[0033] Secondly, embodiments of this application provide a vehicle door, including the aforementioned external water-cutting assembly.

[0034] Thirdly, embodiments of this application provide a vehicle, including the aforementioned door.

[0035] According to the external water-cutting assembly, door, and vehicle provided in this application, the external water-cutting assembly is applied to a vehicle and installed on the door. The external water-cutting assembly includes an external water-cutting body and a first sealing lip and a second sealing lip connected to the external water-cutting body. The external water-cutting body is connected to the door sheet metal. The first and second sealing lips are located on the side of the external water-cutting body facing the interior space, i.e., the side facing the window glass. When the external water-cutting body is connected to the door sheet metal, due to the arrangement of the external water-cutting body and the window glass, the first sealing lip is in a bent state. Based on its elastic recovery force after deformation, the first sealing lip abuts against the door glass on its side facing the door glass to seal the gap between the external water-cutting body and the window glass. The second sealing lip operates similarly, also in a bent state. Because both the first and second sealing lips are bent between the external water-cutting body and the window glass, it is difficult to effectively support the window glass, resulting in significant swaying and noise during operation. To reduce noise between the external windshield washer assembly and the vehicle window glass, the external windshield washer assembly also includes a first support member. The first support member protrudes from the side of the first body portion opposite to the second body portion and is located between the first sealing lip and the second sealing lip. During bending, the first sealing lip can abut against at least a portion of the structure of the first support member. The first support member provides support to the first sealing lip in its bent state, thereby improving the stability of the first sealing lip in the bent state, reducing the swaying amplitude of the vehicle window glass, and decreasing the degree of noise from the vehicle window glass.

[0055] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0056] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0057] The external water-cutting component on the vehicle is installed on the outer edge of the door, on the side of the door away from the interior space, and is used to cut off water droplets, water mist and dust from the surface of the window glass when the window glass is raised or lowered relative to the door.

[0058] In actual operation, when the window glass deviates from the outside space, the outer bevel assembly can provide some support to maintain its relative position. However, when the outer bevel assembly contacts the window glass for support, it often produces abnormal noises. Furthermore, abnormal noises can also easily occur between the outer bevel assembly and the window glass during door opening and closing.

[0059] In view of this, firstly, please refer to Figures 1 to 4 This application provides an external water-cutting assembly 100 for a vehicle door 200. The external water-cutting assembly 100 includes an external water-cutting body 10, a first sealing lip 20, a first support member 30, and a second sealing lip 40. The external water-cutting body 10 includes a first body portion 11 and a second body portion 12 bent and connected, the first body portion 11 and the second body portion 12 forming a clamping groove C, and the external water-cutting body 10 is connected to the vehicle door 200 through the clamping groove C. The first sealing lip 20 protrudes from the side of the first body portion 11 opposite to the second body portion 12; the first support member 30 protrudes from the side of the first body portion 11 opposite to the second body portion 12; and the second sealing lip 40 protrudes from the side of the first body portion 11 opposite to the second body portion 12. The first support member 30 is located between the first sealing lip 20 and the second sealing lip 40, and the first sealing lip 20 can abut against at least a portion of the structure of the first support member 30 during bending.

[0060] The external water-cutting component 100 provided in this application embodiment is applied to a vehicle and installed on a door 200. The door 200 includes a door sheet metal 201, which has a window opening 202. A window glass 203 is provided at the window opening 202. The external water-cutting component 100 is installed on the door sheet metal 201 at the window sill stop position of the window opening 202 and is located on the side of the window glass 203 away from the interior space.

[0061] Specifically, the external water-cutting assembly 100 includes an external water-cutting body 10 and a first sealing lip 20 and a second sealing lip 40 connected to the external water-cutting body 10. The external water-cutting body 10 is connected to the door sheet metal 201. The first sealing lip 20 and the second sealing lip 40 are located on the side of the external water-cutting body 10 facing the interior space, that is, the side facing the window glass 203. The first sealing lip 20 and the second sealing lip 40 can contact the window glass 203. When the window glass 203 rises or falls relative to the door sheet metal 201, it cuts off impurities on the surface of the window glass 203.

