DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may also be a centered element. When an element is considered to be "set on" another element, it may be directly set on the other element or there may also be a centered element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0028] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0029] See also Figure 1 The present embodiment provides a vehicle 300, including a vehicle body 301, a side enclosure assembly 200 and a rearview mirror 302. The side enclosure assembly 200 is disposed on the vehicle body 301, and the rearview mirror 302 is connected to the vehicle body 301.

[0030] See also Figure 1 and Figure 2 The side panel assembly 200 includes a side panel sheet metal 201 and a sealing assembly 100. The side panel sheet metal 201 defines a door opening K2. The door opening K2 penetrates the side panel sheet metal 201 along the thickness direction of the side panel sheet metal 201. The sealing assembly 100 is connected to the edge of the side panel sheet metal 201 near the door opening K2.

[0031] In some embodiments, the number of the vehicle door openings K2 is two. The two vehicle door openings K2 are divided into a front door opening K21 and a rear door opening K22. The front door opening K21 and the rear door opening K22 are spaced apart along the length direction of the vehicle 300. The number of the sealing assemblies 100 is two. One sealing assembly 100 is disposed in the front door opening K21 and connected to the side panel metal part 201. The other sealing assembly 100 is disposed in the rear door opening K22 and connected to the side panel metal part 201.

[0032] In some embodiments, see Figure 3 The sealing assembly 100 includes a sealing strip 10 and a plurality of partitions 20. The sealing strip 10 defines a sealing cavity Q1. The plurality of partitions 20 are arranged inside the sealing strip 10 at intervals along the length direction of the sealing strip 10, and divide the sealing cavity Q1 into a plurality of sealing sub-cavities Q2.

[0033] In this way, each sealing sub-cavity Q2 can provide a certain amount of deformation. Compared with a single sealing chamber, multiple mutually spaced sealing sub-cavities Q2 have higher strength and better impact resistance, and can achieve the effect of strengthening the area of ​​the sealing strip 10. After the sealing assembly 100 is used for a long time, the wall of the sealing strip 10 may become weak and attenuated. However, the partition 20 of this embodiment can play a stable supporting role for the sealing strip 10. Even if the wall of the sealing strip 10 is weak, the sealing assembly 100 can still maintain good supporting performance, thereby alleviating the attenuation problem of the sealing assembly 100, thereby improving the overall reliability of the sealing cavity Q1. In addition, when different positions of the sealing strip 10 are subjected to different pressures, multiple mutually independent sealing sub-cavities Q2 can also slow down the phenomenon of inconsistent attenuation caused by different compression amounts of the sealing strip 10, thereby further alleviating the problem of sealing failure caused by inconsistent attenuation, thereby further improving the service life of the sealing assembly 100 and ensuring long-term robustness.

[0034] In some embodiments, the sealing strip 10 is annular and closed, and a plurality of partitions 20 are sequentially spaced along the circumference of the sealing strip 10. In this way, the sealing strip 10 can be stably installed on the edge of the side panel 201 corresponding to the door opening K2.

[0035] In some embodiments, along the height direction of the vehicle 300, the sealing strip 10 is provided with a plurality of partitions 20 at the portion above the window sill line (not shown in the figure) of the vehicle 300. The side doors of some known vehicles are curved from bottom to top toward the interior space of the vehicle. When the glass moves from bottom to top, the glass bends toward the interior space of the vehicle, thereby making the contact with the sealing strip closer, so that during the known glass rising process, the force applied to the portion of the sealing assembly above the window sill line of the vehicle is greater; similarly, when the glass is closed, during the door closing process, the glass will also apply a greater force to the sealing strip from outside to inside. Therefore, during the door opening and closing and the glass 202 lifting and lowering process, the portion of the sealing assembly 100 above the window sill line is the main force-bearing area. In this way, adding partitions 20 in the area of ​​the vehicle 300 where the sealing strip 10 needs to improve the sealing reliability and service life can simultaneously take into account the production cost of the sealing assembly 100 and ensure the sealing reliability.

[0036] In some embodiments, along the extension direction of the sealing strip 10, the spacing between two adjacent partitions 20 is between 150 mm and 200 mm. For example, the spacing can be any one of 150 mm, 160 mm, 170 mm, 180 mm, 190 mm, and 200 mm. The spacing can be adjusted according to the installation environment of the sealing assembly 100, and this embodiment does not specifically limit it. In addition, the spacing between two adjacent partitions 20 refers to the linear distance between two adjacent partitions 20 when the sealing strip 10 is in a straight state.

