[0038] Reference below Figure 1-Figure 8 , describing a door assembly 10 and a vehicle according to an embodiment of the present application.

[0039] The vehicle door assembly 10 according to the embodiment of the present application includes a vehicle door exterior panel 11 , a vehicle door sheet metal 12 and a connecting member 13 .

[0040] refer to Figure 1 As shown, the door trim panel 11 is arranged opposite to the door sheet metal 12 (in the inward and outward directions of the vehicle, that is, the door sheet metal 11 is closer to the interior space of the vehicle than the door trim panel 12). One side of the door trim panel 11 is an appearance surface for forming the appearance of the vehicle; the other side is an installation surface for matching with the door sheet metal 12. A plurality of fasteners can be arranged between the installation surface and the door sheet metal 12 to connect the two.

[0041] It should be pointed out that the door exterior panels 11 are mostly aluminum alloy parts or sheet metal parts. In order to improve the appearance of the vehicle, different appearance surfaces are often processed on the door exterior panels 11. For example, based on water cutting, the appearance surface of the door exterior panels 11 is limited to multiple continuous rounded appearance surfaces or flat appearance surfaces (that is, different shapes are created) to create different vehicle styles, such as sports style, business style, etc.

[0042] However, the door exterior panel 11 is constructed into a specific shape to achieve an aesthetic effect, and the distance between the door exterior panel 11 and the door sheet metal 12 will fluctuate. In some areas, the distance between the door sheet metal 12 and the door exterior panel 11 is large, and in some areas, the distance between the door sheet metal 12 and the door interior panel 11 is small. In areas with larger distances, conventional fastening structures such as bolt fastening structures and latch fastening structures can be directly set to meet the connection strength requirements, while areas with smaller distances will have space limitations and it is difficult to set conventional fastening structures.

[0043] That is to say, since the door assembly 10 is at least matched with a door exterior trim 11 and a door sheet metal 12 in the thickness direction, the space between the door exterior trim 11 and the door sheet metal 12 will be significantly reduced in the area with smaller thickness, so that there is not enough space to reasonably arrange and set fasteners, which makes it difficult to ensure the connection strength between the door exterior trim 12 and the door panel 12.

[0044] For example, Figure 1-Figure 2 as well as Figure 7 As shown, the door sheet metal 12 and the door exterior panel 11 are connected by a latch 111, which is used as a fastener to ensure that the door exterior panel 11 is firmly fixed to the door sheet metal 12. However, the lower edge of the door exterior panel 11 is closer to the door sheet metal 12, so that the door assembly 10 is constructed thinner in the lower edge area to improve the visual aesthetic effect. In this case, the space between the door exterior panel 11 and the door sheet metal 12 is significantly reduced, and the length of the latch 11 cannot be accommodated, so that the installation space of the latch 111 is limited, resulting in difficulty in its installation, or even ineffective installation, which in turn affects the overall structure and performance of the door assembly 10.

[0045] To this end, the vehicle door assembly 10 in this embodiment is also provided with the aforementioned connecting member 13; Figure 1-Figure 2 For example, the connecting member 13 includes a first plate 131 , a second plate 132 and a third plate 133 .

[0046] like Figure 2 As shown, the first plate 131 is connected to the side of the door exterior panel 11 facing the door sheet metal 12, that is, the installation surface of the door exterior panel 11; the two ends of the second plate 132 are respectively connected to the first plate 131 and the third plate 133, and the third plate 133 is arranged opposite to the first plate 131 to define a limiting groove a, the lower edge of the door sheet metal 12 is arranged in the limiting groove a, and the third plate 133 is suitable for pushing against the door sheet metal 12.

