Abstract

A vacuum cleaner, a battery assembly and a charging stand are provided. The battery assembly may include a plurality of battery cells, and a battery cover configured to support the plurality of battery cells. The battery cover may include a plurality of partition walls, and each of the plurality of partition walls forms a plurality of cell chambers that accommodate each of the plurality of battery cells, respectively, and at least a portion of the plurality of partition walls are spaced apart from each other to form at least one separation chamber.

First claim

What is claimed is:

1 . A battery assembly, comprising:
a plurality of battery cells; and a battery cover configured to support the plurality of battery cells, wherein the battery cover includes a plurality of partition walls, and each of the plurality of partition walls forms a plurality of cell chambers that accommodate each of the plurality of battery cells, respectively, and at least a portion of the plurality of partition walls are spaced apart from each other to form at least one separation chamber.

2 . The battery assembly according to claim 1 , wherein the plurality of partition walls is configured to allow the plurality of battery cells to be arranged in a plurality of rows.

3 . The battery assembly according to claim 2 , wherein the plurality of partition walls includes a plurality of first partition walls that accommodates the plurality of battery cells in a first row, and a plurality of second partition walls that accommodates the plurality of battery cells in a second row.

4 . The battery assembly according to claim 3 , wherein one or more of the plurality of first partition walls are spaced apart from one or more of the plurality of second partition walls to form a first separation chamber between the plurality of first partition walls and the plurality of second partition walls.

5 . The battery assembly according to claim 4 , wherein at least one of at least a portion of each of the plurality of first partition walls is spaced apart from each other to form a second separation chamber, or at least a portion of each of the plurality of second partition walls is spaced apart from each other to form the second separation chamber, or at least a portion of each of the plurality of first partition walls and at least a portion of each of the plurality of second partition walls are spaced apart from each other to form the second separation chamber.

6 . The battery assembly according to claim 4 , wherein the battery cover includes one or more heat radiation holes that discharges heat from the first separation chamber.

7 . The battery assembly according to claim 1 , wherein the battery cover includes a plurality of heat radiation holes that discharges heat from each of the plurality of cell chambers.

8 . The battery assembly according to claim 2 , wherein the plurality of battery cells in one of the plurality of rows are arranged so that a direction of a first pole of a first battery cell is opposite to a direction of a first pole of a second battery cell.

9 . The battery assembly according to claim 2 , wherein a direction of a first pole of a first battery cell in a first row among the plurality of rows is opposite to a direction of a first pole of a second battery cell in a second row facing the first battery cell in the first row.

10 . The battery assembly according to claim 2 , further comprising a conductor that electrically connects the plurality of battery cells arranged in a same row among the plurality of rows, and a conductor that electrically connects two battery cells in two adjacent rows among the plurality of rows.

11 . The battery assembly according to claim 10 , wherein the conductor is coupled to at least one of the battery cover or the plurality of partition walls.

12 . The battery assembly according to claim 1 , further comprising a conductor that connects the plurality of battery cells, and a cell cap that covers one or more of both poles of each of the plurality of battery cells, wherein the conductor contacts one or more poles of the battery cells passed through the cell cap.

13 . The battery assembly according to claim 1 , further comprising a conductor that connects the plurality of battery cells, and a cell cap that covers one or more of both poles of each of the plurality of battery cells, wherein the conductor contacts one or more poles of the battery cells while being inserted into the cell cap.

14 . The battery assembly according to claim 1 , further comprising a battery management unit that manages a voltage of each of the plurality of battery cells, and an outer case that accommodates the battery management unit and the battery cover.

15 . The battery assembly according to claim 14 , wherein the outer case includes a partition plate that divides a first space that accommodates the battery cover from a second space that accommodates the battery management unit.

16 . The battery assembly according to claim 14 , wherein at least a portion of an internal surface of the outer case and the battery cover are spaced apart from each other to form a heat radiation path between the internal surface of the outer case and the battery cover.

17 . The battery assembly according to claim 14 , wherein the outer case includes a heat radiation hole that discharges internal heat from the outer case to outside the outer case.

18 . The battery assembly according to claim 17 , wherein the outer case further includes an opening and closing flap that opens and closes the heat radiation hole, and an elastic member that provides an elastic force to the opening and closing flap in a direction that the opening and closing flap closes the heat radiation hole.

19 . A vacuum cleaner, comprising:
a cleaner body having an energy consumption component operated by receiving power, and a battery installation module; a suction head configured to communicate with the cleaner body; and a battery assembly configured to supply the power to the energy consumption component, and separably provided at the battery installation module, wherein the battery assembly includes: a plurality of battery cells; and a battery cover configured to support the plurality of battery cells, the battery cover including a plurality of partition walls that forms a plurality of cell chambers that accommodates each of the plurality of battery cells, respectively.

20 . The vacuum cleaner according to claim 19 , further comprising a cover that covers the battery installation module, the cover including a heat radiation hole.

21 . The vacuum cleaner according to claim 20 , wherein the battery assembly further includes:
an outer case including a heat radiation hole that discharges internal heat from the outer case outside of the outer case; and an opening and closing flap that opens and closes the heat radiation hole, wherein the cleaner body includes a pressing part that operates the opening and closing flap while the battery assembly is installed at the cleaner body.

22 . A charging stand, comprising:
a charging stand body having a terminal connected to a terminal of a battery assembly; a pressing part provided at the charging stand body and configured to press an opening and closing flap to open and close a heat radiation hole of the battery assembly; and a heat radiation opening provided at the charging stand body and configured to communicate with the heat radiation hole of the battery assembly.
