Group 1 - The core point of the article is that Xiaomi Automotive Technology Co., Ltd. has recently published a patent for a "semi-cage roll bar and vehicle," which aims to enhance passenger safety during roll-over situations [1] Group 2 - The patent describes a semi-cage roll bar that includes a first support frame installed at the B-pillar position of the vehicle, providing support between the B-pillar, the vehicle's roof assembly, and the vehicle's floor assembly [1] - A second support frame extends downward and rearward from the first support frame, connecting to the vehicle body, which allows for the overall installation of the roll bar without occupying the A-pillar and front compartment area, ensuring passenger comfort [1] - The design features a triangular support structure formed by the second support frame, which effectively enhances the overall strength of the roll bar, preventing the collapse of the B-pillar and the vehicle's top structure during roll-over conditions, thus providing comprehensive protection for passengers [1]
