Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to the external water-cutting structure of a vehicle door and the vehicle itself. Background Technology

[0002] To ensure the airtightness between the retractable windows and the doors, exterior door weatherstripping is required. As an important decorative and sealing component on car doors, exterior door weatherstripping not only serves to waterproof, dustproof, and reduce noise, but also effectively improves the overall appearance of the car and enhances its quality.

[0003] Traditional automotive door exterior water deflectors are typically installed using rivets or screws. These deflectors are usually stamped or extruded parts, which have complex manufacturing processes, require high labor intensity for workers, and screw fixing is time-consuming and labor-intensive.

[0004] To address these issues, a snap-fit ​​structure is installed on the door panel to directly fix the exterior waterstop to the panel. However, the exterior waterstop is almost entirely exposed outside the door, creating a step difference with the door panel and resulting in poor aesthetics.

[0005] Therefore, there is an urgent need for an external water-cutting structure for car doors and a vehicle to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an external water-cutting structure for car doors, which eliminates the step difference between the external water-cutting and the car door sheet metal, resulting in good aesthetics. Furthermore, only the end of the external water-cutting is exposed relative to the car door sheet metal, providing good concealment.

[0007] To address the aforementioned problems in the existing technology, this utility model adopts the following technical solution:

[0040] like Figure 1As shown, in this embodiment, the outer water-cutting structure of the car door includes an outer water-cutting body 1, a positioning boss 2, and a snap-fit ​​component. The outer water-cutting body 1 has a U-shaped structure and includes a head 11, a support portion 12, a connecting portion 13, and a pillar portion 14 connected in sequence. The head 11 abuts against the edge of the car door sheet metal 100, and the end face of the head 11 is flush with the outer end face of the car door sheet metal 100. The connecting portion 13 has a mounting hole. The positioning boss 2 is located on one side of the support portion 12 and abuts against the inner end face of the car door sheet metal 100. The snap-fit ​​component includes a fixed end cap 3 and a limiting buckle 4. The limiting buckle 4 is connected to the fixed end cap 3, passes through the mounting hole, and snaps against the car door sheet metal 100. The fixed end cap 3 abuts against the connecting portion 13.

[0041] For example, an external water-cutting structure is provided between the door sheet metal 100 and the glass 200. The external water-cutting structure serves to seal the glass 200, provide waterproofing and dustproofing, and match the appearance.

[0042] The end head 11 is connected to one end of the support part 12 and can abut against the edge of the door sheet metal 100. One end of the connecting part 13 is connected to the other end of the support part 12, and the connecting part 13 and the support part 12 form an L-shaped structure. The pillar part 14 is connected to the other end of the connecting part 13, and the pillar part 14 and the connecting part 13 form an L-shaped structure, which together form a U-shaped outer water-cutting body 1.

[0043] The positioning boss 2 is located between the door sheet metal 100 and the support part 12, and the positioning boss 2 protrudes from one side end face of the support part 12. The positioning boss 2 serves as a positioning reference and is used to position the support part 12 relative to the door sheet metal 100. That is, under the action of the positioning boss 2, the end face of the outer water cutter body 11 is flush with the outer end of the door sheet metal 100, eliminating the step difference between the outer water cutter and the door sheet metal 100, resulting in good aesthetics.

[0044] The limiting buckle 4 is made of elastic material. The connecting part 13 has an installation hole, and the reinforcing plate of the door sheet metal 100 has a connection hole. The limiting buckle 4 passes through the connection hole of the connecting part 13 and is engaged in the connection hole of the door sheet metal 100. At the same time, the fixing end cap 3 abuts against the end face of the connecting part 13, so that the outer water cutter body 1 is fixedly installed on the door sheet metal 100 under the action of the buckling member. The installation is firm and has a certain degree of concealment.

[0045] The external water-cutting structure of the car door is fixedly installed on the door sheet metal 100 via snap-fit ​​components. The support part 12, the connecting part 13, and the pillar part 14 are hidden in the gap between the door sheet metal 100 and the glass 200, with only the end head 11 exposed relative to the door sheet metal 100, making the external water-cutting structure semi-concealed and improving the user experience. Furthermore, under the action of the positioning boss 2, the end face of the end head 11 is flush with the outer end of the door sheet metal 100, eliminating the step difference between the external water-cutting structure and the door sheet metal 100, resulting in good aesthetics.

[0046] Furthermore, referring to Figure 1 The limiting buckle 4 includes a first contraction part 41 and a second contraction part 42 connected to the first contraction part 41. The first contraction part 41 is connected to the fixed end cover 3. Both the first contraction part 41 and the second contraction part 42 are elastic structures. The second contraction part 42 passes through the mounting hole and extends into the cavity of the door sheet metal 100. The first contraction part 41 can abut against the side wall of the door sheet metal 100.

