[0033] See also Figure 1 and Figure 2 As shown, the door corner structure according to the embodiment of the present application includes a main body 110 .

[0034] Specifically, the body 110 is provided with a first connection end 111 and a connection block 113, the first connection end 111 is located between the top edge of the body 110 and the first side edge 114 of the body 110, the upper edge of the first connection end 111 is flush with the top edge of the body 110, the connection block 113 is provided at the top edge of the body 110, and the connection block 113 is provided away from the first connection end 111. Figure 2 The main body 110 is roughly quadrilateral, and a first connecting end 111 is formed at the connection between the first side 114 and the top edge. The end surface of the first connecting end 111 is located on the left side (such as Figure 2 ), the upper edge of the first connection end 111 is flush with the top edge of the body 110, the connection block 113 is disposed at the top edge of the body 110, and the connection block 113 is disposed away from the first connection end 111, and the connection block 113 protrudes from the top edge of the body 110. Thus, there is a straight surface from the end surface of the first connection end 111 to the connection block 113. Figure 2 In the example, the connection block 113 is disposed at the right end of the top edge of the main body 110 .

[0035] The body 110 of the upper sealing strip 210 is connected to the first connecting end 111, and the large lip 212 of the upper sealing strip 210 extends along the top edge of the body 110 to the connecting block 113 and is connected to the connecting block 113. The large lip 212 can overlap on the flat surface between the end face of the first connecting end 111 and the connecting block 113, and the large lip 212 can be clamped or bonded to the surface. In this way, the top edge of the body 110 has a supporting effect on the large lip 212, which is conducive to maintaining the straightness of the upper sealing strip 210 and improving the stability and sealing of the connection between the door corner structure and the upper sealing strip 210. In the related art, the connection position of the large lip 212 and the door corner structure is flush with the connection position of the bubble tube part 211 and the door corner structure, the structural stability of the connection is poor, and the upper sealing strip 210 is prone to collapse and deformation, which in turn affects the sealing of the upper sealing strip 210. In the present application, the connection positions of the bubble tube portion 211, the large lip edge 212 and the door corner structure are staggered, so that the body 110 provides support for the large lip edge 212, improves the stability of the connection between the door corner structure and the upper sealing strip 210, and makes the upper sealing strip 210 have better straightness. It is understandable that due to manufacturing errors, the upper edge of the first connecting end 111 and the top edge of the bubble tube portion 211 can have a certain height difference, as long as it does not affect the installation of the upper sealing strip 210.

[0036] According to the vehicle door corner structure of the embodiment of the present invention, by making the upper edge of the first connection end 111 flush with the top edge of the body 110, the connection block 113 is arranged on the top edge of the body 110 away from the first connection end 111, the bubble tube portion 211 of the upper sealing strip 210 is connected to the first connection end 111, and the large lip edge 212 of the upper sealing strip 210 is connected to the connection block 113, so as to avoid the connection between the upper sealing strip 210 and the vehicle door corner structure being concentrated in one place, and provide support for the large lip edge 212. Therefore, the large lip edge 212 can overlap the surface between the end face of the first connection end 111 and the connection block 113, so that the upper sealing strip 210 has better straightness, and improves the stability and sealing of the connection between the vehicle door corner structure and the upper sealing strip 210.

[0037] According to some embodiments of the present application, the door corner structure also includes an insert 120, which is generally plate-shaped, connected to the main body 110, one side of the insert 120 is in contact with the main body 110, and the projection area of ​​the insert 120 on the plane where the main body 110 is located is greater than or equal to the area of ​​the main body 110, so that the insert 120 can cover the entire main body 110 and improve the structural stability of the main body 110.

