Abstract

An electric work vehicle includes: a battery accommodating portion that is provided in the vehicle body and accommodates a battery; a first connector provided on the battery accommodating portion; a second connector provided on the battery; and an operating tool for moving the battery and the second connector, and switching from a pre-attachment orientation in which the second connector opposes the first connector to an attachment orientation in which the second connector is joined to the first connector.

Claims (48)

1. An electric work vehicle comprising:

a vehicle body;

a battery accommodating portion that is provided in the vehicle body and accommodates a battery;

a first connector provided on the battery accommodating portion;

a second connector provided on the battery; and

an operating tool for moving the battery and the second connector, and switching from a pre-attachment orientation in which the second connector opposes the first connector to an attachment orientation in which the second connector is joined to the first connector,

wherein at least a portion of the first connector is connected to the operating tool.

2. The electric work vehicle according to claim 1 , further comprising:

a stopper for inhibiting movement of the battery beyond the attachment orientation, wherein the battery is fixed to the battery accommodating portion by the stopper inhibiting the movement, and the operating tool biasing the battery toward the attachment orientation from the pre-attachment orientation.

3. An electric work vehicle comprising:

a vehicle body;

a battery accommodating portion that is provided in the vehicle body and accommodates a battery;

a first connector provided on the battery accommodating portion;

a second connector provided on the battery; and

an operating tool for moving the battery and the second connector, and switching from a pre-attachment orientation in which the second connector opposes the first connector to an attachment orientation in which the second connector is joined to the first connector,

wherein the operating tool includes:

a bracket fixed to the vehicle body;

an operating lever that is pivotal between a first pivot position and a second pivot position around a first lateral axis extending through the bracket; and

a connecting body connected to the operating lever and pivotal around a second lateral axis extending through the operating lever, a locking portion being formed at a free end of the connecting body, and the locking portion being configured to be locked at a locked portion that is formed on the battery when the operating tool assumes the pre-attachment orientation,

wherein in response to pivotal movement of the operating lever from the first pivot position to the second pivot position in a locked state where the locking portion is locked at the locked portion, the second lateral axis moves toward the first connector, and the first connector and the second connector are joined to each other, and

wherein:

the first connector is configured to be moved relative to the vehicle body, and

the first connector is connected to the operating lever such that the first connector moves toward the second connector in response to the pivotal movement of the operating lever from the first pivot position to the second pivot position.

4. The electric work vehicle according to claim 3 , wherein

in the locked state, the connecting body functions as a holding mechanism for holding the operating lever at the second pivot position.

5. An electric work vehicle comprising:

a vehicle body;

a battery accommodating portion that is provided in the vehicle body and accommodates a battery;

a first connector provided on the battery accommodating portion;

a second connector provided on the battery; and

an operating tool for moving the battery and the second connector, and switching from a pre-attachment orientation in which the second connector opposes the first connector to an attachment orientation in which the second connector is joined to the first connector,

wherein the operating tool includes:

a bracket fixed to the vehicle body;

an operating lever that is pivotal between a first pivot position and a second pivot position around a first lateral axis extending through the bracket; and

a connecting body connected to the operating lever and pivotal around a second lateral axis extending through the operating lever, a locking portion being formed at a free end of the connecting body, and the locking portion being configured to be locked at a locked portion that is formed on the battery when the operating tool assumes the pre-attachment orientation,

wherein in response to pivotal movement of the operating lever from the first pivot position to the second pivot position in a locked state where the locking portion is locked at the locked portion, the second lateral axis moves toward the first connector, and the first connector and the second connector are joined to each other, and

wherein:

the connecting body has two vertical pieces and a lateral piece located between the vertical pieces,

the locking portion is formed at each of opposite ends of the lateral piece, and

the locked portion is located on each of opposite sides of the second connector to be locked with the locking portion associated therewith.

6. An electric work vehicle comprising:

a vehicle body;

a battery accommodating portion that is provided in the vehicle body and accommodates a battery;

a first connector provided on the battery accommodating portion;

a second connector provided on the battery;

an operating tool for moving the battery and the second connector, and switching from a pre-attachment orientation in which the second connector opposes the first connector to an attachment orientation in which the second connector is joined to the first connector;

a carrier for accommodating the battery; and

a guiding mechanism for guiding the carrier toward the battery accommodating portion from outside of the vehicle body, the guiding mechanism including guide rails attached to both side faces of the battery accommodating portion, and guide rollers attached to opposite side faces of the carrier and guided by the guide rails.
