The door weather strip structure may be applied to both a front door and a rear door. Taking the example that the door seal strip structure is used for a front door, the door seal strip structure on the front door on the left side of the vehicle (for short, the left front door) and the door seal strip structure on the front door on the right side of the vehicle (for short, the right front door) are generally symmetrically arranged, for example, fig. 1 is a schematic structural view of a side of the left front door, where the door seal strip structure faces to the outside of the vehicle, and fig. 2 is a schematic structural view of a side of the right front door, where the door seal strip structure faces to the inside of the vehicle.

Specifically, the inner water cutting 1 and the first sealing member 2 are usually made of rubber or plastic and have certain elasticity, and the inner water cutting 1 and the first sealing member 2 are usually integrally formed by an integral molding process. The inner water cutter 1 is of a strip-shaped structure and extends and is arranged along the front-rear direction of the vehicle, the inner water cutter 1 is usually arranged at the lower frame of a window frame of the vehicle door for installing the vehicle door glass and is positioned at the inner side of the vehicle door glass (namely, one side of the vehicle door glass positioned in the vehicle), and is sealed by being extruded with the vehicle door glass, and the inner water cutter 1 is usually matched with the outer water cutter so as to scrape residual water on the vehicle door glass when the vehicle door glass descends, prevent the residual water from entering the inner space of the vehicle door, and simultaneously play a sound insulation role. When the door seal strip structure is applied to a front door, the first sealing member 2 is connected to the front end of the inside water cut 1, at this time, the second sealing member 3 (described later) is used for sealing the rear triangular window area of the rear door glass, and the first sealing member 2 is positioned at the rear side of the B-pillar seal strip, and when the door is closed, the front end of the first sealing member 2 is sealed with the rear end of the B-pillar seal strip in a pressing manner; when the door sealing strip structure is applied to a rear door, the first sealing element 2 is connected to the rear end of the inner water cutter 1, at this time, the second sealing element 3 is used for sealing a front triangular window area of front door glass, and the first sealing element 2 is located on the front side of the B-pillar sealing strip, and when the door is closed, the rear end of the first sealing element 2 is used for extruding and sealing with the front end of the B-pillar sealing strip. Meanwhile, the first sealing member 2 is provided to extend downward beyond the inner cut 1 to seal an assembly gap of the door inner space, wherein the assembly gap of the door inner space generally refers to a gap formed by assembly between respective constituent parts of the door, such as an assembly gap between a door trim panel and a door glass, between a door outer panel and a door glass, between a door trim panel and a door inner panel, between a door inner panel and a door outer panel, and between a door weather strip structure and a door inner panel or door trim panel, while the inner cut 1 generally serves to seal an assembly gap between a door inner panel and a door glass, and the first sealing member 2 generally serves to seal an assembly gap formed between a door trim panel and a door inner panel.

The door weather strip structure in this embodiment may be applied to both front and rear doors. Specifically, the lower frame of the window frame for mounting the door glass can be sealed by arranging the inner water cut 1, so that not only can the residual water on the door glass be prevented from entering the inner space of the door, but also the door gap at the door glass can be reduced, and the leakage wind noise of the door at the door glass can be reduced; simultaneously, through setting up first sealing member 2 in the one end that interior water cut 1 to with the sealing connection between door sealing strip structure and the B post sealing strip of vehicle is realized to first sealing member 2 and the B post sealing strip extrusion seal when the door is closed, moreover, through making first sealing member 2 downwardly extending setting, with sealed the assembly gap between door inner space's for example door plaque and the door inner panel, reduce the conduction of door cavity noise, thereby can further reduce the leakage wind noise of door, improve the security of driving experience sense and driving. Moreover, through the integral connection of the inner water cutter 1 and the first sealing piece 2, the inner water cutter 1 and the first sealing piece 2 are integrated together, so that the number of parts can be reduced, the assembly process is simplified, and the lap joint gap between the inner water cutter 1 and the first sealing piece 2 can be avoided, thereby reducing leakage wind noise caused by the lap joint gap.

