Description

Technical Field

[0001] The present invention relates to the technical field of automotive sealing strips, and more particularly, to a composite sealing strip cross-sectional structure. Furthermore, the present invention relates to a frameless vehicle door including the composite sealing strip cross-sectional structure. Furthermore, the present invention relates to a vehicle including the frameless vehicle door. Background Art

[0002] Frameless doors refer to windows that adopt a frameless design. Its notable feature is that the side glass is flush with the B-pillar and C-pillar, and the glass edge is not wrapped by the door frame. It can fit tightly with the car body to achieve a seamless appearance effect, and help optimize the vehicle's aerodynamic performance, thereby reducing wind resistance. Therefore, frameless doors have been widely used.

[0003] Frameless doors lack a frame, limiting the installation location of sealing strips. Consequently, the window's sealing is almost entirely dependent on the glass and the limited sealing strips. Therefore, the sealing strips must possess excellent elasticity and wear resistance to ensure a perfect seal when the window is closed, effectively preventing wind and rain intrusion.

[0004] However, the cross-sectional structures of the sealing strips of existing frameless car doors are mainly split sealing strips and integral sealing strips, such as Figure 1 As shown in the figure, the split sealing strip has good sealing performance, but because the glass sealing strip and the B-pillar sealing strip are set separately, the sealing strip has many layers, the appearance is messy, and the appearance effect is poor; Figure 2 As shown, although the integral sealing strip is an integral structure with a simple and beautiful appearance, the glass is only sealed in the Y direction and the sealing performance is poor; therefore, the existing sealing strip cross-sectional structure can no longer meet people's needs.

DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0028] like Figure 3 and Figure 4 As shown, the cross-sectional structure of the composite sealing strip of this embodiment includes a glass sealing strip 100 for being arranged between the vehicle door glass and the interior trim panel, a B-pillar sealing strip for being arranged between the sheet metal and the B-pillar decorative panel, and a connecting portion 300 respectively connected to the glass sealing strip 100 and the B-pillar sealing strip. The glass sealing strip 100, the B-pillar sealing strip and the connecting portion 300 are integrally formed into a monolithic structure. The B-pillar sealing strip includes an X-direction sealing lip 210 for press-sealing with the vehicle door glass. The glass sealing strip 100 includes a Y-direction sealing lip 110 arranged away from the X-direction sealing lip 210 for press-sealing with the vehicle door glass, and a Y-direction sealing lip 2 120 arranged on the Y-direction sealing lip 110 and close to the X-direction sealing lip 210 for press-sealing with the vehicle door glass. The connecting portion 300 includes a supporting rib 310 connected to and supporting the Y-direction sealing lip 120.

[0029] like Figure 3 and Figure 4 As shown, specifically, the cross-sectional structure of the composite sealing strip of the present invention is as follows: the glass sealing strip 100 is arranged between the door glass and the interior panel, and the B-pillar sealing strip is arranged between the sheet metal and the B-pillar decorative panel, and then the glass sealing strip 100 and the B-pillar sealing strip are connected respectively through the connecting portion 300, so that the glass sealing strip 100, the B-pillar sealing strip and the connecting portion 300 are integrally formed into an integral structure, ensuring a simple and beautiful appearance; the X-direction sealing lip 210 on the B-pillar sealing strip is pressed and sealed with the door glass, and the Y-direction sealing lip on the glass sealing strip 100 is pressed and sealed with the door glass. The first 110 and the Y-direction sealing lip second 120 are pressed and sealed with the door glass to achieve X-direction and Y-direction sealing of the door glass, so as to ensure that the sealing strip is dynamically matched with the lifting and lowering of the door glass and improve the sealing performance; the Y-direction sealing lip second 120 is connected and supported by the supporting ribs on the connecting part 300 to squeeze the Y-direction sealing lip second 120 while ensuring the overall structure is compact and reliable, thereby improving the sealing performance of the Y-direction sealing lip second 120 on the door glass; compared with the existing technology, this solution has a simple and beautiful appearance, good sealing performance, strong practicality, and is suitable for wide promotion and application.

