  The illuminating device 200 according to the present embodiment is basically configured as described above. For example, the illuminating device 200 is configured as a light-emitting device (illuminating device) described in JP 2012-086620 A. It doesn't matter.

  Next, the mounting structure 10 of the lighting device 200 will be described. The mounting structure 10 is integrally formed with the door armrest 22 using a resin material such as plastic. However, the mounting structure 10 may not be an integrally molded product made of resin.

  As shown in FIGS. 3 to 7, the mounting structure 10 includes a pedestal 40 that is formed to protrude in a substantially U shape on the curved surface 36 of the door armrest 22, and a mounting portion 42 for fixing the lighting device 200 to the pedestal 40. And. The pedestal 40 includes a flat base portion 44 extending in a substantially vertical direction, a lower side wall portion 46 provided at the lower end (end portion in the Z1 direction) of the base portion 44, and the upper end (in the Z2 direction) of the base portion 44. And an upper side wall portion 48 provided at the end portion. The upper side wall 48 is located vertically below the end of the light guide 34.

  The attachment portion 42 includes an attachment portion main body 50 provided on the base portion 44, a movement restriction portion 52 provided on the back surface of the base trim 14 and in contact with the illumination portion 208 of the lighting device 200, and an upper wall portion 48 and movement restriction. And a connecting wall portion 54 that connects the portion 52. The attachment portion main body 50 includes a wide side wall portion 56 erected from one side portion of the base portion 44 (side far from the curved surface 36) and a side portion of the base portion 44 (side closer to the curved surface 36). It has a narrow support wall portion 60 that is erected and provided with an engaging claw (claw portion) 58 at the tip.

  The side wall portion 56 is a substantially rectangular plate-like member, and extends from slightly above the lower side wall portion 46 to the upper side wall portion 48. A die punching hole 62 having a shape corresponding to the support wall 60 is formed in a portion of the side wall 56 facing the support wall 60. The side wall portion 56 stands substantially perpendicular to the base portion 44. As can be understood from FIG. 6, the surface of the side wall portion 56 on the support wall portion 60 side is in surface contact with one side surface of the connector portion 206 constituting the lighting device 200. A draft of a predetermined angle θ toward the tip of the side wall 56 is set on a contact surface of the side wall 56 with the connector 206 (a surface of the side wall 56 on the support wall 60 side).

  The support wall portion 60 is erected on the base portion 44 so as to be inclined toward the side wall portion 56 by an angle substantially equal to the draft angle of the side wall portion 56 (predetermined angle θ) with respect to a normal line P of the base portion 44. Yes. The support wall portion 60 is formed with a convex portion 64 that protrudes toward the side wall portion 56.

  The convex portion 64 extends along the extending direction of the support wall portion 60 and has an outer surface having a circular cross section. Thereby, the convex portion 64 is in line contact with the other side surface of the connector portion 206. The convex portion 64 is formed such that the length dimension of the convex portion 64 is shorter than the length dimension of the support wall portion 60 in a state where the convex portion 64 is located at the approximate center in the longitudinal direction of the support wall portion 60. Further, the convex portion 64 is formed such that the width dimension of the convex portion 64 is shorter than the width dimension of the support wall portion 60 in a state where the convex portion 64 is positioned at the substantially center of the support wall portion 60 in the width direction. Thereby, since the support wall part 60 can be bent appropriately, the attachment nail | claw 58 with respect to the connector part 206 can be attached or detached suitably.

  On the surface of the support wall 60 opposite to the surface on which the convex portion 64 is formed, a rib 66 extending from the base end to the approximate longitudinal center is provided at the approximate center in the width direction. The rib 66 is integrally provided on the curved surface 36 of the door armrest 22. By providing such a rib 66, the rigidity of the support wall part 60 can be improved.

  The engaging claw 58 is integrally formed at the tip of the support wall portion 60. The engaging claw 58 protrudes toward the side wall part 56 from the support wall part 60 and contacts the back surface of the connector part 206 constituting the lighting device 200 (see FIG. 6). The engaging claw 58 is formed with a tapered surface 68 inclined toward the base portion 44 toward the side wall portion 56.

