[0007]

When the fixing of the battery case 4 is released, for example, when the nut 10 is loosened and the bolt 9 is released, the heavy battery case 4 is released.
By applying the leverage effect of the parallel link mechanism, it is possible to slowly and safely lower the ground 30 with human power. By disconnecting the link fulcrum 27 from the battery case 4,
The battery case 4 is separated from the two-wheeled vehicle, and can be moved on the ground by the wheels 8 to move to, for example, a charging place. After the battery 3 is charged, the battery case 4 is transported to a position directly below the frame 6 of the electric motorcycle, and the links are connected to the fulcrum 27 of the battery case 4, and then the link that also serves as the foot step 7 is stepped down with a foot. As a result, the heavy battery case 4 is lifted by the leverage to a state in which the heavy battery case 4 is lightly and safely abutted under the frame 6 by human power by the parallel movement of the parallel link mechanism. As a fixing means for the battery case 4, a nut 10 is screwed into the bolt 9 of the battery case 4 from above the frame 6, whereby the battery case 4 is eventually pulled up and firmly fixed by the screw motion. The foot step 7 is used for putting a passenger on the foot while the electric motorcycle is running. At least one bolt 9 is provided with a nut 10 in a box-shaped casing 12 under a seat 11 which can be opened and closed and locked.
Since the battery 3 is screwed and fixed, it is possible to reliably prevent the battery 3 from being stolen or mischievous.

The control circuit device 13 is detachably mounted only from the inside in the box-shaped casing 12 under the seat 11 which can be opened and closed and the battery and the connector 36 for detaching the control circuit are also installed. Can be reliably prevented.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
FIG. 1 shows an electric scooter that runs by driving a rear wheel 2 with a motor 1 attached to a tip end of a swing arm 20. Under the substantially U-shaped frame 6 supporting the front wheels 5 and the driving wheels (rear wheels) 2 supported by the steering shaft 21, many batteries 3 accommodated in the battery case 4 are supported. The battery case 4 is configured to have sufficient strength and rigidity with respect to the weight of the battery 3 having a total amount of 20 kg to 50 kg. At the positions on both sides of the battery case 4, one end of the middle part of the long link 18 and one end of the short link 19 formed at the foot step 7 are rotated by the shafts 25 and 26 to the brackets 23 and 24 of the frame 6, respectively. Mounted freely. The two links 18 and 19 are arranged at the same angle from the positions of the shafts 25 and 26, respectively, and are rotatably connected at the same length by detachable bolts 27 as shown in FIG. A parallel link mechanism is configured.

Therefore, when the link 18 provided with the foot step 7 is rotated by lifting by hand, the heavy battery case 4 can be slowly and comfortably lowered onto the ground 30 by leverage and horizontal translation. And bolt 2
By loosening and removing the battery case 7, the battery case 4 is released from the scooter and can be moved independently. Therefore, three or four free casters 8 are attached to the lower surface of the battery case 4. The free caster 8 allows the battery case 4 to be lightly and easily moved on the ground to a target direction and location, for example, a location of a battery 3 charging facility. Of course, the charged battery case 4 or a new battery case is driven under the scooter frame 6, and the links 18, 1
The parallel movement of the parallel link mechanism applying the so-called leverage operation of pressing down the foot step 7 with the foot after connecting the bolt 9 to the foot 9 with the bolt 27 makes it possible to easily, reliably and safely load a heavy battery with a relatively light force. It can be installed under. Such an operation is performed after the scooter is stopped by the stand 40.

The battery case 4 mounted and lifted to below the frame 6 of the scooter is fixed in its mounting position to the frame 6 by various fixing means. As a preferable fixing means, in the illustrated embodiment, two vertically upward (but not limited to) bolts 9 project upward from the upper surface of the battery case 4. The bolt 9
Is a bracket 31 provided on the frame 6 of the scooter.
Through the bolt hole and project upward. In particular, one bolt 9 is openable and closable about a hinge 32 and faces into a box-shaped casing 12 fixedly provided on the frame 6 below the occupant seat 11 which can be locked by a locking device 33 (FIG. 5). It is arranged to protrude. Therefore, the battery 10 pushed up by the application of the parallel link mechanism as described above by screwing the nut 10 from above the frame 6 to the bolt 9 protruding upward through the bolt hole of the bracket 31 as described above. Finally, the case 4 can be completely pulled up and completely fixed under the frame 6. In addition, since one nut 10 is screwed into the bolt 9 in the box-shaped casing 12, it is impossible to lower the battery case 4 unless the sheet 11 is unlocked and opened. The effect of preventing mischief is enormous. Thus, the battery case 4 has the nut 1
After being fixed at 0, it is no problem for the occupant to put his foot on the footstep 7 when the scooter is running.

Next, the electric scooter is controlled by a side wall plate in the box-shaped casing 12 fixed to the frame 6 below the seat 11 which can be opened and closed about the hinge 32 and can be locked by the locking device 33 as described above. The circuit device 13 is detachably attached only from inside the casing 12 by screws 34, 34 facing outward from the inside. Control circuit device 13
The heat radiating portion 13a is exposed outside the casing. FIG.
Reference numeral 35 denotes a waterproof and vibration-proof rubber.

A detachable connector 36 for connecting a battery and a control circuit is provided in the box-shaped casing 12 below the seat 11 which can be opened and closed as described above and which can be locked. Further, a winding projection 17 for winding and storing a cord 16 with an outlet 15 for supplying power to a charger (not shown) is provided on the lower surface of the sheet 11 in a substantially circular arrangement. The cord 16 is wound around the winding projection 17 and is compactly stored in the box-shaped casing 12. At the time of charging, the cord 16 is pulled out through a notch 38 provided at the upper edge of the box-shaped casing 12, and power is supplied to the charger with the sheet 11 closed and locked.

In any case, since the control circuit device 13, the detachable connector 36, and the power supply cord 16 are housed in the box-shaped casing 12 below the lockable sheet 11, the effect of preventing theft and mischief is reduced. It is overwhelming. In addition,
The present invention can be similarly implemented with a configuration in which a winding type code reel is provided instead of the winding projection 17.

[0015]

[Effects of the present invention] The electric motorcycle according to the present invention is capable of attaching and detaching a very heavy battery, can be quickly and safely performed by human power by means of leverage, and is completely prevented from being stolen or mischievous. Practicality is greatly enhanced.
