The invention relates to the technical field of curtain motors, and discloses a curtain opening and closing motor with a protection structure. The curtain opening and closing motor comprises a shell and a bottom cover, wherein the bottom cover is mounted at the bottom of the shell, a transmission mechanism and a protection mechanism are arranged in the shell, the transmission mechanism comprises aclutch, a reduction gearbox, a rotating shaft, a servo motor, a clamping block, a transmission shaft, a rubber pad, a mounting plate and a second bolt, the servo motor is fixed to the lower portion in the shell, the rotating shaft is in transmission connection with the upper portion of the servo motor, and the reduction gearbox is fixed to the position, above the servo motor, in the shell. According to the invention, a pressure sensor is fixed in a transmission groove, when a transmission shaft drives a driving shaft to rotate, the pressure sensor detects a certain pressure numerical value, and when a curtain or a tackle is clamped, the acting force between a transmission block and the transmission groove is increased, so that the pressure sensor detects a larger numerical value and transmits the larger numerical value to an electric control panel, and a servo motor can immediately stop working so as to prevent the servo motor or the reduction gearbox from being damaged.
Description
technical field [0001] The invention relates to the technical field of curtain motors, in particular to a curtain opening and closing motor with a protective structure. Background technique [0002] At present, the opening and closing curtain motor is usually composed of a motor, a reduction box, a head clutch device and a circuit control board. For a general opening and closing curtain motor, the circuit control board is placed in the rear cover, and the circuit control board is locked in the rear cover by screws. On the cover, the top of the opening and closing curtain motor is connected to the main transmission box on the side of the curtain rail. When the motor is running, it can drive the timing belt and then move the pulley to drive the curtain to open or close. [0003] However, during the operation of the motor, when the curtain is resisted or the trolley is stuck in the guide rail, the motor will continue to run in order to drive the curtain to open or close to the ...