[0047] The first plate 131 in the connecting member 13 is arranged on the mounting surface, so that the connecting member 13 is fixedly connected to the door exterior panel 11. The first plate 131, as a direct connection portion between the connecting member 13 and the door exterior panel 11, can provide a fixing base for the connecting member 13. Furthermore, the limiting groove a defined by the third plate 133 and the first plate 131 can accommodate the door sheet metal 12; in this way, the edge of the door sheet metal 12 is defined between the first plate 131 and the third plate 133, and the side of the door sheet metal 12 away from the door exterior panel 11 is pushed by the third plate in the thickness direction of the door sheet metal 12, so that the movement of the door sheet metal 12 is restricted, thereby maintaining the relative position between the door exterior panel 11 and the door sheet metal 12.

[0048] That is to say, the connecting member 13 is fixed to the door exterior panel 11 through the first plate 131, and at the same time, the door sheet metal 12 is clamped and fixed through the limiting groove a, so that the door exterior panel 11 and the door panel 12 are fixed to the edge area where the distance between the door exterior panel 11 and the door panel 12 is small and it is difficult to arrange a conventional fastening structure.

[0049] Therefore, the third plate 133 extends to the side of the door sheet metal 12 away from the door exterior panel 11 to form a limit, so that the third plate 133 and the second plate 132 are not restricted by the size of the interval space between the door exterior panel 11 and the door sheet metal 12 (that is, they are not restricted by the specific shape of the door exterior panel 11), and can be constructed into different sizes and shapes according to actual needs to provide sufficient limiting effect on the door sheet metal 12, and can ensure the limiting effect of the connecting part 13 on the door sheet metal 12, thereby providing sufficient connection strength between the door sheet metal 12 and the door exterior panel 11, and preventing the door exterior panel 11 from warping and detaching relative to the door sheet metal 12.

[0050] It is worth noting that, as a component of the vehicle's exterior, the flatness and integrity of the door trim 11 directly affect the overall aesthetics of the vehicle, so it is necessary to ensure the structural integrity of the door trim 11. As for the door sheet metal 12, it is usually connected to other components (such as door frames, anti-collision beams, etc.) through the hemming process. If a hole is opened near the edge of the door sheet metal 12, the integrity of the hemming structure will be destroyed; similarly, additional holes in the door sheet metal 12 may also affect the welding process of the door sheet metal 12. The holes may affect the preset weld path, resulting in discontinuous welding, and further affecting the overall strength and safety of the door; the gluing process on the door sheet metal 12 will also be affected by the holes. Making additional holes in the door sheet metal 12 may destroy the continuity of the glue layer, resulting in reduced sealing performance, and noise and moisture are more likely to invade the vehicle.

[0051] Therefore, it is not possible to drill holes in the door trim 11 or the door sheet metal 12 to install fasteners to overcome the problem of insufficient installation space due to the partial area of ​​the door trim 11 being closer to the door sheet metal 12. To this end, the fasteners need to be constructed as latches 111 or buckles extending from the mounting surface or the door sheet metal 12, and are arranged in the space defined by the door trim 11 and the door sheet metal 12 to ensure the structural integrity of the door trim 11 and the door sheet metal 12. For example, Figure 5 As shown, on the mounting surface of the door trim panel 11 at the lower edge of the door assembly 10 , the fastener is configured as a latch 111 extending from the door trim panel 11 to fix the door trim panel 11 to the door sheet metal 12 .

[0052] Accordingly, the first plate 131 in the connecting member 13 is arranged on the mounting surface so that the first plate is hidden in the door exterior panel, and there is no need to open a hole or form a protruding structure on the door exterior panel 11, thereby ensuring the flatness and integrity of the door exterior panel 11. In addition, the second plate 132 is located below the door sheet metal 12, and avoids the door sheet metal 12 by forming a limiting groove a, so that the second plate 132 is located outside the interval between the door exterior panel and the door sheet metal 12; the third plate 133 is located in the door sheet metal 12, away from the side of the door exterior panel 11, that is, the third plate 133 is located outside the interval between the door exterior panel and the door sheet metal 12, so that the second plate 132 and the third plate 133 extend around the edge of the door sheet metal 12. In this way, the second plate 132 can extend from one side of the door sheet metal 12 to the other side without opening a hole in the door sheet metal 12 , and the door sheet metal 12 can be limited by the third plate 133 to maintain the integrity of the door sheet metal 12 .

