Abstract

An improved battery for children'"'"'s ride-on vehicles. The battery includes a sealed housing that contains an internal circuit breaker that disconnects the flow of energy from the battery to the vehicle'"'"'s one or more motors upon actuation. Upon removal of the actuating event, the circuit breaker automatically resets to reestablish the electrical circuit connecting the battery and the vehicle'"'"'s one or more motors. The battery may alternatively include a manual reset that is accessible external the housing. Additionally, the battery may also include an internal one-shot fuse to protect against catastrophic failure of the battery.

Claims

1. A children'"'"'s ride-on vehicle, comprising:

a body having a seat sized to accommodate a child;

a plurality of wheels;

a steering assembly adapted to selectively steer at least one of the plurality of wheels;

at least one electrically powered motor adapted to rotatably drive at least one of the plurality of wheels; and

at least one battery adapted to provide power to the at least one motor and comprising;

a sealed housing;

a plurality of cells sealed within the housing and electrically connected together; and

a resettable circuit breaker sealed within the housing and electrically connected with the plurality of cells.

2. The vehicle of claim 1, wherein the circuit breaker is adapted to automatically reset.

3. The vehicle of claim 1, wherein the circuit breaker is adapted to be reset manually by a user.

4. The vehicle of claim 3, wherein each of the at least one batteries includes a manual reset accessible by a user external the housing and in communication with the circuit breaker sealed within the housing.

5. The vehicle of claim 1, wherein the circuit breaker is connected in series with the plurality of cells.

6. The vehicle of claim 5, wherein the circuit breaker is connected in series between a pair of the plurality of cells.

7. The vehicle of claim 5, wherein the circuit breaker is connected in series external a pair of the plurality of cells.

8. The vehicle of claim 5, wherein the plurality of cells includes at least a pair of cells, and further wherein the circuit breaker is connected in series between the pair of cells.

9. The vehicle of claim 1, wherein the body is at least substantially formed from plastic.

10. The vehicle of claim 1, wherein the vehicle is a reduced-scale version of a full-sized vehicle and is sized to be operated by a child.

11. The vehicle of claim 1, wherein each of the at least one batteries is a rechargeable battery.

12. The vehicle of claim 1, wherein housing includes a socket that is adapted to receive a plug to electrically connect the battery with the at least one motor.

13. The vehicle of claim 12, wherein the housing includes a socket that is adapted to receive a charging probe to electrically connect the battery with a charger.

14. The vehicle of claim 12, wherein the socket is adapted to selectively receive a plug to electrically connect the battery with the at least one motor and a charging probe to electrically connect the battery with a charger.

15. The vehicle of claim 1, further including a speed control adapted to selectively control the actuation of the at least one motor by the at least one battery.
