초록 ▼

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.

1. A children's ride-on vehicle, comprising:a reduced scale body having a passenger region with a seat configured to accommodate at least one child; a plurality of wheels rotatably coupled to the body and including a drive wheel and a steerable wheel; a steering assembly having a steering mechanism positioned for operation by a child sitting on the seat, wherein the steering assembly is coupled to the steerable wheel; a drive assembly including the drive wheel and a battery powered motor assembly with a motor output; and a torque attenuation system configured to regulate the transmission of torque from the motor assembly to the drive wheel, wherein the torque attenuation system includes a force reducing mechanism adapted to receive a rotational input from the motor output and regulate the transmission thereof to the drive wheel and a motor output linkage rotationally coupled to the motor output and adapted to transmit the rotational input from the motor output to the force reducing mechanism, wherein the torque attenuation system is adapted to interrupt the transmission of the rotational input to the drive wheel when a torque threshold is exceeded by an applied torque from the motor output, wherein the force reducing mechanism includes a drive member, a driven member and a resilient member; wherein the transmission of the rotational input is caused by engagement of the drive member and the driven member, wherein the resilient member is configured to exert an engaging force to bias the drive member and the driven member together to rotate as a unit, wherein the drive member includes a drive member engagement portion that includes a drive detent structure and the driven member includes a driven member engagement portion that includes a driven detent structure configured to engage the drive detent structure; and further wherein the drive member engagement portion is configured to couple with the driven member engagement portion for rotation as a unit when the torque threshold is not exceeded, wherein the torque attenuation system is configured to respond to an applied torque from the motor output having a magnitude that exceeds the torque threshold by applying a disengaging force to oppose the engaging force and thereby deform the resilient member and disengage the drive member and driven member for rotation independent of one another, and further wherein the torque attenuation system is configured to respond to a subsequent reduction in the magnitude of the applied torque below the torque threshold by reducing the disengaging force so that the engaging force again biases the drive member and driven member together to rotate as a unit.
