Of course, in other embodiments, the second elastic member can also be silicone.

When the foldable mobile terminal 100 needs to be folded until the included angle between the main body 1 is 0 degrees, the first structural members 11 are gradually turned inward respectively, and the sliding bar 1322 is driven to rotate relative to the fixing member 131, wherein the engagement in the fixing member 131 The component 1321 drives the second structural member 12 to also turn inward, and the first structural member 11 and the second structural member 12 realize symmetrical inward turning, so that the folding angle of the main body 1 gradually becomes smaller, and the curvature of the bending area 2a of the flexible screen assembly 2 It also gradually becomes larger, and the bending area 2a is continuously attached to the inner surface 1313 of the fixing member 131, and the fixing member 131 is pushed out toward the direction away from the bending area 2a of the flexible screen assembly 2, so as to increase the outer surface 1314 of the main body 1 length, so that the first structural member 11 can be attached to the second structural member 12 to realize the folding of the foldable mobile terminal 100;

When the foldable mobile terminal 100 needs to be flattened until the included angle between the main bodies 1 is 180 degrees, gradually turn the first structural members 11 outward respectively, and drive the sliding bar 1322 to rotate relative to the fixing member 131, wherein the fixing member 131 The engaging component 1321 drives the second structural member 12 to also turn outward, and the first structural member 11 and the second structural member 12 realize symmetrical outward turning, so that the folding angle of the main body 1 gradually becomes larger, and the second end 1222b of the sliding rod 1322 can gradually The length of the folded outer surface 1b of the main body 1 is gradually reduced as it is close to the bottom of the first sliding cavity 111a and the second sliding cavity 121a. After the foldable mobile terminal 100 is unfolded, the folded outer surface 1b of the main body 1 is straight. surface without wrinkles.

The foldable mobile terminal 100 provided by the present invention defines the connecting component 132 as an engaging component 1321 and two slide bars 1322, wherein the engaging component 1321 includes a pair of driven gears 1321a and gears meshingly connected to the pair of driven gears 1321a respectively The shaft 1321b, the meshing component 1321 realizes the folding of the main body 1 through the meshing of graded gears, so that the thickness of the engaging component 1321 is thinner, so that the thickness of the foldable mobile terminal 100 can also be made thinner accordingly; at the same time, because the flexible screen component 2 The bending area 2a of the flexible screen assembly 2 is in contact with the fixing member 131, so that the bending area 2a of the flexible screen assembly 2 is supported by flat parts, and the pressing sensitivity of the bending area 2a of the flexible screen assembly 2 is improved, thereby providing a body 1 with a thinner thickness. 1.
