Description

렌즈 구동용 모터 {MOTOR FOR DRIVING LENS}Lens Driving Motor {MOTOR FOR DRIVING LENS}

본 발명은 렌즈 구동용 모터에 관한 것이다.The present invention relates to a motor for driving a lens.

디지털기기의 다기능화 추세에 따라 카메라 및 MP3 플레이어 등이 내장된 디지털기기가 개발되어 사용되고 있다. 더욱이 디지털기기에 내장된 카메라의 렌즈를 자동으로 작동시키기 위한 렌즈 구동용 모터가 디지털기기에 설치되어 사용되고 있다.As digital devices become more versatile, digital devices with built-in cameras and MP3 players have been developed and used. Moreover, a lens driving motor for automatically operating a lens of a camera embedded in a digital device is installed and used in the digital device.

일반적으로, 렌즈 구동용 모터는 케이스의 내부에 승강가능하게 설치되어 렌즈를 승강시키는 캐리어(Carrier)를 가진다. 상기 캐리어는 전자기력에 의하여 상승하고, 상승된 상기 캐리어는 스프링력에 의하여 하강되어 최초의 상태로 복귀된다.In general, the lens driving motor has a carrier which is installed to be liftable inside the case and lifts the lens. The carrier is raised by the electromagnetic force, and the raised carrier is lowered by the spring force and returned to the original state.

상기 스프링은 직경이 다른 복수개의 링이 상호 연결되어 동심을 이루면서 배치된 형태로 형성되는데, 외주면측은 상기 케이스측에 지지되고 내주면측은 상기 캐리어의 외주면에 파묻혀 일체로 형성된다.The spring is formed in a shape in which a plurality of rings of different diameters are connected to each other concentrically, and the outer circumferential surface side is supported by the case side, and the inner circumferential surface side is integrally formed by being embedded in the outer circumferential surface of the carrier.

디지털기기의 박형화 및 슬림화에 따라 렌즈 구동용 모터도 박형화 및 슬림화된다.As the digital devices become thinner and thinner, the lens driving motors become thinner and thinner.

이로인해, 상기 캐리어의 외주면에 파묻히는 상기 스프링의 내주면측 부위의 면적이 작아 상기 스프링의 내주면측 일부 또는 전부가 상기 캐리어로부터 이탈하는 경우가 발생한다. 그러면, 상기 캐리어가 정확하게 동작하지 못하므로, 제품의 신뢰성이 저하되는 단점이 있다.As a result, the area of the inner circumferential surface side portion of the spring buried in the outer circumferential surface of the carrier is small, so that a part or all of the inner circumferential surface side of the spring is separated from the carrier. Then, since the carrier does not operate correctly, there is a disadvantage that the reliability of the product is lowered.

본 발명은 상기와 같은 종래 기술의 문제점을 해소하기 위하여 안출된 것으로, 본 발명의 목적은 신뢰성을 향상시킬 수 있는 렌즈 구동용 모터를 제공함에 있다.The present invention has been made to solve the above problems of the prior art, an object of the present invention to provide a lens driving motor that can improve the reliability.

상기 목적을 달성하기 위한 본 발명에 따른 렌즈 구동용 모터는, 베이스; 상기 베이스에 결합된 하우징; 상기 하우징의 내부에 승강가능하게 설치되며 렌즈가 설치된 캐리어(Carrier); 외주면측은 상기 하우징측에 지지 고정되고 내주면측은 상기 캐리어의 외주면에 결합되어 상기 캐리어를 탄성 지지하는 스프링을 포함하고,Lens driving motor according to the present invention for achieving the above object, the base; A housing coupled to the base; A carrier mounted on the inside of the housing to be movable up and down and having a lens installed therein; An outer circumferential surface side is supported and fixed to the housing side and an inner circumferential surface side is coupled to an outer circumferential surface of the carrier and includes a spring for elastically supporting the carrier,

상기 스프링의 내주면측에는 상기 캐리어가 통과하는 복수의 관통공이 형성된다.A plurality of through holes through which the carrier passes is formed on the inner circumferential surface side of the spring.

