Description

Technical Field

[0001] This application relates to the field of vehicle parts technology, and in particular to a detergent filling structure and vehicle. Background Technology

[0002] In order to promptly wipe away rainwater from the windshield during rainy or snowy weather, vehicles are equipped with windshield wipers. Therefore, a washer fluid reservoir for supplying the washer fluid to the windshield wipers is located in the engine compartment.

[0003] Traditional wash tank filling ports are typically blow-molded into a single piece on the top of the tank. However, the location of the wash tank can vary significantly between different vehicle models, and the filling port needs to be positioned on top of the engine compartment. This requires the filling port to be configured with different lengths and extension directions. Therefore, the washing tank filling ports for different vehicle models need to be redesigned and molded to match the spatial arrangement of different peripheral components, which greatly increases manufacturing costs. Utility Model Content

[0004] In view of this, this application aims to propose a detergent filling structure to improve the adaptability and versatility of the detergent tank filling port on different vehicle models.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A cleaning solution filling structure includes a filling pipeline connecting to a cleaning solution tank and a filling port inserted into the filling pipeline; the filling port is provided with an installation structure for fixing the filling port to a fixed base component, and a guide structure is provided between the filling port and the filling pipeline; the filling port can be inserted into a set position on the filling pipeline under the guidance of the guide structure, and when the filling port is located in the set position, the installation structure is in an installation position that can be assembled and connected with the fixed base component.

[0006] Furthermore, the filling port includes an upper section and a lower section connected vertically. The top of the upper section is open for injecting washing fluid, and the lower section is inserted into the filling pipeline. The guiding structure and the mounting structure are both located on the lower section.

[0007] Furthermore, both the upper and lower sections are constructed as circular tubes, with the radial dimension of the upper section being larger than that of the lower section, and a transition section with a gradually changing radial dimension is provided between the upper and lower sections.

[0008] Furthermore, the mounting structure includes a fixed support foot integrally formed on the filling port; the fixed support foot is provided with a connecting hole for connecting the fixed base component and a positioning pin that positions and cooperates with the fixed base component, and the distance D between the positioning pin and the connecting hole is more than 10mm.

[0009] Furthermore, the filling pipeline includes a plug-in portion that mates with the filling port, and a main body portion that connects the plug-in portion and the washing liquid tank; the connection between the main body portion and the plug-in portion is provided with an outwardly protruding baffle, which forms an obstruction to the filling port in the axial direction of the plug-in portion during the insertion of the filling port.

[0010] Furthermore, the outer wall of the filling port is provided with an alignment rib, and the blocking platform is provided with an alignment protrusion. When the filling port is inserted into the set position, the alignment rib and the alignment protrusion are directly opposite each other.

[0011] Furthermore, the top of the filling pipeline is provided with a plug-in portion for insertion into the filling port. The guiding structure includes a guide groove formed on the plug-in portion and a guide protrusion provided on the inner wall of the filling port. During the insertion process of the filling port, the guide protrusion slides within the guide groove. When the filling port is inserted into the set position, the guide protrusion slides to the end of the guide groove.

[0012] Furthermore, the guide groove includes an insertion section and a locking section connected in sequence. The insertion section is arranged along the axial direction of the insertion portion, and the locking section is arranged along the circumferential direction of the insertion portion. The inner wall of the locking section is provided with a locking protrusion. During the insertion process of the filling port, the guide protrusion slides in the insertion section as the filling port and the insertion portion move relative to each other in the axial direction of the insertion portion, and slides in the locking section as the filling port and the insertion portion rotate relative to each other. The guide protrusion can pass over the locking protrusion and be locked at the end of the locking section.

[0013] Furthermore, the insertion portion includes a guide section and a sealing section connected vertically, with the guide groove disposed on the guide section; the sealing section is provided with a sealing ring, which forms a seal between the sealing section and the filling port.

[0014] Compared with related technologies, this application has the following advantages: (1) The washing liquid filling structure of this application is configured with a split filling port for the washing liquid tank and a filling pipeline for connecting the filling port; the length of the filling pipeline and its layout can be flexibly set according to the different configuration conditions of the installation space in the front engine compartment of different models, so as to install and fix the filling port in a suitable position, which is conducive to improving the adaptability and universality of the filling port of the washing liquid tank on different models.

