도 1은 본 발명의 일 실시예에 따른 진동모터의 개략적 구성을 보인 도로서, 이를 설명한다.1 is a view showing a schematic configuration of a vibration motor according to an embodiment of the present invention, it will be described.

진동모터(100)는 양측면이 개방된 원통형의 케이스(110)를 구비한다. 케이스(110)는 상호 소정 간격을 가지는 내측케이스(112)와 외측케이스(114)를 가지고, 내측케이스(112)와 외측케이스(114)는 연결테(116)에 의하여 일체로 결합된다. 연결테(116)는 내측케이스(112)와 외측케이스(114)의 개방부측 일 단면(端面)에만 마련되는데, 이는 내측케이스(112)와 외측케이스(114) 사이의 공간에 다수의 부품을 설치할 수 있도록 하기 위함이다. 그리고, 외측케이스(114)는 내측케이스(112) 보다 더 길게 마련된다.Vibration motor 100 has a cylindrical case 110 of which both sides are open. The case 110 has an inner case 112 and an outer case 114 having a predetermined distance from each other, the inner case 112 and the outer case 114 are integrally coupled by a connecting frame 116. The connection frame 116 is provided only at one end surface of the inner side of the inner case 112 and the outer case 114, which is to install a plurality of parts in the space between the inner case 112 and the outer case 114. To do so. The outer case 114 is provided longer than the inner case 112.

내측케이스(112)의 양단부측 내주면에는 베어링(121)이 지지되어 설치되고, 베어링(121)에는 축(123)이 지지된다. 이때, 축(123)의 일단부측은 케이스(110)의 외측으로 노출되게 설치된다. 케이스(110)의 내부에 위치된 축(123)의 단부측에는 축(123)이 케이스(110)의 내ㆍ외측으로 유동되는 것을 방지하기 위한 부시(125)가 설치된다.The bearing 121 is supported and installed on the inner peripheral surfaces of both ends of the inner case 112, and the shaft 123 is supported by the bearing 121. At this time, one end side of the shaft 123 is installed to be exposed to the outside of the case 110. On the end side of the shaft 123 located inside the case 110, a bush 125 is installed to prevent the shaft 123 from flowing into and out of the case 110.

부시(125)가 설치된 축(123)의 부위에는 일체로 성형된 정류자(131)와 권선홀더(133)가 압입되고, 권선홀더(133)의 외주면에는 코일(135)이 접착된다. 이때,코일(135)은 내측케이스(112)와 외측케이스(114)의 사이의 공간에 위치됨과 동시에, 외측케이스(114)의 내주면과 인접되게 설치된다. 그리고, 내측케이스(112)의 외주면에는 코일(135)과 대향되게 마그네트(141)가 접착된다.The commutator 131 and the winding holder 133 which are integrally formed are pressed into a portion of the shaft 123 where the bush 125 is installed, and the coil 135 is bonded to the outer circumferential surface of the winding holder 133. At this time, the coil 135 is located in the space between the inner case 112 and the outer case 114, and is installed adjacent to the inner peripheral surface of the outer case 114. The magnet 141 is bonded to the outer circumferential surface of the inner case 112 to face the coil 135.

외측케이스(114)의 타 단면(端面)측에는 브러쉬홀더(151)가 압입되고, 브러쉬홀더(151)에는 코일(135)로 전류를 공급하는 브러쉬(153)가 고정되며, 브러쉬(153)에는 외부의 전원과 연결된 전선(155)이 접속된다. 그리고, 케이스(110)의 외측으로 노출된 축(123)의 부위에는 편심추(160)가 압입된다. 편심추(160)는 축(123)의 회전시 동일하게 회전되면서 진동을 발생한다.The brush holder 151 is press-fitted to the other end surface side of the outer case 114, and the brush holder 151 is fixed with a brush 153 for supplying current to the coil 135, and the brush 153 is external The wire 155 is connected to the power supply of. In addition, the eccentric weight 160 is press-fitted into the portion of the shaft 123 exposed to the outside of the case 110. The eccentric weight 160 rotates in the same manner as the shaft 123 rotates to generate vibration.

이상에서 설명하듯이, 본 발명에 따른 진동모터는 베어링 및 마그네트를 지지하는 내측케이스가 외측케이스와 일체로 형성된다. 그러므로, 베어링 및 마그네트를 지지하는 별도의 부품을 마련할 필요가 없으므로 부품수가 감소한다. 또, 내측케이스를 외측케이스에 조립하기 위한 조립공정이 필요 없으므로, 조립공수가 감소한다. 이로인해, 원가가 절감된다.As described above, in the vibration motor according to the present invention, the inner case supporting the bearing and the magnet is formed integrally with the outer case. Therefore, the number of parts is reduced because there is no need to provide separate parts for supporting the bearing and the magnet. In addition, since the assembly process for assembling the inner case to the outer case is not necessary, the assembly labor is reduced. This saves cost.

이상에서는, 본 발명의 일 실시예에 따라 본 발명을 설명하였지만, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 변경 및 변형한 것도 본 발명에 속함은 당연하다.In the above, the present invention has been described in accordance with one embodiment of the present invention, but those skilled in the art to which the present invention pertains have been changed and modified without departing from the spirit of the present invention. Of course.
