[0029] The external water cutter assembly 100 includes a door panel 1, a water cutter body 2, an exterior trim panel 3, and a water cutter end cap 4.

[0030] The door panel 1 includes an inner panel 11 and an outer panel 12. A mounting groove 1a is defined between the inner panel 11 and the outer panel 12 along a third direction. The inner panel 11 has a mounting opening 1b. The mounting groove 1a is positioned facing the opening of the window glass 300. The water-cutting body 2 can be placed within the mounting groove 1a, with a portion extending through the opening to contact the window glass 300. This effectively seals the gap between the window glass 300 and the door panel 1, i.e., the opening, achieving functions such as wiping water and removing dust. The first overlapping end 2a of the water-cutting body 2... The second overlapping end 3a of the exterior trim panel 3 is set at the mounting opening 1b and overlaps with the first overlapping end 2a through the opening in the mounting groove 1a. Then, the water-cutting end cap 4 of the independent part is detachably connected to the door panel 1 and / or the exterior trim panel 3 to cover the mounting opening 1b, which can improve the installation efficiency. The water-cutting end cap 4 includes a cover body 41 and a snap-fit ​​assembly 42. The snap-fit ​​is set on the cover body 41. The cover body 41 is used to cover the mounting opening 1b, and the snap-fit ​​assembly 42 is used to snap-fit ​​with the door panel 1 and / or the exterior trim panel 3.

[0031] The cover 41 includes a first connecting plate 411 and a second connecting plate 412. One end of the second connecting plate 412 is connected to the first connecting plate 411, and the other end of the second connecting plate 412 is bent towards the door panel 1 along a second direction. The snap-fit ​​assembly 42 includes a first snap-fit ​​member 421 and a second snap-fit ​​member 422. The first snap-fit ​​member 421 is disposed on the first connecting plate 411 and is used to snap-fit ​​with the exterior trim panel 3. The second snap-fit ​​member 422 is disposed on the second connecting plate 412 and is used to snap-fit ​​with the door panel 1. In this way, not only can the gap between the water-cut end cover 4 at the installation opening 1b and the door panel 1 and the exterior trim panel 3 be reduced, but the connection strength between the water-cut end cover 4, the exterior trim panel 3 and the door panel 1 can also be improved.

[0032] One of the first snap-fit ​​component 421 and the outer trim panel 3 has a slot 3b, and one of the first snap-fit ​​component 421 and the outer trim panel 3 has a buckle 421a. The buckle 421a engages with the slot 3b. This not only improves installation efficiency but also reduces the possibility of the water cutter end cap 4 becoming loose or falling off during use.

[0033] The slot 3b has an insertion interface 3b1. A limiting rib 3b2 is formed on the slot wall surface along the third direction inside the slot 3b. A step portion 421b is formed on the surface of the buckle 421a along the third direction. The buckle 421a enters or exits the slot 3b through the insertion interface 3b1. When the buckle 421a is located in the slot 3b, the step portion 421b abuts against the surface of the limiting rib 3b2 facing the buckle 421a. In this way, the connection stability between the water-cut end cap 4 and the outer trim panel 3 can be further improved.

[0034] One of the second snap-fit ​​member 422 and the door panel 1 has a snap-fit ​​opening 11a, and the other of the second snap-fit ​​member 422 and the door panel 1 has a snap-fit ​​post 422a. A flange 422b is formed on the peripheral side of the snap-fit ​​post 422a. When the snap-fit ​​post 422a is located in the snap-fit ​​opening 11a, the flange 422b abuts against the periphery of the snap-fit ​​opening 11a facing the snap-fit ​​post 422a. In this way, the connection stability between the water-cut end cap 4 and the door panel 1 can be further improved.

[0035] The snap-fit ​​assembly 42 includes a pin 423, which is disposed on the cover 41 and located between the first snap-fit ​​member 421 and the second snap-fit ​​member 422 along the first direction. The first overlapping end 2a has a socket 2b, which is connected to the mounting port 1b. The pin 423 is used to engage with the socket 2b. In this way, the water cutter end cover 4 can be prevented from tilting or deflecting to a certain extent, thereby improving the overall connection stability of the water cutter end cover 4.

[0036] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0037] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. The terms "first," "second," etc., used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] To better understand the external water-cutting assembly 100 provided in this application, the vehicle 1000 will be described first.

[0039] One embodiment of this application provides a vehicle 1000, please refer to... Figure 1 This includes the external water-cutting assembly 100 in any of the following embodiments.

