Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and specifically proposes a vehicle refueling port structure and a vehicle. Background Art

[0002] During the production of some vehicle models, since the fuel tank and the chassis are not pre-fixed, the fuel tank has less constraints on the installation of the fuel filler pipe. Therefore, an assembly port can be opened at a suitable position on the wheel arch, and the fuel filler port housing can be directly sealed at the assembly port. The fuel filler pipe and the fuel filler port housing can then be connected by rotating the angle of the fuel filler pipe.

[0003] However, in other models, the fuel tank is pre-integrated with the chassis, which increases the constraint of the fuel tank on the fuel filler pipe, and the range of movement of the fuel filler pipe is smaller, which affects the sealing installation of the fuel filler pipe and the fuel filler port housing and the wheel cover. Summary of the Invention

[0004] The purpose of this application is to solve at least some of the technical problems mentioned above, and this purpose is achieved through the following technical solutions:

[0005] In a first aspect, the present application provides a vehicle fuel filler port structure comprising a wheel housing, a sealing member, a fuel filler pipe, and a fuel filler port housing. The wheel housing has a first assembly port. The sealing member is sealedly connected to the first assembly port and has a second assembly port formed thereon. The fuel filler pipe passes through the second assembly port and is sealedly connected to the outer wall of the fuel filler pipe. The fuel filler port housing is sealedly connected to the portion of the fuel filler pipe that extends beyond the second assembly port.

[0006] In some embodiments, the sealing member includes a first sealing lip, the first sealing lip surrounds the second assembly opening, and the first sealing lip is inclined toward the fuel filling port.

[0007] In some embodiments, a first deformation portion is connected to a side of the first sealing lip facing away from the second assembly opening, and an inclination direction of the first deformation portion is opposite to an inclination direction of the first sealing lip.

[0008] In some embodiments, the fuel filler housing is provided with a third assembly port, and the fuel filler pipe is sealedly connected to the third assembly port; the fuel filler housing includes a second sealing lip, which surrounds the third assembly port and is inclined toward the fuel filler port.

[0009] In some embodiments, an outer edge of the sealing member is provided with a mounting groove, and an inner edge of the first assembly opening is clamped in the mounting groove.

[0010] In some embodiments, the seal is provided with a fourth assembly port, and the vehicle refueling port structure further includes a drain pipe, one end of which is connected to the interior of the refueling port housing, and the other end passes through the fourth assembly port and its outer wall is sealed to the fourth assembly port.

[0011] In some embodiments, the sealing member includes a third sealing lip, the third sealing lip encloses the fourth assembly opening, and the third sealing lip is inclined in a direction away from the fuel filling port.

[0012] In some embodiments, a second deformation portion is connected to a side of the third sealing lip facing away from the fourth assembly opening, and an inclination direction of the second deformation portion is opposite to an inclination direction of the third sealing lip.

[0013] In some embodiments, the seal includes a seal body, a folded edge and a lifting portion. The folded edge is distributed at the edge of the seal body and is arranged at an angle to the seal body. The lifting portion extends in the opposite direction to the folded edge.

[0014] In a second aspect, the present application proposes a vehicle comprising the vehicle refueling port structure of the first aspect.

[0015] The technical solution proposed in this application has at least the following technical effects:

[0016] In this application, a seal is added to seal the first assembly opening, and a second assembly opening is provided on the seal for the fuel filler pipe to pass through, replacing the fuel filler housing's direct seal with the first assembly opening. This allows the first assembly opening to be opened wider, allowing for a suitable position to accommodate the fuel filler pipe, resolving the issue of limited fuel filler pipe movement hindering installation. Furthermore, the seal is sealed to the wheel arch, and the fuel filler pipe is sealed to the seal and fuel filler housing, preventing water or other impurities from the wheel from entering the space between the wheel arch and the side panel, thus ensuring that the environment within the passenger compartment is not affected.

[0026] To make the contents of the embodiments of this application clearer, the following description will be made in conjunction with the accompanying drawings. It is understood that the contents mentioned below are only some of the embodiments of this application, and all embodiments are listed in detail. Therefore, without inventive work, other embodiments obtained based on the following embodiments fall within the scope of protection of this application.

[0027] It should be understood that the terms used herein are for the purpose of describing specific embodiments only and are not intended to strictly limit the technical solutions unless the context clearly indicates otherwise. For example, the use of "a," "an," and "the" to modify a feature does not exclude the possibility that the feature may be plural in other embodiments.

[0028] It should be understood that the terms "include," "comprising," and "having" are open-ended, indicating the presence of the stated features but not excluding the possibility of additional features in the embodiment. Similarly, when terms such as first, second, etc. are used herein to describe multiple features, they are merely used to distinguish one feature from another and do not imply a sequence or order unless the context clearly indicates otherwise.

