The invention belongs to the technical field of vehicle-mounted hydrogen cylinders, and particularly relates to a vehicle-mounted liquid hydrogen cylinder supporting structure. The structure comprises an outer bottle and an inner bottle, the inner bottle is installed in an inner cavity of the outer bottle, first hoops are fixedly installed on the two sides of the top of the inner cavity of the outer bottle, second hoops are fixedly installed on the two sides of the bottom of the inner cavity of the inner bottle, and the first hoops and the second hoops which correspond to each other up and down are fixed through bolts and nuts. A heat preservation layer is arranged between the inner bottle and the outer bottle, the heat preservation effect can be effectively improved through a double-layer vacuum heat preservation plate layer, a heat preservation cotton layer and a polystyrene plate layer, and therefore the low-temperature environment is kept; and meanwhile, the vacuum degree is monitored through a vacuum sensor, and when the vacuum degree is lower than a preset value, vacuumizing can be automatically conducted again, so that a relatively high vacuum degree is guaranteed, the heat preservation effect can be further achieved, the influence of external factors on fuel in the inner bottle is greatly reduced, the evaporation capacity is reduced, and energy is saved.
本发明属于车载氢气瓶技术领域,具体为一种车载液氢气瓶支撑结构,包括外瓶和內瓶,所述外瓶的内腔安装有內瓶,所述外瓶的内腔顶部两侧均固定安装有第一抱箍,所述內瓶的内腔底部两侧均固定安装有第二抱箍,上下对应的所述第一抱箍和第二抱箍通过螺栓和螺母固定。本发明內瓶和外瓶之间设置的保温层,利用双层真空保温板层以及保温棉层和聚苯乙烯板层能够有效的提升了保温的效果,从而保持低温环境,同时利用真空传感器监测真空度,使得能够在真空度低于预设值时,自动再次抽真空,从而保证相对较高的真空度,从而能够进一步起到保温的效果,进而大大降低了外界接因素对內瓶内燃料的影响,从而减少了蒸发量,节约了能源。
