Description

Technical Field

[0001] The invention relates to the technical field of automobile doors, and in particular to a zero-face difference door sealing system. Background Art

[0002] The door is an important part of the vehicle. It not only provides a passage for passengers to enter and exit the vehicle, but also undertakes functions such as protecting passenger safety, sound insulation, and heat insulation. Modern door design focuses on ergonomics to ensure easy opening and closing, while using lightweight materials to improve fuel efficiency. The interior of the door is usually equipped with an anti-collision beam to enhance the safety of side collisions. In addition, some models are also equipped with a smart key system that allows keyless entry and start, improving convenience and safety.

[0003] Among them, doors and windows are important components of vehicles. Doors are installed on the body shell through hinges. They not only provide a passage for passengers to enter and exit, but also have the function of sealing and isolating noise, and to a certain extent reduce side impacts to protect passengers. The structure of the door is relatively complex, including the door outer panel, the door inner panel, the door reinforcement beam (anti-collision beam), the door reinforcement plate, the door window frame, and the window. The window usually uses curved glass that is conducive to vision, embedded in the window frame or glued with adhesive to ensure a clear view, which is crucial for driving safety. The window glass can be moved for natural ventilation. The window glass is mainly guided by the guide rails set vertically in the door to move, and sealing materials are installed between the window glass and the guide rails to improve the sealing. The structural design of the door and window must meet the requirements of vision, ventilation, sealing and safety.

[0004] In order to take into account the appearance of current car doors while ensuring the sealing effect, zero-order difference framed car doors have come into being. For example, a zero-order difference car door system with application number CN202221375054.2 has the following technical points: it includes a mounting seat and a lifter, the mounting seat includes a lower base and an upper frame arranged thereon, the upper frame is divided into a fixed corner window mounting position and a movable glass mounting position; the lifter is arranged on the lower base, wherein: a zero-order difference corner window is arranged in the fixed corner window mounting position; the movable glass mounting position The position includes two door pillars, which are respectively a first door pillar and a second door pillar. A first guide rail sealing strip is arranged beside the first door pillar, a decorative panel is arranged on the outside of the second door pillar, and a second guide rail sealing strip is arranged on the inner side of the decorative panel. A moving glass assembly driven by a lifter is installed in the moving glass installation position. The moving glass assembly consists of a moving glass and at least one first double-material injection-molded slider and at least one second double-material injection-molded slider arranged on both side edges thereof. The first double-material injection-molded slider and the second double-material injection-molded slider are both supported and pasted. The first double-injection-molded slider comprises a supporting pasting surface portion and an arc-shaped sliding portion injected thereon; the supporting pasting surface portion of the first double-injection-molded slider comprises a pasting portion and a Y-direction positioning portion connected thereto, and a plurality of arc-shaped sliding portions are injection-molded on the Y-direction positioning portion; the pasting portion of the first double-injection-molded slider is pasted on one side edge of the inner side of the movable glass, and the Y-direction positioning portion of the first double-injection-molded slider is located in the first guide rail sealing strip; the supporting pasting surface portion of the second double-injection-molded slider comprises a pasting portion and an X-direction positioning portion and a Y-direction positioning portion connected thereto, and the X-direction positioning portion and A plurality of arc-shaped sliding parts are respectively injection-molded on the Y-direction positioning part; the adhesive part of the second double-material injection-molded slider is adhered to the other side edge of the inner side of the movable glass, and the X-direction positioning part and the Y-direction positioning part of the second double-material injection-molded slider are respectively located in the second guide rail sealing strip; during the lifting and lowering process of the movable glass, the first double-material injection-molded slider, the first guide rail sealing strip, the second double-material injection-molded slider and the second guide rail sealing strip are used to limit the X-direction and Y-direction trajectories; the outer surface of the movable glass is respectively flush with the outer surface of the corner window glass of the zero-face difference angle window and the outer surface of the decorative panel.

