hole 12a and the second communication hole 16a are communicated with each other. Accordingly, a region (inside a vehicle) of an inside of the back door 12 and a region of an inside of the decorative member 18 are communicated with each other through the first communication hole 12a and the second communication hole 16a.

(15) Next, an action of the mounting structure of the camera 17, formed as described above, will now be described.

(16) As shown in FIG. 2, with respect to the mounting structure of the camera 17 in the vehicle 11 according to the exemplary embodiment, the camera 17 does not protrude toward the outside of the decorative member 18, and is completely covered by the decorative member 18 having the half-mirror structure. Accordingly, the camera 17 is not seen from the outside of the decorative member 18, and the camera 17 disposed in the inside of the decorative member 18 performs capturing the image of the outside of the decorative member 18. Therefore, it is advantageously possible to prevent deterioration of design characteristics of an exterior of the vehicle 11 caused by the camera 17.

(17) Further, even in a case where the vehicle 11 is exposed to water such as rainwater, and the like, since the decorative member 18 closely contacts the base member 16, it is possible to prevent outside water from a gap between the base member 16 and the decorative member 18 from entering into the inside of the decorative member 18. Therefore, the camera 17 is prevented from being wet with the water. Accordingly, since the camera 17 is not required to be provided with a waterproof function, the camera 17 can be smaller than a camera having the waterproof function.

(18) Further, since the region (inside the vehicle) of the inside of the back door 12 and the region of the inside of the decorative member 18 are communicated with each other through the first communication hole 12a and the second communication hole 16a, air in the region of the inside of the back door 12 and air in the region of the inside of the decorative member 18 come and go through the first communication hole 12a and the second communication hole 16a. Therefore, since air permeability in the region of the inside of the decorative member 18, in which the camera 17 is disposed, is secured, the lens 17a of the camera 17 can be prevented from being cloudy.

(19) According to the exemplary embodiment fully described above, effects are performed as described hereinafter.

(20) (1) The decorative member 18 closely contacts the base member 16, and the camera 17 is disposed in the region of the inside of the decorative member 18. Accordingly, since the camera 17 does not protrude toward the outside of the decorative member 18, it is advantageously possible to prevent the design characteristics of the exterior of the vehicle 11 from deteriorating. Further, the decorative member 18 closely contacts the base member 16. Accordingly, since the outside water from the gap between the base member 16 and the decorative member 18 can be prevented from entering into the inside of the decorative member 18, the camera 17 can be prevented from being wet. Therefore, it is advantageously possible not only to prevent the design characteristics of the exterior of the vehicle 11 from deteriorating, but also to prevent the camera 17 covered by the decorative member 18 from being wet. Additionally, since the camera 17 can be prevented from being wet such that the camera 17 is not required to be provided with the waterproof function, the camera 17 can be miniaturized.

(21) (2) The camera 17 is disposed in the inside of the decorative member 18, and the decorative member 18 is formed to be the half-mirror structure. Accordingly, it is possible not only to image the image of the outside of the decorative member 18 by using the camera 17, but also to prevent the camera 17 from being seen from the outside.

(22) (3) The inside of the back door 12 and the inside of the decorative member 18 are communicated with each other through the first communication hole 12a and the second communication hole 16a. Accordingly, since the air permeability in the region of the inside of the decorative member 18 can be secured, the lens 17a of the camera 17 can be prevented from being cloudy.

(23) Further, the above-mentioned exemplary embodiments may be modified as described hereinafter.

(24) As shown in FIG. 3, the tip end part in which the lens 17a is disposed in the camera 17 is fitted into a recessed part 18c that is formed on the internal surface of the decorative member 18, and a plated layer 18d may be formed on a portion other than a portion corresponding to a viewing range of the camera 17 on the external surface of the decorative member 18, instead of adopting the half-plated layer 18b. In this case, the portion corresponding to the viewing rang of the camera 17 in the decorative member 18 is formed to be thin only in the recessed part 18c. Further, in this case, the portion corresponding to the viewing rang of the camera 17 in the decorative member 18 is not formed to have the plated layer 18d on the external surface, but formed to be transparent thereon. However, when it is possible to image the image of the outside of the decorative member 18 by using the camera 17, the portion may be formed to be translucent. Accordingly, the tip end part of the camera 17 can be supported by the decorative member 18. Additionally, the first communication hole 12a and the second communication hole 16a may be omitted.

(25) As shown in FIG. 4, the tip end part in which the lens 17a is disposed in the camera 17 is fitted into a through hole 18e formed in the decorative member 18 through a seal member 19 such as an O-ring, and the like, and the plated layer 18d may be formed on a portion other than the through hole 18e on the external surface of the decorative member 18, instead of adopting the half-plated layer 18b. In this case, an external surface of the lens 17a of the camera 17 is flush with the external surface of the decorative member 18. Accordingly a portion other than the lens 17a in the camera 17 can be prevented from being wet with water such as rainwater, and it is advantageously possible to clearly image the image of the outside of the decorative member 18 by using the camera 17. Further, a synthetic resin material, by which the decorative member 18 is constituted, may be opaque, and the first communication hole 12a and the second communication hole 16a may be omitted.

(26) As shown in FIG. 5, the tip end part of the camera 17 is bent in a downward direction and thus the lens 17a is directed in the downward direction, and a lower-side through hole 18f is formed in a position opposite to the lens 17a in the decorative member 18. Further, the plated layer 18d may be formed on a portion other than the lower-side through hole 18f on the external surface of the decorative member 18, instead of adopting the half-plated layer 18b. In this case, an internal surface of the lower-side through hole 18f is constituted by a mirror, such that the camera 17 images the image of the outside of the decorative member 18 (a downward direction of the vehicle 11) through the mirror. Additionally, the first communication hole 12a and the second communication hole 16a may be omitted.

(27) As shown in FIG. 6, the camera 17 may be integrally formed with the decorative member 18 by insert molding in such a manner that the external surface of the lens 17a of the camera 17 is flush with the external surface of the decorative member 18, and the plated layer 18d may be formed on a portion other than an exposed portion of the lens 17a on the external surface of the decorative member 18, instead of adopting the half-plated layer 18b. Further, the first communication hole 12a and the second communication hole 16a may be omitted.

(28) The first communication hole 12a and the second communication hole 16a may be omitted.

(29) The decorative member 18 is not necessarily required to be a half-mirror structure.

(30) The camera 17 may be supported not by the base member 16, but by the decorative member 18.

(31) An arrangement position of the camera 17 may be desirably modified to image images of a front view and a side view of the vehicle 11 with respect to the surroundings of the vehicle 11.

(32) The base member 16 may be omitted.
