  In order to enhance the aerodynamic effect of the rear spoiler, it is effective to increase its dimension, particularly the dimension projecting to the rear of the vehicle. Further, in recent vehicles, the rear spoiler tends to increase in size from the viewpoint of design. However, when the rear spoiler is enlarged, there is a problem that it is difficult to ensure its rigidity.

  For example, in a rear spoiler that extends rearward long, the area of the upper surface of the rear spoiler becomes large, and the rigidity is reduced unless a large thickness dimension is secured for the upper surface. If the rigidity of the upper surface of the rear spoiler is insufficient, the upper surface may be deformed by an external force (for example, aerodynamic force) acting on the upper surface.

  Further, in a rear spoiler that extends rearwardly, it is necessary to increase the vertical dimension on the vehicle side, so that the lower end of the rear spoiler may be attached so as to cover the upper end of the rear glass as disclosed in Patent Document 2. . Further, the rear spoiler that extends rearward has a large moment around the mounting portion due to the external force acting on the rear end portion, and is easily bent so that the rear spoiler rotates around the mounting portion. When the rear spoiler mounted so as to cover the upper end of the rear glass rotates around the mounting portion, the lower end portion of the rear spoiler on the vehicle side comes into contact with and presses the rear glass, which is not preferable.

  The present invention has been made in view of the above circumstances, and is a rear spoiler that is lightweight and highly rigid, can be secured to a vehicle with a small amount of fastening parts and can be attached to a vehicle, and can reduce the load on the rear glass. The purpose is to provide.

  The rear spoiler of the present invention is a rear spoiler installed on the rear side of a roof of a vehicle, and the rear spoiler includes an outer member having an opening on the vehicle side, and an inner member joined in the opening of the outer member. And the inner member has at least a first joint portion joined to an upper inner surface of the outer member near the end of the opening, and a lower inner surface of the outer member near the end of the opening. And a third joint that is joined to the upper inner surface of the outer member on the back side from the opening to the first joint.

  According to the rear spoiler of the present invention, the inner member is joined to the first inner joint portion that is joined to the upper inner surface in the vicinity of the end portion of the outer member opening and the lower inner surface in the vicinity of the end portion of the outer member. And a third joint that is joined to the upper inner surface of the outer member on the back side from the opening with respect to the first joint. Thereby, the rigidity of a rear spoiler can be improved, without thickening an outer member. That is, the opening on the front side of the outer member is blocked by the front surface portion of the inner member that connects the first joint portion and the second joint portion, and the rigidity is increased, and the rear side of the outer member is the second joint portion. The rigidity is increased by the rear surface portion of the inner member that connects the first joint portion and the third joint portion.

  In particular, the rear side of the upper part of the outer member is firmly supported from the inner surface by the rear surface portion of the inner member in which the third joint portion is integrally formed. Thereby, the deformation | transformation of the rear spoiler upper surface by the external force from upper direction can be suppressed small, and the external force can be efficiently transmitted to a vehicle.

  In addition, an attachment portion for fastening and fixing the rear spoiler to the vehicle body panel is formed on the front surface portion connecting the first joint portion and the second joint portion of the inner member, and the front portion below the attachment portion has A contact portion that can contact the vehicle body panel is formed. Thereby, high rigidity can be ensured with few fastening parts, and a rear spoiler and a vehicle can be firmly fixed. That is, when an external force directed downward is applied to the rear side of the rear spoiler, the abutting portion comes into contact with the vehicle body panel and supports the rear spoiler, so that the rotation of the rear spoiler around the mounting portion can be suppressed.

  Further, by placing the end of the opening of the outer member in the vicinity of the second joint portion away from the rear glass of the vehicle, the pressure on the rear glass by the rear spoiler can be reduced. Moreover, you may arrange | position a buffer member between the said front part below the said attachment part, and a rear glass. Thereby, the pressing force from the rear spoiler can be dispersed, and the load on the rear glass can be reduced. In particular, by arranging the buffer member on the bonding region between the vehicle body panel and the rear glass, the rear glass can be appropriately supported from the inner and outer surfaces, and the rear glass can be prevented from being bent.

  Further, the inner member may be integrally formed with a reinforcing rib that connects the front surface portion and the rear surface portion. Accordingly, the rigidity of the rear spoiler can be further increased, and the rear spoiler can be firmly supported by the vehicle. In particular, by providing the reinforcing rib at a place where the attachment portion is formed, an external force acting on the rear side of the rear spoiler can be efficiently transmitted to the attachment portion and the contact portion. As a result, the deformation of the rear spoiler can be suppressed and the aerodynamic force received by the rear spoiler can be effectively used to improve the running performance of the vehicle.