Further, as shown in fig. 1 and 7, the side of the inner water cut 1 facing the door glass of the vehicle is provided with a first seal lip 11 and a second seal lip 12, and the first seal lip 11 and the second seal lip 12 are arranged in parallel and spaced apart in the vertical direction.

In this embodiment, the first sealing lip 11 and the second sealing lip 12 are generally soft rubber structures with a certain elasticity, and can be deformed adaptively according to the cavity structure of the door gap, so as to realize automatic random sealing. In this way, when the door sealing strip structure is assembled on the door, the first sealing lip 11 and the second sealing lip 12 of the inner water seal 1 form extrusion sealing with the door glass, so that an assembly gap at the lower end of the door glass is sealed, and the leakage air noise of the door is reduced.

Further, the sum of the projection height of the first seal lip 11 and the projection height of the second seal lip 12 is generally set between 15mm and 45 mm. Wherein the raised height of the first seal lip 11 refers to the dimension of the first seal lip 11 in the thickness direction of the inside water cut 1, the raised height of the second seal lip 12 refers to the dimension of the second seal lip 12 in the thickness direction of the inside water cut 1, and the thickness direction of the inside water cut 1 is the Y-axis direction or a direction substantially parallel to the Y-axis in fig. 7.

And the shape of the first seal rib 22 is adapted to the shape of the reinforcing rib structure at the corresponding position on the door inner panel, so that the first seal rib 22 can form lap seal with the reinforcing rib structure of the door inner panel.

In this embodiment, the first rib 221 is disposed at the edge of the lower end of the first sealing body 21, and/or the second rib 222 is disposed at the side of the first sealing body 21 facing the vehicle exterior, so that the first rib 221 and/or the second rib 222 are used to seal the assembly gap of the vehicle door inner space, thereby ensuring the effectiveness of the first sealing member 2 in sealing; in addition, the first ribs 221 and/or the second ribs 222 may further improve the structural strength of the first seal 2, and prolong the service life of the first seal 2.

Alternatively, as shown in fig. 4, the first rib 221 has a first end and a second end that are disposed opposite to each other, and the first rib 221 is gradually far away from the first sealing body 21 along a direction from the first end to the second end, where the first end of the first rib 221 is connected to the first sealing body 21; and/or, the second rib 222 has a first end and a second end disposed opposite to each other, and the second rib 222 is gradually far away from the first sealing body 21 along a direction from the first end to the second end, where the first end of the second rib 222 is connected to the first sealing body 21.

In this embodiment, the first end of the first rib 221 is connected to the first sealing body 21, the second end of the first rib 221 is gradually far away from the first sealing body 21 upwards, so that the first rib 221 is integrally inclined towards the upper side, the first end of the second rib 222 is connected to the first sealing body 21, the second end of the second rib 222 is gradually far away from the first sealing body 21 downwards, so that the second rib 222 is integrally inclined towards the lower side, and the second rib 222 can be selectively arranged on one side of the first sealing body 21 towards the door glass or on one side of the first sealing body 21 away from the door glass according to actual needs (as shown in fig. 4). In this way, the first rib 221 is obliquely arranged towards the upper side and/or the second rib 222 is obliquely arranged towards the lower side, so that the first rib 221 and/or the second rib 222 can seal the assembly gap of the inner space of the vehicle door, the first rib 221 and/or the second rib 222 can be adapted to the assembly gap with different sizes, and the adaptability of the assembly gap of the first rib 221 and/or the second rib 222 and the inner space of the vehicle door is improved.

Optionally, the first bead 221 has a dimension in the thickness direction of the first sealing body 21 of between 1mm and 5mm, and/or the second bead 222 has a dimension in the thickness direction of the first sealing body 21 of between 5mm and 20 mm. The thickness direction of the first sealing body 21 is perpendicular to the surface of the first sealing body 21, but since the first sealing body 21 is generally curved as shown in fig. 4, the thickness direction of the first sealing body 21 can be understood as the Y-axis direction or the direction substantially parallel to the Y-axis in fig. 4.

