[0028] As cars become more and more common, people have increasingly higher requirements for their reliability.

[0029] Currently, rainwater and other impurities from outside the vehicle can easily enter and remain between the side panel and the rear wheel arch panel through the fuel filler neck, which can easily lead to damage to the side panel and the rear wheel arch panel. For example, rainwater entering the fuel filler neck and remaining between the side panel and the rear wheel arch panel can easily cause corrosion of the side panel and the rear wheel arch panel.

[0030] This application provides a vehicle, please refer to... Figure 1 , Figure 1 This is a structural schematic diagram of a vehicle according to one or more embodiments of this application.

[0031] Vehicle 1 includes a fuel filler assembly 2. Vehicle 1 can be a new energy vehicle, such as a hybrid vehicle or a range-extended vehicle. Vehicle 1 can be a front-wheel drive vehicle, a four-wheel drive vehicle, etc. The fuel filler assembly 2 has good torsional rigidity and structural strength. It forms a fuel filler port, through which fuel can be added to vehicle 1. For example, vehicle 1 may also include a fuel tank, and the fuel filler assembly 2 can be connected to the fuel tank.

[0032] Combination Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of a filler cap assembly according to one or more embodiments of this application.

[0033] To solve the above problems, this application provides a fuel filler assembly 2, which includes a fuel filler pipe 10, a side panel 20, a rear wheel arch panel 30, and a sealing part 40. The side panel 20 has a fuel filler port 21 that penetrates the opposite two surfaces of the side panel 20 and is connected to the fuel filler pipe 10. The rear wheel arch panel 30 is located on the side of the side panel 20 facing the fuel filler pipe 10, and a side panel cavity 31 is formed between the rear wheel arch panel 30 and the side panel 20. The sealing part 40 is disposed between the side panel 20 and the rear wheel arch panel 30 to separate the side panel cavity 31 from the fuel filler port 21.

[0034] The fuel filler pipe 10 can be used to connect to the fuel tank of vehicle 1, thereby facilitating the replenishment of fuel into the fuel tank through the fuel filler pipe 10. The side panel 20 and the rear wheel arch panel 30 are two important covering parts in the body structure of vehicle 1. The side panel 20 can be used to define the overall side boundary and appearance of the body, and the rear wheel arch panel 30 can be used to provide coverage space for the rear wheels of vehicle 1, accommodating tire movement, etc. The fuel filler port 21 penetrates the opposite surfaces of the side panel 20 and is connected to the fuel filler pipe 10. Fuel can be replenished into the fuel filler pipe 10 through the fuel filler port 21. Specifically, the fuel nozzle can be connected to the fuel filler pipe 10 through the fuel filler port 21 to replenish fuel into the fuel filler pipe 10. When fuel is being replenished into the fuel filler pipe 10 through the fuel nozzle, the side panel 20 can provide support for the fuel nozzle. A side wall cavity 31 is formed between the rear wheel arch outer panel 30 and the side wall outer panel 20. Specifically, a portion of the rear wheel arch outer panel 30 may be spaced apart from the side wall outer panel 20 to form the side wall cavity 31. It is understood that when the corresponding positions of the side wall outer panel 20 and the side wall cavity 31 are subjected to a collision, the side wall cavity 31 helps to absorb the collision energy received by the corresponding positions of the side wall outer panel 20, thereby improving the dent resistance of the side wall outer panel 20. Meanwhile, the sealing part 40 is disposed between the side outer panel 20 and the rear wheel arch outer panel 30, separating the side cavity 31 from the fuel filler neck 21. It is understandable that if rainwater or other impurities may enter the inner side of the side outer panel 20 through the fuel filler neck 21, the sealing part 40 can reduce the risk of rainwater or other impurities entering and remaining in the side cavity 31. It should be noted that, taking rainwater as an example, if rainwater enters the side cavity 31, it is likely to remain inside the side cavity 31, leading to corrosion of the side outer panel 20 and the rear wheel arch outer panel 30. The sealing part 40 can be, but is not limited to, sealant, sealing strip, sealing plug, etc. The sealant can include, but is not limited to, body expansion adhesive, etc. It is understood that separating the side cavity 31 from the fuel filler neck 21 with sealant can effectively mitigate the risk of rainwater or other impurities entering the side cavity 31 through the fuel filler neck 21, while also having a simple structure and low cost.

