Abstract
Description
本発明は、電動二輪車の技術分野に関し、より詳しくは、電動二輪車の一体型動力機構に関する。 The present invention relates to the technical field of electric motorcycles, and more particularly, to an integrated power mechanism for an electric motorcycle.
一般的な電動二輪車は主にモーターを動力源とし、且つ伝動装置によりトルクを車輪に伝動して車両を駆動させて走行させている。前記モーターのシャフトの回転速度はコントローラにより制御されている。 2. Description of the Related Art A general electric motorcycle mainly uses a motor as a power source, and transmits torque to wheels by a transmission device to drive the vehicle to travel. The rotation speed of the motor shaft is controlled by a controller.
従来は、前記モーターがケースに装設され、前記コントローラを回路基板としてボックス内に装設される。前記ボックス及び前記ケースは独立した部材であり、前記モーター及び前記回路基板は適切な導線によって電気的に接続する必要がある。 Conventionally, the motor is mounted in a case, and the controller is mounted in a box using the controller as a circuit board. The box and the case are independent members, and the motor and the circuit board need to be electrically connected by appropriate conductors.
しかしながら、前述した従来の技術では、前記ケース及び前記ボックスが独立した部材であるため、前記ケース及び前記ボックスの両者の体積が占める空間が大きくなった。このため、回路基板を前記ケース内に統合する場合、前記回路基板は四角形の板状であるため、ケースの空間利用率が下がり、体積を効果的に縮小することができなかった。 However, in the above-described related art, since the case and the box are independent members, the space occupied by both the case and the box is increased. For this reason, when the circuit board is integrated in the case, the circuit board has a rectangular plate shape, so that the space utilization rate of the case is reduced and the volume cannot be effectively reduced.
そこで、本発明者は上記の欠点が改善可能と考え、鋭意検討を重ねた結果、合理的設計で上記の課題を効果的に改善する本発明の提案に到った。 Therefore, the present inventor considered that the above-mentioned disadvantages can be improved, and as a result of intensive studies, came to a proposal of the present invention that effectively improves the above-mentioned problems with a rational design.
本発明はこうした状況に鑑みてなされたものであり、その目的は、電動二輪車の制御システムを提供することにある。そして、回路基板をケース内に統合可能であり、前記回路基板は前記ケースのモーターのシャフトに近接するように装設され、これにより統合後の前記ケースの体積が縮小される。 The present invention has been made in view of such circumstances, and an object thereof is to provide a control system for an electric motorcycle. Then, the circuit board can be integrated in the case, and the circuit board is mounted close to the shaft of the motor of the case, thereby reducing the volume of the case after integration.
また、本発明の他の目的は、電動二輪車の制御システムを提供する。そして、ケース内部の分画される冷却スペースが前記回路基板に隣接し、前記回路基板が発生させる熱量が前記冷却スペースに導熱されることにより、放熱効率が高まる。 Another object of the present invention is to provide a control system for an electric motorcycle. The cooling space divided inside the case is adjacent to the circuit board, and the amount of heat generated by the circuit board is conducted to the cooling space, so that the heat radiation efficiency increases.
上述した課題を解決し、目的を達成するために、本発明に係る電動二輪車の制御システムは、ケース内部に装設される電動モーターのシャフトの回転速度の制御に用いられ、且つ前記ケース内部に形成される組立空間と、前記組立空間内に装設されると共に前記電動モーターに電気的に接続される回路基板と、前記回路基板の一側に形成される凹部と、を備える。 In order to solve the above-described problems and achieve the object, a control system for an electric motorcycle according to the present invention is used for controlling a rotation speed of a shaft of an electric motor provided inside a case, and is provided inside the case. An assembly space is formed, a circuit board installed in the assembly space and electrically connected to the electric motor, and a recess formed on one side of the circuit board.
これにより前記回路基板が前記シャフトに向けて近接し、前記シャフトが前記凹部の範囲内に進入し、組み合わせ形態となって占領する空間を少なくし、ケースの体積を縮小する効果を達成させる。 Thereby, the circuit board approaches the shaft, the shaft enters the area of the concave portion, and the space occupied in the combined form is reduced, and the effect of reducing the volume of the case is achieved.
また、前記組立空間の対向する一側には冷却スペースを有し、前記回路基板が発生させる熱量が前記冷却スペースに導熱されることにより、放熱効果が高まる。 Further, a cooling space is provided on one side of the assembling space that is opposite to the assembling space, and the amount of heat generated by the circuit board is conducted to the cooling space, thereby increasing a heat radiation effect.
本発明によれば、従来の回路基板がケース内に統合されても体積を効果的に縮小できないと言う欠点を解決させる。 According to the present invention, it is possible to solve the disadvantage that the volume cannot be effectively reduced even when the conventional circuit board is integrated in the case.
本発明における好適な実施の形態について、添付図面を参照して説明する。尚、以下に説明する実施の形態は、特許請求の範囲に記載された本発明の内容を限定するものではない。また、以下に説明される構成の全てが、本発明の必須要件であるとは限らない。 Preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments described below do not limit the contents of the present invention described in the claims. In addition, all of the configurations described below are not necessarily indispensable requirements of the present invention.
電動二輪車の動力部材はケース１０の内部に電動モーター１２及び従動ギア１４が配置される（図１参照）。また、制御システム（図示省略）が前記ケースに結合されると共に前記電動モーター１２に電気的に接続される。前記制御システムは前記電動モーター１２の回転速度の制御に用いられる。 As a power member of the electric motorcycle, an electric motor 12 and a driven gear 14 are arranged inside a case 10 (see FIG. 1). A control system (not shown) is coupled to the case and is electrically connected to the electric motor 12. The control system is used for controlling the rotation speed of the electric motor 12.
