Description

A kind of controller for motor

Technical field

The utility model relates to a kind of motor running control device, specially refers to the controller for motor that is used on curtain, projection screen, the electric iron rolling door.

Background technology

At present, the structure and the pattern of control curtain are numerous on the market, but no matter hold court from behind a screen, shutter, roman shade still is that any other is vertical, move horizontally the structure design of mode, the stay cords that use are controlled mobile more, one end of stay cord usually the upper beam position with hold court from behind a screen, shutter or roman shade are connected, the other end is then from the upper beam position that both hands can move to that hangs, when the pulling stay cord, can control and hold court from behind a screen, shutter or roman shade are done horizontal or vertical moving, the design of this use stay cord, the back is installed has an outstanding rope in a side of curtain, not only not attractive in appearance, and also irregular swing can take place when moving in wind, can twine the people in some cases, particularly to child, even can snarl the danger of neck, so security performance is not high.

In order to improve the defective that curtain uses stay cord, a kind of new Window curtain structure appears on the market, and drive the curtain sheet by motor and do horizontal or vertical moving, cooperate infrared receiver and remote controller to replace stay cord again.But because the distance that can transmit of infrared rays is too short, if curtain is excessive, too high, perhaps the operator is apart from far away, usually can remote control less than; Other as projection screen or electric iron rolling door in the control lifting, also can take place same because the excessive remote control of distance less than problem.

Therefore, be necessary to develop send a kind of can increase the motor remote control distance, be used for the controller for motor on curtain, projection screen, the electronic iron volume.

The utility model content

The utility model provides a kind of controller for motor that can increase the motor remote control distance at above-mentioned purpose.

The technical scheme that the utility model is realized is:

Design a kind of controller for motor, motor inside is provided with the infrared rays reception antenna, motor one side is provided with first connecting portion and second connecting portion, and this first and second connecting portion can be subjected to being arranged on the control of the changeover switch on the motor and generation effect respectively, and first connecting portion is connected with and is used for the sensing converter that the sensing wireless signal converts infrared signal to.

The sensing converter is connected with first connecting portion of motor with transmission line, is provided with infrared rays transmitting antenna, wireless receiving antenna in the sensing converter and is used for wireless signal is converted to the control circuit of infrared signal.Control circuit in the sensing converter comprises signal conversion chip and the reception module, buzzer, the register that are connected with conversion chip.

Be connected with infrared receiver on second connecting portion.Be provided with infrared rays reception antenna and infrared rays transmitting antenna in the infrared receiver.

Control motor operations by the sensing controller that changeover switch selects first connecting portion to connect, or the infrared remote receiver that second connecting portion connects is controlled motor running.

The utility model has following remarkable result compared to existing technology:

This device motor and sensing converter are used, and can strengthen command range effectively, allow the operator can both easy manipulation in place far away.

In the innovation design multiple modes of operation can be arranged, use is connected with the motor of sensing converter, allow wireless signal convert infrared signal to by this sensing converter, and then the running of control motor, motor is subjected to the control of wireless signal will increase the distance of control greatly, is adapted at upward uses such as the big curtain of metric space; And the motor in this structure can also link to each other with infrared receiver, can also convert infrared rays control as required to, is adapted at the little occasion of metric space and uses, and is practical.

The specific embodiment

The controller for motor that the application protected can be applied to the lifting of controlling curtain on the curtain, also can be applied to the lifting of control screen on the projection screen, can also be applied to the lifting of control iron rolling door on the electric iron rolling door etc.

Below describe by this controller for motor being installed in use to example on the curtain.

Referring to Fig. 1 to Fig. 4, it includes: a motor 10 and a sensing converter 20, wherein, motor 10 is contained in upper beam 31 positions of curtain 30, be used for driving 32 liftings of curtain sheet, motor 10 inside are provided with infrared rays reception antenna 11, one sides and are provided with first connecting portion 12 and second connecting portion 13, and first and second connecting portion is subjected to changeover switch 14 controls to come switch operating.Sensing converter 20 utilizes transmission line 21 to link to each other with first connecting portion 12 of motor 10, sensing converter 20 be provided with infrared rays transmitting antenna 22 and wireless receiving antenna 23.The sensing converter inside is provided with the control circuit that wireless signal is converted to infrared signal, and the control circuit of switching signal can adopt existing general conversion control circuit.Control circuit that present embodiment adopts comprises conversion chip 26, and conversion chip links to each other with electric control elements such as electric capacity, resistance, inductance, reception module 24, register 25 and buzzers 27.After sensing converter 20 receives wireless signal, just can utilize its internal electrical control elements to convert wireless signal to infrared signal, thus the running of control motor 10.

In conjunction with Fig. 3 and Fig. 4 as can be seen, when reality is used, the operator produces wireless signal with remote controller 40, sensing converter 20 then can receive this wireless signal with wireless receiving antenna 23 and reception module 24 synchronously, and after being decoded, convert wireless signal to infrared rays control sign indicating number through conversion chip 26 again, infrared rays control sign indicating number sends infrared rays reception antenna 11 in the motor to via the infrared rays transmitting antenna 22 in the sensing converter again, thereby the control motor just, de-rotation, curtain sheet 32 is correspondingly rolled-up or put down, like this, just can utilize wireless signal to have controls higher than the characteristic of the defeated distance of teletransmission, moving of curtain 30 at a distance.

The above is that the first connecting portion place connects the situation that the sensing controller is controlled motor operations, the following describes another pattern of controlling motor running at second connecting portion place connection infrared remote receiver.

Shown in Figure 5, motor 10 also can not adorned sensing converter 20, but directly an infrared receiver 50 is linked to each other with motor 10 second connecting portions 13, have infrared rays reception antenna and infrared rays transmitting antenna in this infrared receiver 50 equally, come switching controls to make the motor second connecting portion work by changeover switch 14, thereby convert motor 10 to pattern by infrared receiver 50 controls.Less when curtain 30 installing spaces, perhaps put the beams in place 31 itself when low, just can select this infrared rays control model, thereby the realization different operation modes is operated.

According to the foregoing description as can be known, this controller for motor can strengthen command range effectively when select using the sensing converter to cooperate with motor, allows the operator also can easy manipulation in place far away; And select motor is linked to each other with infrared receiver, then can convert infrared signal to and control motor operations, make this structure under the prerequisite that does not change original design, reach the purpose of multiple use pattern operation, have more flexibility and practicality.
