According to the door panel structure of the vehicle according to the present invention, the speaker mounting portion of the cover Since the inner steel plate and the guide are firmly fastened by extending the guide toward the inner steel plate, the bass of the speaker radiated to the rear of the speaker is tightly sealed, thereby reducing external leakage, and the speaker can produce tight bass. As the rigidity of the speaker is increased, vibration of the door panel due to the emission of the bass sound of the speaker is suppressed, thereby improving the output efficiency of the speaker.

Description

자동차의 도어판넬구조Door panel structure of automobile

본 고안은 자동차의 도어판넬측 스피커의 출력효율을 향상시키고, 특히 타이트한 중저음을 낼수 있도록 하는 자동차의 도어판넬구조에 관한 것이다.The present invention improves the output efficiency of the door panel side speaker of the vehicle, and more particularly relates to a door panel structure of the vehicle to make a tight bass.

종래의 자동차의 도어판넬구조는 도 1에 도시한 바와같이 차실외로 노출되는 외부철판(30)과, 상기 외부철판(30)의 일측면 단부와 결합되며, 후술되는 스피커(S)의 후면과 마주보는 부분에는 구멍(23)이 형성되어 있는 내부철판(20)과, 차실내로 노출되고, 스피커(S)가 장착될 수 있도록 공간이 형성되어 있으며, 상기 내부철판(20)의 일측면 단부에 끼워져 결합된 커버(10)로 이루어져 있다.The door panel structure of a conventional vehicle is coupled to the outer side plate 30 and the one side end of the outer side plate 30, which is exposed to the outside of the vehicle as shown in Figure 1, and the rear of the speaker (S) to be described later In the opposite part, the inner steel plate 20 having a hole 23 formed therein is exposed to the inside of the vehicle, and a space is formed so that the speaker S can be mounted, and one side end of the inner steel plate 20 is formed. Consists of a cover 10 coupled to the.

그런데, 상기와 같은 종래 자동차의 도어판넬구조는 커버가 내부철판 단부에 끼워져 결합하는 구조로 되어 있어 상기 커버와 상기 내부철판 사이에 틈새로 공기가 누설될 수 있다. 이로인해 스피커(S)가 중저음을 낼 때 스피커(S)후면을 통해 발산되는 중저음이 밀봉되지 않아 스피커(S)의 중저음을 재생하는데 문제점이 있다.However, the door panel structure of the conventional vehicle as described above has a structure in which the cover is fitted to the end of the inner steel plate to be coupled, so that air may leak into the gap between the cover and the inner steel plate. As a result, when the speaker S emits bass, the bass emitted through the rear surface of the speaker S is not sealed and there is a problem in reproducing the bass of the speaker S.

그리고, 또다른 문제점은 스피커(S)의 작동시 커버가 같이 떨게되어 소음발생의 원인이 되며, 스피커(S)의 효율을 저감시킨다는 것이다.In addition, another problem is that the cover is shaken together during operation of the speaker S, causing noise, and reducing the efficiency of the speaker S.

따라서, 본 고안은 상기와 같은 문제점을 해결하기 위해 이루어진 것으로서, 본 고안의 목적은 도어판넬측에 장착된 스피커에서 발생되는 중저음을 타이트하게 재생하고, 스피커의 출력효율을 향상시키기위한 자동차의 도어판넬구조를 제공하는데 있다.Therefore, the present invention has been made to solve the above problems, an object of the present invention is to reproduce the heavy bass generated from the speaker mounted on the door panel side tightly, the door panel of the car to improve the output efficiency of the speaker To provide structure.

상기의 목적을 달성하기 위해 본 고안의 일실시예에 의한 자동차의 도어판넬구조는 차실외로 노출되는 외부철판과, 상기 외부철판의 일측면 단부와 결합되며 일측에 구멍이 형성된 내부철판과, 상기 내부철판의 일측면 단부에 끼워져 결합되고, 스피커를 장착하도록 구성된 커버로 이루어진 자동차의 도어판넬구조에 있어서, 상기 커버는 스피커장착부위를 내부철판을 향해 가이드를 내어 상기 내부철판과 견고하게 체결하는 것을 특징으로 한다.In order to achieve the above object, the door panel structure of a vehicle according to an embodiment of the present invention is an external iron plate exposed to the outside of the vehicle, and an inner iron plate coupled to one side end of the outer iron plate and having a hole formed at one side thereof; In the door panel structure of the vehicle consisting of a cover fitted to one side end of the inner steel plate, and configured to mount the speaker, the cover is to fasten the speaker mounting portion toward the inner steel plate to securely fasten the inner steel plate It features.

