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.
Summary of the invention
Technical problem to be solved by this invention 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 present invention 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 invention has the advantages that: through on the brake clutch, magnet being set; Make thus after the motor dead electricity; The magnetic attraction that has only magnet that the top brake is produced; 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 present invention 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.
Clutch 3 comprise have a certain interval be oppositely arranged top brake 31 and bottom brake 32; The brake axle 33 of bottom brake 32 makes bottom brake 32 to rotate around brake axle 33 in the middle of being arranged on bottom brake 32, and brake axle 33 passes coil combination 34 and is connected with reduction box 2.Coil combination 34 comprises coil and coil holder, and coil is dc coil preferably, is loaded in the coil holder.Brake axle 33 passes coil, and double as is an iron core, has strengthened magnetic field, has increased magnetic attraction.Top brake 31 and brake clutch 35 couplings and synchronous the rotation; The outstanding hole of passing shape correspondence in the brake 31 of top, the lower end of brake clutch 35; Embed on the brake clutch 35 magnet 36 is arranged; Preferably; Magnet 36 is embedded on the contact-making surface of brake clutch 35 and top brake 35; To guarantee stronger magnetic attraction, referring to Fig. 5.Break away from completely in order to ensure top brake 31 and bottom brake 32, magnet 36 evenly distributes on brake clutch 35, and preferred, magnet 36 is cylindrical.Top brake 31 is processed for magnetic conductor, and is preferred, is steel, makes magnet 36 can attract top brake 31.32 of bottom brakes are preferably processed like silicon rubber, 36 pairs of bottoms brakes of magnet, 32 generation attractions when avoiding hypotelorism.Brake axle 33 stretches out outside the brake clutch 35 after being upward through bottom brake 32 and top brake 31, and at the two ends of brake axle 33 jump ring 37 is set, to prevent the relative motion about these parts take place.
