Description

  The present invention relates to a front structure of an automobile.

A grill is set at the front of the automobile, and electronic components such as a millimeter wave radar and a camera that need to be installed at the front of the vehicle body are supported on the grill (for example, Patent Document 1).
JP 2003-4448 A

  However, in such a conventional technique, the grille supporting the electronic component has a structure having a large number of openings for ensuring air permeability, so that its own rigidity is low. Therefore, the support rigidity of the electronic component supported by such a grille is also low, and a large electronic component or a large number of electronic components cannot be supported.

  In addition, since the grill is exposed to the outside and no special measures against water and dust are taken, electronic components having a structure that is sensitive to water and dust cannot be supported on the grill.

  The present invention has been made by paying attention to such a conventional technique, and provides a front structure of an automobile that has high support rigidity of electronic parts and can improve waterproofness and dustproofness for electronic parts. To do.

  The invention according to claim 1 is a front structure of an automobile comprising at least a duct fixed to a vehicle body and a grill supported by the duct, wherein the electronic component is disposed at least in the duct. Or it supported in the state attached to either the vehicle body, It is characterized by the above-mentioned.

  The invention according to claim 2 is characterized in that the duct has a structure having at least an upper wall portion and a lower wall portion, and an electronic component is supported between the upper wall portion and the lower wall portion.

  The invention according to claim 3 is characterized in that the front of the duct is covered with a grill cover.

  According to a fourth aspect of the present invention, a plurality of electronic components are supported in a duct in a state where they are accommodated in one case, and a harness of each electronic component in the case is assembled into one connector provided in the case. It is characterized by being.

  According to the first aspect of the present invention, the duct for supporting the grill is fixed to the vehicle body, and the electronic component is supported in at least either the duct or the vehicle body in the duct, so that the support rigidity of the electronic component is increased. . In addition, the electronic component is protected by the duct, and the waterproofness and dustproofness of the electronic component are improved.

  According to the second aspect of the present invention, the duct has a structure having at least an upper wall portion and a lower wall portion, so that the waterproof property against rainwater from above and rebound water from below is improved.

  According to the invention described in claim 3, since the front of the duct is covered with the grill cover, the waterproofness and dustproofness against water from the front are further improved.

  According to the invention described in claim 4, since the plurality of electronic components are housed in one case and the harness of each electronic component is assembled in one connector, the duct for supporting the plurality of electronic components is provided. Is easy to assemble. Moreover, since it is accommodated in the case, waterproofness and dustproofness are further improved.

  A duct fixed to a vehicle body and supported by the duct for the purpose of providing a front structure of an automobile in which the electronic component has a high support rigidity and can improve waterproofness and dustproofness against the electronic component. This is a front structure of an automobile that is configured at least by a grill, and is realized by supporting an electronic component in the duct while being attached to at least either the duct or the vehicle body.

  A first embodiment will be described with reference to FIGS. FIG. 1 is a perspective view showing only the grill portion. FIG. 2 is a simplified cross-sectional view of the grille including the vehicle body portion. In FIG. 2, the grill is shown in a simplified plate shape.

  A radio core support 1 as a “vehicle body” is disposed at the front of the automobile, and a radiator 2 is supported behind the radio core support 1 (right side in FIG. 2; the same applies hereinafter). The left and right central portions of the radio core support 1 are continuous in the vertical direction, but ventilation openings (not shown) are formed on both the left and right sides.

  A resin duct 3 is fixed in front of the radio core support 1 (left side in FIG. 2; the same applies hereinafter). The duct 3 includes a rear wall portion 3a fixed along the radio core support 1, an upper wall portion 3b extending obliquely forward from an upper end portion of the rear wall portion 3a, and a lower portion positioned below the upper wall portion 3b. It is formed from the wall part 3c. A ventilation opening 4 is formed below the rear wall 3a. Accordingly, in the duct 3, a space S having an opening at the front is formed by the upper portion of the rear wall portion 3a, the upper wall portion 3b, and the lower wall portion 3c.

  A bumper reinforcement 5 is disposed below the space S of the duct 3, and a bumper fascia 6 is disposed in front thereof. A vent opening 7 is formed in the bumper fascia 6.

  The grill 8 is integrally assembled in front of the space S in the duct 3. Since the grill 8 is assembled to the duct 3 in advance, the mounting of the grill 8 is completed at the same time by fixing the duct 3 to the radio core support 1.

  An opening 9 is formed at the center of the grill 8, and a grill cover 10 is provided there. The grill cover 10 is formed of an AES resin having weather resistance. In the space S of the duct 3 located behind the grill cover 10, a millimeter wave radar 11 as an electronic component, a stereo camera (CCD) 12, and a case 14 containing a substrate 13 are installed. The millimeter wave radar 11 is for detecting an obstacle or the like in front of the vehicle, and the stereo camera 12 is also for monitoring the situation in front of the vehicle with an image.

  The case 14 is supported by the attachment 15 on the upper wall portion 3b and the rear wall portion 3a, and the rear portion is supported by the upper and lower two stays 16 on the rear wall portion 3a. The front end portion of the stay 16 passes through the case 14 and directly supports the millimeter wave radar 11. A connector 18 in which the millimeter wave radar 11, the stereo camera 12, and the harnesses 17 of the substrate 13 are gathered is provided above the rear portion of the case 14. The connector 18 is connected to another connector (not shown) extending from the vehicle body side.

  As described above, according to this embodiment, the duct 3 integrally assembled with the grill 8 is fixed to the radio core support 1 that is the vehicle body, and the millimeter that is the electronic component is placed in the space S of the duct 3. Since the wave radar 11, the stereo camera 12, and the substrate 13 are supported, the waterproofness and dustproofness of these electronic components are improved. That is, since the duct 3 has a structure having the upper wall portion 3b and the lower wall portion 3c, the waterproof property against rainwater from above and rebound water from below is improved. Furthermore, since the front of the space S of the duct 3 is covered with the grill cover 10 and each electronic component is stored in the case 14, the waterproofness and dustproofness of these electronic components are further improved.

  In addition, since the case 14 containing such electronic components is attached to the duct 3, the support rigidity of each electronic component is improved, and a large electronic component such as the millimeter wave radar 11 can be supported. It becomes possible to support.

  Further, since a plurality of electronic components are housed in one case 14 and the harness 17 of each electronic component is gathered in one connector 18, assembly to the duct 3 when supporting a plurality of electronic components is performed. Also gets better.

  In the above embodiment, the millimeter wave radar 11, the stereo camera 12, and the substrate 13 are exemplified as the electronic components, but the present invention is not limited to these. Moreover, although the example which connects the rear-end part of the stay 16 which supports the case 14 to the rear wall part 3a of the duct 3 was shown, in order to raise support rigidity further, this rear-end part of the stay 16 of the duct 3 was shown. You may make it penetrate the rear wall part 3a and connect with the radio core support 1 directly.
