Abstract

A spring for elastic sliding in a portable wireless terminal is provided to assure reliability on elastic operation of a sub body as well as to prolong a life of the portable wireless terminal because the spring has a better restoration force, a better elastic force maintaining function and a smooth operation feature. A spring for elastic sliding in a portable wireless terminal comprises elastic support rods(11,12,13), connection rods(14,15), elastic spaces(20,20'), a fixing ring(16) and assistant elastic spaces. The elastic support rods(11,12,13) are formed by bending round bar made of shape memory alloy. The connection rods(14,15) connect an upper end of the first elastic support rod(11) and the second elastic support rod(12) to a lower end of the second elastic support rod(12) and the third support rod(13) such that the elastic spaces(20,20') can be formed. The fixing ring(16) is formed at an end of the first and the third elastic support rod(11,13). The connecting rods(14,15) connect both ends of the second elastic support rod(12) to the first and the third elastic support rod(11,13) such that the assistant elastic spaces can be formed over the connecting rods(14,15).

본 발명은 휴대 무선단말기의 탄력 슬라이딩용 스프링에 관한 것으로서 이를 좀더 구체적으로 설명하자면 서브바디의 슬라이딩 작동에 대한 내구성이 우수하고, 또 그 작동도 원할 하게 되는 스프링를 얻을 수 있도록 한 것이다.The present invention relates to a spring for the elastic sliding of the portable wireless terminal to be described in more detail to be able to obtain a spring that is excellent in the durability of the sliding operation of the sub-body, and also the operation is desired.

일반적으로 휴대 무선단말기라 함은 휴대전화를 말하는 것으로, 현재에는 과거의 플립형, 폴드형과 다른 방식의 휴대전화 즉, 버튼 등이 장치된 메인바디 상부에 디스플레이창을 가진 서브바디가 휴대전화의 길이방향으로 탄력 슬라이딩 개폐되도록 한 휴대전화로 바뀌어 가고 있으며, 위 휴대전화는 과거의 휴대전화에 비해 개폐조작이 용이하여 범용화 되고 있다.In general, a portable wireless terminal refers to a mobile phone. At present, the mobile phone is a sub-body having a display window on the main body where buttons, etc., are flip-folded and fold-type. It is changing to a mobile phone that is elastically sliding opening and closing in the direction, and the above mobile phone has been generalized because it is easier to open and close than the mobile phone of the past.

그러나 현재까지 출시되어 있는 대부분의 슬라이딩 개폐형 휴대전화는 일정시간(약1년 정도)이 지나면 서브바디의 탄력 슬라이딩 작동이 처음에 비해 현저하게 저하되었을 뿐만 아니라 그 작동도 원할 하지 못한 문제점이 있었고, 이는 휴대전화의 수명을 단축하는 주요 원인이 되어왔는데, 그 이유는 서브바디를 탄력 슬라이딩 작동케 하는 스프링을, 일정한 시간 동안 반복작동하면 탄력(텐션)이 급격하게 떨어지는 토션스프링 혹은 인장스프링으로 하였기 때문에 시간에 대한 내구성이 극히 저조하기 때문인 것이다. However, most of the sliding open and closed mobile phones that have been released to date, after a certain period of time (about a year), the elastic sliding operation of the sub-body not only significantly decreased compared to the first time, but also did not want the operation. It has been a major cause of shortening the lifespan of mobile phones, because the springs that make the subbody resilient sliding act as a torsion spring or a tension spring that drops sharply when tension is repeated for a certain time. This is because the durability against the extremely low.

위 토션스프링 혹은 인장스프링은 중앙 또는 전체를 코일형으로 권취하여 그 코일의 텐션에 의해 탄력이 발생하는 것이어서 수회에 걸쳐 반복작동하면 처음의 탄력을 유지할 수 없는 결점이 있고, 또 그로 인하여 탄력 작동도 원할 하지 못한 문제점이 있는 것으로 인식 되어져있다. The torsion spring or tension spring is coiled in the center or the whole, and the elasticity is generated by the tension of the coil. Therefore, if it is repeatedly operated several times, there is a defect that the initial elasticity cannot be maintained. It is recognized that there is an undesired problem.

본 발명은 위와 같이 현재 범용화가 되고 있는 슬라이딩 개폐형 휴대 무선단말기의 슬라이딩용 스프링에서 나타나는 문제점을 해결하기 위함에 그 기술적인 과제를 두고 발명한 것으로 특히, 반복적인 작동에도 불구하고 탄력이 항상 일정하게 유지되고, 또 그 작동도 원할하게 되는 휴대 무선단말기의 슬라이딩용 스프링를 제공할 수 있도록 한 것이다.The present invention has been invented with the technical problem to solve the problems appearing in the sliding spring of the sliding open / closed portable wireless terminal which is currently being widely used as above, in particular, the elasticity is always kept constant despite repeated operations. In addition, it is possible to provide a sliding spring of the portable wireless terminal that the operation is desired.

