Technical Field

[0001] This utility model relates to the field of automobile body, and in particular to a frameless door sealing structure and vehicle. Background Technology

[0002] Frameless vehicles refer to car models where the doors lack an upper outer frame. In these models, the upper part of the windows is suspended, and the windows are sealed to the doors using the roof and side panels. Therefore, the sealing structure of frameless vehicles requires extremely high standards in terms of manufacturing processes and materials. In related technologies, the roof sealing strip contacts and is compressed against the side panel assembly. However, after repeated opening and closing of the doors and raising and lowering of the windows, the roof sealing strip may shift and separate from the side panel assembly, creating gaps that can lead to leaks of water and dust.

[0003] Therefore, there is an urgent need for a frameless door sealing structure to solve the above-mentioned technical problems. Utility Model Content

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] In response to the issue that in related technologies, the roof sealing strip may shift and separate from the side assembly under repeated pressure from frameless door glass, resulting in gaps between the roof sealing strip and the side assembly, which can easily lead to problems such as water and dust leakage, this utility model provides a frameless door sealing structure that can keep the roof sealing strip and the side assembly in a fixed position to eliminate gaps.

[0031] like Figures 1 to 3 As shown, this utility model provides a frameless car door sealing structure, which includes a car body and a top sealing strip 4. The car body includes a side panel assembly, which includes a top side panel sheet metal 1 and a side limiting member 2. A snap-fit ​​groove 3 is formed between the top side panel sheet metal 1 and the side limiting member 2. The side limiting member 2 includes a side panel front triangular cover plate or a corner window exterior trim piece. The top sealing strip 4 is snapped into the top side panel sheet metal 1, and one end of the top sealing strip 4 facing the snap-fit ​​groove 3 is snapped into the snap-fit ​​groove 3.

[0032] Since the top sealing strip 4 is snapped into the top side panel 1, the top sealing strip 4 will not separate from the side panel assembly under the pressure of the window glass. In this way, the top sealing strip 4 and the side panel assembly always maintain a seal, and there will be no problems such as water leakage or leakage, thus improving the sealing effect.

[0033] Taking the side limiting component, including the corner window trim, as an example, the corner window trim and the top side panel sheet metal 1 together form a snap-fit ​​groove 3, and one end of the top sealing strip 4 extends into the snap-fit ​​groove 3 and is snapped and fixed. This can prevent the top sealing strip 4 from moving and separating from the side panel assembly after the car door is opened and closed multiple times and the car window glass is raised and lowered multiple times, so as to improve the overall sealing effect of the frameless car door.

[0034] In some embodiments, such as Figure 3As shown, the side limiting member 2 is bent at one end toward the top sealing strip 4 to form a limiting part 21. The top sealing strip 4 is provided with a sheet metal limiting groove 45, and the limiting part 21 is installed in the sheet metal limiting groove 45. The limiting part 21 extends into the sheet metal limiting groove 45 to limit the top sealing strip 4, thus preventing the top sealing strip 4 from moving along its length and detaching from the side assembly. This also prevents the top sealing strip 4 from shifting under repeated pressure from the door glass, ensuring that the top sealing strip 4 and the side sheet metal assembly always maintain a relatively fixed position. It should be noted that the top sealing strip 4 has a sheet metal limiting groove 45 on the side facing the side limiting member 2 to fix the position of the top sealing strip 4.

[0035] In other embodiments, both sides of the top side sheet metal 1 and the side limiting member 2 of the top sealing strip 4 are provided with sheet metal limiting grooves 45, and the part of the top side sheet metal 1 facing the top sealing strip 4 is provided with a limiting part 21 that can extend into the sheet metal limiting groove 45 to achieve the purpose of double limiting of the top sealing strip 4, so as to improve the fixing effect of the top sealing strip 4.

[0036] In some embodiments, such as Figure 2 As shown, the side assembly also includes an A-pillar and a B-pillar. Along the direction from the B-pillar to the A-pillar, the two opposite sides of the top sealing strip 4 facing the snap-fit ​​groove 3 tend to move closer together. For example, the cross-section of the portion of the top sealing strip 4 that inserts into the snap-fit ​​groove 3 has a triangular structure. This improves the efficiency of the top sealing strip 4 inserting into the snap-fit ​​groove 3, ensuring that the top sealing strip 4 is squeezed and passes through the snap-fit ​​groove 3.

[0037] In some embodiments, a deformable cavity 41 is provided inside the top sealing strip 4. The deformable cavity 41 can deform when the vehicle glass is facing upward, thereby surrounding the top of the vehicle glass and eliminating the gap between the vehicle glass and the side assembly, thus improving the sealing effect of the frameless door.

[0038] Furthermore, the deformation cavity 41 is provided with reinforcing ribs. The reinforcing ribs can improve the strength of the top sealing strip 4 and prevent the top sealing strip 4 from deforming too much after being squeezed, which would result in an unsightly seal when the car body and the door are closed.

[0039] In some embodiments, in order to fix the top sealing strip 4 to the top side panel 1, the top side panel 1 has a top guide rail 11, and the top sealing strip 4 is installed in the top guide rail 11. Specifically, the top sealing strip 4 is snapped into the top guide rail 11. In addition, in order to make the connection between the top sealing strip 4 and the top side panel 1 more secure, the top sealing strip 4 and the top side panel 1 are fixed by adhesive.

[0040] In some embodiments, combined with Figures 2 to 4As shown, the top sealing strip 4 has a snap-fit ​​lip 42 on the side facing the top guide rail 11, and the top guide rail 11 has a limiting protrusion 111. The end of the snap-fit ​​lip 42 abuts against the limiting protrusion 111. Multiple snap-fit ​​lips 42 abut against the limiting protrusion 111 to securely connect the top sealing strip 4 and the top guide rail 11. Alternatively, in some other embodiments, two snap-fit ​​lips 42 may be used, arranged along the length of the vehicle on both sides of the top guide rail 11, also achieving the purpose of securingly connecting the top sealing strip 4 and the top guide rail 11.

[0041] In some embodiments, the top sealing strip 4 is provided with a limiting boss 43, and the top guide rail 11 is provided with a sealing limiting groove 112, with the limiting boss 43 located within the sealing limiting groove 112.

[0042] In some embodiments, in order to facilitate the manufacturing of the top sealing strip 4 and make it easier to form the deformable cavity 41 in the top sealing strip 4, the top guide rail 11 is provided with a clamping groove 113, and the top sealing strip 4 is provided with a flange 44 located in the clamping groove 113. The flange 44 has an arc-shaped structure and bends towards the top side sheet metal 1. The flange 44 extends into the clamping groove 113 so that the flange 44 is clamped and pressed by the clamping groove, thereby fixing the top sealing strip 4 a second time and achieving the purpose of fixing the top sealing strip 4.

[0043] This embodiment also provides a vehicle, which includes a door and a frameless door sealing structure provided in this embodiment of the present invention. The door is connected to the vehicle body and can move relative to the vehicle body. The door can abut against the top sealing strip 4.

[0044] Because the vehicle includes a frameless door sealing structure, and because the top sealing strip 4 is snapped into the top side panel 1, the top sealing strip 4 will not separate from the side panel assembly under the pressure of the window glass. In this way, the top sealing strip 4 and the side panel assembly always maintain a seal, and there will be no problems such as water leakage or leakage, thus improving the sealing effect.

[0045] Because it includes the frameless door sealing structure described above, the vehicle of this utility model embodiment has all the advantages and beneficial effects of the above embodiments, which will not be repeated here.

[0046] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
