A wire slot 408 is provided on the front face of the sealing curtain body 1 on one side of the wire hole 407. The sealing frame 407... A second magnet 404 is provided at the upper and lower center of the inner side wall of the sealing curtain body 1. A second magnetic groove 405 is provided at the upper and lower center of the side wall of the sealing curtain body 1. The two second magnets 404 are respectively matched with the two second magnetic grooves 405. A wire groove 406 is provided at the upper and lower center of the other side of the front inner wall and the rear inner wall of the sealing frame 401. A sealing cover 409 is provided at the lower center of the front face and the lower center of the rear face of the sealing curtain body 1. The two sealing covers 409 are respectively rotatably connected to the center of the front face and the center of the rear face of the wire groove 406. A protrusion 411 is provided at the center of the lower end face of the two sealing covers 409. A limiting block 410 is provided at the lower center of the front face and the lower center of the rear face of the sealing frame 401.

[0027] The sealing curtain body 1 is the main support part of the entire sealing curtain. It is connected to other components through the sleeve 5 and plays a role in positioning and assisting installation. The sealing frame 401 slides in the sliding groove 402 through the slider 403. The position of the sealing frame 401 can be adjusted according to the actual needs of sealing during the opening or closing of the car door, or the wiring layout and maintenance. The sealing frame 401 and the sealing curtain body are attracted and connected by the second magnet 404 and the second magnetic suction groove 405 to ensure that the sealing frame 401 can be reliably fixed on the sealing curtain body 1 after sliding adjustment, so as to achieve sealing of specific areas of the car door. The wire groove 406 is used to manage the relevant wires in the car. The sealing cover 409, through the cooperation of the protrusion 411 and the limiting block 410, can prevent external dust and debris from entering the wire groove 406 and also prevent the wiring from being accidentally pulled and damaged during the daily opening and closing of the car door.

[0028] The sealing curtain body 1 has protective structures 2 at the center of both the front and rear ends. Each protective structure 2 includes two rubber protective plates 201, which are respectively located at the center of the front and rear ends of the sealing curtain body 1. Pins 202 are located on the upper sides of the rear ends of the front rubber protective plates 201 and on the upper sides of the front ends of the rear rubber protective plates 201. Slots 203 are located on the upper sides of the sealing curtain body 1, both at the front and rear ends. The four pins 202 are mutually matched with the four slots 203. The rubber protective plates 201 are soft and elastic, providing cushioning when the door is impacted or squeezed, reducing the impact on the sealing curtain body 1 and related components inside the vehicle. The rubber protective plates 201 are installed on the sealing curtain body 1 through the cooperation of the pins 202 and slots 203, making installation and removal convenient and facilitating replacement when damaged.

[0029] A sealing structure 3 is fitted onto the outer wall of the sealing curtain body 1. The sealing structure 3 includes a rubber sealing strip 301, which is fitted onto the outer wall of the sealing curtain body 1. The rubber sealing strip 301 has a first magnetic groove 302 on both sides of the center of its upper end face. A sealing cover 303 is located at the center of the upper end face of the rubber sealing strip 301. A first magnet 304 is located on both sides of the center of the lower end face of the sealing cover 303. The two sealing covers 303 are respectively matched with the two first magnets 304. A sealing gasket 305 is located at the center of the lower end face of the sealing cover 303. The sealing gasket 305 is attached to the upper surface of the sealing curtain body 1. The rubber sealing strip 301 serves as the first line of defense for sealing. By closely adhering to the outer wall of the sealing curtain body 1, it prevents external dust, rainwater, etc. from entering the vehicle through the gap between the sealing curtain body 1 and the door. The sealing cover 303 is fixed to the rubber sealing strip 301 by the adsorption of the first magnet 304 and the first magnetic groove 302. The sealing gasket 305 is closely attached to the sealing curtain body 1, filling any possible tiny gaps and further enhancing the sealing performance, ensuring the airtightness and comfort of the vehicle interior.

[0030] The working principle of this utility model is as follows: the rubber sealing strip 301 is fitted onto the outer wall of the sealing curtain body 1. Utilizing the elasticity and flexibility of the rubber material itself, when the car door is closed and fits against the car body, the rubber sealing strip 301 can tightly fill the gap between the car door and the car body, playing a preliminary role in blocking dust, rainwater and external noise. The sealing cover 303 is magnetically fixed to the rubber sealing strip 301 by the first magnet 304 at the lower end and the first magnetic groove 302 on the upper end of the rubber sealing strip 301. This magnetic structure not only ensures the stability of the connection, but also facilitates the disassembly and installation of the sealing cover 303. The presence of the sealing gasket 305 further enhances the sealing effect. It fits against the upper end of the sealing curtain body 1, effectively preventing rainwater from leaking into the car from the upper end of the sealing curtain.

[0031] The sealing frame 401 is slidably connected to the sliding groove 402 via the slider 403, allowing the sealing frame 401 to move flexibly relative to the sealing curtain body 1, facilitating installation, disassembly, or position adjustment. After installation, the second magnet 404 on the inner wall of the sealing frame 401 attracts the second magnetic groove 405 at the corresponding position of the sealing curtain body 1, ensuring a tight fit between the sealing frame 401 and the sealing curtain body 1, preventing dust, rainwater, and noise from intruding from the side. The wire groove 406 is used to place wires or other wire harnesses. The sealing cover 409 opens or closes the wire groove 406 by rotation. When closed, the protrusion 411 on the lower end face of the sealing cover 409 cooperates with the limiting block 410 on the sealing frame 401 to prevent the sealing cover 409 from opening accidentally, ensuring the stable placement of items in the wire groove 406, preventing them from falling and affecting the seal, and improving the overall sealing performance of the side.

[0032] The rubber protective plate 201, located at the center of the front and rear faces of the sealing curtain body 1, serves as a buffer and protector. When the car door is subjected to external impact, friction, or impact force generated when opening and closing the car door, the rubber protective plate 201 is the first to come into contact with the external force. With the good elasticity and toughness of the rubber material, it absorbs and disperses the impact force and friction force, preventing the sealing curtain body 1 from being directly damaged by force, thereby extending the service life of the sealing curtain body 1 and better maintaining the stable operation of the overall function of the sealing curtain assembly.

[0033] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