이하, 본 고안의 일실시예에 의한 자동차의 도어판넬구조에 대하여 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, a door panel structure of a vehicle according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 고안의 일실시예에 의한 자동차의 도어판넬구조를 도시한 평단면도로서, 외부철판(30)과, 내부철판(20)과, 커버(15)로 구성되어 있다.FIG. 2 is a plan sectional view showing a door panel structure of a vehicle according to an embodiment of the present invention, and includes an outer steel plate 30, an inner steel plate 20, and a cover 15.

상기 외부철판(30)은 차실외로 노출되는 부위이고, 상기 내부철판(20)은 상기 외부철판(30)의 일측면 단부와 결합되며, 상기 커버(15)에 장착되는 스피커(S)의 후면과 마주보는 부분에는 일정크기의 구멍(23)이 형성되어 있고, 상기 커버(15)는 상기 내부철판(20)의 일측면 단부에 끼워져 결합되고, 스피커(S)를 장착할 수 있도록 구성되어 있다.The outer iron plate 30 is a portion exposed to the outside of the vehicle, the inner iron plate 20 is coupled to one side end of the outer iron plate 30, the rear of the speaker (S) mounted on the cover 15 A hole 23 having a predetermined size is formed in the portion facing the cover, and the cover 15 is fitted to one side end of the inner steel plate 20 to be coupled to the speaker S. .

그리고, 상기 커버(15)는 스피커(S)를 장착시키기위해 이 스피커(S)가 장착 되는 부위를 내부철판(20)을 향해 가이드(17)를 내어 상기 내부철판(20)과 견고하게 체결시킨다.In addition, the cover 15 securely fastens the guide 17 toward the inner steel plate 20 to mount the speaker S to mount the speaker S to the inner steel plate 20. .

상기와 같이 구성된 본 고안의 일실시예에 의한 자동차의 도어판넬구조에 대한 작용을 설명하기로 한다.The operation of the door panel structure of the vehicle according to the embodiment of the present invention configured as described above will be described.

먼저, 도어판넬측 스피커(S)가 작동되면, 음향이 차실내로 방사되는 동시에 상기 스피커(S)의 후면으로 일부의 음향이 방사되며, 특히 음향의 중저음이 상기 스피커(S)후면으로 방사될 때, 상기 중저음을 가이드(17)에 의해 견고하게 밀봉하여 내부철판(20)의 구멍(23)을 통해 상기 내부철판(20)과 외부철판(30)사이의 공간으로 방사되므로 상기 중저음의 외부누설이 감소되므로서, 스피커(S)가 타이트한 중저음을 낼 수 있다.First, when the door panel side speaker (S) is activated, the sound is radiated into the cabin and at the same time a part of the sound is emitted to the rear of the speaker (S), in particular the bass of the sound is radiated to the rear of the speaker (S) At this time, the heavy bass is tightly sealed by the guide 17 and is radiated into the space between the inner iron plate 20 and the outer iron plate 30 through the hole 23 of the inner iron plate 20, so that the external leakage of the bass sound is low. As this is reduced, the speaker S can produce tight bass.

또한, 상기 가이드(17)와 내부철판(20)이 견고하게 체결되어 스피커(S) 장착부위의 강성이 증대되므로 스피커(S)의 중저음으로 인한 도어판넬의 진동이 억제되어 스피커(S)의 출력효율이 향상된다.In addition, since the guide 17 and the inner steel plate 20 is firmly fastened to increase the rigidity of the mounting portion of the speaker S, vibration of the door panel due to the heavy bass of the speaker S is suppressed, thereby outputting the speaker S. The efficiency is improved.

상술한 바와 같이 본 고안에 의한 자동차의 도어판넬구조에 의하면, 커버의 스피커 장착부위를 내부철판을 향해 가이드를 내어 상기 내부철판과 가이드가 견고하게 체결되므로 스피커 후면으로 방사되는 스피커의 중저음이 견고하게 밀봉됨으로써 외부누설이 감소되어 스피커가 타이트한 중저음을 낼 수 있다는 효과가 있다.As described above, according to the door panel structure of the vehicle according to the present invention, the speaker mounting portion of the cover is guided toward the inner steel plate so that the inner steel plate and the guide are firmly fastened, so that the bass sound of the speaker radiated to the rear of the speaker is firmly By sealing, external leakage is reduced and the speaker can produce tight bass.

또 다른 효과는 스피커 장착부위의 강성이 증대되어 스피커의 중저음의 방사로 인한 도어판넬의 진동이 억제됨으로써 스피커의 출력효율이 향상된다는 뛰어난 효과가 있다.Another effect is that the rigidity of the speaker mounting portion is increased to suppress the vibration of the door panel caused by the emission of the bass sound of the speaker, thereby improving the output efficiency of the speaker.
