Description

Technical Field

[0001] This invention relates to the field of hydrogen fuel cell vehicle technology, and more particularly to a frame structure and a hydrogen fuel cell tractor. Background Technology

[0002] Currently, the country is vigorously promoting the development of new energy vehicle technology. Compared with pure electric vehicles, hydrogen fuel cell vehicles have advantages such as longer driving range and shorter refueling time, making them a key focus for future new energy vehicle development. Many companies are also gradually and actively investing in the hydrogen fuel cell industry. In hydrogen fuel cell tractors, the hydrogen storage system is typically mounted on the chassis behind the cab, and a certain distance is maintained between the hydrogen storage system and the cab to avoid interference.

[0003] Patent CN214356314U discloses a fuel cell tractor, comprising a frame, a cab, a fuel cell system, a drive motor assembly, and multiple power batteries. The frame includes longitudinal beams. The cab is located at the end of the frame and has a lower engine compartment. The fuel cell system includes multiple fuel cells, a hydrogen supply system, and a cooling system. The fuel cells are located within the engine compartment and on the inner side of the frame. The hydrogen supply system includes multiple hydrogen cylinders and a hydrogen management system. The hydrogen cylinders are located on the upper side of the longitudinal beams and near the cab. The cooling system is located on the outer side of the frame and near the engine compartment. The drive motor assembly is located on the inner side of the frame and near the fuel cells and the cooling system. The power batteries are located on the outer side of the frame and near the cooling system on the side away from the engine compartment.

[0004] However, the intake and exhaust systems of the aforementioned existing fuel cell systems are located in front of the hydrogen supply system, that is, between the hydrogen supply system and the cab. Due to limited space, the cab needs to be partially recessed to accommodate the intake and exhaust systems, resulting in a smaller internal volume of the cab. Summary of the Invention

[0005] In view of this, it is necessary to provide a frame structure for a hydrogen-powered tractor to solve the technical problem that in the prior art, the intake and exhaust systems of the fuel cell system are located in front of the hydrogen supply system, that is, between the hydrogen supply system and the cab. Due to limited space, the cab needs to be partially recessed to accommodate the intake and exhaust systems, which results in a smaller internal volume of the cab.

[0006] This invention provides a frame structure for a hydrogen-powered tractor, the frame structure of which includes:

[0007] Frame;

[0008] The driver's cab is located at the front of the vehicle frame;

[0009] A hydrogen storage cabinet is provided on the vehicle frame. The driver's cab and the hydrogen storage cabinet are spaced apart from front to back. The hydrogen storage cabinet has a front cabinet panel located on the front side. A first gap and a second gap are formed between the front cabinet panel and the driver's cab. The first gap and the second gap are arranged from the middle of the vehicle frame to the side of the vehicle frame. The second gap is gradually widened rearward in a direction away from the middle of the vehicle frame, so that the second gap is larger than the first gap.

[0010] An air filter intake duct is located within the second gap and is disposed on the front panel. The air filter intake duct is used to connect to a filter disposed on the vehicle frame.

[0011] Optionally, the front panel includes a first side panel and two second side panels. The two second side panels are located on the left and right sides of the first side panel and are connected to the first side panel. The gap between the first side panel and the cab constitutes the first gap, and the gap between the second side panel and the cab constitutes the second gap. Each second side panel is gradually tilted backward in a direction away from the first side panel, and the air filter intake duct is located on one of the second side panels.

[0012] Optionally, the frame structure of the hydrogen-powered tractor also includes two extension plates, which correspond one-to-one with the two second side plates. Each extension plate is located on the side of the hydrogen storage tank and extends forward to cover part of the opening on the side of the second gap. The extension plate corresponding to the second side plate with the air filter intake duct is provided with an opening, which is provided with the air filter intake duct.

[0013] Optionally, the upper end of the extension plate is bent toward the middle of the frame.

[0014] Optionally, the frame structure of the hydrogen-powered tractor also includes an auxiliary water tank, which is located in another second gap and disposed on another second side plate.

