Hinge damping mounting structure

A hinge damping mounting structure, comprising:

• a long arm (100), wherein a first rotating shaft (110) and a second rotating shaft (120) are provided at an end of the long arm (100);
• a first connecting arm (200), hinged to the first rotating shaft (110);
• a second connecting arm (300), hinged to the second rotating shaft (120);
• a pocket (400), hinged to the first connecting arm (200) and second connecting arm (300);
• a mobile rack (500), comprising a first direction and a second direction perpendicular to each other, wherein the mobile rack (500) is slidingly mounted between the long arm (100) and the second connecting arm (300), the mobile rack (500) is limited by the long arm (100) and the second connecting arm (300) to translate in the first direction, the mobile rack (500) is capable of reciprocate and translate along a length direction of the long arm (100) in the second direction, and when the second connecting arm (300) is rotated around the second rotating shaft (120), the mobile rack (500) is pulled by the second connecting arm (300) to translate in the second direction toward the first connecting arm (200);
• an oil cylinder (600), mounted on the mobile rack (500) along the second direction, wherein the oil cylinder (600) comprises a telescopic shaft (610) and a cylinder shell (620), the telescopic shaft (610) is connected to the mobile rack (500) in a direction away from the first connecting arm (200), and an end of the cylinder shell (620) is supported by the first rotating shaft (110);
• a spring (130), sleeved on the first rotating shaft (110), wherein one leg of the spring (130) is abutted against the long arm (100), the other leg of the spring (130) is abutted against the second connecting arm (300), and the end of the cylinder shell (620) of the oil cylinder (600) is abutted against a side wall of the spring (130);
• wherein a sliding chute (520) is provided on the mobile rack (500) along the second direction;
• a support block (630) is located on the cylinder shell (620) of the oil cylinder (600), and the support block (630) is passed through the sliding chute (520) and abutted against the second rotating shaft (120);
• when the mobile rack (500) is translated, the support block (630) is slid relative to the sliding chute (520), and a travel distance of the mobile rack (500) is limited by an opening length of the sliding chute (520).
