Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a supply assembly, fuel tank, and vehicle. Background Technology

[0002] Vehicle engine fuel tanks typically use external piping structures to connect filters, pumps, and other components to achieve the pumping and circulation of internal fluids. In designs where methanol is stored inside the fuel tank, due to its corrosive nature, the filters, pumps, and other components are arranged externally. In designs with large fuel tank volumes, the significant drop from the top to the bottom makes an integrated, internal design difficult; therefore, external structures are also used to house the filters, pumps, and other components.

[0003] However, external mounting solutions require multiple brackets to secure components such as filters. Different brackets need to be redesigned for different vehicle models, resulting in low standardization. Utility Model Content

Detailed Implementation

[0038] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0039] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0040] This application provides a vehicle. The vehicle includes a fuel tank. For example... Figure 1 and Figure 2As shown, the fuel tank 200 includes a tank body 201, an end cap 202, and a fluid cavity (not shown) disposed within the tank body 201. When the fluid cavity contains gasoline, the fuel tank 200 is a gasoline fuel tank. When the fluid cavity contains methanol, the fuel tank 200 is a methanol fuel tank. The fuel tank 200 is typically cuboid. Therefore, the end cap 202 should be understood as the wall surface of the fuel tank 200 at one end along its length. Furthermore, the end cap 202 can be integrally formed with the tank body 201 or fixedly connected to it, thereby improving the sealing performance of the fluid cavity.

[0041] Combination Figure 2 , Figure 3 and Figure 4 The oil tank 200 of this application includes a supply assembly 100. The supply assembly 100 includes a housing 1, a pressure assembly 2, a filter assembly 3, and a piping assembly 4. The housing 1 is connected to the end cap 202 of the oil tank 200 and includes a main wall 11 and a side wall 12 and a filter tube wall 13 connected to the main wall 11. The side wall 12 encloses an assembly space 14 forming the housing 1. The pressure assembly 2 is disposed in the assembly space 14. The filter tube wall 13 is at least partially disposed in the assembly space 14 and encloses a receiving space 15 forming the housing 1. The filter assembly 3 is disposed in the receiving space 15. The piping assembly 4 communicates with the fluid cavity of the oil tank 200 and includes a pressure inlet pipe 41 and a pressure outlet pipe 42 connected to the pressure assembly 2, and a filter inlet pipe 43 and a filter outlet pipe 44 communicating with the receiving space 15. The filter outlet pipe 44 communicates with the pressure inlet pipe 41. The filter inlet pipe 43 is used to allow fluid to enter the supply assembly 100. The pressure outlet pipe 42 allows fluid to leave the supply assembly 100 and enter the fluid chamber.

[0042] The supply assembly 100 integrates a filter assembly 3 and a pressure assembly 2, thereby achieving fluid filtration and pumping. The housing 1 of the supply assembly 100 is connected to the end cap 202 of the fuel tank 200, and the piping assembly 4 communicates with the fluid chamber of the fuel tank 200. Therefore, the supply assembly 100 can achieve fluid pumping and filtration of the fuel tank 200. Thus, the vehicle does not require additional brackets for connecting and fixing the pressure assembly 2 and filter assembly 3, which helps reduce vehicle design and development costs and facilitates component placement. Furthermore, since the fuel tank 200 equipped with the supply assembly 100 has its own filter assembly 3 and pressure assembly 2, the supply assembly 100 allows the fuel tank 200 to be used in various vehicle models, improving its versatility.

[0043] When the housing 1 is connected to the end cap 202, the assembly space 14 is positioned towards the end cap 202. That is, the main wall 11 and the end cap 202 "clamp" the pressure component 2 in the space they form, which helps to protect the pressure component 2 and thus avoid damage to the pressure component 2 caused by collision and compression after the vehicle is hit.

[0044] Furthermore, when the fuel tank 200 is assembled into the vehicle, it is arranged parallel to the ground in its longitudinal direction. Therefore, the supply assembly 100 is positioned on the end cap 202, which can also prevent damage to the pressure assembly 2 and the filter assembly 3 caused by bumps to the bottom of the vehicle. When the end cap 202 on which the supply assembly 100 is located is positioned facing the front of the vehicle, the supply assembly 100 can also be located away from heat sources such as the vehicle's exhaust pipe, further improving the service life and safety of the supply assembly 100.

