[0027] In addition, the drawings are schematic views showing the resin member for vehicle according to the present application, and thus, detailed portions of the resin member for vehicle according to the present application are omitted in the drawings. In addition, hatching is omitted in the cross-sectional explanatory views.

[0028] (Explanation of the structure of Example 1)

[0029] Figures 1 to 5 Example 1 of the resin member for vehicle according to the present application is shown. Hereinafter, the structure of the resin member for vehicle according to the present embodiment 1 will be described. In the drawings, the symbol 1C is the resin member for vehicle according to the present embodiment 1 (hereinafter, simply referred to as "resin member for vehicle").

[0030] (Explanation of the center-side rear combination lamp (resin member for vehicle) 1C)

[0031] As shown in Figure 1 , in this example, the resin member for vehicle 1C is a vehicle lamp, and is a center-side rear combination lamp. Hereinafter, the resin member for vehicle 1C will be referred to as the center-side rear combination lamp 1C.

[0032] The center-side rear combination lamp 1C is equipped at a central portion of the rear portion of the vehicle V, and in this example, at the movable-side rear door. The resin member for vehicle 1C is equipped over a large portion of the entire width direction (left-right direction) of the vehicle V.

[0033] At both side portions of the rear portion of the vehicle V, and in this example, at the fixed-side vehicle body, a vehicle lamp, that is, a left-side rear combination lamp 1L, and similarly, a vehicle lamp, that is, a right-side rear combination lamp 1R, are respectively equipped.

[0034] The center-side rear combination lamp 1C, the left-side rear combination lamp 1L, and the right-side rear combination lamp 1R constitute a vehicle lamp, that is, a rear combination lamp, having a sense of unity (a sense of connection) over the entire width direction (left-right direction) of the vehicle V.

[0035] As shown in Figure 1 , Figure 2 ,Figure 3 (A) and Figure 4 As shown in (A), the center-side rear combination lamp 1C is provided with a lamp lens 2 as a first resin member and a lamp housing 3 as a second resin member.

[0036] The lamp lens 2 and the lamp housing 3 are fixed to each other by fusion pressure bonding (i.e., hot plate fusion bonding). The lamp lens 2 and the lamp housing 3 form a lamp chamber 4.

[0037] Inside the lamp chamber 4, a lamp unit, optical members (inner lens, etc.), decorative members (inner housing, inner plate, etc.), and mounting members (bracket, etc.) are arranged, which are not shown.

[0038] The lamp unit has a light source (not shown). As the lamp unit, for example, a tail lamp, a stop lamp, a turn signal lamp, a backup lamp, etc. are exemplified.

[0039] (Explanation of the lamp lens 2)

[0040] In this example, the lamp lens 2 is composed of a light-transmissive resin (e.g., acrylic, etc.). The lamp lens 2 has a main body portion 20, a foot portion 21, and a fusion portion 22.

[0041] The plate thickness (wall thickness) of the main body portion 20 is, in this example, a plate shape of about 1.0 mm to about 3.0 mm. In addition, the main body portion 20 is a rectangular shape in which the front view shape (the shape of the front side as viewed from the rear side of the vehicle V) is longer in the lateral direction (left-right direction). In addition, the plate thickness (wall thickness) of the main body portion 20 needs to be, in this example, about 1.0 mm at the minimum, in terms of the relative relationship with the diameter of the ejection pin.

[0042] The foot portion 21 is integrally provided from the entire peripheral portion of the main body portion 20 to the lamp housing 3 side (from the rear side of the vehicle V to the front side) so as to be inclined (bent) thereto. That is, the foot portion 21 is provided on the main body portion 20 so as to be inclined at an angle θ1 with respect to the direction P of the fusion pressure bonding. In this example, the angle θ1 is about 45° to about 60°.

[0043] In addition, as shown in (A), the foot portion 21 is inclined with respect to the front view direction so as to overlap the lamp lens 2L of the left-side rear combination lamp 1L, which is adjacently equipped on the vehicle V, in the front view direction (the front-rear direction of the vehicle V). Note that the front view direction is substantially in the same direction as, i.e., substantially parallel to, the direction P of the fusion pressure bonding. Figure 3 The fusion portion 22 is integrally provided from the front end (the end portion on the opposite side with respect to the end portion of the main body portion 20) of the foot portion 21 so as to be bent in the direction opposite to the bending direction of the foot portion 21. That is, the fusion portion 22 is provided on the foot portion 21 so as to be inclined at an angle θ2 with respect to the inclination direction of the foot portion 21 toward the side opposite to the main body portion 20. In this example, the angle θ2 is from about 20° to the above-described angle θ1.

