  One of the side plates 3, for example, the rear side plate 3, has one relatively small opening 6 at the top, and only the lens cover 7 faces the inside of the car 101 in the opening 6. It is fitted so that it protrudes slightly. On the back side of the side plate 3 in which the opening 6 is formed, a camera box 8 in which the camera body is housed, which will be described in detail later, is arranged.

  Next, with reference to FIG. 3 and FIG. 4, a mounting structure of the in-car camera 200 will be described. 3 is a cross-sectional view of the car showing the vicinity of the in-car camera provided in the car shown in FIG. FIG. 4 is a rear view of the car when the vicinity of the in-car camera shown in FIG. 3 is viewed from the back side of the car.

  On the back side of the side plate 3 in which the opening 6 is formed, the camera box 8 that houses the camera body 9 is arranged as described above. The camera box 8 can be attached in various configurations. Here, a bracket 11 is arranged on the back surface side of the side plate 3, and an upper end (upper end) of the bracket 11 is fixed to the ceiling 5 side of the car 101 with a bolt 10. Specifically, the ceiling 5 includes a ceiling panel 5A and a ceiling rear panel 5B, and is configured by combining a plurality of panel members.

  The ceiling rear panel 5 </ b> B is disposed below the ceiling panel 5 </ b> A and is disposed between the ceiling panel 5 </ b> A and the upper end portion of the side plate 3. The ceiling rear panel 5 </ b> B has a flange 5 </ b> B <b> 1 that protrudes like a bowl toward the outside of the car 101 rather than the side plate 3. A bracket 11 is attached to the flange portion 5B1 from the upper surface side, and the bracket 11 is fixed to the flange portion 5B1 in a suspended state. For this purpose, a bent portion 11B is provided at the upper end portion of the bracket 11, and the bent portion 11B is attached so as to be hooked on the flange portion 5B1.

  A camera box 8 is attached to the lower end (lower end) of the bracket 11 that is suspended from the ceiling 5 side. For this purpose, a bent portion 11C is provided at the lower end of the bracket 11, and the camera box 8 is fixed to the lower surface side of the bent portion 11C.

  Between the bent part 11B and the bent part 11C, a hanging part 11D extending from the bent part 11B toward the lower side in the vertical direction is provided. The bent portion 11C and the bent portion 11C are bent from both ends in the vertical direction (vertical direction) of the hanging portion 11D toward the car 101 (side plate 3). Thereby, the camera box 8 can be attached close to the side plate 3, and the protrusion dimension of the camera box 8 from the side plate 3 can be reduced.

  The bracket 11 is manufactured as a strength member having substantially the same width as the camera box 8 as shown in FIG. The camera box 8 is pressed against the back side of the side plate 3 by sharpening the bending angle θb (see FIG. 3) of the bent portion 11B (θb <90 °). In addition, cushioning materials 12A and 12B are disposed between the camera box 8 and the back surface of the side plate 3, and the camera box 8 is pressed against the back surface of the side plate 3 via the cushioning materials 12A and 12B. keeping.

  With such a configuration, the collision between the camera box 8 and the back surface of the side plate 3 is prevented from being repeated due to vibration or the like when the car 101 is moved up and down, and the generation of noise in the same portion is prevented. In addition, by manufacturing the bracket 11 with a strength member in this way, the camera box 8 can be manufactured with a thin plate to reduce the weight.

  That is, the camera box 8 and the bracket 11 are formed of plate-like members, and the rigidity of the plate-like member (thick plate) constituting the bracket 11 is higher than the rigidity of the plate-like member (thin plate) constituting the camera box 8. . The rigidity of the bracket 11 is higher than the rigidity of the camera box 8. With such a configuration, the camera box 8 can be pressed against the side plate 3 in a stable state in addition to the weight reduction of the camera box 8.

  Even when the in-car camera 200 is attached after the car 101 is assembled, a camera box 8 incorporating the camera body 9 is connected in advance to the lower end of the bracket 11 so that the operator can mount the bracket from the ceiling 5 side. The upper end of the bracket 11 can be fixed to the ceiling 5 side with the bolt 10 while the camera box 8 is temporarily placed while holding the hand 11.

  A cutout opening 11 </ b> A is formed in an intermediate portion (the hanging portion 11 </ b> D) of the bracket 11. As described above, since the camera box 8 is arranged on the back side of the side plate 3, if the bracket 11 or the camera box 8 is attached with a bolt or the like, workability may be deteriorated. However, by using the bracket 11 in which the opening 11A is formed, the operator can use the opening 11A as a handle. The operator can hold the handle with his hand to attach the ceiling portion 5 (the ridge 5B1). The bracket 11 can be placed on the upper side of the bracket) and temporarily arranged.

