Description

Technical Field

[0001] This utility model relates to the field of fuel tank assembly technology, and in particular to a fuel tank assembly. Background Technology

[0002] The fuel tank assembly is an indispensable and complete functional unit of the automotive fuel supply system, consisting of the fuel tank body, fuel pump assembly, fuel level measuring device, venting system, inlet and outlet fuel lines and interfaces, and auxiliary accessories. The fuel tank body is the core of the fuel storage system; the fuel pump assembly pumps fuel out and pressurizes it for delivery to the engine; the fuel level measuring device monitors the fuel level in real time and transmits the information to the fuel gauge; the venting system balances air pressure and recovers fuel vapor to reduce pollution; the inlet and outlet fuel lines and interfaces ensure a sealed fuel delivery system; auxiliary accessories include mounting brackets, anti-sloshing plates, and drain plugs, which respectively serve to fix the fuel tank, reduce sloshing, and facilitate maintenance and evacuation.

[0003] Existing fuel tank assemblies are susceptible to damage during vehicle operation. When encountering road debris, collisions with obstacles, or bottoming out, the external impact force directly affects the fuel tank. For example, flying debris can easily create dents or even punctures on the tank surface. Furthermore, the fuel tank assembly is typically mounted in the vehicle chassis, lacking sufficient cushioning and buffering structures, making it vulnerable to impacts and prone to damage. Therefore, a new fuel tank assembly design is needed.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] This utility model provides a fuel tank assembly to solve the problem that when the fuel tank assembly is hit by flying gravel, collision, or bottoming out, it is easy to form dents or even small puncture holes on the surface of the fuel tank. Because it is mounted on the chassis and lacks buffering, it is difficult to withstand impact and is easily damaged.

[0006] The present invention adopts the following technical solution: a fuel tank assembly. It mainly includes a fuel tank body with a fixed bracket on it; a buffer assembly disposed on the fixed bracket, the buffer assembly including a protective plate for buffering and protecting the bottom of the fuel tank body; and a protective assembly disposed on the protective plate, the protective assembly including a protective net for protecting the front end of the fuel tank body, and a fixing part for clamping and fixing the protective net on the protective plate.

[0007] Furthermore, the fixing part includes a bottom ring integrally disposed on the protective plate. One end of the bottom ring is connected to a clamping ring by a hinge. The bottom ring and the clamping ring cooperate to form an openable and closable annular frame. Both the bottom ring and the clamping ring are provided with clamping grooves adapted to the protective net. When the bottom ring and the clamping ring are closed, the clamping grooves form a wrapping fixing structure for the protective net.

[0008] Furthermore, an open slot plate is installed on the clamping ring away from the hinge end with the bottom ring, and the slot of the open slot plate is aligned with the end of the bottom ring to be connected. A hinge shaft is movably connected to the bottom ring away from the hinge end with the clamping ring, and a fastener is threaded onto the hinge shaft. The fastener is a wing nut.

[0009] Furthermore, the buffer assembly includes two sets of mounting brackets installed on the fixed bracket. One end of each set of mounting brackets is connected to a support bracket. Buffer rods are slidably arranged at both ends of the support brackets. A groove adapted to the buffer rod is opened at one end of the support bracket. A slider is installed on the side of the buffer rod. A guide rail adapted to the slider is installed on the inner wall of the groove. A damping spring is connected to one end of the buffer rod and the top of the inner wall of the groove.

[0010] Furthermore, the protective plate is connected to one end of the two sets of buffer rods and fixed by fasteners. The protective plate has an arc-shaped structure and is adapted to the bottom contour of the fuel tank body.

[0011] Furthermore, the fuel tank body is provided with a filler cap for sealing the filler neck and ensuring the fuel storage seal, and the fuel tank body is provided with a fuel pump assembly.

[0012] Furthermore, the fuel tank body is provided with a fuel outlet port, which serves as a connection channel for fuel output.

[0013] Furthermore, the fixing bracket uses a connecting structure to wrap and fix the fuel tank body. The connecting structure is adapted to the shape of the fuel tank body and cooperates with the fixing bracket to perform the installation and fixing function.

