[0005] By the way, when the vehicle hits the front, an obstacle may contact the lamp exposed on the upper surface of the front part of the vehicle body, and a collision load from above may act on the lamp. An object of the present invention is to provide a lamp mounting structure capable of effectively absorbing collision energy when a collision load from above acts on the lamp exposed on the upper surface of the front part of the vehicle body.

[0006] The lamp mounting structure according to an aspect of the present invention includes an upper lamp and a lower lamp attached to the front part of the vehicle body. The upper lamp includes a lamp main body with a lens exposed on the upper surface of the vehicle body, and a plurality of brackets for fixing the lamp main body. The plurality of brackets includes a first bracket. The first bracket extends outward from the lamp main body in a plan view and is fixed to the lower lamp.

[0007] According to the lamp mounting structure described above, collision energy can be effectively absorbed.

[0008] Figure 1 is a perspective view showing the front of a vehicle equipped with a lamp mounting structure according to the embodiment. Figure 2 is a perspective view of the lamp mounting structure according to the embodiment, seen from the front. Figure 3 is a plan view of the lamp mounting structure according to the embodiment. Figure 4 is a side view of the lamp mounting structure according to the embodiment. Figure 5 is a plan view of the lamp mounting structure according to the embodiment, showing the upper lamp removed. Figure 6 is a perspective view of the upper lamp of the lamp mounting structure according to the embodiment, seen from above. Figure 7 is a perspective view of the upper lamp of the lamp mounting structure according to the embodiment, seen from the front and below. Figure 8 is a perspective view of the lamp mounting structure according to the embodiment, seen from the rear, showing the upper lamp removed.

[0009] The lamp mounting structure S according to the embodiment will be described below with reference to the drawings. Elements having substantially the same function are denoted by the same reference numerals, and redundant explanations are omitted. In the drawings, FR and RR indicate the front and rear of the vehicle in the longitudinal direction, respectively. Similarly, LH and RH indicate the left and right sides in the vehicle width direction, and UP and DN indicate the top and bottom of the vehicle in the vertical direction, respectively.

[0010] As shown in Figure 1, the lamp mounting structure S is provided on the left and right sides of the front of the vehicle. Each lamp mounting structure S comprises an upper lamp 1 and a lower lamp 2. As shown in Figures 2 to 4, the upper lamp 1 is located above the lower lamp 2. In the illustrated example, the upper lamp 1 is a combination lamp in which a turn signal lamp and a positioning lamp are integrated. The upper lamp 1 is positioned between the resin bumper fascia 3, which is an outer panel of the vehicle body, and the metal or fiber-reinforced resin bonnet 4, which is also an outer panel of the vehicle body. The outer end 10X of the upper lamp 1 in the vehicle width direction reaches the front end of the front fender panel 5, which is an outer panel of the vehicle body.

[0011] In the illustrated example, the lower lamp 2 is a headlamp that incorporates both a low-beam lamp and a high-beam lamp, and is installed embedded in the bumper fascia 3. Therefore, the bumper fascia 3, which is the outer panel of the vehicle body, is located between the upper lamp 1 and the lower lamp 2.

[0012] As shown in Figures 3 to 5, a center lamp 6 is positioned adjacent to the left and right upper lamps 1, between them. In the illustrated example, the center lamp 6 is a lamp that does not have functions essential for vehicle operation, such as road lighting or direction indication. The center lamp 6 may be a garnish or plated molding that does not have a light source. The outer end of the lamp body 60 of the center lamp 6 in the vehicle width direction is positioned in contact with the inner end 10Y in the vehicle width direction of the lamp body 10 of the upper lamp 1. A mounting bracket 61 for attaching the center lamp 6 to the vehicle body is provided at the outer end of the lamp body 60 in the vehicle width direction.

[0013] The lamp mounting structure S on the left side of the vehicle will be described below. The lamp mounting structure S on the right side of the vehicle is symmetrical to the lamp mounting structure S on the left side of the vehicle, so its description will be omitted. As shown in Figures 2 to 4 and Figures 6 to 7, the upper lamp 1 comprises a lamp body 10 and three brackets that fix the lamp body 10, namely an outer bracket B11, an inner bracket B12, and an intermediate bracket B13.