図２及び図３に示されるように、前記ケース１０はベース２０に接合台３０が結合される。分離層４０は前記ベース２０に形成され、前記分離層４０の一側を組立空間５０とし（図３参照）、前記電動モーター１２の前記シャフト１６の一端は前記分離層４０から前記組立空間５０まで貫通させる。ちなみに、カバー１８は前記分離層４０に取り付けられ、前記シャフト１６の一端は前記カバー１８内に収容される。 As shown in FIGS. 2 and 3, the case 10 has a base 20 and a joining table 30 joined thereto. The separation layer 40 is formed on the base 20, and one side of the separation layer 40 is defined as an assembly space 50 (see FIG. 3), and one end of the shaft 16 of the electric motor 12 extends from the separation layer 40 to the assembly space 50. Let through. Incidentally, the cover 18 is attached to the separation layer 40, and one end of the shaft 16 is accommodated in the cover 18.
なお、図３及び図４に示されるように、本発明の実施形態では回路基板６０を備える。前記回路基板６０の一側には凹部６２を有する。前記回路基板６０は前記組立空間５０内に装設され、特に、前記回路基板６０が前記シャフト１６に向けて近接することにより、前記シャフト１６が前記凹部６２の範囲内に進入する。前記回路基板６０は制御システムの構成部材であり、且つ前記電動モーター（図示省略）に電気的に接続される。蓋６４は前記組立空間５０を閉鎖するために用いられる。 Note that, as shown in FIGS. 3 and 4, the embodiment of the present invention includes a circuit board 60. One side of the circuit board 60 has a concave portion 62. The circuit board 60 is installed in the assembly space 50. In particular, when the circuit board 60 approaches the shaft 16, the shaft 16 enters the area of the recess 62. The circuit board 60 is a component of the control system, and is electrically connected to the electric motor (not shown). The lid 64 is used to close the assembly space 50.
前記シャフト１６が前記凹部６２の範囲を通過させるため、前記回路基板６０が前記シャフト１６に更に接近する。換言すれば、前記シャフト１６及び前記回路基板６０が占領する空間が減少し、前記ケース１０の体積が縮小する。 Since the shaft 16 passes through the area of the concave portion 62, the circuit board 60 comes closer to the shaft 16. In other words, the space occupied by the shaft 16 and the circuit board 60 is reduced, and the volume of the case 10 is reduced.
図５に示されるように、前記分離層４０の一側は前記組立空間５０とし、前記回路基板６０は前記組立空間５０内に装設されると共に前記分離層４０に近接する。さらに、前記分離層４０の他側は冷却スペース７０とする。これにより、前記冷却スペース７０及び前記回路基板６０が前記分離層４０の相違する両側にそれぞれ位置され、前記回路基板６０が発生させる熱量が前記分離層４０に導熱されて放熱される。さらに、前記冷却スペース７０内部には潤滑油やエンジンオイル等の油液が充填可能であり、このため前記分離層４０からの熱量が高速に吸収される。 As shown in FIG. 5, one side of the separation layer 40 is the assembly space 50, and the circuit board 60 is installed in the assembly space 50 and is close to the separation layer 40. Further, the other side of the separation layer 40 is a cooling space 70. Accordingly, the cooling space 70 and the circuit board 60 are located on different sides of the separation layer 40, respectively, and the amount of heat generated by the circuit board 60 is conducted to the separation layer 40 and radiated. Further, the inside of the cooling space 70 can be filled with an oil liquid such as a lubricating oil or an engine oil, so that the amount of heat from the separation layer 40 is absorbed at a high speed.
図２及び図５に戻って、前記冷却スペース７０は複数のリブ７２を有する。これにより、油液が前記冷却スペース７０まで流動することで生じた気泡が、各リブ７２により即時除去される。また、各リブ７２により前記冷却スペース７０の表面積が広がるため、放熱効率が更に高まる。 Returning to FIGS. 2 and 5, the cooling space 70 has a plurality of ribs 72. As a result, air bubbles generated by the flow of the oil liquid to the cooling space 70 are immediately removed by the ribs 72. Further, since the surface area of the cooling space 70 is increased by each rib 72, the heat radiation efficiency is further improved.
本実施形態に係る制御システムは回路基板構造及び放熱構造を備え、前記回路基板構造は前記シャフトに適合するように特定の形状を呈し、両者の組み合わせが占める空間が減少し、前記ケースの体積も縮小する。また、前記放熱構造は前記回路基板の一側に近接し、且つ前記動力部材内部にある油液により放熱を行うため、放熱機構を別途設計せずとも優れた放熱効果を発揮する。 The control system according to the present embodiment includes a circuit board structure and a heat radiation structure, the circuit board structure has a specific shape so as to fit the shaft, a space occupied by a combination of the two is reduced, and the volume of the case is also reduced. to shrink. In addition, since the heat dissipation structure dissipates heat using an oil liquid inside the power member, which is close to one side of the circuit board, an excellent heat dissipation effect can be achieved without separately designing a heat dissipation mechanism.
以上、本発明の実施形態について図面を参照して詳述したが、具体的な構成はこの実施形態に限られるものではなく、本発明の要旨を逸脱しない範囲の設計変更等も含まれる。 As described above, the embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes a design change or the like without departing from the gist of the present invention.
