[0044] The present invention provides an external water-cutting component.

[0045] Reference Figures 1 to 9 In an embodiment of the present invention, the external water-cut assembly includes a vehicle door assembly 100, a mounting bracket 200 and an external water-cut assembly 300; the mounting bracket 200 is connected to the vehicle door assembly 100 and is located on the inner side of the end corner of the vehicle door assembly 100; the external water-cut assembly 300 includes an external water-cut corner 30 and an external water-cut insert 40, the external water-cut insert 40 is fixedly connected to the external water-cut corner 30, and is used to be fastened and fixed with the mounting bracket 200. In this arrangement, the external water-cut insert 40 is fastened and fixed with the mounting bracket 200, which provides an effective fixing point for the assembly of the external water-cut corner 30 while also improving the connection firmness between the external water-cut corner 30 and the vehicle door assembly 100, thereby improving the assembly stability and assembly efficiency of the external water-cut corner 30.

[0046] Specifically, the mounting bracket 200 can be fixedly connected to the vehicle door assembly 100 by spot welding, plugging, snapping, etc., ensuring that the mounting bracket 200 is firmly installed on the vehicle door assembly 100, while providing an installation and fixing point for the reliable assembly of the external water cutting angle 30, so that the external water cutting angle 30 can be quickly and firmly assembled on the mounting bracket 200 through the external water cutting insert 40, thereby realizing the reliable assembly of the external water cutting angle 30, and at the same time, it is beneficial to improve the assembly stability and assembly efficiency of the external water cutting angle 30.

[0047] Among them, the mounting bracket 200 is located on the inner side of the end corner of the door assembly 100. The end corner of the door assembly 100 specifically refers to the upper end of the door assembly 100 away from the hinged connection with the vehicle body. In this way, it can provide an installation and fixing point with the external water-cut corner 30 in the external water-cut assembly 300, facilitating the connection and fixation between the external water-cut corner 30 and the door assembly 100.

[0048] The mounting bracket 200 is located on the inner side of the door assembly 100, that is, the mounting bracket 200 is located on the side of the door assembly 100 facing the vehicle body, so that the outer water cut corner 30 can be in close contact with the vehicle body, thereby playing a sealing role and improving the sealing of the vehicle; and it can ensure that the outer water cut corner 30 is covered by the door assembly 100 to achieve a hidden setting, reducing the visible area of the outer water cut corner 30 and improving the viewing value of the vehicle.

[0049] The external water-cut corner 30 and the external water-cut insert 40 are an integral structure, and can be connected into a whole by means of concave-convex inlay, integrated molding, snap-on connection, etc. In this way, the external water-cut corner 30 can be supported by the external water-cut insert 40 to prevent excessive deformation of the external water-cut corner 30, and the external water-cut insert 40 is fastened to the mounting bracket 200 and can be connected by means of flip buckles, deformation buckles, etc., effectively preventing the external water-cut corner 30 from detaching from the mounting bracket 200 and causing sealing failure.

[0050] The technical solution of the present invention, by adopting the snap-fitting cooperation between the mounting bracket 200 and the outer watertight insert 40, not only provides an effective fixing point for the assembly of the outer watertight corner 30, but also improves the connection firmness between the outer watertight corner 30 and the vehicle door assembly 100, thereby improving the assembly stability and assembly efficiency of the outer watertight corner 30. Specifically, the outer watertight insert 40 is fixedly connected to the outer watertight corner 30, effectively preventing excessive deformation of the outer watertight corner 30 and ensuring that the outer watertight corner 30 is reliably assembled to the vehicle door assembly 100. The mounting bracket 200 is fixed to the inner side of the end corner of the vehicle door assembly 100, ensuring that the outer watertight corner 30 is assembled to the vehicle door assembly 100 through the installation cooperation between the outer watertight insert 40 and the mounting bracket 200. When the vehicle door assembly 100 is used, the outer watertight corner 30 is concealed and the vehicle is sealed, thereby improving the vehicle's appearance and sealing performance.

