Self-aligning battery changing system for electric battery-powered vehicles
First Claim
1. A battery and battery lifting system for a mining or construction vehicle, the vehicle having a frame, the system comprising:
- a battery;
an arm for lifting the battery, the lifting arm having means for pivotally coupling to the frame; and
a means for aligning the battery with the lifting arm, the aligning means having a wedge-shaped profile, the aligning means includes vertical sidewalls in the battery, the vertical sidewalls extend toward convergence, each of the first and second lifting arms includes opposing outer and inner sidewalls, the opposing outer and inner sidewalls extend toward convergence in a direction away from the vehicle, whereby the battery is guided and aligned with the lifting arm as the lifting arm moves inwardly in the direction of convergence along the vertical sidewalls.

Abstract
A battery and battery lifting system for a mining or construction vehicle, the vehicle having a frame, the system having a battery, the battery having at least one slot, the at least one slot having vertical sidewalls which extend toward convergence, and at least one wedge-shaped arm for lifting the battery, the at least one wedge-shaped lifting arm having a bellcrank and a leveling arm for pivotally coupling to the frame, whereby the at least one wedge-shaped lifting arm is guided and aligned with the battery as the at least one wedge-shaped lifting arm moves inwardly in the direction of convergence along the vertical sidewalls. The at least one wedge-shaped lifting arm having a hydraulic cylinder. The hydraulic cylinder having a shaft with a locking plate located at the end of the shaft. The locking plate is used to lock the battery to the at least one wedge-shaped lifting arm.

7. A battery and battery lifting system for a mining or construction vehicle, the vehicle having a frame, the system comprising:
-
a battery, the battery having a first side and a second side, the second side opposite from the first side, the second side having a first and second slot, each slot substantially extending towards the first side, each slot having a distal end and a proximal end, the proximal end of the slot being adjacent the second side and the distal end of the slot being adjacent the first side, each of the first and second slot having first and second opposing vertical walls, each of the first and second opposing vertical walls extending towards convergence in the direction towards the first side, and a first and second lifting arm, each of said first and second lifting arms being pivotally coupled to the frame and adapted to be inserted into a respective one of the first and second slots of the battery, each of the first and second lifting arms includes opposing outer and inner sidewalls, the opposing outer and inner sidewalls extend toward convergence in a direction away from the vehicle, whereby the first and second opposing vertical walls align the battery with the first and second lifting arms as the first and second lifting arms are inserted into the first and second slots along the first and second opposing vertical walls. - View Dependent Claims (8, 9)
