    • A braking system for a stroller includes: a brake pedal positioned near a first rear wheel of the stroller; a braking cam operationally coupled to the brake pedal and rotatable around a pivot point from a first position to a second position; and a brake lever having a first end configured to contact the braking cam when the braking cam is in the second position, and a second end having a plurality of teeth configured to engage at least one gear driven by the first rear wheel of the stroller when the braking cam is in the second position. A depression of the brake pedal causes the braking cam to rotate around the pivot point from the first position to the second position, thereby causing the teeth of the brake lever to engage the at least one gear to prevent rotation of the first rear wheel.
    • 一种用于婴儿车的制动系统,包括:制动踏板,其位于婴儿车的第一后轮附近; 制动凸轮可操作地联接到所述制动踏板并且可围绕枢转点从第一位置转动到第二位置; 以及制动杆,其具有构造成当制动凸轮处于第二位置时与制动凸轮接触的第一端,并且具有多个齿的第二端构造成与由婴儿车的第一后轮驱动的至少一个齿轮接合, 制动凸轮处于第二位置。 制动踏板的下压使得制动凸轮围绕枢转点从第一位置旋转到第二位置,从而使制动杆的齿与至少一个齿轮接合,以防止第一后轮旋转。
