The invention discloses vehicle-mounted hydrogen supply equipment. The equipment comprises a hydrogen storage module and a hydrogen supply module, the hydrogen storage module comprises a plurality ofhydrogen cylinders and a support assembly, the hydrogen supply module comprises a plurality of pipeline assemblies and valve assemblies, the hydrogen cylinders are connected with the valve assembliesthrough the pipeline assemblies, and the hydrogen cylinders are connected to the support assembly through hoops. By adopting aluminum alloy, GFRP or CFRP material for integrated frame design, the weight of the vehicle-mounted hydrogen supply system with the same hydrogen storage capacity can be reduced by 11.4-36.8%; PRD vent nozzles and needle valve vent nozzles are integrally designed, so the number of the vent nozzles of the vehicle-mounted hydrogen supply system is reduced to two; and in order to facilitate transportation and installation, the vehicle-mounted hydrogen supply system is divided into two sub-assemblies, a hydrogen concentration sensor is arranged at the end, close to the integrated cylinder valves, between the two sub-assemblies, and a hydrogen concentration sensor is arranged above the pressure reducing valve, so that the safety of the system is improved. A good using effect is achieved.

    本发明公开了一种车载供氢设备,它包含有储氢模块和供氢模块,所述储氢模块包含有若干氢瓶和支架总成,供氢模块包含有若干管道组件和阀门组件,氢瓶通过管道组件和阀门组件连接,氢瓶通过卡箍连接到支架总成上。通过采用铝合金、GFRP或CFRP材料进行集成框架设计,同样储氢量的车载供氢系统可实现减重11.4%~36.8%;PRD放空口与针阀放空口集成设计,车载供氢系统放空口数量减至2个;为便于运输、安装,将车载供氢系统分为两个分总成设计,并在两个分总成中间靠近集成瓶阀一端设置一个氢浓度传感器,在减压阀上方设置一个氢浓度传感器,提高系统安全性。取得了很好的使用效果。
