Description

[Detailed Description of the Invention] Industrial Application Field This invention is a sliding roof structure for a vehicle, particularly for preventing wind throb (spatial resonance noise) and roof vibration caused by airflow when the roof opening is opened. This relates to a sliding roof structure.

BACKGROUND OF THE INVENTION Generally, there are various sunroofs for automobiles, such as a removable type, a tilt-up type, and a sliding type. There are also outer slide types and inner slide types of this slide type, and examples of the inner slide type include those exhibiting a structure as shown in FIGS. 4 and 5, for example.

That is, an opening 2 is formed in the roof 1, and a lid 3 for opening and closing the opening 2 is disposed so as to be slidable in the longitudinal direction of the vehicle by a mechanism not shown. A sunshade 4 that blocks light rays is also slidably disposed on the top. When the lid 3 and sunshade 4 slide backward, that is, the opening 2
A storage chamber 5 that accommodates the lid 3 and sunshade 4 when opened is formed by a roof panel 6 and a frame 7. When the lid 3 is stored in the storage chamber 5, the top side of the lid 3 (between the lid 3 and the roof panel 6), or the bottom side of the lid 3 (between the lid 3 and the sunshade 4)
Space parts A and B are generated in each of the areas. In other words, these spaces A and B are provided to allow the lid 3 to slide. Further, a deflector 8 is provided at the front edge of the roof opening 2 to prevent the wind from entering the roof opening 2 as much as possible. Note that in the figure, reference numeral 9 is a front windshield, and 10 is a roof trim.

However, in such a conventional sliding roof structure, a deflector 8 is provided to restrict the flow direction of the traveling wind and prevent the generation of vortices in the roof opening 2, but this alone is insufficient. Instead, the wind from the vehicle enters the space A on the top side of the lid 3 and the space B on the bottom side of the lid 3 as shown by arrows a and b, respectively.
Then, the air shown by arrow a flows around behind the lid 3, and this air interferes with the air shown by arrow b, creating a vortex, which generates windthrob (cavity resonance sound) and roof 6 vibration. , there is a problem. This applies in particular to the roof opening 2
This is noticeable in a vehicle body with a large size or a vehicle body with a high storage compartment 5 side.

This type of structure is also described in Japanese Utility Model Application Publication No. 111619/1983.

Therefore, as a countermeasure, Utility Model Application No. 60-51122,
The one described in Utility Model Application No. 56-4917 or Sho 58-61621 has been proposed.

Problems to be Solved by the Invention However, such a device has the following problems. First, Utsukai Showa 60-51122
In this case, the air baffle plate hangs on the inside of the vehicle during the opening/closing operation (sliding), which is dangerous for the occupants.
In addition, in the case of Utility Model Application Publication No. 56-4917, when the sliding lid is made transparent, when the sliding lid is closed, the rectifying plate faces forward and lies almost horizontally, so the lighting area becomes narrower and When the sliding lid slides in the front-back direction, the sliding lid and the current plate come into contact with each other and a sliding sound is generated. Furthermore, in the case of Utility Model Application Publication No. 58-61621, since a strip member is provided on the upper surface of the cover panel that opens and closes the roof opening, the strip member protrudes outside the vehicle when the cover panel is closed. Therefore, there are problems in that the quality of the external appearance is deteriorated and the air resistance increases when the vehicle is running.

Means for Solving the Problems In order to solve the problems, the present invention provides a lid that opens and closes an opening formed in the roof of the vehicle, which is slidable in the longitudinal direction of the vehicle, and which accommodates the lid. A storage chamber is formed on the rear side of the opening, and the storage position of the lid in the storage chamber is set lower than the closed position of the opening, and there is a difference between the closed position and the storage position. In the sliding roof structure for a vehicle that slides diagonally between the lids, when the lid is stored in the storage chamber,
The present invention is characterized in that a sliding roof structure for a vehicle is provided in which a blocking portion for blocking a space generated on the lower surface side of the lid is erected on the side of the storage chamber along substantially the width direction of the vehicle.

Effect: According to this means, when the lid is slid toward the rear of the vehicle and stored in the storage compartment, and the roof opening is opened, a space is created on the upper surface side and the lower surface side of the lid in the storage compartment. do. However, this space on the bottom side is blocked off in the vehicle longitudinal direction by a blocking part, so when the vehicle is running, the air that has entered the space on the top side and the air that has entered the space on the bottom side have been separated. Interference is prevented, and since the lid is always pressed against the blocking part while the vehicle is running, wind slobs, roof vibrations, etc. are suppressed. Further, the lid is set at a lower position when the lid is stored in the storage chamber than when the opening is closed, and slides diagonally between the closed position and the storage position.
Since the blocking part is provided in the space on the bottom side of the lid, unlike those that slide horizontally, the sliding contact time between the blocking part and the lid, etc. is short, which reduces sliding noise. . Furthermore, in the lid stowed state, this blocking portion is located within the storage compartment, so it does not hit the occupant.

Example Hereinafter, this invention will be explained based on examples.

1 to 3 are diagrams showing one embodiment of the present invention.

First, the structure will be described. Reference numeral 11 in the figure is a roof, and the roof 11 is composed of a roof panel 12, a frame 13, a roof trim 14, and the like. These roof panels 12 and frames 13
Also, openings are formed in the roof trim 14, and the roof 11 has an opening 1 that opens the interior of the vehicle.
5 have been established. A weather strip 16 for sealing between the frame 13 and the roof panel 12 is attached to the periphery, and an opening periphery 14a of the roof trim 14 is attached to the opening periphery by a welt 17.

