On July 10, Xiaomi Auto Technology Co., Ltd. achieved a significant milestone by being awarded a utility model patent for its groundbreaking “Underwater Propeller and Transportation Vehicle.” This patent presents a solution to common challenges faced by traditional underwater propellers, such as excessive noise and rapid thrust degradation. It achieves this through the adoption of an ingenious annular flow channel design, which comprises an outer casing and an internal flow guide section. In terms of English expression habits, “achieved a significant milestone” is more vivid than “was granted” to describe the act of getting a patent. And “groundbreaking” is added to emphasize the innovative nature of the product. This innovative design effectively reduces noise levels, minimizes drag loss, boosts thrust, and prolongs the lifespan of the propeller blades. Moreover, the propeller incorporates a specialized mounting structure that seamlessly integrates with the underside of a vehicle. This feature makes it highly suitable for onboard waterborne travel scenarios, hinting at Xiaomi's ambitious exploration into the realm of amphibious transportation.