[0053] That is to say, compared with the conventional door assembly 10, the distance between the door exterior panel 11 and the door sheet metal 12 is insufficient due to the specific shape of the door exterior panel 11, making it difficult to arrange fasteners. The connector 13 in this embodiment can limit the door sheet metal 12 through the limiting groove a, keeping the second plate 132 and the third plate 133 outside the spacing space between the door exterior panel 11 and the door sheet metal 12. In this way, the connector 13 can avoid the door sheet metal 12 to maintain its integrity, and is not limited by the spacing distance between the door exterior panel 11 and the door sheet metal 12, so as to achieve the connection between the door sheet metal 12 and the door exterior panel 11.

[0054] According to the vehicle door assembly 10 of the embodiment of the present application, on the basis of ensuring the integrity of the vehicle door exterior panel 11 and the vehicle door sheet metal 12, the first plate 131 is fixed to the vehicle door exterior panel 11, and the second plate 132 and the third plate 133 are located outside the space between the vehicle door sheet metal 12 and the vehicle door exterior panel 11, so as not to be limited by the shape of the vehicle door exterior panel 11. Therefore, the connecting member 13 is suitable for limiting the vehicle door sheet metal 12 along the thickness direction of the vehicle door sheet metal 12 when there is insufficient space between the vehicle door sheet metal 12 and the vehicle door exterior panel 11, so as to avoid the phenomenon that the vehicle door exterior panel 11 is lifted or separated from the vehicle door sheet metal 12, and prevent the problem of uneven gap and weak connection strength of the vehicle door assembly 10 from occurring.

[0055] Furthermore, a side of the third plate 133 opposite to the first plate 131 is configured as a plane suitable for pushing the door sheet metal 12 , and a side thereof facing away from the first plate 131 is provided with an arc-shaped guide portion 1331 .

[0056] Among them, the door sheet metal 12 and the door exterior panel 11 are assembled along their own thickness direction; therefore, in the process of the door sheet metal 12 being assembled to the limiting groove a, the third plate 133 located on the side of the limiting groove a away from the door exterior panel 11 will first contact the door sheet metal 12, so that in the process of the door sheet metal 12 moving toward the door exterior panel 11, it is deformed by the push of the door sheet metal 12, and then pushes the end where the second plate 132 and the third plate 133 are connected to flip relative to the end where the second plate 132 and the first plate 131 are connected to elastically deform away from the door sheet metal 12.

[0057] Of course, the arc-shaped guide portion 1331 can be made of any elastic material such as plastic, metal, etc. to provide good elasticity and wear resistance, and produce a certain deformation when subjected to external force; the arc-shaped guide portion 1331 can be constructed as a semicircular, elliptical or other arc-shaped structure with a certain inclination slope.

[0058] Next, continue to refer to Figure 2 , the above process is described in detail with a specific example.

[0059] In some examples, continue to refer to Figure 2 As shown, the arc-shaped guide portion 1331 is configured as an arc-shaped plane.

[0060] It is worth noting that, in the assembly process of the door sheet metal 12 and the door exterior panel 11, in order to accurately match the door sheet metal 12 and the door exterior panel 11, mutually matching positioning pins 112 and positioning holes are usually formed on the door exterior panel 11 and the door sheet metal 12; for example, Figure 4 and Figure 5As shown, a plurality of positioning pins 112 are constructed in the door exterior panel 11 at the lower edge of the door assembly 10. These positioning pins 112 and positioning holes extend along the installation direction (i.e., thickness direction) of the door sheet metal 12 and the door exterior panel 11, and restrict the assembly direction of the door sheet metal 12 and the door exterior panel 11 during assembly, so that the door sheet metal 12 and the door exterior panel 11 can only be matched along their own thickness direction.

