Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a hydrogen fuel system assembly frame structure. Background Technology

[0002] The hydrogen supply system of a hydrogen fuel cell tractor is its core power source, essentially the "heart" of the vehicle. This system mainly consists of high-pressure hydrogen storage tanks and precision pressure regulating valve assemblies. Before being transported to the fuel cell via pipelines, hydrogen undergoes rigorous pressure regulation and purification to ensure the purity and pressure stability of the hydrogen entering the fuel cell stack. In the fuel cell stack, hydrogen reacts electrochemically with oxygen in the air to efficiently generate electricity to drive the motor, with the only emission being pure water. The entire system is monitored in real-time by an intelligent controller, ensuring reliability and safety under any operating conditions. This is a key technology for achieving zero-carbon transportation of heavy-duty trucks. The hydrogen fuel cell system assembly frame is used to mount the entire system onto the tractor, such as the magnesium alloy commercial fuel cell tractor hydrogen supply system frame with announcement number CN220031696U.

[0003] In existing technologies, the common practice is to first assemble the overall system frame and then design a side insertion port on the side of the system frame so that the hydrogen storage tank can be inserted from the side for installation. However, this installation method cannot use hoisting equipment to directly lift the hydrogen storage tank into the system frame. It requires manual operation to align and insert the hydrogen storage tank into the frame. The assembly process is time-consuming and labor-intensive, and it is easy to damage the overall frame structure and the outer wall of the hydrogen storage tank. Utility Model Content

[0004] In view of this, the present invention proposes a hydrogen fuel system assembly frame structure. By setting multiple stacked mounting positions and providing assembly ports on the overall outer frame, hydrogen storage tanks can be directly delivered into the frame through the assembly ports using hoisting equipment during the assembly of hydrogen storage tanks. Furthermore, for each layer of hydrogen storage tanks installed, the fixing components of the layer above can be assembled, enabling layer-by-layer assembly of the stacked hydrogen storage tanks. After assembly, a sealing frame is fixed. This configuration requires less manpower during assembly and effectively reduces the possibility of mechanical friction and collision between the hydrogen storage tanks and the system frame during assembly, thereby improving assembly efficiency and overall assembly quality.

[0005] The technical solution of this utility model is achieved as follows: This utility model provides a hydrogen fuel system assembly frame structure, including a support frame, an outer frame, and fixing components, wherein, The support frame has multiple stacked installation positions, with hydrogen storage tanks located at the installation positions and extending to the outside of the support frame at both ends; The outer frame is fixed to both sides of the upright and covers the outside of both ends of the hydrogen storage tank. The outer frame is provided with an assembly port, and a sealing frame is detachably installed at the assembly port. The assembly port is located on the outside of the uppermost installation position. There are multiple fixing components, all of which are detachably mounted on the upright. Each fixing component is installed in a corresponding position to fix the hydrogen storage tank to the upright.

[0006] Based on the above technical solutions, preferably, the support frame includes a base and columns, wherein, The number of bases is at least two, and the bases are fixed relative to each other to form a frame; There are multiple columns, each vertically fixed to the base frame. Each base has at least two columns, and the fixing components are installed on all columns of a single base.

[0007] More preferably, a reinforcing member is provided on one side of the support frame. The reinforcing member is inclined and one end is fixed to the base, and the other end is fixed to the outermost column of the base.

[0008] More preferably, the support frame further includes a reinforcing frame, which is arranged in an X shape and positioned between two adjacent bases and two adjacent columns.

[0009] Based on the above technical solutions, preferably, the fixing component includes a support member and a locking member, wherein, The support is fixed on the upright and is located at one end of the hydrogen storage tank, and is adapted to the outside of the hydrogen storage tank. The locking element is fixed to the support and fits against the outside of the hydrogen storage tank to secure the hydrogen storage tank in conjunction with the support.

[0010] More preferably, the support member is provided with an arc-shaped piece, which is attached to the outside of the hydrogen storage tank.

[0011] In a further preferred embodiment, the support member of the lowest layer of the fixing component is integrally fixed with the upright.

[0012] More preferably, all the support members are fixed to the uprights by bolts.

[0013] Based on the above technical solutions, preferably, the sealing frame is T-shaped and fixed to the outer frame with bolts.

