Zusammenfassung: | The utility model discloses an intelligent touch type elevator call-out part which comprises a main machine, a touch screen, a liquid crystal displaying screen and a conversion interface plate. The touch screen, the liquid crystal displaying screen and the conversion interface plate are connected to the main machine. The touch screen comprises a circuit board arranged on the back face of the touch screen, a liquid crystal displaying screen and a conversion interface plate. The back face of the circuit board is toward the liquid crystal displaying screen. The circuit board extends out of the outer edge of the liquid crystal displaying screen, and steps are formed. A plurality of through holes are formed in the part, extending out of the liquid crystal displaying screen, of the circuit board. Infrared receivers or infrared emitters are arranged in the through holes. Welding spots of the infrared receivers or the infrared emitters penetrate through the through holes and are welded with a circuit on the front face of the circuit board. The front face of the liquid crystal displaying screen is provided with four light-transmitting strips which define a square quadrangle. The light-transmitting strips are placed above the infrared emitters or the infrared receivers and are provided with blind holes for containing the infrared emitters or the infrared receivers. Reflecting faces are arranged in the light-transmitting strips. Angles of 45 degrees are formed between the liquid crystal displaying screen and the light-transmitting strips. The reflecting faces are placed in the direction right opposite to the infrared emitters or the infrared receivers. |
