Positioning device based on mechanical counting of motor

Abstract

The invention discloses a positioning device based on mechanical counting of a motor, comprising a shell. The shell is internally provided with a driving gear, a clockwise gear set and an anticlockwise gear set, wherein the clockwise gear set and the anticlockwise gear set are fit with the driving gear; the clockwise gear set comprises a pair of differential gears which are arranged at the same axis and have different tooth numbers; the anticlockwise gear set comprises a pair of differential gears which are coaxially arranged and have different tooth numbers; the shell is also internally provided with a clockwise stroke regulating mechanism and an anticlockwise stroke regulating mechanism which are fit with the clockwise gear set and the anticlockwise gear set respectively; and the clockwise gear set and the anticlockwise gear set are arranged at the same axis. By using the positioning device based on the mechanical counting of the motor, the inner structure of the device can be effectively regulated, so that the inner structure is more compact, simultaneously, and the whole volume of the positioning device can be effectively reduced. The positioning device disclosed by the invention can be used in the positioning field of curtain machines.

Description

technical field [0001] The invention relates to a motor positioning device, in particular to a motor mechanical counting and positioning device. Background technique [0002] As a small household appliance, the driving motor in the electric curtain system requires a compact structure and a small volume so that it can be built into various decoration environments without adversely affecting the user's aesthetic feeling. Traditionally, mechanical structure counting limit devices have been used early, with accurate positioning, high reliability, and low cost. With the gradual maturity of modern electronic technology, multi-electronic limit systems have also appeared on the market, but in terms of cost and reliability. In terms of performance, it will be slightly inferior to mechanical positioning devices. [0003] In the positioning device of the mechanical structure, the differential technology of the gear set is used to solve the problem of the volume of the positioning devi...

AI Technical Summary

Problems solved by technology

[0004] Two sets of differential gears are used to control the travel of the positioning device in two directions. Due to its complex structure, it is inevitable that the volume of the positioning device cannot be effectively reduced. During the assembly process, the positioning device requires high assembly accuracy. resulting in an increase in its assembly cost
