[0002] Doors are a vital component of a vehicle. They not only provide access for passengers but also provide safety, sound insulation, and thermal insulation. Modern door designs prioritize ergonomics for easy opening and closing, while also utilizing lightweight materials to enhance fuel efficiency. Doors are often equipped with internal impact beams to enhance side impact safety. Furthermore, some models feature smart key systems, allowing for keyless entry and start, enhancing convenience and safety.

[0003] Doors and windows are crucial components of a vehicle. Hinged to the vehicle body, doors not only provide access for passengers but also provide a seal to isolate noise and mitigate side impacts, protecting occupants. The door structure is complex, consisting of an outer door panel, an inner door panel, a reinforcing crossbeam (anti-collision beam), a door reinforcement plate, a door window frame, and the window itself. Windows typically utilize curved glass to enhance visibility and are embedded in the frame or affixed with adhesive to ensure a clear field of view, which is crucial for driving safety. The window glass is movable to facilitate natural ventilation. The window glass is primarily guided by vertical rails within the door, with sealing material installed between the window glass and the rails to enhance sealing. The structural design of doors and windows must meet multiple requirements for visibility, ventilation, sealing, and safety.

[0004] In order to take into account the appearance of the current car doors while ensuring the sealing effect, zero-order-difference framed car doors have come into being. Among them, for example, a zero-face difference car door system with application number CN202221375054.2 has the following technical points: it includes a mounting seat and an elevator. 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 elevator is arranged on the lower base, wherein: a zero-face 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 the first door pillar and the second door pillar respectively. A first guide rail sealing strip is provided next to the first door pillar, a decorative panel is provided on the outside of the second door pillar, and a second guide rail sealing strip is provided on the inside of the decorative panel; a moving glass assembly driven by a lift is installed in the moving glass installation position, and the moving glass assembly consists of a moving glass and at least one first double-injection molded slider and at least one second double-injection molded slider provided on both side edges thereof, and the first double-injection molded slider and the second double-injection molded slider are both supported and pasted The supporting pasting surface portion of the first double-material injection-molded slider includes 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-material 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-material injection-molded slider is located in the first guide rail sealing strip; the supporting pasting surface portion of the second double-material injection-molded slider includes a pasting portion and an X-direction positioning portion and a Y-direction positioning portion connected thereto, and the X-direction positioning portion and Several arc-shaped sliding parts are injection-molded on the Y-direction positioning part; the adhesive part of the second double-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 Y-direction positioning part of the second double-injection-molded slider are respectively located in the second guide rail sealing strip; during the raising and lowering process of the movable glass, the first double-injection-molded slider, the first guide rail sealing strip, the second double-injection-molded slider and the second guide rail sealing strip are used to limit the X-direction and Y-direction tracks; the outer surface of the movable glass is flush with the outer surface of the corner window glass of the zero-face difference corner window and the outer surface of the decorative panel.

[0005] This technical solution addresses the Y-axis step difference between traditional stamped and rolled window frame and door structures, the body side assemblies, and the A-side styling of the sliding glass, improving the exterior appearance. It effectively reduces drag coefficient and wind noise, ensuring NVH performance. It also enhances the Y- and X-axis position limits during the sliding glass raising and lowering process, ensuring positional stability and a uniform sealing force between the sealing strip lip and the glass, ensuring a good seal.

[0006] However, the current zero-face difference door system relies solely on the guide groove sealing strip and the sealing lip to seal the movable glass on one side. Although this can form a zero-face difference door structure, for the window, the sealing of the movable glass is not just a waterproof seal at 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, to prevent rainwater from entering the internal structure of the door through these gaps and spreading in the internal structure of the door, thereby causing water ingress and moisture in the door.

[0007] Therefore, a zero-face difference vehicle door sealing system is proposed to solve or alleviate the above problems. Utility Model Content

[0027] When the utility model is actually applied in a zero-face difference vehicle door, the movable glass can still achieve sealing by being in contact with the inner waterproof plate and the inner waterproof plate, thereby preventing rainwater from leaking through the gaps on both sides of the door frame when it falls on the movable glass. At the same time, during the up and down displacement of the movable glass, the movable glass is connected to the connecting piece by the sealing strip, and during this process, the connecting piece drives the slider to slide in the inner guide bar. Since the cross-section of the slider is circular, when it slides in the inner guide bar, 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 less likely to shake. At the same time, due to the smaller resistance, there will be no excessive jamming during displacement.

[0028] Since the interior trim strip and the inner waterproofing plate are an integrated long strip structure rather than a separate structure, there is no gap between them compared to conventional structures. Therefore, the inner waterproofing plate can achieve better sealing when in contact with the movable glass. The arrangement of the upper connecting rail, the upper waterproof guide rail frame, the connecting bracket, and the plastic bracket makes this structure easier to produce, form, and assemble in a separate form. The arrangement of these structures can ensure that the end face of the movable glass can achieve a satisfactory sealing effect in the vehicle door during the upward and downward movement.

[0029] When the movable glass is embedded below the waistline of the car door, the movable glass can be embedded between the inner waterproof plate and the outer upper waterproof plate and the outer lower waterproof plate, and the three can contact the inner and outer end faces of the movable glass. Then, even if rainwater leaks downward between the guide rail and the movable glass, the inner waterproof plate and the outer upper waterproof plate and the outer lower waterproof plate can block the rainwater and prevent the rainwater from spreading toward other structures in the car door, thereby ensuring the sealing effect of the car door and preventing it from being damaged by moisture.

