DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle headlamp mounting structure.

[0002]

2. Description of the Related Art Usually, a headlamp is mounted above a bumper in front of a hood of a vehicle. Large space is required to place the engine and other vehicle parts, and it is difficult to secure the space for the headlamps in the engine room. The reason for this is to increase the reach of the vehicle.

[0003]

However, arranging the headlamp in front of the vehicle causes the following problems. First, the probability of the headlamp breaking even during a mild vehicle collision increases.

[0004] Secondly, it tends to become dirty when traveling in rainy weather. According to the aerodynamic analysis, since a positive pressure acts on the headlamp mounted in front of the vehicle, rain, muddy water and the like easily adhere. Third, it is difficult to attach a flat camber. In recent years, the front corner of a vehicle is often designed in an arc shape in order to reduce aerodynamic resistance. In this case, the farther the headlamp is located, the more the arc-shaped front corner is forced to move forward, resulting in a longer overall vehicle length or front overhang.

An object of the present invention is to solve such a problem.

[0006]

According to the present invention, a tower member that covers a front suspension in an engine room and a front side frame that extends in the front-rear direction and is disposed on a side of the tower member. A headlamp mounting structure for a vehicle is provided in which a headlamp is mounted, and the hood is provided with an opening that does not cover at least a light emitting surface of the headlamp when the hood is closed.

By arranging the headlamp behind the conventional headlamp mounting position,
Although the above problem can be solved, the present invention is not limited to this, and can also have the following advantages. conventionally,
Although the headlamps are arranged on the left and right of the radiator alongside the radiator, the space on the left and right of the radiator is vacated by disposing the headlamps behind according to the present invention. For this reason, the radiator can be moved to either the left or the right, and the condenser which has been conventionally arranged rearward in the front-rear direction with the radiator can be arranged side by side with the radiator. As a result, the overall length of the vehicle or the front overhang can be reduced.

Further, conventionally, the radiator has been extended in the vehicle width direction and connected to the left and right front side frames at the lower ends thereof. It was mounted and supported on one cross member. The headlamp is also No. Supported by one cross member. In the present invention, since the headlamp is disposed behind the conventional mounting position,
No. Only the radiator is to be arranged on the 1 cross member, but if only the radiator is supported, the shroud upper panel (extends in the vehicle width direction above the No. 1 cross member, the left and right front side frames It suffices to support it by suspending it from the connected members). That is, in the headlamp mounting structure according to the present invention, the conventionally used No. 1 lamp is used. Eliminates the need for one cross member.

From such a viewpoint, one embodiment of the present invention is characterized in that the radiator is arranged so as to overlap with the extension of the front side frame in front of the engine room. In addition, the conventional No. Although the first cross member had a function as a member for supporting the engine mount, as described above, in the headlamp mounting structure according to the present invention, No. 1 cross member was used. One cross member is not required. For this reason, in the present invention, no. A cowl box is used as an engine mount support member instead of one cross member.

That is, in one embodiment of the present invention,
The engine mount is connected to the cowl box. Further, in one embodiment of the present invention, the head lamp is mounted on the tower member via a tower bar member extending in the vehicle width direction for connecting the left and right tower members.

That is, the headlamp is attached to the tower bar member in advance, and then attached to the tower member while being attached to the tower bar member. By unitizing in this manner, the left and right headlamps can be attached to the tower member in one step.

FIG. 1 is a perspective view showing an embodiment of a headlamp mounting structure for a vehicle according to the present invention. The outer periphery of the engine room is defined by a pair of left and right front side frames 1A, 1B extending in the front-rear direction of the vehicle, and a shroud upper panel 2 extending in the vehicle width direction and connecting the front side frames 1A, 1B at the front end of the vehicle. I have.

The engine 3 is located almost in the center of the engine room.
Are arranged horizontally, and strut-type front suspensions (not shown) are arranged on both sides of the engine 3 in the vehicle width direction. The front suspension is surrounded by strut towers 4A and 4B that are part of the body,
Only its upper end protrudes upward from the strut towers 4A, 4B and is fixed to the body. As shown in FIG. 1, the strut towers 4A, 4B are arranged on the sides of the front side frames 1A, 1B.

A strut tower bar 5 extending in the vehicle width direction is bridged between the pair of right and left strut towers 4A and 4B. The strut tower bar 5 is an upper end of a front suspension projecting upward from the strut towers 4A and 4B. Are linked. The strut tower bar 5 has a connecting bar 6 extending forward of the vehicle on the side of the engine 3, and the connecting bar 6 is connected to the shroud upper panel 2.

