Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a fuel filler port installation structure and a vehicle. Background Technology

[0002] The refueling structure is an important part of a vehicle. Typically, the refueling structure is a box-type refueling structure, which includes a refueling port box and a refueling pipe. The refueling port box is recessed, with its upper edge connected to the outer side panel of the vehicle, and the bottom of the refueling port box connected to the refueling pipe.

[0003] In related technologies, the flange portion of the refueling pipe mounting surface is fixed to the wheel cover. In the dry area between the wheel cover and the side outer panel, there is a risk of water leakage due to the matching and installation accuracy of the refueling valve. Therefore, how to reduce the risk of water leakage is a technical problem that urgently needs to be solved. Utility Model Content

[0004] This application provides a fuel filler cap installation structure and a vehicle, which reduces the risk of water leakage inside the vehicle.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, embodiments of this application provide a fuel filler port mounting structure, including an inner wheel cover, a rear wheel cover outer plate, and a mounting bracket; the rear wheel cover outer plate is disposed outside the inner wheel cover, and the rear wheel cover outer plate and the inner wheel cover are at least partially spaced apart to form a wet area; the mounting bracket is located in the wet area and fixed to the rear wheel cover outer plate; wherein, the rear wheel cover outer plate is provided with a fuel filler port, and the fuel filler port mounting structure also includes a fuel filler pipe, the fuel filler pipe is fixed to the mounting bracket, and the end of the fuel filler pipe is fitted to the fuel filler port.

[0007] According to the fuel filler neck installation structure proposed in the first aspect of this application, both the mounting bracket and the fuel filler neck are located in the wet area. Even if a small amount of water accidentally seeps into the vicinity of the fuel filler neck, it will directly enter the wet area instead of remaining inside the vehicle body, reducing the risk of water leakage. On the other hand, the fuel filler neck is fixed to the outer panel of the rear wheel arch by the mounting bracket. The structural strength of the outer panel of the rear wheel arch provides stable support for the fuel filler neck, preventing the neck from shifting due to vehicle vibration and bumps, and improving the installation accuracy of the fuel filler neck and fuel filler neck. At the same time, the mounting bracket can provide stable load support for the fuel filler neck. Bumps and vibrations generated during vehicle driving, as well as fluid impacts in the neck during fuel filling, will generate dynamic loads on the neck. The mounting bracket can offset these loads through its own structural rigidity, preventing the neck from shaking, deforming, or even falling off, and maintaining the structural stability of the neck during long-term service.

[0008] Optionally, the rear wheel cover outer panel includes a top wall and a side wall, the side wall being spaced apart from the inner wheel cover in the left-right direction, and the top wall being disposed on the upper side of the side wall and fixed to the inner wheel cover.

[0009] In the above solution, the side wall can be spaced from the inner wheel cover in the left and right direction, which can accurately reserve the lateral space required for the wet area. This provides sufficient installation and accommodation space for the mounting brackets and refueling lines in the wet area, avoiding assembly interference caused by the crowded layout of components. It also provides operating space for disassembling and assembling lines and adjusting brackets during subsequent maintenance, ensuring that the layout of the entire refueling system components is reasonable and easy to operate. On the other hand, the top wall can work together with the side wall and inner wheel cover to form a complete boundary of the wet area, forming a physical barrier to achieve the closed separation of the wet area and the dry area inside the vehicle, reducing the chance of water leakage.

[0010] Optionally, the mounting bracket includes a first fixing part, a recessed part, and a second fixing part connected in sequence. The recessed part is used to fix the refueling pipeline and is recessed towards the inner wheel cover. The first fixing part is fixed to the top wall, and the second fixing part is fixed to the side wall.

