Description

Technical Field

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

[0002] With increasingly sophisticated aesthetic demands and fiercer competition in the automotive market, frameless doors are becoming more and more common. Frameless doors, with their borderless windows, offer a more sporty and youthful appearance compared to traditional framed doors, giving them a premium, cool, and minimalist feel. As a significant innovation in automotive design, the sealing structure of frameless doors directly impacts a vehicle's sound insulation, waterproofing, and aerodynamic performance.

[0003] In related technologies, the sealing strip structure consists of two parts: an inner extruded strip and an outer extruded strip. The inner and outer extruded strips are respectively assembled onto the side sheet metal stop and the side metal guide rail. The inner and outer extruded strips are joined together by their lips to achieve the waterproof and soundproofing function of the sealing strip. However, this structural form requires the extrusion, cutting, and assembly of the inner and outer extruded strips separately, which consumes more energy, has higher manufacturing costs, poorer sealing performance, and low parts assembly efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a frameless door sealing structure and vehicle, which can reduce manufacturing costs, reduce energy consumption, and improve sealing performance and parts assembly efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A frameless car door sealing structure, comprising:

[0007] Side panel sheet metal, side exterior trim panel and side guide rail, the combination of side exterior trim panel and side guide rail is set on the side panel sheet metal;

[0008] The side sealing strip includes a first sealing part, a second sealing part, and a connecting part. Both the first sealing part and the second sealing part are connected to the connecting part, and the connecting part can be snapped and fixed to the combination of the side outer trim panel and the side guide rail.

[0009] During the process of closing the car window, the upper edge of the car window is pressed and sealed with the first sealing part, and the second sealing part is pressed and sealed with the inner wall of the car window.

[0010] Preferably, the side rail is located inside the outer side panel, and the connecting part can slide along the inner wall of the side rail in the cross-sectional direction and engage with the side rail.

[0011] Preferably, one of the connecting part and the side rail is provided with a slot, and the other of the connecting part and the side rail is provided with a protrusion, which engages with the slot.

[0012] Preferably, the connecting part is provided with a stress groove, which extends along the length of the connecting part and is located on the side of the connecting part away from the side rail.

[0013] Preferably, the connecting part is provided with a pressure relief groove, which extends along the length direction of the connecting part and is located on the side of the connecting part near the side guide rail.

[0014] Preferably, the frameless door sealing structure also includes a side interior panel, and the second sealing part includes a first lip and a second lip. The first lip can be squeezed and sealed with the window glass, and the second lip can abut against the side interior panel.

[0015] Preferably, the first sealing part is a thin-walled structure, and the first sealing part is connected to the connecting part and encloses to form a first bubble; the second sealing part is a hollow columnar structure, and a second bubble is provided inside the second sealing part.

[0016] Preferably, the connecting part is made of solid adhesive or micro-foamed solid adhesive.

[0017] Preferably, the first sealing part, the second sealing part, and the connecting part are integrally formed structural components.

[0018] A vehicle comprising a frameless door sealing structure including any of the above-described technical solutions.

[0019] The beneficial effects of this utility model are:

[0020] This utility model provides a frameless door sealing structure and vehicle. When the window glass is raised and closed, its upper edge is pressed against the first sealing part of the side sealing strip, forming a first sealing barrier. Simultaneously, the inner wall of the window glass comes into close contact with and is pressed against the second sealing part, forming a second seal. The connecting part is fixed by snapping with the combination of the side outer trim panel and the side guide rail, ensuring the overall position of the sealing strip is stable, thereby achieving a double sealing effect. The double sealing is achieved through a single sealing strip, eliminating the need for additional independent sealing components. Compared with existing separately extruded inner and outer extruded strips, this replaces the lip-fitting between the inner and outer extruded strips, reducing energy consumption and manufacturing costs. At the same time, the connecting part keeps the bottom of the entire side sealing strip section continuous, providing a simple appearance and structure, reducing the risk of water leakage, strengthening the sealing effect, and improving the assembly efficiency of the parts.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] like Figure 1As shown, an embodiment of this utility model provides a frameless car door sealing structure, including a side panel 7, a side outer trim panel 8, a side guide rail 6, a side sealing strip, and a car window glass 10. The combination of the side outer trim panel 8 and the side guide rail 6 is disposed on the side panel 7. The side sealing strip includes a first sealing part 4, a second sealing part 5, and a connecting part 1. The first sealing part 4 and the second sealing part 5 are both connected to the connecting part 1. The connecting part 1 can be snapped and fixed to the combination of the side outer trim panel 8 and the side guide rail 6. During the process of the car window glass 10 rising and closing, the upper edge of the car window glass 10 is pressed and sealed with the first sealing part 4, and the second sealing part 5 is pressed and sealed with the inner sidewall of the car window glass 10.

