Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and in particular relates to a vehicle-mounted hydrogen system and a new energy vehicle. Background Art

[0002] As the refueling, storage, and supply device for fuel cell vehicles, the onboard hydrogen system is a crucial component of hydrogen fuel vehicles. It provides hydrogen fuel at a stable pressure to the fuel cell system, similar to the fuel tank in a traditional vehicle, ensuring the vehicle's range.

[0003] The current mainstream on-board hydrogen system is arranged at the rear side of the cab. Steel is welded into a hydrogen bottle frame, and a horizontal multi-layer stacking scheme is adopted to assemble the hydrogen bottle in the frame to form a back-type multi-layer array structure. This installation scheme of the on-board hydrogen system occupies a certain space behind the cab, and it is not convenient to use this scheme for vehicles that are sensitive to the size of the upper body. For example, for vehicles such as dump trucks and pump trucks, the rear-mounted hydrogen system solution will directly affect the size of the upper body, resulting in adverse effects such as the dump truck cargo box being compressed and the pump truck boom being moved back or shortened. In addition, the existing hydrogen bottle frame is not strong. If a multi-layer stacking method is adopted, the hydrogen bottle frame is usually required to have a higher structural strength, resulting in a heavier weight of the hydrogen bottle frame, which increases the weight of the entire vehicle.

[0009] In an embodiment of the present invention, a beam flange is provided on the lifting beam, and the beam flange at least covers the outer edges of two beam sides that are oppositely arranged along the upper side of the lifting beam in the X direction.

[0010] In an embodiment of the present utility model, the fastening mechanism includes: an arc-shaped plate, the bottom of which is fixed in the supporting arc groove, and the outer edge of the arc-shaped plate protrudes from the outer edge of the supporting arc groove; a pull strap, which is sleeved on the outside of the arc plate, and the two free ends of the pull strap fasten the hydrogen bottle to the arc plate through a connecting assembly.

[0044] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0045] The vehicle-mounted hydrogen system according to the present invention will be described below with reference to the accompanying drawings.

[0046] like Figures 1 to 4As shown, in an embodiment of the present utility model, the on-board hydrogen system 100 includes a hydrogen bottle 9, a bottom support device and a lifting beam 3. The bottom support device includes a bottom support beam 1 and a fastening mechanism 2. The bottom support beam 1 is provided with a plurality of support arc grooves for supporting the hydrogen bottle 9 at intervals along the X direction. The fastening mechanism 2 is used to fasten the hydrogen bottle 9 in the support arc groove; the lifting beam 3 extends along the Z direction, the lower end of the lifting beam 3 is connected to the bottom support beam 1, and the upper end is used to connect to the vehicle frame 200 of the new energy vehicle. Multiple lifting beams 3 are arranged in sequence along the X direction.

[0047] It should be noted that the bottom support beam 1 in this embodiment can be made of rectangular steel, with the support arc opening facing upward. In this embodiment, the X-axis can be the length of the new energy vehicle, the Y-axis can be the width of the new energy vehicle, and the Z-axis can be the height of the new energy vehicle. Each hydrogen cylinder 9 can be secured in the Y-axis direction using two spaced-apart fastening mechanisms 2.

