Abstract

A battery cell holder is disclosed. In one embodiment, the holder includes first and second outer frames respectively positioned at first and second sides of a plurality of battery cells arranged substantially parallel with each other, wherein the first and second sides are opposing each other, and wherein the outer frames comprise first and second outer fastening members, respectively. The cell holder may further include at least one inner frame disposed between the outer frames, wherein the at least one inner frame comprises a first inner frame adjacent to the first outer frame, wherein the first inner frame has first and second inner fastening members which are respectively formed at opposing sides thereof and have corresponding shapes with respect to each other. The first inner fastening member may be connected to the first outer fastening member.

First claim

What is claimed is:

1. A battery cell holder comprising:
first and second outer frames respectively comprising first and second outer fastening members; and
at least one inner frame placed between the first and second outer frames, wherein the at least one inner frame comprises a first inner frame adjacent to the first outer frame, wherein the first inner frame comprises first and second inner fastening members opposing each other, wherein the first inner fastening member is configured to be connected to the first outer fastening member such that the first inner frame and the first outer frame receive and hold a first group of battery cells,
wherein the second inner fastening member is configured to be connected to the second outer frame or an adjacent inner frame such that i) the first inner frame and ii) the second outer frame or the adjacent inner frame receive and hold a second group of battery cells different from the first group of battery cells,
wherein the first inner frame includes i) a battery cell accommodating portion having a curved shape conforming to the shape of the outer surface of each of the battery cells and configured to accommodate part of each of the first and second groups of battery cells and ii) a pair of coupling portions formed on opposing ends of the battery cell accommodating portion, wherein each of the coupling portions includes a body extending perpendicularly to the battery cell accommodating portion, and first and second ends formed on opposing ends of the body and perpendicular to the body, wherein the first inner fastening member is formed on each of the first and second ends of the coupling portions so as to face the first outer frame, wherein the second inner fastening member is formed on each of the first and second ends of the coupling portions so as to face the second outer frame and wherein the body is narrower than the first and second ends of each coupling portion.

2. The cell holder according to claim 1 , wherein the shape of the first outer fastening member is identical to that of the second inner fastening member.

3. The cell holder according to claim 1 , wherein one of the first inner fastening member and the first outer fastening member is a latching groove, and wherein the other of the first inner fastening member and the first outer fastening member is a hook that is configured to be inserted and fastened to the latching groove.

4. The cell holder according to claim 1 , wherein the at least one inner frame further comprises a second inner frame adjacent to the second outer frame, wherein the second inner frame comprises first and second sides opposing each other and respectively including first and second inner fastening members, and wherein the second inner fastening member of the second inner frame is configured to be connected to the second outer fastening member.

5. The cell holder according to claim 4 , wherein one of the second inner fastening member and the second outer fastening member is a latching groove, and wherein the other of the second inner fastening member and the second outer fastening member is a hook that is configured to be inserted and fastened to the latching groove.

6. The cell holder according to claim 1 , wherein each of the battery cells has a cylindrical or prismatic shape.

7. The cell holder according to claim 1 , further comprising:
an additional outer frame; and
a first connecting rod formed on at least one side of each of the outer frames and coupled to the additional outer frame.

8. The cell holder according to claim 7 , wherein the additional outer frame has a first connection rod, and wherein the outer frame has a first connection groove into which the first connection rod is inserted.

9. The cell holder according to claim 8 , further comprising:
a second connection rod formed on at least one side of the inner frame and coupled to the adjacent inner frame.

10. The cell holder according to claim 1 , wherein the inner frame further comprises a mounting part in which battery cells in at least one column are positioned.

11. The cell holder according to claim 10 , wherein the mounting part is configured to surround at least a portion of the battery cells.

12. The cell holder according to claim 1 , wherein the battery cells are arranged in M rows and N columns, and wherein the inner and outer frames are configured to receive and hold K battery cells to satisfy the equation of M×N=K.

13. A battery cell holder comprising:
first and second outer frames spaced apart and comprising first and second outer fastening members, respectively; and
a plurality of inner frames placed between the first and second outer frames, wherein the inner frames comprise a first inner frame adjacent to the first outer frame, wherein the first inner frame comprises first and second inner fastening members opposing each other,
wherein the first inner fastening member is configured to be connected to the first outer fastening member such that the first inner frame and the first outer frame receive and hold a first group of battery cells,
wherein the second inner fastening member is configured to be connected to the second outer frame or an adjacent inner frame such that i) the first inner frame and ii) the second outer frame or the adjacent inner frame receive and hold a second group of battery cells different from the first group of battery cells,
wherein the first inner frame includes i) a battery cell accommodating portion having a curved shape conforming to the shape of the outer surface of each of the battery cells and configured to accommodate part of each of the first and second groups of battery cells and ii) a pair of coupling portions formed on opposing ends of the battery cell accommodating portion, wherein each of the coupling portions includes a body extending perpendicularly to the battery cell accommodating portion, and first and second ends formed on opposing ends of the body and perpendicular to the body, wherein the first inner fastening member is formed on each of the first and second ends of the coupling portions so as to face the first outer frame, wherein the second inner fastening member is formed on each of the first and second ends of the coupling portions so as to face the second outer frame, and wherein the body is narrower than the first and second ends of each coupling portion.

14. The cell holder according to claim 13 , wherein the shape of the first outer fastening member is identical to that of the second inner fastening member.

15. The cell holder according to claim 13 , wherein one of the first inner fastening member and the first outer fastening member is a latching groove, and wherein the other of the first inner fastening member and the first outer fastening member is a hook that is configured to be inserted and fastened to the latching groove.

16. The cell holder according to claim 13 , wherein the inner frames further comprise a second inner frame adjacent to the second outer frame, wherein the second inner frame comprises first and second sides opposing each other and respectively including first and second inner fastening members, and wherein the second inner fastening member of the second inner frame is configured to be connected to the second outer fastening member.
