Abstract
The invention discloses a light-operated motor and belongs to the field of tubular motors. The light-operated motor solves the problem that the tubular motors applied to a projection curtain cannot collect or release the protection curtain automatically. The light-operated motor comprises two photoelectric sensors and a conjunction gate logic gate arithmetic unit, wherein the output ends of the photoelectric sensors are electrically connected with the input end of the conjunction gate logic gate arithmetic unit respectively, the conjunction gate logic gate arithmetic unit is electrically connected with the motor, installation seats are respectively arranged at the two ends of the lower edge of the projection curtain, and the photoelectric sensors are arranged on the installation seats. When light larger than or equal to alpha illuminates the photoelectric sensors, high level is output. Controllers capable of regulating alpha values within a positive number range are arranged on the photoelectric sensors, the motor starts to release the projection curtain when the conjunction gate logic gate arithmetic unit outputs high level, and the motor starts to collect the projection curtain when the conjunction gate logic gate arithmetic unit outputs low level. The light-operated motor can collect or release the projection curtain automatically according to states of a projector.
Description
Technical field
The present invention relates to tube shaped electric machine field, particularly a kind of light-operated motor.
Background technology
Tube shaped electric machine is often applied to controlling on the projection screen matching with projector, and existing projection screen needs the folding and unfolding of manual control projection screen, comparatively inconvenience.
Summary of the invention
The object that the present invention will reach is to provide a kind of light-operated motor, can be according to the switching automatic deploying and retracting projection screen of projector.
In order to achieve the above object, the present invention adopts following technical scheme: a kind of light-operated motor, comprise two photoelectric sensors and one and gate logic door arithmetical unit, the output terminal of two photoelectric sensors is electrically connected to respectively with the input end of gate logic door arithmetical unit, be electrically connected to motor with gate logic door arithmetical unit, light-operated motor also comprises two mount pads, two mount pads are located at respectively the two ends of projection screen lower limb, two photoelectric sensors are located at respectively on a mount pad, when being subject to being more than or equal to the illumination of a lumen, exports by photoelectric sensor high level, photoelectric sensor is provided with the controller that can regulate a value within the scope of positive number, during with gate logic door arithmetical unit output high level, electric motor starting puts down projection screen, during with gate logic door arithmetical unit output low level, electric motor starting is packed up projection screen.
According to the model difference of projector and ambient conditions, use controller to regulate the value of a, and if only if, and two photoelectric sensors are subject to enough illumination simultaneously and send high level signal when with gate logic door arithmetical unit, with gate logic door arithmetical unit output high level.When starting projector, projector projects illumination is to the photoelectric sensor that is suspended from projection screen below, photoelectric sensor receives that illumination control electric motor starting puts down projection screen, projector cuts out rear photoelectric sensor loss of gloss, electric motor starting is packed up projection screen, two photoelectric sensors are located at respectively the two ends of projection screen lower limb, and by being electrically connected to and can preventing the equipment error starting motors such as electric torch with motor with gate logic door arithmetical unit.
Further, described mount pad is provided with chute and slip lid, slip lid can be along chute hiding photoelectric sensor, leave between the position of photoelectric sensor and slide.In the time of need to closing the function of projection screen under light-operated motor automatic releasing, only need with slip lid shield light electric transducer.
Adopt after technique scheme, tool of the present invention has the following advantages:
Light-operated motor can be according to the state automatic deploying and retracting projection screen of projector.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the schematic diagram of an embodiment of the present invention;
