Based on the provided white-background product images, generate a poster explaining the structure of a children's protective helmet. The background features a warm off-white paper-like background, accented with subtle circular relief shadows. The upper left uses a thick dark brown sans-serif line titled "Multi-layer Protection / Safe Travel," while the upper right corner retains only a simple "Multiple Protection Structure" small round seal, without the certification standard or year. The middle section features a light ivory shell, a dark gray buffer layer, a black inner frame, and a bottom webbing to create a vertical layered exploded view, with uniform spacing between layers for clear structural clarity.
On the left, from top to bottom, five sections are connected by thin horizontal lines: "Wear-resistant shell," "Cushioning inner layer," "Wrap-around lining," "Breathable soft pad," "Adjustable strap"; Each paragraph has a black subheading and a line of gray-brown explanation. It retains the helmet's rounded shell, lining, knobs, webbing, and red safety buckle, with adjustable ventilation holes, interlayer profiles, and buckle shapes. No brand information, no new brand or slogan. The font is solid and clear, with titles and structure that do not overlap; Do not use the original logo, national standard certification, size parameters, footnotes, watermarks, or screenshot edges.
