Abstract
A motor structure with a built-in lens includes a lens mount (10), a motor (30) received in the lens mount, and a lens unit (50) received in the lens mount. The lens unit is drove by the motor to telescopically move along an axial thereof when a rotor (34) of the motor is rotated. A guiding member (70) arranged on an end of the motor for preventing an axial movement of the motor. The guiding member includes at least a leg (78) extending along an axial direction therefrom for guiding the axial movement of the lens unit.
Claims15
A motor structure with built-in lens comprising:
- a lens mount;
- a motor received in the lens mount;
- a lens unit received in the lens mount and driven by the motor to telescopically move along an axial thereof;
- and
- a guiding member arranged on an end of the motor for preventing an axial movement of the motor, the guiding member comprising at least a leg extending along an axial direction thereof into the lens unit for guiding the axial movement of the lens unit;
- wherein a protrusion extends radially and outwardly from an outer periphery of the guiding member, the protrusion being sandwiched between the motor and lens mount to prevent the axial movement of the motor;
- and
- wherein a through hole is defined in the lens mount for extension of the guiding member therethrough, a flange extending upwardly from a circumference of the through hole along an axial direction of the lens mount for radially positioning the guiding member, the guiding member abutting against an inner surface of the flange.
A motor structure with a built-in lens comprising:
- a lens mount having a top cover and a bottom cover connecting together to define a chamber therein, the top cover defining a through hole;
- a motor mounted in the chamber, having a stator and rotor rotatably mounted in the stator, the rotor having an internal thread;
- a supporting member mounted between the bottom cover and the rotor whereby the rotor is rotatably supported by the supporting member;
- a guiding member mounted between the top cover and the rotor whereby the rotor rotatably engages with the guiding member, the guiding member having a portion located in the through hole;
- and
- a lens unit received in the rotor and having external thread engaging with the internal thread, the guiding member having a plurality of elongate legs extending downwardly to fit in grooves defined in the lens unit;
- wherein when the rotor rotates, the lens unit moves linearly through the through hole of the top cover surrounded by the guiding member.