The connecting bar 6 is provided with a spare tire fixing screw 8 for fixing the spare tire 7. The spare tire 7 is attached to a fixing screw 8 via a long bolt member 9, and is supported on the strut tower bar 5 and the connecting bar 6. The headlamps 10A and 10B are connected to the strut tower 4 via brackets 11A and 11B.
A and 4B are mounted on front side frames 1A and 1B via brackets 11C and 11D.

FIG. 2 shows a state in which the hood 12 used in the headlamp mounting structure shown in FIG. 1 is closed. The bonnet 12 is fixed to the vehicle body by a striker (not shown) attached to the bonnet 12 engaging with a pair of lock mechanisms 12A attached to the shroud upper panel 2. On the bonnet 12, the light irradiation surfaces 13A, 1 of the headlamps 10A, 10B are provided.
An opening 14 for exposing only 3B is formed. As shown in FIG. 2, when the bonnet 12 is closed, only the light irradiation surfaces 13A and 13B are visible from the outside.

As described above, since a positive pressure is generated at the position X1 (see FIG. 2) where the headlamp is conventionally mounted, rainwater or muddy water easily adheres. On the other hand, since the mounting position X2 of the headlamp in the present invention is a position where a negative pressure is generated, rainwater or muddy water does not adhere. As shown in FIG. 1, a radiator 15 and a condenser 16 are mounted below the shroud upper panel 2 in parallel in the vehicle width direction. The radiator 15 is arranged on the left side to a position overlapping with the extension of the front side frame 1A.

Conventionally, headlamps were mounted on the left and right sides of the radiator 15, so the condensers 16 were arranged rearward in the front-rear direction of the radiator 15. However, since the headlamps 10A and 10B were arranged behind the conventional, Such a leftward arrangement is now possible. Along with this, the conventionally used No. 1 cross member 17
(Indicated by the broken line in FIG. 1) is no longer necessary. However,
No. Since the first cross member 17 was also used as a support member of an engine mount for supporting the engine 3, in the present embodiment, No. 1 1 cross member 17
Instead, the cowl box 18 is used as an engine mount support member.

The cowl box 18 is a member having a closed cross section 19 as shown in FIG. 3, and further, as shown in FIG.
It extends in the vehicle width direction and connects the left and right front frames 1A, 1B. The cowl box 18 and the engine 3 are connected by a torque stopper 20. This torque stopper 20 functions as an engine mount. The torque stopper 20 is fixedly attached to both the cowl box 18 and the engine 3.
By being twisted clockwise or counterclockwise about the mounting end on the side, it is absorbed by the torque stopper 20.

As shown in FIG. 4, first, the headlamps 10A, 10B (only 10B is shown) are attached to the strut tower bar 5, and in this state, the strut tower bars 5 are attached to the strut towers 4A, 4B (only 4B is shown). It is also possible to attach to. In this way, by attaching the headlamps 10A and 10B to the strut tower bar 5 in advance, a pair of headlamps can be attached to each of the strut towers 4A and 4B in one step, and the headlamps can be individually attached to each strut tower. Work efficiency can be increased as compared with the case where the device is mounted on a vehicle.

Further, as shown in FIG. 1, the lens covers 21A and 21B attached to the front of the headlamps 10A and 10B may be previously attached integrally with the headlamps 10A and 10B, or FIG. As shown in the figure, the head lamps 10A, 1B are mounted on the reinforcing members 22 of the front side frames 1A, 1B in advance.
You may make it unite when 0B is attached.

As described above, in the vehicle headlamp mounting structure according to the present invention, the headlamp is disposed on the front suspension rearward of the conventional headlamp mounting position. This has the three effects of increasing the possibility that the headlamp will not break even in a light collision, making it less likely to become dirty even when running in rainy weather, and making it easier to attach a flat camber without lengthening the overall length or front overhang. Can be achieved.

Furthermore, in addition to these effects, the following effects can also be obtained. According to the present invention, the radiator can be arranged to be shifted to the left or right and the condenser and the radiator can be arranged side by side in the vehicle width direction. Therefore, from this point as well, the overall length or the front overhang can be shortened. In addition, along with this, the conventionally used N
o. Eliminates the need for one cross member.
