ATTACH AND DETACH DEVICE OF BATTERY FOR ELECTRIC VEHICLE

摘要

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. A connector pin, which is installed on the battery mounting unit and adapted to ascend/descend, is controlled to ascend, only if the battery is seated and set in the accurate position on the battery mounting unit, and inserted into the connector pin hole of the battery to establish stable electric connection between the battery and the battery mounting unit. Furthermore, the connector pin does not escape from the connector pin hole, even when vibration occurs during running of the electric vehicle, but maintains stable electric connection.
