Inner panel 11b
The air cleaner 1 disposed in the engine room is formed with a radiator grill 17 located at the front end of the vehicle body between the hood panel 11a and the hood panel 11a to form an air passage P reaching the inside of the engine room.
The connection opening portion 13a of No. 4 to the ventilation passage P side is located so as to be connected to the rear opening portion p2 of the ventilation passage P when the hood 11 is closed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an outside air introduction structure at a front portion of a vehicle body.

[0002]

[Prior art]

 As shown in FIGS. 3 and 4, in the conventional structure for introducing outside air in the front part of the vehicle body, as shown in FIGS. 3 and 4, a hood that covers the engine support formed above the radiator support 1 that separates the engine room from the outside. An air duct 3 is provided so as to pass under the inner panel 2a of the second inner panel 2a, a front opening 3a of the air duct 3 opens outside the engine room, and a rear opening thereof is arranged in the engine room. It is connected to the installed air cleaner 4. In such a structure, the outside air entering from the radiator grill 5 is introduced into the air cleaner 4 through the air duct 3.

Further, the outside air introducing structure shown in Japanese Utility Model Laid-Open No. 52-11024 has a special structure different from the above-mentioned structure. An air guide plate is fixed to the part, and an air passage is formed between the air guide plate and the hood panel. The baffle plate is located on the upper part of the radiator support, so that the ventilation passage is formed on the upper part of the radiator support. In such a ventilation passage, the front opening is open to the outside of the engine room, and the rear opening is connected to an air cleaner arranged in the engine room. In such a structure, the outside air entering from the radiator grill is introduced into the air cleaner through the ventilation passage.

[0004]

[Problems to be solved by the device]

 By the way, in the former outside air introduction structure among these outside air introduction structures, the position of the hood may be raised due to the air duct interposed above the radiator support, which may affect the limit of the downward visibility. In addition, since the front opening of the air duct is open toward the front, if water, snow, etc. are mixed in the outside air entering from the radiator grill, the air cleaner will be clogged due to these. May cause. Also in the latter outside air introduction structure, since the front opening of the ventilation passage is open toward the front, there is a risk of causing clogging of the air cleaner as described above. Since it is formed behind the inner panel, the hood itself becomes long. Therefore, the object of the present invention is to solve these problems.

[0005]

[Means for Solving the Problems]

 The outside air introduction structure of the vehicle body front portion according to the present invention is provided on the lower surface side of the inner panel forming the front portion of the hood that opens and closes the upper opening of the engine room formed at the front portion of the vehicle body, inside and outside the engine room, respectively. A pair of front and rear openings are provided to form an air passage to the inside of the engine room through a radiator grill located at the front end of the vehicle body between the inner panel and the hood panel of the hood. It is characterized in that the connecting opening portion of the provided air cleaner to the ventilation passage side is located so as to be connectable to the rear opening portion of the ventilation passage when the hood is closed.

[0006]

[Operation and effect of the device]

 In the outside air introduction structure having such a configuration, the ventilation passage communicates with the air cleaner by closing the hood, and the outside air can be introduced into the air cleaner. However, in the outside air introducing structure, since the air passage is formed between the inner panel and the hood panel that constitutes the hood located above the radiator support, the air duct of the former structure is not required. It can be omitted, and the height of the hood can be reduced, and the hood as in the conventional latter structure does not become long. Furthermore, in the outside air introduction structure, since the front and rear openings of the ventilation passage are both open downward, the outside air entering from the radiator grille has its flow direction reversed inside the ventilation passage, and It is not introduced straight into the air cleaner, and the occurrence of clogging due to the mixture of water and snow in the air cleaner is suppressed.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an outside air introducing structure according to the present invention, and FIG. 2 schematically shows a structure of a front part of a vehicle body. In the outside air introduction structure, the ventilation path P is formed between the hood panel 11a and the inner panel 11b that form the hood 11 that covers the upper opening of the engine room. The inner panel 11b is located above the radiator support 12 at the front end of the hood 11, and a pair of front and rear openings p1 and p2 are formed on the lower surface of the inner panel 11b in front of and behind the radiator support 12 respectively. . Of the openings p1 and p2, the front opening p1 is opened downward outside the engine room, and the rear opening p2 is opened downward inside the engine room.

In the air passage P, the rear opening p2 communicates with the air cleaner 14 via the first connecting pipe 13. The air cleaner 14 is disposed on one side of the radiator 15 at the rear portion of the radiator support 12 and is connected to the engine side via a second connecting pipe 16. The lower end of the first connecting pipe 13 is connected to the air cleaner 14, and the upper end of the first connecting pipe 13 is formed in a bellows-type pipe shape and opens upward. The opening 13a of the first connecting pipe 13 is located at a position facing the rear opening p2 when the hood 11 is closed, and is pressed against the inner panel 11b when the hood 11 is closed as shown in FIG. As a result, the first connecting pipe 13 is connected to the ventilation path P, and the air cleaner 14 communicates with the ventilation path P.

In the outside air introducing structure having such a structure, the communication between the air passage P and the air cleaner 14 is released when the hood 11 is opened, but the inner panel 11 b is closed at the upper end of the first connecting pipe 13 by closing the hood 11. The air passage P and the air cleaner 14 are in pressure contact with the opening 13a and communicate with each other via the first connecting pipe 13. As a result, the outside air that enters from the radiator grill 17 is introduced into the air passage P and is also introduced into the air cleaner 14 via the first connecting pipe 13.

In the outside air introducing structure, however, since the ventilation path P is formed between the hood panel 11a and the inner panel 11b that form the hood 11 positioned above the radiator support 12, the conventional outside air is not formed. The air duct used in the introduction structure can be omitted, the height of the hood can be reduced, and the hood 11 does not become long. Furthermore, in the outside air introducing structure, since the front and rear openings p1 and p2 of the ventilation passage P are both open downward, the outside air entering from the radiator grill 17 has a flowing direction in the ventilation passage P. Since the air cleaner 14 is not inverted and introduced straight into the air cleaner 14, the clogging caused by the mixture of water, snow, etc. in the air cleaner 14 is suppressed.