[0037] In some embodiments, the vehicle 300 further includes a door (not shown in the figure) and a glass 202, and the door is a frameless door. The glass 202 can be raised and lowered on the frameless door. During the opening and closing process of the frameless door, the sealing structure between the door and the side panel 201 requires higher sealing performance. Since the sealing assembly 100 of this embodiment decays more slowly than the existing sealing elements and has higher sealing reliability, it can reduce the probability of sealing failure of the vehicle 300 using the frameless door and improve the reliability of the vehicle 300. In addition, since the sealing reliability between the glass 202 and the sealing assembly 100 is higher, the amount of noise transmitted from the outside of the vehicle 300 to the inside of the vehicle 300 is reduced, thereby improving the sound insulation and noise isolation performance of the vehicle 300, and further optimizing the NVH performance of the vehicle.

[0038] In some embodiments, see Figure 4The sealing assembly 100 further includes a connecting portion 40, which is used to connect the vehicle body 301. The sealing strip 10 includes a first sealing portion 11 and a supporting portion 12. One end of the first sealing portion 11 is connected to one end of the connecting portion 40, and both ends of the supporting portion 12 are respectively connected to the other end of the connecting portion 40 and the other end of the first sealing portion 11. The supporting portion 12, the first sealing portion 11 and the connecting portion 40 are sequentially connected and enclose a sealing cavity Q1, and the edge of the partition 20 is connected to the inner surface of the supporting portion 12, the inner surface of the first sealing portion 11 and the connecting portion 40.

[0039] In some embodiments, see Figure 4 The connecting portion 40 includes a first connecting wall 41, a second connecting wall 42 and a third connecting wall 43. The first connecting wall 41 is connected to the first sealing portion 11 and to the supporting portion 12. The first connecting wall 41 is spaced from the third connecting wall 43, and the second connecting wall 42 is connected between the first connecting wall 41 and the third connecting wall 43. The first connecting wall 41, the second connecting wall 42 and the third connecting wall 43 form a first fixing groove C1. The edge of the side panel 201 corresponding to the door opening K2 extends into the first fixing groove C1 and is connected to the connecting portion 40.

[0040] In some embodiments, see Figure 4 The connecting portion 40 further includes a first abutting strip 45 and a second abutting strip 46. The first abutting strip 45 is disposed on the surface of the third connecting wall 43 facing the first fixing groove C1, and the second abutting strip 46 is disposed on the surface of the first connecting wall 41 facing the first fixing groove C1. The edge of the side panel metal 201 corresponding to the door opening K2 is clamped between the first abutting strip 45 and the second abutting strip 46 to improve the connection reliability between the connecting portion 40 and the side panel metal 201, and improve the installation reliability of the sealing assembly 100. In addition, the first abutting strip 45 and the second abutting strip 46 can also reduce the contact area between the side panel metal 201 and the inner wall of the first fixing groove C1, so as to reduce the vibration transmitted from the side panel metal 201 to the sealing strip 10.

[0041] The number of the first abutting strips 45 and the number of the second abutting strips 46 may be plural.

[0042] In some embodiments, see Figure 4 The connecting portion 40 also includes a U-shaped steel 47, which is embedded in the first connecting wall 41, the second connecting wall 42 and the third connecting wall 43 to improve the structural strength of the connecting portion 40 and ensure a reliable connection between the sealing strip 10 and the side panel 201.

[0043] In some embodiments, the connecting portion 40 further includes a connecting protrusion 44. The connecting protrusion 44 is connected between the first sealing portion 11 and the first connecting wall 41.

[0044] In some embodiments, see Figure 4 The sealing assembly 100 also includes an abutment portion 60. The abutment portion 60 is connected to the second connecting wall 42 and is cantilevered, and a second fixing groove C2 is formed between the abutment portion 60 and the second connecting wall 42. The interior trim panel 203 extends into the second fixing groove C2 and is connected to the abutment portion 60 and the second connecting wall 42. In this way, the installation stability of the sealing assembly 100 on the vehicle 300 can be further improved. In addition, through the sealing cooperation between the abutment portion 60 and the interior trim panel 203, it is possible to prevent external rainwater, dust, etc. from entering the interior of the vehicle body 301 through the gap between the abutment portion 60 and the interior trim panel 203, thereby alleviating the rust of the internal structure of the vehicle body 301, which is beneficial to improving the overall sealing performance of the vehicle 300.

