Abstract

PURPOSE:To improve the degree of freedom of shaping a window panel by mounting a drive for rocking a wiper arm on a hood located in front of the window panel. CONSTITUTION:A wiper 20 is arranged in a position located in front of the hinge center line H of a hood 11 located in front of a window panel F and in a position where the hinge center line H of the hood 11 serves as a fulcrum and no trouble occurs to opening and closing operation. A plate 15 rotatably holding a wiper shaft 14 and a drive 16 are mounted on the under surface of a hood inner panel 13 composing the hood 11. The motor 16 and the wiper shaft 14 are intercoupled to each other through a link mechanism 17. This constitution eliminates a member related to the wiper 20 in an air box 30 and improves the degree of freedom of shaping the window panel.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a wiper mounting structure for a wiper for wiping a window panel.

"Prior Art" Conventionally, a structure in which a wiper for wiping a window panel is attached to an air box has been known.

An example of the structure of such installation is shown in Fig.
130983), and in FIG. 4, 1 is an air box formed at the lower end of the window panel 2 in a closed cross-sectional shape along the vehicle width direction, and this is connected to the dash upper panel 3 and the cowl top panel. It consists of 4th grade. A wiper shaft 5 is attached to the top plate portion 4a of the cowl top panel 4, and a wiper arm 6 is installed inside the air box 1 by reciprocating the wiper shaft 5 by a predetermined angle.
A link machine #18 that swings the is provided. 9 is a hood, and S is a sealing member.

A drive motor (not shown) is provided in the air box 1, and when this drive motor is driven, the wiper shaft 5 reciprocates by a predetermined angle via the link mechanism 8, which causes the wiper arm 6 to swing. Wiping of the window panel 2 is performed.

Furthermore, as for this kind of structure, for example,
There are those described in Japanese Utility Model Publication No. 76480, Japanese Utility Model Application Laid-open No. 62-10818, and the like.

[Problems to be Solved by the Invention] In recent years, in order to improve the degree of freedom in shaping the window panel, there has been a trend to place the front end of the window panel as far forward as possible.

On the other hand, in order to prevent fog formation on the inner surface of the window panel 2 during the winter season, etc., it is necessary to configure the window panel so that warm air blown from the def duct is blown onto the inner surface of the window panel. For this reason, even when the front end of the window panel is placed as far forward as possible, it is necessary to move the defer duct to the front as well.

However, in the conventional wiper mounting structure, the link mechanism 8 and the like are provided in the air box 1, so a space must be secured in the air box 1 in which the link mechanism 8 can be operated. For this reason, the rear side wall 3a of the air box 1 could not be placed in the front position as shown by the broken line, and the differential duct (not shown) at the rear of the side wall 3a could not be placed forward. .

Therefore, there was a problem in that the window panel 2 could not be placed forward, and the degree of freedom in shaping the window panel 2 could not be improved.

[Purpose of the Invention This invention has been made in view of the above problems,
The purpose of this invention is to provide a structure for installing a wiper on an automobile, which can improve the degree of freedom in shaping the window panel.

[Means for Solving the Problem] In order to achieve the above object, the present invention includes a wiper arm, a wiper shaft to which the wiper arm is attached, and a link mechanism that rotates the wiper shaft to swing the wiper arm. It is characterized in that the drive motor is attached to the hood provided in front of the window panel.

[Operation] Since the wiper shaft and the drive motor are attached to the hood, there is no need to secure space in the air box for operating the link mechanism, and therefore the rear side wall of the air box is placed forward. can do.

[Example] Hereinafter, an example of the structure of the wiper installation for an automobile according to the present invention will be described based on the drawings.

In FIG. 1, 11 is a hood provided in front of the window panel F, which is the hood outer panel 1.
2, a hood inner panel 13, etc., and the hood outer panel 12 and the hood inner panel 13 form a closed cross section. A base plate 15 rotatably holding a wiper shaft 14 and a drive motor 16 are attached to the lower surface of the hood inner panel 13. W is a weld nut.

A link mechanism 17 is attached to the wiper shaft 14, and when the drive motor 16 is driven, the wiper shaft 14 reciprocates by a predetermined angle via the link mechanism 17. Further, a wiper arm 21 of the wiper 20 is attached to the tip of the wiper shaft 14, and the wiper arm 21 swings as the wiper shaft 14 reciprocates.

When the wiper 20 is in the set position (the storage position of the wiper 20), it is set to be located forward of the hinge center line H of the hood 11, as shown by the solid line in FIGS. 1 and 2. has been done. Further, the hinge center H is set to be on the upper surface side of the window panel F.

When the hood 11 opens and closes using the hinge center line H as a fulcrum, the wiper 20 does not interfere with the opening and closing operation.

In addition, as shown in FIG. 3, when the hood 11 is pulled, the hood lock release lever (not shown) located inside the passenger compartment (not shown) releases the hood lock primary ~P, about 20 mm away.
It is designed to float. And radiator core 2
3, a microswitch 24 that detects the floating of the hood 11
is attached, and when the microswitch 24 detects the floating of the hood 11, it stops the operation of the wiper 20 if the wiper 20 is operating and moves the wiper 20 to the set position. . Thereby, even if the hood 11 is opened when the wiper 20 is activated, the wiper 20 does not become an obstacle.

Further, in FIG. 1, numeral 30 is an air box formed in a closed cross-sectional shape along the vehicle width direction at the lower end side of the window panel F. It consists of 33 panels. The dash upper panel 31 forms a bottom portion 31a of the air box 30 and a rear side wall portion 31b. 34 is an engine, 35 is a heater unit,
36 is a differential duct for blowing air toward the window panel F, 37 is a harness, and 38 and 39 are seal members.

As mentioned above, since the drive motor 16 and the link mechanism 17 for swinging the wiper 20 are not disposed inside the air box 30, there is no space inside the air box 30 for operating the link mechanism 17. There is no need to secure a space for arranging the drive motor 16, etc. Therefore, the rear side wall portion 31b of the air box 30 can be extended forward, and the cross-sectional area of the air box 30 can be reduced as shown in FIG. Can be made smaller. Thereby, the differential duct 36 and the window panel F can be arranged largely forward, and the degree of freedom in shaping the window panel F can be improved.

Furthermore, since the drive motor 16 is mounted outside the air box 30, the operating noise of the drive motor 16 is prevented from being directly transmitted into the vehicle interior, making the interior of the vehicle quiet.

[Effects] As explained above, according to the present invention, the wiper shaft and the drive motor are attached to the hood.
There is no need to secure space in the air box for the link mechanism to operate, and therefore the rear side wall of the air box can be placed forward, which allows the window panel to be placed far forward, allowing the window to move forward. It is possible to improve the degree of freedom in shaping the panel.

Furthermore, since the drive motor is mounted outside the air box, the operating noise of the drive motor is prevented from being transmitted directly into the vehicle interior, making the interior of the vehicle quiet.
