[0037] like Figures 1 to 4 As shown, this embodiment provides a door sealing structure, which includes a door 10, a sealing unit 20, and a glass unit 30. The sealing unit 20 is connected to the door 10 and includes a first lip 2311, a second lip 2321, and an abutment protrusion 2313. The glass unit 30 is provided with a first boss 31, a second boss 32, and a recess 33. The recess 33 is located between the first boss 31 and the second boss 32. At least a portion of the abutment protrusion 2313 can be located in the recess 33, so that the first boss 31 and the second boss 32 are located on both sides of the abutment protrusion 2313, and the outer surface of the glass unit 30 is flush with the outer surface of the sealing unit 20. The second lip 2321 abuts against the glass unit 30. Specifically, in this embodiment, the sealing unit 20 is connected to the door 10, which can ensure the installation stability of the sealing unit 20; the part of the structure of the abutment protrusion 2313 can be located in the recess 33, so that the first protrusion 31 and the second protrusion 32 are respectively located on both sides of the abutment protrusion 2313. This arrangement can, on the one hand, ensure that the first protrusion 31 and the second protrusion 32 abut against the abutment protrusion 2313, thereby improving the sealing performance between the glass unit 30 and the sealing unit 20. On the other hand, it can ensure that the outer surface of the glass unit 30 and the outer surface of the sealing unit 20 are flush, thereby ensuring that there is no step difference between the glass unit 30 and the sealing unit 20, improving the appearance performance of the vehicle; and the second lip 2321 can abut against the inner surface of the glass unit 30, further improving the sealing effect.

[0038] Preferably, the surface of the second lip 2321 that abuts against the glass unit 30 is coated with a coating that can reduce wear with the glass substrate.

[0039] Specifically, such as Figure 4 As shown, the glass unit 30 in this embodiment is made of several pieces of glass that are bonded together.

[0040] Furthermore, such as Figure 2As shown, the sealing unit 20 includes a support member 21, a reinforcing member 22, and a sealing member 23 connected together. The reinforcing member 22 is wrapped around the outside of the support member 21, and the sealing member 23 is connected to the reinforcing member 22. Specifically, in this embodiment, the support member 21 is a metal structural component, which can ensure that the sealing unit 20 has good structural strength; the reinforcing member 22 is a rubber component, which is wrapped around the outside of the support member 21 and is used to connect the sealing member 23 and the support member 21. This ensures the normal use of the sealing member 23 and improves the appearance performance. Both the sealing member 23 and the reinforcing member 22 are rubber components, and the hardness of the reinforcing member 22 is greater than that of the sealing member 23. This arrangement allows the reinforcing member 22 to have better connection and support functions, while ensuring that the sealing member 23 has good elasticity, thereby improving the sealing performance of the sealing member 23.

[0041] In one embodiment, the support member 21 is made of iron or aluminum. In other embodiments, the material of the support member 21 can be specifically set according to actual use, and no limitation is made here.

[0042] In one embodiment, both the seal 23 and the reinforcement 22 are made of EPDM, and the hardness of the seal 23 is in the range of 60HA-65HA, while the hardness of the reinforcement 22 is in the range of 75HA-85HA.

[0043] Furthermore, such as Figure 2 As shown, the reinforcing member 22 includes a first reinforcing part 221 and a second reinforcing part 222 connected to each other. The first reinforcing part 221 is wrapped around the outside of the supporting member 21. The sealing member 23 includes a first sealing part 231 and a second sealing part 232. The first sealing part 231 wraps around a portion of the structure of the first reinforcing part 221. The second sealing part 232 is connected to the second reinforcing part 222. A first lip 2311 is disposed on the first sealing part 231, and a second lip 2321 is disposed on the second sealing part 232. Specifically, in this embodiment, the first sealing part 231 wraps around a portion of the structure of the first reinforcing part 221, so that the exposed surface of the sealing structure is the first sealing part 231, thereby improving the appearance performance. Furthermore, the first sealing part 231 and the second sealing part 232 are separately disposed, reducing the use of materials and improving economy.

[0044] Furthermore, such as Figure 2As shown, the first sealing part 231 includes an attachment part 2312 and an abutment protrusion 2313 connected to each other. The attachment part 2312 is attached to the outer peripheral surface of the first reinforcing part 221. The abutment protrusion 2313 and the first reinforcing part 221 are spaced apart to form an air groove 2314 between the first sealing part 231 and the first reinforcing part 221. The air groove 2314 is located on the side of the abutment protrusion 2313 away from the glass unit 30. Specifically, in this embodiment, the attaching portion 2312 is attached to the first reinforcing portion 221, which enables the first sealing portion 231 to have sufficient support, thereby ensuring the sealing effect of the first sealing portion 231; the abutting protrusion 2313 and the first reinforcing portion 221 are spaced apart, thereby forming an air groove 2314 between the abutting protrusion 2313 and the first reinforcing portion 221. The air groove 2314 enables the abutting protrusion 2313 to have a better rebound effect when it contacts the glass unit 30, thereby improving the sealing effect between it and the glass unit 30.

