DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a roof side portion of an automobile for improving the rigidity of a roof side portion which moves from above a pillar portion to a roof panel.

[0002]

2. Description of the Related Art FIG. 13 shows a vehicle body structure of a cabin portion of a general automobile, in which a roof panel and a side body outer panel are removed. Car roof 10
The framework of No. 0 is a roof front inner rail 101,
The left and right roof side inner rails 102 and the roof back inner rail 103 are formed in a square shape.
A front pillar inner panel 104 is connected to a front end of the roof portion 100, and both sides of the roof portion 100
The center pillar inner panel 105 is connected.
The lower ends of the front pillar inner panel 104 and the center pillar inner panel 105 are connected to the floor panel 10.
6 are connected to side sill portions 107 provided on both sides. A center pillar reinforcement 108 is provided on the center pillar inner panel 105 to reinforce the pillar portion 109. A roof cross member 110 is provided in the roof portion 100 in a vehicle width direction corresponding to the left and right pillar portions 109, and the roof cross member 110 is attached to the left and right roof side inner rails 10.
2 are connected by welding.

By arranging the roof cross member 110 at the same position as the center pillar reinforcement 108 in this way, it is possible to suppress deformation of the cabin portion in response to a side impact. However, a sunroof vehicle having an opening for the sunroof 111 as shown by a broken line in the roof panel has a problem that the structure of this portion cannot be shared. Therefore, if the sunroof is reduced to a size that does not interfere with the roof cross member 110, the function as the sunroof is reduced by half.

[0004] Next, in FIG. 14, the roof cross member 110 is provided at a position shifted rearward from the left and right pillar portions 109 in order to share the vehicle body structure regardless of the presence or absence of the sunroof 111. It is.

[0005]

However, according to this structure, the rigidity between the left and right pillar portions 109 and the roof cross member 110 is low, and this portion buckles and deforms in response to an impact from the side. Therefore, there is a possibility that the pillar 109 may enter the cabin.

An object of the present invention is to solve the above-mentioned problems and to provide a structure of a roof side portion of an automobile which can improve the rigidity of a vehicle body and can share a vehicle body structure regardless of the presence or absence of a sunroof. And

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a structure of a roof side portion of a motor vehicle in which a roof cross member for reinforcing a roof panel is arranged behind a pillar portion on a vehicle body side. , A reinforcing member for connecting the pillar reinforcement for reinforcing the pillar portion and the roof cross member is provided on the roof side portion.

In the present invention, a pillar reinforcement for reinforcing a pillar portion and a roof cross member for reinforcing a roof panel are connected by a reinforcing member. The reinforcing member is provided on the roof side portion and transmits a load applied to the pillar reinforcement to the roof cross member. Thus, the deformation of the cabin portion due to the load applied to the pillar portion is prevented. The reinforcing member extends the front end portion forward of the joint portion with the pillar reinforcement to improve the rigidity of the roof side portion. The length of the reinforcing member can be set arbitrarily. The reinforcing member has an uneven cross section to improve rigidity. The connecting portion of the reinforcing member with the pillar reinforcement is formed in a U-shaped cross section so as to be combined with the pillar reinforcement. Since the joint is joined to the pillar reinforcement at the combination of the reinforcing members, the rigidity of the connection is improved.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings.

In FIG. 1 to FIG. 8, reference numeral 1 denotes an automobile body in which a vehicle body structure can be shared regardless of the presence or absence of a sunroof. The roof panel 2 has a case where a sunroof opening is formed and a case where a sunroof opening is not formed. Side body outer panels 3 are provided on both sides of the roof panel 2, and a front door 4 and a rear door 5 are provided. A center pillar (pillar portion) 6 is provided between the front door 4 and the rear door 5, and connects between a roof side rail 7 on the roof side and a side sill 9 on the floor panel 8 side. The center pillar 6 includes a center pillar inner panel 11 for connecting the roof side inner rail 10 and the side sill 9, a pillar reinforcement 12 for reinforcing the center pillar inner panel 11, and a side body outer panel 3 as a center pillar outer panel. I have.

A roof cross member 13 is provided between the left and right roof side inner rails 10 on the indoor side of the roof panel 2, and the roof cross member 13 provides a sun roof to the roof panel 2. In consideration of the provision thereof, the center pillar inner panel 11 is disposed so as to be shifted rearward of the vehicle body from the position thereof. 14 is a roof side inner rail 10 for reinforcing the roof side portion A.
Is a reinforcing member provided by welding or the like. The reinforcing member 14 connects the pillar reinforcement 12 and the roof cross member 13 to each other by spot welding or the like.

The reinforcing member 14 has a trapezoidal cross section 14a as shown in FIG.
The flange portion 12a provided at the upper end of the pillar reinforcement 12 is joined to the substantially middle position by spot welding (see FIG. 6). As shown in FIGS. 9 and 10, the shape of the reinforcing member 14 is
b, the pillar reinforcement 12
May be formed in a U-shaped section 14c as shown in FIGS.

According to the above configuration, since the pillar reinforcement 12 and the roof cross member 13 are connected to each other by the reinforcing member 14, the rigidity of the roof side inner rail 10 can be improved. Therefore, the load applied to the center pillar 6 on the side surface of the vehicle body can be received by the roof cross member 13 through the roof side inner rail 10 and the reinforcing member 14, so that the rigidity can be improved.

The present invention is not limited to the above-described embodiment. For example, the thickness, length, and cross-sectional shape of the reinforcing member 14 can be set arbitrarily.

[0015]

As described above, according to the structure of the roof side portion of the automobile according to the present invention, the following effects can be obtained. In a structure of a roof side portion of an automobile in which a roof cross member for reinforcing a roof panel is disposed behind a pillar portion on a vehicle body side surface, a pillar reinforcement for reinforcing the pillar portion is connected to the roof cross member. Since the reinforcing member is provided on the roof side portion, the rigidity of the roof side portion can be improved with respect to a load from the side surface. Therefore, the vehicle body structure can be shared regardless of the presence or absence of the sunroof, so that productivity and economic efficiency can be improved. In addition, since the front end of the reinforcing member extends forward of the joint with the pillar reinforcement, there is no possibility that the roof side portion of the front end of the reinforcing member is buckled by an impact from the side. Thus, the rigidity of the roof side portion can be improved. Furthermore, since the cross section of the reinforcing member is made uneven, the strength of the reinforcing member can be increased, and the rigidity of the roof side portion can be improved. Furthermore, since the connecting portion of the reinforcing member with the pillar reinforcement is formed in a U-shaped cross section, the number of spot welding points at the connecting portion with the pillar reinforcement can be increased, and the torsional rigidity of the vehicle body is reduced. Can be improved.
