[0023] The present application proposes an outer beltline seal assembly.

[0024] 1 to 9 , in an embodiment of the present application, the outer belt line seal assembly includes a door assembly 100, a mounting bracket 200, and an outer belt line seal module 300. The mounting bracket 200 is connected to the door assembly 100 and is located inside a joint corner at the end of the door assembly 100. The outer belt line seal module 300 includes an outer belt line seal joint corner 30 and an outer belt line seal insert 40. The outer belt line seal insert 40 is fixedly connected to the outer belt line seal joint corner 30 and is used to be fitted and fixed to the mounting bracket 200. In this configuration, the fitting and fixing of the outer belt line seal insert 40 to the mounting bracket 200 provides an effective fixing point for the assembly of the outer belt line seal joint corner 30 and can improve the connection strength between the outer belt line seal joint corner 30 and the door assembly 100, thereby further improving the assembly stability and efficiency of the outer belt line seal joint corner 30.

[0025] Specifically, the mounting bracket 200 can be fixedly connected to the door assembly 100 by methods such as spot welding, insertion, or fitting, which ensures that the mounting bracket 200 is firmly attached to the door assembly 100 and provides a mounting fixing point for secure assembly of the outer belt line seal joint corner 30, facilitating the outer belt line seal joint corner 30 to be quickly and securely attached to the mounting bracket 200 by the outer belt line seal insert 40, thereby realizing secure assembly of the outer belt line seal joint corner 30 and advantageously improving the assembly stability and efficiency of the outer belt line seal joint corner 30.

[0026] Here, the mounting bracket 200 is located inside the end joint corner of the door assembly 100, which is specifically the upper end away from the point where the door assembly 100 is hinged to the vehicle body, and thus can provide a mounting and fixing point for the outer belt line seal joint corner 30 of the outer belt line seal module 300, facilitating the connection and fixing between the outer belt line seal joint corner 30 and the door assembly 100.

[0027] Meanwhile, the mounting bracket 200 is located inside the door assembly 100, i.e., the mounting bracket 200 is located on the side of the door assembly 100 facing the vehicle body, so that the outer belt line seal joint corner 30 can be in close contact with the vehicle body and further act as a seal, improving the sealing performance of the vehicle, and ensuring that the outer belt line seal joint corner 30 is shielded and hidden by the door assembly 100, reducing the visible area of ​​the outer belt line seal joint corner 30 and improving the aesthetics of the vehicle.

[0028] The outer belt line seal joint corner 30 and the outer belt line seal insert 40 have an integral structure and can be connected as a whole by methods such as concave-convex fitting, integral molding, or fastening. In this way, the outer belt line seal insert 40 can support the outer belt line seal joint corner 30 and prevent excessive deformation of the outer belt line seal joint corner 30. Meanwhile, the outer belt line seal insert 40 is fitted and fixed to the mounting bracket 200 and can be connected by methods such as reverse hooking or deformation pressing, which effectively prevents the outer belt line seal joint corner 30 from coming off the mounting bracket 200 and causing the seal to fail.

[0029] The technical solution of the present application employs a fitting fastening between the mounting bracket 200 and the outer belt line seal insert 40, which provides an effective fixing point for the assembly of the outer belt line seal joint corner 30, improves the connection strength between the outer belt line seal joint corner 30 and the door assembly 100, and further improves the assembly stability and assembly efficiency of the outer belt line seal joint corner 30. Here, the outer belt line seal insert 40 is fixedly connected to the outer belt line seal joint corner 30, effectively preventing excessive deformation of the outer belt line seal joint corner 30 and ensuring that the outer belt line seal joint corner 30 is securely assembled to the door assembly 100. Meanwhile, the mounting bracket 200 is fixed to the inside of the end joint corner of the door assembly 100, ensuring that the outer belt line seal joint corner 30 is assembled to the door assembly 100 by fastening the outer belt line seal insert 40 to the mounting bracket 200. When the door assembly 100 is applied to a vehicle, the outer belt line seal joint corner 30 is concealed and the vehicle is sealed, thereby improving the aesthetics and sealing performance of the vehicle.

