Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electric motorcycle charging device used for charging a motor drive battery of an electric motorcycle.

[Conventional technology]

Conventionally, in an electric motorcycle driven by an electric motor, when charging a motor drive battery, this battery and a charger are connected via a charging cord. An example of a conventional electric vehicle that is charged using a charging cord is disclosed in Japanese Utility Model Publication No. 52-30651. This electric vehicle was configured so that the charging cord connected to the battery was stored under the seat. To charge the battery, the driver had to stand up the seat, pull out the charging cord from the car body, and connect the plug at the end to the charging power source.

[Problem to be solved by the invention]

However, with this structure in which the charging cable is pulled out from the vehicle body each time charging is performed, there is a problem in that the work of connecting and storing the charging cable becomes complicated because charging is performed frequently. Another problem was that it was easy to forget to charge the battery.

[Means to solve the problem]

A charging device for an electric motorcycle according to the present invention is provided with a vehicle-side contact connected to the battery on a stand of an electric motorcycle equipped with a running motor supplied with power from a battery, and a grounding portion of the upright stand. A power supply side contact element connected to a charging power source and in contact with the vehicle side contact element is provided on a base located near the vehicle side contact element.

[For production]

By raising the stand on the base, the vehicle-side contact contacts the power supply-side contact, and the battery is connected to the charging power source.

Note that 36 is a lead wire that connects the electrode piece 32 and a battery (not shown). In addition, when the vehicle side contactor is configured in this way, the electrodes 17 provided on the base 16 are arranged in two stages with an insulating material 37 in between, and the electrode piece 32 is placed on the lower electrode 17, and the electrode piece 32 is placed on the upper electrode 17. Sliders 15c are connected to the electrodes 17, respectively. In this way, the polarity of the DC power supply that is supplied to the two vehicle-side contacts will always remain constant even if the orientation of the vehicle body is changed.

The electrode pieces 33, 34 shown in FIG. 6 are each fixed to the grounding part 31a via an insulating material 38, and are connected to a diode bridge circuit (not shown) via lead wires 39, 40.
