상기 어퍼 케이스(100)와 로어 케이스(200)는 대략의 원통 형상으로 형성되며, 볼트 등의 체결 부재를 통해 서로 결합된다.The upper case 100 and the lower case 200 are formed in a substantially cylindrical shape and are coupled to each other through fastening members such as bolts.
상기 어퍼 케이스(100)의 일 측부에는 차체에 고정을 위한 체결홀(150)이 형성된 플랜지부(140)가 형성되고, 다른 측부에는 전기적 신호의 전달 또는 전력의 전달을 위한 커넥터(130)가 형성된다.One side of the upper case 100 is formed with a flange portion 140 is formed with a fastening hole 150 for fixing to the vehicle body, the other side is formed with a connector 130 for the transmission of electrical signals or power transmission do.
상기 어퍼 케이스(100)의 내측에는 상기 진동판(400)의 타측의 안착을 유도하는 단차부(160)가 형성된다.A stepped portion 160 is formed inside the upper case 100 to induce mounting of the other side of the diaphragm 400.
상기 어퍼 케이스(100)의 상단면(110)은 소리의 전파를 위해 일정한 곡률의 상단면(110)을 갖도록 형성된다. 즉, 상기 상단면(110)은 하 방향으로 함입된 형태로 형성되고, 상기 상단면(110)의 중앙부에는 둠 형상의 돌출부가 형성된다. 상기 돌출부의 가장자리에는 진동판(400)으로부터 나는 소리를 어퍼 케이스(10)의 외부로 효과적으로 방출하기 위한 음방출 홀(120)이 형성된다.The top surface 110 of the upper case 100 is formed to have a top surface 110 of a predetermined curvature for the propagation of sound. That is, the upper end surface 110 is formed to be recessed in the downward direction, and the center portion of the upper end surface 110 is formed with a dome-shaped protrusion. A sound emission hole 120 is formed at the edge of the protrusion to effectively emit the sound from the diaphragm 400 to the outside of the upper case 10.
상기 압전판(300)은 피에조 소자로 이루어지며, 상기 인쇄회로기판(500)과 전기적으로 연결되어 상기 인쇄회로기판(500)으로부터 전기 신호를 인가받을 경우 진동한다.The piezoelectric plate 300 is formed of a piezoelectric element, and is electrically connected to the printed circuit board 500 to vibrate when an electric signal is applied from the printed circuit board 500.
상기 진동판(400)은 상기 압전판(300)에 일측이 지지되어 상기 압전판(300)이 진동할 경우 더불어 진동하여 소리를 발생시킨다.One side of the diaphragm 400 is supported by the piezoelectric plate 300 to vibrate when the piezoelectric plate 300 vibrates to generate sound.
상기 진동판(400)은 소리의 효과적인 발생을 위하여 도시된 것처럼, 나팔관 형상으로 형성되는 것이 바람직하다. 즉, 상기 압전판(300)에 지지되는 일측의 직경이 가장 작고, 상측으로 갈수록 그 직경이 점점 커지는 형상으로 이루어진다.The diaphragm 400 is preferably formed in the fallopian tube shape, as shown for effective generation of sound. That is, the diameter of one side that is supported by the piezoelectric plate 300 is the smallest, and the diameter is gradually increased toward the upper side.
상기 인쇄회로기판(500)은 상기 압전판(300)과 전기적으로 연결되어 상기 압전판(300)으로 전기 신호를 인가한다.The printed circuit board 500 is electrically connected to the piezoelectric plate 300 to apply an electrical signal to the piezoelectric plate 300.
상기 인쇄회로기판(500)은 상기 압전판(300)으로부터 일정 거리 이격된 위치에 배치되되, 상기 진동판(400) 및 상기 압전판(300)과 함께 일렬로 배치된다. 이와 같이 상기 인쇄회로기판(500)을 상기 진동판(400) 및 상기 압전판(300)과 함께 일렬로 배치할 경우 차량용 사이렌의 크기가 축소될 수 있게 된다.The printed circuit board 500 is disposed at a position spaced apart from the piezoelectric plate 300 by a predetermined distance, and is arranged in line with the vibration plate 400 and the piezoelectric plate 300. As such, when the printed circuit board 500 is arranged in a line with the diaphragm 400 and the piezoelectric plate 300, the size of the vehicle siren may be reduced.
