本発明の実施例を具体的に説明する前に、基礎となった知見を説明する。本発明の実施例は、車両に搭載された電子機器、例えば、カーオーディオ装置に関する。電子機器には、ＵＳＢ（Ｕｎｉｖｅｒｓａｌ Ｓｅｒｉａｌ Ｂｕｓ）のインターフェイス、例えばコネクタが備えられており、ＵＳＢプラグを挿入可能である。その結果、ＵＳＢを介して、電子機器は、外部の機器と接続される。ＵＳＢプラグが挿入されていない場合、ＵＳＢコネクタが露出すると、電子機器の意匠性が低下するとともに、ＵＳＢコネクタへのホコリ等の侵入による故障の発生可能性が増加する。   Prior to specific description of the embodiments of the present invention, the underlying knowledge will be described. Embodiments described herein relate generally to an electronic device mounted on a vehicle, for example, a car audio device. The electronic device is provided with a USB (Universal Serial Bus) interface, for example, a connector, into which a USB plug can be inserted. As a result, the electronic device is connected to an external device via the USB. If the USB plug is not inserted and the USB connector is exposed, the design of the electronic device is degraded, and the possibility of failure due to entry of dust or the like into the USB connector is increased.

これに対応するために、電子機器には、蓋開閉装置が備えられ、蓋部を開けた場合にＵＳＢコネクタが露出し、蓋部を閉めた場合にＵＳＢコネクタが隠れる。前述のごとく、蓋部を開閉するために、蓋部に突起状の回転軸が設けられる場合、当該回転軸は、耐衝撃性に弱いので、破損しやすい。そのため、蓋開閉装置の耐衝撃性を強化し、破損しにくくすることによって、蓋開閉装置の耐久性を向上させることが望まれる。そこで、本実施例に係る電子機器、特に電子機器に備えられた蓋開閉装置は以下のように構成される。   To cope with this, the electronic device is provided with a lid opening / closing device, and the USB connector is exposed when the lid is opened, and the USB connector is hidden when the lid is closed. As described above, when the lid is provided with a projecting rotary shaft for opening and closing the lid, the rotary shaft is easily damaged because it is weak in impact resistance. Therefore, it is desired to improve the durability of the lid opening / closing device by enhancing the impact resistance of the lid opening / closing device and making it difficult to break. Therefore, the electronic device according to the present embodiment, in particular, the lid opening / closing device provided in the electronic device is configured as follows.

図１は、本発明の実施例に係る電子機器１０が搭載される車室内を後方から見た外観図である。ここで、図１に示すように、ｘ軸、ｙ軸、ｚ軸からなる直角座標系が規定される。ｘ軸は、車両の前後方向に延び、ｙ軸は、車両の左右方向に延び、ｚ軸は、車両の上下方向に延びる。また、ｘ軸、ｙ軸、ｚ軸のそれぞれの正の方向は、図１における矢印の方向に規定され、負の方向は、矢印と逆向きの方向に規定される。以下では、ｘ軸の正方向側を「表面側」ということもあり、ｘ軸の負方向側を「裏面側」ということもある。また、ｚ軸の正方向側を「上面側」といい、ｚ軸の負方向側を「下面側」ということもある。   FIG. 1 is an external view of a vehicle interior in which an electronic device 10 according to an embodiment of the present invention is mounted as viewed from the rear.

The first support portion 24 includes a first inner peripheral wall 42, a second inner peripheral wall 44, a frame portion 58, and a hole portion 60. The second support portion 26 includes a first outer peripheral wall 46, a second outer peripheral wall 48, a base portion 62, and a hole portion 64.

蓋板３０は、ｙ軸方向に長い矩形状を有した板である。蓋板３０のｙ軸方向の両端部分のそれぞれには、側面板３２が設けられる。１組の側面板３２は、蓋板３０の一面側から同一方向に向けて立設される。   The lid plate 30 is a plate having a rectangular shape that is long in the y-axis direction. Side plates 32 are provided at both end portions of the lid plate 30 in the y-axis direction. One set of side plates 32 is erected from the one surface side of the cover plate 30 in the same direction.

