Description

本発明は、2つの筐体に取付けて二つ折に折畳み開閉できるヒンジ装置を用いた携帯電話やノート型パソコンなどの折畳み式電子機器に関するものである。   The present invention relates to a foldable electronic device such as a mobile phone or a notebook computer using a hinge device that can be attached to two housings and folded and opened in two.

従来のこの種のヒンジ装置としては、2つの筐体の一方側に軸を支持する回動支持部材を設け、他方側に前記軸が嵌合される軸受部を設け、2つの筐体を1本の軸で回転自在に軸支したもの、或いは、2本の軸で軸支したものが知られている(例えば、特許文献1、2参照)。
特開2004−52892号公報 特開2004−308710号公報(図1、図4、図5、段落〔0010〕〜〔0015〕)
As a conventional hinge device of this type, a rotation support member for supporting a shaft is provided on one side of two housings, and a bearing portion to which the shaft is fitted is provided on the other side, and two housings are provided as 1 One that is rotatably supported by two shafts or one that is supported by two shafts is known (see, for example, Patent Documents 1 and 2).
JP 2004-52892 A JP 2004-308710 A (FIGS. 1, 4, and 5, paragraphs [0010] to [0015])

上記特許文献1に記載されたヒンジ装置は、2つの筐体が共通の1本の支軸で回転自在に保持された構成を有しており、この構成によると、軸部を一方の筐体内に設けたとしても他方の筐体からは突出したアーム部が必要となり、また、軸部を各筐体の外に設けたとしても、軸部が突出した形状となる。このため、二つ折の筐体を開いたとき、そのアーム部又は軸部が突出してしまい、その開き面が連続した平面状にならず突出したものとなる。この点、上記特許文献2に記載されたヒンジ装置は、2つの筐体が2本の軸で軸支されているので、筐体の連結部が突起することがなく、開状態において開き面がフラットになる。   The hinge device described in Patent Document 1 has a configuration in which two casings are rotatably held by a common spindle, and according to this configuration, the shaft portion is placed in one casing. Even if it is provided, an arm portion protruding from the other housing is required, and even if the shaft portion is provided outside each housing, the shape of the shaft portion protrudes. For this reason, when the two-fold housing is opened, the arm portion or the shaft portion protrudes, and the opening surface does not become a continuous flat shape but protrudes. In this regard, in the hinge device described in Patent Document 2, since the two housings are pivotally supported by two shafts, the connecting portion of the housing does not protrude, and the open surface is open in the open state. Become flat.

しかし、このヒンジ装置は、2本の軸で軸支された一対のヒンジ機構が連結部材に対して個別に作動するので、2つの筐体が折畳まれたとき、筐体がスライドしてしまい、両筐体が同一形状のときに、折畳み時にぴったり重ならず、一方の筐体が他の筐体からはみ出しズレることがある。   However, in this hinge device, since a pair of hinge mechanisms pivotally supported by two shafts individually operate with respect to the connecting member, the housing slides when the two housings are folded. When both housings have the same shape, they do not overlap exactly when folded, and one housing may protrude from the other housing.

このようなズレが発生すると、ユーザーにあたかも欠陥品かのような不安感を与え、また、そのズレを直すために各筐体をスライド移動させて重なった状態にしなければならず、ユーザーに余分な操作を強いることになる。また、一対のヒンジ機構が独立で作動するため、何れかのヒンジ機構がフレームの壁面等に突き当たり、以降の回動が阻止されるタイミングが各ヒンジ機構で異なるため、開閉動作が常に一定とならず、また何れかのヒンジ機構が開閉動作の途中で壁面に突き当たり、回動が阻止されるとユーザーに違和感を生じさせ、スムーズな開閉を行うことができない恐れがある。   When such a shift occurs, the user is given anxiety as if it is a defective product, and in order to correct the shift, the housings must be slid to overlap each other. Will be forced to operate. In addition, since the pair of hinge mechanisms operate independently, the timing at which one of the hinge mechanisms hits the wall surface of the frame and the subsequent rotation is prevented is different for each hinge mechanism. In addition, if any of the hinge mechanisms hits the wall surface in the middle of the opening / closing operation and the rotation is prevented, the user may feel uncomfortable and the opening / closing may not be performed smoothly.