[0035] Through the above-described embodiments, the rear wheel arch outer plate 30 and the side wall outer plate 20 cooperate to form a side wall cavity 31, thereby enhancing the dent resistance of the side wall outer plate 20. At the same time, the sealing part 40 separates the side wall cavity 31 from the filler port 21, mitigating the risk of rainwater and other impurities entering the side wall cavity 31 through the filler port 21 and causing corrosion of the side wall outer plates 20 and the rear wheel arch outer plate 30 on both sides of the side wall cavity 31, thus improving the reliability of the filler port assembly 2.

[0036] In some embodiments, the fuel filler assembly 2 further includes a cover plate 50 and a seal 60. The cover plate 50 is disposed on the fuel filler 21 and serves to cover the fuel filler 21. The seal 60 is disposed between the cover plate 50 and the outer side panel 20 to provide a seal between the cover plate 50 and the outer side panel 20. The cover plate 50 can be disposed on the fuel filler 21 to cover the fuel filler 21 in a closed state or to expose the fuel filler 21 in an open state. For example, when the vehicle 1 is in the refueling state, the cover plate 50 can be in the open state, thereby exposing the fuel filler 21 to the outside. When the vehicle 1 is not in the refueling state, the cover plate 50 can be in the closed state, thereby covering the fuel filler 21 to isolate the fuel filler 21 from the outside. The cover plate 50 can be disposed on the fuel filler 21 by means including but not limited to flip-top or sliding cover. The seal 60 can be including but not limited to sealing strips, sealing rings, etc. It is understood that by the cooperation of the cover plate 50 and the seal 60 to cover and seal the fuel filler 21, the risk of rainwater and other impurities entering the fuel filler 21 is reduced. It should be noted that the seal 60 is located at the filler neck 21 and is exposed to the external environment for a longer period of time than the sealing part 40. Therefore, the seal 60 has a higher risk of aging and failure than the sealing part 40. Even if the seal 60 fails due to aging, the sealing part 40 can still effectively prevent rainwater and other impurities from entering the side cavity 31, thereby greatly improving the reliability of the filler neck assembly 2 and effectively mitigating the risk of corrosion of the side outer panel 20 and the rear wheel arch outer panel 30.

[0037] In some embodiments, the fuel filler assembly 2 further includes a mounting plate 70 located on the side of the rear wheel arch outer panel 30 away from the side panel 20. The mounting plate 70 has mounting openings 71 extending through opposite surfaces of the mounting plate 70, and the fuel filler pipe 10 is installed in the mounting openings 71. The mounting plate 70 provides mounting space for the fuel filler pipe 10 through the mounting openings 71, and provides support and protection for the fuel filler pipe 10, improving the stability of the fuel filler pipe 10. The fuel filler pipe 10 can be installed in the mounting opening 71 by means including but not limited to snap-fit, screw-fit, welding, etc. Exemplarily, the mounting plate 70 may also have fixing holes located around the mounting opening 71. The fuel filler pipe 10 can be installed in the mounting opening 71 by connecting to a fixing member, with the fixing member inserted into the fixing hole. The fixing member can be, but is not limited to, screws, bolts, and pins. Thus, by providing fixation and support for the fuel filler pipe 10 through the mounting plate 70, the stability of the fuel filler pipe 10 is improved, the risk of relative movement of the fuel filler pipe 10 relative to the fuel filler port 21 is reduced, and the reliability of the fuel filler assembly 2 is improved.

