[0036] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the sealing member provided by the embodiment of the present disclosure includes a body, and the body includes a first connecting section 31, a second connecting section 32, a third connecting section 33 and a mounting section 34; the first connecting section 31, the second connecting section 32 and the third connecting section 33 all extend along the length direction of the body, and the first connecting section 31, the second connecting section 32, the third connecting section 33 and the mounting section 34 are sequentially connected to form a cavity structure 30, which can be used to withstand the closing force of the vehicle door; the mounting section 34 is used to connect with the vehicle door, and the third connecting section 33 is used to abut against the side wall 5; the second connecting section 32 is provided with a first lip edge 321 extending in a direction away from the vehicle door, the first lip edge 321 extends along the length direction of the body, and the second connecting section 32 and the first lip edge 321 form a shielding surface on the surface facing the wheel. The sealing member is connected to the vehicle door sheet metal, and after the door is closed, the sealing member contacts the side wall 5 to play a sealing role, and the sealing member shields the gap between the vehicle door sheet metal and the side wall 5, thereby playing a sealing function such as mud blocking. The first lip edge 321 can shield the side panel 5, reducing the possibility of water or mud splashing onto the side panel 5. The first lip edge 321 can extend the shielding surface, increase the shielding area, and reduce the possibility of water or mud adhering to the outer panel of the side panel 5. The seal can reduce the possibility of dirt adhering to the outer panel of the side panel 5 while meeting the sealing performance requirements, and reduce the possibility of passengers' clothes getting dirty when getting on and off the vehicle, thereby significantly improving the user experience of the vehicle and improving the appearance quality and quality of the entire vehicle.

[0037] Therefore, the seal provided in the embodiment of the present disclosure can fill the gap between the vehicle door and the side panel 5 after assembly, has effective sealing performance, and improves the appearance quality and quality of the entire vehicle.

[0038] The seal can be made of EPDM material. The first connecting section 31, the second connecting section 32, the third connecting section 33 and the installation section 34 are connected in sequence to form a cavity structure 30. The cavity structure 30 cooperates with the side panel 5. The seal contacts the side panel 5 through the cavity structure 30 to play a sealing role. The seal blocks the gap between the door sheet metal and the side panel 5, thereby playing a sealing function such as mud blocking. The side panel 5 can be blocked by the first lip edge to reduce the possibility of water or mud splashing onto the side panel 5. The shielding surface can be extended by the first lip edge to increase the shielding area, and reduce the possibility of water or mud adhering to the outer panel of the side panel 5. The seal can reduce the possibility of dirt adhering to the outer panel of the side panel 5 while meeting the sealing performance, and reduce the possibility of passengers getting their clothes dirty when getting on and off the vehicle, which significantly improves the use experience of the vehicle and improves the appearance quality and quality of the entire vehicle.

[0039] The seal provided in the embodiment of the present disclosure is also applicable to full-enclosed door and half-enclosed door structures.

[0040] The vehicle door comprises a vehicle door inner panel 3 and a vehicle door outer panel 4 . In this embodiment, the sealing member is connected to the vehicle door inner panel 3 .

[0041] In some specific embodiments, the outer wall of the third connection section 33 is protruded away from the cavity structure 30, and the protrusion extends along the length direction of the body. When the door is closed and the side enclosure 5 squeezes the seal, the protrusion is easy to deform, which can share the squeezing force of the side enclosure 5, reduce the friction between the seal and the side enclosure 5, and solve the problems of seal wear and paint abrasion. The protrusion can make the seal and the side enclosure 5 form elastic contact, improve the sealing performance, and make the third connection end have good restoring force, so that it can recover quickly when the door is opened.

[0042] Optionally, the outer wall of the third connecting section 33 forms a raised portion that rises away from the cavity structure 30, and the raised portion extends along the length direction of the body. The raised portion makes the third connecting section 33 easy to collapse. When the door is closed and the side panel 5 squeezes the seal, the raised portion is easy to deform, which can share the squeezing force of the side panel 5, reduce the friction between the seal and the side panel 5, and solve the problems of seal wear and paint abrasion. The raised portion can make the seal and the side panel 5 form elastic contact, improve the sealing performance. The raised portion makes the third connecting end have good restoring force, and can quickly recover when the door is opened.