[0014] As shown in Figure 3, the lamp body 10 has an elongated shape in a direction intersecting the vehicle's longitudinal direction. In the illustrated example, the lamp body 10 extends outward and upward in the vehicle width direction as it approaches the rear of the vehicle. In other words, the longitudinal direction of the lamp body 10 follows a line that extends outward and upward in the vehicle width direction as it approaches the rear of the vehicle, and the lamp body 10 has its maximum dimensions along this longitudinal direction. The lens of the lamp body 10 is exposed on the upper surface of the vehicle body and is positioned to be visible in a plan view of the vehicle.

[0015] As shown in Figures 2 to 4, the outer bracket B11 extends from the outer end 10X of the lamp body 10 toward the rear of the vehicle. The outer bracket B11 has a flat plate portion B11a at its rear end. The flat plate portion B11a extends horizontally and is bolted to the hood ridge member 7, which is the vehicle body, via a mounting bracket 70 and a plate 71 provided on the upper surface of the hood ridge member 7.

[0016] As shown in Figures 2 and 3, the inner bracket B12 is located further inward in the vehicle width direction and further forward than the outer bracket B11, and extends inward in the vehicle width direction and further rearward from the intermediate portion 10Z of the lamp body 10. The intermediate portion 10Z is the portion of the lamp body 10 between the inner end 10Y in the vehicle width direction and the base end of the intermediate bracket B13. In the illustrated example, the base end of the inner bracket B12 is positioned at a distance from the inner end 10Y of the lamp body 10 in the longitudinal direction of the lamp body 10. This makes it possible to position the mounting bracket 61 of the center lamp 6, which is positioned adjacent to the upper lamp 1, at the outer end of the center lamp 6 in the vehicle width direction, and to firmly fix that end to the upper surface of the radiator upper support member 8. The inner bracket B12 has a flat plate portion B12a at its rear end. The flat plate portion B12a extends horizontally and is bolted to the radiator upper support member 8, which is part of the vehicle body, via a mounting bracket 80 (see Figure 5) provided on the front surface of the radiator upper support member 8.

[0017] As shown in Figures 2 and 3, the intermediate bracket B13 is located further forward than the outer bracket B11 and further outward in the vehicle width direction than the inner bracket B12, extending outward from the lamp body 10 in a plan view and fixed to the lower lamp 2. Specifically, the intermediate bracket B13 extends diagonally forward from the front portion of the lamp body 10 and is fixed to the lower lamp 2. Here, "front of the lamp" means outward in the vehicle width direction and in front of the vehicle. In the illustrated example, the front portion of the lamp body 10 is the edge of the lamp body 10 that is outward in the vehicle width direction and in front of the vehicle, and is the edge of the lamp body 10 on the bumper fascia 3 side.

[0018] The fixing point of the intermediate bracket B13 to the lower lamp 2 is called the first fixing point P1, the fixing point of the outer bracket B11 to the hood ridge member 7 is called the second fixing point P2, and the fixing point of the inner bracket B12 to the radiator upper support member 8 is called the third fixing point P3. As shown in Figure 3, the third fixing point P3 is located further forward and inward in the vehicle width direction than the second fixing point P2, and the first fixing point is located further forward than the second fixing point and outward in the vehicle width direction than the third fixing point. The first fixing point P1, the second fixing point P2, and the third fixing point P3 form a triangle in plan view.

[0019] Furthermore, as shown in Figure 7, a control board 15 for controlling the upper lamp 1 is housed inside the lamp body 10. The control board 15 is positioned between the outer end 10X of the lamp body 10 and the base end of the intermediate bracket B13. The lamp body 10 has a downwardly bulging board housing section 16 that houses this control board 15. The lowest end of the board housing section 16 is located above the first fixed point P1 of the intermediate bracket B13 by a vertical distance D3 (see Figure 4). The distance D3 is greater than the vertical distance D4 (see Figure 4) from the base end of the intermediate bracket B13 to the top plate 21.

[0020] As shown in Figures 4 and 5, the lower lamp 2 comprises a lamp body 20 and four brackets for fixing the lamp body 20 to the vehicle body: an upper rear bracket B21, an upper front bracket B22, a lower front bracket B23, and a lower rear bracket B24. The lower lamp 2 also has an intermediate support bracket B25 on the upper surface of the lamp body 20 for supporting and fixing the intermediate bracket B13 of the upper lamp 1.

[0021] The upper rear bracket B21 extends from the center of the upper part of the housing of the lamp body 20 in the vehicle width direction toward the rear of the vehicle. The upper rear bracket B21 has a flat plate portion B21a at its rear end. The flat plate portion B21a extends horizontally and is fixed with bolts to the upper surface of the bridge member 9, which spans between the end of the radiator upper support member 8 and the front end of the hood ridge member 7. The upper surface of the bridge member 9 to which the flat plate portion B21a is fixed forms a flat horizontal plane. The base end of the upper rear bracket B21 is located in front of the upper surface of the bridge member 9.

