Abstract

<P>PROBLEM TO BE SOLVED: To provide a cowl louver for a vehicle, which generates only a little or no reaction force and can sufficiently absorb collision energy, when a load is applied to a hood panel or the like in a vehicle collision. <P>SOLUTION: A cowl louver 1 for the vehicle is provided with an opening part 5 in a cowl louver body 4 formed of polypropylene, and the opening part is sealed with a lid member 6, thereby preventing hot air and odor generated in an engine room from entering into a vehicle cabin via an air introducing port 4a. When the vehicle is collided, the collision energy is applied to a hood panel 2. When a lower part of a rear end of the hood panel 2 moves downward by being applied with a downward stress F, the lid member 6 is disengaged, and a part having the opening part 5 which is much less in strength is easily deformed and corrupted. Therefore, because only a little or no reaction force is generated, the collision energy can sufficiently be absorbed. Similarly, a downward stress F is applied to an upper protruding part of the cowl louver 1 for the vehicle when the vehicle is collided, the lid member 6 is disengaged, and the part having the opening part 5 is easily deformed and corrupted. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a vehicular cowl louver that is fitted to the lower end of a front window glass of a vehicle such as an automobile and extends to the rear side of the rear end of the hood panel, and in particular, the collision energy applied to the hood panel at the time of a vehicle collision. The present invention relates to a vehicle cowl louver that can be effectively absorbed.

  In a conventional automobile structure, a space is formed between the rear end of the hood panel that covers the engine room and the lower end portion of the front window glass, and this space is fitted to the lower end of the front window glass. The rear end of the hood panel is shielded by a resin cowl louver. As a result, hot air and odor in the engine room are prevented from entering the vehicle compartment via the air inlet provided in the cowl louver, and foreign matters such as dead leaves and snow accumulated in the space are entered in the engine room. Intrusion is prevented, and the situation where the engine room gets wet is also prevented.

  In this way, since the cowl louver is required to have a function of blocking both gas and solid, a certain degree of rigidity is required as a whole, and the tip part needs elasticity to be in close contact with the other party. An organic synthetic resin cowl louver has been used. However, if the cowl louver made of organic synthetic resin is too rigid, it will be difficult for the hood to move downward when a large downward load is applied to the hood during a vehicle collision, making it impossible to absorb the collision energy sufficiently. .

  Therefore, for the purpose of solving such a problem, Patent Document 1 discloses an invention of an automobile hood seal structure that shields a space between the rear end of the hood and the cowl top. In this automobile hood seal structure, a seal body is formed which has a rigidity capable of maintaining a shape from the rear end of the hood toward the space and has a positional relationship in which the tip does not interfere with the cowl top in the vertical direction. Either one of the front end of the main body or the cowl top is provided with an elastically deformable lip whose front end contacts the other side. Accordingly, when a downward load is applied to the hood at the time of a vehicle collision, the hood moves downward without generating a reaction force together with the seal body, and the collision energy can be sufficiently absorbed.

  Further, in the invention of the cowl top cover described in Patent Document 2, a vertical wall made of a soft member that alleviates the impact from the hood panel is integrally provided at the front end of the cowl louver main body made of a hard member. An extension portion extending from the main body side to the main body portion side is provided, and a reinforcing rib for connecting the main body side of the vertical wall to the extension portion or the main body side front end portion is provided. As a result, it is said that when the food panel receives an impact, the impact can be effectively mitigated while sufficiently ensuring the independence in normal times.

The rectangular lid member 16 is fitted so that the claw portions 16a and 16b of the lid member 16 are engaged with the opening 15 so as to maintain the sealing performance. As shown in FIG. 3A, a seal member 17 made of a rubber magnet as an elastic material is fixed to the front end upper portion of the vehicle cowl louver 11. The seal member 17 extends in a bar shape in the direction perpendicular to the paper surface of FIG. Further, the upper end of the round A cowl 8 is engaged with the engaging portion 14 c provided on the lower surface of the cowl louver main body 14.

  Here, the claw portions 16a and 16b of the lid member 16 constituting the vehicle cowl louver 11 according to the second embodiment will be described with reference to FIG. As shown in FIG. 4A, the claw portions 16a and 16b of the lid member 16 according to the second embodiment have cross-sectional shapes that are substantially symmetrical with each other, and are shown in FIG. 4C. As described above, the lid member 6 is provided at two locations, the upper and lower sides, over substantially the entire upper and lower ends.

  As shown in FIG. 4B, in the lid member 16A according to the modification of the second embodiment, the claw portion 16a at the upper end is the same as the lid member 16 according to the second embodiment, but the lower end The claw portion 16 c has a cross-sectional shape different from that of the claw portion 16 b at the lower end of the lid member 16. In addition to this, various modifications can be used for the cross-sectional shapes of the claw portions at the upper and lower ends of the lid member 16.

  Thus, by providing the claw portions 16a and 16b or the claw portions 16a and 16c on the lid members 16 and 16A, the claw portions 16a and 16b or the claw portions when the lid members 16 and 16A are fitted into the opening 15 16a and 16c engage with the opening 15, and the outer peripheral ends of the lid members 16 and 16A are brought into close contact with the outer peripheral edge of the opening 15 so that the sealing property can be obtained more reliably. In addition, it is possible to reliably prevent a situation in which the position of the lid members 16 and 16A is shifted due to vibration or impact during normal traveling or is removed from the opening 15 in an extreme case.

  Another difference of the vehicular cowl louver 11 according to the second embodiment from the first embodiment is that, as shown in FIG. 3A, a seal member 17 is provided at the upper front end of the vehicular cowl louver 11.
