DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings used in the following description, the dimensions of the components may be shown at different scales to make them easier to see, and the dimensional ratios of the components may not necessarily be the same as in reality.

[0010] Additionally, XYZ coordinates are shown in each figure as appropriate. The Y axis is the front-to-rear direction (first direction) of the vehicle on which the vehicle lamp is mounted, with the +Y side (first side) being the front side and the -Y side (second side) opposite the +Y side being the rear side. The X axis direction is the left-to-right direction (second direction) of the vehicle, with the +X side being the right side and the -X side being the left side. The Z axis direction is the vertical direction, with the +Z side being the upper side and the -Z side being the lower side.

[0011] FIG. 1 is an exploded perspective view of a vehicle lamp 100 according to the present embodiment. The vehicular lamp 100 of this embodiment is applied to a vehicular headlamp mounted on the front of a vehicle, for example, and is applied to a headlamp as an example. In the following explanation, the vehicular lamp 100 mounted on the left side (-X) of the vehicle out of a pair of headlights mounted on the vehicle will be described. Note that the vehicular lamp 100 mounted on the right side (+X) of the vehicle out of a pair of headlights has a configuration that is inverted in the left-right direction X from the following explanation.

[0012] The vehicle lamp 100 of this embodiment includes a housing 10, a light source device 20, an extension (second member) 30, and an outer lens (first member) 40. The vehicle lamp 100 of this embodiment also includes an inner lens and a reflector, which are not shown.

[0013] The vehicle lamp 100 has a structure in which a light source device 20, an extension 30, as well as a reflector and an inner lens (not shown) are arranged in a lamp chamber A composed of a housing 10 with an opening on the +Y side and a transparent outer lens 40 covering the opening of the housing 10.

[0014] The housing 10 is a main body member of the vehicle lamp 100, and is formed so as to be able to hold the light source device 20, extension 30, outer lens 40, and an inner lens and reflector (not shown) that are provided in the vehicle lamp 100 at predetermined positions within the lamp chamber A. Light emitted from the light source device 20 travels substantially parallel to the front-rear direction Y. In other words, the front-rear direction Y is an example of the optical axis direction.

[0015] The housing 10 has a light source support portion 12 and a housing outer edge portion 13. The housing 10 opens to the front side (+Y). The housing 10 covers the lamp chamber A from the rear side (-Y) and from the front, rear, left and right. The light source support portion 12 protrudes to the front from the housing 10. The light source device 20 is fixed to the surface of the light source support portion 12 facing the front side (+Y).

[0016] The housing outer edge portion 13 is provided on the outer edge of the opening of the housing 10. The housing outer edge portion 13 is located at the front (+Y) end of the housing 10. The outer lens 40 is fixed to the housing outer edge portion 13. The fixing structure between the housing 10 and the outer lens 40 will be described in detail later.

[0017] The extension 30 and the outer lens 40 are fixed to each other to form a semi-assembled unit 50. That is, the semi-assembled unit 50 has the extension 30 and the outer lens 40. In this embodiment, the extension 30 and the outer lens 40 are fixed to each other by a plurality of fixing screws 9. The extension 30 is fixed to the outer lens 40 from the rear side (-Y). Furthermore, the outer lens 40 is fixed to the housing 10 from the front side (+Y).

[0018] The extension 30 has a light source opening 31a that penetrates in the front-rear direction Y, multiple fixing holes 31b that penetrate in the front-rear direction Y, and multiple engagement pieces 32. The extension 30 has a shape that combines plate-like portions having surfaces facing in various directions. The light source opening 31a overlaps the light source device 20 when viewed from the front-rear direction Y. The optical axis of the light source device 20 passes through the light source opening 31a. Light emitted from the light source device 20 passes through the light source opening 31a and is irradiated to the front side (+Y). A fixing screw 9 is inserted into each of the multiple fixing holes 31b.

[0019] The extension 30 is formed with a design surface 31f facing the front side (+Y). The design surface 31f is visible from the front side (+Y) through the outer lens 40. The extension 30 is housed inside the lamp chamber A and covers the housing 10 from the front side (+Y). In this way, the extension 30 adds design features to the vehicle lamp 100.

