Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a fuel filler pipe assembly and a vehicle. Background Technology

[0002] The fuel filler hose assembly on a vehicle serves as the connection between the fuel nozzle and the fuel tank. The fuel nozzle delivers fuel to the tank via the hose assembly. The end of the fuel filler hose assembly typically protrudes from the side panel of the vehicle. However, with the diversification of vehicle models, the shape of the side panel varies significantly, leading to changes in the installation space and position of the fuel filler hose assembly. Sometimes, to accommodate the shape of the side panel, the end of the fuel filler hose assembly cannot achieve the ideal shape for connecting with the fuel nozzle. Consequently, when the fuel nozzle connects to the fuel filler hose assembly and delivers fuel, localized congestion can easily occur at the fuel outlet of the fuel nozzle, causing the nozzle to skip or spray back, thus reducing the smoothness of fuel dispensing. Therefore, improving the smoothness of fuel dispensing has become a pressing issue that needs to be addressed. Summary of the Invention

[0003] In view of this, this application provides a fuel filler pipe assembly and a vehicle that can improve the smoothness of fuel filling.

[0004] On one hand, embodiments of this application provide a refueling pipe assembly, which includes a connector, a guide pipe, and a limiting member;

[0005] The insertion tube has a cavity, the cavity has an insertion interface in the insertion / removal direction, and the end of the cavity away from the insertion interface is connected to the oil guide tube;

[0006] The limiting member is located inside the insertion cavity. The limiting member has a limiting hole, which is opposite to the oil inlet end of the oil guide pipe. The oil outlet pipe of the refueling gun can enter the insertion cavity through the insertion interface and pass through the limiting hole.

[0007] Optionally, the axial direction of the limiting hole is the same as the axial direction of the oil inlet end of the oil guide pipe.

[0008] Optionally, the limiting member includes a first pipe segment and a second pipe segment connected together;

[0009] The two ends of the first pipe section are respectively connected to the inner wall of the insertion cavity and the second pipe section. The first pipe section has a first through hole, and the diameter of the first through hole gradually decreases in the direction from the insertion pipe to the oil guide pipe.

[0010] The second pipe section is provided with the limiting hole, which is connected to the first through hole.

[0011] Optionally, the limiting member further includes a third tube segment, the two ends of the first tube segment being connected to the second tube segment and the third tube segment respectively, and the outer wall of the third tube segment abutting against the inner wall of the insertion cavity;

[0012] The third pipe section has a second through hole, and the insertion interface, the second through hole, the first through hole and the limiting hole are sequentially connected and coaxial.

[0013] Optionally, the inner walls of the first pipe section, the second pipe section, and the third pipe section are all smooth surfaces.

[0014] Optionally, the limiting member includes a limiting plate and a guide tube;

[0015] The limiting plate is provided with the limiting hole, and the outer wall of the limiting plate is connected to the inner wall of the insertion cavity;

[0016] The guide tube is located between the limiting plate and the insertion interface. One end of the guide tube is connected to the edge of the limiting hole, and the other end extends toward the inner wall of the insertion cavity and is connected to the inner wall of the insertion cavity.

[0017] Optionally, the inner wall of the guide tube is a smooth surface.

[0018] Optionally, the refueling pipe assembly further includes a threaded ring located within the insertion cavity, with one end of the threaded ring connected to the insertion interface and the other end extending toward the limiting member.

[0019] Optionally, the refueling pipe assembly further includes a mounting plate sleeved on the insertion pipe, the mounting plate having at least one mounting hole.

[0020] On the other hand, this application also provides a vehicle that includes a refueling pipe assembly as described in any one of the above embodiments of this application.

