Abstract

The invention discloses a damping spring buffer device, which is characterized by comprising an installation supporting frame provided with a through hole and installation lugs, a spring, a piston and a rope, wherein the spring and the piston are arranged in the through hole, one end of the rope is connected with the piston, a stop bump used for limiting the piston to move is arranged at one end of the supporting frame, two ends of the spring are respectively connected with the piston and the other end of the installation supporting frame, and the other end of the rope penetrates through the spring and is located outside the through hole. According to the damping spring buffer device, through the arrangement of the damping spring, the opening speed of a storage box is uniform and controllable, and impact is not generated when the storage box is closed; thereby, articles inside the storage box are ensured to be prevented from vibrating, falling off, flying out, giving out abnormal sound or impacting passengers when the storage box is opened, and the normal service life of the storage box is prolonged.

Description

technical field [0001] The invention relates to auto parts, in particular to a damping spring buffer device. Background technique [0002] Some car glove boxes now, due to the lack of buffering and stabilizing devices, are affected by the gravity of themselves and the contents when they are opened, and will accelerate downward movement; vibration, shock, abnormal noise, items flying out, hitting The situation of the passengers will also affect the life of the glove box due to impact. Contents of the invention [0003] The object of the present invention is to provide a damping spring buffer device with simple structure, convenient installation, uniform and controllable speed when opening the storage box, and no impact when closing. [0004] The present invention is a damping spring buffer device, which is characterized in that it includes a mounting bracket provided with a through hole and mounting ears, a spring and a piston located in the through hole, and a rope connec...
