Description

本発明は、モータを該モータによって駆動される被駆動要素を有する機器の筐体に取り付けるための構造に関し、特にモータの振動が筐体に伝達されるのを可及的に防止し、且つモータを正確に位置決めして筐体に取り付ける制振取付構造に関する。   The present invention relates to a structure for attaching a motor to a housing of a device having a driven element driven by the motor, and in particular, prevents vibration of the motor from being transmitted to the housing as much as possible, and the motor. The present invention relates to a vibration damping mounting structure that accurately positions and attaches to a housing.

従来、モータを内蔵して構成された光学機器や電子機器がある。これらの機器では、モータが駆動することによって振動が伝達すると種々の弊害が生ずる。例えば、ズーミング動作やフォーカシング動作を行うために駆動モータをカメラ本体内に配設し、動画撮影や録音などの機能を備えたデジタルカメラでは、モータの振動によって、動画撮影の精度を損なったり不要な雑音が録音されたりするおそれがある。また、モータの振動によって、デジタルカメラに備えた電子回路に障害が生ずる虞もある。   Conventionally, there are optical devices and electronic devices configured with a built-in motor. In these devices, various vibrations occur when vibration is transmitted by driving the motor. For example, in a digital camera equipped with a drive motor in the camera body to perform zooming and focusing operations and equipped with functions such as movie shooting and recording, the accuracy of movie shooting is lost or unnecessary due to the vibration of the motor. Noise may be recorded. In addition, there is a possibility that the electronic circuit provided in the digital camera may be damaged by the vibration of the motor.

そこで、モータの振動が機器の筐体に伝達されるのを可及的に防止するために、モータが取り付けられたブラケットに複数の貫通孔を形成し、これらの貫通孔に弾性材料からなる制振ブッシュをそれぞれ装着し、ブラケット表面からこれら複数の制振ブッシュに挿通した固定ねじを機器筐体に形成された固定雌ねじ孔に螺合させる制振取付構造が提案されている（特許文献１、実用新案文献１）。   Therefore, in order to prevent the vibration of the motor from being transmitted to the housing of the device as much as possible, a plurality of through holes are formed in the bracket to which the motor is attached, and the through holes are made of an elastic material. There has been proposed a vibration damping mounting structure in which a vibration bush is mounted, and a fixing screw inserted through the plurality of vibration suppression bushes from the bracket surface is screwed into a fixed female screw hole formed in the device housing (Patent Document 1, Utility model literature 1).

しかしこれらの制振取付構造では、固定ねじと制振ブッシュ（ブラケットと筐体）が該制振ブッシュの弾性変形範囲で相対移動できる。このため、モータを固定したブラケット（すなわちモータ）を機器筐体上に正確に位置決めして固定することが困難であった。別言すると、ブラケット上のモータと、該モータによって駆動される被駆動機器とを精密に位置決めして固定しなければならない用途にこれら従来構造を用いることはできなかった。   However, in these vibration damping mounting structures, the fixing screw and the vibration damping bush (bracket and casing) can be relatively moved within the elastic deformation range of the vibration damping bush. For this reason, it has been difficult to accurately position and fix the bracket (that is, the motor) to which the motor is fixed on the device housing. In other words, these conventional structures cannot be used in applications where the motor on the bracket and the driven device driven by the motor must be precisely positioned and fixed.

そこで、本発明は、モータを高精度で機器筐体に取り付けることができ、制振も図れるモータの制振取付構造を提供することを目的とする。   SUMMARY OF THE INVENTION An object of the present invention is to provide a vibration damping mounting structure for a motor that can attach a motor to a device casing with high accuracy and can also control vibration.