[0062] The outer water-cutting body 10 includes a first body portion 11 and a second body portion 12 that are bent and connected. The first body portion 11 and the second body portion 12 form a clamping groove C, which has a U-shaped structure. The outer water-cutting body 10 is connected to the door sheet metal 201 through the clamping groove C. When the outer water-cutting body 10 is installed on the door sheet metal 201, one of the first body portion 11 and the second body portion 12 is located inside the door sheet metal 201, and the other is located outside the door sheet metal 201. In this embodiment, for ease of description, it is taken that the first body portion 11 is located inside the door sheet metal 201 and the second body portion 12 is located outside the door sheet metal 201 to clearly describe the structure of the outer water-cutting assembly 100. Optionally, when the outer water-cutting body 10 is installed on the door sheet metal 201, the dimension of the first body portion 11 in the longitudinal direction of the door 200 can be larger than the dimension of the second body portion 12 in the longitudinal direction of the door 200, or the dimension of the second body portion 12 in the longitudinal direction of the door 200 can be larger than the dimension of the first body portion 11 in the longitudinal direction of the door 200. This is not limited in the embodiments of this application. Considering that the second body portion 12 is located outside the door sheet metal 201, it is preferable to set the dimension of the second body portion 12 in the longitudinal direction of the door 200 to be smaller than the dimension of the first body portion 11 in the longitudinal direction of the door 200, so as to improve the aesthetics of the outer water-cutting assembly 100 installed on the door sheet metal 201.

[0063] The window glass 203 is located on the side of the first body part 11 away from the second body part 12. The first sealing lip 20 protrudes from the side of the first body part 11 away from the second body part 12, and the second sealing lip 40 protrudes from the side of the first body part 11 away from the second body part 12. That is to say, both the first sealing lip 20 and the second sealing lip 40 are located on the side of the outer water-cutting body 10 facing the window glass 203. When the outer water-cutting body 10 is connected to the door sheet metal 201, the outer water-cutting body 10, the first sealing lip 20, and the second sealing lip 40 are fixed in position relative to the door sheet metal 201. Generally, the distance between the outer water-cutting body 10 and the window glass 203 is less than the extension length of the first sealing lip 20. Due to the setting of the outer water-cutting body 10 and the window glass 203, the first sealing lip 20 is in a bent state. Based on its elastic recovery force after deformation, the first sealing lip 20 abuts against the door glass on the side facing the door glass 200 to seal the gap between the outer water-cutting body 10 and the window glass 203. Similarly, the distance between the outer water-cutting body 10 and the window glass 203 is also less than the extension length of the second sealing lip 40. The second sealing lip 40 is also in a bent state. The second sealing lip 40 also abuts against the door glass 200 on the side facing the door glass 200 based on its elastic recovery force after deformation, so as to seal the gap between the outer water-cutting body 10 and the window glass 203. When the window glass 203 rises or falls relative to the door sheet metal 201, the side of the first sealing lip 20 and the second sealing lip 40 facing the window glass 203 is always abutting against the window glass 203 to cut off impurities on the surface of the window glass 203.

[0064] During vehicle operation, the window glass 203 inevitably shakes. When the window glass 203 shakes, it may shake outwards, towards the side closer to the outer waterstop body 10, which will compress the first sealing lip 20 and the second sealing lip 40. Since both the first sealing lip 20 and the second sealing lip 40 are bent between the outer waterstop body 10 and the window glass 203, they cannot effectively support the window glass 203, resulting in a large amplitude of shaking and significant abnormal noise. Simultaneously, the window glass 203 also shakes during the opening and closing of the door 200, which, based on the above analysis, also produces significant abnormal noise. Figure 3 In the diagram, the positional relationship between the first sealing lip 20 and the second sealing lip 40 during the bending process is shown by dashed lines.

[0065] To reduce noise between the external water-cutting assembly 100 and the vehicle window glass 203, the external water-cutting assembly 100 provided in this application embodiment further includes a first support member 30. The first support member 30 protrudes from the side of the first body portion 11 opposite to the second body portion 12 and is located between the first sealing lip 20 and the second sealing lip 40. The first sealing lip 20 can abut against at least a portion of the structure of the first support member 30 during bending. The first support member 30 is also located on the side of the external water-cutting body 10 facing the vehicle window glass 203. When the first sealing lip 20 is in a bent state, the first sealing lip 20 can abut against at least a portion of the structure of the first support member 30, and the first support member 30 can provide a certain degree of support for the first sealing lip 20 in the bent state, thereby improving the stability of the first sealing lip 20 in the bent state.

[0066] During the shaking of the window glass 203, since the first sealing lip 20 and at least part of the structure of the first support member 30 are in contact, when the window glass 203 exerts a compressive force on the first sealing lip 20, the first sealing lip 20 can transmit the compressive force to the first support member 30. Subsequently, the first support member 30 generates a certain degree of reaction force to support the first sealing lip 20 and the window glass 203, thereby reducing the shaking amplitude of the window glass 203 and reducing the degree of abnormal noise of the window glass 203.

