[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model specification, the meaning of "multiple" is two or more.
[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0030] Figure 1 A structural schematic diagram of a long slide rail for a car seat provided by an exemplary embodiment of the present invention is shown, wherein the long slide rail for a car seat includes a fixed lower rail 1 and a sliding upper rail 2 slidably connected to the fixed lower rail 1, and the long slide rail for a car seat also includes: an embedded track rubber strip 3 and an elastic rolling wheel mechanism 4, the embedded track rubber strip 3 is connected to the sliding upper rail 2 in a movable manner, and the part other than the part cooperating with the sliding upper rail 2 is embedded in the track opening 11 of the fixed lower rail 1; there are two elastic rolling wheel mechanisms 4, which are respectively installed at both ends of the sliding upper rail 2.
[0031] In this embodiment of the present application, the embedded track rubber strip 3 is movably connected to the sliding upper rail 2, and the portion not engaged with the sliding upper rail 2 is embedded in the track opening 11 of the fixed lower rail 1. This effectively seals the gap between the rails, preventing the ingress of dust and impurities, and improving the smoothness and stability of sliding. An elastic roller mechanism 4 is mounted at both ends of the sliding upper rail 2, providing uniform pressure and support to ensure that the embedded track rubber strip 3 remains embedded in the track opening 11 of the fixed lower rail 1 during the sliding process of the sliding upper rail 2.
[0032] For more details, see Figure 2 and Figure 3 The elastic roller mechanism 4 includes a flip cover 41 hinged to the end of the upper sliding rail 2, and a downward pressure roller 42 rotatably connected to the flip cover 41. The downward pressure roller 42 rolls in contact with the embedded track rubber strip 3. A compression spring 43 is installed at the hinged location of the flip cover 41 and the end of the upper sliding rail 2, which is used to press the flip cover 41 downward, ensuring that the downward pressure roller 42 always exerts downward pressure on the embedded track rubber strip 3. Specifically, the end of the upper sliding rail 2 has a hinged seat 21, through which the flip cover 41 is hinged to the end of the upper sliding rail 2, and the compression spring 43 is installed on the inner side of the hinged seat 21.
[0033] In the embodiment of the present application, the flip cover 41 is hinged to the end of the sliding upper rail 2, and a compression spring 43 is installed at the hinge. The function of the compression spring 43 is to press the flip cover 41 downward so that the downward pressure roller 42 installed thereon always exerts downward pressure on the embedded track rubber strip 3. This arrangement ensures stable contact and rolling between the downward pressure roller 42 and the embedded track rubber strip 3, which not only reduces friction and noise during sliding, but also improves the smoothness and reliability of the slide rail system. In addition, the design of the flip cover 41 allows it to be flipped up when necessary, which is convenient for maintenance and cleaning, while also protecting the downward pressure roller 42 and the embedded track rubber strip 3, extending the service life of the system. This ingenious structural design ensures that the long slide rail of the car seat can operate smoothly and stably under various working conditions.
[0034] It can be understood that the interior of the sliding upper rail 2 has multiple groups of guide rollers that play a guiding and supporting role for the embedded track rubber strip 3.
[0035] In this embodiment, the upper sliding rail 2 is equipped with multiple sets of guide rollers that guide and support the embedded track strip 3. Specifically, these multiple sets of guide rollers ensure smooth movement of the embedded track strip 3 within the upper sliding rail 2, reducing friction and wear and improving the smoothness and stability of sliding. This design not only enhances the overall performance of the slide rail system but also extends the service life of the embedded track strip 3 and the upper sliding rail 2, ensuring smooth and reliable sliding of the car seat under various operating conditions.
[0036] Further, see Figure 2 and Figure 3 The elastic rolling wheel mechanism 4 also includes a brush head 44, which is installed on the flip cover 41. The brush head 44 is located on the side of the lower pressure roller 42 away from the sliding upper rail 2, and the brush head 44 is in close contact with the embedded track rubber strip 3.
[0037] In the embodiment of the present application, the above arrangement serves to continuously remove dust and impurities from the surface of the embedded rail rubber strip 3 via the brush head 44, ensuring the cleanliness of the rubber strip surface, thereby reducing friction and wear during sliding and improving the smoothness and reliability of the long slide rail. The presence of the brush head 44 also prevents dust and impurities from entering the interior of the slide rail, thereby extending the service life of the entire long slide rail.
[0038] For further information, see Figure 1 and Figure 2 The elastic rolling wheel mechanism 4 also includes a front end cover plate 45, which covers the flip cover 41, and the front end cover plate 45 is located on the side of the brush head 44 away from the sliding upper rail 2; wherein, the front end cover plate 45 is inclined in the front and rear directions and the left and right directions, and is inclined in the front and rear directions toward the direction of the sliding upper rail 2, and is not limited in the left and right directions, and can achieve the function of guiding the discharge of foreign matter either left or right.
[0039] In the embodiment of the present application, the front end cover plate 45 simulates the structure of a bulldozer icebreaker, and can push away foreign objects during movement.
[0040] Next, the working principle of the long slide rail of the car seat involved in the embodiment of the present utility model is described.
[0041] When the sliding upper rail slides on the fixed lower rail, the fully covered embedded track rubber strip prevents foreign matter from invading the fixed lower rail; the flip cover, compression spring, and downward pressure roller are arranged in coordination to apply constant pressure to the embedded track rubber strip during movement, thereby promoting the embedded track rubber strip to be embedded in the track opening of the fixed lower rail; the front end cover of the elastic rolling wheel mechanism can simultaneously clean and remove larger foreign matter during operation, and the brush head of the elastic rolling wheel mechanism can simultaneously clean and remove smaller foreign matter during operation, thereby preventing foreign matter on the embedded track rubber strip from being drawn into the interior of the sliding upper rail, thereby fully ensuring the cleaning effect of the slide rail path.
[0042] In the embodiments disclosed in this utility model, the terms "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, "connected" can refer to a fixed connection, a detachable connection, or an integral connection; "connected" can refer to a direct connection or an indirect connection via an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the embodiments disclosed in this utility model based on specific circumstances.
[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
