Children's ride-on vehicle charging assemblies with back feed protection
First Claim
1. A children'"'"'s ride-on vehicle assembly, comprising:
- a children'"'"'s ride-on vehicle, comprising;
a body having at least one seat sized for a child;
a plurality of wheels rotatably coupled to the body, wherein the plurality of wheels includes at least one driven wheel and at least one steerable wheel;
a steering assembly comprising a steering mechanism adapted to receive steering inputs from a child sitting on the at least one seat, and a steering linkage adapted to convey the steering inputs to the at least one steerable wheel;
a drive assembly adapted to selectively drive the rotation of the at least one driven wheel, wherein the drive assembly comprises;
a motor assembly comprising at least one electric motor,a speed control assembly, anda battery assembly adapted to selectively energize the motor assembly and including at least one rechargeable battery anda charging connection electrically connected to the at least one rechargeable battery; and
a battery charging assembly, comprising;
an adapter body configured to convert a source current to a charging current suitable to charge the at least one battery;
a charger cord extending from the adapter body and terminating within a charging connector housing, wherein the charging connector housing is configured to directly engage the charging connection of the battery assembly to establish an electrical connection between the adapter body and the at least one battery; and
at least one protective element configured to reduce backflow current from the battery assembly in the entirety of the charger cord, wherein the at least one protective element is enclosed within the charging connector housing.

Abstract
Battery charging assemblies for children'"'"'s ride-on vehicles, and children'"'"'s ride-on vehicles that include the same. The charging assemblies may include a power adapter that is adapted to be electrically connected to a power source, a charger cord, and a charging connector that is adapted to electrically interconnect with the rechargeable battery of the ride-on vehicle. The battery charging assemblies further include at least one protective element to prevent or significantly reduce backflow current from the battery into the battery charging assembly. The protective element may be located in the charging probe or at any point along the charger cord of the battery charging assembly. The protective element may include any suitable current-limiting or current-interrupting device. Examples of such current limiting devices include, without limitation, a fuse, a circuit breaker, an anti-backflow diode, and a resettable fuse such as a positive temperature coefficient resistor (PTC resistor).
