Description

[Detailed Description of the Invention] a. Field of Industrial Application The present invention relates to a cowl ventilator device for an automobile that draws outside air into a vehicle interior, such as a heater.

b. Conventional technology and its problems Conventionally, in cowl ventilator devices for automobiles, an outside air intake port is provided in the cowl upper panel in front of the front window, and a cowl bench box (outside air intake box) is placed inside the opening. In this system, outside air is drawn into the vehicle interior, such as a heater, while separating air and water. Generally, this cowl bench box 5 (hereinafter abbreviated as box) is installed on the opposite side of the handlebar mounting position (on the right handlebar shown in the figure) by utilizing the dead space below the cowl upper panel 2 as shown in FIG. In the case of a vehicle body, it is attached to the left side).

By the way, the mounting surface of the cowl upper panel 2 is normally upwardly rearward with respect to the longitudinal direction of the vehicle body, and the outlet 13 for discharging air into the passenger compartment is located at the longitudinal end of the box 5. The box 5 is assembled to the vehicle body so that the outlet port 13 is located near the side of the vehicle body. For this reason, the box 5 cannot be simply moved to the opposite side, and a dedicated box corresponding to the left and right handles of the vehicle body is required, which is one of the causes of increased production costs.

Furthermore, when this box 5 is molded from resin, it can be molded freely, but when it is attached to the cowl upper panel a as shown in FIG.
It is necessary to interpose the packing b and provide the box d with an abutting edge c to be in contact with the packing b, and therefore the size of the outside air intake cross section of the box d is subject to restrictions.

On the other hand, if Box 5 is made of steel plate,
Since the cowl upper panel and darts panel can be spot welded, they are not subject to the same restrictions as resin molded products, but they are also subject to drawing processing restrictions, which has the disadvantage of not being able to secure a sufficient outside air intake cross section. be.

c. Means for Solving the Problems The present invention has been made in view of the above circumstances, and aims to eliminate the drawbacks of the above-mentioned prior art and provide a cowl ventilator device that can be used in both left and right hand drive vehicles. It is something.

The gist is that in a cowl bench box of a cowl ventilator device that is attached to the lower surface of a cowl upper panel formed at the front of the front window so as to be inclined rearward, the box is configured to have a substantially rectangular shape in plan view; The box is removably divided into upper and lower halves, the upper edge of the upper box is formed upward to correspond to the slope of the cowl upper panel, and an outlet is provided on one side of the lower box to send air into the passenger compartment. There is provided a cowl ventilator device for an automobile, characterized in that both an upper and lower box are assembled and fixed together.

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

In Figures 2 and 3, 1 is the front windshield, 2 is the cowl upper panel, 3 is the dash panel, 4 is the outside air intake opened in the cowl upper panel 2, and 5 is located inside the outside air intake. It is a box that was made. The box 5 is divided into a cylindrical upper box 10 and a shallow dish-shaped lower box 11, and the upper box 10 is made of a steel plate and is welded and fixed to the cowl upper panel 2 and the dash panel 3 at appropriate positions. The lower box 11 is similarly formed by drawing a steel plate, and the joint 1 between the upper end periphery and the lower end periphery of the upper box 10 is formed.
2, and the joint portion 12 is fixed by welding with a spot or the like. 13 is an air outlet, and 14 is a tube connected to the outlet 13 for sending air into the vehicle interior. In addition, a drain plate is appropriately provided inside.

When only the lower box 11 is molded from resin, packing may be provided at the joint portion 12, and both the upper and lower boxes may be joined together by tightening screws or the like.

FIG. 4 is an explanatory diagram showing a mode in which the device of the present invention is used for both right and left handles. Normally, the cowl upper surface of the box is slanted rearward in the front-rear direction of the vehicle. Therefore, when installing a box at position R for a right-hand drive vehicle and at position L for a left-hand drive vehicle, the upper box 10 of the box 5 is moved and relocated in parallel to the L side as shown by the arrow. The lower box 11 may be rotated by 180 degrees, and both the upper and lower boxes may be fixed by the means described above.

FIGS. 5 and 6 show another embodiment of the present invention, in which numeral 40 denotes an upper box, and a pair of recesses 36 and 36' serving as outside air intakes are provided in the ceiling of the upper box. 37 is a sol sealer provided between the cowl upper panel 2 and the upper box 40; 38 is a packing provided between the upper box 40 and the lower box 41; both boxes are fixed with a plurality of screws 39; be.

When using the box having this configuration, only one of the pair of recesses 36, 36' provided in the upper box 40 is left open. That is, one of the recesses 36 and 36' may be opened and used for both the left and right handles. The rest is the same as in the previous embodiment.

d Effects of the invention According to the invention, the lower box is attached to the upper box so that the outlet provided in the lower box is located closer to the side of the car body depending on the car body of each left and right handle. However, since it can be assembled by changing the direction by 180 degrees, it can be used for both left and right handlebars, reducing production costs.

Furthermore, since the cowl bench box is divided into upper and lower parts, not only deep drawing but also assembly work such as spot welding becomes easier.

Furthermore, compared to models that are integrally molded with resin, the installation space can be used more effectively, reducing the resistance to the passage of outside air.
It can be designed to take in large amounts of outside air. Therefore, when trying to obtain the same performance as the conventional one, there is an effect that the heater fan motor and the heater itself can be made smaller.
