[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof mechanism for doors of large vehicles.

[0002]

2. Description of the Related Art Conventionally, a waist seal is interposed between a door outer plate of a large vehicle and the outside of a window glass to prevent water droplets from entering the door.

[0003]

However, since the window glass is moved up and down when opening and closing, raindrops penetrate from the waist seal and the waterproof effect is insufficient even when the window glass is closed. Therefore, a small window glass for preventing a left-turn accident under the window glass becomes dirty or becomes cloudy with raindrops. In order to prevent this, the window glass is vertically divided into two parts, and the window glass above the small window glass is attached to the window frame of the door so as to be killed. For this reason, the fitted portion of the window glass deteriorates the visibility due to dirt, the confirmation of the rearview mirror is insufficient, and since only half the window glass can be opened, ventilation in the driver's cab is insufficient and habitability is reduced. There were drawbacks such as lack of comfort.

The present invention enhances the airtightness between the waist seal of the door outer plate and the outer surface of the window glass, and detects raindrops by the raindrop detection sensor installed on the outer surface of the waist seal, and the motor installed inside the door by this detection. The blower is actuated, the air pressure inside the door is raised from the outside to prevent raindrops from entering the waist seal portion, and the entire window glass can be integrated into one piece to allow it to move up and down. Improving visibility and livability in the driver's cab, preventing stains and fogging on the small window glass for preventing left-turn accidents, and ensuring driving safety in combination with maintaining the visibility of the rearview mirror through the window glass. It is a device for the purpose.

According to the present invention, the waist reinforcements 3, 4 provided on the inner side 2a of the outer plate 2 of the door 1 and the window glass 6 for moving up and down the window opening 5 of the door 1, and the waist reinforcement. Upper edges 3a, 4a and lower edges 3b, 4 of 3, 4
an air supply passage 9 is formed by the waist seals 7 and 8 attached to b and being in airtight contact with the outer surface 6a of the window glass 6,
A raindrop detection sensor 10 is provided on the outer surface of the upper waist seal 7.
A motor 11 that starts when the raindrop sensor 10 detects a water drop and a blower 12 that sends high-pressure gas to the air supply passage 9 by starting the motor 11 are provided inside the door 1. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 1 is a door which is openably and closably installed in a driver's cab of a truck. The door 1 has an outer plate 2 and an inner plate 13 opposed to each other with a gap substantially equal to the thickness of a window glass 6, Skin 2
A window opening 5 is formed in the upper half of the inner plate 13, and a single window glass 6 is provided on the window opening 5, the outer plate 2 and the inner plate 13 so as to be vertically movable.

On the inner side 2a of the outer plate 2, one waist reinforcement 3 is lined up, and an upper edge 3a and a lower edge 3b are fixed to the outer plate 2. Further, a substantially middle portion inside the waist reinforcement 3 is separated. A window glass 6 for fixing the lower edge 4b of the L-shaped waist reinforcement 4 and moving up and down the upper edge 4a.
Facing the outer surface 6a side.

A waist seal 7 is airtightly fixed to the upper edge 2b of the outer plate 2 and the upper edge 3a of the waist reinforcement 3 along the longitudinal direction. Inside this waist seal 7,
That is, the leg portion 7 having a bifurcated shape is directed toward the outer surface 6a of the window glass 6.
a and 7b are projected along the longitudinal direction of the waist seal 7, and these leg portions 7a and 7b are brought into airtight contact with the outer surface 6a of the window glass 6.

A waist seal 8 is also airtightly fixed to the upper edge 4a of the other waist reinforcement 4 along the longitudinal direction, and the leading edge 8a of this waist seal 8 is attached to the window glass 6.
The outer surface 6a is made to contact airtightly.

The portion surrounded by the two waist reinforcements 3 and 4, the upper and lower waist seals 7 and 8 and the outer surface 6a of the window glass 6 serves as an air supply passage 9.

Further, a raindrop detection sensor 10 is laid along the longitudinal direction on the outer surface of the waist seal 7 provided along the lower peripheral edge of the window opening 5 in the outer plate 2. Between the inside of the door 1, that is, between the outer plate 2 and the inner plate 13, a motor 11 that is started when the raindrop detection sensor 10 detects the attachment of raindrops.
And a blower 12 that discharges high-pressure air when the motor 11 is started. A discharge passage 14 for discharging high-pressure air from the blower 12 communicates with the air supply passage 9.

In the figure, reference numeral 15 is a small window glass for preventing a left turn accident, and 16 is a weather strip which is airtightly provided between the outer plate 2 and the small window glass 15. Reference numeral 17 denotes a waist seal which is airtightly attached to the upper edge 13a of the inner plate 13 along the longitudinal direction.
Is in contact with the inner surface 6a of the window glass 6. A trim pad 18 is attached to the outside of the inner plate 13. Reference numeral 19 shown in FIG. 3 denotes a glass run provided between the outer plate 2 and the inner plate 13 along the left and right side edges of the window glass 6, and the insides 19a and 19a of the glass runs 19 and 19 are windows. The outer surface 6a and the inner surface 6b of the glass 6 are in airtight contact with each other.

Since the present invention is configured as described above, when the raindrop detection sensor detects raindrops during rain or water drops during car wash, a current from a power supply (not shown) flows into the motor to start the motor. The blower also operates and high-pressure air is discharged to the discharge path, and is further sent to the air-supply path communicating with this discharge path to increase the pressure inside the air-supply path. It is possible to prevent the intrusion of water droplets into the interior of the door from both contact portions.

[0014]

As described above, according to the present invention, since raindrops can be prevented from entering the inside of the door, the small window glass below the window glass is prevented from being contaminated or exposed, and accordingly, the window glass is also reduced. Since it is possible to raise and lower the sheets and the transmittance of the small window glass is not inferior, it is possible to ensure a left turn accident prevention, and it is also possible to reliably confirm the rear view through the rearview mirror through the window glass, The driving safety can be improved.