[0015] Meanwhile, a guide structure is set between the filling port and the filling pipeline. By using the guiding and position limiting function of the guide structure, it can be ensured that the filling port inserted into the filling pipeline can reach the accurate assembly position. Thus, the installation structure on the filling port can be used to securely fix the filling port to the pre-designed fixed base on the vehicle body, ensuring the smooth assembly and implementation of the entire washing liquid filling structure.

[0016] (2) The filling port is designed with two sections, an upper section and a lower section, which can be used for filling the washing liquid and for inserting into the filling pipeline, respectively. For the case where the lower section is inserted into the filling pipeline, the guiding structure and the installation structure are set on the lower section at the same time, which greatly shortens the distance between the guiding structure and the installation structure. This is conducive to improving the guiding and position limiting role of the guiding structure, so as to avoid the deviation between the position defined by the guiding structure and the assembly position of the installation structure, thereby realizing the smooth installation of the installation structure on the fixed base. Moreover, setting the installation structure on the lower section also ensures the structural stability of the lower section, and the fixed base can be used to form good support for the top of the filling port and the filling pipeline at the same time.

[0017] (3) The filling port adopts a round or conical tube shape, which has the advantages of standardized structure and easy processing and forming. The transition section is set between the upper and lower sections, which helps to increase the radial dimension of the top opening of the upper section, thus making it more convenient to add washing liquid into the washing liquid tank.

[0018] (4) The installation structure adopts a fixed support foot integrally formed on the filling port, which is conducive to improving the structural stability between the entire installation structure and the filling port. At the same time, positioning pins and connecting holes are set on the fixed support foot, and the distance dimension D between the two is set within a reasonable range. When the fixed support foot is tightened to the fixed base component with bolts, it can prevent the fixed support foot from rotating due to the torque generated by tightening the bolts, thus having a good anti-rotation effect.

[0019] (5) To meet the insertion requirements of the filling port and the filling pipeline, the top part of the filling pipeline is designed as a plug-in part for receiving the filling port insertion, and a baffle is set at the connection between the plug-in part and the main body of the filling pipeline. This can form a blockage when the filling port is inserted into the axial position during the insertion process, which not only has a good limiting effect, but also ensures the connection stability between the filling pipeline and the filling port.

[0020] (6) Alignment ribs are installed on the outer wall of the filling port, and corresponding alignment protrusions are installed on the baffle platform to form a good identification reminder; it can be used to determine whether the filling port is correctly positioned in the circumferential direction of the filling pipeline, so as to ensure that the filling port is exactly in the set position. This provides good conditions for the subsequent accurate alignment and installation of the fixed support on the fixed base.

[0021] (7) Based on the above-mentioned plug-in part, the guide structure is designed as a sliding fit between the guide groove and the guide protrusion, which can ensure that the filling port is inserted into the filling pipeline along the correct path; and the position of the end of the guide groove corresponds to the above-mentioned set position. When the guide protrusion slides to the end of the guide groove, it can ensure that the filling port can be accurately positioned to the set position required on the filling pipeline; the whole guide structure has the advantages of simple structure, easy molding, good guiding and position limiting effect.

[0022] (8) The guide groove is designed as two connected sections. The filling port is inserted along the axial direction of the insertion section by the insertion section. With the setting of the above-mentioned baffle, after the filling port is inserted into the axial position, the filling port is rotated. At this time, the locking section plays a guiding role. The locking protrusion in the locking section can lock and limit the guide protrusion on the inner wall of the filling port to the end position of the entire guide groove, thereby ensuring that the filling port can accurately reach the required set position.

[0023] (9) The insertion part is divided into two parts: a guide section and a sealing section. The guide section can guide the insertion and limit the position of the filling port. Then, a sealing ring is set on the sealing section to form a good sealing effect between the filling port and the filling pipeline, preventing leakage at the connection between the filling pipeline and the filling port.

[0024] Another object of this application is to provide a vehicle in which the wash fluid tank adopts the wash fluid filling structure described in this application. The vehicle of this application has the technical advantages of the aforementioned wash fluid filling structure. Attached Figure Description

Detailed Implementation

[0027] To make the technical solution and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0029] Furthermore, it should be stated in the description of this application that if terms such as "up," "down," "left," "right," "front," "back," "inner," or "outer" appear, they are based on the orientation or positional relationship shown in the accompanying drawings and are only for the purpose of describing this application and making the expression clear and concise, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, a connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0031] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] Traditional wash tank filling ports are typically blow-molded into a single piece on the top of the tank. However, the location of the wash tank can vary significantly between different vehicle models, and the filling port needs to be positioned on top of the engine compartment. This requires the filling port to be configured with different lengths and extension directions. Therefore, the washing tank filling ports for different vehicle models need to be redesigned and molded to match the spatial arrangement of different peripheral components, which greatly increases manufacturing costs.

