Description

Technical Field

[0001] This utility model relates to the field of fuel tank technology, specifically to a fuel tank plastic anti-surge plate installation structure. Background Technology

[0002] With the continuous improvement of automobile manufacturing standards, traditional noise sources such as engines, transmission systems, and tires have been well controlled. However, as passengers' demands for ride comfort increase, the noise generated by the vibration of the fuel tank walls due to fuel sloshing during sudden braking significantly affects ride comfort. Therefore, a baffle plate is generally installed inside the fuel tank of automobiles. The baffle plate can effectively reduce the noise generated by the surge of fuel in the tank and improve the overall comfort of the vehicle.

[0003] According to CN220996124U, a plastic baffle assembly structure for a metal fuel tank is disclosed. This technology discloses "an assembly structure for a plastic baffle in a metal fuel tank, comprising: a fuel tank body, a mounting bracket, a plastic baffle, and mounting feet. The mounting bracket is fixed to the fuel tank body, and the mounting feet are integrally injection molded with the plastic baffle. The plastic baffle is fixed within the mounting bracket by the mounting feet. The mounting bracket includes a left limiting hole, a right limiting hole, an upper limiting hole, and a front baffle. The mounting feet include a left limiting block, a right limiting block, an upper limiting block, and a front limiting block. The left limiting block engages with the left limiting hole, the right limiting block engages with the right limiting hole, and the upper limiting block engages with the upper limiting hole. The front limiting block is elastic and contacts the front baffle, pressing the front baffle towards the plastic baffle." This technical solution has the following effects: "It can improve the installation efficiency and quality of the plastic baffle, reduce the manufacturing cost of the metal fuel tank, and enhance product competitiveness."

[0004] In the above solution, the plastic baffle is fixed to the mounting bracket on the fuel tank body by mounting feet; however, since it is a snap-fit ​​connection, its strength is often affected by a variety of factors, such as long-term exposure to fuel fluctuations and impacts, the snap-fit ​​part is prone to deformation, and there may even be insufficient snap-fit, which in turn affects the overall stability and durability. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fuel tank plastic baffle installation structure. After the lower and upper fuel tank shells are installed and fixed, the main component between them can be fixed together through two installation mechanisms. Furthermore, when the lower and upper fuel tank shells are disassembled, the main component can be directly removed from the installation mechanisms without complicated operations. This design not only ensures the stability of the main component during installation but also greatly improves the convenience and efficiency of disassembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fuel tank plastic anti-sloshing plate installation structure, comprising a lower fuel tank shell and an upper fuel tank shell, wherein anti-sloshing plates are installed in the lower and upper fuel tank shells to reduce noise and vibration generated during fuel sloshing, and the anti-sloshing plates include:

[0007] The mounting mechanism includes mounting brackets installed inside both the lower and upper oil tank housings, which are symmetrical to each other, and protrusions fixed inside the mounting brackets.

[0008] The main component includes a baffle installed between two mounting brackets, and several drainage holes opened inside the baffle;

[0009] The fixing mechanism is installed in the lower and upper oil tank housings and is used to fix the mounting mechanism.

[0010] Preferably, the mounting mechanism further includes slots fixed at both ends of the middle part of the mounting frame, and a reinforcing frame installed between the slots on the same side of the two mounting frames.

[0011] Preferably, the fixing mechanism includes a mounting base that is welded and fixed to the inner walls of both ends of the lower oil tank shell and the inner walls of both ends of the upper oil tank shell, and a plurality of threaded holes are opened on the mounting base.

[0012] Preferably, the mounting mechanism further includes mounting grooves formed on the outer walls of both ends of the mounting frame and cooperating with the mounting base, and mounting holes formed inside the mounting grooves.

[0013] Preferably, the main component further includes a frame fixed to the outer ring of the baffle, and reinforcing ribs fixed on both sides of the baffle and fixed inside the frame.

[0014] Preferably, the main component further includes grooves formed at the upper and lower ends of the frame, and the grooves cooperate with the protrusions. Beneficial effects

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a fuel tank plastic anti-sloshing plate installation structure, including a lower fuel tank shell 1 and an upper fuel tank shell 2, wherein an anti-sloshing plate 3 is installed in the lower fuel tank shell 1 and the upper fuel tank shell 2 to reduce noise and vibration generated when fuel sloshing occurs, and the anti-sloshing plate 3 includes:

[0025] The mounting mechanism 31 includes mounting brackets 311 installed inside both the lower oil tank shell 1 and the upper oil tank shell 2, which are symmetrical to each other, and a protrusion 312 fixed inside the mounting bracket 311.

