Abstract
A two-axis hinge device in which a first housing and a second housing that are joined by a hinge can be opened into varied states and the degree of freedom of the rotation angle of the first housing and the second housing when they are rotated is increased. Two open/close shafts (10, 11) are placed to join the first housing and the second housing in an openable/closable manner. A torque unit is formed such that fixed cams (16, 18) and rotating cams (15, 19) inserted in the open/close shafts (10, 11) are in contact with each other at contact cam surfaces to generate sliding friction torque or click torque when the open/close shafts (10, 11) are rotated. A hinge is formed such that two or more torque units are independently provided at both ends of a spring (17) inserted in one of the open/close shafts (10 or 11). The rotating cams (15, 19) are formed as one joined part and assembled to both open/close shafts (10, 11). Thus a two-axis hinge device where two single axis hinge are integrated in a parallelly arranged manner is formed.

The present invention relates to a two-axis hinge device.
背景技術 Background art
[0002] 一般に、 2つ折り型の携帯電話には、キーボードが設置された第 1筐体と、画像を 写す液晶モニター (LCD)が組み込まれた第 2筐体との間を 1軸のヒンジ装置で結合 することにより、 1軸ヒンジの軸を中心として第 2筐体 (LCD側)を回転させる開閉動作 を行うように構成したものがある。 [0002] In general, a two-fold type mobile phone has a single-axis hinge device between a first housing in which a keyboard is installed and a second housing in which a liquid crystal monitor (LCD) for capturing images is incorporated. Some are configured to open and close by rotating the second housing (LCD side) around the axis of the 1-axis hinge.
[0003] さらに、 2つ折り型の携帯電話には、第 1筐体と第 2筐体間との間を 2本の軸を交差 させた構造の 2軸ヒンジで結合することにより、第 1筐体と第 2筐体との間で、一方の 1 軸ヒンジにより開閉動作可能に構成し、これに直交する他方の 1軸ヒンジで液晶モ- ターを設けた第 2筐体の回転動作を可能に構成したものがある。 [0003] Furthermore, the two-fold type mobile phone is connected to the first casing by connecting the first casing and the second casing with a two-axis hinge having a structure in which two axes intersect. It can be opened and closed with one uniaxial hinge between the body and the second housing, and the second housing with the liquid crystal motor can be rotated with the other uniaxial hinge perpendicular to it. There is something configured.
[0004] また、図 17に示す如き 2つ折り型の携帯電話で、第 1筐体と第 2筐体とを開閉動作 可能に連結する 1軸ヒンジでは、シャフト 100に圧縮コイルばね 101を揷通し、圧縮コ ィルばね 101の両端部にそれぞれ回転カム 103と固定カム 104と力も構成されたトル ク発生部を 2箇所設置して構成することにより、高耐久性、小型化、軽量化を図ったも のが提案されている (例えば、特許文献 1参照。 ) o [0004] In addition, in a two-fold type mobile phone as shown in FIG. 17, the first casing and the second casing are connected so as to be capable of opening and closing. In the single-axis hinge, the compression coil spring 101 is passed through the shaft 100. The torque generator 101 has two torque generators, each of which has a rotating cam 103, a fixed cam 104, and a force, on both ends of the compression coil spring 101 to achieve high durability, downsizing, and weight reduction.

