[0055] The directional words appearing in the following description are all directions shown in the figures and do not limit the specific structure of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0056] Figure 1 The figure shows a door sealing strip system between a door opening and a door of a vehicle 1000 in the related art. Figure 2 A vehicle door window frame structure assembly 100 in the related art is shown.

[0057] See also Figure 1 and Figure 2In the related art, the automobile door and window frame structure assembly 100 and the door opening are important components of the vehicle body. They provide a passage for the driver and passengers to get on and off the vehicle, while also ensuring sound insulation and noise isolation for passengers while the vehicle is in motion, providing lateral safety for the passengers.

[0058] Among them, the door sealing strip system between the door opening of the vehicle 1000 and the door window frame structure assembly 100 is one of the indispensable important components for realizing the functions of the door opening and the vehicle 1000.

[0059] See also Figure 2 , Figure 2 The door and window frame structure assembly 100 shown in the figure is a split door with a frame-under-glass (FUG) structure, which consists of a full-size stamped inner panel P0, a window frame reinforcement panel P1, and a half-size stamped outer panel P2 covering the door. The door and window frame structure assembly 100 above the window sill only includes a two-layer structure of the stamped inner panel P0 and the window frame reinforcement panel P1, and is not covered by the stamped outer panel P2.

[0060] Therefore, in this vehicle door window frame structure assembly 100, the internal structure of the entire window frame is exposed to the outside, and some decorative accessories need to be installed on the internal structure of the window frame to form the outer surface structure of the window frame, such as decorative panels or decorative strips that fit the window frame.

[0061] See also Figure 1 , applied to this door and window frame structure assembly 100, the door sealing strip system between the door opening and the door of the vehicle 1000 includes three (including two and a half) sealing strips, including a complete sealing strip S0 installed on the door opening of the vehicle body, a complete sealing strip S1 installed on the inside of the door, and a sealing strip S2 installed on the outside of the door.

[0062] The sealing strip S2 installed on the outside of the vehicle door adopts a two-strip solution, including a half sealing strip installed only on the window frame and the pillar (A-pillar) between the front windshield and the door window frame structure assembly 100, and a three-strip solution that fully covers the outside of the vehicle body, depending on the cost, sealing performance and noise, vibration and harshness (NVH) requirements of the entire vehicle.

[0063] The sealing strip S2 installed on the outside of the vehicle door includes not only the sealing strip but also the sealing strip corners. Both ends of the sealing strip corners are connected to the sealing strip respectively, and together with the sealing strip, they play a sealing role in the single vehicle door window frame structure assembly 100.

[0064] However, the sealing strip S2 installed on the outside of the vehicle door, in the transition area A0 between the front door and the rear door, that is, the pillar (B-pillar) between the front door and the rear door, except that the sealing strip and the B-pillar are fitted together to form a sealing structure on a single door, whether it is a two-and-a-half- or three-strip sealing strip system, in the transition area A0 between the front door and the rear door, the sealing strip of the front door and the sealing strip of the rear door cannot form a continuous sealing structure in the transition area. Therefore, the sealing performance and NVH performance of the vehicle 1000 can be further improved.

[0065] Out of technical needs and considerations for solving the above-mentioned problems, the applicant invented a design scheme in which the sealing strips arranged on the outside of the front and rear doors overlap with the corners of the sealing strips on the side where the B-pillar is in contact, thereby forming a complete sealing structure in the transition area A0 of the front and rear doors.

[0066] Figure 3 The structure of a sealing strip corner assembly 10 provided by an embodiment of the first aspect of the present application is shown. Figure 4 The structure of a vehicle door and window frame structure assembly 100 provided by an embodiment of the second aspect of the present application is shown. Figure 5 Shown Figure 4 The cross-sectional structure along the AA direction, Figure 6 It shows Figure 4 Cross-sectional structure along BB direction.

[0067] See also Figures 3 to 6 In a first aspect, an embodiment of the present application provides a sealing strip corner combination 10 , comprising a first sealing strip corner 11 and a second sealing strip corner 12 .

[0068] The first sealing strip corner 11 includes a first mounting body 110 and a first joining portion 111 and a second joining portion 112 arranged along the outer edge of the first mounting body 110. The first joining portion 111 also includes a first connecting lip 111a, which extends from the first joining portion 111 in a direction away from the first mounting body 110.

