Description

Description: TECHNICAL FIELD The present invention relates to a structure of a rain gutter provided on a side edge of a front window of a vehicle.

(Prior Art) Generally, in a front window structure of a vehicle, a peripheral edge of the front window glass is fixed to a window frame of a vehicle body with an adhesive, and a molding is mounted so as to cover a gap therebetween. (See Japanese Utility Model Application Laid-Open No. 61-198111). Further, a rain gutter may be provided on a side edge of the front window glass (a portion fixed to a front pillar forming a window frame) to prevent rainwater or the like wiped off by a wiper from splashing sideways.

(Problems to be solved by the invention) By the way, as one of the noises generated while the vehicle is traveling,
There is aerodynamic noise generated due to the flow of air in the side windows of the vehicle body. As shown in FIG. 4, the air flow in the side window is generated from the side edge of the front window a, that is, near the front pillar b, and from the separation area A with a conical swirling flow and the reattachment line l. It is roughly divided into a reattachment area B accompanied by a flow along the side window surface at the rear. The peeling area A is particularly wide on the upper side of the side window, and according to the result of noise measurement performed by the present inventors, the sound is about 10 dB louder in the peeling area A than in the reattaching area B. It turned out that.

The present invention has been made in view of such a point, and a purpose thereof is to particularly use the above-mentioned rain garter to bring the reattachment line 1 closer to the front pillar b and to remove the peeling area A at the side window portion. Therefore, the aerodynamic noise is reduced.

(Means for Solving the Problems) In order to achieve the above object, a solution for the invention of claim 1 is to provide a rain garter structure for a vehicle, which comprises a rain garter vertically extending along a side edge of a front window,
The width of the rain garter becomes wider toward the upper side, and the end portion on the center side of the rain garter body is provided closer to the center of the front window toward the upper side.

Here, in the second aspect of the present invention, in the first aspect, the outer panel of the front pillar has a first wall portion facing the end surface of the front window glass, and is bent at a substantially right angle from the first wall portion to form the front window. A second wall extending in parallel with a side surface of the glass, wherein the first wall has:
It is assumed that the length from the outer surface side to the second wall portion is set to be larger as going upward of the pillar. Further, in the invention of claim 3, in claim 1 or 2, the height of the concave groove of the rain gutter is set to increase as it goes upward of the pillar.

(Operation) With the above configuration, in the inventions of claims 1 to 3, the width of the rain garter is increased toward the upper side, and the center of the rain garter vehicle body is extended toward the center of the front window toward the upper side. As a result, in the upper part of the front pillar, the separation of the air flow is caused on the front window side, so in the side window part, the reattachment line approaches the front pillar by that much, and the separation area is reduced.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

1 to 3 show a rain gutter structure of a vehicle according to an embodiment of the present invention, wherein 1 is a front window glass, 2 is a roof portion of a vehicle body, 3 is a window glass of a side door, and 4 is a front pillar. The front pillar 4 has a closed section formed by the outer panel 5 and the inner panel 6, and the closed section is partitioned by a reinforcement 7.

The outer panel 5 of the front pillar 4 has a first wall portion 5a facing the end face of the front window glass 1 and is bent from the first wall portion 5a at substantially right angles inward of the opening, and is parallel to the side surface of the front window glass 1. Extending second wall
5b. The second wall portion 5b is overlapped with the inner panel 6 and the reinforcement 7 and joined by welding, and a side edge of the front window glass 1 is provided on the second wall portion 5b with an adhesive 8 therebetween. It is fixed.

Here, FIG. 2 is a cross-sectional view of a lower portion of the front pillar 4 and FIG. 3 is a cross-sectional view of an upper portion of the front pillar 4. And, as you can see by comparing these two figures,
The length L of the first wall portion 5a from the outer surface side to the second wall portion 5b gradually increases toward the upper part of the pillar (L1 <
L2).

A molding 9 is mounted between the first wall portion 5a and the end surface of the front window glass 1 so as to cover the gap, and is formed integrally with or separately from the molding 9 outside the molding 9. Rain girder 10 is the front pillar 4
Are provided extending vertically. The rain garter 10 has a groove 11 along the surface of the front window glass 1, and receives rainwater or the like wiped by a windshield wiper into the groove 11.

In the rain garter 10, the thickness d of the portion 10a corresponding to the bottom of the concave groove 11 is set to be substantially equal (d1 ≒ d2) over the entire length of the rain garter 10 (that is, the vertical direction of the front pillar 4). The width B of the outer surface portion 10b of the rain girder 10 and the depth D of the concave groove 11 gradually increase toward the upper part of the pillar (B1 <B2, D1 <D).
2), and the outer surface portion 10b has a substantially inverted triangular shape such that the center end of the rain garter vehicle body on the center side is located closer to the center of the front window glass 1 as it goes upward of the pillar. The height H of the concave groove 11 is equal to the first wall 5a.
The height of the girder 10 is set so as to gradually increase (H1 <H2) in accordance with the change in the length L of the front pillar outer panel 5 over the entire length thereof. And are provided so as to be substantially flush with each other.

Therefore, in the above embodiment, the rain garter 10
The outer surface portion 10b of the rain garter 10 is positioned such that the lateral width B of the outer surface portion 10b of the rain garter 10 is increased toward the upper side of the front pillar 4 and the center end of the rain garter body is located closer to the center of the front window glass 1 as the upper side thereof is directed upward. Due to the extension, the air flow is separated on the upper side of the front pillar 4 on the front window glass 1 side, and the reattachment line 1 approaches the front pillar 4 on the side of the vehicle body (the window glass 3 of the side door). The separation area is reduced, and as a result, aerodynamic noise can be reduced.

(Effect of the Invention) As described above, according to the vehicle rain garter structure of the first to third aspects of the present invention, the reattachment line in the side window portion can be formed by a simple structure in which the width of the renata is increased toward the upper side. Since the separation area can be reduced by approaching the front pillar, the aerodynamic noise can be reduced, and the effect is excellent in practicality.
