本発明は、ノート型パソコンや折り畳み式携帯電話などの電子機器の軸部に用いるヒンジ装置並びにこのヒンジ装置を用いた電子機器に関するものである。
The present invention relates to a hinge device used for a shaft portion of an electronic device such as a notebook personal computer or a foldable mobile phone, and an electronic device using the hinge device.
例えば、ノート型パソコンは、操作部を有する本体部とディスプレイ部を有する開閉部とを、軸受部と枢着軸とを軸着して成るヒンジ装置を介して回動自在に枢着する構成となっている。
For example, a notebook computer has a configuration in which a main body portion having an operation portion and an opening / closing portion having a display portion are pivotally attached via a hinge device formed by axially attaching a bearing portion and a pivot attachment shaft. It has become.
このヒンジ装置としては、従来、例えば本体部などの第一部材に連結する第一連結部20に軸受部21を設け、開閉部などの第二部材に連結する第二連結部22に枢着軸23を設け、この枢着軸23を軸受部21に軸着することで第一連結部20に対して第二連結部22を回動自在に設けた軸着構造としているものがある。
As this hinge device, conventionally, for example, a bearing portion 21 is provided in a first connecting portion 20 that is connected to a first member such as a main body portion, and a pivot shaft is attached to a second connecting portion 22 that is connected to a second member such as an opening / closing portion. In some cases, a shaft attachment structure is provided in which a second connection portion 22 is provided so as to be rotatable with respect to the first connection portion 20 by attaching the pivot shaft 23 to the bearing portion 21.
また、この種ヒンジ装置は、組み付けの都合上、枢着軸23と第二連結部22とが別部品とされていて、本体部に第一連結部20を介して組み付けられている軸受部21に軸着した枢着軸23と、開閉部に組み付けられた第二連結部22とを最終的に連結固定できるように構成されているものが多い。
Further, in this type of hinge device, for the convenience of assembly, the pivot shaft 23 and the second connecting portion 22 are separate parts, and the bearing portion 21 is assembled to the main body portion via the first connecting portion 20. In many cases, the pivot shaft 23 that is pivotally attached to the shaft and the second connecting portion 22 assembled to the opening / closing portion can be finally connected and fixed.
一方、近年のノート型パソコンは、筐体の薄型化，小型化が望まれる傾向にあり、これに伴ってヒンジ装置も薄型化，小型化が要求されているが、特にディスプレイ部は薄型化が比較的容易なことから、ディスプレイ部（開閉部）に連結する第二連結部22を薄い板材で構成することでディスプレイ部を薄型化させているものが増えてきている。
On the other hand, in recent years, notebook computers tend to be thinner and smaller in size, and accordingly, hinge devices are also required to be thinner and smaller. Since it is comparatively easy, the thing which made the display part thin is increasing by comprising the 2nd connection part 22 connected with a display part (opening-closing part) with a thin board | plate material.
また、このような小型のヒンジ装置における第二連結部22と枢着軸23との連結固定構造は、第二連結部22の薄さを生かすためにも複雑な構造を採用することは好ましくなく、例えば図６に示すように、第二連結部22の枢着軸23への固定側板部に貫通孔24を形成する一方、枢着軸23の周面部に接合用の平坦面25を凹設してこの接合用平坦面25にネジ孔26を形成し、この貫通孔24とネジ孔26の位置を合わせて第二連結部22の固定側板部を枢着軸23の接合用平坦面25に当接した上で、貫通孔24から通したネジ27をネジ孔26に螺着することで枢着軸23に第二連結部22を固定するようなシンプルな固定構造が採用されている。
In addition, it is not preferable to adopt a complicated structure for connecting and fixing the second connecting portion 22 and the pivot shaft 23 in such a small hinge device in order to make use of the thinness of the second connecting portion 22. For example, as shown in FIG. 6, the through hole 24 is formed in the fixed side plate portion of the second connecting portion 22 to the pivot shaft 23, and the joining flat surface 25 is recessed in the peripheral surface portion of the pivot shaft 23. Then, the screw hole 26 is formed in the bonding flat surface 25, and the position of the through hole 24 and the screw hole 26 is aligned so that the fixed side plate portion of the second connecting portion 22 is connected to the bonding flat surface 25 of the pivot shaft 23. A simple fixing structure is employed in which the second connecting portion 22 is fixed to the pivot shaft 23 by screwing the screw 27 passed through the through hole 24 into the screw hole 26 after the contact.
