[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a traveling wind introduction structure in which, for example, in a one-box type or a cab-over type vehicle, traveling wind is introduced from an opening of a front bumper and is sent to a radiator, an air conditioner, an engine moor, etc. Particularly, it relates to a structure capable of improving ventilation efficiency without increasing the number of parts.

[0002]

[Prior Art]

 For example, in a one-box type automobile, an engine is mounted near the lower part of the driver's seat, and an intake device for introducing outside air into the engine is provided. As shown in FIGS. 5 and 6, this intake device generally has an air intake chamber 21 disposed between a front cross member 26 and a front bumper 22, and a duct inlet 21a of the air intake chamber 21 located above the front bumper 22. It is located near the rear of the front grill 23 to prevent rainwater from entering, and has a structure in which an extended end of the duct outlet 21b of the chamber 21 is connected to an air cleaner 24 arranged near the engine 25. . Further, in the above-mentioned automobile, in order to blow the traveling air to the radiator 27, the engine room, the air conditioner, etc., an opening 22a is conventionally formed in the central portion in the width direction of the front bumper 22, and the traveling from the opening 22a. I try to introduce the wind.

[0003]

[Problems to be solved by the device]

 However, in the above-described conventional traveling air introduction structure, since the intake chamber 21 is disposed at a position that traverses the opening 22a of the front bumper 22, the intake chamber 21 is driven by the traveling air (see → mark in FIG. 6). ) Is prevented when it is introduced into the radiator 27 and the like, and moreover, it is easy to get caught in the lower portion of the cross member 26 from the opening 22a. Therefore, there is a problem that ventilation efficiency is poor. Here, for example, Japanese Utility Model Laid-Open No. 55-25503 proposes that a wind guide plate is attached to the lower edge of the radiator and the traveling wind is introduced by the wind guide plate. However, in this case, there is a problem that the cost increases as much as another component is attached.

The present invention has been made in view of the above conventional circumstances, and an object of the present invention is to provide a traveling wind introduction structure for a vehicle that can improve ventilation efficiency without increasing cost.

[0005]

[Means for Solving the Problems]

 In view of this, the present invention is directed to a traveling wind introduction structure for an automobile, in which an intake chamber is provided between a front bumper and a front cross member, and an opening for introducing a traveling wind is formed in the front bumper. Is disposed in a space between the front cross member and a portion below the opening of the front bumper, and the upper surface of the intake chamber is formed to be substantially continuous with the lower edge of the opening. Is characterized by.

[0006]

[Action]

 Since the intake chamber is arranged in the space below the opening of the front bumper and the front cross member, the intake chamber is hidden under the front bumper. Therefore, it does not hinder the introduction of running wind. Further, since the upper surface of the intake chamber is formed so as to be substantially continuous with the opening, the upper surface of the intake chamber functions as a baffle plate, so that the introduced running wind is circulated below the cross member. It can be supplied to radiators without any problem, and ventilation efficiency can be improved accordingly. Further, in the present invention, since the structure is such that only the arrangement position and shape of the intake chamber are changed, there is no need for a separate part as in the above publication, and the cost is hardly increased.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 to 3 are views for explaining a traveling wind introduction structure of an automobile according to an embodiment of the present invention. In the figure, reference numeral 1 denotes a one-box type vehicle to which the structure of this embodiment is applied. An engine 2 is mounted near a lower portion of a driver's seat 1a of the vehicle 1, and a radiator 3 is provided in front of the engine 2. It is arranged. Further, a front cross member 4 having a generally U-shaped cross section extending in the vehicle width direction is arranged at the lower front end of the automobile 1, and both ends of the cross member 4 are provided on left and right sides of a vehicle body (not shown). It is joined to the front end of the side member.

Further, a resin front bumper 6 extending in the vehicle width direction is disposed below the front panel 5 of the automobile 1, and the front bumper 6 is supported by the cross member 4. Openings 6a are formed in a grid pattern at the center of the front bumper 6, and the radiator 3 is located behind the openings 6a. Reference numeral 7 denotes a license plate attached to the lower center of the opening 6a.

An air intake chamber 8 of an intake device for supplying air to the engine 2 is arranged in a space A formed between the cross member 4 and a portion 6 b of the front bumper 6 below the opening 6 a. The chamber 8 is supported by the cross member 4 via a bracket (not shown). The intake chamber 8 is formed in a size and shape that substantially fills the space A, and its dimension in the vehicle width direction is set to be substantially the same as the width dimension of the radiator 3. Further, the chamber 8 has a capacity of, for example, about 3 liters. An outside air inlet duct 9a is connected to the intake chamber 8, and the duct 9a is located behind the license plate 7 and extends upward. Further, one end of a connecting duct 9b is connected to the left end portion of the intake chamber 8, and an extended end of the duct 9b is connected to an air cleaner of the intake device.

The upper surface 8a of the intake chamber 8 is formed in an inclined shape so as to be located on a line connecting the lower edge of the opening 6a at the lowermost end of the front bumper 6 and the upper edge 4a of the cross member 4. ing. As a result, a substantially continuous surface is formed from the lower edge of the opening 6a to the upper edge 4a of the cross member 4.

Next, the function and effect of this embodiment will be described. According to the traveling wind introduction structure of the present embodiment, the intake chamber 8 is arranged in the space A between the lower portion 6b of the front bumper 6 and the front cross member 4, so that the intake chamber 8 is the same as the front bumper 6 described above. Because it is hidden, it does not hinder ventilation when introducing running wind. Further, since the intake chamber 8 cannot be seen from the outside, it is possible to avoid deterioration of the appearance.

Further, in the present embodiment, the upper surface 8a of the intake chamber 8 is formed in an inclined shape so as to form a substantially continuous surface from the lower edge of the opening 6a to the upper edge 4a of the cross member 4. Therefore, the upper surface 8a of the intake chamber 8 serves as a baffle plate, and the traveling wind can be efficiently blown to the radiator 3, the air conditioner and the like. Further, since this efficiency improvement is realized only by changing the arrangement position and shape of the intake chamber 8, it is possible to suppress an increase in cost without requiring a separate component.

Furthermore, in the present embodiment, the intake chamber 8 is formed to have a size that maximally fills the space A, so that the capacity thereof can be increased and the intake noise to the air cleaner can be reduced accordingly.

In the above embodiment, the case where the upper surface 8a of the intake chamber 8 is formed in a slanted shape so as to form a continuous surface from the opening 6a to the upper edge 4a of the cross member 4 will be described as an example. However, the present invention is not limited to this, and for example, as shown in FIG. 4, the upper surface 8a of the intake chamber 8 may be formed so as to be substantially horizontal and may be substantially flush with the opening 6a. . Also in this case, the upper surface 8a of the intake chamber 8 functions as a baffle plate, and the effect of improving ventilation is obtained.

Further, although the one-box type automobile is shown as an example in the above embodiment, the present invention can be applied to other types of automobiles.
