Description

Curtain motor shell and circuit board mounting structure Technical Field The utility model relates to a curtain motor, in particular to a structure that a shell of the curtain motor and a circuit board are arranged on the shell. Background With the development of intelligent home, people increasingly use electric curtains to realize opening and closing of the curtains. The curtain motor is a power source for electric curtain, and the circuit board installed in the curtain motor is an important component. Most of the shells of the existing curtain motors are cylindrical or the cross section of the shells is rectangular, and the circuit board is vertically arranged and installed in the shells; meanwhile, in order to install the circuit board, a specific placing space is required to be arranged inside the shell, and a vertical clamping groove is arranged on the inner side of the shell to fix the circuit board. Although the circuit board can be stably installed, the curtain motor occupies more installation space, so that the curtain motor is large in size, the production cost is high, and the attractiveness of a curtain system and interior decoration is affected. Disclosure of utility model The utility model aims to provide a curtain motor shell and a circuit board mounting structure for transversely mounting a circuit board at the end part of the shell, so as to improve the mounting and dismounting convenience and reduce the volume of equipment.
