DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle side body structure in which a door opening / closing door provided on a side of a vehicle is opened and closed by a freestyle front door and a rear door.

[0002]

2. Description of the Related Art Conventionally, as a side body structure of a vehicle in which a door opening provided on a side portion of the vehicle is opened and closed by a freestyle front door and a rear door, for example, Japanese Patent Application Laid-Open No. Hei. There is a thing of the description.

That is, a door opening having a center pillar-less structure is formed in a side portion of a vehicle, and a front side of the door opening is supported by a front door hinge via a front door hinge so as to be openable and closable. On the rear side, a rear door is supported via a rear door hinge so as to be openable and closable.

A latch is provided on the front upper portion of the rear door, and a keeper for locking the rear door is attached to a portion of the door opening corresponding to the latch. However, if the rigidity of the above-mentioned keeper mounting portion is low, there is a problem that the amount of movement of the vehicle body and the door into the vehicle compartment at the time of a side collision is large. This becomes even more pronounced when the opening is set large.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a lock member for locking a door is provided at an upper side of a door opening, and reinforcement for connecting a door opening provided with the lock member to a roof panel is provided. By providing the member, it is possible to improve the rigidity of the door locking portion regardless of the size of the door opening, and particularly in the case of a center pillar-less vehicle, the amount of movement of the vehicle body and the door into the vehicle compartment at the time of side collision is reduced. It is an object of the present invention to provide a side body structure of a vehicle that can be suppressed.

[0006]

A side body structure of a vehicle according to the present invention is a side body structure of a vehicle which covers a door opening provided on a side of the vehicle so that the door can be opened and closed by a door.
A lock member for locking the door is provided at an upper side of the door opening, and a connection is made between the door opening provided with the lock member and a roof panel provided near the door opening. A reinforcing member is provided.

[0007] The lock member having the above structure can be set as a striker. According to the above configuration, the door opening corresponding to the lock member and the roof panel are connected by the reinforcing member, so that the rigidity of the locked portion of the door can be improved regardless of the size of the door opening. In particular, in the case of a center pillar-less vehicle, the amount of movement of the vehicle body or door into the vehicle interior at the time of a side collision can be suppressed.

In one embodiment of the present invention, the roof panel is provided with a roof reinforcement extending in the vehicle width direction, the reinforcing member is set as a reinforcing stay, and one end of the reinforcing stay is connected to the roof stay. It is connected to reinforcement.

[0009] The roof reinforcement having the above structure can form a closed cross section between the roof reinforcement and the roof panel. According to the above configuration, the door opening provided with the lock member and the roof reinforcement are connected by the reinforcing stay, so that the rigidity of the locked portion of the door can be further improved.

[0010] In one embodiment of the present invention, the door opening is provided with an annular door opening member along the door opening, and the door opening member is integrally continuous along the door opening. And an annular reinforcement extending annularly.

The door opening member having the above configuration includes a side outer panel including a roof side rail outer, a front pillar outer, a hinge pillar outer, a side sill outer, a rear pillar outer, and the like, a roof side rail inner,
A closed cross-sectional shape may be formed by a side inner panel including a front pillar inner, a hinge pillar inner, a side sill inner, a rear pillar inner, and the like.

According to the above construction, since the annular reinforcement is provided on the door opening member, the rigidity of the vehicle body and the torsional rigidity of the vehicle body can be improved, and the operability can be improved, and the lock member is provided. Since the above-mentioned annular reinforcement exists also in the portion, the rigidity of the lock portion can be further improved.

In one embodiment of the present invention, the door opening member is formed in a closed cross-section structure, and a knot-shaped reinforcing reinforcement is disposed in the closed cross section corresponding to the mounting position of the lock member. It is a thing.

According to the above construction, the rigidity at the position where the lock member is mounted is greatly improved by both the closed sectional structure of the door opening member and the node-shaped reinforcing reinforcement disposed in the closed sectional surface. In particular, in the case of a center pillar-less vehicle, the amount of movement of the vehicle body and the door into the vehicle interior at the time of a side collision can be further suppressed.

In one embodiment of the present invention, a front door is supported at the front side of the door opening via a hinge so as to be openable and closable. According to the above configuration, the above-described effect is particularly effective in the case where such a front door is provided, and since the annular reinforcement is present at the front side of the door opening, the support rigidity of the front door is improved. Can be achieved.

In one embodiment of the present invention, a rear door is supported at the rear side of the door opening via a hinge so as to be openable and closable. According to the above configuration, the above-described effect is particularly effective in the case where the rear door is provided, and the support rigidity of the rear door is improved because the annular reinforcement is present at the rear side of the door opening. be able to.

In one embodiment of the present invention, a rear end of the front door is locked to a front end of the rear door, and a front end of the rear door is locked to at least an upper side of the door opening. . According to the above configuration, since the door is locked at the high rigidity portion of the door opening, the support rigidity when the door is closed can be improved.

In one embodiment of the present invention, a reinforcing member extending in the vertical direction is disposed on the front vertical side of the rear door, and a lock unit provided on the reinforcing member is engaged with the lock member. Things.

According to the above configuration, by providing the above-described reinforcing member to the rear door, not only the rigidity of the rear door can be improved, but also the lock rigidity between the door and the vehicle body when the rear door is closed is improved, and To improve torsional rigidity,
Drivability can be improved.