[0029] It should be understood that, unless the context clearly indicates otherwise, the terms "disposed," "connected," and "installed" should be interpreted broadly. For example, they may refer to fixed, detachable, or integral connections; they may be directly connected or indirectly connected through a medium. Those skilled in the art will understand the specific meanings of these terms in the context of the text based on the specific circumstances.

[0030] In addition, for the convenience of description, the text will use terms of spatial relative relationships to illustrate the position of one feature relative to another feature, such as "inside", "outside", "end", "side", "upper", "middle", "lower", "high", "lower", "axial", "circumferential", "radial", "horizontal", "vertical", "first direction", "second direction", etc. It can be understood that the spatial relative relationship between two features should include other specific situations in addition to those shown in the drawings of the specification.

[0031] The embodiments of the present application are described below in conjunction with the drawings. It can be understood that the technical features involved in the different embodiments described below can be combined with each other as long as there is no conflict between them.

[0032] Reference Figures 1 to 5 ,in, Figure 1 and Figure 2 The main features of this embodiment can be representatively illustrated. First, the embodiments of the present application provide a vehicle fuel filler port structure, which includes a wheel housing 10, a seal 20, a fuel filler pipe 30, and a fuel filler port housing 40. The wheel housing 10 is provided with a first assembly port 101. The seal 20 is sealedly connected to the first assembly port 101 and is provided with a second assembly port 201. The fuel filler pipe 30 passes through the second assembly port 201 and is sealedly connected to the outer wall of the fuel filler pipe 30. The fuel filler port housing 40 is sealedly connected to the portion of the fuel filler pipe 30 that extends beyond the second assembly port 201.

[0033] In this embodiment, a seal 20 is added to seal the first assembly opening 101, and a second assembly opening 201 is provided on the seal 20 for the fuel filler pipe 30 to pass through. This replaces the fuel filler housing 40 directly sealing the first assembly opening 101. This allows the first assembly opening 101 to be opened wider, allowing for a suitable position to accommodate the fuel filler pipe 30, thus resolving the issue of limited movement of the fuel filler pipe 30 hindering installation. Furthermore, the seal 20 is sealedly connected to the wheelhouse 10, and the fuel filler pipe 30 is sealedly connected to the seal 20 and fuel filler housing 40. This prevents water or other impurities from the wheel beneath the wheelhouse 10 from entering the space between the wheelhouse 10 and the side panel 60, thus ensuring that the environment within the passenger compartment is not affected.

[0034] It can be understood that when the degree of freedom of the fuel filler pipe 30 is low, for example, the fuel tank connected to the fuel filler pipe 30 is pre-integrated on the chassis, or other reasons make it difficult to assemble the fuel filler pipe 30 and the fuel filler port housing 40, this embodiment adopts a larger first assembly port 101 on the wheel cover 10, and can also leave sufficient operating space for the assembly between the fuel filler pipe 30 and the fuel filler port housing 40, making the assembly process more convenient.

[0035] Specifically, during assembly, the fuel filler pipe 30 can be first passed through the first assembly port 101 of the wheel cover 10, and the second assembly port 201 of the seal 20 can be passed through (at this time the seal 20 has not yet been assembled on the wheel cover 10), and then the fuel filler pipe 30 and the fuel filler port housing 40 can be assembled, so as to fully utilize the operating space provided by the first assembly port 101; after the fuel filler pipe 30 and the fuel filler port housing 40 are assembled, the seal 20 is pulled down to achieve sealing between the seal 20 and the first assembly port 101 of the wheel cover 10.

[0036] It should be noted that the seal 20 is a flexible structure, and the fuel filler housing 40 is at least partially flexible (so that in conventional vehicles, the fuel filler housing 40 can be directly and sealedly connected to the wheel arch 10). The end of the fuel filler pipe 30 is a rigid structure. (Both the fuel filler housing 40 and the seal 20 are flexible structures, making it difficult to directly and effectively seal them together.)

[0037] Optionally, the sealing member 20 is made of EPDM (Ethylene Propylene Diene Monomer) material. It should be understood that the sealing member 20 may also be made of TPV or other soft rubber materials.

[0038] In addition, refer to Figure 1 and Figure 4 The fuel filler housing 40 includes a first portion 405 and a second portion 406. The first portion 405 is a flexible structure that provides a sealable connection to the fuel filler pipe 30 (the fuel filler pipe 30 is terminated with a hard pipe head, which passes through the seal 20 and the first portion 405 of the fuel filler housing 40). The second portion 406 is connected to the vehicle's side panel 60. Since the wheelhouse 10 and the side panel 60 are connected to the passenger compartment, a seal 20 is required to prevent water from entering between the wheelhouse 10 and the side panel 60 from below. Furthermore, a fuel filler port is provided where the second portion 406 connects to the side panel 60, which is sealed by a fuel cap.

