AI Technical Summary

⚠Technical Problem

Existing toy cars are structurally unstable when moving at high speeds, and are prone to loss of control, especially when turning. Unreasonable center of gravity design and steering mechanism design defects cause them to fail to travel along the expected trajectory, resulting in loss of control phenomena such as tipping over and tilting.

⚗Method used

It adopts a three-wheel drive synchronous transmission system, including a differential, shock absorber and bogie. The differential drives a transmission system consisting of an external gear ring, an internal gear ring and a mating gear. The power split design reduces friction loss. The steering system is directly driven by the second drive motor to the bogie. The shock absorber is independently connected to the wheel body from the bogie to ensure steering flexibility and stability.

🎯Benefits of technology

It improves the stability of toy cars during high-speed movement and turning, reduces power waste and wheel slippage, ensures smooth driving, quick steering response, and maintains a stable posture.

Abstract

This utility model discloses a three-wheel drive synchronous transmission toy car, specifically relating to the field of toy car technology. It includes a three-wheel drive vehicle, a front wheel frame, a rear wheel frame, and a differential. The three-wheel drive vehicle comprises a frame, a front wheel frame, and a rear wheel frame. The rear wheel frame is mounted at the rear end of the frame, and front wheel frames are mounted on both sides of the front of the frame. A differential is positioned between the two sets of front wheel frames. A shock absorber is mounted above the two sets of front wheel frames, and a bogie is mounted on the side of the shock absorber. The differential of this toy car adopts an adaptive design, reducing its size by 50% compared to traditional structures, thus improving its compatibility with the overall structure of the toy car. Its transmission system consists of a drive external gear ring, dual drive internal gear rings, and mating gears. Power is distributed through the meshing of the drive external gear ring with the connecting swing frame gear shaft, and through the mating gears on the upper and lower sides of the mating shaft.
