Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention is applicable to automobiles having a sliding roof (so-called sunroof) on the roof of the vehicle body, in particular, a wind shield at the front edge of the opening opened and closed by the sliding roof. The present invention relates to a deflector structure for a sliding roof of an automobile, which is provided with a deflector for use in automobiles.

(Prior Art) In recent years, automobiles have been put into practical use that have an opening in the roof of the vehicle body and a sliding roof that can be opened and closed to improve the comfort inside the vehicle. In this type of automobile, as shown in FIG. 5, when the sliding roof A is opened during driving, wind is drawn into the cabin C from the rear of the opening B' in the roof. There is a problem in that a resonance phenomenon occurs in the vehicle interior due to the wind while the vehicle is running, and low frequency sound (throb sound) is generated. For this, for example,
As shown in Japanese Patent No. 58-93518, a wind deflector is provided at the front edge of the opening in the roof to prevent wind from being engulfed by the vehicle and to prevent the generation of slob noise. has been proposed, but
If an attempt is made to make the roof opening larger, the deflector must also be made larger, and in this case, a large amount of the wind from the vehicle will hit the deflector, causing it to vibrate, or causing damage to the rear of the deflector. This may cause problems such as the parts being visible to the occupants in the vehicle and spoiling the aesthetics.

(Purpose of the invention) The present invention addresses the above-mentioned problems in the deflector structure of a sliding roof for vehicles.Even when the opening of the roof covered by the sliding roof is enlarged, the deflector can be The purpose is to prevent the generation of slob noise while being compact.

(Structure of the invention) In order to achieve the above object, the deflector structure of a sliding roof for a vehicle according to the invention is characterized by having the following structure.

That is, in a structure that has a sliding roof that can be opened and closed to cover an opening formed in the roof of the vehicle body, and a deflector is provided at the front edge of the opening, the deflector is inserted when the sliding roof is opened. Support the roof so that it stands upright. When the deflector is erected, an air passage is formed between the lower edge of the deflector and the front edge of the opening in the roof, and when the deflector is erected, air passing through the air passage is formed. A rearwardly guiding rectifier is provided at the lower edge of the deflector. The rectifying portion of this deflector is constituted by elastic fins and is provided to cover the lower edge of the deflector.

According to the above configuration, when the sliding roof is opened while the car is running, the wind that tries to enter the passenger compartment from the rear of the opening will flow between the lower edge of the deflector and the front edge of the opening. The airflow flowing rearward through the formed air passage is disturbed and prevents the traveling wind from entering the vehicle interior. By the way, if a deflector is provided at the front edge of the opening and an air passage is formed between the lower edge of the deflector and the front edge of the opening, the air flow will be dispersed at the edge of the lower edge of the deflector. However, since the lower edge of the deflector is provided with a rectifier made of elastic fins so as to cover the lower edge, the air flow due to the edges is reduced. The dispersion of airflow is suppressed and the impact force of the airflow is absorbed, thereby preventing the generation of wind noise as described above.

(Effects of the invention) As described above, according to the invention, in an automobile equipped with a sliding roof that can be opened and closed to cover an opening formed in the roof, and a deflector provided at the front edge of the opening, The air flow passing through the air passage formed between the lower edge of the deflector and the front edge of the opening prevents wind from being drawn into the vehicle interior from the rear of the opening. Therefore, even when the roof opening is made larger, the deflector can be made more compact, and this reduces the problems of the deflector rattling when exposed to the wind while driving or spoiling its aesthetic appearance when viewed from inside the vehicle. This also prevents the occurrence of slobbing noise caused by wind entrainment.

Furthermore, since the flow straightening section made of elastic fins is provided at the lower edge of the deflector so as to cover the lower edge, generation of wind noise due to the airflow passing through the air passage is prevented.

(Example) Examples of the present invention will be described below.

As shown in FIG. 1, a sliding roof frame 3 is fixedly installed below a roof panel 2 constituting a roof 1 of an automobile, and a sliding roof frame 3 is fixed to the roof 1. An opening 4 consisting of an opening and an opening provided in the sliding roof frame 3 is formed. A sliding roof 5 that opens and closes the opening 4 is disposed between the roof panel 2 and the sliding roof frame 3 so as to be movable in the front-rear direction. Further, the front edge of the opening 4,
That is, a plate-shaped deflector 6 that has a substantially constant width and extends in the vehicle width direction is supported on the front side 3a of the sliding roof frame 3.

As shown in FIG. 2, the sliding roof 5 includes an upper panel 7 made of glass, for example, which forms the upper surface of the roof 5, a lower panel 8 which forms the lower surface of the roof 5, and a space between the two panels 7, 8. It is composed of frame members 9, 9 interposed between.

