Description

[Detailed description of the invention] Industrial application field This invention makes it possible to partially expand the volume of the engine room without deteriorating the sense of quality due to partial bending of the parting line, etc. This article relates to the front structure of an automobile.

BACKGROUND ART As a conventional vehicle body front structure, the one shown in FIGS. 8 and 9 has been put into practical use (see Japanese Utility Model Application Publication No. 1478/1983). That is, the vehicle body 1 is provided with a dart lower panel 4 that partitions an engine compartment 2 at the front and a passenger compartment 3 at the center. A cowl box 5 is formed along the upper portion and extends in the vehicle width direction. The cowl box 5 is
It is formed by joining a cowl top panel 8 forming the front wall 6 and the top wall 7 and a dart top panel 11 forming the bottom wall 9 and the rear wall 10, and the top wall 7 has an upper opening. 12 are formed. A cowl top grill 14 as a cowl cover having a ventilation hole 13 is covered over the upper surface opening 12, and one end of the cowl top grill 14 is connected to the upper wall 7 through a weather strip 15 as a sealing member. It is joined to the side edge of the front wall 8, and the other end is joined to the lower edge of the front window 16.
On the other hand, an engine hood 17 covering the engine room 2 is constructed by hemming a hood outer panel 18 and a hood inner panel 19 together, and is pivotally supported on the cowl box 5 via a hinge (not shown). When the engine hood 17 is closed, the weather strip 15 comes into close contact with the hood inner panel 19, thereby ensuring watertightness between the cowl box 5 and the engine hood 17, and preventing rainwater from entering the engine compartment 2. The structure is designed to prevent the intrusion of such persons.

Problems that the invention aims to solve By the way, today, due to demands such as proper control of the engine and suspension and improvement of cabin comfort, there is a tendency for the number of auxiliary parts to carry out the necessary control etc. to increase. . For this reason, engine room 2
As a result of the intensive arrangement of such auxiliary parts,
It was pointed out that the facility was overcrowded, making it difficult to place auxiliary equipment parts. Of course, if the overall volume of the engine room 2 is set sufficiently, the above-mentioned difficulty can be solved, but setting the volume of the engine room 2 sufficiently for the car body 1 is due to constraints on the design of the car body 1. Not only this, but also the living space is relatively reduced, which is not desirable. For this reason, it is possible to partially enlarge and deform the engine room 2 according to the shape of the auxiliary parts, but if the engine room is simply partially enlarged and deformed, the engine that covers the engine room 2 Food 1
7 becomes complicated, and the parting lines P ₁ , P ₂ , P ₃ between the engine hood 17 and the surrounding members do not become straight lines or curves of constant curvature as shown in the diagram, but instead take on a partially bent shape. It ends up. Therefore, due to the bent shape of the parting line, and furthermore, the fact that the engine room has been partially expanded due to the bent shape of the parting line makes it obvious from the outside, the quality of the vehicle body 1 is affected. There was a risk that this would decrease.

The present invention has been made in view of such conventional circumstances, and is intended to partially reduce the volume of the engine compartment 2 without changing the parting line around the periphery of the engine hood 17 or making it obvious in appearance. The present invention provides an automobile body front structure that can be expanded.

Means for Solving the Problems In order to solve the above problems, in the present invention, a cowl box extending in the vehicle width direction is formed at the upper rear end of the engine room of the vehicle body, and the upper surface of the cowl box In the structure in which the cowl cover is covered, an auxiliary parts arrangement space is formed in the engine room by retracting the front wall of the cowl box toward the inside of the cowl box, and the cowl cover is covered with the auxiliary parts. An extension extending over the machine parts arrangement space is formed, and a sealing member attached to one of the members and inserted between the upper surface of the extension and the lower surface of the engine hood covering the engine room is formed. Constructed to ensure watertightness.

In the above configuration, the auxiliary component arrangement space is
Since the front wall of the cowl box is deformed backward toward the inside, the volume of the engine room is partially expanded without affecting the living space of the occupants. Also, the extension portion extends to the upper surface of the auxiliary parts arrangement space, so that the auxiliary parts arrangement space is concealed by the extension portion without changing the shape of the engine hood itself.
Therefore, the auxiliary component arrangement space is not obvious from the outside, and the parting line of the engine hood does not have a partially bent shape. Furthermore, a seal member is inserted between the upper surface of the extension part and the lower surface of the engine hood, thereby reliably preventing rainwater from entering the engine compartment.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. That is, as shown in FIGS. 1 and 2, the vehicle body 20 is provided with a dart lower panel 23 that partitions an engine room 21 at the front and a passenger compartment 22 at the center. A cowl box 24 is formed along the upper rear end of the engine compartment 21 and extends in the vehicle width direction. The cowl box 24 is formed by joining a front wall 25 and a cowl top panel 29 forming an oblique bottom wall 28, as shown in FIG. 2, and the upper wall 28 has an upper opening 30. The cowl top panel 29
A rain force 31 is joined to the lower surface rearward of the upper surface opening 30. As shown in FIGS. 1 and 5, the front wall 25 is provided with a recessed portion 32 that is deformed backward toward the inside of the cowl box 24 at the side portion, thereby allowing the engine compartment 21 The front wall 25 shown in FIGS.
An auxiliary component arrangement space 33 is formed by a difference area between the general surface position of the retracting portion 32 and the retracting deformation position of the retracting portion 32. In the engine room 21, a rear half portion of a battery 34, which is an auxiliary component, is arranged so as to extend into the auxiliary component placement space 33.

