Yes.

Japanese Patent Laid-Open No. 2002-104067

  In the lighting device described above, the claw provided on the lamp base side is only locked in the locking hole provided on the lens cover side. In the case of collision, the lens cover is easily detached from the lamp base due to the impact. In particular, it is not preferable that an edged member such as a lens cover is scattered in the vehicle interior.

  The present invention has been completed based on the above-described circumstances, and an object thereof is to effectively suppress scattering of an edged member such as a lens cover into a vehicle interior.

  The vehicle lighting device of the present invention includes a design surface panel attached to the design surface side portion of the console body, and a cover lens attached to the design surface panel and transmitting light from the light source set inside, An insertion piece having an engaging portion is provided on the periphery of the cover lens, and the design surface panel is inserted into the insertion hole into which the insertion piece is inserted and the insertion piece inserted into the insertion hole. It is characterized in that it is configured to include an engaged portion that engages with the engaging portion to hold the peripheral edge of the cover lens so as to restrict the movement of the piece in the insertion direction.

  According to such a configuration, the engaging portion can be engaged with the engaged portion by inserting the insertion piece into the insertion hole and attaching the cover lens to the design surface panel. That is, the movement of the insertion piece in the insertion direction is restricted by the engagement between the engaging portion and the engaged portion, and thus the cover lens can be prevented from coming off in the insertion direction of the insertion piece. Furthermore, since the insertion piece is surrounded by the inner peripheral wall of the insertion hole, it is possible to prevent the cover lens from coming off in a direction different from the insertion direction of the insertion piece. For this reason, for example, when an occupant collides with the console box at the time of a side collision, it is possible to effectively prevent a member having an edge such as a lens cover from coming off the design surface panel and scattering into the vehicle interior. .

The following configuration is preferable as an embodiment of the present invention.
A restriction protrusion may be further provided on the periphery of the cover lens, and a restriction recess that engages with the restriction protrusion and holds the periphery of the cover lens may be provided on the console body.

  According to such a structure, a cover lens can be attached to a console main body by engaging a control protrusion with a control recessed part. That is, the cover lens can be attached to both the design surface panel and the console body. Therefore, the scattering of the lens cover can be effectively suppressed as compared with the case where the engaging portion and the engaged portion are engaged only.

  The restricting protrusion may include a contact portion that contacts the restricting recess in the insertion direction of the insertion piece.

  According to such a configuration, the restricting protrusion and the restricting recess can be engaged in the insertion direction of the insertion piece by the contact by the contact portion.

  The restriction protrusion may further include a protrusion that locks the restriction recess in a direction intersecting the insertion direction of the insertion piece.

  According to such a configuration, the locking by the protrusion is added, so that the restricting protrusion and the restricting recess are related to both the insertion direction of the insertion piece and the direction in which the insertion direction of the insertion piece intersects. Can be combined. Therefore, the restricting protrusion and the restricting recess can be engaged more firmly than in the case where they are engaged in only one direction.

An engaged part is good also as a structure which consists of a latching protrusion which fits and latches with respect to an engaging part from the direction which cross | intersects the insertion direction of an insertion piece.
According to such a structure, the movement of the insertion piece in the insertion direction can be restricted by the locking projection being locked to the engaging portion.

  ADVANTAGE OF THE INVENTION According to this invention, it can suppress effectively that the members with standing edges, such as a lens cover, are scattered in a vehicle interior.

<Embodiment 1>
Embodiment 1 of the present invention will be described with reference to the drawings of FIGS. As shown in FIG. 1, the console box 10 in the present embodiment has a long shape in the vehicle front-rear direction, and is configured with a console body 20 made of a synthetic resin such as polypropylene as a main part. The console box 10 is disposed between the left and right front seats in the vehicle. The front side of the console main body 20 has a form protruding upward from the rear side of the vehicle. A storage portion 21 having a box shape that opens upward is formed in the upper portion of the console main body 20 at the rear of the vehicle, and the storage portion 21 is used as an accessory case.

  An illuminating device 30 is provided on the upper portion of the console body 20 on the vehicle front side. As shown in FIG. 4, the illumination device 30 is provided separately from the console main body 20 and is retrofitted to the console main body 20. The illumination device 30 includes a pair of line illuminations 31 that form a long line in the vehicle front-rear direction, and LEDs (not shown) disposed on one end side of both line illuminations 31. One LED is arranged for both line illuminations 31, and the light bifurcated from one LED is guided to one end side of both line illuminations 31.