[0069] The second sealing strip corner 12 includes a second mounting body 120 and a third joining portion 121 and a fourth joining portion 122 arranged along the outer edge of the second mounting body 120. The third joining portion 121 also includes a second connecting lip 121a, and the fourth joining portion 122 also includes a overlapping lip 122a. The second connecting lip 121a extends from the third joining portion 121 in a direction away from the second mounting body 120, and the overlapping lip extends from the fourth joining portion 122 in a direction away from the second mounting body 120. The second sealing strip corner also includes a corner portion 12a connecting the second connecting lip 121a and the overlapping lip 122a.

[0070] The sealing strip corner combination 10 provided in the embodiment of the first aspect of the present application, after the first sealing strip corner 11 and the second sealing strip corner 12 are installed, the overlapping lip 122a of the second sealing strip corner 12 in the sealing strip corner combination 10 can cover the transition area between the first sealing strip corner 11 and the second sealing strip corner 12, part of the structure of the first sealing strip corner 11 overlaps with the overlapping lip 122a, and the corner portion 12a between the second connecting lip 121a in the second sealing strip corner 12 and the overlapping lip 122a is at least partially overlapped with the first connecting lip 111a in the first sealing strip corner 11, forming a coherent sealing structure in the transition area between the first sealing strip corner 11 and the second sealing strip corner 12.

[0071] In the first sealing strip corner 11, the first mounting body 110 is used to fix the first sealing strip corner 11 on the vehicle door structure, and the first mounting body 110 needs to provide certain support and anti-deformation functions to ensure that the first joining portion 111 and the second joining portion 112 can be smoothly connected with other structures of the vehicle door.

[0072] The first engaging portion 111 and the second engaging portion 112 are provided with different cross-sectional shapes according to other structures of the vehicle door, so as to match the cross-sectional shapes of other structures on the vehicle door to be connected.

[0073] The first joint portion 111 is further provided with a first connecting lip 111 a , which can connect with the sealing strip on the door structure after being installed on the door structure, making it more beautiful.

[0074] Similarly, in the second sealing strip corner 12, the second mounting body 120 is used to fix the second sealing strip corner 12 on the vehicle door structure and provide certain support and anti-deformation functions. The third joining portion 121 and the fourth joining portion 122 are provided with different cross-sectional shapes according to other structures of the vehicle door. The third joining portion 121 is also provided with a second connecting lip 121a, which can be connected with the sealing strip on the vehicle door structure.

[0075] Among them, the fourth joint portion 122 is also provided with an overlapping lip 122a, which is used to cover a portion of the transition area between the vehicle doors. When the first sealing strip corner 11 in the sealing strip corner combination 10 is installed, the first sealing strip corner 11 can also overlap with the overlapping lip 122a to form a continuous sealing structure, thereby improving the sealing performance and NVH performance of the vehicle 1000.

[0076] A corner portion 12a is also provided between the overlapping lip 122a and the second connecting lip 121a. The corner portion 12a is used to smoothly connect the overlapping lip 122a and the second connecting lip 121a. After the first sealing strip corner 11 and the second sealing strip corner 12 in the sealing strip corner combination 10 are installed, the first connecting lip 111a and the second connecting lip 121a can also be overlapped to form a continuous sealing structure in the transition area between the other part of the vehicle doors, thereby further improving the sealing performance and NVH performance of the vehicle 1000.

[0077] Optionally, along the outer edge of the first installation body 110 and the second installation body 120, in addition to the outer edge portions of the first joint portion 111, the second joint portion 112, the third joint portion 121 and the fourth joint portion 122, the outer edges of the first installation body 110 and the second installation body 120 are also provided with a sealing lip 16. The sealing lip 16 is used to seal the gap between the first installation body 110 and the second installation body 120 and the vehicle door structure, thereby ensuring that the first sealing strip corner 11 and the second sealing strip corner 12 are tightly connected to the vehicle door, respectively, and the connection effect is stable.

[0078] Optionally, the first sealing strip corner 11 and the second sealing strip corner 12 in the sealing strip corner combination 10 are both integrally formed using an injection molding process, and can be manufactured into any desired shape according to different door structures, thereby reducing production costs and achieving a high degree of matching with the door structure, avoiding the limitation that the shapes of the first sealing strip corner 11 and the second sealing strip corner 12 need to be reassembled according to different door structures and cannot be completely accurately matched.

