Abstract

To restrict wind disturbance caused by a wiper at a lower end of a front windshield without impairing design viewed from a driver.SOLUTION: A vehicle front part structure disclosed in this description comprises: a hood panel 10 covering a front compartment of a vehicle and provided with a recess 11 in an upper surface rear part thereof; and a hood garnish 20 mounted in the recess 11. An upper surface rear part 22 of the hood garnish 20 is inclined such that a rear end thereof is higher than a front end thereof, and an inclination angle thereof is larger than an inclination angle of the upper surface front part 11 of the hood garnish 20. By not inclining an upper surface rear end of the hood panel itself but adopting the hood garnish an upper surface rear end of which is inclined, a folded portion of an outer hood panel is prevented from being located within a driver's visual field (impairing of design is prevented), and wind disturbance caused by a wiper can be restricted.SELECTED DRAWING: Figure 3

Description

The techniques disclosed herein relate to vehicle front structures. In particular, the present invention relates to a structure that suppresses wind turbulence due to the wiper at the lower end of the front windshield without impairing the design from the driver's point of view.

Patent Document 1 discloses a technique of arranging a deflector on the upper surface of a hood panel covering a front compartment of a vehicle. The deflector is a plate arranged in front of the upper surface of the hood panel, which directs the air flow during traveling upward and smoothes the flow toward the front windshield.

Japanese Unexamined Patent Publication No. 2016-688808

The deflector disclosed in Patent Document 1 can suppress the turbulence of the wind from the hood panel to the front windshield, but may impair the design of the vehicle. One of the causes that disturbs the flow of wind is the wiper placed at the lower end of the front windshield. In order to suppress the wind flow due to the wiper, it is conceivable to add an inclination (inclination to the rear) to the rear end of the upper surface of the hood panel to divert the wind flow upward to the wiper. However, the hood panel includes a hood panel outer and a hood panel inner, and the rear end of the hood panel outer is folded downward so as to cover the trailing edge of the hood panel inner. If the upper surface of the hood panel is inclined at the rear, the driver can see the folded part of the hood panel outer, which is not good in design.

In the vehicle front structure disclosed in the present specification, a recess is provided in the upper rear portion of the hood panel, and a hood garnish having an inclined upper surface rear portion is attached to the recess. The rear portion of the upper surface of the hood garnish is inclined so that the rear end is higher than the front end, and the inclination angle thereof is larger than the inclination angle of the upper surface front portion of the hood garnish. By adopting a hood garnish with an inclined upper surface rear end instead of the upper surface rear end of the hood panel itself, the folded part of the hood panel outer does not come into contact with the driver's eyes (damages the design). (Without), the wind turbulence caused by the wiper can be suppressed.

The rear surface of the hood garnish should be high enough to face the wiper. The amount of air that hits the wiper can be reduced. In this case, the rear surface of the hood garnish is visible to the driver, but the rear surface of the hood garnish can be freely formed. Typically, by making the rear surface of the hood garnish a flat surface or a smooth curved surface, the design from the driver's point of view is also improved.

The hood garnish may be provided with a protrusion at the rear end of the lower surface thereof, which projects downward so as to cover the folded portion of the hood panel outer. The folded part of the hood panel outer can be surely hidden.

Details of the techniques disclosed herein and further improvements will be described in the "Modes for Carrying Out the Invention" below.

It is a perspective view of the front part of a vehicle. It is a perspective view of the front part of the vehicle (the hood garnish is separated). It is sectional drawing along the line III-III of FIG. It is sectional drawing of the hood garnish.

The vehicle front structure 3 of the embodiment will be described with reference to the drawings. FIG. 1 shows a perspective view of the front part of the vehicle 2. In the coordinate system of FIG. 1, Fr indicates the front of the vehicle, H indicates the side of the vehicle, and V indicates the upper part of the vehicle. The meaning of each axis in the coordinate system is the same in the following figures.

The hood panel 10 of the vehicle 2 is provided with a recess at the rear portion of the upper surface, and the hood garnish 20 is attached to the recess. The hood garnish 20 is made of a hard resin. As will be described in detail later, the upper surface rear portion 22 of the hood garnish 20 is inclined so that the rear end is higher than the front end, and the inclination angle is larger than the inclination angle of the upper surface front portion 21. The upper rear edge of the hood garnish 20 is higher than the lower end of the front windshield 4, and hides about the lower half of the wiper 30. The hood garnish 20 has a length in the vehicle width direction that can hide the lower half of the wiper 30.

