CONTROL DEVICE FOR THE SWITCH Russian patent published in 2021 - IPC H01H5/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used as a drive for switches operating under conditions of vibration, linear and shock effects, as well as in emergency situations. The control device for the switch contains two electric motors kinematically connected through gearboxes, a differential mechanism, an input shaft with an output element made in the form of a gear rack mounted with the possibility of interaction with the gear wheel of the input shaft, a locking mechanism of the output element made in the form of rack teeth with the possibility of interaction with the teeth of the gear wheel of the input shaft, a spring, two stops installed with the possibility of interaction with a gear rack connected to one end of the spring, electric motor control circuits with four switches made mechanical with the possibility of controlling them by cams mounted on the input shaft, a locking mechanism made in the form of an unbalanced mass with the possibility of its interaction with a gear rack, stoppers installed with the possibility of interaction with one of the gears of the corresponding gearbox. In the locking mechanism, a V-shaped recess is additionally made on the side of the unbalanced mass facing the gear rack, with the possibility of its interaction with the gear rack to prevent its movement in the opposite direction during impact in the actuated position, and the unbalanced mass is installed with the possibility of rotation relative to the axis.

EFFECT: increase in the locking force of the output element and the exclusion of its movement in the opposite direction during impact in the actuated position.