[0040] Vehicle 1000 can be a gasoline vehicle, a hybrid vehicle, a range-extended vehicle, or a pure electric vehicle, etc.

[0041] The external water-cutting assembly 100 can be installed at the front door and / or rear door of the vehicle 1000.

[0042] Another embodiment of this application discloses an external water-cutting assembly 100, please refer to... Figures 2 to 6 The external water-cutting assembly 100 includes a door panel 1, a water-cutting body 2, an exterior trim panel 3, and a water-cutting end cap 4. The door panel 1 is disposed on one side of the window glass 300 along a first direction. The door panel 1 has a mounting groove 1a and a mounting opening 1b communicating with the mounting groove 1a, with the mounting groove 1a opening towards the window glass 300. The water-cutting body 2 is disposed in the mounting groove 1a, with a portion of the water-cutting body 2 extending through the opening and contacting the window glass 300. One end of the water-cutting body 2 is a first overlapping end 2a, located at the mounting opening 1b. The exterior trim panel 3 is disposed on one side of the window glass 300 along a second direction. One end of the exterior trim panel 3 is a second overlapping end 3a, which is disposed in the mounting groove 1a through an opening and overlaps with the water-cutting body 2. The water-cutting end cap 4 is detachably connected to the door panel 1 and / or the exterior trim panel 3 to cover the mounting opening 1b, wherein the first direction and the second direction intersect.

[0043] For example, the first direction can be the vertical direction of the vehicle 1000, where up refers to the direction of the roof and down is the opposite of up. The second direction can be the length direction of the vehicle 1000, and the third direction can be the width direction of the vehicle 1000.

[0044] The external water-cutting assembly 100 provided in this application has a door panel 1 placed on one side of the window glass 300 along a first direction. The door panel 1 has a mounting groove 1a and a mounting opening 1b communicating with the mounting groove 1a. The mounting groove 1a is set facing the opening of the window glass 300. The water-cutting body 2 can be placed in the mounting groove 1a, and part of it protrudes through the opening to contact the window glass 300. In this way, the gap between the window glass 300 and the door panel 1, i.e. the opening, can be effectively sealed, realizing functions such as wiping water and removing dust. By placing the water-cutting body 2 in the mounting groove 1a, not only can the water-cutting body 2 be protected, but it can also be hidden to a certain extent, making the overall appearance more aesthetically pleasing. By setting the first overlapping end 2a of the water-cutting body 2 at the mounting opening 1b, and setting the second overlapping end 3a of the exterior trim panel 3 through an opening in the mounting groove 1a and overlapping with the first overlapping end 2a, and then detachably connecting the independent water-cutting end cap 4 to the door panel 1 and / or the exterior trim panel 3 to cover the mounting opening 1b, on the one hand, the problem of interference between the exterior trim panel 3 and the water-cutting end cap 4 during assembly, making installation difficult, can be effectively solved, making it convenient for operators to install; on the other hand, the water-cutting end cap 4 adopts a detachable connection method, making the disassembly and installation of the water-cutting end cap 4 simpler and more efficient; furthermore, the detachable connection between the water-cutting end cap 4 and the door panel 1 and / or the exterior trim panel 3 can improve the connection strength between the water-cutting end cap 4 and the door panel 1 and / or the exterior trim panel 3, resulting in good working stability.

[0045] The vehicle 1000 provided in this application embodiment has good working stability and ease of installation based on the advantages of the aforementioned installation structure of the interior and exterior trim panels 3.

[0046] It should be noted that the installation of the concealed external water cutter needs to be carried out before the installation of the outer trim panel 3. However, the structural nature of the integrated water cutter end cap 4 and water cutter body 2 makes it difficult to flexibly change the installation position, and eventually it will cause structural interference with the outer trim panel 3 above it. Especially when it is paired with the European-style top strip 200, the outer trim panel 3 will move downward, making it even more difficult to install. In this application, the water cutter end cap 4 and water cutter body 2 are both independent components, which can be flexibly installed according to the needs to avoid the outer trim panel 3, making the installation more convenient.

[0047] In one exemplary embodiment, Figure 2 In this context, R1 can be the first direction, and R2 can be the second direction. Figure 6 R3 in this context can be a third party.

[0048] As an example, in one embodiment, please refer to Figure 1 The exterior trim panel 3 can be installed on the B-pillar or C-pillar, and the mounting port 1b is located at the end of the door panel 1 along the second direction near the rear door.

