Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an upper body structure of a vehicle, and particularly to a reinforcing structure when an outer sliding sunroof structure is installed.

(Prior Art) In recent years, vehicles have increasingly adopted a sunroof structure in which the roof of the vehicle body can be opened, and there is also a trend toward larger structures that increase the open area. As an example, as disclosed in Japanese Utility Model Application No. 56-97117, there is a sunroof that opens and closes an opening provided in the vehicle roof, and a sunroof that is arranged in the front and back direction on both sides of the opening, and A pair of left and right first guide rails slidably support the front part of the sunroof via rollers, and a pair of first guide rails are arranged in the front-rear direction on the upper surface of the roof panel behind the opening, and support the rear part of the sunroof via rollers. and a pair of left and right second guide rails that are slidably supported by the sunroof, and the sunroof is guided by the first and second guide rails to close the opening flush with the outer surface of the roof (roof panel). An outer slide type is known in which the roof can be opened and closed between a closed position and an open position located behind the opening and outside the outer surface of the roof.

(Problem to be solved by the invention) However, in this case, the second guide rail provided on the top surface of the roof panel behind the opening is
Since the sunroof is supported only by the tension and rigidity of the roof panel, the sunroof tends to bend due to the weight of the sunroof when it is opened or closed, and there is a risk that smooth opening and closing may not be possible.

The present invention has been made in view of the above, and its purpose is to appropriately reinforce the portion of the roof panel that supports the guide rail with reinforcement to increase the supporting rigidity of the guide rail, and to improve the support for the sunroof. In addition to ensuring smooth opening and closing of the reinforcement, the reinforcement can be easily installed and the appearance can be improved.

(Means for solving the problem) In order to achieve the above object, the solution of the present invention has a pair of left and right channel-shaped channels extending in the front and back direction on the top surface of the roof panel behind the opening provided in the vehicle roof. In an upper body structure of a vehicle in which a guide rail is provided and a sunroof that opens and closes the opening is guided by the guide rail,
The configuration is as follows.

That is, a pair of left and right recesses are formed in the roof panel to accommodate the respective guide rails, while a pair of left and right recesses are formed on the lower surface of the roof panel behind the opening to connect the two recesses in the roof panel, and to connect the recesses in the roof panel. A reinforcement forming a closed cross section is provided. The guide rail and the reinforcement are attached to the recess by being fastened together with a fastening member while sandwiching the bottom surface of the recess.

(Function) With the above configuration, in the present invention, the pair of left and right recesses that respectively house and attach and support the pair of left and right guide rails behind the opening of the roof panel are each formed in a channel shape, thereby creating a so-called bead effect. In addition, since the roof panel and the roof panel are connected and reinforced by the reinforcement that forms a closed cross section, the support rigidity of the guide rail is greatly increased.
This makes it possible to sufficiently resist the weight of the sunroof that is applied when the sunroof is opened and closed, and the roof panel or guide rail does not bend.

Furthermore, the guide rail and the reinforcement can be attached to the recess by tightening them together with a fastening member while sandwiching the bottom surface of the recess, so that these can be easily installed with a small number of parts. It can be carried out. Further, the guide rail is housed in the recess, and the reinforcement mounting member (i.e., the fastening member) is also provided in the recess, and these are not exposed to the outside and are not noticeable, so the appearance is good. Become something.
