[0032] The utility model provides a sealing component for a vehicle door, including an inner water cut 1 and a corner structure 2, the inner water cut 1 includes an inner water cut body 11 and a mounting portion 12 that are connected to each other, the mounting portion 12 is mounted on an inner panel 100 of the vehicle door, the corner structure 2 is connected to an end of the mounting portion 12, the inner water cut body 11, the end of the mounting portion 12 and the inner panel 100 form an opening 3, the corner structure 2 covers the opening 3 and is sealed with the inner panel 100.

[0033] Combination Figure 1 and Figure 3 As shown, a schematic diagram of the related structures at both ends of the inner water cut 1 is shown, and the corner structure 2 is not shown. It can be seen that a window is provided on the inner panel 100 of the door, and the mounting portion 12 is connected to the inner panel 100 (by means of snap connection, bonding, etc.). The inner water cut body 11 and the mounting portion 12 usually adopt an integrated structure, so that the inner water cut body 11 can contact the glass, and the inner panel 100 forms fillets 101 at the four corners of the window. For the inner water cut 1, its two ends are just located near the two fillets 101. Due to the process requirements of the inner panel 100, at this position, the inner panel 100, the mounting portion 12 and the inner water cut body 11 surround an opening 3. The dotted box in the figure roughly shows the range of the opening 3, but for different door structures of different models, the specific structure of the opening 3 here may be different. For example, in this embodiment, a reinforcing plate 200 is also installed on the inner panel 100, resulting in the opening 3 being divided into two parts by the reinforcing plate 200. During driving, wind may pass through these two parts of the opening 3 to generate wind noise. Combined with Figure 2 and Figure 4As shown, a schematic diagram of the relevant structure at both ends of the inner water cut 1 is shown, and an angle structure 2 is shown. The angle structure 2 is connected to the end of the mounting portion 12, which can cover the opening 3, and the angle structure 2 can be made of a material with sealing properties, and through sealing cooperation with the inner plate 100, the effect of sealing and covering the opening 3 is achieved.

[0034] Furthermore, the mounting portion 12 includes a first covering portion 121, the corner structure 2 includes a second covering portion 21 connected to the first covering portion 121, the first covering portion 121 and the second covering portion 21 are sealed with the edge of the inner panel 100, and the second covering portion 21 covers the opening 3.

[0035] Combination Figure 2 , Figure 4 as well as Figures 5 to 9 As shown, the first covering portion 121 of the mounting portion 12 and the second covering portion 21 of the corner structure 2 are connected to each other, so that the first covering portion 121 and the second covering portion 21 cover the edge of the inner panel 100 and seal with the edge of the inner panel 100, and the second covering portion 21 also covers the opening 3 at the same time, thereby ensuring the sealing at the opening 3. In addition, since the reinforcing plate 200 is installed on the inner panel 100, the second covering portion 21 can also seal with the edge of the reinforcing plate 200, thereby providing a better sealing effect.

[0036] In this way, the second covering portion 21 of the corner structure 2 is connected and fixed to the edge of the inner panel 100 through the first covering portion 121 of the mounting portion 12, and ensures the sealing of the edge of the inner panel 100, and also covers the opening 3 to prevent dust and other impurities from falling between the inner and outer panels of the door and affecting the lubrication structure therein, and to prevent air leakage at the opening 3 during driving to generate noise, thereby improving the overall NVH performance (Noise, Vibration, Harshness) of the vehicle.

[0037] Furthermore, the mounting portion 12 also includes a third covering portion 122 connected to the first covering portion 121, the corner structure 2 includes a fourth covering portion 22 connected to the second covering portion 21, the third covering portion 122 and the fourth covering portion 22 are connected to each other, and the third covering portion 122 and the fourth covering portion 22 are sealed with the panel surface of the inner panel 100.

[0038] Combination Figure 2 , Figure 4 as well as Figures 5 to 9As shown, the first covering portion 121 and the third covering portion 122 of the mounting portion 12 are integrally connected and form a certain angle, so that the first covering portion 121 is sealed to the edge of the inner panel 100, and the third covering portion 122 is sealed to the board surface of the inner panel 100. Similarly, the second covering portion 21 and the fourth covering portion 22 of the corner structure 2 are integrally connected and form a certain angle, so that the second covering portion 21 is sealed to the edge of the inner panel 100, and the fourth covering portion 22 is sealed to the board surface of the inner panel 100.

[0039] In this way, the edge and the board surface of the inner panel 100 are sealed by the first covering portion 121 and the third covering portion 122 of the mounting portion 12, and the second covering portion 21 and the fourth covering portion 22 of the corner structure 2, especially the opening 3 is covered by the second covering portion 21, and the second covering portion 21 is sealed and cooperated with the board surface of the inner panel 100 through the fourth covering portion 22, thereby further improving the sealing performance at the opening 3.

[0040] Furthermore, a rounded corner portion 221 is connected to the fourth covering portion 22 , and the rounded corner portion 221 is sealed and matched with the plate surface at the rounded corner 101 of the inner plate 100 .