[0061] Therefore, during assembly, it is necessary to first position the door exterior panel 11 relative to the door sheet metal 12 through the positioning pins 112, and then press the door sheet metal 12 and the door exterior panel 11 hard to bring the two close together and ensure that the positioning pins 112 in each area form a pin fit with the positioning holes, thereby completing the preliminary positioning between the door exterior panel 11 and the door sheet metal 12.

[0062] In this example, due to the lack of space between the door trim panel 11 and the door sheet metal 12 at the lower edge area, no positioning pin 112 is provided at the lower edge area of ​​the door trim panel 11. During the initial positioning, no pressure is applied to the area, and the door assembly 10 is provided with the connector 13 in the aforementioned embodiment. At this time, the position of the door sheet metal 12 can be referred to as Figure 2 In the dotted line portion shown in , the door sheet metal 12 is pushed against the side of the third plate 133 away from the first plate 131 , and the side is constructed with the aforementioned arc-shaped guide portion 1331 , that is, the arc surface in this example.

[0063] Then, the user can apply a compressive force to the lower edge area of ​​the door sheet metal 12 and the door exterior panel 11; at this time, the lower edge of the door sheet metal 12 squeezes the arc guide portion 1331, and then gradually slides along the arc surface formed by the arc guide portion 1331 to the end of the third plate 133 away from the second plate 132, and is inserted into the limit groove a to complete the assembly. In this process, when the arc guide portion 1331 is pushed by the door sheet metal 12, the force F generated by the door sheet metal 12 will form two components in the horizontal direction and the vertical direction, namely Figure 2 F1 and F2 are shown in FIG. The direction of the force component F2 acting on the third plate 133 in the vertical direction is perpendicular to the thickness direction of the door sheet metal 12. The third plate 133 contacts the door sheet metal 12 through the arc-shaped guide portion 1331 thereon. Since the arc-shaped guide portion 1331 has a certain elasticity and an inclined slope, when the door sheet metal 12 applies pressure, this pressure will be distributed along the arc surface and generate a downward force component, namely, force component F2. This force component F2 acts on the third plate 133 and tends to bend it downward. Moreover, since the third plate 133 is connected to the first plate 131 through the second plate 132, this downward bending tendency will actually be converted into a flipping action of the end of the second plate 132 connected to the third plate 133 relative to the end of the second plate 132 connected to the first plate 131.

[0064] In detail, the third plate 133 is acted upon by the force component F2, so that it tries to move downward. However, since the third plate 133 is integrally connected with the second plate 132 and has a certain rigidity, this downward movement is converted into a flip around the connection point between the second plate 132 and the first plate 131. This flip causes the end of the second plate 132 connected with the third plate 133 to move toward the side away from the door sheet metal 12, thereby providing space for the door sheet metal 12 to enter the limiting groove a defined by the first plate 131 and the third plate 133. As the door sheet metal 12 continues to slide along the arc-shaped guide portion 1331 and finally gets stuck in the limiting groove a, the effect of the force component F2 gradually decreases. Finally, based on the elastic recovery ability of the connector 13, when the door sheet metal 12 slides to release the push against the arc-shaped guide portion 1331, the second plate 132 and the third plate 133 rebound and return to their original positions, thereby limiting the door sheet metal 12 in the limiting groove a and tightening the door sheet metal 12.

[0065] Accordingly, after the assembly is completed, along the thickness direction of the door sheet metal 12, the arc-shaped guide part 1331 and the projection of the door sheet metal 12 at least partially overlap; thus, when the door sheet metal 12 is assembled with the door exterior panel 11, before the door sheet metal 12 enters the limiting groove a, the edge of the door sheet metal 12 will contact the arc-shaped guide part 1331, and the end of the second plate 132 connected to the third plate 133 will be flipped relative to the end of the second plate 132 connected to the first plate 131 by pushing the arc-shaped guide part 1331. In addition, the distance between the arc-shaped guide part 1331 and the first plate 131 gradually decreases in the direction away from the second plate 132, so as to form an arc-shaped surface with an inclined slope; thus, the arc-shaped surface can guide the door sheet metal 12 in contact therewith to slide along the arc-shaped surface toward the edge of the third plate 133 away from the second plate 132, and finally enter the limiting groove a.

