The Xiaomi SU7, the company's first car, was very good at first, taking on the best electric cars and beating them in numbers. Although its format is very similar to this and that, the bad tongues accuse Chris Bangle's work of copying. But there's always a lot of work and patents behind them, which should not be forgotten. Xiaomi is not idle, already designing the components for the next car. This will include a hidden mechanical door handle.
According to the patent document, all side door openings in a car require the use of door handles, which can be opened by pulling the door handle. The door handles can be divided into convex, semi-concealed and concealed door handles, of which concealed door handles can reduce the drag of the entire car.
A concealed retractable door handle requires space to accommodate the handle retraction. After the handle retraction, another space is created that is completely independent of the handle retraction envelope. The corresponding structure for opening the car door is set upwards in this space. The car door can be opened by operating the appropriate mechanism in this space, i.e. the concealed retractable handle solution shall be provided with two independent spaces and the design solution shall be made electrical. Fold the handle to retract, making the overall structure complex, high cost and heavy weight.
The patent abstract shows that the patented concealed mechanical door handle eliminates the need for an electrically operated assembly. It allows automatic resetting of the concealed position of the handle assembly, is simple in construction, reduces weight while reducing cost, and is more convenient to operate.
I have written before about Xiaomi about patents, which was created by the Xiaomi SU7 electric car echoes back. The new door handle patent could be a component of a future Xiaomi car, reducing not only weight and drag, but also cost. The Xiaomi SU7 has one of the best features in terms of air resistance and if they want to reduce it, where else can they go?