[0020] The multiple engagement pieces 32 are provided on the outer edge of the extension 30. In FIG. 1, only three of the multiple engagement pieces 32 that protrude upward from the upper end of the extension 30 are shown. However, the multiple engagement pieces 32 also include two or more engagement pieces 32 that protrude downward from the lower end of the extension 30. The engagement pieces 32 are used to position the extension 30 and the outer lens 40 when they are fixed together. The positioning structure between the engagement pieces 32 and the outer lens 40 will be described in detail later.

[0021] The outer lens 40 is made of a translucent resin material. The outer lens 40 transmits light emitted from the light source device 20. The portions of the outer lens 40 other than the light-emitting portion may be colored with an opaque coloring material, coloring agent, or the like, or may be molded in two colors together with the light-emitting portion using opaque PMMA acrylic resin.

[0022] The outer lens 40 has an outer lens outer edge portion 43. The outer lens 40 covers the lamp chamber A from the front side (+Y). The outer lens 40 is provided with a plurality of screw holes 41b that open to the rear side (-Y). Fixing screws 9 for fixing the extension 30 to the outer lens 40 are fastened into the screw holes 41b.

[0023] The outer lens outer edge portion 43 is provided on the outer edge of the outer lens 40 when viewed from the front-rear direction Y. The outer lens outer edge portion 43 is located at the rear (-Y) end of the outer lens 40. The outer lens 40 is fixed to the housing 10 at the outer lens outer edge portion 43.

[0024] A specific description will be given of the fixing structure between the housing 10 and the outer lens 40. In the following description, in the connecting portion between the housing 10 and the outer lens 40 (i.e., the housing outer edge portion 13 and the outer lens outer edge portion 43), the side closer to the lamp chamber A will be referred to as the "inside of the housing," and the side away from the lamp chamber A will be referred to as the "outside of the housing."

[0025] Fig. 2 is a perspective view showing the housing outer edge portion 13, the outer lens outer edge portion 43, and the engagement piece 32 in an exploded state. Fig. 3 is a cross-sectional view of the vehicle lamp 100 taken along line III-III in Fig. 2, showing the housing outer edge portion 13, the outer lens outer edge portion 43, and the engagement piece 32 in an assembled state. Figs. 2 and 3 show the region of the fixing structure between the housing 10 and the outer lens 40 that is located above the lamp chamber A.

[0026] As shown in FIG. 2 , the housing outer edge portion 13 has a first rib 15 and a second rib 16. The first rib 15 and the second rib 16 protrude toward the rear (-Y) side. The first rib 15 and the second rib 16 extend parallel to each other in a direction perpendicular to the front-rear direction Y. A groove 17 is formed between the first rib 15 and the second rib 16. The groove 17 extends together with the first rib 15 and the second rib 16 in a direction perpendicular to the front-rear direction Y. The first rib 15, the second rib 16, and the groove 17 are provided over the entire length of the housing outer edge portion 13.

[0027] 2, the first rib 15 is disposed on the inner side of the housing relative to the second rib 16. The first rib 15 and the second rib 16 extend in the left-right direction X. That is, the first rib and the second rib 16 extend in the left-right direction X on at least a portion of the housing outer edge portion 13.

[0028] The first rib 15 has a notch 15a recessed toward the rear side (-Y). The depth of the notch 15a in the front-rear direction Y is approximately half the dimension of the first rib 15 in the front-rear direction Y. The width dimension of the notch 15a in the left-right direction X gradually increases toward the front side (+Y) of the notch 15a.

[0029] The second rib 16 is provided with a locking hole 16h that penetrates in the thickness direction of the second rib 16 (i.e., the vertical direction Z in FIG. 2). The locking hole 16h is an elongated hole that extends in the direction in which the second rib 16 extends (i.e., the horizontal direction X).

[0030] 2, the outer lens outer edge portion 43 has a fixing rib 45, a plurality of locking protrusions 46, and a plurality of positioning protrusions 47. The fixing rib 45 is provided over the entire length of the outer lens outer edge portion 43. Meanwhile, the plurality of locking protrusions 46 and the plurality of positioning protrusions 47 are discretely arranged over the entire length of the outer lens outer edge portion 43.

