Abstract

PURPOSE:To secure an engine-room space by joining a front hood-ridge which has a longitudinal wall formed protrudently in offset on the outside of a car and possesses a flange portion with the upper edge part facing on the inside of the car, with a rear hood-ridge expand-forming a wheel house portion. CONSTITUTION:A rear hood-ridge 2b is formed with a wheel house portion expand-formed by cutting-out the escape hole 8 of a strut suspension and a longitudinal wall 11 having a shelf part 12 on the upper face. A front hood-ridge 2a is formed with a longitudinal wall 14 formed protrudently in offset on the outside of a car and, on its upper face, a flange portion 15 facing on the inside of the car. A hood-ridge panel 2 is constituted by lap-joining both 2a and 2b and at the same time connecting a reinforce 4 thereto. An engine-room space can be made to enlarge as much space as is formed protrudently in offset on the outside of the car, and at a time of a frontal collision, the change of only the front hood-ridge 2a is sufficient, thus making a repair work simple.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a hood ridge structure for an automobile.

Examples of conventional hood ridge structures for automobiles include those shown in FIGS. 5 to 7.

FIG. 5 shows a --shaped hood ridge structure, in which a hood ridge panel 2 with a bulging wheel house portion 1 is shown.
A strut housing 3 is joined to the wheel house part 1 of the hood ridge panel 2, and a hood ridge reinforcement 4 is joined to the outer surface of the upper part of the hood ridge panel 2 to form a closed section. Together with the side member 5 which is joined and has a closed cross section R4, strength against uplift force is ensured.

On the other hand, FIG. 7 shows a split type 7-dridge structure, in which a hood ridge front la and a hood ridge rear 1b constitute a wheel house section that is divided at the front and rear of the hood rim panel 2f'i strut housing 3. The hood ridge front la, the strut housing 3, and the hood ridge upper 6 are joined to the upper edges of the hood ridge rear 1b.A hood ridge reinforcement 4 is joined to the outer surface of the hood ridge upper 6. Yes, side member 5 and I+! ! J spit, its closure 117
The one-sided structure ensures strength against uplift forces. Note that 7 indicates a front fender (a structure similar to these is shown in, for example, Japanese Utility Model Application No. 190679/1983).

Problems to be Solved by the Invention For example, when it is necessary to replace a hood ridge that has been deformed due to a frontal collision of a vehicle, the hood ridge front 1a,
Hood Ridge Upper 6, Hood Ridge Reinforce 4
Both of them have to be replaced, which makes the replacement work difficult, and the cost of replacing one friend is also high.

In addition, in both the above-mentioned body type and split type, since the hood ridge reinforcement 4 is joined to the outside of the vehicle, the inside of the engine room is narrowed only by the closed cross section formed by the hood ridge reinforcement 4. This makes it difficult to arrange various supplementary items, especially in the area ahead of the wheel house where sufficient space is required.

Furthermore, when the present invention is adopted for a so-called long-nose type or short-nose type, in which the front part of the vehicle body is long, there is a problem in that the wheel nose and foot parts, etc. must be made separately for each type.

Therefore, the present invention has developed an automobile hood ridge structure that is easy to replace even if the vehicle is deformed or damaged due to a frontal collision, has low replacement costs, and can secure sufficient space in the engine compartment. It is something that provides.

Means to Solve the Problem The hood ridge panel has a rear hood ridge with a bulging wheel house portion, and a front hood ridge with a flange portion on the upper edge that is offset from the vertical wall outside the vehicle I11 and faces toward the inside of the vehicle. The rear hood ridge and the front hood ridge are joined by lapping the front edge of the rear hood ridge and the rear edge of the front hood ridge.

For example, in front of the hood ridge panel 9
If part 111 is deformed, it is sufficient to replace only the front hood ridge.

Additionally, the space within the engine room is expanded by the amount that the vertical wall of the front hood ridge is offset from the outside of the vehicle.

Furthermore, whether the front part of the vehicle body is a long nose type or a short nose type, the rear hood ridge can be used as a common part to change the length of the front hood ridge.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings, in which the same parts as those of the conventional structure are denoted by the same reference numerals.

In Figures 1 to 4, 2 indicates a hood ridge panel;
This hood ridge panel 2 is divided into a rear hood ridge 2b in which the wheel house portion 1 is bulged and a front hood ridge 2a that is lapped and joined to the front edge of the rear hood ridge 2b.

The rear hood ridge 2b has the strut housing 3 flange-jointed around the escape hole 8 of the strut suspension provided in the wheel house part 1, and the gusset 10 joined to the suspension support 9 attached to the shelf part 12 on the upper edge of the vertical wall 11. The strut housing 3 is fixed by joining. Incidentally, the shelf section 12 has a flange section 1'3' formed in an upright manner.

Furthermore, a side member 5 having a closed cross-section structure is joined to the lower edge of the rear hood ridge 2b.

- On the other hand, the front hood ridge 2a is a member having a cross-section with a cross-section, and its vertical wall 14 is offset to the outside of the vehicle 111 to widen the engine room. A flange portion 15 facing toward the inside of the vehicle is formed on the upper edge.

The upper surface of the rear edge of the front hood ridge 2a is lapped and joined to the rn edge of the rear hood ridge 2b formed in this way, and the portion from the rear hood ridge 2b to the rear end of the widened part of the front hood ridge 2a is bonded to the rn edge of the rear hood ridge 2b. The U-shaped hood ridge reinforcement 4 is attached to the upper flange 4a of the hood ridge reinforcement 4 = i rear hood ridge 2
b, horizontal 7 langes 4b't at the front end of the hood ridge reinforcement 4, and joined to the flange 15 of the front hood ridge 2a, and also the lower edge flange 4c f' of the foot ridge reinforcement 4. 2b and each vertical wall 11 of the front hood ridge 2a
, 14 for installation.

Therefore, the upper edge portions of the rear hood ridge 2b and the front hood ridge 2a reaching the rear ends of the widened portions are formed with a closed cross-section structure similar to the first F edge portion to which the side member 5 is attached. .

In addition, 7 is a front fender "t" which is joined to the upper surface of the hood ridge reinforcement 4.

According to the above embodiment structure, if the front hood ridge 2a is deformed or damaged due to a frontal collision of the vehicle, for example, it is only necessary to remove and replace the front hood ridge 2a. The work is easier to perform and the replacement cost is lower than when replacing the entire panel 2.

In addition, the front hood ridge 2a is widened and offset to the outside of the vehicle, and the flange portion 15 of the upper part of the front hood ridge 2a is formed toward the inside of the vehicle I11, so it especially requires space. The space in the engine room at the front of the wheel house l is increased by the amount shown by cross hatching in Figure 4 in the vehicle width direction.
Therefore, each heel bucket device can be easily arranged. And hood ridge panel 2,
In particular, the thrust of the rear hood ridge 2b on the wheel house portion 1 is more resistant to the force than the hood ridge reinforcement 4 and the rear hood ridge, which is wider than the conventional closed section shown by cross hatching in Fig. 3. The closed r-face section between 2b and 2b makes it possible to compete with the era name, further increasing reliability in terms of strength and rigidity.

In addition, by using the rear hood ridge 2b and molding it to a certain length, for example, the front hood ridge 2akP), it can be used in so-called long-no-X type cars, so parts can be shared. Can be agglomerated.

Effects of the Invention As explained above, according to the present invention, it is possible to secure a wider space in the engine room, which makes it easier to arrange the various hammer accessories, and it is also possible to accommodate vehicles with different front lengths. For example, by replacing only the front hood ridge, the rear hood ridge can be used as a common part.