[0022] The upper front bracket B22 is located further inward in the vehicle width direction and further forward than the upper rear bracket B21, and extends from the inner part of the upper part of the housing of the lamp body 20 in the vehicle width direction to the rear and further inward in the vehicle width direction. The upper front bracket B22 has a flat plate portion B22a at its rear end. The flat plate portion B22a extends horizontally and is fixed to the upper surface of the bridge member 9 with bolts. The upper surface of the bridge member 9 to which the flat plate portion B22a is fixed forms a flat horizontal plane. The base end of the upper front bracket B22 is located further forward than the upper surface of the bridge member 9.

[0023] As shown in Figure 4, the lower front bracket B23 is located lower and forward of the vehicle than the upper rear bracket B21 and the upper front bracket B22, and extends downward from the center in the vehicle width direction of the lower part of the housing of the lamp body 20. The lower front bracket B23 is fixed to the bumper reinforcement 11 via a mounting bracket 12 provided on the upper surface of the bumper reinforcement 11. The bumper reinforcement 11 is fixed to the front end of the side member 14 via a crash box 13. The lower front bracket B23 has a flat plate portion B23a at its lower end. The flat plate portion B23a extends vertically and is fixed with bolts to the vertical surface of the mounting bracket 12 on the vehicle front side. The vertical surface of the mounting bracket 12 to which the flat plate portion B23a is fixed constitutes a flat vertical surface.

[0024] As shown in Figure 4, the lower rear bracket B24 is located lower and rearward of the vehicle than the upper rear bracket B21 and the upper front bracket B22, and extends rearward from the outer side in the vehicle width direction of the lower part of the housing of the lamp body 20. The lower rear bracket B24 is fixed to the front end of the hood ridge member 7 via an auxiliary bracket (not shown) provided at the front end of the hood ridge member 7. The lower rear bracket B24 has a flat plate portion B24a at its lower end. The flat plate portion B24a extends vertically and is fixed with bolts to the vertical surface of the auxiliary bracket on the outer side in the vehicle width direction. The vertical surface of the auxiliary bracket to which the flat plate portion B24a is fixed constitutes a flat vertical surface.

[0025] When brackets for fixing the lamp body 20, such as the upper rear bracket B21 and the upper front bracket B22, are fixed to a horizontal surface on the vehicle body, the fixing point is called the horizontal fixing point PH. Similarly, when brackets for fixing the lamp body 20, such as the lower front bracket B23 and the lower rear bracket B24, are fixed to a vertical surface on the vehicle body, the fixing point is called the vertical fixing point PV. Note that "horizontal surface" is not limited to a strictly horizontal surface, but also includes surfaces inclined within a range of ±10° from a strictly horizontal surface. Similarly, "vertical surface" is not limited to a strictly vertical surface, but also includes surfaces inclined within a range of ±10° from a strictly vertical surface.

[0026] As shown in Figures 2, 4, and 5, let D1 be the three-dimensional distance between the first fixed point P1 and the vertical plane fixed point PV, and let D2 be the three-dimensional distance between the first fixed point P1 and the horizontal plane fixed point PH. The distance D1 between the first fixed point P1 and the vertical plane fixed point PV closest to the first fixed point is smaller than the distance D2 between the first fixed point P1 and the horizontal plane fixed point PH closest to the first fixed point P1. In the illustrated example, the horizontal plane fixed point PH closest to the first fixed point P1 is the fixed point of the upper rear bracket B21, and the vertical plane fixed point PV closest to the first fixed point is the fixed point of the lower rear bracket B24. The distance D1 from the first fixed point P1 to the fixed point of the upper rear bracket B21 is smaller than the distance D2 from the first fixed point to the fixed point of the lower rear bracket B24.

[0027] As shown in Figure 5, the intermediate support bracket B25 is located in front of the vehicle compared to the upper rear bracket B21. As shown in Figure 8, the intermediate support bracket B25 has an inverted U-shaped cross-section and comprises a top plate 21 to which the intermediate bracket B13 is fixed, and a pair of legs 22 extending downward from both side edges of the top plate 21. The vertical distance D4 (see Figure 4) from the base end of the intermediate bracket B13 to the top plate 21 is greater than the vertical length L1 (see Figure 8) of the legs 22 (D4 > L1).

