Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement in a sunroof opening / closing structure for an automobile.

[Prior Art] Conventionally, in a vehicle of this type, in particular, a so-called sunroof vehicle in which a sunroof is openably provided on a roof portion of a vehicle body, as disclosed in, for example, Japanese Utility Model Laid-Open No. 59-312,
There is a structure in which the lid is guided and slid along a pair of left and right guide rails via rollers.

[Problems to be solved by the invention] However, in such a conventional structure, since the lid is largely twisted due to lateral deflection, the roller is likely to be twisted or fluttered, and moreover, the pair of left and right guide rails are accurate. If they are not installed parallel to each other, the sliding resistance between the roller and the guide rail will be large, and the lid will not open and close smoothly. There was a problem of poor sex.

The present invention has been made under the above circumstances, and its purpose is to reliably prevent twisting of the lid and fluttering between the guide roller and the guide rail. It is to provide an opening and closing structure.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention covers a roof opening of a roof panel of a vehicle body roof from the outside with a lid that extends in the vehicle width direction. The front and rear ends of the lid are supported by brackets that engage with guide rails having a U-shaped cross section through rollers, and the roof opening can be opened and closed by sliding the lid toward the rear of the vehicle through drive means. In a sunroof opening / closing structure for automobiles, a cushion ring made of an elastic body is provided coaxially with the roller shaft on the roller mounting surface of the bracket, and a stopper is provided at a position corresponding to the facing position of the cushion ring with the guide rail. The stopper is provided and is elastically brought into contact with the guide rail. In this case, the stopper is provided. Is preferably made of a slippery material such as a fluororesin.

[Operation] That is, according to the present invention, by adopting the above configuration, a cushion ring made of an elastic body is provided on the roller mounting surface of the bracket corresponding to the position facing the guide rail, and the cushion ring and the guide rail Since the stopper is provided at a position corresponding to the facing position, and the stopper is elastically brought into contact with the guide rail, the vertical load of the lid is received by the roller, and further, the stopper of the cushion ring is provided on the left and right sides of the lid. Since the load and torsional load are received, twisting of the lid and fluttering due to twisting of the lid are reduced, and sliding resistance can be reduced even if the guide rails are not accurately parallel to each other. The generation of sound is reliably prevented.

[Embodiment] The present invention will be described in detail below with reference to an embodiment shown in the drawings.

As shown in FIG. 1, reference numeral 1 in the figure denotes a vehicle body roof portion of an automobile according to the present invention. The roof panel 2 of the vehicle body roof portion 1 has a roof opening portion 3 which is wide open substantially in the width direction of the vehicle body. On the upper surface of the roof panel 2 behind the roof opening portion 3, a pair of left and right roof openings is provided. Rear guide rails 4 are laid parallel to each other along the front-rear direction of the vehicle body. A lid 5 is provided on the slide rail 4 so as to be guided and slidable via a driving means described later. The lid 5 extends in the vehicle width direction so as to completely cover the upper surface of the roof opening 3 from the outside. The roof panel 2 is disposed so as to straddle the roof panel 2 and is kept flush with the roof panel 2 when the door is closed. When the door is opened, the roof panel 2 is guided upward so that the roof panel 2 and the roof panel 2 are overlapped with each other. The opening 3 can be opened and closed.

At the front end of the lid 5, as shown in FIGS. 2 and 3, a stay 6 and a bracket 8 having a substantially triangular shape pivotally supported by the stay 6 via a pin 7 are provided. A pair of guide rollers 9 and 9 are attached to the front and rear portions of the lower side of the bracket 8. The guide rollers 9 and 9 are attached to the bracket 8 by caulking as shown in FIG. A resin layer 92 made of ABS or the like, a rubber layer 93, and a slippery sheet layer made of a fluorine-based resin or the like are formed around the roller shaft 91.
It has a three-layer structure in which 94 are sequentially laminated, and this sheet layer 94 is
The roller is additionally provided so as to be wound up to the side surface, and is rollably engaged along a front guide rail 10 laid on the inner surface of the vehicle body and having a U-shaped cross section. Further, one end of a driving link 11 as a driving means is connected to the bracket 8, and an end portion of the driving link 11 is
The lid 5 is connected to a drive shoe 12 that slides along the front rail 10. The drive shoe 12 is moved in the front-rear direction by a drive motor (not shown) via a drive wire 13 to open / close the lid 5. It is something like this.

