[0050] The embodiments of the present application will be described below in conjunction with Figures 1 to 8 The arrangement structure of the vehicle-mounted hydrogen energy system and the hydrogen energy vehicle provided by the embodiments of the present application are introduced.

[0051] As Figure 1 and Figure 2 , Figures 5 to 8 indicates that the first aspect embodiment of the present application provides an arrangement structure of a vehicle-mounted hydrogen energy system. The arrangement structure of the vehicle-mounted hydrogen energy system includes a vehicle chassis 100. The upper portion of the vehicle chassis 100 is formed with a cab mounting area 110 and a cargo box mounting area 120.

[0052] The vehicle chassis 100 usually includes a plurality of longitudinal beams, for example, includes two longitudinal beams in Figure 1 and Figure 2 The cab 200 is located in the cab mounting area 110, and the cargo box 800 is located in the cargo box mounting area 120.

[0053] The arrangement structure of the vehicle-mounted hydrogen energy system further includes an energy storage system 400. The energy storage system 400 stores hydrogen to supply hydrogen fuel cells 600 to generate electricity. As Figure 2 indicates, the energy storage system 400 usually includes an energy storage system mounting frame 410 and a hydrogen storage tank 420. The hydrogen storage tank 420 is placed in the energy storage system mounting frame 410, and the hydrogen storage tank 420 is used to store hydrogen.

[0054] The arrangement structure of the vehicle-mounted hydrogen energy system further includes a power battery system 500 for storing and releasing electric quantity. The electric quantity generated by the hydrogen fuel cell 600 can be stored into the power battery system 500, and the power battery system 500 supplies power to the hydrogen energy vehicle. Of course, the hydrogen fuel cell 600 can also directly supply power to the hydrogen energy vehicle in the case of acceleration or climbing, etc. The specific power supply mode can be various, which is not enumerated in detail here.

[0055] The hydrogen energy vehicle is usually a heavy truck, for example, a truck with a carrying capacity of more than 30 tons. Moreover, the hydrogen energy vehicle is usually used for long-distance transportation, which requires strong endurance. Therefore, the hydrogen storage tank 420 in the energy storage system 400 is usually large in volume, which can store enough hydrogen to provide power for a long distance. The volume of the power battery system 500 will be much smaller than that of the energy storage system 400, but in the case that the hydrogen in the energy storage system 400 is used up, the electric quantity stored by the power battery system 500 is needed to provide power for the hydrogen energy vehicle, so the power battery system 500 also has a certain volume.

[0056] Therefore, according to the embodiment of the present application, the energy storage system 400 is arranged on the vehicle chassis 100 and located below the cargo box mounting area 120. The power battery system 500 is arranged between the cab mounting area 110 and the cargo box mounting area 120.

[0057] The embodiment arranges the energy storage system 400 on the vehicle chassis 100 and below the cargo box 800, and arranges the power battery system 500 between the cab 200 and the cargo box 800. Since the volume of the power battery system 500 is usually much smaller than that of the energy storage system 400, the space occupied by the vehicle-mounted hydrogen energy system between the cab 200 and the cargo box 800 can be greatly reduced, thereby facilitating the extension of the length of the cargo box 800 and improving the carrying capacity of the hydrogen energy vehicle.

[0058] Moreover, the space between the cab 200 and the cargo box 800 also provides mounting space for accommodating the power battery system 500 with a certain volume, which facilitates the power battery system 500 to reserve a certain volume and have a large storage capacity, thereby improving the endurance of the hydrogen energy vehicle.

[0059] For the specific arrangement position of the energy storage system 400, further, in some embodiments, as shown in Figure 1 and Figure 2 The energy storage system 400 is distributed on both sides of the width direction of the vehicle chassis 100. The vehicle chassis 100 bears the energy storage system 400 on both sides, which not only increases the storage space of the energy storage system 400, but also facilitates the loading of more hydrogen energy, thereby improving the endurance of the hydrogen energy vehicle.

[0060] For the specific setting position of the power battery system 500, further, in some embodiments, as shown in Figure 1 、 Figure 2 and Figure 3 , the arrangement structure of the vehicle-mounted hydrogen energy system further comprises a cab 200 arranged in the cab mounting area 110, and the power battery system 500 is arranged at the back of the cab 200.

[0061] In these embodiments, the power battery system 500 can be directly mounted at the back of the cab 200, shortening the distance between the power battery system 500 and the cab 200, thereby facilitating the extension of the length of the cargo box 800. The power battery system 500 can also be mounted on the vehicle chassis 100, with the vehicle chassis 100 bearing the weight of the power battery system 500, or the power battery system 500 being fixedly connected to both the cab 200 and the vehicle chassis 100, with good installation stability.

