Description

この発明は、例えば２つの筐体が見開き式に開閉可能に連結された携帯電話機やＰＤＡ等の携帯端末に用いられるようなヒンジ機構及び携帯端末に関する。   The present invention relates to a hinge mechanism and a mobile terminal used for a mobile terminal such as a mobile phone or a PDA in which, for example, two casings are connected so as to be openable and closable.

従来、携帯端末としては、携帯電話機やＰＤＡ、ノート型パソコン等、様々な端末が提供されており、これらの携帯端末として、表示部を有する蓋部とキー操作部を有する本体部とが見開き式に折りたたみ可能に連結された所謂クラムシェルタイプのものが提供されている。   Conventionally, various terminals such as a mobile phone, a PDA, and a notebook personal computer have been provided as portable terminals. As these portable terminals, a lid portion having a display portion and a main body portion having a key operation portion are spread. A so-called clamshell type is provided which is foldably connected to the other.

このように携帯端末に用いられるクラムシェルタイプの連結部として、連結された２つの筐体がギアによって同時に反対方向へ回動するヒンジ機構が提案されている（特許文献１参照）。
しかし、このようにギアを使用する構造は、ギアの歯飛び等によって故障する可能性があるという問題があった。特に、携帯端末の小型化によりギアが小型化すると、この問題が顕著に現れる可能性があった。 As a clamshell type connecting part used for a mobile terminal in this manner, a hinge mechanism has been proposed in which two connected cases are simultaneously rotated in opposite directions by a gear (see Patent Document 1).
However, such a structure using a gear has a problem that it may break down due to gear tooth skipping or the like. In particular, when the gear is miniaturized due to the miniaturization of the portable terminal, this problem may appear remarkably.

また、他の種類の連結部として、一方のヒンジ体に紐等の連動帯を接続し、２軸間を通過させた後にもう一方のヒンジ体に接続して、２軸ヒンジを逆回転で連動させる機構が提案されている（特許文献２参照）。
しかし、連動帯には伸び縮みするという問題が考えられ、また、すべりが発生する問題も考えられた。 In addition, as another type of connecting part, an interlocking band such as a string is connected to one hinge body, and after passing between two axes, it is connected to the other hinge body, and the two-axis hinge is interlocked by reverse rotation. A mechanism has been proposed (see Patent Document 2).
However, there was a problem of expansion and contraction in the interlocking zone, and a problem of slippage was also considered.

このように、２軸のヒンジで連動して逆回転する構成について、充分な機構は提案されていなかった。   As described above, no sufficient mechanism has been proposed for a structure that rotates in reverse by interlocking with a biaxial hinge.

The link arm 87 is preferably formed of a material that is highly rigid and does not deform, but can also be formed of a metal member that is elastically deformed to a slight degree.

以上に説明した各構成要素を組み合わせると、図３での左側から見た斜視図である図６、及び図３での右側から見た斜視図である図７に示すように、ヒンジユニット３０が完成する。完成したヒンジユニット３０は、２つの回動範囲規制軸３１が軸装着板９５に固定されており、該回動範囲規制軸３１を軸に、回動アーム７０ａと回転体８１ａとが一体に回転し、またこの逆方向へ回動アーム７０ｂと回転体８１ｂとが一体に回転する。この回転に際しては、付勢部４０の付勢力と位置係止部５０の凹凸嵌合（係止突起５２と係止孔５７との嵌合）により、全閉位置と全開位置とでクリック感が得られる。なお、クリック感を得るための構成は、これに限らず、適宜の構成を採用することができる。   When the components described above are combined, as shown in FIG. 6 which is a perspective view seen from the left side in FIG. 3 and FIG. 7 which is a perspective view seen from the right side in FIG. Complete. The completed hinge unit 30 has two rotation range restriction shafts 31 fixed to the shaft mounting plate 95, and the rotation arm 70a and the rotating body 81a rotate integrally around the rotation range restriction shaft 31. In addition, the rotating arm 70b and the rotating body 81b rotate integrally in the opposite direction. At the time of this rotation, there is a click feeling between the fully closed position and the fully open position due to the urging force of the urging portion 40 and the concave / convex fitting of the position locking portion 50 (fitting between the locking protrusion 52 and the locking hole 57). can get. Note that the configuration for obtaining the click feeling is not limited to this, and an appropriate configuration can be adopted.

