[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] like Figures 1-4 As shown, this embodiment provides a door sealing curtain for sealing an opening on the inner door panel 100. The door sealing curtain includes a curtain body 1, a sealing film 2, and a magnet 3. The curtain body 1 is disposed on the side of the inner door panel 100 facing the outer door panel, i.e., between the inner door panel 100 and the outer door panel. A reinforcing plate 200 is also disposed between the inner door panel 100 and the outer door panel, and the curtain body 1 is mounted on the reinforcing plate 200 between the inner door panel 100 and the outer door panel. The sealing film 2 is integrally formed with the curtain body 1. After passing through the opening of the inner door panel 100, the sealing film 2 is attached to the side of the inner door panel 100 away from the outer door panel, i.e., the sealing film 2 is attached to the side of the inner door panel 100 facing the driver's cab. The sealing film 2 has an annular strip structure and is continuously disposed along the circumference of the opening of the inner door panel 100. Magnet 3 is bonded to the side of the sealing film 2 away from the curtain body 1, and magnet 3 is used to attract it onto the inner door panel 100. By setting the sealing film 2 on the curtain body 1, the sealing film 2 passes through the opening of the inner door panel 100 and adheres to the side of the inner door panel 100 away from the outer door panel. Magnet 3 is bonded to the side of the sealing film 2 away from the curtain body 1, and the magnet 3 attracts it to the inner door panel 100, thus fixing the sealing film 2 and achieving a sealing function. When the door sealing curtain needs to be removed for maintenance or replacement of internal door components, magnet 3 can be removed from the inner door panel 100 to remove the door sealing curtain. After maintenance or replacement, the door sealing curtain can be reassembled, allowing for repeated disassembly and reuse of the door sealing curtain, reducing maintenance and replacement costs.

[0035] Furthermore, a buckle 11 is installed on the curtain body 1, and a hanging hole 210 is provided on the reinforcing plate 200. The buckle 11 is engaged in the hanging hole 210. The buckle 11 has an I-shaped structure and is fixedly connected to the curtain body 1. The engagement of the buckle 11 with the hanging hole 210 on the reinforcing plate 200 achieves the limitation of the curtain body 1. At the same time, the sealing film 2 is adhered to the magnet 3, and the magnet 3 is attracted to the inner panel 100 of the door. Thus, the limitation of the buckle 11, the sealing film 2, and the magnet 3 prevents the curtain body 1 from moving or swinging and generating noise during vehicle operation. Please refer to... Figure 4As shown, the hanging hole 210 is a key-shaped hole that is larger at the top and smaller at the bottom. The upper end is large enough for the buckle 11 to pass through, while the lower end is smaller than the diameter of both ends of the buckle 11. Thus, the buckle 11 slides down to the lower end after passing through the hanging hole 210 from the top, preventing it from coming off. Correspondingly, an observation hole 110 is also provided on the inner door panel 100, through which it is possible to visually observe whether the buckle 11 is installed correctly.

[0036] Optionally, a sealing sleeve 12 is also provided on the curtain body 1. The sealing sleeve 12 is used for the wire harness to pass through and to seal the wire harness. The material of the sealing sleeve 12 can be the same as or a different material as the curtain body 1. The sealing sleeve 12 is connected to the curtain body 1 by heat fusion. In this embodiment, the sealing sleeve 12 is preferably made of the same material as the curtain body 1. Furthermore, the sealing sleeve 12 achieves sealing by abutting against the sleeve or sheath of the wire harness.

[0037] Specifically, please refer to Figure 3 As shown, the sealing film 2 is adhered to the side of the magnet 3 away from the inner door panel 100, so that the magnet 3 and the inner door panel 100 are directly attracted, ensuring a tight fit between them. This also effectively avoids the sealing film 2 being continuously squeezed by the attraction force between the magnet 3 and the inner door panel 100, which would reduce its fatigue life. The magnet 3 is preferably strip-shaped and continuously arranged circumferentially along the side of the sealing film 2 away from the curtain body 1. Setting the magnet 3 as a strip and continuously arranged circumferentially along the side of the sealing film 2 away from the curtain body 1 can reduce the volume of the magnet 3 while ensuring the relevant functions, which is beneficial for weight reduction. In this embodiment, the width of the magnet 3 is 8mm-12mm, for example, it can be 8mm, 9mm, 10mm, 11mm or 12mm. In this embodiment, the width of the magnet 3 is preferably 10mm. In this embodiment, the height of the magnet 3 is 5mm-8mm, for example, it can be 5mm, 6mm, 7mm or 8mm. In this embodiment, the height of the magnet 3 is preferably 6mm.

