Abstract

A mechanical stabilization system for a battery assembly is disclosed. The system includes an actuator and a stabilizer that are configured to work in concert. The actuator and stabilizer are disposed in a housing of the battery assembly. The system may be implemented by depression of the actuator disposed in the housing, which causes the stabilizer to retract a support post into the housing. The depression can occur during a docking operation of the battery assembly with a lift mechanism for an electric vehicle. When the actuator is released, the support post automatically reverts to its previous, deployed state. The support post is configured to maintain the battery assembly in a stable configuration when the battery assembly is separated from the electric vehicle.

First claim

The invention claimed is:

1. A stabilization system for a battery assembly, the stabilization system comprising:
a housing including a forward portion, a rearward portion, a first side portion, a second side portion, and a bottom region;
a first stabilizer disposed in the forward portion, the first stabilizer including a first support post that extends distally outward from a first aperture formed in the bottom region;
a first actuator disposed in the rearward portion, where the first actuator is mechanically connected to the first stabilizer and the first actuator further includes a top portion that protrudes outward from the housing in the deployed configuration; and
wherein the first stabilizer is configured to retract the first support post in response to an actuation of the first actuator, thereby automatically transitioning the stabilization system from a deployed configuration to a retracted configuration.

2. The stabilization system of claim 1 , wherein the housing further includes an interior cavity configured to receive one or more battery packs.

3. The stabilization system of claim 1 , further comprising:
a second stabilizer disposed in the forward portion;
a second actuator disposed in the rearward portion, where the second actuator is mechanically connected to the second stabilizer; and
wherein the second stabilizer includes a second support post that, in the deployed configuration, extends distally outward from a second aperture formed in the bottom region.

4. The stabilization system of claim 1 , wherein:
the bottom region includes a sloped exterior surface along the forward portion and a substantially flat exterior surface along the rearward portion; and
the first support post, when deployed, has a length that causes a substantial entirety of the exterior surface along the rearward portion to remain in contact with a substantially flat ground surface, thereby providing stability to the battery assembly.

5. The stabilization system of claim 4 , wherein a distance between the ground surface and the sloped exterior surface region along the forward portion increases from a first distance near a central region of the battery assembly to a second distance further from the central region.

6. The stabilization system of claim 1 , wherein the first stabilizer further includes a hydraulic cylinder that, when extended, causes deployment of the first support post.

7. The stabilization system of claim 1 , wherein the first support post extends outward in a diagonal direction relative to a vertical axis when deployed.

8. The stabilization system of claim 1 , wherein the first support post has a substantially cylindrical three-dimensional shape.

9. The stabilization system of claim 1 , wherein actuation of the first actuator involves a depression of the top portion until the top portion is disposed within the housing.

10. The stabilization system of claim 9 , wherein the top portion is received by a base receptacle of the actuator when the top portion is depressed.

11. The stabilization system of claim 1 , wherein the top portion has a substantially cylindrical three-dimensional shape.

12. The stabilization system of claim 1 , wherein the first support post is disposed entirely within the housing when the stabilization system is in the retracted configuration.

13. A stabilization system for an electric vehicle, the stabilization system comprising:
a battery assembly including a housing, a first actuator, and a first stabilizer;
an electric vehicle including a lift mechanism, the lift mechanism configured to dock with the battery assembly; and
wherein the lift mechanism actuates the first actuator when the battery assembly docks with the lift mechanism, thereby causing a first support post of the first stabilizer to automatically transition from a deployed state to a retracted state, and the lift mechanism further includes a depressor, where the depressor is configured to contact an exposed top portion of the first actuator when the lift mechanism docks with the battery assembly.

14. The stabilization system of claim 13 , wherein the lift mechanism further includes two lift arms that move from an open configuration to a closed configuration during docking with the battery assembly, the two lift arms being closer to one another in the closed configuration than in the open configuration, which results in depression of the depressor.

15. The stabilization system of claim 13 , wherein the first support post is disposed entirely within the housing when the first actuator is actuated.

16. The stabilization system of claim 13 , wherein the battery assembly further comprises a second actuator and a second stabilizer, and actuation of the second actuator causes a second support post of the second stabilizer to retract into the housing.

17. The stabilization system of claim 13 , wherein separation of the battery assembly from the lift mechanism automatically releases the first actuator, causing the first support post of the first stabilizer to revert to the deployed state.

18. The stabilization system of claim 17 , wherein the battery assembly includes a sloped bottom surface, and the first support post extends outward from an opening in the sloped bottom surface in the deployed state, thereby preventing the battery assembly from tipping.

19. The stabilization system of claim 13 , wherein the depressor includes a base with a smooth lower surface that is substantially aligned with a horizontal plane, and the lower surface contacts the exposed top portion during docking.

20. The stabilization system of claim 13 , wherein the depressor is disposed directly adjacent to an engagement assembly of the lift mechanism.
