[0027] The embodiments of this utility model are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.
[0028] The following is for reference. Figures 1-3 The vehicle frame assembly 100 according to an embodiment of the present utility model can centrally arrange the air tank 2 inside the longitudinal beam 11, thereby avoiding interference of the air tank 2 and the brake cable bundle with the battery box arrangement.
[0029] Combination Figures 1-3 As shown, the vehicle frame assembly 100 according to the first aspect of this utility model includes a frame 1 and an air reservoir 2. The frame 1 is the main supporting structure of the vehicle, providing support for components such as the suspension system and transmission system. It also absorbs impact energy during a collision, protecting the safety of the passenger compartment, and serves as a mounting base for related components. The air reservoir 2 is typically used to store compressed air, which can provide power to systems requiring compressed air, such as the vehicle's braking system and air suspension system.
[0030] Specifically, the frame 1 includes two longitudinal beams 11 spaced laterally, which extend longitudinally along the vehicle and can transmit and distribute loads from the body, engine and other components. The two longitudinal beams 11 define an accommodating space, and an air reservoir 2 is connected to the longitudinal beams 11 and located within the accommodating space.
[0031] Specifically, a space is defined between two longitudinal beams 11 spaced laterally. The air tank 2 is connected to the longitudinal beams 11 as a whole, and the air tank 2 is arranged inside the space. In this way, the air tank 2 can be arranged on the inner side of the longitudinal beams 11. Compared with the traditional air tank (that is, the air tank is suspended under the battery box on the outside of the longitudinal beam. When the vehicle adds a battery option, the air tank and the brake tube bundle connected to the air tank need to be arranged in a new way to match the lithium battery), the arrangement of the air tank 2 in this case can avoid interference from the battery box arrangement, thereby improving the rationality and practicality of the spatial arrangement of the air tank 2.
[0032] In addition, the air tank 2 is arranged inside the longitudinal beam 11, which reduces the probability of it being hit by external impact, thereby improving the protection of the air tank 2 and extending its service life.
[0033] Therefore, by setting up the frame assembly 100, the air tank 2 can be centrally arranged inside the longitudinal beam 11, thereby avoiding interference from the battery box arrangement on the air tank 2 and brake cable bundle, and thus improving the rationality and practicality of the air tank 2 arrangement.
[0034] According to some optional embodiments of the present invention, combined with Figure 1 and Figure 2 As shown, the length direction of the gas storage cylinder 2 is the same as the extension direction of the longitudinal beam 11.
[0035] Specifically, the air storage cylinder 2 is arranged in the same direction as the longitudinal beam 11, that is, the air storage cylinder 2 also extends longitudinally. This arrangement allows the air storage cylinder 2 and the longitudinal beam 11 to be connected more tightly, and also increases the contact range between the air storage cylinder 2 and the longitudinal beam 11 as much as possible. This makes the load of the air storage cylinder 2 more evenly distributed on the longitudinal beam 11, reduces the problem of local stress concentration, improves the fatigue durability of the air storage cylinder 2, and simplifies the installation process, reducing complex connection and fixing steps.
[0036] In addition, the air tank 2 is arranged in the same direction as the longitudinal beam 11. Compared with the air tank and longitudinal beam being arranged in opposite directions, it can reduce the protrusion at the bottom of the vehicle to a certain extent, thereby reducing wind resistance and improving fuel economy. It can also reduce the risk of collision between the vehicle and the ground or other obstacles during driving, thus improving driving safety. It can also optimize the airflow at the bottom of the vehicle, reduce turbulence, and improve driving stability.
[0037] According to some optional embodiments of the present invention, combined with Figure 1 and Figure 2 As shown, there are multiple air tanks 2, including a front axle air tank 21 and a rear axle air tank 22. The rear axle air tank 22 and the front axle air tank 21 are arranged laterally at intervals. The front axle air tank 21 and the rear axle air tank 22 are respectively connected to the longitudinal beams 11 on the corresponding sides.