[0067] In summary, in this embodiment, the external water-cutting assembly 100 is applied to a vehicle and installed on the door 200. The external water-cutting assembly 100 includes an external water-cutting body 10 and a first sealing lip 20 and a second sealing lip 40 connected to the external water-cutting body 10. The external water-cutting body 10 is connected to the door sheet metal 201. The first sealing lip 20 and the second sealing lip 40 are located on the side of the external water-cutting body 10 facing the interior space, that is, the side facing the window glass 203. When the external water-cutting body 10 is connected to the door sheet metal 201, due to the arrangement of the external water-cutting body 10 and the window glass 203, the first sealing lip 20 is in a bent state. Based on its elastic recovery force after deformation, the side of the first sealing lip 20 facing the door glass abuts against the door glass 200 to seal the gap between the external water-cutting body 10 and the window glass 203. The second sealing lip 40 is also in a bent state. Because both the first sealing lip 20 and the second sealing lip 40 are bent between the outer water-cutting body 10 and the window glass 203, they are unable to effectively support the window glass 203. As a result, the window glass 203 experiences significant swaying during movement, generating considerable noise. To reduce the noise between the outer water-cutting assembly 100 and the window glass 203, the outer water-cutting assembly 100 also includes a first support member 30. The first support member 30 protrudes from the side of the first body portion 11 opposite to the second body portion 12 and is located between the first sealing lip 20 and the second sealing lip 40. During bending, the first sealing lip 20 can abut against at least a portion of the structure of the first support member 30. The first support member 30 provides some support to the bent first sealing lip 20, improving its stability and thus reducing the swaying amplitude of the window glass 203 and the noise level.

[0068] In some embodiments, please refer to Figures 1 to 4 The clamping groove C has an open end D1 and a closed end D2 disposed opposite to each other along the first direction X. The first support member 30 extends along the first direction X toward the side closer to the closed end D2, and the first sealing lip 20 extends along the first direction X toward the side closer to the closed end D2. The extension length of the first support member 30 is less than the extension length of the first sealing lip 20. An inclined portion 31 is provided on the side of the first support member 30 facing the first sealing lip 20. The inclined portion 31 is disposed at the end of the first support member 30 away from the first body portion 11, and the distance between the inclined portion 31 and the first sealing lip 20 gradually increases along the side away from the first body portion 11.

[0069] The clamping groove C has a U-shaped structure and has an open end D1 and a closed end D2 arranged opposite to each other in the first direction X. When the outer water-cutting body 10 is installed on the door 200 and applied to the vehicle, the first direction X is consistent with the height direction of the vehicle. The window glass 203 also rises or falls along the height direction of the vehicle. The first sealing lip 20 is inclined in the first direction X and extends along the first direction X toward the side closer to the closed end D2. When the outer water-cutting body 10 is installed on the door 200 and applied to the vehicle, the end of the first sealing lip 20 away from the outer water-cutting body 10 is higher in the height direction than the end of the first sealing lip 20 near the outer water-cutting body 10, so as to form a good sealing effect between the outer water-cutting body 10 and the window glass 203.

[0070] To enhance the supporting effect of the first support member 30 on the first sealing lip 20, the first support member 30 is positioned on the side of the first sealing lip 20 facing the closed end D2. The first support member 30 is also inclined in the first direction X, extending along the first direction X towards the side closer to the closed end D2. By inclining the first support member 30 and the first sealing lip 20 on the same side of the first direction X, the first support member 30 can directly contact the first sealing lip 20 during bending. Simultaneously, the force exerted by the first support member 30 on the first sealing lip 20 is directed towards the side of the first sealing lip 20 away from the window glass 203, thus supporting the first sealing lip 20 while minimizing damage to it.

[0071] In this embodiment, the first support member 30 is mainly used to support the first sealing lip 20. To improve the supporting capacity of the first support member 30, its extension length is set to a relatively short form. Compared to a relatively long extension length, this provides better strength and rigidity, thus improving the supporting capacity of the first support member 30. To avoid affecting the interaction between the first sealing lip 20 and the window glass 203, the extension length of the first support member 30 is set to be less than the extension of the first sealing lip 20. That is, the end of the first support member 30 away from the outer water-cutting body 10 is located on the side of the first sealing lip 20 away from the outer water-cutting body 10, opposite to the window glass 203. When the window glass 203 shakes, it will cause the first sealing lip 20 to bend further. During the further bending of the first sealing lip 20, the first support member 30 can contact the first sealing lip 20 to reduce the bending amplitude of the first sealing lip 20, thereby reducing the shaking amplitude of the window glass 203 and reducing the abnormal noise of the window glass 203.

