Description
Technical Field
The invention relates to an input channel switching mechanism, in particular to an input channel switching mechanism based on an electromagnetic clutch.
Background
In an electric mechanism, a motor is generally called an electric input channel of the electric mechanism when the motor drives an output mechanism to realize linear or rotary output by driving a speed reducer. In some electric mechanisms, in order to ensure the reliability of output, it is common to increase the reliability of operation of the electric mechanism by adding another motor or adding a mechanical input channel. The mechanical input channel is typically an input shaft that leaves a specific interface, which can be driven by a specific tool. The output mechanism may be driven through a backup electrical channel or a mechanical channel when the primary electrical channel fails. Therefore, it is necessary to synthesize and switch the input channels. In the conventional working method, different input channels are generally integrated and switched by a speed integration mechanism, and a commonly used speed integration mechanism is a planetary gear train. When the input is carried out through a certain input channel, the other channel must be ensured to be self-locked, so that each channel must have self-locking capability, and common self-locking methods comprise electromagnetic clutch self-locking, turbine worm self-locking and overrunning clutch self-locking. For example, a dual input channel electric mechanism typically requires two sets of self-locking mechanisms, which results in additional weight and reliability costs.

Preferably, the armature 16 is mounted on the engaging surface C7, and when the electromagnetic clutch is operated, the engaging surface C7 slides axially and is engaged with the engaging surface D12, and at this time, since the engaging surface B6 and the engaging surface C7 are fixedly connected, the input shaft a1 is disconnected, and the mechanism is input from the input shaft B13.

please refer to fig. 1, which is a schematic structural diagram of a preferred embodiment of an input channel switching mechanism based on an electromagnetic clutch according to the present invention. In the present embodiment, the present invention is based on an input channel switching mechanism of an electromagnetic clutch, and switching between different input channels is realized by the electromagnetic clutch and a sliding mechanism, and the input channel switching mechanism is composed of an input shaft a1, a meshing surface a2, a support A3, a bearing a4, a fastening nut 5, a meshing surface B6, a meshing surface C7, an input gear 8, a support B9, a bearing B10, a pre-tightening spring 11, a meshing surface D12, an input shaft B13, an electromagnetic clutch housing 14, an electromagnetic clutch coil 15, an armature 16, a bearing C17, an output gear 18, and an output shaft 19.

The meshing surface B6 is fixedly connected with the meshing surface C7 and can axially slide along the hole of the input gear 8. The input gear 8 is fixed to the carrier by means of bearings 10 to ensure that the input gear 8 cannot axially shift and can bear a certain axial load. The engagement surface D12 is fixedly connected with the input shaft B13. The electromagnetic clutch comprises an electromagnetic clutch shell 14, an electromagnetic clutch coil 15, an armature 16 and the like and is fixed on a support.