[0030] like Figure 4As shown, in this embodiment, the end of the connecting portion 300 facing the Y-direction sealing lip 2 120 is provided with a tooth-shaped protrusion 320 for abutting the door glass. Specifically, the tooth-shaped protrusion 320 abuts the door glass, converting surface contact into line contact, thereby reducing gaps and improving the sealing effect. At the same time, multiple vibration-absorbing and sound-insulating cavities are formed to isolate noise and vibration from outside the vehicle.

[0031] like Figure 4 As shown, in this embodiment, the glass sealing strip 100 and the connecting portion 300 enclose a soundproof chamber 400. Specifically, the soundproof chamber 400 provides a buffer during sound transmission, dissipating energy as sound travels through different media, thereby achieving sound insulation and noise reduction. It should be understood that the Y-direction sealing lip 120 and the supporting ribs 310 form part of the walls of the soundproof chamber 400.

[0032] like Figure 4 As shown, in this embodiment, the connecting portion 300 further includes a clamping groove 330 for clamping the sheet metal. Specifically, the sheet metal is clamped by the clamping groove 330 to fix the connecting portion 300 on the sheet metal, thereby ensuring reliable installation of the sealing strip.

[0033] like Figure 4 As shown, in this embodiment, the glass sealing strip 100 is further provided with a decorative lip 130 that extends away from the door glass and overlaps the interior trim panel. Specifically, the decorative lip 130 overlaps the interior trim panel so that the interior trim panel bends the sealing strip toward the door glass. The decorative lip 130 allows the exposed portion of the sealing strip to be integrated with the door, forming a decorative element. This prevents the sealing strip from being obtrusive and affecting the door's appearance.

[0034] like Figure 4 As shown, in this embodiment, the decorative lip 130 is provided with a spherical protrusion 131 on the end surface facing the interior panel. Specifically, the spherical protrusion 131 allows the decorative lip 130 to be pulled out when it is pressed by the interior panel, thereby avoiding being pressed by the interior panel.

[0035] like Figure 4As shown, in this embodiment, the Y-direction sealing lip 110 and the Y-direction sealing lip 2 120 are both arranged in an arc shape and are both inclined toward the X-direction sealing lip 210 . Specifically, the Y-direction sealing lip 110 and the Y-direction sealing lip 2 120 are both arranged in an arc shape so that the fitting angle changes accordingly when the door glass moves, and the Y-direction sealing lip 2 120, the door glass and the X-direction sealing lip 210 are enclosed to form a cavity for water conduction and sound insulation, so that after the external flowing water enters between the X-direction sealing lip 210 and the door glass, it is guided and discharged through the cavity, and the cavity structure allows the sound to propagate on different media and consume energy, so as to achieve the effect of sound insulation and noise reduction; the Y-direction sealing lip 1 10, the Y-direction sealing lip 2 120 and the door glass can also be enclosed to form a cavity for water conduction and sound insulation, so that after the external flowing water enters between the X-direction sealing lip 210 and the door glass, it is guided and discharged through the cavity, and the cavity structure allows the sound to propagate on different media and consume energy, so as to achieve the effect of sound insulation and noise reduction.

[0036] like Figure 4 As shown, in this embodiment, the B-pillar sealing strip is further provided with a clip 220 for being inserted between the sheet metal and the B-pillar decorative plate. Specifically, the B-pillar sealing strip is inserted between the sheet metal and the B-pillar decorative plate through the clip 220 to achieve reliable assembly of the sealing strip.

[0037] The frameless vehicle door of this embodiment includes the composite sealing strip cross-sectional structure described above. Specifically, by employing the composite sealing strip cross-sectional structure in the frameless vehicle door, the frameless vehicle door maintains a simple and aesthetically pleasing appearance while also improving its internal sealing performance, thereby enhancing its waterproof and noise reduction performance.

[0038] The automobile of this embodiment includes the above-mentioned frameless doors. Specifically, by adopting the above-mentioned frameless doors in the automobile, the appearance quality of the automobile can be improved while ensuring the performance.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
