Description

Technical Field

[0001] This utility model relates to the field of automotive guide groove sealing technology, and in particular to a zero-step automotive sealing structure. Background Technology

[0002] Traditional automotive guide channel sealing strips have a step in their matching with the glass, which is not as good as frameless doors in terms of appearance or wind resistance reduction. However, frameless doors have a complex structure and slightly worse NVH performance. In order to achieve a zero-step sealing design between the door glass and the surrounding trim surface, a zero-step automotive sealing structure is used. To address this issue, patent CN219467501U discloses a car door and automobile with a zero-step differential structure, aiming to solve the problems of slippage and compromised sealing caused by the use of guide grooves in existing zero-step differential car doors. To this end, the car door with a zero-step differential structure provided by this utility model includes an inner door panel, a cover plate, a door glass, a seal, and a clamping member. The seal is located between the cover plate and the door glass. The clamping member includes a rack assembly, a gear, and a connecting rod. One end of the connecting rod is connected to the door glass, and the other end is rotatably connected to the gear. The rack assembly includes a first rack and a second rack. The first rack is located on the inner door panel and meshes with the gear, and the second rack is located on the cover plate and meshes with the gear. The gear is located between the cover plate and the inner door panel. A limiting structure is provided between the gear and the rack to prevent the gear from moving along its own axis. Although the car doors and cars with zero-step structure mentioned above have a seal between the cover and the door glass to isolate the connection between the inside and outside of the door and improve the sealing performance, their use is limited due to insufficient protective measures. This makes it difficult to achieve the appearance effect of zero-step glass, reduce the drag coefficient, and reduce the car's energy consumption. Utility Model Content

[0003] The purpose of this invention is to provide a zero-step automotive sealing structure to address the shortcomings of existing zero-step automotive sealing structures in terms of protective measures.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a zero-step automotive sealing structure, including a glass body and a B-pillar trim panel; A B-pillar trim panel is provided on one side of the glass body, an inner door panel is provided on the top of the B-pillar trim panel, a door reinforcement panel is fixed on one side of the bottom of the inner door panel, and an outer side panel is provided on one side of the inner door panel. A sealing mechanism is provided on one side of the top of the outer side panel, and a buffer structure is provided on one side of the bottom of the outer side panel. A protective structure is provided on one side of the bottom end of the inner door panel. The protective structure includes a pillar guide rail provided on one side of the bottom end of the inner door panel. A glass slider is provided inside the pillar guide rail. A guide groove B-pillar sealing strip is fixed on the outer wall of the inner door panel on one side of the pillar guide rail. A sealing component is provided on the side of the glass body away from the B-pillar trim panel. An outer door panel is provided on one side of the sealing component. A second inner door panel is provided on one side of the outer door panel.

[0005] When using this device, the protective structure facilitates the reduction of wind resistance coefficient, thereby improving the applicability of the zero-step automotive sealing structure; the buffer structure facilitates the buffering of collision forces, thereby improving the convenience of use; and the sealing mechanism facilitates the protection against rain and dust, thereby improving the sealing performance of the zero-step automotive sealing structure.

[0006] Preferably, the outer surface of the glass body and the outer surface of the B-pillar trim panel are on the same horizontal plane. The column guide rails limit the X / Y offset of the glass body, ensuring stable positioning and no significant shaking during the lifting and lowering process, thus laying the foundation for a zero-step appearance and reliable sealing.

[0007] Preferably, the bottom end of the glass slider extends to the outside of the pillar guide rail and is bonded to the top of the glass body with high-performance adhesive. The glass slider matches the pillar guide rail. The bottom end of the guide groove B-pillar sealing strip is fixed with a sealing lip, and the guide groove B-pillar sealing strip contacts the top of the glass body through the sealing lip. By having the outer surface of the B-pillar trim panel and the outer surface of the glass body on the same horizontal plane, not only can the visual defect of the steps in traditional car doors be eliminated, but the side of the entire vehicle can also present a streamlined and flush effect, which improves aesthetics and reduces wind resistance at high speeds. Because the sealing lip of the guide groove B-pillar sealing strip is always in contact with the glass body during the raising and lowering of the glass body, it plays a role in sound insulation and noise reduction.

