[0001] The present disclosure relates to a lamp unit mounting structure and a lamp unit mounting method. [Background technology]

[0002] A vehicle lamp (side mirror) is known that includes a mirror body (mirror cover) and a lamp unit that is arranged with a part of an outer lens inserted from the rear side into an opening formed in the mirror body (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2023-045610 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the vehicle lamp described in Patent Document 1 has a problem in that the lamp unit cannot be attached to the mirror body from the front side.

[0005] The present disclosure has been made to solve such problems, and aims to provide a lamp unit mounting structure and a lamp unit mounting method that enable the lamp unit to be mounted to an object to which the lamp unit is to be mounted (e.g., a mirror body) from the front side. [Means for solving the problem]

[0006] The lamp unit mounting structure according to the present disclosure includes a lamp unit, and a lamp unit mounting counterpart having a recess recessed from the front side toward the rear side, into which the lamp unit is inserted from the front side. The lamp unit includes a housing including a housing main body and a housing side flange portion protruding outward from an open end of the housing main body, a light-transmitting cover main body, and a light-transmitting cover side flange portion disposed behind an outer periphery of the light-transmitting cover main body in a front view, and a light-transmitting cover that forms a lamp chamber between the housing main body and the light-transmitting cover side flange portion and the housing side flange portion are joined together, and a light-transmitting cover that is disposed within the lamp chamber and has a light-transmitting cover side flange portion and a light-transmitting cover side flange portion disposed within the lamp chamber. and an optical system that irradiates light that passes through a bar, and the annular joint formed by joining the translucent cover side flange portion and the housing side flange portion includes a pair of joint portions facing each other across the lamp chamber, one of the pair of joint portions is positioned rearward of the other joint portion, and a space is formed in the inner wall of the recess into which the one joint portion is inserted, and the lamp unit is attached to a mating part of the lamp unit with the one joint portion inserted into the space formed in the inner wall of the recess and the translucent cover main body inserted into the open end of the recess to close the open end of the recess.

[0007] With this configuration, the lamp unit can be attached to a mounting object (for example, a mirror body) from the front side.

[0008] This is because, first, the part into which the lamp unit is attached has a recess that is recessed from the front side toward the rear side, so that the lamp unit is inserted from the front side; second, one joint part is positioned rearward of the other joint part; and third, a space is formed on the inner wall of the recess formed in the part into which the lamp unit is attached, so that one joint part can be inserted.

[0009] In the above-mentioned lighting unit mounting structure, the one joint portion may be inserted into a space formed in an inner wall of the recess, and the light-transmitting cover main body may be inserted into an opening end of the recess to close the opening end of the recess, and a fixing means may be further provided for fixing the lighting unit inserted into the recess to a mating part of the lighting unit.

[0010] The lamp unit mounting structure may further comprise a first positioning means for positioning the lamp unit relative to the mounting partner of the lamp unit with respect to an insertion direction of the lamp unit.

[0011] The above lamp unit mounting structure may further comprise a second positioning means for positioning the lamp unit relative to the mounting partner of the lamp unit in the up, down, left and right directions.

[0012] In the above lamp unit mounting structure, the lamp unit may be mounted on a mirror body, a cowl, or a bumper.

[0013] In the above lamp unit mounting structure, the space may be a notch, a recess, or a through hole.

[0014] A lamp unit mounting method according to the present disclosure is a method for mounting a lamp unit to a lamp unit mounting partner having a recess recessed from the front side to the rear side, into which the lamp unit is inserted from the front side, the lamp unit including a housing including a housing main body and a housing side flange portion protruding outward from an open end of the housing main body, a light-transmitting cover main body, and a light-transmitting cover side flange portion arranged behind an outer periphery of the light-transmitting cover in a front view, the light-transmitting cover forming a lamp chamber between the housing main body and the light-transmitting cover side flange portion and the housing side flange portion by joining the light-transmitting cover side flange portion and the housing side flange portion, and an optical system arranged within the lamp chamber and irradiating light transmitted through the light-transmitting cover, The annular joint portion joining the light cover side flange portion and the housing side flange portion includes a pair of joint portions facing each other across the lamp chamber, one of the pair of joint portions is positioned rearward of the other joint portion, and a space is formed in the inner wall of the recess into which the one joint portion is inserted, and the method includes the steps of inserting the lamp unit into the recess from the front side until the other joint portion abuts against an opening end of the recess, moving the lamp unit toward the space until the one joint portion is inserted into the space formed in the inner wall of the recess, and further inserting the lamp unit into the recess until the light-transmitting cover main body is inserted into the opening end of the recess and blocks the opening end of the recess.

