Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to an active and separable telescopic rear end. Background Art

[0002] As the automotive industry continues to evolve, consumers' expectations for vehicle performance are rising. They demand excellent maneuverability and flexible space adaptability in urban driving conditions, while also expecting excellent energy efficiency and driving stability at highway speeds. However, the body structure design of traditional vehicles is relatively fixed, especially the rear end, whose shape and dimensions remain largely unchanged after the vehicle is manufactured. This fixed structure presents significant drawbacks when adapting to varying driving conditions.

[0003] At high speeds, the fixed shape of the rear end of a vehicle easily creates turbulence and eddies in the airflow passing over it, resulting in significant air resistance. This not only significantly increases fuel consumption for gasoline-powered vehicles but also severely impacts the range of electric vehicles, limiting their competitiveness in long-distance driving. Furthermore, high wind resistance negatively impacts vehicle stability, making maneuvering more difficult and dangerous. In urban environments, where vehicles often need to navigate narrow streets and park, a fixed-length rear end can sometimes be inflexible, impacting vehicle maneuverability and space efficiency.

[0004] Therefore, it is necessary to design a rear end that can dynamically adjust the length and shape of the rear end under different driving conditions to reduce wind resistance and improve the vehicle's handling and space utilization efficiency. Utility Model Content