[0028] (1) The lamp mounting structure S comprises an upper lamp 1 and a lower lamp 2 mounted on the front of the vehicle body. The upper lamp 1 comprises a lamp body 10 with a lens exposed on the upper surface of the vehicle body, and a plurality of brackets B11, B12 and B13 that fix the lamp body 10. The plurality of brackets B11, B12 and B13 include an intermediate bracket B13 which is a first bracket. The intermediate bracket B13 extends outward from the lamp body 10 in a plan view and is fixed to the lower lamp 2.

[0029] Because the intermediate bracket B13 extends outward from the lamp body 10 in a plan view, a wider gap space can be created below the lamp body 10 than if the entire intermediate bracket B13 were placed directly below the lamp body 10. This allows for a greater downward displacement of the lamp body 10 when an impact load from above acts on the upper lamp 1 due to contact with an obstacle. Furthermore, because the intermediate bracket B13 is fixed to the lower lamp 2, a portion of the impact load from above can be transmitted to the lower lamp 2. For this reason, the downward displacement of the lamp body 10 can be increased by the amount of deformation of the lower lamp 2, compared to, for example, if all the brackets fixing the lamp body 10 were fixed to the vehicle body, thereby increasing the amount of energy absorbed. In other words, the lamp mounting structure S can effectively absorb impact energy when an impact load from above is input to the upper lamp 1.

[0030] (2) The intermediate bracket B13 may extend from the front portion of the lamp body 10 and be fixed to the lower lamp 2, as shown in the illustrated example. In this case, the amount of downward displacement of the front portion of the lamp body 10 when an impact load from above acts on the upper lamp 1 can be made larger than that of other portions. As a result, impact energy can be absorbed more effectively when an impact load from above is applied to the front portion of the lamp body 10.

[0031] (3) The lower lamp 2 may be provided with an intermediate support bracket B25, which is a second bracket, as shown in the illustrated example. The intermediate support bracket B25 comprises a top plate 21 to which the intermediate bracket B13 is fixed, and a leg portion 22 extending downward from the top plate 21. The vertical distance D4 (see Figure 4) from the base end of the intermediate bracket B13 to the top plate 21 is greater than the vertical length L1 (see Figure 8) of the leg portion 22.

[0032] Therefore, when an impact load from above is applied to the upper lamp 1, the intermediate bracket B13 can be deformed more reliably, and the impact energy can be absorbed by this deformation. Furthermore, the load transmitted to the leg portion 22 via the intermediate bracket B13 and the top plate 21 from the impact load can deform the leg portion 22, and the impact energy can also be absorbed by this deformation of the leg portion 22. In other words, the amount of impact energy absorbed can be increased compared to when the intermediate bracket B13 is directly fixed to the outer wall of the lamp body 20 without the intermediate support bracket B25.

[0033] (4) The lower ramp 2 may include a third bracket, which is an upper rear bracket B21 and an upper front bracket B22, and a fourth bracket, which is a lower front bracket B23 and a lower rear bracket B24, as shown in the illustrated example. The upper rear bracket B21 and the upper front bracket B22 are fixed to a horizontal surface provided on the vehicle body at a horizontal plane fixing point PH. The lower front bracket B23 and the lower rear bracket B24 are fixed to a vertical surface provided on the vehicle body at a vertical plane fixing point PV. The distance D1 between the first fixing point P1, which is the fixing point of the intermediate bracket B13 to the lower ramp 2, and the horizontal plane fixing point PH closest to the first fixing point P1 is smaller than the distance D2 between the first fixing point P1 and the vertical plane fixing point PV closest to the first fixing point P1.

[0034] For loads applied in the vertical direction, the lower front bracket B23 and lower rear bracket B24 fixed to the horizontal plane fixed point PH are more easily deformed in the vertical direction than the lower front bracket B23 and lower rear bracket B24 fixed to the vertical plane fixed point PV. Therefore, when the distance D1 is less than the distance D2, the impact load applied from the intermediate bracket B13 can move the first fixed point P1 downwards more significantly than when the distance D1 is greater than or equal to the distance D2. In other words, the amount of downward displacement of the ramp body 10 and the deformation of the lower ramp 2 can be further increased, and the amount of energy absorbed can be increased even further.

