[0043] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0045] Figure 1 is a structural schematic diagram of a hydrogen supply system for a vehicle provided by an embodiment of the present invention, Figure 2 : is a schematic diagram of the structure of another vehicle hydrogen supply system provided by an embodiment of the present invention. The hydrogen supply system provided by an embodiment of the present invention is suitable for small vehicles. Figure 1 Shown is a form having a frame, combined with reference Figure 1 and Figure 2 The hydrogen supply system includes a first hydrogen supply group 1 and a second hydrogen supply group 2, each of which includes at least two hydrogen cylinders 3; the vehicle includes a front area A1, a middle area A2 and a rear area A3; the first hydrogen supply group 1 and the second hydrogen supply group 2 are both located at the bottom of the vehicle, and the first hydrogen supply group 1 is located in the middle area A2, and the second hydrogen supply group 2 is located in the rear area A1.

[0046] Specifically, the hydrogen cylinders 3 in the hydrogen supply system can be dispersedly arranged in different positions of the vehicle. For example, multiple hydrogen cylinders 3 can be divided into two groups and respectively called the first hydrogen supply group 1 and the second hydrogen supply group 2. The first hydrogen supply group 1 is set in the middle area A2 of the vehicle, and the second hydrogen supply group 2 is set in the rear area A3 of the vehicle. The larger hydrogen supply system is divided into two smaller hydrogen supply groups, which are dispersedly arranged in different areas of the vehicle. It can be reasonably arranged in a smaller space to avoid all hydrogen cylinders 3 being concentrated in one position and occupying a larger space, and to avoid safety risks caused by the gathering of a large number of hydrogen cylinders 3 when hydrogen leaks. On this basis, the hydrogen cylinders 3 of the first hydrogen supply group 1 and the second hydrogen supply group 2 can be set at the bottom of the vehicle, so that the setting position of the hydrogen cylinders 3 does not occupy the space of the car compartment and does not increase the height of the vehicle, which can improve the driving experience of the driver and passengers and the overall aesthetics of the vehicle.

[0047] Among them, it is preferred to set the number of hydrogen cylinders 3 in the first hydrogen supply group 1 and the second hydrogen supply group 2 to be greater than two, and the number of hydrogen cylinders 3 in the first hydrogen supply group 1 can be set to be the same as or different from the number of hydrogen cylinders 3 in the second hydrogen supply group 2. In a preferred embodiment, the first hydrogen supply group 1 can be set to include two hydrogen cylinders 3, and the second hydrogen supply group 2 can be set to include four hydrogen cylinders 3, that is, two hydrogen cylinders 3 are set in the middle area A2 of the vehicle, and four hydrogen cylinders 3 are set in the rear area A3. In this way, the setting of each hydrogen cylinder 3 can be made not to affect the layout setting of the walking system-related structures in the middle area and the front area of ​​the vehicle bottom.

[0048] Among them, when assembling the hydrogen supply system, Figure 2 The hydrogen supply system shown is integrally assembled on the vehicle frame 4 (as shown in FIG. Figure 1 ), and then install the frame and the hydrogen supply system together on the vehicle body. Since there are many assembly parts on the vehicle body, this can solve the problem of the difficulty in assembling the hydrogen supply system.

[0049] The hydrogen supply system for a vehicle provided in an embodiment of the present invention divides a plurality of hydrogen cylinders into a first hydrogen supply group and a second hydrogen supply group, and arranges the first hydrogen supply group in the middle area of ​​the vehicle, and arranges the second hydrogen supply group in the rear area of ​​the vehicle, so that a larger hydrogen supply system is divided into two smaller hydrogen supply groups, which are dispersedly arranged in different areas of the vehicle. They can be reasonably arranged in a smaller space, avoiding that all hydrogen cylinders are concentrated in one position and occupy a larger space, and avoiding safety risks caused by the aggregation of a large number of hydrogen cylinders in the event of hydrogen leakage. On this basis, the first hydrogen supply group and the second hydrogen supply group are both arranged at the bottom of the vehicle, so that the arrangement position of the hydrogen cylinders does not occupy the space in the car and does not increase the height of the vehicle, effectively improving the driving experience of the driver and passengers and the overall aesthetics of the vehicle, and is easy to assemble.

[0050] Optional, reference Figure 1 The vehicle includes a frame 4; the hydrogen supply system also includes a long strip bracket 5; the extension direction Y of the long strip bracket 5 is perpendicular to the length direction X of the vehicle; the length direction of the hydrogen bottle 3 is parallel to the length direction X of the vehicle, and one end of the hydrogen bottle 3 is fixed on the long strip bracket 5, and the long strip bracket 5 is fixed on the frame 4.