[0028] When the window glass 10 is raised and closed, its upper edge is pressed against the first sealing part 4 of the side sealing strip, forming the first sealing barrier. Simultaneously, the inner wall of the window glass 10 is in close contact with and pressed against the second sealing part 5, forming the second seal. The connecting part 1 is fixed by snapping together with the combination of the side outer trim panel 8 and the side guide rail 6, ensuring the overall position of the sealing strip is stable, thus achieving a double sealing effect. This double sealing is achieved through a single sealing strip, eliminating the need for additional independent sealing components. Compared to existing separately extruded inner and outer extruded strips, this replaces the lip-fitting between the inner and outer extruded strips, reducing energy consumption and manufacturing costs. Furthermore, the connecting part 1 ensures the bottom of the entire side sealing strip cross-section remains continuous, providing a clean appearance and structure, reducing the risk of leakage, enhancing the sealing effect, and improving the assembly efficiency of the parts.

[0029] Preferably, the first sealing part 4, the second sealing part 5, and the connecting part 1 are integrally molded structural components. This design avoids the material waste associated with traditional multi-segment sealing strips, further reducing material costs. Specifically, the first sealing part 4, the second sealing part 5, and the connecting part 1 are integrally molded using dual-material injection molding.

[0030] Furthermore, the side guide rail 6 is located inside the side outer trim panel 8, and the connecting part 1 can slide along the inner wall of the side guide rail 6 in the cross-sectional direction and engage with the side guide rail 6.

[0031] During the installation of the side sealing strip, first press the second sealing part 5 to assemble it onto the side sheet metal 7, and continue to press the first sealing part 4. The connecting part 1 will undergo elastic deformation and slide along the inner wall of the side guide rail 6 in the cross-sectional direction. With this setting, the connecting part 1 can be snapped and fixed with the side guide rail 6, thereby completing the assembly between the sealing strip and the vehicle body.

[0032] The side sealing strip is fixed to the vehicle body by a snap-fit ​​method, which can be assembled without the aid of tools, saving assembly time and improving assembly efficiency.

[0033] Furthermore, one of the connecting part 1 and the side guide rail 6 is provided with a slot, and the other of the connecting part 1 and the side guide rail 6 is provided with a protrusion, which engages with the slot. Specifically, the protrusion is in the shape of a claw.

[0034] The groove and the protrusion of the card form a mechanical locking structure, which can limit the axial movement and radial rotation of the connecting part 1 along the side guide rail 6, and ensure the stable compression contact between the first sealing part 4, the second sealing part 5 and the window glass 10, avoiding sealing failure due to loose connection.

[0035] For example, such as Figure 1 As shown, the side guide rail 6 is provided with a slot, and the connecting part 1 is provided with a protrusion. The protrusion engages with the slot, and with this arrangement, the sealing strip is extruded through the protrusion, facilitating processing and production. In other embodiments, the side guide rail 6 may also have a protrusion, and the connecting part 1 may have a slot.