[0039] In some embodiments, emphasis is placed on Figure 2 The sealing member 20 includes a first sealing lip 202 , which encloses the second assembly opening 201 , and the first sealing lip 202 is inclined toward the fuel filling port.

[0040] In this embodiment, the inclined first sealing lip 202 forms the second assembly opening 201, which can provide a guide when the fuel filler pipe 30 passes through the seal 20 and can easily deform to facilitate the alignment and passage of the fuel filler pipe 30; at the same time, the inclined first sealing lip 202 can press against the outer wall of the fuel filler pipe 30 to ensure a sealing effect.

[0041] Specifically, a first sealing head 204 is provided at the inner ring of the first sealing lip 202 , and the first sealing head 204 is pressed tightly against the outer wall of the refueling pipe 30 . The first sealing head 204 has a certain strength and does not allow friction and tearing to occur, thereby further ensuring the sealing effect and structural stability.

[0042] In some embodiments, reference Figure 2 A first deformation portion 203 is connected to a side of the first sealing lip 202 facing away from the second assembly opening 201 , and an inclination direction of the first deformation portion 203 is opposite to an inclination direction of the first sealing lip 202 .

[0043] In this embodiment, a first deformation portion 203 is provided around the second assembly opening 201, and the inclination direction of the first deformation portion 203 is opposite to the inclination direction of the first sealing lip 202, thereby increasing the deformation amount of the fuel filler pipe 30 when passing through the second assembly opening 201, making it easier to assemble the fuel filler pipe 30 and the sealing member 20, and at the same time making the deformation rebound force greater, thereby enhancing the sealing effect at the second assembly opening 201.

[0044] In some embodiments, reference Figure 2 The fuel filler port housing 40 is provided with a third assembly port 401, and the fuel filler pipe 30 is sealedly connected to the third assembly port 401; the fuel filler port housing 40 includes a second sealing lip 402, which surrounds the third assembly port 401, and the second sealing lip 402 is inclined toward the fuel filler port.

[0045] In this embodiment, the inclined second sealing lip 402 forms a third assembly opening 401, which can provide a guiding effect when the fuel filler pipe 30 passes through the fuel filler port housing 40, and can easily deform to facilitate the alignment and passage of the fuel filler pipe 30; at the same time, the inclined second sealing lip 402 can press against the outer wall of the fuel filler pipe 30 to ensure a sealing effect.

[0046] Specifically, a second sealing head 403 is provided at the inner ring of the second sealing lip 402. The second sealing head 403 is pressed tightly against the outer wall of the refueling pipe 30. The second sealing head 403 has a certain strength and does not allow friction and tearing to occur, thereby further ensuring the sealing effect and structural stability.

[0047] In some embodiments, reference Figure 2 The outer edge of the sealing member 20 is provided with a mounting groove 205 , and the inner edge of the first assembly opening 101 is clamped in the mounting groove 205 .

[0048] In this embodiment, the inner edge of the first assembly opening 101 is clamped in the mounting groove 205, the connection is firm, and the seal between the seal 20 and the wheel cover 10 is achieved. Figure 2 The outer edge of the seal 20 is provided with a first flange 206 and a second flange 207 spaced apart in an upper and lower manner, and an installation groove 205 is formed between the first flange 206 and the second flange 207. The first flange 206 and the second flange 207 have a certain strength to ensure the connection stability between the seal 20 and the first assembly port 101 of the wheel cover 10.

[0049] In some embodiments, reference Figure 1 、 Figure 2 and Figure 5 The seal 20 is provided with a fourth assembly port 208 , and the vehicle refueling port structure further includes a drain pipe 50 , one end of which is connected to the interior of the refueling port housing 40 , and the other end of the drain pipe 50 passes through the fourth assembly port 208 and its outer wall is sealed and connected to the fourth assembly port 208 .

[0050] In this embodiment, during refueling, if it rains, some rainwater will enter the fuel filler housing 40 through the fuel filler port. Drain pipe 50 is used to drain this water below the wheel arch 10 to prevent it from affecting refueling. Furthermore, seal 20 provides support for drain pipe 50, preventing it from shaking and causing unusual noise. Seal 20 is also sealed to drain pipe 50, preventing water from entering the space between wheel arch 10 and side panel 60 through fourth assembly opening 208.

