Large-depth-of-field variable-viewing-angle three-dimensional display module and augmented reality glasses thereof

The invention belongs to the field of three-dimensional augmented reality display, and relates to a large-depth-of-field variable-viewing-angle three-dimensional display module and augmented reality glasses thereof. The front surface of a shell of the large-depth-of-field variable-viewing-angle three-dimensional display module is made of a transparent plastic material, and the shell is provided with three open grooves, namely an electromagnetic vibration contact extending open groove, a lens frame open groove and a semi-transparent and semi-reflective mirror mounting open groove. And the two sides of the electromagnetic vibration contact extending open groove and the lens frame open groove are arc-shaped, so that an electromagnetic vibration contact and a lens frame can be allowed to rotate within a certain range. And the semi-transparent and semi-reflective mirror mounting open groove is circular. The shell has leakproofness, that is, after a wearer wears the device, external light isonly allowed to pass thr
