This requires a higher performance match for the moving load functions of the slide. The telescopic sliding rail can generate enough stroke capacity, and the sliding rail is particularly suitable for being applied to the storage space of the automobile. Due to the particularity of the environment inside the automobile, the automobile often has inertia force in the automobile during running, so that the sliding rail is required to have self-locking capacity, or has a certain damping effect in the whole process to resist the natural inertia force generated by the environment inside the automobile. Otherwise, the slide rail cannot be stabilized at a position under the application environment of normal running of the vehicle under the action of inertia force, and articles borne on the slide rail can randomly move in the sliding direction, so that the whole function is disabled. Not only influences the use feeling of the client, but also generates some potential safety hazards.

In order to achieve the effect of locking or damping the sliding rail in the sliding process, the damping sliding rail on the market at present has the following structure: the chinese utility model patent with the publication number "CN 214564821U" and the name "a stable type automobile interior damping slide rail" shows that its structure includes: the inner rail is provided with an elastic damper which acts on the inner wall of the outer rail and generates damping for the inner rail. In order to ensure the uniform stress of the inner rail, the elastic damper is usually arranged in the middle of the inner rail, and two ends of the outer rail form a closed structure through bending, so that the inner rail can only slide in the outer rail, the sliding stroke of the inner rail is very short, and the requirement of the market on a long-stroke telescopic sliding rail cannot be met.
