Description

Cargo compartment reinforcement structure of wagon type vehicle {REINFORCING STRUCTURE OF FREIGHT CHAMBER FOR WAGON TYPE AUTOMOBILE}

The present invention relates to a cargo compartment reinforcement structure that can improve the rigidity against torsional stress in the cargo compartment installed in the rear of the wagon vehicle.

In general, in the case of a passenger car, the body of the vehicle is divided into an engine room, a boarding space, a trunk, and the like so that engine noise and noise from the trunk are not introduced into the interior of the vehicle.

That is, as shown in Fig. 3, the engine room E and the room I are blocked by the cowl panel C, and the room I and the trunk T are package trays P and rear seats ( It is blocked by (not shown).

Of course, the cowl panel (C) and the package tray (P) and the like serves to block the interior (I) and the engine room (E) and the trunk (T) and at the same time the front (FS), rear strut housing (RS). When the body is subjected to torsional stress by the impact force on the road surface applied to the body through)) to support it.

Here, a typical wagon-type vehicle does not form a separate trunk T at the rear of the vehicle, and a cargo compartment communicating with the vehicle interior is formed, which is the vehicle interior I and the trunk (as shown in FIG. 4). The package tray P separating the T) is not formed, and the cargo compartment is formed in the state where the rear strut housing RS is exposed in the cargo compartment M.

Of course, the cargo compartment (M) and the vehicle interior (I) is separated only by a part of the rear seat (not shown, only the bottom and open top).

Here, the impact from the road surface is transmitted to the rear strut housing (RS) through the strut assembly, the impact force is dispersed and absorbed in the strut housing for supporting the strut assembly, side members and rear floors coupled thereto.

That is, as shown in FIG. 5, the housing cover 50 supporting the upper end of the strut assembly S, the housing inner panel 51 welded to the housing cover 50 and installed upright on the cargo compartment M side. ), A side member 52 coupled to the bottom surface of the housing inner panel 51 and disposed in the front and rear direction of the vehicle, and a rear floor 53 coupled to the upper surface of the side member 52, The impact force F applied through the strut assembly S is absorbed while acting as a torsional stress T.

However, when the impact force applied through the strut assembly and the torsional stress generated by the side member and the rear floor are absorbed by the side member and the rear floor as described above, the excessive stress is generated in P, which is a combination of the inner housing, the side member, and the rear floor. In addition to this, there is a problem in that noise and damage are generated due to weak body torsional rigidity at the cargo compartment location.

That is, in a wagon type vehicle, it is not possible to install a component such as a package tray capable of withstanding rear torsional stresses like a passenger car, so that the rigidity against torsional stress is relatively lower than that of a passenger car. It happens.

Accordingly, an object of the present invention is to solve the above problems, to provide a cargo compartment reinforcement structure of the wagon-type vehicle that can prevent the damage or noise of the cargo compartment body caused by the low torsional rigidity of the cargo compartment in the wagon type vehicle. .

In order to achieve the above object, the present invention provides a cargo compartment reinforcement structure of a wagon type vehicle including a rear strut housing and a rear floor coupled to an inner housing which is an inner side of the housing.

The first reinforcing member coupled to the housing inner panel in a vertical direction and configured to form a predetermined space between the housing inner panel and the first reinforcing member, coupled to the bottom surface of the first reinforcing member, and coupled to the rear floor upper surface and the second reinforcing member. It is characterized in that it comprises a third reinforcing material is coupled to the upper surface to form a corner portion.

1 and 2 are a schematic perspective view showing a cargo compartment reinforcement structure of a wagon-type vehicle according to the present invention and a cross-sectional view taken along line BB, which is installed between the rear strut housing inner panel 51 and the rear floor 53 and also includes a strut housing ( Reinforcement means is provided in the orthogonal direction with respect to the direction of the torsional stress T applied to S) to form the space 1 between the strut housing inner panel 51 to withstand the torsional stress.

The reinforcement means is coupled to the housing inner panel 51 in the vertical direction, and is configured to form a predetermined space 1 between the housing inner panel 51 and the first reinforcement material. It is coupled to the bottom of (2) and is coupled to the upper surface of the rear floor 53, the cross section is composed of a third reinforcing material (4) which is coupled to the upper surface of the second reinforcement (3) having a '형상' shape to form a corner portion.

That is, the first, second, third reinforcement (2, 3, 4) is configured to reinforce the P portion, which is a conventional weak portion, and the second reinforcement (3) to reinforce the rear floor 53 It is composed.

Referring to the operation and effect of the present invention as described above, when the wagon-type vehicle is coupled to the first, second, third reinforcement (2, 3, 4) as described above, bumping in the strut assembly (S) ( BUMPING) is transmitted to the housing cover 50.

The impact force F transmitted to the housing cover 50 acts as a torsional stress T that pushes the housing inner panel 51 into the vehicle, and the torsional stress T is applied to the first reinforcing material 2.

At this time, the first reinforcing material (2) is not only installed upright in the housing inner panel 51, but also provided with the housing inner panel 51 and a predetermined space (1), the rigidity against the torsional stress T described above This becomes very loud.

When the torsion stress T is applied to the first reinforcing material 2, the torsional stress T is transmitted to the third reinforcing material 4 coupled thereto, and the second reinforcing material 3 is transferred to the second reinforcing material 3. Because of this '∩' shape, the above-described torsional stress T can be appropriately absorbed.

That is, when the torsional stress T applied from both strut housings acts as a bending force of the second reinforcement 3, the first, second, and third reinforcement 2, 3, and 4 described above are dispersed and absorbed. In addition, it is delivered to the rear floor 53 and the side member 52.

In particular, since the second reinforcing material (3) is manufactured in a shape that can withstand the torsional stress T best, such as the shape of the cross section '∩', the first, second, third reinforcing materials (2, 3) , The stress dispersion and absorption effects in 4) can be doubled.

As described above, the torsional stress T transmitted to the first, second, and third reinforcement materials 2, 3, and 4, the rear floor 53, and the side member 52 is dispersed and absorbed into the above-described parts. The torsional stress T applied to the cargo compartment M is to prevent the body from being deformed / damaged.

In particular, the first, second, third, and reinforcing materials 2, 3 described above, in which the torsion stress T is concentrated in the P portion, which is a coupling portion of the housing inner panel 51, the rear floor 53, and the side member 52, is concentrated. , 4) can be prevented from deformation and breakage in this part and the noise generated therefrom.

As described above, the present invention installs reinforcing means composed of first, second, and third reinforcement materials in the corner portion between the strut housing and the rear floor of the cargo compartment of the wagon type vehicle, thereby absorbing the impact force due to bumping applied from the strut assembly, and the cargo compartment body. There is an advantage that can prevent the damage, deformation, etc. and thus the noise.
