Abstract

An unmanned vehicle includes a body and a plurality of battery packs. The battery packs are detachably stacked on the body, wherein the body sequentially uses the power of the battery packs in an anti-gravity direction.

First claim

What is claimed is:

1 . An unmanned vehicle, comprising:
a body; and a plurality of battery packs detachably stacked on the body, wherein the body sequentially uses a power of the plurality of battery packs in an anti-gravity direction.

2 . The unmanned vehicle according to claim 1 , wherein the plurality of battery packs are stacked on the body in an electromagnetically attractive manner, and at least one of the plurality of battery packs is unloaded from the body in a demagnetizing manner.

3 . The unmanned vehicle according to claim 2 , wherein each of the plurality of battery packs has a first surface and a second surface opposite each other, and each of the plurality of battery packs comprises an electromagnet pack and a magnetic structure pack, the electromagnet pack is disposed on the first surface, and the magnetic structure pack is disposed on the second surface.

4 . The unmanned vehicle according to claim 3 , wherein each of the plurality of battery packs further comprises a battery management module electrically connected to the electromagnet pack to activate or deactivate a magnetism of the electromagnet pack.

5 . The unmanned vehicle according to claim 4 , wherein the battery management module of one of the plurality of battery packs activates the magnetism of the electromagnet pack to electromagnetically attract the magnetic structure pack of another of the plurality of battery packs and is stacked on the body.

6 . The unmanned vehicle according to claim 4 , wherein the battery management module of one of the plurality of battery packs turns off the magnetism of the electromagnet pack to demagnetize the magnetic structure pack of another of the plurality of battery packs and is unloaded from the body.

7 . The unmanned vehicle according to claim 2 , wherein the magnetic structure pack comprises a plurality of magnets or a plurality of iron sheets.

8 . The unmanned vehicle according to claim 2 , wherein when the unmanned vehicle is in a desired charged state, a first battery pack of the plurality of battery packs stacked on the body and furthest away from the body is unloaded to expose a second battery pack, and the second battery pack is recharged by electromagnetically attracting at least one supplementary battery pack on a ground charging station to be stacked thereon.

9 . The unmanned vehicle according to claim 2 , wherein when the unmanned vehicle is in a desired charged state, a battery pack of the plurality of battery packs stacked on the body and furthest away from the body is recharged by electromagnetically attracting at least one supplementary battery pack on a ground charging station to be stacked thereon.

10 . The unmanned vehicle according to claim 9 , wherein when a power of the at least one supplementary battery pack is greater than a power of the battery pack, the at least one supplementary battery pack charges the battery pack.

11 . The unmanned vehicle according to claim 2 , wherein when the unmanned vehicle is in a desired charged state, a first battery pack of the plurality of battery packs stacked on the body and furthest away from the body is unloaded to expose a second battery pack, and the second battery pack is recharged by electromagnetically attracting at least one supplementary battery pack on an aerial charging station to be stacked thereon.

12 . The unmanned vehicle according to claim 2 , wherein when the unmanned vehicle is in a desired charged state, a battery pack of the plurality of battery packs stacked on the body and furthest away from the body is recharged by electromagnetically attracting at least one supplementary battery pack on an aerial charging station to be stacked thereon.

13 . The unmanned vehicle according to claim 12 , wherein when a power of the at least one supplementary battery pack is greater than a power of the battery pack, the at least one supplementary battery pack charges the battery pack.

14 . The unmanned vehicle according to claim 2 , wherein when the unmanned vehicle is in an emergency state, the at least one battery pack of the plurality of battery packs is unloaded from the body in a demagnetized manner.

15 . The unmanned vehicle according to claim 1 , wherein each of the plurality of battery packs has an assembly surface, and one of the plurality of battery packs is stacked on another of the plurality of battery packs in a manner parallel to the assembly surface.

16 . The unmanned vehicle according to claim 15 , wherein the plurality of battery packs have the same specifications.

17 . The unmanned vehicle according to claim 1 , wherein each of the plurality of battery packs has a plurality of contacts, and the plurality of contacts of one of the plurality of battery packs are electrically connected to the plurality of contacts of another of the plurality of battery packs.

18 . The unmanned vehicle according to claim 1 , wherein the plurality of battery packs comprise a first battery pack and at least one second battery pack, the first battery pack is assembled on the body, and the at least one second battery pack is detachably stacked on the first battery pack.

19 . The unmanned vehicle according to claim 18 , wherein the first battery pack comprises a built-in battery pack, and the at least one second battery pack comprises at least one disposable battery pack.

20 . The unmanned vehicle according to claim 1 , wherein each of the plurality of battery packs comprises a disposable battery pack.
