Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a frame structure of a sunroof in which an openable / closable slide panel is provided in an opening of a fixed roof.
[0002]
[Prior art]
In the sunroof device, a guide groove for sliding the slider provided on the slide panel, an insertion groove for inserting the drive push-pull cable, and a side drainage groove for discharging rainwater to the outside, Recently, the adoption of a so-called frameless structure in which aluminum alloy materials are formed into a common member by extrusion molding and directly attached to a fixed roof tends to be actively promoted recently.
[0003]
In the case of this structure, the extruded material is extended to both sides of the opening provided in the fixed roof so that the side frame member is also used, and the front ends of the left and right side frame members are provided with front drainage grooves. By connecting each other with the front frame member, the drainage grooves of the side frame member and the front frame member are made continuous so as to form a substantially U shape in a plan view.
[0004]
[Problems to be solved by the invention]
However, in the extruded material, the cross-sectional shape orthogonal to the longitudinal axis is uniform over the entire length, and all of the guide groove, the insertion groove, and the drainage groove are opened at the cut end face. Here, the side drainage groove must rather be opened toward the connecting part with the front frame member in order to make the left and right communicate, but if the guide groove and the insertion groove are open, the water is submerged from there. Does not necessarily induce malfunction.
[0005]
In order to prevent water intrusion into the guide groove and insertion groove, these should be provided at a higher position than the side drainage grooves. However, the height of the frameless structure is one of the advantages of reducing the frame accommodation space. It is not a good idea to provide such a height difference that causes an increase in dimensions.
[0006]
The present invention has been devised in order to cope with such problems, and its main purpose is made of an extruded material and other than the drainage groove without increasing the height dimension of the housing space of the frame. It is an object of the present invention to provide a sunroof frame structure improved so as to prevent water intrusion into the portion.
[0007]
[Means for Solving the Problems]
In order to achieve such an object, the present invention has a sunroof frame structure in which an openable / closable slide panel 3 is provided in the opening 2 of the fixed roof 1, and includes a push-pull cable insertion groove 9 and a slide panel guide groove 10. The front ends of the pair of left and right side frame members 4 integrally formed with the side drain grooves 11 are connected by the front frame member 5 having the front drain grooves 15 and the upper surface of the side frame member. And a shielding member 21 that covers a portion excluding the side drainage groove on the front end surface of the side frame member from the inner side of the inner circumferential edge of the opening, and the shielding member is an inner circumferential edge of the opening on the upper surface of the shielding member. Only the inner part of the inner wall has a water-impervious wall 23 erected so as to be along a predetermined gap from the inner peripheral edge . If it does in this way, the flooding from the push pull cable insertion groove and the slide panel guide groove is prevented by the shielding member.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the configuration of the present invention will be described in detail with reference to a specific embodiment shown in the accompanying drawings.
[0009]
FIG. 1 shows a fixed roof of an automobile provided with an outer slide type sunroof device to which the present invention is applied. The fixed roof 1 is formed with a generally rectangular opening 2 having a long side in the vehicle body width direction, and the opening 2 is a slide panel 3 made of plate glass or the like that is movable above the fixed roof 1 (in FIG. 1). It can be opened and closed freely.
[0010]
Inside the fixed roof 1, as shown in FIG. 2, a pair of left and right side frame members 4 extending in the front-rear direction along the left and right side edges of the opening 2, and along the front edge of the opening 2. The front frame member 5 extending in the left-right direction is attached in a state of being coupled to each other so as to form a substantially U shape in a plan view. Between the rear ends of the left and right side frame members 4, there is provided a motor 7 with a speed reducer that pushes and pulls the push-pull cable 6 to open and close the slide panel 3.
[0011]
The side frame member 4 and the front frame member 5 are fixed at appropriate positions to a stiffener (not shown) provided on the inner surface of the fixed roof 1 by screwing or the like. The motor 7 with a speed reducer is also fixed to the fixed roof 1 via a mounting bracket 8 fixed to the inner surface of the fixed roof 1 with screws.
