[0041] The following describes a hydrogenation installation structure 100 according to an embodiment of the first aspect of the utility model with reference to the accompanying drawings.

[0042] According to the hydrogen refueling installation structure 100 of the vehicle-mounted hydrogen system 1000 of the embodiment of the utility model, Figure 1 As shown, the hydrogenation installation structure 100 includes: a cantilever rod 1, a rod end fixing portion 2 and a hydrogenation module 3. Figure 2 As shown, at least one bending portion 1a is provided on the cantilever rod 1, the rod end fixing portion 2 is connected to one end of the cantilever rod 1 for fixing on the vehicle body longitudinal beam 3000, and the hydrogenation module 3 is connected to the other end of the cantilever rod 1, and the hydrogenation module 3 is higher than the rod end fixing portion 2.

[0043] The hydrogenation installation structure 100 of the first embodiment of the utility model is used for a vehicle-mounted hydrogen system 1000, and the hydrogenation installation structure 100 has a connection interface for hydrogen fuel filling, which plays a key role in the vehicle-mounted hydrogen system 1000. The hydrogenation installation structure 100 can ensure that the connection interface for hydrogen fuel filling can be firmly connected to the vehicle or equipment to ensure the safety and filling efficiency during the hydrogen fuel filling process.

[0044] The rod end fixing portion 2 is used to firmly connect the hydrogenation mounting structure 100 to the vehicle. The hydrogenation module 3 has a connection interface for hydrogen fuel filling. One end of the cantilever rod 1 is connected to the rod end fixing portion 2, and the other end of the cantilever rod 1 is connected to the hydrogenation module 3 to firmly connect the hydrogenation module 3 to the vehicle to ensure safety and efficiency during hydrogen fuel filling.

[0045] In the related art, the hydrogen refueling installation structure and the hydrogen storage system share a bracket, and additional design is required for the bracket of the hydrogen storage system to support the layout of the hydrogen refueling installation structure. This will increase the envelope size of the hydrogen storage system, increase the spatial volume of the on-board hydrogen system, increase the space occupied by the entire vehicle, and is not conducive to the layout of the on-board hydrogen system.

[0046] The hydrogen refueling installation structure 100 in the embodiment of the utility model is fixed on the vehicle body longitudinal beam 3000. Compared with arranging the hydrogen refueling installation structure on the hydrogen storage system, the utility model connects the hydrogen refueling installation structure 100 and the hydrogen storage structure to the vehicle respectively. The hydrogen refueling installation structure 100 and the hydrogen storage structure are arranged separately, which can reduce the envelope size of the hydrogen storage system, reduce the space occupancy rate of the on-board hydrogen system 1000, and facilitate the arrangement of the on-board hydrogen system 1000.

[0047] The two ends of the cantilever rod 1 are connected to the rod end connection part and the hydrogenation module 3. The cantilever rod 1 is provided with at least one bending part 1a. The cantilever rod 1 can not only firmly connect the hydrogenation module 3 to the vehicle body longitudinal beam 3000, but also arrange the hydrogenation module 3 according to the vehicle body structure. On the one hand, by selecting the bending angle of the bending part 1a, the length of the cantilever rod 1 and the height of the cantilever rod 1, the space occupied by the hydrogenation installation structure 100 can be reduced and the interference with other components can be improved; on the other hand, the structure of the cantilever rod 1 can also be selected according to the vehicle body structure, so that the hydrogenation installation structure 100 can be adapted to a variety of different types of vehicles, thereby improving the application scope of the hydrogenation installation structure 100. By setting the bending part 1a, the structural strength of the cantilever rod 1 can also be improved, and the layout stability of the hydrogenation installation structure 100 can be improved.

[0048] The hydrogenation installation structure 100 is fixed on the vehicle body longitudinal beam 3000. The height of the vehicle body longitudinal beam 3000 is relatively low. The hydrogenation module 3 is arranged higher than the rod end fixing part 2 through the cantilever rod 1, so that the position of the hydrogenation module 3 can be closer to the user's operating height, which is convenient for the filling of hydrogen fuel and improves the filling efficiency.

[0049] According to the hydrogenation installation structure 100 of the vehicle-mounted hydrogen system 1000 of the embodiment of the utility model, the hydrogenation installation structure 100 and the hydrogen storage structure are connected to the vehicle respectively, and the hydrogenation installation structure 100 and the hydrogen storage structure are arranged separately, so that the envelope size of the hydrogen storage system can be reduced, and the space occupancy rate of the vehicle-mounted hydrogen system 1000 can be reduced. In addition, the cantilever rod 1 can arrange the hydrogenation module 3 according to the vehicle body structure, which can further reduce the space occupied by the hydrogenation installation structure 100, improve the interference with other components, and simplify the layout difficulty.