[0015] With this configuration, the lamp unit can be attached to a mounting object (for example, a mirror body) from the front side.

[0016] This is because, first, the part into which the lamp unit is attached has a recess that is recessed from the front side toward the rear side, so that the lamp unit is inserted from the front side; second, one joint part is positioned rearward of the other joint part; and third, a space is formed on the inner wall of the recess formed in the part into which the lamp unit is attached, so that one joint part can be inserted.

As shown in Fig. 3, the outer lens body 121 is arranged in a state in which its upper portion is inclined backward in a vertical cross section. Also, as shown in Fig. 4, the outer lens body 121 is configured in a shape curved backward as it goes outward in the vehicle width direction in a horizontal cross section.

[0029] Outer lens flange F 12 is the upper flange part F 12a (See Figure 3), inner flange F 12c (See Figure 4) Upper flange part F 12a The inner flange portion F protrudes from a region along the upper oblique side portion 12a of the outer periphery of the rear surface of the outer lens 12 toward the housing 11 (rear side of the vehicle) (see FIG. 3). 12cprotrudes toward the housing 11 (rear of the vehicle) from a region along the inner oblique side portion 12c of the outer periphery of the rear surface of the outer lens 12 (see FIG. 4).

[0030] In addition, the outer lens flange F 12 is the lower flange part F 12b (See Figure 3 and Figure 6) Outer flange part F 12d (See Figure 6) and connecting flange F 12e (not shown) The lower flange part F 12b The extension portion E extends from the area along the lower oblique side portion 12b of the outer peripheral portion of the back surface of the outer lens 12 toward the housing 11 side (the rear side of the vehicle). 12b On the other hand, the outer flange portion F 12d The extension portion E extends from a region along the outer oblique side portion 12d of the outer peripheral portion of the back surface of the outer lens 12 toward the housing 11 side (the rear side of the vehicle). 12d (See FIG. 6.) Although not shown, the connecting flange portion F 12e is an extension portion E extending from a region along the connecting side portion 12e of the outer periphery of the back surface of the outer lens 12 toward the housing 11 side (the rear side of the vehicle). 12e It is provided at the tip of the.

[0031] As shown in Figure 3, the lower flange F 12b In the vertical section, the upper flange part F 12a It is located a distance L1 toward the rear of the vehicle.

[0032] FIG. 6 is a perspective view of the lamp unit 10. As shown in FIG.

[0033] As shown in Figure 6, the extension E 12b The width L2 (between the lower oblique side portion 12b and the lower flange portion F 12b 3 and 6) is approximately constant between one end and the other end of the lower oblique side portion 12b (see the range indicated by reference symbol A1 in FIG. 1).

[0034] On the other hand, extension E 12d Width L3 (between outer oblique side 12d and outer flange F12d The distance between the outer oblique side portion 12d and the outer oblique side portion 12c (see the range indicated by the reference symbol A2 in FIG. 1) is not constant between one end and the other end of the outer oblique side portion 12d, but gradually narrows from the one end side (the lower end side in FIG. 1 and FIG. 6) to the other end side (the upper end side in FIG. 1 and FIG. 6). 12e The width L4 (between the connecting side portion 12e and the connecting flange portion F 12e The distance between the connecting edge 12e and the other end (see the range indicated by the symbol A3 in FIG. 1) is not constant between one end and the other end of the connecting edge 12e, but gradually narrows from the one end side (lower end side) of the connecting edge 12e to the other end side (upper end side).

[0035] Above upper flange part F 12a , Lower flange part F 12b , inner flange part F 12c , outer flange part F 12d and connecting flange part F 12e are connected to each other, and the annular outer lens side flange portion F 12 It is composed of:

[0036] Next, the housing 11 will be described.