이를 첨부되는 도면과 함께 더욱더 상세히 설명하면 다음과 같다.This will be described in more detail together with the accompanying drawings as follows.

휴대 무선단말기(이하"휴대전화"라 함)의 길이방향으로 슬라이딩 되는 서브바디(60)용 서브플레이트(61)와 상기 서브플레이트(61)의 슬라이딩 작동을 안내하는 메인바디(50)용 고정플레이트(51) 사이에 구비되어 일측 끝단은 서브플레이트(61)에 고정되고 타측 끝단은 고정플레이트(51) 고정됨으로써 서브플레이트(60)를 탄력적으로 슬라이딩 작동케 하는 스프링(1)을, 형상기억합금(니켈 + 티타늄)의 소재(환봉)로 절곡 형성하여 제1,2,3탄력지지대(11)(12)(13)가 형성되도록 하되, 상 기 제1탄력지지대(11)와 제2탄력지지대(12) 상단 및 제2탄력지지대(12)와 제3탄력지지대(13) 하단을 각각의 연결대(14)(15)로 연결하여 스프링(1)이 복수 개의 탄력공간(20)(20')이 형성되는 "

It is to be formed in the shape so that the secondary elastic space (21, 21 ') is formed on the connecting table (14, 15).

이와 같이 된 본 발명은 휴대전화의 서브바디(60)를 탄력 슬라이딩케 하는 스프링(1)을 형상기억합금으로 제조함으로써 복원력이 우수함은 물론 장 시간 동안의 반복적인 작동(100만회 이상)에도 탄력이 저하되는 현상을 배제할 수 있게 되며, 또 탄력공간(20)(20')이 복수 개 형성되기 때문에 복원력 및 탄력이 더욱 탁월할 뿐만 아니라 그 작동도 원할하게 되고, 또 스프링(1)을 절곡 형성하므로 그 생산성이 향상되며,The present invention as described above is produced by the shape memory alloy of the spring (1) to make the elastic sliding of the sub-body 60 of the mobile phone is excellent in resilience and resilient even in repetitive operation (more than 1 million times) for a long time The deterioration phenomenon can be eliminated, and since the plurality of elastic spaces 20 and 20 'are formed, not only the restoring force and elasticity are more excellent, but also the operation thereof is desired, and the spring 1 is bent. To increase productivity,

또한 스프링(1)의 제2탄력지지대(12)를 둥글게 형성하면서 그 양단을 제1,3탄력지지대(11)(13)와 연결하면 탄력효율이 뛰어나게 되고, 또 이 탄력효율은 그 양측의 연결대 상부에 형성되는 보조탄력공간(21)(21')으로부터 조력 받게 되어 더욱더 탄력효율이 높아지게 된다. In addition, when the second elastic support 12 of the spring (1) is rounded and connected to both ends of the first and third elastic support (11) (13), the elastic efficiency is excellent, and this elastic efficiency is the connection table on both sides It is assisted by the auxiliary elastic spaces 21 and 21 'formed on the upper side, and the elasticity efficiency is further increased.

그리고 스프링(1)의 양측 고정링(16)은 각각 서브플레이트(61) 및 고정프레이트(51)의 측부 일정위치에 회동가능케 고정되는 것인데, 그 고정방식은 서브, 고정플레이트(51)(61)의 관통공에 형성 또는 삽입되는 고정축에 이탈되지 않도록 고정되며, 상기의 고정방식은 통상적으로 실시되고 있는 방식인 것이다.And both sides of the fixing ring 16 of the spring (1) is rotatably fixed to the side position of the sub plate 61 and the fixing plate 51, respectively, the fixing method is the sub, fixed plate (51, 61) It is fixed so as not to be separated from the fixed shaft formed or inserted into the through-hole of the, the fixing method is a method that is conventionally carried out.

따라서 본 발명은 상기한 바와 같이 복원력 및 탄력 유지성이 우수하면서 작동도 원할 한 스프링(1)을 얻을 수 있게 되어 휴대전화의 수명을 보다 연장시 킬 수 있음과 아울러 서브바디(60) 탄력 작동에 대한 신뢰성을 보장받을 수 있는 효과가 있으며, 여기서 우수한 복원력과 탄력 유지성이라 함은 스프링(1)의 내구성 및 내마모성이 탁월하다는 것을 말하는 것이고, 나아가 스프링(1)의 생산성이 향상되어 그 생산원가를 줄일 수 있음은 물론 그로 인하여 휴대전화를 보다 저렴한 가격으로 소지바들에게 제공할 수 있게 되는 효과도 있는 것이다. Therefore, the present invention can obtain a spring (1) as long as it is excellent in resilience and elasticity retention and operation as described above can extend the life of the mobile phone more and also for the sub-body (60) elastic operation Reliability can be guaranteed, and excellent resilience and elasticity retention means that the durability and abrasion resistance of the spring (1) is excellent, and furthermore, the productivity of the spring (1) can be improved to reduce the production cost thereof. Of course, there is also an effect that can be provided to the mobile phone at a lower price due to the mobile phone.