[0050] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the cantilever rod 1 includes: a first rod segment 11, a second rod segment 12 and a third rod segment 13, one end of the first rod segment 11 is connected to the rod end fixing portion 2, the second rod segment 12 is vertically arranged, the lower end of the second rod segment 12 is connected to the other end of the first rod segment 11, the third rod segment 13 is horizontally arranged, the third rod segment 13 is connected to the upper end of the second rod segment 12, and the hydrogenation module 3 is installed on the third rod segment 13.

[0052] The first rod segment 11 is connected to the rod end fixing portion 2, the third rod segment 13 is connected to the hydrogenation module 3, and the second rod segment 12 is connected between the first rod segment 11 and the third rod segment 13. The second rod segment 12 extends vertically so that the hydrogenation module 3 on the third rod segment 13 is higher than the rod end fixing portion 2 connected to the first rod segment 11, which is convenient for the user's refueling operation.

[0053] The cantilever rod 1 has a first rod segment 11, a second rod segment 12 and a third rod segment 13. The arrangement position of the hydrogenation module 3 can be changed by controlling the length or extension direction of the first rod segment 11, the second rod segment 12 and the third rod segment 13, which can reduce the space occupied by the hydrogenation installation structure 100 and improve the interference with other components.

[0054] By setting the first rod segment 11, the second rod segment 12 and the third rod segment 13, the hydrogenation module 3 can be arranged in three directions relative to the vehicle body longitudinal beam 3000, and the arrangement flexibility of the hydrogenation installation structure 100 is higher, so that the hydrogenation module 3 can be arranged in multiple angles, multiple heights and multiple directions in space.

[0056] In addition, the first rod segment 11, the second rod segment 12, and the third rod segment 13 are vertically arranged in pairs. The first rod segment 11, the second rod segment 12, and the third rod segment 13 can arrange the hydrogenation module 3 in six directions in the horizontal and vertical directions relative to the vehicle body longitudinal beam 3000, thereby realizing the multi-angle, multi-height, and multi-directional arrangement of the hydrogenation module 3 in space.

[0057] In some embodiments of the present invention, the cantilever rod 1 is an integrally formed part, which can improve the structural reliability of the cantilever rod 1. After the cantilever rod 1 is manufactured and formed, the cantilever rod 1 is bent in two sections using a bending device to complete the structure of the first rod section 11, the second rod section 12 and the third rod section 13 of the cantilever rod 1.

[0059] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the hydrogenation installation structure 100 further includes: a first reinforcing plate 4 connected between the first rod segment 11 and the second rod segment 12 to improve the structural strength of the cantilever rod 1 and improve the layout stability of the hydrogenation installation structure 100 .

[0060] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the hydrogenation module 3 includes: a hydrogenation panel 31, a hydrogenation port structure 32 and a protective shell 33.

[0062] The protective shell 33 is used to protect the internal hydrogenation panel 31, the hydrogenation installation port 311 and the hydrogenation port structure 32, which can reduce the entry of external pollutants such as dust and water into the protective shell 33, reduce the pollution and damage to the hydrogenation port structure 32, thereby ensuring the cleanliness of the hydrogen fuel filling process, reducing the damage and failure of the system pipe valves and non-metallic seals due to impurities, slowing down the life reduction rate of the hydrogenation installation structure 100 and the on-board hydrogen system 1000, and extending the service life.

[0063] In some embodiments of the present invention, a protective layer is provided on the surface of the protective shell 33 to enhance the anti-rust effect of the protective shell 33 and extend the service life of the protective shell 33.

[0064] In some embodiments of the present invention, the protective shell 33 is fixedly connected to the hydrogenation panel 31 by an M6 bolt assembly.

[0066] The cantilever rod 1 is a round rod, and has a simple structure and low manufacturing cost. When the cantilever rod 1 is directly connected to the hydrogenation panel 31 using the circumference, the cantilever rod 1 and the hydrogenation panel 31 are tangent, the contact area between the cantilever rod 1 and the hydrogenation panel 31 is small, and the connection is unreliable.

[0067] The embodiment of the utility model utilizes the arc-shaped connecting plate 5 to connect the cantilever rod 1 and the hydrogenation panel 31.