[0026] The main component 32 includes a baffle 322 installed between two mounting brackets 311, and a plurality of drainage holes 323 opened inside the baffle 322;

[0027] The fixing mechanism 33 is installed in the lower oil tank shell 1 and the upper oil tank shell 2 and is used to fix the mounting mechanism 31.

[0028] In this embodiment, after the mounting mechanism 31 is fixed inside both the lower fuel tank 1 and the upper fuel tank 2 by the fixing mechanism 33, the main component 32 between the lower fuel tank 1 and the upper fuel tank 2 can be fixed together by the two mounting mechanisms 31 after they are installed and fixed. When the lower fuel tank 1 and the upper fuel tank 2 are disassembled, the main component 32 can also be directly removed from the mounting mechanism 31 without complicated operations. This design not only ensures the stability of the main component 32 during the installation process, but also greatly improves the convenience and efficiency of disassembly.

[0029] Specifically, the mounting mechanism 31 also includes slots 315 fixed at both ends of the middle part of the mounting bracket 311, and a reinforcing bracket 316 installed between the slots 315 on the same side of the two mounting brackets 311.

[0030] In this embodiment, when the upper and lower mounting brackets 311 are fixed to the main component 32 between them, the reinforcing bracket 316 between them can be fixed through the slot 315, which can increase the overall rigidity of the wave deflector 3 and prevent it from deforming or being damaged when subjected to external forces.

[0031] Specifically, the fixing mechanism 33 includes a mounting base 331 that is welded and fixed to the inner walls of both ends of the lower oil tank shell 1 and the inner walls of both ends of the upper oil tank shell 2, and a plurality of threaded holes 332 are opened on the mounting base 331.

[0032] In this embodiment, the main body component 32 can be installed on any threaded hole 332 on the mounting base 331 via the mounting mechanism 31, and one or more can be installed, thereby improving the applicability of the wave deflector 3.

[0033] Specifically, the mounting mechanism 31 also includes mounting grooves 313 formed on the outer walls of both ends of the mounting bracket 311 and cooperating with the mounting base 331, and mounting holes 314 formed inside the mounting grooves 313.

[0034] In this embodiment, the mounting bracket 311 can be installed between the mounting seats 331 on both sides through the mounting holes 314 and screws.

[0035] Specifically, the main component 32 also includes a frame 321 fixed to the outer ring of the baffle 322, and reinforcing ribs 325 fixed on both sides of the baffle 322 and fixed inside the frame 321.

[0036] In this embodiment, the thickened frame 321 can be more easily installed into the mounting bracket 311 and provides a more reliable support point; the reinforcing rib 325 can disperse the stress that was originally concentrated in a certain area of ​​the baffle 322 to a larger area, thereby reducing the local stress level and preventing the structure from being damaged due to stress concentration.

[0037] Specifically, the main component 32 also includes grooves 324 formed at the upper and lower ends of the frame 321, and the grooves 324 cooperate with the protrusions 312.

[0038] In this embodiment, when the main component 32 is installed between the upper and lower mounting mechanisms 31, the protrusion 312 is embedded in the groove 324, thereby limiting the position of the main component 32 and preventing positional displacement.

[0039] The working principle and usage process of this utility model are as follows: First, the mounting bracket 311 can be installed between the mounting seats 331 on both sides through the mounting holes 314 and screws. The mounting mechanism 31 is fixed inside the lower oil tank shell 1 and the upper oil tank shell 2 through the fixing mechanism 33.

[0040] Then, after the lower oil tank shell 1 and the upper oil tank shell 2 are installed and fixed, the main body component 32 between them can be fixed together by two mounting mechanisms 31; at the same time, the reinforcing frame 316 between them can be fixed by the slot 315, so as to increase the overall rigidity of the wave deflector 3 and prevent it from deforming or being damaged when subjected to external forces.

[0041] When the upper fuel tank shell 1 and the lower fuel tank shell 2 are disassembled, the main component 32 can also be directly removed from the mounting mechanism 31 without complicated operations. This design not only ensures the stability of the main component 32 during installation, but also greatly improves the convenience and efficiency of disassembly.