[0038] The front axle air reservoir 21 primarily supplies air to the front axle braking system, while the rear axle air reservoir 22 primarily supplies air to the rear axle braking system. Each air reservoir supplies air to its respective system, thus avoiding the risk of the entire system failing due to a single air reservoir malfunction, thereby improving the reliability of the braking system. Furthermore, the front axle air reservoir 21 and rear axle air reservoir 22 can accommodate both lead-acid and lithium battery configurations in the vehicle layout.
[0039] In addition, the front axle air tank 21 and the rear axle air tank 22 are respectively connected to the longitudinal beams 11 with transverse spacing, which can improve the regularity and simplicity of the arrangement of the front axle air tank 21 and the rear axle air tank 22.
[0040] Specifically, in combination Figure 1 and Figure 2 As shown, the frame 1 also includes a plurality of longitudinally spaced crossbeams 12, which are connected between the longitudinal beams 11. Two adjacent crossbeams 12 and two transversely spaced longitudinal beams 11 together define the arrangement space 13; wherein, the front axle air tank 21 and the rear axle air tank 22 are both located within the arrangement space 13.
[0041] It is understandable that the crossbeams 12 are spaced apart in the longitudinal direction (i.e., the front-to-back direction of the vehicle), and the longitudinal beams 11 are spaced apart in the transverse direction (i.e., the left-to-right direction of the vehicle). The crossbeams 12 and the longitudinal beams 11 are connected to each other and together form a closed force-bearing frame. This allows the crossbeams 12 and the longitudinal beams 11 to form a closed force transmission path, which helps to distribute the loads they receive and thus effectively improves the structural reliability of the frame 1. On the other hand, it can also define the arrangement space 13 for arranging components, so as to facilitate the inclusion of the front axle air tank 21 and the rear axle air tank 22 in the arrangement space 13, thereby solving the problem that the front axle air tank 21 and the rear axle air tank 22 have no arrangement space 13 outside the longitudinal beams 11.
[0042] Furthermore, combined Figures 1-3 As shown, the frame assembly 100 also includes an air tank bracket 3, which is connected between the longitudinal beam 11 and the air tank 2 to connect the air tank 2, the air tank bracket 3 and the longitudinal beam 11 into a whole.
[0043] The gas storage cylinder support 3 can establish an indirect connection between the gas storage cylinder 2 and the longitudinal beam 11, making them a whole and thus improving the overall structural consistency and reliability of the three. In addition, the longitudinal beam 11 can also provide structural protection for the gas storage cylinder 2, thereby enhancing the safety of the gas storage cylinder 2.
[0044] Specifically, in combination Figures 1-3As shown, the gas cylinder support 3 includes a connecting end 31 and a guiding end 32. The connecting end 31 is connected to the inner side of the longitudinal beam 11, and the guiding end 32 is adapted to be connected to the fastener 23 that secures the gas cylinder 2. The guiding end 32 is connected to the connecting end 31, and a guiding surface 321 is formed on the side of the guiding end 32 facing the gas cylinder 2. The guiding surface 321 is at least partially bent, and the guiding surface 321 selectively conforms to a portion of the outer peripheral surface of the gas cylinder 2. For example, the fastener 23 can be a cable tie or a band, but is not limited to these.
[0045] It is understandable that the connecting end 31 can serve as a structural component connecting the longitudinal beam 11 to the gas storage cylinder support 3, and the guiding end 32 can guide the outer circumferential surface of the gas storage cylinder 2 so that the gas storage cylinder 2 can be fitted and arranged on the guiding surface 321 of the guiding end 32, thereby increasing the contact area between the gas storage cylinder 2 and the gas storage cylinder support 3, and thus improving the connection strength and stress uniformity of the two.
[0046] The guide surface 321 is at least partially bent, which makes it easier to match the outer periphery of the gas cylinder 2 (usually cylindrical), thereby improving the tightness of the connection between the gas cylinder support 3 and the gas cylinder 2.