On the other hand, as shown in FIGS. 1 and 2, the deflector 6 has two first holes on the left and right sides of the back surface near the front.
Brackets 10, 10 are fixed to each other, and second brackets 11, 11 are fixed to a position below the first brackets 10, 10 on the front side 3a of the sliding roof frame 3. The brackets 10, 10 and the respective second brackets 11, 11 are connected to the first link members 12, 1.
They are connected to each other via 2. Further, mounting members 13, 13 are fixed to the left and right ends of the deflector 6 at positions closer to the rear, respectively, and the mounting members 13, 13 are fixed to the left and right ends of the deflector 6, respectively, and the mounting members 13, 13 are attached to the side portions 3b, 3b (see FIG. 1) of the sliding roof frame 3. A third bracket 1 is located at the rear of the members 13, 13.
4, 14 are fixed, and the third bracket 14, 1
4 and the respective mounting members 13, 13 are connected to each other via second link members 15, 15 that extend long in the front-rear direction. Here, a spring 16 is attached to a pivot joint between each first bracket 10 fixed to the deflector 6 and the first link member 12, and the spring 16 causes the first bracket 1 to
0 to the rear part of the deflector 6 and the first link member 1
The rear part of No. 2 is biased in the opening direction. When the sliding roof 5 is closed, the pressing members 17 (see FIG. 2) provided at the left and right sides of the roof 5 are pressed against the second pressing member 17 (see FIG. 2).
By pressing the relink member 15 from above, the deflector 6 and the first link member 12 are closed against the biasing force of the spring 16, and when the sliding roof 5 is opened, As shown in FIG. 3, as the pressing member 17 moves rearward together with the roof 5, the biasing force of the spring 16 opens the rear part of the deflector 6 and the rear part of the first link member 12. The first link member 12, the deflector 6, and the second link member 15 rotate in directions a, b, and c, respectively. As a result, the deflector 6 stands up rearward. Also, at this time, the lower edge (front end) of the deflector 6
and the front edge 2a of the opening in the roof panel 2.
An air passage X is formed between the sliding roof frame 3 and the front side 3a of the sliding roof frame 3.

Incidentally, the front end portion of the deflector 6 is bent downward, and an elastic fin 18 is fixed to the tip of the bent portion 6a so as to cover the tip. The elastic fins 18 are provided so as to protrude diagonally rearward with respect to the air passage X (the location between the deflector 6 and the front side 3a of the sliding roof frame 3) when the deflector 6 stands up. There is.

A molding 19 having a substantially U-shaped cross section extending in the vehicle width direction is attached to the end of the front side 3a of the sliding roof frame 3, so that when the sliding roof 5 is closed, the front edge of the lower panel 8 It has become close to the lower surface.

According to the above configuration, when the sliding roof 5 is closed as shown in FIG. 6 is folded and stored in the space between the front side part 3a of the sliding roof frame 3 and the front part of the sliding roof 5.

On the other hand, when the sliding roof 5 is opened, the second link member 15 is pressed by the pressing member 17.
Since the pressing force on spring 1 is released,
The biasing force of the deflector 6 causes the deflector 6 to stand up in an upwardly extending posture. Also, at this time, the deflector 6
An air passage X is formed between the lower edge of the roof panel 2 and the front edge 2a of the opening in the roof panel 2 or the front edge 3a of the sliding roof frame 3. Therefore, when the vehicle is running, most of the wind flows upward after it comes into contact with or comes close to the deflector 6, as shown by arrow A in FIG. 3, but some of it flows downward, as shown by arrow B. The air then passes through the air passage X. In this case, if the deflector 6 is relatively small with respect to the opening 4, the traveling wind flowing upward tends to enter the vehicle interior from the rear side of the opening 4. However, according to the above configuration, the air passage
The airflow passing through and flowing rearward collides with each other, so that the traveling wind becomes turbulent above the rear part of the opening 4. As a result, the force of the traveling wind that tries to enter the vehicle interior is weakened, and even if the deflector 6 is relatively small, the entrainment of the traveling wind into the vehicle interior and the generation of the accompanying slob noise can be prevented. become. In this case, by providing the air passage X below the deflector 6, the air passage
A problem arises in that the airflow passing through the deflector 6 is dispersed at the edge of the lower edge of the deflector 6, causing wind noise. Elastic fin 1 to cover
8, the elastic fins 18 suppress the dispersion of the air flow due to the edges as described above, and absorb the impact force of the air flow, thereby allowing the air to pass through the air passage X. The wind flows smoothly while driving, and wind noise is prevented.

In addition to the configuration in which elastic fins 18 having the shape described above are provided as a rectifier for preventing the generation of wind noise, as shown in FIG. An elastic fin 18' made of a resin member that is elastically deformed by an impact force may be fixed, and in this case as well, the dispersion of the air flow due to the edges is suppressed, and the impact force of the air flow is absorbed.
Wind noise caused by the air flow passing through the air passage X' is prevented.
