Claims14
An optical module, comprising:
- an imaging lens group comprising at least a first lens having a beveled lens;
- a first bracket, with the first lens positioned therein;
- a lens barrel, with the first bracket movably positioned therein, an outer wall of the lens barrel being provided with an arc-shaped groove;
- an arc-shaped rack positioned in the arc-shaped groove, an arc length L1 of the arc-shaped rack being less than an arc length L2 of the arc-shaped groove;
- a lead screw gear comprising a lead screw and a gear provided at one end of the lead screw, the lead screw being in a transmission connection with the first bracket, the gear being engaged in a meshing transmission with the arc-shaped rack;
- and
- a driving member engaged in a meshing transmission with the arc-shaped rack and configured for driving the arc-shaped rack to rotate to actuate the lead screw gear to rotate, the lead screw gear being configured for driving the first bracket, thereby actuating the first lens to move along an axial direction of the lens barrel, so that the first lens is configured to match a diopter of a target object.