[0072] Considering that the first sealing lip 20 is inclined in the first direction X, and that the first sealing lip 20 comes into contact with the first support member 30 during the process of tilting and bending, an inclined portion 31 is provided on the side of the first support member 30 facing the first sealing lip 20. The inclined portion 31 is provided at the end of the first support member 30 away from the first body portion 11, and the distance between the inclined portion 31 and the first sealing lip 20 gradually increases on the side away from the first body portion 11. Since the first sealing lip 20 is inclined in the first direction X, and the first support member 30 is also inclined in the first direction X, in order to facilitate good support between the first support member 30 and the first sealing lip 20, the first support member 30 forms an inclined support surface at the inclined portion 31, so that the inclined portion 31 can form a planar support with the first sealing lip 20 on the support surface. While improving the support effect of the first support member 30 on the first sealing lip 20, compared with the end point support between the first support member 30 and the first sealing lip 20, the end surface support between the first support member 30 and the first sealing lip 20 can also reduce the damage of the first support member 30 to the first sealing lip 20, so as to extend the service life of the first sealing lip 20.

[0073] In some embodiments, please refer to Figures 1 to 4 The first support member 30 has a first protective layer on the side facing the first sealing lip 20, and the wear resistance of the first protective layer is higher than that of the first support member 30. And / or, the first sealing lip 20 has a second protective layer on the side facing the first support member 30, and the wear resistance of the second protective layer is higher than that of the first sealing lip 20.

[0074] During the shaking of the vehicle window glass 203, the first support member 30 supports the first sealing lip 20. The side of the first support member 30 facing the first sealing lip 20 frequently comes into contact with or separates from the side of the first sealing lip 20 facing the first support member 30, resulting in a certain degree of friction. To reduce wear between the first support member 30 and the first sealing lip 20, a first protective layer is provided on the side of the first support member 30 facing the first sealing lip 20. The wear resistance of the first protective layer is higher than that of the first support member 30. During contact between the first support member 30 and the first sealing lip 20, the first support member 30 contacts and supports the first sealing lip 20 through the first protective layer. A second protective layer is provided on the side of the first sealing lip 20 facing the first support member 30. The wear resistance of the second protective layer is higher than that of the first sealing lip 20. During contact between the first sealing lip 20 and the first support member 30, the first sealing lip 20 contacts the first support member 30 through the second protective layer. Optionally, the first protective layer and the second protective layer can be made of the same material.

[0075] In some embodiments, please refer to Figures 1 to 4 A third protective layer 21 is provided on the side of the first sealing lip 20 away from the first support member 30, and the surface roughness of the third protective layer 21 is less than that of the first sealing lip 20.

[0076] During the raising or lowering of the window glass 203, the first sealing lip 20 and the window glass 203 are always in contact. The window glass 203 also rises and falls relative to the first sealing lip 20, resulting in sliding friction between them, which may cause some abnormal noise. To reduce the abnormal noise caused by sliding friction, a third protective layer 21 is provided on the side of the first sealing lip 20 away from the first support member 30. The first sealing lip 20 contacts the window glass 203 through the third protective layer 21. The surface roughness of the third protective layer 21 is less than that of the first sealing lip 20, thereby reducing the degree of sliding friction when the first sealing lip 20 contacts the window glass 203. This reduces abnormal noise and also reduces damage to the window glass 203 caused by the first sealing lip 20. For example, the third protective layer 21 includes a flocked layer.

[0077] In some embodiments, please refer to Figures 1 to 4 The clamping groove C has an open end D1 and a closed end D2 disposed opposite to each other along the first direction X, and the first sealing lip 20 extends along the first direction X toward the side closer to the closed end D2. The third protective layer 21 includes a first protective part 211 and a second protective part 212 connected to each other. At least a portion of the first protective part 211 is disposed on the side covering the first sealing lip 20 away from the first support member 30, and at least a portion of the second protective part 212 is disposed covering the end of the first sealing lip 20 away from the first body part 11.

[0078] Considering that the window glass 203 has both rising and falling movements relative to the first sealing lip 20, when the window glass 203 rises relative to the first sealing lip 20, the window glass 203 mainly slides and rubs against the side of the first sealing lip 20 away from the first support member 30. When the window glass 203 falls relative to the first sealing lip 20, the window glass 203 mainly slides and rubs against the end of the first sealing lip 20 away from the first body part 11.

