The second pin 80 passes through the fourth circular hole 205 and the eighth circular hole 324, so that the third end of the second connecting member 320 is rotatably connected to the fourth position of the one end of the second fixing member 20.

Pressing the damping member 410 into the accommodating cavity 401 of the slider 400, and abutting the bottom of the housing 412 against the bottom of the accommodating cavity 401; the slider 400 is then placed in the inner groove 203, such that one end surface of the cap 414 of the damper 410 is supported by the first elastic member 310, and the two straight legs 312 of the first elastic member 310 abut against the outer peripheral surfaces of the first protruding columns 325 on the fifth side wall 322 and the sixth side wall 323, respectively.

The closing action of the hinge is shown in conjunction with fig. 1, 3, 12 and 13:

in this embodiment, when the first fixing element 10 rotates around one end of the first connecting element 300 to the closing direction, and the predetermined angle is smaller than 30 °, the first fixing element 10 drives the second end of the second connecting element 320 to rotate around the third end of the second connecting element 320 along the first direction, the second end of the second connecting element 320 rotates around the third end of the second connecting element 320 along the second direction, and at this time, the second protruding pillar 326 is not abutted to the sliding seat 400.

When the first fixing element 10 rotates around one end of the first connecting element 300 in the closing direction and the preset angle is about 30 °, the torque of the first elastic element 310 drives the second end of the second connecting element 320 to rotate around the third end of the second connecting element 320 in the first direction through the first protruding pillar 325, and the second end of the second connecting element 320 rotates around the third end of the second connecting element 320 in the second direction, so that the second protruding pillar 326 abuts against the second protruding body 404 of the sliding seat 400.

When the hinge continues to rotate in the closing direction, the second protrusion 326 abuts against the second protrusion 404 of the slider 400, and pushes the slider 400 to slide in the inner groove 203 (see fig. 5) toward one end of the second fixing member 20, while supporting one end surface of the cap 414 abutting against the first elastic member 310.

The sliding of the sliding base 400 causes the spring 413 (see fig. 10) to be compressed, the spring 413 generates an elastic force due to the compression, and the elastic force is transmitted to the sliding base 400 through the bottom surface of the housing 412, so that the sliding base 400 receives the buffer resistance exerted by the spring 413 to slow down the sliding speed of the sliding base 400; meanwhile, the damping resistance for reducing the sliding speed of the slider 400 reduces the rotation speed of the first fixing member 10 through the first connecting member 300, the second connecting member 320, and the first elastic member 310.

In the present embodiment, when the first fixing element 10 rotates around one end of the first connecting element 300 to the opening direction and the preset angle is about 30 °, the second end of the second connecting element 320 rotates around the third end of the second connecting element 320 to the third direction, the second end of the second connecting element 320 rotates around the third end of the second connecting element 320 to the fourth direction, the second protrusion 326 is disengaged from the second protrusion 404 of the sliding seat 400, the spring 413 extends under the action of elastic force and ejects the housing 412, and pushes the sliding seat 400 to slide in the inner groove 203 toward the other end of the second fixing element 20. When the first fixing member 10 is completely opened, the hinge returns to the state before the closing operation.
