The first hinge 150 is used to hinge the second body 110, and does not mean that the first hinge 150 is directly connected to the second body 110, but mainly means a connection route.

Referring to fig. 2 and 4, for the second linkage mechanism 250, the second linkage mechanism 250 includes a second hinge 260 hinged to the first body 100 and a third hinge hinged to the second hinge 260, the third hinge is hinged to the second body 110, and the second hinge 260 is hinged to the first hinge 150, so that the hinge can be opened in the state of fig. 1, and can also rotate 180 ° relatively, so that the first body 100 and the second body 110 are folded or attached to each other.

In some embodiments of the present invention, the second linkage mechanism 250 may be arranged in a mirror image with the first linkage mechanism 130, that is, the second linkage mechanism 250 is slidably connected to the second body 110, the second linkage mechanism 250 is hinged to the first body 100, and meanwhile, the second linkage mechanism 250 is rotatably connected to the first linkage mechanism 130, so that the size calculation may be simplified and the design difficulty may be reduced.

In some embodiments of the present invention, the second body 110 is provided with a first shaft and a second shaft arranged side by side, the first shaft is connected to the first linkage 130, and the second shaft is connected to the second linkage 250, so that the linkage 120 and the second body 110 can be connected together.

In some embodiments of the present invention, the second body 110 is provided with a hidden cavity, so that when the first linkage 130 and the second linkage 250 of the linkage 120 rotate, parts of the first linkage 130 and the second linkage 250 can be accommodated in the hidden cavity, so that the linkage 120 is hidden and not exposed.

Referring to fig. 2, 4 and 5, the hinge further includes a buffer mechanism 160, the buffer mechanism 160 is disposed on the first body 100, the buffer mechanism 160 abuts against the slider 140 to buffer, the buffer mechanism 160 includes an abutting member 170 and a damper 180, and the abutting member 170 is disposed between the damper 180 and the slider 140.

In summary, in the embodiment, the buffering mechanism 160 is provided, the buffering mechanism 160 has the abutting member 170 and the damper 180, and the abutting member 170 abuts against the slider 140 to realize buffering, so that a protrusion does not need to be provided on the second body 110, the structure can be simplified, and the occupied space can be reduced.

Meanwhile, since there is no need to provide a protrusion on the second body 110, the second body 110 of the present embodiment has a neat and simple appearance and no foreign object sensation when in the open state.

In addition, since no protrusion is required to be disposed on the second body 110, the present embodiment can reduce the overall size of the hinge, reduce the material consumption, and reduce the weight and cost.

Moreover, since there is no need to provide a protrusion on the second body 110, the width of the linkage device 120 can be increased, and the strength of the linkage device 120 can be improved.

In addition, since the abutting member 170 abuts against the sliding member 140 to achieve buffering, a top block is not required to be disposed in this embodiment, and the buffering mechanism 160 can be hidden in the first body 100 to prevent the buffering mechanism 160 from being damaged.

Furthermore, since the abutting member 170 abuts against the sliding member 140 to achieve buffering, a top block is not required to be disposed in this embodiment, and further, the force can be improved without affecting the movement of the abutting member 170 and the expansion and contraction of the damper 180.
