(8) so that the sprocket wheel (3) and the reciprocating gear (9) mesh with each other,

스프로킷 휠(3)에는 별도의 스토퍼(11)를 위치하여 일방향으로 회전되게 한 것이다.The sprocket wheel (3) is to place a separate stopper 11 to rotate in one direction.

또한, 함체(2)의 양측에는 걸림턱(12)을 형성하여, 통상의 휴대폰(13) 좌우에 형성된 충전기 안치홈(15)과 결합되게 구성한 것이다.In addition, the engaging jaw (12) is formed on both sides of the housing (2), it is configured to be combined with the charger settled groove 15 formed on the left and right of the ordinary mobile phone (13).

이상과 같은 본 발명의 작용을 첨부도면에 의해 보다 상세히 설명하면 다음과 같다.If described in more detail by the accompanying drawings the operation of the present invention as follows.

도 1은 본 발명 휴대폰용 배터리 충전기를 통상의 휴대폰(13)에 결합사용하는 사용상태를 분리도시한 것으로서, 휴대폰(13)의 좌우 양측에 형성된 통상의 충전기 안치홈(15)에 본 발명 충전기의 걸림턱(12)이 서로 삽입되게 하여, 휴대폰과 본 발명 충전기가 밀착되게 고정하는 것이다.1 is a separate view illustrating a state of use of a battery charger for a mobile phone according to the present invention coupled to a conventional mobile phone 13, and the conventional charger settled grooves 15 formed on both left and right sides of the mobile phone 13 of the charger according to the present invention. The locking jaw 12 is inserted into each other, the mobile phone and the charger of the present invention is to be fixed in close contact.

이 상태에서 본 발명 충전기 함체(2)의 일측에 형성된 레버(8)을 누르게 되면, 그 레버(8)의 상부에 형성된 왕복기어(9)가 도 3의 도시와 같이 전진하게 되고, 전진하는 왕복기어(9)에 의해 치합된 스프로킷 휠(3)이 회전하게 되는 것이다.When the lever 8 formed on one side of the charger housing 2 of the present invention is pressed in this state, the reciprocating gear 9 formed on the upper part of the lever 8 is advanced as shown in FIG. The sprocket wheel 3 engaged by the gear 9 is to rotate.

따라서, 스프로킷 휠(3)의 회전작용에 의해 스프로킷 휠(3)의 내주면에 부착된 다수의 자석(4)(4')이 함께 회전하게 되는 것이며, 자석(4)(4')의 회전에 의해 코일체(5)의 내부에는 전기장이 발생되며 그 코일체(5)의 코일 양단부로 전기력을 방출하게 되는 것이다.Therefore, the magnets 4, 4 'attached to the inner circumferential surface of the sprocket wheel 3 rotate together by the rotation of the sprocket wheel 3, and the magnets 4, 4' are rotated together. As a result, an electric field is generated inside the coil body 5 to emit electric force to both ends of the coil of the coil body 5.

따라서, 다수의 자석(4)(4')에 의해 발생된 교류의 전기장은 도 2의 도시와 같이 정류기(14)를 거쳐 외부로 누출된 즉, 휴대폰(13)의 배터리 단자(도면에는 미도시함)와 밀착된 충전기 단자(6)(6')로 직류 전원을 공급하게 되므로, 그 전원에 의해 휴대폰의 배터리가 충전되는 것이다.Thus, the electric field of alternating current generated by the plurality of magnets 4, 4 'leaks out through the rectifier 14 as shown in FIG. 2, i.e., the battery terminal of the mobile phone 13 (not shown in the drawing). And the direct current power supply to the charger terminals 6 and 6 ′ in close contact with each other, thereby charging the battery of the mobile phone.

또한, 전기한 레버(8)는 회전운동을 하되, 함체(2)의 내부로 일정깊이 들어간 상태에서 그 레버(8)를 누르고 있는 압압력을 제거하면, 그 하부의 스프링(7) 복귀력에 의해 원상태로 복귀하므로, 좌우 일정구간 연속적으로 회전시킬 수 있는 것이다.In addition, the lever 8 is rotated, but when the pressure is released while pressing the lever 8 in a state that is deep into the interior of the housing (2), to the return force of the spring (7) By returning to the original state, it is possible to continuously rotate the left and right a certain section.

