Description

Technical Field

[0001] This utility model relates to the field of fuel cell technology, specifically to mounting brackets and operating machinery. Background Technology

[0002] Fuel cell vehicles are vehicles that use the chemical reaction of hydrogen and oxygen in a fuel cell to generate electricity, which then drives an electric motor. Existing fuel cell modules typically have relatively low drive power. When these modules are used in heavy-duty trucks or other work vehicles, the drive power may not meet the requirements. Therefore, it is necessary to further develop high-power fuel cell modules to meet the full-condition operating requirements of these vehicles.

[0003] Currently, existing low-power fuel cell modules are typically installed using dedicated frames. These frames are thin and extend in a planar manner, with the fuel cell stack and related auxiliary system components all installed inside the frame. However, as the power of the fuel cell module increases, the size and weight of its stack and auxiliary systems inevitably increase. When large-power fuel cell modules, which are larger in size and weight, are installed using existing frames, there will be insufficient installation space, making it impossible to install the large-power fuel cell modules onto the vehicle body.

The space between the first and second mounting frames, as well as the space on the side and bottom of the second mounting frame, can be used for the installation of auxiliary system components. With this type of mounting frame, the fuel cell stack and auxiliary system components of the fuel cell assembly can be arranged in multiple layers through the mounting frame, which increases the installation space for auxiliary system components.

The vehicle mount can filter vibration and reduce the impact of vehicle vibration on the fuel cell stack.

[0013] In one optional embodiment, a first mounting beam is further provided between adjacent first support beams, and the mounting frame also includes a humidifier mounting base located below the first mounting frame and connected to both the first mounting beam and the second support beam.

[0014] Beneficial effects: The structure is simple and reliable.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] The following is combined with Figures 1 to 8 The following describes embodiments of the present invention.

[0040] In related technologies, the frames used to install fuel cell components are mostly cast aluminum alloy flat plate structures. After the fuel cell components are installed on the frame, they mainly extend along the length and width of the vehicle body. However, in heavy-duty truck tractors and other work vehicles, the space available for fuel cell components in the length and width directions of the vehicle body is relatively limited. This type of frame structure is not strong enough and has a small space for arrangement, making it difficult to match the installation space in work vehicles. High-power fuel cell components cannot be installed using existing flat plate frame structures, nor can the various components be laid out in horizontal space.

[0041] According to an embodiment of the present invention, in one aspect, a mounting frame is provided for an auxiliary system for mounting a fuel cell assembly, comprising: a first mounting frame 1 and a second mounting frame 2. The top of the first mounting frame 1 is provided with a first connecting component 101 for connecting with the fuel cell stack. The first mounting frame 1 has a first connecting position for connecting with components of the auxiliary system. The second mounting frame 2 is located below the first mounting frame 1 and is assembled and connected to the first mounting frame 1 by a plurality of connecting beams 3. The first mounting frame 1 has a second connecting position for connecting with components of the auxiliary system.

[0042] In the mounting frame of this embodiment, the first mounting frame 1 and the second mounting frame 2 are arranged vertically. The top of the first mounting frame 1 can be connected to the fuel cell stack through the first connecting component 101, so that the fuel cell stack does not need to occupy the installation space inside the mounting frame. The first mounting frame 1 and the second mounting frame 2 can form two open mounting platforms. The space between the first mounting frame 1 and the second mounting frame 2, as well as the space on the side and bottom of the second mounting frame 2, can be used for the installation of auxiliary system components. With this type of mounting frame, the fuel cell stack and auxiliary system components of the fuel cell assembly can be arranged in multiple layers through the mounting frame, which increases the installation space of the auxiliary system components. At the same time, the mounting frame structure is simple and occupies less space, effectively solving the problem that existing mounting frames are difficult to install high-power fuel cell assemblies.

[0043] In this embodiment, the first direction refers to Figure 1 The first direction indicated by the middle arrow, the second direction refers to... Figure 1 The "second direction" indicated by the middle arrow refers to the horizontal plane, which contains both the first and second directions. "Up" and "down" refer to... Figure 1 The middle arrows point to "up" and "down" in the "third direction," which also refers to the vehicle's height.

[0044] Specifically, since the mounting bracket of this embodiment allows the fuel cell stack and auxiliary system components to be arranged in multiple layers along a third direction, compared to the conventional flat-panel arrangement of fuel cell components, the mounting bracket of this embodiment allows the fuel cell components to occupy less horizontal space after installation, making fuller use of the space in the height direction of the vehicle and better matching the layout space in the working vehicle.