[0011] In the above solution, the recessed part can form a receiving space with the rear wheel arch outer plate, which is convenient for installing other components such as the fuel filler door. The fixing method of fixing the first fixing part and the second fixing part to the top wall and the side wall respectively allows the mounting bracket to form a multi-directional connection with the rear wheel arch outer plate. This can greatly disperse the load borne by the bracket, reduce the impact of pipeline weight and vehicle vibration on the fuel filler pipeline, improve installation reliability, and prevent the bracket from bending or loosening due to concentrated stress. At the same time, this connection method can also allow the mounting bracket, the top wall, and the side wall to jointly strengthen the local structural rigidity of the rear wheel arch outer plate, which helps to ensure the stability of the fit between the fuel filler pipeline and the fuel filler port.

[0012] Optionally, at least one of the first fixing part, the recessed part, and the second fixing part has a reinforcing rib.

[0013] In the above scheme, the reinforcing ribs can specifically enhance the deformation resistance of the corresponding parts. The first fixing part is connected to the top wall and the second fixing part is connected to the side wall. Both of them need to bear the weight and vibration load of the bracket and the refueling pipeline. The reinforcing ribs can prevent the fixing part from bending or breaking due to concentrated force, and ensure the reliability of the fixing to the top wall and side wall. The recessed part is used to fix the refueling pipeline and is in a concave shape. Its structure is prone to collapse due to pipeline compression or vibration. The reinforcing ribs can improve the support rigidity of the recessed part, prevent it from being unable to stably clamp the pipeline after deformation, and ensure that the pipeline installation posture does not deviate.

[0014] Optionally, the fuel filler mounting structure also includes a side panel, which is disposed on the outside of the rear wheel arch panel, and at least a portion of the side wall is fixed to the side panel.

[0015] In the above solution, the outer side panel, as an important load-bearing structure on the outside of the vehicle body, can work together with the side wall to provide support and greatly improve the resistance to deformation. The side wall needs to maintain the distance from the inner wheel cover to ensure the wet area space, and also needs to fix the second fixing part of the mounting bracket. The reinforcement of the outer side panel can prevent the side wall from bending or shifting due to bearing the weight of the bracket, refueling line or vehicle vibration load, ensuring the stability of the lateral space in the wet area, and at the same time providing a more stable fixing base for the mounting bracket, preventing the bracket from becoming loose due to the deformation of the side wall.

[0016] Optionally, the side panel includes a first panel and a second panel, at least a portion of the first panel is fixed to the side wall, the second panel is disposed above the first panel, and at least a portion of the second panel is spaced apart from the inner wheel cover to form a dry area.

[0017] In the above solution, the second plate forms a dry area on the upper side, separated from the inner wheel arch, and forms two independent areas with the wet area on the inner side of the rear wheel arch outer plate. This ensures that the refueling line and mounting bracket are separated from other interior components in the dry area, reducing the chance of leakage. With this design, even if a small amount of water remains in the wet area, the water can be confined within the wet area, preventing water from crossing the area and contacting interior components in the dry area. This reduces the possibility of water intruding into critical areas of the vehicle, achieving regional isolation between the refueling line and other interior components, cutting off the leakage path, and ultimately reducing the chance of leakage. It also avoids the risk that water may indirectly seep into the vehicle through contact with components due to the proximity of the refueling line and bracket to components in the dry area.

[0018] Optionally, the fuel filler port installation structure also includes a fuel filler door, which is located on the outer panel of the rear wheel arch or the outer panel of the side wall. The fuel filler door can selectively open or close the fuel filler port.

[0019] In the above solution, the small door can directly block the fuel filler neck when closed, preventing external impurities such as rainwater, dust, and mud from entering the fuel filler neck during vehicle operation. This prevents impurities from clogging the fuel filler line or affecting fuel cleanliness. It also reduces structural damage caused by foreign objects colliding with the fuel filler neck and protects the mating parts between the fuel filler neck and the fuel filler line.

[0020] Optionally, a sealing layer is provided between the outer side panel and the outer rear wheel arch panel, and the sealing layer surrounds the filler neck.

