그 외 다른 구성을 제1실시예와 동일한 바, 자세한 설명은 생략한다.Other configurations are the same as those in the first embodiment, and detailed description thereof will be omitted.
이하, 상술한 구성으로 이루어진 본 발명의 작동과정에 대하여 살펴본다.Hereinafter, an operation process of the present invention having the above-described configuration will be described.
도 7에 도시된 바와 같이, 상기 개구부(211)가 폐쇄된 상태에서는 상기 판스프링(250)은 상기 제1회전도어(231)와 제2회전도어(235)가 상호 접하도록 탄성력을 부가하고 있고, 상기 제1형상기억합금(240)과 제2형상기억합금(263)에는 전류가 인가되지 않아 이완된 상태로 놓여 있다.As shown in FIG. 7, in the state in which the opening 211 is closed, the leaf spring 250 applies an elastic force so that the first rotating door 231 and the second rotating door 235 contact each other. The first mold restraint alloy 240 and the second mold restraint alloy 263 are placed in a relaxed state because no current is applied.
이때, 상기 폐쇄자석부(280) 즉 상기 제1회전도어(231)에 장착된 제7자석(281)과, 상기 제2회전도어(235)에 장착된 자성체(282)의 상호 접촉에 의해, 상기 제1회전도어(231) 및 제2회전도어(235)는 상호 접하여 상기 개구부(211)를 완전히 폐쇄시키면서 동시에 상호 유동됨이 없이 일정한 위치를 유지한다.At this time, by the mutual contact between the closed magnet portion 280, that is, the seventh magnet 281 attached to the first rotary door 231, and the magnetic body 282 mounted to the second rotary door 235, The first rotating door 231 and the second rotating door 235 are in contact with each other to completely close the opening 211 and at the same time maintains a constant position without flowing to each other.
이러한 상태에서 상기 개구부(211)를 개방하기 위해, 사용자가 별도의 버튼 등을 조작하면, 미도시된 제어부는 상기 제1형상기억합금(240)에 전류를 인가한다.In this state, when the user manipulates a separate button or the like to open the opening 211, the controller (not shown) applies a current to the first shape-retaining alloy 240.
상기 제1형상기억합금(240)에 전류가 되면, 상기 제1형상기억합금(240)은 수축하게 되는바, 상기 제1형상기억합금(240)에 연결된 상기 제1회전도어(231)는 회전하게 되고, 이로 인해 상기 제1회전도어(231)의 제1기어부(232)에 맞물려 있는 상기 제2기어부(236)가 형성된 상기 제2회전도어(235)가 상기 제1회전도어(231)의 반대방향으로 회전하게 된다.When the current of the first mold restraint alloy 240, the first mold restraint alloy 240 is contracted, the first rotary door 231 connected to the first mold restraint alloy 240 is rotated As a result, the second rotation door 235 having the second gear part 236 engaged with the first gear part 232 of the first rotation door 231 is the first rotation door 231. Will rotate in the opposite direction.
상기 제1회전도어(231)와 제2회전도어(235)가 상호 멀어지는 방향으로 회전됨에 따라서, 상기 판스프링(250)은 팽창되고, 상기 개구부(211)는 점점 개방된다.As the first rotary door 231 and the second rotary door 235 are rotated in a direction away from each other, the leaf spring 250 is expanded, and the opening 211 is gradually opened.
상기 제1회전도어(231)가 일정 각도 이상 회전하게 되면, 상기 제1회전도어(231)에 형성된 걸림돌기(233)는 상기 후크부재(261)에 접하게 된다.When the first rotary door 231 is rotated by a predetermined angle or more, the locking protrusion 233 formed on the first rotary door 231 is in contact with the hook member 261.
이러한 상태에서 상기 제1회전도어(231)가 더 회전하면, 상기 후크부재(261)는 상기 걸림돌기(233)에 의해 회전되어 상기 걸림유지스프링(262)을 압축 또는 팽창시키게 된다.In this state, when the first rotary door 231 further rotates, the hook member 261 is rotated by the locking protrusion 233 to compress or expand the locking holding spring 262.