[0033] Moreover, the fixed installation structure of the filling port of the traditional washing liquid tank is not entirely reasonable. During installation, the mounting holes on the filling port bracket often cannot be aligned with the mounting holes on the sheet metal parts on the vehicle body that serve as the fixing base, resulting in the inability to smoothly insert bolts and affecting the convenience of installation.

[0034] Meanwhile, when the bolts are tightened during installation, the support of the filling port is subjected to torque, and the entire filling port will rotate in the direction of torque along with the support. This creates a tearing and pulling effect between the filling port and the washing tank body, affecting the stability and sealing of the connection between the filling port and the washing tank.

[0035] In view of the above-mentioned problems in the related technologies, this application innovatively proposes a brand-new washing liquid filling structure, which can improve the adaptability and versatility of the filling port 3 of the washing liquid tank 1 on different vehicle models.

[0036] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0037] An embodiment of the first aspect of this application provides a washer fluid filling structure, applied to the installation scenario of a windshield wiper*1; an exemplary structure is as follows: Figure 1 , Figure 2 and Figure 3 As shown.

[0038] Overall, the cleaning solution filling structure includes a filling pipeline 2 connecting to the cleaning solution tank 1, and a filling port 3 inserted into the filling pipeline 2. The filling port 3 is provided with an installation structure for fixing the filling port 3 to the fixed base 6, and a guide structure is provided between the filling port 3 and the filling pipeline 2. Simultaneously, guided by the guide structure, the filling port 3 can be inserted into a predetermined position on the filling pipeline 2, and when the filling port 3 is in the predetermined position, the installation structure is in an installation position that allows for assembly and connection with the fixed base 6.

[0039] Based on the above overall design concept, the washing liquid tank 1 is equipped with a split filling port 3 and a filling pipeline 2 for connecting the filling port 3. The length and layout of the filling pipeline 2 can be flexibly set according to the different configuration conditions of the installation space in the front engine compartment of different models, so as to install and fix the filling port 3 in a suitable position, which is conducive to improving the adaptability and versatility of the filling port 3 of the washing liquid tank 1 on different models.

[0040] Furthermore, a guide structure is set between the filling port 3 and the filling pipeline 2. By using the guiding and position limiting function of the guide structure, it can be ensured that the filling port 3 inserted into the filling pipeline 2 can reach the accurate assembly position. Thus, the installation structure on the filling port 3 can be used to securely fix the filling port 3 to the pre-designed fixed base 6 on the vehicle body, ensuring the smooth assembly and implementation of the entire washing liquid filling structure.

[0041] It should be noted that, based on the above overall design concept, the technical solution of this application can adopt a variety of different specific implementation structures, forms, or configuration sequences. For example, the above-mentioned guiding structure can be in the form of a chute, or the tubular insert structure of the filling pipe 2 and the filling port 3 can be used in conjunction with a limiting structure to achieve guidance and position limitation. The installation structure can adopt different structural forms such as mounting brackets or mounting feet, and can be implemented by plugging, bolting, or snapping to achieve fixed installation on the surrounding body sheet metal and other fixed base components 6. The specific arrangement sequence and assembly method of the washing liquid tank 1, filling pipe 2, filling port 3, and fixed base component 6 can also be flexibly adjusted. For the parts required for the implementation of the overall solution but not covered in the above overall setup, reasonable and flexible design can be made by referring to mature setting methods in the field and the actual situation during implementation, which will not be elaborated here. The specific implementation schemes described below in this embodiment are only one of the many solutions that can be formed by the above combinations and variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the various combinations and variations of the above-mentioned specific forms that can form numerous solutions, as well as the specific implementation schemes of this embodiment, are all within the protection scope of this application.

[0042] The following will provide a detailed description of the solution proposed in this application. To facilitate a better understanding of the solution, it is necessary to first explain the practical application of the cleaning fluid filling structure before proceeding with the detailed description. Given the large number of functional components such as the engine, battery, and air conditioning system in the forward engine compartment, the space arrangement is often poor, resulting in the cleaning fluid tank 1 being positioned too low or too far to the side, making the location of the filling port 3 at its top inconvenient for filling. The cleaning fluid filling structure of this application, by providing a connecting filling pipe 2 at the top of the cleaning fluid tank 1, allows for flexible arrangement of the filling pipe 2's routing and length, regardless of the location of the filling port 3, thus placing the filling port 3 in a suitable position for operation.