本発明は、このような従来技術が抱える課題を解決するためになされたものであって、本発明の目的は、折畳み時にズレが発生しない安定感のある折畳み作動を可能としたヒンジ装置を用いた折畳み式電子機器を提供することにある。   The present invention has been made in order to solve the above-described problems of the prior art, and an object of the present invention is to use a hinge device that enables a stable folding operation that does not cause misalignment during folding. It is to provide a foldable electronic device.

The first mounting frame mounted on the first housing side, the second mounting frame mounted on the second housing side, and the distal end side of the first mounting frame and the second mounting frame rotate in the approaching and separating directions. The base end of each frame is pivotally supported via a first main shaft and a second main shaft arranged in parallel to each other to transmit the rotation of each frame , and the first main shaft And a third mounting frame having an upper side parallel to the second main axis, a first side and a second side formed at the left and right ends thereof , and the first main axis and the second main axis Are connected to each other, and reverse rotation force is transmitted from one of them to the other. Rotation consists of a rotation force transmission mechanism having a function of a cam surface formed on the first side edge, and the first spindle integrally with the rotary cam follower for resiliently engaging said cam surface An angle restricting means, and by disposing the first main shaft and the second main shaft in each recess formed at a joint portion of the first housing and the second housing which are folded in two, It is characterized in that the open surfaces of the respective casings are continuous and substantially flat. The invention according to claim 2 is a foldable electronic device including a hinge device that opens and closes the first housing and the second housing in two folds, the hinge device on the first housing side. A first mounting frame attached to the
A base end portion of each of the frames is attached so that the second attachment frame attached to the second housing side and the distal end portions of the first attachment frame and the second attachment frame can be rotated in the approaching and separating directions. Rotating shafts are supported via a first main shaft and a second main shaft that are arranged in parallel to each other to transmit the rotation of each frame, and the upper side that is parallel to the first main shaft and the second main shaft and the left and right ends thereof A third mounting frame having a first side and a second side formed, and the first main shaft and the second main shaft are connected to each other. A rotational force transmission mechanism having a transmission function and arranged in parallel with the first side, a cam surface formed on the outer side of the first side, and the first main shaft are integrally rotated. Rotation angle comprising a cam follower that elastically engages the cam surface And a biasing means for biasing the cam follower in a direction in which the cam surface exists, and a cam follower are inserted into the first main shaft, and the cam follower is inserted into the first main shaft by the biasing means. The first main shaft and the second main shaft are inserted into the recesses formed at the joint portions of the first housing and the second housing which are engaged with the cam surface and the rotation angle restricting means functions. Are arranged so that the open surfaces of the casings are continuous and substantially flat.

また、本発明は、前記回転伝達機構は、前記第1、第2主軸に設けた第1、第2歯車と、前記第1、第2歯車間に介在させた偶数個の歯車と有し、前記第1、第2歯車及び前記偶数個の歯車はそれぞれ歯車列をなして連結したものである。   Further, in the present invention, the rotation transmission mechanism includes first and second gears provided on the first and second main shafts, and an even number of gears interposed between the first and second gears, The first and second gears and the even number of gears are connected in a gear train.

更に、本発明は、前記回転伝達機構は、前記第1、第2主軸に設けた前記第1、第2歯車と、前記第1、第2歯車に反転回転力を伝達する反転回転力伝達手段で構成されているものである。   Further, according to the present invention, the rotation transmission mechanism includes a first and second gears provided on the first and second main shafts, and a reverse torque transmission means for transmitting a reverse torque to the first and second gears. It is composed of.