[0044] In addition, as shown in (A), the foot portion 21 is inclined with respect to the front view direction so as to overlap the lamp lens 2L of the left-side rear combination lamp 1L, which is adjacently equipped on the vehicle V, in the front view direction (the front-rear direction of the vehicle V). Note that the front view direction is substantially in the same direction as, i.e., substantially parallel to, the direction P of the fusion pressure bonding.

[0045] In this example, the length Tl of the foot portion 21 and the fusion portion 22 is about 10 mm or more. The length Tl of the foot portion 21 and the fusion portion 22 is the length in the direction of the inclination of the foot portion 21 from the main body portion 20 to the lamp housing 3.

[0046] In this example, the length T2 of the fusion portion 22 is about 1.0 mm or more. The length T2 of the fusion portion 22 is the length in the direction of the center line of the fusion portion 22 from the bent corner portion of the foot portion 21 to the lamp housing 3.

[0047] (Explanation of the lamp housing 3)

[0048] In this example, the lamp housing 3 is composed of a light non-transmissive resin (ABS resin or the like). The lamp housing 3 has a main body portion 30, a fusion portion 31, and a convex portion 32.

[0049] The main body portion 30 is in the same manner as the main body portion 20 of the lamp lens 2 in a plate shape, and the front view shape is in a long rectangular shape which is longer in the lateral direction.

[0050] The fusion portion 31 is the front surface (the surface opposite to the lamp lens 2) of the main body portion 30, and is integrally provided at a position slightly toward the center side than the entire peripheral portion of the main body portion 30. The front surface of the fusion portion 31 and the front surface of the main body portion 30 are in the same plane.

[0051] The convex portion 32 is integrally projected from the entire peripheral portion of the main body portion 30 toward the lamp lens 2 side (from the front side of the vehicle V toward the rear side).

[0052] (Explanation of the fusion process of the lamp lens 2 and the lamp housing 3)

[0053] First, the lamp lens 2 and the lamp housing 3 are respectively received and held in a jig by a chuck or the like (not shown).

[0054] Next, the fusion portion 22 of the lamp lens 2 and the fusion portion 31 of the lamp housing 3 are respectively softened by a hot plate (heating block) not shown. In addition, the fusion portion 22 of the lamp lens 2 and the fusion portion 31 of the lamp housing 3 can be in either of a contact state or a non-contact state with the heating block.

[0055] Then, the fusion portion 22 of the lamp lens 2 is pressed to the fusion portion 31 of the lamp housing 3 in the direction P of the solid arrow in Fig. 6 by the jig. The pressing direction P is a perpendicular direction with respect to the main body portion 20 of the lamp lens 2 and the main body portion 30 of the lamp housing 3. Figure 2

[0056] Thus, the fusion portion 22 of the lamp lens 2 and the fusion portion 31 of the lamp housing 3 are fused to each other. Thereby, the lamp lens 2 and the lamp housing 3 are integrally fixed, and in addition, the lamp chamber 4 is formed.

[0057] ​At this time, the amount of fusion of the fusion portion 22 is largest at about 0.5 mm in this example. Thus, the length T2 of the fusion portion 22 before fusion is about 1.0 mm or more in this example, and thus the length of the fusion portion 22 after fusion is about 0.5 mm in this example. As a result, the fusion portion 22 is always present at the time of the fusion process, and rigidity and pressing force can be ensured with respect to the pressing direction P.

[0058] As above, the rear combination lamp 1C on the center side, which is the resin member for vehicle 1C according to the present embodiment 1, is constituted.

[0059] (Explanation of the rear combination lamp 1L on the left side)

[0060] Hereinafter, the rear combination lamp 1L on the left side will be explained. The lamp lens 2L of the rear combination lamp 1L on the left side is provided with the lamp lens 2L and the lamp case 3L, similarly to the rear combination lamp 1C on the center side described above.

[0061] The lamp lens 2L and the lamp case 3L are fixed to each other by fusion pressing (i.e., hot plate fusion). The lamp lens 2L and the lamp case 3L form the lamp chamber 4L.

[0062] Inside the lamp chamber 4L, a lamp unit, optical members (inner lens, etc.), decorative members (inner case, inner plate, etc.), mounting members (bracket, etc.), not shown, are arranged. The lamp unit has a light source (not shown). As the lamp unit, for example, a tail lamp, a stop lamp, a turn signal lamp, a backup lamp, etc., are exemplified.

