Summary of the Invention

Problems to be Solved by the Invention

[0004] The attachment angle of the wing part of the rear spoiler has a great influence on the aerodynamic characteristics of the vehicle, particularly the downforce. In a rear spoiler in which the attachment angle of the wing part can be adjusted, it may be required to finely and reliably adjust the attachment angle in order to finely adjust the aerodynamic characteristics.

Means for Solving the Problems

[0005] The rear spoiler according to the present invention is a rear spoiler for a vehicle that is attached to the rear of the vehicle body, and comprises a wing portion extending in the left-right direction of the vehicle, two stays erected on the left and right sides of the vehicle body and supporting the left and right ends of the wing portion respectively, a fixed-position support structure that supports the wing portion at a fixed position on the stays, and an adjustable support structure that supports the wing portion so that the support position on the stays can be adjusted in the vertical direction of the vehicle. The support position of the wing portion by the fixed-position support structure and the support position of the wing by the adjustable support structure are separated in the front-rear direction of the vehicle body. The adjustable support structure comprises a plurality of positioning pieces having a common outer shape and positioning holes formed at different positions, and a stay that receives one of the plurality of positioning pieces and positions it at a predetermined position on the stay. Outer side in the vehicle width direction The receiving section provided there, The stay includes a fastening bolt that penetrates the positioning hole and fixes the wing portion to a predetermined position through the positioning hole, wherein the receiving portion of the stay is provided with a through-hole, and the fastening bolt is screw-connected to a threaded hole formed on the end face of the wing portion, penetrating the positioning hole and the through-hole from the outside in the vehicle width direction. [Effects of the Invention]

[0006] The mounting angle of the wing can be adjusted by selecting one of several positioning pieces with differently positioned positioning holes. Furthermore, the positioning holes on the positioning pieces ensure the precise positioning of the fastening bolts. This allows for fine and reliable adjustment of the wing's mounting angle. [Brief explanation of the drawing]

[0007] [Figure 1] This is a perspective view showing the rear wing of this embodiment in a partially disassembled state. [Figure 2] This figure shows the positioning piece fitted into the receiving recess of the stay, with the wing section fixed in place. [Figure 3] This figure shows another aspect of the positioning piece. [Modes for carrying out the invention]

[0008] Embodiments of the present invention will be described below with reference to the drawings. In the following description, unless otherwise specified, terms expressing relative positions and orientations such as front, back, left, right, up, and down refer to relative positions and orientations with respect to the vehicle. In each figure, the direction of arrow FR is forward, the direction of arrow UP is upward, and the direction of arrow LH is left.

[0009] Figure 1 shows a rear spoiler 10 that is attached to the rear of the body of a vehicle such as an automobile. In Figure 1, the rear spoiler 10 is shown with some parts disassembled. The rear spoiler 10 includes a wing portion 12 that extends in the left-right direction of the vehicle, and two stays 14 that are erected and fixed to the left and right parts of the vehicle body and support both ends of the wing portion 12. The wing portion 12 may be a thin plate member with an airfoil cross-section. The airfoil cross-section generates downward lift, i.e., downforce. The wing portion 12 is connected to the stays 14 using fastening members such as bolts near the trailing edge and near the leading edge. Near the trailing edge, the wing portion 12 is connected to the stays 14 at a fixed position on the stays 14. The structure that supports the wing portion 12 near the trailing edge is referred to as the fixed-position support structure 16. Near the leading edge, the wing portion 12 is connected to the stays 14 so that the support position of the wing portion 12 can be adjusted in the vertical direction of the vehicle. The structure that supports the wing section 12 near its leading edge is referred to as the adjustable support structure 18. The fixed-position support structure 16 and the adjustable support structure 18 are provided not only on the stay 14 on the right side of the vehicle as shown in the figure, but also on the stay 14 on the left side of the vehicle. The angle of the wing section 12 with respect to the longitudinal direction of the vehicle can be changed by changing the mounting position near its leading edge.

