[0023] This application proposes an outer belt line seal assembly.

[0024] Referring to FIGS. 1 to 9, in the embodiments 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 the 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. With such an arrangement, the fitting and fixing of the outer belt line seal insert 40 and the mounting bracket 200 provide an effective fixing point for the assembly of the outer belt line seal joint corner 30, improve the connection strength between the outer belt line seal joint corner 30 and the door assembly 100, and further improve the assembly stability and assembly 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 means such as spot welding, insertion, and fitting, ensuring that the mounting bracket 200 is firmly attached to the door assembly 100, providing a mounting and fixing point for the reliable assembly of the outer belt line seal joint corner 30, facilitating the rapid and firm attachment of the outer belt line seal joint corner 30 to the mounting bracket 200 by the outer belt line seal insert 40, realizing the reliable assembly of the outer belt line seal joint corner 30, and being advantageous for improving the assembly stability and assembly efficiency of the outer belt line seal joint corner 30.

[0026] Here, the mounting bracket 200 is located inside the joint corner at the end of the door assembly 100. The joint corner at the end of the door assembly 100 is specifically the upper end away from the hinge connection point of the door assembly 100 to the vehicle body. In this way, a mounting and fixing point can be provided at the outer belt line seal joint corner 30 in the outer belt line seal module 300, facilitating the connection and fixation between the outer belt line seal joint corner 30 and the door assembly 100.

[0027] On the other hand, the mounting bracket 200 is located inside the door assembly 100, that is, the mounting bracket 200 is located on the side facing the vehicle body of the door assembly 100. In this way, the outer belt line seal joint corner 30 can be in close contact with the vehicle body, further playing a sealing role, improving the sealing performance of the vehicle, ensuring that the outer belt line seal joint corner 30 is provided so as to be shielded and hidden by the door assembly 100, reducing the visible area of the outer belt line seal joint corner 30, and improving the aesthetic appearance of the vehicle.

[0028] The outer belt line seal joint corner 30 and the outer belt line seal insert 40 are of an integral structure and can be connected as a whole by means such as concave-convex fitting, integrated molding, and fastening. In this way, the outer belt line seal insert 40 can support the outer belt line seal joint corner 30, preventing excessive deformation of the outer belt line seal joint corner 30. On the other hand, the outer belt line seal insert 40 is fitted and fixed to the mounting bracket 200 and can be connected by means such as reverse hanging and deformation pressing, effectively preventing seal failure caused by the separation of the outer belt line seal joint corner 30 from the mounting bracket 200.

[0029] The technical solution of this application adopts the fitting and fastening between the mounting bracket 200 and the outer belt line seal insert 40, so as to provide an effective fixing point for the assembly of the outer belt line seal joint corner 30, improve the connection strength between the outer belt line seal joint corner 30 and the door assembly 100, and further improve 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. On the other hand, the mounting bracket 200 is fixed inside the joint corner at the end of the door assembly 100, ensuring that the outer belt line seal joint corner 30 can be assembled to the door assembly 100 by the mounting and fastening between the outer belt line seal insert 40 and the mounting bracket 200. When the door assembly 100 is applied to a vehicle, it can realize the installation of hiding the outer belt line seal joint corner 30 and the effect of sealing the vehicle, and further improve the aesthetics and sealing performance of the vehicle.

[0030] Referring to FIGS. 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 has a clamping groove 321 that opens downward. At least a part of the outer belt line seal insert 40 is fitted into the groove wall of the clamping groove 321. The mounting bracket 200 is inserted into the clamping groove 321 and is fitted and fixed to the outer belt line seal insert 40. As can be understood, the outer belt line seal joint corner 30 can be inserted from top to bottom along the door assembly 100. The top end of the mounting bracket 200 is inserted into the clamping groove 321, and further, the outer belt line seal insert 40 can be fitted and fixed to the mounting bracket 200, realizing a complete restriction on the degree of freedom of the outer belt line seal joint corner 30 and meeting the reliable assembly of the outer belt line seal joint corner 30.