  Furthermore, you may form the said contact part also in the intermediate position of the said adjacent attachment part. Thereby, even higher rigidity can be secured without increasing the number of fastening parts.

It is a disassembled perspective view which shows schematic structure of the rear spoiler which concerns on embodiment of this invention. It is a cross-sectional view same as the above. It is a cross-sectional view of the location where the attachment part and the contact part were formed. It is a cross-sectional view of the location where the contact part was formed.

  Hereinafter, the rear spoiler which concerns on embodiment of this invention is demonstrated in detail based on drawing.

  FIG. 1 is an exploded perspective view showing a schematic structure of a rear spoiler 1 according to an embodiment of the present invention. In FIG. 1, the diagonally lower left side of the page is the front of the vehicle, and the diagonally upper right side of the page is the rear of the vehicle.

  The rear spoiler 1 is a component that is attached to an upper end portion of a rear gate that can be freely opened and closed at a rear end opening portion of an automobile or the like. As shown in FIG. 1, the rear spoiler 1 includes an outer member 10 and an inner member 20 each extending in the vehicle width direction.

  The outer member 10 and the inner member 20 are made of, for example, a synthetic resin material such as ABS resin or AES resin, and are integrally formed by injection molding or the like. The outer member 10 and the inner member 20 are joined to each other by an adhesive or the like.

  FIG. 2 is a cross-sectional view showing a schematic structure of the rear spoiler 1. In FIG. 2, the left side of the paper is the front of the vehicle, and the right side of the paper is the rear of the vehicle.

  As shown in FIG. 2, the outer member 10 is a member constituting a design surface of the rear spoiler, is curved convexly toward the rear of the vehicle 30, and has an opening 16 formed on the front side (vehicle 30 side). ing. That is, the outer member 10 includes an upper portion 11 disposed on the roof rear extension of the vehicle 30, a rear end portion 13 formed so as to fold the rear end portion of the upper portion 11 downward, and the rear end portion 13. The lower part 12 which is continuously formed and extends toward the front side of the vehicle is a member formed integrally. The outer surface of the outer member 10, that is, the surface continuous from the upper surface 11a of the upper portion 11 to the lower surface 12a of the lower portion 12 is exposed to the outside and constitutes the design surface of the rear spoiler 1 as described above.

  The inner member 20 has a function of attaching the rear spoiler 1 to the vehicle 30, and is inserted into the outer member 10 from the opening 16 of the outer member 10 and joined to the outer member 10.

  The inner member 20 includes a first joint portion 21 joined to the front side of the upper inner surface 11b of the outer member 10, a second joint portion 22 joined to the lower inner surface 12b of the outer member 10, and an upper inner surface of the outer member 10. It is integrally formed by connecting the third joint portion 23 joined to the rear side of 11b.

  Specifically, the rear side of the first joint portion 21 and the front side of the second joint portion 22 are connected by the front surface portion 24 of the inner member 20, and the rear side of the second joint portion 22 and the third joint portion. 23 is connected to the front side of the inner member 20 by a rear surface portion 25 of the inner member 20.

  The first joint portion 21 has a first joint surface 21 a that faces the upper inner surface 11 b of the outer member 10 in the vicinity of the end portion 14 (end portion on the upper vehicle side) of the opening 16, and the first joint surface 21 a It is joined to the upper inner surface 11b of the outer member 10 by an adhesive or the like (adhesive, adhesive, adhesive tape, thermal fusion, etc.).

  Similarly, the second joint portion 22 has a second joint surface 22a facing the lower inner surface 12b of the outer member 10 in the vicinity of the end portion 15 (end portion on the lower vehicle side) of the opening 16, and the second joint portion The surface 22a is joined to the lower inner surface 12b of the outer member 10 with an adhesive or the like.

  In this way, the first joint portion 21 and the second joint portion 22 of the inner member 20 are joined to the upper inner surface 11b and the lower inner surface 12b of the outer member 10, respectively, so that the first joint portion 21 and the second joint portion 22 are joined. The opening 16 on the front side of the outer member 10 is closed by the continuous front surface portion 24. That is, a hollow space is defined inside the rear spoiler 1 by being surrounded by the front surface portion 24 of the inner member 20 and the outer member 10. Thereby, the rigidity can be improved, suppressing the weight increase of the rear spoiler 1. FIG.