따라서, 레버(8)의 지속적인 좌우 회전운동과 그 상부에 형성된 왕복기어(9)의 직선운동을 스토퍼(11)에 의해 일방향으로만 회전하는 스프로킷 휠(3)을 연속적으로 회전시키게 되므로 지속적인 자장의 발생이 이루어져 휴대폰 배터리에 전원을연속하여 공급할 수 있는 것이다.Accordingly, the sprocket wheel 3 continuously rotating in one direction by the stopper 11 continuously rotates the left and right rotational movements of the lever 8 and the linear movement of the reciprocating gear 9 formed thereon. It is possible to supply power to the battery of mobile phone continuously.

또한, 그 왕복기어(9)의 작용을 보다 세밀하게 살펴보면, 왕복기어(9)의 일측 즉, 스프로킷 휠(3)과 이격된 측단부에는 별도의 스프링(10)에 의해 탄지되어 있어 그 스프링(10)에 의해 항상 스프로킷 휠(3)을 향해 압압하는 힘을 받고 있는 것이며, 왕복기어(9)의 전진운동에 의해 스프로킷 휠(3)이 일정구간 회전한 상태에서 레버(8)가 후퇴함과 동시에 왕복기어(9)가 후퇴하면 이때에는 그 치형이 서로 경사상으로 치합되므로 그 경사상의 치형을 따라 왕복기어(9)가 스프링(10) 탄지력을 이기고 일정높이 상승하여 원상태로 북귀되는 것이다.In addition, when the action of the reciprocating gear 9 is examined in more detail, one side of the reciprocating gear 9, that is, the side end portion spaced apart from the sprocket wheel 3, is supported by a separate spring 10. 10) is always pressed against the sprocket wheel 3, and the lever 8 is retracted while the sprocket wheel 3 is rotated for a certain period by the forward movement of the reciprocating gear 9. At the same time, if the reciprocating gear 9 is retracted at this time, since the teeth are inclined to each other inclined to each other, the reciprocating gear 9 overcomes the spring 10 holding force along the inclined teeth and rises a predetermined height to return to the original state.

또한, 스프로킷 휠(3)의 치형 주연에 형성된 스토퍼(11)는 스프로킷 휠(3)이 왕복기어(9)의 후퇴시 역회전되는 것을 방지하는 것이다.In addition, the stopper 11 formed on the tooth circumference of the sprocket wheel 3 prevents the sprocket wheel 3 from rotating backward when the reciprocating gear 9 is retracted.

따라서, 사용자는 휴대폰 배터리의 충전량이 없거나, 사용중 배터리 소모음이 들리면 즉시 본 발명 충전기를 장착하여 그 레버(8)를 왕복시켜 자가발전에 의해 휴대폰 배터리에 전원을 공급하므로, 별도의 전원이 없이도 매우 장기간동안 휴대폰을 사용할 수 있는 것이다.Therefore, when the user does not have a charge amount of the mobile phone battery, or hears the battery consumption noise during use, the battery charger is immediately mounted by reciprocating the lever 8 to supply power to the mobile phone battery by self-powering. You can use your phone for a long time.

이상과 같은 본 발명 휴대폰의 휴대용 배터리 충전기는 별도의 전원이 없이도 자가발전 장치에 의해 휴대폰의 배터리 충전이 가능하므로, 산간이나 장기간 외출 및 외부에서 업무를 행하는 경우에도 불편함이 없이 사용이 가능한 것이며, 통화중에도 지속적으로 자가발전장치를 구동하여 휴대폰 배터리에 전원을 공급하므로통화의 중단없이 계속하여 사용이 가능한 효과가 있는 것이다.The portable battery charger of the present invention as described above is capable of charging the battery of the mobile phone by a self-powered device without a separate power source, so that it can be used without any inconvenience even when working in the mountains or going out for a long time or outside. Continuously driving the self-powered device during the call to supply power to the battery of the cell phone has the effect that can be used continuously without interruption.
