The invention discloses a chassis arrangement structure of a fuel hydrogen extended range type electric logistics vehicle, two parallel longitudinal beams and a plurality of cross beams form a frame, the front part and the rear part of the frame are equal in width, and the front end of the frame is positioned below a cab. According to the arrangement structure, an industrial hydrogen cylinder serves as a hydrogen storage device, and the industrial hydrogen cylinder and a high-voltage distribution box are placed between two longitudinal beams side by side and fixed to a vehicle frame in a suspended mode; a free piston power generation device is adopted as a range extender, and the free piston power generation device and a range extender controller are arranged at the upper position of the rear end of a frame together. The super capacitor stores power generation energy of the range extender and is arranged below the front cabin and the cab. The free piston power generation device has the advantages that the industrial hydrogen cylinder is convenient to disassemble, hydrogenation is convenient, and due to the fuel universality of the free piston power generation device, the hydrogen cylinder can be replaced with other gas fuel; the range extender is arranged at the rear end of the vehicle frame, a large space is provided for a front cabin of the logistics vehicle, arrangement is reasonable, heat dissipation is facilitated, and the driving comfort is improved.
本发明公开了一种燃用氢气增程式电动物流车的底盘布置结构,两根平行纵梁以及若干横梁组成了车架,车架前后等宽,前端位于驾驶室下方。该布置结构将工业氢气瓶作为储氢装置,与高压配电盒并排摆放于两根纵梁之间,与车架悬置固定;采用自由活塞发电装置作为增程器,和增程器控制器一起置于车架后端偏上的位置;超级电容储存增程器的发电能并被置于前舱,驾驶室下方。本发明优势在于工业氢气瓶便于拆卸,加氢方便,且由于自由活塞发电装置的燃料普适性,可以将氢气瓶更换为其他气体燃料;增程器置于车架后端,为物流车前舱提供了大量空间,布置合理,便于散热且提高了驾驶的舒适性。