  Further, when attaching the camera box 8 to the back side of the side plate 3, the operator holds it by hand using the opening 11A of the bracket 11, or temporarily supports a temporary holding tool (not shown) using the opening 11A. You can also Further, when attaching the camera box 8 at the narrow portion on the back side of the side plate 3, a hand or a tool can be inserted from the opening 11A to support the nut side during the bolt 10 tightening operation.

  The lens cover 7 divided from the camera box 8 can be attached in various configurations, but can be attached from the inside of the car 101. That is, an annular plate nut (a plate-like member having a female screw or a plate-like screw member) 13 is fixed to the camera box 8 located on the back side of the side plate 3 or the back side of the side plate 3, while the lens cover A threaded portion (male threaded portion) is formed on the outer periphery of the insertion side of 7. Therefore, the operator can attach the lens cover 7 by screwing the screw portion of the lens cover 7 into the plate nut 13 while inserting the lens cover 7 into the opening 6 of the side plate 3 from the inside of the car 101. it can. According to such a configuration, it is not necessary for an operator to enter the narrow portion on the back surface side of the side plate 3 to perform the work, and the lens cover 7 can be attached and detached from the inside of the car 1.

  The lens cover 7 is in communication with the concave portion (concave surface) 7 </ b> A formed on the back side thereof and the inside of the camera box 8. The camera body 9 disposed in the camera box 8 is located in the space formed by the recess 7A, with a part of the lens side on the recess 7A side which is the back side (concave surface) of the lens cover 7 described above. The other parts excluding the part are arranged inside (inside) the camera box 8.

  Further, the lens cover 7 has a structure that does not protrude greatly inside the car 101. For example, the lens cover 7 has a curved surface protruding toward the inside of the car 101 that is slightly thinner than the hemisphere, and protrudes from the side plate 3 to the inside of the car 101 than the diameter W7 on the camera box 8 side. The dimension L7 is formed to be small (L7 <W7). The diameter W7 of the lens cover 7 is a diameter along the plate surface of the side plate 3 in the opening 6 and is the maximum outer diameter of the lens cover 7. The diameter W7 of the lens cover 7 is larger than the diameter (diameter) W6 of the opening 6, but is substantially equal to the diameter W6 of the opening 6. Accordingly, the protruding dimension L7 of the lens cover 7 is smaller than the diameter W6 of the opening 6. Such a lens cover 7 constitutes a convex part with a small projecting dimension to the inside of the car 101, and a part of the camera body 9 is arranged in the concave part on the back side.

  In this embodiment, a camera box 8 that accommodates most of the camera body 9 and holds the camera body 9 is disposed on the back side of the side plate 3 (outside of the car 101), and the camera box 8 and the camera body 9 are large. The portion is arranged outside the car 101. For this reason, the occupied volume inside the car 101 of the camera body 9 can be reduced as much as possible. Thereby, the possibility that the baggage brought inside the car 101 and the camera box 8 and the camera body come into contact with each other can be reduced. In this embodiment, since the projection amount of the lens cover 7 to the inside of the car 101 is reduced, the possibility of contact between the lens cover 7 and the luggage brought into the car 101 can be further reduced. it can.

  Since it is necessary to adjust the viewing angle of the camera body 9, a support arm 14 is provided in the camera box 8, and the camera body 9 is supported by using a rotation shaft 15 that enables the support arm 14 to rotate. Yes. The rotating shaft 15 is not positioned on the lens cover 7 side of the plate nut 13 but is supported at a position retracted to the camera box 8 side of the plate nut 13 (position retracted from the inside of the car 101 to the outside). Has been.

  Accordingly, the viewing angle can be adjusted by rotating and removing the lens cover 7 from the inside of the car 101 and swinging the camera body 9 around the rotation shaft 15. When the camera body 9 is rotated to adjust the viewing angle, the portion located near the back surface of the lens cover 7 moves in a non-contact state with the inner surface of the concave portion of the lens cover 7. In this way, the configuration of the surveillance camera can adjust the viewing angle from the inside of the car 101 without projecting greatly inside the car 101.

  The camera body 9 can easily adjust the viewing angle because a part on the lens side is located in a space formed by the concave portion 7 </ b> A of the lens cover 7.

  In the present embodiment, the projecting dimension of the lens cover 7 toward the inside of the car 101 is such that the camera body 9 and the back surface of the lens cover 7 do not come into contact with each other even when the camera body 9 is rotated to adjust the viewing angle. Is set to have. Also in this case, since most of the camera body 9 is present outside the car 101 than the side plate 3, the distance between the camera body 9 and the back surface of the lens cover 7 can be reduced.

  On the other hand, it is conceivable to arrange the rotating shaft 15 closer to the lens cover 7 than the plate nut 13. However, in the case of such a configuration, when the camera body 9 is rotated around the rotation shaft 15 and the viewing angle is adjusted, the lens cover 7 protrudes more inside the car 101 than in the present embodiment. .
