Abstract

An electric vehicle includes a vehicle frame, a frame connector, a battery compartment, a battery stopper and an anti-connection portion. The battery compartment is provided for receiving a battery unit which has a cable connector connected thereto by a power cable. The battery stopper is mounted to the vehicle frame and movable between a closed position where the battery unit is stopped from removing and an open position where the battery unit is removable. The anti-connection portion is provided on the battery stopper. When the battery stopper is placed in the open position, the anti-connection portion is located at an anti-connection position thereby to prevent the cable connector from being connected to the frame connector. When the battery stopper is placed in the closed position, the anti-connection portion is spaced away from the anti-connection position thereby to allow the cable connector to be connected to the frame connector.

Claims

1. An electric vehicle comprising:

a vehicle frame;

a frame connector provided on the vehicle frame;

a battery compartment for receiving a battery unit which has a cable connector connected thereto by a power cable, wherein the battery unit is removable from the battery compartment in a horizontal direction, wherein the cable connector is connectable to the frame connector;

a battery stopper mounted to the vehicle frame for stopping the battery unit in the battery compartment from removing, wherein the battery stopper is movable between a closed position where the battery unit is stopped from removing and an open position where the battery unit is removable; and

an anti-connection portion provided on the battery stopper;

wherein when the battery stopper is placed in the open position, the anti-connection portion is located at an anti-connection position thereby to prevent the cable connector from being connected to the frame connector, and

wherein when the battery stopper is placed in the closed position, the anti-connection portion is spaced away from the anti-connection position thereby to allow the cable connector to be connected to the frame connector.

2. The electric vehicle according to claim 1, wherein the anti-connection position is a space where the cable connector is placed while connected to the frame connector.

3. The electric vehicle according to claim 1, wherein the anti-connection portion is not movable into the anti-connection position while the cable connector is connected to the frame connector thereby to prevent the battery unit from being removable.

4. The electric vehicle according to claim 1, wherein when the battery stopper is placed in the closed position, the anti-connection portion is located at an opening of the battery compartment.

5. The electric vehicle according to claim 1, wherein the anti-connection portion is an anti-connection member which is fixed to the battery stopper.

6. The electric vehicle according to claim 5, wherein the anti-connection member is provided by an anti-connection bar having a base portion, a preventing portion and an end portion, wherein the base portion has an end which is fixed to the stopper body by welding, the base portion extending from the stopper body in the radial direction of a circle described by any point in the anti-connection bar when the stopper body is pivoted, wherein when the battery stopper is placed in the open position, the preventing portion extends from a distal end of the base portion toward the frame connector in perpendicular relation to the base portion.

7. The electric vehicle according to claim 6, wherein when the battery stopper is placed in the open position, the preventing portion of the anti-connection bar extends from the distal end of the base portion horizontally and obliquely toward a position above a connection of the frame connector.

8. The electric vehicle according to claim 1, wherein the battery stopper is pivotable on the vehicle frame, and wherein the anti-connection portion is pivotable between a position where the anti-connection portion extends along a side of the battery unit and the anti-connection position adjacent to the frame connector.

9. The electric vehicle according to claim 1, wherein a connection of the frame connector is faced upward so that the cable connector is connected from above to the frame connector.

10. The electric vehicle according to claim 1, wherein the battery stopper has a stopper body and a pad which is adjustably mounted to the stopper body and allowed to come in contact with the battery unit, and wherein the anti-connection portion is mounted to the stopper body at the inner lateral surface thereof which faces the battery unit.
