[0003] In related technologies, fuel tanks often adopt a regular rectangular or cylindrical structure and are installed on the side of the vehicle frame. However, due to the layout of chassis components such as mounting brackets (e.g., hanger brackets), fuel tanks often face spatial interference problems during installation, resulting in a shortened fuel tank length or an increased vehicle wheelbase, which affects the vehicle's range and economy. Utility Model Content

[0004] This application provides a chassis assembly and a vehicle to solve the problem of how to avoid interference between the fuel tank and components such as mounting brackets installed on the side of the chassis.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions: In a first aspect, embodiments of this application provide a chassis assembly, which includes a chassis, a mounting bracket, and a fuel tank. The mounting bracket is connected to the chassis; the fuel tank is connected to the chassis; along the width direction of the chassis, the fuel tank and the mounting bracket are located on the same side of the chassis; the fuel tank has a clearance portion, and at least a portion of the mounting bracket is located in the clearance portion.

[0006] In some possible implementations of the first aspect, the clearance portion is located at one end of the fuel tank along the length of the frame.

[0007] In some possible implementations of the first aspect, the minimum distance L between the mounting bracket and the oil tank satisfies: 10mm≤L≤60mm.

[0008] In some possible implementations of the first aspect, the clearance portion is a groove; the groove is recessed in a direction away from the frame; at least a portion of the mounting bracket is located in the groove.

[0009] In some possible implementations of the first aspect, the depth D of the groove satisfies: 40mm≤D≤160mm; and the width W of the groove along the length of the frame satisfies: 150mm≤W≤450mm.

[0010] In some possible implementations of the first aspect, the frame assembly also includes a mounting bracket; the fuel tank is connected to the frame via the mounting bracket.

[0011] In some possible implementations of the first aspect, there are multiple fixed brackets; the two ends of the fuel tank along the length of the frame are respectively connected to the frame via fixed brackets.

[0012] In some possible implementations of the first aspect, the fuel tank has a receiving cavity; the fuel tank also includes a baffle plate disposed within the receiving cavity; any plane perpendicular to the width direction of the frame is defined as a first reference plane, and the orthographic projection of the baffle plate in the first reference plane does not overlap with the orthographic projection of the clearance portion in the first reference plane.

[0013] In some possible implementations of the first aspect, the fuel tank is made of aluminum alloy or stainless steel.

[0014] Secondly, embodiments of this application also provide a vehicle, the vehicle including: a cab and a frame assembly, the frame assembly being a frame assembly according to any of the above aspects, the cab being disposed on the frame assembly.

[0015] The chassis assembly and vehicle provided in this application have the following beneficial effects: The chassis assembly provided in this application includes a clearance section in the fuel tank to avoid interference with the mounting bracket. This allows the fuel tank to overlap with the mounting bracket, increasing its length and capacity, thereby improving the vehicle's range. Alternatively, while maintaining the same fuel tank volume, the space occupied by the fuel tank on the side of the chassis can be reduced, thus shortening the vehicle's wheelbase, improving maneuverability, and further enhancing its range.

[0031] In the design of vehicles (such as heavy trucks), the fuel tank is an important component for storing fuel or new energy power media (such as methanol, natural gas, etc.), and its placement directly affects the vehicle's wheelbase, range, and structural stability.

[0032] In related technologies, fuel tanks often adopt a regular rectangular or cylindrical structure and are installed on the side of the vehicle frame. However, due to the layout of chassis components such as mounting brackets (e.g., hanger brackets), fuel tanks often face spatial interference problems during installation, resulting in a shortened fuel tank length or an increased vehicle wheelbase, which affects the vehicle's range and economy.

[0033] To address the aforementioned issues, this application provides a chassis assembly and a vehicle. In the chassis assembly, a clearance portion is provided in the fuel tank to avoid interference with the mounting bracket. This effectively prevents interference between the fuel tank and the mounting bracket, allowing the fuel tank to overlap with the mounting bracket. This enables the fuel tank to be lengthened, increasing its capacity and thus improving the vehicle's range. Alternatively, while maintaining the same fuel tank volume, the space occupied by the fuel tank on the side of the chassis can be reduced, thereby shortening the vehicle's wheelbase, improving vehicle maneuverability, and further enhancing its range.

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0035] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the frame assembly 1 provided in some embodiments of this application; Figure 2 for Figure 1 The diagram shows a top view of the chassis assembly. An embodiment of this application provides a chassis assembly 1 including a chassis 100, a mounting bracket 200, and a fuel tank 300.