[0045] In some embodiments, see Figure 4 The sealing assembly 100 further includes an abutting protrusion 61. The abutting protrusion 61 is convexly disposed on the inner surface of the abutting portion 60 facing the second fixing groove C2, and abuts against the interior trim panel 203, thereby improving the fixing stability and sealing reliability of the interior trim panel 203.

[0046] In some embodiments, the cross-section of the sealing strip 10 is roughly semi-enclosed, and the cross-section of the partition 20 is roughly semi-enclosed. One end of the semi-enclosed sealing strip 10 is connected to the connecting portion 40, and the other end abuts against the glass 202. This is conducive to the deformation of the sealing strip 10 to improve the sealing effect.

[0047] In some embodiments, see Figure 4 The vehicle 300 further includes an interior trim panel 203. The sealing strip 10 is located on the inner side of the glass 202, and the first sealing portion 11 is in contact with the inner side of the glass 202. The inner side and outer side of the glass 202 refer to the inner and outer spaces in the left-right direction of the vehicle 300. For example, the inner side of the glass 202 located on the left door of the vehicle 300 refers to the right side of the glass 202, and the inner side of the glass 202 located on the right door of the vehicle 300 refers to the left side of the glass 202.

[0048] When the glass 202 is raised and the door is closed, the first sealing portion 11 is in contact with the inner side of the glass 202, so that the gap between the glass 202 and the door frame can be well filled by the first sealing strip 10. Therefore, the first sealing portion 11 cooperates with the glass 202 to ensure the sealing of the glass 202 when the door is closed, thereby preventing external rainwater, dust, etc. from entering the inner side of the glass 202, i.e., the passenger space, through the gap between the glass 202 and the door frame, and at the same time reducing the noise from the external environment in the passenger space, such as wind noise, etc., which is conducive to improving the comfort of the driver and passengers.

[0049] In some embodiments, see Figure 4, the side of the first sealing portion 11 away from the connecting portion 40 is a smooth curved surface, that is, the side of the first sealing portion 11 facing the glass 202 is a smooth curved surface. As a result, the groove feature of the first sealing portion 11 is reduced to simplify the structure of the first sealing portion 11, and reduce the production cost and processing difficulty of the first sealing portion 11. The first sealing portion 11 extends obliquely in the direction away from the center of the glass 202 in the direction toward the outside of the vehicle 300 to increase the projection area of ​​the first sealing portion 11 on the glass 202, thereby increasing the contact area of ​​the first sealing portion 11 pressing the glass 202 and improving the sealing effect between the first sealing portion 11 and the glass 202.

[0050] In some embodiments, see Figure 4 One end of the supporting portion 12 is connected to an end of the first sealing portion 11 close to the glass 202, and the other end of the supporting portion 12 is connected to the first connecting wall 41 of the connecting portion 40, so that a triangular structure can be roughly formed between the first sealing portion 11, the supporting portion 12 and the connecting portion 40, which is beneficial to improving the stability of the sealing strip 10. When the first sealing portion 11 is squeezed by the glass 202, the first sealing portion 11 pushes the supporting portion 12 to deform, and the shape of the sealing cavity Q1 changes accordingly. When the squeezing force acting on the first sealing portion 11 disappears, the supporting portion 12 and the first sealing portion 11 resume deformation, and the sealing cavity Q1 returns to its initial state.

[0051] In some embodiments, the side of the support portion 12 facing away from the sealed cavity Q1 is concave toward the sealed cavity Q1. When the first sealing portion 11 is pressed by the glass 202, the first sealing portion 11 pushes the support portion 12 to bend and deform toward the sealed cavity Q1, which can better avoid the support portion 12 bending away from the sealed cavity Q1 to cause interference.

