Description

Technical Field

[0001] This invention relates to a fairing component. Background Technology

[0002] Japanese Patent Application Publication No. 2007-83798 discloses a structure in which a convex top is formed in the center of the fairing vent in the vehicle width direction, and by making the convex top protrude upwards more than the rear end of the hood, the windshield wipers are prevented from being hit by the driving wind. Summary of the Invention

[0003] However, in the structure described in Japanese Patent Application Publication No. 2007-83798, a convex top is formed only on a part of the fairing ventilation panel, so there is room for improvement from the viewpoint of effectively suppressing the impact of driving wind on the wipers.

[0004] The purpose of this invention is to obtain a fairing component that can effectively suppress the impact of driving wind on the windshield wipers.

[0005] According to the fairing component involved in technical solution 1, it has: a main body portion disposed at the lower part of the windshield and extending along the width direction of the vehicle, and a wiper is mounted thereon; and a protrusion portion disposed in the main body portion at a position further forward of the vehicle than the wiper, and protruding further upward of the vehicle than the rear end of the hood, and in a planar view opposite to the entire area of ​​the wiper in the non-operating state in the longitudinal direction of the vehicle.

[0006] In the fairing component of technical solution 1, a main body is provided at the lower part of the windshield, extending along the width direction of the vehicle, and a windshield wiper is mounted thereon. Furthermore, a protrusion is provided in the main body at a position further forward of the vehicle than the windshield wiper, protruding further upward of the vehicle than the rear end of the hood. As a result, the airflow flowing along the hood impacts the protrusion and is directed upwards, thus preventing the airflow from impacting the windshield wiper.

[0007] Furthermore, the protrusion is positioned in the longitudinal direction opposite to the entire area of ​​the non-operating windshield wipers when viewed from a planar perspective. Therefore, in the entire area where the windshield wipers are installed, the driving wind can impact the protrusion and flow upwards.

[0008] According to the fairing component involved in technical solution 2, in technical solution 1, the protrusion extends from one end of the main body in the vehicle width direction to the other end.

[0009] In the fairing component involved in technical solution 2, the protrusion extends from one end to the other end in the vehicle width direction, thus preventing the driving wind from flowing into the vehicle width direction through the gap of the protrusion and impacting the windshield wiper.

[0010] According to the fairing component involved in technical solution 3, in technical solution 1, the protrusion is configured to include: a front wall, which is opposite to the rear end of the engine hood; and a rear wall, which is opposite to the windshield wiper, wherein the tilt angle of the rear wall is greater than the tilt angle of the front wall.

[0011] In the fairing component involved in technical solution 3, the inclination angle of the front wall of the protrusion is relatively small, thus enabling the driving air to be smoothly guided upwards. Furthermore, the inclination angle of the rear wall of the protrusion is relatively large, thus suppressing the driving air from being guided downwards along the protrusion.

[0012] According to the fairing component involved in technical solution 4, in technical solution 3, the rear wall of the protrusion is inclined relative to the vehicle width direction in a planar view with a constant distance from the wiper.

[0013] In the fairing component involved in technical solution 4, the rear wall of the protrusion is inclined in a manner that is constant with respect to the distance between the wiper and the vehicle's front-to-back direction. Therefore, even when the wiper is configured to be inclined relative to the vehicle's width direction, it can effectively suppress the impact of driving wind on the wiper.

[0014] According to the fairing component involved in technical solution 5, in any one of technical solutions 1 to 4, the protrusion is integrally formed with the main body by resin.

[0015] In the fairing component involved in technical solution 5, the main body and the protrusion are integrally formed. Therefore, compared with the structure in which the protrusion is made as a separate part, there is no height difference at the boundary between the main body and the protrusion, and the driving wind can be smoothly guided to the protrusion.

[0016] As explained above, the fairing component according to the present invention can effectively suppress the impact of driving wind on the windshield wipers. Attached Figure Description

[0017] Hereinafter, with reference to the accompanying drawings, the features, advantages, and technical and industrial significance of exemplary embodiments of the present invention will be described, in which the same reference numerals denote the same elements, and wherein:

[0018] Figure 1 This is a top view showing the main part of a vehicle to which the fairing component involved in the embodiment is applied.

