The light-operated motor comprises two photoelectric sensors and one and-gate logic-gate computing device, output ends of the two photoelectric sensors are respectively electrically connected with an input end of the and-gate logic-gate computing device, the and-gate logic-gate computing device is electrically connected with the motor, two ends of a lower rim of the projection screen are respectively provided with a mounting seat, each mounting seat is provided with a photoelectric sensor, the photoelectric sensors output high levels when being illuminated by light greater than or equal to an a lumen, the photoelectric sensors are provided with controllers capable of adjusting a value of the a in a positive number scope, the motor starts to uncoil the projection screen when the and-gate logic-gate computing device outputs the high level, and the motor starts to coil the protection screen when the and-gate logic-gate computing device outputs the low level. The light-operated motor can realize automatic coiling and uncoiling of the projection screen according to a state of a projector.
Description
Technical field
The utility model 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 utility model 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 utility model 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 respectively with the input end of gate logic door arithmetical unit, be electrically connected with 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.
Use controller to regulate the value of a according to the model difference of projector and ambient conditions, 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.In the time 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 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, and slip lid can hide photoelectric sensor, leave between the position of photoelectric sensor and slide along chute.Need to close the function of projection screen under light-operated motor automatic releasing time, only need with slip lid shield light electric transducer.
Adopt after technique scheme, the utlity model has following advantage:
Light-operated motor can be according to the state automatic deploying and retracting projection screen of projector.
Brief description of the drawings