[0038] In some embodiments, the rear wheel arch outer panel 30 includes a first portion 32 and a second portion 33 disposed opposite to each other in the gravity direction x1. The first portion 32 is located upstream of the filler neck 21 in the gravity direction x1, and the second portion 33 is located downstream of the filler neck 21 in the gravity direction x1. The mounting plate 70 is connected to the first portion 32 and spaced apart from the second portion 33. It should be noted that the first portion 32 refers to the portion of the rear wheel arch outer panel 30 located upstream of the filler neck 21 in the gravity direction x1, and the second portion 33 refers to the portion of the rear wheel arch outer panel 30 located downstream of the filler neck 21 in the gravity direction x1. It is understandable that rainwater and other impurities, after entering the filler neck 21, will naturally fall under the influence of gravity, that is, fall towards the location of the second part 33. By connecting the mounting plate 70 to the first part 32 and setting it apart from the second part 33, it is easy to connect the mounting plate 70 to the rear wheel arch outer plate 30. This allows the rear wheel arch outer plate 30 to provide fixation and support for the mounting plate 70 through the first part 32. At the same time, the spacing between the mounting plate 70 and the second part 33 reduces the risk of rainwater and other impurities falling into the groove or other stagnant space formed between the mounting plate 70 and the second part 33. This improves the stability of the mounting plate 70 and effectively mitigates the risk of rust and other damage to the rear wheel arch outer plate 30 and the mounting plate 70 caused by the retention of rainwater and other impurities.

[0039] In some embodiments, at least a partial side cavity 31 is defined between the second part 33 and the outer side panel 20. A first opening 34 is provided between the second part 33 and the outer side panel 20, connecting the side cavity 31 and the filler neck 21. A sealing part 40 is located at least at the first opening 34 to seal it. Since a partial side cavity 31 is formed between the second part 33 and the outer side panel 20, during production and assembly, before the sealing part 40 is provided at the first opening 34, the side cavity 31 and the filler neck 21 can communicate through the first opening 34. By providing the sealing part 40 at the first opening 34, the first opening 34 can be sealed, and the side cavity 31 can be separated from the filler neck 21. It is understood that sealing the first opening 34 with the sealing part 40 can effectively prevent rainwater and other impurities from entering the side cavity 31 between the second part 33 and the outer side panel 20, while also offering a simple structure and low cost.

[0040] In some embodiments, a partial side cavity 31 is defined between the first part 32 and the outer side panel 20. A second opening 35 is provided between the first part 32 and the outer side panel 20, and the second opening 35 connects the side cavity 31 and the filler port 21. A sealing part 40 is also located at the second opening 35 to block the second opening 35. It should be noted that the first opening 34 and the second opening 35 can be two independent openings or two different parts of the same opening. For example, the first part 32 and the second part 33 can independently define a partial side cavity 31. The partial side cavity 31 defined by the first part 32 and the partial side cavity 31 defined by the second part 33 are not connected. The first opening 34 connects the partial side cavity 31 defined by the second part 33 and the filler port 21, and the second opening 35 connects the partial side cavity 31 defined by the first part 32 and the filler port 21. Alternatively, the first part 32 and the second part 33, together with the side outer panel 20, define a completely connected side cavity 31. The rear wheel arch outer panel 30 forms an annular opening in the circumferential direction of the fuel filler 21. The first opening 34 is the portion of the annular opening downstream of the fuel filler 21 in the gravity direction x1, and the second opening 35 is the portion of the annular opening upstream of the fuel filler 21 in the gravity direction x1. During production and assembly, before the sealing part 40 is installed at the second opening 35, the side cavity 31 and the fuel filler 21 can be connected through the second opening 35. By installing the sealing part 40 at the second opening 35, the second opening 35 can be sealed, separating the side cavity 31 from the fuel filler 21. It can be understood that sealing the second opening 35 with the sealing part 40 can effectively prevent rainwater and other impurities from entering the side cavity 31 between the first part 32 and the side outer panel 20, while also having a simple structure and low cost. In the case where the first opening 34 and the second opening 35 are different parts of annular openings, the sealing part 40 can also be arranged in annular shape. For example, the sealing part 40 can be a sealant, and the sealing member 60 can be arranged around the annular opening to separate the side cavity 31 from the oil filler port 21.

