하부캡(12)에는 홀더(21)가 접착제에 의하여 접착되고, 홀더(21)에는 렌즈(40)를 통과한 빛 중 가시광선만 통과시키는 필터(23)가 설치된다. 그리고, 홀더(21)에는 PCB(Printed Circuit Board)(31)가 조립되고, PCB(31)에는 센서(33)가 설치된다.The holder 21 is attached to the lower cap 12 by an adhesive, and the holder 21 is provided with a filter 23 for passing only visible light among the light passing through the lens 40. In addition, a printed circuit board (PCB) 31 is assembled to the holder 21, and a sensor 33 is installed on the PCB 31.

상기와 같은 종래의 카메라 모듈은 하부캡(12)과 홀더(21)가 접착제에 의하여 접착되므로, 결합력이 약하다. 이로인해, 낙하 충격 시험시 하부캡(12)으로부터 홀더(21)가 쉽게 분리되는 단점이 있다.In the conventional camera module as described above, since the lower cap 12 and the holder 21 are adhered by an adhesive, the bonding force is weak. Due to this, there is a disadvantage that the holder 21 is easily separated from the lower cap 12 during the drop impact test.

이하, 첨부한 도면을 참조하여 본 발명의 일 실시예에 따른 카메라 모듈 및 이에 사용된 모터를 상세히 설명한다.Hereinafter, a camera module and a motor used therein will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 일 실시예에 따른 카메라 모듈의 단면도이다.2 is a cross-sectional view of a camera module according to an embodiment of the present invention.

도시된 바와 같이, 본 실시예에 따른 카메라 모듈은 상호 결합되어 내부에 소정 공간을 형성하는 베이스(110)와 하우징(120)을 가진다. 즉, 베이스(110)는 하우징(120)의 저면 및 외면에 결합되어 하우징(120)을 지지한다.As shown, the camera module according to the present embodiment has a base 110 and a housing 120 are coupled to each other to form a predetermined space therein. That is, the base 110 is coupled to the bottom and the outer surface of the housing 120 to support the housing 120.

베이스(110)의 상면에는 하우징(120)에 결합되는 복수의 결합다리(111)가 형성되고, 중앙부에는 관통공(113)이 형성되며, 관통공(113)의 하부측 내주면에는 단면(段面)(115)이 형성된다. 그리고, 하우징(120)의 상면에는 후술할 렌즈(160)가 출입하는 출입공(123)이 형성되는데, 출입공(123)은 관통공(113)과 대향되게 형성된다.A plurality of coupling legs 111 coupled to the housing 120 are formed on an upper surface of the base 110, a through hole 113 is formed in a central portion thereof, and a cross section is formed on an inner circumferential surface of the lower side of the through hole 113. 115 is formed. In addition, an entrance hole 123 through which the lens 160 to be described later enters and exits is formed on an upper surface of the housing 120, and the entrance hole 123 is formed to face the through hole 113.

하우징(120)의 내부에는 링 형상의 요크(130)가 고정되고, 요크(130)의 내부에는 보빈(140)이 승강가능하게 설치된다. 그리고, 요크(130) 및 보빈(140)에는 상호 대향되게 마그네트(151) 및 코일(155)이 각각 고정된다. 그리하여, 코일(155)에 전류가 공급되면, 코일(155)에서 발생하는 전기장과 마그네트(151)에서 발생하는 자기장과의 작용에 의하여 코일(155)이 상승하고, 이로인해 보빈(140)이 상승한다. 그러면, 보빈(140)에 설치된 렌즈(160)도 상승하는 것이다.A ring-shaped yoke 130 is fixed to the inside of the housing 120, and a bobbin 140 is mounted to the inside of the yoke 130 to move up and down. In addition, the magnet 151 and the coil 155 are fixed to the yoke 130 and the bobbin 140 to face each other. Thus, when a current is supplied to the coil 155, the coil 155 is raised by the action of the electric field generated by the coil 155 and the magnetic field generated by the magnet 151, thereby raising the bobbin 140. do. Then, the lens 160 installed on the bobbin 140 also rises.