[0079] To enable the third protective layer 21 to provide targeted protection, the first protective layer includes a first protective portion 211 and a second protective portion 212 connected to each other. At least a portion of the first protective portion 211 is located on the side of the first sealing lip 20 facing away from the first support member 30, and at least a portion of the second protective portion 212 covers the end of the first sealing lip 20 away from the first body portion 11. When the window glass 203 rises relative to the first sealing lip 20, the window glass 203 mainly experiences sliding friction with the first protective portion 211. When the window glass 203 falls relative to the first sealing lip 20, the window glass 203 mainly experiences sliding friction with the second protective portion 212. Since the surface roughness of the third protective layer 21 is less than that of the first sealing lip 20, the contact between the third protective layer 21 and the window glass 203 can reduce the friction intensity of the window glass 203 compared to the contact between the first sealing lip 20 and the window glass 203, reduce the friction noise generated by the window glass 203 during the rising and falling process, and also reduce the wear of the window glass 203.

[0080] In some embodiments, please refer to Figures 1 to 4 The clamping groove C has an open end D1 and a closed end D2 disposed opposite to each other along the first direction X, and the second sealing lip 40 extends along the first direction X toward the side closer to the closed end D2. The distance between the connection position between the second sealing lip 40 and the first body part 11 and the connection position between the first sealing lip 20 and the first body part 11 is greater than the extension dimension of the first sealing lip 20.

[0081] To improve the sealing effect of the second sealing lip 40 between the outer waterstop body 10 and the window glass 203, the second sealing lip 40 is inclined in the first direction X, and extends along the first direction X towards the side closer to the closed end D2. When the outer waterstop body 10 is installed on the door 200 and applied to the vehicle, the end of the second sealing lip 40 away from the outer waterstop body 10 is higher in the height direction than the end of the second sealing lip 40 closer to the outer waterstop body 10, so as to form a good sealing effect between the outer waterstop body 10 and the window glass 203.

[0082] The first sealing lip 20, the first support member 30, and the second sealing lip 40 are inclined in the same direction in the first direction X. In order to reduce the mutual influence between the first sealing lip 20 and the second sealing lip 40 and to avoid the first sealing lip 20 from contacting the second sealing lip 40 during bending, the distance between the connection position between the second sealing lip 40 and the first body part 11 and the connection position between the first sealing lip 20 and the first body part 11 is set to be greater than the extension dimension of the first sealing lip 20. Even if the first sealing lip 20 is bent to fit against the first body part 11, there is still a gap between the first sealing lip 20 and the second sealing lip 40, thereby reducing the mutual influence between the first sealing lip 20 and the second sealing lip 40 and ensuring the relative independence between the first sealing lip 20 and the second sealing lip 40.

[0083] In some embodiments, please refer to Figures 1 to 4 The external water-cutting assembly 100 also includes a sealing lip 50, which is disposed on the side of the first body portion 11 opposite to the second body portion 12 and connected to the closed end D2. The distance between the end of the sealing lip 50 away from the first body portion 11 and the connection position between the second sealing lip 40 and the first body portion 11 is greater than the distance between the end of the second sealing lip 40 away from the first body portion 11 and the connection position between the second sealing lip 40 and the first body portion 11.

[0084] When the second sealing lip 40 is inclined along the first direction X, there may be a situation where part of the structure of the second sealing lip 40 extends beyond the outer water-cutting body 10, and part of the structure of the second sealing lip 40 can be seen from the outside of the vehicle door 200. In order to improve the aesthetics of the outer water-cutting assembly 100 and to form a certain support structure on the side of the second sealing lip 40 away from the vehicle window glass 203, the outer water-cutting assembly 100 provided in this application embodiment also includes a sealing lip 50. The sealing lip 50 is disposed on the side of the first body portion 11 away from the second body portion 12 and connected to the closed end D2. The sealing lip 50 is located on the side of the second sealing lip 40 away from the first sealing lip 20.

[0085] During the raising or lowering of the window glass 203, the second sealing lip 40 bends to a certain extent. During the bending of the second sealing lip 40, the distance between the end of the second sealing lip 40 away from the first body part 11 and the first body part 11 changes. In order to ensure the supporting effect of the sealing lip 50 on the second sealing lip 40, the distance between the end of the sealing lip 50 away from the first body part 11 and the connection position between the second sealing lip 40 and the first body part 11 is set to be greater than the distance between the end of the second sealing lip 40 away from the first body part 11 and the connection position between the second sealing lip 40 and the first body part 11, so that the end of the second sealing lip 40 away from the first body part 11 does not exceed the sealing lip 50 in the first direction X, and the end of the second sealing lip 40 away from the first body part 11 is always within the extension range of the sealing lip 50 in the first direction X.

[0086] In some embodiments, please refer to Figures 1 to 4 The second sealing lip 40 includes a first lip 41 and a second lip 42 that are bent and connected. The first lip 41 is connected to the first body portion 11, and the second lip 42 is connected to the end of the first lip 41 that is away from the first body portion 11. The second lip 42 is located on the side of the first lip 41 that is away from the first support member 30, and the distance between the end of the second lip 42 away from the first lip 41 and the first body portion 11 is smaller than the distance between the end of the first lip 41 away from the first body portion 11 and the first body portion 11.

