Abstract

A frame for a bike with a plurality of frame units coupled to each other, at least one of the plurality of frame units includes a hollow chamber, and a first partition wall that partitions the hollow chamber into a first chamber unit and a second chamber unit, wherein the first chamber unit includes an opening in a first side of the first chamber unit and an accommodation space to accommodate a battery pack, and wherein the second chamber unit includes a plurality of holes through a first side of the second chamber unit, an interior of the second chamber unit and an exterior of the frame for the bike being in fluid communication through the plurality of holes.

First claim

What is claimed is:

1. A frame for a bike, the frame comprising:
a hollow chamber; and
a first partition wall that partitions the hollow chamber into a first chamber unit and a second chamber unit, the first partition wall including a plurality of openings through which the second chamber unit is in fluid communication with the first chamber unit, wherein:
the first chamber unit includes an opening in a first side of the first chamber unit and an accommodation space to accommodate a battery pack, the first partition wall separating the accommodation space from the second chamber unit,
the second chamber unit includes at least one hole through a first side of the second chamber unit, an interior of the second chamber unit and an exterior of the frame for the bike being in fluid communication through the at least one hole,
the second chamber unit has a second side corresponding to the first partition wall, and
the second chamber unit has at least one rib that extends in a height direction of the second chamber unit, connecting the first side of the second chamber unit to the first partition wall, the at least one rib extending in a lengthwise direction of the second chamber unit, the second chamber unit being partitioned into a plurality of areas by the at least one rib.

2. The frame as claimed in claim 1 , comprising:
a first outer sidewall and a second outer sidewall that face each other; and
a third outer sidewall and a fourth outer sidewall that connect the first outer sidewall to the second outer sidewall and face each other, the hollow chamber being defined by the first through fourth outer sidewalls.

3. The frame as claimed in claim 1 , wherein each of the plurality of areas is in fluid communication with the exterior of the frame through the at least one hole.

4. The frame as claimed in claim 1 , wherein the first partition wall includes a plurality of openings through which each of the plurality of areas of the second chamber unit is in fluid communication with the first chamber unit.

5. The frame as claimed in claim 1 , further comprising a second partition wall that partitions the hollow chamber to include a third chamber unit, the first chamber unit being between the second chamber unit and the third chamber unit.

6. The frame as claimed in claim 5 , wherein the second partition wall is substantially parallel to the first partition wall and faces the first partition wall.

7. The frame as claimed in claim 6 , wherein a first sidewall of the first chamber unit having the opening therein is perpendicular to the first partition wall and the second partition wall.

8. The frame as claimed in claim 5 , wherein the third chamber unit includes at least one rib that extends in a lengthwise direction of the third chamber unit, the third chamber unit being partitioned into a plurality of areas by the at least one rib.

9. The frame as claimed in claim 8 , wherein the second partition wall includes a plurality of openings, the plurality of areas of the third chamber unit being in fluid communication with the first chamber unit through the plurality of openings.

10. The frame as claimed in claim 9 , wherein the third chamber unit includes a plurality of openings through which each of the plurality of areas and the exterior of the frame are in fluid communication with each other.

11. An electric bike, comprising:
a front wheel and a rear wheel;
a driving portion that drives the rear wheel;
an electromotion portion that is electrically connected to a battery pack, converts electric energy of the battery pack into kinetic energy, and drives at least one of the rear wheel and the driving portion; and
a frame, the frame including:
a hollow chamber; and
a first partition wall that partitions the hollow chamber into a first chamber unit and a second chamber unit, the first partition wall including a plurality of openings through which the second chamber unit is in fluid communication with the first chamber unit, wherein:
the first chamber unit includes an opening in a first side of the first chamber unit and an accommodation space to accommodate a battery pack, the first partition wall separating the accommodation space from the second chamber unit, and
the second chamber unit includes at least one hole through a first side of the second chamber unit, an interior of the second chamber unit and an exterior of the frame for the bike being in fluid communication through the at least one hole, the battery pack being in the accommodation space.

12. The electric bike as claimed in claim 11 , wherein the opening faces away from a ground, the second chamber unit being adjacent to the ground.

13. The electric bike as claimed in claim 11 , wherein the frame further comprises a third chamber unit, the first chamber unit being between the second chamber unit and the third chamber unit.

14. The electric bike as claimed in claim 13 , wherein the first chamber unit and the third chamber unit are adjacent to each other, a second partition wall being between the first chamber unit and the third chamber unit, and the third chamber unit including at least one rib extending in a lengthwise direction of the third chamber unit.

15. The electric bike as claimed in claim 14 , wherein the third chamber unit is partitioned into a plurality of areas by the at least one rib, and the second partition wall includes a plurality of holes through which the plurality of areas of the third chamber unit and the first chamber unit are fluidically connected to each other.

16. The electric bike as claimed in claim 11 , wherein the first chamber unit and the second chamber unit are adjacent to each other, the first partition wall being between the first chamber unit and the second chamber unit, and the second chamber unit including at least one rib extends in a lengthwise direction of the second chamber unit.

17. The electric bike as claimed in claim 16 , wherein the second chamber unit is partitioned into a plurality of areas by the at least one rib, and the second chamber unit includes holes corresponding to the plurality of areas and through which each of the plurality of areas is fluidically connected to the exterior of the frame.

18. A frame for a bike, the frame comprising:
a hollow chamber; and
a first partition wall that partitions the hollow chamber into a first chamber unit and a second chamber unit, the first partition wall including a plurality of openings through which the second chamber unit is in fluid communication with the first chamber unit; and
a second partition wall that partitions the hollow chamber to include a third chamber unit, the first chamber unit being between the second chamber unit and the third chamber unit, wherein:
the first chamber unit includes an opening in a first side of the first chamber unit and an accommodation space to accommodate a battery pack, the first partition wall separating the accommodation space from the second chamber unit,
the second chamber unit includes at least one hole through a first side of the second chamber unit, an interior of the second chamber unit and an exterior of the frame for the bike being in fluid communication through the at least one hole, and
the third chamber unit includes at least one rib that extends in a lengthwise direction of the third chamber unit, the third chamber unit being partitioned into a plurality of areas by the at least one rib.