各側面板３２において、蓋板３０の両端部分を結ぶｙ軸の方向において、蓋部２２の外側に向かって第１リブ部３４が立設される。外側とは、ｙ軸方向の負方向側に配置された側面板３２に対して、ｙ軸方向の負方向側を示し、ｙ軸方向の正方向側に配置された側面板３２に対して、ｙ軸方向の正方向側を示す。第１リブ部３４は、ｚ−ｘ平面において、一部分が円弧状の形状を有する。一部分は、第１内周面５０と第１外周面５２であるが、これらは完全に相対しておらず、円周の方向においてずれた位置関係を有する。   In each side plate 32, a first rib portion 34 is erected toward the outside of the lid portion 22 in the y-axis direction connecting both end portions of the lid plate 30. The outside refers to the negative direction side in the y-axis direction with respect to the side plate 32 arranged on the negative direction side in the y-axis direction, and with respect to the side plate 32 arranged on the positive direction side in the y-axis direction, The positive direction side in the y-axis direction is shown. A portion of the first rib portion 34 has an arc shape in the zx plane. A part is the first inner peripheral surface 50 and the first outer peripheral surface 52, but they are not completely opposed to each other and have a positional relationship shifted in the circumferential direction.

また、側面板３２において、第１リブ部３４と同じ方向に向かって、第２リブ部３６が立設される。第２リブ部３６は、第１リブ部３４の最も外側に配置された外側面６６を基点としてさらに外側を向く。このように、第２リブ部３６と第１リブ部３４は、ｙ軸の方向において、異なった位置に配置される。第２リブ部３６は、ｚ−ｘ平面において、円弧状の形状を有する。ここで、円弧状は、第２内周面５４と第２外周面５６とによって形成されるが、これらは相対する。第２リブ部３６の円弧による回転中心は、第１リブ部３４の円弧による回転中心とは異なった位置に配置される。これらの回転中心については後述する。   In the side plate 32, the second rib portion 36 is erected in the same direction as the first rib portion 34. The second rib portion 36 faces further outward with the outer surface 66 disposed on the outermost side of the first rib portion 34 as a base point. Thus, the 2nd rib part 36 and the 1st rib part 34 are arrange | positioned in a different position in the direction of the y-axis. The second rib portion 36 has an arc shape in the zx plane. Here, the arc shape is formed by the second inner peripheral surface 54 and the second outer peripheral surface 56, which are opposed to each other. The rotation center of the second rib portion 36 by the arc is arranged at a position different from the rotation center of the first rib portion 34 by the arc. These rotation centers will be described later.

図４は、蓋部２２の構成を示す正面図である。図４は、図２、図３に示された蓋部２２をｚ軸の正方向側、つまり上面側から見た図である。前述のごとく、ｙ軸方向に延びた蓋板３０が配置され、それのｙ軸方向の両端部分のそれぞれに第１リブ部３４が配置される。さらに、ｙ軸の負方向側の第１リブ部３４に対して、ｙ軸の負方向側に第２リブ部３６が配置されるとともに、ｙ軸の正方向側の第１リブ部３４に対しても、ｙ軸の正方向側に第２リブ部３６が配置される。なお、図２から図４における蓋部２２は、蓋開閉装置２０において開かれた状態である。蓋開閉装置２０において、蓋部２２が閉じた状態である場合、図４は、蓋部２２をｘ軸の正方向側、つまり表面側から見た図に相当する。図２、図３に戻る。   FIG. 4 is a front view showing the configuration of the lid portion 22. FIG. 4 is a view of the lid portion 22 shown in FIGS. 2 and 3 as viewed from the positive direction side of the z axis, that is, from the upper surface side.