[0015] Optionally, the frame structure of the hydrogen-powered tractor also includes multiple hydrogen storage cylinders, which are arranged from top to bottom in the hydrogen storage cabinet. Each hydrogen storage cylinder has rounded ends on both sides, and the end of each hydrogen storage cylinder corresponds to the second side plate.

[0016] Optionally, the frame structure of the hydrogen-powered tractor also includes a saddle, which is located on the frame and behind the hydrogen storage tank. The saddle is used for the trailer to be rotated and installed along the vertical axis.

[0017] Optionally, the frame structure of the hydrogen-powered tractor also includes a spoiler, which is located on the rear side of the hydrogen storage tank and between the hydrogen storage tank and the saddle.

[0018] Optionally, the spoiler includes a top spoiler and two side spoilers. The top spoiler is located above the rear side of the hydrogen storage tank and is gradually inclined upward from front to back. The two side spoilers are located on the left and right sides of the hydrogen storage tank, respectively. Each side spoiler is gradually inclined away from the center of the vehicle frame from front to back, and the upper end of each side spoiler is connected to the top spoiler.

[0019] Optionally, the rear fascia of the driver's cab is vertically oriented.

[0020] In addition, the present invention also provides a hydrogen-powered tractor vehicle, which includes the frame structure of a hydrogen-powered tractor vehicle as described in any of the above technical solutions.

[0021] Compared with existing technologies, the hydrogen-powered tractor frame structure provided by this invention features a cab and a hydrogen storage tank spaced apart from front to back. The first gap is the minimum safe gap between the cab and the hydrogen storage tank. The air filter intake duct is located within the second gap, which is relatively large, providing ample space for the installation of the air filter intake duct and ensuring its normal operation. Furthermore, the overall gap between the cab and the hydrogen storage tank is the minimum safe gap, resulting in a compact frame structure with more space for trailer installation. The second gap is also sufficiently large, eliminating the need for a partial recess in the cab to accommodate the air filter intake duct, thus increasing the cab's volume and improving the user experience.

[0022] Since the air filter intake duct is located on the hydrogen storage cabinet, which is fixedly mounted on the vehicle frame, and the filter is also fixedly mounted on the vehicle frame, the air filter intake duct and the filter are relatively fixed. Therefore, there is no need to set up a flexible docking sealing structure. The air filter intake duct can be directly connected to the filter, which is firm, simple in structure, and reduces costs.

[0023] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it according to the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Detailed Implementation

[0035] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0036] Please see Figure 1The present invention also provides a hydrogen-powered tractor 200, which includes the frame structure 100 of the hydrogen-powered tractor as described above.

[0037] Please see Figures 1 to 4 The frame structure 100 of this hydrogen-powered tractor includes a frame 1, a cab 2, a hydrogen storage tank 3, and an air filter intake duct 4. The cab 2 is located at the front of the frame 1. The hydrogen storage tank 3 is located on the frame 1, and the cab 2 and the hydrogen storage tank 3 are spaced apart from front to back. The hydrogen storage tank 3 has a front panel 31 located at the front. The front panel 31 includes a first side panel 311 and two second side panels 312. The two second side panels 312 are located on the left and right sides of the first side panel 311 and are connected to the first side panel 311. Next, the gap between the first side plate 311 and the cab 2 is the first gap 32, and the gap between the second side plate 312 and the cab 2 is the second gap 33. Each second side plate 312 is gradually inclined backward in a direction away from the first side plate 311, so that the second gap 33 is larger than the first gap 32. The air filter intake duct 4 is located in the second gap 33 and is disposed in one of the second side plates 312. The air filter intake duct 4 is used to connect to the filter disposed on the frame 1.

[0038] The hydrogen-powered tractor frame structure 100 provided by this invention has a cab 2 and a hydrogen storage tank 3 spaced apart from front to back. The first gap 32 is the minimum safe gap between the cab 2 and the hydrogen storage tank 3. The air filter intake duct 4 is located within the second gap 33. The second gap 33 is relatively large, which can fully reserve the installation space for the air filter intake duct 4 and ensure its normal use. At the same time, the overall gap between the cab 2 and the hydrogen storage tank 3 is the minimum safe gap, making the entire frame 1 structure compact and reserving more space for trailer installation. In addition, the second gap 33 is large enough that there is no need to partially recess the cab 2 to accommodate the air filter intake duct 4, which would increase the volume of the cab 2 and improve the user experience.