The dimension of the first bead 221 in the thickness direction of the first seal body 21 (hereinafter, simply referred to as the height of the first bead 221) may be understood as a dimension of the first bead 221 exceeding the first seal body 21 in the thickness direction of the first seal body 21, and for example, the height of the first bead 221 may be selected to be 1mm, 2mm, 3mm, 4mm, 5mm, or the like. The dimension of the second rib 222 in the thickness direction of the first seal body 21 (hereinafter simply referred to as the height of the second rib 222) may be understood as the dimension of the second rib 2222 in the thickness direction of the first seal body 21, and for example, the height of the second rib 222 may be selectively set to 5mm, 10mm, 15mm, 20mm, or the like.

In this embodiment, since the first bead 221 is generally used to seal the assembly gap between the first seal body 21 and the door inner panel/door trim, and the assembly gap is generally relatively small, the height of the first bead 221 is set between 1mm and 5mm, so that the first bead 221 can be ensured to match the assembly gap of the door inner space without occupying too much of the door inner space, and extrusion sealing is achieved. The second rib 222 is generally used for lap-sealing with the reinforcing rib structure on the inner door panel, and the reinforcing rib structure of the inner door panel generally has a certain width, so that the height of the second rib 222 is set between 5mm and 20mm, so that a certain interference amount is ensured between the second rib 222 and the reinforcing rib structure on the inner door panel, and a seal can be formed through lap-joint, and further the sealing effect is ensured.

Further, the cross-sectional shape of the first sealing rib 22 is rectangular, triangular, or a combination of rectangular and triangular. The arrangement is such that the structure of the first seal rib 22 is simplified, and the processing and the manufacturing are facilitated.

Optionally, as shown in fig. 1 and 2, the door seal structure further includes a second sealing member 3, and the second sealing member 3 is integrally connected to an end of the inner water seal 1 remote from the first sealing member 2, and is used for sealing a triangular window area of the door glass.

Specifically, the second sealing member 3 is generally made of rubber or plastic with a certain elasticity, and the second sealing member 3 and the inner water cutter 1 are generally integrally connected by an integral molding process. When the vehicle door sealing strip structure is applied to a front vehicle door, the first sealing element 2 and the second sealing element 3 are respectively connected with the front end and the rear end of the inner water seal 1 in an integrated mode, the first sealing element 1 is used for extruding and sealing with the front end of the B-pillar sealing strip, and the second sealing element 3 is used for sealing a front triangular window area of front and rear vehicle door glass; when the door sealing strip structure is applied to a rear door, the first sealing element 2 and the second sealing element 3 are respectively connected with the rear end and the front end of the inner water seal 1 in an integrated mode, the first sealing element 1 is used for extruding and sealing with the rear end of the B-pillar sealing strip, and the second sealing element 3 is used for sealing a rear triangular window area of rear door glass.

Because the triangular window area of the door glass is the area most sensitive to wind noise, especially the triangular window area of the front door glass, if the upper cavity and the lower cavity of the door (namely the cavity where the door glass is positioned and the cavity below the door glass) are communicated at the triangular window area, the noise of the cavity of the door is mutually conducted, even amplified, and the leakage wind noise of the door is larger. Therefore, in the embodiment, the second sealing element 3 is arranged at one end of the inner water cut 1 far away from the first sealing element 1 so as to seal and insulate the triangular window area of the door glass, and the upper cavity and the lower cavity of the door are prevented from being communicated at the triangular window area, so that the conduction of the noise of the cavity of the door is reduced, and the leakage air noise of the door is further reduced; moreover, by integrally connecting the second sealing member 3 with the inner water cutter 1 so that the second sealing member 3 is integrated with the inner water cutter 1, not only the number of parts can be further reduced and the assembly process can be simplified, but also the formation of a lap joint gap between the second sealing member 3 and the inner water cutter 1 can be avoided, thereby further reducing the leakage wind noise generated by the lap joint gap.

Optionally, as shown in fig. 5 and 6, the second sealing member 3 includes a second sealing body 31 and a second sealing rib 32, the second sealing body 31 is connected to an end of the inner water seal 1 remote from the first sealing member 2, the second sealing rib 32 is used for pressing and sealing with a trim panel of the triangular window area, and the second sealing rib 32 includes a third rib 321 and/or a fourth rib 322, the third rib 321 is disposed around an edge of the second sealing body 31, and the fourth rib 322 is connected to a side of the second sealing body 31 facing the vehicle interior.