[0021] The refueling hose assembly provided in this application includes a connector, a fuel guide tube, and a limiting member. The connector has a cavity with an insertion interface in the insertion / removal direction, allowing the refueling nozzle to be inserted into the cavity via the insertion interface in the insertion / removal direction. The end of the cavity furthest from the insertion interface is connected to the fuel guide tube, allowing fuel in the refueling nozzle to be guided into the fuel guide tube through the cavity. The limiting member is located within the cavity and has a limiting hole. Since the limiting hole is opposite to the fuel inlet end of the fuel guide tube, when delivering fuel, the refueling nozzle's outlet tube can be inserted into the limiting hole through the cavity, ensuring the outlet of the refueling nozzle's outlet tube is aligned with the fuel inlet end of the fuel guide tube for fuel refueling. In other words, the limiting hole of the limiting member limits the insertion direction of the refueling nozzle's outlet tube, ensuring fuel is aligned with the fuel inlet end of the fuel guide tube for refueling, preventing localized fuel accumulation at the outlet of the refueling nozzle's outlet tube, and preventing nozzle skipping or backflow, thereby improving the smoothness of fuel refueling.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] In the embodiments of this application, directional terms such as "upper," "lower," and "side" are generally used in the following ways: Figure 1 The relative positions shown are based on established rules, and these directional terms are used merely to more clearly describe the structures and their relationships, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged. Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art.

[0037] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0038] Combination Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a refueling pipe assembly, which includes a plug pipe 100, an oil guide pipe 200, and a limiting member 300.

[0039] The connector 100 has a cavity 101, and the cavity 101 has an interface 102 in the insertion / removal direction. The end of the cavity 101 away from the interface 102 is connected to the fuel guide pipe 200. Thus, the fuel nozzle 400 can be inserted into the cavity 101 in the insertion / removal direction through the interface 102, and fuel can be introduced into the fuel guide pipe 200 through the cavity 101.

[0040] The limiting member 300 is located within the insertion cavity 101 and has a limiting hole 301. The limiting hole 301 is opposite to the oil inlet end of the oil guide pipe 200. The oil outlet pipe 401 of the fuel dispenser 400 can enter the insertion cavity 101 via the insertion interface 102 and pass through the limiting hole 301. It should be noted that the length of the limiting member 300 can be adjusted according to the dimensions of the insertion pipe 100. Because the limiting hole 301 is opposite to the oil inlet end of the oil guide pipe 200, when the fuel dispenser 400 is delivering fuel, the oil outlet of the fuel dispenser 400's oil outlet pipe 401 can be aligned with the oil inlet end of the oil guide pipe 200 for fuel dispensing.

[0041] In other words, the limiting hole 301 of the limiting member 300 in the fuel filler assembly provided in this application embodiment can limit the insertion direction of the fuel outlet pipe 401 of the fuel filler nozzle 400, ensuring that the fuel can be filled into the fuel inlet of the fuel guide pipe 200, avoiding local accumulation of fuel at the fuel outlet of the fuel outlet pipe 401 of the fuel filler nozzle 400, thereby preventing the fuel filler nozzle 400 from jumping or spraying back, improving the smoothness of the fuel filling process of the fuel filler nozzle 400, and thus ensuring that the whole vehicle can meet the requirements of evaporative emissions and fuel emission.

[0042] The following is in conjunction with the appendix Figures 1 to 4 The details and functions of the refueling pipe assembly provided in the embodiments of this application will be described in more specific and detailed manner.

[0043] like Figure 2 As shown, in some embodiments, the limiting hole 301 and the oil outlet pipe 401 of the fuel nozzle 400 are fitted with a clearance. Thus, the limiting hole 301 can both position the oil outlet pipe 401 of the fuel nozzle 400 and prevent scratches on the oil outlet pipe 401 of the fuel nozzle 400.

[0044] like Figure 2As shown, in some embodiments, the axial direction of the limiting hole 301 is the same as the axial direction of the inlet end of the fuel guide pipe 200. With this configuration, when the fuel outlet pipe 401 of the fuel dispenser 400 is inserted into the limiting hole 301, it ensures that the axial direction of the outlet of the fuel outlet pipe 401 of the fuel dispenser 400 is also the same as the axial direction of the inlet end of the fuel guide pipe 200. Therefore, the outlet of the fuel outlet pipe 401 of the fuel dispenser 400 can be aligned with the inlet end of the fuel guide pipe 200 for refueling without misalignment. This prevents fuel from accumulating locally at the outlet of the fuel outlet pipe 401 of the fuel dispenser 400, preventing the fuel dispenser 400 from skipping or spraying back, and improving the smoothness of fuel dispensing.