[0051] Specifically, the length direction X of the hydrogen bottle 3 is the radial direction of the hydrogen bottle 3. The above-mentioned setting method is adopted, that is, the extension direction Y of the long strip bracket 5 is perpendicular to the length direction X of the vehicle, and the length direction of the hydrogen bottle 3 is parallel to the length direction X of the vehicle. The hydrogen bottle 3 is fixed to the frame 4 by the long strip bracket 5, and the hydrogen bottle 3 can be radially fixed. When the vehicle slows down, the hydrogen bottle 3 can be prevented from moving relative to the vehicle body along the forward direction of the vehicle due to inertia and hitting the surrounding parts, thereby improving the safety of vehicle driving. Among them, since the extension direction Y of the long strip bracket 5 is perpendicular to the length direction X of the vehicle, the hydrogen bottles 3 in the same hydrogen supply group are also arranged along the direction Y.

[0052] Optional, Figure 3 : is a schematic diagram of fixing a hydrogen cylinder provided by an embodiment of the present invention, such as Figure 3 As shown, the hydrogen supply system of the vehicle further includes a hoop 6 ; the hoop 6 is sleeved on the head of the hydrogen cylinder 3 , and the hoop 6 is fixedly connected to the long strip bracket 5 .

[0053] Specifically, the hydrogen bottle 3 can be fixed to the long strip bracket 5 by the hoop 6. The outer diameter of the head of the hydrogen bottle 3 is smaller than the outer diameter of the bottle body, and the inner diameter of the hoop 6 can be equal to the outer diameter of the head of the hydrogen bottle 3, so that the hoop 6 is adapted to the head of the hydrogen bottle 3. After the hoop 6 is sleeved on the head of the hydrogen bottle 3, the hoop 6 can be fixed to the long strip bracket 5 by bolts.

[0054] Optional, Figure 4 is a schematic diagram of the structure of a hoop provided by an embodiment of the present invention, combined with reference Figure 1 , Figure 3 and Figure 4 The hoop 6 includes a first fastener 61 and a second fastener 62, each of which includes a semi-ring portion B1 and two extension portions B2 located on both sides of the semi-ring portion B1; the extension portion B2 of the first fastener 61 and the extension portion B2 of the second fastener 62 are fixedly connected by bolts; the elongated bracket 5 includes two sub-brackets (not shown in the figure) located on both sides of the hoop 6; the two extension portions B2 of the first fastener 61 are fixedly connected to adjacent sub-brackets, and / or the two extension portions B2 of the second fastener 61 are fixedly connected to adjacent sub-brackets, respectively.

[0055] Specifically, the first fastener 61 and the second fastener 62 can be completely identical. Taking the first fastener 61 as an example, the semi-ring portion B1 and the extension portions B2 located on both sides thereof are integrally formed. The semi-ring portion B1 of the first fastener 61 and the semi-ring portion B1 of the second fastener 62 are relatively formed into a circular ring shape, so that the head of the hydrogen bottle 3 passes through the circular ring shape and can be fixed by the hoop 6. After the first fastener 61 and the second fastener 62 are sleeved on the head of the hydrogen bottle 3, the extension portions B2 of the two located on the same side fit together and are fixed by bolts, that is, the extension portions B2 of the first fastener 61 and the second fastener 62 can be provided with overlapping screw holes, so that the first fastener 61 and the second fastener 62 can be fixed by passing the bolts through the screw holes, so that the first fastener 61 and the second fastener 62 form an inseparable circular ring hoop. On this basis, the elongated bracket 5 can include two elongated sub-brackets, and it can be understood that the length extension direction Y of the two sub-brackets is perpendicular to the length direction X of the vehicle. The two sub-brackets can be respectively arranged at the positions of the extensions B2 on both sides of the semi-ring portion B1, so that the extensions B2 can be fixedly connected to the adjacent sub-brackets by bolts, thereby realizing the fixed connection between the hydrogen cylinder 3 and the long strip bracket 5. Among them, at least one of the first fastener 61 and the second fastener 62 can be provided with a screw hole for fixed connection with the sub-bracket, so that after the first fastener 61 and the second fastener 62 are fixed to each other to form a hoop 6, they are fixedly connected to the sub-bracket by bolts.

