Description

本発明は、無接点充電用充電台であって、特に車載用の無接点充電用充電台に関する。   The present invention relates to a charging stand for contactless charging, and more particularly to a charging stand for in-vehicle charging for contactless charging.

携帯機器、例えば携帯電話の高性能化に伴い、その電力消費が大きくなり、車両内においても充電を行えるようにすることが望まれている。   As mobile devices such as mobile phones become more sophisticated, their power consumption increases, and it is desired to be able to charge even in vehicles.

従来の無接点充電用充電台は、ケースと、このケース内面部分に配置された充電コイルと、この充電コイルに対向する位置に携帯機器を載置可能な設置面とを有する構成となっている。   A conventional charging stand for contactless charging is configured to include a case, a charging coil disposed on the inner surface of the case, and an installation surface on which a portable device can be placed at a position facing the charging coil. .

また、電磁誘導方式の無接点充電は、両充電コイルの位置関係を検知し自動的に位置合わせを行うものや、複数の充電コイルを用いるものなどがある。さらに、送電側と受電側に電極を設置し、電極間に発生する電界を利用してエネルギーを伝送する電界結合型の無接点充電も知られている。このように、無接点充電は、携帯機器を特定の位置に設置しなくとも充電可能としたものが知られている(例えば、これに類似する技術としては、下記特許文献1が存在する)。   In addition, the electromagnetic contact type non-contact charging includes a method in which a positional relationship between both charging coils is detected and the positioning is automatically performed, and a method in which a plurality of charging coils are used. In addition, electric field coupling type non-contact charging in which electrodes are installed on the power transmission side and the power reception side and energy is transmitted using an electric field generated between the electrodes is also known. As described above, non-contact charging is known that enables charging without installing a portable device at a specific position (for example, Patent Document 1 below is present as a similar technique).

前記従来例における課題は、車両の走行中には、効率的な充電が行えない場合があると言うことであった。   The problem with the conventional example is that efficient charging may not be possible while the vehicle is running.

すなわち、車両内において携帯機器の充電を行う時には、ケース内に携帯機器を収納させ、充電装置の充電コイルと、携帯機器の充電コイルを対向させているだけの状態である。よって、自動車の走行中に加わる振動や衝撃で、前記両充電コイルが適切に対向できていない状態が発生し、この時には、効率的な充電が行えない状態が発生してしまうのである。   That is, when charging the portable device in the vehicle, the portable device is housed in the case, and the charging coil of the charging device and the charging coil of the portable device are simply opposed to each other. Therefore, a state in which the two charging coils are not properly opposed to each other occurs due to vibrations or impacts applied during traveling of the automobile, and at this time, a state in which efficient charging cannot be performed occurs.

そこで、本発明は、車両の走行中でも、効率的な充電が行えるようにすることを目的とするものである。   Therefore, an object of the present invention is to enable efficient charging even while a vehicle is running.

そしてこの目的を達成するために本発明は、ケースと、このケース内面部分に配置された充電手段と、この充電手段と平行な位置に携帯機器の充電部をガイドするガイド部と、携帯機器の厚さ方向をガイド部とにより挟持する押さえ部とを有し、押さえ部とガイド部との携帯機器の厚さ方向の距離が、携帯機器の挿入方向に向かって徐々に広くなる構成とし、これにより所期の目的を達成するものである。   In order to achieve this object, the present invention provides a case, a charging unit disposed on the inner surface of the case, a guide unit for guiding the charging unit of the portable device in a position parallel to the charging unit, A holding portion that sandwiches the thickness direction with the guide portion, and the distance in the thickness direction of the portable device between the holding portion and the guide portion gradually increases toward the insertion direction of the portable device. To achieve the intended purpose.