[0079] See also Figures 4 to 6 In some embodiments, in the assembled state, the first sealing strip corner 11 cooperates with the second sealing strip corner 12, part of the first sealing strip corner 11 overlaps with the overlapping lip 122a, and the first connecting lip 111a overlaps with the corner portion 12a.

[0080] In these embodiments, when assembled on the vehicle door window frame structure assembly 100, the overlapping lip 122a can cover the transition area between the first sealing strip corner 11 and the second sealing strip corner 12 and overlap with a portion of the first sealing strip corner 11, while the corner portion 12a and the first connecting lip 111a overlap with each other, thereby achieving sealing of the transition area.

[0081] The assembly state should be understood as that the first sealing strip corner 11 and the second sealing strip corner 12 are installed to the required assembly positions on the door and window frame structure assembly 100. At this time, when the entire vehicle is working normally, the relative positions of the first sealing strip corner 11 and the second sealing strip corner 12 can be kept fixed.

[0082] In the assembled state, the overlapping lip 122a is used to cover a portion of the transition area between the vehicle doors, and the first sealing strip corner 11 can also overlap with the overlapping lip 122a to form a continuous sealing structure, thereby improving the sealing performance and NVH performance of the vehicle 1000.

[0083] In addition to being used to smoothly connect the overlapping lip 122a and the second connecting lip 121a, the corner portion 12a can also overlap the first connecting lip 111a and the second connecting lip 121a in the assembled state to form a continuous sealing structure in the transition area between the other parts of the vehicle doors, further improving the sealing performance and NVH performance of the vehicle 1000.

[0084] Figure 7 Shown Figure 3 The cross-sectional structure along CC direction, Figure 8 Shown Figure 3 Cross-sectional structure along DD direction.

[0085] See also Figure 3 as well as Figures 7 and 8 In some embodiments, the second joining portion 112 further includes a first joining end 112a and a second joining end 112b, and the fourth joining portion 122 further includes a third joining end 122b, a fourth joining end 122c and a limiting boss 122d, and the limiting boss 122d is arranged along the edge of the overlapping lip 122a away from the corner portion 12a.

[0086] In these embodiments, the first joining end 112a and the second joining end 112b respectively match the shapes of the door panel structures of different layers in the vehicle door structure, and the third joining end 122b and the fourth joining end 122c also respectively match the door panel structures of different layers in the vehicle door, which can cover the sheet metal cuts in the vehicle door structure, making it more beautiful and enhancing the sense of refinement.

[0087] Among them, since the fourth joint end 122c is separately provided with an overlapping lip 122a, in order to reduce the misalignment error between the overlapping lip 122a and other structures subsequently installed on the side of the overlapping lip 122a, further limiting the other structures is formed, which can make the overlapping lip 122a and other structures have a smooth transition in shape, more beautiful, and further enhance the sense of refinement.

[0088] The door structure includes a full-size stamped inner panel and a window frame reinforcement plate in the window frame part. In the second joint part 112 of the first sealing strip corner 11, the first joint end 112a and the second joint end 112b can be connected with the full-size stamped inner panel and the window frame reinforcement plate respectively, which makes the installation more stable and can cover the sheet metal cuts of the full-size stamped inner panel and the window frame reinforcement plate, and also enhance the sense of refinement.

[0089] Similarly, in the fourth joint portion 122 of the second sealing strip corner 12, the third joint end 122b and the fourth joint end 122c are also connected to the full-size stamped inner panel and the window frame reinforcement plate, which is stable and more refined.

[0090] Since the second sealing strip corner 12 is additionally provided with a lap lip 122a for covering the transition area at the fourth joint portion 122, the lap lip 122a is not connected with other structures on the vehicle door. The fourth joint portion 122 is also provided with a limiting boss 122d, so that other structures subsequently installed at the fourth joint portion 122 can be smoothly connected with the lap lip 122a in shape, thereby further enhancing the sense of refinement.

[0092] See also Figure 3 as well as Figures 7 to 9 In some embodiments, the first sealing strip corner 11 further includes a first overlapping portion 113 arranged between the first joining portion 111 and the second joining portion 112. The first overlapping portion 113 includes a first overlapping lip tip 113a, a first supporting portion 113c and a first clamping groove 113b arranged between the first overlapping lip tip 113a and the first supporting portion 113c. The first overlapping lip tip 113a protrudes from the root of the first connecting lip edge 111a in a direction away from the first installation body 110, and the first supporting portion 113c protrudes from the first installation body 110 in a direction away from itself.

