[0039] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0042] Generally, cars have sealing systems installed on their doors and windows to improve their airtightness and watertightness. The rear door fixed window is equipped with an edge sealing system and a window frame sealing strip system. The edge sealing system and the window frame sealing strip system work together to ensure the sealing and airtightness of the area.

[0043] In traditional car door systems, a cavity is formed between the edge seals, the interior sheet metal, and the glass guide rails formed by the window frame sealing strip system. Due to the gap between the edge seal system and the window frame sealing strip system, external airflow or water flow will enter the cavity along the gap, thereby affecting the waterproof and wind noise proof performance of the car doors and windows. In order to solve the above problems, traditional car door systems will set foam in the cavity and extrude the foam into the cavity. However, when setting the foam in the cavity, it is necessary to ensure sufficient compression to ensure the sealing effect, and due to manufacturing differences, the foam may fail to seal due to insufficient compression. In addition, the foam needs to be installed separately, which will increase the manual installation cost and reduce the installation efficiency.

[0044] Based on the above considerations, after in-depth research, a sealing structure was proposed, which can improve the waterproof and sealing performance of the car windows.

[0045] Figure 1 is a partial structural diagram of the sealing structure 10; Figure 2 A partial cross-sectional view of a schematic layout diagram of a car located at a fixed triangular window; Figure 3 for Figure 2 Middle AA section view; Figure 4 for Figure 2 Middle BB section view; Figure 5 It is a partial schematic diagram of the sealing structure 10.

[0046] Please refer to Figures 1 to 5 The sealing structure 10 includes an inner guide rail 100, an outer guide rail 200 and a corner window edging 400 arranged between the inner guide rail 100 and the outer guide rail 200. The inner guide rail 100, the outer guide rail 200 and the corner window edging 400 are arranged to form a glass run groove 300. The sealing structure 10 also includes a corner connector 500. At least part of the structure of the corner connector 500 is accommodated in the glass run groove 300 and is in contact with the corner window edging 400.

[0047] It should be noted that the inner guide rail 100 is closer to the interior of the vehicle, while the outer guide rail 200 is closer to the exterior of the vehicle. It is understood that during the manufacturing process, due to manufacturing tolerances, a slight gap may exist between the surfaces of the corner connector 500 and the corner window trim 400 even when they are properly fitted. However, within the tolerance range, they are still considered to be in a fitted state.

[0048] In the sealing structure 10, a glass run channel 300 is formed between the corner window edging 400, the inner guide rail 100 and the outer guide rail 200. Part of the structure of the corner connector 500 is accommodated in the glass run channel 300 and fits with the corner window edging 400 so that the gap between the corner connector 500 and the corner window edging 400 is sufficiently small, thereby improving the waterproof and wind noise proof performance, so that water is not easily infiltrated into the windows of the car when in use and the wind noise inside the car is low.

[0049] In addition, compared with the traditional door system in which foam is set in the cavity, the present application increases the end surface area of ​​the corner window edging 400, fits the end surface of the corner window edging 400 with the corner joint 500, and reduces the gap between the corner window edging 400 and the corner joint 500 to improve the waterproof and wind noise proof performance. From the installation perspective, the sealing structure 10 of the present application is more convenient to install.

[0050] Please refer to Figure 1 and Figure 4 The inner guide rail 100 and the outer guide rail 200 are arranged opposite to each other. The end of the inner guide rail 100 close to the corner window edge 400 defines the blocking end 110, and the end of the outer guide rail 200 close to the corner window edge 400 defines the entry end 210. Along the extension direction of the glass run channel 300, the blocking end 110 is higher than the entry end 210, that is, in Figure 4 In the middle L direction, the height of the blocking end 110 is higher than that of the entry end 210. At this time, even if water or air flows along the entry end 210 into the gap between the corner window edging 400 and the corner joint 500, it is difficult for water or air to pass through the inner guide rail 100 and enter the interior of the car due to the blocking end 110 and the gravity of the water flow. It is also difficult for air flow to pass through the blocking portion 114 and enter the interior of the car, thereby further improving the waterproof and wind noise resistance. Figure 1 The direction of the arrow.

[0051] It can be understood that, since the inner guide rail 100 , the outer guide rail 200 and the corner window edging 400 are jointly arranged to form the glass run channel 300 , the extension direction of the glass run channel 300 is consistent with the extension direction of the inner guide rail 100 .