[0045] In an embodiment where the oil tank 200 is a methanol oil tank, the supply assembly 100 is located outside the fluid cavity, thus effectively preventing the methanol inside the fluid cavity from corroding the pressure assembly 2 and the filter assembly 3.

[0046] exist Figure 2 and Figure 3 In the illustrated embodiment, an end cap 202 connects two supply assemblies 100. In this embodiment, the fuel tank 200 includes a partition wall (not shown) disposed in the fluid cavity. The partition wall divides the fluid cavity into a first cavity and a second cavity. A piping assembly 4 of one supply assembly 100 communicates with the first cavity, and a piping assembly 4 of the other supply assembly 100 communicates with the second cavity. In other words, the fuel tank 200 is a dual-cavity fuel tank. The first cavity and the second cavity contain different fluids; for example, the first cavity contains methanol, and the second cavity contains gasoline. Thus, one supply assembly 100 is a methanol supply assembly, and the other supply assembly 100 is a gasoline supply assembly.

[0047] As can be seen, this embodiment can further improve the integration of the fuel tank 200, so that the vehicle does not need to set up brackets for support and fixation for the filter assembly 3 and pressure assembly 2 of the gasoline fuel tank and the filter assembly 3 and pressure assembly 2 of the methanol fuel tank, which is conducive to the weight reduction of the vehicle and the universal setting of the fuel tank 200.

[0048] It should be noted that when the oil tank 200 is a dual-chamber oil tank, the oil tank 200 may also have only one supply assembly 100 to supply fluid to one of the chambers. In an example where the oil tank 200 has two supply assemblies 100, the two supply assemblies 100 may be identical or different. This application does not limit this.

[0049] Furthermore, this application does not limit which component the pressure regulating inlet pipe 43 can be directly connected to, as long as the pressure regulating inlet pipe 43 and the pressure outlet pipe 42 ultimately form a complete fluid circuit.

[0050] like Figure 2As shown, in an optional embodiment, the end cap 202 includes a protrusion 2021 that protrudes toward the side of the supply assembly 100. The housing 1 is connected to the protrusion 2021. The protrusion 2021 is provided such that the end of the side wall 12 away from the main wall 11 maintains a certain distance from the end cap 202. In this way, the pressure assembly 2, the filter assembly 3, etc., can protrude toward the end cap 202 from the self-assembly space 14. This arrangement helps to reduce the overall volume of the housing 1, thereby improving the lightweight of the supply assembly 100. Furthermore, in embodiments where the end cap 202 is non-planar, the protrusion 2021 facilitates the formation of a planar connection between the housing 1 and the end cap 202, thereby improving connection stability and connection strength.

[0051] The housing 1 can be directly connected to the side wall 12 and the end cap 202. Or, as... Figure 2 As shown, the housing 1 is provided with a connecting portion 17. The connecting portion 17 is located at one end of the side wall 12 away from the main wall 11 and on the side away from the assembly space 14. The housing 1 is connected to the end cover 202 via the connecting portion 17. The connecting portion 17 can be detachably connected to the end cover 202 via a snap-fit ​​structure, fastener structure, magnetic structure, etc. Of course, the connecting portion 17 can also be fixedly connected to the end cover 202. This application is not limited in this regard. By providing the connecting portion 17, the supply assembly 100 can design the size and position of the connecting portion 17 according to the actual structure of the fuel tank 200, without having to readjust the internal structure of the assembly space 14 according to the structure of the fuel tank 200. This is beneficial to improving the design cost and versatility of the supply assembly 100.

[0052] In embodiments where the fuel tank 200 includes two supply assemblies 100, the connection portion 17 of the two supply assemblies 100 may share a common connection location. For example... Figure 2 As shown, the connecting portion 17 between the upper supply assembly 100 and the lower supply assembly 100 is connected to the same protrusion 2021. This arrangement helps to improve the overall structural compactness of the fuel tank 200 and makes better use of the space of the end cover 202.

[0053] Optionally, in various embodiments, the housing 1 and the piping assembly 4 can be made of ethylene-tetrafluoroethylene copolymer, polyethylene, or polyamide. The housing 1 and the piping assembly 4 can be made of the same or different materials. These materials have high strength and a certain degree of corrosion resistance. Therefore, even if fluid leakage occurs in the fluid cavity, the housing 1 and the piping assembly 4 can maintain material stability, thereby ensuring the structural stability of the supply assembly 100. Furthermore, compared to solutions that use metal supports such as stainless steel to support the filter assembly 3 and the pressure assembly 2, the materials of the housing 1 and the piping assembly 4 in this embodiment help reduce the overall weight of the structure, thereby achieving a lightweight structure for the supply assembly 100.