[0087] To facilitate contact and support between the second sealing lip 40 and the enclosing lip 50 during bending, the second sealing lip 40 includes a first lip 41 and a second lip 42 that are bent and connected. During the raising and lowering of the window glass 203, the first lip 41 mainly contacts the window glass 203, and the second lip 42 mainly contacts the enclosing lip 50 to support the first lip 41.

[0088] The second lip 42 bends from the end of the first lip 41 away from the first body 11 toward the side opposite to the window glass 203 and toward the side closer to the first body 11. The distance between the end of the second lip 42 away from the first lip 41 and the first body 11 is smaller than the distance between the end of the first lip 41 away from the first body 11 and the first body 11. By bending the second lip 42, the sealing contact between the first lip 41 and the window glass 203 is not affected, and support is formed between the first lip 41 and the encapsulation part, thereby improving the sealing effect of the first lip 41 between the outer water-cutting body 10 and the window glass 203.

[0089] In some embodiments, please refer to Figures 1 to 4A fourth protective layer 51 is provided on the side of the sealing lip 50 facing the second sealing lip 40, and the wear resistance of the fourth protective layer 51 is higher than that of the sealing lip 50. And / or, a fifth protective layer is provided on the side of the second lip 42 facing the sealing lip 50, and the wear resistance of the fifth protective layer is higher than that of the second lip 42.

[0090] During the raising and lowering of the window glass 203, the second lip 42 and the sealing lip 50 frequently come into contact or disengage, resulting in a certain degree of friction. To reduce wear between the second lip 42 and the sealing lip 50, a fourth protective layer 51 is provided on the side of the sealing lip 50 facing the second sealing lip 40. The fourth protective layer 51 has higher wear resistance than the sealing lip 50. During contact between the sealing lip 50 and the second lip 42, the sealing lip 50 contacts and is supported by the fourth protective layer 51. A fifth protective layer is provided on the side of the second lip 42 facing the sealing lip 50. The fifth protective layer has higher wear resistance than the second lip 42. During contact between the second lip 42 and the sealing lip 50, the second lip 42 contacts the sealing lip 50 through the fifth protective layer. Optionally, the fourth protective layer 51 and the fifth protective layer can be made of the same material, and the first protective layer, the second protective layer, the fourth protective layer 51 and the fifth protective layer can be made of the same material.

[0091] In some embodiments, please refer to Figures 1 to 4 A sixth protective layer 43 is provided on the side of the second sealing lip 40 away from the sealing lip 50, and the surface roughness of the sixth protective layer 43 is less than that of the second sealing lip 40.

[0092] During the raising or lowering of the window glass 203, the second sealing lip 40 and the window glass 203 are always in contact. The window glass 203 also rises and falls relative to the second sealing lip 40, resulting in sliding friction between them, which may cause some abnormal noise. To reduce the abnormal noise caused by sliding friction, a sixth protective layer 43 is provided on the side of the second sealing lip 40 away from the sealing lip 50. The second sealing lip 40 contacts the window glass 203 through the sixth protective layer 43. The surface roughness of the sixth protective layer 43 is less than that of the second sealing lip 40, thereby reducing the degree of sliding friction when the second sealing lip 40 contacts the window glass 203. This reduces abnormal noise and also reduces damage to the window glass 203 caused by the second sealing lip 40. For example, the sixth protective layer 43 includes a flocked layer.

[0093] In some embodiments, please refer to Figures 1 to 4The sixth protective layer 43 includes a third protective part 431 and a fourth protective part 432 that are connected to each other. At least a portion of the third protective part 431 covers the side of the second sealing lip 40 away from the sealing lip 50, and at least a portion of the fourth protective part 432 covers the end of the second sealing lip 40 away from the first body part 11.

[0094] Considering that the window glass 203 has both rising and falling movements relative to the second sealing lip 40, when the window glass 203 rises relative to the second sealing lip 40, the window glass 203 mainly slides and rubs against the side of the second sealing lip 40 away from the sealing lip 50, and when the window glass 203 falls relative to the second sealing lip 40, the window glass 203 mainly slides and rubs against the end of the second sealing lip 40 away from the first body part 11.

