▶ 요약
1. JIN FENG Electronics: Patent 1- 种柔性屏(flexible display)应用的同轴190度外折 (190 ° coaxial outward folded) 转动机构 (rotation structure)
1) 아웃 폴딩 구조 자체를 특허로 출원함: 기어를 사용한 190o 아웃폴딩
2) 스프링을 이용한 damping 구조를 적용해 플렉시블 디스플레이 벤딩 부문의 손상 방지
3) 이 특허의 문제점은 벤딩을 구현하기 위한 기계적 구조의 크기를 줄이는 한계로 Folding 시 상하면 사이에 큰 공간이 생김
4) 특허 가치가 크지 않음
2. Hangzhou Amphenol Phoenix : 2018 (Patent 1, Utility 3) - 특허 一种内折(in-folding) 柔性屏 (flexible display)移动终端 (mobile terminal)铰链(hinge)及内折柔性屏移动终端
1) 인 폴딩 구조에서 접었을 때 디스플레이 벤딩 부분을 수용할 공간을 제공하는 힌지 구조 제안
2) 펼쳤을 떄 디스플레이의 torsion spring의 인장력을 이용해 제2지지대를 평행하게 받치는 힌지 구조 제안
3) 제1 지지대 말단부에 short arm을 설치해 펼쳤을 때 제2 지지대가 평행하게 지지 받도록 함
4) 3개의 비슷한 실용 신안 중 대표적인 하나를 선정해 분석함:内折(in-folding)柔性屏(flexible display)移动终端(mobile terminal)的铰链(hinge)及内折柔性屏移动终端
(1) 인 폴딩 구조의 디스플레이 벤딩부 하단에서 디스플레이의 지지대가 상하로 움직일 수 있게함
(2) 접힐 때 지지대가 빠르게 접히게 해 필요한 디스플레이의 수용 공간을 신속히 확보하고 디스플레이의 deformation을 방지함
3. Hangzhou Amphenol Phoenix : 2017 (Design 1, Utility 6)
1) 6개의 실용신안 중 5개가 관련 특허임. 관련 5개 중 두개는 2018년 실용신안의 old version임
2) 5개 중 2개는 chain형태의 힌지로 과거 특허에서 흔히 보는 유형임
3) 마지막 1개는 큰 스크린을 제공할 목적으로 휴대성이 떨어짐. 따라서 우리의 타켓과 차이가 큼
1. JIN FENG Electronics
1) Patent :一种柔性屏(flexible display)应用的同轴190度外折 (190 ° coaxial outward folded) 转动机构 (rotation structure)
2) Pub. Num. : CN108999882, App. Date: 2018.10, Type: invention
3) Solving the problem: [corresponding]
(1) 0-190° outward folding
(2) Protect the display from deformation during the process of bending (folding)
(3) Precisely control the flexible bending (folding）
4) Solution:
(1) Using gear coaxial rotation for purity mechanical bending
(2) Using damping structure with multi-unit springs and spring slide rail offset structure
(3) Limit structure(限位结构) with connecting fixed block (12连接固定块)
5) Opinion: Too much space in the hinge bending part → We may make the hinge components small enough to reduce the space in the bending part, but still we could not eliminate the space
2. Hangzhou Amphenol Phoenix 1
1) Patent :一种内折(in-folding) 柔性屏 (flexible display)移动终端 (mobile terminal)铰链(hinge)及内折柔性屏移动终端
2) Pub. Num. : CN108173995, App. Date: 2018.1, Type: invention
3) Solving problem:
(1) Providing space for flexible display’s bending part when folded;
(2) Providing flat supporting for flexible display when unfolded
(3) No exposure of hinge part
(4) User-friendly
3. Hangzhou Amphenol Phoenix 2
1) Patent : 内折(in-folding)柔性屏(flexible display)移动终端(mobile terminal)的铰链(hinge)及内折柔性屏移动终端
2) Pub. Num. : CN207977993, App. Date: 2018.2, Pub. Date: 2018.10, Type: utility model
3) Solving problem:
(1) This hinge could reduce the stretching and compressing of the flexible display when folding or unfolding
(2) Rising-lowing plate(升降板)：providing space for flexible display when folded
(3) Specifically, rising-lowing plate descends ¾ of the total height when 180°à90° and descends the rest ¼ when 90°à0°. Thus, rising-lowing plate descends quickly at the beginning and forms the space for the flexible display (protect the flexible display)
4. Hangzhou Amphenol Phoenix 2017 sorting
1) There are 7 patents applied in 2017 (0 invention, 1 design, 6 utility model)
2) Among the 6 utility model patents, one was ruled out for not being applied for flexible display
3) Among the rest 5 patents, one (CN 207603692 from different author) also related to rising-lowing plate, but no better than CN207977993 (the front page patent) [also one similar patent from the same author CN 207460248]
4) Among the rest 3 patents, one (CN 207782858) has the similar structure with other patents.
5) Among the rest 2 patents, one (CN 207200775) has a book-type shape which is far from portability and is inaesthetic . Similar hinge structure with no.4.
6) The last patent (CN 207543155) [printed] has the same author as CN108173995.
