Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle parts and specifically relates to a waterproof and dustproof zipper structure for a long slide rail of a vehicle seat. Background Art

[0002] With the improvement of people's living standards and the continuous progress of science and technology, the automobile industry has developed by leaps and bounds, and people's requirements for automobile quality and comfort have also been continuously improved. As one of the important components of a car, a superior seat design can bring a comfortable riding experience to passengers. In the process of driving or riding a car, in order to adjust the body of the driver and passengers to a comfortable driving posture, the front and rear position of the car seat needs to be adjusted when the person is on the car seat, and the car seat slide rail is a component to realize the above function; specifically, the above-mentioned car seat slide rail device plays the role of changing the front and rear position of the seat and locking it, which can improve the space size in the front of the seat and effectively improve the comfort and convenience of the seat, and facilitate passengers to enter the vehicle. The existing vehicle seat slide rail usually includes an upper slide rail, a lower slide rail and a driving mechanism. The upper slide rail is connected to a slide seat or a slide frame fixed to the vehicle seat frame. The upper slide rail is wrapped in the lower slide rail and can slide relative to the lower slide rail. The lower slide rail is fixed on the vehicle body floor. The upper slide rail is driven by the driving mechanism to move forward and backward to drive the slide seat and the seat to move together. However, since the seat is installed on the slide rail, and the slide rail device is often directly fixed and exposed on the bottom plate of the vehicle body, such a structure not only has a poor visual appearance, but also makes the overall bottom plate of the vehicle body very unsightly. Some debris, dust and foreign matter will fall into the lower slide rail, thereby hindering the smooth operation of the seat along the slide rail. At the same time, some sewage and water can easily enter the lower slide rail, which can easily produce odor over time and affect cleanliness. Especially for some long slide rail devices, foreign matter is more likely to fall into the inner cavity of the lower slide rail, which makes the overall operation reliability of the slide rail device poor and affects the safety of use. Therefore, achieving the sealing of the slide rail device and playing a waterproof and dustproof role has become a goal that the automotive parts industry urgently needs to achieve.

[0003] There is also no shortage of technical solutions for realizing dustproof and waterproof structures for slide rail devices in Chinese patent literature; the utility model patent with announcement number CN217791727U introduces a zipper structure for seat slide rails to prevent foreign objects, including an upper rail and a lower rail, the upper rail and the lower rail are slidably matched, and zipper heads movably connected to the upper rail are respectively provided at both ends of the upper rail, and two groups of dustproof rubber covers are fixedly provided on the upper end of the lower rail, and the two groups of dustproof rubber covers are respectively arranged on both sides of the lower rail, and a sewn elastic cloth is provided between the dustproof rubber cover and the lower rail, one side of the sewn elastic cloth is fixedly connected to the dustproof rubber cover, and the other side is provided with a zipper rack, the two groups of zipper racks are respectively connected to the zipper head, and when the zipper head slides, the two groups of zipper racks engage or separate with each other. The utility model provides a zipper structure above the slide rail, which effectively prevents various foreign objects from entering the lower rail and causing the upper rail to be unable to slide normally, reduces daily cleaning work, and ensures the service life and performance of the slide rail; however, it adopts a fixing method in which the dustproof rubber cover is connected to the lower rail by clamping, and this connection method causes relative displacement or deformation of the dustproof rubber cover, and cannot ensure long-term sealing and dustproof effects, and the sewn elastic fabric is directly locked on the lower rail through the sheet metal, which makes assembly cumbersome and is not convenient for maintenance and replacement, resulting in high production costs.

[0004] The application document with publication number CN118024972A discloses a high-strength, fully enclosed dust-proof structure for automobile seat slides, which relates to the field of automobile seat slides, including a seat slide and a seat slider connector that slides along the seat slide, a slide groove for the seat slider connector to slide is provided in the seat slide, a mounting groove is provided on the side wall on one side of the slide groove, a rotating shaft is fixedly arranged in the mounting groove along the extension direction of the seat slide, a dust guard plate group is rotatably arranged on the rotating shaft along the extension direction of the seat slide, a shift plate is provided on the side of the seat slider connector close to the rotating shaft, the seat slider connector is used to drive the shift plate to flip and unfold the adjacent dust guard plate, and a rebound structure is provided between the dust guard plate group and the rotating shaft. Although the dust shield inside the dust shield group is horizontally set in a normal state and supported by a support seat, thereby improving the fully enclosed dust-proof effect of the seat slide rail, its overall structure is complex and the number of components is large. The dust shield group is composed of multiple dust shields that are buckled together. There is a risk of mutual interference and collision between each dust shield and the seat slide rail, which increases the safety risk of operation and cannot guarantee the reliability of operation. It will also cause poor transmission inside the slide rail and reduce the stability of operation.

[0005] In view of the above situation, it is necessary to design a connection device that can achieve efficient waterproof and dustproof effect inside the long slide rail structure of the vehicle seat and ensure the stability of use and the convenience of assembly. To this end, the applicant has made a useful design, and the technical solution to be introduced below is produced in this context. Utility Model Content