[0030] 4 to 7, in one embodiment, the outer belt line seal joint corner 30 includes a joint corner body 31 and a clamping portion 32 connected to one side of the joint corner body 31, the clamping portion 32 having a clamping groove 321 opening downward, the outer belt line seal insert 40 being at least partially fitted into the groove wall of the clamping groove 321, and the mounting bracket 200 being inserted into the clamping groove 321 and fitted and fixed to the outer belt line seal insert 40. As can be seen, the outer belt line seal joint corner 30 can be inserted from top to bottom along the door assembly 100, with the top end of the mounting bracket 200 fitting into the clamping groove 321, and the outer belt line seal insert 40 being fitted and fixed to the mounting bracket 200, thereby completely restricting the degree of freedom of the outer belt line seal joint corner 30 and ensuring reliable assembly of the outer belt line seal joint corner 30.

[0031] The provision of the clamping groove 321 can limit the effective assembly range of the mounting bracket 200, ensure that the mounting bracket 200 is placed within the clamping groove 321 during assembly, and further enable the mounting bracket 200 to be quickly fitted and fixed to the outer belt line seal insert 40, thereby improving the assembly efficiency of the outer belt line seal joint corner 30.

[0032] At least a portion of the outer belt line seal insert 40 is fitted into the groove wall of the clamping groove 321, which may be the groove side wall or the groove bottom wall. Fitting a portion of the outer belt line seal insert 40 into the groove wall of the clamping groove 321 is advantageous to ensuring a secure connection between the outer belt line seal insert 40 and the clamping portion 32, and at this time, the remaining portion of the outer belt line seal insert 40 is exposed from the groove wall of the clamping groove 321 and can be fitted with the mounting bracket 200 inserted into the clamping groove 321, thereby ensuring a secure assembly of the outer belt line seal joint corner 30 and the door assembly 100.

[0033] 5 and 6, in one embodiment, the outer belt line seal insert 40 includes a first fitting portion 41 and a fitting portion 43 provided on the first fitting portion 41, the first fitting portion 41 is fixed to one groove side wall of the clamping groove 321, the fitting portion 43 protrudes from the first fitting portion 41 and extends toward the other groove side wall of the clamping groove 321, and the mounting bracket 200 is provided with a fitting hole 21 corresponding to the fitting portion 43. As can be understood, when the mounting bracket 200 moves toward the groove bottom wall of the clamping groove 321, the mounting bracket 200 protrudes through its own fitting hole 21. The outer belt line seal insert 40 is fixedly fitted into the provided fitting portion 43, and further engages with the specific structure of the clamping groove 321, effectively restricting the movement of the mounting bracket 200 in the direction perpendicular to the groove bottom wall and the direction perpendicular to the groove side wall; in other words, restricting the movement of the outer belt line seal joint corner 30 relative to the mounting bracket 200, thereby improving the convenience and stability of the connection between the outer belt line seal insert 40 and the mounting bracket 200, and further improving the assembly efficiency and reliability of the outer belt line seal joint corner 30.

[0034] The first fitting portion 41 and the clamping portion 32 have an integral structure and can be connected by methods such as fitting, adhesive bonding, or integral molding, and the fitting portion 43 is connected laterally to the first fitting portion 41 and may be directly fixedly connected to the first fitting portion 41 or may be connected via an intermediary member to facilitate limited inter-engagement between the fitting portion 43 and the fitting hole 21. However, in other embodiments, the fitting hole 21 may be opened in the first fitting portion 41, and the fitting portion 43 may be provided on the mounting bracket 200.

[0035] Specifically, in one embodiment, a through hole 411 is formed in the first mounting portion 41, and a connecting portion 42 is fixed to the hole wall of the through hole 411. The connecting portion 42 is arranged parallel to the first mounting portion 41 and extends away from the mounting bracket 200, and the mating portion 43 is laterally connected to the connecting portion 42. Thus, after the outer belt line seal joint corner 30 is inserted into the mounting bracket 200 and the mating portion 43 abuts against the mounting bracket 200, a force can be continuously applied to the outer belt line seal joint corner 30. At this time, the connecting portion 42 is deformed under the force, and the mating portion 43 always abuts against the mounting bracket 200 and moves relative to the mounting bracket 200 until it engages with the mating hole 21.

[0036] A plurality of through holes 411 can be provided along the extension direction of the joint corner body 31, and in this case, each through hole 411 has a connection portion 42 connected to a mating portion 43, and the mounting bracket 200 has a mating hole 21 corresponding to each mating portion 43. In this way, it is possible to increase the number of attachment points to the mounting bracket 200 and effectively prevent the outer belt line seal insert 40 from rotating relative to the mounting bracket 200, greatly improving the strength and stability of the connection between the outer belt line seal insert 40 and the mounting bracket 200.

