[0027] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0028] As described in the background section, existing automotive fuel filler caps are designed to take into account the specific screwing and tightening issues; therefore, a gap needs to be left between the fuel filler cap and the plane where the fuel tank filler neck or cylinder head cover is located (e.g., ...). Figure 5 (As shown at point C) to facilitate tightening the filler cap. The gap between the filler cap and the filler neck of the fuel tank or cylinder head cover easily accumulates dust / sand. When the car is in motion, dust / sand can easily fall onto the filler neck platform end face of the fuel tank or cylinder head cover due to vibration. As the amount of dust / sand accumulated on the filler neck platform end increases, it is easy for dust / sand to enter the interior of the fuel tank or cylinder head cover when the filler cap is opened, thus affecting the service life of the car.

[0029] In view of the above problems, the present invention provides a fuel filler cap and a car that can solve the above problems, which will be described in detail below.

[0030] Please refer to Figure 1 and Figure 2 The filler cap includes a cap body 10, a plug 20 and a gasket 30. The plug 20 is connected to the cap body 10, and the gasket 30 is sleeved on the outside of the plug 20. The gasket 30 is located on the plug 20 near the end of the cap body 10. When the filler cap is closed to the filler port 50 of the fuel tank or cylinder head cover, the gasket 30 covers the filler port 50.

[0031] In this embodiment of the utility model, a gasket 30 is provided between the plug 20 and the cover 10 of the fuel filler cap. The gasket 30 can fill the gap reserved between the fuel filler cap and the fuel filler port 50 of the fuel tank or cylinder head cover. When the fuel filler cap is closed on the fuel filler port 50 of the fuel tank or cylinder head cover, the gasket 30 can fill the gap between the fuel filler cap and the fuel filler port 50 of the fuel tank or cylinder head cover, which can effectively prevent dust / sand from accumulating in the gap. At the same time, the gasket 30 also covers the platform end face of the fuel filler port 50 of the fuel tank or cylinder head cover. Even if a small amount of dust / sand accumulates, it will not fall onto the platform end face of the fuel filler port 50, which can prevent dust / sand from entering the interior of the fuel tank or cylinder head cover, which is beneficial to improving the service life of the car.

[0032] The cover 10 includes an integrally formed cap 101 and a handle 102. The cap 101 is disc-shaped, and the handle 102 is vertically connected to the outer wall of the cap 101. The inner wall of the cap 101 faces the fuel filler port 50 of the fuel tank or cylinder head cover. The handle 102 is set along the diameter of the cap 101 to facilitate easy turning and even force distribution during use. At the same time, the two sides of the handle 102 are recessed to increase the contact area and prevent slippage when gripping.

[0033] The plug 20 is cylindrical in shape, with one end connected to the cap 101 and located at the center of the cap 101. The plug 20 and the cap 101 are concentrically positioned and typically integrally formed. The plug 20 is used to connect with the filler neck 50 of the fuel tank or cylinder head cover to achieve a seal, isolating the interior of the fuel tank or cylinder head cover from the outside. The plug 20 is provided with a spiral groove 202, which spirals along the outer circumference of the plug 20, thereby covering and connecting with the filler neck 50 of the fuel tank or cylinder head cover. The spiral end of the spiral groove 202 is provided with a limiting groove 2021. When screwed into place with the filler neck 50, the protrusion on the filler neck 50 can be locked in the limiting groove 2021. The depth of the limiting groove 2021 is greater than the depth of the spiral groove 202, thereby preventing the filler neck cap from springing back and loosening. It is understood that the outer diameter of the plug 20 is smaller than the outer diameter of the cap 101.

[0034] To achieve a seal between the plug 20 and the filler neck 50, at least one groove 203 is formed on the plug 20. The groove 203 is located above the spiral groove 202 and surrounds the circumference of the plug 20. A sealing ring 2031 is disposed within the groove 203, and the sealing ring 2031 is tightly fitted against the cavity wall of the filler neck 50 to achieve a seal. In this embodiment, only one groove 203 is provided. In other embodiments, there can be multiple grooves 203, which are spaced apart from each other. The sealing ring 2031 can be an O-ring, a U-ring, or other types, as long as the reliability of the seal can be guaranteed.