[0005] 前述のような 2つ折り型の携帯電話では、第 1筐体と第 2筐体との間に、単一の 1軸 ヒンジを組み付けて開閉動作を行わせる構造であるため、一 1軸ヒンジを中心に開閉 動作をさせたときに第 1筐体と第 2筐体との一部が衝突することを避けるため、回転角 度を制限する回転ストッパー機構を設置する。回転ストッパー機構は、いわゆる筐体 ストッパー機構と称され、ヒンジを設置した第 1筐体と第 2筐体とに突き当てのための 突起を設け、突起が当接することで、第 1筐体と第 2筐体との開閉角度を制限するよう に構成している。
[0006] このため、 2つ折り型の携帯電話では筐体ストッパー機構により、第 1筐体に対して 第 2筐体を 180° 以下の回転角度で開いた状態に設定して使用するのが普通であ る。 [0005] Since the two-fold mobile phone as described above has a structure in which a single uniaxial hinge is assembled between the first housing and the second housing to perform opening and closing operations, A rotation stopper mechanism that limits the rotation angle is installed to prevent the first and second cases from colliding with each other when they are opened and closed around the shaft hinge. The rotation stopper mechanism is referred to as a so-called housing stopper mechanism, and is provided with protrusions for abutment on the first housing and the second housing on which the hinges are installed. It is configured to limit the opening / closing angle with the second housing. [0006] For this reason, it is common for a two-fold type mobile phone to be used with the case stopper mechanism set to open the second case at a rotation angle of 180 ° or less with respect to the first case. It is.
[0007] このような 2つ折り型の携帯電話においては、第 1筐体に対して第 2筐体を略 360° に近い角度範囲で回転可能にし、又は第 1筐体と第 2筐体とを 180° 回転して開い た状態で段差がない水平となるようにする等の、開状態の多様化、回転動作の自由 度の拡大に対する強 、要求がある。 [0007] In such a two-fold mobile phone, the second housing can be rotated in an angle range close to approximately 360 ° relative to the first housing, or the first housing and the second housing There is a strong demand for diversification of the open state and expansion of the degree of freedom of rotational movement, such as turning it 180 ° and making it level with no step in the open state.

[0060] 2軸型ヒンジ装置 1の組立に当たり、まず開閉軸 10, 11には、その第 1のスプライン 形状部 11— 1と丸軸部 11— 2との境界部分にそれぞれロックブロック 12を挿通し、さ らに丸軸部 11— 2の部分に、共通部品であるボディストッパー 13を挿通し、第 2のス プライン形状部 11 3の部分に各トルクプレート 14を挿通する。 [0060] When assembling the biaxial hinge device 1, first, the lock blocks 12 are respectively inserted into the opening / closing shafts 10 and 11 at the boundary between the first spline-shaped portion 11-1 and the round shaft portion 11-2. Further, the body stopper 13 which is a common part is inserted into the portion of the round shaft portion 11-2, and each torque plate 14 is inserted into the portion of the second spline shape portion 113.
[0061] 次に、各開閉軸 10, 11の第 2のスプライン形状部 11 3部分には、他の部品よりも 外形が大きい共通部品である第 1回転カム 15を挿通して力も第 1固定カム 16をそれ ぞれ揷通し、第 1回転カム 15の凸凹溝カム面に固定カム 16の凸凹溝カム面を当接さ
せるよう糸且立てる。 [0061] Next, a first rotating cam 15, which is a common part having a larger outer shape than the other parts, is inserted into the second spline-shaped part 11 3 portion of each of the opening and closing shafts 10, 11, and the force is also fixed to the first. Each cam 16 is threaded, and the concave and convex groove cam surface of the fixed cam 16 is brought into contact with the concave and convex groove cam surface of the first rotating cam 15. Thread it up to make it stand.
[0062] 次に、各開閉軸 10, 11の第 2のスプライン形状部 11 3部分には、圧縮コイルば ね 17を、固定カム 16の溝付カム面の裏平面側に揷通する。さらに各開閉軸 10, 11 の第 2のスプライン形状部 11 - 3部分には、 2箇所目のトルク発生部として圧縮コイル ばね 17に続いて第 2固定カム 18を挿通し、共通部品である第 2回転カム 19を挿通し てカム面を第 2固定カム 18のカム面に当接させるように組立て、最後に固定部 11— 4の部分をリベッテングリング 20を貫通した状態で固定することにより図 2に示すよう な 2軸型ヒンジ装置 1を完成する。 Next, a compression coil spring 17 is passed through the second spline-shaped portion 113 portion of each of the open / close shafts 10 and 11 through the back plane side of the grooved cam surface of the fixed cam 16. Further, a second fixed cam 18 is inserted into the second spline-shaped portion 11-3 portion of each of the opening and closing shafts 10, 11 as a second torque generating portion, followed by the compression coil spring 17, and the second component is a common part.

