[0087] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application but not all the embodiments of the present application.

[0088] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be intervening elements. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be intervening elements. When an element is referred to as being "disposed" on another element, it can be directly on the other element or there can be intervening elements. The terms "vertical", "horizontal", "left", "right", and similar terms as used herein are for purposes of description only.

[0089] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0090] Some embodiments of the present application are described in detail. The following embodiments and features of the embodiments can be combined with each other in the case of no conflict.

[0091] Referring to Figure 1 The present embodiment provides a vehicle 300, comprising a vehicle body 301, a side wall assembly 200 and a rearview mirror 302. The side wall assembly 200 is arranged on the vehicle body 301, and the rearview mirror 302 is connected to the vehicle body 301.

[0092] Referring to Figure 1 and Figure 2 The side wall assembly 200 comprises a side wall sheet metal part 201 and a sealing assembly 100. The side wall sheet metal part 201 is provided with a door opening K2. The door opening K2 penetrates the side wall sheet metal part 201 along the thickness direction of the side wall sheet metal part 201. The sealing assembly 100 is connected to the side wall sheet metal part 201 near the edge of the door opening K2.

[0093] In some embodiments, the number of door openings K2 is two. The two 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 sealing assemblies 100 is two. One sealing assembly 100 is arranged in the front door opening K21 and connected to the side wall sheet metal part 201. The other sealing assembly 100 is arranged in the rear door opening K22 and connected to the side wall sheet metal part 201.

[0094] In some embodiments, referring to Figure 3 The sealing assembly 100 comprises the sealing strip 10 and a plurality of partition portions 20. The sealing strip 10 defines a sealing cavity Q1. The plurality of partition portions 20 are arranged in the interior of the sealing strip 10 along the length direction of the sealing strip 10 and separate the sealing cavity Q1 into a plurality of sealing sub-cavities Q2.

[0095] Thus, each sealing sub-cavity Q2 can provide a certain deformation amount, and the plurality of mutually spaced sealing sub-cavities Q2 have higher strength and better impact resistance than a single sealing cavity, and can achieve the effect of reinforcing the area of the sealing strip 10. After long-term use of the sealing assembly 100, the wall of the sealing strip 10 can have attenuation problems such as softening. However, the partition portions 20 of the present embodiment can stably support the sealing strip 10. Even if the wall of the sealing strip 10 is soft, the sealing assembly 100 can still maintain good support 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, the plurality of mutually independent sealing sub-cavities Q2 can also alleviate the inconsistent attenuation phenomenon caused by different compression amounts of the sealing strip 10, thereby further alleviating the sealing failure problem caused by inconsistent attenuation, thereby further improving the service life of the sealing assembly 100 and ensuring long-term use stability.

[0096] In some embodiments, the sealing strip 10 is in a closed annular shape, and the plurality of partition portions 20 are arranged in sequence 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 wall panel 201 corresponding to the door opening K2 of the vehicle.

[0097] In some embodiments, along the height direction of the vehicle 300, the portion of the sealing strip 10 above the window sill line (not shown in the figure) of the vehicle 300 is provided with a plurality of partition portions 20. The side door of some known vehicles is curved towards the interior space of the vehicle from bottom to top. During the upward movement of the glass, the glass is curved towards the interior space of the vehicle, thereby making the contact with the sealing strip more closely, so that the known glass exerts a greater force on the portion of the sealing assembly above the window sill line of the vehicle during the upward movement of the glass. Similarly, in the closed state of the glass, the glass also exerts a greater force on the sealing strip during the closing of the door. Therefore, during the opening and closing of the door and the lifting and lowering of the glass 202, the portion of the sealing assembly 100 above the window sill line is the main stress area. Therefore, in the area where the sealing strip 10 needs to improve the sealing reliability and service life of the vehicle 300, the partition portions 20 are added, which can simultaneously consider the production cost of the sealing assembly 100 and ensure the sealing reliability.

