[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a center pillar structure for a hard-top vehicle.

[0002]

2. Description of the Related Art FIG. 4 shows an example of a body structure of a hardtop vehicle. A center pillar 1 is provided between a floor and a roof on both sides of the body, as shown in FIG. Then, as shown in FIG.
, A rear side door 4 is attached via an upper hinge 2 and a lower hinge 3. A so-called belt line L is defined along the upper edge 4a of the rear side door 4.

[0003] As shown in Fig. 6, a center pillar 1 is provided between a center pillar inner 5 (inside the vehicle compartment) and a center pillar outer 6, and a center pillar lower reinforce 7 and a center pillar upper reinforce. 8, a belt anchor / reinforce 9 and a belt anchor / lower / reinforce 10 are provided. In the drawing, 11 is an upper hinge / reinforce, 1
2 is a strike retainer.

As shown in FIGS. 7 (a) and 7 (b), the above members are joined to each other at appropriate places by spot welding or the like. In particular, the belt anchor lower reinforce 10 and the center pillar lower reinforce 7 are connected on the upper side of the upper hinge 2. The center pillar / lower / reinforce 7 is formed of a relatively thin plate (a plate thickness of about 0.8 mm), and the belt anchor / lower / reinforce 10 is formed of a relatively thick plate (a plate thickness of about 1.4 mm). But,
The belt line L is set at a position close to the upper side of these connecting portions (the line AA in FIG. 6). In the center pillar 1 near the belt line L, a stress concentration portion occurs. In addition, the belt anchor reinforce is replaced with the center pillar lower reinforce 7
There is also known an integrated configuration.

[0005]

However, in the conventional center pillar structure, the connecting portion between the center pillar / lower / reinforce 7 and the belt anchor / lower / reinforce 10 is set at a position very close to the stress concentration portion. In particular, countermeasures against collisions and the like from the side of the vehicle (hereinafter referred to as side collisions) are not always sufficient. In addition, as shown by the two-dot chain line (normal state) and the solid line in FIG. 5 in the related art, there is a problem of so-called door lowering of the rear side door 4, and in order to prevent this lowering, the center pillar upper reinforce 8 is structurally provided. It had to be provided.

Furthermore, the connection between the center pillar / lower / reinforce 7 and the belt anchor / lower / reinforce 10 which is set at a position very close to the stress concentration portion has caused a so-called muffled sound (low-frequency sound). . In addition, belt anchor reinforce / center pillar lower
In the case of the reinforce 7 integrated type, there is a problem that the weight is increased.

[0007] In view of the above, it is an object of the present invention to provide a center pillar structure of a hard-top vehicle that improves the rigidity of the body and completes a countermeasure against side collision.

[0008]

The center pillar structure of the hard-top vehicle of the present invention can support a side door via an upper hinge and a lower hinge. The center pillar structure includes a center pillar inner and a center pillar outer. In between, at least a belt anchor lower reinforce and a center pillar lower reinforce are combined and configured. And in particular, Bertha Anker Lore Reinfo
And extend it to the lower side of the upper hinge.
In addition, a connecting portion of the belt anchor lower reinforce and the center pillar lower reinforce is set at an appropriate position below the upper hinge.

[0009]

According to the center pillar structure of the present invention, the belt anchor lower reinforce and the center pillar lower reinforce are provided.
The connecting portion of the reinforce is set below the upper hinge and is separated from the stress concentration portion. As a result, the rigidity can be improved, and countermeasures against side collision can be made. Therefore, the risk of breakage of the center pillar can be eliminated, and muffled noise can be significantly reduced.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 to 3, an embodiment of a center pillar structure of a hard-top vehicle according to the present invention will be described using substantially the same members as those of the prior art.
FIG. 1 is a perspective view of a main part of the center pillar structure of the present invention, and FIG.
Is an exploded perspective view thereof. The belt anchor inner reinforce 9a and the belt anchor outer reinforce 9b constitute a belt anchor reinforce 9, and the belt anchor outer reinforce 9 is formed.
Below B, Bertka Anchor Lower Reinforce 1
0 'is formed. These members are disposed between the center pillar inner 5 and the center pillar outer 6. In FIG. 2, 13 is a lower hinge.
Reinforce.

The center pillar lower reinforce 7 'made of a thin plate and the belt anchor lower reinforce 10' made of a thick plate are located at the lower side of the upper hinge 2, that is, below the upper hinge / reinforce 11 in FIG. 1, CC line). This connection state is shown in FIG. on the other hand,
FIG. 3A shows a corresponding portion of the upper hinge 2. As is clear from the drawing, the center pillar upper
Reinforce 8 (see FIG. 7B) is not provided.

According to the present invention, the connecting portions of the belt anchor lower reinforce 10 'and the center pillar lower reinforce 7' are connected to the upper hinge 2 as described above.
Is set in the lower right place. That is, center pillar 1
Is separated from the stress concentration portion at By setting the connecting portion of the two members away from the stress concentration portion as described above, the rigidity of the body can be improved, and the risk of breakage of the center pillar can be eliminated. In addition, this makes it possible to significantly reduce the muffled sound. However, compared to the case of the conventional center pillar structure, the noise can be improved by about 15%.

Further, by arranging the belt anchor / lower / reinforce 10 'made of a thick plate material so as to extend to the lower side of the upper hinge 2, it is possible to effectively prevent the door from lowering, which is conventionally indispensable. The existing center pillar upper reinforce 8 can be eliminated. In addition, Belt anchor lower reinforce 1
At the connection of the 0 'and the center pillar lower reinforce 7', the space for their joining spot welding guns is increased, and the number of spots is increased, thereby increasing the rigidity. In addition, Belt anchor / reinforce / center pillar /
Significant weight reduction can be achieved as compared with the case of the integrated lower and reinforcement.

[0014]

[Effects of the Invention] As described above, according to the present invention, the rigidity of the body is improved by separating the connecting portions of the belt anchor lower reinforce and the center pillar lower reinforce from the stress concentration portion, The collision measures can be completed. Therefore, the risk of breakage of the center pillar is eliminated, and the safety of occupants is improved.
In addition, the muffled noise can be significantly reduced, thereby providing comfort during running and the like, and further reducing the number of parts, thereby effectively reducing weight.