상기 실링 및 탄성 유지 구조체(600)는 상기 진동판(400)과 상기 어퍼 케이스(100) 사이를 밀폐하면서 상기 진동판(400)이 상기 어퍼 케이스(100)에 탄성 지지되도록 하기 위한 구성이다. 따라서 상기 실링 및 탄성 유지 구조체(600)는 연질의 재질로 이루어지는 것이 바람직하다.The sealing and elastic retaining structure 600 is configured to allow the diaphragm 400 to be elastically supported by the upper case 100 while sealing the space between the diaphragm 400 and the upper case 100. Therefore, the sealing and elastic retaining structure 600 is preferably made of a soft material.
상기 실링 및 탄성 유지 구조체(600)는 상기 압전판(300)에 지지되지 않는 상기 진동판(400)의 타측과 상기 어퍼 케이스(100)에 동시에 접촉하도록 설치된다. 따라서 상기 진동판(400)과 상기 어퍼 케이스(100) 사이는 밀폐될 수 있게 되고, 이와 더불어 상기 진동판(400)의 탄성도 유지될 수 있게 된다.The sealing and elastic retaining structure 600 is installed to simultaneously contact the other side of the diaphragm 400 and the upper case 100 which are not supported by the piezoelectric plate 300. Therefore, the diaphragm 400 and the upper case 100 may be sealed, and the elasticity of the diaphragm 400 may also be maintained.
이하에서는 상기 실링 및 탄성 구조체(600)의 설치 구조에 대한 다양한 실시예를 살펴본다.Hereinafter, various embodiments of the installation structure of the sealing and elastic structure 600 will be described.
도 4는 본 발명의 실시예에 따른 차량용 사이렌에 적용된 실링 및 탄성 구조체의 설치 구조에 대한 제1 실시예를 나타낸 도면이다.Figure 4 is a view showing a first embodiment of the installation structure of the sealing and elastic structure applied to the vehicle siren according to an embodiment of the present invention.

It is installed to contact the inner surface 170 of the upper case 100 adjacent to the step portion 160 at the same time.
이와 같은 실링 및 탄성 구조체(600)의 설치 구조의 경우 상기 진동판(400)의 타측 상면을 상기 어퍼 케이스(100)의 단차부(160)에 접촉시킨 상태에서 실링 및 탄성 구조체(600)의 형성을 위한 몰딩액을 도포해 주면 되기 때문에 설치 구조가 단순하여 작업 시간이 적게 소요된다. 다만, 상기 실링 및 탄성 구조체(600)의 타측이 하 방향으로의 탄성만 유지되기에 도 6에 도시된 실시예와 같이 상 방향 및 하 방향으로의 탄성이 유지되도록 한 경우 비교하여 내구성 향상 효과가 떨어질 수는 있다.In the case of the installation structure of the sealing and elastic structure 600, the sealing and elastic structure 600 is formed in the state in which the other upper surface of the diaphragm 400 is in contact with the stepped portion 160 of the upper case 100. Since it is necessary to apply the molding liquid for it, the installation structure is simple and the work time is reduced. However, since the other side of the sealing and the elastic structure 600 is maintained only in the downward direction, as compared to the case where the elasticity in the up and down directions is maintained as shown in FIG. You can fall.
한편, 도 5는 본 발명의 실시예에 따른 차량용 사이렌에 적용된 실링 및 탄성 구조체의 설치 구조에 대한 제2 실시예를 나타낸 도면이다.On the other hand, Figure 5 is a view showing a second embodiment of the installation structure of the sealing and elastic structure applied to the vehicle siren according to an embodiment of the present invention.
도 5를 참조하면, 상기 실링 및 탄성 유지 구조체(600)는 상기 어퍼 케이스(100)의 단차부(160) 및 상기 단차부(160)와 인접한 어퍼 케이스(100)의 내측면(170)에 동시에 접촉하도록 설치되고, 상기 진동판(400)의 타측 상면은 상기 어퍼 케이스(100)의 단차부(160)로부터 이격된 위치에서 상기 실링 및 탄성 유지 구조체(600)와 접촉하도록 설치된다.Referring to FIG. 5, the sealing and elastic retaining structure 600 is simultaneously on the stepped portion 160 of the upper case 100 and the inner surface 170 of the upper case 100 adjacent to the stepped portion 160. The upper surface of the other side of the diaphragm 400 is installed to contact the sealing and elastic retaining structure 600 at a position spaced apart from the stepped portion 160 of the upper case 100.