As shown in FIG. 5A, the hole portion 60 formed in the frame portion 58 is closed by the lid plate 30. In FIG. 5 (d), the first groove 38 is formed between the first inner peripheral wall 42 and the first outer peripheral wall 46. The first groove portion 38 can slide on the first rib portion 34. In the closed state, a part of the first inner peripheral surface 50 of the first rib portion 34 and a part of the first inner peripheral wall 42 face each other, and the first outer peripheral surface 52 of the first rib portion 34 and the first outer peripheral surface A part of the wall 46 faces. In FIG. 5G, the second groove portion 40 is formed between the second inner peripheral wall 44 and the second outer peripheral wall 48. The second groove part 40 can slide on the second rib part 36. In the closed state, the second rib portion 36 is not fitted into the second groove portion 40 and is detached from the second groove portion 40.

図６（ａ）−（ｂ）は、蓋開閉装置２０における蓋板３０の回転中心を示す断面図である。ここでは、図６（ａ）を説明に使用する。図６（ａ）では、回転中心を明瞭にするために、蓋板３０と枠部５８とを示す。図６（ａ）において「Ｃ」と示された蓋板３０が、前述の閉状態に相当する。   FIGS. 6A and 6B are cross-sectional views showing the rotation center of the lid plate 30 in the lid opening / closing device 20. Here, FIG. 6A is used for explanation. FIG. 6A shows the cover plate 30 and the frame portion 58 in order to clarify the rotation center. The lid plate 30 indicated as “C” in FIG. 6A corresponds to the above-described closed state.

次に、切替状態を説明する。図５（ｂ）のように、枠部５８に形成された孔部６０は、蓋板３０によってほぼ塞がれている。図５（ｅ）において、第１リブ部３４は、図５（ｄ）よりもｚ軸の負方向に第１溝部３８を摺動する。具体的には、第１リブ部３４の第１内周面５０のポイント「Ｐ１」が第１内周壁４２に近づく位置まで、第１リブ部３４が第１内周壁４２に沿って移動する。また、第１リブ部３４の第１外周面５２は、第１外周壁４６に沿って移動する。図５（ｈ）において、第２外周面５６の一部、つまり第２外周面５６の下端部分からポイント「Ｐ２」までの部分が第２溝部４０に観入される。その際、第２リブ部３６の第２内周面５４の一部と、第２内周壁４４の一部とが対向し、第２リブ部３６の第２外周面５６の一部と、第２外周壁４８の一部とが対向する。   Next, the switching state will be described. As shown in FIG. 5B, the hole 60 formed in the frame portion 58 is almost closed by the lid plate 30. In FIG.5 (e), the 1st rib part 34 slides the 1st groove part 38 to the negative direction of az axis rather than FIG.5 (d). Specifically, the first rib portion 34 moves along the first inner peripheral wall 42 until the point “P1” of the first inner peripheral surface 50 of the first rib portion 34 approaches the first inner peripheral wall 42. Further, the first outer peripheral surface 52 of the first rib portion 34 moves along the first outer peripheral wall 46. In FIG. 5H, a part of the second outer peripheral surface 56, that is, a portion from the lower end portion of the second outer peripheral surface 56 to the point “P2” is viewed in the second groove portion 40. At that time, a part of the second inner peripheral surface 54 of the second rib portion 36 and a part of the second inner peripheral wall 44 face each other, a part of the second outer peripheral surface 56 of the second rib portion 36, 2 A part of outer peripheral wall 48 opposes.

図６（ａ）において「Ｓ」と示された蓋板３０が、前述の切替状態に相当する。閉状態から切替状態に遷移する回転は、「Ｃ」から「Ｓ」に遷移する回転に相当し、その回転中心は「Ｒ１」と示され、回転の軌跡は「Ｃ１」と示される。この回転は、第１リブ部３４と第１溝部３８とによってなされており、第２リブ部３６と第２溝部４０とによってなされていない。そのため、第１リブ部３４および第１溝部３８の回転中心が「Ｒ１」に相当する。   The lid plate 30 indicated as “S” in FIG. 6A corresponds to the switching state described above. The rotation that transitions from the closed state to the switching state corresponds to the rotation that transitions from “C” to “S”, the center of rotation is indicated as “R1”, and the locus of rotation is indicated as “C1”. This rotation is made by the first rib portion 34 and the first groove portion 38, and is not made by the second rib portion 36 and the second groove portion 40. Therefore, the rotation centers of the first rib portion 34 and the first groove portion 38 correspond to “R1”.

