Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] like Figure 1 As shown, the hydrogen storage bottle provided in the embodiment of the utility model has a first filling port 101 at one end and a second filling port 102 at the other end; the inner cavity of the hydrogen storage bottle 100 is located between the first filling port 101 and the second filling port 102.
[0030] When the hydrogen storage bottle 100 is filled with hydrogen, the first filling port 101 and the second filling port 102 simultaneously fill hydrogen into the inner cavity of the hydrogen storage bottle 100. The gas pressure in the inner cavity of the hydrogen storage bottle 100 is gradually pressurized from the first filling port 101 and the second filling port 102 toward the middle of the inner cavity, and the temperature rises due to the pressurization. Not only is the hydrogenation efficiency higher, but the gas pressure and temperature distribution in the inner cavity of the hydrogen storage bottle 100 can also be made more uniform.
[0031] In the embodiment of the utility model, the hydrogen storage bottle 100 extends along the first dimension direction, and the hydrogen storage bottle 100 is symmetrical with respect to a plane perpendicular to the first dimension direction; along the first dimension direction, the first filling port 101 is arranged at one end of the hydrogen storage bottle 100, and the second filling port 102 is arranged at the other end of the hydrogen storage bottle 100. In other words, for the hydrogen storage bottle 100 having the first filling port 101 at one end and the second filling port 102 at the other end, the first dimension direction of the hydrogen storage bottle 100 is from the first filling port 101 to the second filling port 102. If the hydrogen storage bottle 100 is configured as an axisymmetric structure, the axial direction of the hydrogen storage bottle 100 can be defined as the first dimension direction.
[0032] Furthermore, the first filling port 101 and the second filling port 102 are coaxial and have the same size. The first filling port 101 and the second filling port 102 are symmetrical with respect to a plane perpendicular to the first dimension direction. The fluids injected from the first filling port 101 and the second filling port 102 are respectively distributed symmetrically in the inner cavity of the hydrogen storage bottle 100 with respect to a plane perpendicular to the first dimension direction, thereby improving the uniformity of temperature distribution of the hydrogen storage bottle 100 during hydrogenation.
[0033] Furthermore, one of the first filling port 101 and the second filling port 102 is equipped with a one-way valve leading to the hydrogen storage bottle 100. Among them, one of the first filling port 101 and the second filling port 102 is used as a hydrogen filling port, and the other is used as a gas replenishment port. A one-way valve is installed at the gas replenishment port to prevent the gas from flowing back out of the gas replenishment port due to the pressure difference at both ends of the hydrogen storage bottle 100. Gas can be replenished into the hydrogen storage bottle 100 through the first filling port 101 and the second filling port 102 without pressure stabilization.
[0034] The vehicle provided by the embodiment of the utility model is equipped with the hydrogen storage bottle 100 described in the above embodiment, and the hydrogen storage bottle 100 can provide hydrogen for the vehicle-mounted fuel cell. The first filling port 101 and the second filling port 102 are respectively equipped with bottle valves, and at least one of the first filling port 101 and the second filling port 102 is connected to the hydrogen supply pipeline of the fuel cell, and a pressure reducing valve, a discharge valve, etc. can also be installed in the hydrogen supply pipeline. The vehicle has the technical effect of the above hydrogen storage bottle 100, and has the technical advantages of high hydrogenation efficiency and more uniform temperature and pressure distribution of the hydrogen storage bottle 100 during hydrogenation.
[0035] like Figure 1 As shown, the hydrogen storage bottle filling equipment provided by the embodiment of the utility model includes: a hydrogen source 200, a first filling connector 300 and a second filling connector 400; the first filling connector 300 and the second filling connector 400 are respectively connected to the fluid of the hydrogen source 200, and the first filling connector 300 and the second filling connector 400 are adapted to the hydrogen storage bottle 100 described in the above embodiment; wherein, the first filling connector 300 is adapted to the first filling port 101, and the second filling connector 400 is adapted to the second filling port 102.
[0036] During hydrogen refueling, the first filling connector 300 is connected to the first filling port 101, and the second filling connector 400 is connected to the second filling port 102, and both ends of the hydrogen storage bottle 100 are filled with hydrogen at the same time, thereby building a fast hydrogen refueling station, improving the hydrogen refueling efficiency, and being conducive to improving the convenience and speed of hydrogen refueling of hydrogen energy vehicles, thereby improving the user experience.
[0037] Furthermore, the first filling connector 300 and the second filling connector 400 respectively include: a break valve 301, a hose 302 and a manual valve 303; the break valve 301 is in fluid communication with the hydrogen source 200, one end of the hose 302 is in fluid communication with the break valve 301, and the other end of the hose 302 is in fluid communication with the manual valve 303. The hose 302 is bendable so that the first filling connector 300 and the second filling connector 400 can move according to the position of the hydrogen storage bottle 100, and the manual valve 303 is used to control the on and off of the first filling connector 300 and the second filling connector 400 during hydrogenation, and the manual valves 303 of the first filling connector 300 and the second filling connector 400 can also be linked to achieve synchronous opening and closing.
[0038] The first filling connector 300 and the second filling connector 400 are respectively connected to the hydrogen source 200 through pipelines, and the pipelines are installed with a pressure control valve 500. The pressure control valve 500 can be used to adjust the filling pressure of the first filling connector 300 and the second filling connector 400, thereby ensuring balanced hydrogenation pressure.
[0039] Furthermore, the pipeline is also installed with a main control valve 600, and the on-off state of the hydrogen supply of the first filling connector 300 and the second filling connector 400 can be controlled by adjusting the opening and closing of the main control valve 600.
[0040] The hydrogen storage and filling system provided by the embodiment of the utility model includes: a hydrogen storage bottle 100, a hydrogen source 200, a first filling connector 300 and a second filling connector 400; a first filling port 101 is provided at one end of the hydrogen storage bottle 100, and a second filling port 102 is provided at the other end, and the inner cavity of the hydrogen storage bottle 100 is located between the first filling port 101 and the second filling port 102; the first filling connector 300 and the second filling connector 400 are respectively connected to the fluid of the hydrogen source 200, the first filling connector 300 is detachably connected to the first filling port 101, and the second filling connector 400 is detachably connected to the second filling port 102. The hydrogen storage and filling system has an extended implementation method corresponding to the above-mentioned hydrogen storage bottle 100 and filling equipment, and has the same technical effects as them, which will not be repeated here.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