[0066] It can be understood that the arc-shaped guide portion 1331 can decompose the force of the door sheet metal 12 on the connecting member 13, so that when the door sheet metal 12 is assembled into the limiting groove a, the end at which the second plate 132 and the third plate 133 are connected is pushed to flip relative to the end at which the second plate 132 and the first plate 131 are connected, thereby avoiding the movement of the door sheet metal 12 toward the door exterior panel 11, and finally the door sheet metal 12 is clamped into the limiting groove a for limiting. In this installation method, the user only needs to press the door exterior panel 11 or the door sheet metal 12. The process is simple and convenient, and can reduce the difficulty of installation.

[0067] Further references Figure 3As shown, a side of the third plate 133 facing the door sheet metal 12 is configured with a plurality of ribs 1332 , and the ribs 1332 extend toward the door sheet metal 12 , so that a side of the ribs 1332 facing the door sheet metal 12 is suitable for pushing against the door sheet metal 12 .

[0068] In this way, the contact area between the third plate 133 and the door sheet metal 12 can be reduced by the ribs 1332 pushing against the door sheet metal 12, so that the direct contact area between the third plate 133 and the door sheet metal 12 is smaller, and the probability of poor flatness on a smaller area is also lower. Therefore, the probability of poor flatness on the side of the third plate 133 that contacts the door sheet metal 12 during processing becomes smaller, thereby reducing the probability of poor matching accuracy due to the uneven contact surface. In addition, an assembly gap of about 1 mm can be left between the ribs 1332 and the door sheet metal 12 to prevent the occurrence of assembly failure due to manufacturing errors.

[0069] In some examples, continue to refer to Figure 2 As shown, the arc-shaped guide portion 1331 is constructed as an arc surface, and its equivalent circle radius is 5 mm to 7 mm.

[0070] Exemplarily, the equivalent circle radius is 5 mm, 6 mm, 7 mm, etc.

[0071] For example, the equivalent circle radius of the arc-shaped guide portion 1331 is 5 mm, thereby ensuring that after the vehicle door sheet metal 12 contacts the arc-shaped guide portion 1331, the arc-shaped guide portion 1331 can provide a sufficient sliding distance for the end of the vehicle door sheet metal 12 and form a component force in the vertical direction, so that the connecting member 13 can be fully bent when subjected to force.

[0072] In some preferred examples, the equivalent circle radius of the arc-shaped guide portion 1331 is 7 mm, so that when the user presses the door sheet metal 12, an appropriate component force along the vertical direction is generated on the arc-shaped guide portion 1331; this can avoid the situation where the vertical component force is too small due to the equivalent circle radius of the arc-shaped guide portion 1331 being too large, which makes it more difficult for the user to press the door sheet metal 12 and the door exterior panel 11.

[0073] Furthermore, the flip angle of the second plate 132 is not less than 5°.

[0074] For example, continue to refer to Figure 2As shown, the equivalent circle radius of the arc-shaped guide portion 1331 is 7 mm, and the corresponding flip angle of the second plate 132 is exactly 5°; wherein, the second plate 132 flips under the push of the door sheet metal 12, and after the door sheet metal 12 is inserted into the limiting groove a, it rebounds 5° to restore the initial state. In this way, after the second plate 132 rebounds, the overlapping part of the third plate 133 and the door sheet metal 12 along the thickness direction of the door sheet metal 12 can form a sufficient limiting effect on the door sheet metal 12; that is, the larger the flip angle of the second plate 132, the larger the overlapping area of ​​the third plate 133 and the door sheet metal 12 in the thickness direction of the door sheet metal 12.