FIG. 2 shows a perspective view of the front part of the vehicle 2 in which the hood garnish 20 is separated. As described above, the recess 11 is provided behind the upper surface of the hood panel 10. The recess 11 reaches the trailing edge of the hood panel 10. In other words, the recess 11 opens toward the front windshield 4. In other words, the recess 11 does not have an inner surface on the side facing the front windshield 4, and the trailing edge of the bottom surface of the recess 11 is exposed to the front windshield 4. Several through holes (described later) are provided on the bottom surface of the recess 11.

As shown in FIG. 2, when the hood garnish 20 is removed, the lower half of the wiper 30 is exposed and a part of the upper surface of the cowl top panel 5 is also exposed.

FIG. 3 shows a cross section taken along the line III-III of FIG. FIG. 3 shows only a cross section around the hood garnish 20. As described above, the hood garnish 20 is attached to the recess 11 provided on the upper surface of the hood panel 10, and the upper surface rear portion 22 has a larger inclination than the upper surface front portion 21.

The inclination of the upper surface rear portion 22 and the upper surface front portion 21 will be described with reference to FIG. FIG. 4 shows a cross section of the hood garnish 20. The straight line HL in the figure indicates a horizontal line. FIG. 4 shows the inclination of the hood garnish 20 when it is attached to the vehicle. Both the upper surface front portion 21 and the upper surface rear portion 22 are inclined so that the rear end is higher than the front end. The inclination angle A2 of the upper surface rear portion 22 with respect to the horizontal direction is larger than the inclination angle A1 of the upper surface front portion 21 with respect to the horizontal direction. In other words, the upper surface rear portion 22 of the hood garnish 20 is inclined so that the rear end is higher than the front end, and the inclination angle A2 is larger than the inclination angle A1 of the upper surface front portion 21.

Due to the difference in the inclination angle of the hood garnish 20, the rear surface 24 of the hood garnish 20 faces the wiper 30. The position of the trailing edge of the hood garnish 20 is so high that the rear surface 24 faces the wiper 30. The thick arrow line in FIG. 3 indicates the air flow during traveling. As shown by the thick arrow line in FIG. 3, the air flow changes upward at the rear portion 22 of the upper surface, and the air volume toward the wiper 30 decreases. Since the amount of air toward the wiper 30 is reduced, the wind turbulence caused by the wiper 30 can be suppressed.

A resin-made conical protrusion 29 is provided on the lower surface of the hood garnish 20. A small recess 17 is provided on the bottom surface of the recess 11 so as to face the protrusion 29. A through hole 16 is provided on the bottom surface of the small recess 17. In the hood garnish 20, the protrusion 29 on the lower surface fits in the small recess 17, and the tip of the protrusion 29 fits into the through hole 16 and is fixed to the hood panel 10. In addition to the through hole 16, a drain hole 15 is provided on the bottom surface of the recess 11. The drain hole 15 also penetrates the hood panel 10 (hood panel outer 13).

The hood panel 10 includes a hood panel inner 12 that covers the front compartment FC and a hood panel outer 13 that covers the hood panel inner 12 from above. The upper surface of the hood panel outer 13 is a surface that can be seen from the outside. The front compartment FC means a space in front of the dash panel 6.

As shown in FIG. 3, the rear end of the hood panel outer 13 is folded downward so as to cover the trailing edge 12a of the hood panel inner 12. Reference numeral 13a indicates a folded portion (folded portion 13a) at the rear end of the hood panel outer 13.

A protrusion 23 projecting downward is provided at the rear end of the lower surface of the hood garnish 20, and the protrusion 23 covers the folded-back portion 13a of the hood panel outer 13. Therefore, as shown in FIG. 3, the driver DV seated in the driver's seat can visually recognize the rear surface 24 of the hood garnish 20, but the folded-back portion 13a at the rear end of the hood panel outer 13 is formed on the protrusion 23. I can't see it because it's blocked. As described above, in the vehicle front structure 3 of the embodiment, instead of lifting the rear end of the hood panel 10 high, the hood panel 10 is provided with a recess 11, and the hood garnish 20 having a high rear end is provided in the recess. Install. With such a structure, the wind turbulence caused by the wiper 30 can be suppressed without impairing the design (without making the folded-back portion 13a visible to the driver DV).

The points to be noted regarding the technique described in the examples will be described. In the vehicle front structure 3 of the embodiment, the upper surface front edge of the hood garnish 20 is flush with the upper surface of the hood panel 10 immediately before the upper surface. In terms of air flow, it is preferable that the front edge of the upper surface of the hood garnish 20 is flush with the upper surface of the hood panel 10, but the front edge of the hood garnish 20 is higher than the upper surface of the hood panel. May be low.

The rear surface 24 of the hood garnish 20 may be flat or may have a gentle curved surface. When the hood garnish 20 is viewed from above, the rear surface 24 is curved along the curve of the front edge of the front windshield 4.