[0054] It should be noted that the supply assembly 100 may be made of one of the following materials: ethylene-tetrafluoroethylene copolymer, polyethylene, or polyamide, either the housing 1 or only the piping assembly 4.

[0055] In some embodiments, to improve the overall structural strength of the housing 1, the housing 1 further includes a reinforcing structure 16. Optionally, the reinforcing structure 16 is disposed in the assembly space 14, thereby improving the structural strength of the housing 1 from the assembly space 14 side. Figure 3 and Figure 4 As shown, the reinforcing structure 16 connects the side wall 12 and the main wall 11, thereby improving the connection strength between the main wall 11 and the side wall 12. Furthermore, the reinforcing structure 16 can also connect the filter tube wall 13 and the main wall 11, thereby improving the connection strength between the filter tube wall 13 and the main wall 11. The reinforcing structure 16 can be placed in any empty position within the assembly space 14, thus fully utilizing the assembly space 14 to improve the structural strength of the shell 1. Of course, the reinforcing structure 16 can connect only the side wall 12 and the main wall 11, or it can connect only the filter tube wall 13 and the main wall 11.

[0056] Optionally, such as Figure 1 and Figure 2 As shown, the reinforcing structure 16 is disposed on the side of the main wall 11 away from the assembly space 14, thereby improving the structural strength of the main wall 11 from the outside of the housing 1. In this embodiment, the reinforcing structure 16 is a raised rib laid on the side of the main wall 11 away from the assembly space 14. This not only helps to improve the overall structural strength of the main wall 11, but also increases the heat transfer area from inside the assembly space 14 and enables efficient heat dissipation.

[0057] In embodiments where the reinforcing structure 16 is located on the side of the main wall 11 away from the assembly space 14, and in embodiments located within the assembly space 14, the structural strength of the housing 1 is maximized, thereby achieving stable connection and fixation of the internal piping assembly 4, pressure assembly 2, and filter assembly 3. In embodiments where the housing 1 is made of ethylene-tetrafluoroethylene copolymer, polyethylene, or polyamide, the reinforcing structure 16 ensures structural strength of the housing 1 while achieving weight reduction.

[0058] In some embodiments, the opening 131 of the filter tube wall 13 is oriented toward the end cap 202, thereby enabling the assembly and replacement of the filter assembly 3 via one side of the assembly space 14. In an optional embodiment, the filter tube wall 13 is connected to the side wall 12 and includes an opening 131 communicating with the receiving space 15. The receiving space 15 communicates with the side of the side wall 12 away from the assembly space 14 via the opening 131. In this embodiment, the receiving space 15 is not directly connected to the assembly space 14, but rather communicates with the external space of the supply assembly 100 from the side wall 12. Since the assembly space 14 is oriented toward the end cap 202, this embodiment allows maintenance personnel to easily replace and repair the filter assembly 3 from outside the supply assembly 100 without disassembling the housing 1 and the end cap 202.

[0059] Furthermore, the filter tube wall 13 extends from the side wall 12 away from the assembly space 14 to form a protrusion 132. The supply assembly 100 also includes a filter cover 5. The filter cover 5 mates with the protrusion 132 to close the receiving space 15. The mating of the filter cover 5 and the protrusion 132 can be a threaded fit, a snap-fit ​​fit, or a magnetic fit, etc. By providing the protrusion 132 and the filter cover 5, maintenance personnel can easily and manually access the protruding filter cover 5 and expose the receiving space 15 to replace the filter assembly 3. This not only facilitates the assembly of the filter assembly 3 but also improves the efficiency of maintenance and replacement.

[0060] A sealing ring can be provided between the filter cover 5 and the opening 131 to prevent fluid in the receiving space 15 from leaving the receiving space 15 through the gap between the opening 131 and the filter cover 5. Furthermore, an elastic element (not shown) can be provided at the end of the filter cover 5 facing the filter assembly 3. When the filter cover 5 is engaged with the opening 131, the elastic element presses against the filter assembly 3 and remains compressed. Thus, the elastic element can continuously apply a force away from the filter cover 5 to the filter assembly 3 and remain on the side away from the end cap 202, thereby ensuring the fluid filtration effect in the receiving space 15. In addition, the elastic element also applies a force away from the receiving space 15 to the filter cover 5. In embodiments where the filter cover 5 and the protrusion 132 are threaded or snap-fit ​​connected, the elastic element can improve the tightness of the press between the filter cover 5 and the protrusion 132, further ensuring connection stability and fluid sealing, and preventing vibration during vehicle operation from causing the filter cover 5 and the protrusion 132 to disengage.

