Description

Technical Field

[0001] This invention relates to the field of automotive hydrogen supply and storage equipment technology, and particularly to a hydrogen supply system and vehicle. Background Technology

[0002] With the development of hydrogen fuel cell vehicles, there are higher requirements for vehicle range. Taking the most mature and widely used high-pressure hydrogen storage system as an example, vehicles need to carry more hydrogen cylinders to bring a larger hydrogen storage capacity and thus improve the driving range.

[0003] In related technologies, due to the large size of high-pressure hydrogen storage systems and the limited space for vehicle chassis layout, most tractor-mounted hydrogen storage systems currently adopt a cab-back structure layout.

[0004] However, due to limitations in hydrogen storage capacity and the current state of hydrogen storage technology, high-pressure hydrogen storage systems are relatively large. Using a rear-mounted design would occupy a significant amount of space behind the cab, increasing the vehicle's wheelbase. The increased wheelbase resulting from the hydrogen storage system has become an unavoidable problem.

[0005] Therefore, it is necessary to design a new hydrogen supply system and vehicle to overcome the above problems. Summary of the Invention

[0006] This invention provides a hydrogen supply system and vehicle to solve the problem that in related technologies, the use of a rear-mounted hydrogen storage system would occupy a large amount of space behind the driver's cab, increasing the wheelbase of the vehicle.

[0007] In a first aspect, a hydrogen supply system is provided for placement behind the cab of a vehicle, wherein the vehicle includes a trailer. The hydrogen supply system includes: a housing having a hydrogen storage chamber therein, a hydrogen cylinder disposed within the hydrogen storage chamber, the housing having a front face facing the cab and a rear face opposite to the front face, at least a portion of the rear face being recessed toward the front face to form a groove; when the hydrogen supply system is placed behind the cab, at least a portion of the turning radius envelope of the trailer lies within the groove.

[0008] In some embodiments, the groove has a first inner wall surface and a second and a third inner wall surface connected to the first inner wall surface. The second and third inner wall surfaces are located on opposite sides of the first inner wall surface, and the first inner wall surface is parallel to the front end face. The second and third inner wall surfaces extend obliquely away from each other from their connection with the first inner wall surface. The second and third inner wall surfaces can be located on the left and right sides of the first inner wall surface, respectively, and extend obliquely to the left and right sides, forming an outwardly expanding groove. The opening of the groove gradually increases, so that the concave shape of the groove can be adapted to the shape of the turning radius envelope of the trailer, reducing the space occupied by the hydrogen supply system while maintaining a relatively large space inside the shell.

[0009] In some embodiments, the housing is further provided with guide surfaces on opposite sides of the front end face. The guide surfaces are connected to the front end face, and the two guide surfaces extend backward from their connection with the front end face in a direction that is further away from each other. In this embodiment, by providing guide surfaces on both sides, the airflow in front of the vehicle can be guided to the left and right sides of the vehicle respectively through the two guide surfaces, which can better adapt to the low wind resistance design of the tractor.

[0010] In some embodiments, the housing also includes a heat dissipation cavity, which is separated from the hydrogen storage cavity by a skin. A radiator is installed within the heat dissipation cavity. This design creates separate, independent areas within the housing for the radiator and the hydrogen cylinder, ensuring that the airflow from the radiator's fan does not affect the effectiveness of the concentration sensor inside the hydrogen storage cavity, and preventing hydrogen from entering the fan area and causing a hazard, thus better guaranteeing safety.

[0011] In some embodiments, the housing further has side surfaces located on opposite sides of the front end face, each side surface having an air inlet grille. A heat dissipation cavity is provided at each of the side surfaces, and the air inlet grille communicates with the corresponding heat dissipation cavity. The radiator is arranged at an angle relative to the corresponding side surface, creating an air intake space between the radiator's air intake surface and the corresponding air inlet grille. In this embodiment, the radiator is angled, ensuring that there is a certain air intake area in front of the radiator's air intake surface, and that the radiator's air intake surface faces the direction of the incoming wind, thus better ensuring the high efficiency of the radiator's fan.

[0012] In some embodiments, the housing has two inclined plates with the same tilt angle as the corresponding heat sink. The outer surfaces of the two inclined plates form the groove, and the inclined plates are provided with air outlets. The heat sink is fixed to the corresponding inclined plate, the air outlet surface of the heat sink is in contact with the inclined plate, and the air outlet surface of the heat sink is correspondingly arranged with the air outlet. In this embodiment, since the inclined plates have the same tilt angle as the corresponding heat sink, the air outlet surface of the heat sink can be in contact with the inclined plate, and the air outlet surface of the heat sink is correspondingly arranged with the air outlet. The air blown out by the heat sink can be directly blown out through the air outlet. Furthermore, due to the arrangement of the groove, a certain space area is maintained behind the air outlet surface of the heat sink, and the air blown out by the heat sink is not easily blocked, further increasing the efficiency of the heat sink.