次に、ヒンジユニット３０の動作について、図８の左側面による説明図、図９の右側面による説明図と共に説明する。ここで、図８については、理解の容易のために軸装着板９５を透過して図示している。   Next, the operation of the hinge unit 30 will be described together with an explanatory diagram on the left side of FIG. 8 and an explanatory diagram on the right side of FIG. Here, FIG. 8 is shown through the shaft mounting plate 95 for easy understanding.

全開位置では、図８（Ａ）の左側面図に示すように、回動アーム７０ａ，７０ｂが外側へ真っ直ぐ伸びた状態で係止されている。

さらに、図９（Ａ）の右側面図に示すように、回動アーム７０ａ，７０ｂの各回動範囲規制突起７１は、回動範囲規制軸３１の回動範囲規制面３３の片面に当接している。
そして、図５に示した回動角度係止板５５（５５ａ，５５ｂ）の係止孔５７に、位置係止ワッシャ５１の係止突起５２の一方が嵌合した状態で、係止されている。
また、携帯電話機１は、図１０（Ａ）の右側面図に示すように、全開状態となる。 In the fully open position, as shown in the left side view of FIG. 8A, the rotating arms 70a and 70b are locked in a state of extending straight outward.
At this time, the rotating body 81a is locked in a state in which the pivot hole 84 is located on the opening / closing inner surface 3a side (the upper side in the drawing) when viewed from the rotating shaft 39a of the rotating body 81a. The rotating body 81b is locked in a state where the pivot hole 84 is located on the rotating shaft 39a side of the rotating body 81a when viewed from the rotating shaft 39b of the rotating body 81b.
Further, as shown in the right side view of FIG. 9A, each rotation range restriction projection 71 of the rotation arms 70 a and 70 b is in contact with one surface of the rotation range restriction surface 33 of the rotation range restriction shaft 31. Yes.
And it locks in the state which one of the latching protrusions 52 of the position latching washer 51 fitted in the latching hole 57 of the rotation angle latching plate 55 (55a, 55b) shown in FIG. .
In addition, the mobile phone 1 is fully opened as shown in the right side view of FIG.

利用者によって閉動作がなされると、図８（Ｂ）の左側面図に示すように、回動アーム７０ａ，７０ｂが対称に逆回転する。
このとき、回転体８１ａは、枢支孔８４が回転体８１ｂ側（図示右方）へ移動するように左側面視時計回りに回転し、回転体８１ｂは、枢支孔８４が開閉外面側（図示下方）へ移動するように左側面視反時計回りに回転する。
この状態で、リンクアーム８７は、回転軸３９ａ，３９ｂ間を通過する態様になる。 When the closing operation is performed by the user, as shown in the left side view of FIG. 8 (B), the rotating arms 70a and 70b rotate in a reverse direction symmetrically.
At this time, the rotator 81a rotates clockwise so that the pivot hole 84 moves to the rotator 81b side (the right side in the figure), and the rotator 81b has the pivot hole 84 on the opening / closing outer surface side ( It rotates counterclockwise as viewed from the left side so as to move downward (shown in the figure).
In this state, the link arm 87 is configured to pass between the rotary shafts 39a and 39b.

さらに、図９（Ｂ）の右側面図に示すように、回動アーム７０ａ，７０ｂの各回動範囲規制突起７１は、回動範囲規制軸３１の回動範囲規制面３３から離間した状態となる。
またこの閉動作に移行する際、利用者による閉方向の作用力が図５に示した付勢部４０の付勢力を超えた時点で、回動角度係止板５５（５５ａ，５５ｂ）の係止孔５７から、位置係止ワッシャ５１の前記係止突起５２が抜け出す。
そして、携帯電話機１は、図１０（Ｂ）の右側面図に示すように、開閉途中の状態となる。 Further, as shown in the right side view of FIG. 9B, the respective rotation range restricting projections 71 of the turning arms 70 a and 70 b are separated from the turning range restricting surface 33 of the turning range restricting shaft 31. .
Further, at the time of shifting to this closing operation, when the acting force in the closing direction by the user exceeds the urging force of the urging unit 40 shown in FIG. 5, the engagement of the rotation angle locking plate 55 (55a, 55b). The locking projection 52 of the position locking washer 51 comes out from the stop hole 57.
Then, as shown in the right side view of FIG. 10B, the mobile phone 1 is in the middle of opening and closing.

