[0022] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0023] The fuel tank assembly 1 for a natural gas vehicle according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0024] like Figures 1-4 As shown, the fuel tank assembly 1 for a natural gas vehicle according to an embodiment of the present invention includes a connecting bracket 100, a mounting base 200, a fuel tank body 300, and a pull strap 400.

[0025] The connecting bracket 100 is adapted to be mounted on the outside of the frame 10. The mounting base 200 is mounted on top of the connecting bracket 100 and extends outward toward the frame 10, forming a clearance space below the mounting base 200. The fuel tank body 300 fits against the outer peripheral surface of the mounting base 200 and is mounted on the mounting base 200. The pull strap 400 wraps around the fuel tank body 300 and the mounting base 200 and secures the fuel tank body 300 to the mounting base 200.

[0026] For example, there may be two mounting bases 200 and two pull straps 400. The mounting bases 200 are evenly distributed on both sides of the fuel tank body 300, and the pull straps 400 are fixed to the mounting bases 200 around the outer periphery of the fuel tank body 300. The fuel tank body 300 is located at the top of the frame 10.

[0027] According to an embodiment of the present invention, a fuel tank assembly 1 for a natural gas vehicle is mounted on the outside of a frame 10, with the fuel tank body 300 located on top of the frame 10. This allows the fuel tank assembly 1 to be adapted to various vehicle models and chassis structures. Different vehicle models may have different frame sizes and shapes; by mounting the fuel tank assembly 1 on the outside of the frame 10, these differences can be better accommodated, improving the versatility of the fuel tank assembly 1. The mounting base 200 extends outward from the frame 10, providing more installation position options. The installation position of the fuel tank assembly 1 can be flexibly adjusted according to the chassis layout of different vehicle models, ensuring smooth installation on the vehicle without interference with other components, thus improving the installation flexibility of the fuel tank assembly 1.

[0028] Meanwhile, the clearance space formed under the mounting base 200 reduces the use of the side space of the frame 10, and provides sufficient space for other components on the vehicle chassis (such as drive shaft, exhaust pipe, braking system, etc.), avoiding interference with other components. Within the limited chassis space, more efficient space utilization is achieved, ensuring that the fuel tank assembly 1 can be installed smoothly without taking up too much space.

[0029] Therefore, the fuel tank assembly 1 for natural gas vehicles according to the present invention has advantages such as high versatility and space saving.

[0030] In some optional embodiments of this utility model, such as Figure 4 As shown, the mounting base 200 is constructed with a fitting arc surface 201 that fits against the fuel tank body 300, and the curvature of the cross-section of the fitting arc surface 201 is at least one-quarter of the circumference of the fuel tank body 300.

[0031] The fuel tank body 300 is typically cylindrical with a smooth surface. If the mounting base 200 is flat or has a small contact area, the fuel tank is prone to slippage, loosening, or even detachment during vehicle operation due to vibration, bumps, or sudden braking. By providing a contact arc surface 201 with at least a 1 / 4 arc, the contact area between the mounting base 200 and the fuel tank body 300 is significantly increased, thereby improving the friction between them and effectively limiting the horizontal and vertical displacement of the fuel tank body 300, thus enhancing its stability. Furthermore, the contact arc surface 201 can evenly transmit supporting force along the circumference of the fuel tank body 300, avoiding stress concentration caused by point or line contact, protecting the structural integrity of the fuel tank body 300, and extending its service life.

[0032] In some optional embodiments of this utility model, such as Figure 4 As shown, the front of the fitting arc surface 201 formed by the mounting base 200 is higher than the rear. This front-high, rear-low fitting arc surface 201 makes the fuel tank more stable during installation. This structure better adapts to the shape of the vehicle chassis, providing more stable support and fixation. During vehicle operation, the fuel tank body 300 will not loosen due to vibration and impact, ensuring the safety and reliability of the fuel tank body 300.

[0033] In some optional embodiments of this utility model, a weld nut (not shown in the figure) is provided on the side of the mounting base 200 facing away from the fuel tank body 300. The mounting base 200 and the connecting bracket 100 are connected by the weld nut. The weld nut provides a reliable and stable connection, ensuring the firmness between the mounting base 200 and the connecting bracket 100, thereby improving the overall structural stability of the fuel tank assembly 1 and reducing the risk of loosening caused by vibration or impact during vehicle operation.

[0034] The welding nuts are pre-fixed on the mounting base 200, which simplifies the installation process. Technicians only need to align the brackets and tighten the screws during installation, eliminating the need for additional positioning and fixing, thus improving installation efficiency. At the same time, the welding nuts allow for easy disassembly and installation when maintaining and replacing the connecting bracket 100, reducing operational complexity and facilitating later maintenance and repair.

[0035] In some optional embodiments of this invention, the mounting base 200 is configured as a structural component formed by stamping metal sheet.