[0037] The housing 11 is made of an opaque resin. As shown in Fig. 3 and Fig. 4, the housing 11 includes a housing body 111 and a housing side flange portion F that protrudes outward from an opening end 111a of the housing body 111. 11 Including,

[0038] The housing body 111 includes an open end 111a disposed on the vehicle front side, a bottom portion 111b closing the vehicle rear side, and a cylindrical side wall 111c connecting the open end 111a and the bottom portion 111b.

[0039] Housing side flange F 11 is the upper flange part F 11a (See Figure 3) Lower flange part F 11b (See Figure 3), inner flange F 11c (See Figure 4) Outer flange part F 11d (See Figure 4) and connecting flange F11e (not shown).

[0040] Upper flange part F 11a The outer lens flange F 12 Upper flange part F 12a (See Fig. 3.) Similarly, the lower flange F 11b The outer lens flange F 12 Lower flange part F 12b (See Fig. 3.) Similarly, the inner flange part F 11c The outer lens flange F 12 Inner flange part F 12c (See Fig. 4) Similarly, the outer flange part F 11d The outer lens flange F 12 Outer flange part F 12d (See FIG. 4.) Although not shown, the connecting flange portion F 11e The outer lens flange F 12 Connection flange part F 12e is welded.

[0041] As shown in Figure 3, the lower flange F 11b In the vertical section, the upper flange part F 11a It is located a distance L1 toward the rear of the vehicle.

[0042] Above upper flange part F 11a , Lower flange part F 11b , inner flange part F 11c , outer flange part F 11d and connecting flange part F 11e are connected to each other, and the annular housing side flange portion F 11 It is composed of:

[0043] As shown in Figure 6, the housing flange F 11 The housing-side flange portion F is provided with a positioning rib R that abuts against an inner wall 21c of a recess 21 formed in the mirror body 20. The positioning rib R is 11A plurality of positioning ribs R (for example, four ribs R) are provided in the circumferential direction of the bearing. Note that only two positioning ribs R are shown in FIG.

[0044] The outer lens 12 and the housing 11 are connected to each other by an outer lens side flange portion F. 12 (All around) and housing flange F 11 (all around) are welded together (for example, vibration welding) to form the lamp chamber S1 (see Figures 3 and 4).

[0045] Outer lens flange F 12 (All around) and housing flange F 11 (entire periphery) are welded together to form an annular welded portion B (see Figs. 2 and 3). This annular welded portion B includes a pair of welded portions Ba, Bb (see Fig. 3) facing each other with the lamp chamber S1 in between.

[0046] 3, in the vertical cross section, of the pair of welded portions Ba and Bb, the lower welded portion Bb (an example of one welded portion of the present disclosure) is disposed on the rear side of the vehicle relative to the upper welded portion Ba (an example of the other welded portion of the present disclosure) disposed on the upper side. 11a and upper flange F 12a On the other hand, the lower welded part Bb is the lower flange part F 11b and the lower flange F 12b and are welded together.

[0047] Next, the optical system 13 will be described.

[0048] As shown in FIG. 3 and FIG. 4, the optical system 13 is disposed in a lamp chamber S1 constituted by the outer lens 12 and the housing 11. The optical system 13 may have any configuration as long as it is an optical system that irradiates light that passes through the outer lens 12 and functions as a turn lamp. For example, the optical system 13 may be a light source 13a (e.g., a semiconductor light-emitting element such as an LED) and an optical member 13b (e.g., a lens) that controls the light emitted by the light source 13a. The light source 13a may be one or more. Similarly, the optical member 13b may be one or more. The light source 13a is mounted on a substrate 13c and attached to, for example, the housing 11. Similarly, the optical member 13b is attached to, for example, the housing 11.

[0049] The lamp unit 10 having the above-mentioned configuration is inserted into a recess 21 formed in a mirror body 20 from the front side of the vehicle and attached to the mirror body 20.

[0050] The method for mounting this lamp unit will now be described.

[0051] Figures 7(a) to 7(d) are diagrams for explaining a method for mounting the lamp unit, and Figure 8 is a flowchart of the method for mounting the lamp unit.