본 발명에 따른 렌즈 구동용 모터는 캐리어의 외주면측에 파묻히는 스프링의 내주면측 부위에 캐리어가 통과하는 관통공이 형성된다. 이로인해, 스프링이 캐리 어로부터 이탈하지 않으므로, 제품의 신뢰성이 향상된다.In the lens driving motor according to the present invention, a through hole through which a carrier passes is formed in a portion of an inner circumferential surface side of a spring buried in the outer circumferential surface side of the carrier. This improves the reliability of the product since the spring does not escape from the carrier.

이하, 첨부한 도면을 참조하여 본 발명의 실시예들에 따른 렌즈 구동용 모터를 상세히 설명한다.Hereinafter, a lens driving motor according to embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 일 실시예에 따른 렌즈 구동용 모터의 단면도이고, 도 2는 도 1에 도시된 스프링의 평면도이다.1 is a cross-sectional view of a lens driving motor according to an embodiment of the present invention, Figure 2 is a plan view of the spring shown in FIG.

도시된 바와 같이, 상호 결합되어 내부에 소정 공간을 형성하는 베이스(110)와 하우징(120)이 마련된다.As shown, the base 110 and the housing 120 are coupled to each other to form a predetermined space therein.

이하, 베이스(110)를 포함한 다른 구성 요소들의 면 및 방향을 지칭함에 있어서, 베이스(110)의 수직방향 상측을 향하는 면 및 방향을 "상면 및 상측", 수직방향 하측을 향하는 면 및 방향을 "하면 및 하측"이라 한다.Hereinafter, in referring to the plane and the direction of other components including the base 110, the plane and the direction toward the vertical direction upward of the base 110 "top and top", the plane and the direction toward the vertical bottom " Lower surface and lower side ".

하우징(120)은 하면이 개방되어 베이스(110)에 결합되고, 베이스(110) 및 하우징(120)의 상면에는 관통공(111) 및 출입공(121)이 상호 대응되게 형성된다.The lower surface of the housing 120 is coupled to the base 110, and the through hole 111 and the access hole 121 are formed to correspond to each other on the upper surface of the base 110 and the housing 120.

하우징(120)의 내부에는 링형상의 요크(130)가 고정되고, 요크(130)에는 링형상의 마그네트(140)가 고정된다. 그리고, 요크(130)의 내부에는 렌즈가 설치된 캐리어(Carrier)(150)가 승강가능하게 설치되고, 캐리어(150)의 외주면에는 코일(160)이 고정되어 마그네트(140)와 대향한다.A ring-shaped yoke 130 is fixed to the inside of the housing 120, and a ring-shaped magnet 140 is fixed to the yoke 130. In addition, a carrier 150 provided with a lens is provided inside the yoke 130 so as to be liftable, and a coil 160 is fixed to an outer circumferential surface of the carrier 150 to face the magnet 140.

그리하여, 코일(160)에 전류가 공급되면, 코일(160)과 마그네트(140)의 작용에 의하여 코일(160)이 상승하고, 이로인해 캐리어(150)가 상승하면서 상기 렌즈를 상승시킨다. 캐리어(150)는 출입공(121)을 출입한다.Thus, when a current is supplied to the coil 160, the coil 160 is raised by the action of the coil 160 and the magnet 140, thereby raising the lens while the carrier 150 is raised. The carrier 150 enters and exits the access hole 121.

하우징(120)의 상면과 요크(130)의 상면 사이 및 베이스(110)와 요크(130)의 하면 사이에는 탄성을 가진 제 1 및 제 2 스페이서(Spacer)(171,175)가 각각 설치된다. 제 1 및 제 2 스페이서(171,175)는 신축되면서 베이스(110)와 하우징(120)의 내부에 조립되는 부품들의 치수 공차 및 조립시 발생하는 조립 오차에 의한 공차를 보상해 준다.First and second spacers 171 and 175 having elasticity are respectively installed between the upper surface of the housing 120 and the upper surface of the yoke 130 and between the base 110 and the lower surface of the yoke 130. The first and second spacers 171 and 175 are stretched and compensate for the tolerance due to the dimensional tolerances of the components assembled in the base 110 and the housing 120 and the assembly errors generated during assembly.