[0052] In some embodiments, see Figure 4 The vehicle 300 further includes a B-pillar housing 204. The sealing assembly 100 further includes a second sealing portion 50. The B-pillar housing 204 is disposed outside the side panel 201 to shield the side panel 201, thereby improving the overall appearance of the vehicle 300. The B-pillar housing 204 has an assembly portion 51. A buffer 70 is disposed between the assembly portion 51 and the outer side of the side panel 201. The buffer 70 can buffer the impact force between the assembly portion 51 and the side panel 201 to reduce the transmission of vibration and friction noise. An installation groove C3 is defined between the assembly portion 51 and the B-pillar housing 204. The opening of the installation groove C3 faces the glass 202. The second sealing portion 50 is disposed in the installation groove C3. In this way, the installation of the second sealing portion 50 can be better guaranteed. At the same time, the installation of the second sealing portion 50 can make full use of the space in the B-pillar housing 204, and the layout is compact. In addition, the second sealing portion 50 is disposed on a side of the B-pillar housing 204 facing the glass 202 , which helps to reduce the difficulty of matching the second sealing portion 50 with the glass 202 .

[0053] In some embodiments, see Figure 4 The second sealing portion 50 includes an assembly portion 51, a first sealing lip 52, and a second sealing lip 53. The assembly portion 51 is disposed in the mounting groove C3, and the first sealing lip 52 and the second sealing lip 53 are both disposed on the side of the assembly portion 51 facing the glass 202. The fixed end of the first sealing lip 52 is located outside the fixed end of the second sealing lip 53, and the first sealing lip 52 and the second sealing lip 53 extend in a C-shaped direction toward each other from the fixed end of the first sealing lip 52 toward the free end, and the free end of the second sealing lip 53 is located on the side of the first sealing lip 52 away from the assembly portion 51. The outer side surface of the first sealing lip 52 is suitable for fitting with the side surface of the glass 202 facing the B-pillar housing 204, and the outer side surface of the second sealing lip 53 is suitable for fitting with the inner side surface of the glass 202. The C-shaped first sealing lip 52 and the second sealing lip 53 can increase the contact area with the glass 202 to improve the sealing effect. In this way, the gap between the glass 202 and the B-pillar housing 204 can be well filled by the second sealing portion 50, and the sealing strip 10 also forms a sealing match with the glass 202, so that the sealing assembly 100 can form a three-layer seal on the glass 202, which is conducive to further improving the sealing effect of the frameless door. The sealing strip 10 and the second sealing portion 50 are arranged at intervals to avoid interference between the sealing strip 10 and the second sealing portion 50 when they are deformed.

[0054] In some embodiments, see Figure 4 , a plurality of first mating protrusions 13 are provided at intervals on the side of the connection part 40 facing the sealing cavity Q1, and a plurality of second mating protrusions 14 are provided at intervals on the side of the first sealing part 11 facing the sealing cavity Q1. One of the two adjacent side surfaces of the partition part 20 is mated with the plurality of first mating protrusions 13, and the other of the two adjacent side surfaces of the partition part 20 is mated with the plurality of second mating protrusions 14. In this way, the possibility of relative displacement between the partition part 20 and the inner wall of the sealing cavity Q1 can be reduced, thereby improving the connection reliability between the partition part 20 and the sealing strip 10.

[0055] In some embodiments, see Figure 5 and Figure 6 At least part of the partition 20 is a partitioning partition 31, and the two sealed sub-cavities Q2 located on both sides of the partitioning partition 31 are not connected to each other.

[0056] In the portion of the sealing component 100 corresponding to the plurality of spaced-apart partitioning parts 31, since the plurality of sealing sub-cavities Q2 are not interconnected, the sealing reliability can be further enhanced when the sealing component 100 is subjected to pressure, and the attenuation of the sealing strip 10 corresponding to the mutually unconnected sealing sub-cavities Q2 can be delayed, while the buffering effect can be ensured, and the wear phenomenon can be reduced, thereby extending the service life of the sealing component 100.

[0057] In some embodiments, see Figure 5 and Figure 6 At least part of the partition 20 is a connecting partition 32, and the connecting partition 32 is provided with a connecting hole K1, and the two sealed sub-cavities Q2 located on both sides of the connecting partition 32 are connected through the connecting hole K1.

[0058] In the portion of the sealing component 100 corresponding to the plurality of spaced partitioning parts 31, when the sealing component 100 is subjected to pressure, the airflow between two adjacent sealing sub-cavities Q2 can flow mutually, thereby increasing the deformation size generated when each sealing sub-cavity Q2 is subjected to force, and further providing a certain buffering effect under the premise of ensuring a certain sealing reliability. And after the portion is kept in a stressed state, since each sealing sub-cavity Q2 is interconnected, the air pressure of the corresponding portion of the sealing component 100 is balanced, which can ensure the sealing performance of the portion, thereby simultaneously improving the sealing reliability, buffering reliability and impact resistance of the sealing component 100.

