Ultra thin type elevator calling box

Abstract

The invention relates to an ultra thin type elevator calling box and a button circuit thereof, which comprise buttons and an encloser of a display device, wherein the encloser is provided with a displThe invention relates to an ultra thin type elevator calling box and a button circuit thereof, which comprise buttons and an encloser of a display device, wherein the encloser is provided with a display window and button through holes, the display window corresponds to a display window of a shell, the button through holes are respectively used for the buttons to penetrate through and extend; a disay window and button through holes, the display window corresponds to a display window of a shell, the button through holes are respectively used for the buttons to penetrate through and extend; a display module is arranged on the front face of a printed circuit board (PCB), the PCB is fixedly connected with the encloser, and the display module corresponds to the display window of the encloser andplay module is arranged on the front face of a printed circuit board (PCB), the PCB is fixedly connected with the encloser, and the display module corresponds to the display window of the encloser and the display window of the shell when the PCB is arranged in a containing zone of the shell; and an electric component and a button contact device are arranged under the front face of the PCB. The elethe display window of the shell when the PCB is arranged in a containing zone of the shell; and an electric component and a button contact device are arranged under the front face of the PCB. The elevator calling box performs ultra thin design to the display device, and thins the display device because the prior electric component is moved to the front face of the circuit board from the back facevator calling box performs ultra thin design to the display device, and thins the display device because the prior electric component is moved to the front face of the circuit board from the back face of the circuit board and is downwards moved into the original vacant space, thereby solving the thickness problem of the elevator non-bottom calling box. The invention integrates the button device inof the circuit board and is downwards moved into the original vacant space, thereby solving the thickness problem of the elevator non-bottom calling box. The invention integrates the button device into the display device, simplifies the button structure and also solves the problems of space, thickness, resilience hand feeling and cost of the button.to the display device, simplifies the button structure and also solves the problems of space, thickness, resilience hand feeling and cost of the button.

Description

technical field [0001] The invention belongs to the technical field of elevator accessories manufacturing, and in particular relates to an ultra-thin elevator calling box and a button circuit thereof. Background technique [0002] In an elevator building, each floor needs to be equipped with at least one elevator call box, which is used to call the elevator up and down. For the structure of the current elevator bottomless call box, see Figure 1-5 , which includes a bottomless casing 1 , a display cover 2 , a button device 3 , and a display device 4 . The display device 4 usually includes three parts: a display module 41, a PCB circuit board 42 and 43 electronic components, such as Figure 4 , 5 As shown, the display module 41 is stacked on the front surface of the PCB circuit board 42 , and the electronic components 43 are stacked on the back side of the PCB circuit board 42 . see Figure 5 , the total thickness of the display device 4 is the sum of the thickness t1 of ...