[0047] The first contraction portion 41 and the second contraction portion 42 are set at an angle. During the process of the limiting buckle 4 passing through the mounting hole of the connecting portion 13 and the connecting hole of the door sheet metal 100, the connecting portion 13 between the first contraction portion 41 and the second contraction portion 42 is subjected to the squeezing action of the mounting hole and the connecting hole. The included angle between the first contraction portion 41 and the second contraction portion 42 gradually increases, that is, the limiting buckle 4 contracts inward. Until the connecting portion 13 between the first contraction portion 41 and the second contraction portion 42 completely passes through the connecting hole, the included angle between the first contraction portion 41 and the second contraction portion 42 instantly decreases, that is, the limiting buckle 4 expands outward and returns to its initial state, allowing the first contraction portion 41 to abut against the door sheet metal 100. At the same time, the fixed end cap 3 abuts against the connecting portion 13. Under the bidirectional limiting action of the first contraction portion 41 and the fixed end cap 3, the outer water-cutting body 1 is ensured to be firmly fixed relative to the door sheet metal 100, preventing it from shaking and thus reducing the noise generated by door vibration.

[0048] Furthermore, referring to Figure 1 The external water cutter body 1 also includes a limiting part 15, which is disposed on the connecting part 13, and a guide opening 5 is provided between the limiting part 15 and the column part 14. The guide opening 5 is used to guide the snap-fit ​​component into the mounting hole.

[0049] The limiting part 15 is close to the mounting hole and protrudes from the connecting part 13. There is a guide opening 5 between the limiting part 15 and the column. The guide opening 5 is connected to the mounting hole and has a guiding function, which can guide the snap-fit ​​part to smoothly enter the connecting hole, ensuring smooth and efficient installation of the snap-fit ​​part.

[0050] Furthermore, referring to Figure 1 Both the support part 12 and the connecting part 13 are hollow structures.

[0051] The support part 12 and the connecting part 13 are hollow structures, which reduces the overall weight of the outer water-cutting body 1 and can reduce production costs. Furthermore, in extremely cold or hot weather conditions, due to thermal expansion and contraction, the hollow structure can prevent the outer water-cutting body 1 from being squeezed, deformed, or cracked, thus extending the service life of the outer water-cutting body 1.

[0052] Furthermore, referring to Figure 1 The external water-cutting structure of the car door also includes a protrusion 6, which is disposed on the connecting part 13 and can abut against the car door sheet metal 100. There are multiple protrusions 6, which are distributed in a matrix on the connecting part 13.

[0053] With the help of multiple protrusions 6, the connecting part 13 is spaced apart from the door sheet metal 100 rather than in direct contact. That is, there is an installation gap between the connecting part 13 and the door sheet metal 100, which avoids the connecting part 13 from being deformed and damaged due to excessive snap-fitting of the snap-fit ​​parts. At the same time, the protrusions 6 can support the connecting part 13 relative to the door sheet metal 100, reduce stress concentration, and ensure the structural strength of the outer water-cutting structure.

[0054] Furthermore, referring to Figure 1 The positioning boss 2 and the support part 12 are integrally formed.

[0055] The positioning boss 2 and the support part 12 are integrally formed by casting or other methods, which reduces the risk of breakage of the positioning boss 2 relative to the support part 12, extends the service life of the positioning boss 2, and reduces replacement and maintenance costs. Preferably, the end head 11, support part 12, connecting part 13 and column part 14 connected in sequence are integrally formed, which has high structural strength, uses mold casting, is simple to process and form, and has relatively low manufacturing cost.

[0056] Furthermore, referring to Figure 1 The exterior water-cutting structure of the car door also includes a lip sealing strip 7 and a flocked layer 8. The lip sealing strip 7 is located on the other side of the support part 12 and abuts against the glass 200. The flocked layer 8 is located on the lip sealing strip 7. During the raising and lowering of the glass 200, the lip sealing strip 7 always abuts against the end face of the glass 200, providing a certain sealing effect. The flocked layer 8 covers the lip sealing strip 7 and directly seals against the glass 200, protecting the glass 200 and preventing irreversible scratches caused by the lip sealing strip 7 to the glass 200 during the raising and lowering of the glass 200.

[0057] This embodiment also provides a vehicle, including a door and the aforementioned external water-cutting structure, which is disposed on the door. The external water-cutting structure is fixedly installed on the door via snap-fit ​​components. The support portion 12, connecting portion 13, and pillar portion 14 are hidden within the gap of the door, with only the end head 11 exposed relative to the door, making the external water-cutting structure semi-concealed and improving the user experience. Furthermore, under the action of the positioning boss 2, the end face of the end head 11 is flush with the outer end of the door, eliminating the step difference between the external water-cutting structure and the door, resulting in good aesthetics.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