[0031] The fixing rib 45 protrudes rearward (-Y) and extends in a direction perpendicular to the front-rear direction Y. When viewed from the front-rear direction Y, the fixing rib 45 overlaps with the groove 17 of the housing outer edge portion 13. As shown in FIG. 3 , the fixing rib 45 is inserted into the groove 17. The tip of the fixing rib 45 faces the bottom surface 17b of the groove 17 across a gap. The groove 17 is filled with adhesive 3. The adhesive 3 is injected into the groove 17 in an uncured state. Furthermore, the adhesive 3 comes into contact with the surface of the fixing rib 45 when the fixing rib 45 is inserted into the groove 17. When the adhesive 3 hardens, the outer lens 40 is fixed to the housing outer edge portion 13.

[0032] As shown in FIG. 2, the locking protrusion 46 protrudes toward the outside (upper side) of the housing from the surface of the fixing rib 45 facing the outside of the housing (upper side in FIG. 2). The locking protrusion 46 extends along the left-right direction X. The locking protrusion 46 has a riding surface 46a facing the rear side (-Y) and a locking surface 46b facing the front side (+Y). The riding surface 46a is a flat surface that slopes toward the rear side (-Y) as it approaches the outside (upper side) of the housing. The locking surface 46b is a flat surface that is perpendicular to the front-rear direction Y.

[0033] As shown in FIG. 3, the locking protrusion 46 is inserted into the locking hole 16h of the housing 10. The assembly process for the vehicle lamp 100 includes a step of moving the outer lens 40 rearward (−Y) toward the housing 10 and inserting the fixing rib 45 into the groove 17. During the insertion step, the riding surface 46a of the locking protrusion 46 comes into contact with the front end 16a of the second rib 16. When the outer lens 40 is further moved rearward (−Y), the front end 16a of the second rib 16 rides up the riding surface 46a, and the second rib 16 is elastically deformed toward the outside of the housing (upward in FIG. 3). When the outer lens 40 is further moved rearward (−Y) until the locking protrusion 46 reaches the locking hole 16h, the locking protrusion 46 is inserted into the locking hole 16h. When the insertion step is completed, the locking surface 46b of the locking protrusion 46 is locked to the front (+Y) edge of the locking hole 16h. This prevents the outer lens 40 from coming off the housing 10 before the adhesive 3 hardens. Preferably, the second rib 16 is provided with notches located on both sides of the locking hole 16h in the left-right direction X. In this case, the second rib is more likely to elastically deform in the up-down direction around the locking hole 16h.

[0034] As shown in FIG. 2, the positioning protrusion 47 is located more inward in the housing than the fixing rib 45. The positioning protrusion 47 protrudes rearward (-Y) and extends along the left-right direction X. The dimension of the positioning protrusion 47 in the front-rear direction Y is smaller than the dimension of the fixing rib 45 in the front-rear direction Y. As shown in FIG. 3, the positioning protrusion 47 is located below the first rib 15 of the housing 10. The opening dimension of the positioning hole 32h in the up-down direction Z gradually decreases toward the rearward (-Y) side.

[0035] As shown in Figure 2, the engagement piece 32 protrudes from the extension 30 toward the outside of the housing (upward in Figure 2). The engagement piece 32 is plate-shaped and extends along a plane perpendicular to the front-rear direction Y. The extension 30 has a positioning hole 32h, a contact protrusion 33, and an insertion convex portion 34.

[0036] The positioning hole 32h penetrates the engagement piece 32 in the front-rear direction Y. The positioning hole 32h is an elongated hole extending in the left-right direction X. As shown in FIG. 3 , the positioning protrusion 47 of the outer lens 40 is inserted into the positioning hole 32h. As described above, the positioning protrusion 47 has a tapered shape in which the dimension in the up-down direction Z decreases toward the tip. This makes it easy to insert the positioning protrusion 47 into the positioning hole 32h when assembling the extension 30 to the outer lens 40 from the rear side (-Y). In this embodiment, a portion of the upper surface of the positioning protrusion 47 contacts or faces a portion of the inner surface of the positioning hole 32h facing downward via a small gap. As a result, downward movement of the extension 30 is restricted by the outer lens 40.