[0005] The above technical solution solves the problem of Y-direction step surface difference between the traditional automobile stamping and rolling window frame door structure and the various assembly components on the side of the body and the A-side shape of the movable glass, and improves the appearance effect. It effectively reduces the drag coefficient, reduces wind resistance noise, ensures NVH performance, enhances the Y-direction and X-direction limit during the lifting and lowering of the movable glass, ensures the position stability during the lifting and lowering of the movable glass, ensures the uniform sealing force between the sealing lip of the sealing strip and the glass, and ensures good sealing.

[0006] However, the current zero-face difference door systems only rely on the guide groove sealing strip and the sealing lip to perform unilateral sealing on the movable glass. Although this can form a zero-face difference door structure, for the car window, the sealing of the movable glass is not just a waterproof seal in the window frame position. When the horizontal height of the movable glass is lower than the waistline, it is also necessary to prevent water from entering the gaps between the movable glass and the guide groove sealing strip, and between the movable glass and the sealing lip, so as to prevent rainwater from entering the internal structure of the car door through these places and spreading in the internal structure of the car door, thereby causing water ingress and moisture in the car door.

[0007] Therefore, a zero-face difference door sealing system is proposed to solve or alleviate the above problems. Summary of the invention

[0011] Preferably, a slider with a circular cross-section is slidably connected inside the inner guide rail, a connecting strip is fixedly connected to one side of the slider, a sheet-shaped connecting piece is fixedly connected to the side of the connecting strip away from the slider, a sealing strip is fixedly connected to the end face of the connecting piece, the sealing strip can be used to fixedly contact with the end face of the movable glass, and the sealing strip and the inner waterproof plate are respectively used to be arranged on both sides of the movable glass.

[0012] Preferably, the inner guide rail is fixedly connected to a side away from the inner waterproof board with an upper water retaining plate in strip shape and in contact with the interior trim strip, and the lower waterproof guide rail frame is fixedly connected to a lower water retaining plate located below the upper water retaining plate, and the lower water retaining plate also in contact with the interior trim strip.

[0013] Preferably, the cross-section of the interior trim strip is U-shaped, and a plurality of inner lips are fixedly connected to one side of the inner circle of the interior trim strip, and the interior trim strip clamps and fixes the upper reinforcing plate and the lower reinforcing plate through the plurality of inner lips.

[0014] Preferably, the inner ring of the upper waterproof guide rail frame is fixedly connected to an inner supporting edge located above the inner bottom surface of the connecting bracket, and the inner ring of the inner supporting edge forms a channel for the slider and the connecting strip to move.

[0015] Preferably, a guide groove is provided at the upper end of the inner supporting edge located at the outer ring of the channel, and the cross-sectional area of ​​the through groove opening located at the guide groove is gradually reduced from top to bottom.

[0016] Preferably, the outer upper waterproof plate includes an outer upper main waterproof portion in an arc shape, and the outer lower waterproof plate includes an outer lower main waterproof portion in an arc shape with a cross-sectional shape identical to that of the outer upper main waterproof portion.

[0017] Preferably, the outer upper waterproof plate also includes an outer upper auxiliary waterproof part in an arc shape, and the arc length of the outer upper auxiliary waterproof part is smaller than the arc length of the outer upper main waterproof part.

At the same time, during the up and down displacement of the movable glass, the movable glass is connected to the connecting piece through the sealing strip, and during this process, the connecting piece drives the slider to slide in the inner guide rail. Since the cross section of the slider is circular, when it slides in the inner guide rail, the resistance during its displacement can be appropriately reduced, so that the movable glass can not only be sealed when it is displaced, but also slide more stably and is not prone to shaking. At the same time, due to the smaller resistance, there will be no excessive jamming during displacement. Since the interior trim strip and the inner waterproof board are an integrated long strip structure, not a split type, there is no gap in the middle compared to the conventional structure, so the inner waterproof board can have better sealing when in contact with the movable glass. The upper connecting rail, the upper waterproof guide rail frame, the connecting bracket, and the plastic bracket make the structure easier to produce, form, and assemble in a split form. The above-mentioned structures can ensure that the end face of the movable glass can have a good sealing effect in the vehicle door during the upward and downward displacement. When the movable glass is embedded below the waistline of the vehicle door, the movable glass can be embedded between the inner waterproof plate and the outer upper waterproof plate as well as the outer lower waterproof plate, so as to contact the inner and outer end faces of the movable glass through the three. Even if rainwater leaks downward between the guide rail and the movable glass, the inner waterproof plate and the outer upper waterproof plate as well as the outer lower waterproof plate can block the rainwater and prevent the rainwater from spreading toward other structures in the vehicle door, thereby ensuring the sealing effect of the vehicle door and preventing it from being damaged by moisture.