本発明は、モータが取り付けられたブラケット；該ブラケット上のモータによって駆動される被駆動要素を有する機器の筐体；上記ブラケットに形成された複数の貫通孔；これらの貫通孔にそれぞれ装着された弾性材料からなる複数の制振ブッシュ；及び上記ブラケット表面からこれら複数の制振ブッシュにそれぞれ挿通され、上記機器筐体に形成された固定雌ねじ孔に螺合される固定ねじ；を有するモータの制振取付構造において、上記機器筐体に、上記固定雌ねじ孔と同軸に位置決め円筒状凹部を設け、上記固定ねじに、上記位置決め円筒状凹部に挿入され、該位置決め円筒状凹部に当接する位置決め軸部を形成したことを特徴としている。   The present invention relates to a bracket to which a motor is attached; a housing of a device having a driven element driven by the motor on the bracket; a plurality of through holes formed in the bracket; A plurality of vibration control bushes made of an elastic material; and a fixing screw that is inserted into each of the plurality of vibration suppression bushes from the bracket surface and is screwed into a fixed female screw hole formed in the device housing. In the vibration mounting structure, a positioning cylindrical recess is provided in the device casing coaxially with the fixed female screw hole, and the fixing screw is inserted into the positioning cylindrical recess, and the positioning shaft is in contact with the positioning cylindrical recess. It is characterized by having formed.

複数の固定ねじの位置決め軸部と対応する位置決め円筒状凹部に対する嵌合精度は、場所によって互いに異ならせるのがよい。   The fitting accuracy with respect to the positioning cylindrical recesses corresponding to the positioning shafts of the plurality of fixing screws may be different from each other depending on the location.

位置決め円筒状凹部の内径は、固定雌ねじ孔の径より大径とし、該円筒状凹部の底部と雌ねじ部の段部に、位置決め軸部を当接させるのがよい。   The inner diameter of the positioning cylindrical recess is preferably larger than the diameter of the fixed female screw hole, and the positioning shaft is preferably brought into contact with the bottom of the cylindrical recess and the stepped portion of the female screw.

複数の制振ブッシュの１つには、該制振ブッシュより硬質な材料からなり先端部に、上記位置決め円筒状凹部に嵌合される位置決め凸部を有するリテーナブッシュを挿通し、上記ブラケット表面から該リテーナブッシュ内に挿通した固定ねじを上記機器筐体の固定雌ねじ孔に螺合させることができる。   One of the plurality of vibration suppression bushes is inserted with a retainer bush made of a material harder than the vibration suppression bushing and having a positioning convex portion fitted into the positioning cylindrical concave portion at the tip portion, and from the bracket surface. The fixing screw inserted into the retainer bush can be screwed into the fixing female screw hole of the device casing.

本発明によれば、ブラケットの貫通孔に装着された制振ブッシュの位置決めは、機器筐体に形成した位置決め円筒状凹部と、制振ブッシュ内に挿入した固定ねじの先端位置軸部との嵌合によって行われるため、制振ブッシュの貫通孔に直接固定ねじを挿入固定していた従来装置に比べ、ブラケットすなわちモータの機器筐体に対する位置決め精度を高めることができる。   According to the present invention, the damping bush mounted in the through hole of the bracket is positioned by fitting between the positioning cylindrical recess formed in the device housing and the tip position shaft portion of the fixing screw inserted into the damping bush. Therefore, the positioning accuracy of the bracket, that is, the motor relative to the device housing can be improved as compared with the conventional device in which the fixing screw is directly inserted and fixed in the through hole of the damping bush.

図１ないし図５は、本発明のモータの制振取付構造をデジタルカメラ１に適用した第一の実施形態を示している。このデジタルカメラ１は、レンズ２（図２、図３）を保持したレンズ枠３を光軸Ｘ方向に移動させるためのモータ４がブラケット５上に固定されており、このブラケット５が固定ねじ６によって機器筐体（カメラボディ）９に取り付けられている。   FIG. 1 to FIG. 5 show a first embodiment in which the motor vibration damping mounting structure of the present invention is applied to a digital camera 1. In this digital camera 1, a motor 4 for moving a lens frame 3 holding a lens 2 (FIGS. 2 and 3) in the direction of the optical axis X is fixed on a bracket 5, and the bracket 5 is a fixing screw 6. Is attached to a device housing (camera body) 9.

