It is about the hinge structure of a mobile phone.

일반적으로, 록힌지는 고정축, 가동축, 용수철의 3부품으로 구성되어 있고, 용수철은 약간의 조임장치를 가지고 고정축, 가동축에 부착되어 있으며, 고정축을 고정하여 용수철을 되감기 방향으로 가동축을 돌릴 경우, 작은힘으로 돌릴 수 있는 원리를 이용한 것이다.In general, the lock hinge is composed of three parts: a fixed shaft, a movable shaft, and a spring, and the spring is attached to the fixed shaft and the movable shaft with a slight tightening device, and the movable shaft is fixed to rewind the spring by fixing the fixed shaft. If you turn, you use a principle that can be turned with a small force.

이러한 구조의 록힌지는 심플하고 고정이 적고, 각도조절이 용이하여 일반적인 개폐장치에 널리 사용되고 있으며, 그 형태 및 모양을 달리하여 여러 분야에 다양하게 적용되고 있는 실정이다.Lock hinge of such a structure is simple, less fixed, easy to adjust the angle is widely used in the general opening and closing device, it is a situation that is applied to various fields by changing the shape and shape.

최근에 가장 수요가 많은 휴대폰, 노트북컴퓨터 등과 같은 소형 전자제품에 적용되는 힌지장치는 편측 록힌지, 양측 록힌지 등과 같은 종류가 주로 사용되고 있으며, 이러한 힌지장치는 회전캠과 고정캠의 대응구조를 이용하여 커버의 개폐를 용이하게 할 뿐 아니라, 외부 충격에도 개폐상태가 일정하게 유지되도록 구성되어 있다.Recently, the hinge devices applied to small electronic products such as mobile phones and notebook computers, which are most in demand, are mainly used as one-sided lock hinges and two-sided lock hinges. In addition to facilitating the opening and closing of the cover, it is configured to maintain a constant opening and closing state even in the external impact.

도 1에 도시된 바와 같이, 종래의 휴대폰 힌지구조는 플랜지(8)가 구비되어 있는 샤프트(7)가 고정캠(1), 회전캠(3), 스프링(4), 결합링(5)을 차례로 관통하여상기 고정캠(1)에 형성되어 있는 결합홈(2)상에 상기 샤프트(7)의 단부에 형성되어 있는 결합돌기(6)가 결합, 고정되어 있는 형태를 가지고 있거나, 샤프트에 결합부를 형성하여 플랜지부를 별도로 결합하는 방법을 사용하여 왔다.As shown in FIG. 1, in the conventional mobile phone hinge structure, a shaft 7 having a flange 8 includes a fixed cam 1, a rotary cam 3, a spring 4, and a coupling ring 5. In order to penetrate one by one, the engaging projection 6 formed at the end of the shaft 7 on the coupling groove 2 formed in the fixed cam 1 has a shape in which it is engaged and fixed, or is coupled to the shaft. A method of forming parts and joining flange parts separately has been used.

그러나 상기와 같은 힌지구조는 조립 부품수가 많고, 그 결합구조가 복잡하여 작업공정이 늘어나는 것은 물론이고 조립성이 저하되는 하나의 요인이 되었으며, 그로 인해 제품단가가 상승되는 결과를 초래하므로 시간적·경제적으로도 비효율적이었다.However, the hinge structure as described above has a large number of assembly parts, and its coupling structure is complicated, which leads to an increase in the work process and a decrease in assemblability. It was also inefficient.
