Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a vehicle lamp mounting structure.
[0002]
[Prior art]
As a vehicle body front end component member disposed in front of the engine room, for example, there is a front end panel integrally formed of a reinforced resin to which fiber fibers are added. Openings are formed in the front end panel on both left and right sides in the front-rear direction, and headlamps are mounted in the openings.
[0003]
The headlamp is mounted with a predetermined clearance (gap) between the headlamp and the inner surface of the opening through a bracket that can be easily broken by an impact so that the headlamp can move backward and absorb the impact at the time of a vehicle frontal collision ( For example, see Patent Document 1.)
[0004]

JP 2001-233121 A
[Problems to be solved by the invention]
However, in such a conventional structure, a predetermined clearance is provided between the headlamp and the inner surface of the opening to reliably move the headlamp backward at the time of a vehicle collision. The relatively high-temperature air warmed in the room goes around the front side of the vehicle body and returns to the radiator again, which may reduce the cooling efficiency of the radiator (blow-back phenomenon). In particular, when the vehicle is idling with the vehicle stopped, running air due to the ram pressure is not supplied to the radiator, so that the cooling efficiency is significantly reduced.
[0006]
The present invention has been made by paying attention to such a conventional technique, and an object of the present invention is to provide a mounting structure for a vehicle lamp in which a blow-back phenomenon does not occur even if a clearance is secured.
[0007]
[Means for Solving the Problems]
According to the first aspect of the present invention, a vehicle is provided in which openings are formed on both left and right sides of a vehicle body front end component member disposed in front of an engine room, and a lamp is mounted in a state where clearance is secured in the openings. A rear part of the opening is closed by a case part which is more easily deformed than a vehicle front end component member.
[0008]
The invention according to claim 2 is characterized in that the case portion has a shape substantially corresponding to the outer shape of the lamp rear portion.
[0009]
The invention according to claim 3 is characterized in that the case portion is formed of a synthetic resin.
[0010]
The invention according to claim 4 is characterized in that the vehicle body front end component is a synthetic resin molded product, and the thin resin container-shaped case is integrally formed with the vehicle body front end component.
[0011]
The invention according to claim 5 is characterized in that a valve replacement hole is formed in a rear surface of the case portion, and the valve replacement hole is closed by a removable cap.
[0012]
【The invention's effect】
According to the first aspect of the invention, since the rear of the opening is closed by the case, the engine hot air does not pass through the clearance, and the blow-back phenomenon does not occur. In addition, since the case itself is easily deformed, the function of the lamp moving backward in the event of a vehicle collision and absorbing the impact is not hindered.
[0013]
According to the second aspect of the present invention, since the case portion has a shape substantially corresponding to the rear portion of the lamp, the space occupied by the case portion behind the opening is small, and it is difficult to press the installation space of other equipment. Absent.
[0014]
According to the third aspect of the present invention, since the case portion is made of synthetic resin, the case portion can be easily formed into a shape substantially corresponding to the rear portion of the lamp.
[0015]
According to the fourth aspect of the present invention, since the synthetic resin case is integrally formed with the synthetic resin body front end component, the case is formed separately from the body front end component. Work is not required, and the case portion can be easily formed.
[0016]
According to the invention as set forth in claim 5, even when the rear of the opening is closed by the case, the bulb replacement hole with the cap is formed in the case, so that the lamp is mounted in the opening by removing the cap. The replacement of the valve can be performed as it is.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
[0018]
FIG. 1 shows a front end panel 1 as a “vehicle front end component member” disposed in front of an engine room E. The illustrated portion is a left portion in the vehicle traveling direction. The front end panel 1 is integrally formed of a synthetic resin to which fiber fibers are added.
[0019]
A radiator core support upper 2 extending in the vehicle width direction is formed above the front end panel 1. The radiator core support upper 2 has a U-shaped cross section opened rearward, and pillars 3 (only the left side is shown) extending vertically are formed on both left and right sides. The lower end of the pillar 3 is connected to a radiator core support lower (not shown). A radiator 4 for circulating and cooling engine cooling water is provided between the left and right pillars 3.
[0020]
A portion of the radiator core support upper 2 extending outward in the vehicle width direction from the pillar 3 is slightly inclined backward, and both end portions 2a thereof are connected to a hood ridge (not shown).
