When the hydrogen supply assembly 110 needs to be overhauled, the lower shield 123 is flipped over relative to the hinge between the side shield 122 and the lower shield 123 to partially expose the hydrogen supply assembly 110, thereby improving the maintenance convenience of the hydrogen supply assembly 110.

[0029] For example, the lower shield 123 can be hingedly installed on one side shield 122 to facilitate the maintenance of the hydrogen supply assembly 110 by flipping over the lower shield 123 on the side where the lower shield 123 is installed.

[0030] For another example, the lower shield 123 can be hingedly installed on both side shields 122 to further improve the maintenance convenience of the hydrogen supply assembly 110.

[0031] The hydrogen supply system 100 provided by the present application includes a hydrogen supply assembly 110 and a shield 120. The shield 120 includes a top shield 121 covering the top end of the hydrogen supply assembly 110 and side shields 122 covering both sides of the hydrogen supply assembly 110. At least one side shield 122 is hingedly connected to a lower shield 123. The lower shield 123 is flipped over relative to the hinge between the side shield 122 and the lower shield 123 to partially expose the hydrogen supply assembly 110, thereby improving the maintenance convenience of the hydrogen supply system 100.

[0032] In one possible embodiment of the present application, as shown in Figure 1 , Figure 2 and Figure 3 , the side wall of the hydrogen supply assembly 110 is provided with a hydrogen filling hole. When the lower shield 123 is included, the lower shield 123 is arranged on the same side as the hydrogen filling hole.

[0033] Specifically, the hydrogen filling hole on the hydrogen supply assembly 110 has maintenance needs.

[0034] In one possible embodiment of the present application, as shown in Figure 1 , Figure 2 and Figure 3 , the lower shield 123 is provided with a hydrogen filling port 1231 corresponding to the hydrogen filling hole.

[0035] In use of the hydrogen supply system 100 of the present application, when the hydrogen tank of the hydrogen supply assembly 110 needs to be filled with hydrogen, the hydrogen filling port 1231 is communicated with the hydrogen filling hole on the hydrogen supply assembly 110 through the hydrogen filling port 1231 to fill the hydrogen supply assembly 110 with hydrogen.

[0036] When the lower shield 123 comprises one, the lower shield 123 is arranged at the hydrogen filling hole of the hydrogen supply assembly 110, so as to facilitate the maintenance of the hydrogen filling side of the hydrogen supply assembly 110.

[0037] When the lower shield 123 comprises two, one of the lower shields 123 is arranged with a hydrogen filling port 1231 corresponding to the position of the hydrogen filling hole, and the other lower shield 123 does not need to be arranged with the hydrogen filling port 1231.

[0038] In an embodiment of the present application, as shown in Figure 1 , Figure 2 and Figure 3 , the lower shield 123 is further arranged with a hydrogen filling cover 1232, and the hydrogen filling port 1231 is covered by the hydrogen filling cover 1232.

[0039] In use of the hydrogen supply system 100 of the present application, when the hydrogen tank of the hydrogen supply assembly 110 needs to be filled with hydrogen, the hydrogen filling cover 1232 on the lower shield 123 is opened, the hydrogen supply pipeline passes through the hydrogen filling port 1231 and communicates with the hydrogen filling hole on the hydrogen supply assembly 110, so as to fill the hydrogen supply assembly 110 with hydrogen, and after the hydrogen filling is completed, the hydrogen filling cover 1232 is covered on the hydrogen filling port 1231.

[0040] In an embodiment of the present application, as shown in Figure 1 , Figure 2 and Figure 3 , the gas supporting rod 1233 is arranged between the lower shield 123 and the hydrogen supply assembly 110, one end of the gas supporting rod 1233 is rotatably connected with the side shield 122, and the other end is rotatably connected with the hydrogen supply assembly 110.

[0041] Specifically, the gas supporting rod 1233 is filled with high-pressure nitrogen gas. When the piston rod moves under the action of external force, the gas will be compressed or expanded, generating a corresponding supporting force. By adjusting the pressure of the gas, the supporting force and damping effect of the gas supporting rod 1233 can be controlled.