[0036] The frame 100 is the basic load-bearing structure of a vehicle (such as a heavy-duty truck), used to support the engine, transmission, cab, cargo box / superstructure, chassis components (such as mounting brackets 200), etc. The frame 100 includes two longitudinal beams 110 and multiple crossbeams 120. The two longitudinal beams 110 are parallel to each other, and the multiple crossbeams 120 are located between the two longitudinal beams 110. Each of the multiple crossbeams 120 is fixedly connected to the longitudinal beams 110 at both ends by welding or riveting. The multiple crossbeams 120 are spaced apart along the length of the longitudinal beams 110 and are parallel to each other. This arrangement helps to improve the structural strength and load-bearing capacity of the frame.

[0037] Mounting bracket 200, for example, is a mounting bracket in a leaf spring suspension system, used to provide a secure mounting point for the movable end of the leaf spring hanger or the coiled end of the leaf spring. Mounting bracket 200 is located on one side of the frame 100 along the width direction of the frame 100 (i.e., the arrangement direction of the two longitudinal beams 110). For example, mounting bracket 200 is fixedly connected to the frame 100 by fasteners such as bolts, or by welding; this application does not limit this to the following.

[0038] The fuel tank 300 is connected to the frame 100, and along the width direction of the frame 100, the fuel tank 300 and the mounting bracket 200 are located on the same side of the frame 100. The fuel tank 300 has a clearance portion 310, and at least a portion of the mounting bracket 200 is located in the clearance portion 310.

[0039] It is understandable that, since both the fuel tank 300 and the mounting bracket 200 are located on the side of the frame 100, there will inevitably be a spatial layout conflict between the fuel tank 300 and the mounting bracket 200.

[0040] In related technologies, to avoid interference between the fuel tank 300 and the mounting bracket 200, several implementation methods are typically adopted. In the first implementation, the length of the fuel tank is shortened to avoid interference; however, this reduces the vehicle's range. In the second implementation, the vehicle's wheelbase is extended, providing more installation space for the fuel tank and mounting bracket. However, extending the wheelbase reduces vehicle maneuverability and range. In the third implementation, an additional connecting structure connects the fuel tank to the frame, separating the fuel tank from the mounting bracket, thus utilizing more space in the width direction of the frame. However, the additional connecting structure increases vehicle manufacturing costs, and the fuel tank's location on the outer edge poses a safety hazard.

[0041] Therefore, to avoid the above-mentioned problems, the frame assembly 1 provided in this application provides a clearance part 310 in the fuel tank 300 to avoid interference with the mounting bracket 200. This effectively avoids interference between the fuel tank 300 and the mounting bracket 200, allowing the length of the fuel tank 300 to be increased, thereby increasing the capacity of the fuel tank 300 and thus improving the vehicle's range. Alternatively, while keeping the volume of the fuel tank 300 unchanged, the space occupied by the fuel tank 300 on the side of the frame 100 can be reduced, thereby shortening the vehicle's wheelbase, which is beneficial to improving the vehicle's maneuverability and range.

[0042] It should be noted that some embodiments of this application are mainly described using the avoidance part 310 avoiding the mounting bracket 200 as an example. However, this application is not limited to this. In other embodiments, based on similar concepts, the avoidance part 310 can also be used to avoid other components arranged on the side of the frame 100.

[0043] A plane perpendicular to the width direction of the frame 100 is defined as the first reference plane M1; a plane perpendicular to the length direction of the frame 100 is defined as the second reference plane M2. At least a portion of the mounting bracket 200 is located within the clearance portion 310, meaning that the orthographic projection of the mounting bracket 200 in the first reference plane M1 at least partially overlaps with the orthographic projection of the clearance portion 310 in the first reference plane M1, and the orthographic projection of the mounting bracket 200 in the second reference plane M2 at least partially overlaps with the orthographic projection of the clearance portion 310 in the second reference plane M2. In this way, the size of the clearance portion 310 can be adjusted according to requirements to adapt to different assembly situations, thereby improving the applicability of the frame assembly 1.

[0044] In some embodiments, see Figure 1 and Figure 2 Along the length of the frame 100, the clearance part 310 is located at one end of the fuel tank 300.

[0045] It is understandable that if the clearance part 310 is located at a non-end of the fuel tank 300, such as in the middle of the fuel tank 300, the clearance part 310 will occupy more of the volume of the fuel tank 300 and increase the manufacturing cost. Therefore, by setting the clearance part 310 at one end of the fuel tank 300, it is beneficial to reduce the impact of the clearance part 310 on the volume of the fuel tank 300, and also to reduce the manufacturing cost of the fuel tank 300 and improve the production efficiency of the fuel tank 300.