A lid 18 opens and closes the opening 15.
A sunshade 19 that blocks light rays is disposed so as to be slidable in the longitudinal direction of the vehicle by a mechanism (not shown) supported on the frame 13. The lid 18 is, for example, electrically operated, and the sunshade 19 is manually operated. When the lid 18 is closed, the sunshade 19 is independently slidable, and by sliding it rearward, light can be let in through the transparent lid 18. Of course, when the lid 18 is opened, the sun shade 19 is configured to slide rearward in conjunction with the lid 18. A storage chamber 20 is formed on the rear side of the opening 15 to accommodate the lid 18 and the shade 19 when the opening 15 is opened. This storage room 2
0 is formed by the roof panel 12 on the rear side of the opening 15 and the frame 13.

The lid 18 is a transparent plate-shaped lid body 18a.
The opening periphery 12 of the roof panel 12 is located at the periphery of the roof panel 12.
A sealing member 18b that contacts and seals a is attached. And this lid 18
The storage position shown in FIGS. 1 and 2 is set lower than the closed position of the opening 15. Therefore, the sliding situation of this lid 18 is as follows.
Although not shown, it does not move horizontally, but moves diagonally between the closed position and the storage position. In the stored state of the lid 18, there is a space A on the top side of the lid 18 (between the lid 18 and the roof panel 12), and a space A on the bottom side of the lid 18 (between the lid 18 and the sunshade 19). B
However, each of these is inevitable. In other words, these spaces A and B are provided to allow the lid 18 to slide.

On the other hand, as shown in FIG. 3, the sunshade 19 is provided with a blocking member 21 at the front end 19b of a sunshade main body 19a, which is approximately the same size as the lid 18, over the entire width in the vehicle width direction. This blocking member 21 is formed from a long plate-shaped fixed plate 21a made of a steel plate and a seal rubber 21b made of rubber which is a blocking part.
A is riveted, and is fastened together with a handle 23 with a bolt 24 as shown in FIG. Then, in the stored state in the storage chamber 20, the tip portion 21c of the seal rubber 21b of this blocking member 21
By coming into contact with the lower surface of the lid 18, the seal rubber 21b, which extends substantially in the vehicle width direction, blocks off the space B.

Further, at the front end of the opening 15, a tiltable defleter 25 is disposed to prevent wind from entering the roof opening 15.

Note that the reference numeral 26 in the figure is a front window glass.

Next, the operation of the sliding roof structure having such a configuration will be explained.

By sliding the lid 18 and sunshade 19 rearward and storing them in the storage chamber 20 as shown in FIGS. 1 and 2, the roof opening 15
to open. When driving in this state, the deflector 25 somewhat reduces the intrusion of the traveling wind into the roof opening 15, but as shown in FIG. It invades. The traveling wind enters into the space A on the upper surface side of the lid 18 from the opening C as shown by the arrow a, passes through this space A, and goes around behind the rear end 18c of the lid 18. It enters the space B on the lower surface side of the lid 18 and flows forward.
The flow is blocked by the seal rubber 21b of the blocking member 21. On the other hand, an attempt is made to enter the space B through the opening D as shown by arrow b, but since the seal rubber 21b is disposed near the opening D, it is blocked by the seal rubber 21b. There is no possibility of intrusion deep into the storage room 20.
By blocking the airflow shown by the arrow a and the airflow shown by the arrow b with the seal rubber 21b in this manner, interference between the two is prevented, and vibrations of the wind slot and the roof 11 are suppressed. especially,
The wind shown by arrow a enters to press the upper surface of the lid 18 and press the blocking member 21, and the rollers (not shown) that slide the lid 18 also act to be pressed against the guide rail, so the lid 18 dances and makes noise. (so-called low-level sounds) are not generated.

For example, when the lid 18 is slid rearward, the lid 18 moves diagonally from the roof opening 15 to a lower storage position, and the blocking member 21 slides off the lower surface of the lid 18. Because it is arranged in the side space B,
Compared to a device that slides in a substantially horizontal direction, the sliding contact time of the blocking member 21 to the lid 18 can be shortened, resulting in a reduction in sliding noise. Of course, the same applies when closing the lid 18. By providing the cut-off part on the underside of the lid,
During sliding, sand and other particles will not get into the sliding area and cause numerous hairline scratches, which will impair transparency and reduce the appearance quality.

Furthermore, as in this example, Sunshade 1
9, the seal rubber 21b is located near the opening D of the space B, and most of the traveling wind enters into the space B from this opening D. Therefore, the generation of sound due to the vibration of the air column within this space B is also prevented. Furthermore, in this embodiment, a seal rubber 21b made of rubber is provided and brought into contact with the lid 18, so that the airflow blocking performance is further improved, and as a result, wind slob etc. can be prevented more effectively. That will happen.

In the above embodiment, a seal rubber 21b made of rubber is used as a blocking part which is a component of the present invention.
However, the present invention is not limited to this, and various shapes, materials, mounting methods, etc. may be used as long as the function of blocking the space B is achieved. Furthermore, in cases where the sunshade 19 is not installed, it goes without saying that it may be placed on the frame 13 side.

Effects of the invention As explained above, according to this invention,
When the roof opening is opened, the air that has entered the space on the top side of the lid in the storage compartment and the air that has entered the space on the bottom side of the lid are blocked by the blocking part, thereby preventing interference between the two. This makes it possible to suppress wind throttling and roof panel vibration. In addition, the storage position of the lid in the storage chamber is set lower than the closed position of the opening,
Since the lid slides diagonally between the closed position and the storage position, and the shut-off part is provided in the space on the bottom side of the lid, the low-level rattling noise caused by the force pushing down the lid is not generated, and the shut-off part is The sliding contact time between the part and the lid etc. can be shortened, the sliding noise can be reduced, and there is less wear on the shutoff part.
It has a practical effect of being easy to open and close.