本発明の折畳み式電子機器によれば、第1筐体側の第1取付フレーム及び第2筐体側の第2取付フレームは、第1、第2主軸を介して第3取付フレームに支軸され、第1、第2主軸は反転回転力を伝達する回転力伝達機構で連結されているので、例えば第1取付フレームの第3取付フレームを基軸とする一方向への回動に伴って、第2取付フレームが同じく第3取付フレームを基軸として逆方向に回動するため、筐体の開動動作がスムーズになる。また、第1取付フレームの回動と第2取付フレームとの回動が連動するため、従来技術では折畳み機器を折畳んだ状態においてこの2軸が独立していると筐体同士の位置にズレが生じることがあるが、この発明では回転力伝達機構によってこの2軸が連動するため、このようなズレが生じることがない。すなわち、例えば、このヒンジ装置を折畳み式携帯電話機に適用すると、携帯電話機の上下筐体の位置ズレが発生せず、ユーザーに安定感を与えることができる。   According to the foldable electronic device of the present invention, the first mounting frame on the first housing side and the second mounting frame on the second housing side are supported by the third mounting frame via the first and second main shafts, Since the first and second main shafts are connected by a rotational force transmission mechanism that transmits the reverse rotational force, for example, as the first attachment frame rotates in one direction with the third attachment frame as a base axis, Similarly, since the mounting frame rotates in the reverse direction with the third mounting frame as a base axis, the opening operation of the housing becomes smooth. In addition, since the rotation of the first mounting frame and the rotation of the second mounting frame are interlocked with each other, in the conventional technique, when the two axes are independent in a state in which the folding device is folded, the positions of the casings are shifted. However, in the present invention, since the two axes are interlocked by the rotational force transmission mechanism, such a deviation does not occur. That is, for example, when this hinge device is applied to a foldable mobile phone, a positional deviation between the upper and lower casings of the mobile phone does not occur and a sense of stability can be given to the user.

また、第1、第2主軸はそれぞれ第1、第2筐体内に内蔵されるので、従来技術のように主軸部の凹凸が無くなる。このため、2つの筐体の開き面を連続した平面状にすることができる。更に、第1主軸及び第2主軸との間を互いに反転回転力を伝達する機構により連結し、かつ回転角度規制手段を配置したので、開き面が連続平面状で薄型化しつつ、二つ折りの第1筐体又は第2筐体の開閉動作にスナップアクションが得られる。   Further, since the first and second main shafts are built in the first and second housings, respectively, the unevenness of the main shaft portion is eliminated as in the prior art. For this reason, the open surfaces of the two housings can be formed into a continuous flat shape. Further, since the first main shaft and the second main shaft are connected by a mechanism that transmits the reverse rotational force to each other and the rotation angle restricting means is disposed, the opening surface is continuously flat and thinned, and the second folded second A snap action can be obtained for the opening / closing operation of the one casing or the second casing.

また、この折畳み式電子機器によれば、第1、第2取付フレームのいずれか一方の取付フレームの回動に伴って他方の取付フレームが逆方向は回動されるので、第1、第2筐体の開動動作がスムーズになり、また、偶数個の歯車を第3取付フレームに千鳥状に配置・固定することにより、第1、第2歯車の支軸間の距離を短くできるので、機器の薄型化が可能となる。更に、第1、第2歯車を小径にできるので、第1、第2筐体に突出部を設けることなく、各筐体の凹所内に収納することができる。   Further, according to this foldable electronic device, since the other mounting frame is rotated in the reverse direction as one of the first and second mounting frames is rotated, the first and second mounting frames are rotated. The opening movement of the housing is smooth, and the distance between the support shafts of the first and second gears can be shortened by arranging and fixing an even number of gears in a staggered manner on the third mounting frame. Can be made thinner. Furthermore, since the first and second gears can be reduced in diameter, the first and second housings can be accommodated in the recesses of the respective housings without providing protrusions.

On one side 32, a shaft hole 33 that supports the first main shaft 40, a shaft hole 34 that supports the second main shaft 50, shaft holes 35 and 36 that support the gears 81 and 82, and A cam surface 61 of the rotation angle restricting means 60 is provided. The shaft hole 35 and the shaft hole 36 are arranged between the shaft hole 33 and the shaft hole 34 in a staggered manner. With this arrangement, even if gears 81 and 82 having a predetermined outer diameter are used, the distance between the shaft hole 33 and the shaft hole 34 can be shortened, and the portable electronic device 1 can be thinned.

また、他方の側辺32には、第1枢軸42が支持される軸孔37と、第2枢軸52が支持される軸孔38とが設けられている。更に上辺31には、補助取付フレーム70を固定するためのネジ穴39と、前記カバー4を取付けるための開口31aが設けられている。   Further, the other side 32 is provided with a shaft hole 37 for supporting the first pivot 42 and a shaft hole 38 for supporting the second pivot 52. Furthermore, the upper side 31 is provided with a screw hole 39 for fixing the auxiliary mounting frame 70 and an opening 31a for mounting the cover 4.

