As shown in fig. 1 to 4, the manual door lowering system of the roller shutter door motor comprises a motor casing 1, wherein a motor rotating shaft 2 for driving the roller shutter door to move is arranged in the motor casing 1. The motor rotating shaft 2 rotates under the action of a motor, so that the door body is driven to move up and down. The landing door system further comprises a brake shell 3, a positioning shaft 4 and a sleeve 41 sleeved on the positioning shaft 4, wherein the positioning shaft 4 translates along the sleeve 41 so as to ensure the activity track of the landing door system. The brake housing 3 is located on one side of the motor housing 1, the positioning shaft 4 passes through the inside of the brake housing 3, and the sleeve 41 is sleeved on the positioning shaft 4 and can move along the positioning shaft 4. The sleeve 41 is close to the brake shell 3 open end and is equipped with brake block 42, and brake block 42 is close to sleeve 41 one side and is equipped with the electromagnetic conversion system 5 that drive brake block 42 is movable, and brake block 42 is close to brake shell 3 open side and is equipped with brake disc group 6, has still cup jointed spring 43 on the locating shaft 4, and spring 43 is coaxial with sleeve 41 and spring 43 one end offsets with sleeve 41. The brake disc group 6 is sleeved on the motor rotating shaft 2 for driving the rolling shutter door to move, the brake disc group 6 comprises a friction plate 61 and a brake disc main body 62 which are parallel to the brake pad 42, at least two throwing blocks 63 are connected to the brake disc main body 62, and a tension spring 64 is connected between every two adjacent throwing blocks 63. The brake pad 42 is fixed on the sleeve 41, and in the electrified state, the suction force of the electromagnetic conversion system 5 on the brake pad 42 enables the brake pad 42 to keep a certain gap with the brake disc group 6, and at the moment, the door body normally moves up and down under the driving action of the motor; when the door body stops at a designated height, the electromagnetic conversion system 5 stops working, and the return spring 44 pushes the brake pad 42 to move so as to make the brake pad contact with the friction plate 61, and the friction force between the brake pad and the friction plate is balanced with the weight of the door body and keeps the door body stationary. When the power is off, the electromagnetic conversion system 5 does not generate load on the brake pad 42, the brake pad 42 is in contact with the friction plate 61 under the action of the return spring 44, at this time, the sleeve 41 is moved to enable the return spring 44 to be compressed, and further the brake pad 42 is separated from the friction plate 61, at this time, the door body descends under the action of dead weight, the motor rotating shaft 2 and the brake disc group 6 rotate along with the door body, when the descending speed reaches a certain value, the throwing block 63 throws out under the action of centrifugal force and contacts and rubs with the inner side surface of the brake shell 3, and the friction force is balanced with the gravity of the door body finally, so that the door body falls at a stable speed.

The opening limits the rotational movement of the boss 422 and thus the rotation of the brake pad 42. The electromagnetic conversion system 5 includes a core 51 and a coil 52 located within the core 51, the axis of the coil 52 being perpendicular to the brake pads 42. The coil 52 is also provided with a coil 52 bracket having an I-shaped cross section.
The brake disc main body 62 comprises a transmission part 621 sleeved on the motor rotating shaft 2 and rotating along with the motor rotating shaft 2, a friction part 622 positioned at the outer edge of the transmission part 621, the friction part 622 is in fit contact with the friction plate 61, and the brake disc main body 62 further comprises a protruding part 623 propped against the throwing block 63. The protruding portions 623 are hinged to the brake disc main body 62, and the tension springs 64 are located between the protruding portions 623, so that the brake disc main body 62 does not interfere with the tension springs 64. The thickness of the transmission part 621 is larger than that of the friction part 622, the moment generated in the process of contacting the throwing block 63 with the brake shell 3 is large and the direction is irregular, and the transmission part 621 is sleeved with the motor rotating shaft 2 so as to ensure the stability of the rotating position of the brake disc main body 62. The sensitivity of the drop gate system can be changed by replacing the friction plate 61, and the situation that the friction plate 61 is severely worn after long-term use can be dealt with. The friction plate 61 may be made of a rubber material or a fiber material and is bonded to the surface of the friction portion 622 by cementing. In this embodiment, the number of the swing blocks 63 is two, the swing blocks 63 include swing block brake pads 631 near one side of the brake housing 3, and the swing block brake pads 631 include arc friction surfaces, the friction surfaces being disposed toward the inner side surface of the brake housing.
The baffle 32 is arranged in the brake shell 3, the baffle 32 comprises a convex block positioned in the middle, the sleeve 41 penetrates through the convex block, a flat plate is arranged between the convex block and the inner side wall of the brake shell 3, and a through hole for a circuit to penetrate is formed in the flat plate. A limit nut 411 is fixed on the sleeve 41, a door lowering rod 34 is sleeved on the sleeve 41 between the limit nut 411 and the partition plate 32, and the door lowering rod 34 comprises a sleeved part 341 and a spanner part 342 penetrating through the partition plate 32. The door lowering rod 34 is pulled towards the side far away from the motor casing 1, and the door lowering rod 34 rotates by taking the upper surface of the partition plate 32 as a fulcrum and presses the limit nut 411, so that the sleeve 41 drives the brake pad 42 to move. The end of the drop door lever 34 is located outside the brake housing 3 for easy operation. The brake housing 3 may be in a rectangular plate structure, one end of which is sleeved with the sleeve 41, and the other end of which is provided with an opening. Through which a crow bar or the like can be inserted, increasing the moment and facilitating handling on the ground. A gap is provided between the socket 341 and the outer surface of the sleeve 41, and the socket 341 abuts against the partition 32 and the limit nut 411 to increase the amplitude of movement of the door drop rod 34 to drive the sleeve 41.
A return spring 44 is arranged between the sleeve 41 and the rear cover 31, and a positioning clamp spring 45 is arranged at one end of the sleeve 41 close to the return spring 4443.