[0049] For example, in one embodiment, the exterior trim panel 3 includes a panel body and an envelope. The panel body extends along a first direction and is disposed on one side of the vehicle window glass 300. The envelope covers the outer surface of the panel body to protect and shield the panel body. The end of the envelope along the first direction near the water-cutting body 2 is a second overlapping panel.

[0050] In one embodiment, please refer to Figures 3 to 5 The water cutter end cap 4 includes a cap body 41 and a snap-fit ​​assembly 42. The snap-fit ​​assembly is disposed on the cap body 41. The cap body 41 is used to cover the installation port 1b. The snap-fit ​​assembly 42 is used to snap-fit ​​with the door panel 1 and / or the exterior trim panel 3.

[0051] For example, the snap-fit ​​component 42 may be disposed within the cover 41.

[0052] Here, the cover 41 is used to cover the installation opening 1b, which can reduce the entry of dust, moisture, etc. into the door panel 1, and improve the sealing performance and aesthetics of the external water cutter assembly 100. The snap-fit ​​assembly 42 is used to snap into the door panel 1 and / or the exterior trim panel 3. On the one hand, compared with fasteners or welding, the snap-fit ​​does not require additional tools and equipment, which can reduce the difficulty and cost of installation and disassembly; on the other hand, the snap-fit ​​can make the water cutter end cover 4 and the door panel 1 and / or the exterior trim panel 3 form a stable integral structure, which can enhance the connection strength between the water cutter end cover 4 and the door panel 1 and / or the exterior trim panel 3, and improve the stability of the entire door structure.

[0053] In one embodiment, please refer to Figures 3 to 5 The cover 41 includes a first connecting plate 411 and a second connecting plate 412. One end of the second connecting plate 412 is connected to the first connecting plate 411, and the other end of the second connecting plate 412 is bent towards the door panel 1 along a second direction. The snap-fit ​​assembly 42 includes a first snap-fit ​​member 421 and a second snap-fit ​​member 422. The first snap-fit ​​member 421 is disposed on the first connecting plate 411 and is used to snap-fit ​​with the exterior trim panel 3. The second snap-fit ​​member 422 is disposed on the second connecting plate 412 and is used to snap-fit ​​with the door panel 1.

[0054] For example, the first connecting plate 411 can extend generally along a first direction, one end of the second connecting plate 412 is connected to the first connecting plate 411, and the other end of the second connecting plate 412 can be bent along a second direction toward the door panel 1, so that the angle between the first connecting plate 411 and the second connecting plate 412 is approximately an obtuse angle. The first snap-fit ​​member 421 can be disposed at the end of the first connecting plate 411 away from the second connecting plate 412 along the first direction, and the first snap-fit ​​member 421 can extend in a vertical direction. The second snap-fit ​​member 422 can be disposed on the surface of the second connecting plate 412 facing the door panel 1.

[0055] Here, the first connecting plate 411 and the second connecting plate 412 are connected at an angle, which can better adapt to the positional relationship between the water-cutting end cap 4, the exterior trim panel 3, and the door panel 1, thereby reducing structural interference between the water-cutting end cap 4 and the exterior trim panel 3 and the door panel 1. By setting the first snap-fit ​​member 421 and the second snap-fit ​​member 422, the first snap-fit ​​member 421 is engaged with the exterior trim panel 3, and the second snap-fit ​​member 422 is engaged with the door panel 1. On the one hand, the first connecting plate 411 and the second connecting plate 412 can better cover the mounting opening 1b, reducing the gap between the water-cutting end cap 4 and the door panel 1 and the exterior trim panel 3 at the mounting opening 1b, thus enhancing the aesthetic effect and sealing performance. On the other hand, it can improve the connection strength between the water-cutting end cap 4, the exterior trim panel 3, and the door panel 1, reducing the possibility of the water-cutting end cap 4 falling off due to shaking, and ensuring good working stability.

[0056] In one embodiment, please refer to Figure 6 One of the first snap-fit ​​member 421 and the outer trim panel 3 has a slot 3b, and one of the first snap-fit ​​member 421 and the outer trim panel 3 has a buckle 421a, which engages with the slot 3b.

[0057] For example, a slot 3b can be formed at the second overlapping end 3a, and a buckle 421 can be formed on the first snap-fit ​​member 421, which engages with the slot 3b.

[0058] Here, the water cutter end cap 4 and the outer trim panel 3 are connected by a combination of a buckle 421a and a slot 3b. On the one hand, during installation, the buckle 421a can be aligned with the slot 3b and inserted to complete the connection, which is highly efficient. On the other hand, it has high strength and stability, and can withstand a certain amount of external force and vibration, reducing the possibility of the water cutter end cap 4 loosening or falling off during use. Furthermore, it can conceal the connection part 421a1 between the two, making the overall appearance more aesthetically pleasing.