그리고, 상기 걸림돌기(233)가 상기 후크부재(261)를 넘어가게 되면, 압축 또는 팽창되어 있던 상기 걸림유지스프링(262)의 탄성복원력에 의해 상기 후크부재(261)는 역회전하게 되어, 상기 걸림돌기(233)를 걸고 있게 된다.When the locking protrusion 233 crosses the hook member 261, the hook member 261 is reversely rotated by the elastic restoring force of the locking retaining spring 262 that has been compressed or expanded. Hanging projection 233 is hanging.
즉, 상기 판스프링(250)의 탄성력에 의해 상기 제1회전도어(231)는 상기 개구부(211)를 폐쇄하는 방향으로 회전되려고 하지만, 상기 제1회전도어(231)에 형성된 걸림돌기(233)가 상기 후크부재(261)에 걸려 있어 도 8에 도시된 바와 같이 상기 개구부(211)를 개방된 상태로 유지하게 된다.That is, although the first rotating door 231 tries to rotate in the direction of closing the opening 211 by the elastic force of the leaf spring 250, the locking protrusion 233 formed in the first rotating door 231. Is hooked to the hook member 261 to maintain the opening 211 as shown in FIG. 8.
위와 같이 상기 개구부(211)가 개방된 상태를 유지하면, 미도시된 제어부는 상기 제1형상기억합금(240)에 인가된 전류를 차단하여, 상기 제1형상기억합금(240)이 전류에 지속적으로 가열되는 것을 방지한다.When the opening 211 is kept open as described above, the controller (not shown) cuts off the current applied to the first mold restraint alloy 240 so that the first mold restraint alloy 240 continues to the current. To prevent heating.
이때, 상기 개방자석부(270) 즉 상기 제1회전도어(231)에 장착되는 제5자석(271)과, 상기 베이스(210)에 장착되는 자성체(272)의 상호 접촉에 의해, 상기 회전도어(230)는 회전 유동됨이 없이 상기 개구부(211)를 개방된 상태로 유지하게 된다.In this case, the rotary door is formed by the mutual contact between the open magnet portion 270, that is, the fifth magnet 271 mounted on the first rotating door 231, and the magnetic body 272 mounted on the base 210. 230 maintains the opening 211 in an open state without rotation flow.
또한, 상기 판스프링(250)에 유동방지판(251)을 형성함으로써, 상기 유동방지판(251)이 상기 회전도어(230)의 상면 또는 하면과 면접촉을 하게 되는바, 상기 회전도어(230)가 회전하면서 상하방향으로 유동되는 것을 방지할 수 있다.In addition, by forming the flow preventing plate 251 in the leaf spring 250, the flow preventing plate 251 is in surface contact with the upper or lower surface of the rotary door 230, the rotary door 230 ) Can be prevented from flowing in the vertical direction while rotating.
한편, 도 8에 도시된 바와 같이 상기 개구부(211)가 개방된 상태에서 상기 개구부(211)룰 폐쇄하고자 할 경우에는, 미도시된 상기 제어부는 상기 제2형상기억합금(263)에 전류를 인가한다.Meanwhile, when the opening 211 is to be closed in the state in which the opening 211 is opened as shown in FIG. 8, the controller, which is not shown, applies a current to the second shape storage alloy 263. do.
그러면, 상기 제2형상기억합금(263)은 수축하게 되고, 이로 인해 상기 후크부재(261)는 상기 걸림유지스프링(262)이 작용하는 탄성력의 방향과 반대방향으로 회전하게 된다.Then, the second shape-retaining alloy 263 is contracted, so that the hook member 261 is rotated in the direction opposite to the direction of the elastic force acting the holding spring (262).