[0035] In the illustrated example, as shown in Figure 5, even in a plan view, the distance between the first fixed point P1 and the horizontal fixed point PH closest to the first fixed point P1 is smaller than the distance between the first fixed point P1 and the vertical fixed point PV closest to the first fixed point P1. Therefore, the collision load input from the intermediate bracket B13 can more reliably move the first fixed point P1 downward, thereby increasing the amount of energy absorbed.

[0036] (5) As shown in the illustrated example, the outer bracket B11, which is the fifth bracket, may extend from the lamp body 10 and be fixed to the vehicle body at the second fixing point P2. The inner bracket B12, which is the sixth bracket, may extend from the lamp body 10 and be fixed to the vehicle body at the third fixing point P3. The first fixing point P1, the second fixing point P2, and the third fixing point P3 may form a triangle in plan view, as illustrated in Figure 3. This makes it possible to stably support the upper lamp 1 with a minimum number of brackets, and to obtain the effects of (1) to (3) above while reducing weight and cost.

[0037] (6) As shown in the illustrated example, the lamp body 10 of the upper lamp 1 may have a shape that is elongated in a direction intersecting the vehicle's longitudinal direction. The outer bracket B11 may extend from the outer end 10X in the vehicle width direction of the lamp body 10, and the inner bracket B12 may extend from the intermediate portion 10Z between the inner end 10Y in the vehicle width direction of the lamp body 10 and the base end of the intermediate bracket B13. The control board 15 housed inside the lamp body 10 may be positioned between the outer end 10X and the base end of the intermediate bracket B13.

[0038] By positioning the control board 15 between the outer end 10X and the base end of the intermediate bracket B13, the center of gravity of the upper lamp 1 can be positioned or brought closer to the inside of the triangle, thereby improving the support balance of the upper lamp 1. In particular, as shown in the illustrated example, when the center lamp 6 is positioned adjacent to the upper lamp 1 and the outer end of the center lamp 6 in the vehicle width direction abuts against the inner end 10Y of the lamp body 10, it may not be possible to position the inner bracket B12 at the inner end 10Y of the lamp body 10. In this case, the triangle formed by the first fixed point P1, the second fixed point P2, and the third fixed point P3 becomes smaller compared to when the inner bracket B12 extends from the inner end 10Y of the lamp body 10. By extending the inner bracket B12 from the intermediate part 10Z and positioning the control board 15 between the outer end 10X and the base end of the intermediate bracket B13, the center of gravity of the upper lamp 1 can be positioned adjacent to the center lamp 6 while being positioned or brought closer to the inside of the reduced triangle. This makes it possible to achieve both improved support balance and enhanced aesthetics.

[0039] (7) The lamp body 10 may have a downwardly bulging substrate housing section 16 for housing the control board 15. The lowest end of the substrate housing section 16 may be located above the first fixed point P1 (for example, by a vertical distance D3 above). In this case, the downward displacement stroke of the lamp body 10 can be secured, and the intermediate bracket B13 can be deformed more reliably when an impact load is applied to the lamp body 10 from above. In the illustrated example, the distance D3 is greater than the vertical distance D4 (see Figure 4) from the base end of the intermediate bracket B13 to the top plate 21 of the intermediate support bracket B25. Therefore, the downward displacement stroke of the lamp body 10 can be secured more reliably, and the intermediate bracket B13 can be deformed before the substrate housing section 16 interferes with other parts.

[0040] (8) As shown in the illustrated example, the intermediate bracket B13 may extend forward from the front portion of the lamp body 10 and be fixed to the lower lamp 2. Alternatively, the outer bracket B11 and inner bracket B12 may extend from the rear portion of the lamp body 10 (i.e., the edge on the bonnet 4 side) and be fixed to the vehicle body. In this case, the amount of downward displacement of the lamp body 10 when an impact load from above acts on the upper lamp 1 can be made greater in the portion of the lamp body 10 on the front side than in the portion of the lamp body 10 on the rear side. That is, the lamp body 10 can be rotated while suppressing the downward displacement of the portion of the lamp body on the rear side, or in other words, the lamp body 10 can be tilted forward. As a result, interference between the circuit board housing 16 and other components can be prevented, and the control board 15 can be protected.

The technical scope of the invention is not limited to the specific technical matters disclosed in the embodiments above, but also includes various modifications, changes, and alternative technologies that can be easily derived therefrom.

However, the types of the upper lamp and the lower lamp are not particularly limited. Further, in the above-described embodiment, an example in which the upper lamp 1 is a combination lamp and the lower lamp 2 is a headlamp has been shown.
