Description

The present invention relates to a vehicle body front structure, and more particularly to a structure for appropriately discharging water such as rainwater flowing down a windshield to the outside of the vehicle.

Generally, a vehicle such as an automobile has a structure for discharging water such as rainwater that has flowed down the front window to the outside of the vehicle. For example, a cowl is provided on the lower edge of the front window in the vehicle width direction, and the cowl is fixed to an upper frame constituting the vehicle body at both ends thereof. The water flowing down the front window flows down the cowl to the side of the vehicle, passes through the inside of the upper frame, and is drained to the outside of the vehicle.

Specifically, an opening is provided at the joint between the apron upper member (upper frame) and the cowl extending in the vehicle width direction to penetrate the inner wall of the apron upper member and communicate the inside of the cowl and the inside of the apron upper member. The water that has entered the cowl is drained into the apron upper through the opening, drained downward from the drain hole provided in the bottom wall of the apron upper member, and drained along the fender liner to the outside of the vehicle. (See Patent Document 1).

Japanese Patent No. 3965957

By the way, the position of the drainage hole provided in the upper frame varies depending on the vehicle. However, since in-vehicle devices such as headlamps are arranged in the vicinity of the front end of the vehicle in front of the upper frame, the drain holes are installed at positions where drainage is not applied to these in-vehicle devices, particularly electrical components. However, due to the structure and layout of the vehicle, for example, a drain hole may be provided near the front end of the upper frame on the vehicle front side.

In addition, in the painting process during vehicle manufacturing, the end of the upper frame on the front side of the vehicle is often opened separately from the drain hole in order to drain the electrodeposited liquid that has entered the upper frame. Even when the portion is closed, a gap for discharge is formed.

In any configuration, in the case of a vehicle having a drainage route for discharging water such as rainwater to the outside of the vehicle via the inside of the upper frame, the end portion of the upper frame on the front side of the vehicle when the vehicle is tilted or the like. It is assumed that the water inside is discharged from the opening (gap) of. If the water inside the upper frame is discharged from the front end of the vehicle, the water may be scattered toward the front of the upper frame, and the in-vehicle device arranged there may be flooded. In particular, in the case of electrical components such as headlamps, there is a risk of failure if the wiring portion or the like is exposed to water.

In recent years, with the diversification of vehicle designs, some headlamps are placed at a position lower than the upper frame, specifically, at a height around the front of the wheel house (splash shield). In a vehicle with such a design, there was room for improvement because the layout was such that the headlamps were more easily exposed to water due to the water discharged from the upper frame.

The present invention has been made in view of such circumstances, and provides a vehicle body front structure capable of suppressing water discharged from the upper frame from scattering to the front of the upper frame. The purpose.

One aspect of the present invention that solves the above problems is a frame member forming a vehicle body including an upper frame in which a base end portion on the rear side of the vehicle is fixed to a front pillar and extends forward of the vehicle, and an outer side of the upper frame. a fender panel which is arranged to, provided in the vehicle width direction and a bracket member which connects the frame member and the fender panel, wherein the upper frame has an internal drainage path that is formed Rutotomoni, front An opening is formed in the portion, and the bracket member extends to the front of the opening at the tip end portion of the upper frame, and the upper end side of the bracket member or a member fixed to the bracket member is the front end of the upper frame . It is in the vehicle body front structure of a vehicle, characterized in that it is formed so as to be located above the lower end of the opening of the portion .

Here, when the splash shield arranged on the lower side of the upper frame is provided, it is preferable that the lower end side of the bracket member is fixed to the splash shield.

When the splash shield is provided on the lower side of the upper frame, the splash shield has a bead portion protruding upward on the vehicle front side of the bracket member along the bracket member. It is preferable that it extends in the width direction.

Further, it is preferable that a headlamp is provided in front of the tip end portion of the upper frame, and the bracket member is provided between the upper frame and the headlamp.

Further, it is preferable that the fender panel, the headlamp, and the splash shield arranged under the upper frame are positioned and fixed with respect to the bracket member.

The left and right upper frames 11 are connected to each other by a cowl top panel 12 extending in the vehicle width direction. Although not shown, an opening is formed in the connecting portion of the upper frame 11 with the cowl top panel 12. Then, water such as rainwater that has flowed into the cowl top panel 12 flows into the inside of the upper frame 11 through this opening, and is discharged to the outside of the vehicle through the inside of the upper frame 11. That is, the upper frame 11 forms a drainage path inside the upper frame 11 for discharging rainwater or the like to the outside of the vehicle.