An upper reinforcing plate 7 is fixedly connected to one side of the upper connecting rail 5. A lower reinforcing plate spaced below the upper reinforcing plate 7 is fixedly connected to the plastic bracket 2. The interior strip 8 is in the shape of a long strip, and the interior strip 8 is sleeved on the outer sides of the upper reinforcing plate 7 and the lower reinforcing plate. The side of the interior strip 8 facing the outer upper waterproof plate 11 and the outer lower waterproof plate 22 is fixedly connected with the inner waterproof plate 10, and the inner waterproof plate 10 is set to be the same length as the interior strip 8; The inner waterproof board 10 , the outer upper waterproof board 11 and the outer lower waterproof board 22 all have elastic deformation performance, and a space for the movable glass 1 to move can be formed between the outer upper waterproof board 11 , the outer lower waterproof board 22 and the inner waterproof board 10 .

[0030] The plastic bracket 2 and the connecting bracket 3 are installed in the vehicle door, and both are located below the waistline of the vehicle door. Both mainly play the role of supporting and fixing other structures, and can also receive and discharge rainwater. The upper waterproof guide rail frame 4 is mainly used to play a receiving effect. When the plastic bracket 2 and the connecting bracket 3 are connected to the upper connecting rail 5, the structure of the outer upper waterproof plate 11 is added at the same time, so that the upper end of the outer lower waterproof plate 22 of the upper and lower reinforcing plates of the plastic bracket 2 is lengthened, so that the upper end of the outer upper waterproof plate 11 can extend to the upper end of the connecting bracket 3, so as to avoid the movable glass 1 from leaking at the connection when the upper connecting rail 5 is connected to the connecting bracket 3. The upper outer waterproof plate 11 and the lower outer waterproof plate 22 on the waterproof guide rail frame 4 and the lower waterproof guide rail frame can prevent rainwater flowing in between the movable glass 1 and the guide rail from spreading toward other structures in the vehicle door. Similarly, the interior trim strip 8 and the inner waterproof plate 10 fixedly connected thereto can cooperate with the upper outer waterproof plate 11 and the outer lower waterproof plate 22 to further block rainwater entering between the movable glass 1 and the guide rail to prevent rainwater from spreading toward other structures in the vehicle door. In addition, the interior trim strip 8 and the inner waterproof plate 10 fixedly connected thereto can also seal the movable glass 1 and the window frame when the movable glass 1 closes the window, thereby ensuring the sealing effect when the movable glass 1 is closed.

[0031] Preferably, if Figure 3 and Figure 5 As shown, a convex strip 6 is fixedly connected to the inner side of the upper connecting rail 5, an inner mounting strip 14 matching the cross section of the convex strip 6 is arranged inside the upper connecting rail 5, the inner mounting strip 14 is fixedly connected to an inner guide rail strip 15, and the inner guide rail strip 15 is fixedly connected to an inner waterproof board 16 that can be used to contact the end face of the movable glass 1.

[0034] Since the cross section of the slider 18 is circular, the contact area can be reduced as much as possible when the slider 18 slides in the inner guide rail 15, thereby reducing the resistance generated when the slider 18 slides, making the slider 18 smoother when following the displacement of the moving glass 1. The setting of the sealing strip 21 ensures better sealing between the end face of the moving glass 1 and the connecting piece 20 when connected.