[0021] In the above solution, the sealant layer can precisely fill the tiny gaps formed between the side panel and the rear wheel arch panel during assembly, preventing rainwater and car wash water from seeping into the gaps between the side panel and the rear wheel arch panel while the vehicle is in motion. It also directly blocks the path of water seepage around the fuel filler neck, preventing water from entering the dry area and causing leakage, further reducing the risk of leakage. At the same time, it can also prevent dust, mud and other impurities from accumulating near the fuel filler neck through the gaps, protecting the mating parts of the fuel filler neck and fuel line from being affected by impurities.

[0022] Optionally, the refueling pipeline includes a flange and a pipe body. The flange is fitted onto the pipe body and fixed to a mounting bracket. The mounting bracket has a mounting hole, the pipe body passes through the mounting hole, and the end of the pipe body is fitted to the refueling port.

[0023] In the above scheme, after the flange is fitted onto the pipe body, it is fixed to the mounting bracket. The surface contact of the flange replaces the single line contact fixation of the pipe body, which can significantly distribute the weight and vibration load borne by the pipe body, and avoid the pipe body from loosening or deformation due to local stress concentration. At the same time, the rigid connection between the flange and the mounting bracket can limit the radial sway of the pipe body, ensuring that the pipe body always maintains the preset installation posture, which helps to improve the installation accuracy of the refueling pipeline. The mounting holes of the mounting bracket form a through-positioning for the pipe body, which can accurately limit the axial direction and spatial position of the pipe body, prevent the pipe body from shifting due to vehicle bumps, and thus ensure the fitting accuracy between the end of the pipe body and the refueling port, and reduce positional deviation.

[0024] Secondly, embodiments of this application provide a vehicle including the fuel filler port mounting structure described in any of the embodiments.

[0025] The vehicle proposed according to the second aspect of this application can significantly reduce the risk of water leakage and impurity intrusion during vehicle operation, avoid damage to electrical components and interior trim due to water leakage, reduce refueling problems caused by loose or misaligned refueling lines, ensure long-term stable operation of the vehicle's fuel supply system, and improve overall vehicle reliability.

[0045] The refueling structure is an important part of a vehicle. Typically, the refueling structure is a box-type refueling structure, which includes a refueling port box and a refueling pipe. The refueling port box is recessed, with its upper edge connected to the outer side panel of the vehicle, and the bottom of the refueling port box connected to the refueling pipe.

[0046] In related technologies, the flange portion of the refueling pipe mounting surface is fixed to the wheel cover. In the dry area between the wheel cover and the side outer panel, there is a risk of water leakage due to the matching and installation accuracy of the refueling valve. Therefore, how to reduce the risk of water leakage is a technical problem that urgently needs to be solved.

[0047] Therefore, to reduce the risk of water leakage inside the vehicle, this application proposes a fuel filler cap mounting structure. The mounting bracket 300 is located in the wet area 700 and fixed to the rear wheel arch outer panel 200. The rear wheel arch outer panel 200 is provided with a fuel filler cap 210. The fuel filler cap mounting structure also includes a fuel filler pipe 400, which is fixed to the mounting bracket 300, and its end engages with the fuel filler cap 210. With this configuration, both the mounting bracket 300 and the fuel filler pipe 400 are located in the wet area 700. Even if a small amount of water (such as car wash water or rainwater) accidentally seeps into the vicinity of the fuel filler cap 210, it will directly enter the wet area 700 instead of remaining inside the vehicle body, thus reducing the risk of water leakage. On the other hand, the refueling line 400 is fixed to the rear wheel arch outer plate 200 by the mounting bracket 300. The structural strength of the rear wheel arch outer plate 200 can provide stable support for the refueling line 400, preventing the line from shifting due to vehicle vibration and bumps. This improves the installation accuracy of the refueling line 400 and the refueling port 210. At the same time, the mounting bracket 300 can provide stable load support for the refueling line 400. Bumps and vibrations generated during vehicle driving, as well as fluid impacts in the line during fuel refueling, will generate dynamic loads on the line. The mounting bracket 300 can offset these loads through its own structural rigidity, preventing the line from shaking, deforming, or even falling off, and maintaining the structural stability of the line during long-term service.

