AI Technical Summary
Due to structural design or installation errors, the transition between the side panel sealing strip and the A-pillar sealing strip may result in a poor seal between the vehicle body and the frameless door, causing gaps and problems such as wind noise and rainwater infiltration, which affect the comfort and safety of the vehicle.
A sealing device is designed, including a side sealing strip, a side sealing corner, and an A-pillar sealing strip. A first lip and a second lip are used to form a snap-fit with the main body of the sealing strip to engage with the top edge of the frameless door. The connection between the third lip and the second lip ensures the continuity of the sealing device in the corner transition area of the vehicle body and reduces the risk of gaps.
It improves the sealing between the frameless door and the body, reduces the risk of wind noise and rainwater infiltration, and enhances the overall sealing and comfort of the vehicle.

A sealing device for sealing a gap between a frameless door and a vehicle body when the frameless door is closed, characterized by, The sealing device includes: The side sealing strip includes a sealing strip body, a first lip, and a second lip. The sealing strip body is used to be installed on the vehicle body. The first lip and the second lip are respectively connected to two inner walls of the sealing strip body that are arranged opposite to each other in a first direction. The sealing strip body, the first lip, and the second lip form a first snap-fit to engage with the top edge of the frameless door when the frameless door is closed. A side sealing corner is connected to one end of the side sealing strip. The side sealing corner includes a sealing corner body and a third lip connected to the sealing corner body. The sealing corner body is connected to the sealing strip body, and the third lip extends in a direction away from the sealing corner body to connect to the second lip.
2. The sealing device of claim 1, wherein The sealing strip body, the first lip, and the second lip are integrally formed.
3. The sealing device of claim 1, wherein The sealing strip body includes a top sealing portion, a first side sealing portion, and a second side sealing portion. The first side sealing portion and the second side sealing portion are spaced apart on the top sealing portion along the first direction. The first lip is provided on the side surface of the first side sealing portion facing the second side sealing portion, and the second lip is provided on the side surface of the second side sealing portion facing the first side sealing portion. The second side sealing portion is configured to be close to the vehicle body.
4. The sealing device of claim 3, wherein The first lip edge and the first side sealing portion form a buffer cavity.
5. The sealing device of claim 3, wherein One end of the second lip is connected to the second side sealing portion, and the other end extends toward the first side sealing portion and is spaced apart from the first lip.
6. The sealed device of claim 3, wherein, The sealing device further includes: A side panel bright strip is used to be installed on the vehicle body, and the side panel bright strip has a second snap-fit, and the main body of the sealing strip is disposed in the second snap-fit and is snap-fitted to the side panel bright strip.
7. The sealing device of claim 6, wherein The second bayonet includes a first sub-bayonet near the top sealing portion and a second sub-bayonet near the first side sealing portion, and the side sealing strip further includes: The fourth lip protrudes and connects to the surface of the top sealing part facing the side bright strip, and the fourth lip is engaged in the first sub-slot; The fifth lip protrudes and connects to the surface of the first side sealing part away from the second side sealing part, and the fifth lip is engaged in the second sub-slot.
8. The sealing device of claim 6, wherein The side sealing strip also includes: A sixth lip is provided on the surface of the top sealing portion away from the side bright strip. One end of the sixth lip is connected to the second side sealing portion, and the other end extends toward the first side sealing portion and is spaced apart from the second lip. The extension direction of the sixth lip is the same as the extension direction of the second lip, and the sixth lip is used to abut against the top edge of the frameless door when the frameless door is closed.
9. The sealed device of claim 1, wherein, The sealing device further includes: The A-pillar sealing strip is fitted to the side A-pillar surface of the vehicle body, and the side sealing corner is transitionally connected between the side sealing strip and the A-pillar sealing strip.