  The attachment portion main body 50 includes first to fourth projecting portions 70, 72, 74, and 76 that are provided on the base portion 44 and extend substantially in the horizontal direction (see FIG. 5). The first projecting portion 70 extends from the lower end of the side wall portion 56 to the other end of the base portion 44. The second projecting portion 72 extends from the approximate center in the width direction of the base portion 44 to the other end of the base portion 44 slightly above the first projecting portion 70 (Z2 direction). The third protruding portion 74 extends from the side wall portion 56 to substantially the center in the width direction of the base portion 44 above the second protruding portion 72. The fourth projecting portion 76 extends from the approximate center in the width direction of the base portion 44 to the other end of the base portion 44 above the third projecting portion 74.

  The protrusion length of each of the first to fourth protrusions 70, 72, 74, 76 gradually increases from one end to the other end. That is, the front end surfaces of the first to fourth projecting portions 70, 72, 74, 76 are inclined toward the base portion 44 side by a predetermined angle θ with respect to the plane of the base portion 44 toward the side wall portion 56 side. Yes. Thereby, each front end surface of the 1st-3rd protrusion part 70,72,74 contacts the front surface (surface toward the base part 44) of the connector part 206 which comprises the illuminating device 200, and the 4th protrusion part 76 is contacted. Will contact the front surface of the illumination unit 208 constituting the illumination device 200.

  A plate-like wall portion 78 that contacts the other side surface of the connector portion 206 is erected at the other end portion of the first projecting portion 70, and the other end of the illumination portion 208 is disposed at the other end portion of the fourth projecting portion 76. The plate-shaped wall part 80 which contacts the side surface of this stands upright. These wall portions 78 and 80 are formed integrally with the curved surface 36.

  The movement restricting portion 52 protrudes in a substantially H shape along the extending direction of the side wall portion 56 from a portion of the back surface (back surface) of the base trim 14 located above the end portion of the light guide 34 (Z2 direction). Is formed. The movement restricting portion 52 includes a pair of restricting plates 82 and 84 that are provided on the back surface of the base trim 14 and face each other, and an intermediate plate 86 that connects the restricting plates 82 and 84.

  Each of the regulating plates 82 and 84 is gradually narrowed toward the tip. An upper restricting surface 82 a that contacts the upper surface of the illumination unit 208 and a front restricting surface 82 b that contacts the front surface of the illumination unit 208 are formed on the front end side of the regulation plate 82 by cutting away the lower part thereof. Yes. Similarly, the lower part of the restriction plate 84 is cut off at the front end side of the restriction plate 84, so that the upper restriction surface 84 a that contacts the upper surface of the illumination unit 208 and the front restriction surface 84 b that contacts the front surface of the illumination unit 208. And are formed.

  The connecting wall portion 54 connects the upper side wall portion 48 and the one restricting plate 82 and covers the end portion of the light guide 34 from the side. Thereby, when attaching the illuminating device 200 to the attachment structure 10 etc., it can prevent that the light guide 34 hits | manages a manual operation or other components, and the said light guide 34 is damaged.

  Next, the attachment procedure of the illuminating device 200 with respect to the curved surface 36 of the door armrest 22 using the attachment structure 10 comprised as mentioned above is demonstrated.

  When attaching the lighting device 200 to the curved surface 36 of the door armrest 22, first, the front surface of the connector portion 206 is opposed to the base portion 44 and the connection portion 204 is aligned with the position of the end portion of the light guide 34. The lighting device 200 is advanced toward the base 40. Then, the front surface of the connector portion 206 contacts the tapered surface 68 of the engagement claw 58.

  Subsequently, when the lighting device 200 is pressed toward the base portion 44, the support wall portion 60 is elastically deformed so that the engaging claw 58 is displaced in a direction away from the side wall portion 56, and the side wall portion 56 and the engaging claw 58 are thus deformed. The connector part 206 enters between the two. When the illuminating device 200 is further pushed toward the base portion 44, the engaging claw 58 that has passed over the connector portion 206 returns to the original position and comes into contact with the back surface of the connector portion 206, and enters the inner hole of the connecting portion 204. The end of the light guide 34 is attached.