[0063] In this example, the lamp lens 2L is constituted by a light-transmissive resin (e.g., acrylic, etc.). The lamp lens 2L has a main body portion 20L, a foot portion 21L, and a fusion portion 22L.

[0064] The portion of the foot portion 21L opposite to the rear combination lamp 1C on the center side described above is provided obliquely to the opposite side of the main body portion 20L from the edge portion of the main body portion 20L to the side of the lamp case 3L.

[0065] Thus, the rear combination lamp 1L on the left side and the rear combination lamp 1C on the center side described above are equipped adjacently on the vehicle V. Then, as shown in (A), the foot portion 21L of the lamp lens 2L of the rear combination lamp 1L on the left side overlaps the foot portion 21 of the lamp lens 2 of the rear combination lamp 1 on the center side in the front view direction. Figure 3

[0066] In addition, the structure of the rear combination lamp 1R on the right side is left-right symmetrical to the structure of the rear combination lamp 1L on the left side. Thus, the explanation of the structure of the rear combination lamp 1R on the right side is omitted.

[0067] (Explanation of the effect of the present embodiment 1)

[0068] The rear combination lamp 1C on the center side according to the present embodiment 1 is constituted by the structure as described above, and the effect thereof will be explained below.​

[0069] The light source of the lamp unit of the rear combination lamp 1C, 1L, 1R is lit. Then, light is emitted from the light source. Most of the light from the light source is emitted to the outside through the main body portion 20, 20L of the lamp lens 2, 2L.

[0070] In addition, a part of the light from the light source is emitted to the outside through the foot portion 21, 21L of the lamp lens 2, 2L. Thus, the rear combination lamp 1C on the center side (movable side of the rear door), the rear combination lamp 1L on the left side (fixed side of the vehicle body), and the rear combination lamp 1R on the right side (fixed side of the vehicle body) look integrally illuminated in the entire width direction (left-right direction) of the vehicle V. That is, the rear combination lamps 1C, 1L, 1R have an integrated feeling (a connected feeling).

[0071] (Explanation of Effects of Embodiment 1)

[0072] The rear combination lamp 1C on the center side according to the present embodiment 1 has the structure and the effects as described above, and the effects thereof will be described below.

[0073] The rear combination lamp 1C on the center side according to the present embodiment 1 is such that, in the lamp lens 2 as the first resin member, the inclined direction of the fusion portion 22 with respect to the foot portion 21 is bent in the opposite direction on the foot portion 21. Thus, the rear combination lamp 1C on the center side according to the present embodiment 1 can secure rigidity and pressure force of the fusion portion 22 with respect to the pressure direction P even if the foot portion 21 is inclined at an angle θ1 with respect to the pressure direction P when the lamp lens 2 is fusion pressure-bonded to the lamp case 3.

[0074] As a result, the rear combination lamp 1C on the center side according to the present embodiment 1 can fusion pressure-bond the lamp lens 2 to the lamp case 3 via the fusion portion 22 even if the foot portion 21 of the lamp lens 2 is inclined with respect to the main body portion 20. In this way, the rear combination lamp 1C on the center side according to the present embodiment 1 can secure the required fusion strength even if the shape of the main body portion 20 of the lamp lens 2 is formed in a desired appearance shape.

[0075] Hereinafter, the rear combination lamp 1 on the center side according to the present embodiment 1 will be described with reference to Figure 3 (B) A rear combination lamp (resin member for a vehicle, a lamp device for a vehicle) 1 on the center side not according to the present embodiment will be described. In Figure 3 (B) is the same as Figure 1 , Figure 2 , Figure 3 (A) and Figure 4 The same symbols as in (A) and (B) denote the same members.

[0076] The central-side rear combination lamp 1 directly welds the leg portion 21 to the weld portion 31 of the lamp housing 3 via the weld portion 22. As a result, the central-side rear combination lamp 1 is unable to secure rigidity and pressure in the pressure direction P along the inclination direction of the leg portion 21 when the lamp lens 2 is welded and pressed to the lamp housing 3. The greater the inclination angle θ1 of the leg portion 21, the more difficult it is to secure rigidity and pressure.

[0077] As a result, the central-side rear combination lamp 1 according to the present embodiment 1 is able to secure the required welding strength even when the shape of the main body portion 20 of the lamp lens 2 is formed into the desired appearance shape.

[0078] In addition, in the central-side rear combination lamp 1, if the plate thickness (wall thickness) of the lamp lens 2 is thickened to about 3.0 mm or more, the required welding strength can sometimes be secured. In this case, since the plate thickness (wall thickness) of the lamp lens 2 is thickened, the weight and cost increase, and in addition, become a main cause of the generation of sink marks and the like.

