く排除する必要がある。 In general, in this type of ventilation system, the front end of the vehicle interior ceiling does not have enough dimensions in both the longitudinal and vertical directions, especially in trucks, so it is difficult to efficiently remove rainwater contained in the driving wind in a narrow space. There is a need.

る。 The present invention was devised in view of the above, and includes a roof panel, an atsupa panel with one edge fixed to the front edge of the roof panel and extending in the width direction of the vehicle, one edge forming the opening of the front window, and the other end forming the atsupa panel. A lower panel is fixed to the upper panel and forms a space between it and the upper panel, and the lower panel is inserted into the space and has one end supported by the front of the upper panel, and is opened toward the front of the vehicle to take in the wind while the other end is directed upward. A drain duct is formed in the lower panel and has a bent middle portion, and is spaced apart from and faces the lower surface of the atsupa panel, and has a bent middle portion. It has an air outlet that allows air to flow into the interior of the vehicle, and a drain hole formed on the lower panel that communicates the space with the outside of the vehicle, and the air outlet is directly hit by the air blown from the drain duct on the lower surface of the atsupah panel. The ventilation system for a vehicle is characterized in that it is disposed at a vertical wall portion of the lower panel that is sufficiently far away from the lower panel and is closer to the vehicle interior, and is located at a distance downward from the upper panel.

本考案によれば、雨中走行時に走行風が雨水を

水は、同ダクトの他端が上方に向けて延びている
ため、同ダクトの他端開口に至るまでに効果的に
排除される。 According to the present invention, when driving in the rain, the wind along with rainwater flows into the drainage duct, but since the duct has a bent middle section, the rainwater in the wind flows through the inner wall of the duct. The water flows out of the vehicle through an opening at one end of the drain duct. Furthermore, since the other end of the duct extends upward, rainwater that has passed through the bent portion of the duct is effectively removed by the time it reaches the opening at the other end of the duct. .

しかも、上記ダクトの他端は上記アツパパネル

排出される。 Furthermore, the other end of the duct opens into the space so as to be spaced apart from and opposite to the lower surface of the atsupa panel, and has an air outlet that allows air from the drainage duct to flow into the passenger compartment. ,
A vertical wall portion of the lower panel that is close to the interior of the vehicle, which is sufficiently far away from the part of the lower surface of the Atsupa panel that is directly hit by the wind blown from the other end of the drainage duct, and that is located at a distance downward from the Atsupa panel. Therefore, even if rainwater is discharged from the opening at the other end of the duct along with the running wind, the running wind will spread within the space and change its direction significantly and flow to the outlet, so that the rainwater will be discharged from the opening at the other end of the duct. The water adheres to the lower surface of the upper panel without reaching the air outlet, flows down along the upper panel, and is discharged from the vehicle through the drain hole.

したがつて、車室内天井部の前端部分の極めて
狭い空間において、走行風に含まれる雨水を効果
的に排除できる換気装置を得ることができる。 Therefore, it is possible to obtain a ventilation system that can effectively remove rainwater contained in the running wind in an extremely narrow space at the front end of the ceiling of the vehicle interior.

配設されている。 In the drawings, the roof panel 1 of the vehicle is curved downward at the front of the vehicle body. The atsupa panel 2 has one edge welded to the roof panel 1 and extends in the vehicle width direction, and the lower panel 3 has one edge welded to the reinforcing panel 4 to form the front window opening 5, and the glass 7 is attached via the mounting rubber 6. The other end is welded to the other edge of the upper panel 2. The resin drainage duct 8 is connected to the above-mentioned Atsupa panel 2 and lower panel 3.
It is inserted into the space 9 formed by the upper panel 2, and has one end opened toward the front of the vehicle body, the middle part bent into a hook shape, and the other end extended upward, and the lower surface of the part of the upper panel 2 that extends in a substantially horizontal direction. They are open to face each other. The drain hole 10 is formed by cutting out a part of the lower surface of the drain duct 8 and by the cutout and the lower panel 3. 11 is an air outlet formed in the lower panel 3;
1 is disposed at a vertical wall portion of the lower panel 3 closer to the vehicle interior at a position sufficiently away from the portion of the upper panel 2 that is directly exposed to the wind blown from the draining duct 8.

よつて、雨中走行時走行風は雨水を伴なつて水

出する。 Therefore, when driving in the rain, the wind flows into the drainage duct 8 accompanied by rainwater, but since the duct 8 has a bent part bent at an almost right angle, the rainwater in the wind flows through the duct 8. It hits and adheres to the inner wall, passes through the inner wall, and flows out of the vehicle through the opening at one end of the drain duct 8.

また、水切ダクト８における上記屈曲部を通過
してしまつた雨水は、水切ダクト８の他端が上方
に向けて延びているため、同水切ダクト８の他端
開口に至るまでに効果的に排除される。 In addition, since the other end of the drain duct 8 extends upward, rainwater that has passed through the bent portion of the drain duct 8 is effectively removed before reaching the opening at the other end of the drain duct 8. be done.

れる。 Moreover, the other end opening of the draining duct 8 opens into the space 9 so as to face the lower surface of the upper panel 2, and the outlet 11 through which air from the draining duct 8 flows into the passenger compartment is located on the lower surface of the upper panel 2. The vertical wall portion of the lower panel 3 that is close to the interior of the vehicle is sufficiently far away from the part that is directly hit by the wind blown from the other end opening of the drain duct 8, and is located at a distance downward from the upper panel 3. Therefore, even if rainwater is discharged from the opening at the other end along with the running wind, the running wind spreads within the space 9 and changes its direction significantly and flows to the outlet 11. It is attached to the lower surface of the upper panel 2 without reaching the lower surface of the upper panel 2, flows down along the upper panel 2, and reaches the lower panel 3. Since the lower panel 3 is downward to the left, it flows to the left and drains into the drain hole 10. is ejected from the vehicle.

ネル３が腐食することを防止できるものである。 As a result, water can be drained from the bent part of the drain duct 8 and the lower surface of the upper panel 2, and since the space 9 formed by the upper panel 2 and the lower panel 3 communicates with the outside of the vehicle, the air blown from the drain duct 8 can be used to drain the upper panel. 2
Or the water attached to the lower panel 3 can be removed from the drain hole 1.
It is possible to prevent the upper panel 2 or the lower panel 3 from being corroded by flowing from the 0 to the outside of the vehicle.