[0010] The fixed-position support structure 16 includes a screw hole (not shown) formed on the end face of the wing portion 12, a through-hole (not shown) formed in the stay 14, and a fixed-position fixing bolt 20 that is screw-connected to the aforementioned screw hole in the wing portion 12. The fixed-position fixing bolt 20 has a shaft portion that passes through the through-hole in the stay 14, and a screw portion is formed at the tip of the shaft portion that is screw-connected to the wing portion 12. The wing portion 12 and the stay 14 are connected by the head of the fixed-position fixing bolt 20 and the end face of the wing portion 12 around the screw hole, which clamps the portion of the stay 14 around the through-hole. The diameter of the through-hole in the stay 14 is approximately the same as the diameter of the shaft portion of the fixed-position fixing bolt 20, and the position of the trailing edge of the wing portion 12 is determined by the relationship between the through-hole in the stay 14 and the fixed-position fixing bolt 20.

[0011] The adjustable support structure 18 includes a screw hole 22 formed on the end face of the wing portion 12, a receiving recess 24 provided on the stay 14, a positioning piece 26 that is received in the receiving recess 24, and an adjustable fixing bolt 28 which is a fastening bolt. Multiple positioning pieces 26 are provided, and one of them is selected and placed in the receiving recess 24 to be used to fix the leading edge of the wing portion 12.

[0012] A through-hole 30 is provided in the receiving recess 24 of the stay 14. The through-hole 30 extends along the direction of the circumference centered on the axis of the fixed-position fixing bolt 20, that is, the support position of the wing portion 12 by the fixed-position support structure 16. The width of the through-hole 30 is approximately equal to the diameter of the shaft portion of the adjustment fixing bolt 28 that passes through the through-hole 30. Multiple positioning pieces 26 are plate-shaped parts having the same external shape, and the receiving recess 24 has a shape that fits the positioning pieces 26. As a result, any positioning piece 26 is positioned at the same location relative to the stay 14 by being received in the receiving recess 24. The position of the positioning piece 26 may be defined by the entire receiving recess 24 by making the circumferential shape of the edge of the receiving recess 24 the same as the external shape of the positioning piece 26, or the position of the positioning piece 26 may be defined at multiple points on the circumferential part of the receiving recess 24 that are far apart from each other.

[0013] Figure 2 shows the positioning piece 26 positioned in the receiving recess 24 of the stay 14, with the wing portion 12 connected to the stay 14 by the adjustment fixing bolt 28. The shaft of the adjustment fixing bolt 28 passes through the positioning hole 32 of the positioning piece 26 and the through-hole 30 of the stay 14, and the threaded tip of the shaft is screw-connected to the threaded hole 22 of the wing portion 12, thereby fixing the wing portion 12 to the stay 14.

[0014] After tightening the fixed position bolts 20 and the adjustment fixing bolts 28, attach the side cover 34 (see Figure 1) to cover the fixed position support structure 16, the adjustment support structure 18 and the recesses around them, and smooth the surface of the stay 14.

[0015] Each of the multiple positioning pieces 26 has a circular positioning hole 32 formed in it. Each positioning hole 32 is formed at a position that overlaps with the through-hole 30 when the positioning piece 26 is placed in the receiving recess 24, and at a position different from the others. A set of positioning pieces for adjusting the mounting angle of the wing portion 12 is formed by multiple positioning pieces 26 with positioning holes 32 formed at different positions. When it is necessary to distinguish between multiple positioning pieces 26 with different positioning hole 32 positions, the subscripts -1, -2, -3, ..., -n are added to the reference numeral 26. The positioning hole 32 is also given the same subscript as the positioning piece 26 in which it is provided. Each positioning hole 32-1, 32-2, ..., 32-n is arranged at a predetermined pitch along the through-hole 30. The arrangement pitch may be smaller than the diameter of the positioning hole 32, and may be less than or equal to the radius. When each positioning piece 26 is housed in the receiving recess 24, the positions of each positioning hole 32-1, 32-2, ..., 32-n are arranged along the same circumference centered on the axis of the fixed-position bolt 20.

[0016] The position in which the wing portion 12 is supported by the adjustable support structure 18 varies depending on the position of the positioning hole 32. Since the support position of the wing portion 12 by the fixed-position support structure 16 is constant, the mounting angle of the wing portion 12 with respect to the vehicle's longitudinal direction can be adjusted by changing the position of the positioning hole 32, that is, by selecting one of the multiple positioning pieces 26. Each positioning piece 26-1, 26-2, 26-3, ..., 26-n may correspond to mounting angles of 0°, 1°, 2°, ..., n° of the wing portion 12, respectively. The adjustable mounting angles do not have to be at equal intervals.