[0045] like Figure 2 As shown, in some embodiments, the limiting member 300 includes a first pipe segment 302 and a second pipe segment 303 connected together. The two ends of the first pipe segment 302 are connected to the inner wall of the insertion cavity 101 and the second pipe segment 303, respectively. The first pipe segment 302 has a first through hole 304, the diameter of which gradually decreases in the direction from the insertion pipe 100 to the oil guide pipe 200. The second pipe segment 303 is provided with a limiting hole 301, which communicates with the first through hole 304. It should be noted that by connecting the first pipe segment 302 to the inner wall of the insertion cavity 101, the limiting member 300 can be fixed within the insertion pipe 100. As the diameter of the first through hole 304 gradually decreases, when the oil outlet pipe 401 of the fuel nozzle 400 is inserted into the first through hole 304 through the insertion interface 102, the hole wall of the first through hole 304 can guide the oil outlet pipe 401 of the fuel nozzle 400, thereby facilitating the insertion of the oil outlet pipe 401 of the fuel nozzle 400 into the limiting hole 301.

[0046] like Figure 2 As shown, in some embodiments, the diameter of the first through hole 304 decreases linearly in the direction from the insertion pipe 100 to the oil guide pipe 200. That is, the inner wall of the first through hole 304 is funnel-shaped, which can improve the guiding effect on the oil outlet pipe 401 of the refueling nozzle 400.

[0047] like Figure 2 As shown, in some embodiments, the outer diameter of the first pipe segment 302 gradually decreases in the direction from the insertion pipe 100 to the oil guide pipe 200, and the outer diameter of the second pipe segment 303 is equal to the outer diameter of the end of the first pipe segment 302 away from the insertion port 102 and smaller than the inner diameter of the insertion cavity 101. This arrangement makes it easier to insert the limiting member 300 into the insertion cavity 101 during assembly, preventing the limiting member 300 from rubbing against the inner wall of the insertion cavity 101.

[0048] like Figure 2As shown, in some embodiments, the limiting member 300 further includes a third pipe segment 305. The two ends of the first pipe segment 302 are connected to the second pipe segment 303 and the third pipe segment 305 respectively. The outer wall of the third pipe segment 305 abuts against the inner wall of the insertion cavity 101. The third pipe segment 305 has a second through hole 306. The insertion port 102, the second through hole 306, the first through hole 304, and the limiting hole 301 are sequentially connected and coaxial. It should be noted that the third pipe segment 305 is cylindrical. By providing the third pipe segment 305, the contact area between the limiting member 300 and the inner wall of the insertion cavity 101 can be increased, thereby improving the stability of the connection between the limiting member 300 and the insertion pipe 100, preventing the limiting member 300 from detaching from the insertion pipe 100, and thus improving the reliability of the refueling pipe assembly.

[0049] Combination Figure 2 As shown, in some embodiments, the third pipe section 305 is provided with at least one groove (not shown in the figure), the opening of which faces the inner wall of the insertion cavity 101. The inner wall of the insertion cavity 101 is provided with at least one protrusion (not shown in the figure), wherein the protrusion engages in the corresponding groove. It should be noted that during assembly, the limiting member 300 moves axially along the insertion cavity 101 until the protrusion engages in the corresponding groove. The cooperation between the protrusion and the groove makes it easier to position the limiting member 300, thereby improving the assembly efficiency of the limiting member 300 and the insertion pipe 100.

[0050] In some embodiments, the third pipe section 305 is provided with two grooves, which are arranged opposite to each other. This arrangement can prevent the limiting member 300 from being misaligned and ensure that the axial direction of the limiting hole 301 is the same as the axial direction of the oil inlet end of the oil guide pipe 200.

