  • Publication number: 20250127298
    Abstract: Disclosed in the present disclosure is a damping and rebounding sliding rail, including an outer rail, an inner rail slidably arranged within the outer rail, a damping device arranged at an end of the outer rail, and a rebound device, it is capable of causing the inner rail to slide with damping and synchronously compressing the rebound device when the inner rail is pushed to slide relative to the outer rail until the inner rail is close to the damping device, under the action of the damping device; then the inner rail is pushed again in the same direction, and the rebound device releases elastic force and drives the inner rail to slide in an opposite direction to achieve pop-up.
