摘要： A children's ride-on vehicle with a reduced scale chassis having a seat configured to accommodate at least one child. The vehicle further includes a drive assembly, which includes one or more drive wheels and a battery powered motor assembly. The battery powered motor assembly includes a motor output and a torque attenuation system, which is configured to regulate the transmission of torque from the motor assembly to the one or more drive wheels. The torque attenuation system incorporates a force reducing mechanism adapted to receive a rotational input from the motor output and regulate the transmission of that rotational input to the one or more drive wheels. In some embodiments of the invention, the torque attenuation system is a self-contained system, and in some embodiments of the invention, the torque attenuation system is adapted to be retrofit on existing children's ride-on vehicles.

摘要： Children's ride-on vehicles having improved motor assemblies. The vehicles are reduced-scale vehicles, often formed substantially from molded plastic, that are sized for use by children and which include battery-powered motor assemblies. The vehicles may include a noise-suppression device that is adapted to reduce electromagnetic noise, a cutoff device that is adapted to selectively restrict operation of the motor assembly, or both devices. In some embodiments, the cutoff device may be a temperature-sensitive cutoff device and/or a current-sensitive cutoff device. In some embodiments, the device is disposed within a motor housing provided with the vehicle.

摘要： 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).