[0047] Furthermore, combined Figures 1-3 As shown, the connecting end 31 includes a connecting plate 311 and a side plate 312. The connecting plate 311 has mounting holes 3111 spaced apart. A fastener passes through the mounting holes 3111 and is fixedly connected to the longitudinal beam 11. The side plate 312 is bent and connected between the connecting plate 311 and the guide end 32, and the side plate 312 extends toward the inside of the receiving space. For example, the fastener can be a bolt, but is not limited thereto.
[0048] In other words, the fasteners, through the mounting holes 3111, connect the connecting plate 311 and the longitudinal beam 11 into a single unit. This increases their weight and spatial modality, thereby improving their structural strength and bending / torsional stiffness. Furthermore, the gas cylinder support 3 is bolted to the longitudinal beam 11. Compared to other connection methods, this embodiment facilitates the disassembly and maintenance of the gas cylinder support 3, improving ease of assembly and disassembly and reducing subsequent maintenance costs.
[0049] For example, the longitudinal beam 11 has mating holes corresponding to the mounting holes 3111. The fastener passes through the two holes of the longitudinal beam 11 and the air tank bracket 3, connecting the longitudinal beam 11 and the air tank bracket 3 into a whole. The installation position of the air tank bracket 3 can be adjusted according to the layout requirements of different vehicle models to ensure that the layout of the air tank 2 meets the requirements of the whole vehicle.
[0050] Specifically, in combination Figures 1-3As shown, the guide end 32 includes a guide plate 322 and a flange 323. The guide plate 322 is bent and connected to the side plate 312. The flange 323 is bent and connected to the side of the guide plate 322 away from the side plate 312. The flange 323 extends toward the connecting plate 311. The flange 323, the guide plate 322 and the side plate 312 together define a limiting groove. The limiting groove is limited and engaged with the fastener 23.
[0051] Understandably, the guide plate 322 changes the extension direction of the side plate 312, and the guide plate 322 forms a guide surface 321 on the side facing the air tank 2. The flange 323 changes the extension direction of the guide plate 322, and the flange 323 extends towards the connecting plate 311. This facilitates the smooth placement of the fastener 23 in the limiting groove, and also limits the fastener 23, avoiding the risk of the fastener 23 slipping off the air tank bracket 3, thereby improving the connection stability between the air tank bracket 3 and the air tank 2.
[0052] Furthermore, combined Figures 1-3 As shown, the guide surface 321 is constructed as an arc surface, which can better fit the outer contour of the gas storage cylinder 2, thereby increasing the contact area between the gas storage cylinder support 3 and the gas storage cylinder 2. It can also evenly transfer the stress from the gas storage cylinder 2 to the gas storage cylinder support 3, avoiding the formation of stress concentration areas in the gas storage cylinder 2 during the connection process with the gas storage cylinder support 3. This effectively improves the uniformity of the force on the gas storage cylinder 2, and further improves the connection stability and reliability between the gas storage cylinder support 3 and the gas storage cylinder 2.
[0053] Optionally, the connecting end 31 and the guiding end 32 are integrally formed. Compared with the two being assembled separately, the integral forming process can improve the overall structure and structural strength of the two, thereby improving the structural reliability of the gas storage cylinder support 3. The gas storage cylinder support 3 is a sheet metal support, and the metal material has greater structural strength and rigidity, which can improve the structural reliability of the gas storage cylinder support 3.
[0054] Alternatively, the air tank bracket 3 can be made of Q355 steel with a thickness of 3mm. This arrangement can ensure the structural strength of the air tank bracket 3 while achieving a lightweight design. Moreover, this design can effectively reduce the increase in vehicle cost caused by the development of the air tank bracket 3, thereby reducing system development costs.
[0055] According to the second aspect of the present invention, the vehicle includes the frame assembly 100 of the above embodiment. Thus, the vehicle having the frame assembly 100 can centrally arrange the air tank 2 inside the longitudinal beam 11, thereby avoiding interference of the air tank 2 and the brake cable bundle with the battery box arrangement scheme, thereby improving the rationality and practicality of the arrangement of the air tank 2.