以上のように本発明は、ケースと、このケース内面部分に配置された充電手段と、この充電手段と平行な位置に携帯機器の充電部をガイドするガイド部と、携帯機器の厚さ方向をガイド部とにより挟持する押さえ部とを有し、押さえ部とガイド部との携帯機器の厚さ
方向の距離が、携帯機器の挿入方向に向かって徐々に広くなる構成としたものである。したがって、自動車の走行中でも、携帯機器が移動することがなく、効率的な充電が行える。
As described above, the present invention provides a case, a charging unit disposed on the inner surface of the case, a guide unit that guides the charging unit of the portable device in a position parallel to the charging unit, and a thickness direction of the portable device. A holding portion sandwiched between the guide portion and the distance between the holding portion and the guide portion in the thickness direction of the portable device gradually increases toward the insertion direction of the portable device. Therefore, the mobile device does not move even while the automobile is running, and efficient charging can be performed.

また、厚みの異なる携帯機器をガイド部と押さえ部により挟持する場合も、押さえ部とガイド部との携帯機器の厚さ方向の距離が、携帯機器の挿入方向に向かって徐々に広くなる構成としたものであるので、それぞれの携帯機器の厚さに合わせて押さえ部とガイド部とで挟持することが可能である。   Also, when a portable device having a different thickness is sandwiched between the guide portion and the holding portion, the distance in the thickness direction of the portable device between the holding portion and the guide portion gradually increases toward the insertion direction of the portable device. Therefore, it can be sandwiched between the pressing portion and the guide portion in accordance with the thickness of each portable device.

さらに、携帯機器の厚さにより携帯機器の挟持位置が異なったとしても、ガイド部により充電手段と平行な位置に携帯機器の充電部がガイドされている。電磁誘導方式や電界結合方式の無接点充電装置は、効率よくエネルギーを伝送するには、送電側と受電側を平行な位置関係とすることが好ましい。   Furthermore, even if the holding position of the portable device varies depending on the thickness of the portable device, the charging unit of the portable device is guided by the guide unit to a position parallel to the charging means. In order to transmit energy efficiently, the electromagnetic induction type or electric field coupling type non-contact charging device preferably has a parallel positional relationship between the power transmission side and the power reception side.

よって、厚みの異なる携帯機器であっても、押さえ部とガイド部とで挟持する位置に置くだけで効率よく充電可能な状態にすることが可能であるとともに、携帯機器の充電台への出し入れが非常に簡単で、非常に使い勝手の良いものとなるのである。   Therefore, even portable devices with different thicknesses can be efficiently charged simply by placing them between the holding portion and the guide portion, and the portable device can be taken in and out of the charging stand. It is very simple and very easy to use.

以下、本発明の一実施の形態を、図面を用いて説明する。
(実施の形態1)
図1において、車両本体1の車内2前方にはハンドル3が、またハンドル3左方には車載用電子装置を構成する車載用電子機器4が配置されている。さらにハンドル3左方で、車載用電子機器4下方のコンソールボックス5に、無接点充電用充電台6が配置されている。
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
(Embodiment 1)
In FIG. 1, a handle 3 is disposed in front of the vehicle body 1 in the vehicle 2, and an in-vehicle electronic device 4 constituting an in-vehicle electronic device is disposed on the left side of the handle 3. Further, on the left side of the handle 3, a charging stand 6 for contactless charging is arranged in a console box 5 below the in-vehicle electronic device 4.

図2、3は、図1のコンソールボックス5に埋め込まれた無接点充電用充電台6の斜視図を示している。図4は、無接点充電用充電台6の展開図を示している。   2 and 3 are perspective views of the charging stand 6 for contactless charging embedded in the console box 5 of FIG. FIG. 4 shows a development view of the charging stand 6 for contactless charging.

これら図2、3、4を用いて無接点充電用充電台6について説明する。   The contactless charging base 6 will be described with reference to FIGS.

すなわち、本実施形態の無接点充電用充電台6は、ケース7と、このケース7の内面部分に図3、4に示す充電手段8が配置されている。例えば、充電手段8は、電磁誘導方式であれば充電コイルであり、この充電コイルを移動させるタイプや複数の充電コイルを充電エリア全体に敷き詰めたタイプが代表的である。電界結合型は、被充電体(以降、代表的な携帯機器9で説明する)に設けられた電極との間で電界を発生させる電極である。   That is, in the contactless charging base 6 of this embodiment, a case 7 and the charging means 8 shown in FIGS. For example, the charging means 8 is a charging coil in the case of an electromagnetic induction system, and a type in which the charging coil is moved and a type in which a plurality of charging coils are spread over the entire charging area are typical. The electric field coupling type is an electrode that generates an electric field with an electrode provided on an object to be charged (hereinafter described as a representative portable device 9).