[0095] To enable the sixth protective layer 43 to provide targeted protection, it includes a third protective portion 431 and a fourth protective portion 432 connected opposite to each other. At least a portion of the third protective portion 431 is located on the side of the second sealing lip 40 facing away from the sealing lip 50, and at least a portion of the fourth protective portion 432 covers the end of the second sealing lip 40 away from the first body portion 11. When the window glass 203 rises relative to the second sealing lip 40, the window glass 203 mainly experiences sliding friction with the third protective portion 431. When the window glass 203 falls relative to the second sealing lip 40, the window glass 203 mainly experiences sliding friction with the fourth protective portion 432. Since the surface roughness of the sixth protective layer 43 is less than that of the second sealing lip 40, the contact between the sixth protective layer 43 and the window glass 203 can reduce the friction intensity of the window glass 203 compared to the contact between the second sealing lip 40 and the window glass 203, reduce the friction noise generated by the window glass 203 during the rising and falling process, and also reduce the wear of the window glass 203.

[0096] In some embodiments, please refer to Figures 1 to 4 The sealing lip 50 includes a first sealing portion 52 and a second sealing portion 53 connected to each other. The first sealing portion 52 is connected to the first body portion 11 and protrudes from the first body portion 11 along a first direction X. The second sealing portion 53 is connected to the first sealing portion 52 and protrudes from the first body portion 11 along a second direction Y, where the second direction Y intersects the first direction X. The second sealing portion 53 extends along the side away from the closing end D2 in the first direction X.

[0097] The sealing lip 50 can enclose the second sealing lip 40 in the first direction X to improve the aesthetics of the external water-cutting assembly 100. The sealing lip 50 includes a first sealing portion 52 and a second sealing portion 53 connected to each other. In order to ensure that the sealing lip 50 can reliably enclose the second sealing lip 40 in the first direction X, the first sealing portion 52 protrudes from the first body portion 11 in the first direction X, and the end of the first sealing portion 52 away from the first body portion 11 in the first direction X is higher than the end of the second sealing lip 40 away from the first body portion 11 in the first direction X.

[0098] When the outer water-cutting body 10 is installed on the door 200 and applied to the vehicle, the first direction X is consistent with the height direction of the vehicle, and the second direction Y is consistent with the width direction of the vehicle. There is a gap between the first enclosing part 52 and the window glass 203 in the second direction Y. To reduce the probability of debris from the external environment entering the second sealing lip 40 through this gap, the sealing lip 50 also includes a second enclosing part 53. The second enclosing part 53 protrudes from the first body part 11 in the second direction Y, facing the window glass 203, to partially block the gap between the first enclosing part 52 and the window glass 203 in the second direction Y. This reduces the opening size of the gap between the first enclosing part 52 and the window glass 203 in the second direction Y, further reducing the probability of debris from the external environment entering the second sealing lip 40 through this gap.

[0099] In some embodiments, please refer to Figures 4 to 6 The external water-cutting assembly 100 includes a bright strip structure 60, which is connected to the side of the external water-cutting body 10 away from the clamping groove C. The bright strip structure 60 is located on the side of the first body portion 11 away from the first sealing lip 20.

[0100] The outer water-cutting assembly 100 is installed on the outer side of the door sheet metal 201. To improve the aesthetics of the outer water-cutting assembly 100, it also includes a bright strip structure 60. The bright strip structure 60 is connected to the side of the outer water-cutting body 10 away from the clamping groove C and is located on the side of the first body portion 11 away from the first sealing lip 20. When the outer water-cutting assembly 100 is installed on the door 200, the bright strip structure 60 is located outside the door 200 and covers the first body portion 11, thereby improving the aesthetics of the outer water-cutting assembly 100.

[0101] In some embodiments, the two ends of the bright strip structure 60 are connected to the outer water-cutting body 10 along the first direction X, and a portion of the bright strip structure 60 is spaced apart from the second body portion 12. A second support member 61 is provided on the side of the second body portion 12 away from the first body portion 11 and / or on the side of the bright strip structure 60 facing the second body portion 12, and the second support member 61 is supported between the second body portion 12 and the bright strip structure 60.

[0102] When the outer water-cutting body 10 is connected to the door sheet metal 201, the first body part 11 is inside, the second body part 12 is outside, and the two ends of the bright strip structure 60 in the first direction X are connected to the outer water-cutting body 10 and cover the second body part 12. Optionally, a groove structure can be formed on the outer water-cutting body 10 so that the two structures can be engaged with the outer water-cutting body 10 through the groove structure.

[0103] When the bright strip structure 60 is connected to the outer water-cutting body 10, a portion of the bright strip structure 60 is spaced apart from the second body portion 12. To ensure the fullness of the bright strip structure 60 and reduce the probability of the bright strip structure 60 denting, a second support member 61 is provided on the side of the second body portion 12 away from the first body portion 11 and / or on the side of the bright strip structure 60 facing the second body portion 12. The second support member 61 is supported between the second body portion 12 and the bright strip structure 60 to ensure that the second body portion 12 and the bright strip structure 60 have a specific distance, thereby reducing the probability of the bright strip structure 60 denting towards the second body portion 12.