[0046] Please see Figure 3 , Figure 3 for Figure 2 The enlarged view of a portion of box A is shown. The minimum distance L between the mounting bracket 200 and the fuel tank 300 satisfies: 10mm ≤ L ≤ 60mm. For example, the minimum distance L between the mounting bracket 200 and the fuel tank 300 can be 10mm, 15mm, 30mm, 45mm, or 60mm.

[0047] It is understandable that vehicles vibrate during operation, causing relative movement between the mounting bracket 200 and the fuel tank 300. This means the distance between them will increase or decrease due to vibration. Therefore, if the minimum distance L between the mounting bracket 200 and the fuel tank 300 is less than 10mm, it will be too small, potentially causing friction or collision between them during vibrations inside the vehicle, posing a safety hazard. If the minimum distance L between the mounting bracket 200 and the fuel tank 300 is greater than 60mm, additional connecting structures (such as transition brackets) will be needed to install the fuel tank 300, resulting in an excessively large minimum distance L, placing the fuel tank 300 too far to the outside, also posing a safety hazard.

[0048] Therefore, when the minimum distance L between the mounting bracket 200 and the fuel tank 300 satisfies 10mm≤L≤60mm, it is beneficial to simplify the connection structure between the fuel tank 300 and the frame 100, reduce the manufacturing cost of the vehicle, and avoid the safety hazards caused by friction or collision between the mounting bracket 200 and the fuel tank 300, as well as the fuel tank 300 being located too far to the outside, thus improving the stability and reliability of the fuel tank 300.

[0049] It should be noted that the minimum distance L between the mounting bracket 200 and the fuel tank 300 refers to the straight-line distance between the points where the mounting bracket 200 and the fuel tank 300 are closest to each other in space.

[0050] In some embodiments, such as Figures 1 to 3 As shown, the clearance portion 310 is a groove; the groove is recessed in a direction away from the frame 100; at least a portion of the mounting bracket 200 is located in the groove. It can be understood that the groove structure facilitates processing and helps to reduce the manufacturing cost of the frame assembly 1.

[0051] In some embodiments, the cross-section of the groove is arc-shaped or trapezoidal, which allows the structure of the groove to effectively disperse stress and avoid stress concentration at sharp corners, thereby improving the reliability of the fuel tank 300.

[0052] In some embodiments, the inner contour of the groove is adapted to the shape of the mounting bracket 200, thereby minimizing the distance between the fuel tank 300 and the mounting bracket 200 while ensuring a safe distance between them. This allows the fuel tank 300 to be positioned closer to the vehicle frame 100, which in turn improves the stability and reliability of the fuel tank 300.

[0053] In some embodiments, such as Figure 3 As shown, the depth D of the groove satisfies: 40mm ≤ D ≤ 160mm. For example, the depth D of the groove can be 40mm, 50mm, 80mm, 120mm, or 160mm.

[0054] Understandably, if the groove depth D is less than 40mm, the groove will not be able to effectively avoid the mounting bracket 200, resulting in the fuel tank 300 being too close to the mounting bracket 200, which poses a safety hazard. If the groove depth D is greater than 160mm, the groove depth D is too large, which will cause the volume of the fuel tank 300 to decrease.

[0055] Therefore, when the depth D of the groove satisfies: 40mm≤D≤160mm, the groove can effectively avoid the mounting bracket 200 and avoid affecting the volume of the oil tank.

[0056] In some embodiments, such as Figure 3 As shown, the width W of the groove satisfies: 150mm ≤ W ≤ 450mm. For example, the width W of the groove can be 150mm, 200mm, 280mm, 350mm, or 450mm.

[0057] Understandably, if the width W of the groove is less than 150mm, the groove cannot effectively avoid the mounting bracket 200. In other words, the groove cannot contribute to extending the length of the fuel tank or increasing its volume. If the width W of the groove is greater than 450mm, the groove is too large, causing it to occupy too much of the fuel tank 300's volume, thus reducing the fuel tank 300's volume.

[0058] Therefore, when the width W of the groove satisfies: 150mm≤W≤450mm, the groove can effectively avoid the mounting bracket 200 and avoid affecting the volume of the oil tank.

[0059] It should be noted that the range of values ​​for the groove depth D and the groove width W can be adjusted according to the components that the fuel tank needs to avoid, and are not limited to the ranges described in the above embodiments. For example, when the fuel tank 300 needs to avoid larger or smaller components, the range of values ​​for the groove depth D and the groove width W can also be increased or decreased according to the actual situation.