[0051] In some embodiments, the third pipe section 305 is provided with an annular groove (not shown in the figure), the opening of which faces the inner wall of the insertion cavity 101. The inner wall of the insertion cavity 101 is provided with an annular flange (not shown in the figure) circumferentially, wherein the annular flange engages within the annular groove. It should be noted that during assembly, the limiting member 300 moves axially along the insertion cavity 101 until the annular flange engages within the annular groove. The engagement of the annular groove and the annular flange facilitates the positioning of the limiting member 300, improving the assembly efficiency of the limiting member 300 and the insertion pipe 100.

[0052] In some embodiments, the third tube segment 305 is welded to the wall of the insertion cavity 101. This improves the stability of the connection between the limiting member 300 and the insertion tube 100.

[0053] like Figure 2As shown, in some embodiments, the inner walls of the first pipe section 302, the second pipe section 303, and the third pipe section 305 are all smooth surfaces. This design prevents the outlet of the fuel nozzle 400 from rubbing against the inner wall of the limiting member 300 when the outlet pipe 401 is inserted into the cavity 101, thus avoiding damage to the limiting member 300 and extending its service life, which in turn extends the service life of the fuel nozzle assembly.

[0054] like Figure 3 As shown, in some embodiments, the limiting member 300 further includes a first sealing component 311, which is rotatably connected to the end of the second pipe segment 303 away from the insertion port 102. The first sealing component 311, when pressed, can rotate around the connection point between itself and the second pipe segment 303 to connect the limiting hole 301 and the oil guide pipe 200. After pressure release, the first sealing component 311 rotates to its initial position, closing the limiting hole 301, under gravity. It should be understood that the pressure on the first sealing component 311 refers to the thrust exerted on the first sealing component 311 by the port of the oil outlet pipe 401 of the fuel nozzle 400 when the oil outlet pipe 401 of the fuel nozzle 400 is inserted into the insertion cavity 101 and moves inward. Pressure release refers to the removal of the oil outlet pipe 401 of the fuel nozzle 400 from the insertion cavity 101 until the oil outlet pipe 401 of the fuel nozzle 400 separates from the first sealing component 311. It should be noted that by setting the first sealing component 311, the limiting hole 301 and the fuel guide pipe 200 can be connected when refueling is needed. When refueling is not required by the fuel nozzle 400, the first sealing component 311 can be used to seal the limiting hole 301, thereby preventing external impurities from entering the fuel guide pipe 200 through the limiting hole 301, improving the cleanliness of the fuel in the fuel guide pipe 200, and also preventing impurities from causing wear on the inner wall of the fuel guide pipe 200, thus increasing the service life of the refueling pipe assembly.

[0055] like Figure 3As shown, in some embodiments, the first sealing assembly 311 includes a first rotating plate 312 and a second rotating plate 313, which are arranged opposite to each other. The first rotating plate 312 is rotatably connected to the end of the second pipe segment 303 away from the insertion port 102 and extends inward. The second rotating plate 313 is rotatably connected to the end of the second pipe segment 303 away from the insertion port 102 and extends inward. When pressed, both the first rotating plate 312 and the second rotating plate 313 rotate towards the side away from the insertion port 102 to connect the limiting hole 301 and the oil guide pipe 200. After the pressure is released, the first rotating plate 312 and the second rotating plate 313 rotate to the initial position of closing the limiting hole 301 under gravity. At this time, the side of the first rotating plate 312 facing the second rotating plate 313 abuts against the side of the second rotating plate 313 facing the first rotating plate 312. It should be noted that the shapes of the first rotating plate 312 and the second rotating plate 313 match the shape of the limiting hole 301. For example, when the limiting hole 301 is circular, the first rotating plate 312 and the second rotating plate 313 can both be semi-circular. It should be noted that when the oil outlet pipe 401 of the fuel nozzle 400 moves toward the oil guide pipe 200, the first rotating plate 312 and the second rotating plate 313 can be pushed away by the oil outlet pipe 401 of the fuel nozzle 400 more easily.

