Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ventilation system for a vehicle, and more particularly to a ventilation system for a vehicle in which a rear spoiler is provided along the rear edge of a trunk lid.

[Conventional technology]

In a vehicle, a ventilation hole is provided in the partition wall that separates the passenger compartment from the trunk room, such as a rear tray at the rear of the passenger compartment, to communicate the passenger compartment with the trunk compartment.As shown in FIG. Some vehicles are equipped with a ventilation grill 3' on the rear edge of the trunk 2', and a ventilation system for discharging air from the vehicle interior through the trunk room R, as shown by the arrow in the figure.

[Problem that the invention seeks to solve]

The ventilation system having the above structure has a problem in that the ventilation efficiency is not good because the vehicle interior is ventilated through the trunk room R having a large capacity. In addition, in order to provide sufficient ventilation, it is necessary to make the grille 3' larger or to increase the gap l between the trunk lid 1 and the body panel B, but in the former case, the opening area of the trunk compartment becomes smaller. , and in the latter case, the appearance will be poor.

Therefore, in view of the above-mentioned problems, the present invention has been developed to provide a ventilation system that can secure a sufficient opening area of the trunk room, has a good appearance, and has extremely good ventilation efficiency in a vehicle that has a rear spoiler along the rear edge of the trunk lid. The purpose is to provide

[Means for solving problems]

In FIGS. 1 and 2, a reinforcement 2 is provided on the bottom surface of the trunk lid 1 in the front-rear direction (first
The reinforcement 2 forms a closed section with the lower surface of the trunk lid 1, with its front end (not shown) open and its rear end 21 closed. The open front end communicates with a ventilation hole formed in the partition wall between the passenger compartment and the trunk room.

On the other hand, the rear spoiler 3 provided along the rear edge of the trunk lid 1 has a ventilation opening 31 formed on its rear surface, and the ventilation opening 31 and the rear end 21 of the closed section
These are communicated through a through hole 11 formed in the trunk lid 1 and a passage 32 formed in the rear spoiler 3.

[action, effect]

Air in the vehicle interior flows through the reinforcement 2 and the passage 32, which have a closed cross section, and is exhausted from the ventilation port 31 (arrow in FIG. 1). Since the ventilation port 31 is directly communicated with the ventilation port of the vehicle interior by the reinforcement 2 without going through the large-capacity trunk room R, the above-mentioned exhaust gas is efficiently carried out.

Since the ventilation opening 31 is provided in the rear spoiler 3, even if the diameter of the ventilation opening 31 is increased, the opening area of the trunk room will not be restricted, and there is no need to increase the gap l between the trunk lid 1 and the body panel B. Looks good too.

〔Example〕

In FIG. 4, a rear spoiler 3 made of resin is provided along the rear edge of a trunk lid 1 of a vehicle, and ventilation holes 31 are formed on both sides of the rear surface of the spoiler 3. As shown in FIG. 3, the ventilation opening 31 communicates with a passage 32 formed in the rear spoiler 3 in the longitudinal direction, and the front end of the passage 32 is connected to the lower side edge of the trunk lid 1 through the through hole 11 of the trunk lid 1. It is communicated with a reinforcement 2 having a closed cross section, which will be described later, and which extends back and forth along the line.

In Fig. 2, the reinforcement 2 has a middle part bent downward in a convex shape and both sides joined to the lower surface of the trunk lid 1 to form a closed section, and the rear end 21 is closed (first figure).
The front end (not shown) of the reinforcement 2 is opened and communicated with a ventilation opening provided in a rear tray of the vehicle interior through a deformable connecting member such as a bellows. Note that a butterfly valve 4 for preventing flow from being sent midstream is provided in a passage 32 formed in the rear spoiler 3 (FIGS. 1 and 2).

In the ventilation system having the above structure, the air in the passenger compartment is supplied from the ventilation opening of the rear tray to the reinforcement 2 and the passage 3 communicating therewith, as shown by the arrow in FIG.
The air flows outward through the ventilation opening 31 by pushing open the butterfly valve 4 (dashed line in the figure). In particular, when the vehicle is running, negative pressure is generated on the rear surface of the rear spoiler 3, which promotes the outflow of the air. and,
In this case, the ventilation opening 31 directly communicates with the vehicle interior through the reinforcement 2 acting as a duct without passing through the large-capacity trunk room R on the way, so that the ventilation efficiency is extremely high.

By providing the ventilation opening 31 in the rear spoiler 3, even if it has a relatively large diameter, the problem of not being able to secure a sufficient opening area for the trunk room R as in the conventional device does not occur, and the gap size between the trunk lid 1 and the body panel B can be reduced. It doesn't need to be large, so it looks good.

Furthermore, the butterfly valve 4 provided in the passage 32 prevents backflow, preventing dust and the like from entering the passenger compartment.