レンズ枠３は、筐体９に固定されたガイド軸１０を含むガイド機構により回転を拘束されて光軸方向にスライド自在に案内されている。レンズ枠３には実質的に一体にラック体１１が設けられており、このラック体１１がモータ４に接続されたリードスクリュー１２に噛み合っていて、リードスクリュー１２の回転がレンズ枠３の直進運動に変換される。このような直進案内機構は周知である。   The lens frame 3 is guided to be slidable in the optical axis direction by being restricted in rotation by a guide mechanism including a guide shaft 10 fixed to the housing 9. A rack body 11 is provided substantially integrally with the lens frame 3, and the rack body 11 meshes with a lead screw 12 connected to the motor 4, and the rotation of the lead screw 12 causes the lens frame 3 to move linearly. Is converted to Such a straight guide mechanism is well known.

リードスクリュー１２は、図１に示すように、基端部側がモータ４の回転軸に結合され、先端部側がブラケット５の側壁５ｂに回転自在に支持されている。図２に示すように、モータ４の上面には、このモータ４の電源端子４ａに接続され、その駆動を制御するための電子回路が備えられたフレキシブルプリント基板１３が搭載されている。   As shown in FIG. 1, the lead screw 12 is coupled to the rotating shaft of the motor 4 on the base end side and is rotatably supported on the side wall 5 b of the bracket 5 on the tip end side. As shown in FIG. 2, on the upper surface of the motor 4, there is mounted a flexible printed circuit board 13 that is connected to a power supply terminal 4a of the motor 4 and is equipped with an electronic circuit for controlling the driving thereof.

モータ４は、金属材料からなるブラケット５上に予め位置決め固定されている。このブラケット５は、図１に示す３カ所の取付部Ｐ１、Ｐ２、Ｐ３において、筐体９に固定される。ブラケット５には、この３カ所の取付部Ｐ１、Ｐ２、Ｐ３に対応させて３個の貫通孔５ａ（図３、図４）が形成されている。   The motor 4 is positioned and fixed in advance on a bracket 5 made of a metal material. The bracket 5 is fixed to the housing 9 at the three attachment portions P1, P2, and P3 shown in FIG. In the bracket 5, three through holes 5a (FIGS. 3 and 4) are formed so as to correspond to the three attachment portions P1, P2, and P3.

筐体９には、３ケ所の取付部Ｐ１、Ｐ２、Ｐ３に対応させて、表面側から順に、位置決め凹部９ａと、固定ねじ６の雄ねじ部６ｂが螺合する固定雌ねじ孔９ｂとが形成されている。そして、これらの３カ所の取付部のうち、２カ所の取付部Ｐ１とＰ２の位置決め凹部９ａは、図５に示すように、断面円形をなし、かつ取付部Ｐ２の位置決め凹部９ａの径Ｄ１（図３）の方が取付部Ｐ１の位置決め凹部９ａの径Ｄ２（同）より大きい。これに対し、取付部Ｐ３の位置決め凹部９ａは、ストレート状の両辺の両端を円弧で連結した非円形の内壁形状を有する（図５）。   The housing 9 is formed with a positioning concave portion 9a and a fixed female screw hole 9b into which the male screw portion 6b of the fixing screw 6 is screwed in order from the surface side, corresponding to the three mounting portions P1, P2, and P3. ing. Of these three mounting portions, the positioning recesses 9a of the two mounting portions P1 and P2 have a circular cross section as shown in FIG. 5 and have a diameter D1 of the positioning recess 9a of the mounting portion P2 ( 3) is larger than the diameter D2 (same as above) of the positioning recess 9a of the mounting portion P1. On the other hand, the positioning recess 9a of the mounting portion P3 has a non-circular inner wall shape in which both ends of both straight sides are connected by an arc (FIG. 5).