[0017] The adjustable support structure 18 allows for more precise determination of the support position of the wing portion 12, i.e., the mounting angle of the wing portion 12, compared to the case where the wing portion 12 is fixed by bolts that can move along the elongated holes. In the adjustable support structure 18, since each positioning hole 32 is a circular hole, each positioning hole 32 can reliably determine the position of the shaft portion of the adjustment fixing bolt 28 that passes through it without displacement. Therefore, the support position of the wing portion 12 by the adjustable support structure 18 can be reliably determined, and the mounting angle of the wing portion 12 can be reliably adjusted.

[0018] On the other hand, in order to form multiple circular positioning holes in a single positioning piece, the arrangement pitch of the positioning holes must exceed the diameter of the positioning holes. Therefore, fine adjustment of the mounting angle of the wing portion is not possible. In this adjustment support structure 18, multiple positioning pieces 26 with different positions of the formed positioning holes 32 are provided, and by selecting one of these, fine adjustment of the mounting angle is made possible.

[0019] FIG. 3 is a view showing another aspect of the positioning piece. In the above-described positioning pieces 26-1, 26-2, ···, 26-n, one positioning hole 32-1, 32-2, ···, 32-n was formed respectively. In this case, it is necessary to prepare the positioning pieces 26 in the number equal to the number of adjustable mounting angles of the wing portion 12. The positioning piece 50 shown in FIG. 3 can achieve a larger number of adjustable mounting angles with a smaller number. The positioning piece 50 is a plate-like component having the same outer shape as the positioning piece 26. Similar to the positioning piece 26, when it is received in the receiving recess 24 of the stay 14, its position is defined. A plurality of positioning holes 52 are formed in each positioning piece 50. Each positioning hole 52 is formed at a position overlapping the through-hole 30 when each positioning piece 50 is disposed in the receiving recess 24. Further, when each positioning piece 50 is turned over so that the top and bottom are reversed, the outer shape overlaps the state before turning over, and the receiving recess 24 can receive it.

[0020] FIG. 3 shows three positioning pieces 50-1, 50-2, 50-3 that achieve ten mounting angles. The positioning pieces 50-2, 50-3 shown in the lower row show the state where the positioning pieces 50-2, 50-3 in the upper row are turned over so that the top and bottom are reversed. The state of the upper row of the positioning piece 50 is referred to as the upright position, and the state of the lower row is referred to as the inverted position.

[0021] The first positioning piece 50-1 has three positioning holes 52-1, 52-2, and 52-3 formed therein. The positioning hole 52-1 corresponds to the mounting angle of the wing portion 12 being 0°. Similarly, the positioning holes 52-2 and 52-3 correspond to the mounting angles of the wing portion 12 being 5° and 10°, respectively. The second positioning piece 50-2 has two positioning holes 52-4 and 52-5 formed therein. The positioning holes 52-4 and 52-5 in the upright position of the second positioning piece 50-2 correspond to the mounting angles of the wing portion 12 being 1° and 6°, respectively. The positioning holes 52-4 and 52-5 in the inverted position of the second positioning piece 50-2 correspond to the mounting angles of the wing portion 12 being 9° and 4°, respectively. The third positioning piece 50-3 has two positioning holes 52-6 and 52-7 formed therein. The positioning holes 52-6 and 52-7 in the upright position of the third positioning piece 50-3 correspond to the mounting angles of the wing portion 12 being 2° and 7°, respectively. The positioning holes 52-6 and 52-7 in the inverted position of the third positioning piece 50-3 correspond to the mounting angles of the wing portion 12 being 8° and 3°, respectively.

[0022] According to the set of positioning pieces 50 shown in FIG. 3, the three positioning pieces 50 can correspond to the adjustment of the mounting angle of the wing portion 12 in 10 steps.

[0023] As shown in FIG. 1, even with a set of positioning pieces each having one positioning hole, by reversing them as in the case of the positioning piece 50, it is possible to correspond with a number of positioning pieces that is half the number of adjustment steps of the mounting angle of the wing portion 12.

[0024] In the rear spoiler 10, the support position on the trailing edge side of the wing portion 12 is fixed, and the support position on the leading edge side is adjustable, but it may be possible to fix the leading edge side and adjust the trailing edge side.
