In the prior art, as shown in FIG. 1B, the seal 10 is typically a simple lip extrusion, which is relatively soft in material and can be extruded. When the rear door is opened, the sealing member 10 is opened away from the rear triangular window 30, and when the rear door is closed, the sealing member 10 is closed to be in contact with the rear triangular window 30, is pressed between the rear triangular window 30 and the rear door fixing window 40, forms a single-layer seal between the rear triangular window 30 and the rear door fixing window 40, and has poor sealing property. And as shown in fig. 1B, the sealing member 10 is required to be installed upward from the lower side due to the U-shaped structure of the sealing member 10 when being connected with the glass run channel 20, and the door sealing member 60 is located just at the lower side, which limits the installation path of the sealing member 10, thereby inconvenient installation of the sealing member 10.
FIG. 2A is a schematic view of the external structure of a rear triangular window and a rear door fixing window according to the present invention; FIG. 2B is a cross-sectional view of FIG. 2A along B-B; fig. 2C is an enlarged view of region C in fig. 2B.
An aspect of the present invention provides a seal for a vehicle, fig. 2B shows a state in which a rear door is closed, and as can be seen from fig. 2B, the seal 100 is disposed between a rear triangular window 300 and a rear door fixing window 400 to form a seal between the rear triangular window 300 and the rear door fixing window 400 when the rear door is closed. On the other hand, the seal 100 is connected to the door frame 500 in the first direction, and further, the seal 100 is connected to the door inner panel 700 in the first direction. Also, the sealing member 100 is connected to the rear door fixing window. Accordingly, the sealing member 100 is coupled to the door frame 500, the door inner panel 700, and the rear door fixing window 400 so as to be movable together with the following doors, for example, the opening and closing of the following doors, and when the rear doors are opened, the sealing member 100 is away from the rear triangular window 300; when the rear door is closed, the sealing member 100 contacts the rear triangular window 300 and forms a double-layered seal between the rear triangular window 300 and the rear door fixing window 400, thereby increasing sealability between the rear triangular window 300 and the rear door fixing window 400. Also, as can be seen in fig. 2B, the seal 100 allows a smaller cavity between the rear triangular window 300 and the rear door fixing window 400, thereby further reducing noise. The seal 100 according to the present invention is easy to install since the surrounding environmental parts do not limit installation in the first direction, in particular, the door seal 600 does not block the first direction.
Specific structure of the seal 100 according to the present invention as shown in fig. 2C, the seal 100 includes a first structure 110 and a second structure 120 connected to each other, wherein the first structure 110 is disposed outside the second structure 120 for forming a seal between the rear triangular window 300 and the rear door fixing window 400, and the second structure 120 is for fixing the seal 100 to the rear door. Specifically, the first structure 110 is configured to: the first structure 110 may contact the rear triangular window 300 when the rear door is closed, and form a double seal between the rear triangular window 300 and the rear door fixing window 400. The double seal has better tightness, thereby reducing noise. The seal 100 is fixedly coupled to the rear door by the second structure 120, and in particular, the second structure 120 is fixedly coupled to the door frame 500 and the door inner panel 700 such that when the rear door is opened, the seal 100 is opened following the rear door, thereby being out of contact with the rear triangular window 300. Specifically, the second structure 120 is fixedly coupled to the door frame 500 and the door inner panel 700 in the first direction such that the installation path is not limited by surrounding parts, thereby facilitating installation.
The first structure 110 includes an arc portion 111 and two linear portions 112 formed by extending both ends of the arc portion 111 toward each other. Specifically, the arcuate portion 111 of the first structure 110 is configured to: when the rear door is closed, a double seal is formed between the rear triangular window 300 and the rear door fixing window 400. As shown in fig. 2C, in particular, the arc-shaped portion 111 may include a semicircle shape such that the arc-shaped portion 111 may have two opposite arc-shaped segments. As shown in fig. 4, when the rear door is closed such that the gap between the rear triangular window 300 and the rear door fixing window 400 is narrowed to press the arc portion 111 of the first structure 110, as shown by a dotted line in fig. 4, the arc portion 111 adjacent to the rear triangular window 300 is pressed to correspond to the shape of the rear triangular window 300, and an upper and lower double seal is formed between the rear triangular window 300 and the rear door fixing window 400 due to the opposite two arc segments of the arc portion 111. And the deformation of the sealing member 100 may reduce the cavity between the rear triangular window 300 and the rear door fixing window 400, not only may increase sealability, but also may reduce noise. Also, the extending direction of the two linear portions 112 is perpendicular to the first direction, i.e., the second structure is fixedly coupled to the door frame 500 and the door inner panel 700 in a direction perpendicular to the extending direction of the two linear portions 112, i.e., the first direction.