[0048] This embodiment provides a bottom-mounted flat on-board hydrogen system 100 structural solution, which adopts a modular design and can be used as a module for the installation of multiple hydrogen bottles 9. When assembling the on-board hydrogen system 100 in this embodiment, the hydrogen bottle 9 can be fastened to the support arc groove by the fastening mechanism 2. Each support arc groove is fixed with a hydrogen bottle 9. The bottom support beam 1 can be used to support the hydrogen bottle 9 at the bottom. The hydrogen bottle 9 is arranged in a bottom-mounted flat manner to form a multi-bottle bottom-mounted flat structure. The bottom-mounted hydrogen bottle 9 fixing method makes up for the lack of upper installation space occupied by the back of the hydrogen system. Multiple hydrogen bottles 9 can be set as a module and can be increased or decreased according to different needs. The lower end of the lifting beam 3 can be connected to the outer side of the bottom support beam 1, and the upper end of the lifting beam 3 can be connected to the whole vehicle beam 200 of the new energy vehicle to form a bottom lifting method, which can further avoid affecting the upper installation space. At the same time, the hydrogen bottle 9 is hoisted by multiple hoisting beams 3, and the fastening mechanism 2 only plays the role of fastening the hydrogen bottle 9. The multiple hoisting beams 3 serve as the main support, and the structure is more stable. It can replace the existing method of only using rope fixation, improve the hoisting stability, form a weight-reducing space between the multiple hoisting beams 3, and also achieve lightweighting of the on-board hydrogen system 100. The on-board hydrogen system 100 in this embodiment can fix the hydrogen bottle 9 by bottom hoisting through the cooperation of the bottom support beam 1, the fastening mechanism 2 and the hoisting beam 3, avoiding the impact on the upper space of the new energy vehicle, while also improving the structural strength and achieving lightweighting, ensuring the system stability of the on-board hydrogen system 100.

[0049] like Figure 1 and Figure 2As shown, two bottom support beams 1 are positioned opposite each other along the Y direction, with the same number of fastening mechanisms 2 and supporting arc grooves, arranged in a one-to-one correspondence. The onboard hydrogen system 100 also includes an intermediate support beam 4, with its ends along the Y direction correspondingly connected to the two bottom support beams 1. Multiple intermediate support beams 4 are spaced apart along the X direction, and both the hoisting beam 3 and the vehicle frame 200 are connected to the intermediate support beams 4. The multiple hoisting beams 3 include side hoisting beams 3a located at the ends of the bottom support beams 1 along the X direction, and multiple intermediate hoisting beams 3b located between the side hoisting beams 3a. An intermediate support beam 4 is connected between two hoisting beams 3 that face each other along the Y direction.

[0050] In one embodiment, the on-board hydrogen system 100 includes two bottom support beams 1, four side suspension beams 3a, four middle suspension beams 3b and four middle support beams 4. When assembling the on-board hydrogen system 100 in this embodiment, first fix the four side suspension beams 3a and the four middle suspension beams 3b to the two bottom support beams 1. The fixing method can be bolt connection, welding, etc., and then connect the middle support beam 4 to the four middle suspension beams 3b and the four side suspension beams 3a respectively. The Y-direction ends of the middle support beam 4 are not only connected to the two bottom support beams 1, but also to the suspension beam 3, which can increase the strength of the system along the Y direction. At the same time, it can locate the Y-direction spacing between the two bottom support beams 1, which provides convenience for assembling the entire system onto the vehicle frame 200. In order to further increase the impact strength of the on-board hydrogen system 100 in the Y direction, the top of the middle support beam 4 can be fixed to the lower wing surface of the vehicle frame 200 by bolts.

[0051] like Figure 6 As shown, in one embodiment, the intermediate support beam 4 includes a main frame structure 41 and a support plate 42. The main frame structure 41 is provided with a hollow hole 411. Multiple support plates 42 are supported at the corners of the main frame structure 41 in a one-to-one correspondence. The support plate 42 is provided with at least two mounting planes. The bottom support beam 1, the hoisting beam 3, and the vehicle frame 200 are all connected to the main frame structure 41 via the mounting planes. The main frame structure 41 in this embodiment can be a rectangular flat frame, which adopts a frame structure with a hollow center to ensure lightweight and strength. An intermediate support beam 4 is provided between two hoisting beams 3 arranged opposite each other along the Y direction. The support plate 42 in this embodiment can be an L-shaped plate, including a horizontal mounting plane and a vertical mounting plane, which has a simple structure and is easy to assemble.