[0013] In some embodiments, a guide vane is also provided on one side of the side surface. The guide vane is connected to the skin and is positioned between the heat dissipation cavity and the hydrogen storage cavity to separate them. The guide vane bends and extends from the air inlet grille toward the corresponding radiator. In this embodiment, two guide vanes can be provided, with one guide vane at each heat dissipation cavity. The guide vanes can guide the air entering from the air inlet grille toward the air intake surface of the radiator, ensuring that the entire air inlet grille can function as an intake, guaranteeing the air intake volume of the radiator, while reducing wind resistance and improving the heat dissipation efficiency of the radiator.

[0014] In some embodiments, the housing further includes a cavity disposed below the hydrogen storage chamber. In this embodiment, a space is left below the hydrogen storage chamber to accommodate other system components.

[0015] In some embodiments, the front end face is provided with a hydrogen vent, which is connected to the hydrogen storage cavity.

[0016] Secondly, a vehicle is provided, comprising a frame, a driver's cab mounted at the front end of the frame, and the aforementioned hydrogen supply system mounted on the frame, the hydrogen supply system being arranged behind the driver's cab. The hydrogen vent allows air to flow into or out of the hydrogen storage cavity, increasing airflow, and when hydrogen leaks from the hydrogen cylinder, the leaked hydrogen can flow out from the hydrogen vent.

[0017] The beneficial effects of the technical solution provided by this invention include:

[0018] This invention provides a hydrogen supply system and a vehicle. Because the rear of the hydrogen supply system housing is recessed forward to form the groove, when the hydrogen supply system is placed behind the cab, the turning radius envelope of the trailer is at least partially located within the groove. That is, after the groove is provided behind the housing, the trailer's installation position on the vehicle can be moved forward a certain distance, so that the turning radius envelope of the trailer is at least partially located within the groove. Moving the trailer forward effectively shortens the increase in the vehicle's wheelbase caused by the rear-mounted hydrogen supply system. Therefore, even if the hydrogen supply system is placed behind the cab, the overall vehicle wheelbase can be effectively reduced. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Wheelbase is of great significance for commercial vehicles. A smaller wheelbase ensures a smaller turning radius, resulting in better handling and improved passability. Therefore, the overall wheelbase is a key factor considered by the market and customers. However, the hydrogen storage system in related technologies occupies a large space behind the cab, leading to an increase in the overall wheelbase, which is detrimental to the vehicle's handling and passability.

[0036] Meanwhile, as the power of the fuel cell system increases, the heat dissipation requirements also increase. In related technologies, the power and size of the cooling fan also increase accordingly. The arrangement of the radiator has also become a challenge in the overall vehicle layout. Currently, the cooling fan is mostly mounted on the side of the vehicle frame, on the back of the hydrogen storage system, or on top of the hydrogen storage system.

[0037] Regarding the cooling fan, the side-mounted design has one side facing the inside of the vehicle frame, while the arrangement behind or on top of the hydrogen storage system results in one side of the radiator being close to the system's skin, both of which lead to poor airflow and low cooling efficiency. If the radiator is integrated into the side of the hydrogen storage system, the airflow will affect the accuracy of the hydrogen concentration sensor inside the system, and there are also some electrical components in the cooling fan, which pose a certain risk if hydrogen passes through the fan, creating a safety hazard.

[0038] This invention provides a hydrogen supply system and vehicle that solves the problem that using a rear-mounted hydrogen storage system in related technologies would occupy a large amount of space behind the driver's cab and increase the wheelbase of the vehicle.

[0039] See Figure 1 and Figure 7 As shown, an embodiment of the present invention provides a hydrogen supply system 100, which is arranged behind the cab 300 of a vehicle. The vehicle may include a frame 200 and a trailer 400 mounted on the frame 200. The cab 300 is mounted at the front end of the frame 200, and the trailer 400 is located behind the cab 300. The hydrogen supply system 100 can be installed above the frame 200 and between the cab 300 and the trailer 400. The hydrogen supply system 100 is characterized by including: a housing 1, which may have a hydrogen storage chamber 11 inside. The hydrogen storage chamber 11 contains a hydrogen cylinder 2, which stores hydrogen. The housing 1 has a front face 12 facing the cab 300, i.e., when the hydrogen supply system 100 is installed on the vehicle, the front face 12 faces the cab 300. 2. The front face 12 faces the cab 300. The housing 1 also has a rear face 13 opposite to the front face 12. That is, the front face 12 and the rear face 13 are located at the front and rear of the housing 1, respectively. At least a portion of the rear face 13 is recessed towards the front face 12 to form a groove 14. That is, the groove 14 is formed by the rear end of the housing 1 being recessed forward (or towards the interior of the housing 1). When the hydrogen supply system 100 is arranged behind the cab 300, the turning radius envelope 401 of the trailer 400 is at least partially located within the groove 14. That is, the trailer 400 mounted on the frame 200 can rotate on the frame 200. The turning radius envelope 401 formed by the entire tilting and rotating motion of the trailer 400 will at least partially enter the groove 14.