[0021]
Below the radiator core support upper 2, a substantially L-shaped radiator core support side 5 extending from the middle of the pillar 3 to both ends 2 a of the radiator core support upper 2 is formed. The radiator core support side 5 also basically has a substantially U-shaped cross section with a rear opening. The radiator core support side 5, the radiator core support upper 2, and the upper portion of the pillar 3 form an opening 7 for mounting a headlamp 6.
[0022]
The headlamp 6 has a horizontally long shape in which three bulbs 8 are housed, and a cylindrical holder 9 corresponding to each bulb 8 is formed behind the headlamp 6. Further, two brackets 10 are formed on the upper surface of the headlamp 6 and one bracket 10 is formed on the lower surface, and these brackets 10 are attached to the fastening portions 11 recessed at the corresponding positions of the radial core support upper 2 and the radiator core support side 5. The headlamp 6 is attached to the inside of the opening 7 by being attached by means of bolts and nuts (not shown).
[0023]
A predetermined clearance C is secured between the headlamp 6 and the inner surface of the opening 7, and when the impact F at the time of a vehicle collision is applied to the headlamp 6 and the headlamp 6 breaks the bracket 10, the opening The environment is such that the inside of the vehicle 7 can be moved backward. A small hole 13 for taking out the harness 12 of the headlamp 6 to the outside is formed on the upper surface of the radiator core support side 5 forming the lower surface of the opening 7.
[0024]
A case portion 14 (see the hatched portion in FIG. 1) that covers the rear portion of the headlamp 6 and closes the opening 7 is integrally formed from the rear peripheral portion of the opening 7. That is, the case portion 14 is continuously formed from the upper portions of the radiator core support upper 2, the radiator core support side 5, and the pillar 3 which form the opening portion 7 in a state where the thickness is reduced, and has a thin resin container shape as a whole. Is presented. Since the thickness of the case portion 14 is small, the strength is lower than that of the radiator core support upper 2 or the like.
[0025]
A concave portion 15 corresponding to the holder 9 is formed on the rear surface of the case portion 14, and the case portion 14 has a shape corresponding to the rear portion of the headlamp 6 as a whole. That is, there is no useless space between the case 14 and the headlamp 6, and the space occupied by the case 14 is minimized. Therefore, by forming the case portion 14, the installation space for other devices behind the opening 7 is not pressed.
[0026]
Since the case portion 14 is made of a synthetic resin, it is possible to easily take a corresponding shape even for the headlamp 6 having a complicated shape. Furthermore, since the case portion 14 is integrally formed with the radiator core support upper 2 and the like from the beginning, the mounting work as in the case where the case portion 14 is separated is not required, and the formation of the case portion 14 is easy.
[0027]
A valve replacement hole 16 is formed at the bottom of the recess 15 in the case portion 14. The bulb replacement hole 16 is closed by a removable rubber cap 17. By removing the cap 17, the headlamp 6 is kept in the opening 2 and the bulb 8 is removed. Exchange can take place.
[0028]
According to this embodiment, since the rear of the opening 7 is closed by the case portion 14, the hot air from the engine room E does not pass through the clearance C and is blown back to the front of the vehicle. Therefore, the hot air does not flow back to the radiator 4 again, and the cooling efficiency of the radiator 4 is not reduced.
[0029]
In addition, since the case portion 14 is thin and easily deformed, the case portion 14 is not obstructed by the rearward movement of the headlamp 6 when the headlamp 6 breaks the bracket 10 and moves rearward due to the impact F at the time of a vehicle collision. The shock absorbing effect by the backward movement of the headlamp 6 can be reliably obtained. In particular, when the thin case portion 14 is formed integrally with the radiator core support upper 2 and the like formed of a synthetic resin reinforced by the addition of fibers, the rearward movement of the headlamp 6 at the time of collision while securing the required rigidity as a whole. Is beneficial.
[0030]
In the above embodiment, an example is shown in which the synthetic resin-integrated case portion 14 is formed on the resin front end panel 1 as the “vehicle front end component member”. However, a metal radiator core support structure is provided. Alternatively, a separate case portion made of resin may be attached.