상기 후크부재(261)가 상기 제2형상기억합금(263)에 의해 회전됨에 따라 상기 후크부재(261)에 걸려 있던 상기 제1회전도어(231)는 팽창된 상기 판스프링(250)의 탄성복원력에 의해 상기 개구부(211)를 폐쇄하는 방향으로 회전된다.As the hook member 261 is rotated by the second mold restraint alloy 263, the first rotating door 231 hanging on the hook member 261 has an elastic restoring force of the expanded leaf spring 250. It rotates in the direction to close the opening 211 by.
이때, 상기 제1회전도어(231)가 상기 개구부(211)를 폐쇄하는 방향으로 회전됨에 따라서, 상기 제1회전도어(231)의 제1기어부(232)와 맞물리는 제2기어부(236)가 형성된 상기 제2회전도어(235)도 상기 개구부(211)를 폐쇄하는 방향을 회전하게 되어, 도 7에 도시된 바와 같이 상기 제1회전도어(231)와 제2회전도어(235)가 상호 접함으로써 상기 개구부(211)를 폐쇄하게 된다.In this case, as the first rotating door 231 is rotated in the direction of closing the opening 211, the second gear part 236 meshing with the first gear part 232 of the first rotating door 231. The second rotating door 235 is also rotated to close the opening 211, as shown in Figure 7 the first rotating door 231 and the second rotating door 235 is By contacting each other, the opening 211 is closed.
또한, 상기 개구부(211)가 완전히 닫히면, 미도시된 상기 제어부는 상기 제2형상기억합금(263)에 인가된 전류를 차단하여 상기 제2형상기억합금(263)이 전류에 지속적으로 가열되는 것을 방지한다.In addition, when the opening 211 is completely closed, the controller (not shown) blocks the current applied to the second mold restraint alloy 263 so that the second mold restraint alloy 263 is continuously heated to the current. prevent.
상기 제1회전도어(231) 및 제2회전도어(235)는 상기 폐쇄자석부(280)에 의해 상호 밀착됨으로써, 상기 개구부(211)를 완전하게 폐쇄할 수 있고, 또한 외력에 의해 쉽게 유동됨이 없이 상기 개구부(211)의 폐쇄상태를 유지할 수 있다.The first rotating door 231 and the second rotating door 235 are in close contact with each other by the closed magnet part 280, thereby completely closing the opening 211, and easily flowed by an external force. Without this, it is possible to maintain the closed state of the opening 211.
위와 같이, 형상기억합금을 이용하여 휴대폰 카메라의 도어를 개폐함으로써, 개폐장치의 두께를 보다 얇게 하여 제품의 슬림화를 이룰 수 있다.As described above, by opening and closing the door of the mobile phone camera using the shape memory alloy, it is possible to achieve a slimmer product by making the thickness of the opening and closing device thinner.

위와 같은 상기 토션스프링(1150)에 의해, 상기 회전도어(1130)는 초기에 상기 형상기억합금(1140)에 의해 상기 토션스프링(1150)을 압축 또는 팽창시키면서 회전하다가, 상기 토션스프링(1150)의 최대변곡점을 지나면, 압축 또는 팽창된 상기 토션스프링(1150)의 탄성복원력에 의해 상기 회전도어(1130)는 나머지 구간을 자동으로 회전하게 된다.By the torsion spring 1150 as described above, the rotary door 1130 is initially rotated while compressing or expanding the torsion spring 1150 by the shape memory alloy 1140, the torsion spring 1150 After the maximum inflection point, the rotary door 1130 is automatically rotated by the elastic restoring force of the torsion spring 1150 is compressed or expanded.
이를 위해, 도 14에 도시된 바와 같이, 상기 회전도어(1130)의 회전중심(D1)과 상기 토션스프링(1150)의 타단을 연결한 제1직선(L1)과, 상기 토션스프링(1150)의 회전중심(T1)인 일단과 타단을 연결한 제2직선(L2)은, 그 길이가 상이하다.To this end, as shown in FIG. 14, the first straight line L1 connecting the center of rotation D1 of the rotary door 1130 and the other end of the torsion spring 1150, and the torsion spring 1150 of the The length of the 2nd straight line L2 which connected the one end and the other end which are rotation centers T1 differs.