[0014] The hydrogen fuel system assembly frame structure of this utility model has the following advantages over the prior art: (1) By setting up multiple stacked installation positions and setting up assembly ports on the overall outer frame, the hydrogen storage tank can be directly sent into the frame through the assembly port by hoisting equipment during the assembly operation of the hydrogen storage tank. Each time a layer of hydrogen storage tank is installed, the upper layer of fixed components can be assembled, realizing the layer-by-layer assembly operation of the stacked hydrogen storage tank. After the assembly is completed, the sealing frame is fixed. This setting requires less manpower during assembly and effectively reduces the possibility of mechanical hard friction and collision between the hydrogen storage tank and the system frame during the assembly process, thereby improving the assembly efficiency and improving the overall assembly quality. (2) By setting an arc-shaped piece on the support and making the arc-shaped piece fit against the outside of the hydrogen storage tank, the contact area between the support and the hydrogen storage tank is increased, which is more conducive to fixing the hydrogen storage tank. At the same time, it avoids problems such as deformation of the hydrogen storage tank caused by excessive local pressure. Correspondingly, the locking part can also adopt a similar design to improve the stability of the structure. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0018] like Figure 1-3 As shown, the hydrogen fuel system assembly frame structure of this utility model includes a support frame 1, an outer frame 2, and a fixing component 3.

[0019] The support frame 1 has multiple stacked mounting positions. The hydrogen storage tank is installed on the mounting position and extends to the outside of the support frame 1 at both ends. The support frame 1 is generally rectangular and the top is not sealed. The top is sealed by the outer frame 2. In some embodiments, the support frame 1 has three stacked mounting positions. Two hydrogen storage tanks can be installed on each mounting position. The middle of the hydrogen storage tank is connected to the support frame 1, and both ends extend to the outside of the support frame 1. The support frame 1 realizes the main load-bearing function of the hydrogen storage tank.

[0020] The outer frame 2 is fixed to both sides of the support frame 1 and covers the outside of both ends of the hydrogen storage tank. The outer frame 2 is provided with an assembly port, and a sealing frame 21 is detachably installed at the assembly port. The assembly port is located outside the uppermost installation position. In some embodiments, the structure on the outer frame 2 is mostly connected by L-shaped steel to form a frame covering both ends of the hydrogen storage tank. It should be noted that the outer frame 2 is mainly used to protect the hydrogen storage tank and support the stainless steel skin set on the outside of the frame assembly.

[0021] In some embodiments, both the support frame 1 and the outer frame 2 are assembled using bolts with pre-set mounting holes. This assembly method avoids problems such as inconsistent quality caused by welding, and at the same time eliminates the welding process, resulting in better consistency in the overall system frame assembly and further improving assembly efficiency.

[0022] There are multiple fixing components 3, all of which are detachably mounted on the support frame 1. Each fixing component 3 is installed in a corresponding position to fix the hydrogen storage tank to the support frame 1.

[0023] Since two hydrogen storage tanks need to be installed at each installation position, each fixing component 3 also needs to be able to connect two hydrogen storage tanks. In order to stably fix the hydrogen storage tanks, two fixing components 3 are set at each installation position. The two fixing components 3 are used to fix the two ends of the hydrogen storage tank respectively, so that they form a stable connection with the support frame 1.

[0024] In this embodiment, by setting multiple stacked installation positions and providing assembly ports on the overall outer frame 2, the hydrogen storage tanks can be directly fed into the frame through the assembly ports using hoisting equipment during the assembly of the hydrogen storage tanks. Furthermore, for each layer of hydrogen storage tanks installed, the fixing component 3 of the previous layer can be assembled, enabling layer-by-layer assembly of the stacked hydrogen storage tanks. After assembly, the sealing frame 21 is fixed. This setup requires less manpower during assembly and effectively reduces the possibility of mechanical friction and collision between the hydrogen storage tanks and the system frame during assembly, thereby improving assembly efficiency and overall assembly quality.

[0025] In some embodiments, the support frame 1 includes a base 11 and columns 12. There are at least two bases 11, which are fixed relative to each other to form a base frame. There are multiple columns 12, which are vertically fixed to the base frame. At least two columns 12 are provided on each base 11. The fixing component 3 is provided on all columns 12 of a single base 11.

[0026] Specifically, the number of bases 11 can be set to two, which are parallel to each other. The structure connecting the vehicle is set on the base 11, which serves as the supporting foundation for the entire frame 1. The number of columns 12 is set to six. Each base 11 has three columns 12, which are vertically set on the base 11 along the length of the base 11. Thus, the hydrogen storage tank can pass between the two columns 12 on a single base 11. For the two adjacent columns 12, there are three stacked hydrogen storage tanks, so as to set up six hydrogen storage tanks for installation. The columns 12 can be made of U-shaped steel or square steel.