[0056] Exemplary, combined Figure 1 , Figure 3 and Figure 4 , take the example that one of the first fastener 61 and the second fastener 62 is provided with a screw hole for fixed connection with the sub-bracket, for example, only the first fastener 61 is provided with a screw hole for fixed connection with the sub-bracket. Assume that the screw hole for fixing the first fastener 61 and the second fastener 62 to each other is the first screw hole Q1, and the screw hole for fixing the first fastener 61 and the sub-bracket 51 is the second screw hole Q2. At this time, the extension length of the extension portion B2 of the second fastener 61 can be set to be smaller than the extension length of the first fastener 61, the first screw hole Q1 of the first fastener 61 and the first screw hole Q1 of the second fastener 62 overlap, the second screw hole Q2 of the first fastener 61 does not overlap with the second fastener 62, and along the extension direction X1 of the extension portion B2, the first screw hole Q1 and the second screw hole Q2 are on the same straight line, so that the width of the extension portion B2 can be reduced, which is conducive to reducing the overall width of the hoop 6.

[0057] When the first fastener and the second fastener are both provided with a second screw hole for fixing with the sub-bracket, the extension length of the extension portion of the second fastener can be the same as the extension length of the first fastener. At this time, the first screw hole of the first fastener and the first screw hole of the second fastener overlap, and the second screw hole of the first fastener and the second screw hole of the second fastener overlap. At this time, the first fastener and the second fastener can be fixed by a bolt passing through the first screw hole, and the ring hoop and the sub-bracket can be fixed by a bolt passing through the second screw hole. In another example, the first fastener and the second fastener can also be provided to include only the first screw hole, and a longer bolt can be used to fix the ring hoop to the sub-bracket while fixing the first fastener and the second fastener.

[0058] Optional, combined with reference Figure 1 and reference Figure 3 The hydrogen supply system also includes: a semi-circular bracket 7; the frame 4 includes a semi-circular fixing bracket 4a; the inner diameter of the semi-circular bracket 7 is equal to the outer diameter of the bottle body of the hydrogen bottle 3, and the inner diameter of the semi-circular fixing bracket 4a is equal to the outer diameter of the bottle body of the hydrogen bottle 3; the semi-circular bracket 7 is also fixedly connected to the semi-circular fixing bracket 4a and is sleeved on the bottle body of the hydrogen bottle 3.

[0059] Specifically, the semi-annular bracket 7 and the semi-annular fixing frame 4a form a circular ring structure relative to each other, and the inner diameter of the circular ring is equal to the outer diameter of the body of the hydrogen bottle 3, so that after the semi-annular bracket 7 and the semi-annular fixing frame 4a are engaged and fixed with each other, the hydrogen bottle 3 can be axially fixed, which can prevent the hydrogen bottle 3 from moving left and right relative to the vehicle body when the vehicle turns or moving up and down relative to the vehicle body when bumping, thereby improving the stability of the hydrogen bottle 3.

[0060] Optional, Figure 5 This is a partial structural diagram of a hydrogen supply system for a vehicle provided by an embodiment of the present invention, combined with reference Figure 3 and Figure 5 The hydrogen supply system also includes: a buffer band 8 and a spring bolt 9; the buffer band 8 is fixedly connected to the semi-annular bracket 7 through the spring bolt 9 and is sleeved on the body of the hydrogen bottle 3; the spring structure 9a in the spring bolt 9 is located on the side of the semi-annular bracket 7 away from the buffer band 8.

[0061] Specifically, the two ends of the buffer band 8 can be fixed to the two ends of the semi-circular bracket 7, respectively, and at least one end of the buffer band 8 can be fixedly connected to the semi-circular bracket 7 through the spring bolt 9. When the buffer band 8 and the semi-circular bracket 7 are fixed by the spring bolt 9, the spring structure 9a in the spring bolt 9 can be located on the side of the semi-circular bracket 7 away from the buffer band 8, so that when the vehicle bumps up and down, the buffer band 8 can protect the bottle body from collision, and the spring can release force, further playing a protective role for the hydrogen bottle 3.

[0062] Exemplarily, the semi-annular bracket 7 and the semi-annular fixing frame 4a may also be provided with a semi-annular portion and an extension portion for fixing. Assuming that the screw hole on the semi-annular bracket 7 for fixing the buffer strap 8 is the third screw hole Q3, and the screw hole on the semi-annular bracket 7 for fixing the semi-annular fixing frame 4a is the fourth screw hole Q4, then perpendicular to the extension direction X2 of the extension portion (that is, along the length direction of the bottle body of the hydrogen bottle 3), the third screw hole Q3 and the fourth screw hole Q4 may be on the same straight line, so that the buffer strap 8 and the semi-annular fixing frame 4a may be adjacently arranged along the length direction of the bottle body of the hydrogen bottle 3, and there is no need to stack them through a screw hole to increase the axial height caused by the fixation of the hydrogen bottle 3, thereby reducing the space occupancy in the height direction of the vehicle.

