Description

  The present invention relates to a windshield structure that is positioned on the front side of a vehicle and ensures a driver's field of view.

2. Description of the Related Art Conventionally, a windshield structure in which a lower side of a vehicle windshield (front glass) is shielded by a liquid crystal panel is known (for example, see Patent Document 1). This windshield structure reduces the light transmittance of the liquid crystal panel when the vehicle is traveling. In such a windshield structure, the movement range of the line of sight of the driver who drives the vehicle is limited to a region above the light-shielded liquid crystal panel. As a result, this windshield structure limits the movement range of the driver's line of sight, so that fatigue caused by the driver's visual stimulus can be reduced.
However, in this windshield structure, the present inventors have confirmed through experiments described later that the driver's line of sight is scattered vertically in the region above the windshield. That is, the windshield structure has a problem that the line of sight of the driver during driving is scraped upward from the vicinity of the road surface to be watched.
On the other hand, it is a windshield structure conventionally provided with a display means for displaying a driver's visual target on the windshield, and the display means is controlled so that the intersection between the traveling direction of the vehicle and the horizon is the visual target. The thing is proposed (for example, refer patent document 2). In this target display device, since the driver drives the vehicle while directing his / her line of sight toward the visual target displayed on the windshield, the driver's line of sight is stabilized.

Embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
FIG. 1 referred to here is a configuration explanatory view of the windshield structure according to the first embodiment, and shows a state in which the windshield structure is looked down from diagonally above the front of the vehicle. FIG. 2 is a schematic view showing a state in which the driver sees the windshield structure of FIG. 1 from the seating position. FIG. 3 is a side view showing the arrangement of the human body model for defining the seating position of the driver, as seen from the left side surface of the vehicle. Incidentally, here, a case where the vehicle is in contact with a horizontal road surface will be described.

  As shown in FIG. 1, the windshield structure 1 a according to the first embodiment is positioned on the front side of the driver D in the vehicle V to ensure the visibility of the driver D, and includes the windshield 2 (also referred to as a windshield). Say).

  The windshield 2 is formed of a transparent glass that is slightly curved so as to protrude from the inside to the outside of the vehicle V, and a pair of glass antennas 5 are arranged on top of the windshield 2 so as to sandwich the room mirror 3 therebetween. Is provided. The glass antenna 5 corresponds to an “antenna” in the claims. The glass antenna 5 in this embodiment is used as a transmission / reception antenna for an in-vehicle radio, a television, a car navigation system or the like, and is formed on the windshield 2 so as to have a predetermined wiring pattern.

  The wiring pattern of the glass antenna 5 in this embodiment is formed in a spiral shape so that the outline of the outer shape in a plan view is substantially rectangular. As will be described below, the lower end 5a of the seating position is It is perceived as a straight line when viewed from the driver D. Incidentally, the wiring pattern of the glass antenna 5 is not particularly limited as long as the lower end 5a can be defined. For example, the wiring pattern of the glass antenna 5 may be formed so that the antenna lines meander, or may be arranged in parallel. The antenna line may be formed by an antenna line orthogonal to the antenna line. Further, the glass antenna 5 may be formed by one antenna line extending substantially horizontally when viewed from the driver D at the sitting position. In this case, the lower end 5a is defined at the position where the antenna line extends. Is done.

The lower end 5a of the glass antenna 5 is substantially curved because the glass antenna 5 is formed on the curved windshield 2 as described above, but the driver D has a substantially horizontal straight line when viewed from the seating position. It is formed to perceive as.
That is, as shown in FIG. 2, the lower end 5a of the glass antenna 5 as seen from the seating position of the driver D is above the horizon Hr and below the room mirror 3, and is parallel to the horizon Hr. It will rest on a straight line L1 that crosses the shield 2.

In this windshield structure 1a, the eye height of the driver D that defines the lower end 5a of the glass antenna 5 is set equal to the eye point height corresponding to the eye height of the driver D of the standard body shape. Has been. That is, the driver D perceives the lower end 5a as substantially horizontal by looking at the lower end 5a of the glass antenna 5 at the position of the eye point, and consciously considers the straight line L1 that is an extension of the lower end 5a of the glass antenna 5. Or you will perceive unconsciously.
In addition, the lower end 5a of the glass antenna 5 in the present embodiment is set to a position above the height of the eye point and below the height of the room mirror 3 as described above.

