Abstract

A modular battery system for a material handling vehicle is provided. The modular battery system includes a counterweight assembly, a battery assembly enclosing a power source and including a battery base, and a pair of channels removably coupled to the battery base and laterally separated from one another to define a counterweight slot therebetween. The battery assembly is configured to be slidably installed onto the counterweight assembly with the counterweight assembly received within the counterweight slot defined between the pair of channels.

First claim

We claim:

1. A modular battery system for a material handling vehicle, the modular battery system comprising:
a counterweight assembly;
a battery assembly enclosing a power source and including a battery base; and
a pair of channels removably coupled to the battery base and laterally separated from one another to define a counterweight slot therebetween, wherein the battery assembly is configured to be slidably installed onto the counterweight assembly with the counterweight assembly received within the counterweight slot defined between the pair of channels.

2. The modular battery system of claim 1 , further comprising at least one roller bearing coupled to the counterweight assembly and configured to provide a rolling interface between the pair of channels and the counterweight assembly.

3. The modular battery system of claim 1 , wherein the counterweight assembly includes a central block protruding from a central base, and wherein the central block defines a first lateral surface and a second lateral surface.

4. The modular battery system of claim 3 , wherein the each of the first lateral surface and the second lateral surface includes at least two roller bearings that are longitudinally separated from one another.

5. The modular battery system of claim 4 , wherein each of the first lateral surface and the second lateral surface includes a first bearing spacer arranged longitudinally between the at least two roller bearings and a second bearing spacer arranged adjacent to a back side of the counterweight assembly.

6. The modular battery system of claim 1 , wherein the counterweight assembly includes at least one counterweight bracket defining a counterweight bracket opening extending therethrough.

7. The modular battery system of claim 6 , wherein the battery assembly includes a battery bracket defining a battery bracket opening extending therethrough.

8. The modular battery system of claim 7 , wherein a retention pin is configured to be inserted through the counterweight bracket opening and the battery bracket opening to secure the battery assembly to the counterweight assembly.

9. The modular battery system of claim 1 , wherein each of the pair of channels includes at least one spacer attached to a laterally-outer surface thereof, and wherein each of the at least one spacers is configured to add additional counterweight to the battery assembly.

10. The modular battery system of claim 1 , wherein the battery assembly includes a plurality of battery assembly openings arranged in a predefined pattern, and wherein each of the pair of channels include a plurality of channel openings arranged to conform to at least a portion of the predefined pattern defined by the plurality of battery assembly openings.

11. A modular battery system for a material handling vehicle, the modular battery system comprising:
a counterweight assembly;
a battery assembly enclosing a power source and including a battery base; and
a pair of channels removably coupled to the battery base and each including at least one spacer attached to a laterally-outer surface thereof, wherein the battery assembly is configured to be slidably installed onto the counterweight assembly, and wherein each of the at least one spacers is configured to add additional counterweight to the battery assembly.

12. The modular battery system of claim 11 , wherein the pair of channels are laterally separated from one another to define a counterweight slot therebetween.

13. The modular battery system of claim 12 , wherein the battery assembly is configured to be slidably installed onto the counterweight assembly with the counterweight assembly received within the counterweight slot defined between the pair of channels.

14. The modular battery system of claim 11 , wherein the battery assembly includes a plurality of battery assembly openings arranged in a predefined pattern, and wherein each of the pair of channels include a plurality of channel openings arranged to conform to at least a portion of the predefined pattern defined by the plurality of battery assembly openings.

15. The modular battery system of claim 11 , further comprising at least one roller bearing coupled to the counterweight assembly and configured to provide a rolling interface between the pair of channels and the counterweight assembly.

16. The modular battery system of claim 11 , wherein the counterweight assembly includes a central block protruding from a central base, and wherein the central block defines a first lateral surface and a second lateral surface.

17. The modular battery system of claim 16 , wherein the each of the first lateral surface and the second lateral surface includes at least two roller bearings that are longitudinally separated from one another.

18. The modular battery system of claim 17 , wherein each of the first lateral surface and the second lateral surface includes a first bearing spacer arranged longitudinally between the at least two roller bearings and a second bearing spacer arranged adjacent to a back side of the counterweight assembly.

19. The modular battery system of claim 11 , wherein the counterweight assembly includes at least one counterweight bracket defining a counterweight bracket opening extending therethrough, and wherein the battery assembly includes a battery bracket defining a battery bracket opening extending therethrough.

20. The modular battery system of claim 19 , wherein a retention pin is configured to be inserted through the counterweight bracket opening and the battery bracket opening to secure the battery assembly to the counterweight assembly.