[0039] Since the air filter intake duct 4 is located on the hydrogen storage cabinet 3, and the hydrogen storage cabinet 3 is fixedly mounted on the vehicle frame 1, and the filter is also fixedly mounted on the vehicle frame 1, the air filter intake duct 4 and the filter are relatively fixed. Therefore, there is no need to set up an elastic docking sealing structure. The air filter intake duct 4 can be directly connected to the filter, which is firm, simple in structure, and reduces costs.

[0040] Further, in this embodiment, the front cabinet panel 31 includes a first side panel 311 and two second side panels 312. The two second side panels 312 are located on the left and right sides of the first side panel 311 and are connected to the first side panel 311. The gap between the first side panel 311 and the cab 2 constitutes the first gap 32, and the gap between the second side panel 312 and the cab 2 constitutes the second gap 33. Each second side panel 312 is gradually inclined backward in a direction away from the first side panel 311, and the air filter intake duct 4 is disposed on one of the second side panels.

[0041] It should be noted that the "forward and backward" direction refers to the front and rear direction of the vehicle, and the "left and right" direction refers to the left and right direction of the vehicle.

[0042] Please see Figures 5 to 6 It is understood that the hydrogen storage cabinet 3 is generally rectangular in shape, that is, the hydrogen storage cabinet 3 includes a front cabinet panel 31, two side cabinet panels, a rear cabinet panel, a top cabinet panel, and a bottom cabinet panel. The front cabinet panel 31 and the rear cabinet panel are spaced apart from front to back. The two side cabinet panels are spaced apart from left to right, and each side cabinet panel is connected to the front cabinet panel 31 and the rear cabinet panel respectively. The top cabinet panel is located above and is connected to the front cabinet panel 31, the rear cabinet panel, and the two side cabinet panels respectively. The bottom cabinet panel is located below and is connected to the front cabinet panel 31, the rear cabinet panel, and the two side cabinet panels respectively. The two second side panels 312 are connected to the two side cabinet panels respectively. The front cabinet panel 31, the two side cabinet panels, the rear cabinet panel, the top cabinet panel, and the bottom cabinet panel together enclose a hydrogen storage space, which is used to house the hydrogen storage cylinder 7.

[0043] Further, please see Figures 6 to 8 In this embodiment, the frame structure 100 of the hydrogen-powered tractor also includes two extension plates 5, which correspond one-to-one with the two second side plates 312. Each extension plate 5 is located on the side of the hydrogen storage tank 3 and extends forward to cover part of the opening on the side of the second gap 33. The extension plate 5 corresponding to the second side plate 312 with the air filter intake duct 4 has an opening 51, which corresponds to the air filter intake duct 4. Specifically, the connection between the extension plate 5 and the hydrogen storage tank 3 is the connection between the second side plate 312 and the side plate. The forward extension of the extension plate 5 can cover most of the opening on the side of the second gap 33. This arrangement serves two purposes: firstly, it covers the second gap 33, improving the overall aesthetics of the vehicle; secondly, it protects the air filter intake duct 4 from damage caused by flying debris during vehicle operation.

[0044] Furthermore, the frame structure 100 of the hydrogen-powered tractor also includes a grille plate, which is installed at the opening 51. The grille plate prevents foreign objects from entering the air filter intake duct 4.

[0045] Furthermore, in this embodiment, the gap between the front side of the extension plate 5 and the cab 2 is greater than or equal to the first gap 32. This arrangement can prevent the extension plate 5 from interfering with the cab 2 and affecting the normal use of the cab 2.

[0046] Furthermore, to avoid increasing the vehicle's drag during driving, please refer to... Figures 5 to 6 In this embodiment, the extension plate 5 is gradually inclined towards the middle of the frame 1 from back to front. This arrangement makes the extension plate 5 compatible with the cab 2. The cab 2 in front can shield the extension plate 5, preventing the extension plate 5 from protruding. On the one hand, this can prevent damage to the extension plate 5 during driving, and on the other hand, it can prevent increasing the resistance of the vehicle during driving.