[0041] In some embodiments, the orthographic projection of the filler neck 21 onto a reference plane perpendicular to the gravity direction x1 is spaced apart from the orthographic projection of the first opening 34 onto the reference plane. As mentioned earlier, rainwater and other impurities entering the filler neck 21 will fall naturally under the influence of gravity. By spaced apart the orthographic projection of the filler neck 21 onto the reference plane perpendicular to the gravity direction x1 and the orthographic projection of the first opening 34 onto the reference plane, it is beneficial to offset the first opening 34 from the filler neck 21 in the gravity direction x1. This allows the first opening 34 to avoid rainwater and other impurities entering from the filler neck 21 and falling naturally under gravity, further reducing the risk of rainwater and other impurities falling into the side cavity 31. For example, in the horizontal direction perpendicular to the gravity direction x1, the first opening 34 can be further away from the filler pipe 10 than the filler neck 21.

[0042] In some embodiments, the second part 33 has a first guide surface 331 on the side facing the mounting plate 70, and the mounting plate 70 has a second guide surface 72 on the side facing the second part 33. A gap 80 is formed between the first guide surface 331 and the second guide surface 72, connecting the filler neck 21 to the outside. It should be noted that the first guide surface 331 and the second guide surface 72 can be used to receive and guide rainwater and other impurities entering the filler neck 21, and guide the rainwater and other impurities to the gap 80, and then discharge them to the outside through the gap 80. The gap 80 is located downstream of the filler pipe 10 in the gravity direction x1. Understandably, taking rainwater as an example, if rainwater enters the filler neck 21 and comes into contact with the second part 33 of the rear wheel arch outer panel 30, the rainwater will flow along the first guide surface 331 to the gap 80 and be discharged to the outside. If rainwater enters the filler neck 21 and comes into contact with the mounting plate 70, the rainwater will flow along the second guide surface 72 to the gap 80 and be discharged to the outside. Thus, the efficiency of rainwater and other impurities being discharged to the outside can be effectively improved by the first guide surface 331 and the second guide surface 72, reducing the risk of damage to the side panel 20, the rear wheel arch outer panel 30, and the mounting plate 70 caused by the retention of rainwater and other impurities.

[0043] In some embodiments, the distance between the first guide surface 331 and the second guide surface 72 decreases in the direction from upstream to downstream of the gravity direction x1. It should be noted that the decreasing distance between the first guide surface 331 and the second guide surface 72 can mean that the distance between them decreases gradually or in stages. For example, the space between the first guide surface 331 and the second guide surface 72 can be approximately funnel-shaped, meaning that the radial dimension of the funnel-shaped space gradually decreases in the direction from the refueling pipe 10 to the gap 80, or the radial dimension of the funnel shape gradually decreases over a certain distance, remains constant for another distance, and continues to gradually decrease over the next distance. Understandably, the decreasing distance between the first guide surface 331 and the second guide surface 72 helps to reduce the space on the first guide surface 331 and the second guide surface 72 that could cause rainwater and other impurities to accumulate, thereby improving the guiding efficiency and mitigating the risk of damage such as rust on the outer wheel cover and mounting plate 70 caused by rainwater and other impurities.

[0044] In summary, the fuel filler assembly 2 provided in this application includes a fuel filler pipe 10, a side panel 20, a rear wheel arch panel 30, and a sealing part 40. The side panel 20 has a fuel filler port 21 that penetrates the opposite sides of the side panel 20 and is connected to the fuel filler pipe 10. The rear wheel arch panel 30 is located on the side of the side panel 20 facing the fuel filler pipe 10, and a side cavity 31 is formed between the rear wheel arch panel 30 and the side panel 20. The sealing part 40 is disposed between the side panel 20 and the rear wheel arch panel 30 to separate the side cavity 31 from the fuel filler port 21. Through the above-described embodiments, the rear wheel arch outer plate 30 and the side wall outer plate 20 cooperate to form a side wall cavity 31, thereby enhancing the dent resistance of the side wall outer plate 20. At the same time, the sealing part 40 separates the side wall cavity 31 from the filler port 21, mitigating the risk of rainwater and other impurities entering the side wall cavity 31 through the filler port 21 and causing corrosion of the side wall outer plates 20 and the rear wheel arch outer plate 30 on both sides of the side wall cavity 31, thus improving the reliability of the filler port assembly 2.