요크(130)의 상하측에는 링형상의 스프링(180)이 설치된다. 코일(160)과 마그네트(140)의 작용에 의하여 상승된 캐리어(150)는, 코일(160)에 공급되는 전류가 차단되면, 스프링(180)에 의하여 최초의 상태로 복귀된다.Ring-shaped springs 180 are installed on the upper and lower sides of the yoke 130. The carrier 150 lifted by the action of the coil 160 and the magnet 140 is returned to the original state by the spring 180 when the current supplied to the coil 160 is cut off.

스프링(180)은 상이한 직경을 가지는 복수개의 링이 동심을 이루면서 배치된 형태를 이룬다. 스프링(180)은 제 1 스페이서(171)의 상측에 설치된 제 1 스프링(181)과 제 2 스페이서(175)의 하측에 설치된 제 2 스프링(185)을 가진다.The spring 180 has a shape in which a plurality of rings having different diameters are arranged concentrically. The spring 180 has a first spring 181 provided above the first spacer 171 and a second spring 185 provided below the second spacer 175.

상세히 설명하면, 제 1 스프링(181)의 내주면측은 캐리어(150)의 상부측 외주면에 일체로 형성되어 결합되고, 외주면측은 하우징(120)과 제 1 스페이서(171) 사이에 삽입되어 지지 고정된다. 그리고, 제 2 스프링(185)의 내주면측은 캐리어(150)의 하부측 외주면에 일체로 형성되어 결합되고, 외주면측은 베이스(110)와 제 2 스페이서(175) 사이에 삽입되어 지지 고정된다.In detail, the inner circumferential surface side of the first spring 181 is integrally formed and coupled to the outer circumferential surface of the upper side of the carrier 150, and the outer circumferential surface side is inserted between the housing 120 and the first spacer 171 to be fixed. The inner circumferential surface side of the second spring 185 is integrally formed and coupled to the lower outer circumferential surface of the carrier 150, and the outer circumferential surface side is inserted between the base 110 and the second spacer 175 to be fixed.

제 1 스프링(181)과 제 2 스프링(185)은 동일형상 동일구조로 마련되나, 캐리어(150)에 결합되는 위치에 따라 직경에 차이가 있다.Although the first spring 181 and the second spring 185 are provided in the same shape and the same structure, there is a difference in diameter depending on the position coupled to the carrier 150.

캐리어(150)는 사출 성형되고, 스프링(180)은 캐리어(150)의 사출시 내주면측이 캐리어(150)의 외주면에 파묻혀 일체로 형성된다.The carrier 150 is injection molded, and the spring 180 is integrally formed by embedding the inner circumferential surface of the carrier 150 on the outer circumferential surface of the carrier 150.

그런데, 렌즈 구동용 모터의 박형화 및 슬림화에 따라 캐리어(150)의 외주면에 파묻히는 스프링(180)의 내주면측 부위의 면적이 대단히 작다. 그러면, 스프링(180)의 내주면측이 캐리어(150)에서 이탈할 수 있다.However, as the lens driving motor becomes thinner and thinner, the area of the inner circumferential surface side portion of the spring 180 buried in the outer circumferential surface of the carrier 150 is very small. Then, the inner circumferential surface side of the spring 180 can be separated from the carrier 150.

본 실시예에 따른 렌즈 구동용 모터는 스프링(180)이 캐리어(150)로부터 이탈하는 것을 방지할 수 있도록 형성되는데, 이를 도 3a 및 도 3b를 참조하여 설명한다. 도 3a 및 도 3b는 도 1의 "A" 및 "B"부의 확대도이다.The lens driving motor according to the present embodiment is formed to prevent the spring 180 from being separated from the carrier 150, which will be described with reference to FIGS. 3A and 3B. 3A and 3B are enlarged views of portions “A” and “B” of FIG. 1.