  Both line illuminations 31 are fitted and mounted in mounting recesses 33 that are recessed in the left and right side edge portions on the design surface side of the design surface panel 32 shown in FIG. The design surface panel 32 has a curved shape with the front end hanging slightly downward. Accordingly, both line illuminations 31 have the same curved shape as the design surface panel 32. A panel opening is formed through the central portion of the design surface panel 32, and an operation panel (not shown) is disposed inside the panel opening.

  As shown in FIG. 3, the light emitting surface of the line illumination 31 is constituted by a cover lens 35 made of transparent polycarbonate. The cover lens 35 has a long shape in the vehicle front-rear direction. A plurality of upper insertion pieces 37 are provided on the upper edge 36 of the cover lens 35. Each upper insertion piece 37 is provided with a locking hole 41 having a substantially gate shape. On the other hand, a plurality of upper insertion holes 39 into which a plurality of upper insertion pieces 37 are inserted are opened in a wall 38 of the design surface panel 32 facing the cover lens 35. The plurality of upper insertion holes 39 are arranged at the upper end portion of the facing wall 38. The cover lens 35 is attached to the mounting recess 33 by the plurality of upper insertion pieces 37 being inserted into the plurality of upper insertion holes 39 from the vehicle width direction.

  As shown in FIG. 6, a plurality of locking protrusions 40 are provided on the lower surface of the design surface panel 32 so as to protrude downward. Specifically, the two locking projections 40 arranged side by side in the left-right direction form one set, and a plurality of sets are arranged in the longitudinal direction. When the cover lens 35 is attached to the design surface panel 32 from the vehicle width direction, each upper insertion piece 37 is inserted into each upper insertion hole 39 as shown in FIG. Then, each locking projection 40 fits into each locking hole 41 and locks in the vehicle width direction, whereby the upper edge 36 of the cover lens 35 is held at the proper mounting position.

  Further, as shown in FIG. 6, a plurality of lower insertion pieces 48 are provided on the lower edge 44 of the cover lens 35. Specifically, two lower insertion pieces 48 arranged side by side in the vehicle width direction form one set, and a plurality of sets are arranged in the longitudinal direction. As shown in FIG. 8, a locking projection 49 that protrudes downward is provided at the tip of each lower insertion piece 48. On the other hand, a plurality of lower insertion holes 50 into which a plurality of lower insertion pieces 48 are inserted are opened at the lower end portion of the facing wall 38. When the cover lens 35 is attached to the design surface panel 32 from the vehicle width direction, each lower insertion piece 48 is inserted into each lower insertion hole 50 as shown in FIG. When the mounting position is reached, the plurality of locking protrusions 49 are locked in the vehicle width direction with respect to the hole edges of the plurality of lower insertion holes 50, so that the lower edge 44 of the cover lens 35 is in the normal mounting position. Retained.

  That is, since the upper and lower insertion pieces 37 and 48 are inserted into the upper and lower insertion holes 39 and 50, the cover lens 35 has a direction (vertical direction and vehicle direction) that intersects this insertion direction (vehicle width direction). Movement in the front-rear direction and the like is restricted. Further, the cover lens 35 has a locking projection 40 locked in the vehicle width direction with respect to the hole edge of the locking hole 41, and a locking projection 49 on the hole edge of the lower insertion hole 50. On the other hand, since it is locked in the vehicle width direction, movement in the vehicle width direction is restricted. For this reason, when an occupant collides with the console body 20 from the vehicle width direction during a side collision of the vehicle, it is possible to effectively suppress the cover lens 35 from being detached from the design surface panel 32 due to the impact, and the cover lens 35 The whole can be held in a regular mounting position.

  As shown in FIG. 7, the opposing wall 38 extends from the lower end portion toward the cover lens 35, and a holding projection 42 is formed on the extended end portion so as to protrude downward. As shown in FIG. 5, a plurality of holding protrusions 42 are provided in the vehicle front-rear direction. On the other hand, a plurality of holding holes 22 are provided in the upper portion of the console body 20 at positions corresponding to the plurality of holding projections 42. As shown in FIG. 7, the holding projection 42 is configured to be locked in the vertical direction with respect to the hole edge portion of the holding hole 22. As a result, the design surface panel 32 is held at the proper mounting position with respect to the upper portion of the console body 20.

  A guide piece 46 is provided in the vicinity of the holding projection 42 as shown in FIG. A plurality of guide pieces 46 are provided in the vehicle front-rear direction corresponding to the plurality of holding projections 42. The outer peripheral edge portion of the guide piece 46 is formed in a tapered shape, and the tapered portion is in sliding contact with the hole edge of the holding hole 22. As a result, the design surface panel 32 is guided to the proper mounting position, and the holding projection 42 is guided into the holding hole 22.