[0031] The installation of the clamping groove 321 can limit the effective assembly range of the mounting bracket 200, ensure that the mounting bracket 200 can be inserted into 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 part of the outer belt line seal insert 40 is fitted into the groove wall of the clamping groove 321. The groove wall may be a groove side wall or a groove bottom wall. By fitting a part of the outer belt line seal insert 40 into the groove wall of the clamping groove 321, it is advantageous to ensure a reliable connection between the outer belt line seal insert 40 and the clamping portion 32. At this time, the remaining part 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 that enters the clamping groove 321, thereby realizing a reliable assembly between the outer belt line seal joint corner 30 and the door assembly 100.

[0033] Referring to FIGS. 5 to 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. A fitting hole 21 corresponding to the fitting portion 43 is provided in the mounting bracket 200. As can be understood, in the process of the mounting bracket 200 moving toward the groove bottom wall direction of the clamping groove 321, the mounting bracket 200 is fitted and fixed to the fitting portion 43 protruding through its own fitting hole 21, 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 movement in 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. In this way, the connection convenience and connection stability between the outer belt line seal insert 40 and the mounting bracket 200 can be improved, and further the assembly efficiency and assembly certainty of the outer belt line seal joint corner 30 can be improved.

[0034] The first fitting portion 41 and the clamping portion 32 are of an integral structure, and the connection can be realized by means such as fitting, adhesion, and integral molding. The fitting portion 43 is connected to the first fitting portion 41 in the lateral direction and may be directly fixedly connected to the first fitting portion 41, or may be connected via a relay member to facilitate the mutual engagement restriction 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 is provided on the mounting bracket 200.

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

[0036] A plurality of through holes 411 can be provided along the extending direction of the joint corner body 31. At this time, a connecting portion 42 to which the fitting portion 43 is connected is provided in each through hole 411, and fitting holes 21 corresponding to the fitting portions 43 are provided in the mounting bracket 200. In this way, the number of attachment points to the mounting bracket 200 can be increased, and moreover, the tendency of the outer belt line seal insert 40 to rotate relative to the mounting bracket 200 can be effectively prevented, and the connection strength and connection stability between the outer belt line seal insert 40 and the mounting bracket 200 can be greatly improved.

[0037] The connecting portion 42 is provided in parallel with the first fitting portion 41. In this way, the fitting portion 43 can be connected to the connecting portion 42 in the lateral direction and extend toward the other groove side wall of the clamping groove 321. When inserted into the mounting bracket 200, it serves as a guide to quickly and accurately engage the fitting portion 43 into the fitting hole 21, 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 understood, the installation of the through hole 411 can not only lighten the outer belt line seal insert 40, but also provide a clearance space for the deformation of the connecting portion 42. Here, the through hole 411 includes a first hole wall and a second hole wall provided opposite to each other. One end of the connecting portion 42 is connected to the first hole wall, and a gap is secured between the other end of the connecting portion 42 and the second hole wall. With this arrangement, when the connecting portion 42 receives a force, it can bend and deform into the through hole 411 to move the mounting bracket 200 into the clamping groove 321. Further, 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, inserting the fitting portion 43 into the fitting hole 21 to achieve a reliable 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. The surface of the other groove side wall 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 location between the guide segment 421 and the stopper segment 422. The surface of the fitting portion 43 facing the guide segment 421 smoothly transitions to the guide arc surface 423. With such an arrangement, it can play a guiding role. By providing the guide arc surface 423, the mounting bracket 200 can be moved relative to the fitting portion 43 along the guide arc surface 423, which is advantageous for quickly finding the position of the fitting portion 43. Moreover, the surface of the fitting portion 43 facing the guide segment 421 smoothly transitions to the guide arc surface 423, effectively preventing the mounting bracket 200 from getting stuck at the connection location between the fitting portion 43 and the guide segment 421, which is advantageous for the quick engagement between the fitting hole 21 and the fitting portion 43, improving the assembly efficiency. On the other hand, it can play a role in position limitation. In accordance with the installation of the stopper segment 422, when the fitting portion 43 and the fitting hole 21 are engaged with each other, the stopper segment 422 abuts against the edge of the fitting hole 21, and the fitting portion 43 abuts against the hole wall of the fitting 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 the guide arc surface 423 protrudes in a direction away from the other groove side wall of the clamping groove 321. In order to avoid the occurrence of risks such as structural breakage 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 provided to protrude, playing a role in thickening.