[0043] In some specific embodiments, the outer wall of the first connecting section 31 is recessed toward the cavity structure 30, or the outer wall of the first connecting section 31 forms a recessed portion recessed toward the cavity structure 30, and the recess or recessed portion extends along the length direction of the body, and the recess or recessed portion is used to form a cavity 6 with the door. When the door is closed and the side enclosure 5 squeezes the seal, an impact force is generated on the seal to squeeze the cavity structure 30, thereby impacting the first connecting section 31. On the one hand, the recess or recessed portion makes the first connecting section 31 easy to collapse, which can share the squeezing force of the side enclosure 5. On the other hand, through the active collapse of the raised first connecting section 31 and the third connecting section, the possibility of deformation of the second connecting section 32 can be reduced, so that the shielding surface formed by the second connecting section 32 can effectively shield water or mud and sand. Through the active collapse of the raised first connecting section 31 and the third connecting section, the possibility of deformation of the second connecting section 32 can be reduced, and the appearance quality and quality of the vehicle can be improved.

[0044] In some specific embodiments, the connection portion between the first connection section 31 and the second connection section 32 is provided with a second lip 322 extending toward the vehicle door and extending along the length direction of the body, and the second lip 322 is used to abut against the vehicle door. The second lip 322 can increase the squeezing force between the seal and the vehicle door and improve the stability of the seal.

[0045] In some specific embodiments, the first connecting section 31 is provided with an exhaust hole 311. When the side enclosure 5 squeezes the seal, it will generate an impact force on the seal to squeeze the cavity structure 30, and the gas in the cavity structure 30 can be discharged from the exhaust hole 311 to release the pressure. The pressure released from the cavity structure 30 enters the cavity 6, and then can be discharged from the abutment between the second lip 322 and the door. When the gas is discharged from the abutment between the second lip 322 and the door, the mud and sand attached to the door can be blown out, which can improve the appearance quality and quality of the vehicle.

[0046] In some specific embodiments, the installation section 34 is connected to an extension section 35, which extends along the length direction of the body; the extension section 35 forms a mounting cavity 351, which extends along the length direction of the body, and the extension section 35 is provided with a mounting hole communicating with the mounting cavity 351. A buckle 7 is provided in the mounting hole, and the seal can be connected to the vehicle door through the buckle 7.

[0047] In some specific embodiments, the surface of the mounting section 34 facing the vehicle door is provided with a first claw portion 341, and the first claw portion 341 protrudes from the mounting section 34; the surface of the extension section 35 facing the vehicle door is provided with a second claw portion 352, and the second claw portion 352 protrudes from the extension section 35; the mounting hole is located between the first claw portion 341 and the second claw portion 352. The first claw portion 341 and the second claw portion 352 can provide a pre-tightening force after the buckle 7 is connected to the vehicle door, thereby improving the stability and sealing performance of the seal.

[0048] In some specific embodiments, the thickness of the second connecting section 32 and the thickness of the first connecting section 31 are both greater than the thickness of the third connecting section 33. When the side panel 5 squeezes the seal, the raised portion is easy to deform, which can share the squeezing force of the side panel 5, reduce the friction between the seal and the side panel 5, and solve the problems of seal wear, paint grinding, etc.

[0049] In some specific embodiments, the hardness of the second connecting segment 32 and the hardness of the first connecting segment 31 are both greater than the hardness of the third connecting segment 33. When the side panel 5 squeezes the seal, the raised portion is easy to deform, which can share the squeezing force of the side panel 5, reduce the friction between the seal and the side panel 5, and solve the problems of seal wear, paint grinding, etc.

[0050] In some specific embodiments, along the length direction of the body, the body includes a middle region 3 and a first corner 1 and a second corner 2 located at both ends of the middle region 3; the hardness of the first corner 1 and the hardness of the second corner 2 are both greater than the hardness of the middle region 3, which can improve the stability of the seal connection. The middle region 3 can be extruded,

[0051] The first corner 1, the second corner 2 and the middle area 3 are fixed to the door sheet metal by means of buckles 7. The first corner 1 and the second corner 2 of the seal can be integrally molded with the straight section of the middle area 3 by using EPDM dense glue; the straight section of the middle area 3 is extruded by double compounding of EPDM sponge glue and EPDM dense glue.

[0052] The gap between the side panel 5 and the door sheet metal is sealed by a seal to prevent the entry of mud and sand; the buckle 7 is made of PA66 material by injection molding.

[0053] The vehicle door provided in the embodiment of the present disclosure includes the sealing member provided in the embodiment of the present disclosure.

[0054] The vehicle provided by the embodiment of the present disclosure includes the vehicle door provided by the embodiment of the present disclosure.