[0019] Figure 2 It means along Figure 1 A sectional view of the state of 2-2 wire cutting.

[0020] Figure 3This is a top view showing the main part of a vehicle that uses the fairing component involved in the first variation.

[0021] Figure 4 This is a cross-sectional view showing the main part of the fairing component involved in the second variation. Detailed Implementation

[0022] The vehicle V, in which the fairing component 10 according to the embodiment is applied, will be described with reference to the accompanying drawings. In the figures, arrows FR, UP, and RH represent the forward, upward, and rightward directions of the vehicle V, respectively. In the following description, unless otherwise specified, the terms front-back, up-down, and left-right directions refer to the front-back direction of the fairing component, the up-down direction of the fairing component, and the left-right direction (width direction) of the fairing component, respectively.

[0023] Figure 1 This is a top view showing the main parts of a vehicle that utilizes the fairing components described in the embodiment. Furthermore, Figure 2 It means along Figure 1 A sectional view showing the state of being cut along line 2-2. For example... Figure 1 and Figure 2 As shown, an engine hood 12 is provided at the front of a vehicle V that uses the fairing component 10 according to this embodiment.

[0024] The engine hood 12 is a panel-shaped component that extends along the width and longitudinal direction of the vehicle and covers the power unit compartment of the vehicle V from above. It is made of metal or resin. In this embodiment, as an example, the engine hood 12 is formed by joining the outer edges of two metal plates through a crimping process.

[0025] A windshield 14 is provided on the rear side of the vehicle, above the engine hood 12. The windshield 14 is a window glass formed by a glass panel that divides the interior and exterior of the vehicle, and the upper part of the windshield 14 is connected to the roof.

[0026] Here, a fairing component 10 is provided between the engine hood 12 and the windshield 14. For example... Figure 2 As shown, the fairing component 10 is disposed at the lower part of the windshield 14 and extends along the width direction of the vehicle. Furthermore, the fairing component 10 is composed of a main body 20 and a protrusion 22. In this embodiment, the main body 20 and the protrusion 22 are integrally formed of resin, but this is not a limitation. For example, the protrusion 22 may be formed separately from the main body 20.

[0027] like Figure 1As shown, a windshield wiper 16 is mounted on the main body 20 of the fairing component 10. The windshield wiper 16 is configured to include a wiper arm 16A and a wiper blade 16B, with one end of the wiper arm 16A rotatably mounted on the main body 20.

[0028] A motor (not shown) is provided at the connection between the wiper arm 16A and the main body 20. Driven by the motor, the wiper arm 16A swings in the vehicle width direction at a predetermined cycle.

[0029] A wiper blade 16B is mounted on the front end of the wiper arm 16A, and the wiper blade 16B abuts against the windshield 14. Furthermore, the wiper blade 16B is constructed from elastic components such as rubber, and moves on the windshield 14 as the wiper arm 16A swings. In this invention, "wiper" refers to a concept that includes both the wiper arm 16A and the wiper blade 16B.

[0030] In addition, Figure 1 The diagram shows the wiper arm 16A and wiper blade 16B in their non-operating state when the wiper 16 is not in use. Furthermore, in this embodiment, as an example, a pair of left and right wipers 16 are provided, but it is not limited to this. For example, a structure with only one wiper 16 may also be used.

[0031] like Figure 2 As shown, the front end of the main body 20 supports the rear end of the engine hood 12 via a sealing member 24. Furthermore, a protrusion 22 protrudes upward from the central portion of the main body 20 in the vehicle longitudinal direction.

[0032] The protrusion 22 is located in the main body 20 at a position further forward of the vehicle than the windshield wiper 16, and protrudes further upward of the vehicle than the rear end of the hood 12. Furthermore, in a planar view, the protrusion 22 is opposite the entire area of ​​the windshield wiper 16 in its non-operating state in the longitudinal direction of the vehicle. In this embodiment, as an example, the protrusion 22 extends from one end of the main body 20 in the vehicle width direction to the other end (see reference). Figure 1 ).