[0098] In some embodiments, the distance between two adjacent partitions 20 along the extending direction of the sealing strip 10 is between 150mm and 200mm. For example, the distance can be any one of 150mm, 160mm, 170mm, 180mm, 190mm, and 200mm. The distance can be adjusted according to the installation environment of the sealing assembly 100, which is not limited in the present embodiment. In addition, the distance between two adjacent partitions 20 refers to the straight-line distance between the two adjacent partitions 20 when the sealing strip 10 is in a flat state.

[0099] In some embodiments, the vehicle 300 further comprises a door (not shown in the figure) and the glass 202, and the door is a frameless door. The glass 202 is arranged in the frameless door in a liftable manner. The sealing performance of the sealing structure between the door and the side panel 201 is required to be higher during the opening and closing process of the frameless door. Since the sealing assembly 100 of the present embodiment has slower attenuation and higher sealing reliability compared with the existing sealing element, the sealing failure probability of the vehicle 300 using the frameless door can be reduced, and the use reliability of the vehicle 300 can be improved. In addition, since the sealing reliability between the glass 202 and the sealing assembly 100 is higher, the amount of noise conducted 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.

[0100] In some embodiments, referring to Figure 4 , the sealing assembly 100 further comprises a connecting portion 40 for connecting the vehicle body 301. The sealing strip 10 comprises 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 two 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 edges of the partitions 20 are connected to the inner surfaces of the supporting portion 12, the first sealing portion 11, and the connecting portion 40.

[0101] In some embodiments, referring to Figure 4 , the connecting portion 40 comprises 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 the supporting portion 12. The first connecting wall 41 is spaced apart 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 enclose 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.

[0102] In some embodiments, referring to Figure 4The connecting portion 40 further comprises a first abutting strip 45 and a second abutting strip 46. The first abutting strip 45 is arranged on the surface of the third connecting wall 43 facing the first fixed groove C1, and the second abutting strip 46 is arranged on the surface of the first connecting wall 41 facing the first fixed groove C1. The side wall sheet metal part 201 corresponding to the edge of the door opening K2 is clamped between the first abutting strip 45 and the second abutting strip 46, so as to improve the connection reliability between the connecting portion 40 and the side wall sheet metal part 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 wall sheet metal part 201 and the inner wall of the first fixed groove C1, so as to reduce the vibration transmitted by the side wall sheet metal part 201 to the sealing strip 10.

[0103] The number of the first abutting strip 45 and the number of the second abutting strip 46 can be multiple.

[0104] In some embodiments, referring to Figure 4 The connecting portion 40 further comprises a U-shaped steel 47, which is embedded in the interiors of the first connecting wall 41, the second connecting wall 42 and the third connecting wall 43, so as to improve the structural strength of the connecting portion 40 and ensure the reliable connection between the sealing strip 10 and the side wall sheet metal part 201.

[0105] In some embodiments, the connecting portion 40 further comprises a connecting protrusion 44. The connecting protrusion 44 is connected between the first sealing portion 11 and the first connecting wall 41.

[0106] In some embodiments, referring to Figure 4 The sealing assembly 100 further comprises an abutting portion 60. The abutting portion 60 is connected to the second connecting wall 42 and has a cantilever shape. The abutting portion 60 and the second connecting wall 42 form a second fixed groove C2 therebetween. The interior trim panel 203 extends into the second fixed groove C2 and is connected to the abutting 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. Moreover, through the sealing cooperation between the abutting portion 60 and the interior trim panel 203, the external rainwater, dust and the like can be prevented from entering the vehicle body 301 through the gap between the abutting portion 60 and the interior trim panel 203, thereby relieving the rusting of the internal structure of the vehicle body 301 and improving the overall sealing performance of the vehicle 300.

[0107] In some embodiments, referring to Figure 4 The sealing assembly 100 further comprises an abutting protrusion 61. The abutting protrusion 61 is protruded from the inner surface of the abutting portion 60 facing the second fixed groove C2 and abuts to the interior trim panel 203, so as to improve the fixing stability and sealing reliability of the interior trim panel 203.

[0108] In some embodiments, the cross section of the sealing strip 10 is substantially semi-enclosed, the cross section of the partition 20 is substantially semi-enclosed, one end of the semi-enclosed sealing strip 10 is connected to the connecting portion 40, and the other end is abutted to the glass 202. In this way, the sealing strip 10 is deformed to improve the sealing effect.

