Description
Technical Field
[0001] This utility model relates to a layout structure of an on-board hydrogen storage system, and belongs to the technical field of on-board hydrogen storage systems. Background Technology
[0002] Currently, most on-board hydrogen storage systems are placed behind the driver's cab, which not only results in low integration but also affects the vehicle's cargo space, increases transportation costs, raises the vehicle's center of gravity, and reduces vehicle driving stability. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a layout structure for an on-board hydrogen storage system. This layout structure adopts a layout in which the gas cylinder is placed under the chassis, which can effectively utilize the vehicle space, increase the cargo box loading capacity, lower the vehicle center of gravity, and greatly increase the vehicle space utilization rate.
[0004] To solve the above problems, the specific technical solution of this utility model is as follows: a layout structure for an on-board hydrogen storage system, wherein system fixing brackets are set on two existing parallel frames of the vehicle body, and an external frame is connected to the two frames through the system fixing brackets; several main load-bearing brackets for hydrogen storage cylinders are fixedly connected to the external frame, and straps are set on the main load-bearing brackets for hydrogen storage cylinders, and several side-mounted gas cylinders are positioned on the external frame through the straps.
[0005] The external frame has a symmetrical two-tiered layout and a fence structure that surrounds the structure on three sides.
[0006] The vehicle has three fixed supports. One of the fixed supports at the end is directly connected to the fence of the outer frame, and the other two fixed supports are connected to the middle of the fence of the outer frame through the main load-bearing support of the hydrogen storage tank.
[0007] The outer frame has five bottom hydrogen storage cylinders at the bottom, with the middle bottom hydrogen storage cylinder located between the two frames; the top has two side-mounted hydrogen storage cylinders, and the side-mounted hydrogen storage cylinders and bottom hydrogen storage cylinders are connected to the outside of the frame by the main load-bearing brackets and straps.
[0008] The two bottom hydrogen storage cylinders on one side and the side-mounted hydrogen storage cylinder form a triangular structure.
[0009] The on-board hydrogen storage system layout structure of this application adopts the above structure and has the following advantages: 1. By using the existing vehicle frame to build a fixed support and adopting a side-mounted and bottom-mounted hydrogen storage tank integration method, the vehicle's center of gravity is lowered, driving stability is improved, and multiple hydrogen storage tanks are arranged in a reasonable manner within a limited space, which greatly increases the hydrogen storage capacity per unit space and effectively increases the vehicle's range. 2. The lightweight frame not only reduces the weight of the entire system and improves freight economy, but also provides stable and reliable support for the hydrogen storage tank, disperses external forces, and ensures safety under vibration / bump conditions. At the same time, it has been verified by crash testing to ensure the reliability of the system in the event of a car accident. 3. Adopting a modular design, it is suitable for different types of freight vehicles, with good compatibility, high integration, improved overall vehicle aesthetics, and convenient installation and maintenance.