Further, in the figure, 14 and 14 are cushion rings made of a rubber elastic body provided on the roller mounting surface of the bracket 8.
The cushion ring 14 is mounted coaxially with the roller shaft 91 of the guide roller 9 and, as shown in FIGS. 4 and 5, at a vertical position corresponding to the position facing the front guide rail 10. Stoppers 15 and 15 made of a slippery material such as fluorine resin are provided.
When the bracket 8 tries to move outward (left side in FIG. 5), the outer surfaces 10 of the guide rails 15 and 15 are
When the bracket 8 tries to move inward (to the right in FIG. 5) while elastically abutting against a, the side surface of the guide roller 9 elastically moves to the inner side surface 10b of the guide rail 10. By abutting on each other to regulate the movement, the lateral load and the twisting load of the lid 5 are shared and received. Also, in the figure, 17 the lid 5
A bracket that supports the rear end of the rear guide rail 4 is slidably engaged with the rear guide rail 4.

In the figure, reference numeral 30 denotes a sunshade arranged inside the lid 5, which slides along a guide rail 101 attached to the front guide rail 10 via a support bracket 31 so that the sunshade is similar to the lid 5. The roof opening 3 is provided so as to be slidable toward the rear so that the roof opening 3 can be opened and closed. The sunshade 30 is selectively driven by a driving mechanism of the lid 5 via a locking mechanism 32 that is remotely operated. As shown in FIG. 2, the locking mechanism 32 can be driven to open and close in an interlocking manner, and is rotatably urged in one direction by the urging force of a return spring (not shown) on the support bracket 31. A hook member 33 pivotally supported on the hook member 33, and a handle 36 for remotely moving the hook member 33 through a cable 34 and a rotating lever 35 against the biasing force of the return spring (not shown). Together are constituted by rotational operation to secure the handle 36 to the lower surface side of the shade 30, thereby rotating the hook member 33 upward, drive shoe 12 constituting the driving means of the lid 5
The engaging pin 37 provided on the can be engaged and disengaged.

That is, when the lid 5 is completely closed, the locking mechanism 32 causes the drive shoe 12 to slide by the drive of a drive motor (not shown) to start the sun shade 30 simultaneously with the opening operation of the lid 5 to start the roof opening. 3 is opened, and operates similarly when the lid 5 is closed from the opened state. At this time, when the lid 5 and the sunshade 30 are in the door-opened state and only the lid 5 is closed, the handle 36 is rotated to rotate the hook member 33 upward so that the locking pin of the drive shoe 12 is locked. This is performed by operating a drive motor (not shown) in a state where the locked state with 37 is released. Furthermore, when the lid 5 and the sunshade 30 are closed, and when only the sunshade 30 is manually opened, the hook member 33 is rotated by rotating the handle 36.
Is rotated upward to release the engagement state of the drive shoe 12 with the engagement pin 37.

[Effects of the Invention] As is apparent from the above description, according to the present invention, the roof opening of the roof panel of the vehicle body roof portion is covered from the outside with a lid that extends across the vehicle body width direction. The front and rear ends are supported by brackets that engage with guide rails having a U-shaped cross-section through rollers, and the lid is guided and slid toward the rear of the vehicle body through drive means so that the roof opening can be opened and closed. In a sunroof opening / closing structure for an automobile, a cushion ring made of an elastic body is provided coaxially with the roller shaft on the roller mounting surface of the bracket, and a stopper is provided at a position corresponding to the facing position of the cushion ring with the guide rail. ,
Since the stopper is configured to elastically abut the guide rail, the vertical load of the lid can be received by the roller, and the lateral load and the torsion load of the lid can be received by the stopper of the cushion ring. Therefore, twisting of the roller and fluttering due to twisting of the lid can be reduced.

Also, even if the guide rails are not accurately parallel to the left and right, the stopper of the cushion ring can reduce sliding resistance and can reliably prevent the generation of abnormal noise. Is played.