また、この充電手段8と平行な位置に携帯機器9の充電部をガイド部10と、携帯機器9の厚さ方向をガイド部10とにより挟持する押さえ部11とを有する。なお、本実施形態では、ガイド部10とケース7の底面部とを一体に構成しているが、ガイド部10を別部材で設けるようにしてもよい。   In addition, a charging unit of the portable device 9 is provided at a position parallel to the charging unit 8, and a holding unit 11 that sandwiches the thickness direction of the portable device 9 with the guide unit 10. In the present embodiment, the guide portion 10 and the bottom surface portion of the case 7 are integrally formed, but the guide portion 10 may be provided as a separate member.

この押さえ部11は、図4に示すように、ケース7の側壁をケース7の内側へと傾斜させたものである。このようにすれば、押さえ部11は、ガイド部10との携帯機器9の厚さ方向の距離が、携帯機器9の挿入方向に向かって徐々に広くなる構成となる。   As shown in FIG. 4, the pressing portion 11 is formed by inclining the side wall of the case 7 toward the inside of the case 7. In this way, the pressing portion 11 is configured such that the distance in the thickness direction of the portable device 9 from the guide portion 10 gradually increases toward the insertion direction of the portable device 9.

また、押さえ部11は、図4に示すように、携帯機器9の長辺部、および短辺部と接触するようにすれば、携帯機器9が振動により移動することを防止する効果が高くなる。   In addition, as shown in FIG. 4, if the pressing portion 11 is in contact with the long side portion and the short side portion of the mobile device 9, the effect of preventing the mobile device 9 from moving due to vibration is enhanced. .

さらにまた、図5に示すように、ケース7の底面部と一体に構成したガイド部10は、押さえ部11方向へ傾斜を設けた構成とする。なお、図5では、押さえ部11が携帯機器9の長辺部、および短辺部と接触するようにケース7の角部分が最も低くなるようにしているが、携帯機器9の長辺部と短辺部のいずれかの方向に傾斜を設ける構成としてもよい。   Furthermore, as shown in FIG. 5, the guide portion 10 configured integrally with the bottom surface portion of the case 7 is configured to be inclined toward the pressing portion 11. In FIG. 5, the corner portion of the case 7 is made the lowest so that the pressing portion 11 comes into contact with the long side portion and the short side portion of the mobile device 9. It is good also as a structure which provides an inclination in either direction of a short side part.

次に、図5を用いて携帯機器9が無接点充電用充電台6に設置する手順について説明する。   Next, the procedure in which the portable device 9 is installed on the contactless charging base 6 will be described with reference to FIG.

まず、ユーザは、携帯機器9をケース7のガイド部10(底面部)の中央付近に置く。その後、ガイド部10上を滑らすように押さえ部11へ向かって移動させる。この時、前述ように、ガイド部10に傾斜を設けていれば、よりスムーズに携帯機器9を移動させることが可能である。   First, the user places the mobile device 9 near the center of the guide portion 10 (bottom surface portion) of the case 7. Then, it moves toward the holding | suppressing part 11 so that the guide part 10 top may be slid. At this time, as described above, if the guide portion 10 is inclined, the mobile device 9 can be moved more smoothly.

そして、押さえ部11へ移動させられた携帯機器9は、携帯機器9の厚さ方向をガイド部10と押さえ部11とにより挟持される。この際、厚みの異なる携帯機器9が設置されたとしても、押さえ部11は、ガイド部10との携帯機器9の厚さ方向の距離が、携帯機器9の挿入方向に向かって徐々に広くなる構成となっているので、携帯機器9の厚みに応じた位置で挟持される。   Then, the portable device 9 moved to the holding unit 11 is sandwiched between the guide unit 10 and the holding unit 11 in the thickness direction of the portable device 9. At this time, even if the portable devices 9 having different thicknesses are installed, the holding unit 11 gradually increases the distance in the thickness direction of the portable device 9 from the guide unit 10 in the insertion direction of the portable device 9. Since it becomes a structure, it is clamped in the position according to the thickness of the portable apparatus 9.

