Description

Technical Field

[0001] This utility model relates to the field of automotive fuel tank technology, specifically to an automotive fuel tank with a protective outer cover structure. Background Technology

[0002] The fuel tank is a crucial component of a vehicle's fuel system. Its primary function is to store fuel, which is essential for the normal operation of the engine. Currently, the fuel tanks of large trucks and trailers are typically fixed to one side of the chassis, directly exposed to the external environment. In the event of a traffic accident, external objects can directly impact the fuel tank. Therefore, protective covers are now installed around the fuel tank to protect it from damage and prevent safety hazards such as gasoline leaks.

[0003] For protective covers fixed to the outside of fuel tanks, the protective cover needs to be fixedly connected to the vehicle frame using components such as mounting supports and screws. However, when inspecting the surface of the fuel tank for corrosion or checking for leaks at fuel line connections, it is necessary to first disassemble the protective cover from the vehicle frame and then remove it from the outside of the fuel tank. Furthermore, the space available for the installation location of the fuel tank varies for different vehicle models, and the mounting supports that are fixed to the protective cover cannot meet the installation requirements, increasing the workload and difficulty for workers. To address the shortcomings of existing technologies, we propose a fuel tank with a protective cover structure to solve the above problems. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This application provides a car fuel tank with a protective cover structure, which solves the problem that when inspecting the surface of the fuel tank for corrosion or leakage at fuel pipe connections, it is necessary to first disassemble the protective cover from the car frame and then remove the protective cover from the outside of the fuel tank. Furthermore, different car models have different spaces for the fuel tank installation location, and the mounting supports that are fixed to the protective cover cannot meet the installation requirements, increasing the workload and difficulty for workers. This application achieves convenient opening and closing of the protective cover and convenient adjustment of the position of the mounting supports at the protective cover.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] This utility model discloses an automotive fuel tank with a protective outer cover structure.

[0029] According to the appendix Figure 1-7 As shown, the system includes a car fuel tank body 1, a protective base plate 2 fixedly mounted on the bottom surface of the car fuel tank body 1, and two sets of protective covers 21 combined and mounted on the outside of the car fuel tank body 1. The protective covers 21 can be made of high-strength metal materials, such as aluminum alloy and stainless steel, which have good impact resistance and corrosion resistance; or they can be made of engineering plastics and other polymer materials, which are lightweight and low-cost, while possessing a certain degree of toughness and corrosion resistance. Furthermore, an epoxy resin layer can be fixedly connected to the outer wall of the protective covers 21. Epoxy resin has good corrosion resistance and can effectively isolate corrosive substances from the protective covers and the fuel tank body. The inner walls of the two sets of protective covers 21 are fixedly connected with sliders 23 for limiting the connection between the protective covers 21 and the protective base plate 2. A locking screw 22 is rotatably provided between the two sets of protective covers 21 for locking them together. See the attached diagram for details. Figure 2-3 When the locking screw 22 is unlocked, the two sets of protective covers 21 are in a movable connection state. At this time, with the assistance of the slider 23, the two sets of protective covers 21 can slide to both sides along the protective base plate 2, so that the car fuel tank body 1 located inside the two sets of protective covers 21 is exposed, so as to inspect the car fuel tank body 1.

[0030] See attached document Figure 2-4 Both sets of protective covers 21 have a first reinforcing rib 4 fixedly connected to their outer walls, and both sets of protective covers 21 have heat dissipation fins 5 fixedly connected to their outer walls. The heat dissipation fins 5 can accelerate the dissipation of heat at both sets of protective covers 21, reduce the accumulation of heat inside the two sets of protective covers 21, and prevent the pressure of the car fuel tank body 1 from rising due to high temperature, thereby preventing the car fuel tank body 1 from rupturing. A locking screw 22 for locking between the two sets of protective covers 21 is rotatably provided. The outer wall of the car fuel tank body 1 is fixedly connected to a second reinforcing rib 6. The first reinforcing rib 4 and the second reinforcing rib 6 increase the impact resistance of the protective covers 21 and the car fuel tank body 1, thereby reducing the damage to the car fuel tank body 1 caused by external impact.

[0031] See attached document Figure 1 Appendix Figure 6 and attached Figure 7The bottom surface of the protective base plate 2 is provided with a displacement mechanism 3. This displacement mechanism 3 allows for adjustments to the installation position of the mounting supports 34 between the fuel tank body 1 and the vehicle, based on factors such as space constraints within the vehicle. The displacement mechanism 3 includes a base 31, with two sets of bases 31 fixedly mounted on the bottom surface of the protective base plate 2. A first screw 32 and a second screw 33 are rotatably mounted inside one set of bases 31. Bolts are threaded to the outer walls of the ends of the first screw 32 and the second screw 33 extending outside the base 31. A set of mounting supports 34 for fixing the fuel tank body 1 to the vehicle surface is threaded to the first screw 32 and the second screw 33, respectively. This allows for adjustments to the position of different mounting supports 34 based on actual conditions. A set of threaded blocks 35, threaded to the outer wall of the first screw 32, is fixedly connected to the top surface of one set of mounting supports 34. A set of blocks 35, slidably connected to the outer wall of the second screw 33, is also fixedly connected to the top surface of the other set of mounting supports 34. One set of limiting blocks 36, and another set of threaded blocks 35 that are threaded to the outer wall of the second screw 33 are fixedly connected to the top surface of the other set of mounting pillars 34. Another set of limiting blocks 36 that are slidably connected to the outer wall of the first screw 32 are fixedly connected to the top surface of the other set of mounting pillars 34. This ensures that the multiple sets of mounting pillars 34 will not affect each other when their positions are changed. Specifically, by rotating the first screw 32 and the second screw 33 in sequence, the positions of the two sets of mounting pillars 34 on the corresponding base 31 can be changed in sequence. This allows the mounted pillars 34 on the protective base plate 2 to be securely installed on the surface of the car mounting position by screws or other threaded parts. The mounting pillars 34 will not obstruct the connection with the surface of the car mounting position. Furthermore, the mounting pillars 34 in this position will not obstruct the opening and closing path of the two sets of protective covers 21. This allows the two sets of protective covers 21 to be opened and closed conveniently without changing the position of the car fuel tank body 1.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
