Description

Technical Field

[0001] This utility model relates to the field of vehicle door sealing technology, and in particular to an easy-to-install zero-surface-difference vehicle door sealing system. Background Technology

[0002] Car doors are a crucial component of a vehicle, affecting not only its appearance but also playing a vital role in safety and practicality. Generally, the primary function of car doors is to provide access for passengers, while also sealing the cabin and isolating it from external noise and dust during operation. Modern car door designs increasingly emphasize user-friendliness and intelligence, featuring electric opening and closing functions. With the simple press of a button or operation via a smart key, the doors open and close automatically, greatly enhancing convenience. In terms of materials, car doors are typically made of high-strength steel or aluminum alloy to ensure sufficient strength and durability, while also reducing vehicle weight to some extent. Car door designs are also diverse, with different car models featuring unique styling based on their style and positioning. From the streamlined doors of sporty sedans to the wide, heavy doors of luxury SUVs, each showcases the unique charm of the vehicle.

[0003] The zero-face-difference door is an advanced automotive door design. Its core feature is that the door assembly is flush with all the side assemblies and the A-side of the sliding glass, achieving a zero-face-difference effect. This design not only enhances the overall aesthetics and appearance of the vehicle but also effectively reduces the drag coefficient and wind noise, improving the vehicle's aerodynamic performance. The zero-face-difference door system optimizes the limiting structure during glass operation, ensuring the positional stability of the sliding glass and making the sealing force between the weatherstripping and the glass more uniform, further improving the vehicle's airtightness and quietness. Compared to traditional door systems, the zero-face-difference door requires higher manufacturing and assembly precision, while also reducing the step difference in side component matching, thus improving the overall quality of the door.

[0004] For example, a zero-face difference car door system with application number CN202221375054.2 in the prior art has the following technical points: it includes a mounting base and a lifter. The mounting base includes a lower base and an upper frame set on it. The upper frame is divided into a fixed corner window mounting position and a movable glass mounting position. The lifter is set on the lower base. The key feature is that a zero-face difference corner window is provided in the fixed corner window mounting position. The movable glass mounting position includes two door pillars, namely a first door pillar and a second door pillar. A first guide rail sealing strip is provided next to the first door pillar. A trim panel is provided on the outside of the second door pillar. A second guide rail sealing strip is provided on the inside of the trim panel. A movable glass assembly driven by the lifter is installed in the movable glass mounting position. The movable glass assembly consists of a movable glass and at least one first double-material injection molding slider and at least one second double-material injection molding slider respectively provided on its two side edges. The first double-material injection molding slider and the second double-material injection molding slider are both composed of a supporting adhesive surface and an arc-shaped sliding part injected on it. The first double-material injection molded slider has a support bonding surface including a bonding part and a Y-direction positioning part connected thereto. The Y-direction positioning part has several arc-shaped sliding parts injection molded on it. The bonding part of the first double-material injection molded slider is bonded to one edge of the inner side of the movable glass, and the Y-direction positioning part of the first double-material injection molded slider is located inside the first guide rail sealing strip. The second double-material injection molded slider has a support bonding surface including a bonding part and X-direction positioning parts and Y-direction positioning parts connected thereto. The X-direction positioning parts and Y-direction positioning parts have several arc-shaped sliding parts injection molded on them respectively. The bonding part of the second double-material injection molded slider is bonded to the other edge of the inner side of the movable glass, and the X-direction positioning parts and Y-direction positioning parts of the second double-material injection molded slider are located inside the second guide rail sealing strip respectively. During the lifting and lowering 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 limit the X-direction and Y-direction trajectories. The outer surface of the movable glass is flush with the outer surface of the corner window glass of the zero-plane difference corner window and the outer surface of the decorative panel, respectively.

[0005] As can be seen from the above, current zero-face difference car doors typically use a guide rail sealing strip next to the door pillar and a slider that slides within the guide rail sealing strip and connects to the door glass. However, the current guide rail sealing strip is installed inside the guide rail. Specifically, the zero-face difference corner window adopts an integrated injection-molded edge-sealed zero-face difference corner window, which consists of a guide rail sealing strip installed inside the guide rail and corner window glass integrated onto it through an edge-sealing injection molding process; the first guide rail sealing strip is installed inside the guide rail of the zero-face difference corner window, and the first guide rail sealing strip is provided with a hook. The guide rail is provided with a locking platform that matches the hook. The first guide rail sealing strip is locked inside the guide rail, and the guide rail sealing strip is made of TPV and EPDM materials.

