[0002] A hydrogen fuel cell refers to a device that generates electricity through a chemical reaction between hydrogen and oxygen. The driving force of a hydrogen fuel cell vehicle comes from the electric motor on the vehicle, just like a pure electric vehicle. Therefore, a hydrogen fuel cell vehicle can be understood as an electric vehicle with its own hydrogen fuel generator.

[0003] For example, a patent document with announcement number CN 220249643 U discloses a hydrogen storage device for a hydrogen-powered vehicle, comprising a main body, a plurality of slots being provided on the outer wall at the rear end of the main body, a through slot being provided at the center of the outer wall at the front end of the slot, a gas tank being snap-fitted on the inner wall of the through slot, two gas output ports being fixedly connected to the outer wall at the front end of the gas tank, a support block being fixedly connected to the middle of the inner wall of the gas output port, a threaded block being fixedly connected to the front end of the inner wall of the gas output port, a nut being threadedly connected to the outer wall of the threaded block, and in the utility model, compared with the existing hydrogen storage device for a hydrogen-powered vehicle, a sealing plug is provided on the exhaust port of the gas tank in the hydrogen storage device for a hydrogen-powered vehicle, and the sealing plug can be tightly fitted on the threaded block through a spring and the pressure inside the gas tank, so that the gas tank has the function of only inlet but not outlet, thereby improving the sealing performance of the gas tank and increasing the safety of the gas tank.

[0004] However, in actual use, this structure can only be installed in a fixed manner, resulting in the inability of the overall hydrogen storage device to obtain efficient buffering and protection operations when moving with the vehicle. At the same time, the equipment is unable to perform more limited and adaptive disassembly, maintenance and use operations of the hydrogen storage device for hydrogen energy vehicles, and cannot meet daily use needs. Therefore, it is urgent to design a hydrogen storage device for hydrogen energy vehicles to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a hydrogen storage device for a hydrogen energy vehicle, so as to solve the problem that the existing structure proposed in the above background technology can only be installed in a fixed manner during actual use, resulting in the inability of the overall hydrogen storage device to obtain efficient buffering and protection operation when moving with the vehicle, and the equipment is unable to perform more limited and adaptive disassembly, maintenance and use operations of the hydrogen storage device for hydrogen energy vehicles, and cannot meet daily use needs.

[0006] To achieve the above object, the utility model provides the following technical solution: a hydrogen storage device for a hydrogen energy vehicle, comprising a mounting frame, a storage tank is movably connected inside the mounting frame, a first set of cover is provided at one end of the mounting frame, and a second set of cover is provided at the other end of the mounting frame;

[0007] The mounting seat is fixedly connected to the bottom end of the mounting frame, a supporting base is arranged at the bottom of the mounting seat, a fixing seat is fixedly connected to the surface of the supporting base, and a plug-in socket is fixedly connected to the surface of the fixing seat.

[0010] Preferably, buffer springs are evenly arranged on the four sides of the plug-in frame, and damping rubber seats are arranged on the four corners of the side of the plug-in frame.

[0011] Preferably, a plug-in rack is provided on the inner wall of the mounting frame, and a plug-in strip is provided on the bottom of the storage tank.

[0012] Preferably, a limiting rubber cover is provided inside the first set of covers and the second set of covers, and a limiting ring is provided at the back center of the limiting rubber cover.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The hydrogen storage device for hydrogen energy vehicle, through the arranged mounting frame, storage tank, mounting seat, support base, fixed seat, plug-in seat, limit rolling ball, fixed screw hole, plug-in frame, fixing bolt, buffer spring and damping rubber seat, can make the storage tank as a whole obtain stable buffer protection operation at all times when it is used with the movement of hydrogen energy vehicle. In the actual use process, the staff firstly carry out adaptive docking operation of the mounting frame and the storage tank as a whole with the support base through the mounting seat at the bottom. After docking, the plug-in seat on the surface of the fixed seat can be stably clamped in the inside of the plug-in frame, and then tighten the plug-in frame surface. The fixing bolts on the four sides of the surface are locked and fixed at the fixing screw holes on the surface of the fixing seat to realize the fixed installation operation between the mounting seat and the supporting base. At this time, when the mounting frame and the storage tank vibrate with the movement of the hydrogen energy vehicle, the buffer spring and the damping rubber seat on the side of the plug-in frame can perform stable damping and buffering protection operations to ensure the safety of use inside the storage tank at all times. At the same time, when the mounting seat and the supporting base move relative to each other, the limit rolling balls on the four sides of the surface of the supporting base can perform stable limit rolling operations to avoid wear problems between the two, which reflects the practicality of the equipment design.

[0015] The hydrogen storage device for hydrogen energy vehicle further improves the overall use effect of the equipment through the installation frame, storage tank, first set of equipment covers, second set of equipment covers, plug-in frame, plug-in strip, limit rubber cover and limit collar. In daily use, the staff can quickly dock and install the storage tank to be used as a whole to the plug-in frame on the inner wall of the installation frame through the plug-in strip structure at the bottom, thereby ensuring rapid docking and installation between the installation frame and the storage tank, and facilitating the subsequent removal and replacement of the storage tank as a whole. At the same time, the hydrogen flow pipelines at both ends of the storage tank can be installed at the first set of equipment covers and the second set of equipment covers at both ends of the storage tank. The first set of equipment covers and the second set of equipment covers are used to stably limit the two ends of the storage tank on a daily basis. The internal limit rubber covers and limit collars are also used to perform stable damping buffering and limiting operations on the pipelines, so that they can be synchronously adjusted with the buffering of the entire installation frame, reflecting the comprehensiveness of the equipment design.
