  If the rigidity of the guide frame is insufficient, bending and vibration of the frame will increase, and vibration will be transmitted to the sunroof panel and unpleasant vibration noise will easily occur. Although the rigidity is increased by integrally forming the guide rail part, the insertion groove and the drainage groove as in the structure of Patent Document 1 and Patent Document 2, it cannot be dealt with when suddenly a large load is applied. Is also possible. For example, a thicker frame material or a separate reinforcing member may be used as a structure to increase rigidity, but the former increases the size and weight of the frame, and the latter increases the number of parts. It is easy to invite the problem of an increase in the number of assembling steps accompanying an increase in the number of steps.

  The present invention has been created to solve the above problems, and provides a structure of a guide frame in a sunroof device in which the rigidity of the guide frame is effectively increased and the vibration of the sunroof panel is suppressed. The purpose is that.

In order to solve the above-described problems, the present invention provides a sunroof panel that is attached to an opening of a fixed roof, and is connected to the sunroof panel, and is slid in the front-rear direction of the vehicle by a drive source to move the sunroof panel in the front-rear direction of the vehicle A drive slider to be moved, a guide rail portion formed along the longitudinal direction of the vehicle for guiding the slide of the drive slider, and a drainage groove formed along the guide rail portion outside the guide rail portion in the vehicle width direction. Yes and, further, has an upper surface portion extending from the upper edge in the vehicle width direction outer side of the partition wall of the drainage grooves in horizontally outward in the vehicle width direction, the vehicle width direction outside portion of the upper surface portion It extends in the same plane to form a mounting flange portion fixed to a frame located above each bottom surface of the lower and the guide rail and the drainage grooves of the fixed roof Gaidofu In sunroof apparatus provided with over arm, the said guide frame is formed at the lateral position of the drainage grooves separating the partition wall portion, a hollow closed cross-section portion is integrally continuous along at least a partially culvert The hollow closed cross-sectional portion has a structure in which an upper portion is closed by the upper surface portion and a lower portion is closed by a bottom plate portion that is flush with the bottom surfaces of the guide rail portion and the drainage groove .

  According to this structure, by having the closed cross-sectional structure, the rigidity of the guide frame is increased, and the vibration of the sunroof panel due to the bending of the frame when a large load is generated is prevented. Compared with the method of ensuring rigidity by increasing the thickness of the guide frame, the size and weight of the device can be prevented, and the problem of increased assembly man-hours can be solved by forming the hollow closed cross-section part integrally. . And the increase in the height dimension of an apparatus can be suppressed by forming a hollow closed section in the position next to a drainage ditch.

And according to the said structure, since the rigidity around the coupling | bond part with the vehicle body in a guide frame becomes especially strong, the bending of a flame | frame becomes difficult to generate | occur | produce more and the vibration prevention effect of a sunroof panel increases further.

  A front frame extending in the vehicle width direction is connected to the front end portion of the guide frame, and the guide rail portion is mounted on the front frame via a bracket and fixedly supported. The structure.

  According to this structure, in addition to the effect of the hollow closed cross section, the rigidity of the guide frame is further increased, and the vibration prevention effect of the sunroof panel is enhanced.

  According to the present invention, the rigidity of the guide frame can be increased without causing problems such as an increase in the size of the apparatus, an increase in weight, and an increase in assembly man-hours.

  When the rear slider 21 slides further rearward, the front slider 20 is interlocked with the rear slider 21 by the panel support stay 31, that is, the engaging pin 31 a presses the cam groove 20 a rearward. As shown in (c), the sunroof panel 4 moves rearward while being tilted up.