第3取付フレーム30の一対の側辺32、32は、第1取付フレーム10の一対の基端部11、11間及び第2取付フレーム20の一対の基端部21、21間に位置するように上辺31の長さで調節されている。   The pair of side sides 32, 32 of the third mounting frame 30 are located between the pair of base end portions 11, 11 of the first mounting frame 10 and between the pair of base end portions 21, 21 of the second mounting frame 20. The length of the upper side 31 is adjusted.

回転角度規制手段60は、図4、5に示すように、カム面61とカムフォロワー62とを含み、カムフォロワー62をカム面61に弾性的に係合させ、かつ、第2取付フレーム20の回転と連動させるために、カップリング63、スリーブ64、伸張スプリング65、及び止めワッシャ66が設けられている。   As shown in FIGS. 4 and 5, the rotation angle restricting means 60 includes a cam surface 61 and a cam follower 62, elastically engages the cam follower 62 with the cam surface 61, and the second mounting frame 20. A coupling 63, a sleeve 64, an extension spring 65, and a stop washer 66 are provided for interlocking with the rotation.

この回転角度規制手段60の組み立ては、先ず、第3取付フレーム30の軸孔34に、第2主軸50の手前側軸部を差し込み、この軸部に、カムフォロワー62、カップリング63、及びスリーブ64を嵌め込み、次いで、この軸部先端側を第2取付フレーム20の大径軸孔24に通し、この軸部先端側に伸張スプリング65を嵌め込むことによって行われる。この伸張スプリング65は軸方向に移動自在なスリーブ64を介してカムフォロワー62に押圧力を与える。第2主軸50の奥側軸部は、補助取付フレーム70の軸孔74に嵌め込まれる。   In assembling the rotation angle restricting means 60, first, the front shaft portion of the second main shaft 50 is inserted into the shaft hole 34 of the third mounting frame 30, and the cam follower 62, the coupling 63, and the sleeve are inserted into this shaft portion. 64, and then the shaft tip end side is passed through the large-diameter shaft hole 24 of the second mounting frame 20, and the extension spring 65 is fitted into the shaft tip end side. The extension spring 65 applies a pressing force to the cam follower 62 via a sleeve 64 that is movable in the axial direction. The back shaft portion of the second main shaft 50 is fitted into the shaft hole 74 of the auxiliary mounting frame 70.

この回転角度規制手段60は、第1取付フレーム10と第2取付フレーム20とが相対的に回転して開閉するとき、一つの状態から他の状態に移行するときに、回転初期に負荷が大きくなり、それを乗り越えると負荷が小さくなり、閉状態と開状態とで安定したものとなるように機能する。こうして、二つ折りの各筐体2、3の開閉動作は、スナップアクションが利いたものとなる。   The rotation angle restricting means 60 has a large load at the beginning of rotation when the first mounting frame 10 and the second mounting frame 20 are rotated and opened relative to each other, and when transitioning from one state to another state. Overcoming that, the load is reduced and functions to be stable in the closed state and the open state. Thus, the opening / closing operation of each of the two folded casings 2 and 3 has a snap action.

補助取付フレーム70は、図4、図5に示すように、第3取付フレーム30の一方の側辺32との間に各歯車41、81、82、51を支持するためのもので、上辺71と側辺72とから成り、上辺71には固定用ネジ77が挿通されるネジ穴79と、開口31aに対応する開口70aとが設けられている。また、側辺72には第1主軸40を軸支する軸孔73と、第2主軸50を軸支する軸孔74と、歯車81、82を軸支する軸孔75、76とが設けられている。   As shown in FIGS. 4 and 5, the auxiliary mounting frame 70 is for supporting the gears 41, 81, 82, 51 between one side 32 of the third mounting frame 30, and the upper side 71. The upper side 71 is provided with a screw hole 79 through which the fixing screw 77 is inserted, and an opening 70a corresponding to the opening 31a. The side 72 is provided with a shaft hole 73 that supports the first main shaft 40, a shaft hole 74 that supports the second main shaft 50, and shaft holes 75 and 76 that support the gears 81 and 82. ing.