[0059] In some cases, please re-attend Figure 2 , the side panel metal part 201 is provided with a top area A1, four corner areas A2 and a window sill area A3 at the edge corresponding to the door opening K2. The top area A1 is located on the upper side of the side panel metal part 201, the four corner areas A2 are located at the four corners of the door opening K2, and the window sill area A3 is located on the side of the door opening K2 close to the B-pillar housing 204 and corresponds to the area at the position of the window sill line. The area of ​​the side panel metal part 201 corresponding to the rearview mirror 302 is the rearview mirror area A4, which is specifically the area on the vehicle body 301 corresponding to the A-pillar (not shown in the figure) where the rearview mirror 302 is installed.

[0060] See also Figure 7 and Figure 8The sealing strip 10 of the sealing assembly 100 includes a top section 15, a bottom section 16, a first side section 17 and a second side section 18. The top section 15 and the bottom section 16 are spaced apart along the height direction of the vehicle 300, and the first side section 17 and the second side section 18 are spaced apart along the front-rear direction of the vehicle 300. The top section 15, the bottom section 16, the first side section 17 and the second side section 18 are sequentially connected and enclosed to form a closed annular structure, so that the sealing strip 10 can be stably installed in the door opening K2 of the vehicle. Among them, the top section 15 is provided with a first reinforcement area B1. At the sealing assembly 100 installed in the front door opening K21, the connection between the top section 15 and the first side section 17 is provided with a second reinforcement area B2; the portion of the first side section 17 corresponding to the window sill line is provided with a third reinforcement area B3. The connection between the top section 15 and the second side section 18 is provided with a fourth reinforcement area B4. At the sealing assembly 100 installed at the rear door opening K22, a second reinforcement area B2 is provided at the connection between the top section 15 and the first side section 17; a second reinforcement area B2 is provided at the connection between the top section 15 and the second side section 18, and a third reinforcement area B3 is provided at the portion of the first side section 17 corresponding to the window sill line. The first reinforcement area B1 corresponds to the top area A1, the second reinforcement area B2 corresponds to the corner area A2, the third reinforcement area B3 corresponds to the window sill line area A3, and the fourth reinforcement area B4 corresponds to the rearview mirror area A4.

[0061] In some embodiments, see Figure 7 and Figure 8 The sealing strip 10 of the sealing assembly 100 has a portion corresponding to the top area A1 that is provided with a connecting partition 32 and at least two partition partitions 31 . The two partition partitions 31 are located at both ends of the top area A1 , and the connecting partition 32 is located between the two partition partitions 31 .

[0062] When the glass 202 of the vehicle door is rising, a certain impact force is generated on the top area A1 of the side panel 201. By setting a connecting partition 32 and at least two partition partitions 31 in the top area A1 corresponding to the sealing strip 10, when the sealing strip 10 is impacted, the multiple sealed sub-cavities Q2 formed by the connecting partition 32 and the partition partition 31 can alleviate the attenuation phenomenon of the sealing strip 10. At the same time, the air in each sealed sub-cavity Q2 can flow to each other through the connecting hole K1 of the connecting partition 32, so that the buffering performance of the part of the sealing strip 10 corresponding to the top area A1 is stronger, so as to improve the passing performance of the glass 202. In this way, the glass 202 can achieve a fast rising and falling switching effect, thereby ensuring the application reliability of the frameless vehicle door. In addition, after the glass 202 is completely closed, the multiple sealing sub-cavities Q2 of the sealing strip 10 corresponding to the top area A1 can achieve air pressure balance through the airflow flow of the connecting hole K1, so that the sealing reaction force of the sealing strip 10 corresponding to each part of the top area A1 is relatively uniform, so as to ensure the sealing performance of the glass 202 in the top area A1.

[0063] Specifically, in this embodiment, two partitioning partitions 31 and a plurality of connecting partitions 32 are provided at the first reinforcement area B1. The number of connecting partitions 32 can be adjusted according to the length of the top section 15. For example, at the top section 15 of the sealing assembly 100 installed at the front door opening K21, the number of connecting partitions 32 of the first reinforcement area B1 is three, and at the top section 15 of the sealing assembly 100 installed at the rear door opening K22, the number of connecting partitions 32 of the first reinforcement area B1 is two.

