Description

  The present invention relates to an aerodynamic addition such as a spoiler and a wing attached to a vehicle body.

  For vehicles, various types of antennas are provided corresponding to the types of radio waves corresponding to broadcasting such as radio, for vehicle telephones, and for vehicle information services, and to requirements for vehicle design. For this reason, the case where one antenna is equipped with a plurality of antennas increases, and there is a problem that a plurality of antenna elements protrude from the vehicle and the appearance of the vehicle is impaired. Therefore, an antenna element is built in a spoiler or the like provided in a vehicle (for example, Patent Documents 1 and 2).

  Aerodynamic additions such as spoilers and wings are generally plate-like members arranged in a horizontal plane. On the other hand, when the radio wave to be received by the antenna element built in the aerodynamic appendage has a deflection surface in the vertical direction, the antenna element also needs to be arranged in the vertical plane. It has been difficult to incorporate such an antenna element in a relatively thin plate-like spoiler or the like.

  The present invention provides an aerodynamic appendage that incorporates an antenna element that is disposed in a substantially vertical plane.

  A vehicle aerodynamic appendage according to the present invention is an aerodynamic appendage provided in a rear part of a vehicle in which an antenna element of a vehicle antenna is incorporated, and the antenna element is plate-shaped, and the plate surface thereof is substantially in a vertical plane. The portion in which the antenna element is disposed is thicker in the vertical direction than the periphery thereof.

  In addition, another vehicle aerodynamic appendage according to the present invention is an aerodynamic appendage provided in a rear part of a vehicle in which an antenna element of a vehicle antenna is built, and the antenna element is plate-shaped, and its plate surface is The portion where the antenna element is disposed is disposed so as to be positioned in a substantially vertical plane, and protrudes in a mountain shape when viewed from the rear of the vehicle.

  The vehicle aerodynamic addition can be a roof spoiler provided at a roof intersection of the vehicle. An antenna element can be built in near the left and right ends of the roof spoiler.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating an appearance of a rear portion of a vehicle 10 to which an aerodynamic addition according to the present embodiment is attached. The vehicle 10 has a vehicle body shape called a minivan, does not have an independent trunk, and has a hatch gate 16 that opens from the rear end of the roof 12 to the upper end of the bumper 14. The aerodynamic addition of the present embodiment is a roof spoiler 18 that protrudes from the rear end of the roof 12 so as to extend rearward. The roof spoiler 18 has an approximately same width as the width of the roof 12 and is an aerodynamic addition for smoothly flowing the airflow flowing on the surface of the roof 12 backward, and its shape is long in the vehicle width direction. It has a thin plate shape that is thin in the height direction.

  On the other hand, in recent years, with communication of vehicles, many antenna elements are provided in the vehicle corresponding to the type of communication for communication with the outside of the vehicle. In addition to receiving radio waves for broadcasting such as conventional radio, antenna elements may be arranged according to the frequency of each radio wave, such as for GPS (Global Positioning System), for car phones, and for emergency information services. . An aerodynamic addition such as a roof spoiler is generally provided so as to protrude from the vehicle body of the vehicle, and if an antenna element is arranged inside this, it can be made invisible or inconspicuous from the outside, and the appearance of the vehicle can be reduced. There is no damage. Some antenna elements have a deflection direction determined by a corresponding radio wave, and therefore the arrangement of the corresponding antenna element needs to correspond to this. For example, the radio wave deflection surface for automobile radio waves is in the vertical direction, and the antenna element must also be arranged in the vertical plane. When such an antenna element is built in a roof spoiler, as described above, the roof spoiler is thin in the height direction of the vehicle, that is, in the vertical direction, and lacks dimensions.

  The roof spoiler 18 of the present embodiment is configured to be thin in the height direction as a whole, and the dimension in the height direction is increased for the portion that houses the antenna element.

  2 to 5 are diagrams showing the detailed shape of the roof spoiler 18. 2 shows a state viewed from above the vehicle, FIG. 3 is a cross-sectional view taken along line AA in FIG. 2, FIG. 4 is a cross-sectional view taken along line BB in FIG. 2, and FIG. It is an enlarged view near the right end.

  In FIG. 2, the upper side is the front of the vehicle 10, and the roof spoiler 18 has a shape elongated in the lateral direction. The dashed-dotted line shown in FIG. 3 represents the rear end of the upper surface of the roof spoiler. As understood from this shape, when the roof spoiler 18 is viewed from the rear of the vehicle, the vicinity of both ends is thick and the upper surface protrudes. It has an approximately triangular mountain shape. The antenna element 20 is disposed inside the thickened portion near both ends. The antenna element 20 is erected on the substrate 22 and is a thin plate-like member as can be seen from FIGS. 4 and 5. This plate is substantially disposed in a vertical plane along the longitudinal direction of the vehicle. When viewed from the rear of the vehicle, the ridge line 24 of the portion protruding in a mountain shape above both ends extends in the vehicle front-rear direction and substantially coincides with the vertical plane on which the antenna element 20 is disposed. With such an arrangement, the roof spoiler as a whole has a thin plate shape so as to achieve an aerodynamic function, and a thickness is taken for a portion in which the antenna element 20 is accommodated, thereby satisfying the requirements regarding the directivity of the antenna element 20. Arrangement is realized.

  The roof spoiler 18 of the present embodiment has a substantially triangular mountain shape in the vicinity of its left and right ends. However, other shapes such as a trapezoidal shape having a flat portion on the upper surface, a fin shape standing vertically, etc. It can be. Further, instead of projecting to the upper surface side, the upper surface can be flattened and projected to the lower surface side. Furthermore, it can be made to project in both the upper surface side and the lower surface side so as to form a rhombus when viewed from the rear. Moreover, not only an edge part but a part with thickness can be provided in a part of width direction, and an antenna element can also be arrange | positioned there.

  In the embodiment, the roof spoiler of the minivan has been described. However, the present invention can be applied to other vehicle forms, for example, a spoiler such as a one box or a sedan. Furthermore, the sedan can be applied to a spoiler provided at the rear end of the trunk portion. In addition to the spoiler, a part in the width direction of an aerodynamic addition such as a wing that is placed away from the vehicle body via a stay etc., for example, a thick part near the left and right ends, and an antenna element is placed here You can also Further, the blade end plate provided substantially perpendicular to the end of the wing is also a thicker portion than the wing portion of the wing, and the antenna element can be disposed therein.
