Detailed Description

The present invention will be described with reference to the accompanying drawings and specific embodiments.

Referring to FIGS. 1-3:

an external curtain opening and closing component comprises an electric driver 1 and two lifters 2.

One electric drive 1 and two lifts 2 each comprise the following common components:

a seat 10; a top-open gear cavity 11 is arranged in the base 10, and a tail cavity 12 communicated with the gear cavity 11 in the front and back is arranged on the rear end surface of the base;

a gear shaft 20; the root gear shaft 20 is arranged in the gear cavity 11 in a front-back direction, and the rear end face of the root gear shaft is provided with a connecting hole 21;

a gear 30; the gear 30 is arranged in the gear cavity 11 and is sleeved on the gear shaft 20 through a wheel center hole, and the gear teeth on the side part of the gear 30 are exposed out of the top of the base 10;

a magnet 40; the magnet 40 is fixedly arranged in a groove arranged on the bottom surface of the base 10;

two pairs of rollers 50; the two pairs of rollers 50 are respectively arranged at four corners of the bottom surface of the seat 10 in a laterally rolling manner.

The front end of a gear shaft 20 on the electric driver 1 is rotatably arranged in a shaft hole arranged on the front wall of the gear cavity 11, the front part of the gear shaft is fixedly connected with the gear 30 to drive the gear 30 to rotate, and the rear end of the gear shaft is fixedly sleeved on an output shaft of a motor 60 arranged in the tail cavity 12 through a connecting hole 21 to be driven by the motor 60 to rotate.

The front ends of the gear shafts 20 on the two lifters 2 are fixedly arranged in shaft holes arranged on the front wall of the gear cavity 11, and the front parts of the gear shafts are movably connected with the gear 30 so that the gear 30 rotates around the gear.