A weather strip 36 is fitted onto the front joining flange 35 of the dash upper panel 27 and cowl top panel 29. The weather strip 36 is constructed by sequentially connecting first, second, and third members 38, 39, and 40, each having a welt portion 37, as shown in numbers 6 and 7. A hollow lip 41 is formed on the third member 40, a projecting lip 42 is formed on the second member 39, and the first member 38 is formed on the second member 39.
A backing plate 43 for bonding the third member 40 and the third member 40 is formed. The first member 38 is fitted from one end of the front joint flange 35 to a region past the center of the vehicle body 20 shown by the line in FIG. 1, and a second member 39 is fitted to this region. A third member 40 is fitted in a portion closer to the auxiliary component arrangement space 33 than this.

On the other hand, a rib 44 is appropriately formed in the upper surface opening 30, and a cowl top grill 45 serving as a cowl cover having a ventilation hole 60 is covered. An extending portion 46 extending upward is formed. The rear end portion of the cowl top grill 45 is close to the lower end surface of the front window 47, and the front end portion extends from the above-mentioned one end to the portion past the center of the vehicle body shown in FIG. 1 by the cowl top panel 29. The front joint flange 35 is located close to the base of the third member 40 (FIGS. 2 and 3), and on the other end side of the third member 40 (FIGS. 4 and 5). . The cowl top grill 45 is fixed to the cowl top panel 29 with resin clips (not shown).

On the other hand, an engine hood 49 covering the engine room 21 is constructed by joining a hood outer panel 50 and a hood inner panel 51, and a hood seal rubber 52 serving as a sealing member is attached to the lower surface of the hood inner panel 51. The hood seal rubber 52 is attached to the extending portion 4 when the engine hood 49 is closed as shown in FIG.
6, and the first member 38
It is located so as to be continuous with the hollow lip 41 of. Note that 53 in FIG. 3 is a bracket that is attached inside the cowl box 24 and is used to attach a wiper device.

In this embodiment with the above configuration, the auxiliary parts arrangement space 33 is formed by the retreating portion 32 that is formed by retreating the front wall 25 into the cowl box 24, so that the space for auxiliary equipment parts is engine room 21 according to the volume of auxiliary parts arrangement space 33 without affecting engine room 22.
The volume of will be partially expanded. Therefore, overcrowding of the auxiliary parts arranged in the engine room 21 is alleviated, and it becomes possible to facilitate the work of arranging the auxiliary parts and the repair work. In addition, since the extension part 46 extends over the auxiliary parts arrangement space 33, the shape of the engine hood 49 itself does not change, and the auxiliary parts arrangement space 33 extends above the extension part 46.
hidden by Therefore, the auxiliary parts arrangement space 33, which looks like a bulging part of the engine room 21, is not clearly visible in appearance, and the engine hood 49 shown in FIG.
The parting line _P3 at the rear end edge can be formed on a curved line of constant curvature without having to be partially bent. Therefore, the volume of the engine room 21 can be reduced as described above without causing disadvantages in appearance, such as the parting line P ₃ becoming partially bent or the auxiliary parts arrangement space 33 becoming clear in appearance. It becomes possible to expand. Further, a hood seal rubber 52 is provided between the engine hood 49 and the extension portion 46, and a front joint flange 35 is provided between the engine hood 49 and the extension portion 46.
and the engine hood 49 by the first member 38,
Front joint flange 35 and cowl top grill 45
A third member 40 seals the gaps between the two. Therefore, it is possible to reliably prevent rainwater and the like from entering the engine room 21, and at the same time, it also prevents the disadvantage that hot air in the engine room 21 flows out to the outside, is sucked from the cowl box 24, and enters the passenger compartment 22. This can definitely be prevented.

In the above embodiment, the hood seal rubber 52 is attached to the lower surface of the hood inner panel 51, but if it is attached to the upper surface of the extension part 46, the hood seal rubber 52 shown in FIG. It becomes possible to connect the hollow lip 41 of the first member 38 with more precision.

Effects of the invention As explained above, the invention creates an auxiliary parts placement space in the engine room of the vehicle by deforming the front wall of the cowl box backwards toward the inside of the cowl box, which has an impact on the living space. It is possible to partially expand the volume of the engine room without any problems. Therefore, overcrowding of auxiliary parts arranged in the engine room can be alleviated, and work for arranging and repairing auxiliary parts can be facilitated, thereby increasing work efficiency. Further, since the cowl top grill is formed with an extending portion that extends over the auxiliary component placement space, the auxiliary component placement space can be hidden by the extended portion without changing the shape of the engine hood itself. Therefore, the parting line of the engine hood should not be set to a curved line with a constant curvature or a straight line, so that the auxiliary parts placement space, which looks strange and looks like a bulging part of the engine room, is not visually obvious. It can be done.
For this reason, even if the above-mentioned auxiliary parts placement space is provided,
Without deteriorating the sense of quality, such as the parting line becoming partially bent or the auxiliary parts placement space causing a strange feeling becoming clear in appearance,
It becomes possible to increase the volume of the engine room mentioned above.

Furthermore, since a sealing member is inserted between the lower surface of the engine hood and the upper surface of the extension part, it is possible to prevent rainwater etc. from entering the engine room from between these two members, and also prevent the intrusion of rainwater etc. into the engine room. It is also possible to reliably prevent hot air from flowing outside and entering the vehicle interior through the cowl box.
