At present, there are many mature folding electronic equipment on the market, and the hinge structure is an indispensable and crucial part in the folding electronic equipment.

[0003] However, the hinge structure occupies a relatively large space due to its role in folding the electronic equipment, and the hinge width (herein, referring to the width of the hinge structure in the unfolded state) affects the space of the folding electronic equipment in the unfolded state.

[0004] In the prior art, the swing arm in the hinge structure is usually connected with the frame support through a latch. When the width of the swing arm is shortened, the rotation angle of the swing arm is increased, which reduces the gap between the swing arm and the screen. In the process of repeated folding, interference occurs between the swing arm and the screen, which affects the service life of the screen assembly and further affects the user's experience. SUMMARY