[0006] However, because the guide rail sealing strip uses a high hardness of SHA80 or higher, it is easy for the guide rail sealing strip and the guide rail to collide, squeeze and rub against each other during assembly. This not only makes it difficult to assemble the entire structure, but also causes damage between the structures, which may lead to water leakage in the internal structure of the zero-surface difference door. However, if the guide rail sealing strip is made of a soft material, it may not be able to be firmly installed in the guide rail. Therefore, it is necessary to improve the current guide rail sealing strip and guide rail structure to reduce the assembly difficulty while still ensuring its sealing effect.

[0007] Therefore, an easy-to-install zero-surface-difference door sealing system is proposed to solve or alleviate the above problems. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easy-to-install zero-surface-difference door sealing system.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An easy-to-install zero-surface-difference door sealing system includes a lower guide rail, an upper guide rail disposed at the upper end of the lower guide rail, a water-blocking strip installed on one side of the lower guide rail, a guide rail sealing strip that can be embedded in the upper and lower guide rails, and a sliding column slidably connected in the guide rail sealing strip. The sliding column is fixedly connected to a slider that can be connected to the glass. The guide rail sealing strip has elastic deformation properties and is made of TPV material with a Shore hardness of less than 70 degrees.

[0011] Preferably, one side of the guide rail sealing strip has two sets of outwardly protruding limiting parts, which prevent the guide rail sealing strip from leaving when the guide rail sealing strip is embedded between the upper guide rail and the lower guide rail.

[0012] Preferably, the inner rings of the upper and lower guide rails are each fixedly connected with two limiting protrusions, the distance between adjacent limiting protrusions is less than the maximum distance between the two sets of limiting parts, and the guide rail sealing strips located between the two sets of limiting parts are fixedly connected with an elastic part that abuts against the inner rings of the upper and lower guide rails.

[0013] Preferably, the guide rail sealing strip has a hook portion integrally formed on the side away from the limiting part. When the guide rail sealing strip is embedded in the upper and lower guide rails, the hook portion is embedded in the upper and lower guide rails, and the hook portion prevents the guide rail sealing strip from leaving.

[0014] Preferably, both the inner rings of the upper and lower guide rails are fixedly connected with obstructing protrusions, which are positioned on the movement path of the hook portion when it leaves the upper and lower guide rails.

[0015] Preferably, the guide rail sealing strip has an outer bubble tube portion extending to the outer side of the upper and lower guide rails fixedly connected to the side near the limiting part, and an inner lip portion extending to the outer side of the upper and lower guide rails fixedly connected to the side near the hook portion.

[0016] Preferably, the guide rail sealing strip has an outer lip extending to the outer side of the upper and lower guide rails fixedly connected to the side near the limiting part, and an inner lip extending to the outer side of the upper and lower guide rails fixedly connected to the side near the hook part.

[0017] Preferably, the outer ring of the guide rail sealing strip is fixedly connected with several protrusions that abut against the inner rings of the upper and lower guide rails.

[0018] Preferably, the length of the guide rail sealing strip is equal to the sum of the lengths of the lower guide rail and the upper guide rail.

[0019] This utility model has the following beneficial effects:

[0020] During assembly, the guide rail sealing strip is first embedded between the upper and lower guide rails. The elastic part enters the guide rail and deforms, and the spacing between the limiting parts decreases before entering the limiting protrusion. Next, pressing the other side causes the hook part to deform and enter the obstructing protrusion, ultimately securing the guide rail sealing strip firmly into the guide rail. Since the length of the guide rail sealing strip is equal to the total length of the upper and lower guide rails, it effectively blocks rainwater, preventing it from flowing into the car door. This design reduces assembly difficulty and allows for the replacement of different sealing strips as needed to ensure waterproofing. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0033] An easy-to-install zero-surface-difference door sealing system, such as Figure 1 and Figure 2 As shown, it includes a lower guide rail 1, an upper guide rail 3 set at the upper end of the lower guide rail 1, a water-blocking strip 2 installed on one side of the lower guide rail 1, a guide rail sealing strip 401 that can be embedded in the upper guide rail 3 and the lower guide rail 1, and a sliding post 501 slidably connected in the guide rail sealing strip 401. The sliding post 501 is fixedly connected to a slider 502 that can be connected to the glass. The guide rail sealing strip 401 has elastic deformation properties. The guide rail sealing strip 401 is made of TPV material with a Shore hardness of less than 70 degrees. The length of the guide rail sealing strip 401 is equal to the sum of the lengths of the lower guide rail 1 and the upper guide rail 3.