  As shown in FIG. 3, a rod-shaped light guide 34 that extends in the vehicle front-rear direction along the opposing wall 38 is disposed inside the line illumination 31. The light guide 34 is made of acrylic, and is one of the light guide members that can guide light introduced from one end side to the other end side. The surface of the light guide 34 is subjected to a fluorine treatment (transmission light diffusion treatment) that allows light introduced into the light guide 34 to be diffused while being transmitted outward. For this reason, the light introduced into the light guide 34 from one end side of the light guide 34 is emitted to the outside on the way to the other end side, and the entire light emitting surface of the cover lens 35 emits light. That is, the light guide 34 corresponds to a “light source” in the present invention.

  As shown in FIG. 2, a pair of holes 47 are formed at both ends of the mounting recess 33 in the vehicle front-rear direction. As shown in FIGS. 3 and 6, both end portions of the light guide 34 are inserted into the holes 47. The light guide 34 is temporarily fixed to the design surface panel 32 by inserting both end portions of the light guide 34 into the lower surface side (non-design surface side) of the design surface panel 32 from both holes 47 of the mounting recess 33. The Thereby, when the cover lens 35 is mounted on the design surface panel 32, it is not necessary to hold the light guide 34 by hand so that the light guide 34 does not come off the mounting recess 33.

  As shown in FIG. 8, similarly to the light guide 34, a reflection member 43 having a long plate shape in the vehicle front-rear direction is laid in advance on the lower side of the light guide 34. The reflecting member 43 has an arcuate surface that is in close contact with the lower surface of the outer periphery of the light guide 34. For this reason, the light guide 34 can be satisfactorily attached and fixed in the vertical direction and the vehicle width direction.

  The reflecting member 43 is made of white polypropylene. That is, the reflecting member 43 has a function of reflecting light emitted from the light guide 34 to the outside. For this reason, since the light emitted to the reflecting member 43 side is reflected by the reflecting member 43 and collected on the cover lens 35 side, the illuminance on the light emitting surface of the cover lens 35 can be further increased. Further, by providing the reflecting member 43, the difference in brightness between the both end portions and the central portion of the light guide 34 can be reduced.

  Now, when the cover lens 35 is mounted on the light guide 34 temporarily fixed to the mounting recess 33 from the vehicle width direction, the light guide 34 is integrated with the reflecting member 43 as shown in FIG. It is held in a state of being sandwiched between the facing wall 38 of the face panel 32 and the cover lens 35. Specifically, the light guide 34 is substantially in contact with the inner surface of the cover lens 35 and the outer surface of the facing wall 38, and is in contact with the cover lens 35 via the reflecting member 43. That is, the cover lens 35 is configured to cover the light guide 34 and has a substantially gate-shaped cross-sectional shape that opens to the opposing wall 38 side. As a result, the light guide 34 is held in the proper mounting position by being pressed from three directions between the cover lens 35 and the facing wall 38.

  Further, as shown in FIG. 9, the lower edge 44 of the cover lens 35 is provided with a regulation protrusion 45 that protrudes downward. As shown in FIG. 5, a plurality of restricting protrusions 45 are provided in the vehicle front-rear direction corresponding to the plurality of holding protrusions 42. Each restricting protrusion 45 is arranged adjacent to each holding protrusion 42. For this reason, each regulating projection 45 is inserted into the same holding hole 22 as each corresponding holding projection 42. That is, the holding hole 22 is a common hole into which both of the adjacent regulating protrusion 45 and holding protrusion 42 are inserted.

  As shown in FIG. 9, the restricting protrusion 45 is locked in the vehicle width direction with respect to the inner wall constituting the holding hole 22, whereby the lower edge 44 of the cover lens 35 is separated from the holding hole 22. Opening is restricted. For example, when the light guide 34 has a slightly larger diameter, the light guide 34 contacts both the opposing wall 38 and the cover lens 35, and the lower edge 44 of the cover lens 35 is placed on the side. It can be considered to act in the direction of pushing out. Even in that case, since the restricting protrusion 45 is locked to the inner wall of the holding hole 22, the light guide 34 is held at the proper mounting position, and the opening of the lower edge 44 of the cover lens 35 is restricted. The

  Further, when the console body 20 receives an impact in the vehicle width direction from the occupant at the time of a side collision of the vehicle, the insertion pieces 37 and 48 are pulled out from the insertion holes 39 and 50 by the impact, and the cover lens 35. May be scattered in the passenger compartment. However, since the lower edge 44 of the cover lens 35 is held in the holding hole 22 by the restricting protrusion 45, the cover lens 35 can be prevented from scattering into the vehicle interior. Further, depending on the direction of impact received in the case of a side collision, the cover lens 35 may come out upward while rotating about the light guide 34. However, even in that case, since the restricting protrusion 45 is also locked in the rotation direction of the cover lens 35 with respect to the holding hole 22, it can be avoided that the cover lens 35 is detached while rotating.