[0051] Reference Figures 4 to 7 In one embodiment, the external water-cut corner 30 includes a corner body 31 and a clamping portion 32 connected to one side of the corner body 31, the clamping portion 32 has a clamping groove 321 with an opening 442 facing downward, the external water-cut insert 40 is at least partially embedded in the groove wall of the clamping groove 321, the mounting bracket 200 is inserted into the clamping groove 321, and is buckled and fixed to the external water-cut insert 40. It can be understood that the external water-cut corner 30 can be inserted from top to bottom along the vehicle door assembly 100, and the top end of the mounting bracket 200 extends into the clamping groove 321, and then the external water-cut insert 40 can be buckled and fixed to the mounting bracket 200, thereby realizing full restriction of the degree of freedom of the external water-cut corner 30 to meet the reliable assembly of the external water-cut corner 30.

[0052] The setting of the clamping groove 321 can limit the effective assembly range of the mounting bracket 200, ensuring that the mounting bracket 200 can enter the clamping groove 321 during assembly, and then the mounting bracket 200 can be quickly buckled and fixed with the external water-cut insert 40, thereby improving the assembly efficiency of the external water-cut corner 30.

[0053] The external water-cut insert 40 is at least partially embedded in the groove wall of the clamping groove 321, and the groove wall can be a groove side wall or a groove bottom wall. By being partially embedded in the groove wall of the clamping groove 321, it is helpful to ensure that the external water-cut insert 40 is reliably connected to the clamping portion 32. At this time, the remaining part can be exposed from the groove wall of the clamping groove 321 to snap into the mounting bracket 200 extending into the clamping groove 321, thereby realizing reliable assembly of the external water-cut joint 30 and the vehicle door assembly 100.

[0054] Reference Figures 5 to 6 In one embodiment, the external water-cut insert 40 includes a first embedding portion 41 and a buckle portion 43 provided on the first embedding portion 41. The first embedding portion 41 is fixed to one side wall of the clamping groove 321, and the buckle portion 43 protrudes from the first embedding portion 41 and extends toward the other side wall of the clamping groove 321. The mounting bracket 200 is provided with a buckle hole 21 corresponding to the buckle portion 43. It can be understood that when the mounting bracket 200 moves toward the bottom wall of the clamping groove 321, the mounting bracket 200 is buckled and fixed with the protruding buckle portion 43 through its own buckle hole 21, and then cooperates with the specific structure of the clamping groove 321 to effectively limit the movement of the mounting bracket 200 in a direction perpendicular to the bottom wall of the groove and in a direction perpendicular to the side wall of the groove. In other words, the movement of the external water-cut corner 30 relative to the mounting bracket 200 is limited. In this way, the connection convenience and connection stability of the external water-cut insert 40 and the mounting bracket 200 can be improved, thereby improving the assembly efficiency and assembly reliability of the external water-cut corner 30.

[0055] The first embedding portion 41 and the clamping portion 32 are integrally formed and can be connected by embedding, bonding, or integrated molding. The buckle portion 43 is laterally connected to the first embedding portion 41 and can be directly fixedly connected to the first embedding portion 41 or connected via an adapter to facilitate the mutual fit and restriction between the buckle portion 43 and the buckle hole 21. However, in other embodiments, the buckle hole 21 can be provided in the first embedding portion 41, and the buckle portion 43 can be provided on the mounting bracket 200.

[0056] Specifically, in one embodiment, the first embedded portion 41 is provided with a through hole 411, and a connecting portion 42 is fixed to the hole wall of the through hole 411. The connecting portion 42 is arranged in parallel with the first embedded portion 41 and extends in a direction away from the mounting bracket 200. The buckle portion 43 is laterally connected to the connecting portion 42, so that when the external water cutting angle 30 is inserted into the mounting bracket 200 and the buckle portion 43 abuts against the mounting bracket 200, force continues to be applied to the external water cutting angle 30. At this time, the connecting portion 42 is deformed by the force, and the buckle portion 43 always abuts against the mounting bracket 200 and moves relative to the mounting bracket 200 until the buckle portion 43 is snapped into the buckle hole 21.

[0057] A plurality of through holes 411 can be provided along the extension direction of the corner body 31. At this time, each through hole 411 is provided with a connecting portion 42 connected to a buckle 43, and the mounting bracket 200 is provided with a through hole 411 corresponding to each buckle 43. In this way, the number of clamping points on the mounting bracket 200 can be increased, and at the same time, the external water-cut insert 40 can be effectively prevented from rotating relative to the mounting bracket 200, so that the connection firmness and connection stability between the external water-cut insert 40 and the mounting bracket 200 can be greatly improved.

