By having only one axle supporting box 1152, the effect of folding and spreading the housing 11 can be achieved, while ensuring that the weight of the mobile terminal 10 is increased less, which is convenient for the user to carry. In other embodiments, two shaft supporting boxes 1152 may be disposed at two opposite ends of the folding element 115, and each shaft supporting box 1152 is disposed at one end of the central line, so that the folding element 115 can rotate more precisely while rotating around the shaft supporting box 1152 as a central point, thereby preventing the first supporting frame 113 and the second supporting frame 114 from being displaced relative to the display 12.

In this embodiment, the folding assembly 1151 includes a main spine 11511, a spindle guide 11512, a spindle 11513, a first return spring 11514, and a second return spring 11515. The main ridge 11511 is rotatably coupled to the shaft support box 1152, the spindle guide block 11512 is coupled to the rotation spindle 11513 and the first support frame 113 or the second support frame 114, the first return spring 11514 is coupled between the spindle guide block 11512 and the rotation spindle 1151, and the second return spring 11515 is coupled between the first support frame 113 or the second support frame 114 and the main ridge 11511.

The main ridge 11511 is provided at the top thereof with a rotation column which is received in the receiving cavity of the shaft support box 1152, so that the main ridge 11511 can be rotated about the shaft support box 1152 as a central point. In this embodiment, since only one shaft support box 1152 is provided, the above-described rotation column is provided only at one end of the main ridge 11511. The main ridge 11511 is further provided with a step at a side adjacent to the first support frame 113 or the second support frame 114 to match the shape of the spindle guide block 11512, so that the spindle guide block 11512 is erected on the main ridge 11511.

Further, since the two main ridges 11511 of the folding member 1151 are rotated relative to each other, the adjacent ends of the two main ridges 11511 are rounded such that the two main ridges 11511 do not collide when rotated, and the two main ridges 11511 are rotated to be in a parallel position, and when the mobile terminal 10 is in the folded state, the sum of the diameters of the two circular arcs of the two main ridges 11511 plus the distance between the two main ridges 11511 is within the width of the folded region 11 d.

A boss 11511a is further provided on the top of the main ridge 11511 to support the movement of the spindle guide 11512. In this embodiment, the boss 11511a includes two portions, a first portion having a rectangular parallelepiped shape and a second portion having a semi-cylindrical shape, which is designed to match the shape of the cam 11512a in the spindle guide 11512. In other embodiments, other shapes for cam 11512a may be designed, and thus other corresponding mating bosses 11511a may be designed, directly in the shape of a cuboid, square, or cylinder.

In which a cavity is formed in the middle of the rotation shaft guide block 11512, the first return spring 11514 is disposed in the cavity, and the rotation shaft guide block 11512 is correspondingly formed with a stepped shape so that the rotation shaft guide block 11512 is partially covered on the rotation main shaft 11513. Further, in order to reduce the weight of the hinge guide block 11512 and thus the entire hinge mechanism 115, i.e., the mobile terminal 10, the cavity formed by the hinge guide block 11512 communicates with the outside. A connection post (not shown) is provided on each of the spindle guide 11512 and the spindle 11513 such that the first return spring 11514 is hooked between the two connection posts and the first return spring 11514 is connected between the spindle guide 11512 and the spindle 1151.

Further, the spindle guide block 11512 is further provided with a coupling hole 11512b below the cavity so that the spindle guide block 11512 is detachably coupled to the first support frame 113 or the second support frame 114 by a bolt. Specifically, each spindle guide block 11512 in this embodiment is provided with two connection holes 11512b, and a line connecting the two connection holes 11512 is perpendicular to the longitudinal axis of the main spine 11511.