[0064] In some embodiments, see Figure 7 and Figure 8 The sealing strip 10 of the sealing assembly 100 is provided with a connecting partition 32 and at least two partition partitions 31 at the portion corresponding to the corner area A2. The two partition partitions 31 are located at both ends of the corner area A2, and the connecting partition 32 is located between the two partition partitions 31.

[0065] During the opening and closing process of the door, the door will generate a certain impact force on the corner area A2. By setting a connecting partition 32 and at least two partitioning partitions 31 in the top area A1 corresponding to the sealing strip 10, when the sealing strip 10 is impacted, the multiple sealing sub-cavities Q2 formed by the connecting partition 32 and the partitioning partition 31 can alleviate the attenuation phenomenon of the sealing strip 10. At the same time, the air in each sealing sub-cavity Q2 can flow through the connecting hole K1 of the connecting partition 32, so that the buffering performance of the part of the sealing strip 10 corresponding to the corner area A2 is stronger, so as to improve the closing buffering performance of the door, so as to ensure the reliability of the opening and closing process of the frameless door. In addition, after the door is completely closed, the multiple sealing sub-cavities Q2 of the part of the sealing strip 10 corresponding to the corner area A2 can achieve air pressure balance through the airflow of the connecting hole K1, so that the sealing reaction force of the sealing strip 10 corresponding to the corner area A2 is relatively uniform, so as to ensure the sealing performance of the door in the corner area A2.

[0066] Among them, on the upper side of the door opening K2 along the height direction of the vehicle 300, the corner area A2 is the corner area A2 of the side panel 201 corresponding to the door opening K2 on both sides of the length direction of the vehicle 300.

[0067] In other embodiments, the sealing strip 10 of the sealing assembly 100 may also be provided with a plurality of partitions 20 corresponding to two other corner areas A2 on the lower side of the door opening K2 along the height direction of the vehicle 300 of the side panel 201 .

[0068] Specifically, in this embodiment, the number of partitioning partitions 31 provided in the second reinforcement area B2 can be set to two, and the number of connecting partitions 32 can be set to one, so as to fully ensure the spacing size of the partitions 20 and ensure the sealing effect of the sealing assembly 100 at the second reinforcement area B2.

[0069] In some embodiments, see Figure 7 and Figure 8 The sealing strip 10 of the sealing assembly 100 is provided with at least two spaced-apart partitioning parts 31 in a portion corresponding to the window sill line area A3.

[0070] In this way, the sealing strip 10 is used to partially strengthen the window sill line area A3, so as to alleviate the attenuation problem of the sealing strip 10 in the portion corresponding to the window sill line area A3 (i.e., the third reinforcement area B3), thereby extending the reliability of the sealing strip 10, reducing the sealing failure problem in the window sill line area A3, and further reducing the problems such as water leakage and wind noise caused by sealing failure, so as to improve the user experience. In addition, since the partial attenuation of the sealing strip 10 in the window sill line area A3 is alleviated, the door can adopt a frameless door design, thereby taking into account both the appearance and performance of the vehicle 300.

[0071] Specifically, in this embodiment, the number of the partitioning partitions 31 provided in the third reinforcement area B3 can be set to two, three, four or more.

[0072] In some embodiments, see Figure 7 and Figure 8 The vehicle door opening K2 is a front door opening K21, and the front door opening K21 has a rearview mirror area A4 corresponding to the rearview mirror 302. The portion of the sealing strip 10 of the sealing assembly 100 corresponding to the rearview mirror area A4 is provided with at least two spaced-apart partitioning parts 31.

[0073] In this way, the sealing strip 10 is used to locally reinforce the rearview mirror area A4 to alleviate the attenuation problem of the sealing strip 10 in the portion corresponding to the rearview mirror area A4 (i.e., the fourth reinforcement area B4), thereby extending the reliability of the sealing strip 10 and reducing the sealing failure problem in the rearview mirror area A4, thereby further reducing problems such as water leakage and wind noise caused by sealing failure, and improving user experience.

[0074] Specifically, in this embodiment, the number of the partitioning partitions 31 provided in the fourth reinforcement area B4 can be set to two, three, four or more.

[0075] Furthermore, in this embodiment, at any two adjacent regions among the first reinforcement region B1, the second reinforcement region B2, the third reinforcement region B3 and the fourth reinforcement region B4, the same partition dividing portion 31 may be provided in the sealing assembly 100 to correspond to the two adjacent reinforcement regions.

Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