ところが、このような連結部品（例えば上記従来例においては第二連結部22）が薄い板材で構成されるヒンジ装置にあっては、そもそもこの連結部品22（薄板）自体が高強度を具備するものではない上、開閉部の開閉作動時に連結部品22の貫通孔24部分に応力が集中するために、長期間の使用で開閉部の開閉動作が幾度となく繰り返されていると、この貫通孔24から亀裂が生じて連結部品22が破損してしまう懸念があった。
However, in a hinge device in which such a connecting component (for example, the second connecting portion 22 in the above-described conventional example) is made of a thin plate material, the connecting component 22 (thin plate) itself has high strength in the first place. In addition, since stress concentrates on the through hole 24 portion of the connecting part 22 during the opening / closing operation of the opening / closing part, if the opening / closing operation of the opening / closing part is repeated several times over a long period of use, the through hole 24 Therefore, there is a concern that the connecting part 22 may be broken due to a crack.
本発明は、このような小型のヒンジ装置に生じる懸念を払拭しようとするもので、簡易構造により軸部品と連結部品との固定強度を著しく向上して秀れた耐久性を発揮する画期的なヒンジ装置並びにこのヒンジ装置を用いた電子機器を提供することが技術的課題である。
The present invention is intended to eliminate the concern that arises in such a small hinge device, and has a revolutionary structure that exhibits excellent durability by remarkably improving the fixing strength between the shaft component and the connecting component with a simple structure. It is a technical problem to provide a simple hinge device and an electronic device using the hinge device.

好適と考える本発明の実施形態（発明をどのように実施するか）を、図面に基づいて本発明の作用を示して簡単に説明する。
Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.
本発明のヒンジ装置Ｈは、第一部材１に連結する第一連結部３若しくは前記第二部材２に連結する第二連結部４に軸受部５を設け、第二部材２に連結する第二連結部４若しくは前記第一部材１に連結する第一連結部３に前記軸受部５に軸着する枢着軸６を設けた構成であり、また、第二連結部４若しくは第一連結部３と枢着軸６とは別部品とされて、枢着軸６に設けた接合面部７に第二連結部４若しくは第一連結部３に設けた重合部８を重合し、この重合部８に形成した止着孔９を介して止着具10を枢着軸６に止着することで重合部８を前記接合面部７に重合状態で接合固定しているが、この接合面部７と重合部８の固定に加えて、第二連結部４若しくは第一連結部３に設けた補強用連結部11を枢着軸６の軸方向と相対する方向に配設し、この補強用連結部11と相対する枢着軸６端部に突設した係合突起12を補強用連結部11に設けた挿通部13に挿通係合することで、この補強用連結部11も枢着軸６に固定している。
In the hinge device H of the present invention, the first connecting portion 3 connected to the first member 1 or the second connecting portion 4 connected to the second member 2 is provided with a bearing portion 5 and connected to the second member 2. The first connecting part 3 connected to the connecting part 4 or the first member 1 is provided with a pivot shaft 6 that is pivotally attached to the bearing part 5, and the second connecting part 4 or the first connecting part 3. And the pivoting shaft 6 are separate parts, and the second coupling portion 4 or the overlapping portion 8 provided in the first coupling portion 3 is superposed on the joint surface portion 7 provided on the pivoting shaft 6. The overlapping portion 8 is fixedly bonded to the bonding surface portion 7 in a superposed state by fixing the fastener 10 to the pivot shaft 6 through the formed fixing hole 9. In addition to fixing 8, the reinforcing connecting portion 11 provided in the second connecting portion 4 or the first connecting portion 3 is disposed in a direction opposite to the axial direction of the pivot shaft 6, By inserting and engaging the engaging protrusion 12 projecting from the end of the pivot shaft 6 facing the reinforcing connecting portion 11 with the insertion portion 13 provided in the reinforcing connecting portion 11, the reinforcing connecting portion 11 is also pivoted. The shaft 6 is fixed.