전자기력에 의하여 상승된 보빈(140)은 요크(130)의 상측 및 하측에 각각 설치된 스프링(171)에 의하여 하강되어 최초의 상태로 복귀된다. 요크(130)의 상면 및 하면에는 탄성을 가진 링 형상의 스페이서(Spacer)(175)가 각각 배치되는데, 스페이서(175)는 신축되면서 하우징(110)의 내부에 조립되는 부품들의 치수 공차 및 조립시 발생하는 조립 오차에 의한 공차를 보상해 준다.The bobbin 140 raised by the electromagnetic force is lowered by the springs 171 installed on the upper side and the lower side of the yoke 130 to return to the original state. Ring-shaped spacers 175 having elasticity are disposed on the upper and lower surfaces of the yoke 130, respectively. When the spacers 175 are stretched and dimensionally tolerated and assembled in the interior of the housing 110, Compensates for tolerances caused by assembly errors that occur.

베이스(110)의 관통공(113)측에는 필터(180)가 설치된다. 필터(180)는 관통공(113)의 내주면에 돌출 형성된 지지테(117)에 테두리부측이 지지 설치되며, 렌즈(160)를 통과한 빛을 필터링하여 가시광선만을 통과시킨다. 이때, 필터(180)는 관통공(113)의 상측 또는 하측에 설치될 수 있다. 지지테(117)의 상면에는 필터(180) 등과 같은 피지지체가 안정되게 지지될 수 있도록, 단면(段面)이 형성된다.The filter 180 is installed at the through hole 113 side of the base 110. The filter 180 supports the edge portion of the support frame 117 protruding from the inner circumferential surface of the through hole 113, and filters only the light passing through the lens 160 to pass only visible light. In this case, the filter 180 may be installed above or below the through hole 113. An upper surface of the support frame 117 is formed so that a supported body such as the filter 180 can be stably supported.

단면(115) 하측의 베이스(110) 저면에는 PCB(Printed Circuit Board)(190)가 조립되고, PCB(190)에는 필터링된 빛을 수신하여 광신호를 이미지신호로 변환 및 전달하는 센서(195)가 설치된다.A printed circuit board (PCB) 190 is assembled at the bottom of the base 110 under the cross section 115, and the sensor 190 converts and transmits an optical signal to an image signal by receiving filtered light. Is installed.

본 실시예에 따른 카메라 모듈은 필터(180)가 베이스(110)에 직접 설치되므로, 필터(180)를 수용하는 홀더가 필요 없다. 그러므로, 베이스(110)로부터 상기 홀더가 떨어질 우려가 없을 뿐만 아니라, 상기 홀더를 베이스(110)에 결합하는 공정도 필요 없다.
카메라 모듈의 구성 요소 중, 렌즈(160), 필터(180) 및 센서(195)를 제외한 구성 요소가 모터를 이루는 구성 요소이다.In the camera module according to the present embodiment, since the filter 180 is directly installed in the base 110, a holder for accommodating the filter 180 is not required. Therefore, there is no fear of the holder falling from the base 110, and there is no need for a process of coupling the holder to the base 110.
Among the components of the camera module, components except for the lens 160, the filter 180, and the sensor 195 constitute the motor.

Due to the coupling protrusion 217 and the coupling hole 290a, not only the PCB 290 can be firmly coupled to the base 210, but also the PCB 290 can be coupled to the correct position of the base 210. .

이상에서 설명한 바와 같이, 본 발명에 따른 카메라 모듈 및 이에 사용된 모터는 베이스의 저면에 빛을 필터링하는 필터가 직접 결합된다. 그러므로, 종래와 같이 필터가 설치된 홀더가 베이스로부터 분리될 우려가 없다.As described above, the camera module and the motor used therein according to the present invention is directly coupled to the filter for filtering light on the bottom of the base. Therefore, as in the prior art, there is no fear that the holder provided with the filter is separated from the base.

또한, 필터가 설치된 홀더를 베이스에 결합할 필요가 없으므로, 조립공정이 간편하다.In addition, there is no need to combine the holder with the filter to the base, the assembly process is easy.

또한, 베이스 및 PCB에 각각 형성되어 상호 삽입 결합되는 결합돌기 및 결합공으로 인하여, PCB가 베이스에 견고함과 동시에 정확한 위치에 결합된다.In addition, due to coupling protrusions and coupling holes formed on the base and the PCB, respectively, inserted and coupled to each other, the PCB is firmly coupled to the base and simultaneously coupled to the correct position.