[0063] リベッテングリング 20を固定部 11— 4に固定するときには、圧縮コイルばね 17を圧 縮させるように荷重を掛けつつ各開閉軸 10, 11の固定部 11— 4までリベッテンダリン グ 20を圧入後、軸端部をカシメ加工により固定する。 [0063] When the rivet ring 20 is fixed to the fixing part 11-4, the riveting ring 20 is press-fitted to the fixing part 11-4 of each of the opening and closing shafts 10, 11 while applying a load so as to compress the compression coil spring 17. After that, the shaft end is fixed by caulking.
[0064] なお、図 1および図 2に示す 2軸型ヒンジ装置 1では、開閉軸 10と、開閉軸 11とに組 み付ける各部品を基本的に同一な形状、動きをなすもので構成している。しかし本発 明の 2軸型ヒンジ装置は、ヒンジ仕様により、開閉軸 10と開閉軸 11とでヒンジを構成 する部品の形状、構成数、動きが違うように構成しても良い。 [0064] In the biaxial hinge device 1 shown in Figs. 1 and 2, the components assembled to the opening / closing shaft 10 and the opening / closing shaft 11 are basically configured to have the same shape and movement. ing. However, the two-shaft hinge device of the present invention may be configured such that the shape, number of components, and movement of the parts constituting the hinge are different between the opening / closing shaft 10 and the opening / closing shaft 11 depending on the hinge specification.
[0065] 図 2に示した 2軸型ヒンジ装置 1では、トルクユニットの第 1回転カム 15、第 1固定力 ム 16、第 2固定カム 18,第 2回転カム 19の状態力 凸凹溝がお互いに不整合である 摺動状態で圧接されている。 2軸型ヒンジ装置 1では、この摺動状態において、圧縮 コイルばね 17が軸方向に最も圧縮され、大きな反発力を発揮する状態となっている。 [0065] In the two-shaft hinge device 1 shown in Fig. 2, the state force of the first rotating cam 15, the first fixing force drum 16, the second fixing cam 18, and the second rotating cam 19 of the torque unit is different from each other. It is press-contacted in a sliding state. In the biaxial hinge device 1, in this sliding state, the compression coil spring 17 is compressed most in the axial direction and exhibits a large repulsive force.
[0066] また、 2軸型ヒンジ装置 1では、クリックトルクは、第 1回転カム 15と第 1固定カム 16と の間、第 2回転カム 19と第 2固定カム 18との間の、凸凹溝付カム面が整合当接する 4 箇所のトルクユニットで発生する。 [0066] In the biaxial hinge device 1, the click torque is an uneven groove between the first rotating cam 15 and the first fixed cam 16, and between the second rotating cam 19 and the second fixed cam 18. Generated at the four torque units where the attached cam surface is aligned and abutting.
[0067] また摺動トルクは、ストッパー用ロックブロック 12とストッパー用ボディーストッパー 13 との間、ストッパー用ボディーストッパー 13とトルクプレート 14との間、トルクプレート 1 4と第 1回転カム 15との間、及び第 2回転カム 19とリベッティングリング 20との間の、 合計 8箇所で発生する。なお、固定および回転カムが不整合当接の場合は、摺動ト ルクを発生する。 [0067] The sliding torque is measured between the stopper lock block 12 and the stopper body stopper 13, between the stopper body stopper 13 and the torque plate 14, and between the torque plate 14 and the first rotating cam 15. And a total of 8 locations between the second rotating cam 19 and the riveting ring 20. If the fixed and rotating cams are in misaligned contact, a sliding torque is generated.