  The present embodiment is configured as described above, and its operation will be described subsequently. First, a method for assembling the lighting device 30 will be briefly described. A reflective member 43 is mounted in the mounting recess 33 of the design surface panel 32 shown in FIG. 2, and the light guide 34 is mounted on the reflective member 43. Then, as shown in FIG. 3, both ends of the light guide 34 are inserted into the holes 47, and the light guide 34 is temporarily fixed together with the reflecting member 43 to the mounting recess 33. From this state, the cover lens 35 is attached to the mounting recess 33 from the vehicle width direction. At this time, the upper and lower insertion pieces 37 and 48 are inserted into the upper and lower insertion holes 39 and 50, so that the mounting operation of the entire cover lens 35 is guided, and the inner walls of the locking protrusion 40 and the locking hole 41. Are locked in the vehicle width direction, and the locking protrusion 49 and the hole edge portion of the lower insertion hole 50 are locked in the vehicle width direction. Thereby, the upper edge 36 and the lower edge 44 of the cover lens 35 are fixed with respect to the design surface panel 32, and the illuminating device 30 is completed as shown in FIG.

  Next, the lighting device 30 is attached to the upper portion of the console body 20 on the vehicle front side. First, the illuminating device 30 is guided to the regular mounting position by the outer peripheral edge of the guide piece 46 being in sliding contact with the hole edge of the holding hole 22. Accordingly, the holding projection 42 is guided to the holding hole 22, and the regulation projection 45 is also guided to the holding hole 22. When the illuminating device 30 reaches the proper mounting position, as shown in FIG. 7, the holding projection 42 fits into the holding hole 22 and is locked in the vertical direction with respect to the edge of the holding hole 22. The lighting device 30 is fixed to the console body 20. Further, as shown in FIG. 9, the restriction projection 45 is fitted into the holding hole 22 to restrict the opening of the lower edge 44 of the cover lens 35. As a result, the light guide 34 and the reflecting member 43 are integrated and are sandwiched between the facing wall 38 of the design surface panel 32 and the cover lens 35, and can move in the vertical direction and the vehicle width direction. It is regulated and held at the proper mounting position.

  As described above, according to the present embodiment, the upper and lower insertion pieces 39, 48 are inserted into the upper and lower insertion holes 39, 50 from the vehicle width direction, and are engaged with each other in the vehicle width direction. Therefore, it is possible to restrict the cover lens 35 from being removed not only in the vehicle width direction but also in a direction intersecting with the vehicle width direction (vertical direction, vehicle longitudinal direction, etc.). Therefore, it is possible to avoid scattering of the edged member such as the cover lens 35 into the vehicle interior.

  Further, a restriction protrusion 45 is provided on the lower edge 44 of the cover lens 35, and the restriction protrusion 45 is fitted into the holding hole 22 from above and below, and the restriction protrusion 45 and the inner wall of the holding hole 22 are arranged in the vehicle width direction. Since they are brought into contact with each other and engaged, it is possible to restrict the cover lens 35 from coming off in the vehicle width direction, and the cover lens 35 from coming off while rotating around the light guide 34. Furthermore, since the cover lens 35 is attached not only to the design surface panel 32 but also to the console main body 20, scattering into the vehicle compartment can be reliably regulated.

<Embodiment 2>
Next, Embodiment 2 of the present invention will be described with reference to the drawing of FIG. In the present embodiment, the configuration of the restricting protrusion 45 in the first embodiment is partially changed. The same components as those in the first embodiment are denoted by the same reference numerals, and the configurations and operations overlapping with those in the first embodiment. Description of effects and effects will be omitted. That is, the restricting protrusion 51 of the present embodiment includes a contact portion 52 that contacts the inner wall of the holding hole 22 in the vehicle width direction, and a protrusion that vertically locks against the hole edge of the holding hole 22. 53. The restricting protrusion 45 of the first embodiment is configured to include only the contact portion 52 of the present embodiment, and the difference between the restricting protrusions 45 and 51 is the presence or absence of the protrusion 53. For this reason, the engagement by the restriction protrusion 51 of the second embodiment is stronger than the engagement by the restriction protrusion 45 of the first embodiment.