[0038] Furthermore, in this embodiment, the curtain body 1 and the sealing film 2 are made of the same material, so that the materials at the joint between the curtain body 1 and the sealing film 2 are fused more fully, ensuring the mechanical properties and service life at the joint. In this embodiment, the curtain body 1 is made of PE foam, and the sealing film 2 is heat-fused to the curtain body 1, so that the joint between the sealing film 2 and the curtain body 1 has good sealing performance.

[0039] Specifically, in this embodiment, the thickness ratio of the curtain body 1 to the sealing film 2 is 5-20, thus giving the curtain body 1 a certain thickness, thereby improving its structural rigidity, making it less prone to deformation, and ensuring that the curtain body 1 has a relatively stable state after installation. In this embodiment, the thickness of the curtain body 1 is 2mm-6mm, for example, it can be 2mm, 3mm, 4mm, 5mm, or 6mm. In this embodiment, the thickness of the curtain body 1 is preferably 4mm. The thickness of the sealing film 2 is 0.1mm-1mm, for example, it can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, or 1mm. In this embodiment, the thickness of the sealing film 2 is preferably 0.8mm, that is, the thickness ratio of the curtain body 1 to the sealing film 2 in this embodiment is 5.

[0040] This embodiment provides a method for assembling a car door sealing curtain, used for assembling the car door sealing curtain in this embodiment. The assembly method for the car door sealing curtain includes:

[0041] The curved curtain body 1 is made to undergo elastic deformation;

[0042] The curved curtain body 1 is passed through the opening in the inner panel 100 of the door and hung on the reinforcing plate 200.

[0043] Unfold the sealing film 2 and attach the magnet 3 to the side of the sealing film 2 facing the inner door panel 100 on the side away from the curtain body 1.

[0044] Magnet 3 is attached to the inner door panel 100.

[0045] Before assembling the door sealing curtain, the clips 11 can be installed onto the curtain body 1 in the sub-assembly area. Simultaneously, the magnet 3 is attached to the side of the sealing film 2 facing the inner door panel 100, away from the curtain body 1. This shortens the assembly time on the final assembly line and improves production cycle time. When assembling the door sealing curtain, determine its orientation so that the sealing film 2 faces the driver's cab. Bend the curtain body 1 to induce elastic deformation. Pass the bent curtain body 1 through the opening in the inner door panel 100 and insert it into the gap between the inner door panel 100 and the outer door panel. Remove the external force on the curtain body 1 to allow it to return to its original shape. Move the curtain body 1 and observe it through the observation hole 110 on the inner door panel 100. When the clips 11 are near the mounting hole, fine-tune the curtain body 1 so that the clips 11 pass through the upper end of the hanging hole 210. Move the curtain body 1 downwards so that the clips 11 are engaged in place within the hanging hole 210. Then, unfold the sealing film 2 and attach the magnet 3 to the inner door panel 100 to complete the assembly of the door sealing curtain.

[0046] When the door sealing curtain needs to be removed for repair or replacement, first remove the magnet 3 from the inner door panel 100. Then, move the curtain body 1 upwards to disengage the clip 11 from the lower end of the hanging hole 210. Next, manipulate the curtain body 1 to completely disengage the clip 11 from the hanging hole 210. Finally, bend the curtain body 1 and remove it from the opening in the inner door panel 100. After the repair or replacement work is completed, repeat the above steps to reinstall the door sealing curtain, enabling its reuse.

[0047] This embodiment provides a vehicle, including the door sealing curtain of this embodiment or the assembly method of the door sealing curtain of this embodiment.