[0079] In contrast, the central-side rear combination lamp 1C according to the present embodiment 1 welds the leg portion 21 to the weld portion 31 of the lamp housing 3 via the weld portion 22. As a result, the central-side rear combination lamp 1 according to the present embodiment 1 is able to secure the required welding strength even when the shape of the main body portion 20 of the lamp lens 2 is formed into the desired appearance shape.

[0080] Furthermore, the central-side rear combination lamp 1C according to the present embodiment 1 does not need to thicken the plate thickness (wall thickness) of the lamp lens 2 to about 3.0 mm or more, and in this example, can be thinned to about 1.0 mm to about 3.0 mm. As a result, the central-side rear combination lamp 1C according to the present embodiment 1 is able to reduce the weight and cost of the central-side rear combination lamp 1C in accordance with the amount by which the plate thickness (wall thickness) of the lamp lens 2 is thinned, and is able to prevent the generation of sink marks and the like.

[0081] In addition, in the central-side rear combination lamp 1C according to the present embodiment 1, the leg portion 21 of the lamp lens 2 is inclined with respect to the front view direction in a manner that overlaps the leg portion 21L of the lamp lens 2L of the left-side rear combination lamp 1L and the right-side rear combination lamp 1R equipped adjacently on the vehicle V in the front view direction. As a result, a portion of the light from the light source of the central-side rear combination lamp 1C according to the present embodiment 1 is emitted to the outside through the leg portions 21, 21L of the lamp lenses 2, 2L.

[0082] As a result, the central-side rear combination lamp 1C according to the present embodiment 1 emits light in unison with the left-side rear combination lamp 1L and the right-side rear combination lamp 1R over the entire width direction (left-right direction) of the vehicle V. That is, the rear combination lamps 1C, 1L, 1R have a sense of unity (connection).

[0083] (Explanation of the foot portion 23 of the modification example)

[0084] Hereinafter, the structure, action, and effects of the vehicle resin member 1C according to the embodiment 1 will be explained with reference to the drawings. Figure 5 The foot portion 23 of the modification example will be explained. The length T3 of the foot portion 23 is longer than the length T1 of the foot portion 21 explained above, and is about 30 mm or more in this example.

[0085] In addition, the inclination angle Θ3 of the foot portion 23 is about 15° or more in this example. Also, the angle Θ4 formed by the foot portion 23 and the fusing portion 22 is about 10° to the angle Θ3 explained above in this example.

[0086] The same action effects as the foot portion 21 explained above can be achieved even in the case of the foot portion 23 of the modification example. In particular, the length T3 of the foot portion 23 of the modification example is longer than the length T1 of the foot portion 21 explained above. Therefore, the amount of overlap of the foot portion 23 of the modification example with the main visual direction of the foot portion 21L of the lamp lens 2L of the adjacent rear combination lamp 1L, 1R is longer (larger). Accordingly, the integrated feeling (connection feeling) of the central rear combination lamp 1C with the left and right rear combination lamps 1L, 1R is improved.

[0087] (Explanation of the structure, action, and effects of the embodiment 2)

[0088] Figures 6 to 8 An embodiment 2 of the vehicle resin member according to the present application will be explained. Hereinafter, the structure, action, and effects of the vehicle resin member 100L according to the embodiment 2 will be explained. In the drawings, the same symbols as those of the vehicle resin member 1C according to the embodiment 1 explained above denote the same components. Figures 1 to 5

[0089] The vehicle resin member 1C according to the embodiment 1 explained above is the central rear combination lamp 1C. The vehicle resin member 100L according to the embodiment 2 is the left rear combination lamp 100L (the right rear combination lamp 100R).

[0090] The central rear combination lamp 100C is equipped at the center of the rear portion of the vehicle V. The left rear combination lamp 100L and the right rear combination lamp 100R are respectively equipped at the left and right sides of the rear portion of the vehicle V and at the left and right sides of the central rear combination lamp 100C.

[0091] Hereinafter, the left rear combination lamp 100L will be explained. In addition, the structure of the right rear combination lamp 100R is left-right symmetrical to that of the left rear combination lamp 100L. Therefore, the explanation of the structure of the right rear combination lamp 100R will be omitted.