[0042] In use of the hydrogen supply system 100 of the present application, when the hydrogen supply assembly 110 needs to be maintained, the lower shield 123 can be supported by the gas supporting rod 1233 when the lower shield 123 is flipped open relative to the side shield 122, so as to facilitate the maintenance operation of the exposed part of the hydrogen supply assembly 110 by the operator.

[0043] It can be understood that a metal supporting rod can also be arranged on the lower shield, one end of the metal supporting rod is rotatably connected with the lower shield, a clamping groove is arranged on the hydrogen supply assembly 110 and clamps the other end of the metal supporting rod, when the lower shield is flipped to expose the hydrogen supply assembly 110, the other end of the metal supporting rod is clamped with the clamping groove, so that the flipped lower shield maintains a predetermined flip angle, so as to facilitate the maintenance of the exposed part of the hydrogen supply assembly 110.

[0045] In use of the hydrogen supply system 100 of the present application, when the hydrogen supply assembly 110 needs to be maintained, the lock catch 1234 on the lower cover 123 is opened to release the locking of the lower cover 123 and the hydrogen supply assembly 110, and when the lower cover 123 is flipped open relative to the side cover 122, the lower cover 123 can be supported by the air supporting rod 1233, so as to facilitate the maintenance operation of the exposed part of the hydrogen supply assembly 110 by the operator.

[0046] In an embodiment of the present application, as shown in Figure 1 , Figure 2 and Figure 3 , the top cover 121 is provided with a plurality of first connecting holes 1211, and the hydrogen supply assembly 110 and the top cover 121 are connected through fasteners passing through the first connecting holes 1211, and the side cover 122 is provided with a plurality of second connecting holes 1221, and the hydrogen supply assembly 110 and the side cover 122 are connected through fasteners passing through the second connecting holes 1221.

[0047] Specifically, in assembly of the hydrogen supply system 100 of the present application, the top cover 121 is installed on the top of the hydrogen supply assembly 110, and the hydrogen supply assembly 110 and the top cover 121 are connected through fasteners passing through the first connecting holes 1211, the side cover 122 is installed on both sides of the hydrogen supply assembly 110, and the hydrogen supply assembly 110 and the side cover 122 are connected through fasteners passing through the second connecting holes 1221, and the lower cover 123 is hingedly installed on the side cover 122, and when the hydrogen supply assembly 110 needs to be repaired, the lower cover 123 is flipped relative to the hinge between the side cover 122 and the lower cover 123 to partially expose the hydrogen supply assembly 110, so as to improve the maintenance convenience of the hydrogen supply assembly 110.

[0048] In an embodiment of the present application, as shown in Figure 1 , Figure 2 and Figure 3 , the top cover 121 and the side cover 122 are made of glass steel material.

[0049] Since the density of the glass fiber reinforced plastic adopted by the top cover 121 and the side cover 122 is far less than that of the steel material, the load bearing performance requirement for the hydrogen supply assembly 110 arranged inside is lower, and the hydrogen supply assembly 110 does not need too many internal support structures for preventing deformation, the structure is simpler, the weight is greatly reduced, and compared with the steel structure of the same size requirement, the weight can be reduced by more than 70%, so that the product hoisting and assembly are more convenient and fast.

[0050] Further, a plurality of hollowed-out areas can be arranged on the side cover 122 to further reduce the overall weight of the cover 120.

[0051] In an embodiment of the present application, as shown in Figure 1 、 Figure 2 and Figure 3 Figure 1 Figure 2 Figure 3 , the front end of the top cover 121 has an arc-shaped guide section, and the arc-shaped guide section is bent towards the hydrogen supply assembly 110.

[0052] Specifically, the front end of the top cover 121 is arranged as an arc-shaped guide section, and the arc-shaped guide section is bent towards the hydrogen supply assembly 110, so as to reduce the wind resistance during driving of the hydrogen fuel vehicle.