[0041] Combination Figure 2 and Figure 4 As shown, the fourth covering portion 22 of the corner structure 2 is integrally connected with the rounded corner portion 221. The rounded corner portion 221 is in sheet shape as a whole, and the portion covering the inner panel 100 is similar to a circle, and its contour is a circular arc line, thereby corresponding to the plate surface shape at the rounded corner 101 on the inner panel 100, achieving a better sealing effect.

[0042] Furthermore, an edge of the second covering portion 21 close to the vehicle exterior is connected to an edge of the inner watertight body 11 close to the vehicle interior.

[0043] Combination Figure 2 , Figure 4 , Figure 8 and Fig. 9 As shown, the edge of the second covering portion 21 close to the outside of the vehicle (the positive side of the Y axis in the figure) and the edge of the inner water-cut body 11 close to the inside of the vehicle (the negative side of the Y axis in the figure) are connected by integral connection or bonding.

[0044] In this way, the sealing performance of the inner water cut 1 and the corner structure 2 for the opening 3 is improved, which prevents wind from entering the opening 3 during driving and causing wind noise, thereby improving the overall NVH performance of the vehicle.

[0045] Furthermore, one end of the second covering portion 21 away from the mounting portion 12 extends toward the glass groove 300 and is provided with a flange portion 211 , and the flange portion 211 is sealed and matched with the glass groove 300 .

[0046] Combination Figure 2 and Figure 4 As shown, the second covering portion 21 of the corner structure 2 covers the opening 3 and is sealed with the edge of the inner panel 100. The second covering portion 21 is connected to the mounting portion 12. The end of the second covering portion 21 extends toward the glass groove 300, and a flange portion 211 is provided at the end of the second covering portion 21, so that a sealing fit is achieved by the flange portion 211 fitting with the glass groove 300.

[0047] In this way, after the second covering part 21 covers the opening 3, the second covering part 21 is sealed with the edge of the inner panel 100, the rounded corner part 221 is sealed with the panel surface at the rounded corner 101 of the inner panel 100, and the fourth covering part 22 is sealed with the panel surface of the inner panel 100, the flanged part 211 is further sealed with the glass groove 300, so as to achieve better sealing effect on the opening 3 and improve the NVH performance of the whole vehicle.

[0048] Furthermore, an arc portion 23 is connected between the second covering portion 21 and the rounded corner portion 221 , and the arc portion 23 is sealed and matched with the edge of the rounded corner 101 of the inner plate 100 .

[0049] Combination Figure 2 and Figure 4 As shown, the arc portion 23 is an arc shape as a whole, corresponding to the shape of the rounded corner 101 of the inner panel 100. The arc portion 23 is located between the second covering portion 21 and the rounded corner portion 221, and is integrally connected to the second covering portion 21 and the rounded corner portion 221, so as to fit and seal with the edge of the rounded corner 101 of the inner panel 100.

[0050] In this way, the arc-shaped portion 23 improves the sealing performance at the edge of the fillet 101 of the inner panel 100, which is beneficial to improving the sealing effect of the opening 3 and enhancing the NVH performance of the entire vehicle.

[0051] Furthermore, the inner water-cut body 11, the mounting portion 12 and the corner structure 2 are integrally connected.

[0052] Combination Figure 2 , Figure 4 as well as Figures 5 to 9As shown, the inner water-cut body 11, the mounting portion 12 and the corner structure 2 are integrally connected. Specifically, PP-TD20 plastic particles and TPV particles are formed into the inner water-cut body 11 and the mounting portion 12 through an extrusion mold. The inner water-cut body 11 is usually subjected to velvet pasting and cutting processes, and then the inner water-cut 1 is placed in a corresponding mold and the corner structure 2 is formed by injection molding.

[0053] In this way, when the inner water cut 1 and the corner structure 2 are assembled on the vehicle door, a certain clamping limit is formed between the inner water cut 1 and the corner structure 2 and the inner panel 100, which reduces the assembly error and also improves the installation efficiency.

[0054] Optionally, a sponge block is provided at the opening 3, and the corner structure 2 is crimped to the sponge block (the sponge block is not shown in the figure, and the shape and size of the sponge block can be designed according to needs).

[0055] In this way, the sponge block can play a better sealing role on the opening 3, and the corner structure 2 can play a better sealing role on the periphery of the opening 3, and at the same time play a role in pressing and fixing the sponge block, achieving a better sealing effect and improving the overall NVH performance of the vehicle.

[0056] The sealing assembly of the present invention is mainly used in vehicle doors, and the mounting portion 12 is mounted on the inner panel 100 of the vehicle door, and the inner water-cut body 11 is in contact with the vehicle door glass. Corresponding to the opening 3 surrounded by the inner water-cut body 11, the end of the mounting portion 12 and the inner panel 100, the corner structure 2 is connected to the end of the mounting portion 12, so that it can cover the opening 3, and seal with the inner panel 100 to play a sealing role at the opening 3, avoid wind noise caused by wind passing through the opening 3 during driving, and avoid impurities such as dust from entering between the inner and outer panels of the vehicle door through the opening 3 to affect the lubrication structure therein, thereby improving the overall NVH performance of the vehicle. Compared with the solution of sticking sponge strips in traditional technology, the corner structure 2 in the present invention is more reliable, not easy to fall off, and has a better sealing effect.