[0048] The following is based on the appendix Figure 1 -Appendix Figure 3 This application describes the refueling port installation structure proposed in its embodiments.

[0049] The fuel filler installation structure according to the first aspect of the present application includes an inner wheel cover 100, a rear wheel cover outer plate 200, and a mounting bracket 300.

[0050] The rear wheel arch outer panel 200 is disposed on the outside of the inner wheel arch 100, and the rear wheel arch outer panel 200 and the inner wheel arch 100 are at least partially spaced apart to form a wet area 700. It can be understood that the inner wheel arch 100 can serve as an inner protective structure close to the wheel, and the rear wheel arch outer panel 200 can serve as an outer body cover. The wet area 700 formed by the two can receive and contain water that accidentally seeps in and drain this water to the outside, preventing water from directly contacting the interior cabin or critical components of the vehicle body, and protecting the electrical components, interior trim and other components inside the vehicle body.

[0051] In other words, the wet zone 700 formed by the gap between the outer rear wheel cover 200 and the inner wheel cover 100 can guide water to flow along the internal path of the wet zone 700 to the rear wheel area for discharge, rather than lingering inside the vehicle body.

[0052] Mounting bracket 300 is located in the wet zone 700 and fixed to the rear wheel arch outer plate 200. It is understood that mounting bracket 300 can provide an additional mounting and fixing position in the wet zone 700. As a rigid structural component of the vehicle body, the rear wheel arch outer plate 200 can provide a stable mounting base for mounting bracket 300. Compared with the inner wheel arch 100, which needs to withstand the impact of wheel vibration, the rear wheel arch outer plate 200 has higher structural strength and less deformation, which can ensure that the mounting bracket 300 is accurately positioned and not easily loosened after installation. This provides a reliable reference for the subsequent fixing of the refueling line 400 and avoids affecting the fitting accuracy between the refueling line 400 and the refueling port 210 due to the displacement of mounting bracket 300.

[0053] The rear wheel arch outer panel 200 is equipped with a filler neck 210. The filler neck mounting structure also includes a filler hose 400, which is fixed to the mounting bracket 300. The end of the filler hose 400 is fitted into the filler neck 210. It is understood that the rear wheel arch outer panel 200, as an external fixing structure of the vehicle body, ensures the structural stability of the filler hose 400 after installation, reducing the risk of the filler neck 210 shifting due to vehicle body deformation.

[0054] Secondly, the refueling line 400 is fixed by the mounting bracket 300, which can ensure the precise routing of the line and prevent disorderly shaking of the line due to vehicle vibration and bumps. Finally, the mounting bracket 300 can improve the matching accuracy between the refueling line 400 and the refueling port 210. Under the constraint of the mounting bracket 300, the refueling line 400 can maintain the stability of its fit with the refueling port 210, further reducing the risk of water leakage caused by loose connection.

[0055] In other embodiments, please refer to Figure 2 and Figure 3 The rear wheel arch outer panel 200 includes a top wall 220 and a side wall 230. The side wall 230 is spaced apart from the inner wheel arch 100 along the left-right direction. The top wall 220 is located above the side wall 230 and is fixed to the inner wheel arch 100. It is understood that the two ends of the top wall 220 along the left-right direction are connected to the side wall 230 and the inner wheel arch 100 respectively. The edge of the top wall 220 can be welded or bolted to the inner wheel arch 100. This application does not limit this.

[0056] In the above scheme, the side wall 230 can be spaced from the inner wheel cover 100 in the left and right directions, which can accurately reserve the lateral space required by the wet zone 700. This provides sufficient installation and accommodation space for the mounting bracket 300 and refueling pipeline 400 in the wet zone 700, avoiding assembly interference caused by the crowded layout of components. It also provides operating space for disassembling and assembling pipelines and adjusting brackets during subsequent maintenance, ensuring that the layout of the entire refueling system components is reasonable and easy to operate.

