Abstract

There is provided a non-stop battery changing system that includes: a body connected to a moving body that is moved by power, having a seat on a side, and having locking grooves and a power terminal in the seat; a battery pack inserted in the seat of the body to supply power to the moving body, having locking protrusions sliding inward/outward, and having a battery terminal that comes in contact with the power terminal; and a pushing protrusion extending outward from a side of the battery pack in a mounting direction of the battery pack inserted in the seat by movement of the moving body, and unlocking the locking protrusions out of the locking grooves, when the battery pack used in the seat is replaced with another charged battery pack.

First claim

What is claimed is:

1. A non-stop battery changing system comprising:
a body connected to a moving body that is moved by power, having a seat on a side that is open in the movement direction of the moving body, and having locking grooves and a power terminal in the seat;
a battery pack inserted in the seat of the body to supply power to the moving body, having locking protrusions sliding inward/outward to be locked/unlocked in/out of the locking grooves, and having a battery terminal that comes in contact with the power terminal; and
a pushing protrusion extending outward from a side of the battery pack in a mounting direction of the battery pack inserted in the seat by movement of the moving body, and unlocking the locking protrusions out of the locking grooves, when the battery pack used in the seat is replaced with another charged battery pack,
wherein the power terminal has a power anode and a power cathode arranged horizontally and spaced from each other,
the battery terminal has a battery anode and a battery cathode arranged horizontally, spaced from each other, and coming in contact with the power anode and the power cathode, respectively,
the power cathode, the battery anode, and the battery cathode extend in the mounting direction of the battery pack, and
the power anode has a first connection electrode and a second connection electrode spaced from each other in the mounting direction of the battery pack, and
wherein the power anode further has a power connection electrode, which is electrically connected with the first connection electrode, the second connection electrode, and the moving body, and diodes between the first connection electrode and the second connection electrode that are connected with the power connection electrode.

2. The system of claim 1 , wherein the locking protrusions are formed on a side and the other side of the battery pack, and
the locking grooves are formed on an end and the other end of the body.

3. The system of claim 2 , wherein the locking protrusions have the shape of a bar, slide perpendicular to the mounting direction of the battery pack, and are elastically supported by springs.

4. The system of claim 1 , wherein the locking protrusions have the shape of a bar, slide perpendicular to the mounting direction of the battery pack, and are elastically supported by springs.

5. The system of claim 1 , wherein the length of the battery anode is larger than the distance between the first connection electrode and the second connection electrode.

6. The system of claim 1 , wherein the length of the power cathode is larger than the sum of the length of the battery anode and the length of the first connection electrode or the length of the second connection electrode of the power anode.

7. The system of claim 1 , wherein the length of the battery pack is smaller than the sum of the length of the battery anode and the length of the power cathode.

8. The system of claim 1 , wherein a protrusion groove corresponding to the pushing protrusion is formed at the other end of the battery pack, and
the battery pack has:
triggers sliding perpendicular to the mounting direction of the battery pack;
a pair of pressing springs elastically supporting the triggers such that longitudinal free ends of the triggers protrude over the protrusion groove; and
link mechanisms unlocking the locking protrusions out of the locking grooves by being operated by the triggers that are pushed when the pushing protrusion is inserted into the protrusion groove.

9. The system of claim 8 , wherein the link mechanism is an assembly of a rack and a pinion.

10. The system of claim 8 , wherein the link mechanism moves the trigger and the locking protrusion in opposite direction.

11. The system of claim 1 , wherein both ends of the body are bent down, and holding portions are horizontally bent from the edges of the bending ends of the body.

12. The system of claim 1 , wherein the pushing protrusion has the shape of a wedge having a triangular edge.