[0043] like Figure 1 As shown, the washing fluid tank 1 is installed at a low position in the forward engine compartment via the mounting bracket 10, while the filling port 3 needs to be located at the top of the forward engine compartment for the filling operation of the washing fluid. At this point, by setting up a filling pipeline 2 between the filling port 3 and the washing fluid tank 1, and fixing the filling port 3 to the surrounding fixed base 6, the space arrangement problem of the washing fluid tank 1 in the forward engine compartment is well solved.

[0044] As a component of the detergent tank 1 that can be adapted to various vehicle models, the filling port 3 has good versatility and adaptability. It can be produced separately without the need for different molds for different vehicle models, thereby reducing manufacturing costs. Of course, a cover plate mounting bracket 300 can be set on the top of the filling port 3 for the installation of the cover plate 4. The cover plate 4 is mounted on the cover plate mounting bracket 300 in a flip-up hinged manner. Normally, the filling port 3 is closed. When the detergent is being filled, the cover plate 4 is flipped to open the top of the filling port 3.

[0045] Continue as Figures 4 to 7 As shown, as a preferred exemplary implementation among various feasible solutions, the filling port 3 in this embodiment includes an upper section 30 and a lower section 32 that are connected vertically. The top opening of the upper section 30 is used for injecting washing fluid, while the lower section 32 is inserted into the filling pipeline 2. In this regard, preferably, both the guiding structure and the installation structure are provided on the lower section 32.

[0046] The filling port 3 is designed with two sections, an upper section 30 and a lower section 32, which can be used for filling the washing liquid and for inserting into the filling pipeline 2, respectively. For the insertion of the lower section 32 into the filling pipeline 2, the guiding structure and the installation structure are simultaneously located on the lower section 32. This significantly shortens the distance between the guiding structure and the installation structure, enhancing the guiding and position-limiting functions of the guiding structure. This prevents deviations between the position defined by the guiding structure and the assembly position of the installation structure, thus ensuring smooth mounting of the installation structure on the fixed base 6. Furthermore, placing the installation structure on the lower section 32 ensures the structural stability of the area where the lower section 32 is located, allowing the fixed base 6 to provide good support for both the filling port 3 and the top of the filling pipeline 2.

[0047] Regarding the specific design of the filling port 3, various technical solutions are available; for example, it can be a square tube or a round tube. However, to achieve better technical results, preferably, in this embodiment, both the upper section 30 and the lower section 32 of the filling port 3 are constructed as round tubes, and the radial dimension of the upper section 30 is larger than that of the lower section 32, with a transition section 31 between the upper section 30 and the lower section 32 where the radial dimension gradually changes. The use of round or tapered tubes for each section of the filling port 3 provides advantages such as standardized structure and ease of processing. The transition section 31 between the upper section 30 and the lower section 32 helps to increase the radial dimension of the open top of the upper section 30, thereby making it more convenient to add washing liquid into the washing liquid tank 1.

[0048] Still referencing Figure 3As shown, as a preferred exemplary implementation among various feasible solutions, the installation structure of this embodiment includes a fixed support leg 33 integrally formed on the filling port 3; the fixed support leg 33 is provided with a connecting hole 330 for connecting to the fixed base 6, and a positioning pin 332 for positioning and engaging with the fixed base 6; at the same time, the distance D between the positioning pin 332 and the connecting hole 330 is more than 10mm. The installation structure adopts the form of a fixed support leg 33 integrally formed on the filling port 3, which is beneficial to improving the structural stability between the entire installation structure and the filling port 3. At the same time, the fixed support leg 33 is provided with a positioning pin 332 and a connecting hole 330, and the distance D between them is set within a reasonable range. When the fixed support leg 33 is tightened to the fixed base 6 with bolts, it can prevent the fixed support leg 33 from rotating due to the torque generated by tightening the bolts, thus having a good anti-rotation effect.

[0049] Understandably, when the fixed support 33 on the filling port 3 is bolted to the fixed plate 60 on the fixed base 6, during the tightening of the bolts, the fixed support 33 on the filling port 3 is subjected to torque. If the aforementioned locating pin 332 is not provided, the entire filling port 3 will rotate in the direction of torque due to the torque on the fixed support 33, thus creating a tearing and pulling effect between the filling port 3 and the filling pipeline 2, thereby affecting the stability and sealing of the connection between the filling port 3 and the filling pipeline 2. The anti-rotation function provided by the locating pin 332 effectively prevents the fixed support 33 from rotating relative to the fixed base 6 during the assembly process.

