Abstract
The utility model relates to a multifunctional liquid crystal display instrument for an electric vehicle, comprising an instrument dial, a liquid crystal screen arranged on the instrument dial and a circuit, wherein the circuit comprises a signal detection circuit, a signal feedback circuit and an information acquisition and processing control system; one end of the signal detection circuit is connected with a direct-current brushless controller integrated with a plurality of fault detection modules, and the other end of the signal detection circuit is connected with the information acquisition and processing control system; and the information acquisition and processing control system is connected with the liquid crystal screen by the signal feedback circuit. In the multifunctional liquid crystal display instrument, the information acquisition and processing control system and a liquid crystal display technology are adopted, the parameters of a motor, a rotary handle, temperature and fault conditions and the like can be displayed by the liquid crystal screen, the accuracy is high, the display of mechanical errors of the instrument can be avoided, the stability and the reliability are achieved, the dial body is thinner, the weight is light, the color development of the screen is clear and the appearance is attractive.
Description
Technical field
The utility model relates to a kind of multi-functional liquid crystal display instrument, particularly a kind of multi-functional liquid crystal display instrument of electric vehicle that the various signal parameters of battery-driven car are shown.
Background technology
Battery-driven car is more and more universal now, becomes the walking-replacing tool of new generation of people's trip.And existing battery-driven car instrument is very simple and crude, except parameters such as speed per hour, electric weight, left and right sides steering indicating light and headlight show, does not just have other can understand the human-computer interaction interface of battery-driven car more information for the driver.This accuracy of an instrument is relatively low, and reliability is also poor, does not have professional testing tool, and it can only be to shift maintenance store maintenance onto that battery-driven car is out of order, and dial plate has been seen for a long time and easily caused driver's visual fatigue.
Summary of the invention
The utility model is exactly that a kind of multi-functional liquid crystal display instrument of electric vehicle that shows more battery-driven car signal parameters is provided for the deficiency that addresses the above problem.
The technical solution of the utility model is as follows:
The multi-functional liquid crystal display instrument of a kind of electric vehicle, comprise set liquid crystal display and circuit on dial plate, the dial plate, it is characterized in that: described circuit comprises signal deteching circuit, signal feedback circuit and information acquisition process control system, signal deteching circuit one end links to each other with the brush DC controller of having integrated some fault detection module, the other end links to each other with the information acquisition process control system, and the information acquisition process control system links to each other with liquid crystal display by signal feedback circuit.
Described fault detection module comprises motor detection module, temperature detecting module, handle detection module, brush DC controller selftest module and safety system module, links to each other with brush DC controller main control board by electric wire or chip integration mode with upper module.
The beneficial effects of the utility model are as follows:
The utility model adopts information acquisition process control system and lcd technology, parameters such as motor, handle, temperature and failure condition can be crossed liquid crystal display directly to be shown, the precision height, instrument mechanicalness mistake can not occur shows, reliable and stable, and the table body is thinner, in light weight, the screen colour developing is clear, good looking appearance.
Description of drawings
Fig. 1 is the circuit diagram of the multi-functional liquid crystal display instrument of the utility model electric vehicle;
Fig. 2 is the meter information feedback engineering mode reference diagram of the multi-functional liquid crystal display instrument of the utility model electric vehicle.
The specific embodiment
Consult Fig. 1, the multi-functional liquid crystal display instrument of a kind of electric vehicle, comprise set liquid crystal display 5 and circuit on dial plate, the dial plate, described circuit comprises signal deteching circuit 2, signal feedback circuit 4 and information acquisition process control system 3, signal deteching circuit 2 one ends link to each other with the brush DC controller 1 of having integrated some fault detection module, the other end links to each other with information acquisition process control system 3, and information acquisition process control system 3 links to each other with liquid crystal display 5 by signal feedback circuit 4; Described fault detection module comprises motor detection module 11, temperature detecting module 12, handle detection module 13, brush DC controller selftest module 14 and safety system module 15, links to each other with brush DC controller 1 main control board by electric wire or chip integration mode with upper module.
Motor detection module 11, temperature detecting module 12, handle detection module 13, brush DC controller selftest module 14 and safety system module 15 follow the tracks of the parameter of battery-driven car of detection from brush DC controller 1 governor circuit, testing result is read by the signal deteching circuit 2 that brush DC controller 1 links to each other, signal deteching circuit 2 sends various parameters to information acquisition process control system 3, and information acquisition process control system 3 presents by the liquid crystal display that is contained on the headstock instrument by signal feedback circuit 4 after information processing.
When detecting electric weight that brush DC controller 1 flows to motor and reach certain value as safety system module 15, signal is passed to information acquisition process control system 3 from level to level, information acquisition process control system 3 is handled and is converted into the speed of a motor vehicle, Deng reaching when limiting the speed of a motor vehicle, notice that on liquid crystal display the hypervelocity hurdle can flash the redlight, thereby remind the driver to note the speed of a motor vehicle.
The above only is the specific embodiment of the present utility model; should be understood that; for those skilled in the art; on brush DC controller 1 governor circuit; all right integrated other detection modules; do not break away under the prerequisite of the utility model principle at these, these improvement also should be considered as protection domain of the present utility model.