[0063] Optional, combined with reference Figure 1 and Figure 2 The hydrogen supply system also includes a baffle bracket 10; the baffle bracket 10 is a plate-shaped structure, and the plane of the baffle bracket 10 is parallel to the ground; the baffle bracket 10 is located between the first hydrogen supply group 1 and the second hydrogen supply group 2, and the baffle bracket 10 is fixedly connected to the frame 4.

[0064] Specifically, the baffle bracket 10 can be arranged between the first hydrogen supply group 1 and the second hydrogen supply group 2, and its plane can be parallel to the ground, which can prevent foreign objects (such as stones) on the ground from flying into the vehicle when the vehicle is driving, and can prevent the flying foreign objects from damaging the components in the vehicle (such as hydrogen pipelines). The baffle bracket 10 can be fixed to the frame 4 by multiple bolts.

[0065] Optional, Figure 6 is a schematic diagram of the structure of a baffle support provided by an embodiment of the present invention, such as Figure 6 As shown, the baffle bracket 10 includes a HMS controller 10a, a hydrogen safety valve 10b, an infrared communication controller 10c and a pressure reducing valve 10d; the HMS controller 10a, the hydrogen safety valve 10b, the infrared communication controller 10c and the pressure reducing valve 10d are all located on the side of the baffle bracket 10 facing the vehicle body.

[0066] Specifically, the control device and safety device of the hydrogen supply system can be set on the baffle bracket 10. Among them, the HMS controller 10a is at least used to control the hydrogen flow in the hydrogen supply system; the infrared communication controller 10c detects the connection signal of the hydrogen filling gun; the hydrogen safety valve 10b can be opened when hydrogen leaks to evacuate the hydrogen to prevent danger; the pressure reducing valve 10d can reduce the pressure of the hydrogen output by the hydrogen bottle 3 and then transmit it to the combustion and discharge part of the fuel cell. The HMS controller 10a, the hydrogen safety valve 10b, the infrared communication controller 10c and the pressure reducing valve 10d are all arranged on the side of the baffle bracket 10 facing the vehicle body, which can protect the above components from being damaged by foreign objects on the road surface. In this way, the baffle bracket 10 can integrate the control device and safety device of the hydrogen supply system on the basis of protecting the components inside the vehicle, without the need to set up a baffle structure or integrated board separately, which is conducive to reducing the cost of vehicle manufacturing. Among them, the layout of the HMS controller 10a, the hydrogen safety valve 10b, the infrared communication controller 10c and the pressure reducing valve 10d on the baffle bracket 10 can be set according to the design requirements. In an embodiment of the present invention, the HMS controller 10a, the hydrogen safety valve 10b, the infrared communication controller 10c and the pressure reducing valve 10d can be arranged in sequence along the length direction perpendicular to the vehicle body.

[0067] Optional, Figure 7 is a schematic diagram of a partial structure of a vehicle provided by an embodiment of the present invention, such as Figure 7 As shown, the vehicle includes a compartment (not shown in the figure); a maintenance opening 11a is provided on a floor 11 in the compartment; the maintenance opening 11a is configured to be openable and closable; the maintenance opening 11a is arranged opposite to the baffle bracket 3.

[0068] Specifically, the maintenance port 11a can be opened or closed manually, or an electric control mechanism can be provided to control the maintenance port 11a to be opened or closed. When a problem occurs in the hydrogen supply system and the safety valve 10b or the HMS controller 10a needs to be operated, the user can open the maintenance port 11a in the vehicle compartment and operate the safety valve 10b or the HMS controller 10a through the maintenance port 11a without having to get under the vehicle or lift the vehicle, thereby improving the convenience of operation and maintenance efficiency.

[0069] For example, a first hydrogen sensor 12a can be provided at the mouth of each hydrogen bottle 3, and a second hydrogen sensor 12b can be provided inside the vehicle compartment and in the front area of ​​the vehicle frame 4, so as to detect hydrogen leakage in time and ensure the driving safety of the vehicle. The hydrogen delivery pipeline L can be bound to the vehicle frame and extend through the vehicle frame to the position of the fuel cell.