Further, a cam 11512a is further provided at an end of each spindle guide 11512 adjacent to the spindle support box 1152, an upper surface of the cam 11512a abuts against the spindle 11513, a side surface of the cam 11512a abuts against the spindle support box 1152, and a lower surface of the cam 11512a abuts against a projection 11511a on the top of the main ridge 11511. Because the display screen 12 may deviate up and down during the bending and unfolding processes, if the display screen 12 is stuck to the first supporting frame 113 and the second supporting frame 114, the display screen 12 may be layered due to transverse shear stress during the bending and unfolding processes, and in order to ensure that the display screen 12 is stationary with respect to the first supporting frame 113 and the second supporting frame 114 during the bending process, the cam 11512a is designed according to the deviation of the display screen 12, so as to ensure that the display screen 12 is stationary with respect to the first supporting frame 113 and the second supporting frame 114 during the bending process.

The pivot shaft 11513 includes three portions, a first portion received in a cavity formed in the middle of the pivot guide 11512, a second portion having a lower surface that abuts an upper surface of the cam 11512a of the pivot guide 11512, and a third portion having a pivot post formed therebelow for pivotal connection to a pair of intermeshing drive gears 11521 disposed in the pivot support housing 1152.

Each rotating main shaft 11513 is rotatably connected to drive gear 11521 by the rotational connection of the rotating posts to intermeshed drive gears 11521. By designing the two intermeshing drive gears 11521 to give the rotating spindle 11513 a rotational urging force, the spindle guide 11512 is facilitated to move since the rotating spindle 11513 serves to position the spindle guide 11512.

In addition, a washer 11516 is provided on the top of the shaft supporting box 1152, and a washer 11516 is covered above the above-mentioned pair of driving gears 11521 engaged with each other, and the washer 11516 contacts with the third portion of the rotating main shaft 11513 to reduce the frictional resistance during the rotation of the rotating main shaft 11513.

Further, the main ridge 11511 is provided with a U-shaped hole 11511b, and in this embodiment, the U-shaped hole 11511b is provided below the second return spring 11515. The hinge mechanism 115 further includes a positioning pin 1153, and the positioning pin 1153 is connected to the first support frame 113 or the second support frame 114 through the U-shaped hole 11511 b. By designing the U-shaped aperture 11511b such that the main spine 11511 is able to move within the U-shaped aperture 11511b by the positioning action of the positioning pin 1153 during rotation of the support housing 1152 relative to the shaft, a guiding rotational action is provided to the main spine 11511 to avoid skewing.

When the mobile terminal 10 is used, the two main ridges 11511 rotate relative to the supporting box 1152 under the action of an external force, when the housing 11 and the display 12 are folded inwards, the two second return springs 11515 are compressed to have an elastic force of restoring to the original state, and the two first return springs 11514 are stretched to have a tensile force of restoring to the original state, so that the elastic force of the two second return springs 11515 and the tensile force of the two first return springs 11514 are balanced against each other, and the housing 11 and the display 12 can be kept in the folded-inwards state. When the housing 11 and the display screen 12 are maintained in a flat state, both the two second return springs 11515 and both the two first return springs 11514 handle a natural state.

The above-described hinge mechanism 115 is used as follows: when the mobile terminal 10 needs to be folded, the opposite ends of the mobile terminal 10 in the direction of the front surface 11a are pressed by the hand of a human body to be folded inwards, at this time, the main ridge 11511 rotates around the shaft supporting box 1152 as a central point, the U-shaped hole 11511b on the main ridge 11511 moves along the positioning pin 1153, the two second return springs 11515 are compressed, the rotating main shaft 11513 rotates around the shaft supporting box 1152 as a central point, and at the same time, the rotating column on the rotating main shaft 11513 pushes the driving gear 11521 to rotate, the two first return springs 11514 are stretched, the two second return springs 11515 are compressed to have an elastic force for recovering, the two first return springs 11514 are stretched to have a tensile force for recovering, and the elastic force and the tensile force are in a balanced state, so that the mobile terminal 20 can be folded inwards in different forms and in a folded state like as a wallet. When the mobile terminal 10 needs to be restored, the above components may move in opposite directions.