또한, 상기 회전도어(1130)의 회전궤적(D2)과, 상기 회전도어(1130)에 대한 미구속 상태에서의 상기 토션스프링(1150)의 회전궤적(T2)은, 상호 2점 즉 도 14에서 P1 및 P2에서 교차된다.In addition, the rotational track D2 of the rotary door 1130 and the rotational track T2 of the torsion spring 1150 in an unconstrained state with respect to the rotary door 1130 are two points, that is, in FIG. 14. Intersect at P1 and P2.
상기 회전도어(1130)에 대한 미구속 상태에서의 상기 토션스프링(1150)의 회전궤적(T2)이란, 상기 토션스프링(1150)이 상기 회전도어(1130)에 결합되지 않은 상태에서 상기 토션스프링(1150)의 일단을 회전중심(T1)으로 하여 회전할 때의 회전궤적을 말한다.The rotational track T2 of the torsion spring 1150 in the unrestrained state with respect to the rotary door 1130 is the torsion spring 1150 without the torsion spring 1150 coupled to the rotary door 1130. It refers to the rotational track when rotating one end of the (1150) as the center of rotation (T1).
본 실시예에서는, 상기 회전도어(1130)의 회전중심(D1)과 상기 토션스프링(1150)의 타단 사이에 상기 토션스프링(1150)의 일단 즉 회전중심(T1)이 배치되도록 하였다.In this embodiment, one end of the torsion spring 1150, that is, the center of rotation T1, is disposed between the center of rotation D1 of the rotary door 1130 and the other end of the torsion spring 1150.

상기 베이스(1210), 커버(1220), 형상기억합금(1240), 제어부 등은 제 3실시예와 동일한 바, 자세한 설명은 생략한다.The base 1210, the cover 1220, the shape memory alloy 1240, the control unit and the like are the same as the third embodiment, detailed description thereof will be omitted.
상기 회전도어(1230)는, 제1회전도어(1231)와 제2회전도어(1235)로 이루어진다.The rotary door 1230 is composed of a first rotary door 1231 and a second rotary door 1235.
상기 제1회전도어(1231)는, 상기 베이스(1210)에 힌지결합되고, 일단에 제1기어부(1232)가 형성되어 있다.The first rotating door 1231 is hinged to the base 1210 and has a first gear part 1232 formed at one end thereof.
상기 제2회전도어(1235)는, 상기 베이스(1210)에 힌지결합되고, 일단에 상기 제1기어부(1232)와 맞물리는 제2기어부(1236)가 형성되어 있다.The second rotating door 1235 is hinged to the base 1210 and has a second gear part 1236 engaged with the first gear part 1232 at one end thereof.
상기 제1회전도어(1231)와 제2회전도어(1235)는 상기 제1기어부(1232)와 제2기어부(1236)의 맞물림 회전에 의해, 각각 상기 개구부(1211)의 절반씩을 개폐하여, 전체적으로 상기 개구부(1211)를 개폐하게 된다.The first rotating door 1231 and the second rotating door 1235 open and close half of the opening 1211 by engaging rotation of the first gear part 1232 and the second gear part 1236. The opening 1211 is opened and closed as a whole.
즉, 상기 제1회전도어(1231)와 제2회전도어(1235)는 상호 접하여 상기 개구부(1211)를 폐쇄하고, 상호 반대방향으로 회전하여 상기 개구부(1211)를 개방한다.That is, the first rotating door 1231 and the second rotating door 1235 are in contact with each other to close the opening 1211 and rotate in opposite directions to open the opening 1211.
상기 형상기억합금(1240)은 상기 개구부(1211)를 개방할 때 이용되는 제1형상기억합금(1241)과, 상기 개구부(1211)를 폐쇄할 때 이용되는 제2형상기억합금(1242)으로 이루어진다.The shape memory alloy 1240 includes a first shape memory alloy 1241 used to open the opening 1211 and a second shape memory alloy 1242 used to close the opening 1211. .