[0062] As an example, the power battery system 500 can be connected to the cab 200 at multiple points in the height direction, which can improve the installation stability of the power battery system 500.

[0063] As an example, as shown in Figure 5 、 Figure 6 and Figure 7 , the power battery system 500 comprises a battery mounting rack 510 and a power battery 520, the power battery 520 is mounted in the battery mounting rack 510, and the battery mounting rack 510 is arranged at the back of the cab 200. Among them, the battery mounting rack 510 can be a multi-layer structure, and multiple power batteries 520 can be installed, which can store more electric energy and improve the endurance of the hydrogen energy vehicle.

[0064] In some embodiments, the back of the cab 200 has a power battery storage area recessed towards the interior of the cab 200, and part of the power battery system 500 is arranged in the power battery storage area.

[0065] In these embodiments, the power battery system 500 is moved forward to extend into the power battery storage area, occupying part of the space of the original cab mounting area 110, which facilitates the extension of the length of the cargo box 800 and improves the cargo carrying capacity.

[0066] As an example, the power battery storage area is located at the lower part of the back of the cab 200, which can correspond to the lower part of the seat of the cab 200, so that the recessed power battery storage area does not excessively affect the internal activity space of the cab 200. Moreover, it is also convenient for the power battery system 500 to be fixed on the vehicle chassis 100, improving the installation stability of the power battery system 500.

[0067] Further, in some embodiments, as shown in Figure 3 、 Figure 4 andFigure 5 As shown, the energy storage system 400 is a hydrogen storage system, and the arrangement structure of the vehicle hydrogen energy system further comprises: a hydrogen fuel cell 600, the cab 200 has a driving side and a non-driving side which are oppositely distributed, a hydrogen fuel cell storage area 310 recessed towards the inside of the cab 200 is arranged on the outer side of the non-driving side, and the hydrogen fuel cell 600 is arranged in the hydrogen fuel cell storage area 310.

[0068] In these embodiments, the outer side of the non-driving side of the cab 200 is provided with the hydrogen fuel cell storage area 310, and the hydrogen fuel cell 600 is arranged in the hydrogen fuel cell storage area 310, thereby occupying the space of the non-driving side of the cab 200. On the one hand, the hydrogen fuel cell 600 does not interfere with the activity space of the driver and does not affect driving. On the other hand, the hydrogen fuel cell 600 can be moved forward relative to the position of the engine under the cab 200 in the prior art, thereby facilitating the provision of space for the power battery storage area and the forward movement of the power battery system 500, and further facilitating the extension of the cargo box 800 to increase the load capacity.

[0069] It should be noted that the hydrogen fuel cell 600 in the prior art is located in the middle of the bottom of the cab 200, and if it is moved forward, it will interfere with the components in the gear shifting area and the partition between the driver's seat and the co-driver's seat. In the case of not greatly changing the internal structure of the cab 200, the hydrogen fuel cell 600 in the prior art cannot be moved forward. Therefore, in the present embodiment, the hydrogen fuel cell 600 is arranged in the hydrogen fuel cell storage area 310 on the outer side of the non-driving side of the cab 200, which can be moved forward without interference with the components in the gear shifting area and the partition between the driver's seat and the co-driver's seat, thereby facilitating the forward movement of the power battery system 500 and the extension of the length of the cargo box 800.

[0070] As an example, the co-driver's seat in the cab 200 can be removed, and the hydrogen fuel cell 600 can be arranged in the position under the original co-driver's seat and moved forward, which does not greatly change the internal functional components of the cab 200 and is convenient to process. Moreover, the co-driver is usually unoccupied during the transportation of a long-distance truck, and therefore, removing the co-driver's seat to increase the load capacity is a good way to improve transportation efficiency.

[0071] In some embodiments, as shown in Figs. 1-3, the hydrogen fuel cell storage area 310 is arranged on the outer side of the non-driving side of the cab 200. Figure 3 , Figure 5 and Figure 6 As shown, the hydrogen fuel cell storage area 310 is arranged on the lower part of the non-driving side. A bunk 210 is arranged on the non-driving side in the cab 200, and the hydrogen fuel cell storage area 310 is arranged below the bunk 210.

[0072] In these embodiments, the hydrogen fuel cell storage area 310 is located at the lower portion of the non-driving side, and the upper portion of the non-driving side is left with space, which is convenient for the driver to observe the rearview mirror and other components on the non-driving side, and also convenient for the non-driving side to have a window glass to facilitate ventilation and the like. In addition, a bunk 210 is arranged on the non-driving side inside the cab 200, and the hydrogen fuel cell storage area 310 is located below the bunk 210, which is convenient for the driver to rest on the bunk 210 on the non-driving side, although the co-driver seat is eliminated.