[0052] First, the lamp unit 10 is inserted into the recess 21 from the front side of the vehicle until the upper welded part Ba (an example of the other welded part in this disclosure) abuts against the open end 21a of the recess 21 formed in the mirror body 20 (step S10, see Figs. 7(a) and 7(b)). The arrow Ar1 in Figs. 7(a) and 7(b) indicates the insertion direction (attachment direction) of the lamp unit 10. At that time, the lamp unit 10 is slid in the direction of the arrow Ar1 with the upper wall 111c1 of the housing 11 and the upper inner wall 21c1 of the recess 21 in contact with each other.

[0053] Next, the lamp unit 10 is moved toward the cutout portion S2 until the lower welded portion Bb (an example of one welded portion in the present disclosure) is inserted into the cutout portion S2 (an example of a space in the present disclosure) formed in the inner wall 21c (lower inner wall 21c2) of the recess 21 formed in the mirror body 20 (step S11, see FIG. 7(c)). An arrow Ar2 in FIG. 7(c) indicates the moving direction of the lamp unit 10.

[0054] Next, the lamp unit 10 is further inserted into the recess 21 until the outer lens body 121 is inserted into the opening end 21a of the recess 21 formed in the mirror body 20 and closes the opening end 21a of the recess 21 (step S12, see FIG. 7(d)). An arrow Ar3 in FIG. 7(d) indicates the insertion direction of the lamp unit 10. At that time, the lamp unit 10 is slid in the direction of the arrow Ar3 with the lower wall 111c2 of the housing 11 and the lower inner wall 21c2 of the recess 21 in contact with each other.

[0055] As described above, with the outer lens body 121 inserted into the open end 21a of the recess 21 formed in the mirror body 20 and closing the open end 21a of the recess 21, the bottom 111b (screw boss portion 111b1) of the housing 11 abuts against the bottom 21b of the recess 21 formed in the mirror body 20 (see FIG. 4). This positions the lamp unit 10 relative to the mirror body 20 (recess 21) in the insertion direction of the lamp unit 10. The bottom 111b (screw boss portion 111b1) of the housing 11 is an example of a first positioning means of the present disclosure.

[0056] At this time, although not shown, the housing side flange portion F 11 A positioning rib R (see FIG. 6) provided on the housing abuts against an inner wall 21c of a recess 21 formed in the mirror body 20. This positions the lamp unit 10 relative to the mirror body 20 (recess 21) in the up-down and left-right directions. This keeps the gap (all around) between the lamp unit 10 (outer lens main body 121) and the mirror body 20 (opening end 21a of the recess 21) uniform. This improves the appearance. Housing side flange portion F 11The positioning rib R provided on the is an example of the second positioning means of the present disclosure.

[0057] Next, the lamp unit 10 positioned as described above is fixed to the mirror body 20 (step S13). For example, a screw N1 (see FIG. 4) inserted into the bottom portion 21b of the mirror body 20 is screwed into the bottom portion 111b (screw boss portion 111b1) of the housing 11. The screw N1 is an example of a fixing means of the present disclosure.

[0058] In this manner, the lamp unit 10 can be attached to the mirror body 20. The lamp unit 10 can be removed from the mirror body 20 in the reverse order.

[0059] Next, the effect of the lamp unit mounting structure of the present embodiment configured as described above will be further described using a comparative example.

[0060] 9 is a diagram for explaining the effect of the lamp unit mounting structure of this embodiment, in which the left side shows the lamp unit mounting structure of this embodiment, and the right side shows a lamp unit mounting structure of a comparative example.

[0061] As shown in Fig. 9, in the lamp unit mounting structure of the comparative example, the lower welded portion Bb is disposed on the vehicle front side relative to the upper welded portion Ba. Other than that, it has the same configuration as the lamp unit mounting structure of the above embodiment. In contrast, in the lamp unit mounting structure of the present embodiment, the extension portion E 12b、 E 12d (See Figure 6) and extension E 12d (not shown), with the lower welded portion Bb being disposed rearward of the upper welded portion Ba. As a result, according to the lamp unit mounting structure of this embodiment, the vertical dimension of the lamp unit 10 (outer lens body 121) can be shortened by length L3 (see FIG. 9) compared to the lamp unit mounting structure of the comparative example, that is, the lamp unit 10 (outer lens body 121) can be made smaller in size in the vertical direction.

