TECHNICAL FIELD OF THE INVENTION
The present invention relates to a temporary installation structure of an air intake duct in a fender.
[0002]
[Prior art]
As shown in FIGS. 3 to 5, in an automobile 1, an air intake duct 4 that guides air to be taken into an engine (not shown) to an air cleaner 3 through an air intake pipe 2 has an intake air at an upper portion thereof. An intake resonator 5 for sound reduction is connected via a connecting pipe 6, and an air intake duct 4 to which the intake resonator 5 is connected at the top is a fender internal space defined by a fender panel 7 and an apron 8. 9 in some cases.
[0003]
When arranging the air intake duct 4 to which the intake resonator 5 is connected in the upper part in the fender internal space 9, as shown in FIG. 6, a sponge or urethane is formed so as to cover a required portion on the outer peripheral portion of the intake resonator 5. With the backlash preventing elastic member 10 such as rubber fixed, the intake resonator 5 and the air intake duct 4 are incorporated into the fender internal space 9, and the bracket 11 protruding from the apron 8 is attached to the air intake duct 4. The bolts 12 and the nuts 13 are tightened together with the protruding pieces 4a to fix the air intake duct 4, and the intake resonator 5 does not vibrate or hit the fender panel 7 or the apron 8 by the backlash preventing elastic member 10. It is like that.
[0004]
In the figure, 14 is a fender liner, 15 is an apron member, 16 is a hood panel, 17 is a hood inner panel, 18 is a weather strip, and 19 is a tire.
[0005]
[Problems to be solved by the invention]
However, the backlash preventing elastic member 10 is merely interposed between the intake resonator 5 and the fender panel 7 and the apron 8 to prevent the backlash of the intake resonator 5 and, as described above, the inside of the fender. The intake resonator 5 and the air intake duct 4 are assembled in the space 9, the projections 4 a of the air intake duct 4 are aligned with the brackets 11 projecting from the apron 8, and the bolts 12 and nuts 13 are tightened. There is no means for supporting the air intake duct 4 and the intake resonator 5 at the time of fixing, so that the workability is very poor.
[0006]
In view of such circumstances, the present invention can support the air intake duct by a backlash preventing elastic member for the intake resonator integrated with the air intake duct when assembling the air intake duct into the fender internal space. An object of the present invention is to provide a provisional structure of an air intake duct in a fender that can improve the performance.
[0007]
[Means for Solving the Problems]
The present invention is a temporary installation structure of an air intake duct in a fender for arranging an air intake duct to which an intake resonator is connected at an upper part in a fender internal space defined by a fender panel and an apron,
The capacity of the rattling preventing elastic member fixed so as to cover a required portion of the outer peripheral portion of the intake resonator is a capacity that is pushed into the fender internal space in a state where the rattling preventing elastic member is compressed, and the fender internal space has: the intake resonator integrated with an air intake duct, when pushed to the anti-rattle elastic member is compressed, the compressed rattle elastic member, the elastic force to be restored to its original shape A structure in which the air intake duct can be supported by engaging with a lightening hole as a hooking portion formed in a required portion of the apron corresponding to the rattling preventing elastic member in the fender internal space. The provisional structure of the air intake duct in the fender is described below .
[0008]
Thus, the air intake duct intake resonator is connected to the upper, in the state when disposed in the fender inner space, so as to cover the outer peripheral portion required portion of an intake resonator, which is fixed an elastic member for rattle, fender When the intake resonator is pushed into the internal space so that the rattling preventing elastic member is compressed, the rattling preventing elastic member is required to have an apron corresponding to the rattling preventing elastic member in the fender internal space due to its elastic force. In this state, the air intake duct is supported and held in a state in which it does not fall off even if the hand is released. The air intake duct can be fixed to the air intake duct.
[0009]
Also, the capacity of the rattling preventing elastic member is set to a capacity that is pushed into the fender internal space in a state where the rattling preventing elastic member is compressed , so that the intake resonator becomes more difficult to vibrate and noise is prevented. It is more effective from the aspect of.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0011]
FIGS. 1 and 2 show an example of an embodiment of the present invention. In the drawings, portions denoted by the same reference numerals as those in FIGS. This embodiment is the same as the conventional one shown in FIG. 6, but is characterized in that, as shown in FIGS. 1 and 2, the backlash is fixed so as to cover a required portion on the outer peripheral portion of the intake resonator 5. The capacity of the elastic member 10 is set to a capacity to be pushed into the fender internal space 9 in a state where the rattle preventing elastic member 10 is compressed, and the intake resonator 5 integrated with the air intake duct 4 is provided in the fender internal space 9. When the backlash preventing elastic member 10 is pushed in so as to be compressed, the backlash preventing elastic member 10 engages with a later-described hook formed in the fender internal space 9 by its elastic force, Air intake Lies in that adapted to support the transfected 4.
[0012]
In the case of the illustrated example, the engaging portion is provided with a lightening hole 20 at a required portion of the apron 8 corresponding to the rattling preventing elastic member 10 and narrows the apron 8 to the fender internal space 9 side. A configuration in which a protruding bead portion 21 for increasing the rigidity is formed, or the amount of constriction of the character line 7a of the fender panel 7 toward the fender internal space 9 is increased by the dimension A compared with the conventional example shown in FIG. Have.
[0013]
When the air intake duct 4 with the intake resonator 5 connected to the upper portion is disposed in the fender internal space 9 as described above, as shown in FIG. In this manner, with the rattling preventing elastic member 10 such as sponge or urethane rubber fixed, the intake resonator 5 is prevented from rattling in the fender internal space 9 above the character line 7a of the fender panel 7 or the bead portion 21 of the apron 8. When the elastic member 10 is pressed so as to be compressed, the elastic member 10 for preventing rattling is applied to the engaging portion formed in the fender internal space 9, namely, the lightening hole 20 of the apron 8 by its elastic force. At the same time, it is engaged with the bead portion 21 of the apron 8 or the inner side of the character line 7a of the fender panel 7, respectively. The air intake duct 4 is supported, and is held in a state where it does not fall off even if the user releases his / her hand. In this state, the projection 4a of the air intake duct 4 is aligned with the bracket 11 projecting from the apron 8. The air intake duct 4 can be fixed by tightening the bolt 12 and the nut 13.
[0014]
Further, by setting the capacity of the rattling preventing elastic member 10 to be a capacity that is pushed into the fender internal space in a state where the rattling preventing elastic member 10 is compressed , the intake resonator 5 becomes more difficult to vibrate, It is more effective in terms of noise prevention.
[0015]
Thus, when assembling the air intake duct 4 into the fender internal space 9, the air intake duct 4 can be supported by the backlash preventing elastic member 10 for the intake resonator 5 integrated with the air intake duct 4, and workability is improved. Improvement can be achieved.
[0016]
Incidentally, the temporary placement structure of the air intake duct in the fender of the present invention is not limited to the above-described illustrated example, and it goes without saying that various changes can be made without departing from the gist of the present invention.
