HINGE MODULE AND FOLDABLE ELECTRONIC DEVICE INCLUDING SUCH MODULE Russian patent published in 2022 - IPC H04M1/02 G06F1/16 F16C11/04 

FIELD: portable electronic devices structural elements.

SUBSTANCE: invention relates to the field of structural elements of portable electronic user devices such as folding devices, namely devices containing a folding display. To achieve the effect, the hinge module includes a fixed structure including a central fragment, a guide fragment having an edge facing the edge of the central fragment, and a supporting fragment configured to connect the central fragment and the guide fragment. In this case, the inner space is formed between the central fragment and the guide fragment, a connecting shaft extending into the inner space through the central fragment and including a gear wheel formed on the outer circular surface of the connecting shaft, and a rotary structure located in the inner space. The rotary structure includes a circular arc-shaped gear having a plurality of gear teeth arranged in a circular arc that engages with the gear. In this case, the rotary structure rotates around an imaginary axis of rotation passing through the center of the circular arc of the gear in the form of an arc of a circle.

EFFECT: reducing the number of components of the device, which allows for a simplified assembly process and a reduction in the failure rate, while the rotary structure and the fixed structure can be fixed in the axial direction without the help of a separate elastic element, even in the event of an external shock, such as from a fall.
