Abstract

Disclosed is an electric vehicle battery attaching/detaching device including a battery mounting unit formed on an electric vehicle to detachably mount a battery and provided with a connector pin module adapted to be lifted/lowered by a lifting/lowering means; a loader having a plurality of battery stands, each battery stand being adapted to detachably mount a fully-charged battery to be exchanged with the battery mounted on the battery mounting unit; and a battery attaching/detaching unit adapted to move along X-axis, Y-axis, and Z-axis between the battery mounting unit and the battery stand by means of a movement device, detach a battery mounted on the battery mounting unit or the battery stand, and exchange/mount the battery on the battery stand or the battery mounting unit.

Claims

1. An electric vehicle battery attaching/detaching device for replacing a battery mounted on an electric vehicle with a fully-charged battery mounted on a battery stand of a loader, comprising:

a battery mounting unit formed on the electric vehicle to detachably mount the battery thereon and provided with a connector pin module adapted to be lifted/lowered by a lifting/lowering means; and

a battery attaching/detaching unit adapted to i) move along X-axis, Y-axis, and Z-axis between the battery mounting unit and the battery stand by means of a movement device, ii) detach the battery mounted on the battery mounting unit, and iii) mount the fully-charged battery on the battery mounting unit,

wherein the battery has an introduction space unit formed on a side of a bottom surface of the battery so that the connector pin module is introduced in the introduction space unit when lifted.

2. The electric vehicle battery attaching/detaching device as claimed in claim 1, wherein the battery has a connector pin hole formed on a surface of the introduction space unit so that a connector pin of the connector pin module is inserted into the connector pin hole.

3. The electric vehicle battery attaching/detaching device as claimed in claim 2, wherein grasping protrusions are formed on both sides of the connector pin, a fitting groove being formed on a circumferential surface of each grasping protrusion, and grasping holes are formed on both sides of the connector pin hole so that the grasping protrusions are fitted, a leaf spring being installed on a circumferential surface of each grasping hole to be fitted into the fitting groove.

4. An electric vehicle battery attaching/detaching device for replacing a battery mounted on an electric vehicle with a fully-charged battery mounted on a battery stand of a loader, comprising:

a battery mounting unit formed on the electric vehicle to detachably mount the battery thereon and provided with a connector pin module adapted to be lifted/lowered by a lifting/lowering means; and

a battery attaching/detaching unit adapted to i) move along X-axis, Y-axis, and Z-axis between the battery mounting unit and the battery stand by means of a movement device, ii) detach the battery mounted on the battery mounting unit, and iii) mount the fully-charged battery on the battery mounting unit,

wherein the lifting/lowering means comprises;

an actuator adapted to operate in response to an electric signal;

a piston adapted to be moved by operation of the actuator;

a slide member connected to an end of the piston so that movement of the slide member is interlinked with movement of the piston; and

links having ends connected to the slide member, respectively, so that, when the slide member moves, the links rotate from a horizontal direction to a vertical direction or from a vertical direction to a horizontal direction and lift/lower the connector pin module.