[0058] The connecting portion 42 is arranged in parallel with the first embedded portion 41, so that the buckle portion 43 can be laterally connected to the connecting portion 42 and extend toward the other side wall of the clamping groove 321, and when inserted into the mounting bracket 200, it can play a guiding role so that the buckle portion 43 can be quickly and accurately inserted into the buckle hole 21, thereby improving the assembly efficiency of the outer water-cut insert 40 and the mounting bracket 200, and the connecting portion 42 extends in a direction away from the mounting bracket 200. It can be understood that the setting of the through hole 411 can not only lighten the outer water-cut insert 40, but also provide for the deformation of the connecting portion 42. An avoidance space is provided, wherein the through hole 411 includes a first hole wall and a second hole wall arranged opposite to each other, one end of the connecting portion 42 is connected to the first hole wall, and a gap is left between the other end and the second hole wall. In this arrangement, when the connecting portion 42 is subjected to force, it can bend and deform in the through hole 411 to allow the mounting bracket 200 to move in the clamping groove 321, and then when the buckle portion 43 is aligned with the buckle hole 21 of the mounting bracket 200, the connecting portion 42 will return to its original shape, and the buckle portion 43 will be inserted into the buckle hole 21, thereby achieving reliable clamping of the buckle portion 43 and the buckle hole 21.

[0059] More specifically, in one embodiment, the connecting portion 42 includes a guide section 421 and a stop section 422. The surface of the guide section 421 facing the other groove side wall of the clamping groove 321 is a guide arc surface 423. The buckle portion 43 is provided at the connection between the guide section 421 and the stop section 422. The surface of the buckle portion 43 facing the guide section 421 smoothly transitions to the guide arc surface 423. Such a setting can, on the one hand, play a guiding role. Through the setting of the guide arc surface 423, the mounting bracket 200 can move relative to the buckle portion 43 along the guide arc surface 423, which is conducive to quickly finding the buckle portion 43. The buckle 43 is positioned in the guide section 421, and the surface of the buckle 43 facing the guide section 421 is smoothly transitioned to the guide arc surface 423, which effectively prevents the mounting bracket 200 from being stuck at the connection between the buckle 43 and the guide section 421, which is beneficial to the rapid snap-fitting of the buckle hole 21 and the buckle 43, thereby accelerating the assembly efficiency. On the other hand, it can play a limiting role, and cooperate with the setting of the blocking section 422. When the buckle 43 and the buckle hole 21 are snapped together, the blocking section 422 abuts against the edge of the buckle hole 21, and the buckle 43 abuts against the hole wall of the buckle hole 21, thereby effectively limiting the movement of the external water cutting angle 30 relative to the mounting bracket 200.

[0060] Since the surface of the guide section 421 facing the other groove side wall of the clamping groove 321 is a guide arc surface 423, and the guide arc surface 423 protrudes in the direction away from the other groove side wall of the clamping groove 321, in order to avoid the risk of structural fracture caused by the guide section 421 being too thin, the surface of the guide section 421 away from the other groove side wall of the clamping groove 321 is protruding to play a thickening role.

[0061] Optionally, in one embodiment, a side wall of the clamping groove 321 is provided with an avoidance hole 322 corresponding to the through hole 411, and the avoidance hole 322 is used for the deformation of the connecting portion 42. This can provide an avoidance space so that the connecting portion 42 can be reliably deformed under the supporting action of the mounting bracket 200. At the same time, the manufacturing cost can be reduced without affecting the overall structure of the clamping portion 32.

[0062] Reference Figure 6 In one embodiment, the external water-cut insert 40 further includes a second embedding portion 44, which is bent and connected to the first embedding portion 41 and fixedly connected to the other side wall of the clamping groove 321. The mounting bracket 200 is located between the first embedding portion 41 and the second embedding portion 44. It can be understood that the external water-cut insert 40 is arranged along the groove wall of the clamping groove 321, which can increase the effective contact area, thereby enhancing the connection tightness between the external water-cut insert 40 and the clamping portion 32, and can further limit the mounting bracket 200 between the first embedding portion 41 and the second embedding portion 44, thereby preventing the mounting bracket 200 from acting on the clamping portion 32 to cause excessive deformation of the clamping portion 32, or the mounting bracket 200 from being separated from the clamping portion 32, which is beneficial to improving the assembly reliability of the external water-cut joint 30 and the mounting bracket 200.

