[0020] From the above description, it can be seen that the beneficial effects of the present invention are: by setting a first hinge structure with a U-shaped cross-section to connect the first body 1 and the second body 2, there is a gap between the first body 1 and the second body 2 that can accommodate the third body 3, and setting a second hinge structure with a teardrop-shaped cross-section to connect the second body 2 and the third body 3, so that the gap between the second body 2 and the third body 3 after folding is reduced, so that the overall thickness of the folding screen mobile phone with three folds inwards is reduced when it is in the folded state.

[0021] Furthermore, the thickness of the third body 3 is smaller than the thickness of the first body 1 and the thickness of the second body 2 .

[0022] From the above description, it can be seen that setting the thickness of the third body 3 to be smaller than the thickness of the first body 1 and the thickness of the second body 2 facilitates better storage of the third body 3 between the first body 1 and the second body 2, which is beneficial to improving the compactness of the structure.

[0023] Furthermore, the first hinge structure includes a first shell 4, a first hinge plate 41, a second hinge plate 42, a first synchronous gear 43 and a second synchronous gear 44. The first hinge plate 41, the second hinge plate 42, the first synchronous gear 43 and the second synchronous gear 44 can be rotatably installed on the first shell 4 respectively.