利用者によって全閉位置まで閉動作がなされると、図８（Ｃ）の左側面図に示すように、回動アーム７０ａ，７０ｂが軸装着板９５に対してそれぞれ直角で、かつ互いに対向する平行状態で係止される。   When the user performs the closing operation to the fully closed position, as shown in the left side view of FIG. 8C, the rotating arms 70a and 70b are perpendicular to the shaft mounting plate 95 and face each other. Locked in parallel.

このとき、回転体８１ａは、該回転体８１ａの回転軸３９ａから見て回転体８１ｂの回転軸３９ｂ側に枢支孔８４が位置する状態で係止されている。また、回転体８１ｂは、該回転体８１ｂの回転軸３９ｂから見て開閉外面側（図示下方）に枢支孔８４が位置する状態で係止されている。
さらに、図９（Ｃ）の右側面図に示すように、回動アーム７０ａ，７０ｂの各回動範囲規制突起７１は、回動範囲規制軸３１の回動範囲規制面３３のうち、前述の全開状態とは逆側の面に当接している。
そして、図５に示した回動角度係止板５５（５５ａ，５５ｂ）の係止孔５７に、位置係止ワッシャ５１の係止突起５２の他方が嵌合して係止される。この嵌合により、利用者は適度なクリック感を得ることができ、完全に閉じられたことを理解できる。
また、携帯電話機１は、図１０（Ｃ）の右側面図に示すように、全閉状態となる。 At this time, the rotating body 81a is locked in a state where the pivot hole 84 is located on the rotating shaft 39b side of the rotating body 81b when viewed from the rotating shaft 39a of the rotating body 81a. The rotating body 81b is locked in a state where the pivot hole 84 is located on the opening / closing outer surface side (lower side in the drawing) when viewed from the rotating shaft 39b of the rotating body 81b.
Further, as shown in the right side view of FIG. 9C, the rotation range restriction projections 71 of the rotation arms 70 a and 70 b are the above-described fully opened portions of the rotation range restriction surface 33 of the rotation range restriction shaft 31. It is in contact with the surface opposite to the state.
Then, the other of the locking projections 52 of the position locking washer 51 is fitted and locked in the locking hole 57 of the rotation angle locking plate 55 (55a, 55b) shown in FIG. By this fitting, the user can obtain an appropriate click feeling and can understand that it is completely closed.
Further, the mobile phone 1 is fully closed as shown in the right side view of FIG.

このように、前述した実施形態のヒンジユニット３０は、回転中心軸を互いに平行にして軸支された２つの回転体８１ａ，８１ｂを、該回転体８１ａ，８１ｂ同士を連動させるリンクアーム８７で連結し、該リンクアーム８７を、前記回転中心軸同士の間を通過する態様に構成したものである。   As described above, in the hinge unit 30 of the above-described embodiment, the two rotary bodies 81a and 81b that are pivotally supported with the rotation center axes being parallel to each other are connected by the link arm 87 that interlocks the rotary bodies 81a and 81b. The link arm 87 is configured to pass between the rotation center axes.

この構成によれば、２つの回転体８１ａ，８１ｂを一動作で互いに連動させることができ、同角度ずつ同時に逆回転させることができる。
そして、従来から数多く提供されているヒンジ機構のように、蓋部３と本体部８とを開いた状態でヒンジが突出するといったことがなく、図１に示したように全開状態で開閉内面３ａ、内面６ａ、及び開閉内面８ａが面一になると共に、図１１の背面側から見た斜視図に示すように背面側から連結部６が視認できず、また全閉状態では図２で手前から見るように連結端面３ｂ，８ｂ側に連結部６が視認できるものの、連結端面３ｂ，８ｂ及び背面６ｂが面一であるため図２で上から見るように背面側から見れば連結部６が視認できないため、美しい美観の携帯電話機１を提供することができる。 According to this configuration, the two rotating bodies 81a and 81b can be interlocked with each other in one operation, and can be simultaneously rotated in reverse at the same angle.
The hinge does not protrude when the lid 3 and the main body 8 are opened unlike the many hinge mechanisms conventionally provided, and the open / close inner surface 3a is fully opened as shown in FIG. The inner surface 6a and the open / close inner surface 8a are flush with each other, and the connecting portion 6 is not visible from the rear side as shown in the perspective view seen from the rear side in FIG. As can be seen, although the connecting portion 6 can be visually recognized on the connecting end surfaces 3b and 8b side, the connecting end surfaces 3b and 8b and the back surface 6b are flush with each other, so the connecting portion 6 is visible when viewed from the back side as viewed from above in FIG. Since this is not possible, the mobile phone 1 having a beautiful beauty can be provided.

