Problems solved by technology

Even if the pressing force acting on the supporting wall portion 85 from the upper road wall portion 81 is stopped, it is conceivably difficult to restore the original shape of the supporting wall portion 85
For this reason, such vehicle air intakes are also practically unusable after deformation

no. 1 approach

[0036] Such as Figures 1 to 3 As shown, the vehicle air intake according to this embodiment includes an upper wall portion 1 and a lower wall portion 4, the lower wall portion 4 is arranged opposite to the upper wall portion 1, and a required space is provided therebetween, and, The lower wall portion 4 and the upper wall portion 1 jointly form a laterally longer air intake opening 2 and an air intake channel 3 , and the air intake channel 3 supplies the engine side with external air sucked in from the air intake opening 2 . The opposite end portions of the upper channel wall portion 1 and the lower channel wall portion 4 are integrally joined together by fastening unshown bolts, thereby forming the air intake duct as a hollow body. It should be noted that the end portion of the air intake channel opposite to the air intake opening 2 is formed as an unshown connection opening, which can be connected with an unshown air filter.

[0037] When such a vehicle air intake is used,...

[0050] shown in Figure 4 In the present embodiment, the upper passage wall portion 1 has a pillar portion 5 and an engaging protrusion 14 as an engaging mechanism protruding outward from the outer peripheral surface of the distal end portion 5 a of the pillar portion 5 .

[0051] In addition, the lower road wall portion 4 as a fitting has a fixed passing portion 15, and is provided with a tubular buckle 17 fixed to the fixed passing portion 15. The tubular buckle 17 is formed by a rubber elastic material, and has a disengagement hole that constitutes a disengagement opening. Pass section 16. This tubular buckle 17 has an engagement recess 18 on its inner peripheral surface as a fitting engagement mechanism detachable from the engagement projection 14 .

[0052] In this vehicle air intake, the strut portion 5 is provided on the upper wall portion 1, and the tubular retaining ring 17 is fixed in the lower wall portion 4 as a fitting. When the part 14 and the engagement recess...

no. 3 approach

[0055] shown in Figure 5 In the present embodiment, the upper wall portion 1 has: a rod-shaped pillar portion 19 protruding toward the side of the lower wall portion 4 as a whole; 19 The outer peripheral surface of the distal end protrudes outward.

[0056] In addition, the lower channel wall portion 4 as a fitting part is integrally provided with an elastically deformable tubular portion 22 arranged at a position corresponding to the rod-shaped pillar portion 19 and has a detachment passage portion 21 constituting a detachment opening. The tubular portion 22 has an axially extending slit 22a so as to be able to withstand the enlargement in diameter by elastic deformation. This tubular portion 22 has a spherical engagement recessed portion 23 on its inner peripheral surface as a fitting engagement mechanism detachable from the spherical engagement protrusion 20 .

[0057] In this vehicle air intake, when the spherical engagement protrusion 20 provided on the distal end port...

Abstract

A grommet provided with an annular engaging groove serving as an engaging means is fixed to a distal end portion of a column portion. A mating engaging means, which has a through hole serving as an escape opening and is detachable with the annular engaging groove by an opening peripheral edge portion defining this through hole, is formed in a lower duct wall portion at a position corresponding to the column portion. If an external load of a predetermined value or more is applied to an upper duct wall portion, and a state of engagement between the annular engaging groove and the opening peripheral edge portion is thereby canceled, the column portion enters the through hole without being fractured or damaged, and the upper duct wall portion is deformed toward the lower duct wall portion side.

Description

[0001] This application is based on Japanese Patent Application No. 2005-089332, the contents of which are incorporated herein by reference. technical field [0002] The present invention relates to a vehicle air intake duct, and, more particularly, to a vehicle air intake duct having a strut portion which serves as a so-called rib and is provided to ensure resistance to intake negative pressure, etc. rigidity. Background technique [0003] The vehicle intake port is used to supply the external air taken in from the outside to the engine through the air filter, and improve the combustion efficiency of the engine, thereby increasing the output power of the engine. There are cases in which such a vehicle intake duct is installed in a gap between a hood (hood panel) at the front of the vehicle body and a radiator upper bracket to efficiently suck in outside air during running of the vehicle. [0004] In such a vehicle intake port, intake negative pressure (a phenomenon in whic...
