Description

[Detailed Description of the Invention] The present invention improves the structure of the cowl panel portion of an automobile.

Conventionally, a wiper motor for an automobile has been installed in an internal space with a closed cross section formed by a cowl panel and an upper dash panel.

As a result, maintenance and inspection work such as installation and replacement of the wiper motor is difficult, and noise from the motor enters the room from the interior space through the heater outside air inlet formed in the upper dash panel. was there.

In view of these points, the present invention improves the workability of maintenance inspections such as installing and replacing wiper motors, and
It is an object of the present invention to obtain a cowl panel structure for an automobile that prevents the noise of the motor from entering the interior of the vehicle.

The features of the present invention are that the cowl panel and the upper dash panel form a space that is long in the left and right direction and has a closed cross section, and that a ventilator opening is formed in the center of the cowl panel. An auxiliary opening is formed in a portion other than the auxiliary opening, and the auxiliary opening is covered with a lid body to which a wiper motor is fixed on the outer side.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First, the exterior of the car is shown in Figure 1.

In the figure, 1 and 1 are fender panels, 2 is a bonnet, 21 is a ventilator grill provided at the center of the rear end of the bonnet 2, 3 is a cowl panel, 4 is a wiper, 41 is its arm, 42 is the same blade, 5 indicates the front window.

In such a vehicle, the present invention provides cowl panel 3.
This section was improved as shown in Figures 2 onwards.

That is, the cowl panel 3 and the dash panel upper 6 form a substantially rectangular closed cross section, and a space 7 elongated in the left-right direction is formed inside the closed section.

At this time, the cowl panel 3 is generally formed into a roughly L-shaped cross section consisting of the top panel portion and the front panel portion, but in particular,
In the upper panel part, the rear part 31 is connected to the bonnet 2.
The upper surface panel part is formed in a step shape so that it is exposed flush with the upper surface and the front part 32 is hidden by the rear end part of the bonnet 2.

A ventilator opening 71 is formed in the center of the front part 32 in a position corresponding to the ventilator grill 21 of the bonnet 2, and further, on both left and right sides of the opening 71, the cowl panel 3 is opened. Auxiliary openings 72 and 73 are formed across the front part 32 and front panel part 33 of the top panel part, respectively, opening upward and forward.

In this case, one of the auxiliary openings 73 is provided at a position corresponding to the heater outside air outlet 61 provided in the upper dash panel 6, and the other auxiliary opening 72 is provided at a position corresponding to the heater outside air outlet 61 provided in the upper dash panel 6.
It is located symmetrically to the

Reference numeral 62 denotes an introduction tube provided in the outside air introduction hole 61.

Note that 34.34 is a wiper shaft mounting hole, 35... and 36... are lid mounting holes, 37.38 is a reinforcing plate, and 74.75 is a hole for inserting a bonnet hinge (not shown). It shows.

The auxiliary openings 72 and 73 are closed by lids 8 and 9, and one of the lids 8 is attached in an inclined position with respect to the auxiliary opening 72 as shown in FIGS. 4 and 5. A space 22 is formed between the lid 8 and the bonnet 2, and a wiper motor 40 is disposed in the space 22.

In this case, the lid body 8 includes an inclined part 81 parallel to the front window 5, a rising part 82 located on the side part on the side of the ventilator opening 71, a flange part 83, a wiper motor mounting part 84, and a wiper motor mounting bolt hole 85. , the structure is equipped with bolt holes 86 for attaching the cover body, and after attaching the wiper motor 40 with the reduction gear 49 to the outer side of the cover body 8 in advance via a plurality of mounting bolts 87 and gaskets 88, the cover body 8 is attached.
By attaching the wiper motor 40 to the auxiliary opening 72 via a plurality of attachment bolts 89, etc., the workability of attaching the wiper motor 40 can be improved.

In addition, by blocking the space 22 from the space 7 in the cowl panel 3 by the rising part 82 provided on the side of the ventilator opening 71 of the lid 8, the noise of the wiper motor 40 is removed from the space. It can be prevented from entering the indoor side through the portion 7 and the like.

Note that the drive shaft 48 of the wiper motor 40 and the wiper arm 4
1 shaft 43 is connected within the space 7 via arms 45, 47 and a link 46.

44 is a bearing. As shown in FIGS. 6 and 7, the other lid 9 has a top panel portion 91, a front panel portion 92, a side panel portion 93, a flange portion 94, and a lid mounting bolt hole 95. It is attached to the auxiliary opening 73 via a plurality of attachment bolts 96.

In this way, the auxiliary opening 72.73 is closed with the lids 8, 9, but at this time, care is taken not to block the bonnet hinge insertion holes 74, 75 with the lids 8, 9.

By the way, in the above embodiment, the auxiliary openings 72. are arranged symmetrically on both sides of the ventilator opening 71 of the cowl panel 3.
73, but one auxiliary opening 73 is omitted,
The cover body 9 may be formed integrally with the cowl panel 3, and the upper part of the heater outside air inlet 61 may be covered by the cowl panel 3 itself.

However, if the two auxiliary openings 72 and 73 are provided in the cowl panel 3 in a symmetrical arrangement as in the above embodiment, the cowl panel 3 can be used for both left-hand drive vehicles and right-hand drive vehicles. can.

That is, in the drawing, a right-hand drive vehicle is illustrated, and a heater outside air inlet 61 is provided in the left side of the dash panel upper 6 when viewed from the interior, and an auxiliary opening 73 corresponding to this inlet 61 is provided in the lid body 9. The auxiliary opening 72 on the right side when viewed from the interior is closed with the lid 8 that has the wiper motor 17 attached to the outer side. However, in the case of a left-hand drive vehicle, the heater outside air inlet 61 is closed on the dash panel. Since it is provided on the right side of the upper 6 when viewed from the interior, the auxiliary opening 72 on the right side as viewed from the interior is closed with a lid body (not shown) formed symmetrically with the lid body 9, and the left side when viewed from the interior The auxiliary opening 73 may be closed with a lid (not shown) formed symmetrically with the lid 8 and having a wiper motor attached to its outer side.

Thereby, the cowl panel 3 can be used for both right-hand drive vehicles and left-hand drive vehicles, and the mass productivity of the panel 3 can be improved.

As explained above, according to the present invention, an auxiliary opening is provided in the cowl panel, and this auxiliary opening is covered by the lid body fixed to the outer side of the wiper motor, so that it is easy to install the wiper motor. The workability of maintenance inspections such as replacement can be greatly improved.

Furthermore, since the wiper motor is disposed outside the cowl panel, the noise of the wiper motor can be prevented from entering the interior of the vehicle through the space formed by the cowl panel and the upper dash panel.