[0037] The connecting portion 42 is arranged parallel to the first fitting portion 41, and thus the fitting portion 43 is connected laterally to the connecting portion 42 and can extend toward the other side wall of the clamping groove 321. When inserted into the mounting bracket 200, the fitting portion 43 serves as a guide, allowing the fitting portion 43 to be quickly and accurately engaged with the fitting hole 21, thereby improving the assembly efficiency of the outer belt line seal insert 40 and the mounting bracket 200. The connecting portion 42 extends in a direction away from the mounting bracket 200. As can be seen, the provision of the through-hole 411 not only reduces the weight of the outer belt line seal insert 40, but also In addition, it is possible to provide an escape space for deformation of the connecting portion 42, where the through hole 411 includes a first hole wall and a second hole wall arranged opposite each other, one end of the connecting portion 42 being connected to the first hole wall and a gap being secured between the other end of the connecting portion 42 and the second hole wall. When arranged in this manner, when the connecting portion 42 is subjected to a force, it bends and deforms into the through hole 411, allowing the mounting bracket 200 to move into the clamping groove 321. Furthermore, when the fitting portion 43 is aligned with the fitting hole 21 of the mounting bracket 200, the connecting portion 42 returns to its original state, allowing the fitting portion 43 to be inserted into the fitting hole 21 and ensuring a secure engagement between the fitting portion 43 and the fitting hole 21.

[0038] More specifically, in one embodiment, the connecting portion 42 includes a guide segment 421 and a stopper segment 422, and the surface of the other sidewall of the guide segment 421 facing the clamping groove 321 is a guide arc surface 423. The fitting portion 43 is provided at the connection between the guide segment 421 and the stopper segment 422, and the surface of the fitting portion 43 facing the guide segment 421 smoothly transitions to the guide arc surface 423, thereby serving as a guide. The provision of the guide arc surface 423 allows the mounting bracket 200 to move along the guide arc surface 423 relative to the fitting portion 43, which is advantageous for quickly locating the position of the fitting portion 43. The surface of the mating portion 43 facing the guide segment 421 smoothly transitions into the guide arc surface 423, which effectively prevents the mounting bracket 200 from getting stuck at the connection point between the mating portion 43 and the guide segment 421. This is favorable for quick engagement between the mating hole 21 and the mating portion 43, improving assembly efficiency. It also serves as a position limiter. When the stopper segment 422 is installed, when the mating portion 43 and the mating hole 21 engage with each other, the stopper segment 422 abuts against the edge of the mating hole 21, and the mating portion 43 abuts against the wall of the mating hole 21, effectively restricting the movement of the outer belt line seal joint corner 30 relative to the mounting bracket 200.

[0039] The surface of the guide segment 421 facing the other groove side wall of the clamping groove 321 is a guide arc surface 423, and this guide arc surface 423 protrudes in a direction away from the other groove side wall of the clamping groove 321. Therefore, in order to avoid the risk of structural fracture due to the guide segment 421 being too thin, the surface of the guide segment 421 away from the other groove side wall of the clamping groove 321 is protruded to serve the role of thickening.

[0040] In one embodiment, an escape hole 322 is opened in one side wall of the clamping groove 321 corresponding to the through hole 411, and the escape hole 322 is used for deformation of the connecting portion 42. In this way, an escape space can be provided, and the connecting portion 42 can be reliably deformed by the pressing and supporting action of the mounting bracket 200, and further, if the overall structure of the clamping portion 32 is not affected, manufacturing costs can be reduced.

[0041] Referring to FIG. 6 , in one embodiment, the outer belt line seal insert 40 further includes a second fitting portion 44, which is bent and connected to the first fitting portion 41 and fixedly connected to the other side wall of the clamping groove 321. The mounting bracket 200 is located between the first fitting portion 41 and the second fitting portion 44. As can be seen, the outer belt line seal insert 40 is arranged along the groove wall of the clamping groove 321, which can increase the effective contact area and improve the tightness of the connection between the outer belt line seal insert 40 and the clamping portion 32. Furthermore, the mounting bracket 200 can be restricted between the first fitting portion 41 and the second fitting portion 44, which can prevent the mounting bracket 200 from acting on the clamping portion 32 and causing excessive deformation of the clamping portion 32 or the mounting bracket 200 to come off the clamping portion 32. This is advantageous for improving the reliability of the assembly between the outer belt line seal joint corner 30 and the mounting bracket 200.

