Description

  The present invention relates to a vehicle deflector device.

A known deflector device is described in Patent Document 1 described later. This deflector device includes an opening formed in a roof extending in the front-rear direction of the vehicle, a structure provided in front of the opening to be continuous with the opening, a first panel that operates to open and close the opening, and an opening And a second panel that is provided in front of the first panel and tilts up and down with respect to the roof. The second panel operates between an initial position in which the opening is closed together with the first panel, and a deployed position in which a rear portion is expanded upward with respect to the roof in accordance with the operation of the first panel that opens the opening. A sealing member is provided between the structure and the second panel in order to prevent the traveling wind flowing along the structure from being blown into the passenger compartment. The sealing member is formed of an elastic body.
German Patent Publication DE4102660 (see FIGS. 4a and 4b).

  In the deflector device described above, the sealing member is provided on the surface of the structure facing the outside of the vehicle, and is overlapped with the second panel. In this structure, the sealing member needs to have a certain thickness in order to prevent fine vibration of the sealing member due to traveling wind. For this reason, a sealing member protrudes upwards with respect to the surface of a structure, and comprises a convex-shaped level | step difference. Due to this step, the flow of the traveling wind along the surface of the structure is disturbed, and the level of wind noise during traveling may be worse than the level generated in the roof having no opening.

  Further, the sealing member needs to be in pressure contact with the second panel in order to reliably prevent the traveling wind from being blown into the passenger compartment. Since the second panel repeatedly operates between the initial position and the unfolded position, the sealing member that presses against the second panel is repeatedly bent in the vertical direction (bends and deforms) with this repeated operation. Thereby, in a sealing member, degradation, such as a bending trace, arises. Since the sealing member is provided on the surface of the structure, the deteriorated portion faces the outside of the vehicle, and the design is difficult.

  Furthermore, the sealing member formed of an elastic body has at least a certain width in the longitudinal direction of the vehicle. Therefore, when the opening is closed, although the structure and the second panel are arranged in the front-rear direction of the vehicle, the structure and the second panel are intermittently formed at the sealing member portion. It was difficult to say that this is a preferable structure for increasing the thickness.

  Therefore, the present invention has been made in view of the above-described problems, and it is an object of the present invention to further improve designability and not deteriorate the level of wind noise.

  In order to solve the above-mentioned problems, the technical means taken in the present invention is, as described in claim 1, to provide an opening formed in a roof extending in the front-rear direction of the vehicle, and to be continuous with the opening. A structure provided in front of the opening and having a front surface facing the exterior of the vehicle and a back surface facing the passenger compartment, a first panel that operates to open and close the opening, and the first at the opening. A second panel provided in front of the panel, and provided between the structure and the second panel in order to prevent the traveling wind flowing along the surface of the structure from being blown into the passenger compartment. In the vehicle deflector device comprising: a sealing member formed, the second panel has an initial position for closing the opening together with the first panel, and a rear portion in accordance with the operation of the first panel for opening the opening. Is deployed upward with respect to the roof. The sealing member is held at the front portion of the second panel, and is configured to be in pressure contact with the back surface of the structure at the initial position in the upward direction. .

  Preferably, as described in claim 2, the sealing member includes a base portion that is held at a front portion of the second panel, and an engagement that is integrally formed with the base portion and engages with the back surface of the structure. And a thickness of the engaging portion is preferably larger than a thickness of the base portion with respect to a vertical direction of the roof.

  Preferably, as described in claim 3, further comprising a passage provided at the rear of the structure and communicating with the opening and the vehicle compartment, and the engaging portion of the sealing member is located in the passage at the deployed position. It is good to close.

  According to the first aspect of the present invention, the sealing member held at the front portion of the second panel presses upward on the back surface of the structure at the initial position of the second panel. In this structure, since the sealing member does not protrude upward with respect to the surface of the structure, a convex step is not formed in the portion where the traveling wind flows. Thus, the traveling wind flowing along the surface of the structure is not disturbed, and the level of wind noise during traveling is equivalent to the level generated in the roof having no opening.

  In addition, with respect to the front-rear direction of the vehicle, it is only necessary to secure a gap between the front portion of the second panel and the structure so that the second panel can operate between the initial position and the deployed position. The gap size is set to a minimum. As a result, when the opening is closed, the front portion of the second panel and the structure appear to be more connected in the front-rear direction of the vehicle, and the design of the roof is further enhanced.

  Further, the sealing member engages with the rear surface of the structure, that is, the portion that cannot be seen from the surface of the structure (outside of the vehicle). Therefore, when the opening is closed, the sealing member does not affect the design of the roof.

  According to the second aspect of the present invention, the bending rigidity of the engaging portion is higher than the bending rigidity of the base portion in the vertical direction of the roof. As a result, the engaging portion can be more strongly engaged with the back surface of the structure, and the blowing of traveling wind into the passenger compartment can be more reliably prevented. Furthermore, since the base portion is more easily bent and deformed in the vertical direction, the stress (reaction force) acting on the front portion of the second panel holding the base portion is reduced.