[0062] As described above, according to this embodiment, the lamp unit 10 can be attached to the mirror body 20 from the front side of the vehicle.

[0063] This is because, first, the mirror body 20 to which the lamp unit is attached is formed with a recess 21 recessed from the front side of the vehicle toward the rear side of the vehicle, into which the lamp unit 10 is inserted from the front side of the vehicle, second, the lower welded part Bb is disposed on the rear side of the vehicle than the upper welded part Ba, and third, the inner wall 21c (lower inner wall 21c2) of the recess 21 formed in the mirror body 20 is formed with a notch S2 into which the lower welded part Bb is inserted. That is, as a result of employing the above first to third points, it is possible to implement the lamp unit mounting method shown in FIG.

[0064] Next, a modified example will be described.

[0065] In the above embodiment, an example has been described in which the lamp unit 10 functioning as a turn lamp is used as the lamp unit, and the mirror body 20 is used as the mounting partner of the lamp unit, but this is not limited thereto. For example, a lamp unit functioning as a vehicle signal lamp other than a turn lamp or a headlight may be used as the lamp unit, and a cowl or bumper other than the mirror body may be used as the mounting partner of the lamp unit. In this case, the lamp unit functioning as a vehicle signal lamp or a headlight may be mounted on the front end side of the vehicle or on the rear end side of the vehicle.

[0066] In the above embodiment, the outer shape of the outer lens body 121 is a pentagonal shape (see FIG. 1) including the upper oblique side portion 12a, the lower oblique side portion 12b, the inner oblique side portion 12c, the outer oblique side portion 12d, and the connecting side portion 12e connecting the lower oblique side portion 12b and the inner oblique side portion 12c in a front view, but is not limited thereto. For example, the outer shape of the outer lens body 121 may be a polygonal shape other than a pentagonal shape (for example, a rectangular shape shown in FIG. 10), or may be a shape other than a polygonal shape (for example, an elliptical shape shown in FIG. 11). FIG. 10 shows a first modified example of the outer shape of the outer lens body 121. FIG. 11 shows a second modified example of the outer shape of the outer lens body 121.

[0067] In the above embodiment, the outer lens 12 is used as the light-transmitting cover, but the present invention is not limited to this. For example, an inner lens may be used as the light-transmitting cover.

[0068] In the above embodiment, the cutout S2 formed in the inner wall 21c (lower inner wall 21c2) of the recess 21 formed in the mirror body 20 is used as the space into which one welded portion (lower welded portion Bb) is inserted, but the present invention is not limited to this. For example, a recess, a through hole, or the like formed in the inner wall 21c (lower inner wall 21c2) of the recess 21 formed in the mirror body 20 may be used as the space into which one welded portion (lower welded portion Bb) is inserted.

[0069] In the above embodiment, an example has been described in which the bottom 111b (screw boss portion 111b1) of the housing 11 is used as the first positioning means for positioning the lamp unit 10 relative to the mounting surface (mirror body 20) with respect to the insertion direction of the lamp unit 10, but the present invention is not limited to this. For example, a positioning rib (not shown) provided on one of the bottom 111b (screw boss portion 111b1) of the housing 11 and the bottom 21b of the recess 21 formed in the mirror body 20 and abutting the other may be used as the first positioning means.

[0070] In the above embodiment, the housing side flange portion F is used as a second positioning means for positioning the lamp unit 10 relative to the mounting surface (mirror body 20) in the up, down, left and right directions. 11 In the above embodiment, the positioning rib R (see FIG. 6) is provided on the inner wall 21c of the recess 21 formed in the mirror body 20, and abuts against the inner wall 21c of the recess 21 formed in the mirror body 20. However, the present invention is not limited to this. For example, the second positioning means may be a flange portion F on the housing side provided on the inner wall 21c of the recess 21 formed in the mirror body 20. 11 A positioning rib (not shown) that abuts against the rib may also be used.

[0071] In the above embodiment, the lower welded portion Bb is disposed on the vehicle rear side of the upper welded portion Ba (see FIG. 3), and the notch S2 into which the lower welded portion Bb is inserted is formed in the inner wall 21c (lower inner wall 21c2) of the recess 21 formed in the mirror body 20 (see FIG. 3), but the present invention is not limited to this.
