Abstract

A device for controllably supporting a battery includes an arm, a first protrusion, a second protrusion, and a cylinder actuator. The arm has a compartment formed in the arm and an opening extending through the arm at a base of the compartment. The cylinder actuator includes a piston connected to a rod, and is positioned substantially in the compartment of the arm. The rod extends toward the opening of the arm, and the rod moves through the opening during operation of the cylinder actuator. Also, the first protrusion extends from the arm in a first direction and the second protrusion extends from the arm in a second direction.

Claims

1. A device for controllably supporting a battery, comprising:

an arm having a compartment formed therein and having an opening extending through the arm at a base of the compartment;

a first protrusion extending from the arm in a first direction providing a first lifting surface for contacting a first portion of the battery;

a second protrusion extending from the arm in a second direction providing a second lifting surface for contacting a second portion of the battery; and

a cylinder actuator positioned in the compartment of the arm, and the cylinder actuator comprising;

a piston configured to translate within the cylinder, and

a rod coupled to the piston, the rod extending from the cylinder actuator toward the opening of the arm,

wherein the rod moves through the opening during operation of the cylinder actuator providing a locking interface with a third portion of the battery.

2. The device of claim 1, wherein the first and second protrusions each have a rounded cross-section along a plane defined vertically along a longitudinal axis of the arm.

3. The device of claim 2, wherein each rounded cross-section includes a periphery defining a circular arc.

4. The device of claim 3, wherein each circular arc is at least 180-degrees.

5. The device of claim 4, wherein the first and second directions are substantially opposite to each other.

6. A system for controllably attaching a battery to a battery-powered vehicle, comprising:

a frame of at least a portion of the vehicle;

an arm rotatably coupled to the frame, the arm comprising;

a first protrusion directed in a first direction;

a second protrusion directed in a second direction; and

a housing for the battery supporting one or more battery cells, the housing comprising a hook and a slot; and

a first actuator, wherein the first actuator selectively rotates the arm relative to the frame such that the first protrusion engages the hook and the second protrusion engages the slot during operation of the system for controllably attaching the battery to the vehicle.

7. The system of claim 6, further comprising:

a second actuator having a locking member coupled thereto, wherein the second actuator selectively engages the locking member, locking together the arm and the housing of the battery.

8. The system of claim 7, wherein the second actuator is at least one of a solenoid, a pneumatic cylinder, or a hydraulic cylinder.

9. The system of claim 8, wherein the second actuator is fastened to the arm, and wherein the second actuator selectively interlocks the locking member with the housing.

10. The system of claim 7, wherein the second actuator is a cylinder actuator, and the locking member is a locking pin that selectively engages an aperture in the housing of the battery when moved by the cylinder actuator.

11. The system of claim 10, further comprising:

a computerized controller in communication with both the first actuator and the second actuator, allowing an operator of the system to both rotate the arm relative to the frame and move the locking pin relative to the aperture in the housing via the controller.

12. The system of claim 10, wherein the slot comprises a concave surface contoured to receive a mating convex surface of the second protrusion.

13. The system of claim 12, wherein the first protrusion comprises a convex surface contoured to fit a second slot formed by the bend of the hook

14. The system of claim 13, wherein the first and second directions are substantially opposite to each other.

15. The system of claim 14, wherein the first direction is defined diagonally upward and toward the vehicle frame, and the second direction is defined diagonally downward and away from the vehicle frame.

16. An mining vehicle powered by battery for hauling mineral deposits, comprising:

a bed section of the vehicle configured to support the mineral deposits;

a tractor section of the vehicle comprising an operator compartment;

an articulated joint between the bed section and the tractor section;

an arm pivotally coupled to the tractor section on a side thereof opposite to the articulated joint, the arm comprising;

a first protrusion extending from an end of the arm,

a second protrusion extending from an underside of the arm, and

a locking mechanism comprising a linearly translatable locking member; and

a cylinder actuator for pivoting the arm relative to the tractor section.

17. The vehicle of claim 16, further comprising:

a battery having a housing comprising;

a first slot contoured to receive the first protrusion,

a second slot contoured to receive the second protrusion, and

an aperture contoured to receive the locking member,

wherein the battery is controllably supported by the arm during operational use of the vehicle.

18. The vehicle of claim 17, wherein the locking mechanism comprises a second cylinder for linearly translating the locking member, and wherein the locking member is a locking pin.

19. The vehicle of claim 18, wherein the second cylinder is positioned substantially within a compartment formed in the arm.

20. The vehicle of claim 19, wherein the first and second protrusions each have a rounded cross-section including a periphery defining a circular arc that is at least 180-degrees.

21. The vehicle of claim 20, wherein the housing of the battery further includes a sloped surface for guiding the first and second protrusions of the arm to the first and second slots of the housing of the battery.