  According to the invention described in claim 3, the opening and the passage communicating with the passenger compartment are provided in the rear of the structure. This passage is closed by the engaging portion of the sealing member at the deployed position of the second panel. In this structure, even when the second panel is located at either the initial position or the deployed position, the sealing member held at the front portion of the second panel prevents the traveling wind from being blown into the passenger compartment. That is, since the structure for preventing the traveling wind from being blown into the passenger compartment is realized by one sealing member, the structure of the deflector device is simplified.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  1 and 2 are diagrams schematically showing the structure of a deflector device 10 according to the present invention. The deflector device 10 is provided in an opening 8a formed in the roof 8 of the vehicle. FIG. 1 shows a state where the opening 8a is closed (closed state), and FIG. 2 shows a state where the opening 8a is opened (open state).

  The roof 8 extends in the front-rear direction of the vehicle. The roof 8 has an opening 8a. A windshield 6 (structure) is provided in front of the opening 8a. The windshield 6 is a front glass of the vehicle. The windshield 6 is disposed so as to be continuous with the opening 8a. In the opening 8a, a deflector panel 12 (second panel) and a slide panel 14 (first panel) are provided. The deflector panel 12 is provided in front of the slide panel 14. The opening 8 a is opened and closed by the slide panel 14 and the deflector panel 12. A fixed panel 16 is provided behind the slide panel 14. The deflector panel 12 is mainly made of an iron material, a glass material, a resin material, or a composite material thereof, and the slide panel 14 and the fixed panel 16 are mainly made of a glass material, a resin material, or a composite material thereof. A drive shoe 18 is fixed to the slide panel 14. The drive shoe 18 is connected via a cable 20 to a drive mechanism 22 having a motor (not shown). When the motor of the drive mechanism 22 is supplied with power, the cable 20 moves backward or moves forward depending on the energization direction. As a result, the drive shoe 18 connected to the cable 20 moves, and the slide panel 14 fixed to the drive shoe 18 slides in the front-rear direction. That is, the slide panel 14 slides in the front-rear direction by the driving force of the driving mechanism 22.

  In the closed state of the opening 8a shown in FIG. 1, the deflector panel 12 closes the opening 8a of the roof 8 together with the slide panel 14 (initial position). In this state, when the motor of the drive mechanism 22 is powered, the slide panel 14 slides backward as shown in FIG. 2, and the opening 8a of the roof 8 is opened. With the operation of the slide panel 14, the rear portion 12b of the deflector panel 12 is deployed upward with respect to the roof 8 (deployment position). That is, the deflector panel 12 operates between the initial position shown in FIG. 1 and the deployed position shown in FIG. 2 in accordance with the operation of the slide panel 14 that opens the opening 8a.

  In the open state of the opening 8 a shown in FIG. 2, the traveling wind flowing along the windshield 6 is deflected above the roof 8 by the deployed deflector panel 12. This suppresses the blowing of traveling wind into the passenger compartment.

  A seal member 24 (sealing member) is provided between the windshield 6 and the front portion 12 a of the deflector panel 12. The sealing member 24 prevents the traveling wind flowing along the windshield 6 from being blown into the passenger compartment, and also reliably deflects the traveling wind along the deflector panel 12 and above the roof panel 8.

  Next, the seal member 24 and the surrounding structure will be described with reference to FIGS. 3 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 4 is a cross-sectional view taken along line BB in FIG.

  The seal member 24 is formed of an elastic body such as rubber or elastomer, and is provided between the windshield 6 and the front portion 12 a of the deflector panel 12.

  A holding bracket 12 c and an edge member 12 d are provided on the front portion 12 a of the deflector panel 12. The holding bracket 12c is formed of a rigid body such as iron. The holding bracket 12c is fixed to the lower surface of the base 12e of the deflector panel 12 using a fastening member (not shown). The base material 12e is formed of a transparent or translucent material (glass material). The edge member 12d is made of resin, and is fixed to the base material 12e at the front edge of the deflector panel 12.

  The windshield 6 includes a front surface 6 a facing the outside of the vehicle and a back surface 6 b facing the vehicle interior 30. A resin base 6 c is fixed to the back surface 6 b of the windshield 6. The windshield 6 is supported by the body panel 26. A passage 28 is provided behind the windshield 6. The passage 28 is formed by the deflector panel 12 and the body panel 26. The passage 28 communicates with the opening 8 a of the roof 8 and the vehicle compartment 30.

  The seal member 24 includes a base portion 24a and a lip portion 24b (engagement portion). The base 24a is sandwiched between the holding bracket 12c and the edge member 12d in the roof vertical direction (the vertical direction shown in FIGS. 3 and 4) at the front portion 12a of the deflector panel 12. Thereby, the seal member 24 is held by the front portion 12a of the deflector panel 12. The lip portion 24b is formed integrally with the base portion 24a and has a lip shape. The thickness of the lip portion 24b is thicker than the thickness of the base portion 24a in the roof vertical direction.

