본체(10)에 장착되는 제1경첩(12)이 고정되는 제1고정홈(13)과, 외주연 일측에 형성되는 제1베벨기어(14)를 포함하는 제1구동축(15);a first drive shaft 15 including a first fixing groove 13 to which a first hinge 12 mounted on the body 10 is fixed, and a first bevel gear 14 formed on one side of the outer periphery;

제1구동축(15)과 대향되게 디스플레이부(11)에 장착되는 제2경첩(16)이 고정되는 제2고정홈(17)과, 외주연 일측에 형성되는 제2베벨기어(18)를 포함하는 제2구동축(19);It includes a second fixing groove 17 in which a second hinge 16 mounted on the display unit 11 opposite to the first drive shaft 15 is fixed, and a second bevel gear 18 formed on one side of the outer periphery. a second drive shaft 19;

제1베벨기어(14)와 제2베벨기어(18)에 치합되는 제3베벨기어(20)가 양단에 형성되는 연동축(21)(즉, 제1,2구동축(15,19)과 연동축(21)은 90도 방향을 유지하도록 형성됨);을 구비하되,The third bevel gear 20 meshed with the first bevel gear 14 and the second bevel gear 18 is interlocked with the interlocking shaft 21 (that is, the first and second drive shafts 15 and 19) formed at both ends. The shaft 21 is formed to maintain a 90 degree direction);

본체(10)와 디스플레이부(11)를 임의각도 범위내에서 상대 접철시킬 경우, 제1,2구동축(15,19) 중 어느 하나가 정방향 또는 역방향으로 회전운동을 하게 되고, 연동되는 제3베벨기어(20)에 의해 제1,2구동축(15,19) 중 다른 하나를 동시에 반대방향으로 동일속도로 회전운동시키는 것을 특징으로 한다.When the main body 10 and the display unit 11 are relatively folded within an angle range, any one of the first and second drive shafts 15 and 19 rotates in the forward or reverse direction, and the third bevel is interlocked. It is characterized in that the other one of the first and second drive shafts 15 and 19 is rotated at the same speed in the opposite direction at the same time by the gear 20.

더욱 바람직한 실시예에 의하면, 도 1, 도 2(a,b), 도 3에서와 같이, 전술한 연동축(21)은 일측에 연동축(21)이 회전가능하게 결합되고, 타측에 제1,2구동축(15,19)의 연장축(22,23)이 회전가능하게 각각 끼워맞춤되는 결합보스(24)가 형성되는 고정블록(25);을 더 구비하여,According to a more preferred embodiment, as in Figs. 1, 2 (a, b), and Fig. 3, the above-mentioned interlocking shaft 21 is rotatably coupled to the interlocking shaft 21 on one side, and the first interlocking shaft 21 on the other side. , A fixing block 25 in which a coupling boss 24 to which the extension shafts 22 and 23 of the two driving shafts 15 and 19 are rotatably fitted, respectively, is formed;

이로 인해, 전술한 본체(10) 및 디스플레이부(15)를 임의각도로 상대 접철시킬 경우 케이싱(26)에 의해 제1,2구동축(15,19) 및 고정블록(25)을 수용하여 감싸게 되므로 2축힌지구조물의 외관이 깔끔하고 이들을 외부로부터 보호할 수 있게 된다.For this reason, when the aforementioned body 10 and the display unit 15 are relatively folded at an arbitrary angle, the first and second drive shafts 15 and 19 and the fixing block 25 are accommodated and wrapped by the casing 26 . The appearance of the two-axis hinge structure is neat and it is possible to protect them from the outside.

이하에서, 본 명세서의 일 실시예에 따른 베벨기어방식 2축 힌지구조물이 구비되는 전자기기를 첨부도면에 따라 설명한다.Hereinafter, an electronic device provided with a bevel gear type two-axis hinge structure according to an embodiment of the present specification will be described with reference to the accompanying drawings.

도 1 내지 도 7에서와 같이, 전술한 전술한 본체(10) 및 디스플레이부(11)를 상대 접철시킬 경우, 전술한 본체(10)와 디스플레이부(11)의 접철각도가 0도 또는360도 각도를 유지하는 경우에 본체(10) 및 디스플레이부(11)에 장착된 제1,2경첩(12,16)이 수평상태를 유지하게 된다.As in FIGS. 1 to 7 , when the aforementioned body 10 and the display unit 11 are relatively folded, the folding angle between the aforementioned body 10 and the display unit 11 is 0 degrees or 360 degrees. When maintaining the angle, the first and second hinges 12 and 16 mounted on the main body 10 and the display unit 11 maintain a horizontal state.