In the present embodiment, the bottom surface of the upper frame 11 is inclined so as to be lowered toward the rear side of the vehicle. Therefore, water such as rainwater that has flowed into the upper frame 11 is usually flowed to the rear side of the vehicle along the bottom surface of the upper frame 11 and discharged to the outside of the vehicle. However, in the present embodiment, the front end portion of the upper frame 11 is opened so that the electrodeposition liquid and the like are smoothly discharged in the painting process during vehicle manufacturing (see FIG. 6). Therefore, depending on the inclination of the vehicle, water such as rainwater may be discharged from the front end portion of the upper frame 11.

Further, a pair of left and right front side members 13 extending in the front-rear direction of the vehicle are arranged at positions inside the front pillar 10 in the vehicle width direction and below the upper frame 11. The front side member 13 and the tip end side (the other end side) of the upper frame 11 are connected by a metal fender shield 14 provided inside the engine room 3. At the end of the fender shield 14 on the front side of the vehicle, an extension portion 14a extending outward in the vehicle width direction is provided. The extension portion 14a is arranged in front of the tip end portion (the other end portion) of the upper frame 11 with a predetermined gap, and extends so as to overlap the upper frame 11 in the front-rear direction of the vehicle (FIG. 7). reference). A bracket member 16 described later is fixed to the extended portion 14a. A spring house panel 15 forming a tubular spring house is provided behind the fender shield 14, and the spring house panel 15 is also fixed to the upper frame 11.

By the way, as shown in FIG. 5, a fender panel 4 is mounted on the outside of the upper frame 11, and the fender panel 4 is connected to the upper frame 11 and is a bracket formed of a metal plate. It is also connected to the fender shield 14 via the member 16. In the present embodiment, the fender panel 4 is fixed to the bracket member 16 by a bracket mounting hole 4a provided at an end portion on the front side of the vehicle. The fender panel 4 is positioned and fixed to a frame member such as the upper frame 11 with reference to the bracket member 16.

The frame member is a member that forms the skeleton of the vehicle body. For example, each member of the front pillar 10, the upper frame 11, the front side member 13, and the fender shield 14 is included in the frame member.

Further, the left and right ends of the front bumper 8 mounted on the front surface of the vehicle 1 are positioned and connected to the fender panel 4. In the present embodiment, as shown in FIG. 5, the fender panel 4 is formed with bumper mounting holes 4b at the front end of the vehicle, and the left and right ends of the front bumper 8 are fenders with the bumper mounting holes 4b. It is positioned and connected to the panel 4. Since the fender panel 4 is positioned with reference to the bracket member 16 as described above, the front bumper 8 is also positioned with reference to the bracket member 16 via the fender panel 4.

Here, as shown in FIGS. 6 and 7, the bracket member 16 extends in the vehicle width direction in front of the tip of the upper frame 11 to connect the fender panel 4 and the fender shield 14.

Further, the bracket member 16 has a shape in which the upper end side thereof extends in front of the tip portion (opening 11a) of the upper frame 11 to a position where it reaches the height of the tip portion. In other words, the upper end of the bracket member 16 is located at the lower end of the tip of the upper frame 11, more specifically, in front of the lower edge of the opening 11a of the tip and at a height similar to the lower end of the tip. Has been done. Then, it is desirable that the upper end of the bracket member 16 is formed so as to be located above the lower end of the tip end portion of the upper frame 11, that is, to be located in front of the opening 11a of the tip end portion of the upper frame 11. In the present embodiment, the upper end of the bracket member 16 is at the same height as the lower end of the tip end portion of the upper frame 11, but the extended portion 14a of the fender shield 14 to which the bracket member 16 is fixed and integrated is fixed. The upper end of the upper frame 11 is located above the lower end of the tip portion of the upper frame 11. That is, also in the configuration of the present embodiment, the upper end of the bracket member 16 is substantially positioned above the lower end of the tip end portion (opening 11a) of the upper frame 11. Further, since the bracket member 16 is overlapped with the extending portion 14a of the fender shield 14, it is arranged with a predetermined gap with respect to the tip end portion (opening 11a) of the upper frame 11.

On the other hand, the lower end side of the bracket member 16 extends downward, and in the present embodiment, it is fixed to the splash shield 17 provided on the lower side of the upper frame 11. The splash shield 17 is a member that forms a wheel house 6 on which the front wheels 5 are arranged. The splash shield 17 is formed of, for example, a resin material and is attached to an upper frame 11 or a fender panel 4 which is a frame member, but is further fixed to a bracket member 16 and is based on the bracket member 16. It is positioned as.