  At this time, the front surface of the connector portion 206 is in contact with the tip surfaces of the first to third projecting portions 70, 72, and 74. That is, the connector portion 206 has its front surface in contact with the tip surfaces of the first to third projecting portions 70, 72, and 74, and its rear surface contacts the engaging claw 58. It will be fixed.

  Also, one side surface of the connector portion 206 is in surface contact with the side wall portion 56, and the other side surface of the connector portion 206 is in line contact with the convex portion 64 and is in contact with the wall portion 78. Thereby, rattling of the connector part 206 with respect to the base part 44 is suppressed. Further, the front surface of the illumination unit 208 comes into contact with the distal end surface of the fourth protrusion 76 and the other side surface of the illumination unit 208 comes into contact with the wall 80. Thereby, the backlash of the illumination part 208 with respect to the base part 44 is suppressed.

  Furthermore, one flange portion 210 of the connector portion 206 contacts the wall surface of the side wall portion 56 and the other flange portion 212 of the connector portion 206 contacts the engaging claw 58. Therefore, the movement of the lighting device 200 in the vertically downward direction (Z1 direction) with respect to the base portion 44 is restricted. That is, the side wall part 56 and the engaging claw 58 function as a movement restricting unit that restricts the downward movement of the lighting device 200. However, the flange portion 210 may be non-contact with the side wall portion 56 and the flange portion 212 may be non-contact with the engaging claw 58 in a state where the lighting device 200 is mounted on the mounting structure 10. Good. Even in this case, it is possible to restrict the downward movement of the lighting device 200.

  In addition, since the upper surface of the illumination unit 208 comes into contact with the upper restriction surfaces 82a and 84a, the movement along the vertical upper direction (Z2 direction) of the illumination device 200 fixed to the base unit 44 is restricted. Therefore, it is possible to prevent the illuminating device 200 from moving vertically upward with respect to the base portion 44 and applying an excessive force to the light guide 34. However, the upper restriction surfaces 82a and 84a may be non-contact with the upper surface of the illumination unit 208 in a state where the illumination device 200 is mounted on the attachment structure 10. Even in this case, it is possible to suppress the amount of vertical upward movement of the lighting device 200 with respect to the base portion 44, and thus it is possible to prevent an excessive force from acting on the light guide 34.

  Furthermore, since the front surface of the illumination unit 208 is in contact with the front regulation surfaces 82b and 84b, the forward movement of the illumination unit 208 is regulated. Therefore, it is possible to prevent the illuminating unit 208 from moving forward with respect to the base unit 44 and applying an excessive force to the light guide 34. However, the front regulating surfaces 82b and 84b may be non-contact with the front surface of the illumination unit 208 in a state where the illumination device 200 is mounted on the mounting structure 10. Even in this case, since the amount of forward movement of the lighting device 200 with respect to the base portion 44 can be reduced, it is possible to prevent an excessive force from acting on the light guide 34.

  Furthermore, the connecting portion 204 is located vertically above the upper wall portion 48 (Z2 direction), and the claw portion 216 provided on the illumination portion 208 is located vertically above the wall portion 80. As a result, even when the lighting device 200 moves along the vertically downward direction (Z1 direction) with respect to the base portion 44, the connection portion 204 contacts the upper wall portion 48 and the claw portion 216 contacts the wall portion 80. Therefore, the downward movement of the lighting device 200 is restricted. That is, the upper side wall part 48 and the wall part 80 function as movement restricting means for restricting the movement of the lighting device 200 in the vertically downward direction.

  As described above, according to the mounting structure 10 of the lighting device 200 according to the present embodiment, the flat base portion 44 of the pedestal 40 provided on the curved surface 36 of the door armrest 22 (door lining 12). The lighting device 200 can be fixed by the mounting portion 42. Therefore, the lighting device 200 can be stably attached to the curved surface 36 of the door armrest 22 without using a screw member. Therefore, the man-hour for attaching the lighting device 200 can be reduced.

  In addition, when one flange portion 210 of the connector portion 206 contacts the side wall portion 56 and the other flange portion 212 of the connector portion 206 contacts the engaging claw 58, the base portion 44 of the lighting device 200 is vertically lowered. Restricts movement. Further, the upper wall portion 48 is positioned vertically below the connecting portion 204 and the wall portion 80 is positioned vertically below the other claw portion 216 formed in the lighting portion 208, whereby the vertical direction with respect to the base portion 44 of the lighting device 200 is increased. Restricts downward movement. That is, in the present embodiment, the base portion 44 extends along the vertical direction, but the pedestal 40 and the mounting portion 42 restrict the downward movement of the lighting device 200 with respect to the base portion 44. The lighting device 200 can be fixed to the base portion 44.

