[0045] In this embodiment, the synchronization mechanism 1b also includes a first fixed seat 1b1 and a second fixed seat 1b8 which are installed in the middle part of the inner side of the middle shrimp shell member 11 and are symmetrically arranged. The inner side of the first fixed seat 1b1 is provided with two first left lifting arms 1b2 and first right lifting arms 1b3 which have toothed structures and are meshed with each other, and the meshing ends of the first left lifting arm 1b2 and the first right lifting arm 1b3 are rotatably connected with the gear seat 1b6 through two positioning shafts 1b5. The two sides of the gear seat 1b6 are meshedly connected with a left rotating arm 1b9 and a right rotating arm 1b10 which cooperate with the first left lifting arm 1b2 and the first right lifting arm 1b3 to realize the smooth and synchronous rotation of the shrimp shell member. The left rotating arm 1b9 and the right rotating arm 1b10 form two corresponding rotating ends and are rotatably connected with the left connecting rod 1b13 and the right connecting rod 1b14 respectively, and both sides of the left rotating arm 1b9 and the right rotating arm 1b10 are provided with corresponding positioning shafts.

[0048] In addition, the lifting arm and the rotating arm, under the action of the gear meshing, cooperate with the torque generated by the torque plate 1b7, so that the hinge and the mobile terminal can be folded and stopped at the same time, and provide a good mechanical feedback during the rotation process.

[0049] In this embodiment, the locking mechanism 1c includes two sliding plates 1c1 which are rotatably connected to the left connecting rod 1b13 and the right connecting rod 1b14 respectively.

[0050] Specifically, in the process of the hinge from opening to closing: the left rotating arm 1b9 and the right rotating arm 1b10 rotate and close, and at the same time drive the sliding plate 1c1 to move toward one end of the corresponding sliding seat 1c3 under the cooperation of the guide bar 1c2 and the guide groove 1c4; the roller 1c8 on the spring seat 1c6 slides out of the slope lock, compresses the spring 1c7 by climbing up the slope at the beginning, and then rolls down the slope with the force provided by the spring 1c7, so as to quickly realize the closing of the hinge;

[0051] In the process of the hinge from closing to opening: the left rotating arm 1b9 and the right rotating arm 1b10 rotate and expand, and at the same time drive the sliding plate 1c1 to the middle of the corresponding sliding seat 1c3 under the cooperation of the guide bar 1c2 and the guide groove 1c4; the roller 1c8 on the spring seat 1c6 compresses the spring 1c7 by climbing up the slope at the beginning, and then goes downhill with the force provided by the spring 1c7 to open downhill, and finally makes the roller 1c8 slide into the sloped locking mouth, so as to achieve the locking of the hinge when it is fully expanded at 180°.

[0052] In this embodiment, the slide mechanism 1d includes a slider 1d1 installed at the end of the left fixed shell 21 and the right fixed shell 31, the slider 1d1 is slidably connected to a slide rail 1d2, the slide rail 1d2 is installed on the back of the left fixed shell 21 and the right fixed shell 31 corresponding to the back, and the two back cover rotating plates are rotatably connected by hinges.

[0053] Specifically, when the hinge is opened and closed, the rotating left fixed shell 21 and the right fixed shell 31 make the rear cover rotating plate move to both sides of the shell under the cooperation of the slider 1d1 and the slide rail 1d2, leaving space for the rotating shaft to bend.

[0054] When the hinge is in the process of closing and opening, the left fixed shell 21 and the right fixed shell 31 rotate in the same manner, so that the rear cover rotating plate moves toward the middle of the shell under the cooperation of the slider 1d1 and the slide rail 1d2, thereby supporting the hinge space.

[0055] Furthermore, one end of the first left lifting arm 1b2 and one end of the second left lifting arm 1b11 are connected to the corresponding first hinge lifting sliding groove 1a23 for guiding rotation through a bearing seat connected to the rotation of a pin, and one end of the first right lifting arm 1b3 and one end of the second right lifting arm 1b12 are connected to the corresponding second hinge lifting sliding groove 1a33 for guiding rotation through a bearing seat connected to the rotation of a pin, thereby ensuring the synchronous rotation of the shrimp shell parts by utilizing the cooperation between the lifting arm and the hinge lifting sliding groove under the action of the synchronization mechanism 1b.