[0008] Preferably, the buffer structure includes a door anti-pinch strip, a protrusion, and a hook-on lip. The door anti-pinch strip is disposed on one side of the bottom of the outer side panel, the protrusion is fixed inside the door anti-pinch strip, and the hook-on lip is fixed at the bottom end of the door anti-pinch strip. When the door is closed, the door anti-pinch strip, through its elastic deformation, can buffer the impact force and prevent hard contact damage to components.

[0009] Preferably, the bottom end of the protrusion contacts the top end of the outer side panel, and the bottom end of the hook lip contacts the top end of the B-pillar trim panel. The protrusion helps to buffer the impact force when the door closes, preventing a hard collision between the door and the body, reducing component wear, and making the closing action smoother and quieter.

[0010] Preferably, the sealing mechanism includes a door opening sealing strip, a first lip, and a second lip. The door opening sealing strip is disposed on one side of the top of the outer side panel. The first lip is fixed to the bottom of the door opening sealing strip, and the second lip is fixed to one side of the door opening sealing strip. Through contact with the outer side panel, the first lip, through its elastic deformation, initially seals the gap. With the combined action of the door opening sealing strip and the first lip, it can block most of the rainwater, dust, and airflow.

[0011] Preferably, the top of the first lip abuts against the outer side of the side panel, and one side of the second lip abuts against one side of the inner door panel. The second lip, in conjunction with the door opening sealing strip, further enhances the sealing effect, thereby improving the reliability of waterproofing and sound insulation.

[0012] Preferably, the sealing assembly includes a top sealing strip for the guide groove, an aluminum trim piece, and a top gap sealing strip. The top sealing strip for the guide groove is disposed on one side of the glass body, and an aluminum trim piece is disposed on the outer side of one end of the top sealing strip for the guide groove. The top gap sealing strip is disposed on the top of the aluminum trim piece. The top sealing strip for the guide groove is installed on the inner side of the aluminum trim piece by a snap-fit ​​method, thus achieving a zero-step difference effect in appearance.

[0013] Preferably, one side of the aluminum trim abuts against one side of the outer door panel, and one end of the top seam sealing strip extends to the outside of the aluminum trim and abuts against the outside of the outer door panel.

[0014] The advantages of the zero-step automotive sealing structure provided by this utility model are as follows: By incorporating a protective structure and utilizing the column guide rails, the glass body's X / Y offset can be limited, ensuring stable positioning and minimal wobbling during lifting and lowering. This lays the foundation for a zero-step appearance and reliable sealing. The outer surface of the B-pillar trim panel is flush with the outer surface of the glass body, eliminating the visual defect of traditional door steps and creating a streamlined, flush effect on the vehicle's side profile. This enhances aesthetics and reduces wind resistance at high speeds. The B-pillar sealing strip, with its sealing lip always in contact with the glass body during lifting and lowering, provides sound insulation and noise reduction, thus facilitating a reduction in drag coefficient and improving the applicability of this zero-step automotive sealing structure. By incorporating a buffer structure, when the car door is closed, the anti-pinch strip can buffer the impact force through its elastic deformation, preventing hard contact damage to components. The protrusions can also buffer the impact force when the car door closes, preventing hard collisions between the door and the car body. This reduces component wear and makes the closing action smoother and quieter, thus realizing the function of the device in buffering impact forces and improving the convenience of using the zero-step automotive sealing structure. By incorporating a sealing mechanism, the first lip contacts the outer side panel. Under the action of the first lip, its elastic deformation initially seals the gap. With the combined action of the door opening sealing strip and the first lip, it can block most of the rainwater, dust, and airflow. The second lip assists the door opening sealing strip, further blocking the gap and improving the reliability of waterproofing and sound insulation. This device effectively prevents rainwater and dust, thereby enhancing the sealing performance of the zero-step automotive sealing structure during use. Attached Figure Description