상기 제1형상기억합금(1241) 및 제2형상기억합금(1242)은 상기 제1회전도어(1231)의 회전중심(D3)과 다른 위치에서 상기 제1회전도어(1231)에 연결된다.The first mold keeping alloy 1241 and the second mold keeping alloy 1242 are connected to the first rotating door 1231 at a position different from the center of rotation D3 of the first rotating door 1231.
상기 토션스프링(1250)은 일단이 상기 베이스(1210)에 힌지결합되고, 타단이 상기 제1회전도어(1231)에 힌지결합되어, 상기 제1회전도어(1231)의 회전시 탄성력을 부가하여 상기 제1회전도어(1231) 및 제2회전도어(1235)의 회전을 돕는다.One end of the torsion spring 1250 is hinged to the base 1210, and the other end is hinged to the first rotating door 1231, thereby adding elastic force when the first rotating door 1231 rotates. Help the rotation of the first rotary door 1231 and the second rotary door 1235.
도 20에 도시된 바와 같이, 상기 제1회전도어(1231)의 회전중심(D3)과 상기 토션스프링(1250)의 타단을 연결한 제1직선(L3)과, 상기 토션스프링(1250)의 회전중심(T3)인 일단과 타단을 연결한 제2직선(L4)은, 그 길이가 상이하다.As shown in FIG. 20, the first straight line L3 connecting the center of rotation D3 of the first rotary door 1231 and the other end of the torsion spring 1250 and the rotation of the torsion spring 1250 are rotated. The length of the 2nd straight line L4 which connected the one end and the other end which are center T3 differs.
또한, 상기 제1회전도어(1231)의 회전궤적(D4)과, 상기 제1회전도어(1231)에 대한 미구속 상태에서의 상기 토션스프링(1250)의 회전궤적(T4)은, 상호 2점 즉 도 20에서 P3 및 P4에서 교차된다.In addition, the rotational track D4 of the first rotating door 1231 and the rotational track T4 of the torsion spring 1250 in an unconstrained state with respect to the first rotating door 1231 are two points each other. Ie intersect at P3 and P4 in FIG.
상기 제1회전도어(1231)에 대한 미구속 상태에서의 상기 토션스프링(1250)의 회전궤적(T4)이란, 상기 토션스프링(1250)이 상기 제1회전도어(1231)에 결합되지 않은 상태에서 상기 토션스프링(1250)의 일단을 회전중심(T3)으로 하여 회전할 때의 회전궤적을 말한다.The rotational track T4 of the torsion spring 1250 in the unrestrained state with respect to the first rotation door 1231 is a state in which the torsion spring 1250 is not coupled to the first rotation door 1231. It refers to the rotational track when rotating one end of the torsion spring 1250 as the rotation center (T3).
본 실시예에서는, 상기 토션스프링(1250)의 회전중심(T3)인 일단과 타단 사이에 상기 제1회전도어(1231)의 회전중심(D3)이 배치되도록 하였다.In the present embodiment, the rotation center D3 of the first rotation door 1231 is disposed between one end and the other end of the rotation center T3 of the torsion spring 1250.
따라서, 도 20에 도시된 바와 같이, 상기 제1회전도어(1231)의 회전궤적(D4)과, 상기 제1회전도어(1231)에 대한 미구속 상태에서의 상기 토션스프링(1250)의 회전궤적(T4)은, 상호 2점에서 교차하고, 상기 제1회전도어(1231)의 회전궤적(D4)이 상기 토션스프링(1250)의 회전궤적(T4) 밖으로 돌출되어 있다.Therefore, as shown in FIG. 20, the rotational track D4 of the first rotation door 1231 and the rotational trajectory of the torsion spring 1250 in an unconstrained state with respect to the first rotation door 1231. T4 intersects at two points, and the rotational track D4 of the first rotary door 1231 protrudes out of the rotational track T4 of the torsion spring 1250.