[0061] Of course, in other embodiments, the closure of the opening 131 can be achieved by fasteners connecting the plate structure to the sidewall 12. Alternatively, the opening 131 can be closed by a plug provided in the accommodating space 15.

[0062] The sidewall 12 includes a first wall 121 and a second wall 122 distributed along the gravity direction Z. In this application, the gravity direction Z is a unidirectional direction, as shown by the arrow in the attached drawing. The neutral distribution of the first wall 121 and the second wall 122 can be understood as follows: when the fuel tank 200 is assembled in the vehicle, the first wall 121 is positioned away from the ground relative to the second wall 122. However, this should not be interpreted as the first wall 121 necessarily being parallel to the second wall 122.

[0063] In an optional embodiment, the pressure assembly 2 and the filter assembly 3 are disposed near the second wall 122. The filter outlet pipe 44 is disposed on the side of the filter tube wall 13 facing the first wall 121. The pressure inlet pipe 41 is disposed near the second wall 122. With the filter outlet pipe 44 disposed on the side of the filter tube wall 13 facing the first wall 121, when fluid enters the accommodating space 15 from the filter inlet pipe 43, the fluid flows towards the second wall 122 under the influence of gravity. Once the accommodating space 15 is completely filled with fluid, it exits from the accommodating space 15 through the filter outlet pipe 44 near the first wall 121, thereby achieving sufficient filtration.

[0064] The pressure inlet pipe 41 is positioned close to the second wall 122, allowing the fluid leaving the accommodating space 15 from the filter outlet pipe 44 to move toward the pressure assembly 2 under the influence of gravity, thereby preventing fluid from accumulating between the filter outlet pipe 44 and the pressure inlet pipe 41 and improving fluid utilization.

[0065] Furthermore, the end of the filter inlet pipe 43 furthest from the accommodating space 15 is positioned close to the first wall 121. This arrangement allows the fluid entering the supply assembly 100 through the filter inlet pipe 43 to have a higher gravitational potential energy, enabling the fluid to smoothly enter the accommodating space 15 for filtration under the influence of gravity, without requiring excessive pump assemblies to provide fluid pressure. Thus, the internal structure of the supply assembly 100 is simplified and lightweight. Figure 3 and Figure 4 As shown, the reinforcing structure 16 is disposed between the first wall 121 and the main wall 11. The reinforcing structure 16 is positioned near the end of the filter inlet pipe 43 furthest from the accommodating space 15. Therefore, the filter inlet pipe 43 is initially arranged along the reinforcing structure 16, then continues to extend near the first wall 121 until it reaches the side wall 12, at which point it changes direction and extends along the direction of gravity Z. In other words, the filter inlet pipe 43 is positioned as close as possible to the side wall 12 of the housing 1, thereby avoiding excessive occupation of space in the assembly space 14 and allowing space to be freed up for the placement of larger pressure components 2, filter components 3, and convenient routing of the piping components 4.

[0066] Combination Figure 2 and Figure 3 In an optional embodiment, a portion of the filter tube wall 13 protrudes from the side of the main wall 11 away from the assembly space 14, such that a portion of the accommodating space 15 is located on the side of the main wall 11 away from the assembly space 14, and another portion is located on the side of the main wall 11 facing the assembly space 14. Compared to a solution where the filter tube wall 13 is entirely located on one side of the assembly space 14, this solution is advantageous for controlling the extension height of the side wall 12, thereby ensuring the structural strength of the housing 1 and the overall volume and weight of the supply assembly 100. Furthermore, this embodiment can also control the distance between the main wall 11 and the end cap 202. This not only controls the overall volume of the tank 200 but also reduces the bending moment that the connection between the housing 1 and the end cap 202 needs to withstand, thereby reducing the strength requirements for the connection between the housing 1 and the end cap 202.