[0057] On the other hand, the top wall 220, together with the side wall 230 and the inner wheel cover 100, can form a complete boundary of the wet area 700, forming a physical barrier to achieve the closed separation between the wet area 700 and the dry area 800 inside the vehicle, reducing the chance of water leakage.

[0058] In addition, it can significantly improve the overall structural rigidity of the rear wheel arch outer plate 200 and the inner wheel arch 100. Dynamic loads such as bumps and steering generated during vehicle operation can be transmitted and distributed to the inner wheel arch 100 through the top wall 220, effectively preventing the side wall 230 from bending or shifting due to concentrated force, ensuring that the gap between the side wall 230 and the inner wheel arch 100 remains stable, thereby providing a stable installation base for the mounting bracket 300, preventing the bracket from shifting due to deformation of the side wall 230, and ultimately ensuring the positioning accuracy of the refueling pipe 400 and maintaining the stable fit between the refueling pipe 400 and the refueling port 210.

[0059] In other embodiments, please refer to Figure 2 and Figure 3 The mounting bracket 300 includes a first fixing part 310, a recessed part 320 and a second fixing part 330 connected in sequence. The recessed part 320 is used to fix the refueling pipe 400 and is recessed towards the inner wheel cover 100. It can be understood that the recessed part 320 can form a receiving space with the outer plate 200 of the rear wheel cover, which is convenient for installing other components such as the refueling gate 600.

[0060] The first fixing part 310 is fixed to the top wall 220, and the second fixing part 330 is fixed to the side wall 230. It can be understood that the fixing method in which the first fixing part 310 and the second fixing part 330 are fixed to the top wall 220 and the side wall 230 respectively allows the mounting bracket 300 to form a multi-directional connection with the rear wheel arch outer plate 200, which can significantly distribute the load borne by the bracket, reduce the impact of pipeline weight and vehicle vibration impact on the refueling pipeline 400, improve installation reliability, and prevent the bracket from bending or loosening due to concentrated stress.

[0061] At the same time, this connection method also allows the mounting bracket 300, together with the top wall 220 and the side wall 230, to strengthen the local structural rigidity of the rear wheel arch outer plate 200, further consolidate the boundary of the wet zone 700, prevent the separation between the dry zone 800 and the wet zone 700 due to bracket deformation, and ultimately ensure the stability of the fit between the refueling pipeline 400 and the refueling port 210.

[0062] In other embodiments, at least one of the first fixing part 310, the recessed part 320, and the second fixing part 330 has a reinforcing rib. It is understood that the reinforcing rib can specifically enhance the deformation resistance of the corresponding part. The first fixing part 310 is connected to the top wall 220, and the second fixing part 330 is connected to the side wall 230. Both of them need to bear the weight and vibration load of the bracket and the oiling pipe 400. The reinforcing rib can prevent the fixing part from bending or breaking due to concentrated force, and ensure the reliability of the fixing to the top wall 220 and the side wall 230.

[0063] The recessed part 320 is used to fix the refueling pipeline 400 and is in a recessed shape. Its structure is prone to collapse due to pipeline compression or vibration. The reinforcing rib can improve the supporting rigidity of the recessed part 320, prevent it from deforming and failing to stably clamp the pipeline, and ensure that the pipeline installation posture does not shift.

[0064] On the other hand, the reinforcing ribs can optimize the load transmission path. Even if only a single part is reinforced, the load borne by that part can be distributed to other fixed parts, avoiding local overload damage. At the same time, the reinforcing ribs can improve the strength within the limited wet area 700 without significantly increasing the overall thickness of the bracket. This not only avoids occupying extra assembly space and causing component interference, but also extends the service life of the bracket, further ensuring the long-term stable cooperation between the refueling pipeline 400 and the refueling port 210.

