Description

[Detailed explanation of the idea] This invention relates to an outside air introduction device for an automobile.

Among automobiles, there is a type of automobile called a cab-over type in which the driver's seat is located at the very front of the vehicle body. In this case, a window hole is provided in the front wall of the vehicle body to serve as an intake port for introducing outside air into the vehicle interior, and a car heater duct is connected to this window hole. When installing a window hole in the front wall of the car body, rainwater will enter the passenger compartment unless a water shield plate is installed inside the window hole, so the water shield plate is connected. The structure becomes complicated and manufacturing costs become high.

This idea is an improvement based on these points.
Embodiments of the present invention shown in the drawings will be described below.

A housing 3 whose rear side is open on the back side of a front bumper 1 and a window hole 2 is provided on the lower side is connected to the front bumper 1. If the bumper 1 is made of steel plate, the casing 3 is separately press-formed and welded, and if the bumper 1 is made of synthetic resin, the casing 3 is
are integrally molded. Then, the rear side of the casing 3 of the bumper 1 is brought into close contact with the opening hole 5 provided in the front surface of the vehicle body 4 by sandwiching the packing seal 6, and the bumper 1 is attached to the front surface of the vehicle body 4. In that case, a screw hole 7 may be provided in the side surface of the casing 3 to serve as an attachment portion for a stay 8 connected to the vehicle body 4. An outside air introduction duct 10 of a car heater 9 is connected to the inside of the opening hole 5 of the vehicle body 4 with a packing seal 11 interposed therebetween.

The effect will be explained.

Outside air enters the casing 3 through a window hole 2 provided on the lower side of the casing 3, passes through an opening 5 in the vehicle body 4, and is drawn into an outside air introduction duct 10 to ventilate the vehicle interior.

Since the window hole 2 faces downward, even if water enters, it will fall downward, and water can be prevented from entering the opening hole 5 of the vehicle body 4. In addition, the housing 3 is
It helps to reinforce the bumper 1 and can also serve as an attachment part.

As explained above, this idea connects a housing with an opening on the rear side and a window hole on the bottom side to the back of the front bumper, aligns the housing with the opening hole in the car body, and then attaches the bumper to the front side of the car body. Since the outside air introduction duct is connected to the inside of the opening in the vehicle body, the window can be directed downward and water can be prevented from entering. and,
The casing can serve as reinforcement for the bumper and increase the rigidity of the bumper, and the casing can also serve as an attachment part when attaching the bumper to the vehicle body.
The number of parts can be reduced and manufacturing costs can be reduced.