[0035] Preferably, the inner guide rail 15 is fixedly connected to the side away from the inner waterproof board 16 with an upper water retaining plate 17 in strip shape and in contact with the interior trim strip 8, and the lower waterproof guide rail frame is fixedly connected to a lower water retaining plate 27 located below the upper water retaining plate 17, and the lower water retaining plate 27 also in contact with the interior trim strip 8.

[0036] The upper water retaining plate 17 and the lower water retaining plate 27 are provided to be able to interfere with the interior trim strip 8, so that even if the interior trim strip 8 leaks at the connection between the upper reinforcing plate 7 and the lower reinforcing plate, it can still be blocked by the upper water retaining plate 17 and the lower water retaining plate 27 to prevent rainwater from spreading toward other structures in the vehicle door.

[0037] Preferably, the cross-section of the interior trim strip 8 is U-shaped, and a plurality of inner lips 9 are fixedly connected to one side of the inner circle of the interior trim strip 8 , and the interior trim strip 8 clamps and fixes the upper reinforcing plate 7 and the lower reinforcing plate through the plurality of inner lips 9 .

[0038] When the interior trim strip 8 needs to be connected to the upper reinforcing plate 7 and the lower reinforcing plate, the upper reinforcing plate 7 and the lower reinforcing plate can be clamped by the inner lip 9, thereby increasing the connection strength of the interior trim strip 8 during installation.

[0039] Preferably, the inner circle of the upper waterproof guide rail frame 4 is fixedly connected to an inner support edge 25 located above the inner bottom surface of the connecting bracket 3, and the inner circle of the inner support edge 25 forms a channel for the slider 18 and the connecting strip 19 to move.

[0040] The inner supporting edge 25 is used to support the upper waterproof guide rail frame 4 .

[0041] Preferably, a guide groove 26 is provided at the upper end of the inner supporting edge 25 located at the outer ring of the channel, and the cross-sectional area of ​​the through groove opening at the guide groove 26 is gradually reduced from top to bottom.

[0042] The guide groove 26 is provided so that when the slider 18 moves downward following the moving glass 1 , the slider 18 can be guided by the guide groove 26 , so that the slider 18 can slide more smoothly through the joints connecting the upper connecting rail 5 , the connecting bracket 3 , and the plastic bracket 2 .

[0043] Preferably, the outer upper waterproof plate 11 includes an arc-shaped outer upper main waterproof portion 12 , and the outer lower waterproof plate 22 includes an arc-shaped outer lower main waterproof portion 23 with the same cross-sectional shape as that of the outer upper main waterproof portion 12 .

The outer lower waterproof plate 22 also includes an outer lower auxiliary waterproof portion 24 in an arc shape and with the same cross-sectional shape as the outer upper auxiliary waterproof portion 13. The cross-section of the outer lower auxiliary waterproof portion 24 is the same as that of the outer upper auxiliary waterproof portion 13. The outer lower auxiliary waterproof portion 24 and the outer upper auxiliary waterproof portion 13 are both fitted with one side of the plastic bracket 2 and the connecting bracket 3.

[0045] Preferably, a movable glass 1 is further included, and the connecting piece 20 is fixedly connected to the movable glass 1 via a sealing strip 21 .

[0046] The present invention is applied to a zero-face difference vehicle door, so that the movable glass 1 is in close contact with the waterproof board, which can effectively seal and prevent rainwater leakage. When the movable glass 1 moves up and down, through the cooperation of the sealing strip 21 and the connecting piece 20, the slider 18 slides in the guide rail to reduce resistance, ensure the smooth displacement of the movable glass 1, and reduce jamming. The interior trim strip 8 and the inner waterproof board 10 form an integrated structure to enhance the sealing effect, and the split design of the plastic bracket 2, the upper connecting rail 5 and other structures is convenient for production and assembly, and maintains the sealing of the vehicle door. When the movable glass 1 is submerged below the waistline, even if rainwater leaks, it can be effectively blocked to protect the vehicle door structure and avoid moisture damage.