[0050] Of course, to improve the structural strength of the fixed support leg 33, a certain number of reinforcing ribs 331 can be provided on the fixed support leg 33. Corresponding to the setting of the positioning pin 332 on the fixed support leg 33, the fixed base component 6 used to support the fixed support leg 33 should be provided with a corresponding positioning hole 601. When the fixed support leg 33 is pressed against the fixed plate 60 of the fixed base component 6, the positioning pin 332 is inserted into the positioning hole 601 on the fixed plate 60. Then, the bolt is screwed onto the fixed plate 60 after passing through the connecting hole 330 on the fixed support leg 33. In order to improve the bolt connection performance between the bolt and the fixed base component 6, a welding nut 600 can be added to the fixed base component 6, and the bolt can be screwed onto the welding nut 600 to improve the connection reliability of the bolt on the fixed base component 6.

[0051] In addition, to enhance the structural strength of the fixed plate 60, a reinforcing flange 602 can be provided on the side of the fixed plate 60 to improve the support strength of the fixed plate 60.

[0052] Continue as Figure 3 and Figure 6As shown, as a preferred exemplary implementation among various feasible solutions, the filling pipeline 2 in this embodiment includes an insertion portion that mates with the filling port 3, and a main body portion 20 connecting the insertion portion and the washing liquid tank 1. The connection between the main body portion 20 and the insertion portion is provided with an outwardly protruding baffle 200. During the insertion of the filling port 3, the baffle 200 forms an axial obstruction to the filling port 3. To meet the insertion requirements of the filling port 3 and the filling pipeline 2, the top portion of the filling pipeline 2 is designed as an insertion portion to receive the insertion of the filling port 3, and a baffle 200 is provided at the connection between the insertion portion and the main body portion 20 of the filling pipeline 2. This baffle can form an obstruction to the axial insertion of the filling port 3 during the insertion process, providing not only a good limiting effect but also ensuring the connection stability between the filling pipeline 2 and the filling port 3.

[0053] Based on the above configuration, preferably, the outer wall of the filling port 3 in this embodiment is provided with an alignment rib 321, and the stop platform 200 is provided with an alignment protrusion 201. When the filling port 3 is inserted into the set position, the alignment rib 321 and the alignment protrusion 201 are directly opposite each other. Providing the alignment rib 321 on the outer wall of the filling port 3 and the corresponding alignment protrusion 201 on the stop platform 200 can form a clear identification reminder; it can be used to determine whether the position of the filling port 3 in the circumferential direction of the filling pipeline 2 is correct, ensuring that the filling port 3 is exactly in the set position. This provides good conditions for the subsequent accurate alignment and installation of the fixing leg 33 on the fixing base 6.

[0054] Furthermore, the top of the filling pipe 2 in this embodiment is provided with a plug-in portion for insertion into the filling port 3. The aforementioned guiding structure includes a guide groove 210 formed on the plug-in portion and a guide protrusion 320 provided on the inner wall of the filling port 3. During the insertion process of the filling port 3, the guide protrusion 320 slides within the guide groove 210; when the filling port 3 is inserted to the set position, the guide protrusion 320 slides to the end of the guide groove 210.

[0055] Based on the above-mentioned insertion part, the guide structure is designed in the form of a sliding fit between the guide groove 210 and the guide protrusion 320, which can ensure that the filling port 3 is inserted into the filling pipeline 2 along the correct path; and the position of the end of the guide groove 210 corresponds to the above-mentioned set position. When the guide protrusion 320 slides to the end of the guide groove 210, it can ensure that the filling port 3 can be accurately positioned at the required set position on the filling pipeline 2; the entire guide structure has the advantages of simple structure, easy molding, and good guiding and position limiting effect.

