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

Abstract
Claims
1. A folding electric quadricycle, characterized in that, include: Vehicle base (1); The steering assembly (2) includes a steering shaft (21), a steering tube (22), a linkage plate (23), and a transmission rod (24). The vehicle body base (1) is provided with a connecting seat (11). The front end of the connecting seat (11) is provided with a fixed tube (12). The steering tube (22) is rotatably disposed in the fixed tube (12). The connecting seat (11) is provided with steering seats (112) at both ends. A pair of steering shafts (21) are respectively rotatably disposed in the steering seats (112). The linkage plate (23) is disposed at the bottom end of the steering tube (22). The linkage plate (23) is connected to the steering shaft (21) in a transmission connection. One end of the transmission rod (24) is connected to the linkage plate (23).