[0014] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0015] A fuel tank assembly features multi-layered protection formed by mounting a buffer component and a protective component on a fixed bracket outside the fuel tank body. The protective plate adapts to the bottom contour of the fuel tank and can first withstand impacts such as road debris splashing and bottoming out. In conjunction with a buffer rod, damping spring, and guide rail slider, the impact force can be converted into mechanical energy from the sliding of the buffer rod and the compression of the spring. The energy is dissipated by the damping medium, attenuating vertical and lateral impact forces and preventing direct damage to the bottom. The protective net of the protective component is clamped by a fixed part to intercept front-end splashes and scraping impacts. The high-strength material and clamping structure of the protective net allow it to stably seal when impacted. With the help of a hinge shaft, an open slot plate, and fasteners, it can be easily disassembled and reliably locked. Attached Figure Description

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1-5 As shown, this utility model embodiment provides a fuel tank assembly, including a fuel tank body 11 for storing fuel, and a fuel filler cap 12 for sealing the filler neck and ensuring the fuel storage is airtight. A fuel pump assembly 13 is also provided on the fuel tank body 11, which can draw fuel from the fuel tank and deliver it to the engine to provide power supply. At the same time, a fuel outlet pipe interface 14 is provided on the fuel tank body 11, which serves as a connection channel for fuel output and is used to connect to the fuel delivery pipe.

[0028] In order to achieve a stable installation of the fuel tank assembly 1 on the vehicle, a fixing bracket 15 is provided on the fuel tank body 11, and the fixing bracket 15 is fixed to the fuel tank body 11 by a connecting structure 16. The connecting structure 16 fits the shape of the fuel tank body 11 and cooperates with the fixing bracket 15 to play a reliable installation and fixing role, so that the entire fuel tank assembly 1 can be adapted to be installed in the designated position of the vehicle, ensuring the stable realization of the vehicle's fuel storage and supply functions.

[0029] To protect the bottom of the fuel tank body 11 during use, such as Figures 3-5 As shown, a buffer assembly 2 is installed on the fixed bracket 15. The buffer assembly 2 includes two sets of mounting brackets 21 fixedly mounted on the fixed bracket 15, and a support bracket 22 is connected to one end of the two sets of mounting brackets 21. Buffer rods 23 are slidably arranged at both ends of the support bracket 22. At the same time, a sliding groove (not shown in the figure) adapted to the buffer rod 23 is opened at one end of the support bracket 22. A slider 231 is fixedly installed on the side of the buffer rod 23. At the same time, a guide rail 221 adapted to the slider 231 for sliding is fixedly installed on the inner wall of the sliding groove. At the same time, a damping spring (not shown in the figure) is connected to one end of the buffer rod 23 and the top of the inner wall of the sliding groove. With the help of the guide rail 221, the slider 231 and the damping spring, the buffer rod 23 can play a buffering and energy absorption role when it slides.

[0030] It should be noted that the internal damping structure of the damping spring can consume the energy of the spring's reciprocating motion through the viscous resistance of the damping medium (such as silicone oil) during the spring's compression and rebound process. Compared with ordinary springs, it can effectively suppress the repeated high-frequency up and down sliding of the spring caused by impact, making the buffering process smoother.

[0031] Furthermore, an arc-shaped protective plate 24 is installed at one end of each of the two sets of buffer bars 23 via fasteners 36. This protective plate 24 can adapt to the bottom contour of the fuel tank body 11. When the fuel tank encounters road impacts, bottoming out, or other situations, the external force acts on the protective plate 24. Through the cooperation of the buffer bars 23, damping springs, and other components, the impact force is effectively attenuated, preventing damage to the bottom of the fuel tank body 11 and improving the impact protection performance of the fuel tank assembly 1.

[0032] Meanwhile, a protective component 3 for protecting the front end of the fuel tank body 11 is provided at one end of the protective plate 24. The protective component 3 includes a fixing part provided on the protective plate 24. The fixing part includes a bottom ring 31 integrated on the protective plate 24. The bottom ring 31 serves as a basic support structure. One end of the bottom ring 31 is connected to a clamping ring 32 by a hinge. The two work together to form an openable ring frame to adapt to the front contour of the fuel tank body 11. To enhance the protection effect on the front area, a protective net 33 is provided between the bottom ring 31 and the clamping ring 32.