[0065] In other embodiments, please refer to Figure 1 and Figure 2 The fuel filler cap mounting structure also includes a side panel 500, which is located on the outside of the rear wheel arch panel 200. At least a portion of the side wall 230 is fixed to the side panel 500. It is understood that the side panel 500, as an important load-bearing structure on the outer side of the vehicle body, can work together with the side wall 230 to provide support, significantly improving resistance to deformation. Simultaneously, the side panel 500, together with the side wall 230, can prevent external water from entering the vehicle interior, further reducing the risk of water leakage inside the car.

[0066] The side wall 230 needs to maintain the distance from the inner wheel cover 100 to ensure the space of the wet area 700, and also needs to fix the second fixing part 330 of the mounting bracket 300. The reinforcement of the outer side panel 500 can prevent the side wall 230 from bending or shifting due to bearing the weight of the bracket, the fuel line 400 or the vehicle vibration load, ensuring the stability of the lateral space of the wet area 700, and also providing a more stable fixing base for the mounting bracket 300, preventing the bracket from becoming loose due to the deformation of the side wall 230.

[0067] In other embodiments, please refer to Figure 1 and Figure 2The side panel 500 includes a first panel portion 510 and a second panel portion 520. At least a portion of the first panel portion 510 is fixed to the side wall 230. The second panel portion 520 is disposed on the upper side of the first panel portion 510. At least a portion of the second panel portion 520 is spaced apart from the inner wheel cover 100 to form a dry area 800.

[0068] In the above solution, the second plate 520 forms a dry area 800 on the upper side, spaced apart from the inner wheel cover 100, and forms two independent areas with the wet area 700 inside the rear wheel cover outer plate 200. This ensures that the refueling line 400 and the mounting bracket 300 are separated from other parts inside the vehicle in the dry area 800, reducing the chance of water leakage.

[0069] This design ensures that even if a small amount of water remains in the wet zone 700, it can be confined within the wet zone 700, preventing water from crossing the zone and contacting the interior components of the dry zone 800. This reduces the possibility of water intruding into critical areas of the vehicle, effectively isolating the refueling line 400 from other interior components, cutting off the leakage path, and ultimately reducing the likelihood of leakage. It also avoids the risk of water indirectly seeping into the vehicle due to the proximity of the refueling line 400, brackets, and components in the dry zone 800.

[0070] In other embodiments, please refer to Figure 2 and Figure 3 The fuel filler port installation structure also includes a fuel filler door 600, which is located on the outer panel 200 of the rear wheel arch or the outer panel 500 of the side wall. The fuel filler door 600 can selectively open or close the fuel filler port 210.

[0071] As an example, the refueling door 600 can be installed on the outer side panel 500, which has a first through hole. The first through hole and the refueling port 210 are positioned opposite each other. The refueling door 600 can selectively open or close the first through hole so that the refueling pipeline 400 can be connected to the outside when the refueling port 210 is open.

[0072] As an example, the refueling port mounting structure also includes a mounting base, which is disposed at the refueling port 210 and the first through hole. The end of the refueling pipeline 400 is engaged with the mounting base, and a refueling gate 600 is disposed at the mounting base to selectively open or close the refueling port 210.

[0073] In the above solution, the fuel filler door 600 can directly block the fuel filler neck 210 when it is closed, preventing external impurities such as rainwater, dust, and mud from entering the fuel filler neck 210 during vehicle operation. This prevents impurities from clogging the fuel filler pipe 400 or affecting fuel cleanliness. It also reduces structural damage caused by external foreign objects (such as small stones or branches) colliding with the fuel filler neck 210, protecting the mating parts between the fuel filler neck 210 and the fuel filler pipe 400.

[0074] Furthermore, its installation position fits the exterior layout of the vehicle body, does not occupy the internal space of the wet zone 700 or dry zone 800, and does not interfere with the normal operation of the mounting bracket 300 and the refueling pipeline 400, ensuring that the overall structure and function do not affect each other, and further guaranteeing the stable operation of the refueling system.