[0033] The protrusion 22 is formed by a front wall 22A and a rear wall 22B. The front wall 22A faces the front of the vehicle in the protrusion 22 and is opposite to the rear end of the hood 12 in the longitudinal direction of the vehicle. The rear wall 22B faces the rear of the vehicle in the protrusion 22 and is opposite to the windshield 14 and the windshield wiper 16 in the longitudinal direction of the vehicle.

[0034] In this embodiment, the protrusion 22 is configured such that the inclination angle of the rear wall 22B is greater than the inclination angle of the front wall 22A. The inclination angle referred to here is the inclination angle of the protrusion 22 relative to the main body 20. The larger the inclination angle, the closer it is to being perpendicular to the main body 20.

[0035] effect

[0036] Next, the function of the fairing component involved in this embodiment will be explained.

[0037] like Figure 2 As shown, the fairing component 10 of this embodiment has a main body 20 at the lower part of the windshield 14. The main body 20 extends along the width direction of the vehicle and is equipped with a windshield wiper 16.

[0038] Furthermore, a protrusion 22 is provided in the main body 20 at a position further forward of the vehicle than the windshield wiper 16, and the protrusion 22 protrudes further upward of the vehicle than the rear end of the hood 12. As shown by the arrow in the figure, the driving wind flowing along the hood 12 impacts the protrusion 22 and is directed upward, thus suppressing the driving wind from impacting the windshield wiper 16.

[0039] And, as Figure 1 As shown, the protrusion 22 is positioned opposite the entire area of ​​the non-operating windshield wiper 16 in the vehicle's longitudinal direction from a planar view. Therefore, in the entire area where the windshield wiper 16 is located, the windshield wiper can impact the protrusion 22 and flow upwards. In particular, in this embodiment, the protrusion 22 extends from one end to the other in the vehicle's width direction, thus preventing the windshield wiper 16 from impacting the windshield wiper 16 by flowing in through the gap in the protrusion 22 in the vehicle's width direction.

[0040] Furthermore, in this embodiment, such as Figure 2 As shown, the inclination angle of the front wall 22A of the protrusion 22 is relatively small, thus enabling the driving air to be smoothly guided upwards. Furthermore, the inclination angle of the rear wall 22B of the protrusion 22 is relatively large, thus suppressing the driving air from being guided downwards along the protrusion 22.

[0041] That is, when the tilt angle of the rear wall 22B is set to the same degree as that of the front wall 22A, the driving air may sometimes be directed downward along the protrusion 22 due to the Coanda effect. In contrast, in this embodiment, the tilt angle of the rear wall 22B is set to be approximately perpendicular to the main body 20, so that the driving air can be effectively directed away from the protrusion 22.

[0042] Furthermore, in this embodiment, the main body 20 and the protrusion 22 are integrally formed from resin. Therefore, compared with a structure in which the protrusion 22 is configured as a separate part, there is no height difference at the boundary between the main body 20 and the protrusion 22, and the driving wind can be smoothly guided to the protrusion.

[0043] In addition, in this embodiment, such as Figure 1 As shown, the shape of the protrusion 22 is approximately arc-shaped from a planar view, but it is not limited to this. For example, it can also be... Figure 3The structure of the first modified example shown. Furthermore, in this embodiment, as... Figure 2 As shown, the rear wall 22B of the protrusion 22 is formed substantially perpendicular to the main body 20, but it is not limited to this. For example, it may also be used... Figure 4 The structure of the second modified example is shown. Furthermore, in the first and second modified examples connected below, structures identical to those in the embodiment are labeled with the same symbols, and descriptions are omitted where appropriate.

[0044] First variation

[0045] Figure 3 This is a top view showing the main parts of a vehicle in which the fairing component 30 involved in the modified example is applied. Additionally, in Figure 3 In the illustration, the fairing component 30 is shown in gray to make it easy to understand its shape.

[0046] like Figure 3 As shown, the fairing component 30 involved in this modified example is composed of a main body 32 and a protrusion 34. The main body 32 is disposed at the lower part of the windshield 14 and extends along the width direction of the vehicle, and a windshield wiper 16 is mounted thereon.