[0033] The protective net 33 is made of high-strength and tough mesh material, which can effectively intercept the impact of gravel, scratches and other damage. In order to achieve a stable installation of the protective net 33, the bottom ring 31 and the clamping ring 32 are provided with clamping grooves that are compatible with the protective net 33 (not shown in the figure). When the bottom ring 31 and the clamping ring 32 are closed, the clamping grooves will form a wrapping and fixing structure for the protective net 33, clamping the protective net 33 from the top and bottom, ensuring that the protective net 33 is not easy to fall off or shift when impacted, and continues to play a protective role, forming a protective barrier at the front end of the fuel tank body 11.

[0034] An open slotted plate 34 is fixedly installed on the clamping ring 32 away from the hinged end with the bottom ring 31, and the slot opening is oriented to facilitate mating and connection with the corresponding end of the bottom ring 31. At the same time, a hinge shaft 35 is movably connected to the bottom ring 31 away from the hinged end with the clamping ring 32. The hinge shaft 35 can rotate around its own axis. When it is necessary to close the bottom ring 31 and the clamping ring 32, the hinge shaft 35 is rotated to engage with the slot in the open slotted plate 34, thus initially achieving the connection and fixation between the bottom ring 31 and the clamping ring 32.

[0035] To further strengthen the connection and prevent the clamping ring 32 from loosening due to vehicle vibration, a fastener 36 is threaded onto the hinge shaft 35. The fastener 36 can be a structure that is easy to operate manually, such as a wing nut. After tightening the fastener 36, the connection between the hinge shaft 35 and the open slot plate 34 can be tightly locked, so that the bottom ring 31 and the clamping ring 32 can remain in a closed clamping state. This ensures the reliability of the overall protection of the front end of the fuel tank body 11 by the protective assembly 3, and stably performs the protection function of the front end area. Together with the protective plate 24, it forms a multi-directional protection structure for the fuel tank assembly 1.

[0036] Working principle: During daily use, fuel is stored inside the fuel tank body 11, and the filler cap 12 seals the filler neck to ensure airtightness. When the vehicle encounters impacts such as flying gravel or bottoming out, the protective plate 24 absorbs the impact from the road surface, disperses stress through the arc structure, and then transmits it to the damping spring through the buffer rod 23. The spring compression and the damping medium absorb energy, attenuating the vertical / lateral impact force and preventing direct damage to the fuel tank body 11. At the same time, the protective component 3 targets the weak front area (such as pipelines and sensors), and uses the bottom ring 31 and clamping ring 32 to close and clamp the protective net 33 to intercept splashes and scrape impacts, forming a double layer of protection with bottom buffering and front interception. The fixed bracket 15 and connecting structure 16 ensure the stability of the main body installation, allowing each protective component 3 to work together to resist external impacts from different directions and forms.

[0037] In bottoming-out collisions and scrapes in complex road conditions, when bottoming out, the protective plate 24 is squeezed by the ground protrusion, the buffer rod 23 slides along the groove of the support frame 22, the damping spring is quickly compressed to absorb energy, and the guide rail 221 and the slider 231 cooperate to ensure the stability of the buffer direction and avoid concentrated impact force to damage the bottom of the body; when scraping the side, the protective net 33 of the protective component 3 first intercepts gravel and obstacles. If the impact force is transmitted to the clamping ring 32, the locking structure of the hinge shaft 35 and the opening slot plate 34 plus the fastener 36 locks it to ensure that the clamping ring 32 does not loosen, and the protective net 33 continues to block the front end; during maintenance, the protective component 3 can be quickly opened and closed by rotating the hinge shaft 35 and removing the fastener 36, taking into account both protection and ease of operation. Centered on the fuel tank body 11, each component forms a closed-loop protection system encompassing storage, sealing, impact energy absorption, and scrape interception, providing active buffering, passive interception, and convenient maintenance. This ensures that the fuel tank assembly 1 can stably supply fuel under different operating conditions and resist damage through the coordinated action of multiple components, thereby guaranteeing the safety of the vehicle's fuel system.