最後に、開状態を説明する。図５（ｃ）のように、枠部５８に形成された孔部６０から、基部６２、孔部６４が露出される。そのため、孔部６４内に設けられたＵＳＢコネクタ（図示せず）も露出される。図５（ｆ）において、第１リブ部３４の第１内周面５０は、第１内周壁４２に沿って移動するが、第１リブ部３４の第１外周面５２は、第１外周壁４６から離れて移動する。図５（ｉ）において、第２リブ部３６は、図５（ｈ）よりもｚ軸の負方向に第２溝部４０を摺動する。具体的には、第２リブ部３６の第２内周面５４は、第２内周壁４４に沿って移動し、第２リブ部３６の第２外周面５６は、第２外周壁４８に沿って移動する。   Finally, the open state will be described. As shown in FIG. 5C, the base 62 and the hole 64 are exposed from the hole 60 formed in the frame 58. Therefore, the USB connector (not shown) provided in the hole 64 is also exposed. In FIG. 5 (f), the first inner peripheral surface 50 of the first rib portion 34 moves along the first inner peripheral wall 42, but the first outer peripheral surface 52 of the first rib portion 34 is the first outer peripheral wall. Move away from 46. In FIG. 5I, the second rib portion 36 slides in the second groove portion 40 in the negative direction of the z axis as compared with FIG. Specifically, the second inner peripheral surface 54 of the second rib portion 36 moves along the second inner peripheral wall 44, and the second outer peripheral surface 56 of the second rib portion 36 extends along the second outer peripheral wall 48. Move.

図６（ａ）において「Ｏ」と示された蓋板３０が、前述の開状態に相当する。切替状態から開状態に遷移する回転は、「Ｓ」から「Ｏ」に遷移する回転に相当し、その回転中心は「Ｒ２」と示され、回転の軌跡は「Ｃ２」と示される。この回転は、第２リブ部３６と第２溝部４０とによってなされており、第１リブ部３４と第１溝部３８とによってなされていない。そのため、第２リブ部３６および第２溝部４０の回転中心が「Ｒ２」に相当する。   The lid plate 30 indicated as “O” in FIG. 6A corresponds to the open state described above. The rotation that transitions from the switching state to the open state corresponds to the rotation that transitions from “S” to “O”, the rotation center thereof is indicated as “R2”, and the locus of the rotation is indicated as “C2”. This rotation is made by the second rib portion 36 and the second groove portion 40, and is not made by the first rib portion 34 and the first groove portion 38. Therefore, the rotation centers of the second rib portion 36 and the second groove portion 40 correspond to “R2”.

このように蓋開閉装置２０は、２つの回転中心を切りかえながら、蓋部２２を開閉させる。ここでは、２つの回転中心を切りかえることによる効果を、比較対象を使用しながら説明する。図６（ｂ）は、蓋開閉装置２０の比較対象における蓋板２３０の回転中心を示す断面図である。蓋板２３０は蓋板３０に対応し、枠部２５８は枠部５８に対応し、孔部２６０は孔部６０に対応する。図６（ｂ）において「Ｃ」と示された蓋板２３０が、閉状態に相当する。「Ｃ」における枠部２５８と蓋板２３０との位置関係は、図６（ａ）の「Ｃ」における枠部５８と蓋板３０との位置関係と同一である。また、比較対象においては、回転中心「Ｒ２」のみが配置される。   Thus, the lid opening / closing device 20 opens and closes the lid 22 while switching between the two rotation centers. Here, the effect of switching between the two rotation centers will be described using a comparison target. FIG. 6B is a cross-sectional view showing the rotation center of the lid plate 230 as a comparison target of the lid opening / closing device 20. The lid plate 230 corresponds to the lid plate 30, the frame portion 258 corresponds to the frame portion 58, and the hole portion 260 corresponds to the hole portion 60. The lid plate 230 indicated as “C” in FIG. 6B corresponds to the closed state. The positional relationship between the frame portion 258 and the lid plate 230 at “C” is the same as the positional relationship between the frame portion 58 and the lid plate 30 at “C” in FIG. Further, only the rotation center “R2” is arranged in the comparison target.