また、前記前記リンクアーム８７は、一方の前記回転体８１ａ（または８１ｂ）の回転により押動された際に他方の前記回転体８１ｂ（または８１ａ）を押動して回転させる程度の金属部材で形成したため、２つの回転体を安定して連動させることができる。   The link arm 87 is a metal member that pushes and rotates the other rotating body 81b (or 81a) when the link arm 87 is pushed by the rotation of one rotating body 81a (or 81b). Since it formed, two rotary bodies can be linked stably.

そして、回動範囲規制軸３１には回動範囲規制面３３が設けられ、回動アーム７０には回動範囲規制突起７１が設けられているため、限界を超えて開くといったことを防止でき、開けすぎによるリンクアーム８７の破壊などの故障を防止できる。   Since the rotation range restriction shaft 31 is provided with the rotation range restriction surface 33 and the rotation arm 70 is provided with the rotation range restriction projection 71, it can be prevented from opening beyond the limit. Failure such as destruction of the link arm 87 due to excessive opening can be prevented.

また、回動範囲規制軸３１には回転体８１及び回動アーム７０が挿通され、該回動範囲規制軸３１の端部に軸装着板９５が位置されており、リンクアーム８７も軸装着板９５に近接する位置に設けられて全体が平面視略コ字型に構成されているため、ヒンジユニット３０の携帯電話機１への組み込み配置の自由度が高くなる。
すなわち、図１２（Ａ），（Ｂ）の他の実施形態の斜視図に示すように、連結部６を２箇所設けてその一方あるいは両方にヒンジユニット３０を設ける、あるいは、連結部６を一方の側面に設けるなど、適宜の構成とすることができる。この場合でも、全開状態で携帯電話機１の背面側から連結部６が視認できず、美しい美観を得ることができる。 Further, the rotary body 81 and the rotary arm 70 are inserted through the rotation range restriction shaft 31, the shaft mounting plate 95 is located at the end of the rotation range restriction shaft 31, and the link arm 87 is also a shaft mounting plate. 95 is provided in a position close to 95 and is configured in a substantially U shape in plan view, so that the degree of freedom of mounting the hinge unit 30 in the mobile phone 1 is increased.
That is, as shown in a perspective view of another embodiment of FIGS. 12A and 12B, two connecting portions 6 are provided, and one or both of them are provided with a hinge unit 30, or one of the connecting portions 6 is provided. It can be set as an appropriate structure, such as being provided on the side surface. Even in this case, the connecting portion 6 cannot be visually recognized from the back side of the mobile phone 1 in the fully opened state, and a beautiful beauty can be obtained.

また、従来のギア式のヒンジ機構のようにギアの歯が欠けるといったことがないため、このようなギア式のヒンジ機構よりも軸間距離（回転軸３９ａ，３９ｂ間の距離）を短くしてヒンジユニット３０を小型化することができ、かつ高い耐久性を得ることができる。また逆に、軸間距離を必要なだけ拡張して連結部６のように外観カバーを設けることもできる。
そして、従来の連結体によるヒンジ機構のように連結体が伸びるといったこともないため、高い耐久性を得ることができる。 Further, since the gear teeth are not chipped unlike the conventional gear type hinge mechanism, the distance between the shafts (distance between the rotating shafts 39a and 39b) is made shorter than that of the gear type hinge mechanism. The hinge unit 30 can be reduced in size and high durability can be obtained. Conversely, the outer cover can be provided like the connecting portion 6 by extending the distance between the shafts as necessary.
And since a connection body does not extend like the hinge mechanism by the conventional connection body, high durability can be acquired.

