[0002] The on-board hydrogen storage system is an important component of fuel cell vehicles, including high-pressure hydrogen storage bottles, integrated bottle valves, filling ports, one-way valves, filters, pressure reducing valves, high-pressure and low-pressure sensors, hydrogen pipelines and other components. Its main function is to provide hydrogen with stable pressure and flow for the fuel cell system.

[0003] After searching, the patent (application number: 202022657898.3) discloses "a hydrogen fuel cell bus hydrogen storage system installation structure". The device can independently manufacture installation brackets and welding brackets, which can effectively reduce welding deformation and improve the manufacturing accuracy of the bracket assembly. After assembly, the whole vehicle can be assembled and installed at one time to improve the assembly efficiency of the vehicle. However, the device has the following problems in actual use:

[0004] First of all, the device is integrally formed, which means that the installation position of each hydrogen storage tank is fixed. However, the device needs to be installed in a hydrogen fuel bus. The installation environment inside the vehicle is relatively complex. If the position of the hydrogen storage tank cannot be adjusted, subsequent pipeline connection, wiring and other steps will become complicated.

[0005] In addition, the hydrogen storage tank is installed in the device, and the top of the hydrogen storage tank is very open without any protective structure. The hydrogen storage tank is flammable and explosive. Once a strong collision occurs, it will seriously endanger the safety of life and property, and it is dangerous. Utility Model Content

[0009] Push rods are welded to the inner walls on both sides of the frame body, and symmetrically distributed anti-pressure frames are hinged to the outer wall at the top of the frame body, and springs are connected between the push rods and the anti-pressure frames.

[0010] Preferably, the frame includes symmetrically distributed vertical rods and horizontal rods, and the vertical rods and the horizontal rods are welded to each other.

[0011] Preferably, a reinforcement rod is welded to the outer wall of one side of the cross rod and the top rod.