[0052] Figure 6 is a partial cross-sectional view of a sealing structure 10 in another embodiment; Figure 7This is a partial cross-sectional view of the sealing structure 10 in another embodiment. Figure 6 and Figure 7 The corner joint 500 is further provided with an overlapping protrusion 510, which overlaps the end of the blocking end 110 or leaves a gap between the overlapping protrusion 510 and the end of the blocking end 110. Because the height of the blocking end 110 is higher than the height of the entry end 210, when air or water flows through the gap between the corner window edging 400 and the corner joint 500, it needs to pass over the blocking end 110 to enter the vehicle interior. In this case, the overlapping protrusion 510 is provided above the blocking end 110. Even if the pressure of the incoming water or air flow is relatively high, the overlapping protrusion 510 can provide a certain degree of blocking effect, preventing the air flow from passing over the blocking end 110 and entering the vehicle interior.

[0053] Specifically, the height difference between the blocking end 110 and the entry end 210 is 4-5 mm. The blocking end 110 can extend to abut against the overlapping protrusion 510, or there can be a gap between the blocking end 110 and the overlapping protrusion 510. The specific arrangement is set according to needs.

[0054] Please continue to refer to Figure 6 In some embodiments, the end of the blocking end 110 includes an overlapping portion 112 and a blocking portion 114. The blocking portion 114 is connected to the overlapping portion 112 and extends away from the overlapping portion 112. An installation space 116 is formed between the overlapping portion 112 and the blocking portion 114. The overlapping protrusion 510 is disposed within the installation space 116 and overlaps with the overlapping portion 112 or leaves a gap between the overlapping portion 112. In this way, even if water or air flows out through the gap between the overlapping portion 112 and the overlapping protrusion 510, it will be blocked by the blocking portion 114, thereby further improving the waterproof and wind noise resistance.

[0055] Please refer to Figure 6 and Figure 7 The blocking portion 114 is a raised structure, and the overlapping protrusion 510 is arranged opposite to the blocking portion 114. The overlapping protrusion 510 and the blocking portion 114 are arranged opposite to each other. Figure 6 and Figure 7 There is an overlapping part in the M direction. The extended length of the blocking portion 114 is set according to the specific requirements of waterproof and wind noise prevention. Please refer to Figure 6 In this embodiment, the blocking portion 114 extends to abut against the interior panel 600 .

[0056] Figure 8 A schematic diagram of a partial structure of a sealing structure 10 in another embodiment; Figure 9 A schematic diagram of a partial structure of a sealing structure 10 in another embodiment; Figure 10 This is a partial cross-sectional view of the sealing structure 10 in another embodiment. Figures 8 to 10In some embodiments, in order to improve the sealing between the corner connector 500 and the corner window edging 400, the surfaces between the corner connector 500 and the corner window edging 400 that are in contact with each other are set to be curved surfaces. Furthermore, even if there is a gap between the surfaces between the corner connector 500 and the corner window edging 400 that are in contact with each other due to manufacturing tolerances, the gap is also a curved gap. Compared with setting the corner connector 500 and the corner window edging 400 to be in contact with each other in a flat manner, the flow channel formed by the curved gap is longer. When air or water flows in the curved gap, due to the longer flow time, it is easier to fall under the action of gravity and be discharged to the outside along the glass run groove 300.

[0057] For details, please refer to Figures 8 to 10 In some embodiments, the surface of the corner connector 500 facing the corner window trim 400 is a first curved surface 520, and the surface of the corner window trim 400 facing the corner connector 500 is a second curved surface 410. The corner connector 500 is attached to the corner window trim 400 by affixing the first curved surface 520 and the second curved surface 410. Thus, when the first curved surface 520 and the second curved surface 410 are attached, even if a gap is created between the first curved surface 520 and the second curved surface 410 due to manufacturing tolerances, the gap is a curved gap, thereby improving the waterproof and wind noise resistance between the first curved surface 520 and the second curved surface 410.

[0058] Optionally, the first zigzag surface 520 and the second zigzag surface 410 are both step surfaces, wherein the number of steps forming the step surface can be set as needed, and can be one step or more than two steps.

[0059] Please refer back Figure 1 and Figure 4 In some embodiments, the corner window edging 400 includes an edging body 420 and an abutment body 430 formed on the circumferential side wall of the edging body 420. The end of the abutment body 430 away from the edging body 420 is used to abut against the door frame trim 700, and the end faces of the abutment body 430 and the edging body 420 facing the corner joint 500 are both in contact with the corner joint 500.