このように、携帯機器9の厚みにより、挟持される位置が異なったとしても、ガイド部10により充電手段8と平行な位置に携帯機器9の充電部がガイドされている。   Thus, even if the sandwiched position differs depending on the thickness of the mobile device 9, the charging unit of the mobile device 9 is guided by the guide unit 10 to a position parallel to the charging unit 8.

よって、厚みの異なる携帯機器9であっても、押さえ部11とガイド部10とで挟持する位置に置くだけで効率よく充電可能な状態にすることが可能である。さらに、携帯機器9の無接点充電用充電台6への出し入れが非常に簡単で、非常に使い勝手の良いものとなるのである。   Therefore, even if it is the portable apparatus 9 from which thickness differs, it can be made into the state which can be charged efficiently only by putting in the position clamped by the holding | suppressing part 11 and the guide part 10. FIG. Further, it is very easy to put in and take out the portable device 9 to and from the charging stand 6 for contactless charging, and it becomes very easy to use.

次に、図6を用いて、携帯機器9の無接点充電用充電台6からの取り出し手順について説明する。   Next, a procedure for taking out the portable device 9 from the contactless charging base 6 will be described with reference to FIG.

無接点充電用充電台6に置かれた携帯機器9は、押さえ部11とガイド部10とで挟持された状態であるため、真上方向に取り出すことができない。そこで、ケース7の側面部に、ガイド部10の傾斜の上方向きのスリット12を設ける。   Since the portable device 9 placed on the contactless charging base 6 is sandwiched between the pressing portion 11 and the guide portion 10, it cannot be taken out directly upward. In view of this, a slit 12 is provided on the side surface of the case 7 so as to be inclined upward of the guide portion 10.

このようにすれば、指をスリット12に沿わせて動かせば、簡単に無接点充電用充電台6に置かれた携帯機器9を取り出すことができる。例えば、運転中であっても、視線をそらすことなく、携帯機器9を取り出すことができる。   In this way, if the finger is moved along the slit 12, the portable device 9 placed on the contactless charging base 6 can be easily taken out. For example, the portable device 9 can be taken out without diverting the line of sight even during driving.

以上説明したように、本実施形態によれば、ケース7と、このケース7内面部分に配置された充電手段8と、この充電手段8と平行な位置に携帯機器9の充電部をガイドするガイド部10と、携帯機器9の厚さ方向をガイド部10とにより挟持する押さえ部11とを
有し、押さえ部11とガイド部10との携帯機器9の厚さ方向の距離が、携帯機器9の挿入方向に向かって徐々に広くなる構成としたものである。したがって、自動車の走行中でも、携帯機器9が移動することがなく、効率的な充電が行える。
As described above, according to the present embodiment, the case 7, the charging means 8 disposed on the inner surface portion of the case 7, and the guide for guiding the charging unit of the portable device 9 to a position parallel to the charging means 8. Part 10 and a holding part 11 that sandwiches the thickness direction of portable device 9 with guide part 10, and the distance in the thickness direction of portable device 9 between holding part 11 and guide part 10 is It is set as the structure which becomes gradually wide toward the insertion direction. Therefore, the portable device 9 does not move even while the automobile is running, and efficient charging can be performed.

また、厚みの異なる携帯機器9をガイド部10と押さえ部11により挟持する場合も、押さえ部11とガイド部10との携帯機器9の厚さ方向の距離が、携帯機器9の挿入方向に向かって徐々に広くなる構成としたものであるので、それぞれの携帯機器9の厚さに合わせて押さえ部11とガイド部10とで挟持することが可能である。   Even when the portable device 9 having a different thickness is sandwiched between the guide portion 10 and the holding portion 11, the distance in the thickness direction of the portable device 9 between the holding portion 11 and the guide portion 10 faces the insertion direction of the portable device 9. Therefore, it can be sandwiched between the pressing portion 11 and the guide portion 10 in accordance with the thickness of each portable device 9.

