Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automobile door structure that forms a door sash above a door body.

(Prior Art) A door sash in a conventional door structure is constructed by integrally forming a sash outer on the outside of the vehicle and an inner sash on the inside of the vehicle, as disclosed in, for example, Japanese Utility Model Application Publication No. 60-81026.

With this type of door structure, when ventilating the inside of the car,
The door window was slightly opened and dirty air was being expelled through the gap.

However, when ventilating by opening the door window, the intrusion of rainwater and mud through the gap can be prevented to some extent by using sun visors, etc., but in heavy rain, when driving on a muddy road, or when stopping in the rain, the intrusion of rainwater and mud can be prevented completely. It was difficult to prevent this.

(Object of the Invention) The present invention was made to solve the above-mentioned problems, and provides an automobile door structure that can completely prevent rainwater, mud, etc. from entering when ventilating the inside of a car. The purpose is to provide.

(Structure of the Invention) The present invention is a door sash that holds a window glass that forms the upper periphery of a patented window opening, which is characterized by the upper edge of a door body, and that blocks the door window opening so that it can be raised and lowered, the door sash is It is formed by joining an outer satsus that forms a plate and an inner satsus that guides the windshield shown in F, and a communication hole is formed in the inner satsus that communicates the interior of the vehicle with the outside of the vehicle and is opened and closed by raising and lowering the windshield. The outer part of the sash 1 is formed with an extending part extending toward the center of the door window opening so as to cover the outside of the vehicle of the communication hole.

According to such a configuration, the part where the inside of the car and the outside of the car communicate has a double structure in which the outside of the car of the communication hole provided in the sash inner is further covered with the sash outer, so that by opening the window glass appropriately, By using the above-mentioned communication part, ventilation can be performed while completely preventing rainwater and mud from entering from the outside.

(Example) Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of an automobile equipped with a door D having a door sash 1 and a window glass 2, and FIG. 2 is a side view of the door D. The door sash 1 forms the upper periphery of a door window opening W whose lower side is the toe edge of the door body, and is configured to hold an E-shaped window glass 2 that closes the door window opening W so as to be able to rise and fall freely.

FIG. 3 is a sectional view of the vicinity of the door sash 1, and in the figure, 3 is a roof rail on the vehicle body side.

This roof rail 3 is formed by an inner roof rail 31 and an outer roof rail 32 that form a closed cross section, and a reinforcement 33 that crosses this closed cross section diagonally. are joined together at their upper and lower ends.

Further, a roof panel 4 is provided to cover the upper part of the roof rail 3. End 4C of this roof panel 4
is made to protrude to the outside of the vehicle, and weather strips 5, 6 are attached to this end 4C and the top end 3a of the roof rail 3.
is installed.

The door sash 1 is formed by joining an outer sash 11 and an inner sash 12 that guides the window glass 2. The outer satchel 11 consists of an outer panel 11a constituting an outer panel and an inner panel 11b bent inward from the outer panel 11a.The lower part of the inner panel 11b extends toward the inside of the vehicle to attach the weather strip 7. A receiving portion 11G for attachment is formed. This weather strip 7 has a lip portion 7a that comes into contact with the outer roof rail 32.

Further, the upper end portion 11d of this outer sash 11 is formed so as to come into contact with the lip portion 5a of the weather strip 5 attached to the roof panel 4 when the door D is closed.

The sash inner 12 has a rail portion 12a which forms a closed cross section and comes into contact with the weather strip 6 when the door D is closed;
A receiving portion 12b extending from this rail portion 12a to the outside of the vehicle
It consists of A glass run 9 for abutting the upper end 2a of the window glass 2 is attached to the window side of the receiving part 12b, and the roof side is joined to the back surface of the receiving part 11C of the sash outer 11.

Furthermore, in the present invention, the end of the receiving portion 12b of the sash inner 12 is extended toward the center of the door window opening W, and the communicating hole 13 is provided in this extended portion. A plurality of communication holes 13 are provided adjacent to each other in the region a shown in FIG. 2 as shown in FIG. 4.

An extending portion 11e extending toward the center of the door window opening W is provided on the outer panel 11a of the sash outer 11 so as to cover the outside of the communication hole 13. At the end of the extending portion 11e, there is a communicating hole 14 that opens toward the door window side, and a protruding portion 1 that is joined directly below the communicating hole 13 of the sash inner 11.
1f is provided, and a weather strip 8 that is in close contact with the outer surface of the window glass 2 is attached to the joint portion between the protrusion 11f and the sash inner 11.

A plurality of the communicating holes 14 are also provided adjacently in the same area as the communicating holes 13, as shown in FIG.

In such a configuration, as shown in FIG. 2, if the door window is opened to a position where the end 2a of the window glass 2 comes into close contact with the weather strip 8, the air inside the vehicle will flow through the communication hole 13 and the communication hole. It can be discharged through 14. In this way, ventilation is performed through the communication hole 13 covered by the extension part 11e of the outer sash 11, and the end 2a of the windshield 2 is in close contact with the windshield 8, so it can be used in case of heavy rain or when the vehicle is parked. But you don't have to worry about rain or mud getting into the cabin.

Note that the range in which the communication hole 13 is provided is not limited to the above, and may be provided depending on the structure of the vehicle body.

(Effects of the Invention) As described above, the present invention provides ventilation in a double-structured part in which the outside of the vehicle of the communication hole provided in the sash inner is further covered with an extension of the sash outer, so that the gap between the windshield and the Rainwater and mud will not enter from the rainwater,
The vehicle interior can be ventilated while completely preventing mud from entering.