[0060] Please refer to Figure 1 and Figure 4 There are two abutting bodies 430, and the two abutting bodies 430 are arranged along the circumference of the edging body 420. The end of the abutting body 430 away from the edging body 420 is used to abut against the upper door frame trim 700, and the end face of the abutting body 430 and the edging body 420 facing the corner joint 500 is in contact with the corner joint 500.

[0061] Since the contact area between the abutment 430 and the corner joint 500 is small and the strength of the abutment 430 is low, when faced with high pressure from water flow or air flow, the abutment 430 near the inner guide rail 100 is prone to deformation, thereby affecting the sealing performance there.

[0062] Figure 11 A schematic diagram of a partial structure of a sealing structure 10 in another embodiment; Figure 12 A partial cross-sectional view of a layout diagram of a vehicle at a fixed triangular window in another embodiment; Figure 13 for Figure 12 Based on the above problems, in some embodiments, please refer to Figure 11 and Figure 13 The corner joint 500 is also provided with a supporting protrusion 530. When the corner joint 500 is in contact with the corner window edging 400, the supporting protrusion 530 is arranged below one of the two abutting bodies 430 close to the inner guide rail 100, and the positive projection of the abutting body 430 close to the inner guide rail 100 toward the supporting protrusion 530 at least partially falls on the supporting protrusion 530. In this way, the supporting protrusion 530 can directly abut the abutting body 430 or be arranged below the abutting body 430 and form a gap with the abutting body 430. When the abutting body 430 is deformed, the supporting protrusion 530 can play the role of supporting the abutting body 430. At the same time, when the abutting body 430 is placed on the supporting protrusion 530, the supporting protrusion 530 can also play a certain sealing role, blocking airflow or water flow to the interior of the car.

[0063] Please refer to Figure 13 The projection direction of the orthographic projection of the abutting body 430 close to the inner guide rail 100 toward the supporting protrusion 530 is the H direction.

[0064] Please refer to Figure 14 , Figure 14 This is a partial structural diagram of the sealing structure 10 in another embodiment. In other embodiments, the corner window edging 400 also includes a reinforcing body 440. The reinforcing body 440 is used to connect the abutting body 430 and the surface of the edging body 420 facing the corner joint 500. The side of the reinforcing body 440 facing the corner joint 500 is in contact with the corner joint 500.

[0065] Please refer to Figure 14There are two abutting bodies 430, and the two abutting bodies 430 are arranged along the circumference of the edging body 420. The reinforcing body 440 is connected between the two abutting bodies 430, and the end surface of the reinforcing body 440 facing the corner connector 500 is in contact with the corner connector 500. In this way, the reinforcing body 440 can improve the strength of the abutting body 430, and prevent the abutting body 430 from being deformed under the impact of water flow or air flow, which affects the sealing between the abutting body 430 and the corner connector 500. In addition, the end surface of the reinforcing body 440 facing the corner connector 500 is in contact with the corner connector 500, which increases the contact area between the corner connector 500 and the corner window edging 400. To a certain extent, the shell improves the sealing between the corner connector 500 and the corner window edging 400.

[0066] Please refer to Figure 14 The abutting body 430 is in the shape of a long strip and extends along the length direction of the edging body 420. The length direction of the edging body 420 is Figure 14 In the M direction, the reinforcing body 440 is provided at one end of the abutting body 430 close to the corner joint 500, and the reinforcing body 440 is a plate-shaped structure.

[0067] In addition, the present application also relates to a window glass assembly, including the sealing structure 10 in any of the aforementioned embodiments; and also including a window glass 20 , wherein the window glass 20 is mounted on an outer guide rail 200 .

[0068] In addition, the present application also relates to a car, comprising the window glass assembly according to any of the aforementioned embodiments.

[0069] The above-mentioned glass assembly and automobile both include the aforementioned sealing structure 10. The aforementioned sealing structure 10 is formed by surrounding the corner window edging 400, the inner guide rail 100 and the outer guide rail 200 to form a glass run groove 300, and the corner connector 500 is set in the glass run groove 300. At this time, the corner connector 500 is fitted with the side wall of the corner window edging 400 located in the glass run groove 300, so that the gap between the corner connector 500 and the corner window edging 400 is sufficiently small, thereby improving the waterproof and wind noise proof performance, so that water is not easy to enter the windows of the automobile when in use and the wind noise inside the automobile is low.