さらに、携帯機器9の厚さにより携帯機器9の挟持位置が異なったとしても、ガイド部10により充電手段8と平行な位置に携帯機器9の充電部がガイドされている。電磁誘導方式や電界結合方式の無接点充電装置は、効率よくエネルギーを伝送するには、送電側と受電側を平行な位置関係とすることが好ましい。   Furthermore, even if the holding position of the portable device 9 varies depending on the thickness of the portable device 9, the charging unit of the portable device 9 is guided by the guide unit 10 to a position parallel to the charging unit 8. In order to transmit energy efficiently, the electromagnetic induction type or electric field coupling type non-contact charging device preferably has a parallel positional relationship between the power transmission side and the power reception side.

よって、厚みの異なる携帯機器9であっても、押さえ部11とガイド部10とで挟持する位置に置くだけで効率よく充電可能な状態にすることが可能であるとともに、携帯機器9の充電台への出し入れが非常に簡単で、非常に使い勝手の良いものとなるのである。   Therefore, even if it is the portable apparatus 9 from which thickness differs, it can be made in the state which can be charged efficiently only by putting it in the position pinched by the holding | suppressing part 11 and the guide part 10, and the charging stand of the portable apparatus 9 It is very easy to put in and out, and is very easy to use.

以上のように本発明は、ケースと、このケース内面部分に配置された充電手段と、この充電手段と平行な位置に携帯機器の充電部をガイドするガイド部と、携帯機器の厚さ方向をガイド部とにより挟持する押さえ部とを有し、押さえ部とガイド部との携帯機器の厚さ方向の距離が、携帯機器の挿入方向に向かって徐々に広くなる構成としたものである。したがって、自動車の走行中でも、携帯機器が移動することがなく、効率的な充電が行える。   As described above, the present invention provides a case, a charging unit disposed on the inner surface of the case, a guide unit that guides the charging unit of the portable device in a position parallel to the charging unit, and a thickness direction of the portable device. A holding portion sandwiched between the guide portion and the distance between the holding portion and the guide portion in the thickness direction of the portable device gradually increases toward the insertion direction of the portable device. Therefore, the mobile device does not move even while the automobile is running, and efficient charging can be performed.

また、厚みの異なる携帯機器をガイド部と押さえ部により挟持する場合も、押さえ部とガイド部との携帯機器の厚さ方向の距離が、携帯機器の挿入方向に向かって徐々に広くなる構成としたものであるので、それぞれの携帯機器の厚さに合わせて押さえ部とガイド部とで挟持することが可能である。   Also, when a portable device having a different thickness is sandwiched between the guide portion and the holding portion, the distance in the thickness direction of the portable device between the holding portion and the guide portion gradually increases toward the insertion direction of the portable device. Therefore, it can be sandwiched between the pressing portion and the guide portion in accordance with the thickness of each portable device.

さらに、携帯機器の厚さにより携帯機器の挟持位置が異なったとしても、ガイド部により充電手段と平行な位置に携帯機器の充電部がガイドされている。電磁誘導方式や電界結合方式の無接点充電装置は、効率よくエネルギーを伝送するには、送電側と受電側を平行な位置関係とすることが好ましい。   Furthermore, even if the holding position of the portable device varies depending on the thickness of the portable device, the charging unit of the portable device is guided by the guide unit to a position parallel to the charging means. In order to transmit energy efficiently, the electromagnetic induction type or electric field coupling type non-contact charging device preferably has a parallel positional relationship between the power transmission side and the power reception side.

よって、厚みの異なる携帯機器であっても、押さえ部とガイド部とで挟持する位置に置くだけで効率よく充電可能な状態にすることが可能であるとともに、携帯機器の充電台への出し入れが非常に簡単で、非常に使い勝手の良いものとなるのである。したがって、車載用電子装置としての活用が期待されるものである。   Therefore, even portable devices with different thicknesses can be efficiently charged simply by placing them between the holding portion and the guide portion, and the portable device can be taken in and out of the charging stand. It is very simple and very easy to use. Therefore, utilization as an in-vehicle electronic device is expected.