[0063] The two opposing surfaces of the first embedding portion 41 and the second embedding portion 44 are gradually expanded in a direction away from the bottom wall of the clamping groove 321 to guide the mounting bracket 200 to extend between the first embedding portion 41 and the second embedding portion 44, thereby completing the snap fit between the buckle hole 21 of the mounting bracket 200 and the buckle portion 43.

[0064] Furthermore, in one embodiment, the second embedded portion 44 is provided with at least one through hole 441, the through hole 441 passes through the first embedded portion 41, and is arranged adjacent to the buckle portion 43, and the clamping portion 32 is provided with a connecting protrusion 323 adapted to the through hole 441. It can be understood that a plurality of buckles 43 can be provided, that is, a plurality of through holes 411 are provided, and they are staggered with the through holes 441. On the one hand, it is beneficial to increase the effective contact area between the external water-cut insert 40 and the clamping portion 32, thereby improving the connection firmness between the external water-cut insert 40 and the clamping portion 32; on the other hand, it is beneficial to uniformize the force and improve the connection stability of the external water-cut insert 40.

[0065] There can be multiple through holes 441 , and the multiple through holes 441 can be arranged in an array on the second embedding portion 44 , that is, they can be spaced apart along the length extension direction of the second embedding portion 44 and / or spaced apart along the width extension direction of the second embedding portion 44 .

[0066] Optionally, in one embodiment, the second embedding portion 44 is provided with an opening 442, and the opening 442 is arranged corresponding to the buckle portion 43, which can lighten the external water-cut insert 40. In addition, when the external water-cut insert 40 is manufactured using an integrated molding process, it is convenient to demold the external water-cut insert 40.

[0067] Reference Figures 3 to 4 、 Figure 8 In one embodiment, the mounting bracket 200 includes a fixing portion 22 and a supporting portion 23. The fixing portion 22 is fixedly connected to the vehicle door assembly 100. The supporting portion 23 is bent and connected to the fixing portion 22 and is provided with a buckle hole 21. It can be understood that the fixing portion 22 can be fixed to the vehicle door assembly 100 by connection methods such as spot welding and clamping, thereby providing an assembly fixing point on the vehicle door assembly 100 for the outer water cut corner 30; and the specific shape structure formed by the bending connection between the supporting portion 23 and the fixing portion 2231 is adapted to the shape structure of the vehicle door assembly 100, which is conducive to the support portion 23 being as close as possible to and spaced from the vehicle door assembly 100, facilitating the support portion 23 to be inserted between the first embedded portion 41 and the second embedded portion 44, and being fixed by the buckle hole 21 on the supporting portion 23 and the buckle 43 on the first embedded portion 41, thereby improving the assembly stability of the outer water cut corner 30 with the mounting bracket 200 and the vehicle door assembly 100.

[0068] Specifically, in one embodiment, the length of the support portion 23 in the extension direction of the external water-cut angle 30 is longer than that of the fixing portion 22. On the one hand, while ensuring the connection strength of the mounting bracket 200, it facilitates the fixation of the mounting bracket 200; on the other hand, a plurality of buckle holes 21 that are engaged with the buckle portion 43 can be provided, and it is beneficial to increase the effective contact area with the external water-cut insert 40, thereby effectively preventing the external water-cut insert 40 from rotating relative to the mounting bracket 200, and further improving the assembly stability of the external water-cut insert 40 and the mounting bracket 200.

[0069] Optionally, the clamping portion 32 and the external water-cut insert 40 are integrally injection molded. It can be understood that the external water-cut insert 40 is provided with a through hole 441. When the clamping portion 32 and the external water-cut insert 40 are integrally injection molded, part of the injection molding material is embedded in the through hole 441 to form a connecting protrusion 323, and the remaining injection molding material covers the external water-cut insert 40. The processing technology is simple, and the effective contact area between the external water-cut insert 40 and the clamping portion 32 is as large as possible, which is conducive to speeding up production efficiency and can also improve the connection firmness between the external water-cut insert 40 and the clamping portion 32.

