Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-described electric motor cycle, the PCU as the motor control unit is disposed at a low position below the motor and the lower battery. Therefore, when the electric motor cycle travels in water such as a puddle, the electrical connection part between the PCU and the battery may get wet with water. However, if the entire PCU and the battery are disposed at a high position in order to dispose the electrical connection part between the PCU and the battery at a high position, the position of the center of gravity of the vehicle becomes high. An object of the present invention is to dispose the electrical connection part between the motor control unit and the battery at a high position in an electric saddle-riding type vehicle and to lower the position of the center of gravity of the vehicle.

Means for Solving the Problems

[0005] An electric saddle-type vehicle according to one aspect of the present invention comprises wheels, a motor, a battery, and a motor control unit. The motor drives the wheels. The battery is positioned above the motor. The motor control unit is positioned in front of the motor and battery. The motor control unit overlaps with the motor and battery in the longitudinal direction of the vehicle.

[0006] In the electric saddle-type vehicle according to this embodiment, the motor control unit is positioned in front of the motor and battery, and overlaps with the motor and battery in the longitudinal direction of the vehicle. Therefore, the motor control unit can be positioned at a high position. This allows the electrical connection between the motor control unit and the battery to be positioned at a high position. In addition, the battery can be positioned at a lower position compared to when the motor control unit is positioned below the battery. This allows the center of gravity of the vehicle to be lowered.

[0007] The battery may include a bottom surface and a first connector. The first connector may be electrically connected to the motor control unit. The first connector may be located above the bottom surface of the battery. In this case, the first connector is positioned at a higher location, which helps to prevent the first connector from getting wet.

[0008] The motor control unit may include a second connector. The second connector may be electrically connected to the battery. The second connector may be located above the bottom surface of the battery. In this case, the second connector is positioned at a higher location, which helps to prevent it from getting wet.

[0009] The battery may include a stepped section. The stepped section may be located at the front of the bottom surface. The stepped section may have a shape that is recessed upwards. The second connector may be positioned opposite the stepped section. In this case, the second connector is positioned at a higher position. This reduces the likelihood of the second connector getting wet.

[0010] The electric saddle-type vehicle may further include a cable connecting the first connector and the second connector. In this case, the first connector and the second connector can be easily connected by the cable. The first connector may be inserted into the second connector from above. In this case, the first connector and the second connector can be easily connected. The first connector may be provided on a stepped section. In this case, the first connector is provided at a higher position while preventing the battery position from becoming too high.

[0011] The stepped section may include a first surface and a second surface. The first surface may extend upward from the bottom surface. The second surface may extend forward from the first surface. The motor control unit may overlap the second surface in the vertical direction. In this case, the motor control unit and the battery are compactly arranged in the vehicle's longitudinal direction. The motor control unit may overlap the first surface in the vehicle's longitudinal direction. In this case, the position of the battery is kept from becoming too high.

[0012] The battery may be attached to the motor. In this case, the heavy battery and motor can be placed in a low position. This allows the vehicle's center of gravity to be lowered.

[0013] The electric saddle vehicle may further include a front wheel, a front fork, a head pipe, and a seat. The front fork may rotatably support the front wheel. The head pipe may swivel the front fork from side to side. The seat may be located behind the head pipe. The battery may be located below the seat.

[0014] The battery may include a battery case, a first battery module, and a second battery module. The first battery module may include a plurality of first battery cells. The first battery module may be located inside the battery case. The second battery module may include a plurality of second battery cells. The second battery module may be located inside the battery case. The second battery module may be located above the first battery module. The second battery module may be positioned forward relative to the first battery module. In this case, the shape of the rear of the battery can be made less likely to come into contact with the rider's feet. This improves the rider's riding comfort.

[0015] The rear surface of the second battery module may be positioned further forward than the rear surface of the first battery module. In this case, the shape of the rear of the battery can be designed to be less likely to come into contact with the rider's feet, thereby improving the rider's comfort.

[0016] At least a portion of the battery may be located behind the front edge of the seat. In this case, the battery and the seat are compactly arranged in the front-to-back direction.

[0017] The second battery module may have the same shape as the first battery module. In this case, compared to the case where the second battery module is smaller than the first battery module, contact between the rear of the battery and the rider's feet is reduced, and a larger battery capacity can be secured.

[0018] The top surface of the battery may include an inclined surface. The inclined surface may support the front edge of the seat. In this case, the battery and the seat are compactly arranged, and the seat is firmly supported.

[0019] The battery may supply power to the motor. The motor control unit may control the motor. [Effects of the Invention]

[0020] According to the present invention, in an electric saddle-riding type vehicle, an electrical connection portion between a motor control unit and a battery is disposed at a high position, and the position of the center of gravity of the vehicle is lowered.

The first connector 39A may be inserted into the second connector 67A from above. In addition, in the modified form, two first connectors and two second connectors may be provided, similar to the embodiment described above.

[0061] The structure of the battery 18 is not limited to that of the above embodiment and may be modified. For example, the number of first battery cells 811 and the number of second battery cells 821 are not limited to those of the above embodiment and may be modified. The number of battery modules is not limited to two, but may be three or more. For example, the battery 18 may further include a third battery module. The third battery module, like the second battery module 82, may have the same shape as the first battery module 81 and may be positioned offset forward relative to the first battery module 81.