ブラケット５には、これらの３カ所の取付部Ｐ１、Ｐ２、Ｐ３の３個の貫通孔５ａに共通に、弾性材料からなる筒状の制振ブッシュ（ゴムブッシュ）２３が装着されている。   A cylindrical damping bush (rubber bush) 23 made of an elastic material is attached to the bracket 5 in common with the three through holes 5a of these three attachment portions P1, P2, and P3.

例えばゴム材料のような制振（吸振、除振）作用を有する材料からなる筒状の制振ブッシュ２３は、軸部に貫通孔２３ａを有し、その外周面に、ブラケット５の貫通孔５ａの内周に係合する環状溝２３ｂと、この環状溝２３ｂの上下に位置する一対のフランジ２３ｃ、２３ｄとを有している。この筒状ブッシュ２３は、別体を後にブラケット５の貫通孔５ａに装着する他、アウトサート成形によって予めブラケット５に一体に形成することができる。   For example, the cylindrical vibration damping bush 23 made of a material having a vibration damping (vibration absorbing / vibrating) action such as a rubber material has a through hole 23a in the shaft portion, and the through hole 5a of the bracket 5 is formed on the outer peripheral surface thereof. An annular groove 23b that engages with the inner periphery of the annular groove 23b and a pair of flanges 23c and 23d positioned above and below the annular groove 23b. The cylindrical bush 23 can be formed integrally with the bracket 5 in advance by outsert molding in addition to mounting a separate body in the through hole 5a of the bracket 5 later.

３カ所の取付部のうち、２カ所の取付部Ｐ１とＰ２における制振取付構造２０は、図３に示すように、制振ブッシュ２３と固定ねじ６から構成されている。この取付部Ｐ１とＰ２の制振取付構造２０は、筐体９の断面円形の位置決め凹部（位置決め円筒状凹部）９ａに、固定ねじ６に形成した位置決め軸部６ｃを嵌合させている。すなわち、固定ねじ６は、頭部６ａと雄ねじ部６ｂとの間に、両者の中間径の断面円形の位置決め軸部６ｃを有している。位置決め軸部６ｃは、制振ブッシュ２３の貫通孔２３ａを弾性変形させて嵌まり、同時に位置決め凹部９ａに嵌まる。取付部Ｐ１における固定ねじ６の位置決め軸部６ｃと位置決め凹部９ａとの間のクリアランスは、取付部Ｐ２における固定ねじ６の位置決め軸部６ｃと位置決め凹部９ａとの間のクリアランスより大きい。   Of the three attachment portions, the vibration damping attachment structure 20 at the two attachment portions P1 and P2 includes a vibration damping bush 23 and a fixing screw 6 as shown in FIG. In the vibration damping mounting structure 20 of the mounting portions P1 and P2, a positioning shaft portion 6c formed on the fixing screw 6 is fitted into a positioning recess (positioning cylindrical recess) 9a having a circular cross section of the housing 9. That is, the fixing screw 6 has a positioning shaft portion 6c having a circular cross section with an intermediate diameter between the head portion 6a and the male screw portion 6b. The positioning shaft portion 6c is fitted by elastically deforming the through hole 23a of the vibration damping bush 23, and is simultaneously fitted in the positioning recess 9a. The clearance between the positioning shaft portion 6c of the fixing screw 6 and the positioning recess 9a in the mounting portion P1 is larger than the clearance between the positioning shaft portion 6c of the fixing screw 6 and the positioning recess 9a in the mounting portion P2.

これに対し、取付部Ｐ３においては、制振ブッシュ２３と固定ねじ６に加えて、リテーナブッシュ２４によって制振取付構造２０が構成されている。   On the other hand, in the attachment portion P3, in addition to the vibration suppression bush 23 and the fixing screw 6, a vibration suppression attachment structure 20 is configured by the retainer bush 24.