[0092] The left rear combination lamp 100L is provided with the lamp lens 200 and the lamp housing 300. The lamp lens 200 and the lamp housing 300 are fixed to each other by fusing and pressing (i.e., hot plate fusing). The lamp lens 200 and the lamp housing 300 form the lamp chamber 4.​

[0093] In the lamp chamber 4, a lamp unit not shown, optical members (inner lens, etc.), decorative members (inner case, inner plate, etc.), mounting members (bracket, etc.) are arranged. The lamp unit has a light source (not shown). As the lamp unit, for example, a tail lamp, a stop lamp, a turn signal lamp, a back lamp, etc. are exemplified.

[0094] The lamp lens 200 is composed of a light-transmissive resin (for example, acrylic, etc.). The lamp lens 200 has a main body portion 201, a foot portion 210, a fusion portion 222, and a wrap-around portion 202.

[0095] The portion of the foot portion 210 that opposes the rear combination lamp 100C on the center side is disposed on the main body portion 201 side obliquely from the edge portion of the main body portion 201 toward the lamp case 3 side.

[0096] The lamp case 300 is composed of a light-non-transmissive resin (ABS resin, etc.). The lamp case 300 has a main body portion 301, a fusion portion 310, and a wrap-around portion 302.

[0097] The main body portion 201 and the main body portion 301 are arranged on the inner side of the vehicle V. On the other hand, the wrap-around portion 202 and the wrap-around portion 302 are arranged on the outer side of the vehicle V and on both sides of the vehicle V. That is, the main body portion 201 and the main body portion 301 have the wrap-around portion 202 and the wrap-around portion 302 that wrap around toward the foot portion 210 side of the lamp lens 200.

[0098] The portion of the foot portion 210 of the lamp lens 200 that opposes the rear combination lamp 100C on the center side is disposed on the main body portion 201 side obliquely from the edge portion of the main body portion 201 toward the lamp case 300 side.

[0099] The fusion portion 220 of the lamp lens 200 is integrally disposed by bending from the front end of the foot portion 210 in a direction opposite to the bending direction of the foot portion 210.

[0100] The fusion portion 220 of the lamp lens 200 and the fusion portion 310 of the lamp case 300 are fixed to each other by fusion pressure. Thereby, the lamp chamber 4 is formed.

[0101] The vehicle resin member 100L according to the present embodiment 2 is composed of the structure as described above, and thus can achieve the same effect as the vehicle resin member 1C according to the present embodiment 1 described above.

[0102] In particular, the vehicle resin member 100L according to the present embodiment 2 can ensure the required fusion strength even in a case where the wrap-around portions 202 and 302 are large and the lengths of the wrap-around portions 202 and 302 in the front-rear direction of the vehicle V are long.

[0103] That is, if the lengths of the wrap-around portions 202 and 302 in the front-rear direction of the vehicle V are long, the pressure direction P is inclined from the direction perpendicular to the surface of the main body portion 201. Figure 7The upward and downward directions in the above embodiment 1 are inclined to the leftward and rightward directions. Thus, the inclination angle of the foot portion 210 with respect to the pressing direction P becomes large.

[0104] However, the resin member for vehicle 100L according to the present embodiment 2 is provided with the fusion portion 220 at the front end of the foot portion 210, and thus even if the inclination angle of the foot portion 210 with respect to the pressing direction P becomes large, the required fusion strength can be ensured.

[0105] (Explanation of Examples Other Than Embodiments 1 and 2)

[0106] In addition, in the above-described embodiments 1 and 2, as the resin member for vehicle 1C, 100L, examples in which the resin member for vehicle 1C, 100L is used in the rear combination lamp 1C on the center side and the rear combination lamp 100L (the rear combination lamp 100R) on the left side are explained. However, in the present application, as the resin member for vehicle, it can also be used in a vehicle lamp other than the rear combination lamp, or a vehicle member other than the vehicle lamp, such as an optical member (inner lens, etc.), a decorative member (inner case, inner plate, etc.).

[0107] In addition, in the above-described embodiments 1 and 2, the fusion portion 22, 220 is in a linear shape. However, in the present application, as long as the fusion portion 22, 220 can ensure rigidity and pressing force with respect to the pressing direction P, the fusion portion 22, 220 can also be in a shape other than a linear shape, such as a curved shape.

[0108] In addition, in the above-described embodiments 1 and 2, the length T2 of the fusion portion 22, 220 before fusion is about 1.0 mm or more. However, in the present application, the length T2 of the fusion portion 22, 220 before fusion can also be about 0.5 mm or more. That is, since the fusion amount of the fusion portion 22, 220 is about 0.5 mm, after fusion, there is also a fusion portion 22, 220 as long as it can ensure rigidity and pressing force with respect to the pressing direction P.

[0109] In addition, the present application is not limited to the above-described embodiment 1.