[0068] 図 2に示した 2軸型ヒンジ装置 1における回転角度を制限する回転ストッパーとて、
図 4に示すように、回転軸を中心として 40° の範囲に設けられたストッパー用ロックブ ロックの突起 12— 3が、回転軸を中心として 130° の範囲に設けられたストッパー用 ボディーストッパー 13の平坦部 13— 3に摺接可能とし、 140° の範囲に設けられた ストッパー用ロックブロックの平坦部 12— 6が、 50° の範囲に設けられたストッパー用 ボディーストッパーの突起 13— 4に摺接可能として構成される。 [0068] As a rotation stopper for limiting the rotation angle in the biaxial hinge device 1 shown in FIG. As shown in Fig. 4, the protrusion 12-3 of the stopper lock block provided in the range of 40 ° around the rotation axis is the same as that of the body stopper 13 for the stopper provided in the range of 130 ° around the rotation axis. The flat part 12-6 of the stopper lock block provided in the range of 140 ° is slidable on the protrusion 13-4 of the body stopper for the stopper provided in the range of 50 °. It is configured as accessible.
[0069] このように構成された両部品の回転可能域は、突起 12— 3および突起 13— 4が回 転軸を中心として、それぞれ平坦部 13— 3および平坦部 12— 6の角度域内で回転し て、平坦部 13- 3または平坦部 12- 6の両端に位置する突起 13— 4および突起 12 3に突き当たるまでの角度として設定される。 [0069] The rotation range of both parts configured in this way is within the angular range of the flat portion 13-3 and the flat portion 12-6, with the protrusion 12-3 and the protrusion 13-4 centered on the rotation axis, respectively. It is set as an angle until it rotates and abuts against the projection 13-4 and the projection 123 located at both ends of the flat portion 13-3 or the flat portion 12-6.
[0070] この例では、平坦部 13-3 (130° ) 突起 12- 3 (40° ) = 90° および平坦部 12- 6 (140° )—突起 13-4 (50° ) = 90° が回転可能域である。図 4Dの例では、突起 13— 4と平坦部 13— 3の角度設定が上下の回転ストッパーで同じであり、かつ図 4C で示されるストッパー用ロックブロック 12を 2個使用すると、上下の各 1軸ヒンジの回転 可能域は共に 90° である。この例の場合、 2軸型ヒンジ装置 1の最大回転角度は、 9 0° の 2倍の 180° となる。 [0070] In this example, flat 13-3 (130 °) protrusion 12-3 (40 °) = 90 ° and flat 12-6 (140 °) —protrusion 13-4 (50 °) = 90 ° It is a rotatable range. In the example of Fig. 4D, the angle settings of the protrusion 13-4 and the flat portion 13-3 are the same for the upper and lower rotation stoppers, and if two stopper lock blocks 12 shown in Fig. 4C are used, each of the upper and lower 1 The rotatable range of the shaft hinge is 90 °. In this example, the maximum rotation angle of the biaxial hinge device 1 is 180 °, which is twice 90 °.
[0071] なお、回転ストッパーの設定は、突起および平坦部の数や角度あるいは軸径方向 の円周に沿って並列に設置する方法、ストッパー用ロックブロック 12及びストッパー 用ボディーストッパー 13について上下の各開閉軸 10, 11で異なる条件設定の部品 を採用する方法を組み合わせることが可能であり、 360° の回転範囲で更に多様な 組み合わせが可能である。また、ストッパー用ロックブロック 12及びストッパー用ボデ イーストツバ一 13の材料には、強度と耐磨耗に優れた金属、榭脂等を利用できる。ま た突起は、プレスおよび榭脂成形で形成する他に、ピンの埋設により構成しても良い [0071] It should be noted that the rotation stoppers are set according to the number and angle of protrusions and flat portions, the method of installing them in parallel along the circumference in the axial direction, the lock block 12 for stoppers, and the body stopper 13 for stoppers. It is possible to combine methods that use parts with different condition settings for the open / close shafts 10 and 11, and a wider variety of combinations are possible within a 360 ° rotation range. Further, the material of the stopper lock block 12 and the stopper body 13 can be made of metal, grease, etc. having excellent strength and wear resistance. The protrusions may be formed by embedding pins in addition to being formed by pressing and resin molding.