[0093] The second sealing strip corner 12 also includes a second overlapping portion 123 arranged between the third joining portion 121 and the fourth joining portion 122. The second overlapping portion 123 includes a second overlapping lip tip 123a, a second supporting portion 123c and a second clamping groove 123b arranged between the first overlapping lip tip 113a and the second supporting portion 123c. The second overlapping lip tip 123a protrudes from the root of the second connecting lip edge 121a in a direction away from the second installation body 120, and the second supporting portion 123c protrudes from the second installation body 120 in a direction away from itself.

[0094] In these embodiments, the first overlap portion 113 and the second overlap portion 123 are used for the subsequent installation of the decorative strip structure. The decorative strip structure can be fixed by the first snap-fit ​​groove 113b and the second snap-fit ​​groove 123b, and is limited by the first overlap lip tip 113a and the second overlap lip tip 123a. The first support portion 113c and the second support portion 123c can avoid the risk of deformation caused by the decorative strip structure squeezing the first sealing strip corner combination 10 and the second sealing strip corner combination 10 after the decorative strip structure is installed.

[0095] Optionally, the first overlap portion 113 and the second overlap portion 123 are further provided with at least one measuring mark point 17. When the first sealing strip corner 11 and the second sealing strip corner 12 are installed, the length from the measuring mark point 17 to a specific position of the vehicle door or vehicle body can be detected and the error can be compared with the standard length to determine whether the installation position is accurate to the extent that meets actual needs, and to facilitate adjustment.

[0112] Optionally, the first exterior panel 102a and the second exterior panel 104a may also be provided with sealing strips. The sealing strip of the first exterior panel 102a, the first matching lip 101a and the first sealing strip corner 11 form a complete sealing strip, which can further improve the sealing performance and NVH performance of the vehicle 1000.

[0113] The sealing strip of the second exterior panel 104a, the second matching lip 103a and the second sealing strip corner 12 form a complete sealing strip, which can further improve the sealing performance and NVH performance of the vehicle 1000.

[0114] In some embodiments, the second joint portion 112 further includes a first joint end and a second joint end, and the fourth joint portion further includes a third joint end, a fourth joint end and a limiting boss, which is arranged along the edge of the overlapping lip away from the corner portion 12a.

[0115] The first joint end and the second joint end respectively match the shapes of the door panel structures of different layers in the vehicle door structure, and the third joint end and the fourth joint end also respectively match the door panel structures of different layers in the vehicle door, which can cover the sheet metal cuts in the vehicle door structure, making it more beautiful and enhancing the sense of refinement.

[0116] Among them, since the fourth joint end is separately provided with an overlapping lip 122a, in order to reduce the misalignment error between the overlapping lip 122a and the second exterior panel 104a and the optional sealing strip subsequently installed on the periphery of the overlapping lip 122a, the second exterior panel 104a and the optional sealing strip are further limited by an additional structure, which can make the overlapping lip 122a and the second exterior panel 104a and the optional sealing strip have a smooth transition in shape, more beautiful, and further enhance the sense of refinement.

[0117] The door structure includes a full-size stamped inner panel and a window frame reinforcement plate in the window frame part. In the second joint part 112 of the first sealing strip corner 11, the first joint end and the second joint end can be connected with the full-size stamped inner panel and the window frame reinforcement plate respectively, which makes the installation more stable and can cover the sheet metal cuts of the full-size stamped inner panel and the window frame reinforcement plate, and also enhance the sense of refinement.

[0118] Similarly, in the fourth joint portion 122 of the second sealing strip corner 12, the third joint end and the fourth joint end are also connected to the full-size stamped inner panel and the window frame reinforcement plate, which is stable and more refined.

[0119] Since the second sealing strip corner 12 is additionally provided with a lap lip 122a for covering the transition area at the fourth joint 122, the lap lip 122a is not connected with the second exterior panel 104a on the vehicle door and the optional sealing strip. The fourth joint 122 is also provided with a limiting boss so that the second exterior panel 104a and the optional sealing strip subsequently installed at the fourth joint 122 can be smoothly connected in shape with the lap lip 122a, thereby further enhancing the sense of refinement.
