Abstract
The utility model relates to a displaying instrument, in particular to the integrated displaying instrument for electric vehicle belongs to the electric vehicle technical field. The displaying instrument comprises a function status displaying device arranged on the panel of the displaying instrument and a connecting jack. The utility model has the improvements that the connecting jack is provided inside with serial data wire interfaces which connected with controller corresponding port through external data wire, the serial data wire interfaces are connected to each function status displaying instrument via shift register. In this way, even more function status displaying device can be connected to the controller only by one data wire. The utility model is not only simple in the circuitry and convenient in connection, but also is helpful for decreasing the failure rate and contributes to electric energy conservation.
Description
Technical field
The utility model relates to a kind of display instrument, and especially a kind of structural development of battery-driven car display instrument belongs to the vehicle technology field.
Background technology
Along with the raising of people's living standard, the battery-driven car of Electrical Bicycle, Moped Scooter, electro-tricycle and so on has obtained popularizing rapidly.
Understand according to the applicant, above-mentioned existing battery-driven car substantially all is equipped with by diode displaying such as electric weight, speed, the display instrument of various state of a controls such as turns to.Yet light-emitting display device is connected with controller by circuit respectively in these existing display instruments, thereby forms the pattern of " line one lamp one signal ".Its shortcoming is, when show state more for a long time, the wiring complexity breaks down easily, and is unfavorable for economize on electricity.
The utility model content
The purpose of this utility model is: at the shortcoming that above prior art exists, propose that a kind of circuit is simple, the battery-driven car integrated form display instrument of easy-to-connect, thereby reduce fault rate, for the function of expansion display instrument lays the foundation.
In order to reach above purpose, battery-driven car integrated form display instrument of the present utility model comprises the functional status display device that is placed in the display instrument panel, and plug receptacle, its improvements are: contain in the described plug receptacle by the corresponding port bonded assembly with controller of external data line serial data line interface, described serial data line interface connects each functional status display device through shift register in respectively.
Like this,, also, not only simplify circuit as long as be connected with controller by a data lines even the functional status display device is many again, easy-to-connect, and help to reduce fault rate, and help saving electric energy.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the schematic circuit diagram of improvement part among Fig. 1.
The specific embodiment
Embodiment one
The battery-driven car integrated form display instrument of present embodiment as shown in Figure 1, functional statuses such as the electric weight that is mounted with on the display instrument panel of sub-elliptical, power-assisted, left-hand rotation, right-hand rotation, constant speed, self-charging show light-emitting diode, a cooresponding left side is housed combined switch, left brake lever, preceding indicator, loudspeaker, right brake lever, speed control crank plug receptacle on every side, and the serial data line interface.This serial data line interface, as shown in Figure 2, connects each functional status respectively through 74HC164 shift register U1 and shows light-emitting diode D1-D8 in display instrument by the corresponding port of data line external controller.The clock of serial data line interface (CLK), data (DAT) end connect the cooresponding input port of shift register U1 (referring to Fig. 2) respectively.
As seen from Figure 1, this display instrument be connected to the head light (QD) that contains steering indicating light, about change brake lever (ZB, YB), a left side combined switch (ZH), electronic horn (LB) etc., can finish and the communication of controller, battery (power supply).Many light-emitting diodes are indicated electric weight, power-assisted respectively, are turned to though this integrated form display instrument has, constant speed, from functions such as (instead) chargings, but only needing a data lines to be connected with controller gets final product, thoroughly change the pattern of " line one lamp one signal " in the past, easy-to-connect, display performance is stable.
In addition to the implementation, the utility model can have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on protection domain of the present utility model.
Claims (3)
1. battery-driven car integrated form display instrument, comprise the functional status display device that is placed in the display instrument panel, and plug receptacle, it is characterized in that: contain in the described plug receptacle by the corresponding port bonded assembly with controller of external data line serial data line interface, described serial data line interface connects each functional status display device through shift register in respectively.
2. according to the described battery-driven car integrated form of claim 1 display instrument, it is characterized in that: described functional status display device is a light-emitting diode.
3. according to the described battery-driven car integrated form of claim 2 display instrument, it is characterized in that: a left side is housed around described combined switch, left brake lever, preceding indicator, loudspeaker, right brake lever, speed control crank plug receptacle.
