DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the drawings used in the following description, in order to make each component easier to see, the dimensions of the components may be shown at different scales, and the dimensional ratios of each component may not necessarily be the same as in reality.

[0013] As one embodiment of the present invention, a vehicle lamp 1 having a mounting structure shown in, for example, Figs. 1 to 5 will be described.

[0014] Fig. 1 is a front view showing a vehicle lamp 1 equipped with the mounting structure of this embodiment. Fig. 2 is a cross-sectional perspective view showing the mounting structure taken along line AA shown in Fig. 1. Fig. 3 is a perspective view of the mounting structure shown in Fig. 1 as seen from the rear side. Fig. 4 is an enlarged perspective view of the mounting structure of this embodiment. Fig. 5 is a perspective view showing the mounting structure of this embodiment with the inner lens 3 removed from the extension 2.

[0015] In addition, in the drawings shown below, an XYZ Cartesian coordinate system is set up, with the X-axis direction representing the front-to-rear direction (length direction) of the vehicle lighting fixture 1, the Y-axis direction representing the left-to-right direction (width direction) of the vehicle lighting fixture 1, and the Z-axis direction representing the up-down direction (height direction) of the vehicle lighting fixture 1.

[0016] As shown in Figures 1 and 2, the vehicle lamp 1 of this embodiment has a structure in which an extension 2 serving as a first member and an inner lens 3 serving as a second member are arranged inside a lamp body 4.

[0017] In addition, although not shown, the vehicle lamp 1 of this embodiment has a structure in which, in addition to the above-mentioned extension 2 and inner lens 3, components such as a light source, reflector, bracket, etc. are arranged inside the lamp body 4, and these components are attached to the inside of the lamp body 4.

[0018] The lamp body 4 is composed of a housing 5 with an opening on the front side and a transparent outer lens (not shown) that covers the opening of the housing 5. The shape of the lamp body 4 can be changed as appropriate to match the design of the vehicle lamp 1, etc.

[0019] The extension 2 is attached to the front side of the housing 5. The inner lens 3 is attached to the rear side of the extension 2 and disposed between the extension 2 and the front side of the housing 5.

[0020] Specifically, in order to attach the extension 2 to the front side of the housing 5, the extension 2 has a boss 22 that protrudes cylindrically from the surface facing the housing 5 on the rear side, and a screw hole 23 into which a screw (not shown) is screwed at the tip of the boss 22.

[0021] The periphery of the base end side of the boss 22 is provided so as to protrude in a rectangular shape from the rear surface side of the extension 2. The periphery of the base end side of the boss 22 is not limited to the rectangular shape described above, and the protruding shape can be changed as appropriate.

[0022] Meanwhile, the housing 5 has a hole 5a at a position facing the boss 22. The extension 2 is attached to the front side of the housing 5 by screwing a screw into a screw hole 23 provided at the tip of the boss 22 through the hole 5a.

[0023] As shown in Figs. 1 to 5, a vehicle lamp 1 of this embodiment includes a mounting structure of this embodiment for mounting an inner lens 3, which is a second member, to an extension 2, which is a first member.

[0024] Specifically, the mounting structure of this embodiment has a locking recess 21 provided in the extension 2 and a locking protrusion 31 provided in the inner lens 3 to be locked in the locking recess 21 .

[0025] The locking recess 21 is provided in a side wall 2a along the direction in which the inner lens 3 of the extension 2 is attached, which is located on the base end side of the boss 22. The locking recess 21 in this embodiment is formed by a hole portion penetrating the side wall 2a.

[0026] On the other hand, the locking protrusion 31 is provided protruding from the surface facing the side wall 2a of the inner lens 3. The locking protrusion 31 in this embodiment is composed of a claw portion protruding from the surface of the inner lens 3 facing the side wall 2a.

[0027] The locking recess 21 is not necessarily limited to the above-mentioned hole shape, and may have any shape that allows the locking protrusion 31 to be locked, such as a hole that does not penetrate the side wall 2a. On the other hand, the locking protrusion 31 is also not limited to a shape like the above-mentioned claw portion, and may have any shape that allows the locking recess 21 to be locked. In other words, the locking recess 21 and the locking protrusion 31 are not limited to a configuration in which a claw portion is locked in the above-mentioned hole, and may have any configuration in which the locking protrusion 31 can be locked in the locking recess 21.

[0028] The inner lens 3 is provided with a cutout recess 32 cut along the periphery of the base end side of the boss 22. The locking protrusion 31 is disposed at a position along the periphery of this cutout recess 32.

[0029] The cutout recess 32 is formed by cutting out the inner lens 3 in a rectangular shape in accordance with the rectangular protruding shape of the base end side of the boss 22 described above.

[0030] In the mounting structure of this embodiment having the above-described configuration, when attaching the inner lens 3 to the rear side of the extension 2, the inner lens 3 is slid forward from the rear side of the extension 2 along the side wall 2a of the extension 2.

[0031] At this time, the notched recess 32 is disposed so as to surround the periphery of the base end side of the boss 22, and the locking protrusion 31 on the inner lens 3 side is locked in the locking recess 21 on the extension 2 side.

[0032] This makes it possible to attach the inner lens 3 to the rear side of the extension 2. Moreover, the extension 2 is attached to the front side of the housing 5 with the inner lens 3 attached to the rear side.

[0033] As described above, in the mounting structure of this embodiment, it is possible to stably mount the inner lens 3 to the back side of the extension 2 without using fixing means such as bosses, screw holes, or screws for mounting the inner lens 3 to the back side of the extension 2.

[0034] Furthermore, with the mounting structure of this embodiment, even if there is not enough space to provide a boss between the front side of the housing 5 and the rear side of the extension 2, it is possible to mount the extension 2 to the front side of the housing 5 with the inner lens 3 attached to the rear side of the extension 2.

[0035] As a result, in the mounting structure of this embodiment, it is possible to properly mount the inner lens 3 on the back side of the extension 2 while saving space and without increasing the number of parts required for the above-mentioned fixing.

[0036] The present invention is not necessarily limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0037] For example, the mounting structure to which the present invention is applied is not necessarily limited to the configuration in which the inner lens 3, which is the second member, is mounted to the extension 2, which is the first member, described above.

[0038] For example, the present invention can be widely applied to structures in which a second member is attached to a first member placed inside a lamp body, such as a configuration in which a heat shield plate, which is a second member, is attached to a reflector, which is a first member.

[0039] Furthermore, the mounting structure to which the present invention is applied is not limited to a mounting structure for a component placed within a front-side lamp body such as a headlamp, but may also be a mounting structure for a component placed within a rear-side lamp body such as a rear combination lamp.
