Description

  The present invention relates to a roof rail mounting structure in which a roof rail is mounted on a roof panel.

  There is a vehicle type in which a roof rail extending along the longitudinal direction of the vehicle body is attached to the roof portion at the top of the vehicle. The roof rail is a member for loading a load on the upper part of the vehicle and is also required to have a decorative property.

  The roof rail is attached to a highly rigid member to support the load of the load. Usually, the roof rail is often attached to the roof portion of the vehicle on the side body panel. About the said roof part, as disclosed by patent document 1, what is provided in the vehicle upper part of the part to which a side body outer panel and a side body inner panel are joined is known, for example. The roof portion in this example is disposed outside the roof panel in the vehicle width direction, and a roof rail is attached to the roof portion. Some roof rails are attached to a recess formed between the roof panel and the side body panel.

  The roof portion of the side body is required to have a storage space for the side curtain airbag, a structure space for dealing with a side collision, and the like due to an increase in safety performance requirements for occupant protection in the event of a collision. In addition, it is required to make the front pillar (A pillar) thin in order to ensure the design and visibility, and the roof part of the side body may have a thin design due to this.

  For this reason, depending on the type of vehicle, there is a vehicle width direction width in the vehicle upper portion of the roof portion that cannot sufficiently secure a width for attaching the roof rail. In such a case, it may be difficult to attach the roof rail to the roof portion.

  The present invention has been made in order to solve the above-described problems, and the object of the present invention is to provide a vehicle body structure in which it is difficult to attach a roof rail to an upper portion of a vehicle such as a side body inner panel constituting the roof portion. The object is to provide a roof rail mounting structure capable of suppressing the influence.

  In order to achieve the above object, in the roof rail mounting structure according to the present invention, a roof panel is disposed on the vehicle upper portion of the side body inner panel on the side of the vehicle, and the roof rail is mounted on the roof panel. In the roof rail mounting structure, a fixing bracket is disposed below the roof panel in the vehicle, and a protruding portion protruding above the vehicle is provided on the vehicle upper portion of the fixing bracket. The fixing bracket is connected to the roof rail while penetrating the roof panel, and the fixing bracket is connected to the side body in a state where the roof panel is disposed between the roof rail and the fixing bracket. It is joined to the inner panel.

  According to the present invention, the roof rail can be mounted on the roof panel in a stable state with securing mounting strength. As a result, even when the width in the vehicle width direction for attaching the roof rail cannot be secured on the vehicle upper portion of the side body inner panel or the side body outer panel, the roof rail can be attached to the vehicle upper portion. Therefore, it is possible to set the roof rail without lowering the degree of freedom in design such as incorporating the side curtain airbag mounting space and the collision response structure.

Next, as shown in FIG. 9B, the roof panel 30 is joined to the side body inner panel 50 or the like by welding. Further, the second bracket 22 is temporarily fixed to the first bracket 21. Here, the temporary fixing is a state in which the engagement portion 22g of the second bracket 22 is hooked to the hook portion 21g of the first bracket 21 and temporarily fixed.

  At this time, as shown in FIG. 3, the threaded portion of the rail connection bolt 24 welded to the second bracket 22 passes through the through hole 31 of the roof panel 30. After that, as shown in FIG. 10, the roof rail 10 is temporarily placed on the upper surface of the vehicle of the roof panel 30 with the rail connection bolts 24 passing through the mounting holes 12 a of the mounting base 12 of the roof rail 10.

  Then, it fastens with the washer 25a and the nut 25b. Finally, the bracket connection bolts 28 are passed through the bracket attachment holes 21e and 22e of the bracket joint surface portions 21d and 22d of the first bracket 21 and the second bracket 22, screwed into the welding nut 21h, and tightened. The second bracket 22 is fastened to the first bracket 21. Thereby, the attachment of the roof rail 10 to the roof panel 30 is completed.

  The description of the present embodiment is an example for explaining the present invention, and does not limit the invention described in the claims. Moreover, each part structure of this invention is not restricted to the said embodiment, A various deformation | transformation is possible within the technical scope as described in a claim.

  For example, the fixing bracket 20 may integrally form the first bracket 21 and the second bracket 22. Moreover, although the rail connection bolt 24 for attaching the roof rail 10 and the second bracket 22 are separate bodies, they may be integrated.

  In the present embodiment, the roof panel joint surface portion 22a of the second bracket 22 is joined to the vehicle lower surface of the roof panel 30, but the present invention is not limited to this. The roof panel joint surface portion 22a may be disposed at a distance from the vehicle lower surface of the roof panel 30. Even in this case, the load acting on the roof rail 10 can be received by the side body inner panel 50 via the fixing bracket 20.