[0075] Therefore, the flipping angle of the second plate 132 can be a larger angle such as 6°, 7°, etc., so as to increase the overlapping area of ​​the third plate 133 and the door sheet metal 12 in the thickness direction of the door sheet metal 12 and further improve the limiting effect.

[0076] Continue to refer Figure 2 In a corresponding example, the edge area of ​​the door exterior panel 11 is provided with a first flange plate 113, and one end of the second plate 132 adjacent to the first plate 131 is provided with a protrusion 1321, and the protrusion 1321 is fitted with the first flange plate 113, so that the other part of the second plate 132 is separated from the first flange plate 113. In this way, the connecting member 13 can be arranged between the first flange plate 113 and the door sheet metal 12, and the spacing space between the second plate 132 and the first flange plate 113 formed by the protrusion 1321 can achieve avoidance of the flipping action of the second plate 132.

[0077] In some examples, the orthographic projection contour of the connecting member 13 toward the first flange plate 113 is located within the contour range of the first flange plate 113; specifically, the edge of the door exterior panel 11 extends beyond the edge of the door sheet metal 12, and the door exterior panel 11 bends and extends the first flange plate 113 toward the door sheet metal 12, and the first flange plate 113 is located in the extension direction of the edge of the door sheet metal 12 to cover the edge of the door sheet metal 12. Figure 3 and Figure 6 As shown, the door exterior panel 11 is further configured with a second flange plate 114 at the edge of the door sheet metal 12 , and the first flange plate 113 and the second flange plate 114 are folded along the edge of the door exterior panel 11 , thereby extending to the shielding connector 13 .

[0078] It is understandable that, through the folding structure of the first flange plate 113 and the second flange plate 114, the connecting member 13 is confined between the first flange plate 113 and the edge of the door sheet metal 12, so that the connecting member 13 is hidden in the appearance surface of the door assembly 10, and the user will not directly see the connecting member when observing the door, thereby not affecting the overall appearance of the door assembly 10. At the same time, the first flange plate 113 and the second flange plate 114 are located on the outside of the connecting member 13, which can form a protective effect on the connecting member.

[0079] In more detail, the gap between the second plate 132 and the first flange plate 113 is 2 mm to 5 mm.

[0080] Exemplarily, the gap between the two can be 2mm, 3mm, 4mm, 5mm, etc.

[0081] For example, the gap between the second plate 132 and the first flange plate 113 is 2 mm; accordingly, the gap between the second plate 132 and the first flange plate 113 can just avoid the flipping action of the second plate 132 to meet the envelope space required when the second plate 132 flips.

[0082] For another example, the gap between the second plate 132 and the first flange plate 113 is 5 mm, so that the distance between the first flange plate 113 and the second plate 132 can be maintained, thereby ensuring that the vertical position of the first flange plate 113 is not too low, causing interference with other decorative panels of the vehicle while avoiding the flipping action of the second plate 132.

[0083] Moreover, after the door sheet metal 12 enters the limiting groove a, the distance between the edge of the door sheet metal 12 and the bottom wall of the limiting groove a (ie, the distance between the second plate 132 and the lower edge of the door sheet metal 12) is 1 mm to 3 mm.

[0084] Exemplarily, the distance between the edge of the door sheet metal 12 and the bottom wall of the limiting groove a can be 1 mm, 2 mm, 3 mm, etc.

[0085] For example, the distance between the edge of the door sheet metal 12 and the bottom wall of the limiting groove a is 1 mm, so as to ensure that after the door sheet metal 12 enters the limiting groove a, its lower edge can leave a certain matching surplus with the second plate 132, thereby preventing interference between the lower edge of the door sheet metal 12 and the second plate 132 after the door sheet metal 12 is assembled into the limiting groove a due to manufacturing errors.

[0086] For another example, the distance between the edge of the door sheet metal 12 and the bottom wall of the limiting groove a is 3 mm, to ensure that the lower edge of the door sheet metal 12 is located in the limiting groove, and the door sheet metal 12 will not be unable to be inserted into the limiting groove a due to the large distance between the door sheet metal 12 and the second plate 132.