[0012]
The side frame member 4 is formed by extrusion molding of an aluminum alloy material, and as shown in detail in FIG. 3, the push-pull has a C-shaped cross section that is open toward the outside of the vehicle body so that the push-pull cable 6 can be inserted. A slide having a U-shaped cross section in which the center of the vehicle body (the side facing the push-pull cable insertion groove) is opened so that the cable insertion groove 9 and a slider (not shown) attached to the lower surface of the slide panel 3 are slid together. A panel guide groove 10, a side drainage groove 11 having a U-shaped cross section with the upper side open, and a joint flange 12 to the fixed roof 1 protruding in a horizontal direction from a side wall outside the vehicle body of the side drainage groove 11, However, they are integrally formed with a constant cross section arranged in parallel from the center side of the vehicle body.
[0013]
The side drainage groove 11 receives rainwater dropped from the left and right side edges of the opening 2 and guides it to the front and rear of the vehicle body. The rainwater guided rearward is attached to the rear end of the side frame member 4. The discharged drainage member 13 and the drain tube 14 disposed in the rear pillar of the vehicle body are discharged to the outside of the vehicle. Further, the rainwater guided to the front side, along with rainwater dropped from the front edge of the opening 2 into the front drainage groove 15 formed in the front frame member 5 made of a press-formed product of a steel plate, It is discharged out of the vehicle through a connecting member 16 provided in the section and a drain tube 17 disposed in the front pillar of the vehicle body.
[0014]
A rear drain groove member 18 formed in a U-shaped cross-section whose upper side is opened by press forming of a steel plate extends in the vehicle width direction below the rear edge of the opening 2 (see FIG. 2). The rear drainage groove member 18 is aligned with the position of both side ends on the center line in the width direction of the side drainage groove 11 and receives rainwater dripped from the rear edge of the opening 2 to the left and right side drainage grooves 11. It comes to lead.
[0015]
The front end of the side frame member 4 is partially cut away from the side drainage groove 11 and the joining flange 12 that follows, and is shielded by the remaining push-pull cable insertion groove 9 and slide panel guide groove 10. A member 21 is attached. The shielding member 21 is formed of, for example, a synthetic resin material, and as illustrated in FIGS. 4 and 5, the front wall that blocks the open end surface other than the side drainage groove 11 at the front end of the side frame member 4. 22, and a water shielding wall 23 raised along the inner peripheral edge of the opening 2 at a position slightly inside the inner peripheral contour of the corner of the opening 2, and the space between the water shielding wall 23 and the front wall 22 is blocked. An upper wall 24 is provided, and the front end of the side frame member 4 is wrapped around. By this shielding member 21, the front portion opening surface of the push-pull cable insertion groove 9 and the slide panel guide groove 10, and the front portion from the portion located slightly inside the corner portion of the opening on the upper surface of the front end portion of the side frame member 4. Is closed.
[0016]
By providing this shielding member 21, only the side drainage grooves 11 of the side frame member 4 are open toward the front drainage grooves 15 of the front frame member 5, and rainwater that has flowed through the side drainage grooves 11. The rainwater that flows into the front drainage groove 15 and falls from the corner portion of the opening 2 is regulated by the water shielding wall 23 and the upper wall 24 of the shielding member 21, and also flows down into the front drainage groove 15. Also, it is discharged out of the vehicle through the drain tube 17 connected to the connecting member 16 fixed to the side end of the front frame member 5.
[0017]
【The invention's effect】
As described above, according to the present invention, the water collected in the drainage groove of the front frame member can be prevented from flowing back into the slide panel guide groove and the push-pull cable insertion groove of the side frame member. It is possible to prevent water drops falling from the corner portion on the front edge side from entering from the upper surface of the side frame member and drain the water into the drainage groove of the front frame member. Accordingly, the push-pull cable insertion groove, the slide panel guide groove, and the side drainage groove can be integrally formed at the same level, thereby simplifying the structure of the sunroof frame and reducing the height of the housing space of the frame. A big effect can be demonstrated.