  Here, instead of the inner member 20 according to the present embodiment, when an inner member that is convexly curved toward the rear of the vehicle 30 and opens on the vehicle 30 side is employed in the same manner as the outer member 10, the front side of the rear spoiler is adopted. There is a problem that the opening shape remains and the rigidity on the front side is lowered. Such a problem occurs when, for example, a molding die for molding the inner member is configured such that its die-cutting direction is the front-rear direction with respect to the vehicle 30 as in the molding die for molding the outer member 10. .

  On the other hand, in the rear spoiler 1 according to the present embodiment, the opening portion 16 of the outer member 10 is blocked by the front surface portion 24 of the inner member 20 as described above, so that the deformation on the front side is restricted to increase the rigidity. Can do. Such a configuration is possible by configuring the mold for molding the inner member 20 so as to be punched in the vertical direction.

  The third joint portion 23 has a third joint surface 23a facing the upper inner surface 11b of the outer member 10 on the back side from the opening 16 with respect to the first joint portion 21, and the third joint surface 23a is the outer joint surface 23a. The member 10 is joined to the upper inner surface 11b. Accordingly, the rear side of the upper portion 11 of the outer member 20 is firmly supported from the inner surface 11b side by the third joint portion 23 of the inner member 20 and the rear surface portion 25 connected thereto. As a result, the rigidity of the upper part 11 which becomes the upper surface of the rear spoiler is increased, and deformation due to an external force acting thereon can be suppressed.

  As described above, the thickness of the outer member 10 is increased by attaching and joining the inner member 20 integrally formed by connecting the first to third joining portions 21, 22, and 23 to the inner surface of the outer member 10. Without this, the rigidity of the rear spoiler 1 can be increased. Further, deformation of the rear spoiler 1 can be suppressed, and external force acting on the rear spoiler 1 can be efficiently transmitted to the vehicle 30.

  In addition, between the end part 14 on the vehicle 30 side of the rear spoiler 1 and the vehicle body panel 31 of the vehicle 30, the vehicle body panel 31 is prevented from being damaged due to contact with the rear spoiler 1, and the gap is sealed. A buffer member 33 is provided. The buffer member 33 is a sheet material made of a soft foam rubber material such as foamed polyurethane, for example.

  In addition, a buffer member 34 made of a soft foam rubber material is provided between the front portion 24 of the inner member 20 and the rear glass 32. Here, the rear glass 32 and the vehicle body panel 31 are joined by an adhesive 35 made of, for example, a urethane resin adhesive, and the buffer member 34 is located at a position corresponding to a joint location (adhesion region) by the adhesive 35. Affixed to The buffer member 34 disperses the pressing force of the rear spoiler 1 and lightly presses the bonding area near the upper end of the rear glass 32, thereby preventing the rear glass 32 from bending. The buffer member 34 also has a function of sealing the gap between the rear spoiler 1 and the rear glass 32.

  Further, the end 15 of the opening 16 in the vicinity of the second joint portion 22, that is, the end 15 on the vehicle 30 side of the lower portion 12 is installed away from the rear glass 32 of the vehicle 30. Thereby, the pressure to the rear glass 32 by the rear spoiler 1, especially the pressure outside an adhesion area | region with the vehicle body panel 31, can be reduced, and the bending of the rear glass 32 can be prevented.

  FIG. 3 is a cross-sectional view of a portion where the attachment portion 26 and the abutting portion 27 of the rear spoiler 1 are formed. In FIG. 3, the left side of the paper is the front of the vehicle, and the right side of the paper is the rear of the vehicle.

  As shown in FIG. 3, an attachment portion for mechanically fixing the rear spoiler 1 to the vehicle body panel 31 of the vehicle 30 is provided on the front surface portion 24 connecting the first joint portion 21 and the second joint portion 22 of the inner member 20. 26 is formed.

  Specifically, the mounting portion 26 has a mounting hole that penetrates the front surface portion 24, a surrounding reinforcing structure, and a mounting surface that corresponds to the outer surface of the vehicle body panel 31. It is fixed to the vehicle body panel 31 by a fastener 36 composed of

  The attachment portion 26 is provided at a plurality of locations separated in the extending direction of the rear spoiler 1, that is, in the vehicle width direction of the vehicle 30. The position in the vehicle width direction where the attachment portion 26 is formed is substantially the same as the position where the abutting portion 27 and the reinforcing rib 28 described later are formed. For example, the attachment portion 26 is disposed at six locations at predetermined intervals in the vehicle width direction corresponding to the positions of the reinforcing ribs 28 shown in FIG.

  As shown in FIG. 3, a contact portion 27 that can contact the vehicle body panel 31 is formed below the attachment portion 26. The abutting portion 27 has a shape corresponding to the outer surface shape of the vehicle body panel 31 and is formed with a predetermined gap from the vehicle body panel 31.

