Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage structure of a door speaker mounting portion of an automobile, which prevents rainwater or the like flowing into the door panel of the automobile from flowing into the passenger compartment through a speaker mounting hole built in the door panel.

[0002]

2. Description of the Related Art As shown in FIGS. 8 and 9, a door panel 100 of an automobile has a mounting hole 102 formed in a door inner panel 101 which constitutes the door panel 100, and a speaker bracket 103 is inserted in the mounting hole 102. There is one in which the speaker 104 is attached. A door trim 105 is provided on the front surface of the door inner panel 101, and the speaker 10 is attached to the door trim 105.
4, the opening hole 106 is formed, and the speaker hole 107 is provided in the opening hole 106.

However, rainwater or the like flowing along the windshield 108 may flow into the door panel 100 from the belt line portion of the door panel 100, and may flow along the outer surface of the speaker bracket 103 into the vehicle compartment from the mounting hole 102. .

Therefore, as shown in FIG. 10, the waterproof 10 serving as a shield on the rear surface side of the speaker 104.
9 was provided to prevent water from entering.

[0005]

However, it is not sufficient to cover water with only the waterproof 109, and the gap of the waterproof 109 is not enough.
Alternatively, the water penetrates the wiring of the speaker 104 and water enters the vehicle interior. Moreover, since the waterproof 109 is provided at the rear of the speaker 104, the performance of the speaker 104 cannot be fully exhibited.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and provide a drainage structure for a door speaker mounting portion of an automobile capable of preventing rainwater or the like from flowing into the passenger compartment through the speaker mounting hole.

[0007]

In order to solve the above problems, the present invention provides a speaker in a speaker mounting hole formed in a door inner panel, and a door trim provided on the front surface of the door inner panel is provided with the above-mentioned speaker. In the drainage structure of the door speaker mounting portion of the automobile in which the opening is formed corresponding to the speaker and the speaker cover is arranged in the opening, a passage communicating with the inside of the door inner panel is provided under the speaker cover. Especially.

[0008]

[Operation] Most of the rainwater that has flowed into the door panel is discharged from the lower part of the door panel, and part of it flows into the inside of the door inner panel through the speaker mounting holes. The rainwater and the like collect in the lower part of the speaker cover and are discharged into the door panel through a passage communicating with the door inner panel.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIGS. 1 to 3, 1 is a vehicle body, 2 is a door panel provided on both side surfaces of the vehicle body, and 3 is a window glass provided on the door panel 2. The door panel 2 is composed of a door outer panel 4 and a door inner panel 5, and a door trim 6 is provided on the indoor side of the door inner panel 5.

A speaker mounting hole 7 is formed in the door inner panel 5, and a speaker 9 is provided in the speaker mounting hole 7 via a speaker bracket 8. An opening hole 10 is formed in the door trim 6 so as to face the speaker 9, and a speaker cover 11 is attached to the opening hole 10.

As shown in FIGS. 4 to 7, the speaker cover 11 has a passage 12 at the lower end which communicates with the inside of the door inner panel 5. This passage 1
As shown in FIG. 2, the reference numeral 2 penetrates a sealing cover 13 provided outside the door inner panel 5 and is introduced inside the door inner panel 5.

According to the above structure, among rainwater and the like flowing through the window glass 3 into the door panel 2, rainwater and the like flowing out to the outside of the door inner panel 5 through the speaker mounting hole 7 travels along the wall surface of the speaker bracket 8 and the door trim. Accumulate outside of 6. The rainwater or the like is discharged inside the door inner panel 5 through the passage 12 on the back side of the speaker cover 11.

According to the above embodiment, the speaker mounting hole 7
Speaker cover 1 for rainwater etc.
1 can be discharged to the inside of the door inner panel 5 through the passage 12 on the back side. Since the waterproof provided on the rear side of the speaker 9 can be eliminated, the performance of the speaker 9 can be improved and it is economical.

[0015]

As described above, the drainage structure of the door speaker mounting portion of the vehicle according to the present invention has the following effects. The speaker according to claim 1, wherein a speaker is arranged in a speaker mounting hole formed in the door inner panel, and an opening is formed in a door trim arranged in front of the door inner panel so as to correspond to the speaker. In the drainage structure of the door speaker mounting portion of the automobile where the speaker cover is arranged in, since the passage communicating with the inside of the door inner panel is provided in the lower portion of the speaker cover,
It is possible to prevent rainwater and the like from entering the passenger compartment through the speaker mounting hole.
