Description

Technical Field

[0001] This invention belongs to the technical field of car washing systems, and relates to a structure for enlarging the filling port of a washing system and a car. Background Technology

[0002] Because the hood was locked, the washer fluid needed to be added frequently, making it impossible to place the original washer system's filler port inside the front compartment. After collaborative analysis by various departments, it was determined that the washer system would be located inside the left fender at the front of the vehicle, with the guide pipe running across the side beam of the vehicle body, and the filler port positioned below the lower trim panel of the windshield.

[0003] During the vehicle review process, the small X-axis clearance of the windshield water channel, the compact size of the lower windshield trim panel, and the small matching clearance with surrounding parts limited the size of the filling port, resulting in an initial filling port size of only φ29mm. Furthermore, due to the limited Z-axis space of only 72mm, the original washing system did not provide a filling port cap, only a filter to prevent debris from entering. Sealing was achieved through a plug (with a sponge pad) provided by the lower windshield trim panel, but this structure resulted in water leakage due to a loose seal in the lower windshield trim panel. Summary of the Invention

[0004] The purpose of this invention is to solve the water leakage problem caused by the poor sealing of the lower windshield trim panel in the prior art, and to provide a structure for a washing system with an enlarged filling port and an automobile.

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] The present invention proposes a structure for enlarging the filling port of a washing system, including a lower front windshield trim panel and a guide pipe tank cap;

[0007] The lower front windshield trim panel is installed at the filling port of the hatch washing system. The guide tube tank cover is installed below the lower front windshield trim panel. The lower front windshield trim panel is provided with an elliptical plug with a smooth upper surface. One end of the guide tube tank cover is cylindrical, and the other end is a boss with a buckle.

[0008] Preferably, the boss structure is composed of several elongated arc protrusions, and an undercut is provided between adjacent elongated arc protrusions.

[0009] Preferably, the elongated arc convex structure and the inverted buckle are spaced at equal intervals.

[0010] Preferably, the boss structure consists of three elongated circular arc convex structures.

[0011] Preferably, the cylindrical structure comprises three cylindrical shells and two cylindrical tubes;

[0012] A cylindrical shell is connected to a cylindrical tube.

[0013] Preferably, the diameter of the cylindrical shell is much larger than the diameter of the cylindrical tube.

[0014] Preferably, the diameter of the spherical shell is much smaller than the diameter of the boss structure.

[0015] Preferably, the elliptical structure has dimensions of 40mm x 38mm.

[0016] Preferably, the boss structure is resilient.

[0017] A type of automobile that incorporates a washing system to enlarge the filling port.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention proposes a structure for enlarging the filling port of a washing system. The lower windshield trim panel is installed at the filling port of the hood washing system, and an oval-shaped plug is mounted on the lower windshield trim panel. This eliminates the need for a filter in the washing system and adds a guide tube cap, which provides a seal and solves the sealing problem. Specifically, one end of the guide tube cap is cylindrical, and the other end is a boss structure with a buckle. This unique structural design, combined with the oval-shaped plug on the lower windshield trim panel and its smooth upper surface, eliminates the need for a sponge pad on the plug, ensuring a seal during operation. The buckle engages with the filling port, reducing the force-bearing area and preventing the driver from needing excessive force to remove the cap. Therefore, the structure for enlarging the filling port of the washing system proposed in this invention solves the problems existing in the prior art.

[0020] Furthermore, the equal spacing between the elongated arc convex structure and the inverted buckle is to increase the stability of the boss structure.

[0021] Furthermore, the boss structure is tough and can absorb 6mm of interference.

[0022] Furthermore, the elongated arc convex structure is divided into three parts, and the contact surface with the filling port reduces the force-bearing area, thus avoiding the need for the car owner to use excessive force to pull off the cap. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings:

[0035] This invention proposes a structure for enlarging the filling port of a washing system, such as... Figures 1 to 3 As shown, it includes the lower front windshield trim panel 1 and the deflector cap 2;

[0036] The lower windshield trim panel 1 is installed at the filler port of the hatch washing system. The guide tube cap 7 is installed below the lower windshield trim panel 1. The lower windshield trim panel 1 has an elliptical plug with a smooth upper surface. One end of the guide tube cap 2 is a cylindrical structure 3, and the other end is a boss structure 4 with a buckle 5 on the boss structure 4. By installing the lower windshield trim panel 1 at the filler port of the hatch washing system and installing the plug on the lower windshield trim panel 1, the filter screen of the washing system is eliminated, and the guide tube cap 2 is added to seal the washing system, thus solving the sealing problem. Specifically, one end of the guide tube cap 2 is a cylindrical structure 3, and the other end is a boss structure 4. An inverted buckle 5 is provided on the boss structure 4. Through this unique structural design, combined with an elliptical plug on the lower windshield trim panel 1 with a smooth upper surface, the sponge pad on the plug is eliminated, enabling the washing system to provide a sealing effect during operation. Therefore, the enlarged filling port structure of the washing system proposed in this invention solves the problems existing in the prior art.

[0037] The boss structure 4 is composed of several elongated arc protrusions 6, with a retainer 5 between each adjacent elongated arc protrusion 6. The elongated arc protrusions 6 reduce the contact area, and the retainers 5 provide a locking mechanism. The equal spacing between the elongated arc protrusions 6 and the retainers 5 increases the stability of the boss structure 4. Preferably, the boss structure 4 consists of three elongated arc protrusions 6. The boss structure 4 is tough and can absorb 6mm of interference.

[0038] The cylindrical structure 3 includes three cylindrical shells 7 and two cylindrical tubes 8, with one cylindrical shell 7 connected to one cylindrical tube 8. The diameter of the cylindrical shell 7 is much larger than the diameter of the cylindrical tube 8, and the diameter of the cylindrical shell 7 is much smaller than the diameter of the boss structure 4. The dimensions of the elliptical structure are 40mm x 38mm.

[0039] This invention proposes a structure for an enlarged filling port in a washing system. Addressing the issue of a filling port size of only φ29mm, the structure has been adjusted multiple times and is now enlarged to 40mm x 38mm. This also simultaneously resolves the leakage problem caused by the loose seal of the cap provided with the lower windshield trim panel. The original filling port design of the washing system has been modified: the center position of the washing tank lid has been moved -35mm in the Y direction and -19mm in the X direction; the filling port cap has been changed from a φ29mm circle to a 40mm x 38mm ellipse, and the sponge pad on the cap has been removed; the washing system has eliminated the filter screen and added a guide tube and two caps for sealing. The filling port cap structure utilizes a guide tube flared structure for snap-fit ​​installation.

[0040] Therefore, the structure of the washing system with enlarged filling port proposed in this invention can effectively increase the size of the washing system filling port within the limited space of the vehicle; by adding the guide pipe tank cap 2, the problem of water leakage caused by the poor sealing of the plug provided by the front windshield lower trim panel 1 is solved.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
