Abstract

The present invention relates a battery tray where rechargeable batteries are received.
According to one aspect of the present invention, a battery tray where a plurality of rechargeable batteries are received is provided. The battery tray includes: a first support wall and a second support wall that are disposed facing each other; a third support wall and a fourth support wall disposed facing each other, which connect an end of the first support wall and an end of the second support wall to each other; and a partition connected to an inner side of the third support wall and an inner side of the fourth support wall, wherein a first interior undercut is provided in the first support wall, a second interior undercut is provided in the second support wall, and the first interior undercut and the second interior undercut are asymmetrically disposed with reference to the partition.

First claim

The invention claimed is:

1. A battery tray where a plurality of rechargeable batteries are received, the battery tray comprising:
a first support wall and a second support wall that are disposed facing each other;
a third support wall and a fourth support wall disposed facing each other, which connect an end of the first support wall and an end of the second support wall to each other; and
a partition extending between an inner side of the third support wall and an inner side of the fourth support wall,
wherein:
the first support wall includes a pair of first protrusions that protrude from the first support wall toward the second support wall, and a first interior undercut is provided in the first support wall between the first protrusions,
the second support wall includes a pair of second protrusions with a space therebetween, the pair of second protrusions being aligned with and protruding toward the pair of first protrusions, and a pair of second interior undercuts is provided in the second support wall, the pair of second protrusions and the space being interposed between the second interior undercuts,
the second support wall does not include an undercut in the space such that the first interior undercut and the second interior undercuts are asymmetrically disposed with reference to the partition, and
the partition extending between the inner side of the third support wall and the inner side of the fourth support wall includes at least one dual undercut that faces the first support wall, the dual undercut including a first concave groove and a second concave groove within the first concave groove such that an upper end of the second concave groove is lower than an upper end of the first concave groove, the second concave groove being more concave than the first interior groove, a bottom of the dual undercut protruding toward the second support wall.

2. The battery tray of claim 1 , wherein a third interior undercut is provided in the third support wall, a fourth interior undercut is provided in the fourth support wall, and the third interior undercut and the fourth interior undercut are symmetrical to each other with reference to a virtual line that perpendicularly passes the partition at the center of the partition.

3. The battery tray of claim 2 , wherein a pair of third interior undercuts is provided in the third support wall, and one of the pair of third interior undercuts is disposed between the first support wall and the partition, and the other of the pair of third interior undercuts is disposed between the second support wall and the partition.

4. The battery tray of claim 3 , wherein a pair of fourth interior undercuts is provided in the fourth support wall, and one of the pair of fourth interior undercuts is disposed between the first support wall and the partition, and the other of the pair of fourth interior undercuts is disposed between the second support wall and the partition.

5. The battery tray of claim 1 , wherein the pair of first protrusions partitions spaces where batteries are inserted.

6. The battery tray of claim 5 , wherein:
a pair of third protrusions is provided in sides of the partition to face the pair of first protrusions, and
the at least one dual undercut includes a first center dual undercut provided between one of the pair of third protrusions, and the third support wall, and a second center dual undercut provided between the other of the pair of third protrusion and the fourth support wall.

7. The battery tray of claim 6 , wherein:
a support groove, configured to receive a bottom of a first center dual undercut of another identical battery tray that is stacked above, is provided in an upper portion of the first center dual undercut, and
another support groove, configured to receive a bottom of a second center dual undercut of the other identical battery tray stacked above, is provided in an upper portion of the second center dual undercut.

8. The battery tray of claim 6 , wherein the pair of second protrusions partitions spaces where batteries are inserted, and one of the pair of second interior undercuts is disposed between one of the pair of second protrusions and the third support wall, and the other of the pair of second interior undercuts is disposed between the other of the pair of second protrusions and the fourth support wall.

9. The battery tray of claim 8 , wherein a pair of fourth protrusions that faces the pair of second protrusions is provided in a side of the partition that faces the second support wall, the pair of fourth protrusions having a third center dual undercut therebetween.

10. The battery tray of claim 9 , wherein a support groove, which is configured to receive a bottom of a third center dual undercut of another identical battery tray that is stacked above, is provided in an upper portion of the third center dual undercut.

11. The battery tray of claim 9 , wherein the third support wall, the fourth support wall, the first protrusions, the second protrusions, the third protrusions, and the fourth protrusions are each configured to contact side surfaces of batteries disposed in the battery tray.

12. The battery tray of claim 1 , wherein a third protrusion that faces one of the pair of first protrusions is provided in a side of the partition, which faces the first support wall, and a center dual undercut is provided between the third protrusion and the third support wall.

13. The battery tray of claim 12 , wherein a fourth protrusion that faces one of the pair of second protrusions is provided in a side of the partition, which faces the second support wall, and a second center dual undercut is provided between the fourth protrusion and the fourth support wall.

14. The battery tray of claim 13 , wherein a support groove, which is configured to receive a bottom of a center dual undercut of another identical battery tray that is stacked above, is provided in an upper portion of the second center dual undercut.

15. The battery tray of claim 1 , wherein a plurality of center support grooves are provided in the partition, and the center support grooves are provided at upper ends of lateral sides of the partition and are asymmetrical to each other with reference to the center of the partition.

16. The battery tray of claim 1 , wherein the first support wall comprises a first interior wall and a first exterior wall, the first interior undercut is provided in the first interior wall, a plurality of first exterior dual undercuts are provided in the first exterior wall, and corner protrusions are provided in upper portions of the first exterior dual undercuts.

17. The battery tray of claim 16 , wherein the corner protrusions are connected from an upper surface of the first support wall to an upper surface of the third support wall.
