[0002] In electric vehicle design, the seat bucket structure, as a core load-bearing component supporting the driver's weight, directly affects the vehicle's safety performance and service life due to its structural strength and fatigue resistance. Currently, most traditional electric vehicles use side panels and front panels spliced ​​together and directly fixed to the seat bucket body or frame. When the driver sits on the vehicle, the side panels are prone to plastic deformation and warping outwards due to insufficient support strength. Furthermore, during daily use, the side panels are easily scratched by external objects, causing paint chipping or even damage. This not only further reduces the support strength of the side panels but also makes replacing them inconvenient, requiring the entire seat bucket to be disassembled. Summary of the Invention:

[0003] The purpose of this utility model is to provide a seat bucket structure for electric vehicles, which reasonably optimizes the structure of the side shell plate. By adding a side protective cover, the wall thickness of the side shell plate is increased, thereby improving the overall support strength. Furthermore, in later maintenance, the replacement of the side protective cover does not require disassembling the entire seat bucket structure, which is more convenient.
