Like notice of authorization is the disclosed a kind of electrically driven curtain of Chinese patent of CN2799824Y; Be arranged at the transmission component in the Curtain top rail; Include motor, power transmission shaft, flexibility connector and pin joint seat, motor has a rotary power axle, and power transmission shaft is articulated in rail inside through pin joint seat; One end is connected with the rotary power end of motor through the flexibility connector, through being connected to the blade of the stay cord drive curtain on the power transmission shaft.

Yet, this curtain, the motor that drives usefulness is arranged on an end of rail usually, drives curtain through an output shaft, and the easy like this two ends of curtain that cause receive force unbalance, and sensitive for damages has thus influenced application life of curtain.

The utility model content

The utility model technical problem to be solved provides the motor-driven curtain of a kind of employing double output shaft, makes the two ends stress equalization of curtain to have prolonged application life.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of double output shaft electrically driven curtain; Comprise rail and the transmission mechanism that is arranged in the rail, it is characterized in that said transmission mechanism comprises the double output shaft motor; The two ends of said double output shaft motor all have output shaft; Said output shaft is connected to an end of swingle, and the other end of said swingle is connected to ropewinder, and said double output shaft motor is electrically connected to journey controller.

Said output shaft is connected to an end of said swingle through intermediate connector, makes output shaft to install with convenient with the swingle coupling of different model thus.

Preferably, the speed reducing ratio of the reduction box of said double output shaft motor is consistent, and said output shaft rotates synchronously.

Said journey controller comprises an electronic circuit board; Said electronic circuit board is provided with control module; Be connected with stroke detection module that detects and calculate said double output shaft motor range and the wireless communication module that receives user's guidance command on the input of said control module, be connected with inverting module on the output of said control module to control said double output shaft motor forward or reverse.Thus, can control the running of motor according to user's order, thereby control opening or closing of curtain, stroke limit also can be protected motor and curtain simultaneously.

Said control module is supplied power thereby convert civil power to control module required voltage by reduction voltage circuit through the reduction voltage circuit power supply.

Said stroke detection module receives the hall signal of said double output shaft motor to detect and to calculate stroke, and the signal that records through the Hall element by motor calculates stroke.

The two ends of said double output shaft motor are provided with the fixed support that flexible material is processed, and the perforation that said output shaft passes on the said fixed support is connected with said intermediate connector.Both can play the effect of support, again can be shockproof, reduce influence to the motor operate as normal.

Compared with prior art, the advantage of the utility model is: replace traditional single output shaft motor with double output shaft motor-driven curtain, make that the stressed of curtain two ends can be balanced, avoided motor and curtain to be damaged effectively, prolonged application life.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Referring to Fig. 1 and Fig. 2, a kind of double output shaft electrically driven curtain, curtain comprises the honeycomb fashion abat vent, horizontal blind; The vertical louver curtain, wooden louvres curtain etc., this sentences horizontal blind is example; Comprise rail 1, be arranged on the transmission mechanism 2 in the rail 1, and the blade 3 that is arranged on rail 1 below.

Transmission mechanism 2 comprises double output shaft motor 21; With the fixing fixed support 22 that is arranged on double output shaft motor 21 two ends of last rail 1; Be used for double output shaft motor 21 is fixed, preferably process, both can play the effect of support by flexible material; Again can be shockproof, reduce influence to the motor operate as normal.Usually, double output shaft motor 21 is fixed on the centre of rail 1, stressed with balance curtain two ends.The two ends of double output shaft motor 21 all have output shaft 23, and are preferred, and the speed reducing ratio of the reduction box of double output shaft motor 21 is consistent, makes output shaft 23 to rotate synchronously.The perforation that output shaft 23 passes on the fixed support 22 is connected with intermediate connector 24, and is connected with an end of swingle 25 through intermediate connector 24.The other end of swingle 25 is connected in the ropewinder 26, and the stay cord 27 on the ropewinder 26 is connected with blade 3.

Double output shaft motor 21 is electrically connected to journey controller 4, and in the present embodiment, journey controller 4 also is arranged in the rail 1.Alternately, journey controller 4 also can be installed on the wall on curtain limit.Journey controller 4 comprises an electronic circuit board, and electronic circuit board is provided with reduction voltage circuit 41, is used for converting civil power into control module 42 needed voltages, thereby is control module 42 power supplies; The output of control module 42 is connected with inverting module 43, and inverting module 43 is connected to motor drive module 44, is used to make double output shaft motor 21 forward or reverse, to realize the up-down of blade 3.Also be connected with stroke detection module 45 and wireless communication module 46 on the input of control module 42, wherein, stroke detection module 45 is used to receive hall signal or the infrared signal that double output shaft motor 21 transmits, with the detection computations motor range; Wireless communication module 46 is used to receive user's guidance command, and with these command transfer to control module 42, carry out corresponding action according to order with control double output shaft motor 21 by control module 42.

When control module 42 receives user's instruction, as open curtain, then drive 21 runnings of double output shaft motors through motor drive module 44, the output shaft 23 at two ends drives intermediate connectors 24 and rotates with swingle 25, rotates thereby drive ropewinder 26.The rotation of ropewinder 26 makes that the stay cord 27 on it is wound on the ropewinder 26 gradually, rolls thereby drive blade 3.Simultaneously; Hall element in the double output shaft motor 21 or infrared sensor detect the rotation of double output shaft motor 21 and detected signal are sent to stroke detection module 45; Stroke detection module 45 is calculated the stroke of double output shaft motor 21; When reaching up stroke point, this signal is transferred to control module 42 controls double output shaft motor 21 thus and shut down.If the user sends through remote controller again in this process and ceases and desist order, then control module 42 stops double output shaft motor 21 according to this order, and 45 current strokes of record of stroke detection module are so that the control of the operation of curtain after this.

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 domain of the utility model.