[0042] The two opposing surfaces of the first and second fitting portions 41 and 44 are arranged to gradually widen in a direction away from the bottom wall of the clamping groove 321, thereby guiding the mounting bracket 200 to be inserted between the first and second fitting portions 41 and 44, thereby completing the engagement between the fitting hole 21 of the mounting bracket 200 and the fitting portion 43.

[0043] Furthermore, in one embodiment, the second fitting portion 44 is provided with at least one through hole 441, which passes through the first fitting portion 41 and is adjacent to the fitting portion 43, and the clamping portion 32 is provided with a connecting protrusion 323 that fits into the through hole 441. It should be understood that a plurality of fitting portions 43 may be provided, that is, a plurality of through holes 411 may be provided and arranged alternately with the through holes 441, which is advantageous in increasing the effective contact area between the outer belt line seal insert 40 and the clamping portion 32 and improving the connection strength between the outer belt line seal insert 40 and the clamping portion 32, while being advantageous in uniforming force bearing, and improving the connection stability of the outer belt line seal insert 40.

[0044] A plurality of through holes 441 may be provided, and the plurality of through holes 441 may be arranged in an array in the second fitting portion 44, i.e., spaced apart along the direction of extension of the length of the second fitting portion 44, and / or spaced apart along the direction of extension of the width of the second fitting portion 44.

[0045] In one embodiment, an opening 442 is formed in the second mounting portion 44, and the opening 442 is positioned corresponding to the fitting portion 43, which can reduce the weight of the outer belt line seal insert 40 and, when the outer belt line seal insert 40 is manufactured using an integral molding process, facilitate the demolding of the outer belt line seal insert 40.

[0046] 3 to 4 and 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 door assembly 100, the supporting portion 23 is bent and connected to the fixing portion 22, and a fitting hole 21 is provided. It is understood that the fixing portion 22 can be fixed to the door assembly 100 by a connecting method such as spot welding or fastening, and provides an assembly fixing point for the outer belt line seal joint corner 30 of the door assembly 100, and the supporting portion 23 is bent and connected to the fixing portion 22. The specific shape structure formed by the bent connection is compatible with the shape structure of the door assembly 100, and is advantageous in that the support part 23 is arranged as close as possible to the door assembly 100 while being spaced apart from it. This makes it easy for the support part 23 to be inserted between the first insert part 41 and the second insert part 44 and fixed to the insert part 43 of the first insert part 41 through the insert hole 21 of the support part 23, thereby improving the assembly stability of the outer belt line seal joint corner 30, the mounting bracket 200, and the door assembly 100.

[0047] Specifically, in one embodiment, the support portion 23 is longer than the fixing portion 22 in the extension direction of the outer belt line seal joint corner 30, which ensures the connection strength of the mounting bracket 200 and makes it easier to fix the mounting bracket 200. Meanwhile, multiple mating holes 21 can be provided to engage with the mating portion 43, which is advantageous in increasing the effective contact area with the outer belt line seal insert 40, thereby effectively preventing the outer belt line seal insert 40 from tending to rotate relative to the mounting bracket 200 and further improving the assembly stability of the outer belt line seal insert 40 and the mounting bracket 200.

[0048] In one embodiment, the clamping portion 32 and the outer belt line seal insert 40 are injection molded as a single unit. It can be understood that the outer belt line seal insert 40 has a through hole 441, and when the clamping portion 32 and the outer belt line seal insert 40 are injection molded as a single unit, part of the injected material is inserted into the through hole 441 to form the connecting protrusion 323, and the remaining injected material covers the outer belt line seal insert 40. This simplifies the processing and maximizes the effective contact area between the outer belt line seal insert 40 and the clamping portion 32, which is advantageous for improving production efficiency and also for improving the connection strength between the outer belt line seal insert 40 and the clamping portion 32.

[0049] 4 and 5, in one embodiment, the joint corner body 31 has a protruding rib 311 protruding laterally along a direction perpendicular to the door assembly 100, and the protruding rib 311 is used to support the door assembly 100. The bonding between the protruding rib 311 and the door assembly 100 can effectively improve the adhesion between the outer belt line seal joint corner 30 and the door assembly 100, thereby improving the sealing performance of the vehicle.

