Description

The technology disclosed in this specification relates to vehicles.

Patent Document 1 discloses a vehicle having a movable sunroof. A sunroof is composed of an opening provided in a roof panel and a movable panel that opens and closes the opening. The opening is opened and closed by sliding the movable panel relative to the roof panel. In this vehicle, a slide mechanism for sliding the movable panel is attached to the roof panel together with the movable panel.

JP 2010-188797 A

In a vehicle having a movable sunroof, a frame is provided on the roof so as to surround the opening. Since the roof panel is reinforced by the frame, the heavy sliding mechanism can be adequately supported by the roof panel. In addition, by reinforcing the roof panel with the frame, the vibration of the roof panel is suppressed, and the generation of noise (that is, vibration sound) is suppressed.

There are vehicles that have a transparent roof panel that spans between a pair of roof side rails and is fixed to the roof side rails. A metal roof panel is provided behind the transparent roof panel. Since this type of vehicle does not have a sliding mechanism for sliding the transparent roof panel, it is not necessary to provide the roof with a frame for supporting the sliding mechanism. By not providing a frame on the roof, the structure of the roof can be simplified and the weight of the vehicle can be reduced. On the other hand, since the roof is not provided with a frame, the metal roof panel arranged behind and adjacent to the transparent roof panel is likely to vibrate and generate noise. This specification proposes a technique for suppressing vibration of a metal panel in a vehicle having a transparent roof panel fixed to roof side rails and a metal panel arranged behind the transparent roof panel.

A vehicle disclosed herein has a first roof side rail, a second roof side rail, a transparent roof panel, a metal roof panel, a reinforcement and a bracket. The first roof side rail extends along the front-rear direction. The second roof side rail extends along the front-rear direction and is spaced apart from the first roof side rail. The transparent roof panel is installed between the first roof side rail and the second roof side rail and fixed to the first roof side rail and the second roof side rail. The metal roof panel is arranged behind the transparent roof panel and spans between the first roof side rail and the second roof side rail. The reinforcement extends along the width direction of the vehicle, spans between the first roof side rail and the second roof side rail, and is fixed to the lower surface of the metal roof panel. The bracket extends from the lower surface of the reinforcement to an inner surface of the first roof side rail facing the cabin side of the vehicle, is fixed to the lower surface of the reinforcement, and is fixed to the first roof side. Affixed to said inner surface of the rail.

In this vehicle, a reinforcement is provided on the lower surface of the metal roof panel, and the reinforcement is fixed to the first roof side rail via brackets. That is, the metal roof panel is reinforced by reinforcements and brackets. Therefore, the metal roof panel is less likely to vibrate, and noise can be suppressed.