[0059] In one embodiment, please refer to Figure 6 The slot 3b has an insertion interface 3b1. A limiting rib 3b2 is formed on the slot wall surface along the third direction inside the slot 3b. A step portion 421b is formed on the surface of the buckle 421a along the third direction. The buckle 421a enters or exits the slot 3b through the insertion interface 3b1. When the buckle 421a is located in the slot 3b, the step portion 421b abuts against the surface of the limiting rib 3b2 facing the buckle 421a. The first direction, the second direction and the third direction intersect each other.

[0060] For example, taking the first snap fastener 421 having a snap fastener 421a and the outer trim panel 3 having a snap groove 3b as an example, the snap groove 3b has an insertion interface 3b1 formed along the first direction toward the groove wall of the first snap fastener 421, and the groove wall surfaces on both sides of the snap groove 3b along the third direction can be formed with limiting ribs 3b2, and a notch is formed between the two limiting ribs 3b2. The buckle 421a includes a connecting portion 421a1, a first elastic arm 421a2, and a second elastic arm 421a3. One end of the first elastic arm 421a2 and one end of the second elastic arm 421a3 are respectively disposed in the connecting portion 421a1 along a third direction. The other end of the first elastic arm 421a2 and the other end of the second elastic arm 421a3 are offset away from the connecting plate along a third direction, so that the width of the buckle 421a gradually decreases along the direction close to the first connecting plate 411 and away from the first connecting plate 411, so that the buckle 421a is approximately "arrow" shaped. The step portion 421b is formed at the offset ends of the first elastic arm 421a2 and the second elastic arm 421a3.

[0061] Here, when installing the water-cut end cap 4 onto the outer trim panel 3, the buckle 421a can be inserted into the slot 3b through the insertion interface 3b1. During insertion, since the width of the buckle 421a gradually decreases along the direction close to the first connecting plate 411 and away from the first connecting plate 411, the buckle 421a forms guide surfaces on both sides along the third direction, which facilitates the insertion of the buckle 421a. When the buckle 421a is in the slot 3b, the step portion 421b will abut against the surface of the limiting rib 3b2 facing the buckle 421a. In this way, the contact surface between the buckle 421a and the slot 3b can be increased to further improve the connection stability between the water-cut end cap 4 and the outer trim panel 3.

[0062] In some other embodiments, taking the first snap-fit ​​member 421 having a snap-fit ​​groove 3b and the outer trim panel 3 having a snap-fit ​​421a as an example, the snap-fit ​​groove 3b has an insertion interface 3b1 formed along the groove wall of the first snap-fit ​​member 421 in the first direction, and the groove wall surfaces on both sides of the snap-fit ​​groove 3b along the third direction can be formed with limiting ribs 3b2, and a notch is formed between the two limiting ribs 3b2. The buckle 421a includes a connecting portion 421a1, a first elastic arm 421a2, and a second elastic arm 421a3. One end of the first elastic arm 421a2 and one end of the second elastic arm 421a3 are respectively disposed in the connecting portion 421a1 along a third direction. The other end of the first elastic arm 421a2 and the other end of the second elastic arm 421a3 are offset away from the connecting plate along a third direction, so that the width of the buckle 421a gradually increases along the direction close to the first snap-fit ​​member 421 and away from the first snap-fit ​​member 421, so that the buckle 421a is approximately "arrow" shaped. The step portion 421b is formed at the offset ends of the first elastic arm 421a2 and the second elastic arm 421a3.

[0063] As an example, in one embodiment, please refer to Figure 2 and Figure 3 The door panel 1 includes an inner panel 11 and an outer panel 12. The inner panel 11 and the outer panel 12 are separated by a mounting groove 1a in a third direction. The inner panel 11 has a mounting opening 1b.

[0064] In one embodiment, please refer to Figures 3 to 5 One of the second latching member 422 and the door panel 1 has a latching opening 11a, and the other of the second latching member 422 and the door panel 1 has a latching post 422a. A flange 422b is formed on the peripheral side of the latching post 422a. When the latching post 422a is located in the latching opening 11a, the flange 422b abuts against the periphery of the latching opening 11a facing the latching post 422a.