[0047] Furthermore, in order to avoid increasing the resistance of the vehicle during driving, in this embodiment, the upper end of the extension plate 5 is bent toward the middle of the frame 1.

[0048] Further, please see Figures 6 to 8 In this embodiment, the frame structure 100 of the hydrogen-powered tractor also includes an auxiliary water tank 6, which is located within another second gap 33 and disposed on another second side plate 312. The second gap 33 provides installation space for the auxiliary water tank 6, making full use of the second gap 33 to make the entire frame 1 structure compact.

[0049] Further, please see Figure 8 In this embodiment, the frame structure 100 of the hydrogen-powered tractor also includes multiple hydrogen storage cylinders 7, which are arranged from top to bottom within the hydrogen storage cabinet 3. Each hydrogen storage cylinder 7 has rounded ends, and the ends of each hydrogen storage cylinder 7 correspond to the second side plate 312. Specifically, because the second side plate 312 is inclined, the internal space of the hydrogen storage cabinet 3 is narrower at both ends. However, because the ends of the hydrogen storage cylinders 7 are rounded, the hydrogen storage cylinders 7 can be placed inside the hydrogen storage cabinet 3, while avoiding interference between the hydrogen storage cylinders 7 and the second side plate 312, and avoiding the impact of the inclined arrangement of the second side plate 312 on the internal space of the hydrogen storage cabinet 3.

[0050] Furthermore, the frame structure 100 of the hydrogen-powered tractor also includes a saddle, which is located on the frame 1 and behind the hydrogen storage tank 3. The saddle is used for the trailer to be rotated and installed along the vertical axis.

[0051] Furthermore, most vehicles have a spoiler 9 installed on the roof. Currently, these spoilers 9 are all located above the driver's cab 2. However, due to the limited space above the driver's cab 2, the spoiler effect is poor. Please refer to [link / reference needed]. Figures 5 to 6 In this embodiment, the frame structure 100 of the hydrogen-powered tractor also includes a spoiler 9, which is located on the rear side of the hydrogen storage tank 3 and between the hydrogen storage tank 3 and the saddle. The large space between the hydrogen storage tank 3 and the saddle allows for an increase in the area of ​​the spoiler 9, thus improving the turbulence effect.

[0052] Furthermore, in this embodiment, the spoiler 9 includes a top spoiler 91 and two side spoilers 92. The top spoiler 91 is located above the rear side of the hydrogen storage tank 3, and is gradually inclined upwards from front to back. The two side spoilers 92 are located on the left and right sides of the hydrogen storage tank 3, respectively, and each side spoiler 92 is gradually inclined away from the center of the frame 1 from front to back. The upper end of each side spoiler 92 is connected to the top spoiler 91. Specifically, the top spoiler 91 is located at the connection between the top cabinet panel and the rear cabinet panel, and the side spoilers 92 are located at the connection between the side cabinet panels and the rear cabinet panel. The top spoiler 91 and the two side spoilers 92 together form a trumpet-shaped structure with a large area, which improves the spoiler effect.

[0053] Furthermore, since the trailer can rotate around the saddle, in order to avoid interference between the trailer and the spoiler 9 when the trailer rotates around the saddle, the front side of the trailer moves to form an arc-shaped trajectory when the trailer rotates around the saddle, and the two side spoilers 9 are located outside the arc-shaped trajectory. This arrangement avoids interference between the spoiler 9 and the trailer.

[0054] Furthermore, in this embodiment, the rear perimeter of the cab 2 is vertically oriented. That is, the cab 2 has a relatively regular shape with no recessed structures along its perimeter. This design ensures sufficient interior space for the cab 2, and the regular shape also simplifies the manufacturing of the cab 2's interior and reduces manufacturing costs.

[0055] It should be noted that the frame 1, the air filter intake duct 4, the saddle and the auxiliary water tank 6 are all existing technologies, and their specific structures will not be described in detail here.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
