When the hinge is applied to electronic equipment, the rotation direction of the first body which is opened relative to the second body is set to be the first direction, correspondingly, when the first body drives the first shaft 100 to rotate along the first direction, the linkage assembly drives the second shaft 200 to rotate along the opposite direction of the first direction through the connection relation between the first connection surface and the second connection surface, so that the second body rotates along the opposite direction of the first direction, the actual opening angle of the first body and the actual opening angle of the second body are larger than the rotation angle of the first body, the two bodies of the electronic equipment are quickly opened, and the hinge is convenient for a user to use.
On the basis, in order to enable the two bodies of the electronic device to be quickly closed, the hinge is configured such that when the first shaft 100 rotates in the opposite direction of the first direction, the first connection surface of the second shaft 200 drives the second connection surface of the second shaft 200 to rotate through the linkage device, and the second shaft 200 rotates around its axis in the first direction. In this embodiment, when the first body is closed for the second body, the first body rotates, and the linkage assembly can drive the second connecting surface of the second shaft 200 to rotate under the action of the first shaft 100, so that the second body rotates in the opposite direction, the actual closing angle of the first body and the second body is larger than the rotating angle of the first body, quick closing can be realized, and the use by a user is facilitated.
Preferably, the first connecting surface is an end surface of the first shaft 100, and the second connecting surface is an end surface of the second shaft 200.

wherein the linkage assembly is used to simultaneously rotate the first shaft 100 and the second shaft 200 about their axes in opposite directions. In the hinge, the first shaft 100 and the second shaft 200 rotate around respective axes at the same time, namely, when the first body is driven to rotate, the second body rotates in the opposite direction at the same time under the action of the linkage assembly, the opposite rotation of the second body is not delayed, the second body stops immediately when a user rotates the first body to a proper angle, the time for the user to wait for the second body to rotate independently to stop is saved, and the user can use the electronic equipment conveniently.
Preferably, the linkage assembly is configured to rotate the second shaft 200 in the same angle about the respective axes in opposite directions simultaneously with the first shaft 100.

In this embodiment, the first connecting shaft 301 and the second connecting shaft 302 are respectively configured as crankshafts, and the two connecting shafts are connected by the first connecting rod 331 and the second connecting rod 332, so that when the first connecting rod 331 reaches a critical position, the second connecting shaft 302 moves under the action of the second connecting rod 332, and when the second connecting rod 332 reaches the critical position, the second connecting shaft 302 moves under the action of the first connecting rod 331, thereby ensuring that the two connecting rods move along the first preset track or the opposite direction of the first preset track respectively. Specifically, in this embodiment, the connection relationship between the third shaft pin, the fourth shaft pin and the connecting plate, the connection relationship between the crankshaft and the first shaft 100 or the second shaft 200, and the connection relationship between the crankshaft and the connecting rod may be as follows:

In the hinge provided by the above embodiment, the linkage assembly may further include a flexible connecting member 310, and both ends of the flexible connecting member 310 are respectively fixed to the end surface of the first shaft 100 and the end surface of the second shaft 200; when the first shaft 100 rotates around its own axis, the first shaft 100 transmits a torque force to the second shaft 200 through the flexible connecting member 310, and drives the second shaft 200 to rotate around its own axis. Specifically, the flexible connecting member 310 is curved to form an arc, and when the first shaft 100 rotates around its own axis, the flexible connecting member 310 is driven to twist along its own axis, so as to drive the second shaft 200 to rotate around its own axis in a direction opposite to that of the first shaft 100.
In this embodiment, the flexible connecting member 310 may be a flexible shaft made of a flexible material, or a flexible shaft made of a plurality of continuous wires, or a flexible shaft made of a plurality of connecting joints connected in sequence.
