Further, a hollow boss 122 for fixing the decorative cover 12 to the base plate 11 is protruded inward from a part of the decorative cover 12, and the screw N1 can be inserted therethrough.

  The camera 2, the room lamp RL, the map lamp ML, and the circuit structure 3 are supported by the base plate 11, but the camera 2 is supported by the base plate 11 via a bracket 13 that is separate from the base plate 11. Has been. That is, the camera 2 is fixedly supported by a bracket 13, and the bracket 13 is fixed to the base plate 11. The bracket 13 is made of a metal plate bent into a substantially L shape, and its front edge 131 is directed vertically downward, and the left-right direction of the front edge 131 is directed to the front-rear direction of the automobile. It is oriented in the vehicle width direction perpendicular to the axle. The front edge portion 131 has a circular lens insertion hole 132 through which the photographing lens portion 22 protruding from the front surface of the camera body 21 of the camera 2 can be inserted. In addition, a pair of small-diameter mounting holes 133 are opened on both sides of the front edge portion 131 sandwiching the lens insertion hole 132 on the left and right (the vehicle width direction, hereinafter the same).

  Then, the photographing lens portion 22 of the camera 2 is inserted into the lens insertion hole 132 from the rear surface side of the front edge portion 131, and the front surface of the camera body 21 of the camera 2 is brought into contact with the rear surface of the front edge portion 131. Let Then, screws N3 (only one screw is shown) are inserted through the pair of mounting holes 133 from the front side of the front edge portion 131, and mounting screw holes 23 provided on the left and right of the camera body 21 of the camera 2. The camera 2 is fixedly supported on the front edge portion 1231 by being screwed to the front edge portion 1231. With this mounting structure, the camera 2 has a camera optical axis direction (lens optical axis of the lens portion 22) perpendicular to the front edge portion 131, and an angular position around the camera optical axis is a predetermined angular position. Thus, the bracket 13 is automatically fixed and supported.

  Further, the lower surface of the rear edge portion 134 extending substantially in the horizontal direction of the bracket 13 is extended along a direction parallel to the camera optical axis of the camera 2, in other words, along a direction parallel to the axle direction. A guide rail 135 made up of at least one triangular section, here three ridges, which are arranged in a direction perpendicular to the direction, is integrally formed. Further, one screw fastening hole 136 is opened in a part of the rear edge portion 135 in the thickness direction. A rear edge portion 134 of the bracket 13 is overlaid on the upper surface of the front end portion 111 of the base plate 11, and extends on the upper surface of the front end portion 111 of the base plate 11 along a direction parallel to the axle direction. In addition, a plurality of guide rails 112 each having a triangular cross-section arranged in a direction perpendicular to the extending direction, here, five ridges, are integrally formed side by side in the left-right direction. In addition, one long hole 113 having a required length in the arrangement direction of the guide rails 112 is opened in the plate thickness direction at a position corresponding to the screw fastening hole 136 provided in the bracket 13.

  FIG. 5A is a partially cutaway side view of FIG. 3 for explaining these guide rails 135 and 112, and FIG. 5B is a sectional view taken along line BB. After the rear edge portion 134 of the bracket 13 is placed on the upper surface of the front end portion 111 of the base plate 11, the guide rails 135 and 112 provided on the bracket 13 are engaged with each other, and the fastening screw N 4 is elongated from the bottom of the base plate 11. The brat 13 can be fixed to the base plate 11 by inserting the screw 113 and screwing the screw 113 into the screw fastening hole 136 of the bracket 13. As a result, the camera 2 can be fixedly supported on the base plate 11 via the bracket 13 as described above, and further, the camera 2 is fixedly supported on the roof panel RFP of the automobile via the base plate 11, so that the mechanical It will be supported in a stable state. On the other hand, the fastening of the fastening screw N4 is loosened and moved in the elongated hole 113, and the relative meshing state of the guide rails 135 and 112 respectively provided on the bracket 13 and the base plate 11 is changed, whereby FIG. ), The bracket 13 is moved in the left-right direction perpendicular to the axle with respect to the base plate 11 with respect to the base plate 11 to fix the left-right direction, that is, the left-right direction of the camera optical axis of the camera 2 with respect to the base plate 11. The position of can be changed. Even when the left and right position of the camera 2 with respect to the base plate 11 is changed in this way, the guide rails 135 and 112 of the bracket 13 and the base plate 11 are extended in the axle direction. It is possible to maintain a state that matches the axle direction. Further, by providing a margin for the dimension of the elongated hole 113 in the camera optical axis direction, it is possible to adjust the position of the bracket 13 relative to the base plate 11 in the camera optical axis direction by this margin.

