Description

[Detailed description of the invention] (Field of industrial application) This invention is particularly suitable for mid-ship vehicles, etc., which have an engine room at the rear of the passenger compartment, and furthermore, the air intake to the engine room is connected to a strut tower. The present invention relates to a vehicle body structure of an engine room section of a vehicle that is located at the front of the vehicle.

(Prior Art) As a conventional engine room part vehicle body structure, for example, Japanese Utility Model Application Publication No. 49-60421 is known. This publication describes a structure in which member side uppers and member side lowers extend in the front-rear direction on the left and right sides of an engine room, and a hood rigid panel is joined between both member sides.

(Problem to be solved by the invention) By the way, in such a car body structure, for example, as in the car body structure shown in Japanese Patent Application Laid-open No. 55-152673, an air intake for taking air into the engine compartment is installed in the hood rigid panel. When the inlet is opened, the only thing that connects both member sides near this air intake is the panel, so the rigidity of the vehicle body near this air intake is low, and furthermore, the input force in the event of a rear-end collision is very low in this area. The problem was that it was not distributed.

(Means for Solving the Problems) The present invention was made with the purpose of solving the above-mentioned problems.To achieve this purpose, the present invention includes a vehicle body at the left and right lower portions of the passenger compartment. Along with being provided with side sills extending in the front-rear direction,
A vehicle in which rear pillars are erected at the left and right rear ends of the vehicle interior, an engine room is provided at the rear of the vehicle interior, and a wheel house and a strut tower are provided on both left and right sides of the engine room, Member side lowers are provided at the lower left and right sides of the engine room, and are offset from the center side in the vehicle width direction by the wheel house and extend from the rear part of the side sill to the bumper reinforcement at the rear end of the vehicle body. A member side upper extending from the rear of the rear pillar toward the rear of the vehicle body is provided at a distance above the member side lower and at approximately the same height as the upper height of the strut tower, and the member side upper extends from the rear of the rear pillar to the rear of the vehicle body. An air intake port is opened between both member sides behind the rear pillar, and a strut housing panel including the strut tower is provided rearward from the air intake port, and the strut housing panel connects the member side top and The member side lower is connected, and a reinforcement connecting the member side upper and the member side lower is provided at the air intake side end of the strut hanging panel with the upper end inclined toward the rear pillar side. The method is characterized by

(Function) Therefore, in the engine room body structure of the vehicle of the present invention, since the reinforcement connecting the member side upper and member side lower is provided at the air intake side end of the strut housing panel, the air intake Even if the entrance is open, input to the strut tower portion is received by the member side upper and member side lower. Therefore, the rigidity of the vehicle body can be increased.

In addition, because the upper end of the reinforcement is tilted toward the rear pillar, in the event of a rear collision of the vehicle, the impact force directed from the rear to the front of the member side lower from the bumper reinforcement is split at the lower end of the reinforcement and is directed toward the member side lower. It is transmitted to the upper part, and the input is distributed upward and downward to the rear pillar. Therefore, a strong vehicle body can be obtained.

In addition, if the upper end of the reinforcement is connected to the member side atsupa in front of the lower end,
A force directed from the rear to the front of the member side lower is more easily transmitted to the member side upper side than when the members are connected at the rear.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.
First, the configuration of the embodiment will be explained.

The engine room body structure of the example vehicle is as follows:
As shown in FIG. 1, it is applied to the vehicle body P,
Trunk room 10, member side atsupa 20,
The main components are a member side lower 30, a strut housing panel 40, and a reinforcement 50.

In FIG. 1, vehicle body outer panel members such as doors, rear fenders, trunk lids, and engine hoods are omitted.

First, the vehicle body P will be described. The vehicle body P has a passenger compartment 1, an engine compartment 2, and a trunk compartment 10 arranged in this order from the front side, and is formed in a midship type.

Side sills 3 extend in the longitudinal direction of the vehicle body at the left and right lower portions of the vehicle interior P, and a rear pillar 4 is erected from the rear end of the side sills 3. Further, the vehicle compartment 1 and the engine compartment 2 are separated by a partition wall 5.

The trunk room 10 is arranged at the rear end of the vehicle body, and is formed into a box shape surrounded by a front wall 11, left and right side walls 12, a rear wall 13, and a floor 14, and has an opening 15 at the top. At the upper and lower ends of the front wall 11 of this trunk room 10, E
As shown in FIG. 7 which is a -E cross section, a cross member upper 16 and a cross member lower 17 each having a closed cross section are provided.

On both the left and right sides of the engine room 2, first,
As shown in FIG. 2, a member side upper 20 and a member side lower 30 each having a U-shaped cross section extend in the front-rear direction.