[0040] In one embodiment, a relief hole 322 is formed in one groove sidewall of the clamping groove 321 corresponding to the through hole 411. The relief hole 322 is used for the deformation of the connecting portion 42. In this way, a relief space can be provided, and the connecting portion 42 can be reliably deformed by the supporting action of the mounting bracket 200. Moreover, when the overall structure of the clamping portion 32 is not affected, the manufacturing cost 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. The second fitting portion 44 is bent and connected to the first fitting portion 41 and is fixedly connected to the other groove sidewall 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 understood, the outer belt line seal insert 40 is arranged along the groove wall of the clamping groove 321. In this way, the effective contact area can be increased, the connection adhesion between the outer belt line seal insert 40 and the clamping portion 32 can be improved, and further, the mounting bracket 200 can be restricted between the first fitting portion 41 and the second fitting portion 44, avoiding the mounting bracket 200 acting on the clamping portion 32 to cause excessive deformation of the clamping portion 32 or the mounting bracket 200 detaching from the clamping portion 32, which is advantageous for improving the assembly certainty between the outer belt line seal joint corner 30 and the mounting bracket 200.

[0042] The two surfaces where the first fitting portion 41 and the second fitting portion 44 are provided opposite to each other are provided so as to gradually expand in a direction away from the groove bottom wall of the clamping groove 321, thereby guiding the mounting bracket 200 to be inserted between the first fitting portion 41 and the second fitting portion 44, and thus completing the engaging engagement between the fitting hole 21 of the mounting bracket 200 and the fitting portion 43.

[0043] Furthermore, in one embodiment, at least one through-hole 441 is provided in the second fitting portion 44. The through-hole 441 passes through the first fitting portion 41 and is provided adjacent to the fitting portion 43. A connecting convex portion 323 adapted to the through-hole 441 is provided on the clamping portion 32. As can be understood, 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 for increasing the effective contact area between the outer belt line seal insert 40 and the clamping portion 32, improving the connection strength between the outer belt line seal insert 40 and the clamping portion 32, while being advantageous for the uniformization of force reception 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, that is, they may be provided at intervals along the extending direction of the length of the second fitting portion 44, and / or they may be provided at intervals along the extending direction of the width of the second fitting portion 44.

[0045] In one embodiment, an opening 442 is formed in the second fitting portion 44. The opening 442 is provided corresponding to the fitting portion 43, which can reduce the weight of the outer belt line seal insert 40. Also, when the outer belt line seal insert 40 is manufactured by adopting an integral molding process, it facilitates the demolding of the outer belt line seal insert 40.

[0046] Referring to FIGS. 3 to 4 and FIG. 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. As can be understood, the fixing portion 22 can be fixed to the door assembly 100 by connection methods such as spot welding and fastening, providing an assembly fixing point in the door assembly 100 for the outer belt line seal joint corner 30. The specific shape structure formed by the supporting portion 23 being bent and connected to the fixing portion 22 conforms to the shape structure of the door assembly 100, and it is advantageous that the supporting portion 23 is provided as close as possible and at an interval from the door assembly 100. The supporting portion 23 is inserted between the first fitting portion 41 and the second fitting portion 44, facilitating being fixed to the fitting portion 43 in the first fitting portion 41 through the fitting hole 21 in the supporting portion 23, and 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 supporting portion 23 is longer than the fixing portion 22 in the extending direction of the outer belt line seal joint corner 30, ensuring the connection strength of the mounting bracket 200 and facilitating the fixing of the mounting bracket 200. On the other hand, a plurality of fitting holes 21 for engaging with the fitting portion 43 can be provided, which is advantageous for increasing the effective contact area with the outer belt line seal insert 40. Thereby, effectively preventing the tendency of the outer belt line seal insert 40 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 integrally injection-molded. As can be understood, the outer belt line seal insert 40 is provided with a through hole 441. When the clamping portion 32 and the outer belt line seal insert 40 are integrally injection-molded, a part of the injection material is fitted into the through hole 441 to form the connecting convex portion 323, and the remaining injection material covers the outer belt line seal insert 40. The processing process is simple. When the effective contact area between the outer belt line seal insert 40 and the clamping portion 32 is as large as possible, it is advantageous to improve the production efficiency, and the connection strength between the outer belt line seal insert 40 and the clamping portion 32 can also be improved.