[0050] In one embodiment, the joint corner body 31 has a semi-closed ring structure, and at least one notch 312 is provided on the inner ring surface of the joint corner body 31. Here, there may be multiple notches 312, and the multiple notches 312 may be arranged at intervals, and the notches 312 may be specifically located at a position where the joint corner body 31 will mainly deform when subjected to force, which is advantageous for ensuring deformation of the joint corner body 31, improving the service life of the joint corner body 31, and ensuring the use effectiveness of the outer belt line sealing joint corner 30. However, in other embodiments, the joint corner body 31 has a closed ring structure.

[0051] 1 to 4 and 9 , in one embodiment, a 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 segment 122, and a first bending segment 123 connected between the inner panel body 121 and the first connecting segment 122. The first connecting segment 122 is bonded to the outer panel 11, and a mounting bracket 200 is fixed to the first connecting segment 122. As can be seen, the first bending segment 123 is connected to the inner panel body 121 and the first connecting segment 122, respectively, and transitions gradually, ensuring a smooth curve of the entire inner panel 12. Furthermore, the first connecting segment 122 can be gradually moved closer to be bonded to the outer panel 11, which can prevent external foreign objects such as water, dust, and sand from entering the door assembly 100 through the gap between the first connecting segment 122 and the outer panel 11, thereby improving the sealing performance of the door assembly 100.

[0052] The mounting bracket 200 is fixed to the first connecting segment 122, i.e., the fixing portion 22 is fixedly connected to the first connecting segment 122, so that the outer belt line seal joint corner 30 can be assembled to the upper end of the door assembly 100 away from the hinged connection point to the vehicle body, and can fit tightly to the vehicle body, playing the role of a seal, further sealing the door assembly 100 and the vehicle body, and improving the sealing performance of the vehicle.

[0053] Furthermore, in one embodiment, the outer panel 11 includes a second connecting segment 112, which has an inner flange 113 along its edge, and which covers the first connecting segment 122 to form an edge cover structure; it can be understood that the first connecting segment 122 gradually approaches and is attached to the second connecting segment 112 on one side, and the second connecting segment 112 has an inner flange 113 along its edge, whereby the inner flange 113 is attached to the other side of the first connecting segment 122 to cover the first connecting segment 122 to form an edge cover structure; at this time, the outer panel 11 and the inner panel 12 are formed as a whole, thereby improving the connection strength and sealing performance of the door molding 100.

[0054] 9 and 13, 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 receiving space for the window glass 500 to move in, and the outer belt line seal module 300 further includes an outer belt line seal body 33 connected to the outer belt line seal joint corner 30, the outer belt line seal body 33 is used to attach to one side of the window glass 500, and the horizontal height of the top end of the outer belt line seal body 33 is lower than the horizontal height of the top end of the outer panel body 111. In this way, it is possible to ensure that the outer belt line seal body 33 is hidden on one side of the outer panel body 111 facing the inner panel body 121, and the aesthetic appearance of the vehicle is effectively ensured.

[0055] Specifically, the outer panel body 111 smoothly transitions to the second connecting segment 112, and the fixing bracket 34 is fixed to the inside. The outer belt line seal body 33 is fixed to the fixing bracket 34 and is provided with a sealing lip, which contacts the window glass 500 to form a complete sealing buffer structure.

[0056] An inner belt line seal module 400 is attached to the inner panel body 121, and the inner belt line seal module 400 is attached to the other side of the window glass 500 to further improve the sealing performance.

[0057] 10 to 12, in one embodiment, the outer belt line seal joint corner 30 includes a joint corner body 31 and a clamping portion 32 connected to one side of the joint corner body 31, and the clamping portion 32 clamps the mounting bracket 200. That is, the outer belt line seal joint corner 30 can be directly inserted and the top end of the mounting bracket 200 can be clamped by the clamping portion 32, which is advantageous to improving the assembly efficiency of the outer belt line seal joint corner 30.

[0058] Furthermore, in one embodiment, the clamping portion 32 is provided with at least one outer belt line seal insert 40 along the extension direction of the joint corner body 31, and the outer belt line seal insert 40 is used to provide a clamping force for clamping the mounting bracket 200. By providing it in this manner, the structural strength of the clamping portion 32 can be improved, and the connection strength and connection stability between the outer belt line seal joint corner 30 and the mounting bracket 200 can also be further improved.

