Description

この発明は、車載情報機器のスクリーン部を保持する機構におけるばねの保持構造に関するものである。   The present invention relates to a spring holding structure in a mechanism for holding a screen portion of an in-vehicle information device.

近年の乗用車では、車室内に、テレビ、ＤＶＤ、ゲームなどの車載情報機器が設置されるものがある。例えば３列シートや対面シートなどを備えている車両などにおいては、車載情報機器は車室内の天井面などに設けられる。このような車載情報機器は、車載情報機器本体とこの車載情報機器本体に対し回動可能なスクリーン部（ディスプレイ）とからなる。スクリーン部は、車載情報機器本体に対し回動可能でかつ所定の角度に保持して使われる。   Some passenger cars in recent years have in-vehicle information devices such as televisions, DVDs, and games installed in the passenger compartment. For example, in a vehicle equipped with a three-row seat, a facing seat, and the like, the in-vehicle information device is provided on the ceiling surface of the vehicle interior. Such an in-vehicle information device includes an in-vehicle information device main body and a screen portion (display) that is rotatable with respect to the in-vehicle information device main body. The screen unit is rotatable with respect to the in-vehicle information device main body and is used while being held at a predetermined angle.

スクリーン部は、スクリーン部の端部両側面に設けられたシャフトを、車載情報機器本体側に固定されるブラケットで支持するヒンジ機構により回動可能に支持される。スクリーン部は、所定の開角度で位置決め機構により位置決め保持される。スクリーン部は、車載機器情報本体側に収納されるが、ロック機構によりその収納状態で保持される。   The screen portion is rotatably supported by a hinge mechanism that supports shafts provided on both side surfaces of the end portion of the screen portion with brackets fixed to the in-vehicle information device main body. The screen portion is positioned and held by a positioning mechanism at a predetermined opening angle. The screen unit is stored on the in-vehicle device information main body side, but is held in the stored state by the lock mechanism.

このロック機構は、スクリーン部の回動端面に係合穴を設ける一方、車載情報機器本体側にレバーを回動可能に支持すると共に、このレバーにそのフック部が係合穴に入るようにばね力を付与した構造となっており、レバーのフック部が係合穴に係合することによりスクリーン部は収納された状態で保持（ロック）される。スクリーン部を開く場合には、車載情報機器本体側に設けたボタンにより、レバーをばね力に抗して回動させ、フック部を係合穴から離脱させる。   This lock mechanism is provided with an engagement hole in the rotation end surface of the screen portion, while supporting the lever on the in-vehicle information device main body so as to be rotatable, and a spring so that the hook portion enters the engagement hole in the lever. The structure is such that a force is applied, and the screen hook is held (locked) in a retracted state by engaging the hook portion of the lever with the engagement hole. When opening the screen part, the lever is rotated against the spring force by a button provided on the in-vehicle information device main body side, and the hook part is detached from the engagement hole.

レバーにばね力を付与する構造としては、レバーと一体の回転軸を車載情報機器本体側に回動可能に支持し、この回転軸にねじりコイルばねの巻部を嵌め込み、ねじりコイルばねの一方の腕部を車載情報機器本体側のばね受け部に係合させると共に、ねじりコイルばねの他方の腕部をレバーに設けたばね受け部に係合させる構造が採用されている。類似の構成のものとしては、コネクタの操作レバーに係るものであるが特許文献１に記載のものがある。   As a structure for applying a spring force to the lever, a rotating shaft integral with the lever is rotatably supported on the in-vehicle information device main body side, and a winding portion of a torsion coil spring is fitted on this rotating shaft, and one of the torsion coil springs is fitted. A structure is employed in which the arm portion is engaged with the spring receiving portion on the in-vehicle information device main body side, and the other arm portion of the torsion coil spring is engaged with the spring receiving portion provided on the lever. A similar configuration relates to an operation lever of a connector, but is disclosed in Patent Document 1.

しかし、上述のような構造のばねの保持機構では、レバーの回転軸にばねを取り付ける構造であるため、ばねの反力が常にレバーの回転軸に作用してしまい、組立後にレバーの回転中心軸が変形し、組立後のレバーの先端の寸法精度がでないおそれがあった。また、常にばねの反力が加わっているため、回転軸が経時変形するおそれもあった。   However, in the spring holding mechanism having the above-described structure, the spring is attached to the rotating shaft of the lever. Therefore, the reaction force of the spring always acts on the rotating shaft of the lever. May be deformed and the dimensional accuracy of the end of the lever after assembly may not be achieved. In addition, since the reaction force of the spring is always applied, the rotating shaft may be deformed with time.

この発明は、このような技術的状況にかんがみ、組立時にレバーの回転中心軸に変形を来たすことがなく、回転中心を維持することができ、しかも回転軸がばね力により経年変形することもないばね保持構造を提供することを目的してなされたものである。   In view of such a technical situation, the present invention does not cause deformation of the rotation center axis of the lever at the time of assembly, can maintain the rotation center, and the rotation axis does not deform over time due to the spring force. The object is to provide a spring holding structure.

この発明は、機器本体と、この機器本体に対し回動可能に支持されたスクリーン部とを備え、前記スクリーン部を前記機器本体に収納したときに、前記スクリーン部の回動端の端面に設けられた係合穴に、前記機器本体側に回動可能に支持させたレバーの先端を係合させるばね力を付与するねじりコイルばねを保持する構造であって、前記機器本体側に、前記レバーの回転軸と回転中心が一致するように別にばね保持軸を設け、このばね保持軸にねじりコイルばねの巻部を嵌め込み、前記ねじりコイルばねの一方の腕部を前記機器本体側に係合させると共に、前記ねじりコイルばねのもう一方の腕部を前記レバーに係合させた構成である。   The present invention includes a device main body and a screen portion that is rotatably supported with respect to the device main body, and is provided on an end surface of the rotation end of the screen portion when the screen portion is stored in the device main body. A torsion coil spring that applies a spring force to engage a tip of a lever that is rotatably supported on the device body side in the formed engagement hole, and the lever on the device body side. A spring holding shaft is separately provided so that the rotation axis of the coil and the rotation center coincide with each other, and a winding portion of the torsion coil spring is fitted into the spring holding shaft, and one arm portion of the torsion coil spring is engaged with the device main body side. In addition, the other arm portion of the torsion coil spring is engaged with the lever.

この発明に係るばね保持構造によれば、レバーの回転軸とばね保持軸とが別部材であるので、ねじりコイルばねの力がレバーの回転軸にかかることがなくなり、組立時にレバーの回転中心軸に変形を来たすことがなく、回転中心を維持することができ、しかも回転軸がねじりコイルばね力により経年変形することもない。レバーの回転軸とばね保持軸とが同軸であるので、レバーのスムーズな回転が確保できる。   According to the spring holding structure according to the present invention, since the rotating shaft of the lever and the spring holding shaft are separate members, the force of the torsion coil spring is not applied to the rotating shaft of the lever. Therefore, the center of rotation can be maintained, and the rotating shaft does not deform over time due to the torsion coil spring force. Since the rotation shaft of the lever and the spring holding shaft are coaxial, smooth rotation of the lever can be ensured.