그러나, 상기 토션스프링(1250)의 타단은 상기 제1회전도어(1231)에 결합되어 구속되기 때문에, 상기 토션스프링(1250)은 상기 제1회전도어(1231)의 회전궤적(D4)을 따라서 이동하게 되고, 이로 인해 상기 토션스프링(1250)은 초기에 팽창되게 된다.However, since the other end of the torsion spring 1250 is coupled to and constrained to the first rotation door 1231, the torsion spring 1250 moves along the rotation trajectory D4 of the first rotation door 1231. As a result, the torsion spring 1250 is initially expanded.
즉, 상기 형상기억합금(1240)에 의해 상기 제1회전도어(1231)가 회전될 때 상기 토션스프링(1250)은 일단을 회전중심(T3)으로 회전하면서 팽창되다가, 상기 토션스프링(1250)의 최대변곡점을 지나면, 팽창된 상기 토션스프링(1250)의 탄성복원력에 의해 상기 제1회전도어(1231)는 나머지 구간을 회전하게 된다.That is, when the first rotation door 1231 is rotated by the shape memory alloy 1240, the torsion spring 1250 is expanded while rotating one end to the rotation center T3, and the torsion spring 1250 of the torsion spring 1250 is rotated. After the maximum inflection point, the first rotating door 1231 rotates the remaining section by the elastic restoring force of the expanded torsion spring (1250).

The magnetic body 1272 in contact with the fifth magnet 1271 and the seventh magnet 1281 was mounted.
즉, 상기 제5자석(1271)과 자성체(1272)의 접촉에 의해 상기 제1회전도어(1231)는 상기 개구부(1211)를 개방한 상태로 유동됨이 없이 고정된다.That is, the first rotating door 1231 is fixed without flowing in the state in which the opening 1211 is opened by the contact between the fifth magnet 1271 and the magnetic body 1272.
상기 제1회전도어(1231)가 유동됨이 없이 고정됨으로써, 상기 제1회전도어(1231)와 제1기어부(1232) 및 제2기어부(1236)로 맞물려 있는 상기 제2회전도어(1235)가 유동됨이 없이 고정된 상태를 유지한다.As the first rotary door 1231 is fixed without being flown, the second rotary door 1235 meshes with the first rotary door 1231, the first gear part 1232, and the second gear part 1236. ) Remains fixed without flow.

그 외 다른 구성을 제 3실시예와 동일한 바, 자세한 설명은 생략한다.Other configurations are the same as those in the third embodiment, and detailed description thereof will be omitted.
이하, 상술한 구성으로 이루어진 본 발명의 작동과정에 대하여 살펴본다.Hereinafter, an operation process of the present invention having the above-described configuration will be described.
도 17에 도시된 바와 같이, 상기 개구부(1211)가 폐쇄된 상태에서는 상기 토션스프링(1250)은 이완된 상태를 유지하고 있고, 상기 제1형상기억합금(1241)과 제2형상기억합금(1242)에는 전류가 인가되지 않아 이완된 상태로 놓여 있다.As shown in FIG. 17, in the state in which the opening 1211 is closed, the torsion spring 1250 is in a relaxed state, and the first mold restraint alloy 1241 and the second mold restraint alloy 1242 are shown in FIG. ) Is in a relaxed state because no current is applied.
이때, 상기 폐쇄자석부(1280) 즉 상기 제1회전도어(1231)에 장착된 제7자석(1281)과, 상기 제2회전도어(1235)에 장착된 자성체(1282)의 상호 접촉에 의해, 상기 제1회전도어(1231) 및 제2회전도어(1235)는 상호 접하여 상기 개구부(1211)를 완전히 폐쇄시키면서 동시에 상호 유동됨이 없이 일정한 위치를 유지한다.In this case, by the mutual contact between the seventh magnet (1281) attached to the closed magnet portion 1280, that is, the first rotary door 1231, and the magnetic body (1282) mounted on the second rotary door (1235), The first rotating door 1231 and the second rotating door 1235 are in contact with each other to completely close the opening 1211 and at the same time maintain a constant position without flowing to each other.
