Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a waterproof mechanism for doors of large automobiles.

0002

[Conventional technology]

Conventionally, a waist seal was installed between the door outer panel of large vehicles and the outside of the window glass. This prevents water droplets from entering the inside of the door.

0003

[Problem that the idea aims to solve]

However, since the window glass moves up and down when opening and closing, raindrops can escape from the waist seal. The waterproofing effect is insufficient even when the window glass is closed. For this reason , the small window glass below the window glass that prevents left-turn accidents becomes dirty or fogged up by raindrops. To prevent this, the window glass is divided into two vertically, and the window glass above the small window glass is It is attached tightly to the window frame of the door. For this reason, the part where the window glass is fitted is Visibility deteriorates due to dirt, making it difficult to check the rearview mirror, and the window glass may become damaged. Since it can only be opened halfway, there is insufficient ventilation in the driver's cabin, making it less comfortable. There were defects such as chipping.

0004 This invention improves the airtightness between the waist seal of the door outer panel and the outer surface of the window glass. The raindrop detection sensor installed on the outer surface of the waist seal detects raindrops, This detection activates the motor and blower installed inside the door. By increasing the air pressure from the outside, it prevents raindrops from entering the waist seal area. The whole system can be integrated into a single piece and can be raised and lowered freely, allowing for diagonal front and rear view mirrors. This improves the driver's visibility and the comfort inside the driver's cabin, and also includes small window glass to prevent left-turn accidents. This prevents dirt and fogging, and helps maintain visibility in the rearview mirror through the window glass. This idea was designed to ensure the safety of transportation.

[0005]

[Means to solve the problem] The present invention has waist reinforcements 3 and 4 provided on the inside 2a of the outer panel 2 of the door 1. and a window glass 6 that moves up and down the window opening 5 of the door 1, and waist reinforcements 3 and 4. attached to the upper edges 3a, 4a and the lower edges 3b, 4b and airtightly attached to the outer surface 6a of the window glass 6. An air supply path 9 is formed by the waist seals 7 and 8 that are in contact with each other, and the upper waist seals A raindrop detection sensor 10 is attached to the outer surface of the seal 7, and the raindrop detection sensor 10 detects water. A motor 11 starts when a drop is detected, and high-pressure gas is supplied by starting the motor 11. A blower 12 for sending air to the air passage 9 is provided inside the door 1.

[0006]

【Example】

1 is a door installed in the cab of the truck that can be opened and closed freely, and this door 1 has a window glass. The outer plate 2 and the inner plate 13 are opposed to each other with an interval substantially equal to the wall thickness of the outer plate 6. A window opening 5 is bored in the upper half of the inner panel 13, and the window opening 5, the outer panel 2, and the inner panel 13 are connected to each other. A window glass 6 is provided so that it can be raised and lowered.

[0007] Then, one of the waist reinforcements 3 is lined up on the inside 2a of the outer panel 2, and the upper edge 3a and the lower edge 3b are fixed to the outer panel 2, and the inner side of the waist reinforcement 3 is fixed. The lower edge 4b of another L-shaped waist reinforcement 4 is fixed approximately in the middle, and the upper edge 4a faces the outer surface 6a side of the window glass 6 that is raised and lowered.

[0008] The upper edge 2b of the outer panel 2 and the upper edge 3a of the waist reinforcement 3 are provided in the longitudinal direction. The waist seal 7 is airtightly fixed along the line. The inside of this waist seal 7, i.e. The waist seal 7 has forked legs 7a and 7b facing the outer surface 6a of the window glass 6. The legs 7a and 7b are provided protruding along the longitudinal direction of the window glass 6, and these legs 7a and 7b are attached to the outer surface 6a of the window glass 6. Make airtight contact.

[0009] Also, attach the waist seal 8 to the upper edge 4a of the other waist reinforcement 4 along its length. The leading edge 8a of the waist seal 8 is attached to the outside of the window glass 6. It is brought into airtight contact with the surface 6a.

0010 Then, the two waist reinforcements 3 and 4 and the upper and lower waist seals 7 and 8 The area surrounded by the window glass 6 and the outer surface 6a of the window glass 6 is defined as an air supply path 9.

[0011] Furthermore, the outside of the waist seal 7 attached to the lower peripheral edge of the window opening 5 in the outer panel 2 A raindrop detection sensor 10 is installed along the longitudinal direction on the surface. Inside the door 1, i.e. The raindrop detection sensor 10 detects adhesion of raindrops between the outer panel 2 and the inner panel 13. a motor 11 that starts when the It has a built-in blower 12. A discharge path for discharging high pressure air from the blower 12 14 communicates with the air supply path 9.

0012 In the figure, 15 is a small window glass for preventing left-turn accidents, and 16 is the outer panel 2 and the small window glass. This is a weather strip attached airtightly along between the 17 is the inner plate 13 This waste seal is airtightly attached to the upper edge 13a along the longitudinal direction. The leading edge 17a of the seal 17 is brought into contact with the inner surface 6a of the window glass 6. 18 is inside This is a trim pad attached to the outside of the plate 13. 19 shown in Fig. 3 is the outer panel 2 and inner panel. A glass run is provided along the left and right side edges of the window glass 6 between the plate 13, The inner sides 19a, 19a of the glass runs 19, 19 are the outer surface 6a and the inner surface of the window glass 6. 6b in airtight contact.

[0013] Since the present invention is configured as described above, the raindrop detection sensor detects raindrops or When water droplets are detected during a car wash, current from a power source (not shown) flows to the motor and starts it. At the same time, the blower also operates and releases high-pressure air into the discharge path. The high pressure air is sent to the air passage connected to the window glass, creating high pressure inside the air passage. It also extends to the contact area between the outer surface and the upper waist seal, and the inside of the door is exposed from the contact area between the two. It can prevent water droplets from entering the area.

[0014]

[Effect of the idea]

Therefore, according to the present invention, it is possible to prevent raindrops from entering the inside of the door. The lower small window glass no longer gets dirty or rough, and as a result, the window glass It is also possible to raise and lower the glass as a single piece, which eliminates the problem of poor transmittance of small window glass. Since there is no left turn accident, it is possible to prevent accidents when turning left, and it is also possible to prevent the rear view mirror from looking through the window glass. It is also possible to reliably check the rear visibility, which improves driving safety. .