回転中心「Ｒ２」による回転の軌跡は「Ｃ２」と示される。図示のごとく、ポイント「Ｐ３」において、蓋板２３０と枠部２５８とが接触する。そのため、図６（ｂ）の構成では、蓋板２３０を開閉できない。図６（ｂ）において、蓋板２３０を開閉可能にするためには、ポイント「Ｐ３」における接触を回避するために、ｚ軸の正方向側の枠部２５８をさらにｚ軸の正方向側に配置させる必要がある。そのため、孔部２６０がｚ方向に広がる。これにより、閉状態においても、蓋板２３０によって塞がれない孔部２６０の部分が大きくなり、意匠性が低下する。つまり、２つの回転中心を切りかえながら、蓋部２２を開閉させることによって、意匠性が向上する。   The locus of rotation by the rotation center “R2” is indicated as “C2”. As illustrated, at the point “P3”, the lid plate 230 and the frame portion 258 come into contact with each other. Therefore, in the configuration of FIG. 6B, the lid plate 230 cannot be opened and closed. In FIG. 6B, in order to allow the lid plate 230 to be opened and closed, in order to avoid contact at the point “P3”, the frame portion 258 on the positive direction side of the z axis is further moved to the positive direction side of the z axis. Must be placed. Therefore, the hole 260 is expanded in the z direction. As a result, even in the closed state, the portion of the hole 260 that is not blocked by the lid plate 230 becomes large, and the design is deteriorated. In other words, the design is improved by opening and closing the lid 22 while switching between the two rotation centers.

図７は、電子機器１０の構成を示す。電子機器１０は、処理部１００、モニタ１４、スピーカ１２、操作部１０２、接続部１０４を含む。また、電子機器１０は、図１にも示したように蓋開閉装置２０を含む。   FIG. 7 shows the configuration of the electronic device 10. The electronic device 10 includes a processing unit 100, a monitor 14, a speaker 12, an operation unit 102, and a connection unit 104. Moreover, the electronic device 10 includes a lid opening / closing device 20 as shown in FIG.

処理部１００は、所定の処理を実行する。前述のごとく、電子機器１０がカーオーディオ装置である場合、所定の処理は、音声再生、情報生成等に相当する。スピーカ１２、モニタ１４は、図１に示すように配置される。スピーカ１２は、処理部１００において再生された音声を出力する。また、モニタ１４は、処理部１００において生成された情報を表示する。   The processing unit 100 executes a predetermined process. As described above, when the electronic device 10 is a car audio device, the predetermined processing corresponds to sound reproduction, information generation, and the like. The speaker 12 and the monitor 14 are arranged as shown in FIG. The speaker 12 outputs the sound reproduced by the processing unit 100. The monitor 14 displays information generated in the processing unit 100.

操作部１０２は、ボタン等によって構成されており、ユーザによる指示を受けつける。指示の一例は、処理部１００において再生すべき音声の選択の指示である。操作部１０２は、受けつけた指示を処理部１００に出力する。なお、電子機器１０にタッチパネルが搭載される場合、モニタ１４と操作部１０２とが一体的に構成される。   The operation unit 102 includes buttons and receives instructions from the user. An example of the instruction is an instruction for selecting a sound to be reproduced in the processing unit 100. The operation unit 102 outputs the received instruction to the processing unit 100. When the electronic device 10 is equipped with a touch panel, the monitor 14 and the operation unit 102 are integrally configured.