リテーナブッシュ２４は、合成樹脂や金属材料などの制振ブッシュ２３より十分硬質な材料からなっている。このリテーナブッシュ２４は、軸部に貫通孔２４ａを有し、外周面にフランジ２４ｂを有し、このフランジ２４ｂによって、制振ブッシュ２３の貫通孔２３ａに嵌合するブッシュ内嵌合部２４ｃと、制振ブッシュ２３から突出するブッシュ外突出部（先端位置決め凸部）２４ｄとに分けられている。ブッシュ内嵌合部２４ｃは、その外径が制振ブッシュ２３の貫通孔２３ａの内径に対して僅かに大きく形成され、貫通孔２３ａに弾性変形した状態で挿通される。   The retainer bush 24 is made of a material that is sufficiently harder than the vibration control bush 23 such as a synthetic resin or a metal material. The retainer bushing 24 has a through hole 24a in the shaft portion and a flange 24b on the outer peripheral surface, and the flange inner portion 24c fits into the through hole 23a of the damping bush 23 by the flange 24b. It is divided into a bush outer projecting portion (tip positioning projecting portion) 24 d projecting from the damping bush 23. The inside fitting portion 24c of the bush has an outer diameter that is slightly larger than the inner diameter of the through hole 23a of the damping bush 23, and is inserted into the through hole 23a in an elastically deformed state.

リテーナブッシュ２４のブッシュ外突出部２４ｄは、取付部Ｐ３の位置決め凹部９ａの形状に対応している。すなわち、取付部Ｐ３のリテーナブッシュ２４のブッシュ外突出部２４ｄは、取付部Ｐ３の位置決め凹部９ａの形状に対応させて、ストレート状の両辺の両端を円弧で連結した形状を有し、かつ図５の左右方向（ストレート状両辺と平行な方向）のクリアランスより上下方向のクリアランスの方が小さい。つまり、取付部Ｐ３においては、リテーナブッシュ２４は位置決め凹部９ａのストレート状両辺の方向に相対的に移動可能であり、この直線方向に微調整できる。   The bush outer protrusion 24d of the retainer bush 24 corresponds to the shape of the positioning recess 9a of the attachment portion P3. That is, the bush outer protrusion 24d of the retainer bush 24 of the attachment portion P3 has a shape in which both ends of the straight side are connected by an arc corresponding to the shape of the positioning recess 9a of the attachment portion P3, and FIG. The clearance in the vertical direction is smaller than the clearance in the left and right direction (direction parallel to both straight sides). That is, in the attachment portion P3, the retainer bush 24 is relatively movable in the direction of both straight sides of the positioning recess 9a and can be finely adjusted in this linear direction.

この取付部Ｐ３に用いられる固定ねじ６は、ブラケット５の貫通孔５ａの内径より十分大きい外形を有する頭部６ａと、リテーナブッシュ２４に挿通され、雌ねじ孔９ｂに螺合する雄ねじ部６ｂとを備えている。つまり、位置決め軸部６ｃを備えていない。   The fixing screw 6 used for the mounting portion P3 includes a head 6a having an outer shape sufficiently larger than the inner diameter of the through hole 5a of the bracket 5, and a male screw portion 6b inserted through the retainer bush 24 and screwed into the female screw hole 9b. I have. That is, the positioning shaft portion 6c is not provided.

以上のブラケット５を筐体９に取り付ける際には、取付部Ｐ１とＰ２では、予めブラケット５に係合された制振ブッシュ２３の筐体９とは反対側の端面に座金２６を位置させ、この座金２６及び貫通孔２３ａに、固定ねじ６の位置決め段部６ｃを嵌め、該位置決め段部６ｃを筐体９の位置決め凹部９ａの底部に当接させる。そして、固定ねじ６の雄ねじ部６ｂを、筐体９の雌ねじ孔９ｂに螺合させる。   When attaching the bracket 5 to the housing 9, the washer 26 is positioned on the end surface opposite to the housing 9 of the damping bush 23 previously engaged with the bracket 5 at the attachment portions P1 and P2. The positioning step 6c of the fixing screw 6 is fitted into the washer 26 and the through hole 23a, and the positioning step 6c is brought into contact with the bottom of the positioning recess 9a of the housing 9. Then, the male screw portion 6 b of the fixing screw 6 is screwed into the female screw hole 9 b of the housing 9.