[0037] As shown in FIG. 2, the contact protrusion 33 protrudes from the end face of the engagement piece 32 facing the outside of the housing (upper side in FIG. 2) toward the outside of the housing. When viewed from the front-rear direction Y, the contact protrusion 33 has an isosceles triangular shape with a tip 33a located on the outside of the housing as its vertex. As shown in FIG. 3, when the extension 30 is attached to the outer lens 40, the tip 33a of the contact protrusion 33 comes into contact with the lower surface of the fixing rib 45. As a result, the outer lens 40 restricts the upward movement of the extension 30.

[0038] According to this embodiment, by inserting the positioning protrusion 47 into the positioning hole 32h, the upper surface of the positioning protrusion 47 comes into contact with the inner surface of the positioning hole 32h or faces the inner surface of the positioning hole 32h with a small gap therebetween, and the tip 33a of the contact protrusion 33 comes into contact with the fixing rib 45. This makes it possible to position the extension relative to the outer lens 40 in the up-down direction Z, and simplifies the process of fixing the extension 30 to the outer lens 40 using the fixing screw 9.

[0039] As shown in FIG. 2, the insertion protrusion 34 protrudes toward the rear side (-Y) from the surface of the engagement piece 32 facing the rear side (-Y). The insertion protrusion 34 is located above the positioning hole 32h. The insertion protrusion 34 is plate-shaped with its thickness direction in the vertical direction Z. The insertion protrusion 34 has a trapezoidal shape whose dimension in the left-right direction X decreases toward the rear side (-Y) when viewed from the vertical direction Z.

[0040] As shown in FIG. 3, the insertion protrusion 34 is inserted into the notch 15a of the first rib 15. As a result, the notch 15a is blocked by the insertion protrusion 34 when viewed from the up-down direction Z. The rear (-Y) end of the insertion protrusion 34 faces the bottom portion (portion facing the front) of the notch 15a in the front-rear direction Y with a slight gap between them. The insertion protrusion side surface 34f of the insertion protrusion 34 facing the outside of the housing (upper side in FIG. 3) is located closer to the inside of the housing (lower side in FIG. 3) than the rib side surface 15f of the first rib 15 facing the outside of the housing (upper side). Therefore, by inserting the insertion protrusion 34 into the notch 15a, a recess 8 is formed on the inner surface of the groove 17, recessed toward the inside of the housing (lower side) relative to the rib side surface 15f.

[0041] A portion of the adhesive 3 filled in the groove 17 enters the recess 8. That is, the adhesive 3 is filled into the recess 8. The adhesive 3 hardens to fix the insertion protrusion 34 and the first rib 15 relative to each other. That is, the extension 30 is fixed to the housing 10 by the adhesive 3.

[0042] Next, a method for manufacturing the vehicle lamp 100 of this embodiment will be described. The manufacturing method of the vehicle lamp 100 of this embodiment includes at least a semi-assembled assembly step, an adhesive injection step, an insertion step, and a curing step. In addition to the above steps, the manufacturing method of the vehicle lamp 100 may also include a step of fixing a reflector (not shown) and a step of fixing an inner lens (not shown), etc.

[0043] The semi-assembled product assembling process is a process of fixing the extension 30 to the outer lens 40 from the rear side (-Y) to manufacture the semi-assembled product 50 shown in FIG. 1. In the semi-assembled product assembling process, first, the multiple positioning protrusions 47 of the outer lens 40 shown in FIG. 3 are inserted into the positioning holes 32h of the extension 30, respectively. This positions the extension 30 and the outer lens 40 relative to each other. Next, the fixing screws 9 shown in FIG. 1 are inserted into the fixing holes 31b of the extension 30 and screwed into the screw holes 41b of the outer lens 40. This manufactures the semi-assembled product 50.

[0044] The adhesive injection step is a step of injecting uncured adhesive 3 into the groove 17. The amount of adhesive 3 injected into the groove 17 is adjusted to a constant amount by a dispenser. As described above, the groove 17 is provided over the entire length of the housing outer edge portion 13. The adhesive 3 is injected over the entire length of the groove 17.

[0045] The insertion process is a process of assembling the semi-assembled unit 50 into the housing 10. In the insertion process, the fixing rib 45 of the outer lens 40 is inserted into the groove 17 of the housing 10. As shown in FIG. 2, the insertion convex portion 34 of the extension 30 faces the cutout portion 15a provided in the first rib 15 of the housing 10 in the front-rear direction Y. Therefore, as shown in FIG. 3, when the fixing rib 45 is inserted into the groove 17 in the insertion process, the insertion convex portion 34 is inserted into the cutout portion 15a. As a result, a recess 8 that is recessed relative to the rib side surface 15f is formed on the inner surface of the groove 17.

