AI Technical Summary

Technical Problem

Traditional folding electric four-wheeled vehicles rely on electronic sensors or complex mechanical linkages for independent steering, resulting in high costs and easy wear. Furthermore, the connection method between the steering shaft and the vehicle base makes it difficult to balance steering flexibility and stability after folding.

Method used

The steering assembly includes a steering shaft, steering tube, and linkage plate. The linkage plate enables synchronous rotation of the two steering shafts, eliminating the need for complex linkages or gear transmissions. The transmission rod and reinforcing ribs are used to improve structural stability. Combined with the folding assembly, the vehicle's folding function is realized.

Benefits of technology

It reduces manufacturing costs and failure rates, avoids uneven tire wear and vehicle drift, and improves steering synchronization and vehicle folding stability.
