Abstract
The utility model discloses a novel electric curtain, which comprises a rare earth permanent magnet direct current brushless motor, a gearbox, a driving wheel, a main transmission case, a secondary transmission case, an aluminum alloy track, a track, tackles, slip rings, diodes, limit switches and a switcher. The track, the tackles and the slip rings are drawn by using the rare earth permanent magnet direct current brushless motor to move in the main transmission case, the secondary transmission case and the aluminum alloy track through the driving wheel on the gearbox; and the operation stroke and the operation direction of the motor can be controlled by a control circuit consisting of the diodes, the limit switches and the switcher so as to drive curtain cloth to open or close.
Description
Technical field
The utility model relates to the electrically driven curtain of a kind of novel drive motors and stroke and direction control structure.
Background technology
Electrically driven curtain is a kind of modern times, fashion, household electronic product easily, is the indispensable part of household electronicization, mainly by driving part, control partly and traction partly constitute; Drive motors wherein and stroke and direction control are the cores of electrically driven curtain, and it not only is related to the complete machine performance indications, and noise vibration, also relates to main manufacturing cost at reliability and service life.
The electrically driven curtain of selling on the market mainly is power with the ac synchronous motor now, though advantages such as good stability, noise is little, the life-span is long are arranged, because of motor volume is excessive, overweight, after the curtain rail fixed in place, motor is installed again, last professional carries out stroke debugging, rather inconvenience.In addition, its stroke and direction control are undertaken by single-chip microcomputer or are adopted so-called " electronic intelligence " design, and two groups of parts such as high-precision difference position gear are controlled.Because the multiple bar of complete machine structure, technological requirement height make its price high for a long time, so generally in uses such as luxurious hotel, villas.
What the electrically driven curtain of another type used is brush direct current motor, and price is comparatively cheap; But because drawbacks such as the electric spark that carbon brush and commutator high-speed friction produce, noise, first line electrical interference, fault rate height, thereby can not get consumer's approval.
The utility model content
The purpose of this utility model is to overcome above-mentioned technological deficiency and a kind of high-performance is provided, cheaply the electrically driven curtain product.
Basic design of the present utility model is: rareearth permanent-magnet DC brushless electric machine by adopting excellent performance or rareearth permanent-magnet DC brushless external rotor motor are as the drive motors of electric curtain, crawler belt, coaster, slip ring motion in the driving wheel traction main transmission box on reduction gearbox output shaft, secondary transmission case, the aluminium alloy track; And, control the operation stroke and the traffic direction of above-mentioned motor by two diodes, two limit switches and the control circuit that change-over switch is formed, open and close to drive casement.
Compared with prior art, advantage of the present utility model is: since with the rare-earth Nd-Fe-B of high energy product as the drive motors rotor material, replace the carbon brush commutator with position sensor and realize electronic commutation, thereby have high torque (HT), high overload, low noise, efficient energy-saving, overlong service life (only being subject to bearing life); There are not a series of problems that cause because of brush; Since volume little, in light weight (less than ac synchronous motor 1/3rd), not because of motor separates the contingency question that causes with track, the work of getting final product of connecting with the mains after installing and fixing.And by two limit switches (forming) by a microswitch, two springs, link stopper and nylon mount pad, the circuit that two diodes (2CZ type) and change-over switch (one group interlocking uni-directional push-button switch or 12V two-way radio remote control switch) are formed, not only can control the operation stroke of electrically driven curtain effectively, the conversion operation direction, and reliable operation, with low cost, use very convenient.
Description of drawings
Fig. 1 is a circuit diagram of the present utility model
Fig. 2 is a structural representation of the present utility model
The specific embodiment
Provide embodiment of the present utility model below in conjunction with Fig. 1 and Fig. 2:
Connect power supply, allow the electric current forward flow by change-over switch (SA), dc brushless motor (1) just changes, drive the driving wheel (3) on reduction box (2) output shaft, traction main transmission box (8), secondary transmission case (9), crawler belt (5) in the aluminium alloy track (4), coaster (6), slip ring (7) motion, casement progressively draws back simultaneously; When slip ring (7) collided the limit switch (10) of track one end, circuit disconnected, motor (1) is out of service, the curtain cord is fully withdrawn.As want casement to close, then allow reverse direction current flow and limit switch (10) diode connected in parallel (D by change-over switch (SA)
2) forward conduction, motor (1) counter-rotating; The former limit switch that has disconnected (10) resets the closing of contact; When the coaster (6) of inverted running collides the limit switch (11) of track centre, circuit and disconnection again, motor (1) stall, casement is all closed; So repeatedly.In the open and close process, stop at an arbitrary position as the needs casement, click the S key and get final product.