[0046] As shown in FIG. 3, the uncured adhesive 3 injected into the groove 17 spreads along the surface of the fixing rib 45 as the fixing rib 45 is inserted into the groove 17. Some of the uncured adhesive 3 flows toward the outside of the housing relative to the fixing rib 45 (upper side in FIG. 3), and another part flows toward the inside of the housing relative to the fixing rib 45 (lower side in FIG. 3). The part of the uncured adhesive 3 that flows toward the inside of the housing relative to the fixing rib 45 flows into the recess 8 located below the fixing rib 45. Also, in the insertion process, the locking protrusion 46 of the outer lens 40 is inserted into the locking hole 16h of the housing 10. This makes it less likely that the outer lens 40 and the housing 10 will become misaligned relative to each other in the curing process described below.

[0047] The curing process is a process of hardening the adhesive 3. If the adhesive 3 is of a type that becomes effective through the evaporation of water or a solvent, for example, the curing process is a process of waiting until the evaporation of the water or solvent contained in the adhesive 3 is complete. If the adhesive 3 is an ultraviolet-curable adhesive, the curing process is a process of irradiating the adhesive 3 with ultraviolet light through the outer lens 40. When the curing process is complete, the outer lens 40 and the extension 30 are each fixed to the housing 10.

[0048] <Summary of the embodiment>

[0049] According to the configuration described above, by fixing the extension 30 and the housing 10 with the adhesive 3, the extension 30 and the housing 10 are less likely to collide or rub against each other even if vibration occurs in the extension 30. This reduces noise generated by the vehicle lamp 100 and also reduces damage to the components of the vehicle lamp 100.

[0050] Furthermore, according to the configuration described above, by inserting the positioning protrusion 47 into the positioning hole 32h, it becomes easier to position the extension 30 on the outer lens 40. Furthermore, by providing the insertion convex portion 34 on the engagement piece 32 in which the positioning hole 32h is provided, it becomes easier to prevent the insertion convex portion 34 from shifting in position relative to the housing 10, and it becomes possible to smoothly insert the insertion convex portion 34 into the cutout portion 15a.

[0051] Furthermore, according to the configuration described above, the outer lens 40 and the housing 10 are fixed to each other by the adhesive 3, and part of this adhesive 3 can be used to fix the extension 30 and the housing 10. Therefore, there is no need to inject adhesive 3 into each location, and the manufacturing method of the vehicle lamp 100 can be simplified.

[0052] Furthermore, according to the configuration described above, it is possible to increase the number of fixing points of the extension 30 without adding any additional processes, thereby suppressing vibration of the extension 30. This reduces vibration of the extension 30, and suppresses noise and damage when the extension 30 comes into contact with other members.

[0053] Furthermore, according to the configuration described above, the extension 30 is supported from both sides in the first direction (front-rear direction Y). This allows the extension 30 to be firmly fixed, and vibration of the extension 30 can be effectively suppressed.

[0054] Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the specific embodiments, and various modifications and variations are possible within the scope of the gist of the present invention as set forth in the claims. Furthermore, the components of multiple embodiments can be combined as appropriate.

[0055] For example, in the above-described vehicle lamp 100, the outer lens 40 is exemplified as the first member fixed to the housing 10, and the extension 30 is exemplified as the second member fixed to the first member. However, the configurations of the first member and the second member are not limited to this embodiment. As an example, the first member may be an inner lens, a reflector, or an extension, and the second member may be an inner lens or a reflector.

[0056] In addition, in the above-described embodiment, a headlight is given as an example of a vehicle lamp according to the present invention, but the vehicle lamp according to the present invention may also be applied to daytime running lights (DRLs), stop lamps, tail lamps, etc.

[0057] In the above-described embodiment, the description of the inner lens and reflector provided in the vehicle lamp has been omitted. The inner lens and reflector may be fixed to the extension, the housing, or the outer lens. The inner lens and reflector may constitute one part of a semi-assembled product. [Explanation of symbols]