이러한 상태에서 상기 개구부(1211)를 개방하기 위해, 사용자가 별도의 버튼 등을 조작하면, 상기 제어부는 상기 제1형상기억합금(1241)에 전류를 인가한다.In this state, when the user manipulates a separate button or the like to open the opening 1211, the controller applies a current to the first shape-retaining alloy 1241.
상기 제1형상기억합금(1241)에 전류가 되면, 상기 제1형상기억합금(1241)은 수축하게 되는바, 상기 제1형상기억합금(1241)에 연결된 상기 제1회전도어(1231)는 회전하게 되고, 이로 인해 상기 제1회전도어(1231)의 제1기어부(1232)에 맞물려 있는 상기 제2기어부(1236)가 형성된 상기 제2회전도어(1235)가 상기 제1회전도어(1231)의 반대방향으로 회전하게 된다.When the first mold holding alloy 1241 is current, the first mold holding alloy 1241 is contracted, and the first rotary door 1231 connected to the first mold holding alloy 1241 is rotated. As a result, the second rotating door 1235 having the second gear part 1236 engaged with the first gear part 1232 of the first rotating door 1231 is the first rotating door 1231. Will rotate in the opposite direction.
이때, 상기 토션스프링(1250)은 타단이 상기 제1회전도어(1231)에 구속되어 있는바, 일단을 중심으로 상기 제1회전도어(1231)의 궤적을 따라 회전하게 된다.At this time, the other end of the torsion spring 1250 is constrained to the first rotation door 1231, and rotates along the trajectory of the first rotation door 1231 about one end.
상기 제1회전도어(1231)와 제2회전도어(1235)가 상호 멀어지는 방향으로 회전됨에 따라서, 상기 토션스프링(1250)은 팽창되고, 상기 개구부(1211)는 점점 개방된다.As the first rotating door 1231 and the second rotating door 1235 are rotated in a direction away from each other, the torsion spring 1250 expands, and the opening 1211 gradually opens.
도 18은 상기 토션스프링(1250)이 최대변곡점에 도달한 상태를 도시한 것으로써, 이때까지 상기 제1형상기억합금(1241)은 상기 제1회전도어(1231)를 회전시키고, 상기 토션스프링(1250)은 팽창된다.FIG. 18 illustrates a state in which the torsion spring 1250 reaches the maximum inflection point. The first shape-retaining alloy 1241 rotates the first rotation door 1231 and the torsion spring 12 up to this point. 1250 is expanded.
도 18에 도시된 상기 토션스프링(1250)의 최대변곡점을 지나면, 그 후부터는 팽창되어 있던 상기 토션스프링(1250)의 탄성복원력에 의해 상기 제1회전도어(1231) 및 제2회전도어(1235)는 나머지 구간을 회전하여, 도 19에 도시된 바와 같이 상기 개구부(1211)를 완전히 개방한 상태가 된다.After the maximum inflection point of the torsion spring 1250 shown in FIG. 18, the first rotary door 1231 and the second rotary door 1235 are formed by the elastic restoring force of the torsion spring 1250 which has been inflated thereafter. By rotating the remaining section, the opening 1211 is completely opened as shown in FIG. 19.
한편, 상기 제어부는 상기 토션스프링(1250)의 최대변곡점을 지나는 시점에서 상기 제1형상기억합금(1241)에 인가된 전류를 차단하여 상기 제1형상기억합금(1241)을 이완시킴으로써, 상기 회전도어(1230)가 원활하게 나머지 구간을 회전되도록 하고, 또한 상기 제1형상기억합금(1241)이 전류에 지속적으로 가열되는 것을 방지한다.On the other hand, the control unit blocks the current applied to the first mold-type storage alloy 1241 at the point of time passing the maximum inflection point of the torsion spring (1250) to relax the first mold-type storage alloy 1241, the rotary door The 1230 smoothly rotates the remaining sections, and also prevents the first shape-retaining alloy 1241 from being continuously heated to the current.