[0035] It is important to understand that the washer ring 30 positioned between the cap 10 and the plug 20 does not affect the screwing operation of the filler cap, nor does it affect the tightening of the filler cap with the filler port 50 of the fuel tank or cylinder head cover. Optionally, the washer ring 30 is an elastic body, which can elastically contact the platform end face of the filler port 50 when tightened onto it, allowing the filler cap to be screwed into place. Optionally, after the filler cap is fitted onto the filler port 50 of the fuel tank or cylinder head cover, a small gap remains between the washer ring 30 and the platform end face of the filler port 50. For example, in the existing design, the distance between the filler cap and the platform end face of the filler port 50 is 2.2mm. If the thickness of the washer ring 30 is designed to be 2mm, the small gap between the washer ring 30 and the platform end face of the filler port 50 will be 0.2mm. External dust / sand is less likely to enter and accumulate, effectively reducing the probability of dust / sand entering the inside of the fuel tank or cylinder head cover.

[0036] Of course, the thickness of the gasket 30 can be less than the distance between the cap 101 and the filler neck 50, or it can be equal to the distance between the cap 101 and the filler neck 50. In this case, the lower surface of the gasket 30 is attached to the platform end face of the filler neck 50.

[0037] refer to Figure 3 and combined Figure 1 The gasket 30 is a thin circular sheet, with an outer circumference smaller than that of the cap 101 but larger than that of the platform end face of the filler neck 50. To securely fix the gasket to the cap 10 and the plug 20, the upper surface of the gasket 30 can be adhered to the lower surface of the cap 101. Additionally, a locking block 201 can be provided at the junction of the cap 10 and the plug 20. Multiple locking blocks 201 are arranged at equal intervals along the outer circumference of the plug 20. Each locking block 201 is a right-angled trapezoidal plate, with its upper and lower bottom edges respectively connected to the lower surface of the cap 101 and the upper protrusion of the groove 203. Correspondingly, the gasket 30 is provided with multiple slots 301, the same number as the number of locking blocks 201. Each slot 301 corresponds one-to-one with a locking block 201, and the slots 301 and locking blocks 201 are compatible. The locking blocks 201 can be inserted into the slots 301, thereby restricting the rotation of the gasket 30, ensuring the reliability of the gasket 30 connection, and preventing it from falling off. The gasket 30 is an elastomer, and its material can be ethylene propylene diene monomer (EPDM). EPDM has high temperature resistance and solvent resistance, making it suitable for the environment where the fuel filler cap is located.

[0038] refer to Figure 4To further enhance the dust and sand protection of the fuel filler cap, an annular cover 40 can be provided on the cap body 10, located outside the gasket ring 30. Specifically, the annular cover 40 is cylindrical with openings at both ends. The upper end of the annular cover 40 is connected to the lower surface or outer peripheral wall of the cap 101, and the lower end of the annular cover 40 extends to the lower part of the end face of the fuel filler port 50 platform. The height of the annular cover 40 is greater than the distance between the cap body 10 and the fuel filler port 50 of the fuel tank, thereby covering the gap between the fuel filler cap and the fuel tank or cylinder head cover fuel filler port 50, making it difficult for external dust / sand to enter.

[0039] The plug 20 and the gasket 30 are located inside the annular cover 40. The annular cover 40 will not affect the tightening of the filler cap to the filler port 50. By setting the annular cover 40, dust / sand can be initially blocked, reducing the accumulation of dust / sand in the gap between the filler cap and the filler port 50. Combined with the gasket 30, it can effectively block the accumulation of dust / sand.

[0040] The annular cover 40 can be an elastomer so that it can be turned outward during cleaning. When the filler cap is closed at the filler port 50, it can be restored and cover the gap between the filler cap and the filler port 50 and the gasket 30. The material of the annular cover 40 can be antistatic rubber or polymer material.

[0041] This embodiment of the utility model includes a gasket 30 on the fuel filler cap, which fills the gap between the fuel filler cap and the fuel filler port 50 of the fuel tank or cylinder head cover, thereby reducing the accumulation of dust / sand in the gap and decreasing the likelihood of dust / sand falling onto the platform end face of the fuel filler port 50. Furthermore, an annular cover 40 is provided on the fuel filler cap, covering the gap between the fuel filler cap and the fuel filler port 50 of the fuel tank or cylinder head cover, as well as the gasket 30, preventing dust / sand from falling into the gap or the gasket 30. This provides a double dust and sand protection function, effectively preventing dust / sand from entering the fuel tank or cylinder head cover, thus improving the service life of the vehicle.

[0042] The fuel filler cap of this utility model embodiment can be applied not only to the fuel filler port 50 of a car's fuel tank or cylinder head cover, but also to other fuel filler ports 50 that may accumulate dust / sand, and its scope and field of application are not limited.

[0043] An embodiment of this utility model also provides a car including the above-mentioned fuel filler cap. The car uses a fuel filler cap on the fuel tank or cylinder head cover, which can effectively prevent sand and dust from accumulating at the fuel filler cap 50, thus improving the user experience.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
