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

摘要： 箱式氢燃料轻卡高度契合城市物流、冷链运输等场景，且受当前有利的政策影响，目 前已在我国主要地区开展规模化示范运营，因此如何兼顾整车轻量化和突出产品性能差异成 为此类车型设计的重点。文章通过采用整车零部件的集成布置、新产品使用（高压集成散热 风扇、70 MPa 氢瓶等）以及针对货箱差异化的产品功能为解决上述问题提供一定思路，同时 根据产品零部件故障率综合考虑其整车布置位置，解决车辆售后维修难度大、操作时间长等 目前市场突出的问题。