[0073] In these embodiments, the hydrogen fuel cell storage area 310 is located at the lower portion of the non-driving side, and the upper portion of the non-driving side is left with space, which is convenient for the driver to observe the rearview mirror and other components on the non-driving side, and also convenient for the non-driving side to have a window glass to facilitate ventilation and the like. In addition, a bunk 210 is arranged on the non-driving side inside the cab 200, and the hydrogen fuel cell storage area 310 is located below the bunk 210, which is convenient for the driver to rest on the bunk 210 on the non-driving side, although the co-driver seat is eliminated.

[0074] Further, in some embodiments, as shown in Figure 3 and Figure 4 , the arrangement of the vehicle-mounted hydrogen energy system further comprises a cab frame 300 arranged on the vehicle chassis 100, the cab frame 300 enclosing the internal space of the cab 200 and the hydrogen fuel cell storage area 310, the hydrogen fuel cell 600 being fixed on the battery bracket 620 through the battery suspension 610, and the battery bracket 620 being fixed on the cab frame 300 through bolts.

[0075] In these embodiments, the cab frame 300 has the internal space of the cab 200 and the hydrogen fuel cell storage area 310 inside, and the hydrogen fuel cell 600 occupies the original internal space of the cab frame 300, which is compact in structure. Moreover, the hydrogen fuel cell 600 is fixed on the battery bracket 620 through the battery suspension 610, and the battery bracket 620 is fixed on the cab frame 300 through bolts, so that the hydrogen fuel cell 600 is stably installed.

[0076] Further, in some embodiments, as shown in Figure 4 , the hydrogen fuel cell storage area 310 has an opening on the outside, and the hydrogen fuel cell maintenance door 320 is arranged at the opening. It is convenient to open the hydrogen fuel cell maintenance door 320 to maintain or replace the hydrogen fuel cell 600.

[0077] Further, in some embodiments, as shown in Figure 1 , Figure 2 and Figure 8As shown, the power battery maintenance door 330 is arranged at the back of the cab 200 and at least one side of the cab 200 in the width direction, and is used to shield the power battery system 500. Here, the power battery maintenance door 330 can play a shielding role on the one hand to improve the appearance effect, and on the other hand to facilitate opening of the power battery maintenance door 330 for maintenance or replacement of the power battery system 500.

[0078] Further, in some embodiments, as shown in Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown, the arrangement structure of the vehicle-mounted hydrogen energy system further comprises a hydrogen fuel cell heat dissipation system 700 arranged between the cab mounting area 110 and the container mounting area 120, and the hydrogen fuel cell heat dissipation system 700 is arranged above the power battery system 500 or on one side of the power battery system 500 in the width direction of the vehicle chassis 100.

[0079] In these embodiments, arranging the hydrogen fuel cell heat dissipation system 700 between the cab mounting area 110 and the container mounting area 120 and close to the hydrogen fuel cell 600 can shorten the pipeline connection structure and reduce costs. Moreover, arranging the hydrogen fuel cell heat dissipation system 700 above the power battery system 500 or on one side of the power battery system 500 in the width direction of the vehicle chassis 100 facilitates heat dissipation without increasing the distance between the cab 200 and the container 800, thereby facilitating the guarantee of the length of the container 800 and the guarantee of the load capacity.

[0080] As an example, the power battery maintenance door 330 can shield the hydrogen fuel cell heat dissipation system 700 and the power battery system 500 at the same time.

[0081] Further, in some embodiments, as shown in Figure 8 As shown, the arrangement structure of the vehicle-mounted hydrogen energy system further comprises a baffle 430 shielding the energy storage system 400. The baffle 430 can be arranged on the energy storage system mounting frame 410 to shield the hydrogen storage tank 420. The baffle 430 can also be arranged on both sides of the bottom of the container 800 and outside the energy storage system 400.

[0082] The second aspect of the utility model provides a hydrogen energy vehicle comprising the arrangement structure of the vehicle-mounted hydrogen energy system of any one of the above embodiments.

[0083] The hydrogen energy vehicle provided by the embodiments of the present aspect has the arrangement structure of the vehicle-mounted hydrogen energy system of any one of the above embodiments, and thus has the beneficial effects of any one of the above embodiments, which will not be described herein.

[0084] In some embodiments, the hydrogen energy vehicle includes, but is not limited to, a heavy truck.

[0085] The embodiment of the utility model provides a kind of new hydrogen energy dump truck whole car design thought and principle, and the whole car design is determined in the way of advancing from back to front, to solve the problem of reducing the load capacity. First, ensure the load space of the last side container 800, cannot be reduced, try to increase, utilize the space between cab 200 and container 800, make this part of space more become a part of container 800. The energy storage system 400 originally arranged here is moved to the lower side of container 800 by system calculation and analysis, adjusting capacity, combined with the actual situation of whole car, and is hung on the both sides of vehicle chassis 100.