[0045] Furthermore, such as Figure 2 As shown, the abutment protrusion 2313 is inclined, and the second lip 2321 is inclined, with the inclination directions of the abutment protrusion 2313 and the second lip 2321 being opposite. Specifically, in this embodiment, the inclination directions of the abutment protrusion 2313 and the second lip 2321 are opposite, making the abutment protrusion 2313 and the second lip 2321 form an "eight" shape relative to the glass unit 30. This structure can improve the sealing performance of the abutment protrusion 2313, the second lip 2321, and the glass unit 30, ensuring the sealing effect of the sealing structure on the door.

[0046] Furthermore, such as Figure 2 As shown, the sealing unit 20 is provided with a first connecting part, which is used to connect to the vehicle door 10. Specifically, in this embodiment, the provision of the first connecting part can ensure the connection stability between the sealing unit 20 and the vehicle door 10, thereby ensuring the positional stability of the sealing unit 20, and thus ensuring good sealing performance between the sealing unit 20 and the glass unit 30.

[0047] Furthermore, such as Figure 2 As shown, the first connecting part is an insertion groove 2221 formed in the sealing unit 20, and the door 10 and the insertion groove 2221 are inserted and fitted together. Specifically, in this embodiment, as... Figure 3 As shown, the door 10 is a sheet metal structure, which includes a first sheet metal 11, a second sheet metal 12 and a third sheet metal 13. Parts of the structure of the first sheet metal 11 and the structure of the second sheet metal 12 are parallel and fitted to form a first insertion part. The first insertion part and the insertion groove 2221 are inserted and matched, thereby ensuring that the sealing structure and the door 10 are connected conveniently and improving the installation efficiency.

[0048] Specifically, in this embodiment, as Figure 3 As shown, a portion of the structure of the third sheet metal 13 is parallel to and fits into a portion of the structure of the first sheet metal 11 to form a second insertion part. A snap-fit ​​groove 2222 is provided on the second reinforcing part 222. The second insertion part and the snap-fit ​​groove 2222 are fitted together to further improve the connection stability between the sealing unit 20 and the door 10, thereby improving the performance of the sealing structure on the door.

[0049] Specifically, in this embodiment, as Figure 2 As shown, the second reinforcing part 222 is also provided with an abutting part 2315, which can abut against the door 10, thereby improving the support performance of the door 10 on the sealing unit 20, thereby improving the stability of the sealing unit 20 in use, and ensuring the relative stability between the glass units 30 of the sealing unit 20.

[0050] Furthermore, such as Figure 1 and Figure 2 As shown, the sealing unit 20 also includes a plurality of third lips 24, which are disposed in the insertion groove 2221 and abut against the door 10. Specifically, in this embodiment, four third lips 24 are provided, which are spaced apart along the extension direction of the insertion groove 2221. All four third lips 24 can abut against the insertion part of the door 10, thereby not only improving the sealing performance of the door 10 and the sealing unit 20, but also improving the installation stability of the door 10 and reducing the noise caused by the vibration of the door 10.

[0051] Specifically, in this embodiment, one of the third lips 24 is located at the opening of the insertion slot 2221, which can reduce the vibration of the door 10, thereby improving installation stability and reducing noise.

[0052] Furthermore, such as Figure 1 As shown, the sealing structure on the car door also includes a side panel 40, which is installed at the upper edge of the car door 10, and the first lip 2311 can abut against the side panel 40. Specifically, in this embodiment, the abutment between the first lip 2311 of the sealing structure and the side panel 40 can ensure the sealing performance between the car door 10 and the side panel 40, thereby ensuring the effectiveness of the sealing structure on the car door.

[0053] Preferably, in this embodiment, the end face of the first lip 2311 facing the side wall 40 is flocked, which can improve the sealing performance between the side wall 40 and the sealing structure, and also effectively reduce noise.

[0054] like Figure 1As shown, this embodiment also provides a vehicle, which includes a window frame trim panel 50 and the aforementioned door sealing structure. The sealing unit 20 is provided with a slot 2223, and the window frame trim panel 50 is snapped into the slot 2223. Specifically, in this embodiment, the second reinforcing part 222 is also provided with a slot 2223. The slot 2223 is located on the side of the second reinforcing part 222 opposite to the slot 2222. When the window frame trim panel 50 is snapped into the slot 2223, the window frame trim panel 50 and the first lip 2311 are flush, which can improve the aesthetics of the vehicle and enhance its competitiveness.