[0104] In some embodiments, please refer to Figures 4 to 6 The two ends of the bright strip structure 60 along the first direction X are connected to the outer water-cutting body 10, and a portion of the bright strip structure 60 is spaced apart from the second body part 12. A reinforcing strip 62 is also provided on the side of the bright strip structure 60 facing the second body part 12. The reinforcing strip 62 extends along the third direction Z, and the third direction Z, the second direction Y, and the first direction X intersect each other.

[0105] To enhance the structural strength of the bright strip structure 60, a reinforcing strip 62 is provided on the side of the bright strip structure 60 facing the second body part 12, extending along the third direction Z. When the outer water-cutting assembly 100 is installed in the door 200 and applied to the vehicle, the first direction X aligns with the height direction of the vehicle, the second direction Y aligns with the width direction of the vehicle, and the third direction Z aligns with the length direction of the vehicle. Since the window opening 202 has a certain extension dimension in the length direction of the vehicle, the window glass 203 also has a certain extension dimension in the length direction of the vehicle, and the outer water-cutting body 10, the first sealing lip 20, the first support 30, the second sealing lip 40, and the bright strip structure 60 also have certain extension dimensions in the length direction of the vehicle. The reinforcing strip 62 extends along the third direction Z, that is, along the length direction of the vehicle, and can reinforce the bright strip structure 60 at multiple locations in the third direction Z, thereby increasing the strength of the bright strip structure 60 at multiple locations in the third direction Z and reducing the probability of the bright strip structure 60 denting.

[0106] When the outer water-cutting body 10 extends along the third direction Z, the outer water-cutting body 10 includes a first part and a second part connected along the third direction Z. A first sealing lip 20 extends along the first part, and a first support member 30 extends along the first part. That is, the extension dimensions of the first sealing lip 20 and the first support member 30 along the third direction Z are smaller than the extension dimensions of the outer water-cutting body 10 along the third direction Z. When the outer water-cutting assembly 100 is applied to a vehicle, the third direction Z is consistent with the length direction of the vehicle, and the first sealing lip 20 and the first support member 30 may not be provided near the B-pillar of the vehicle.

[0107] In some embodiments, please refer to Figures 4 to 6 The outer water-cutting body 10 also includes a skeleton structure 13, which is embedded inside the outer water-cutting body 10. The skeleton structure 13 can ensure the strength of the clamping groove C formed by the outer water-cutting body 10, and can improve the installation stability of the outer water-cutting body 10 on the door sheet metal 201 when the outer water-cutting body 10 is installed on the door sheet metal 201.

[0108] In some embodiments, a first protrusion 14 protrudes from the first body portion 11 toward the second body portion 12, and a plurality of first protrusions 14 are provided, the plurality of first protrusions 14 being spaced apart along a first direction X. And / or, a second protrusion 15 protrudes from the second body portion 12 toward the first body portion 11, and a plurality of second protrusions 15 are provided, the plurality of second protrusions 15 being spaced apart along a first direction X.

[0109] To improve the clamping stability of the outer water-cutting body 10 on the door sheet metal 201, a first protrusion 14 can be provided on the side of the first body portion 11 facing the second body portion 12, thereby increasing the roughness of the side of the first body portion 11 facing the door sheet metal 201. Furthermore, a second protrusion 15 can be provided on the side of the second body portion 12 facing the first body portion 11, thereby increasing the roughness of the side of the second body portion 12 facing the door sheet metal 201. Through the interaction of the first protrusion 14 and the second protrusion 15, the clamping stability of the outer water-cutting body 10 on the door sheet metal 201 can be improved.

[0110] Secondly, please refer to Figures 1 to 3 This application provides a vehicle door 200, including the external water-cutting component 100 provided in any embodiment of the first aspect of this application. The vehicle door 200 includes a door sheet metal 201, with a window opening 202. A window glass 203 is provided at the window opening 202. The external water-cutting component 100 is mounted on the door sheet metal 201 at the window sill stop of the window opening 202, and is located on the side of the window glass 203 facing away from the interior space. This vehicle door 200 includes all the technical features and effects of the aforementioned external water-cutting component 100, which will not be elaborated further here.

[0111] Thirdly, embodiments of this application provide a vehicle including the door 200 provided in the second aspect of this application. This vehicle includes all the technical features and effects of the aforementioned door 200, which will not be elaborated further here.

[0112] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