  Further, in the first embodiment, the lens hood 14 is attached to the front surface of the front edge portion 131 of the bracket 13. The lens hood 14 is used to block light in an angle region outside the shooting angle of view of the camera 2, and is molded with a resin having a low reflectivity surface that is difficult to reflect black or has a color similar thereto. Is formed in a quadrangular pyramid shape. In this case, the inner surface of the lens hood 14 may be rough to reduce the light reflectance. The front end portion of the lens hood 114 has a tapered shape so as to be close to or close to the inner surface of the front window FW of the automobile. A circular hole 141 corresponding to the photographing lens portion 22 of the camera 2 is opened at the rear end portion. The rear end portion is integrally provided with a flange 142 projecting in both the left and right directions, and a pair of insertion holes 143 are opened in the flange 142.

  The lens hood 14 has a flange 142 abutted against the front surface of the front edge 131 when the camera 2 is fixedly supported on the front edge 131 of the bracket 13. The mounting screw N3 is inserted into the insertion hole 143, and the mounting hole 133 of the front edge 131 is further inserted, and then screwed into the mounting screw holes 23 provided on the left and right of the camera body 21 of the camera 2. Thus, the lens hood 14 can be supported on the bracket 13 at the same time that the camera 2 is fixedly supported on the bracket 13. By providing the lens hood 14, when the camera 2 captures the front area of the host vehicle, disturbance light emitted from the left and right sides of the host vehicle or from above is incident on the lens unit 22 of the camera 2. It is possible to prevent so-called fog light and to capture a high-contrast image. By increasing the contrast of the image, it is possible to increase the recognition accuracy of an object existing in the front area of the host vehicle. The lens hood 14 is attached with a notch 123 provided at the front end of the decorative cover 12 and extending from the inside of the decorative cover 12 to the front outer region through the notch 123.

  The camera 2 housed in the casing 1 in this way is electrically connected to the circuit structure 3 housed in the rear region of the casing 1 by required wiring. Then, the image picked up by the camera 2 is subjected to signal processing in the circuit structure 3, and the obtained image signal is sent to a vehicle ECU that is not shown in the figure, whereby various controls can be realized. The wiring is preferably supported in the casing 1 by a clamp member or the like provided on the base plate 11.

  In the first embodiment, when the room light unit RLU is mounted on the automobile, the camera 2 is fixedly supported on the front edge 131 of the bracket 13 using the screw N3 as described above. At this time, the lens hood 14 is fixed simultaneously. Then, the rear edge portion 134 of the bracket 13 is fixed to the base plate 11 using the fastening screw N4. Then, the base plate 11 is fixed to the roof panel RFP of the passenger car with screws N2. Thereby, the camera 2 and the lens hood 14 are fixed to the roof panel RFP. Then, the decorative cover 12 is covered from below the base plate 11, and the decorative cover 12 is attached to the base plate 11 by screwing the screw N <b> 1 inserted from below through the hollow boss 122 to the base plate 11. As a result, the camera 2, the room lamp RL, the map lamp ML, and further the circuit structure 3 are covered with the base cover 11 and the bracket 13 by the decorative cover 12, and are installed in the casing 1, so that the room light unit RLU Is assembled.

  When the camera 2 is assembled to the room light unit RLU of the first embodiment, only the operation of attaching the camera 2 and the lens hood 14 to the bracket 13 and the operation of attaching the bracket 13 to the base plate 11 are required. Work can be greatly simplified. In addition, since the camera 2 is not mounted on the vehicle independently, a housing and special parts for mounting the camera are not necessary. Furthermore, in the first embodiment, the bracket 13 and the base plate 11 are made of metal plates, so that the mechanical strength is higher than in the case where the brackets 13 and the base plate 11 are made of resin. Also, the position fluctuation of the camera optical axis of the camera 2 can be suppressed. Further, since the heat generated when the room lamp RL and the map lamp ML are turned on is radiated from the bracket 13 and the base plate 11 or transferred to the roof panel RFP, the heat deformation of the decorative cover 12 due to the heat is prevented. At the same time, the influence of heat on the camera 2 can be prevented, which is advantageous in preventing the position fluctuation of the camera optical axis of the camera 2. Furthermore, by installing the camera 2 in the casing 1 as the interior light unit RLU in this way, the camera 2 is not exposed to the interior and exterior of the automobile, the appearance of the automobile is improved, and the camera 2 can be protected from external force or the like.