[0065] For example, a snap-fit ​​11a may be formed on the inner plate 11, which may communicate with the mounting groove 1a. The second snap-fit ​​member 422 may be formed with a snap-fit ​​post 422a, which includes a first half-post 422a1 and a second half-post 422a2. The first half-post 422a1 and the second half-post 422a2 are spaced apart to form a compression groove. The peripheral surfaces of the first half-post 422a1 and the second half-post 422a2 form flanges 422b, so that the diameter of the snap-fit ​​post 422a gradually decreases in the direction from the second connecting plate 412 away from the second connecting plate 412.

[0066] Here, when installing the water-cutting end cap 4 on the door panel 1, the snap-fit ​​post 422a can be inserted into the bayonet 11a. During insertion, since the diameter of the snap-fit ​​post 422a gradually decreases along the direction from the second connecting plate 412 away from the second connecting plate 412, the flange 422b on the peripheral side of the snap-fit ​​post 422a forms a guide surface, which facilitates the insertion of the snap-fit ​​post 422a. When the snap-fit ​​post 422a is located in the bayonet 11a, the flange 422b will abut against the periphery of the bayonet 11a facing the snap-fit ​​post 422a. In this way, the contact surface between the snap-fit ​​post 422a and the bayonet 11a can be increased, thereby further improving the connection stability between the water-cutting end cap 4 and the door panel 1.

[0067] In other embodiments, a snap-fit ​​post 422a may be formed on the inner plate 11, and a snap-fit ​​member 422 may be formed with a snap-fit ​​opening 11a. The snap-fit ​​post 422a includes a first half-post 422a1 and a second half-post 422a2. The first half-post 422a1 and the second half-post 422a2 are spaced apart to form a compression groove. The peripheral surfaces of the first half-post 422a1 and the second half-post 422a2 form flanges 422b, such that the diameter of the snap-fit ​​post 422a gradually decreases along the direction from the snap-fit ​​opening 11a away from the snap-fit ​​opening 11a.

[0068] In one embodiment, please refer to Figures 3 to 5The snap-fit ​​assembly 42 includes a pin 423, which is disposed on the cover 41 and located between the first snap-fit ​​member 421 and the second snap-fit ​​member 422 along the first direction. The first overlapping end 2a has a socket 2b, which is connected to the mounting port 1b. The pin 423 is used to engage with the socket 2b.

[0069] For example, the pin 423 may be disposed on the first connecting plate 411 and between the first latch 421 and the second latch 422 along a first direction.

[0070] In this way, by setting an insertion port 2b at the first overlapping end 2a, and setting a pin 423 between the first snap fastener 421 and the second snap fastener 422 along the first direction, the cover 41 can be inserted and connected in the middle of the water-cutting end cover 4, which can prevent the water-cutting end cover 4 from tilting or deflecting to a certain extent and improve the overall connection stability of the water-cutting end cover 4.

[0071] For example, in one embodiment, the plug-in plate may be integrally formed with the first snap-fit ​​member 421 and disposed within the first connecting plate 411.

[0072] In one embodiment, the cover 41 is made of TPV (thermoplastic vulcanizate). TPV is used as the material for the cover 41 because, on the one hand, TPV has good elasticity and resistance to compression deformation, allowing it to fit well with the door panel 1 and the exterior trim panel 3. For example, when installing the exterior trim panel 3, it can effectively absorb shock and cushion the impact. On the other hand, TPV has excellent aging resistance and environmental resistance, making it less prone to aging, cracking, and other phenomena, resulting in good operational stability.

[0073] In one embodiment, the second snap-fit ​​member 422 is made of TPV. For example, this facilitates connection with the sheet metal door panel 1 to achieve a good sealing fit with the snap-fit ​​11a.

[0074] In one embodiment, the pin 423 and the first snap-fit ​​component 421 are made of PA66 (polyamide 66) and GF35 (glass fiber reinforced with a content of 35%). On the one hand, PA66 and GF35 have high wear resistance, which enables the snap-fit ​​component 42 to resist wear and corrosion during long-term use and extend its service life; on the other hand, PA66 and GF35 are easy to process and mold, and can be easily made into snap-fit ​​components 42 of various shapes.

[0075] In one embodiment, the cover 41 and the snap-fit ​​assembly 42 are injection molded. On the one hand, a variety of plastic materials can be used to meet the different functional requirements of the cover 41 and the snap-fit ​​assembly 42; on the other hand, injection molding can produce parts with complex geometries, which allows the cover 41 and the snap-fit ​​assembly 42 to be designed into various complex shapes and structures to meet different assembly requirements.

[0076] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. All modifications, equivalent substitutions, improvements, etc., within the spirit and principles of this application are included within the scope of protection of this application.