[0109] In some embodiments, referring to 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 attached to the inner side surface of the glass 202. Here, the inner side and the outer side of the glass 202 are relative to the inner and outer spaces in the left-right direction of the vehicle 300. For example, the inner side surface of the glass 202 located on the left side door of the vehicle 300 refers to the right side surface of the glass 202, and the inner side surface of the glass 202 located on the right side door of the vehicle 300 refers to the left side surface of the glass 202.

[0110] When the glass 202 is raised and the door is closed, the first sealing portion 11 is attached to the inner side surface of the glass 202, so that the gap between the glass 202 and the door frame can be better filled by the first sealing strip 10. Thus, by cooperating with the glass 202 through the first sealing portion 11, the sealing performance of the glass 202 when the door is closed can be better guaranteed, so that external rainwater, dust, etc. can be prevented from entering the inside 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, the noise such as wind noise from the external environment in the passenger space can be reduced, which is beneficial to improve the comfort of the driver and the passenger.

[0111] In some embodiments, referring to Figure 4 The side surface of the first sealing portion 11 away from the connecting portion 40 is a smooth curved surface, i.e. the side surface of the side of the first sealing portion 11 facing the glass 202 is a smooth curved surface. Thus, 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 in a direction away from the center of the glass 202 in a direction towards the outside of the vehicle 300, so as to increase the projected 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.

[0112] In some embodiments, referring to Figure 4The one end of the support part 12 is connected with the one end of the first sealing part 11 close to the glass 202, and the other end of the support part 12 is connected with the first connecting wall 41 of the connecting part 40, so that the first sealing part 11, the support part 12 and the connecting part 40 can form a substantially triangular structure, which is beneficial to improve the stability of the sealing strip 10. When the first sealing part 11 is pressed by the glass 202, the first sealing part 11 pushes the support part 12 to deform, and the shape of the sealing cavity Q1 changes accordingly. When the pressing force acting on the first sealing part 11 disappears, the support part 12 and the first sealing part 11 recover from the deformation, and the sealing cavity Q1 returns to the initial state.

[0113] In some embodiments, the side of the support part 12 away from the sealing cavity Q1 is recessed towards the sealing cavity Q1. When the first sealing part 11 is pressed by the glass 202, the first sealing part 11 pushes the support part 12 to bend and deform towards the sealing cavity Q1, which can better avoid the interference of the support part 12 bending away from the sealing cavity Q1.

[0114] In some embodiments, referring to Figure 4 The vehicle 300 further includes a B-pillar housing 204. The sealing assembly 100 further includes a second sealing part 50. The B-pillar housing 204 is arranged outside the side wall panel 201 to shield the side wall panel 201, thereby improving the overall appearance of the vehicle 300. The B-pillar housing 204 has an assembly part 51, and a buffer 70 is arranged between the assembly part 51 and the outer side of the side wall panel 201. The buffer 70 can buffer the impact force between the assembly part 51 and the side wall panel 201 to reduce the transmission of vibration and friction noise. The assembly part 51 and the B-pillar housing 204 define a mounting groove C3, and the opening of the mounting groove C3 faces the glass 202. The second sealing part 50 is arranged in the mounting groove C3. In this way, the installation of the second sealing part 50 can be better ensured, and the installation of the second sealing part 50 can make full use of the space in the B-pillar housing 204, and the layout is compact. In addition, the second sealing part 50 is arranged on the side of the B-pillar housing 204 facing the glass 202, which is beneficial to reduce the matching difficulty of the second sealing part 50 and the glass 202.

[0115] In some embodiments, referring to Figure 4The second sealing part 50 includes an assembly part 51, a first sealing lip 52 and a second sealing lip 53. The assembly part 51 is arranged in the mounting groove C3, and the first sealing lip 52 and the second sealing lip 53 are arranged on the side of the assembly part 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 from the fixed end of the first sealing lip 52 towards the free end, the first sealing lip 52 and the second sealing lip 53 extend in a C shape towards each other, 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 part 51. The outer side of the first sealing lip 52 is adapted to fit with the side of the glass 202 facing the B-pillar housing 204, and the outer side of the second sealing lip 53 is adapted to fit with the inner side 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 better filled by the second sealing part 50, and at the same time the sealing strip 10 also forms a sealing fit with the glass 202, so that the sealing assembly 100 can form a three-layer sealing of the glass 202, which is beneficial to further improve the sealing effect of the frameless vehicle door. The sealing strip 10 and the second sealing part 50 are spaced apart to avoid interference when the sealing strip 10 and the second sealing part 50 deform.