[0045] Furthermore, since the first mounting frame 1 and the second mounting frame 2 are open mounting platforms, the first mounting frame 1 and the second mounting frame 2 will not obstruct the connection positions of the components in the auxiliary system. The water pipes, air pipes, and high and low voltage wiring harness connectors in the auxiliary system are all in open space, making it easier to disassemble and assemble.

[0046] In one possible implementation, the first mounting frame 1 includes a first support beam 102 extending along a first direction and a second support beam 103 extending along a second direction. The first support beams 102 are spaced apart along the second direction, and adjacent first support beams 102 are connected by the second support beams 103. A first reinforcing beam 104 is provided between the connected first support beams 102 and second support beams 103. The first mounting frame 1 has a simple and reliable structure, and the first reinforcing beam 104 can significantly improve the overall structural strength of the first mounting frame 1, and improve the bending resistance and load-bearing capacity of the first mounting frame 1.

[0047] Specifically, there is no limitation on the number and specific form of the first support beam 102 and the second support beam 103. The number can be two, three, etc., and the structural form can be cylindrical, prismatic, or tubular, which can be flexibly selected according to the needs.

[0048] Preferably, such as Figure 1 and Figure 2 As shown, the first mounting frame 1 includes two first support beams 102 and two second support beams 103. The first support beams 102 and the second support beams 103 are tubular structures, which are lightweight and have strong bending resistance. After the first support beams 102 and the second support beams 103 are connected, they form a rectangular frame structure. The four corner positions of the frame structure are all provided with first reinforcing beams 104 to improve the stability of the frame structure.

[0049] In one possible implementation, the first connecting assembly 101 includes a first connecting structure 1011 and a second connecting structure 1012. The first connecting structure 1011 is respectively disposed at the middle position of the first support beam 102 and the second support beam 103, and the second connecting structure 1012 is disposed at the connection position between the first support beam 102 and the second support beam 103. This type of first connecting assembly 101 has more and more evenly distributed connection positions, which can make the first mounting frame 1 more reliably connected to the fuel cell stack and ensure the assembly quality of the two.

[0050] The middle position of the first support beam 102 and the second support beam 103 refers to the part between the two ends of the first support beam 102 and the second support beam 103.

[0051] Specifically, the first connecting structure 1011 and the second connecting structure 1012 are both sheet-like connecting structures with a certain thickness. Compared with the first mounting frame 1 being directly connected to the bottom surface of the fuel cell stack, adjusting the thickness of the first connecting structure 1011 and the second connecting structure 1012 can effectively compensate for the manufacturing error of the first mounting frame 1 and reduce the processing difficulty of the first mounting frame 1.

[0052] In one possible implementation, a second reinforcing beam 301 is provided between the connecting beam 3 and the first mounting frame 1, and a third reinforcing beam 302 is provided between the connecting beam 3 and the second mounting frame 2. The second reinforcing beam 301 and the third reinforcing beam 302 can effectively improve the structural strength of the mounting frame.

[0053] Specifically, such as Figure 1As shown, a connecting block 108 is also separately provided on the side wall of the first support beam 102 away from the adjacent first support beam 102. The first mounting frame 1 is connected to the connecting beam 3 through the connecting block 108. The first mounting frame 1 can extend its connection point through the connecting block 108. When the length dimension of the second mounting frame 2 along the first direction is inconsistent with the length dimension of the first mounting frame 1 along the first direction, the connecting block 108 can make up for it, thereby improving the arrangement flexibility of the connecting beam 3.

[0054] In one possible implementation, a second connecting component 105 is also provided on the side of the first mounting frame 1. The second connecting component 105 has a connection position for connecting with the vehicle mount. The mounting frame can be directly connected to the vehicle mount through the second connecting component 105. The vehicle mount can filter vibration and reduce the impact of vehicle vibration on the fuel cell stack.

[0055] Specifically, such as Figure 1 As shown, the second connecting component 105 includes a plurality of buffer seats spaced apart on the first mounting frame 1. When the buffer seats are connected to the suspension, a buffer pad 1051 is provided between the buffer seats and the suspension connector.

[0056] In one possible implementation, the second mounting frame 2 includes a third support beam 201 extending along a second direction and a fourth support beam 202 extending along a first direction, with the spaced-apart third support beams 201 connected by the fourth support beam 202.