[0075] In other embodiments, a sealant layer is provided between the side panel 500 and the rear wheel arch panel 200, and the sealant layer surrounds the filler neck 210. It is understood that the sealant layer can precisely fill the tiny gaps formed between the side panel 500 and the rear wheel arch panel 200 during assembly, preventing rainwater and car wash water from seeping into the gaps between the side panel 500 and the rear wheel arch panel 200 during vehicle operation. It also directly blocks the path of water seepage around the filler neck 210, preventing water from entering the dry area 800 and causing leakage, further reducing the risk of leakage. Simultaneously, it can prevent dust, mud, and other impurities from accumulating near the filler neck 210 through the gaps, protecting the mating parts of the filler neck 210 and the filler pipe 400 from the influence of impurities.

[0076] On the other hand, the sealant layer can enhance the tightness of the connection between the side panel 500 and the rear wheel arch panel 200 while sealing, reduce the relative displacement or friction between the two panels when the vehicle bumps and vibrates, avoid long-term vibration causing the connection between the two panels to loosen, thereby consolidating the installation position stability of the filler neck 210, preventing the filler neck 210 from shifting due to loosening of the surrounding structure, indirectly ensuring the fitting accuracy between the filler pipe 400 and the filler neck 210, and at the same time improving the structural rigidity of the connection area between the two panels, helping to maintain the integrity and sealing of the boundary of the wet area 700.

[0077] As an example, the sealant layer may be an expanding adhesive, and this application does not limit this to.

[0078] In other embodiments, please refer to Figure 2 and Figure 3 The refueling pipeline 400 includes a flange 410 and a pipe body 420. The flange 410 is sleeved on the pipe body 420 and fixed to the mounting bracket 300. The mounting bracket 300 has a mounting hole 340. The pipe body 420 passes through the mounting hole 340, and the end of the pipe body 420 is fitted to the refueling port 210.

[0079] Understandably, after the flange 410 is fitted onto the pipe body 420 and fixed to the mounting bracket 300, the surface contact of the flange 410 replaces the single line contact fixation of the pipe body 420. This can significantly distribute the weight and vibration load borne by the pipe body 420, preventing the pipe body 420 from loosening or deforming due to localized stress concentration. At the same time, the rigid connection between the flange 410 and the mounting bracket 300 can limit the radial sway of the pipe body 420, ensuring that the pipe body 420 always maintains the preset installation posture, which helps to improve the installation accuracy of the refueling pipeline 400.

[0080] On the other hand, the mounting hole 340 of the mounting bracket 300 forms a through-positioning of the pipe body 420, which can accurately limit the axial direction and spatial position of the pipe body 420, prevent the pipe body 420 from shifting due to vehicle bumps, and thus ensure the fitting accuracy between the end of the pipe body 420 and the filler port 210, and reduce positional deviation.

[0081] In a specific embodiment, the flange 410 and the pipe body 420 are connected to form a whole. After the mounting bracket 300 is fixed to the rear wheel cover outer plate 200, the pipe body 420 is passed through the mounting hole 340 and fixed to the mounting bracket 300 through the flange 410, which improves the installation accuracy.

[0082] Secondly, embodiments of this application provide a vehicle including the fuel filler port mounting structure described in any of the embodiments.

[0083] The vehicle proposed according to the second aspect of this application can significantly reduce the risk of water leakage and impurity intrusion during vehicle operation, avoid damage to electrical components and interior trim due to water leakage, reduce refueling problems caused by loose or misaligned refueling lines 400, ensure long-term stable operation of the vehicle's fuel supply system, and improve the overall reliability of the vehicle.

[0084] On the other hand, by fixing the mounting surface of the refueling flange 410 with a bracket, the installation accuracy of the refueling pipeline 400 is improved, ensuring the fit with the small door, making it less likely to get stuck during installation, and achieving a certain degree of weight reduction.
