Description

Technical Field

[0001] This utility model relates to the field of hydrogen fuel cell tractor technology, and in particular to a chassis layout structure for a hydrogen fuel cell tractor used in ports. Background Technology

[0002] With increasing environmental awareness and the development of new energy technologies, hydrogen fuel, as a clean energy source, is gradually being applied to the transportation sector. Currently, hydrogen fuel cell tractors have been introduced to ports for full-process real-world operation. The working principle of a hydrogen fuel cell tractor is mainly to use hydrogen as fuel, converting it into electricity through a hydrogen fuel cell to drive the vehicle. A hydrogen fuel cell is a device that directly converts the chemical energy of hydrogen and oxygen into electrical energy through an electrochemical reaction. The reaction process only produces water, thus exhibiting zero emissions.

[0003] Existing hydrogen fuel cell tractors, such as the one disclosed in announcement number CN113787920B, include a chassis layout structure and a hydrogen fuel cell tractor, comprising: a frame, the frame including a first beam and a second beam arranged in parallel; a cab fixed above the frame; a fuel cell engine located between the first beam and the second beam and arranged below the cab; and a hydrogen storage system fixed above the frame and arranged behind the cab, with high-pressure accessories arranged at the bottom of the hydrogen storage system.

[0004] In the above scheme, the entire hydrogen storage system is located behind the cab. To avoid interference with the trailer, the trailer needs to be moved to the rear to make way, resulting in a longer overall length of the tractor and trailer, and a larger turning radius. When operating in the port, turning is restricted, which is not conducive to operation. Utility Model Content

[0005] To address the problem that the current hydrogen storage system is located entirely behind the cab, resulting in a longer overall length of the tractor and trailer and a larger turning radius, this utility model provides a chassis layout structure for a hydrogen fuel cell tractor used in ports.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: A chassis layout for a hydrogen fuel cell tractor unit used in ports includes a frame, a cab located at the front upper part of the frame, and a front axle, a middle axle, and a rear axle arranged sequentially from front to rear on the frame. A fuel cell stack is located below the cab, and a hydrogen supply system is also installed on the frame. The hydrogen supply system includes an upper hydrogen storage assembly and a lower hydrogen storage assembly. The upper hydrogen storage assembly is located above the frame and behind the cab; the lower hydrogen storage assembly is located below the frame and between the front and middle axles. Both the upper and lower hydrogen storage assemblies include a hydrogen storage rack and three hydrogen tanks fixedly installed within the storage rack. The three hydrogen tanks are arranged along the length of the frame. The upper and lower hydrogen storage assemblies facilitate the connection between the trailer and the tractor, reduce the overall length of the trailer and tractor, decrease the turning radius, and facilitate port operations.

[0007] Preferably, longitudinal beam one and longitudinal beam two are arranged in parallel in the middle of the frame; the fuel cell stack is arranged between longitudinal beam one and longitudinal beam two.

[0008] Preferably, the steam inlet air filter of the fuel cell stack is located between the fuel cell stack and the upper hydrogen storage assembly; the fuel cell stack is connected to two radiators; the two radiators are fixedly mounted on a bracket; the bracket is fixedly mounted on the hydrogen storage rack of the upper hydrogen storage assembly; the radiators are located at the rear of the cab. This utilizes the space at the rear of the cab, saving the space below the cab, allowing for more space around the fuel cell stack to accommodate the steam inlet air filter.

[0009] Preferably, a high-voltage component is installed above the upper hydrogen storage unit; the high-voltage component includes a multi-function controller and a DC-DC controller; the high-voltage component is mounted on a mounting frame; the mounting frame is fixedly installed above the hydrogen storage rack of the upper hydrogen storage unit and below the heat sink; the high-voltage component is located on the left side of the mounting frame. The high-voltage component's placement above the upper hydrogen storage unit avoids collisions with the upper and lower hydrogen storage units due to movement, thus improving safety. The mounting frame further enhances the safety of the high-voltage component.

[0010] Preferably, two sets of first high-voltage batteries are arranged on the right side of the fixing frame; one set of second high-voltage batteries is arranged on the left side of longitudinal beam one; and another set of second high-voltage batteries is arranged on the right side of longitudinal beam two. The two sets of second high-voltage batteries are arranged between the upper hydrogen storage component and the lower hydrogen storage component. Both sets of first high-voltage batteries and both sets of second high-voltage batteries are connected to the same set of high-voltage battery air conditioners. The high-voltage battery air conditioners are arranged on the hydrogen storage rack of the lower hydrogen storage component. The high-voltage battery air conditioners are located on the left side of longitudinal beam one and behind the second high-voltage batteries. The arrangement of the first high-voltage batteries makes full use of the space within the fixing frame. The arrangement of the second high-voltage batteries makes full use of the gaps between the upper hydrogen storage component, the lower hydrogen storage component, longitudinal beam one, and longitudinal beam two, thereby improving space utilization.

[0011] Preferably, a low-voltage battery is installed above the right side of the hydrogen storage rack of the lower hydrogen storage assembly; the low-voltage battery is located on the right side of the second longitudinal beam. This makes full use of the space between the lower hydrogen storage assembly and the second longitudinal beam.