[0116] In some embodiments, referring to Figure 4 The side of the connecting part 40 facing the sealing cavity Q1 is provided with a plurality of spaced first matching protrusions 13, and the side of the first sealing part 11 facing the sealing cavity Q1 is provided with a plurality of spaced second matching protrusions 14. One of the two adjacent sides of the partition part 20 matches the plurality of first matching protrusions 13, and the other of the two adjacent sides of the partition part 20 matches the plurality of second matching 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 of the partition part 20 and the sealing strip 10.

[0117] In some embodiments, referring to Figure 5 and Figure 6 At least part of the partition part 20 is a partition partition part 31, and the two sealing sub-cavities Q2 located on both sides of the partition partition part 31 are not connected to each other.

[0118] In the part of the sealing assembly 100 corresponding to the plurality of spaced partition partition parts 31, since the plurality of sealing sub-cavities Q2 are not connected to each other, the sealing reliability can be further enhanced when the sealing assembly 100 is subjected to pressure, and the decay phenomenon of the region of the sealing strip 10 corresponding to the sealing sub-cavities Q2 not connected to each other can be delayed, while the buffering effect can be ensured and the wear phenomenon can be slowed down, thereby prolonging the service life of the sealing assembly 100.

[0120] In the part of the sealing assembly 100 corresponding to the multiple spaced-apart partition partitions 31, when the sealing assembly 100 is subjected to pressure in this part, the air flow between the two adjacent sealing sub-cavities Q2 can flow to each other, thereby increasing the deformation size of each sealing sub-cavity Q2 when subjected to force, and under the premise of ensuring a certain sealing reliability, it can further provide a certain buffering effect. And after this part is in a stressed state, because each sealing sub-cavity Q2 is communicated with each other, the air pressure of the corresponding part of the sealing assembly 100 is balanced, which can ensure the sealing performance of this part, thereby improving the sealing reliability, buffering reliability and impact resistance of the sealing assembly 100.

[0121] In some embodiments, please participate again Figure 2 The side wall panel 201 is provided with a top area A1, four corner areas A2 and a window sill line area A3 corresponding to the edge of the door opening K2. The top area A1 is located on the upper side of the side wall panel 201, the four corner areas A2 are located at the four corners of the door opening K2, and the window sill line area A3 is located on the side of the door opening K2 close to the B-pillar shell 204 and corresponds to the area at the position of the window sill line. The area of the side wall panel 201 corresponding to the rearview mirror 302 is the rearview mirror area A4, and the rearview mirror area A4 is specifically the area on the vehicle body 301 corresponding to the A-pillar (not shown in the figure) mounting the rearview mirror 302.

[0122] For reference Figure 7 and Figure 8The sealing strip 10 of the sealing assembly 100 comprises 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 form a closed annular structure, so that the sealing strip 10 is stably installed in the door opening K2. The top section 15 is provided with a first reinforcing 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 reinforcing area B2, and the part of the first side section 17 corresponding to the window sill line is provided with a third reinforcing area B3. The connection between the top section 15 and the second side section 18 is provided with a fourth reinforcing area B4. At the sealing assembly 100 installed in the rear door opening K22, the connection between the top section 15 and the first side section 17 is provided with a second reinforcing area B2, the connection between the top section 15 and the second side section 18 is provided with a second reinforcing area B2, and the part of the first side section 17 corresponding to the window sill line is provided with a third reinforcing area B3. The first reinforcing area B1 corresponds to the top area A1, the second reinforcing area B2 corresponds to the corner area A2, the third reinforcing area B3 corresponds to the window sill line area A3, and the fourth reinforcing area B4 corresponds to the rearview mirror area A4.