即ち、本発明では、第二連結部４若しくは第一連結部３を、略直交する重合部８と補強連結部11とで枢着軸６に対し略直交する二方向から固定することでこの第二連結部４若しくは第一連結部３に枢着軸６を設けているので、単に連結部品22の固定側板部を枢着軸23の接合用平坦面25に重合してこの固定側板部の一面（一方向）だけを接合用平坦面25にネジ27で接合固定する前記従来例の構成に比べて著しく連結固定強度が向上し、枢着軸６に対する第二連結部４若しくは第一連結部３のガタつきやグラつきが低減することになる。
That is, in the present invention, the second connecting portion 4 or the first connecting portion 3 is fixed in two directions substantially perpendicular to the pivot shaft 6 by the overlapping portion 8 and the reinforcing connecting portion 11 that are substantially orthogonal. Since the pivoting shaft 6 is provided in the second coupling portion 4 or the first coupling portion 3, the fixed side plate portion of the coupling component 22 is simply superposed on the joining flat surface 25 of the pivotal shaft 23, and one surface of this fixed side plate portion is obtained. Compared with the structure of the conventional example in which only (one direction) is bonded and fixed to the flat surface 25 for bonding with the screw 27, the connection fixing strength is remarkably improved, and the second connecting portion 4 or the first connecting portion 3 with respect to the pivot shaft 6 is obtained. The backlash and glare will be reduced.
また、従来例のように、連結部品22の固定側板部の一面だけを枢着軸23の接合用平坦面25にネジ27で接合固定する構成であると、本体部と開閉部の開閉作動時に枢着軸23の回転力を連結部品22が一方向だけで支持することとなるために、連結部品のネジ通し用貫通孔24部分に応力が集中して経年使用によりこの貫通孔24から亀裂が生じてしまう懸念があったが、第二連結部４若しくは第一連結部３の重合部８を、枢着軸６の接合面部７に止着具10で固定することに加えて、この重合部８と略直交状態に設けられた補強用連結部11も、その挿通部13に枢着軸６の係合突起12を挿通係合することで枢着軸６に固定する本発明では、開閉作動時の枢着軸６の回転力を略直交する二方向で支持することになり、この回転力を一方向だけで支持していた従来例に比べて、止着具10を通した止着孔９部位と係合突起12を挿通係合した挿通部13部位とに応力が効果的に分散して亀裂の発生や破損を防止でき、秀れた耐久性を発揮することになる。
Further, as in the conventional example, when only one surface of the fixed side plate portion of the connecting part 22 is joined and fixed to the joining flat surface 25 of the pivot shaft 23 with the screw 27, the opening and closing operation of the main body portion and the opening and closing portion is performed. Since the connecting component 22 supports the rotational force of the pivot shaft 23 in only one direction, stress concentrates on the threaded through-hole 24 portion of the connecting component, and cracks are caused from the through-hole 24 due to aging. In addition to fixing the overlapping portion 8 of the second connecting portion 4 or the first connecting portion 3 to the joining surface portion 7 of the pivot shaft 6 with the fastener 10, In the present invention, the reinforcing connecting portion 11 provided in a state substantially orthogonal to 8 is fixed to the pivot shaft 6 by inserting and engaging the engaging projection 12 of the pivot shaft 6 with the insertion portion 13. In the conventional example, the rotational force of the pivot shaft 6 is supported in two directions substantially orthogonal to each other, and this rotational force is supported in only one direction. In addition, the stress can be effectively distributed to the fastening hole 9 part through the fastening tool 10 and the insertion part 13 part through which the engaging protrusion 12 is inserted and engaged, preventing the occurrence of cracks and breakage. It will show the durability.
しかも本発明は、従来例の構造に対して、前記第二連結部４若しくは前記第一連結部３に、前記重合部８と略直交状態にして挿通部13を有する補強用連結部11を設けると共に、前記枢着軸６の端部に係合突起12を突設して、挿通部13に係合突起12を挿通係合する構成を加えることで構成可能であるので、この構成は簡易構造であり、容易に設計実現可能で量産性にも秀れる。
Moreover, according to the present invention, a reinforcing connecting portion 11 having an insertion portion 13 in a state substantially orthogonal to the overlapping portion 8 is provided in the second connecting portion 4 or the first connecting portion 3 with respect to the structure of the conventional example. At the same time, the structure can be configured by projecting the engaging protrusion 12 at the end of the pivot shaft 6 and inserting and engaging the engaging protrusion 12 with the insertion portion 13. It can be easily designed and mass-produced.
