Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front body structure of a vehicle, and more particularly to an air conditioning air introduction structure for a vehicle in which an engine room having a hood that can be opened and closed is provided in front of a driver's seat. .

[0002]

2. Description of the Related Art Generally, in an automobile in which an engine room having an openable / closable hood is provided in front of a driver's seat, engine cooling water is disclosed, for example, as disclosed in Japanese Utility Model Laid-Open No. 63-156818. A radiator for radiating heat and a radiator such as a condenser for restoring the vapor phase refrigerant in the air conditioner to a liquid phase are usually arranged at the front end in the engine room.

[0003]

Among vehicles in which an engine is arranged in front of a driver's seat, a vehicle generally called a recreational vehicle (RV) has a high vehicle height and a limited vehicle body. There is a demand to increase the volume of the passenger compartment and the luggage compartment by making the longitudinal dimension of the passenger compartment as long as possible within the entire length. In order to satisfy this requirement, it is necessary to cut down the size of the engine room in the front-rear direction, and by doing so, it is possible to shorten the front overhang, so not only the degree of freedom in body design is improved, The practical minimum turning radius (radius of the circular trajectory drawn by the outside of the tip of the bumper during full-lock turning) and the shortest distance in front of the vehicle (percurability) that can get out of parallel parking are also shortened, which has the advantage of improving the maneuverability of the vehicle. It is known to occur.

However, in a vehicle in which a radiator such as a radiator is arranged in front of the engine, there is a limit to the reduction of the dimension of the engine room in the front-rear direction, and an effective measure cannot be taken against the above demand. .

If the cowl box provided at the connecting portion between the rear end of the hood and the lower end of the windshield is omitted, the lower end position of the windshield can be moved forward, and that much of the vehicle compartment can be moved forward. Although the dimension in the front-rear direction can be lengthened and the degree of freedom in designing the instrument panel can be improved, in the conventional vehicle, an air conditioning air introduction duct for guiding the outside air to the air conditioner is opened in the cowl box. Therefore, when the cowl box is omitted, it is necessary to separately provide a duct for introducing air conditioning air.

In view of the above-mentioned circumstances, the present invention provides an air conditioning wind which can shorten the dimension of the engine room in the front-rear direction in a vehicle in which an engine room having an openable / closable hood above the engine is provided in front of the driver's seat. An object is to provide a front body structure of a vehicle having an introduction structure.

[0007]

In the front body structure of a vehicle according to the present invention, a radiator including a radiator of engine cooling water is provided inside the engine room in a space between the engine and the hood. In a mode, it is arranged above the engine, and in the space, an air-conditioning air introduction duct for guiding outside air to an air conditioner is arranged avoiding the radiator. is there.

According to a first aspect of the front body structure of a vehicle according to the present invention, a pair of left and right radiators are provided, and the pair of radiators are arranged on both sides of the air-conditioning air introduction duct in the center. It is characterized by being done.

A second aspect of the front body structure of a vehicle according to the present invention is characterized in that the air-conditioning air introducing duct is attached to the lower surface of the bonnet.

According to a third aspect of the front body structure of a vehicle according to the present invention, the duct for introducing the conditioned air is extended in the vehicle width direction above the suspension tower, and the tip of the duct for introducing the conditioned air is the engine. It is characterized in that it penetrates the side panel of the room and opens to the outside of the engine room.

[0011]

According to the present invention, a radiator such as a radiator of engine cooling water is arranged above the engine, and in the space between the engine and the bonnet,
The duct for introducing air conditioning that guides the outside air to the air conditioner is installed avoiding the radiator, and the cowl box is omitted, which reduces the dimension of the engine room in the front-rear direction. It becomes possible to lengthen the dimension in the direction. Moreover, since the front overhang can be shortened, not only the degree of freedom in designing the vehicle body is improved, but also the practical minimum turning radius is shortened, which improves the maneuverability of the vehicle.

In between, a reinforcing member 54 called a strut bar is bridged, and the rear portion of the superposed body of the radiator 22 and the condenser 24 is fixed on the reinforcing member 54. Further, the front portion of the superposed body is fixed to a frame member 34 called a shroud upper similar to the above-mentioned embodiment.

Further, in this embodiment, the fresh air duct 50 'whose base portion is fixedly connected to the side portion of the inside / outside air switching unit 38 includes the radiator 22 and the condenser 2.
One of the suspension towers 52
Is disposed above the vehicle to extend in the vehicle width direction, and the tip of the fresh air duct 50 'penetrates a side panel 56 called a wheel apron that forms a side wall of the engine room 10 from outside the engine room 10. It is configured to introduce fresh air.

As is apparent from the above description, the radiator 22 and the capacitor 24 are used in any of the embodiments.
Is disposed above the engine 16, and in the space between the engine 12 and the bonnet 20, an air conditioning air introduction duct 50 or 50 'for guiding the outside air to the air conditioner is provided in the radiator 2.
2 and the capacitor 24 are disposed to avoid the cowl box, the front-rear dimension of the engine room 10 is shortened, and the front-rear dimension of the vehicle compartment 8 can be lengthened accordingly. It will be possible. Moreover, since the front overhang can be shortened, the practical minimum turning radius is also shortened, and the maneuverability of the vehicle is improved.