[0027] To enhance the deformation resistance of the support frame 1 when the vehicle is moving, a reinforcing member 13 is provided on one side of the support frame 1. The reinforcing member 13 is inclined and one end is fixed to the base 11, and the other end is fixed to the outermost column 12 of the base 11. In this embodiment, the number of reinforcing members 13 is the same as the number of bases 11, and they correspond one-to-one. Similarly, both ends of the reinforcing member 13 are fixed with bolts.

[0028] To improve the load-bearing capacity and stability of the support frame 1, the support frame 1 also includes a reinforcing frame 14. The reinforcing frame 14 is arranged in an X shape and is located between two adjacent bases 11 and two adjacent columns 12. Specifically, the number of reinforcing frames 14 is set to five, which are respectively located between two bases 11, at the top of the four outermost columns 12, between the two middle columns 12, between the two outermost columns 12 on the front, and between the two outermost columns 12 on the back. This arrangement can effectively strengthen the structure and form a stable triangular structure with each column, effectively improving its resistance to deformation.

[0029] In some embodiments, the fixing component 3 includes a support member 31 and a locking member 32. The support member 31 is fixed on the upright 1 and is disposed on one end of the hydrogen storage tank and adapted to the outside of the hydrogen storage tank. The locking member 32 is fixed on the support member 31 and fits against the outside of the hydrogen storage tank to cooperate with the support member 31 to fix the hydrogen storage tank.

[0030] All support members 31 are fixed to the uprights 1. Considering that there are six uprights 12 in this embodiment, when arranging the support members 31, they are fixed to three parallel uprights 12 on the same plane. The support members 31 of each layer adopt the same arrangement method, so that the support members 31 support the hydrogen storage tank. The locking members 32 are fixed to the support members 31 respectively to achieve the fixation of the hydrogen storage tank.

[0031] In some specific embodiments, the support member 31 is provided with an arc-shaped piece 311, which is attached to the outside of the hydrogen storage tank. By providing the arc-shaped piece 311, the contact area between the support member 31 and the hydrogen storage tank is increased, which is more conducive to fixing the hydrogen storage tank and avoids problems such as deformation of the hydrogen storage tank caused by excessive local pressure. Correspondingly, the locking member 32 also adopts a similar design.

[0032] Between the support member 31 and the locking member 32, three sets of bolts are used for fixing. The locking member 32 is designed in an m shape so that two hydrogen storage tanks can be fixed at the same time.

[0033] In some embodiments, since the lowest support member 31 serves as the supporting foundation for the lowest hydrogen storage tank, it does not need to be assembled during the assembly of the hydrogen storage tank. The support member 31 of the lowest fixing component 3 is integrally fixed with the upright frame 1. This arrangement can reduce the number of support members 31 required during the assembly of the hydrogen storage tank, thereby further saving installation steps and improving installation efficiency. Specifically, the arc-shaped piece 311 can be directly installed onto the base 11 to form the lowest support member 31.

[0034] Except for the bottommost support member 31, all other support members 31 are fixed to the frame 1 by bolts. In another embodiment, including the bottommost support member 31, all are fixed to the frame 1 by bolts. This means that the bottommost support member 31 can be connected to the base 11 before the assembly step.

[0035] In some embodiments, the sealing frame 21 is T-shaped and is fixed to the outer frame 2 by bolts.

[0036] Specifically, the assembly opening at the top of the outer frame 2 does not necessarily have to be a complete opening. It can also be set as an opening on both sides of the top. It can be inserted from one side opening and then lowered to the required installation position from the other side with the help of hoisting. After installation, it can be sealed with two T-shaped sealing frames 21. Alternatively, the top of the outer shell 2 can be set as a complete opening, and it can be directly inserted from the top by hoisting equipment. After insertion, the top can be sealed with sealing frames 21.

[0037] Furthermore, traditional steel welded beams are prone to welding deformation due to their numerous components, making it difficult to guarantee welding precision. Additionally, the steel material contributes to their weight. In contrast, this embodiment directly utilizes 700L automotive beam steel plates, assembling the entire frame with bolts. This reduces the number of components and significantly decreases the number of frame welds. Fewer welds effectively reduce welding deformation, greatly improving frame manufacturing precision while achieving substantial weight reduction. Compared to traditional steel welded beam structures, this embodiment achieves a lightweight and high-quality configuration for the main frame of the tractor's hydrogen supply system.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
