Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shock absorbing device for an air duct, which prevents a heat exchanger or the like connected to the air duct from being destroyed by a fug lamp or the like pressing a guide air duct when a vehicle collides.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 9, air is taken in from an air intake 21 at the lower part of a front bumper 20 of an automobile, and the heat exchanger 23 is cooled by air passing through a guide air duct 22.

[0003]

[Problems to be solved by the device]

 In the prior art, however, the fog lamp 24 incorporated in the bumper 20 has a problem in that when the vehicle collides, the guide air duct 22 is pushed in as shown in FIG. 9 and the main body of the heat exchanger 23 is destroyed. . This is because the guide air duct 22 is integrally made of resin as shown in FIGS. 10 and 11 and has a certain degree of hardness, so that the impact of a collision is transmitted to the guide air duct 22. The present invention aims to solve the above problems.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is a guide air duct that connects an air intake on the front of a vehicle to a heat exchanger, etc., and is a storage space where other automobile parts are installed on the side on the air intake side. It is characterized by having a space and forming a weak part on the wall surface facing the space and the heat exchanger.

[0005]

[Action]

 In the event of a car collision, even if a nearby part, such as a bumper as another automobile part built into the bumper, collides with the guide air duct, the weak part formed in the guide air duct is broken and Prevents destruction of parts connected to the guide air duct such as heat exchangers by entering the duct and absorbing impact.

[0006]

【Example】

 As shown in FIG. 1, an air intake 2 is formed in a bumper 1 at the front of an automobile, and a storage space 11 in which a fug lamp as another automobile component is installed is provided on the side of the air intake 2. Reference numeral 4 is a fender protector, and 5 is a heat exchanger, which connects the air intake 2 and the heat exchanger 5 with a guide air duct 6.

FIGS. 3 and 4 show a first embodiment of the present invention, in which a plurality of slits 7 are provided on a rear upper slope 6a as a wall surface facing the storage space 11 and the heat exchanger 5 of the guide air duct 6. The neck portion 7a is connected in a U-shape having an open upper portion. When the automobile collides and the hood 3 is pushed in as in 3 ', the portion 6a' surrounded by the slit 7 for breaking as a weak portion provided on the wall surface of the rear upper slope 6a is placed in the guide air duct as shown in FIG. It is deformed in one direction to absorb the shock and prevent the heat exchanger 5 from being broken.

FIG. 5 and FIG. 6 show a second embodiment of the present invention, in which a plurality of slits 8 are connected to the rear upper slope 6a of the guide air duct 6 and the parallel intermediate portions are vertically connected to each other by an H-shape. is doing. At the time of collision, as shown in FIG. 6, the portion surrounded by the slit for breaking is deformed inward of the guide air duct to absorb the impact.

7 and 8 show a third embodiment of the present invention, in which a plurality of slits 9 are connected to a rear upper slope 6a facing the heat exchanger of the guide air duct 6 and connected in a U-shape with an upper portion opened by 9a. Further, the bellows portion 10 is formed at the upper end of the slits 9 on both sides. At the time of collision, as shown in Fig. 8, the part surrounded by the slit for breaking is deformed inside the guide air duct to absorb the impact.

[0010]

Advantageous Effects of Invention According to the present invention, a guide air duct for connecting an air intake on the front of a vehicle and a heat exchanger, etc., in which other automobile parts are installed on the side of the air intake side Since there is a gap in the space and the wall surface facing the heat exchanger, adjacent parts such as a fog lamp break the guide air duct and absorb the impact at the time of a vehicle collision, resulting in high-value heat exchange. It is possible to prevent the destruction of the container or the radiator.