도시된 바와 같이, 캐리어(150)의 외주면에 파묻히는 제 1 및 제 2 스프링(181,185)의 내주면측 부위에는 복수의 관통공(181a,185a)이 각각 형성된다. 그러면, 캐리어(150)의 사출시, 캐리어(150)의 외주면측 내측 부위가 관통공(181a,185a)을 통과하여 제 1 및 제 2 스프링(181,185)과 일체로 형성되므로, 제 1 및 제 2 스프링(181,185)은 캐리어(150)로부터 이탈하지 않는다.As shown, a plurality of through holes 181a and 185a are formed in the inner peripheral surface side portions of the first and second springs 181 and 185 embedded in the outer circumferential surface of the carrier 150, respectively. Then, when the carrier 150 is ejected, the inner peripheral side of the carrier 150 is formed integrally with the first and second springs 181 and 185 through the through holes 181a and 185a. The springs 181, 185 do not escape from the carrier 150.

본 실시예에 따른 렌즈 구동용 모터는 제 1 및 제 2 스프링(181,185)의 외주면측에 복수의 지지공(181b,185b)을 각각 형성하고, 하우징(120) 및 베이스(110)에는 지지공(181b,185b)에 삽입되는 지지돌기(123,113)가 각각 형성된다.In the lens driving motor according to the present exemplary embodiment, a plurality of support holes 181b and 185b are formed on the outer circumferential surfaces of the first and second springs 181 and 185, respectively. Support protrusions 123 and 113 inserted into 181b and 185b are formed, respectively.

그러면, 제 1 및 제 2 스프링(181,185)이 하우징(120) 및 베이스(110)의 정해진 부위에 정확하게 각각 결합되고, 하우징(120) 및 베이스(110)상에서 각각 회전하지 않는다. 이로인해, 제 1 및 제 2 스프링(181,185)의 힘이 캐리어(150)의 모든 부위에 균일하게 작용하므로, 캐리어(150)는 정확하고 안정되게 승강운동을 한다.Then, the first and second springs 181, 185 are accurately coupled to the predetermined portions of the housing 120 and the base 110, respectively, and do not rotate on the housing 120 and the base 110, respectively. As a result, the force of the first and second springs 181 and 185 acts uniformly on all parts of the carrier 150, so that the carrier 150 moves up and down accurately and stably.

도 4a 및 도 4b는 본 발명의 다른 실시예에 따른 렌즈 구동용 모터의 요부 확대도로서, 도 3a 및 도 3b와의 차이점만을 설명한다.4A and 4B are enlarged views of main parts of a lens driving motor according to another exemplary embodiment of the present invention, and only the differences from FIGS. 3A and 3B will be described.

도시된 바와 같이, 제 1 및 제 2 스프링(281,285)의 외주면측에 각각 형성된 복수의 지지공(281b,285b)에는 제 1 및 제 2 스페이서(271,275)에 형성된 지지돌기(271a,275a)가 각각 삽입된다.As shown, the support protrusions 271a and 275a formed in the first and second spacers 271 and 275 are respectively formed in the plurality of support holes 281b and 285b formed on the outer circumferential surfaces of the first and second springs 281 and 285, respectively. Is inserted.

이 또한, 제 1 및 제 2 스프링(281,285)이 하우징(220) 및 베이스(210)의 정해진 부위에 정확하게 각각 결합되고, 하우징(220) 및 베이스(210)상에서 각각 회전하지 않으므로, 제 1 및 제 2 스프링(281,285)의 힘이 캐리어(250)의 모든 부위에 균일하게 작용하여 캐리어(250)가 정확하고 안정되게 승강운동을 한다.In addition, since the first and second springs 281 and 285 are precisely coupled to predetermined portions of the housing 220 and the base 210, respectively, and do not rotate on the housing 220 and the base 210, respectively, the first and the second springs. The force of the two springs 281 and 285 acts uniformly on all parts of the carrier 250 so that the carrier 250 moves up and down accurately and stably.
