Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an air flap for an automobile.

[Prior art]

Air flaps are installed at important points from the rear door of the automobile to the rear coater of the vehicle body to reduce air resistance during high-speed running. However, there is a problem in that it is necessary to further study the installation place or the shape in order to efficiently provide it.

Various ventilation devices have been devised for vehicle compartment ventilation (see, for example, Japanese Utility Model Publication No. S58-9775), but in general, many ventilation outlets are provided on both sides of the rear window glass.

That is, in FIG. 1, the ventilation outlets 5 are provided on both sides 4 of the rear window glass 3 of the vehicle body 2, but the ventilation passage from the passenger compartment 7 extends from the rear rail (not shown) to the inside of the rear pillar 8. As it is, it reaches the ventilation outlet 5, and there is a problem that ventilation is not performed very efficiently.

Further, so-called chipping occurs in which the pebbles bounced up by running hit the door and the lower part of the vehicle body.

That is, in FIG. 5, the lower part of the rear door 10 and the outer panel 13 of the rear coater part 12 located adjacently behind the rear door 10 are shown.
The pebbles 15 may hit the lower part of and damage both members. Therefore, there is a problem that it is necessary to provide an appropriate chipping receiver.

[Purpose of device]

The present invention provides an automobile air flap that solves all of the above problems.

[Constitution of device]

This invention is to be provided in the vehicle body rear coater part adjacent to the rear door, is made of a resin molded product, is located adjacent to the air flap under the rear end of the rear door, and extends upward so as to be a chipping receiver. An air flap for a vehicle, characterized in that an air outlet is provided on a rear side of a protruding portion outwardly in a vehicle width direction with an inner portion serving as an air passage for a vehicle compartment.

〔Example〕

The details of the present invention will be described below with reference to the embodiment shown in FIGS.

A rear coater section 22 is located adjacent to the rear door 20. On the lower rear end of the outer panel 24 of the rear door 20, an air flap
Fasten 26 (Figs. 1 and 2). Also the rear coater section 22
Outer panel 28, inner panel 29 and rear apron 30
And are formed in combination (FIGS. 2 and 3).

Then, the weather strip 33 is fitted to the joint portion 32 of each panel of the rear coater portion 22, and the inner panel 35 of the rear door 20 when the door is closed is brought into contact with this. At this time, the weather strip 36 fitted to the inner panel 35 is attached to the rear coater section 22.
The outer panel 28 of.

By contacting the weather strips 33 and 36 in this manner, the airtightness of the passenger compartment 38 is maintained, and a gap 40 is formed between the weather strips 33 and 36.

Furthermore, the outer panel 28 and inner panel of the rear coater section 22
An air gap 42 is formed between the air flap 44 and the air gap 29, and an air flap 44 is installed so as to communicate with the air gap 42.

The air flap 44 is a resin molded product, and has an air passage 45,
An air inlet 46, an air outlet 47, and a clip portion 48 are provided, and the air passage 45 is attached to the outer panel 28 by the clip portion 48 and connects to the void 42 through the air inlet 46.

The air flaps 44 project outward in the vehicle width direction, are located adjacent to the air flaps 26 provided on the rear door 20, and are formed so that the outer surfaces of the air flaps 44 are lined up. It's flowing.

Further, the air flap 44 is formed so as to extend upward along the rear coater portion 22 (FIG. 1), and serves as a chipping receiving portion 50.

Ventilation of the passenger compartment 38 is performed as follows. That is, the air in the passenger compartment 38 enters the rear door 20 through the through hole 52 (FIG. 3) provided in the inner panel 35 of the rear door 20, and further enters the void 40 through the through hole 53 provided in the inner panel 35. . Then, from the gap 40, through the through hole 55 provided in the outer panel 28 of the rear coater portion 22, into the gap 42, through the air passage 45 of the air flap 44, the air outlet 47 located on the rear side of the protruding portion.
Is released from the vehicle.

In addition, there is another route as shown below for ventilation of the passenger compartment 38 (Fig. 4). That is, the side sill 59 located below the front door 58 has an outer panel 60 and an inner panel.
61 and 61, and a front floor 63 is further combined with this. Then, the weather strip 65 is fitted to the joint portion 64 of each panel of the side sill 59, and the inner panel 67 of the front door 58 when the door is closed is brought into contact with this. Also, at this time, a weather strip 68 fitted to the inner panel 67.
Are brought into contact with the outer panel 60 of the side sill 59.

In this way, the airtightness of the vehicle interior 38 is maintained by the contact between the weather strips 65 and 68. However, the air in the vehicle interior 38 is transmitted through the through holes 70 provided in the front floor 63 and the transparent air provided in the inner panel 61. Enter into the side sill 59 through the hole 71. The inside of the side sill 59 becomes an air passage, and the rear coater part 22
Since it communicates with the space 42, the vehicle interior 38 is ventilated through these parts.

[Effect of device]

This invention is formed as described above, and the resin-molded air flap 44 to be mounted on the rear coater portion of the vehicle body is located adjacent to the air flap 26 provided at the lower rear end of the rear door, and the outer surface of each is Since they are formed so as to line up, the traveling wind outside the vehicle flows orderly outside thereof, and air resistance during high-speed traveling can be reduced.

Since the air passage for ventilation has a short path from the air intake portion of the passenger compartment to the air outlet 47, the air resistance is small and efficient. Further, the air outlet 47 is located on the rear side of the portion protruding outward in the vehicle width direction, and is opened in the negative pressure portion where the traveling wind outside the vehicle flows in an orderly manner, so that the efficiency of ventilation is significantly enhanced.

Further, since the air flap 44 is a resin molded product and is extended upward along the rear coater portion as a chipping receiving portion to be large in size, even if the pebbles 15 flipped up by running are hit, it may be damaged or rusted. No trouble occurs.

Moreover, this invention has the advantages of the air flap described above.
Since it is achieved by a simple structure around 44, there are advantages that the number of parts and the number of manufacturing steps are reduced, and the manufacturing cost and weight are reduced.