이때, 상기 개방자석부(1270) 즉 상기 제1회전도어(1231)에 장착되는 제5자석(1271)과, 상기 베이스(1210)에 장착되는 자성체(1272)의 상호 접촉에 의해, 상기 회전도어(1230)는 회전 유동됨이 없이 상기 개구부(1211)를 개방된 상태로 유지하게 된다.In this case, the rotary door is formed by mutual contact between the open magnet part 1270, that is, the fifth magnet 1271 mounted on the first rotating door 1231, and the magnetic material 1272 mounted on the base 1210. 1230 maintains the opening 1211 in an open state without rotational flow.
그리고, 도 19에 도시된 바와 같이 상기 개구부(1211)가 개방된 상태에서 상기 개구부(1211)룰 폐쇄하고자 할 경우에는, 상기 제어부는 상기 제2형상기억합금(1242)에 전류를 인가한다.As shown in FIG. 19, when the opening 1211 is to be closed while the opening 1211 is open, the control unit applies a current to the second shape storage alloy 1242.
그러면, 상기 제2형상기억합금(1242)은 수축하게 되고, 상기 제2형상기억합금(1242)에 연결된 상기 제1회전도어(1231)는 상기 토션스프링(1250)을 도 18에 도시된 바와 같은 상태가 될 때까지 팽창시키면서 회전하게 된다.Then, the second mold restraint alloy 1242 is contracted, and the first rotating door 1231 connected to the second mold restraint alloy 1242 may move the torsion spring 1250 as shown in FIG. 18. It rotates while expanding until it is in a state.
이때, 상기 토션스프링(1250)은 타단이 상기 제1회전도어(1231)에 구속되어 있는바, 일단을 중심으로 상기 제1회전도어(1231)의 궤적을 따라 회전하게 된다.At this time, the other end of the torsion spring 1250 is constrained to the first rotation door 1231, and rotates along the trajectory of the first rotation door 1231 about one end.
도 18은 상기 토션스프링(1250)이 최대변곡점에 도달한 상태를 도시한 것으로써, 이때까지 상기 제2형상기억합금(1242)은 상기 제1회전도어(1231) 및 제2회전도어(1235)를 회전시키고, 상기 토션스프링(1250)은 팽창된다.FIG. 18 illustrates a state in which the torsion spring 1250 reaches a maximum inflection point, and the second shape-retaining alloy 1242 is formed of the first rotating door 1231 and the second rotating door 1235. The torsion spring 1250 is inflated.
도 18에 도시된 상기 토션스프링(1250)의 최대변곡점을 지나면, 그 후부터는 팽창되어 있던 상기 토션스프링(1250)의 탄성복원력에 의해 상기 회전도어(1230)는 나머지 구간을 회전하여 도 17에 도시된 바와 같이 상기 개구부(1211)를 완전히 폐쇄한 상태가 된다.After passing the maximum inflection point of the torsion spring 1250 shown in FIG. 18, the rotary door 1230 rotates the remaining section by the elastic restoring force of the torsion spring 1250 which has been inflated thereafter. As described above, the opening 1211 is completely closed.
이때, 상기 제1회전도어(1231)가 상기 개구부(1211)를 폐쇄하는 방향으로 회전됨에 따라서, 상기 제1회전도어(1231)의 제1기어부(1232)와 맞물리는 제2기어부(1236)가 형성된 상기 제2회전도어(1235)도 상기 개구부(1211)를 폐쇄하는 방향을 회전하게 되어, 도 17에 도시된 바와 같이 상기 제1회전도어(1231)와 제2회전도어(1235)가 상호 접함으로써 상기 개구부(1211)를 폐쇄하게 된다.In this case, as the first rotating door 1231 is rotated in the direction of closing the opening 1211, the second gear part 1236 meshes with the first gear part 1232 of the first rotating door 1231.