[0036] Furthermore, the connecting part 1 is made of solid adhesive or micro-foamed solid adhesive. Solid adhesive or micro-foamed solid adhesive has high hardness and resistance to deformation. When the connecting part 1 made of it engages with the side guide rail 6, it provides a more stable clamping force, preventing the sealing strip from loosening due to vibration during vehicle operation. Understandably, micro-foamed solid adhesive, through physical or chemical foaming processes, forms uniformly distributed micro-bubbles within the adhesive material, significantly reducing material density. This allows for the manufacture of lightweight sealing strips, greatly reducing material usage costs.

[0037] Specifically, the connecting part 1 is made of EPDM rubber. EPDM rubber has excellent weather resistance and aging resistance. As a key connecting component between the sealing strip and the side guide rail 6, the connecting part 1 is exposed to the external environment for a long time. The anti-aging properties of EPDM rubber can extend the service life of the sealing structure and reduce the sealing failure caused by material cracking and hardening.

[0038] Furthermore, the connecting part 1 is provided with a stress groove 2, which extends along the length direction of the connecting part 1 and is located on the side of the connecting part 1 away from the side rail 6.

[0039] By setting a stress groove 2 inside the connecting part 1, the cross-section can naturally form an "opening angle" during extrusion. With this setting, the die does not need to be designed with a complex pre-deformation compensation structure, which can improve the stability of the extrusion process, increase extrusion efficiency, and reduce costs.

[0040] When the window glass 10 repeatedly presses against the first sealing part 4 and the second sealing part 5, the stress groove 2 can absorb the impact energy through local deformation, thereby dispersing the stress in the connecting part 1 and improving fatigue life.

[0041] Furthermore, the connecting part 1 is provided with a pressure relief groove 3, which extends along the length direction of the connecting part 1 and is located on the side of the connecting part 1 near the side guide rail 6.

[0042] The pressure relief groove 3 extends along the length of the connecting part 1 and is close to the side guide rail 6. During actual vehicle assembly, by pressing the second sealing part 5 and the first sealing part 4, the area of ​​the pressure relief groove 3 on the connecting part 1 will undergo elastic deformation. When the connecting part 1 is fully inserted into the side guide rail 6, the pressure relief groove 3 elastically resets, and the connecting part 1 will slide along the cross-sectional direction within the side guide rail 6, achieving precise engagement between the protrusion and the groove, and the side sealing strip is then positioned. This process transforms the traditional "hard-squeeze" assembly into an "elastic adaptive" assembly, which can quickly achieve the assembly between the sealing strip and the vehicle body, avoiding damage to the sealing strip caused by forced installation.

[0043] Furthermore, the frameless door sealing structure also includes a side interior panel 9, and the second sealing part 5 includes a first lip and a second lip. The first lip can be squeezed and sealed with the window glass 10, and the second lip can abut against the side interior panel 9.

[0044] The first lip of the second sealing part 5 is pressed against the inner wall of the window glass 10 to form a seal, and the second lip abuts against the side interior panel 9 to form a seal. Combined with the seal between the first sealing part 4 and the upper edge of the window glass 10, they form a "triple protection" that effectively blocks rainwater, dust and external noise from intruding.

[0045] Furthermore, the first sealing part 4 has a thin-walled structure, and the first sealing part 4 is connected to the connecting part 1 and encloses it to form a first bubble; the second sealing part 5 has a hollow columnar structure, and a second bubble is provided inside the second sealing part 5.

[0046] During the closing process of the car window glass 10, when the upper edge of the car window glass 10 presses against the first sealing part 4, the first bubble inside provides sufficient deformation space through elastic contraction, which can absorb the instantaneous extrusion force, make the contact pressure evenly distributed, and ensure that the fit gap between the upper edge of the car window glass 10 and the first sealing part 4 is small, which can effectively block the intrusion of rainwater and dust; when the first lip of the second sealing part 5 is pressed against the inner wall of the car window glass 10, the second bubble will deform, and at the same time, the second bubble will reset and provide force to the first lip, so that the first lip is in close contact with the inner wall of the car window glass 10, effectively improving the sealing performance.

[0047] An embodiment of this utility model provides a vehicle including the frameless door sealing structure described above.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