また、第3取付フレーム30の他方の側辺32(図4で奥側のもの)は、第1取付フレーム10及び第2取付フレーム20の各他方の基端部11、21(図4で奥側のもの)を第1及び第2枢軸42、52を介して軸支するものである。第1及び第2枢軸42、52には、スリーブ43、53がそれぞれ嵌め込まれ、第1取付フレーム10及び第2取付フレーム20の各他方の基端部11、21と第3取付フレーム30の他方の側辺32とを所定の間隔に保持している。この間隔は、化粧カバー4の側面が通る空間となる。   Further, the other side 32 (the rear side in FIG. 4) of the third mounting frame 30 is connected to the other base end portions 11 and 21 (the rear side in FIG. 4) of the first mounting frame 10 and the second mounting frame 20. Side) is pivotally supported via the first and second pivots 42 and 52. Sleeves 43, 53 are fitted into the first and second pivots 42, 52, respectively, and the other base end portions 11, 21 of the first mounting frame 10 and the second mounting frame 20 and the other of the third mounting frame 30. The side 32 is held at a predetermined interval. This interval becomes a space through which the side surface of the decorative cover 4 passes.

回転力伝達機構80は、歯車41、51が第1及び第2主軸40、50にそれぞれ固定され、歯車81、82が中心支持軸に対して回転自在に設けられている。歯車41、歯車81、歯車82及び歯車51は、偶数の歯車列で構成されている。   In the rotational force transmission mechanism 80, the gears 41 and 51 are fixed to the first and second main shafts 40 and 50, respectively, and the gears 81 and 82 are rotatably provided with respect to the center support shaft. The gear 41, the gear 81, the gear 82, and the gear 51 are configured by an even number of gear trains.

この偶数の歯車列からなる回転力伝達機構80が第1取付フレーム10と第2取付フレーム20との間に設けられると、第1取付フレーム10又は第2取付フレーム20のいずれか一方に回転力が加わると、他方に反転回転力を伝達する機能となる。すなわち、第1取付フレーム10に回転力が加わると、第1主軸40が回転し、歯車41が回転し、その回転は歯車81、82を介して歯車51に伝達される。歯車51が回転すると、第2主軸50が回転し、それに結合されているカムフォロワー62、及びカップリング63が回転し、カップリング63が係合している第2取付フレーム20が回転する。このとき、カムフォロワー62はカム面61に弾性的に係合しており、回転角度規制手段60が機能する。(図3、図5参照)。   When the rotational force transmission mechanism 80 including the even number of gear trains is provided between the first mounting frame 10 and the second mounting frame 20, the rotational force is applied to either the first mounting frame 10 or the second mounting frame 20. Is added, the reverse rotation force is transmitted to the other. That is, when a rotational force is applied to the first mounting frame 10, the first main shaft 40 rotates, the gear 41 rotates, and the rotation is transmitted to the gear 51 via the gears 81 and 82. When the gear 51 rotates, the second main shaft 50 rotates, the cam follower 62 and the coupling 63 coupled thereto rotate, and the second mounting frame 20 with which the coupling 63 is engaged rotates. At this time, the cam follower 62 is elastically engaged with the cam surface 61, and the rotation angle restricting means 60 functions. (See FIGS. 3 and 5).

図6(a)〜図6(c)は、第1筐体2(取付フレーム10)に対して第2筐体3(第2取付フレーム20)を、閉じ状態から開いていったときのヒンジ装置5の動作を示している。第1筐体2及び第2筐体3を開いていったとき、その開き面は連続した平面状となることが分かる。これは、2つの軸、すなわち、第1取付フレーム10の第1主軸40及び第2取付フレーム20の第2主軸50を、いずれも第1筐体2及び第2筐体3の各凹所内に収納し、第3取付フレーム30でもって各軸を支持したからである。詳述すると、両主軸の歯車41、51の間が歯車81、82を含む回転力伝達機構80により連結されているので、両主軸の歯車41、51を小径化することができ、両主軸の歯車41、51は第1筐体2及び第2筐体3に突出部を設けることなく、各凹所内に収納することができるからである。   6A to 6C show a hinge when the second housing 3 (second mounting frame 20) is opened from the closed state with respect to the first housing 2 (mounting frame 10). The operation of the device 5 is shown. When the 1st housing | casing 2 and the 2nd housing | casing 3 are opened, it turns out that the open surface becomes a continuous planar shape. This is because two shafts, that is, the first main shaft 40 of the first mounting frame 10 and the second main shaft 50 of the second mounting frame 20 are both in the respective recesses of the first housing 2 and the second housing 3. This is because the shafts are accommodated and supported by the third mounting frame 30. More specifically, since the gears 41 and 51 of both spindles are connected by the rotational force transmission mechanism 80 including the gears 81 and 82, the diameters of the gears 41 and 51 of both spindles can be reduced. This is because the gears 41 and 51 can be housed in the respective recesses without providing the first housing 2 and the second housing 3 with protrusions.

