Description

[Detailed Description of the Invention] The present invention relates to a sliding roof opening/closing device for a vehicle, and is mainly concerned with a sliding roof opening/closing device for a vehicle. an opening/closing mechanism that supports the front part of the panel in a cantilevered state when the panel is opened; This relates to a slide show of a sliding roof opening/closing device for a vehicle, in which a slide show connected thereto slides on a guide rail within an opening.

Conventionally, a slide show in a sliding roof opening/closing device for a vehicle is provided at the lower end of an opening/closing mechanism for opening/closing a panel, and serves to support and move the panel. In order to prevent vibration, chatter, and rattling when the panel is moved or raised and lowered, a slide show has been used that has elasticity and uses this elasticity to absorb vibrations and the like. but,
This conventional slide show is effective when used on vehicle sliding roofs where the panel is stored below the vehicle roof surface and does not receive wind resistance when the opening is opened. When the panel is used on a sliding roof for a vehicle located above the vehicle roof surface, when the opening is opened while the vehicle is running, the panel will be subject to wind pressure corresponding to the speed of the vehicle, causing the panel to The force exerted on the cantilevered slide show is enormous. At this time, if the slide show has elasticity, this stress will compress the slide show and create a gap between it and the guide rail.As a result, the panel cannot be held in a stable state, so the panel This will cause backlash and vibration, and this will cause the panel backlash and vibration mentioned above.
This had the opposite effect in terms of vibration prevention. Therefore, it was considered that the slide show had a simple shape and had a strong or rigid shape with almost no elasticity, but this slide show
When sliding on the guide rail, the sliding area is wide, so the sliding resistance is large, and it is difficult to slide smoothly on the guide rail. As a result, the drive cable may break due to the load, or the torque of the drive device may increase. Due to insufficient power, it becomes difficult to open and close the panel, and in order to open and close the panel, it is necessary to strengthen the drive cable, and if the drive device is a motor, the torque increases, and if the drive device is a motor, it becomes difficult to open and close the panel. There were other problems. For this reason, efforts have been made to reduce the sliding resistance by applying lubricant such as grease to the sliding surfaces of the slide shoe and guide rail, but over long periods of use, the lubricant runs out and the lubrication function is reduced. Not only does this disappear, but in reality, when the slide show slides inside the guide rail, the slide show scatters the lubricant applied to the sliding surface, causing the lubricant to become In addition, since the sliding surface of the slide show is completely flat, the sliding frictional resistance is large, and the sliding surface inside the guide rail is completely flat. If there is dust, dirt, sand, etc., there is no way for them to escape, so they will rub against the sliding surface of the slide show and cause scratches on the slide show or guide rail, which will increase the sliding resistance. This was one factor.

In view of the above problems, the present invention ensures that the panel maintains its posture without wobbling even when the panel is opened while the vehicle is running, and also reduces sliding resistance to prevent panel movement over a long period of time. This slide show was designed to run smoothly, and its special feature is that guide rails are provided on both sides of the opening in the roof of the vehicle, as well as panels that cover the opening. An opening/closing device provided at the lower part of the panel for lifting, lowering, opening and closing the panel has a slide shoe that is slidably fitted into the guide rail. In the sliding roof opening/closing device for a vehicle, a bulging part or a groove is provided at the upper or lower part of the slide show, and the slide show is slidably fitted into the guide rail without any vertical gap. It is at the point.

Below, the present invention will be explained in detail according to the drawings.
FIG. 1 is a plan view of a vehicle equipped with a sliding roof according to the present invention, and FIG. 2 is a sectional view taken along the line A-A in FIG.

, a lifter 9 that is engaged with the drive body 8 through a cam groove 9a, and a bracket 5 that is pivotally connected to the lifter 9 and for attaching the panel 3, and these drive bodies 8, At the lower ends of the lifter 9 and the bracket 5, there is a slide shoe that is slidably fitted into the guide rails 6 provided on the left and right sides of the opening 2, and supports and moves the panel 3 and the opening/closing mechanism 4. 7 is provided. and,
With this opening/closing mechanism 4, the panel 3 rotates its rear part upward from the state where the opening 2 is closed, centering on the front part, and moves backward while maintaining the tilted state to open the opening 2. be. Figure 3 is the first

In order to provide the slide shoe 107 with elasticity for vibration absorption, a spring groove 10 is provided in the upper part of the slide shoe 107.
7a, a spring member 12 is fitted therein, and the deflection of the spring member 2 absorbs vibrations when the panel 3 is opened and closed.The slide show 107 has an opening/closing mechanism 4 approximately in the center thereof. A fitting hole 13 for attachment to the lower end is provided. FIG. 4 is a perspective view of a slide shoe 17 according to a second conventional example, in which the slide shoe 17 is constructed to have a simple and strong shape without elasticity.

The present invention is as described above, and since the bulges, grooves, or recesses provided on the sliding surface of the slide show are integrated with the slide show body, the wind pressure applied to the panel when the vehicle is running is It has sufficient strength to withstand stress, and by applying a lubricant such as grease to these bulges, grooves, or recesses, this becomes a lubricant reservoir, and the lubricant can be retained even during long-term use, and the guide It is possible to evenly moisten the sliding surface of the guide rail, and dust, dirt, sand, etc. contained on the sliding surface of the guide rail can enter this reservoir without being continuously rubbed by the slide show, so the slide show and This eliminates the need for scratches on the sliding surface of the guide rail, leading to a reduction in sliding resistance. In addition, since there is no need to apply lubricant to the entire sliding part of the guide rail, assembly workability is improved, and when the slide show slides inside the guide rail, only the minimum amount required is applied to the sliding part of the guide rail. Since the surface is not moistened, the area around the guide rail is not contaminated by lubricant, and it looks clean to passengers and the like.
