Abstract

A vehicle includes an upper frame, a lower frame, a front frame, a rear frame, a pair of rear wheels, a drive motor to drive the pair of rear wheels, a battery supported by the upper frame and the lower frame to supply electric power to the drive motor, a straddled seat at a higher position than the drive motor, and a bar handle at a higher position than the straddled seat. The battery includes a battery lower portion and a battery upper portion. The battery upper portion includes a projection that overhangs in at least a horizontal direction with respect to the battery lower portion. At least a portion of the drive motor is below or directly below the projection.

First claim

What is claimed is:

1. A vehicle comprising:
an upper frame;
a lower frame;
a front frame connecting a front portion of the upper frame with the lower frame;
a rear frame connecting a rear portion of the upper frame with a rear portion of the lower frame;
a pair of rear wheels;
a drive motor to drive the pair of rear wheels; and
a battery supported by the upper frame and the lower frame to supply electric power to the drive motor; wherein
the battery includes a battery lower portion and a battery upper portion above the battery lower portion;
the battery upper portion includes a projection that overhangs in at least a horizontal direction with respect to the battery lower portion; and
at least a portion of the drive motor is below the projection.

2. The vehicle according to claim 1 , wherein a length of the battery upper portion is greater than a length of the battery lower portion in a side view of the vehicle.

3. The vehicle according to claim 1 , wherein an area of a cross section of the battery upper portion is greater than an area of a cross section of the battery lower portion in the horizontal direction.

4. The vehicle according to claim 1 , wherein the projection overhangs rearward with respect to the battery lower portion.

5. The vehicle according to claim 1 , wherein the battery includes a battery case that includes the projection.

6. The vehicle according to claim 1 , wherein the battery upper portion projects forward with respect to the battery lower portion and corresponds to a shape of the front frame.

7. The vehicle according to claim 1 , wherein the battery upper portion overhangs forward and rearward with respect to the battery lower portion.

8. The vehicle according to claim 1 , wherein a lateral width of the battery upper portion is equal or substantially equal to a lateral width of the battery lower portion.

9. The vehicle according to claim 1 , further comprising a charging/discharging connector in the battery upper portion that does not protrude from a front end or a rear end of the battery upper portion.

10. The vehicle according to claim 9 , wherein the battery upper portion further includes a slanted portion including the charging/discharging connector.

11. The vehicle according to claim 1 , further comprising an elastic member between the battery and at least one of the upper frame and the lower frame.

12. The vehicle according to claim 1 , further comprising:
a straddled seat at a higher position than the drive motor; and
a bar handle is at a higher position than the straddled seat.