[0045] A zero-face difference door sealing system, such as Figures 1 to 7 Shown, including

[0046] The plastic bracket 2 is strip-shaped and open on one side along its length. The upper end of the plastic bracket 2 is integrally formed with a connection bracket 3 with an expanded opening;

[0047] The upper waterproof guide rail frame 4 is embedded in the connecting bracket 3, and one side of the upper waterproof guide rail frame 4 is fixedly connected to the outer upper waterproof plate 11 located below the waistline;

[0048] The lower waterproof guide rail frame is embedded in the plastic bracket 2 and is located below the upper waterproof guide rail frame 4. One side of the lower waterproof guide rail frame is fixedly connected to the outer lower waterproof plate 22 located below the outer upper waterproof plate 11;

[0049] The upper connecting rail 5 is embedded in the inner circle of the upper waterproof guide rail frame 4 and is located above the lower waterproof guide rail frame. One side of the upper connecting rail 5 is fixedly connected to the upper reinforcing plate 7. The plastic bracket 2 is fixedly connected to the lower reinforcing plate spaced below the upper reinforcing plate 7.

[0050] The interior strip 8 is in the shape of a long strip and is sleeved on the outer side of the upper reinforcement plate 7 and the lower reinforcement 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 to the inner waterproof plate 10. The inner waterproof plate 10 is set to the same length as the interior strip 8;

[0051] The inner waterproof board 10 , the outer upper waterproof board 11 and the outer lower waterproof board 22 all have elastic deformation properties, and a gap 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 .

[0052] The plastic bracket 2 and the connecting bracket 3 are installed in the car door, and both are located below the waistline of the car door. The two 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 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 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, preventing 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.

[0053] Preferably, if Figure 3 and Figure 5 As shown, the inner side of the upper connecting rail 5 is fixedly connected with a convex strip 6, and an inner mounting strip 14 matching the cross-section of the convex strip 6 is provided in the upper connecting rail 5. The inner mounting strip 14 is fixedly connected with an inner guide rail strip 15, and the inner guide rail strip 15 is fixedly connected with an inner waterproof board 16 that can be used to contact the end face of the movable glass 1.

[0054] By providing the convex strips 6, the connection strength of the inner mounting strip 14 when connected to the upper connecting rail 5 can be increased, making its installation more stable. The inner guide rail 15 fixedly connected to the inner mounting strip 14 can provide a guiding space for the displacement of the slider 18, and the inner waterproof plate 16 fixed to the inner guide rail 15 can add a barrier to rainwater on the movable glass 1.

[0055] Preferably, a slider 18 with a circular cross-section is slidably connected to the inner guide rail 15, a connecting strip 19 is fixedly connected to one side of the slider 18, a sheet-shaped connecting piece 20 is fixedly connected to the side of the connecting strip 19 away from the slider 18, and a sealing strip 21 is fixedly connected to the end face of the connecting piece 20. The sealing strip 21 can be used to make fixed contact with the end face of the movable glass 1, and the sealing strip 21 and the inner waterproof plate 16 are respectively used to be arranged on both sides of the movable glass 1.

[0056] Since the cross section of the slider 18 is circular, the contact area of ​​the slider 18 can be minimized as much as possible when sliding in the inner guide bar 15, thereby reducing the resistance generated by the sliding of the slider 18, making it smoother when the slider 18 follows the displacement of the moving glass 1. The provision of the sealing strip 21 ensures better sealing between the end face of the moving glass 1 and the connecting piece 20.

[0057] 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 a strip shape and in conflict 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 conflict with the interior trim strip 8.

[0058] The upper water baffle 17 and the lower water baffle 27 are set 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 baffle 17 and the lower water baffle 27 to prevent rainwater from spreading toward other structures inside the car door.

[0059] 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 .

[0060] 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.

[0061] Preferably, the inner circle of the upper waterproof guide rail frame 4 is fixedly connected to the 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 bar 19 to move.

[0062] Through the inner supporting edge 25 , it is able to provide support to the upper waterproof guide rail frame 4 .

[0063] 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 channel opening located at the guide groove 26 is gradually reduced from top to bottom.

[0064] The setting of the guide groove 26 allows the slider 18 to be guided by the guide groove 26 when following the downward displacement of the movable glass 1, so that the slider 18 can slide more smoothly through the joint connecting the upper connecting rail 5, the connecting bracket 3, and the plastic bracket 2.

[0065] 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 having the same cross-sectional shape as that of the outer upper main waterproof portion 12 .

[0066] The outer upper waterproof plate 11 also includes an outer upper auxiliary waterproof portion 13 in an arc shape, the arc length of the outer upper auxiliary waterproof portion 13 is smaller than the arc length of the outer upper main waterproof portion 12, and the outer lower waterproof plate 22 also includes an outer lower auxiliary waterproof portion 24 in an arc shape and 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 the cross-section 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 on one side of the plastic bracket 2 and the connecting bracket 3.

[0067] Preferably, a movable glass 1 is further included, and the connecting piece 20 is fixedly connected to the movable glass 1 through a sealing strip 21 .

[0068] The utility model 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, the slider 18 slides in the guide rail through the cooperation of the sealing strip 21 and the connecting piece 20, reducing resistance, ensuring smooth displacement of the movable glass 1, and reducing 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 structures such as the plastic bracket 2 and the upper connecting rail 5 is convenient for production and assembly, maintaining 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, protecting the vehicle door structure and avoiding damage due to moisture.

[0069] 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.