  According to the present embodiment, since the movement of the lighting device 200 in the direction away from the base portion 44 is restricted by the engaging claw 58, the lighting device 200 can be stably fixed to the base portion 44.

  Further, one side surface of the connector portion 206 is in surface contact with the side wall portion 56 and the other side surface of the connector portion 206 is in line contact with the convex portion 64 provided on the support wall portion 60. Thereby, the lighting device 200 can be more stably fixed to the base portion 44. Furthermore, the rattling of the lighting device 200 with respect to the base portion 44 is suppressed without increasing the dimensional accuracy of the lighting device 200 and the mounting structure 10 as compared with the case where both side surfaces of the connector portion 206 are in surface contact with the mounting portion 42. Can do.

  According to the present embodiment, since the convex portion 64 whose cross section is formed in an arc shape extends along the extending direction of the support wall portion 60, the convex portion 64 is placed on the other side surface of the connector portion 206. Line contact can be made.

  Moreover, since the length dimension of the convex part 64 is formed shorter than the length dimension of the support wall part 60, compared with the case where the convex part 64 is formed over the full length of the support wall part 60, it is a support wall. The part 60 can be easily bent. Accordingly, the lighting device 200 can be easily attached to the mounting portion 42 by bending the support wall portion 60 and displacing the engaging claw 58 to the side opposite to the side where the side wall portion 56 is located.

  Furthermore, since the width dimension of the convex part 64 is formed shorter than the width dimension of the support wall part 60, the support wall part 60 is compared with the case where the convex part 64 is formed over the entire width of the support wall part 60. Can be easily bent. Thereby, the illuminating device 200 can be more easily attached to the attachment portion 42.

  According to this embodiment, a draft angle of a predetermined angle θ is set on the contact surface of the side wall portion 56 with the connector portion 206, and the support wall portion 60 is substantially the draft angle with respect to the normal P of the plane of the base portion 44. The base portion 44 is erected so as to be inclined toward the side wall portion 56 by the same angle θ. Thereby, the rattling of the illuminating device 200 with respect to the base part 44 can be suppressed.

  Further, of the first to fourth projecting portions 70, 72, 74, 76, the contact surface with the lighting device 200 is substantially the same as the draft angle of the side wall portion 56 with respect to the plane of the base portion 44 toward the side wall portion 56 side. The angle is inclined toward the base 44 side. Thereby, the rattling of the illuminating device 200 with respect to the base part 44 can be suppressed further.

  Further, a die punching hole 62 is formed in a portion of the side wall portion 56 that faces the support wall portion 60. In this case, as shown in FIGS. 8 and 9, the engagement claw 58 can be easily formed using the mold 150 and the slide mold 152 that passes through the mold release hole 62.

  According to the present embodiment, since the pedestal 40 has the upper side wall portion 48 provided integrally with the upper end of the base portion 44 and the curved surface 36 of the door armrest 22, the rigidity of the pedestal 40 can be increased. it can. Thereby, the illuminating device 200 can be attached to the curved surface 36 of the door armrest 22 more stably. Moreover, the downward movement of the lighting device 200 with respect to the base portion 44 can be restricted by the upper wall portion 48 having relatively high rigidity.

  Furthermore, since the base 40 has the lower side wall part 46 provided integrally with the lower end of the base part 44 and the curved surface 36 of the door armrest 22, the rigidity of the base 40 can be further improved.

  In the present embodiment, since the upward upward movement of the lighting device 200 with respect to the base portion 44 is restricted by the upper restriction surfaces 82a and 84a constituting the movement restriction portion 52, the lighting device 200 is more stably door armrest. It can be attached to 22 curved surfaces 36.

  The present invention is not limited to the above-described embodiment, and it is naturally possible to adopt various configurations without departing from the gist of the present invention. For example, the lighting device mounting structure according to the present invention can be applied to any mounting target other than a door lining.
