Abstract
The utility model discloses a hand-operated light structure for an opening and closing curtain motor, comprising a motor core, a reduction box and a clutch connected with the reduction box, wherein the clutch comprises an upper brake and a lower brake, the upper brake is matched with a brake linkage device, and the upper brake and the brake linkage device rotate synchronously. The hand-operated light structure for an opening and closing curtain motor is characterized in that a magnet is embedded into the brake linkage device, and the upper brake and the lower brake are arranged oppositely and spaced by a certain gap. The hand-operated light structure can be used for adjusting a curtain with a small force when the motor is in power failure.
Description
Technical field
The utility model relates to a kind of folding curtain motor, especially a kind of light structure of hand pull starting-up.
Background technology
The motor-driven open-close type curtain of existing use (folding curtain) drives the expansion and the gathering of curtain through the running of motor.When run into have a power failure or situation that power supply can't be supplied with under because the power output shaft of motor can't break away from outside transmission mechanism, thereby make the position that can't adjust curtain through the mode that pulls.
For this reason, people have studied in folding curtain motor clutch have been set, clutch can be electromagnetic type also can be mechanical.Under the situation of motor dead electricity, transmission mechanism can be independent of motor and move, and therefore can be provided with the function that pulls or have the hand pull starting-up function.Yet; Existing folding curtain motor with electromagnetic clutch is as depicted in figs. 1 and 2 usually; Motor core 1 ' connects reduction box 2 '; Brake 3 ' middle brake axle 4 ' in bottom passes coil combination 5 ' and is connected with the output of reduction box 2 ', and top brake 6 ' is also rotated with brake clutch 7 ' coupling synchronously, and motor output shaft 8 ' is fixed in brake clutch 7 ' and rotates and drive outside transmission mechanism rotation synchronously.
When electrical power moves, coil combination 5 ' electricly top brake 6 ' produced very strong magnetic attraction make top brake 6 ' and bottom brake 3 ' closely contact and drive top brake 6 ', brake clutch 7 ' and motor output shaft 8 ' rotation; When the motor dead electricity was out of service, the magnetic attraction of coil combination 5 ' disappeared, and top brake 6 ' breaks away from tight state of contact with bottom brake 3 ', top brake 6 ' also unable being rotated further, and motor output shaft 8 ' stops operating thus.This moment, outside transmission mechanism drove motor output shaft 8 ' with pulling moving curtain, made motor output shaft 8 ' also and then rotate and drive top brake 6 ' to rotate.Owing to do not have magnetic attraction between top brake 6 ' and the bottom brake 3 ',, realized the function that pulls when motor is out of service so bottom brake 3 ' can't be followed rotation.
Yet, though top brake 6 ' contact closely during not as energising with bottom brake 3 ' when the motor dead electricity,, have certain frictional force because both are still keeping certain contact, make need be bigger when manually spurring curtain power, be unfavorable for daily use.
The utility model content
The utility model technical problem to be solved provides a kind of folding curtain motor and pulls light structure, can when the motor dead electricity, use the less manual pulling curtain of power to adjust.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of folding curtain motor pulls light structure; Comprise motor core, reduction box, and the clutch that is connected with said reduction box; Said clutch comprises top brake and bottom brake; The brake of said top is mated with the clutch that brakes and rotated synchronously, it is characterized in that: be embedded with magnet on the said brake clutch, brake in said top and the brake of said bottom is oppositely arranged and keep certain clearance.
Break away from completely in order to ensure top brake and bottom brake, said magnet evenly distributes.
Preferably, magnet is cylindrical.
Said magnet is embedded on the contact-making surface of said brake clutch and said top brake, and the brake clutch applies stronger magnetic attraction to the top brake when guaranteeing dead electricity.
The brake axle of said bottom brake is passed down through coil combination and is connected with said reduction box, and said coil combination comprises coil holder and the coil that is loaded in the coil holder.Thus, the rotation of motor core can drive clutch.
Said brake axle stretches out outside the said brake clutch after being upward through brake of said bottom and the brake of said top, makes top brake, bottom brake and brake clutch all rotate around brake axle.
The two ends of said brake axle outside said brake clutch and said coil combination are respectively equipped with jump ring, to prevent the relative motion about above-mentioned parts take place.
Also comprise the motor output shaft of fixing and rotating synchronously with said brake clutch, said motor output shaft connects outside transmission mechanism.Thus, driving the curtain that is connected with transmission mechanism launches or gathering.
Compared with prior art; The advantage of the utility model is: through on the brake clutch, magnet being set, make after the motor dead electricity to have only the magnetic attraction of magnet to top brake generation thus; Thereby the brake of attraction top is close to the brake clutch and is separated with the bottom brake; No longer have frictional force between the two, pull curtain again and then can use less power this moment, made things convenient for operation.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Referring to Fig. 3 and Fig. 4, a kind of folding curtain motor light structure comprises motor core 1, reduction box 2, clutch 3 and motor output shaft 4.Motor core 1 is connected with reduction box 2, is provided with clutch 3 between reduction box 2 and the motor output shaft 4.
When folding curtain electrical power moves; Coil gets electric to the very strong magnetic attraction of top brake 31 generations; Be far longer than the attraction of the 36 pairs of top brakes 31 of magnet on the brake clutch 35; The attraction that makes top brake 31 overcome magnet 36 closely contacts and drives top brake 31, brake clutch 35 and motor output shaft 4 with bottom brake 32 and rotates, and realizes the synchronous rotation of motor output shaft 4 and brake axle 33.
When folding curtain motor dead electricity is out of service; The magnetic attraction of coil disappears; 36 pairs of top brakes 31 of magnet on the brake clutch 35 produce certain attraction; Make it be close to brake clutch 35 and thoroughly separate, maintain certain clearance, eliminated contact friction force between the two with bottom brake 32.At this moment, when manually spurring the curtain transmission mechanism again and driving top brake 31 and rotate, need not to overcome the frictional force between top brake 31 and the bottom brake 32 again, thereby make that the required power of manually pulling is less, made things convenient for operation.
The above is merely the preferred implementation of the utility model; Should be pointed out that for those of ordinary skill in the art, do not breaking away under the principle prerequisite of the utility model; Can also make various deformation and improvement, this also should be regarded as the protection range of the utility model.