[0059] Specifically, the outer belt line seal insert 40 can be made of a material with elastic properties, such as a metal material, and multiple outer belt line seal inserts 40 are provided, with each outer belt line seal insert 40 arranged at intervals to jointly clamp the mounting bracket 200, increasing the number of high-strength clamping points for the mounting bracket 200 and greatly improving the connection strength and connection stability between the outer belt line seal joint corner 30 and the mounting bracket 200.

[0060] 10 and 12, in one embodiment, the clamping portion 32 has a clamping groove 321 that opens downward, the outer belt line seal insert 40 is disposed along the groove wall of the clamping groove 321, and is provided with a clamping protrusion 32a that protrudes toward the mounting bracket 200. In this manner, the outer belt line seal insert 40 is disposed along the groove wall of the clamping groove 321, and the groove side walls of the clamping groove 321 that correspond to the clamping protrusion 32a of the outer belt line seal insert 40 can be more closely attached to the two opposite sides of the mounting bracket 200, which effectively restricts the movement of the outer belt line seal joint corner 30 in a direction perpendicular to the groove side walls and further improves the assembly stability of the outer belt line seal joint corner 30. Meanwhile, the clamping groove 321 that opens downward is provided by the mounting bracket 200. 21, it can be seen that the groove bottom wall of the clamping groove 321 can abut against the top end of the mounting bracket 200, thereby restricting the movement of the outer belt line seal joint corner 30 in a direction perpendicular to the groove bottom wall. In addition, the two groove side walls of the clamping groove 321 clamp together to further improve the assembly stability of the outer belt line seal joint corner 30. In addition, the mounting bracket 200 can play a positioning role, i.e., by using the mounting bracket 200 as a fixed point on the door assembly 100, the outer belt line seal joint corner 30 can quickly and accurately find the mounting bracket 200 and clamp the mounting bracket 200 using the clamping groove 321, thereby improving the assembly efficiency of the outer belt line seal joint corner 30.

[0061] Specifically, in one embodiment, the clamping portion 32 and the outer belt line seal insert 40 are injection molded as a single unit. Here, as shown in FIG. 6 , the outer belt line seal insert 40 has a plurality of through holes 441 formed therein. When the clamping portion 32 and the outer belt line seal insert 40 are injection molded as a single unit, some of the injected material is inserted into the through holes 441, thereby increasing the effective contact area with the outer belt line seal insert 40 and improving the connection strength between the clamping portion 32 and the outer belt line seal insert 40.

[0062] In one embodiment, the mounting bracket 200 includes a fixed portion 22 and a support portion 23 bent and connected to the fixed portion 22, the fixed portion 22 being fixedly connected to the door assembly 100, and the support portion 23 being fixedly connected to the outer belt line seal joint corner 30. It should be understood that the fixed portion 22 can be fixed to the door assembly 100 by spot welding, fastening, or other connection methods, thereby providing the outer belt line seal joint corner 30 with a fixed point for assembly in the door assembly 100. The specific shape formed by the support portion 23 being bent and connected to the fixed portion 22 matches the shape and structure of the door assembly 100, and is advantageous for the support portion 23 to be as close as possible to but spaced apart from the door assembly 100. The support portion 23 facilitates the outer belt line seal joint corner 30 being inserted and fixed in the clamping groove 321, thereby improving the stability of the assembly of the outer belt line seal joint corner 30 with the mounting bracket 200 and the door assembly 100.

[0063] Specifically, in one embodiment, the support portion 23 is longer in the extension direction of the outer belt line seal joint corner 30 than the fixing portion 22, which ensures the connection strength of the mounting bracket 200 and makes it easier to fix the mounting bracket 200, while being advantageous in increasing the effective contact area with the outer belt line seal joint corner 30 and preventing the outer belt line seal joint corner 30 from flipping over, further improving the assembly stability of the outer belt line seal joint corner 30. In addition, multiple outer belt line seal inserts 40 can act on the support portion 23 together, further improving the connection strength of the outer belt line seal joint corner 30.

[0064] The present application further provides a vehicle, which includes an outer beltline seal assembly, the specific structure of which refers to the above embodiments, and the vehicle adopts all the technical solutions of all the above embodiments, so that it has at least all the beneficial effects of the technical solutions of the above embodiments, which will not be described one by one here.