이와 같은 실링 및 탄성 구조체(600)의 설치 구조의 경우 상기 실링 및 탄성 유지 구조체(600)를 상기 어퍼 케이스(100)의 단차부(160) 및 상기 단차부(160)와 인접한 어퍼 케이스(100)의 내측면(170)에 동시에 접촉하도록 설치하면서 상기 진동판(400)의 타측 상면을 상기 실링 및 탄성 구조체(600)에 접촉되도록 설치하는 것이기 때문에 상술한 제1 실시예와 같이 설치 구조가 단순하여 작업 시간이 적게 소요된다. 다만, 상기 실링 및 탄성 구조체(600)의 타측이 상 방향으로의 탄성만 유지되기에 도 6에 도시된 실시예와 같이 상 방향 및 하 방향으로의 탄성이 유지되도록 한 경우 비교하여 내구성 향상 효과가 떨어질 수는 있다.In the case of the installation structure of the sealing and elastic structure 600, the sealing and elastic retaining structure 600, the upper case 100 and the upper case 100 adjacent to the step portion 160 Since the upper surface of the diaphragm 400 is installed to be in contact with the seal and the elastic structure 600 while being installed to be in contact with the inner surface 170 at the same time, the installation structure is simple as in the first embodiment. It takes less time. However, since the other side of the sealing and the elastic structure 600 is maintained only in the elasticity in the upper direction, as compared with the case where the elasticity in the upper and lower directions is maintained as in the embodiment shown in FIG. You can fall.
한편, 도 6은 본 발명의 실시예에 따른 차량용 사이렌에 적용된 실링 및 탄성 구조체의 설치 구조에 대한 제3 실시예를 나타낸 도면이다.On the other hand, Figure 6 is a view showing a third embodiment of the installation structure of the sealing and elastic structure applied to the vehicle siren according to an embodiment of the present invention.
도 6을 참조하면, 상기 실링 및 탄성 유지 구조체(600)는 어퍼 케이스(100)의 단차부(160)와 이 단차부(160)와 인접한 어퍼 케이스(100)의 내측면(170)에 동시에 접촉하도록 설치되고, 상기 진동판(400)의 타측은 상기 어퍼 케이스(100)의 단차부(160)에 접촉되지 않는 상태로 상기 실링 및 탄성 유지 구조체(600)와 접촉하도록 설치된다.Referring to FIG. 6, the sealing and elastic retaining structure 600 simultaneously contacts the stepped portion 160 of the upper case 100 and the inner surface 170 of the upper case 100 adjacent to the stepped portion 160. The other side of the diaphragm 400 is installed to be in contact with the sealing and elastic retaining structure 600 without being in contact with the stepped portion 160 of the upper case 100.
이와 같은 실링 및 탄성 구조체(600)의 설치 구조의 경우 상기 상기 실링 및 탄성 유지 구조체(600)를 어퍼 케이스(100)의 단차부(160)와 이 단차부(160)와 인접한 어퍼 케이스(100)의 내측면(170)에 동시에 접촉하도록 설치하는 과정에서 상기 진동판(400)의 타측을 도포된 몰딩액 사이에 위치시키는 것이기에 설치 과정이 복잡하고 정확한 설치가 어려울 수 있으나, 상기 실링 및 탄성 구조체(600)의 타측에 대한 상 방향 및 하 방향으로의 탄성이 유지되기 때문에 내구성 향상 효과가 커질 수 있다.In the case of the installation structure of the sealing and elastic structure 600, the sealing and elastic retaining structure 600 is the step portion 160 of the upper case 100 and the upper case 100 adjacent to the step portion 160 In the process of installing so as to contact the inner surface 170 of the at the same time, the other side of the diaphragm 400 is located between the applied molding liquid, so the installation process may be complicated and accurate installation difficult, but the sealing and elastic structure 600 Since the elasticity in the up direction and the down direction with respect to the other side of) is maintained, the effect of improving durability can be increased.
한편, 도 7은 본 발명의 실시예에 따른 차량용 사이렌에 적용된 실링 및 탄성 구조체의 설치 구조에 대한 제4 실시예를 나타낸 도면이다.On the other hand, Figure 7 is a view showing a fourth embodiment of the installation structure of the sealing and elastic structure applied to the vehicle siren according to an embodiment of the present invention.