[0040] In this embodiment, because the rearward indentation of the hydrogen supply system 100 housing 1 forms the groove 14, when the hydrogen supply system 100 is placed behind the cab 300, the turning radius envelope 401 of the trailer 400 can be at least partially located within the groove 14. That is, after the groove 14 is provided behind the housing 1, the installation position of the trailer 400 on the vehicle can be moved forward a certain distance, so that the turning radius envelope 401 of the trailer 400 is at least partially located within the groove 14. When the rear end face 13 of body 1 does not have a groove 14, the distance between trailer 400 and housing 1 is relatively large without affecting the rotational movement of trailer 400. In this embodiment, after the groove 14 is provided, trailer 400 can move forward a certain distance and reduce the space occupied by hydrogen supply system 100. After trailer 400 moves forward, the increase in the wheelbase of the whole vehicle caused by the hydrogen supply system 100 on the back can be effectively shortened. Therefore, even if the hydrogen supply system 100 is set on the back of cab 300, the wheelbase of the whole vehicle can be effectively reduced.

[0041] In some embodiments, see Figure 1 and Figure 3 As shown, the groove 14 may have a first inner wall surface 141 and a second inner wall surface 142 and a third inner wall surface 143 connecting the first inner wall surface 141. The second inner wall surface 142 and the third inner wall surface 143 are respectively located on opposite sides of the first inner wall surface 141, such that the first inner wall surface 141, the second inner wall surface 142, and the third inner wall surface 143 can form the groove 14. The first inner wall surface 141 is parallel to the front end face 12, and the second inner wall surface 142 and the third inner wall surface 143 are connected to the first inner wall surface 141. The first inner wall surface 141 can be a vertical surface parallel to the front end surface 12. The second inner wall surface 142 and the third inner wall surface 143 can be located on the left and right sides of the first inner wall surface 141, respectively, and extend obliquely to the left and right sides to form an outwardly expanding groove 14. The opening of the groove 14 gradually increases, so that the concave shape of the groove 14 can just adapt to the shape of the turning radius envelope 401 of the trailer 400, thereby reducing the space occupied by the hydrogen supply system 100 while maintaining a relatively large space inside the shell 1.

[0042] Furthermore, the degree of recess in the groove 14 can be appropriately adjusted according to the different turning radii of different vehicle models, so as to shorten the overall wheelbase of the vehicle to the greatest extent possible to adapt to different systems and different vehicles.

[0043] In some alternative embodiments, see Figure 1 and Figure 2As shown, the housing 1 may also be provided with guide surfaces 15 on opposite sides of the front end face 12. That is, the two guide surfaces 15 are respectively located on the left and right sides of the front end face 12. The guide surfaces 15 are connected to the front end face 12, and the two guide surfaces 15 extend backward from the connection point with the front end face 12 and in a direction that is inclined away from each other. In this embodiment, by providing guide surfaces 15 on both sides, the airflow in front of the vehicle can be guided to the left and right sides of the vehicle through the two guide surfaces 15, which can better adapt to the low wind resistance shape of the tractor.

[0044] In some embodiments, see Figure 2 and Figure 3 As shown, the housing 1 may also include a heat dissipation cavity 16, which is separated from the hydrogen storage cavity 11 by a skin 4. A radiator 3 is installed within the heat dissipation cavity 16, thus creating separate, independent areas for the radiator 3 and the hydrogen cylinder 2 within the housing 1. The airflow from the radiator 3's fan will not affect the effectiveness of the concentration sensor inside the hydrogen storage cavity 11, and hydrogen will not enter the fan area and cause danger, thus better ensuring safety. The radiator 3 can be used to cool the vehicle's fuel cell.