[0060] Please see Figure 4 and Figure 5 , Figure 4 for Figure 2 A top view of the fuel tank 300 shown; Figure 5 for Figure 4 The diagram shows the structure of the fuel tank 300. The frame assembly 1 also includes a fixing bracket 400. The fuel tank 300 is connected to the frame 100 via the fixing bracket 400. This connection between the fuel tank 300 and the frame 100 avoids the need for additional transition brackets between the fuel tank 300 and the fixing bracket 400, or between the fixing bracket 400 and the frame 100, thus reducing the production cost of the frame assembly 1.

[0061] For example, the fixed bracket 400 is an L-shaped bracket or a ring bracket. It can be understood that L-shaped brackets and ring brackets have simple structures, mature manufacturing processes, low prices, and reliable installation, which helps to further reduce the production cost of the frame assembly 1.

[0062] The following section will take the L-shaped fixed bracket 400 as an example to introduce the structure of the fixed bracket 400. It should be noted that this should not be regarded as a limitation on the structure of the fixed bracket 400.

[0063] like Figure 1 , Figure 4 and Figure 5 As shown, the mounting bracket 400 includes a first connecting portion 410 and a second connecting portion 420. The first connecting portion 410 extends along the width direction of the frame 100, and the second connecting portion 420 extends along the height direction of the frame 100. One end of the first connecting portion 410 near the frame 100 is connected to one end of the second connecting portion along the height direction of the frame 100 (the lower end).

[0064] The first connecting part 410 is located at the bottom of the fuel tank 300 and is fixedly connected to the bottom wall of the fuel tank 300 by fasteners such as screws. For example, a shock-absorbing pad may also be provided between the first connecting part 410 and the fuel tank 300 to absorb road vibrations and engine impacts, and to compensate for slight deformation differences between the first connecting part 410 and the fuel tank 300. The second connecting part 420 is located on the side of the fuel tank 300 near the frame 100, and the second connecting part 420 is fixedly connected to the frame 100 by fasteners such as screws.

[0065] In some embodiments, the first connecting portion 410 and the second connecting portion 420 are integrally formed, that is, the first connecting portion 410 and the second connecting portion 420 are a single piece, which helps to improve the structural strength of the fixed bracket 400 and improve the assembly efficiency of the fuel tank 300 and the frame 100.

[0066] In some embodiments, the first connecting part 410 and the second connecting part 420 are connected by welding or riveting. In this way, the first connecting part 410 and the second connecting part 420 can be manufactured separately, which is beneficial to improving the production efficiency of the fixed bracket 400. Furthermore, the separate first connecting part 410 and the second connecting part 420 are easy to transport, which helps to reduce transportation costs.

[0067] In some embodiments, there are multiple fixing brackets 400. The two ends of the fuel tank 300 along the length of the frame 100 are respectively connected to the frame 100 via fixing brackets 400. This helps to improve the stability and reliability of the connection between the fuel tank 300 and the frame 100.

[0068] In some embodiments, the fuel tank 300 has a receiving cavity for containing fuel. The fuel tank 300 also includes a wave deflector (not shown) disposed within the receiving cavity. The orthographic projection of the wave deflector in the first reference plane does not overlap with the orthographic projection of the clearance portion 310 in the first reference plane. In this way, the recessed structure of the outer wall of the fuel tank 300 (i.e., the clearance portion 310) can be prevented from affecting the wave-damping function of the wave deflector.

[0069] In some embodiments, the fuel tank 300 is made of aluminum alloy to make the fuel tank 300 lighter, which facilitates assembly and processing, and helps to reduce the load on the fixed bracket 400, thereby improving the reliability and stability of the connection between the fuel tank 300 and the frame 100.

[0070] In other embodiments, the fuel tank 300 may also be made of stainless steel to give the fuel tank 300 higher strength and prevent the fuel tank 300 from being damaged.

[0071] Please see Figure 6 , Figure 6This is a block diagram of a vehicle provided in some embodiments of this application. Some embodiments of this application also provide a vehicle 1000. The vehicle 1000 includes a cab 2 and a frame assembly 1, the frame assembly 1 being the frame assembly 1 according to any of the above embodiments, and the cab 2 being disposed on the frame assembly 1.

[0072] The beneficial technical effects of the vehicle 1000 provided in this application are the same as those of the frame assembly 1 provided in this application, and will not be repeated here.