[0056] like Figure 4 As shown, in some embodiments, the limiting member 300 includes a limiting plate 307 and a guide tube 308. The limiting plate 307 has a limiting hole 301, and the outer wall of the limiting plate 307 is connected to the inner wall of the insertion cavity 101. The guide tube 308 is located between the limiting plate 307 and the insertion interface 102. One end of the guide tube 308 is connected to the edge of the limiting hole 301, and the other end extends toward the inner wall of the insertion cavity 101 and is connected to the inner wall of the insertion cavity 101. It should be noted that the outer wall of the limiting plate 307 and the inner wall of the insertion cavity 101 can be connected by welding, thereby improving the stability of the connection between the limiting member 300 and the insertion tube 100. The guide tube 308 can guide the oil outlet tube 401 of the fuel nozzle 400, making it easier for the oil outlet tube 401 of the fuel nozzle 400 to be quickly inserted into the limiting hole 301.

[0057] like Figure 4As shown, in some embodiments, the limiting member 300 further includes a second sealing component 314, which is rotatably connected to the portion of the limiting plate 307 located around the limiting hole 301. The second sealing component 314, when pressed, can rotate around the connection point between itself and the limiting plate 307 to connect the limiting hole 301 and the oil guide tube 200. After pressure release, the second sealing component 314 rotates to its initial position, closing the limiting hole 301, under gravity. It should be understood that the pressure on the second sealing component 314 refers to the thrust exerted on the second sealing component 314 by the port of the oil outlet tube 401 of the fuel nozzle 400 when the oil outlet tube 401 of the fuel nozzle 400 is inserted into the cavity 101 and moves inward. Pressure release refers to the removal of the oil outlet tube 401 of the fuel nozzle 400 from the cavity 101 until the oil outlet tube 401 of the fuel nozzle 400 separates from the second sealing component 314. It should be noted that by setting the second sealing component 314, the limiting hole 301 and the fuel guide pipe 200 can be connected when refueling is needed. When refueling is not required by the fuel nozzle 400, the second sealing component 314 can be used to seal the limiting hole 301, thereby preventing external impurities from entering the fuel guide pipe 200 through the limiting hole 301, improving the cleanliness of the fuel in the fuel guide pipe 200, and also preventing impurities from causing wear on the inner wall of the fuel guide pipe 200, thus increasing the service life of the refueling pipe assembly.

[0058] like Figure 4 As shown, in some embodiments, the second sealing assembly 314 includes a third rotating plate 315 and a fourth rotating plate 316, which are disposed opposite to each other. The portion of the third rotating plate 315 surrounding the limiting hole 301 of the limiting plate 307 is rotatably connected and extends inward. The portion of the fourth rotating plate 316 surrounding the limiting hole 301 of the limiting plate 307 is rotatably connected and extends inward. When pressed, both the third rotating plate 315 and the fourth rotating plate 316 rotate toward the side away from the insertion interface 102 to connect the limiting hole 301 and the oil guide pipe 200. After the pressure is released, the third rotating plate 315 and the fourth rotating plate 316 rotate to the initial position of closing the limiting hole 301 under gravity. At this time, the side of the third rotating plate 315 facing the fourth rotating plate 316 abuts against the side of the fourth rotating plate 316 facing the third rotating plate 315. It should be noted that the shapes of the third rotating plate 315 and the fourth rotating plate 316 match the shape of the limiting hole 301. For example, when the limiting hole 301 is circular, the third rotating plate 315 and the fourth rotating plate 316 can both be semi-circular. It should also be noted that when the oil outlet pipe 401 of the fuel nozzle 400 moves towards the oil guide pipe 200, the third rotating plate 315 and the fourth rotating plate 316 can be pushed open more easily by the oil outlet pipe 401 of the fuel nozzle 400.

[0059] like Figure 4As shown, in some embodiments, the inner diameter of the guide tube 308 gradually decreases from the insertion port 102 toward the oil guide tube 200. Thus, the guide tube 308 can gradually guide the oil outlet tube 401 of the refueling gun 400 into the limiting hole 301.

[0060] like Figure 4 As shown, in some embodiments, the inner diameter of the guide tube 308 decreases linearly from the insertion port 102 toward the oil guide tube 200. That is, the inner wall of the guide tube 308 is funnel-shaped, which can improve the guiding effect on the oil outlet tube 401 of the refueling nozzle 400.

