The utility model content:
The purpose of this utility model is intended to overcome the deficiencies in the prior art, provides a kind of simple in structure, can effectively solve band USB interface that computing machine and data that counter produces and information switch mutually and the counter with computer-aided keypad function.
The utility model is mainly realized goal of the invention by following technical solution:
A kind of it comprises the counter housing of being made up of panel and drain pan, is located at button and LCD display on the panel with USB interface and counter with computer-aided keypad function, is located at the wiring board in the counter housing; Be connected with wiring board by conductive adhesive layer with key position corresponding key seat, LCD display is electrically connected with wiring board, also comprises USB interface, and described USB interface is electrically connected with wiring board.
Wherein said USB interface comprises a communication USB port and three expansion USB HUB ports, and a described communication USB port and three expansion USB HUB ports are electrically connected with wiring board respectively.
Wherein said panel is provided with a sun power sheet, and the sun power sheet is electrically connected with wiring board.
The utility model beneficial effect is: the utility model is simple in structure, and it comprises the counter housing, the wiring board in the button, LCD display and counter housing; Also comprise USB interface, USB interface is electrically connected with wiring board.Because the setting of USB interface, the utility model can realize effectively and the docking of computing machine that between is realized the mutual switching and the coordination of information and data, and the utility model is used as an auxiliary keyboard of computing machine, thereby greatly reduced repeated workload, improved work efficiency.In addition, the utility model also is provided with a sun power sheet, and sun power is converted to electric energy, reduces the use amount of battery, and is environmental and ecological.

Embodiment:
Below in conjunction with accompanying drawing the technical solution of the utility model is described further:
As shown in Figure 1 and Figure 2, the utility model is a kind of with USB interface and counter with computer-aided keypad function, it comprises the counter housing that is composed of a fixed connection by screw 7 by panel 1 and drain pan 5, button 2, LCD display 9 and sun power sheet 11 all are located on the panel 1, wherein LCD display 9 and sun power sheet 11 respectively be located at the counter housing in wiring board 4 be electrically connected; Being connected with wiring board 4 by conductive adhesive layer 3 with button 2 position corresponding key seats 19, also is that conductive adhesive layer 3 is located on the wiring board 4, and 19 of key bases are located on the conductive adhesive layer 3.In addition, also be provided with on the wiring board 4 outside 10, two pushings of two pushings, 10 extending panels 1, be lined with pad between pushing 10 and the panel 1, pushing 10 mainly plays switch or function and switches.
The utility model also is provided with a battery case 13 except being provided with a sun power sheet 11, be used for the device power-supply battery, and battery compartment door 6 is used to close battery case 13; Sun power sheet 11 alternately provides power supply with power-supply battery, can provide at sun power sheet 11 under the situation of power supply, generally provides without power-supply battery, to reduce the use amount of power-supply battery, reaches the purpose of energy-conserving and environment-protective.
The utility model also comprises USB interface 8, and USB interface comprises that a communication USB port 21 and three expansion USB port 22, one communication USB21 ports and three expansion USB22 ports are electrically connected with wiring board 4 respectively.
As shown in Figure 3, Figure 4, relevant information or data are imported from keyboard 18 by the user, keyboard 18 dependent instructions send to master cpu chip 14 and control, master cpu chip 14 is mainly used to coordinate the running of various piece, handle computing, the information of process user input and output relevant treatment result, relevant treatment result send LCD display 9 to by master cpu chip 14 and show, in addition, LCD display 9 also shows the information such as connection status of the utility model and computing machine; Cpu chip 14 can send to the relevant treatment result usb communication chip 15 simultaneously, passes to communication USB port 21 by usb communication chip 15 again, thereby is transferred to main frame 20 at last; On the contrary, relevant information on the main frame 20 and result also can through usb communication chip 15 and master cpu 14, finally show in LCD display 9 by communication USB port 21.So just realized the mutual switching of information and date between computing machine and the utility model, realized that the utility model is as the computer-aided keypad function.In addition, usb communication chip 15 connects three expansion USB port 22 by USB HUB chip 16, directly expanded the USB HUB port number of computing machine, can make computing machine will more be correlated with effectively USB device by the expansion USB port be integrated and connected, easy to operate.
The utility model can combine together with computing machine, fully realizes the mutual switching of the utility model and computer related information and data, reduces and repeats work, greatly increases work efficiency.In addition, directly expanded the USB HUB port number of computing machine, can make computing machine connect more USB external unit.