第1、第2取付フレーム10、20は、第1、第2主軸40、50を介して第3取付フレーム30に支軸され、各第1、第2主軸は反転回転力を伝達する回転力伝達機構80で連結されているので、例えば第1取付フレーム10の第3取付フレーム30を基軸とする一方向への回動に伴って、第2取付フレーム20が同じく第3取付フレーム30を基軸として逆方向に回動するため、筐体の開動動作がスムーズになる。また、第1取付フレーム10の回動と第2取付フレーム20との回動が連動するため、従来技術では折畳み機器を折畳んだ状態においてこの2軸が独立していると筐体同士の位置にズレが生じることがあるが、この構成では回転力伝達機構によってこの2軸が連動するため、このようなズレが生じることがない。すなわち、携帯電話機の上下筐体の位置ズレが発生せず、ユーザーに安定感を与えることができる。   The first and second mounting frames 10 and 20 are supported by the third mounting frame 30 via first and second main shafts 40 and 50, and the first and second main shafts are rotational forces that transmit reverse rotational force. Since it is connected by the transmission mechanism 80, for example, the second mounting frame 20 similarly uses the third mounting frame 30 as the base when the first mounting frame 10 rotates in one direction with the third mounting frame 30 as the base. Therefore, the opening operation of the housing is smooth. In addition, since the rotation of the first mounting frame 10 and the rotation of the second mounting frame 20 are interlocked, if the two axes are independent in the state in which the folding device is folded in the conventional technique, the positions of the housings In this configuration, since the two axes are interlocked by the rotational force transmission mechanism, such a deviation does not occur. That is, there is no positional deviation between the upper and lower casings of the mobile phone, and a sense of stability can be given to the user.

しかも、回転力伝達機構80に回転角度規制手段60を設けたので、上記のように開き面を連続平面状で薄型化しつつ、各筐体2、3の開閉動作にスナップアクションが得られる。   In addition, since the rotational angle restricting means 60 is provided in the rotational force transmission mechanism 80, a snap action can be obtained in the opening and closing operations of the housings 2 and 3 while making the opening surface thin and continuous as described above.

なお、本発明は、上記実施形態の構成に限られるものではなく、具体的構成は適宜設計し得るものであり、例えば、第1筐体2及び第2筐体3と、第1取付フレーム10及び第2取付フレーム20との関係は、上記と逆になってもよく、また、回転角度規制手段60は上記実施例では第2取付フレーム20側に設けているが、第1取付フレーム10側に設けてもよく、又は両方の取付フレームに設けることもできる。また、上記では、補助取付フレーム70を用いた実施形態を示したが、この補助取付フレーム70を省いても実施し得る。本発明は、二つ折りの筐体にそれぞれ収納した第1及び第2の取付フレームの基端部が第3の取付フレームを介して平行な2軸に保持され、この2軸に設けた歯車間を偶数の歯車で連結した構成が基本構成であり、このような基本構成を有するものは本発明に含まれる。   In addition, this invention is not restricted to the structure of the said embodiment, A concrete structure can be designed suitably, for example, the 1st housing | casing 2 and the 2nd housing | casing 3, and the 1st attachment frame 10 are used. And the relationship with the second mounting frame 20 may be the reverse of the above, and the rotation angle restricting means 60 is provided on the second mounting frame 20 side in the above embodiment, but on the first mounting frame 10 side. Or may be provided on both mounting frames. Moreover, although the embodiment using the auxiliary mounting frame 70 has been described above, the embodiment can be carried out even if the auxiliary mounting frame 70 is omitted. In the present invention, the base end portions of the first and second mounting frames respectively housed in the two-fold housing are held on two parallel axes via the third mounting frame, and the gears provided on the two axes are arranged. A configuration in which the gears are connected by an even number of gears is a basic configuration, and those having such a basic configuration are included in the present invention.