  When the deflector panel 12 is positioned at the initial position (shown in FIG. 3), the lip portion 24b is pressed upward against the resin base 6c on the back surface 6b of the windshield 6 so that the deflector panel 12 is at the deployed position (shown in FIG. 4). In some cases, the body panel 26 is pressed downward. In this structure, when the opening 8 a is closed, the seal member 24 does not protrude upward with respect to the surface 6 a of the windshield 6. That is, no convex step is formed in the portion where the traveling wind flows.

Further, when the opening 8 a is opened, the passage 28 communicating with the opening 8 a and the vehicle interior 30 is blocked by the seal member 24.

  In the closed state of the opening 8a, a gap 32 is provided between the front portion 12a of the deflector panel 12 and the windshield 6 in the front-rear direction of the vehicle (the left-right direction in FIGS. 3 and 4). In the gap 32, it is necessary to ensure a size that allows the deflector panel 12 to operate between the initial position and the deployed position. Since the seal member 24 held by the deflector panel 12 is engaged with the resin base 6c on the back surface 6b of the windshield 6 in the closed state of the opening 8a, the seal member 24 is involved in setting the size of the gap 32. Instead, the size of the gap 32 is set to a minimum. Thus, when the opening 8a is closed, the front portion 12a of the deflector panel 12 and the windshield 6 appear to be more connected (consecutively) in the vehicle front-rear direction, and the design of the roof 8 is more enhanced. Rise.

  FIG. 5 is a diagram schematically showing the traveling wind flowing along the windshield 6. Since the seal member 24 is engaged with the resin base 6c on the back surface 6b of the windshield 6 in the upward direction, a convex step due to the seal member 24 is not formed in a portion where the traveling wind flows. Further, in the gap 32 between the front portion 12a of the deflector panel 12 and the windshield 6, the wind speed of the traveling wind becomes almost zero, and turbulence does not occur. Accordingly, the traveling wind flowing along the surface 6a of the windshield 6 is not disturbed, and the level of wind noise during traveling is equivalent to the level generated in the roof having no opening.

  In the above description, an example in which the windshield 6 formed of a glass material is provided in front of the opening 8a and continues to the opening 8a has been described. However, the present invention is not limited to this. For example, a structure in which an iron panel (structure) forming the roof 8 is provided between the opening 8 a and the windshield 6 may be employed.

  As described above, according to the deflector device 10 of the present invention, the seal member 24 held by the front portion 12a of the deflector panel 12 is in the initial position of the deflector panel 12, and the resin base 6c on the back surface 6b of the windshield 6 is used. Press upward on the surface. In this structure, since the seal member 24 does not protrude upward with respect to the surface 6a of the windshield 6, no convex step is formed in the portion where the traveling wind flows. Thereby, the traveling wind flowing along the surface 6a of the windshield 6 is not disturbed, and the level of wind noise during traveling is equivalent to the level generated in the roof having no opening.

  Further, with respect to the longitudinal direction of the vehicle, a gap 32 is secured between the front portion 12a of the deflector panel 12 and the windshield 6 so that the deflector panel 12 can operate between the initial position and the deployed position. Therefore, the size of the gap 32 is set to a minimum. As a result, when the opening 8a is closed, the front portion 12a of the deflector panel 12 and the windshield 6 appear to be more connected in the vehicle front-rear direction, and the design of the roof 8 is further enhanced. Further, the seal member 24 engages with a back surface 6b of the windshield 6, that is, a portion that cannot be seen from the front surface 6a of the windshield 6 (outside of the vehicle). Therefore, when the opening 8a is closed, the seal member 24 does not affect the design of the roof 8.

  Further, according to the present invention, the bending rigidity of the lip portion 24b is higher than the bending rigidity of the base portion 24a in the vertical direction of the roof 8. Thereby, the lip portion 24b can be more strongly engaged with the back surface 6b of the windshield 6, and the blowing of the traveling wind into the vehicle compartment 30 can be prevented more reliably. Furthermore, since the base portion 24a is more easily bent and deformed in the vertical direction, the stress (reaction force) acting on the front portion 12a of the deflector panel 12 holding the base portion 24a is also reduced.

  Further, according to the present invention, the passage 28 communicating with the opening 8 a and the passenger compartment 30 is provided behind the windshield 6. The passage 28 is closed by the lip portion 24 b of the seal member 24 at the deployment position of the deflector panel 12. In this structure, regardless of whether the deflector panel 12 is located at the initial position or the deployed position, the seal member 24 held by the front portion 12a of the deflector panel 12 prevents the traveling wind from being blown into the vehicle compartment 30. That is, since the structure for preventing the traveling wind from being blown into the passenger compartment 30 is realized by the single seal member 24, the structure of the deflector device 10 is simplified.