  As shown in FIGS. 2 and 8 (a cross-sectional explanatory view of the guide frame as viewed from the direction E in FIG. 1), the present invention has a position next to the drainage groove 10 in the guide frame 5, that is, in this embodiment, drainage. The main feature is that a hollow closed cross-section 22 which is continuous at least partially along the drainage groove 10 is integrally formed at a position beside the groove 10. In the present embodiment, the guide frame 5 is partitioned into a guide rail portion 9 and a drainage groove 10 by a first partition wall portion 5B that rises vertically from a flat bottom plate portion 5A along the front-rear direction of the vehicle. The drainage groove 10 and the hollow closed cross-section portion 22 are partitioned by a second partition wall portion 5C that rises in an inclined manner from the bottom plate portion 5A along the front-rear direction of the vehicle, outside the partition wall portion 5B in the vehicle width direction. That is, each of the guide rail portion 9, the drainage groove 10, and the hollow closed cross-section portion 22 is formed as a bottom plate portion 5A having the same bottom surface. Each of the guide rail portion 9 and the drainage groove 10 is formed as a space whose upper side is open.

  The guide frame 5 has an upper surface portion 5F that extends horizontally from the upper end of the second partition wall portion 5C toward the outside in the vehicle width direction. At least a part of the upper surface portion 5F is further extended in the same plane toward the outer side in the vehicle width direction to constitute the mounting flange portion 5E. The mounting flange portion 5E is in contact with the ceiling frame 23 of the vehicle body located below the fixed roof 2, and becomes a portion fixed to the ceiling frame 23 by fastening means using screws or the like. The hollow closed cross-section portion 22 is formed so as to be continuous with at least the lower surface of the mounting flange portion 5E in the cross-sectional view as seen from the front-rear direction of the vehicle as shown in FIG. 8, and is continuous with the lower surface of the mounting flange portion 5E. The closed cross section is surrounded by the upper surface portion 5F, the outer wall portion 5D formed substantially vertically between the bottom plate portion 5A and the upper surface portion 5F, the bottom plate portion 5A, and the second partition wall portion 5C. To form.

  In the present embodiment, the upper surface portion 5F and the mounting flange portion 5E are locally formed with respect to the entire length of the guide frame 5 as shown in FIG. The part 5F is formed on the front side, and the attachment flange part 5E is formed on the front and rear ends of the upper surface part 5F). In some cases, it may be formed over the entire length of the guide frame 5.

  As described above, in the guide frame 5, if the hollow closed cross-section portion 22 that is continuous at least partially along the drain groove 10 is integrally formed at a position beside the drain groove 10, the closed cross-section structure is obtained. As a result, the rigidity of the guide frame 5, in particular the torsional rigidity, is improved, and the vibration of the sunroof panel 4 due to the bending or vibration of the frame when a load is generated is prevented. Compared with the method of ensuring the rigidity by increasing the thickness of the guide frame 5, there is no problem of increasing the size and weight of the device, and the assembly man-hour is not increased by integrally forming the hollow closed cross section. As described above, when the guide frame 5 is made of an aluminum alloy mold, the hollow closed cross-section portion 22 can be easily formed integrally. In addition, the problem of the height of the device is extremely important for a sunroof device disposed in a narrow space that is restricted in the height direction of the roof of the vehicle, and in this respect, the hollow closed cross section as in the present invention. By forming the portion 22 at a position next to the drainage groove 10, an increase in the height dimension of the apparatus can be suppressed.

  In addition, if the hollow closed cross-section portion 22 is formed continuously at least on the lower surface of the mounting flange portion 5E for fixing the guide frame 5 to the vehicle body, in particular, around the portion where the guide frame 5 is connected to the vehicle body. Since the rigidity is improved, the frame is less likely to be bent, and the vibration prevention effect of the sunroof panel 4 is further enhanced.

  Furthermore, if the guide rail portion 9 is configured to be mounted and fixedly supported on the front frame 6 via the bracket 15, the rigidity around the front end of the guide frame 5 is increased, and thus the hollow closed cross-section portion 22. In addition to the effect of improving the rigidity, the effect of preventing the vibration of the sunroof panel 4 is further enhanced.

  The preferred embodiments of the present invention have been described above. In FIG. 1, the formation range of the hollow closed cross-section portion 22 is extended between the front and rear mounting flange portions 5E. However, if a predetermined rigidity is obtained, for example, the hollow closed cross-section portion 22 may be formed only in the vicinity of the mounting flange portion 5E. . In addition, the layout, shape, number, and the like of each component are not limited to those described in the drawings, and design changes can be made as appropriate without departing from the scope of the invention.
