Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1 and Fig. 2, embodiment of the present utility model, a kind of display instrument 1 for electric motor car, display instrument 1 is trigger-type control structure, and circular color liquid crystal screen shows, the electric motor car meter specially of band USB output is highly integrated, compact conformation, easily installs;Waterproof antidetonation, degree of protection IP66.
Display instrument 1 includes having the waterproof case 10 of display panels 5, appliance circuit plate 20, the controller circuitry unit 40 that storage circuit 30 is connected with storage circuit 30 and the liquid crystal display circuit 50 being connected with controller circuitry unit 40 are set in appliance circuit plate 20, the mode key 60 that is all connected with liquid crystal display circuit 50 and on & off switch 70 are set on waterproof case 10, press mode key 60 and/or the multiple running information of electric motor car that on & off switch 70 can show on display panels 5.
Specifically, length is turned on the power by & off switch 70 (power key), and battery electric quantity, speed are according to the instantaneous display of running state of electric motor car;Single mileage, accumulative mileage etc. show according to the function selected.
Short press mode key 60 (MODE key), mapping function, the characters such as TIME, TRIP, ODO, DST, CHA, VOL are had to occur respectively, express time during display TIME, represent single mileage during display TRIP, represent accumulative mileage during display ODO, during display DST, represent remaining mileage (needing battery to coordinate), represent charging times during display CHA, during display VOL, represent cell voltage;
Short by power key, gear numeral can flash, and presses MODE key the most again and can change gear (1 at a slow speed, and 2 is middling speed, and 3 is quick);Gear can automatic Memory (this gear adjusted, start next time is still this gear) after adjusting;
Above " long press " refers to be 5 seconds~10 seconds, " short press " refer to 1 second~5 seconds.
Controller circuitry unit 40 includes at least one analog to digital conversion circuit, the sequence circuit that is connected with described analog to digital conversion circuit, multiple circuit of having the records of distance by the log for calculating mileage of being all connected with described sequence circuit, and described circuit of having the records of distance by the log is connected with described liquid crystal display circuit.
Multiple circuit of having the records of distance by the log, specifically include: the first circuit calculating single mileage, the second circuit calculating accumulative mileage, the tertiary circuit of calculating remaining mileage.
Display instrument 1 also has management charging times and/or the battery management module circuit 80 of charging voltage, and battery management module circuit 80 is connected with controller circuitry unit 40.
Battery management module circuit 80 uses Width funtion conversion chip, the DC voltage of 20~60V can transfer to 5V1A output, and export by USB interface.
Display instrument 1 also has the multiple gear circuit modules 90 for governing speed gear being connected with liquid crystal display circuit 50.
Multiple gear circuit modules 90 are connected with storage circuit 30.
Show that instrument 1 has and be installed on the multiple sensors being connected with controller circuitry unit 40 of electric vehicle body and/or for reporting the bluetooth module of vehicle body fault.When electric motor car breaks down, instrument can show the parts of fault, has brake fault, electrical fault, handle fault, controller failure etc. respectively.
