These opening / closing engagement recesses 28a, 28b, 28c are for positioning the monitor 3 at a predetermined visual recognition position, and the interval (angle) is appropriately determined.
- the monitor 3 can be rotated about the first axis X with respect to the bracket 26 by the opening / closing shaft 24, and the opening / closing leaf spring 25 is elastically pressed against the bracket 26 by the opening / closing engagement convex portion 25a. Therefore, it has an appropriate sliding resistance and is opened and closed with an appropriate torque.
- an opening / closing stopper 27 is formed at the edge of the bracket 26 on the opening / closing engagement recess 28a side.
- the opening / closing stopper 27 prevents the monitor 3 from opening and closing more than a predetermined amount when the opening / closing leaf spring 25 attached to the tip of the opening / closing shaft 24 hits. Since the monitor opening / closing mechanism 200 includes two opening / closing shafts 24 parallel to the first axis X direction, vibration resistance is high and rattling is unlikely to occur.
- the monitor rotating mechanism 100 includes the sub-base 14 fixed to the base 21 of the monitor opening / closing mechanism 200, one end fixed to the upper surface 3c of the monitor 3, and the other end connected to the sub-base 14.
- a cylindrical boss 11 supported by the base 14 so as to be rotatable about the second axis Y, and a bush 34 having one end fixed to the base 21 and inserted into the boss 11 to pivotally support the boss 11 are provided. It was configured as follows. Therefore, even if vibration is applied to the biaxial hinge mechanism, the boss 11 is inclined to the bush 34 in the range of the gap K, and the leaf springs 13 and 15 can be prevented from being bent and rattling. As a result, the rigidity of the monitor rotation mechanism 100 is increased, and rattling due to vibration can be prevented, and the shake of the monitor 3 can be suppressed.
- the bush 34 was formed to a length up to the middle of the boss 11. For this reason, the bush 34 can be completely inserted into the boss 11 without contacting the bulging portion 35 of the boss 11. Therefore, the rotational performance of the boss 11 with respect to the bush 34 can be stabilized.
- a groove 34a was provided on the outer peripheral surface of the bush 34, and an O-ring 36 was inserted into the groove 34a. For this reason, even if vibration is applied to the biaxial hinge mechanism, the O-ring 36 acts as a buffer, and the occurrence of a collision sound between the boss 11 and the bush 34 can be prevented.
- the bush 34 is cylindrical, the wiring member 37 for connecting the monitor 3 and the main board can be inserted into the bush 34.
- the groove 34a for inserting the O-ring 36 for preventing the collision noise is provided around the outer peripheral surface of the bush 34.
- the groove is formed around the inner peripheral surface of the boss 11. It is good also as a structure which installs and inserts an O-ring. Further, instead of the O-ring, a highly viscous fluid such as silicone oil may be put into the groove.
- the biaxial hinge mechanism includes the monitor opening / closing mechanism and the monitor rotation mechanism in order to prevent the monitor rotation mechanism from shaking and suppressing the shake of the monitor. Since the rotation mechanism is configured to include a sub-base, a cylindrical boss, and a bush that pivotally supports the boss, the rotation mechanism is suitable for use in a biaxial hinge mechanism used for opening and closing a monitor installed in an automobile.

Abstract
Description
ボス11には、リング状の押さえプレート12および板ばね13と、サブベース14と、同じくリング状の板ばね15および押さえプレート16とがこの順に通されている。ボス11の周溝11cの縁をかしめてかしめ部11dを形成することによってボス11がサブベース14に固定される。このサブベース14は、ねじ17によりモニタ開閉機構200のベース21に固定されている。
押さえプレート16の内周は周溝11cに嵌合する径で形成され、押さえプレート16が周溝11cに嵌合することにより上側への移動が規制されている。さらに、押さえプレート16が周溝11cに固定されることによって、押さえプレート16と保持部11bとで形成される保持幅H(図9A)が決定される。この保持幅H部分に押さえプレート12、板ばね13、サブベース14および板ばね15が取り付けられており、これらが保持部11bと押さえプレート16によって上下方向から挟持される。
よって、モニタ3は、ボス11によりサブベース14に対し第2軸Yを中心として自転回動可能であり、しかも板ばね13,15でサブベース14に弾力的に押し付けられているので、適度な摺動抵抗をもち、適度なトルクを必要として自転回動される。
実施の形態1.
以下、この発明の実施の形態1を、図面を参照しながら詳細に説明する。なお、以下の実施の形態の説明において、先立って説明した従来技術(図7-図9B)の構成要素と同一または相当するものには同一の符号を付し、説明を省略する。
図6(a)に示す、当て部32の位置を基準位置とする。この基準位置のときモニタ3は正規の状態にある。図6(a)に示すように、押さえプレート16の当て部32は、板ばね13,15の係合凸部13b,15bがサブベース14の係合孔14bと係合したときに、ストッパ31に当たる位置、または若干の隙間が存在する位置に形成されている。従って、図6(a)に示す基準位置からモニタ3を自転回動させれば、モニタ3と共にボス11がブッシュ34に軸支されながら回動し、さらにボス11に嵌合した押さえプレート16の当て部32も回動する。そのとき、突出部33は当て部32より径方向の長さが短いためストッパ31に当たることがない(図6(b))。基準位置から図6(c)に示す位置まで、当て部32が180度回動すれば、係合凸部13b,15bが係合孔14bに係合して位置決めされ、更に同方向に回動しようとしても当て部32がストッパ31に当たってそれ以上回動しないようになっている。このとき、モニタ3は180度自転回動して反転状態にある。
このように当て部32がストッパ31に当たることにより、モニタ3の回転角が180度に規制されると共に、回転可能な方向が一方向に規制される。そのため、ボス11およびブッシュ34の内部を挿通する配線部材37のねじれ角も180度以内となり、ねじれ断線を防止することができる。
モニタ収納ケース2には所定の間隔をあけて一対のブラケット26が設けられている。一方、ベース21の両端には接続部23がそれぞれ取り付けられ、これらの接続部23に、一直線上に開閉軸24がそれぞれ設けられている。開閉軸24の先端には開閉板ばね25が開閉軸24と一体に回転するように取り付けられている。また、開閉軸24と開閉板ばね25との間にブラケット26が取り付けられている。開閉板ばね25のブラケット26側の面には開閉係合凸部25aが設けられてあり、この開閉係合凸部25aが、開閉板ばね25が有する弾性力によりブラケット26に弾力的に押し付けられる。他方のブラケット26には円周方向に所定間隔で開閉係合凹部28a,28b,28cが設けられている。これら開閉係合凹部28a,28b,28cは、モニタ3を所定の視認位置に位置決めするためのものであり、間隔(角度)は適宜決められる。
よって、モニタ3は、開閉軸24によりブラケット26に対し第1軸Xを中心として回動可能であり、しかも開閉板ばね25が開閉係合凸部25aでブラケット26に弾力的に押し付けられているので、適度な摺動抵抗をもち、適度なトルクを必要として開閉される。
なお、モニタ開閉機構200は第1軸X方向に平行な2つの開閉軸24を備えているため、耐振動性が高く、がたつきが発生しにくい。
また、Oリングに代えて、シリコンオイル等の粘性の高い流体を溝に入れ込んでもよい。