[0047] The protrusion 34 is located in the main body 32 at a position further forward of the vehicle than the windshield wiper 16, and protrudes further upward of the vehicle than the rear end of the hood 12, and is opposite to the entire area of ​​the windshield wiper 16 in the longitudinal direction of the vehicle in a planar view.

[0048] In this modified example, the protrusion 34 is composed of a front wall 34A opposite to the rear end of the engine hood 12 and a rear wall 34B opposite to the windshield wiper 16. The inclination angle of the front wall 34A is the same as that of the front wall 22A of the protrusion 22 in the fairing component 10 of the embodiment, and it is formed into a generally arc shape in a planar view.

[0049] On the other hand, the rear wall 34B is tilted relative to the vehicle width direction in a constant distance from the windshield wiper 16 when viewed from a planar perspective. In this modified example, the rear wall 34B is tilted in a constant distance from the wiper arm 16A of the windshield wiper 16 when viewed from a planar perspective.

[0050] Specifically, the two ends of the rear wall 34B in the vehicle width direction are roughly arc-shaped, similar to the front wall 34A. Furthermore, the portion of the rear wall 34B that is slightly inward in the vehicle width direction than the two ends is inclined in a way that is roughly parallel to the wiper arm 16A in a planar view.

[0051] According to this modified example, the rear wall 34B of the protrusion 34 is inclined in a manner that maintains a constant distance from the windshield wiper 16 in the vehicle's longitudinal direction. Therefore, even when the windshield wiper 16 is configured to be inclined relative to the vehicle's width direction, it is possible to effectively suppress the impact of driving wind on the windshield wiper 16.

[0052] Second variation

[0053] Figure 4 This is a cross-sectional view showing the main part of the fairing component 40 involved in the second modification. (e.g.) Figure 4 As shown, the fairing component 40 of this modified example is composed of a main body 42 and a protrusion 44. The main body 42 is disposed at the lower part of the windshield 14 and extends along the width direction of the vehicle, and a windshield wiper 16 is mounted thereon.

[0054] The protrusion 44 is located in the main body 42 at a position further forward of the vehicle than the windshield wiper 16, and protrudes further upward of the vehicle than the rear end of the hood 12, and is opposite to the entire area of ​​the windshield wiper 16 in the longitudinal direction of the vehicle in a planar view.

[0055] In this modified example, the protrusion 44 is composed of a front wall 44A opposite to the rear end of the engine hood 12 and a rear wall 44B opposite to the windshield wiper 16. The inclination angle of the front wall 44A is the same as that of the front wall 22A of the protrusion 22 in the fairing component 10 of the embodiment, and it is formed into a generally arc shape in a planar view.

[0056] On the other hand, the tilt angle of the rear wall 44B is greater than 90 degrees. Therefore, the rear wall 44B is tilted to the rear of the vehicle relative to the main body 42.

[0057] According to this modified example, the rear wall 44B of the protrusion 44 in the fairing component 40 has an inclination angle greater than 90 degrees, thus reliably suppressing the driving wind flowing from the front of the vehicle to be guided downward along the rear wall 44B.

[0058] The fairing component of the present invention has been described above, but it can naturally be implemented in various ways without departing from the spirit of the invention. For example, in the above embodiments, such as Figure 1 As shown, the protrusion 22 of the fairing component 10 extends from one end of the main body 20 in the vehicle width direction to the other end, but it is not limited to this and may be provided only in a part of the main body 20. Even in this case, the same effect can be obtained by providing a protrusion in a position opposite to the entire area of ​​the non-operating windshield wiper 16 in the vehicle longitudinal direction from a planar view. However, from the viewpoint of making the airflow uniform, it is preferable to have a structure in which the protrusion is provided from one end of the main body to the other end.

[0059] Furthermore, in the above embodiment, the front wall 22A of the protrusion 22 is formed into a generally arc shape from a planar view, but it is not limited to this. For example, the front wall may also be formed into a generally straight line in the vehicle width direction.

[0060] Furthermore, in the above embodiment, the protrusion 22 extends from one end to the other in the vehicle width direction and has approximately the same height, but it is not limited to this. For example, only the portion of the wiper 16 in the vehicle's longitudinal direction that is opposite to the non-operating wiper 16 in a planar view may be made higher than the other portions.