  Here, between the abutting portion 27 and the vehicle body panel 31, a buffer member 37 for preventing the vehicle body panel 31 from being damaged and sealing the gap is disposed. That is, the fact that the vehicle body panel 31 and the abutting portion 27 can contact each other means that both can be pressed via the buffer member 37. That is, in a normal state, the abutting portion 27 does not press the vehicle body panel 31 strongly, and is in light contact with the vehicle body panel 31 via the buffer member 37.

  The predetermined gap is a gap such that the contact portion 27 and the vehicle body panel 31 come into contact with each other before the end 15 on the lower vehicle side of the rear spoiler 1 comes into contact with the rear glass 32. Thus, by setting the gap between the abutting portion 27 and the vehicle body panel 31 so that the abutting portion 27 and the vehicle body panel 31 abut before the end portion 15 at the lower front of the rear spoiler 1 abuts against the rear glass 32. The contact between the rear front end 15 of the rear spoiler 1 and the rear glass 32 can be prevented.

  Specifically, when a downward external force is applied to the upper surface 11a of the rear spoiler 1, the abutting portion 27 and the vehicle body panel 31 come into contact with each other via the pressed and crushed shock absorbing member 37 and are pressed strongly against each other. . Thereby, the rear spoiler 1 is supported by the contact portion of the vehicle body panel 31, and the rotation of the rear spoiler 1 around the attachment portion 26 is suppressed. Then, contact between the rear front end 15 of the rear spoiler 1 and the rear glass 32 can be prevented. Thereby, the pressing load to the rear glass 32 by the rear spoiler 1 can be reduced.

  In addition, providing a predetermined gap between the abutting portion 27 and the vehicle body panel 31 does not affect the workability in the process of attaching the rear spoiler 1 to the vehicle 30 (fitting process). That is, since the gap between the abutting portion 27 and the vehicle body panel 31 is set in consideration of a predetermined variation, there is no area between the abutting portion 27 and the vehicle body panel 31 in the attachment process, and can be easily assembled.

  In addition, a reinforcing rib 28 that connects the front side and the rear side of the second joint portion 22 is integrally formed on the cross section where the attachment portion 26 and the abutting portion 27 are formed. Specifically, the reinforcing rib 28 connects the second joint portion 22, the front surface portion 24 connected to the front side of the second joint portion 22, and the rear surface portion 25 connected to the rear side of the second joint portion 22. , Each has a substantially wall-like shape standing substantially perpendicular to each other.

  Thus, by providing the substantially wall-shaped reinforcing rib 28 that connects the front surface portion 24 and the rear surface portion 25, the rigidity of the rear spoiler 1 can be further increased while suppressing an increase in the weight of the rear spoiler 1. In particular, by forming the reinforcing rib 28 at substantially the same position in the vehicle width direction with respect to the mounting portion 26 and the abutting portion 27, the support force of the rear spoiler 1 by the vehicle 30 can be increased, and the external force acting on the rear spoiler 1 can be increased. It can be efficiently transmitted to the vehicle 30.

  Furthermore, a reinforcing rib 29 may be provided that connects the third joint portion 23 and the rear surface portion 25 and is erected substantially perpendicular to each other. Thereby, the rigidity of the rear side of the rear spoiler 1 can further be improved.

  FIG. 4 is a cross-sectional view of a portion where the abutting portion 27 is formed between the adjacent mounting portions 26 of the rear spoiler 1. In FIG. 4, the left side of the paper is the front of the vehicle, and the right side of the paper is the rear of the vehicle.

  As shown in FIG. 4, the abutting portion 27 may be formed at a location where the attachment portion 26 (see FIG. 3) is not provided. For example, you may form the contact part 27 between the attaching parts 26 spaced apart in the vehicle width direction, ie, between the attaching part 26 and the other attaching part 26 adjacent to it.

  Thereby, the attachment rigidity of the rear panel 1 can be further increased without increasing the number of fasteners 36 (see FIG. 3). Moreover, it can prevent that the edge part 15 by the side of the lower vehicle of the rear spoiler 1 contacts the rear glass 32, and can reduce the pressing load to the rear glass 32 by the rear spoiler 1.

  According to the rear spoiler 1 described above, the rigidity of the rear spoiler 1 itself is high and high rigidity can be secured for attachment to the vehicle 30, so that the degree of freedom in design can be increased. For example, it is possible to ensure a large overhanging length of the vehicle 30 without increasing the thickness in the vertical direction. Thereby, it is possible to exhibit excellent aerodynamic performance while preventing the driver's view from being covered by covering the rear glass 32.

  The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