[0052] like Figure 5As shown, in one embodiment, the lifting beam 3 includes a large end portion 31, a relief portion 32, and a small end portion 33, sequentially connected from top to bottom. The large end portion 31 has a larger width along the X-axis than the small end portion 33. The relief portion 32 is provided with a relief groove 321 for accommodating the hydrogen bottle 9. An arc-shaped groove 321 is provided on the side of the lifting beam 3 facing the hydrogen bottle 9. The relief portion 32 of the middle lifting beam 3b is a small waist structure, providing strength and stability. Furthermore, the large end portion 31 is larger than the small end portion 33. The larger upper area of the large end portion 31 and the smaller lower area of the small end portion 33 improve bending resistance. The larger upper area of the small end portion 33 prevents the superstructure from bending due to external forces, while the smaller lower area of the small end portion 33 better secures it to the bottom support beam 1, reducing shaking. The larger upper area of the large end portion 31 provides a larger contact surface, helping to distribute the weight of the superstructure, reduce local pressure, and improve overall stability.

[0053] In one embodiment, two hydrogen bottles 9 form a group, and an intermediate hanging beam 3b is provided between any two adjacent groups. In another embodiment, an intermediate hanging beam 3b is provided between any two adjacent hydrogen bottles 9. In other embodiments, the number of hanging beams 3 can be increased based on actual usage requirements. The outer sides of the side hanging beams 3a are not provided with hydrogen bottles 9, and can adopt a straight-sided structure, which facilitates production and assembly.

[0054] It should be noted that the lifting beam 3 is provided with a lifting beam flange 34, which covers at least two lifting beam side edges disposed opposite each other along the X direction of the lifting beam 3. In this embodiment, the lifting beam 3 is provided with a lifting beam flange 34 on both sides along the X direction, which can improve the structural strength of the lifting beam 3. In this embodiment, the lifting beam flange 34 and the lifting beam side edges match in shape.

[0055] like Figure 2 and Figure 3 As shown, in one embodiment, the fastening mechanism 2 includes a curved plate 21 and a drawstring 22. The bottom of the curved plate 21 is fixed in the support arc groove, and the outer edge of the curved plate 21 protrudes from the outer edge of the support arc groove. The drawstring 22 is sleeved on the outside of the curved plate 21, and the two free ends of the drawstring 22 fasten the hydrogen bottle 9 to the curved plate 21 through a connecting assembly. In this embodiment, support arc grooves are cut at regular intervals on the bottom support beam 1, and curved plates 21 are welded to the support arc grooves. The hydrogen bottle 9 is placed on the curved plate 21 and fastened to the curved plate 21 via the drawstring 22 and the connecting assembly, ensuring that the hydrogen bottle 9 is securely fixed.

[0056] In this embodiment, the curved plate 21 facilitates the installation of the drawstring 22, allowing the drawstring 22 to secure the hydrogen bottle 9. The curved plate 21 is larger than the supporting arc groove, providing sufficient support area for the hydrogen bottle 9 and preventing damage to the hydrogen bottle 9 caused by increased pressure due to the groove supporting the hydrogen bottle 9. The Y-axis width of the curved plate 21 is larger than the Y-axis width of the supporting arc groove, and the X-axis length of the curved plate 21 is larger than the X-axis length of the supporting arc groove.

[0057] Specifically, the connecting assembly includes a pull rod 23 and a buffer member 25. The pull rod 23 includes a rod body 231 and a limiting portion 232 and a connecting portion 233 respectively arranged at both ends of the rod body 231. The rod body 231 passes through the two free ends, and the connecting portion 233 is connected to one of the free ends through the connecting member 24; the buffer member 25 is sleeved on the outside of the rod body 231, and the buffer member 25 is limited between the limiting portion 232 and the other free end. The free end of the drawstring 22 may be provided with a reinforcement seat 221, which may be a triangular seat. This provides installation space for the connection assembly while also reinforcing the structure of the drawstring 22. The buffer 25 may be a spring. To ensure the contact area between the limit portion 232 and the buffer 25, the connection assembly further includes two spring seats 26, which are respectively provided at both ends of the buffer 25 along the length of the buffer 25. The buffer 25 abuts the limit portion 232 through one of the spring seats 26 and abuts the reinforcement seat 221 through the other spring seat 26. The connector 24 may be a bolt, and a threaded end may be provided on the connector 233. In this embodiment, the structure of the buffer 25 in conjunction with the pull rod 23 can buffer the change in the outer diameter of the hydrogen bottle 9 caused by the expansion after filling with high-pressure gas.

