Description

Automatic curtain controller

Technical field

The utility model relates to automatic curtain technical field, refers in particular to automatic curtain controller.

Background technology

Along with improving constantly of people's living standard, people more and more pay close attention to the quality of life, and various intelligentized daily necessitiess start to enter people's real life.The curtain that people use in the past, is only the difference existing above materials, when use, is all to adopt the mode that rope makes curtain stretch, draw in that pulls; Now, people have designed automatic control curtain, and people only need be by movement controller, just can a key realize curtain and stretch, draw in, and people can be sitting in from far distance controlled curtain, more hommization on the far sofa of window.

The automatic curtain of selling on the market now, it is generally the mode that adopts motor driven gear and drive curtain, gear and the output gear of driven by motor mesh together all the time, the shortcoming of this structure is: in the time having a power failure, or when people stand in window side and think manually to draw curtain, the engagement force of said gear cannot be resisted with hand-power, thereby the effect of freely manually drawing curtain cannot be realized.

Therefore, for these reasons, need to improve the control drive part (clutch) of existing automatic curtain.

Utility model content

The purpose of this utility model is to provide automatic curtain controller for the deficiencies in the prior art, and this automatic curtain controller can solve existing structure and have the defect that cannot realize automatic control and have concurrently simultaneously manual control.

For achieving the above object, the utility model is achieved through the following technical solutions:

Automatic curtain controller, includes output shaft, motor, electromagnet; On output shaft, be fixed with clutch-plate, the expansion link of electromagnet drives the push-pull piece that has transverse shifting, the lift plate that push-pull piece pushing tow vertically moves, and motor drives rotating shaft, the limiting section on rotating shaft top be arranged with can with the upper clutch-plate lower clutch-plate coordinating that offsets, lower clutch-plate is positioned on lift plate.

Push-pull piece is L-type structure, comprises vertical portion and transverse part, and vertical portion has the u-shaped mouth coordinating with the expansion link of electromagnet, and the both sides of transverse part all have acclivitous pushing part.

Lift plate is structure in the form of sheets, and middle part offers the hole wearing for rotating shaft, and the both sides of lift plate all have acclivitous top splenium, and this top splenium contacts cooperation with the pushing part of push-pull piece.

Upper and lower clutch-plate structure in the form of sheets, middle part offers mounting hole, and the both sides of upper and lower clutch-plate all have the protuberance that protrudes from lamellar body.

The limiting section on rotating shaft top also overlaps stator, and the top of limiting section is placed with flat spring, and stator cover is pressed on flat spring, and the two ends of flat spring offset with lower clutch-plate respectively.

The beneficial effects of the utility model are: when initial position, and electromagnet no power, lower clutch-plate does not contact with upper clutch-plate, and output shaft and rotating shaft do not link, and export shaft-driven curtain and can move under external force, realize the manual actuation control of curtain; Therefore, whether, no matter have a power failure, only otherwise start curtain controller, people can directly manually draw curtain; In the time that electromagnet is switched on, expansion link pulls push-pull piece to move, and by lift plate, lower clutch-plate, along upwards jack-up of rotating shaft, lower clutch-plate and upper clutch-plate offset, electric motor starting, and rotating shaft and output shaft interlock, drive curtain to move, and realizes the automatic control of curtain; Have advantages of simple in structure, easy to usely, have more human features.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described.

Seeing Fig. 1--Fig. 6, the utility model automatic curtain controller comprises: output shaft 11, support 12, motor 13, limiting section 14, electromagnet 15, expansion link 16, push-pull piece 17, lift plate 18, lower clutch-plate 19, stator 20, flat spring 21, upper clutch-plate 22, box body 23, hole 24, top splenium 25, U-shaped mouth 26, pushing part 27, mounting hole 28, protuberance 29.

Push-pull piece 17 is L-type structure, comprises vertical portion and transverse part, and vertical portion has u-shaped mouth 26, locates for the expansion link 16 of electromagnet 15, and the both sides of transverse part all have acclivitous pushing part 27.

Lift plate 18 structure in the form of sheets, it is porose 24 that middle part is offered, and the rotating shaft that this hole 24 drives for power supply machine 13 wears, and the both sides of lift plate 18 all have acclivitous top splenium 25, and this top splenium 25 contacts cooperation with the pushing part 27 of push-pull piece 17.

Upper and lower clutch-plate structure in the form of sheets, middle part offers mounting hole 28, and the both sides of upper and lower clutch-plate all have the protuberance 29 that protrudes from lamellar body.

Clutch-plate has two, and one of them is lower clutch-plate 19, and its mounting hole 28 matches with the limiting section 14 on rotating shaft top, and lower clutch-plate 19 is positioned on lift plate 18, rotates with the rotation of rotating shaft; Another one is upper clutch-plate 22, and it is fixed on output shaft 11; Lower clutch-plate 19, upper clutch-plate 22 are installed in opposite directions, and when resting position state, the protuberance 29 of lower clutch-plate 19, upper clutch-plate 22 misplaces.

The limiting section 14 on rotating shaft top also overlaps and has stator 20, the top of limiting section 14 is placed with flat spring 21, stator 20 covers are pressed on flat spring 21, and the two ends of flat spring 21 offset with lower clutch-plate 19 respectively, can make stable reset of lower clutch-plate 19 after generation deformation under elastic force effect.

When initial position, electromagnet 15 no powers, expansion link 16 is positioned at outside maximum position place, lift plate 18, lower clutch-plate 19 are positioned at its lowest position, lower clutch-plate 19, upper clutch-plate 22 do not contact, output shaft 11 does not link with rotating shaft, and the curtain that output shaft 11 drives can move under external force, realizes the manual actuation control of curtain; Therefore, whether, no matter have a power failure, only otherwise start curtain controller, people can directly manually draw curtain.

In the time that electromagnet 15 is switched on, expansion link 16 inwardly shrinks, pull push-pull piece 17 to electromagnet 15 1 side shiftings, when push-pull piece 17 moves, pushing part 27 act on top splenium 25 and by lift plate 18 along upwards jack-up of rotating shaft, lower clutch-plate 19 is upwards held up by lift plate 18, until this lower clutch-plate 19 and upper clutch-plate 22 offset, now, flat spring 21 is by lower clutch-plate 19 compressions; Motor 13 starts, drive shaft rotation, and lower clutch-plate 19, upper clutch-plate 22 are driven follows rotation, and output shaft 11 drives curtain to move, and realizes the automatic control of curtain.

The utility model foregoing " upper and lower, horizontal, longitudinal ", is all taking illustrated direction as reference, is not limited to this with reference to explanation.

Output shaft 11, electromagnet 15 are installed on support 12, and entirety is fixed in box body 23, and therefore not to repeat here for the technical scheme such as the structure of motor 13 drive shafts, control module, electric wire.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, and unrestricted the utility model practical range, the equivalence of doing according to structure, feature and principle described in the utility model claim therefore all changes or modifies, and all should be included in the utility model claim.