[0057] Preferably, the second mounting frame 2 includes two third support beams 201 and one fourth support beam 202. The length of the two third support beams 201 along the second direction is greater than the interval between the two first support beams 102 along the second direction. The interval between the two third support beams 201 along the first direction is less than the length of the first support beam 102 along the first direction. One end of the two third support beams 201 along the first direction is connected by the fourth support beam 202, while the other end is in an open state. The two ends of the two third support beams 201 along the first direction are respectively fixedly connected to the corresponding connecting blocks 108 on the first support beam 102 by connecting beams 3.

[0058] In addition, the two connecting beams 3 that are far from the fourth support beam 202 are fixedly connected by the fifth support beam 303 to improve their stability.

[0059] In one possible implementation, a first mounting beam 106 is also provided between adjacent first support beams 102. The mounting frame also includes a humidifier mounting base 4, which is located below the first mounting frame 1 and is connected to the first mounting beam 106 and the second support beam 103 respectively. The structure is simple and reliable. The first mounting beam 106 can not only improve the structural strength of the first mounting frame 1, but also increase the available placement positions on the first mounting frame 1. The humidifier can be installed below the first mounting frame 1 through the humidifier mounting base 4.

[0060] The structural form of the first mounting beam 106 is not limited; it can be a member with an L-shaped, I-shaped, or U-shaped cross-section, and can be flexibly selected.

[0061] In one possible implementation, a second mounting beam 107 is also provided between adjacent first support beams 102. The mounting frame also includes a water pump mounting seat 5, which is connected to the bottom of the first mounting beam 106 and the second mounting beam 107 respectively. The structure is simple and reliable. The second mounting beam 107 can not only improve the structural strength of the first mounting frame 1, but also increase the available placement positions on the first mounting frame 1. The water pump can be installed below the first mounting frame 1 through the water pump mounting seat 5.

[0062] The structural form of the second mounting beam 107 is not limited; it can be a member with an L-shaped, I-shaped, or U-shaped cross-section, and can be flexibly selected.

[0063] A second mounting beam 107 is also provided between adjacent first support beams 102. The mounting frame also includes an air compressor mounting base 6. The air compressor mounting base 6 is connected to the second mounting beam 107 and the second support beam 103 on the side of the second mounting beam 107 away from the first mounting beam 106. The structure is simple and reliable. The air compressor can be installed below the first mounting frame 1 through the air compressor mounting base 6.

[0064] In one possible implementation, the mounting bracket further includes a thermostat mounting base 7 and a thermostat bracket 8. The thermostat mounting base 7 is located below the first mounting frame 1 and is assembled and connected to the first support beam 102. The thermostat bracket 8 is located below the thermostat mounting base 7 and is assembled and connected to the second mounting frame 2. The thermostat can be fixed in position by both the thermostat mounting base 7 and the thermostat bracket 8. The structure is simple and reliable, and can improve the installation stability of the thermostat.

[0065] In one possible implementation, the mounting bracket further includes a valve body bracket 9, which is located below the first mounting frame 1 and is assembled and connected to the first support beam 102. The valve body of the auxiliary system can be installed below the first mounting frame 1 through the valve body bracket 9.

[0066] In one possible implementation, the mounting frame further includes a wire harness bracket 10, which is located below the first mounting frame 1 and connected to the connecting beam 3. The wire harness bracket 10 can effectively constrain the wire harness when connecting components in the auxiliary system, prevent the wire harness from rubbing or colliding with external components and thus improve the reliability of the wire harness arrangement.

[0067] And / or, the mounting frame also includes a pipe support 11, which is located below the first mounting frame 1 and is assembled and connected to the second support beam 103. The pipe support 11 can not only support the pipes in the auxiliary system, but also constrain the swing of the pipes, thereby improving the reliability of the pipe layout.

[0068] In one possible implementation, the mounting bracket further includes an intercooler mounting base 12, which is located below the second mounting frame 2 and connected to the second mounting assembly. The intercooler can be mounted below the second mounting frame 2 via the intercooler mounting base 12.

[0069] Specifically, such as Figure 5 As shown, there are multiple intercooler mounting bases 12, which are spaced apart at the bottom of the third support beam 201 of the second mounting frame 2.

[0070] In one possible implementation, the mounting bracket further includes a gas-water separator mounting base 13, which is located on one side of the second mounting frame 2 in the first direction. The gas-water separator mounting base 13 is assembled and connected to the side wall of the second mounting frame 2. This arrangement of the gas-water separator mounting base 13 allows the gas-water separator to make fuller use of the space on one side of the second mounting frame 2 in the first direction.

The mounting base and bracket can be plate-shaped, rod-shaped, block-shaped, etc., as long as the corresponding component can be installed.