[0012] Preferably, a motor controller is installed between longitudinal beam one and longitudinal beam two; the motor controller is located in front of the middle bridge and near the lower hydrogen storage component. This fully utilizes the space in front of the middle bridge, between longitudinal beam one, longitudinal beam two, and the lower hydrogen storage component, improving space utilization.

[0013] As can be seen from the above technical solutions, the advantages of this utility model include: This solution provides a chassis layout structure for a port hydrogen fuel cell tractor. The arrangement of the upper and lower hydrogen storage components facilitates the connection between the trailer and the port hydrogen fuel cell tractor, reduces the overall length of the trailer and the port hydrogen fuel cell tractor, decreases the turning radius, and facilitates port operations. Through rational arrangement, space utilization is improved. Attached Figure Description

Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] like Figure 1-4 and Figure 6 As shown, a chassis layout structure for a hydrogen fuel cell tractor used in ports includes a frame 1. A cab 2 is located at the front upper part of the frame 1. From front to rear, the frame 1 is equipped with a front axle 101, a middle axle 102, and a rear axle 103. A fuel cell stack 3 is located below the cab 2. A first longitudinal beam 104 and a second longitudinal beam 105 are arranged parallel to each other in the middle of the frame 1. The fuel cell stack 3 is located between the first longitudinal beam 104 and the second longitudinal beam 105, and is located above the front axle 101. An air inlet filter 301 of the fuel cell stack 3 is located between the fuel cell stack 3 and the upper hydrogen storage assembly. The fuel cell stack 3 is connected to two radiators 302. The two radiators 302 are fixedly mounted on a bracket 303. The bracket 303 is fixedly mounted on the hydrogen storage rack 4 of the upper hydrogen storage assembly. The radiators 302 are located behind the cab 2, utilizing the space behind the cab 2 and saving the space below the cab 2, so that there is more space around the fuel cell stack 3 to arrange the air inlet filter 301.

[0024] In the above configuration, a hydrogen supply system is also installed on the chassis 1, which includes an upper hydrogen storage assembly and a lower hydrogen storage assembly. The upper hydrogen storage assembly is located above the chassis 1 and behind the cab 2. The lower hydrogen storage assembly is located below the chassis 1 and between the front axle 101 and the middle axle 102. Both the upper and lower hydrogen storage assemblies include a hydrogen storage rack 4 and three hydrogen tanks 5 fixedly installed within the hydrogen storage rack 4. The three hydrogen tanks 5 are arranged along the length of the chassis 1. The installation of the upper and lower hydrogen storage assemblies facilitates the connection between the trailer and the port hydrogen fuel cell tractor, reduces the total length of the trailer and the port hydrogen fuel cell tractor, decreases the turning radius, and facilitates port operations.

[0025] like Figure 2-3As shown, a high-pressure component 6 is installed above the upper hydrogen storage component. The high-pressure component 6 includes a multi-function controller 601 and a DC-DC controller 602. The high-pressure component 6 is mounted on a mounting frame 7. The mounting frame 7 is fixedly installed above the hydrogen storage rack 4 of the upper hydrogen storage component and below the heat sink 302. The high-pressure component 6 is located to the left of the mounting frame 7. The high-pressure component 6 is positioned above the upper hydrogen storage component, preventing collisions with the upper and lower hydrogen storage components due to movement, thus improving safety. The mounting frame 7 further enhances the safety of the high-pressure component 6.

[0026] A low-voltage battery 11 is installed above the right side of the hydrogen storage rack 4 of the lower hydrogen storage component. The low-voltage battery 11 is located on the right side of the second longitudinal beam 105, making full use of the space between the lower hydrogen storage component and the second longitudinal beam 105. A motor controller 12 is installed between the first longitudinal beam 104 and the second longitudinal beam 105. The motor controller 12 is located in front of the middle bridge 102 and near the lower hydrogen storage component. This fully utilizes the gaps between the first longitudinal beam 104, the second longitudinal beam 105, and the lower hydrogen storage component in front of the middle bridge 102, improving space utilization.

[0027] like Figure 3 and Figure 5 As shown, two sets of first high-voltage batteries 8 are arranged on the right side of the fixing frame 7; a set of second high-voltage batteries 9 is arranged on the left side of longitudinal beam 104; a set of second high-voltage batteries 9 is also arranged on the right side of longitudinal beam 205; the two sets of second high-voltage batteries 9 are arranged between the upper hydrogen storage component and the lower hydrogen storage component; the two sets of first high-voltage batteries 8 and the two sets of second high-voltage batteries 9 are all connected to the same set of high-voltage battery air conditioners 10; the high-voltage battery air conditioner 10 is arranged on the hydrogen storage rack 4 of the lower hydrogen storage component, on the left side of longitudinal beam 104, and behind the second high-voltage batteries. The arrangement of the first high-voltage batteries 8 makes full use of the space within the fixing frame 7. The arrangement of the second high-voltage batteries 9 makes full use of the gaps between the upper hydrogen storage component, the lower hydrogen storage component, longitudinal beam 104, and longitudinal beam 205, improving space utilization.

[0028] When in use, the height of the trailer at the connection point with the port hydrogen fuel cell tractor can be appropriately increased, or a clearance groove can be set at the front of the trailer to ensure a reduction in the total length of the trailer and the port hydrogen fuel cell tractor, thereby reducing the turning radius.