また、取付部Ｐ３では、制振ブッシュ２３の貫通孔２３ａに、リテーナブッシュ２４のブッシュ内嵌合部２４ｃを挿通させ、次いで、ブッシュ外突出部２４ｄを筐体９に備えた位置決め凹部９ａに嵌合させ、フランジ２４ｂを筐体９の表面に当接させる。また、制振ブッシュ２３のフランジ２４ｂとは反対側の端面に座金２６を位置させ、この座金２６とリテーナブッシュ２４に固定ねじ６の雄ねじ部６ｂを挿通させ、筐体９の雌ねじ孔９ｂに螺合させる。   Further, in the attachment portion P3, the in-bush fitting portion 24c of the retainer bush 24 is inserted into the through hole 23a of the vibration suppression bush 23, and then the bush outer protrusion portion 24d is fitted into the positioning recess 9a provided in the housing 9. The flange 24b is brought into contact with the surface of the housing 9. Further, a washer 26 is positioned on the end surface of the damping bushing 23 opposite to the flange 24 b, the male screw portion 6 b of the fixing screw 6 is inserted into the washer 26 and the retainer bush 24, and screwed into the female screw hole 9 b of the housing 9. Combine.

取付部Ｐ１、Ｐ２における固定ねじ６の位置決め段部６ｃと筐体９の位置決め凹部９ａの形状（クリアランス）の差、及び取付部Ｐ３におけるリテーナブッシュ２４のブッシュ外突出部２４ｄと位置決め凹部９ａの形状（クリアランス）の差は、以上の固定作業を容易（可能）にする。そして制振ブッシュ２３（ブラケット５）の位置決めは、２つの取付部Ｐ１、Ｐ２においては、固定ねじ６の位置決め軸部６ｃと筐体９の位置決め凹部９ａとの嵌合によって行われ、取付部Ｐ３においては、リテーナブッシュ２４のブッシュ外突出部２４ｄと筐体９の位置決め凹部９ａとの嵌合によって行われるため、制振ブッシュ２３の貫通孔２３ａに直接固定ねじ６を挿入固定する場合に比し、ブラケット５（モータ４）の筐体９に対する位置決め精度を高めることができる。   Differences in the shape (clearance) of the positioning step 6c of the fixing screw 6 and the positioning recess 9a of the housing 9 in the mounting portions P1 and P2, and the shapes of the protrusions 24d outside the bush of the retainer bush 24 and the positioning recess 9a in the mounting portion P3 The difference in (clearance) makes the above fixing work easy (possible). The positioning of the damping bush 23 (bracket 5) is performed by fitting the positioning shaft 6c of the fixing screw 6 and the positioning recess 9a of the housing 9 in the two mounting portions P1 and P2, and the mounting portion P3. Is performed by fitting the protruding portion 24d outside the bush 24 of the retainer bush 24 with the positioning recess 9a of the housing 9, so that the fixing screw 6 is directly inserted into and fixed to the through hole 23a of the damping bush 23. The positioning accuracy of the bracket 5 (motor 4) with respect to the housing 9 can be increased.

以上の実施形態では、本発明をデジタルカメラのモータの制振取付構造に適用した実施形態について説明したが、本発明は、モータによって駆動される可動要素を有する機器の筐体にモータを取り付けるための構造一般に適用することができる。   In the above embodiment, the embodiment in which the present invention is applied to the vibration damping mounting structure of a digital camera motor has been described.