[0038] like Figure 2 and Figure 4As shown, according to some embodiments of the present application, the insert 120 is provided with a plug-in section 121, which is inserted through the first connection end 111, and the end of the plug-in section 121 protrudes from the first connection end 111 to be plugged with the upper sealing strip 210. On the one hand, the stability of the connection between the door corner structure and the upper sealing strip 210 can be improved, and on the other hand, the plug-in section 121 can support the upper sealing strip 210 to reduce the probability of collapse and deformation of the upper sealing strip 210. Figure 4 A strip-shaped plug-in section 121 extends from the left side of the insert 120. After the insert 120 is connected to the body 110, as shown in FIG. Figure 2 , the end of the plug-in section 121 extends from the first connection end 111, the bubble tube portion 211 of the upper sealing strip 210 is connected to the first connection end 111, and the plug-in section 121 is inserted into the bubble tube portion 211. This strengthens the connection strength between the bubble tube portion 211 and the first connection end 111, and provides support for the bubble tube portion 211. In some embodiments, the cross-section of the portion where the plug-in section 121 is plugged into the bubble tube portion 211 is the same as the cross-section of the cavity in the bubble tube portion 211, so that the plug-in section 121 fits the inner wall of the bubble tube portion 211 for support.

[0039] like Figure 4 As shown, according to some embodiments of the present application, at least one side edge of the insert 120 is provided with a flange 122 to improve the structural strength of the insert 120. Figure 4 In the example, flanges 122 are provided at the upper edge and the right edge of the insert 120 , wherein the flange 122 at the upper edge of the insert 120 extends to the plug-in section 121 to improve the structural strength of the plug-in section 121 .

[0040] According to some embodiments of the present application, the insert 120 includes a seat body 123 and a mounting buckle 124. The mounting buckle 124 is provided on one side of the seat body 123. The mounting buckle 124 is buckled with the door inner panel 222. The mounting buckle 124 and the seat body 123 are integrally formed to improve the structural strength of the connection between the mounting buckle 124 and the seat body 123, and to meet the needs of multiple disassembly and assembly of the insert 120. The seat body 123 and the mounting buckle 124 are integrally injection molded. Figure 3 and Figure 5 As shown, the seat body 123 is generally plate-shaped, one side of the seat body 123 is connected to the body 110, and the other side of the seat body 123 is provided with a mounting buckle 124, which is buckled to the door inner panel 222. The mounting buckle 124 is cage-shaped as a whole, so as to have a certain deformation ability, which is convenient for disassembly or installation.

[0041] like Figure 3 As shown, according to some embodiments of the present application, the side of the body 110 facing away from the door frame is provided with a Figure 3The first lip 115 abuts against the side outer panel 220 of the vehicle door, and the second lip 116 and the third lip 117 abut against the window frame bright strip 221, forming a three-line sealing structure to seal the connection between the door corner structure and other door components, thereby further improving the sealing performance of the door corner structure.

[0042] According to some embodiments of the present application, the second lip 116 is inclined upward from its root to its end, and the third lip 117 is inclined upward from its root to its end. Figure 3 As shown, the second lip edge 116 and the third lip edge 117 are both facing upward to the left (as shown in FIG. Figure 3 As shown in the figure, the second lip 116, the third lip 117 and the body 110 form an upward acute angle. In this way, the sealing of the second lip 116, the third lip 117 and the window frame bright strip 221 can be improved. And a small amount of water that enters between the window frame bright strip 221 and the body 110 can be guided to the acute angle to prevent the water from further flowing into the door. In some embodiments, the length of the first lip 115 is set so that it is compressed and deformed to a certain extent after abutting against the side outer panel 220, thereby improving the sealing of the connection between the first lip 115 and the side outer panel 220. Similarly, the lengths of the second lip 116 and the third lip 117 are set so that they are compressed and deformed to a certain extent after abutting against the window frame bright strip 221, thereby improving the sealing of the connection.

[0043] See also Figure 1 As shown, according to some embodiments of the present application, a support boss 118 is provided on the side of the main body 110 facing the door frame, and the support boss 118 is suitable for abutting against the window frame sheet metal. For example, when the door is closed, the support boss 118 abuts against the window frame sheet metal to provide support for the main body 110 of the door corner structure, thereby reducing or avoiding deformation of the side of the main body 110 facing away from the door frame after being pressed, thereby further improving the stability of the door corner structure.

[0044] like Figure 1 As shown, according to some embodiments of the present application, the door corner structure further includes an elastic contact member 119, which is connected to the first side 114. The elastic contact member 119 is suitable for abutting against the window frame sheet metal, so that the door corner structure is in closer contact with the window frame, avoiding separation, improving sealing, and having a certain shock absorption effect. The elastic contact member 119 can be a foam or rubber member.