[0123] In some embodiments, referring to Figure 7 and Figure 8 The sealing strip 10 of the sealing assembly 100 is provided with a communication partition 32 and at least two blocking partitions 31 corresponding to the top area A1, the two blocking partitions 31 are located at both ends of the top area A1, and the communication partition 32 is located between the two blocking partitions 31.

[0124] During the lifting of the glass 202 of the door, a certain impact force is generated on the top area A1 of the side wall panel 201. By providing the communication partition 32 and the at least two blocking partitions 31 corresponding to the top area A1 of the sealing strip 10, when the sealing strip 10 is impacted, the multiple sealing sub-cavities Q2 formed by the communication partition 32 and the blocking partitions 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 communication hole K1 of the communication partition 32, so that the buffering performance of the part of the sealing strip 10 corresponding to the top area A1 is stronger, thereby improving the passing performance of the glass 202. In this way, the glass 202 can realize the opening and closing effect of fast lifting and fast lowering, and ensure the application reliability of the frameless door. In addition, after the glass 202 is completely closed, the air flow of the multiple sealing sub-cavities Q2 corresponding to the top area A1 of the sealing strip 10 can realize air pressure balance through the communication hole K1, so that the sealing reaction force of the sealing strip 10 corresponding to the top area A1 is relatively uniform, thereby ensuring the sealing performance of the glass 202 at the top area A1.

[0125] Specifically, in the present embodiment, two partitioning portions 31 and a plurality of connecting portions 32 are provided at the first reinforcing region B1. The number of connecting portions 32 can be adjusted according to the length of the top section 15. For example, the number of connecting portions 32 of the first reinforcing region B1 is three at the top section 15 of the sealing assembly 100 installed at the front door opening K21, and the number of connecting portions 32 of the first reinforcing region B1 is two at the top section 15 of the sealing assembly 100 installed at the rear door opening K22.

[0126] In some embodiments, referring to Figure 7 and Figure 8 , the sealing strip 10 of the sealing assembly 100 is provided with a connecting portion 32 and at least two partitioning portions 31 corresponding to the corner region A2, and the two partitioning portions 31 are located at both ends of the corner region A2, and the connecting portion 32 is located between the two partitioning portions 31.

[0127] During the opening and closing of the door, the door will generate a certain impact force on the corner region A2. By providing the connecting portion 32 and the at least two partitioning portions 31 corresponding to the top region A1 of the sealing strip 10, when the sealing strip 10 is impacted, the plurality of sealing sub-cavities Q2 formed by the connecting portion 32 and the partitioning portions 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 communication hole K1 of the connecting portion 32, thereby making the buffering performance of the part of the sealing strip 10 corresponding to the corner region A2 stronger, so as to improve the closing buffering performance of the door. In this way, the reliability of the opening and closing process of the frameless door is ensured. In addition, after the door is completely closed, the plurality of sealing sub-cavities Q2 of the part of the sealing strip 10 corresponding to the corner region A2 can realize air pressure balance through the airflow of the communication hole K1, so that the sealing reaction force of the sealing strip 10 corresponding to the corner region A2 is relatively uniform, so as to ensure the sealing performance of the door at the corner region A2.

[0128] Among them, on the upper side of the door opening K2 along the height direction of the vehicle 300, the corner region A2 is the corner region A2 of the side wall panel 201 corresponding to the door opening K2 on both sides of the length direction of the vehicle 300.

[0132] In this way, the sealing strip 10 is locally reinforced at the windowsill line area A3 to alleviate the attenuation problem of the sealing strip 10 at the part corresponding to the windowsill line area A3 (i.e., the third reinforcing area B3), thereby prolonging the reliability of the sealing strip 10, reducing the sealing failure problem at the windowsill line area A3, and further reducing the water leakage, wind noise, and other problems caused by sealing failure, thereby improving the user experience. Moreover, since the attenuation of the sealing strip 10 at the part of the windowsill line area A3 is alleviated, the vehicle door can be designed as a frameless vehicle door, thereby balancing the appearance and performance of the vehicle 300.

[0133] Specifically, in the present embodiment, the number of partitioning portions 31 provided at the third reinforcing area B3 can be two, three, four, or more.