[0051] Specifically, refer to Figure 1 、 Figure 2 and Figure 4 The first portion 405 and the second portion 406 of the fuel filler housing 40 are arranged along the wheel housing 10 and the side panel 60, respectively. The seal 20 is distributed along the wheel housing 10, and the drain pipe 50 should be kept vertically drained as much as possible. Figure 2 , the drain pipe 50 and the sealing member 20 are not necessarily perpendicular. More specifically, referring to Figure 2 and Figure 4 The second portion 406 of the fuel filler housing 40 is provided with a drain nozzle 404, and the drain pipe 50 is connected to the drain nozzle 404. It should be noted that the drain pipe 50 has a certain hardness to facilitate its penetration through the seal 20 and sealing connection with the seal 20. Optionally, the drain pipe 50 is made of PP (Polypropylene).

[0052] In some embodiments, reference Figure 2The sealing member 20 includes a third sealing lip 209 , which encloses a fourth assembly opening 208 , and the third sealing lip 209 is inclined away from the fuel filling port.

[0053] In this embodiment, the inclined third sealing lip 209 forms a fourth assembly opening 208, which can provide a guiding function when the drain pipe 50 passes through the seal 20, and is easy to deform, making it convenient for the drain pipe 50 to align and pass through; at the same time, the inclined third sealing lip 209 can press against the outer wall of the drain pipe 50 to ensure the sealing effect.

[0054] Specifically, a third sealing head 211 is provided at the inner ring of the third sealing lip 209 , and the third sealing head 211 is pressed tightly against the outer wall of the drain pipe 50 . The third sealing head 211 has a certain strength and does not allow friction and tearing to occur, thereby further ensuring the sealing effect and structural stability.

[0055] In some embodiments, reference Figure 2 A second deformation portion 210 is connected to a side of the third sealing lip 209 facing away from the fourth assembly opening 208 , and an inclination direction of the second deformation portion 210 is opposite to an inclination direction of the third sealing lip 209 .

[0056] In this embodiment, a second deformation portion 210 is provided at the fourth assembly port 208, and the inclination direction of the second deformation portion 210 is opposite to the inclination direction of the third sealing lip 209, thereby increasing the deformation amount of the drain pipe 50 when passing through the fourth assembly port 208, making it more convenient to assemble the drain pipe 50 and the seal 20, and at the same time making the deformation rebound force greater, thereby enhancing the sealing effect at the fourth assembly port 208.

[0057] In some embodiments, reference Figure 5 The seal 20 includes a seal body 212, a folded edge 213 and a lifting portion 214. The folded edge 213 is distributed along the edge of the seal body 212 and is arranged at an angle to the seal body 212. The lifting portion 214 extends in the opposite direction to the folded edge 213.

[0058] In this embodiment, the folded edge 213 serves to strengthen the seal 20 and facilitates the worker to pull down the seal 20 so that the installation groove 205 of the seal 20 is assembled with the first assembly opening 101 of the wheel cover 10. In addition, the lifting portion 214 serves to facilitate the worker to pull up the seal 20 so that the seal 20 is separated from the wheel cover 10, thereby facilitating the removal and replacement of the seal 20.

[0059] In a second aspect, an embodiment of the present application provides a vehicle including the vehicle refueling port structure of the first aspect. Therefore, the vehicle of the second aspect has all the technical effects of the vehicle refueling port structure of the first aspect, and its specific technical effects are not further described here.

[0060] It should be understood that the vehicle of this embodiment also includes other components, such as a power system, a control system, etc., and these other components will not be described in detail.

[0061] Optionally, the vehicle proposed in this embodiment may be, but is not limited to, a fuel vehicle, a hybrid vehicle, a flying vehicle, etc.

[0062] In particular, the term "and / or" in this application should be understood as follows:

[0063] In the first case, the term “and / or” located between a first subject and a second subject includes any one of the following meanings: (1) only the first subject; (2) only the second subject; and (3) the first subject and the second subject.

[0064] In the second case, the term "and / or" between the last two entities in three or more entities means including at least any one of the entities. For example, "the first entity, the second entity and / or the third entity" has the same meaning as "the first entity and / or the second entity and / or the third entity", specifically including the following combinations: (1) only the first entity; (2) only the second entity; (3) only the third entity; (4) the first entity and the second entity without the third entity; (5) the first entity and the third entity without the second entity; (6) the second entity and the third entity without the first entity; and (7) the first entity, the second entity and the third entity;

[0065] In addition, the character “ / ” in this application indicates that the objects before and after it are in an “or” relationship.

[0066] Finally, although the above content describes the embodiments of the present application in conjunction with the accompanying drawings, those skilled in the art can also make various modifications and variations without departing from the concept of the present application, and such modifications and variations shall fall within the scope of protection of the present application.