[0087] That is to say, based on the elastic connection structure between the second plate 132 and the third plate 133, the sliding of the door sheet metal 12 pushes the arc-shaped guide portion 1331 so that the second plate 132 can be flipped relative to the connection point between it and the first plate 131; and, based on the sufficient gaps reserved between the second plate 132 and the first flange plate 113 and between the door sheet metal 12 and the second plate 132, it can be ensured that the second plate 132 has sufficient envelope space when flipping (that is, it prevents the door sheet metal 12 from interfering with the second plate 132 during the assembly process), thereby fully avoiding the flipping of the second plate 132 and maintaining the flipping angle of the second plate 132 and the third plate 133 in the connecting member 13 relative to the first plate 131 to be no less than 5°.

[0088] It can be understood that by constructing the protrusion 1321 and other avoidance structures, it can be ensured that the second plate 132 has a sufficient flipping angle, thereby ensuring that during the installation of the door sheet metal 12 and the door exterior panel 11, the connecting member 13 can avoid the movement trajectory of the door sheet metal 12 to realize the action process of the door sheet metal 12 being stuck in the limit groove a.

[0089] In some embodiments, reference Figure 5-Figure 6 As shown, the door exterior panel 11 further has a positioning protrusion 1141 , and the edge of the first plate 131 is configured with a positioning notch 1311 , and the positioning protrusion 1141 and the positioning notch 1311 are pushed against each other to limit the position.

[0090] Specifically, the first plate 131 is disposed on the mounting surface and is generally constructed as a rectangular plate, and the second flange plate 114 extends a positioning protrusion 1141 toward the inside of the vehicle door exterior panel 11. A positioning notch 1311 is formed at one edge of the first plate 131 that matches the second flange plate 114. After the positioning protrusion is pushed against the positioning notch 1311, the relative position between the first plate 131 and the vehicle door exterior panel 11 can be determined.

[0091] Exemplary, reference Figure 6 As shown, the positioning protrusion 1141 includes a first protrusion 11411 and a second protrusion 11412 extending in a direction away from the second flange plate 114, and the first protrusion 11411 and the second protrusion 11412 are arranged side by side. The positioning notch 1311 is configured in the connector 13 to fit with the side edge of the second flange plate 114; wherein the two side walls of the positioning notch 1311 and the second flange plate 114 are respectively pushed against the first protrusion 11411 and the second protrusion 11412 to form a positioning; and the ends of the first protrusion 11411 and the second protrusion 11412 are pushed against the bottom of the positioning notch 1311 to form a positioning.

[0092] It can be understood that the connector 13 is fixedly connected to the door exterior panel 11 through the first plate 131, and the connector 13 can be quickly positioned to the edge of the door exterior panel 11, i.e., the preset installation position, through the positioning protrusion 1141 and the positioning notch 1311, thereby improving the positioning and assembly efficiency.

[0093] In addition, the first plate 131 is connected to the door exterior panel 11 by welding. In order to ensure that the pull-off force requirement of 120N is met after welding, a parallelogram welding groove 1312 with an area of ​​at least 15mm x 17mm is formed in the central area of ​​the first plate 131, and ultrasonic welding is used to achieve welding. After testing, such a welding method can meet the pull-off force requirement of 120N.

[0094] The vehicle according to the embodiment of the present application is provided with the door assembly 10 in the above embodiment. Figure 7-Figure 8 As shown, the door assembly 10 is a rear door, in which the transition area between the door exterior panel 11 and peripheral parts such as wheel arches is constructed to be thinner. In order to meet the assembly requirements, a connecting member 13 is provided at the rear end of the rear door to provide a limit for the door sheet metal 12 and the door exterior panel 11 in this area, so as to improve the connection strength of this area while maintaining the visual effect of the appearance.