[0034] One side of the guide rail sealing strip 401 has two sets of outwardly protruding limiting parts 403 integrally formed. When the guide rail sealing strip 401 is embedded between the upper guide rail 3 and the lower guide rail 1, the limiting parts 403 prevent the guide rail sealing strip 401 from leaving. The inner rings of the upper guide rail 3 and the lower guide rail 1 are fixedly connected to two limiting protrusions 301. The distance between adjacent limiting protrusions 301 is less than the maximum distance between the two sets of limiting parts 403. The guide rail sealing strip 401 located between the two sets of limiting parts 403 is fixedly connected to an elastic part 404 that abuts against the inner rings of the upper guide rail 3 and the lower guide rail 1.

[0035] The guide rail sealing strip 401 has a hook portion 405 integrally formed on the side away from the limiting part 403. When the guide rail sealing strip 401 is embedded in the upper guide rail 3 and the lower guide rail 1, the hook portion 405 is embedded in the upper guide rail 3 and the lower guide rail 1, and the hook portion 405 prevents the guide rail sealing strip 401 from leaving. The inner rings of the upper guide rail 3 and the lower guide rail 1 are fixedly connected with obstructing protrusions 302. The obstructing protrusions 302 are set on the movement path of the hook portion 405 when it leaves the upper guide rail 3 and the lower guide rail 1.

[0036] The guide rail sealing strip 401 has an outer bubble tube portion 4061 that extends to the outer side of the upper guide rail 3 and the lower guide rail 1 fixedly connected to the side near the limiting portion 403. The guide rail sealing strip 401 has an inner lip portion 407 that extends to the outer side of the upper guide rail 3 and the lower guide rail 1 fixedly connected to the side near the hook portion 405. The outer ring of the guide rail sealing strip 401 has a plurality of protrusions 402 that abut against the inner ring of the upper guide rail 3 and the lower guide rail 1 fixedly connected to it. Example 2:

[0037] The difference from Example 1 is that,

[0038] like Figure 3 and Figure 4 As shown, the guide rail sealing strip 401 has an outer lip 4062 that extends to the outer side of the upper guide rail 3 and the lower guide rail 1 fixedly connected to the side near the limiting part 403, and an inner lip 407 that extends to the outer side of the upper guide rail 3 and the lower guide rail 1 fixedly connected to the side near the hook part 405.

[0039] In actual assembly, the guide rail sealing strip 401 is first embedded between the upper guide rail 3 and the lower guide rail 1. Specifically, when embedding the guide rail sealing strip 401 between the upper guide rail 3 and the lower guide rail 1, the elastic part 404 is first allowed to enter the upper guide rail 3 and the lower guide rail 1. Then, the guide rail sealing strip 401 is squeezed, causing the elastic part 404 to undergo elastic deformation. This causes the limiting part 403 to undergo elastic deformation, thereby reducing the distance between the two sets of limiting parts 403. As a result, the two sets of limiting parts 403 can enter between the limiting protrusions 301. In this way, one side of the guide rail sealing strip 401 can be embedded between the upper guide rail 3 and the lower guide rail 1. Then, the assembler only needs to press the other side of the guide rail sealing strip 401, causing the hook part 405 to undergo elastic deformation, and then the hook part 405 enters into the obstructing protrusion 302. In this way, the guide rail sealing strip 401 is embedded between the upper guide rail 3 and the lower guide rail 1. Both sides of the seal 401 can be embedded into the upper guide rail 3 and the lower guide rail 1. At this time, the elastic part 404 can also release elastic potential energy, which causes the hook part 405 to press against the obstruction protrusion 302, so that the guide rail seal 401 is firmly set in the upper guide rail 3 and the lower guide rail 1, and it is not easy to fall off. In addition, since the length of the guide rail seal 401 is equal to the sum of the lengths of the lower guide rail 1 and the upper guide rail 3, when rainwater flows with the glass box slider 502 and the sliding column 501, the guide rail seal 401 can block the rainwater and prevent rainwater from entering other structures of the door. Due to the above structure, the assembly difficulty of the zero-surface difference door sealing system is lower. If the actual application needs are different, two different guide rail seals 401 can be replaced, so that the outer lip part 4062 or the outer bubble tube part 4061 on the guide rail seal 401 can be replaced, thereby ensuring its waterproof effect.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