전술한 본체(10)와 디스플레이부(11)의 접철각도를 90도에서 270도 각도로 점진적으로 확대시킬 경우에, 제1,2경첩(12,16)이 90도, 180도, 270도로 회전하게 되며, 이때 본체(10) 및 디스플레이부(11)에 장착되는 제1,2구동축(15,19)에 형성된 제1베벨기어(14) 또는 제2베벨기어(18)가 서로 반대방향으로 회전운동을 하게 되고, 동시에 제3베벨기어(20)를 연동시키게 된다.When the above-described folding angle of the main body 10 and the display unit 11 is gradually expanded from 90 degrees to 270 degrees, the first and second hinges 12 and 16 are rotated by 90 degrees, 180 degrees, and 270 degrees. At this time, the first bevel gear 14 or the second bevel gear 18 formed on the first and second drive shafts 15 and 19 mounted on the main body 10 and the display unit 11 rotate in opposite directions. The movement is performed, and the third bevel gear 20 is interlocked at the same time.

즉, 도 2(a)에서와 같이, 본체(10) 또는 디스플레이부(11)를 상대 접철시 제1베벨기어(14)가 역방향(반시계 방향)으로 회전되고 제2베벨기어(18)가 정방향(시계 방향)으로 회전될 경우, 제3베벨기어(30)는 역방향으로 회전하게 된다. That is, as in Fig. 2(a), when the main body 10 or the display unit 11 is relatively folded, the first bevel gear 14 is rotated in the reverse direction (counterclockwise) and the second bevel gear 18 is When rotating in the forward direction (clockwise), the third bevel gear 30 rotates in the reverse direction.

이와 반면에, 도 2(b)에서와 같이, 본체(10) 또는 디스플레이부(11)를 상대 접철시 제1베벨기어(14)가 정방향(시계 방향)으로 회전되고 제2베벨기어(18)가 역방향(반시계 방향)으로 회전될 경우, 제3베벨기어(30)는 정방향으로 회전하게 된다. On the other hand, as shown in Fig. 2(b), when the main body 10 or the display unit 11 is relatively folded, the first bevel gear 14 is rotated in the forward direction (clockwise) and the second bevel gear 18 is rotated. When is rotated in the reverse direction (counterclockwise direction), the third bevel gear 30 rotates in the forward direction.

전술한 바와 같이, 전술한 본체(10)와 디스플레이부(11)에 일체형으로 고정된 제1,2경첩(12,16)이 제1,2구동축(15,19)의 제1,2고정홈(13,17)에 고정되고, 제1,2구동축(15,19)의 제1,2베벨기어(14,18)와 연동축(21)의 제3베벨기어(20)(제1베벨기어(14) 또는 제2베벨기어(18)에 의해 연동됨)를 치합시킴에 따라, 본체(10) 또는 디스플레이부(11)를 상대 접철시킬 경우 제1,2구동축(15,19) 및 연동축(21)이 동시에 연동되어 회전하게 된다. As described above, the first and second hinges 12 and 16 integrally fixed to the main body 10 and the display unit 11 described above are the first and second fixing grooves of the first and second drive shafts 15 and 19. (13,17), the first and second bevel gears 14 and 18 of the first and second drive shafts 15 and 19, and the third bevel gear 20 of the interlocking shaft 21 (the first bevel gear) (14) or interlocked by the second bevel gear 18), when the main body 10 or the display unit 11 is relatively folded, the first and second drive shafts 15 and 19 and the interlocking shaft (21) is interlocked and rotates at the same time.

즉, 전술한 제1,2구동축(15,19) 중 어느 하나가 회전될 경우, 제1구동축(15) 또는 제2구동축(19)의 제1베벨기어(14) 또는 제2베벨기어(18)가 회전하게 되고, 제1,2베벨기어(14,18)와 치합된 제3베벨기어(20)가 회전됨에 따라, 제1,2구동축(15,19) 중 다른 하나를 반대방향으로 회전시키게 된다.That is, when any one of the aforementioned first and second drive shafts 15 and 19 is rotated, the first bevel gear 14 or the second bevel gear 18 of the first drive shaft 15 or the second drive shaft 19 is rotated. ) is rotated, and as the third bevel gear 20 meshed with the first and second bevel gears 14 and 18 is rotated, the other one of the first and second drive shafts 15 and 19 is rotated in the opposite direction will make it

이때, 제1,2구동축(15,19)은 회전방향이 반대인 반면에, 동일 속도를 유지하게 되므로 본체(10) 또는 디스플레이부(11)를 임의각도로 상대 접철시킬 수 있게 된다.At this time, the first and second drive shafts 15 and 19 have opposite rotational directions, but maintain the same speed, so that the main body 10 or the display unit 11 can be relatively folded at an arbitrary angle.

여기에서, 전술한 본 명세서에서는 바람직한 실시예를 참조하여 설명하였지만, 해당 기술분야에서 숙련된 당업자는 하기의 청구범위에 기재된 본 명세서의 사상 및 영역으로부터 벗어나지 않는 범위 내에서 본 명세서를 다양하게 수정 및 변경할 수 있음을 이해할 수 있을 것이다.Here, although the foregoing specification has been described with reference to preferred embodiments, those skilled in the art can variously modify and modify the present specification without departing from the spirit and scope of the present specification as set forth in the following claims.
