Abstract: Light-duty box-type hydrogen fuel trucks are highly suitable for scenarios such as urban logistics and cold chain transportation. Benefiting from favorable current policies, large-scale demonstration operations have been launched in major regions of China. Therefore, balancing vehicle lightweighting and highlighting product performance differentiation has become a key focus in the design of such models. This paper proposes a solution to the aforementioned challenges by adopting integrated layout of vehicle components, utilizing new products (high-voltage integrated cooling fans, 70 MPa hydrogen cylinders), and implementing differentiated product functions for cargo boxes. Additionally, based on the comprehensive analysis of component failure rates, the layout positions of vehicle parts are optimized to address prominent after-sales issues in the current market, such as high maintenance difficulty and prolonged operation time.

Key words: light-duty box-type hydrogen fuel truck; new energy light commercial truck; vehicle chassis integrated arrangement