The member side upper 20 is formed in a box closed cross-sectional shape with a strut housing panel 40 (described later), extends to approximately the same height as the upper part of the strut tower 41 (described later), and has its front end connected to the top and bottom of the rear pillar 4. It is connected approximately in the center of the direction, and its rear end is joined to the front wall 11 of the trunk room 10.

The member side lower 30 has a front end integrally connected to the side sill 3, a rear end joined to the floor 14 of the trunk room 10, and a rear end connected to the bumper reinforcement 6, and further includes:
This member side lower 30 is shown in FIG. 4, which is a cross section taken along B-B, and FIG. 5, which is a cross section taken along C-C.
It is provided offset to the center side in the width direction of the vehicle body by the amount of the wheel house (not shown). As shown in FIG. 7, an extension part 32 is connected to the member side lower 30 so as to be inserted into the rear part of the main body part 31. A flange 33 is formed to be joined to the front wall 11, and the extension part 32 is formed to deform more easily than the main body part 31 in response to a load input from the rear direction of the vehicle body.

The strut housing panel 40 includes a first,
As shown in Figures 4 and 5 and Figure 6, which is a sectional view taken along line DD, a strut is provided to be joined between the member side upper 20 and the member side lower 30, and accommodates a strut (not shown) in the intermediate portion. A tower 41 is formed. An air intake port 60 for introducing air into the engine room 2 is opened between the strut housing panel 40 and the rear pillar 4, and an air intake port 42 for an intercooler is provided at the rear of the strut housing panel 40. This strut housing panel 40, which is open, forms part of the box closed section of both member sides 20, 30, as shown in FIGS.

As shown in FIG. 1, a reinforcement 50 connecting the member side upper 20 and the member side lower 30 is provided at the end of the strut housing panel 40 on the air intake port 60 side.
The reinforcement 50 is joined to the strut housing panel 40 to form a box closed cross section, as shown in FIG. The upper end portion, which is the connection position with the pad 20, is inclined so as to be located on the rear pillar 4 (vehicle front) side and outside in the vehicle width direction with respect to the lower end portion.

Next, the operation of the embodiment will be explained.

In the engine room body structure of the vehicle according to the embodiment of the present invention, the reinforcement 50 connecting the member side upper 20 and the member side lower 30 is provided at the end of the strut hanging panel 40 on the air intake port 60 side. Even if the air intake port 60 is open, the input to the strut tower 41 portion can be received by the member side upper and member side lower 30. Therefore, the rigidity of the vehicle body can be increased. In this case, especially Rainforce 50,
As shown in FIG. 4, this reinforcement 50 is provided at an angle so that the upper end is disposed outside the lower end in the vehicle width direction, so that the input to the upper part of the strut tower 41 is limited. N (Figure 5)
This acts to resist the component force N1 toward the center of the vehicle body P, resulting in a vehicle body P with even higher vehicle body rigidity.

Furthermore, in the event of a rear-end collision of the vehicle, the trunk compartment 10 and the extension portions 32 of the member side lower 30 are deformed to absorb the impact. Further, the input from the bumper reinforcement 6 to the main body portion 31 of the member side lower 30 is distributed to the member side upper 20 side by the reinforcement 50, and the input to the rear pillar 4 is distributed vertically. Therefore, a strong vehicle body P can be obtained.

As shown in FIG. 1, the reinforcement 50 is inclined so that the upper end portion connected to the member side upper 20 is located closer to the rear pillar 4 than the lower end portion connected to the member side lower 30. Therefore, input from the rear to the front of the member side lower 30 is easily transmitted to the member side upper 20 via the reinforcement 50.

As explained above, in the engine room part vehicle body structure of the embodiment, the effect of obtaining a highly rigid vehicle body P in the vicinity of the air intake port 60 and the strut tower 41, and
This provides the effect that impact energy can be easily absorbed in the event of a rear collision, and a strong vehicle body P can be obtained.

Although the embodiment of the present invention has been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment. It may be of a shape that does not have a trunk room at the rear.

Moreover, the member side upper and member side lower are not limited to the embodiments in terms of their cross-sectional shapes and how they are connected to the trunk room or the like.

Further, in the embodiment, the extensions of the trunk room and the member side lower are deformed to absorb impact, but the means for such an impact absorption structure and the presence or absence of this structure are not limited to the embodiment.

(Effect of the invention) As explained above, in the vehicle engine room body structure of the invention, the member side upper and member side lower are connected to the air intake side end of the strut hanging panel. Since the rain force is provided with the upper side inclined toward the rear pillar side, even if the air intake port is opened in the strut housing panel, the input to the strut tower portion can be received by the member side upper and member side lower. Further, the effect of increasing the rigidity of the vehicle body around the strut tower and the air intake port, and the effect of obtaining a strong vehicle body that is resistant to rear-end collisions can be obtained at the same time.