[0045] Furthermore, based on the above technical solutions, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, the housing 1 may also have side surfaces 17 located on opposite sides of the front end face 12. In this embodiment, the side surfaces 17 are perpendicular to the front end face 12. Of course, in other embodiments, the position of the side surfaces 17 can be set according to actual needs, for example, it can be set to be inclined. In this embodiment, the side surfaces 17 can be connected to the aforementioned guide surface 15, that is, the guide surface 15 can be disposed between the front end face 12 and the side surfaces 17, and the guide surface 15 connects the corresponding side surfaces 17 and the front end face 12.

[0046] The side 17 may be provided with an air inlet grille 171, through which air can enter the heat dissipation cavity 16. The housing 1 has a heat dissipation cavity 16 corresponding to each of the sides 17. That is, in this embodiment, two sides 17 may be provided, distributed on the left and right sides respectively. Each side 17 corresponds to one heat dissipation cavity 16. Each heat dissipation cavity 16 is separated from the hydrogen storage cavity 11, and each heat dissipation cavity 16 contains a radiator 3. The air inlet grille 171 communicates with the corresponding heat dissipation cavity 16. The radiator 3 is arranged at an angle relative to the corresponding side 17, forming an air intake space 18 between the air intake surface of the radiator 3 and the corresponding air inlet grille 171. In this embodiment, the radiator 3 is angled, ensuring that there is a certain air intake area in front of the air intake surface of the radiator 3, and the air intake surface of the radiator 3 faces the direction of the incoming wind, better ensuring the efficiency of the radiator 3's fan.

[0047] Preferably, the two heat dissipation cavities 16 can also be spaced apart from each other, and the middle area between the two heat dissipation cavities 16 can be used for cooling circuit pipes and to place some components. Specifically, the main function of the radiator 3 in the two heat dissipation cavities 16 is to dissipate heat for the coolant, so coolant will enter and exit the heat dissipation cavities 16. The cooling circuit pipes in the two heat dissipation cavities 16 on the left and right sides can be arranged in parallel, and the pipes converge in the middle area to form two pipes, one inlet and one outlet, and then go down. In addition to the pipes, some components such as deionizers or manual valves can also be placed in the middle area.

[0048] Furthermore, the air inlet grille 171 can also be provided with an air guide structure, so that the air inlet grille 171 provided on the entire side 17 can play an effective air intake role and effectively increase the air intake volume.

[0049] In some alternative embodiments, see Figure 2 and Figure 3As shown, the housing 1 has two inclined plates 19 with the same tilt angle as the corresponding heat sink 3. The outer surfaces of the two inclined plates 19 form the groove 14. The outer surfaces of the two inclined plates 19 can be the second inner wall surface 142 and the third inner wall surface 143, respectively. One inclined plate 19, one side surface 17, and the skin 4 can form a heat dissipation cavity 16. An air outlet 5 can be provided on the inclined plate 19, and the air outlet 5 communicates with the outside. The heat sink 3 is fixed to the corresponding... Since the inclined plate 19 has the same inclination angle as the corresponding heat sink 3, the air outlet surface of the heat sink 3 can fit in close contact with the inclined plate 19, and the air outlet surface of the heat sink 3 is correspondingly set with the air outlet 5. The air blown out by the heat sink 3 can be directly blown out through the air outlet 5. Furthermore, due to the setting of the groove 14, a certain space area is also maintained behind the air outlet surface of the heat sink 3, so the air blown out by the heat sink 3 is not easily blocked, further increasing the efficiency of the heat sink 3.

[0050] See Figure 4 and Figure 5 As shown, in some other embodiments, the air outlet 5 can also be located above the groove 14, that is, not within the groove 14; the air outlet 5 can also be located on the first inner wall surface 141 of the groove 14. That is, the shape of the groove 14 and the heat dissipation cavity 16 can be changed according to different vehicle models, and the arrangement of the radiator 3 can be adjusted; the degree of concavity of the groove 14 can also be adjusted according to the size of the radiator 3 and the different turning radii of different vehicle models, so as to adapt to different systems and different vehicles and minimize the overall wheelbase.

[0051] In some embodiments, see Figure 2 and Figure 3 As shown, a guide plate 6 is also provided on one side of the side surface 17. The guide plate 6 is connected to the skin 4 and is disposed between the heat dissipation cavity 16 and the hydrogen storage cavity 11 to separate the heat dissipation cavity 16 and the hydrogen storage cavity 11. The guide plate 6 bends and extends from the air inlet grille 171 toward the corresponding radiator 3. That is, in this embodiment, two guide plates 6 can be provided, with one guide plate 6 at each heat dissipation cavity 16. The guide plate 6 can guide the air entering from the air inlet grille 171 toward the air inlet surface of the radiator 3, so that the entire air inlet grille 171 can play the role of air intake, ensuring the air intake volume of the radiator 3, while reducing wind resistance and improving the heat dissipation efficiency of the radiator 3.