[0036] Metal sheets themselves possess high strength, and stamping further enhances their structural strength. This high-strength mounting base 200 can withstand the weight of the fuel tank body 300 and various forces generated during vehicle operation, such as vibration and impact, ensuring that the fuel tank body 300 remains stably fixed to the frame 10 under various operating conditions without loosening or deformation, thus guaranteeing the vehicle's safety and reliability. Simultaneously, the stamped metal sheet structure has excellent resistance to deformation. During vehicle operation, bumps and collisions may occur; the stamped metal mounting base 200 effectively resists these external forces, reducing the possibility of deformation and maintaining the position and orientation of the fuel tank body 300, preventing interference or damage between the fuel tank body 300 and other vehicle components due to deformation of the mounting base 200.

[0037] In some optional embodiments of this utility model, such as Figures 2-4 As shown, the mounting base 200 is constructed as a hollow structure and has a pull strap channel 202 suitable for the pull strap 400 to pass through.

[0038] The hollow mounting base 200 significantly reduces its weight compared to a solid structure. Weight reduction is crucial for improving fuel economy and vehicle performance in vehicle structures. A lighter mounting base 200 reduces the overall weight of the vehicle, thereby lowering fuel consumption and improving acceleration and handling. The cable tie channel 202 facilitates the installation and securing of the cable tie 400. The cable tie 400 is a key component for securing the fuel tank body 300. The cable tie channel 202 ensures that the cable tie 400 does not interfere with the mounting base 200 during installation, allowing it to pass smoothly and be secured in the correct position. This improves the securing effect of the cable tie 400 and ensures that the fuel tank body 300 does not loosen during vehicle operation.

[0039] In some optional embodiments of this utility model, such as Figures 2-4 As shown, the connecting bracket 100 includes a horizontal plate portion 110, a vertical plate portion 120, and a plurality of reinforcing plate portions 130. A mounting base 200 is connected above the horizontal plate portion 110. The vertical plate portion 120 is connected to the horizontal plate portion 110 on one side adjacent to the frame 10 and extends downwards; the vertical plate portion 120 is adapted to be mounted on the frame 10. The reinforcing plate portions 130 are connected to the horizontal plate portion 110 and the vertical plate portion 120, and the plurality of reinforcing plate portions 130 are arranged at intervals in the front-rear direction.

[0040] The connecting bracket 100, through the combination of the horizontal plate 110, the vertical plate 120, and multiple reinforcing plates 130, forms a robust frame structure, effectively improving its overall strength and enabling it to withstand larger loads and torques. During vehicle operation, the fuel tank body 300 is subjected to various forces, such as vibration and impact. This structure ensures that the connecting bracket 100 remains stable under these complex conditions, preventing deformation or damage.

[0041] Multiple reinforcing plates 130 are arranged at intervals along the front-to-back direction, which can effectively disperse stress concentration points. During vehicle operation, the connecting bracket 100 is subjected to various forces, which may cause stress concentration, thereby affecting the service life of the connecting bracket 100. By rationally distributing the reinforcing plates 130, stress can be dispersed over a larger area, reducing the occurrence of excessive local stress, thereby extending the service life of the connecting bracket 100.

[0042] In some optional embodiments of this utility model, such as Figure 3 As shown, in the front-rear direction, the upper width of the vertical plate portion 120 is greater than the lower width. The larger upper width of the vertical plate portion 120 provides more clearance for other components on the vehicle chassis (such as the drive shaft, exhaust pipe, braking system, etc.), ensuring that the fuel tank assembly 1 will not interfere with these components during installation, thereby improving the space utilization of the vehicle chassis. At the same time, the wider upper and narrower lower vertical plate portion 120 provides more installation and adjustment space. During installation, technicians can easily adjust the position and angle of the fuel tank assembly 1 according to the actual situation, ensuring that it can be accurately installed on the vehicle chassis while avoiding interference with other components.

[0043] In some optional embodiments of this utility model, such as Figure 3 As shown, the foremost reinforcing plate 130 is flush with the lower edge of the front side of the vertical plate 120. The rearmost reinforcing plate 130 is flush with the lower edge of the rear side of the vertical plate 120.

[0044] The reinforcing plate 130 is tightly connected to the lower edge of the vertical plate 120, forming a continuous structure. This continuity significantly enhances the structural strength and stability of the entire connecting bracket 100, enabling it to better withstand various forces from vehicle operation, such as vibration and impact, thereby reducing the risk of damage due to structural weakness. Furthermore, the flush alignment of the reinforcing plate 130 with the lower edge of the vertical plate 120 more effectively disperses stress. When the vehicle is in motion, the fuel tank assembly 1 is subjected to various forces; these forces can be evenly distributed across the entire connecting bracket 100, reducing localized stress concentration and extending the service life of the connecting bracket 100.
