[0033] See also Figure 1 and Figure 2 As shown, the vehicle door corner structure according to an 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 is 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 connecting end 111 is flush with the top edge of the body 110, and the connecting block 113 is provided at the top edge of the body 110, and the connecting block 113 is provided away from the first connecting end 111, and the connecting block 113 protrudes from the top edge of the body 110. Thus, there is a straight surface between the end surface of the first connecting end 111 and the connecting block 113. Figure 2 In the example shown in FIG, the connecting block 113 is disposed at the right end of the top side of the main body 110 .
[0035] The bubble tube portion 211 of the upper sealing strip 210 is connected to the first connecting end 111. 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 the flat surface between the end face of the first connecting end 111 and the connecting block 113. The large lip 212 and the flat surface can be snapped or bonded. In this way, the top edge of the body 110 supports the large lip 212, which helps maintain the straightness of the upper sealing strip 210 and improves 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 portion 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 this application, by staggering the connection positions of the bubble tube portion 211, the large lip 212, and the door corner structure, the body 110 provides support for the large lip 212, improving the stability of the connection between the door corner structure and the upper sealing strip 210 and ensuring better straightness of the upper sealing strip 210. It is understood that due to manufacturing tolerances, a certain height difference between the upper edge of the first connecting end 111 and the top edge of the bubble tube portion 211 is permitted, 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 aligning the upper edge of the first connecting end 111 with the top edge of the body 110, and disposing the connecting block 113 on the top edge of the body 110 away from the first connecting end 111, the bubble tube portion 211 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 is connected to the connecting block 113. This avoids the connection between the upper sealing strip 210 and the vehicle door corner structure being concentrated in one place, and provides support for the large lip 212. As a result, the large lip 212 can overlap the surface between the end face of the first connecting end 111 and the connecting block 113, giving the upper sealing strip 210 better straightness and improving the stability and sealing performance 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. The insert 120 is connected to the main body 110, and one side of the insert 120 is in contact with the main body 110. The projected 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. Therefore, 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 provided 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 into 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 and 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 plugs into the bubble tube portion 211 is the same as the cross-section of the cavity within the bubble tube portion 211, so that the plug-in section 121 fits closely to 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 flanges 122 at the upper edge of the insert 120 extend 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 base 123 and a mounting buckle 124. The mounting buckle 124 is provided on one side of the base 123 and is buckled with the door inner panel 222. The mounting buckle 124 and the base 123 are integrally formed to improve the structural strength of the connection between the mounting buckle 124 and the base 123 and to meet the needs of multiple disassembly and assembly of the insert 120. The base 123 and the mounting buckle 124 are integrally injection molded. Figure 3 and Figure 5 As shown, the base 123 is generally plate-shaped, one side of the base 123 is connected to the body 110, and the other side of the base 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 to have a certain degree of 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 vehicle door corner structure and other vehicle door components, thereby further improving the sealing performance of the vehicle 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 116 and the third lip 117 are both upward and left (as shown in FIG. Figure 3 As shown in the figure, the second lip 116 and the third lip 117 extend upwards to form an acute angle with the main body 110. This can improve the sealing performance of the second lip 116 and the third lip 117 in contact with the window frame bright strip 221. And a small amount of water that enters between the window frame bright strip 221 and the main body 110 can be guided to flow to the acute angle to prevent the water from further flowing into the interior of the vehicle 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 performance 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 performance 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 window frame, and the support boss 118 is suitable for abutting against the window frame sheet metal. For example, when the vehicle door is closed, the support boss 118 abuts against the window frame sheet metal to provide support for the main body 110 of the vehicle door corner structure, thereby reducing or avoiding deformation caused by pressing on the side of the main body 110 facing away from the vehicle door frame, and further improving the stability of the vehicle 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 connected to the first side 114. The elastic contact member 119 is adapted to abut against the window frame sheet metal, thereby ensuring a closer contact between the door corner structure and the window frame, preventing any gaps, improving sealing, and providing a certain shock-absorbing effect. The elastic contact member 119 may be a foam member or a rubber member.
[0045] The present application also provides a vehicle door, comprising an upper sealing strip 210 and the above-described vehicle door corner structure. The upper sealing strip 210 is connected to the vehicle door corner structure. The bubble tube portion 211 of the upper sealing strip 210 is connected to the first connection end 111 of the vehicle door corner structure. The large lip 212 of the upper sealing strip 210 extends along the top edge of the body 110 to the connection block 113 and is connected to the connection block 113. This improves the stability of the connection between the upper sealing strip 210 and the vehicle door corner structure, thereby improving the sealing performance of the vehicle door. In some embodiments, the vehicle door further comprises a side sealing strip 213. A second connection end 112 is provided between the first side edge 114 and the bottom edge of the body 110. The side sealing strip 213 is connected to the second connection end 112, thereby fixedly connecting the upper sealing strip 210 and the side sealing strip 213 of the vehicle door via the vehicle door corner structure.
[0046] In summary, the embodiments of the present invention provide a door corner structure, which has the following beneficial effects:
[0047] 1. Improve the installation stability of the upper sealing strip, make it have better straightness, and improve the sealing of the car door;
[0048] 2. The overall structure of the door corner structure has good stability and strong support.