[0067] Since the filter assembly 3 is typically cylindrical, the filter tube wall 13 can also be correspondingly surrounded to form a cylindrical receiving space 15, thereby fitting snugly against the filter assembly 3 and avoiding excessive occupation of unnecessary space. In this embodiment, as... Figure 2 As shown, when the surface of the main wall 11 away from the assembly space 14 is provided with a reinforcing structure 16, the surface of the protruding filter tube wall 13 may not be provided with a reinforcing structure 16, thereby reducing the overall manufacturing difficulty of the housing 1. Of course, in order to further enhance the structural strength of the housing 1, other forms of reinforcing structures 16 may also be provided on the surface of the filter tube wall 13, and this application does not limit this.

[0068] The pressure assembly 2 is described below. Pressure assembly 2 includes a pressure pump 21. A pressure inlet pipe 41 is connected to the pressure pump 21. The pressure pump 21 provides fluid power within the piping assembly 4, thereby ensuring normal pumping of fluid. Optionally, refer to... Figure 2 and Figure 3 Piping assembly 4 includes a three-way valve 45. The three-way valve 45 includes a three-way inlet 451, a return oil outlet 452, and a supply oil outlet 453. The pressure outlet pipe 42 includes a first outlet pipe 421 and a second outlet pipe 422. The three-way inlet 451 is connected to the pressure pump 21. The return oil outlet 452 is connected to the first outlet pipe 421. The supply oil outlet 453 is connected to the second outlet pipe 422.

[0069] The fluid exiting the pressure pump 21 typically needs to flow separately into the return oil tank and the engine compartment. In this embodiment, the supply assembly 100 integrates a three-way valve 45. The three-way valve 45 distributes the fluid exiting the pressure pump 21 to a first outlet pipe 421 and a second outlet pipe 422, thereby facilitating the subsequent connection of the first outlet pipe 421 to the return oil tank line and the second outlet pipe 422 to the engine compartment line. As can be seen, this embodiment eliminates the need for an additional bracket to secure the fuel tank 200 to the vehicle for the three-way valve 45, thus further reducing the number of brackets required for the vehicle, thereby reducing bracket design costs and freeing up space for vehicle component placement.

[0070] In the embodiment shown in the accompanying drawings, the first outlet pipe 421 is disposed near the first wall 121, and the second outlet pipe 422 is disposed near the second wall 122. However, this should be considered exemplary and not restrictive. The first outlet pipe 421 may also be disposed near the second wall 122, and the second outlet pipe 422 may be disposed near the first wall 121. This application is not limiting in this respect.

[0071] The return oil outlet 452 includes an interface end 4521 connected to the first outlet pipe 421. Optionally, the pressure assembly 2 also includes a pressure regulating valve 22 disposed within the interface end 4521 in the return oil outlet 452. The supply assembly 100 of this embodiment also integrates the pressure regulating valve 22 to regulate the fluid pressure, thereby ensuring that the fluid pressure leaving the first outlet pipe 421 is within the optimal range. It should be noted that since the return oil outlet 452 and the supply oil outlet 453 are interconnected, the pressure regulation of the fluid at the return oil outlet 452 by the pressure regulating valve 22 will also have a certain pressure regulating effect on the fluid at the supply oil outlet 453.

[0072] In embodiments where the piping assembly 4 is made of plastic, the metal pressure regulating valve 22 is only located at the interface end 4521. Therefore, compared to embodiments where the three-way valve 45 is an integral metal pressure regulating valve, this embodiment can improve the weight reduction of the supply assembly 100, integrate the pressure regulating valve 22 into the supply assembly 100, and achieve a higher degree of functional integration of the supply assembly 100.

[0073] Pressure assembly 2 includes a controller 23. The controller 23 is electrically connected to the pressure pump 21 to control the pressure pump 21. Optionally, the main wall 11 includes a through-hole (not shown). The controller 23 is disposed in the assembly hole and exposed on the side of the main wall 11 away from the assembly space 14. The controller 23 has a certain heat dissipation requirement. In this embodiment, the supply assembly 100 exposes the controller 23 towards the side away from the assembly space 14, thereby enabling heat exchange with the outside air. This arrangement helps improve heat dissipation of the controller 23 while avoiding negative impacts of the controller 23's heat on the pressure pump 21.

[0074] In the above embodiment, the surface of the pressure pump 21 may be covered with sound insulation materials such as sound insulation cotton, so as to avoid abnormal noise generated by the pressure pump 21 during operation and transmitted through the structure such as the housing 1.

[0075] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