[0052] In this embodiment, the hydrogen storage cavity 11 can be divided into two regions. The first region is located below the heat dissipation cavity 16, and the second region is located in front of the heat dissipation cavity 16 and above the first region. The volume of the first region is larger than that of the second region. The first region can hold four hydrogen cylinders 2, and the second region can hold two hydrogen cylinders 2. The first and second regions can be interconnected, and both regions of the hydrogen storage cavity 11 are isolated from the heat dissipation cavity 16. The radiator 3 is preferably arranged obliquely rearward at the upper rear of the housing 1 to make full use of the internal space of the housing 1 and reduce the space occupied by the hydrogen supply system 100.

[0053] In some embodiments, see Figure 2 As shown, the housing 1 may further include a cavity 7, which is disposed below the hydrogen storage chamber 11. In this embodiment, a portion of space is left below the hydrogen storage chamber 11 to accommodate other system components.

[0054] In some alternative embodiments, see Figure 2 As shown, the front end face 12 may also be provided with a hydrogen vent 121, which is connected to the hydrogen storage cavity 11. The hydrogen vent 121 allows air to flow into or out of the hydrogen storage cavity 11, increasing airflow. Furthermore, when hydrogen leaks from the hydrogen cylinder 2, the leaked hydrogen can flow out through the hydrogen vent 121.

[0055] See Figures 6 to 8 As shown, this embodiment of the invention also provides a vehicle, which may include a frame 200, a cab 300 is mounted at the front end of the frame 200, and the aforementioned hydrogen supply system 100 is also mounted on the frame 200. The hydrogen supply system 100 is arranged behind the cab 300 and above the frame 200.

[0056] The hydrogen supply system 100 may include: a housing 1, which has a hydrogen storage chamber 11 and a hydrogen cylinder 2 inside the hydrogen storage chamber 11. The housing 1 has a front end face 12 facing the cab 300 and a rear end face 13 opposite to the front end face 12. At least a portion of the rear end face 13 is recessed toward the front end face 12 to form a groove 14. When the hydrogen supply system 100 is arranged behind the cab 300, the turning radius envelope 401 of the trailer 400 is at least partially located within the groove 14.

[0057] Because the rearward indentation of the housing 1 of the hydrogen supply system 100 forms the groove 14, when the hydrogen supply system 100 is placed behind the cab 300, the turning radius envelope 401 of the trailer 400 can be at least partially located within the groove 14. That is, after the groove 14 is provided behind the housing 1, the installation position of the trailer 400 on the vehicle can be moved forward a certain distance, so that the turning radius envelope 401 of the trailer 400 is at least partially located within the groove 14. Without the groove 14 on the rear end face 13, the distance between the trailer 400 and the housing 1 is relatively large without affecting the rotational movement of the trailer 400. In this embodiment, with the groove 14 provided, the trailer 400 can move forward a certain distance and reduce the space occupied by the hydrogen supply system 100. After the trailer 400 moves forward, the increase in the overall vehicle wheelbase caused by the hydrogen supply system 100 on the back can be effectively shortened. Therefore, even if the hydrogen supply system 100 is set on the back of the cab 300, the overall vehicle wheelbase can be effectively reduced.

[0058] Furthermore, the groove 14 has a first inner wall surface 141 and a second inner wall surface 142 and a third inner wall surface 143 connecting the first inner wall surface 141. The second inner wall surface 142 and the third inner wall surface 143 are respectively located on opposite sides of the first inner wall surface 141, and the first inner wall surface 141 is parallel to the front end surface 12. The second inner wall surface 142 and the third inner wall surface 143 extend obliquely from the connection with the first inner wall surface 141 in a direction away from each other.

[0059] The hydrogen supply system 100 used in this embodiment can be any of the hydrogen supply systems 100 provided in the above embodiments, and will not be described again here.

[0060] From an overall structural perspective, compared to the rectangular box in related technologies, the hydrogen supply system 100 provided in this embodiment has a standardized shape structure with guide surfaces 15 on both sides of the front, forming chamfers on both sides, a straight side 17 in the middle, and a concave upper rear section. This structure can better adapt to the low wind resistance design of the tractor vehicle. Furthermore, the hydrogen cylinder 2 and the radiator 3 are arranged in a dispersed area inside the housing 1, which better ensures safety.

[0061] The hydrogen supply system 100 provided in this embodiment has the foundation for expansion to 70MPa, liquid hydrogen mode, and high-pressure fan radiator 3, which is conducive to subsequent iterative upgrades.