  When the interior light unit RLU is mounted on the automobile, the angular position around the camera optical axis of the camera 2 is automatically set to a predetermined position by the mounting hole 133 provided in the front edge portion 131 of the bracket 13. As described above. Even when the camera 2 is fixed to the base plate 11 in this way, the engagement state of the guide rails 135 and 112 of the bracket 13 and the base plate 11 is changed by tightening or loosening the fastening screw N4. It is possible to adjust the optical axis position in the left-right direction. With this operation, the optical axis of the camera 2 can be adjusted so that the camera optical axis coincides with the vehicle axle, and the imaging center of the camera 2 is set at a predetermined position in front of the host vehicle. In addition, since the lens hood 14 is also moved integrally in the vehicle width direction in accordance with the position adjustment of the camera 2 in the vehicle width direction, the notch 123 provided at the front end portion of the decorative cover 12 moves the movement. It is preferable that the dimensions be acceptable.

  The left-right position adjustment of the camera 2 is performed when the room mirror (rear mirror) RM is disposed on the front window in the vicinity of the room light unit RLU as shown in FIG. This is effective in avoiding interference with the mirror RM. That is, if the room mirror RM is within the imaging angle of view of the camera, vignetting will occur in the captured image. In such a case, as described above, the engagement of the guide rails 135 and 112 is changed to adjust the horizontal position of the bracket 13 with respect to the base plate 11 to change the relative position of the camera optical axis. The relative position of the camera 2 with respect to the room mirror RM can be changed to prevent interference with the room mirror RM, thereby reducing or preventing image vignetting. In addition, when adjusting the position of the camera 2 in the vehicle width direction, it is preferable to adjust the camera optical axis so as to be closer to the center of the road. In other words, in the case of left-passing Japan, adjustment is made so that the camera optical axis is positioned on the right side of the host vehicle with respect to the room mirror RM. Thereby, it becomes possible to image a wide area including the own lane and the opposite lane in the front area of the own vehicle.

With this configuration, the fastening operation of the screw N3 in Embodiment 1 when the camera 2 is fixed to the bracket 13 becomes unnecessary, and the fixing operation of the camera 2 can be simplified.

  In the second embodiment, as shown in FIG. 7, the lens hood 14 is formed integrally with the decorative cover 12. That is, the front end portion of the decorative cover 12 is extended in a pyramid shape to a position in front of the front end position of the lens portion 22 of the camera 2 and close to the inner surface of the front window FW, and this pyramid portion is configured as the lens hood 14. . By providing the lens hood 14, it is possible to prevent ambient light from entering the camera 2 as in the first embodiment, but an independent lens hood as in the first embodiment is not necessary and the number of components is reduced. It becomes possible to do. In this case, it is preferable to form the inner surface of the lens hood 14 in black or a low-reflectance and rough surface according to this regardless of the color of the decorative cover 12. The lens hood 14 may be configured such that the front end surface of the decorative cover 12 is extended to a position close to the front window FW, and an inner surface with a part thereof recessed backward is configured as a lens hood.

  Furthermore, in the second embodiment, the room mirror RM is integrated with the room light unit RLU. Here, an opening window 124 is formed on a part of the lower surface of the decorative cover 12, the stem 4 of the room mirror RM is inserted into the opening window 124, and the flange portion 41 at the upper end of the stem 4 is fixed to the base plate 11 with screws. doing. Here, the bracket 13 is fixed using a screw N4 for fixing the bracket 13 to the base plate 11. In this way, if the room mirror RM is integrally assembled when assembling the room light unit RLU, the room mirror RM can be attached to the automobile at the same time as the room light unit RLU is installed in the automobile.

  Thus, when the room mirror RM is integrally formed with the room light unit RLU, the room mirror RM can be disposed behind the camera 2, so that the camera 2 does not interfere with the room mirror RM in the vehicle width direction. There is no need to adjust the position. Therefore, in the second embodiment, the guide rail 135 made of one ridge is formed on the bracket 13, and the guide rail 112 made of two ridges for positioning the guide rail 135 is formed on the base plate 11. The positioning of the bracket 13 with respect to the base plate 11 in the vehicle width direction is performed by the engagement of the guide rails 135 and 112. Thereby, the camera 2 can be positioned at a predetermined position in the vehicle width direction with respect to the base plate 11, that is, with respect to the automobile. Thus, in Embodiment 2, it is not necessary to move the lens hood 14 together with the camera 2 in the vehicle width direction. Therefore, the lens hood 14 may be formed integrally with the base plate 11.

  In the second embodiment, in place of the spring member 114 when the camera 2 is elastically supported by the bracket 13, illustration is omitted, but a part of the decorative cover 12 fixed to the base plate 1 is attached to the camera body 21 of the camera 2.
