[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a frame structure of a sunroof that is attached to a sunroof opening formed in a vehicle roof.
[0002]
[Prior art]
In a vehicle sunroof, a frame structure is attached to a sunroof opening formed in a vehicle roof, and the opening is opened and closed by moving the roof panel along a pair of side frame members constituting the frame structure. Is done.
[0003]
In addition to the pair of side frame members, the conventional frame structure includes a horizontal frame member that connects the front end portions or the rear end portions of the pair of side frame members.
[0004]
The pair of side frame members are arranged along the vehicle longitudinal direction side edge of the sunroof opening formed in the vehicle roof, and a sunroof driving guide rail on which a mechanical unit that drives the roof panel is slid A rain rail portion (drainage groove) is formed along the longitudinal direction.
[0005]
A rain rail part is formed in the longitudinal direction of the horizontal frame member. Some horizontal frame members are integrally formed with a sunroof driving cable path so as to block the rain rail portion. The cable path passes through the lower surface of the rain rail portion of the horizontal frame member, is bent upward, and is guided to each side frame.
[0006]
The horizontal frame member is connected to the lower side of the side frame member with a step so that the water accumulated in the rain rail portion of the horizontal frame member does not flow into the sunroof driving guide rail of the side frame member. Yes. In addition, the rain rail portions of the side frame member and the lateral frame member are connected to a drain pipe at a predetermined position, and water accumulated in each rain rail portion is drained from the drain pipe to the outside of the vehicle.
[0007]
[Problems to be solved by the invention]
However, the frame structure of the conventional sunroof has a step between the rain rail portion of the horizontal frame member and the sunroof driving guide rail of the side frame member. There was a drawback that a step was formed in the rail portion in the same manner, and the water accumulated in the step portion could not be smoothly flowed to the drain pipe.
[0008]
In addition, in order to smoothly flow the water accumulated in the stepped portion, if it is configured with a member having an inclined surface between the rain rail portion of the horizontal frame member and the rain rail portion of the sunroof, the rain rail portion of the horizontal frame member has a large size. Since cutting is necessary, there is a problem that the rigidity of the frame itself is weakened.
[0009]
Further, in the case where the sunroof driving cable path described above is formed integrally with the horizontal frame member, the path blocks the part of the water flow, so that the water accumulated in the rain rail portion of the horizontal frame member is blocked. As a result, there is a problem that there is a case where the air leaks to the sunroof driving guide rail of the side frame member or the indoor side.
[0010]
The present invention has been made in view of such circumstances, and smoothly drains the water accumulated in the stepped portion without reducing the strength of the frame member and the water blocked by the sunroof driving cable path. It is an object to provide a sunroof frame structure that can be guided to
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is arranged along the vehicle longitudinal direction side edge of the sunroof opening formed in the vehicle roof, and the sunroof driving guide rail and the first rail in the longitudinal direction thereof. A pair of side frame members formed with drainage grooves and a pair of side frame members disposed along the vehicle body width direction are connected to each other, and a second drainage groove is formed in the longitudinal direction thereof. And a frame structure of a sunroof having a sunroof driving cable path formed so as to block the second drainage groove, the side frame member of the horizontal frame member And a third drainage groove that is inclined toward the first drainage groove of the side frame member, and the third drainage groove of the first drainage groove of the side frame member and An opening is formed at the intersection, and the sunroof driving cable path is formed with a communication hole that communicates the second drainage groove and the third drainage groove. The groove and the first drainage groove of the side frame member are communicated with each other through the communication hole, the third drainage groove, and the opening.
[0012]
According to the first aspect of the present invention, the second drainage groove of the horizontal frame member is disposed with a step below the sunroof driving guide rail in order to prevent water from flowing into the sunroof driving guide rail. In the connecting portion between the horizontal frame member and the side frame member, a third drainage groove that gently slopes from the lower surface of the second drainage groove of the horizontal frame member to the vicinity of the first drainage groove of the side frame member is formed. And it was set as the structure which formed the opening part in the 1st drainage groove so that water could flow continuously between the 3rd drainage groove and the 1st drainage groove. As a result, water smoothly flows between the second drainage groove of the lateral frame member and the first drainage groove of the side frame member, so that water does not overflow from each drainage groove, and the side frame member Since no deep notch is required, rigidity as a frame can be secured.
[0013]
Further, according to the present invention, since the communication hole for communicating the second drainage groove and the third drainage groove is formed in the sunroof driving cable path, water is blocked by the sunroof driving cable path. The water can be smoothly guided to the drain pipe. In addition, regardless of the angle of the frame structure (vehicle body), the water in each drainage groove can be reliably guided to the drain pipe. Further, since it is not necessary to bend the cable path for driving the sunroof abruptly, it is advantageous for reducing the sliding resistance and wearing of the cable guiding portion. When the cable guiding portion and the horizontal frame member have a resin integrated structure, the number of parts and cost can be reduced. In addition, since the number of parts that require a seal member for preventing water leakage is reduced, there is no need to worry about water leakage.