また、リンク機構部８０に回転体８１とリンクアーム８７が採用されているため、蓋部３と本体部８との開閉動作のバラツキを解消でき、かつ滑りなどの伝導ロスを生じさせないことができる。   In addition, since the rotating body 81 and the link arm 87 are employed in the link mechanism portion 80, the variation in the opening / closing operation between the lid portion 3 and the main body portion 8 can be eliminated, and conduction loss such as slipping can be prevented. .

また、前述した実施態様の携帯電話機１は、前記ヒンジユニット３０を備えたものであるから、ヒンジユニット３０の回転体８１ａ，８１ｂが連動して互いに逆回転することで、蓋部３と本体部８とが連結部６に対して同量ずつ開閉する携帯電話機１を提供することができる。   Moreover, since the mobile phone 1 according to the above-described embodiment includes the hinge unit 30, the lid 3 and the main body can be obtained by rotating the rotating bodies 81a and 81b of the hinge unit 30 in reverse to each other. The mobile phone 1 that opens and closes the connecting portion 6 by the same amount can be provided.

なお、回動アーム７０の回動範囲を規制する構成は、上述した実施形態に限らず、例えば、回動アーム７０の軸挿通孔７３と回動範囲規制突起７１との位置関係を図３における左右逆に構成し、これによって回動範囲規制突起７１を軸装着板９５側へ伸ばして、この回動範囲規制突起７１を軸装着板９５に別途設けた突起に当接させて回動範囲を規制する等の構成にしてもよい。この場合にも、開閉角度を規制して、故障防止を図ることができる。   In addition, the structure which controls the rotation range of the rotation arm 70 is not restricted to embodiment mentioned above, For example, the positional relationship of the shaft insertion hole 73 of the rotation arm 70 and the rotation range control protrusion 71 in FIG. The rotation range restricting projection 71 is extended to the shaft mounting plate 95 side, and the rotation range restricting projection 71 is brought into contact with a protrusion provided separately on the shaft mounting plate 95 so that the rotation range is set. You may make it the structure which regulates. Also in this case, the opening / closing angle can be regulated to prevent failure.

また、回動アーム７０ａと回転体８１ａとを一体形成し、回動アーム７０ｂと回転体８１ｂとを一体形成してもよい。この場合は、部品点数を削減することができ、コストダウンを図ることができる。   Alternatively, the turning arm 70a and the rotating body 81a may be integrally formed, and the turning arm 70b and the rotating body 81b may be formed integrally. In this case, the number of parts can be reduced, and the cost can be reduced.

また、回動角度係止板５５の代わりに、回動アーム７０に直接係止孔５７を設けても良い。この場合も、部品点数を削減することができ、コストダウンを図ることができる。   Further, instead of the rotation angle locking plate 55, a locking hole 57 may be provided directly in the rotation arm 70. Also in this case, the number of parts can be reduced, and the cost can be reduced.

また、係止突起５２と係止孔５７の配置や個数は、他の構成にしてもよく、例えば全閉状態と全開状態に加えて、１６０°開状態などの途中停止状態で係止できるように構成してもよい。これにより、携帯電話機１の開閉角度を通話の際に使用しやすい角度で係止するといったことができ、利便性を向上させることができる。   Further, the arrangement and number of the locking projections 52 and the locking holes 57 may be other configurations. For example, in addition to the fully closed state and the fully opened state, the locking protrusions 52 and the locking holes 57 can be locked in a halfway stop state such as a 160 ° open state. You may comprise. Thereby, the opening / closing angle of the mobile phone 1 can be locked at an angle that can be easily used during a call, and convenience can be improved.

また、リンク機構部８０と回動アーム７０との関係は、リンク機構部４０が図８（Ｃ）及び図９（Ｃ）の状態で、回動アーム７０が図８（Ａ）及び図９（Ａ）に示したように外側へ真っ直ぐ伸びた状態となるように構成してもよい。この場合は、前述した実施形態とは逆対象に開閉動作することができる。   Further, the relationship between the link mechanism 80 and the rotation arm 70 is that the link mechanism 40 is in the state of FIGS. 8C and 9C, and the rotation arm 70 is in FIGS. You may comprise so that it may be in the state extended straight outside as shown to A). In this case, the opening / closing operation can be performed in a manner opposite to that of the above-described embodiment.