Specifically, the second seal body 31 is typically a sound insulating pad that is typically fitted to the triangular window area of the door glass to perform sealing and sound insulating functions. A triangular hole structure is generally provided on the door at a position corresponding to the triangular window area, the second sealing body 31 is used for sealing the triangular hole structure, the fourth rib 322 of the second sealing rib 32 is disposed around the edge of the triangular hole structure, and the third rib 321 of the second sealing rib 32 is disposed around the edge of the second sealing body 31. When assembled, the third bead 321 and/or the fourth bead 322 of the second sealing bead 32 form a seal with the trim panel of the triangular window area by extrusion.

In this embodiment, the third rib 321 may be disposed on the edge of the second sealing body 31, so as to seal the assembly gap between the edge of the second sealing body 31 and the edge of the decorative board of the triangular window area by using the third rib 321, so as to reduce the leakage wind noise at the triangular window area of the door glass; by providing the fourth rib 322 on the side of the second sealing body 31 facing the vehicle interior, the fourth rib 322 is used to seal the internal assembly gap between the second sealing body 31 and the trim panel of the triangular window area, so as to further reduce the leakage wind noise at the triangular window area of the door glass.

Optionally, as shown in fig. 5 and 6, the second sealing rib 32 further includes a fifth rib 323, where the second sealing body 31 is provided with an opening 311, and the fifth rib 323 is disposed around an edge of the opening 311. In this manner, the circumferential gap of the opening 311 is sealed with the fifth bead 323, thereby reducing leakage wind noise at the opening 311.

Optionally, as shown in connection with fig. 5 and 6, the second seal member 3 further comprises a sealing strip 33, the sealing strip 33 being connected to the side of the second seal body 31 facing the inside water cut 1 and being used for sealing against a window rail.

In this embodiment, the shape of the sealing strip 33 is generally adapted to the window guide rail, and the door sealing strip structure is assembled on the front door, and if the front window guide rail is vertically arranged, the sealing strip 33 is also vertically arranged, and if the front window guide rail is obliquely arranged, the sealing strip 33 is also obliquely arranged, as shown in fig. 2. In this way, the sealing strip 33 is arranged on the side, facing the inner water cut 1, of the second sealing body 31 to seal the window guide rail, so that leakage wind noise of the vehicle door at the window guide rail is reduced.

Alternatively, the second seal bead 32 has a dimension in the thickness direction of the second seal body 31 of between 1mm and 4.5 mm. The thickness direction of the second sealing body 31 is perpendicular to the surface of the second sealing body 31, but since the second sealing body 31 is generally inclined as shown in fig. 6, the thickness direction of the second sealing body 31 can be understood as the Y-axis direction or the direction substantially parallel to the Y-axis in fig. 6.

In the case of the sealing beads (for example, the fourth bead 322 and the fifth bead 323) protruding from the surface of the second sealing body 31, the height of the second sealing bead 32 may be understood as the dimension of the second sealing bead 32 in the thickness direction of the second sealing body 31, and for example, the height of the fourth bead 322 may be selected to be 1mm to 4mm and the height of the fifth bead 323 may be selected to be 1.5mm to 4.5 mm. As for the sealing bead (e.g., the third bead 321) provided at the edge of the second sealing body 31, the height of the second sealing bead 32 may be understood as a dimension of the second sealing bead 32 exceeding the second sealing body 31 in the thickness direction of the second sealing body 31, and for example, the height of the third bead 321 may be optionally set between 1mm and 3 mm.

In this embodiment, the height of the second sealing rib 32 is set between 1mm and 4.5mm, so that a certain interference amount is ensured between the second sealing rib 32 and the triangular decorative plate in the triangular window area, and thus sealing can be formed by extrusion, and further sealing effect is ensured.

Further, the second seal bead 32 has a rectangular, triangular, or a combination of rectangular and triangular cross-sectional shapes. The arrangement is such that the structure of the second seal rib 32 is simplified, and the processing and the manufacturing are facilitated.