また、例えば、前記第二連結部４若しくは前記第一連結部３の、前記枢着軸６への固定側部を板状に構成し、この板状の固定側部を略直角に折曲形成してこの折曲部14を境にした一側板部を前記重合部８とすると共に他側板部を前記補強用連結部11として、重合部８と補強用連結部11とを略直交状態に設ければ、単に第二連結部４若しくは第一連結部３の板状部を略直角に折曲するだけで重合部８と補強用連結部11とを略直交状態にして設けることができるので、従来例と比べて第二連結部４若しくは第一連結部３の部品点数を何ら増やすことなく、且つ著しい量産性の低下も招くことなく本発明の第二連結部４若しくは第一連結部３を容易に構成可能となる。
In addition, for example, the fixed side portion of the second connecting portion 4 or the first connecting portion 3 to the pivot shaft 6 is formed in a plate shape, and the plate-like fixed side portion is bent at a substantially right angle. The one side plate portion with the bent portion 14 as a boundary is the overlapping portion 8 and the other side plate portion is the reinforcing connecting portion 11, and the overlapping portion 8 and the reinforcing connecting portion 11 are provided in a substantially orthogonal state. Then, the overlapping portion 8 and the reinforcing connecting portion 11 can be provided in a substantially orthogonal state simply by bending the second connecting portion 4 or the plate-like portion of the first connecting portion 3 at a substantially right angle. Compared to the conventional example, the second connecting part 4 or the first connecting part 3 of the present invention can be used without increasing the number of parts of the second connecting part 4 or the first connecting part 3 and without causing a significant decrease in mass productivity. It can be easily configured.
また、例えば、前記第二連結部４若しくは前記第一連結部３は板金製とし、この第二連結部４若しくは第一連結部３の、前記枢着軸６への固定側板部を略直角に折曲形成してこの折曲部14を境にした一側板部を前記重合部８とすると共に他側板部を前記補強用連結部11として、重合部８と補強用連結部11とを略直交状態に設け、この補強用連結部11に貫通孔13を形成してこの貫通孔13を前記挿通部13とし、この挿通部13に挿通させた前記枢着軸６端部の前記係合突起12の突出先端部を圧潰することで補強用連結部11を枢着軸６にカシメ止めする構成とすれば、略直交状態の重合部８と補強用連結部11とを具備する第二連結部４若しくは第一連結部３を簡易に設計実現可能であると共に、第二連結部４若しくは第一連結部３が板金であるため小型化が容易で薄型，小型の電子機器用に適したヒンジ装置Ｈとなり、しかも、板金製の補強用連結部11に孔を貫通形成するだけで挿通部13を構成可能であるため、従来例と比べて部品点数を何ら増やすことなく製作容易で量産性にも秀れることとなる。
Further, for example, the second connecting part 4 or the first connecting part 3 is made of sheet metal, and the fixed side plate part of the second connecting part 4 or the first connecting part 3 to the pivot shaft 6 is set at a substantially right angle. The one side plate portion formed by bending and having the bent portion 14 as a boundary is the overlapping portion 8 and the other side plate portion is the reinforcing connecting portion 11, and the overlapping portion 8 and the reinforcing connecting portion 11 are substantially orthogonal to each other. The through-hole 13 is formed in the reinforcing connecting portion 11, and the through-hole 13 is used as the insertion portion 13, and the engaging protrusion 12 at the end of the pivot shaft 6 inserted through the insertion portion 13 is provided. If the reinforcing connecting portion 11 is crimped to the pivot shaft 6 by crushing the protruding tip of the second connecting portion 4, the overlapping connecting portion 8 and the reinforcing connecting portion 11 are in a substantially orthogonal state. Alternatively, the first connecting portion 3 can be easily designed and realized, and the second connecting portion 4 or the first connecting portion 3 is a sheet metal, so that the size can be reduced. Compared to the conventional example, the hinge device H is easy, thin, and suitable for small-sized electronic devices, and the insertion portion 13 can be configured simply by penetrating a hole in the reinforcing connecting portion 11 made of sheet metal.
