Abstract
An actuating motor set includes a mounting base; a motor; a transmission set including a worm gear formed with a tooth, wherein two opposite ends of the worm gear respectively defining are a pushing end and a restoring end; and a spring including an engagement part and an abutment part. The engagement part is engaged with the tooth, and an inner diameter of the abutment part is larger than an outer diameter of the tooth. The spring is pushed spirally by the tooth upon rotation of worm gear, and thus moving back and forth on an axial direction of the worm gear. The spring idles when it is moved to the pushing end due to lack of engagement therewith, and the spring also idles when it is moved the restoring end due to lack of engagement therewith.
Claims19
An actuating motor set of an electronic lock, comprising:
- a mounting base formed with a chamber;
- a motor connected to said mounting base and having a rotating shaft;
- a transmission set having a worm gear connected to said rotating shaft, said worm gear having a tooth distributed not all the way to two opposite ends respectively defining a pushing end and a restoring end;
- and
- a spring including an engagement part engaging with said tooth and a remaining part defining an abutment part, an inner diameter of said abutment part being larger than an outer diameter of said tooth;
- wherein, said spring is pushed spirally by said tooth upon rotation of said worm gear, and thus moving back and forth in an axial direction of said worm gear, said spring being idle when it is moved to said pushing end of said worm gear due to lack of engagement therewith, and said spring being idle when it is moved said restoring end of said worm gear due to lack of engagement therewith.