Also, two linear portions 112 are formed by extending both ends of the arc-shaped portion 111 toward each other. Specifically, the two linear portions 112 extend from both ends of the arc portion 111 in parallel to each other into the arc of the arc portion 111 to form two linear portions 112 parallel to each other and spaced apart from each other by a certain distance, as shown in fig. 2C, wherein one of the two linear portions 112 is connected with the second structure 120, and the other of the two linear portions 112 is connected with the rear door fixing window 400, that is, an opening is formed between the two linear portions 112, which can rapidly exhaust air in the cavity of the arc portion 111 outward when the sealing member is pressed, and is more advantageous for the arc portion 111 to deform between the rear triangular window 300 and the rear door fixing window 400 to better fit between the rear triangular window 300 and the rear door fixing window 400, thereby increasing sealability. Specifically, the linear portion 112 of the first structure 110 is integrally formed with the second structure 120 by two-shot molding. Because the first structure 110 has soft squeezable characteristics due to its structural characteristics, and the second structure 120 has rigid characteristics due to its need to be fixedly coupled to the door frame 500 and the door inner panel 700, the seal 100 is integrally formed using two materials having different hardness through a two-shot molding process, thereby coupling the linear portion 112 of the first structure 110 with the second structure 120. Wherein the injection molding material of the first structure 110 is softer and the injection molding material of the second structure 120 is harder. Due to the structural shape of the sealing member 100, the linear portion 112 is connected with the rear door fixing window 400 when the sealing member 100 is installed in the first direction.
Also, according to an embodiment of the present invention, the second structure 120 includes a first portion 121 and a second portion 122 parallel to each other, and a third portion 123 vertically disposed between the first portion 121 and the second portion 122 to connect the first portion 121 and the second portion 122. One end of the third portion 123 is located at an end of the first portion 121, and the other end of the third portion 123 is located at an intermediate position of the second portion 122. Wherein the first portion 121 is connected to the first structure and the second portion is connected to the door frame 500. As described above, the first portion 121 is integrally formed with the first structure 110 through a two-shot molding process, and the second portion 122 is fixedly coupled to the door frame 500 through the clip 130, and further, the second portion 122 is fixedly coupled to the door inner panel 700. Also, first portion 121 and second portion 122 are perpendicular to the first direction, and the mounting direction of clip 130 is perpendicular to second portion 122, i.e., parallel to the first direction, thereby effecting a secure attachment of second portion 122 to door frame 500 in the first direction. As shown in fig. 5, when the sealing member 100 is installed in the first direction, there are no parts around which limit the installation path of the sealing member 100, and in particular, the installation path of the sealing member 100 does not overlap with the door sealing member 600, thereby facilitating the installation of the sealing member 100.
Also, a soft sealing lip 1220 is provided at an end of the second portion 122 for connection to the rear door fixing window 500, and as shown in fig. 6, the soft sealing lip 1220 may be better adhered to the rear door fixing window 500, thereby improving NVH performance of the vehicle. On the other hand, a coating may be applied on the arc-shaped portion 111 of the first structure 110 to further reduce friction noise.
In the mounting, as shown in fig. 3, the clip 130 is first mounted on the second portion 122 of the second structure 120 of the sealing member 100, and then the sealing member 100 is fixedly connected to the glass run 200 by compression molding, wherein the compression molding process uses TPE, and the sealing member 100 mounted with the clip 130 is fixedly connected to the glass run 200 by compression molding using TPE, which may enhance the connection of the sealing member 100 to the glass run 200, and is simple and easy to operate. The rear door fixing window 400 is then installed at the outside, and the door frame 500 and the door inner panel 700 are installed at the inside, thereby forming a rear door product. Wherein the seal is fixedly attached to the door frame 500 and the door inner panel 700 by the clips 130.
The first structure 110 and the second structure 120 may be extruded bubble tube structures.
The invention further provides a vehicle, and the sealing element is provided with the scheme.