The eye point is an adult male 50% tile human body specified in JIS D 4607 “3D sitting body model for measuring vehicle interior dimensions (3DM-JM 50)” or ISO 6549 “Road vehicles-Procedure for H-point determination”. It can be set using a model (hereinafter, sometimes simply referred to as “human body model”).
This eye point can be defined as a reference point in the passenger compartment, and specifically, for example, by the method shown in “Attachment 81 of Notification (Ministry of Land, Infrastructure, Transport and Tourism) of the Details of Safety Standards for Road Transport Vehicles”. Can be determined. However, the method of determining the eye point is not limited to this, and may be determined by other methods.
Incidentally, in the first embodiment, as shown in FIG. 3, the human body model 12 is seated on the driver's seat S at a predetermined position by the seating method defined in ISO 6549, and the height Ht of the eye point 10 is set as the human body model. It is set to be 635 mm above the vertical direction from H point 11 (also referred to as DRP (Driver's Reference Point)) which is 12 hip joint points. In FIG. 3, reference numeral 2 denotes a windshield, and reference numeral V denotes a vehicle. In the first embodiment, the torso angle θ1 (also referred to as the back angle) is 25 degrees. When the torso angle θ1 is 25 degrees as described above, the rearward inclination angle θ2 of the eye point 10 is 8 degrees. It has become. The torso angle θ1 is not limited to 25 degrees and can be set as appropriate. In this case, the position of the eye point 10 is determined according to the magnitude of the torso angle θ1. It will be corrected to be a point.

  Next, the effect of the windshield structure 1a according to the first embodiment will be described. 4A referred to here is a schematic diagram showing movement of the line of sight in the windshield structure shown in FIG. 2, and FIG. 4B shows movement of the line of sight in the windshield structure as a comparative example. It is a schematic diagram shown. Note that the line-of-sight trajectories W1 and W2 indicating the movement of the line of sight in FIGS. 4A and 4B are obtained using an eye mark recorder (manufactured by nc, EMR-8).

  In general, when the driver consciously determines a horizontal line of sight at the eye level, the driver sees the scenery outside the vehicle at substantially the same height as the horizon. In other words, in a vehicle that is in contact with a horizontal road surface with good line of sight, the driver's line of sight is determined at the same height as the horizon that appears as a road break in the distance ahead.

  Specifically, for example, as shown in FIG. 4B, in the windshield structure 1r (comparative example) including the windshield 2 ′ not having the glass antenna 5 (see FIG. 2), the driver D (see FIG. 2) sees the horizon Hr while looking at the windshield 2 'with a horizontal line of sight. When the vehicle V having such a windshield structure 1r is driven, the driver D perceives the scenery seen through the windshield 2 'as moving relatively, so that the line-of-sight locus W2 of the driver D becomes the horizon. The inventors of the present invention have confirmed that the light is greatly scattered above and below the windshield 2 ′ with Hr as a boundary. Although not shown in the drawings, the present inventors have confirmed that such scattering of the line-of-sight locus W2 also occurs in a conventional windshield structure that shields the lower side of the windshield with a liquid crystal panel (for example, see Patent Document 1). Has been.

On the other hand, as shown in FIG. 4A, in the windshield structure 1a according to the first embodiment, the driver D (see FIG. 2) at the sitting position perceives the substantially horizontal lower end 5a of the glass antenna 5. As a result, it was found by eye-gaze measurement by the eye mark recorder that the eye-gaze locus W1 of the driver D is mainly concentrated below the horizon Hr.
That is, in the windshield structure 1a according to the first embodiment, unlike the conventional windshield structure 1r (see FIG. 4B) in which the line of sight of the driver D is scattered above the horizon Hr, the lower end of the glass antenna 5 The driver D perceives a straight line L1 on which 5a is placed, that is, a straight line L1 that is above the horizon Hr and extends below the room mirror 3 in parallel with the horizon Hr, so that the line of sight is on the road surface near the horizon Hr. It is thought that it was induced.

  According to the windshield structure 1a according to the first embodiment as described above, the movement of the line of sight of the driver D can be concentrated below the horizon Hr. Therefore, when the driver D drives the vehicle V, the road surface You can pay attention to the top stably.

  Further, according to the windshield structure 1a according to the first embodiment, the movement of the line of sight of the driver D can be concentrated with a simple structure in which the lower end 5a of the glass antenna 5 is adjusted. Unlike a conventional windshield structure that requires means (see, for example, Patent Document 2), an inexpensive manufacturing cost can be realized.

  In addition, according to the windshield structure 1a according to the first embodiment, the driver D at the seating position can perceive the straight line L1 with the full width of the windshield 2, so that the driver D is more surely below the horizon Hr. The movement of the line of sight can be concentrated. And when such a windshield structure 1a is applied to a large vehicle in which the width of the windshield 2 is large, the above-mentioned effect will be exhibited.

  In the windshield structure 1a according to the first embodiment as described above, a pair (two) of the glass antennas 5 is provided above the windshield 2, but the present invention is not limited to this, As long as the lower end 5a can be defined, the number of the glass antennas 5 may be one, or three or more.