[0056] Based on the above configuration, it is preferable to design the guide groove 210 in segments. Specifically, the guide groove 210 in this embodiment includes an insertion segment 2101 and a locking segment 2102 connected in sequence. The insertion segment 2101 is arranged along the axial direction of the insertion portion, and the locking segment 2102 is arranged along the circumferential direction of the insertion portion. Moreover, the inner wall of the locking segment 2102 is provided with a locking protrusion 2103. Based on the above configuration, during the insertion process of the filling port 3, the guide protrusion 320 slides within the insertion segment 2101 as the filling port 3 and the insertion portion move relative to each other in the axial direction of the insertion portion, and slides within the locking segment 2102 as the filling port 3 and the insertion portion rotate relative to each other. The guide protrusion 320 can pass over the locking protrusion 2103 and be locked at the end of the locking segment 2102. The guide groove 210 is designed as two connected sections. The insertion section 2101 guides the filling port 3 to be inserted axially along the insertion part. With the setting of the stop platform 200, after the filling port 3 is inserted into place axially, the filling port 3 is rotated. At this time, the locking section 2102 plays a guiding role. The locking protrusion 2103 in the locking section 2102 can lock and limit the guide protrusion 320 on the inner wall of the filling port 3 to the end position of the entire guide groove 210, thereby ensuring that the filling port 3 can accurately reach the required set position.

[0057] Additionally, in this embodiment, as Figure 6 As shown, as a preferred exemplary embodiment among various feasible solutions, the aforementioned insertion portion includes a guide section 21 and a sealing section 22 connected vertically. Based on this, the guide groove 210 is provided on the guide section 21, and a sealing ring 5 is simultaneously provided on the sealing section 22. This sealing ring 5 forms a seal between the sealing section 22 and the filling port 3. Dividing the insertion portion into the guide section 21 and the sealing section 22 allows the guide section 21 to guide the insertion and position of the filling port 3; furthermore, the sealing ring 5 on the sealing section 22 creates a good seal between the filling port 3 and the filling pipeline 2, preventing leakage at the connection between the filling pipeline 2 and the filling port 3.

[0058] Regarding the above-mentioned configuration, in specific implementation and application, mature methods or products in this field can be used, and adjustments can be made based on the convenience, rationality, and applicability of implementation. For example, regarding the configuration and number of the sealing rings 5, two annular sealing grooves 220 can be machined on the outer wall of the sealing section 22, and two sealing rings 5 ​​can be correspondingly equipped. These two sealing rings 5 ​​are then fitted into the sealing grooves 220 located on the sealing section 22. This ensures the secure installation of the sealing rings 5 ​​on the sealing section 22 and prevents the sealing rings 5 ​​from shifting during the insertion of the insertion part into the filling port 3.

[0059] In summary, the detergent filling structure of this embodiment features a separate filling port 3 for the detergent tank 1 and a filling pipe 2 for connecting the filling port 3. The length and routing of the filling pipe 2 can be flexibly adjusted to accommodate different installation space conditions in the engine compartment of various vehicle models, allowing for the installation and fixing of the filling port 3 in a suitable location. This improves the adaptability and versatility of the filling port 3 of the detergent tank 1 across different vehicle models. Furthermore, a guide structure is provided between the filling port 3 and the filling pipe 2. The guiding and position-limiting function of this structure ensures that the filling port 3, inserted into the filling pipe 2, reaches the accurate assembly position. The mounting structure on the filling port 3 then securely fixes it to the pre-designed fixing base 6 on the vehicle body, ensuring the smooth assembly of the entire detergent filling structure.

[0060] An embodiment of the second aspect of this application provides a vehicle having a washer fluid tank 1 for supplying washer fluid to windshield wipers, and the washer fluid tank 1 adopts the washer fluid filling structure provided in Embodiment 1.

[0061] By adopting the cleaning fluid filling structure of this application on the vehicle, the problems of poor installation convenience of the filling port 3 of the cleaning fluid tank 1 and easy rotation of the filling port 3 with torque when installing bolts are effectively solved; at the same time, based on the good versatility and adaptability of the filling port 3, the processing cost can be effectively reduced by changing the structure and manufacturing process of the filling port 3.

[0062] Of particular note is the use of a positioning pin 332 on the fixed support 33 of the filling port 3. This positioning pin 332 engages with the positioning hole 601 on the fixing plate 60, effectively resolving the issue of the fixed support 33 rotating during installation as the mounting bolts rotate. Simultaneously, a guide structure between the filling port 3 and the filling pipeline 2 ensures that the fixed support 33 is precisely aligned with the fixing base 6 while the filling port 3 is connected to the filling pipeline 2. At this point, the connecting hole 330 on the fixed support 33 aligns perfectly with the welding nut 600 on the fixing plate 60, facilitating subsequent installation and fixing of the fixed support 33. This prevents misalignment between the fixed support 33 and the mounting holes on the fixing plate 60 and other fixing base components 6 after the filling port 3 is installed on the filling pipeline 2.