[0058] In one embodiment, the on-board hydrogen system 100 further includes a bottom guard plate 5 connected to the bottom of the bottom support beam 1. The bottom guard plate 5 is provided with a reinforcing flange 51. The reinforcing flange 51 completely covers the outer edge of the bottom guard plate 5 and encloses a protective space. A plurality of hydrogen bottles 9 are accommodated in the protective space. The hydrogen bottles 9 are arranged at the lower part of the vehicle beam 200. The bottom guard plate 5 located at the bottom of the hydrogen bottles 9 can prevent the splashing of stones on the ground from damaging the surface of the hydrogen bottles 9. The bottom guard plate 5 in this embodiment can be a rectangular plate. The bottom guard plate 5 can be flanged around to form a reinforcing flange 51, which can increase the strength of the bottom guard plate 5 and also make the bottom guard plate 5 lightweight. The bottom guard plate 5 can be provided with a plurality of strip-shaped drainage holes 52 to prevent the hydrogen bottles 9 from being soaked in water.

[0059] It should be noted that the onboard hydrogen system 100 also includes a guard plate support beam 6 extending along the Y direction. Multiple guard plate support beams 6 are spaced apart along the X direction. The bottom guard plate 5 is located below the guard plate support beam 6 and connected to the bottom support beam 1 through the guard plate support beam 6. In this embodiment, the guard plate support beam 6 is welded to the outer surface of the bottom support beam 1. The bottom guard plate 5 is fixed to multiple guard plate support beams 6, which further increases the rigidity of the bottom guard plate 5. Two drainage holes 52 are provided between any two guard plate support beams 6, and the multiple drainage holes 52 are spaced apart along the X direction.

[0060] Specifically, the onboard hydrogen system 100 further includes walking casters 7 installed at the bottom of the bottom support beam 1. Installing the walking casters 7 at the bottom of the onboard hydrogen system 100 can facilitate the movement and transportation of the onboard hydrogen system 100.

[0061] In one embodiment, the on-board hydrogen system 100 also includes a bottom reinforcing beam 8 connected between the two bottom support beams 1. The bottom reinforcing beam 8 is located below the middle support beam 4 and extends along the Y direction. The two ends of the bottom reinforcing beam 8 are respectively connected to the two bottom support beams 1. A bottom support beam 1 is provided under each side suspension beam 3a, and a bottom reinforcing beam 8 is provided between any two adjacent middle suspension beams 3b.

[0062] like Figure 1 As shown, in this embodiment, the onboard hydrogen system 100 includes six hydrogen bottles 9. Two bottom support beams 1 are arranged opposite each other along the Y direction. Each bottom support beam 1 is connected to the vehicle frame 200 via multiple lifting beams 3. A plurality of intermediate support beams 4 are arranged at intervals along the X direction on top of the two bottom support beams 1. A lifting beam 3 is connected to each end of the intermediate support beam 4 in the Y direction, and the top of the intermediate support beam 4 is connected to the vehicle frame 200. The bottom support of the bottom support beam 1 allows the six hydrogen bottles 9 to form a bottom-laying structure. The multiple lifting beams 3 and multiple intermediate support beams 4 are connected to the vehicle frame 200, serving as the main support structure, which can improve the lifting strength and stability.
