In order to thoroughly understand the utility model, detailed step and detailed structure will be proposed in following description,
To explain the technical solution of the utility model.Preferred embodiment of the present utility model is described in detail as follows, but except these
Outside being described in detail, the utility model can also have other embodiment.
Shown in reference picture 1- Fig. 4, the utility model provides a kind of transmission mechanism, including：
Reducing motor 1, the output shaft of reducing motor 1 are connected with motor gear 2；
Gear-box 3, gear-box 3 are provided with a gear wheel 4, planetary gear 5 are provided between gear wheel 4 and motor gear 2, preferably
For 3 planetary gears, planetary gear 5 engages with gear wheel 4 and motor gear 2 respectively, the output of gear wheel 4 and reducing motor 1
Axle is connected, it is possible to achieve when motor gear 2 rotates, tooth rest is motionless, and the rotation of gear wheel is driven by planetary gear 5；
The lower end of gear-box 3 is provided with tooth rest 6, and lower tooth wheel carrier 6 is connected with the output shaft of reducing motor 1, positioned at motor
The lower end of gear 2, with reference to shown in 4, gear wheel 4, lower tooth wheel carrier 6 are respectively fitted on the output shaft of reducing motor 1, the institute of reference picture 1
Show, lower tooth wheel carrier 6 is enclosed on the output shaft of the reducing motor 1, can be around the output shaft rotation of reducing motor 1；
Stopping means 7, stopping means 7 rotate for limiting lower tooth wheel carrier 6 on the output shaft of reducing motor, that is,
Say, when stopping means 7 works, lower tooth wheel carrier 6 can be limited and rotated on the output shaft of reducing motor 1.So as to realize
When reducing motor 1 does not work, when stopping means 7 does not also work, gear wheel can be rotated freely, when reducing motor 1 works,
Now also in working condition, so as to limit the rotation of lower tooth wheel carrier 6, now reducing motor rotates stopping means 7, drives row
The rotation of star gear, so as to drive bull gear drive, that is to say, that now, during the rotation of gear wheel turn with the rotation of motor
Dynamic, under the state, gear wheel can not be rotated freely.Can solve, in smart lock, when motor does not work, shank of the key due to by
To the resistance of reducing motor and situation about can not freely rotate, in the utility model, apply in smart lock, gear wheel connection