Further, the splash shield 17 is provided with a bead portion 18 projecting upward on the vehicle front side of the portion where the bracket member 16 is fixed (see FIG. 6). The bead portion 18 extends along the bracket member 16 in the width direction (vehicle width direction) of the splash shield 17. The length of the bead portion 18 (length in the vehicle width direction) is not particularly limited, but it is preferably formed as long as possible.

Further, the support portion 7a of the headlamp unit 7 arranged on the front side (front side of the vehicle 1) of the bracket member 16 is fixed to the bracket member 16 via the lamp fixing plate 19 (FIG. 2 and the like). reference). The bracket member 16 is connected to the fender shield 14 or the like with the lamp fixing plate 19 positioned and fixed in advance. Then, the support portion 7a of the headlamp unit 7 is attached to the lamp fixing plate 19 fixed in this way, positioned, and fixed to the frame member. That is, the headlamp unit 7 is also positioned with reference to the bracket member 16 like the splash shield 17 and the like.

As described above, in the vehicle body front structure of the present embodiment, the bracket member 16 connecting the fender panel 4 and the fender shield (frame member) 14 is extended to the front of the tip portion of the upper frame 11 and the bracket member 16 thereof is extended. The upper end is set to a height that reaches the upper frame 11, and the lower end side thereof is extended and fixed to the splash shield 17.

With such a configuration, a vertical wall formed by the bracket member 16 is formed from the splash shield 17 to the front of the tip portion of the upper frame 11, so that water such as rainwater can be collected by the cowl as shown by an arrow in FIG. Even when the water flows from the top panel 12 through the upper frame 11 and flows out from the vicinity of the tip end portion (opening 11a) of the upper frame 11, the bracket member 16 regulates the flow to the front side of the vehicle and downwards along the surface of the bracket member 16. After being surely flushed to the upper surface of the splash shield 17, it flows in the vehicle width direction and is discharged to the outside of the vehicle. Therefore, since the scattering of water to the front of the upper frame 11 is suppressed, it is possible to suppress the adhesion of rainwater or the like to various in-vehicle devices arranged in front of the splash shield 17, and various in-vehicle devices due to water reception can be suppressed. It is possible to suppress equipment failure. In particular, in a vehicle having a layout in which the headlamp unit 7 is arranged at a relatively low position, water exposure to the wiring portion of the headlamp unit 7 can be suppressed, which is very effective.

Further, in the present embodiment, the bead portion 18 is provided on the front side of the vehicle with respect to the bracket member 16 of the splash shield 17, so that the water (rainwater, etc.) flowing out from the upper frame 11 flows more reliably in the vehicle width direction. Can be. For example, even when the water flowing out from the upper frame 11 flows out from between the bracket member 16 and the splash shield 17 to the front side of the vehicle, the groove portion 20 formed between the bracket member 16 and the bead portion 18 (see FIG. 6). ), Water will flow in the width direction of the vehicle and be discharged. Therefore, it is possible to more reliably suppress the adhesion of rainwater or the like to various in-vehicle devices in front of the upper frame 11.

Further, in the present embodiment, as described above, each part (so-called fixture) such as the fender panel 4, the headlamp unit 7, and the front bumper 8 is positioned with reference to the bracket member 16, so that the relative positions of the parts are relative to each other. Can be determined relatively easily and with high accuracy.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be appropriately modified without departing from the spirit of the present invention.

For example, in the above-described embodiment, the configuration in which the lower end side of the bracket member is fixed to the splash shield is illustrated, but the bracket member does not necessarily have to be fixed to the splash shield. For example, when a bead portion is formed on the splash shield, even if there is a gap between the bracket member and the splash shield, it is not possible to allow rainwater or the like to flow in the vehicle width direction along the bead portion. it can.

Further, the bead portion of the splash shield does not necessarily have to be provided. If the bracket member and the splash shield are fixed with almost no gap, the bracket member can sufficiently suppress the scattering of rainwater and the like flowing out from the tip of the upper frame to the front of the vehicle even if there is no bead portion. it can.

Further, in the above-described embodiment, the fender panel, the headlamp unit, and the front bumper are exemplified as the parts to be positioned with reference to the bracket member, but the parts are not limited to these parts, of course.