接続部１０４は、蓋開閉装置２０に設けられた孔部６４（図示せず）の中に配置される。接続部１０４は、前述のＵＳＢコネクタに相当する。接続部１０４は、蓋開閉装置２０における蓋部２２が開いた場合に、ＵＳＢプラグを備えた外部の機器（図示せず）と接続が可能になる。接続部１０４を介して、処理部１００と外部の機器との間でデータが送受信される。   The connecting portion 104 is disposed in a hole 64 (not shown) provided in the lid opening / closing device 20. The connection unit 104 corresponds to the USB connector described above. The connection unit 104 can be connected to an external device (not shown) provided with a USB plug when the lid 22 in the lid opening / closing device 20 is opened. Data is transmitted and received between the processing unit 100 and an external device via the connection unit 104.

この構成は、ハードウエア的には、任意のコンピュータのＣＰＵ、メモリ、その他のＬＳＩで実現でき、ソフトウエア的にはメモリにロードされたプログラムなどによって実現されるが、ここではそれらの連携によって実現される機能ブロックを描いている。したがって、これらの機能ブロックがハードウエアのみ、ハードウエアとソフトウエアの組合せによっていろいろな形で実現できることは、当業者には理解されるところである。   This configuration can be realized in terms of hardware by a CPU, memory, or other LSI of any computer, and in terms of software, it can be realized by a program loaded in the memory, but here it is realized by their cooperation. Draw functional blocks. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms only by hardware, or by a combination of hardware and software.

本発明の実施例によれば、突起した回転軸ではなく、円弧状のリブと溝部によって蓋部を開閉させるので、蓋開閉装置の耐衝撃性を強化し、破損しにくくできる。また、蓋開閉装置の耐衝撃性が強化されて、破損しにくくなるので、蓋開閉装置の耐久性を向上できる。また、２つの回転中心を切りかえながら、蓋部を開閉させるので、開閉時の蓋部の軌跡の範囲を小さくできる。また、開閉時の蓋部の軌跡の範囲が小さくなるので、第１支持部に設けられた枠部と蓋板との間の隙間を小さくできる。   According to the embodiment of the present invention, since the lid portion is opened and closed by the arc-shaped rib and groove instead of the protruding rotating shaft, the impact resistance of the lid opening and closing device can be enhanced and it is difficult to break. In addition, since the impact resistance of the lid opening / closing device is enhanced and the lid opening / closing device is not easily damaged, the durability of the lid opening / closing device can be improved. Further, since the lid is opened and closed while switching between the two rotation centers, the range of the locus of the lid during opening and closing can be reduced. Moreover, since the range of the locus of the lid at the time of opening and closing is reduced, the gap between the frame provided on the first support portion and the lid plate can be reduced.

また、第１支持部に設けられた枠部と蓋板との間の隙間が小さくなるので、意匠性を向上できる。また、開閉時の蓋部の軌跡の範囲が小さくなるので、蓋開閉装置を小型化できる。また、蓋板の両端部分を結ぶ方向において、第１リブ部と第２リブ部とを異なった位置に配置させるので、２つの回転中心を切りかえる構成を簡易に実現できる。また、第１支持部と第２支持部とによって、蓋部を挟む構成であるので、組み立てを簡易にできる。   Moreover, since the clearance gap between the frame part provided in the 1st support part and a cover board becomes small, designability can be improved. In addition, since the range of the locus of the lid at the time of opening / closing becomes small, the lid opening / closing device can be miniaturized. Further, since the first rib portion and the second rib portion are arranged at different positions in the direction connecting the both end portions of the cover plate, a configuration in which the two rotation centers are switched can be easily realized. Moreover, since it is the structure which pinches | interposes a cover part with a 1st support part and a 2nd support part, an assembly can be simplified.