[0061] like Figure 4 As shown, in some embodiments, a first baffle 105 is connected to the inner wall of the insertion cavity 101. One end of the first baffle 105 is connected to the circumferential inner wall of the insertion cavity 101, and the other end extends into the insertion cavity 101. The side of the first baffle 105 facing the insertion interface 102 abuts against the side of the limiting plate 307 away from the insertion interface 102. It should be noted that when assembling the limiting member 300 in the insertion cavity 101, the first baffle 105 can position the assembly position of the limiting member 300. When the limiting plate 307 moves to abut against the first baffle 105, the limiting member 300 is assembled in place. This improves assembly efficiency.

[0062] like Figure 4 As shown, in some examples, the first baffle 105 has a third through hole 106, which is coaxial with the limiting hole 301, and the diameter of the third through hole 106 is not less than the diameter of the limiting hole 301. This arrangement ensures that the oil outlet pipe 401 of the fuel nozzle 400 will not be blocked by the first baffle 105 and can smoothly pass through the limiting hole 301.

[0063] like Figure 4 As shown, in some embodiments, the inner wall of the guide tube 308 is a smooth surface. This design prevents the outlet of the fuel nozzle 400 from rubbing against the inner wall of the guide tube 308 when the outlet pipe 401 is inserted into the cavity 101, thus preventing damage to the guide tube 308 and extending the service life of the limiting member 300, which in turn extends the service life of the fuel nozzle assembly.

[0064] like Figure 4As shown, in some embodiments, the refueling hose assembly further includes a threaded ring 500 located within the cavity 101. One end of the threaded ring 500 is connected to the insertion interface 102, and the other end extends toward the limiting member 300. It should be noted that the threaded ring 500 has an insertion hole 501 communicating with the cavity 101. The threaded ring 500 can provide initial guidance and positioning for the refueling hose. The threaded ring 500 can be fixed to the inner wall of the cavity 101 by welding. In some embodiments, the threaded ring 500 includes a connected first portion 502 and a second portion 503. The first portion 502 abuts against the inner wall of the cavity 101, and the second portion 503 extends away from the insertion interface 102. The axial direction of the end of the second portion 503 away from the insertion interface 102 is the same as the axial direction of the limiting hole 301, and the inner diameter of the second portion 503 gradually decreases in the direction from the insertion interface 102 toward the oil guide pipe 200. Therefore, when the fuel outlet pipe 401 of the fuel nozzle 400 is inserted into the cavity 101, it can pass through the first part 502 and the second part 503 in sequence, and then enter the limiting member 300. The second part 503 can play a preliminary guiding role for the fuel outlet pipe 401 of the fuel nozzle 400, which makes it easier for the fuel outlet pipe 401 of the fuel nozzle 400 to be aligned with the fuel guide pipe 200, ensuring smooth fuel refueling.

[0065] like Figure 2 As shown, in some embodiments, the refueling hose assembly further includes a mounting plate 600, which is sleeved on the connector 100. The mounting plate 600 has at least one mounting hole. It should be noted that the mounting hole aligns with a corresponding positioning hole on the vehicle body or fuel tank and is connected by bolts or other fasteners. This allows the refueling hose assembly to be securely mounted on the fuel tank or vehicle body.

[0066] On the other hand, this application embodiment also provides a vehicle, which includes the refueling pipe assembly as described in any one of the above embodiments of this application. It should be noted that the composition and function of the refueling pipe assembly in the vehicle provided in this application embodiment are the same as those of the refueling pipe assembly described in any one of the above embodiments of this application, so they will not be repeated here. Since the limiting member 300 in the refueling pipe assembly ensures that the fuel can be aligned with the inlet end of the fuel guide pipe 200 for refueling, it can prevent local accumulation of fuel at the outlet of the fuel outlet pipe 401 of the refueling nozzle 400, thereby preventing the refueling nozzle 400 from skipping or spraying back, improving the smoothness of the fuel refueling process of the refueling nozzle 400, and thus ensuring that the whole vehicle can meet the requirements for evaporative emissions and refueling emissions.