[0070] Reference Figures 4 to 5 In one embodiment, the corner body 31 has a raised rib 311 protruding laterally in a direction perpendicular to the door assembly 100. The raised rib 311 is used to support the door assembly 100. By fitting the raised rib 311 with the door assembly 100, the tightness of the fit between the outer water-cut corner 30 and the door assembly 100 can be effectively improved, thereby improving the sealing performance of the vehicle.

[0071] Optionally, in one embodiment, the angle body 31 has a semi-enclosed annular structure, and at least one notch 312 is defined on the inner annular surface of the angle body 31. Multiple notches 312 may be provided, spaced apart, and positioned at locations where the angle body 31 primarily deforms when subjected to force. This facilitates reliable deformation of the angle body 31, improves the service life of the angle body 31, and ensures the effectiveness of the external water-cut angle 30. However, in other embodiments, the angle body 31 has a closed annular structure.

[0072] Reference Figures 1 to 4 、 Figure 9In one embodiment, a vehicle door assembly 100 includes an outer panel 11 and an inner panel 12. The inner panel 12 includes an inner panel body 121, a first connecting section 122, and a first bent section 123 connected between the inner panel body 121 and the first connecting section 122. The first connecting section 122 is in close contact with the outer panel 11, and the mounting bracket 200 is fixed to the first connecting section 122. It will be appreciated that the first bent section 123 connects the inner panel body 121 and the first connecting section 122, respectively, with a smooth transition, ensuring the smoothness of the overall curve of the inner panel 12. It also allows the first connecting section 122 to gradually approach and align with the outer panel 11, thereby preventing foreign matter such as water, dust, and sand from entering the vehicle door assembly 100 through the gap between the first connecting section 122 and the outer panel 11, thereby improving the sealing performance of the vehicle door assembly 100.

[0073] The mounting bracket 200 is fixed to the first connecting section 122, that is, the fixing portion 22 is fixedly connected to the first connecting section 122, so that the outer water cut angle 30 can be assembled on the upper end portion of the door assembly 100 away from the hinge with the vehicle body, and then can be tightly attached to the vehicle body, thereby playing a sealing role, further sealing the door assembly 100 and the vehicle body, and improving the sealing of the vehicle.

[0074] Furthermore, in one embodiment, the outer panel 11 includes a second connecting section 112, and the second connecting section 112 is provided with an inner flange 113 along its edge, and the inner flange 113 covers the first connecting section 122 to form a edging structure. It can be understood that the first connecting section 122 gradually approaches and fits with the second connecting section 112 on one side, wherein the second connecting section 112 is provided with an inner flange 113 along its edge, so that the inner flange 113 fits with the other side of the first connecting section 122, and then covers the first connecting section 122 to form a edging structure. At this time, the outer panel 11 and the inner panel 12 form a whole, thereby improving the connection firmness and sealing of the vehicle door assembly 100.

[0075] Reference Figure 9 In one embodiment, the outer panel 11 further includes an outer panel body 111. The outer panel body 111 and the inner panel body 121 are spaced apart to form a housing for the window glass 500. The outer watertight assembly 300 further includes an outer watertight body 33 connected to the outer watertight corner 30. The outer watertight body 33 is configured to contact one side of the window glass 500, and the top of the outer watertight body 33 is lower than the top of the outer panel body 111. This ensures that the outer watertight body 33 is hidden on the side of the outer panel body 111 facing the inner panel body 121, effectively ensuring the aesthetic appearance of the vehicle.

[0076] Specifically, the outer panel body 111 and the second connecting section 112 have a smooth transition, and a fixing bracket 34 is fixed on the inner side. The outer water-cut body 33 is fixed on the fixing bracket 34 and is provided with a sealing lip, which contacts the vehicle window glass 500 to form a complete sealing buffer structure.

[0077] An inner water cut assembly 400 is mounted on the inner panel body 121 , and the inner water cut assembly 400 is in contact with the other side of the window glass 500 to further enhance the sealing performance.
