Description

Electrical Bicycle liquid crystal intelligent display screen

Technical field

The utility model relates to a kind of vehicle display device, particularly a kind of Electrical Bicycle liquid crystal intelligent display screen.

Background technology

The read-out of Electrical Bicycle display instrument employing now industry is an emerging industry, Electrical Bicycle display instrument content displayed is few in the market, have only electric weight to show, what also have has some basic displaying contents such as the speed of a motor vehicle, mileage, but datum error is bigger.

Summary of the invention

In view of the deficiency that prior art exists, the utility model provides a kind of Electrical Bicycle liquid crystal intelligent display screen.This liquid crystal intelligent display screen can not only accurately demonstrate electric weight, speed, the mileage of battery; Can also demonstrate the current motoring condition of Electrical Bicycle; The gear (one grade, second gear, third gear) of operation; Power-assisted, electronic, cruise etc.Particularly can also demonstrate Electrical Bicycle common faults point: electrical fault, handle fault, brake fault, controller failure etc. all can show by " liquid crystal intelligent display screen ".Thereby the cyclist by " liquid crystal intelligent display screen " to the motoring condition of bicycle and whether exist fault to come into plain view.

The technical scheme that the utility model is taked for achieving the above object is: a kind of Electrical Bicycle liquid crystal intelligent display screen, comprise the instrument carrier panel that is installed on the Electrical Bicycle, it is characterized in that: also comprise and LCDs circuit bonded assembly LCDs, being provided with the power line voltage figure in the described LCDs dynamically shows, speed meter graphic display and numeric display, the handle fault shows, electrical fault shows, controller failure shows, speed threshold shows, mileage shows and power-assisted, electronic, the running state of constant speed shows that LCDs is installed on the instrument carrier panel.

The beneficial effects of the utility model are: the cyclist by " liquid crystal intelligent display screen " to the motoring condition of bicycle and whether exist fault to come into plain view, especially fault shows, can make the maintainer know the guilty culprit of Electrical Bicycle at a glance, easy to maintenance, can reduce maintenance man-hours greatly, raise the efficiency.Both practical, reliable, save time again, laborsaving.

Description of drawings

Fig. 1 is a structural representation of the present utility model and as Figure of abstract.

Fig. 2 is schematic circuit diagram of the present utility model.

The specific embodiment

As shown in Figure 1, Electrical Bicycle liquid crystal intelligent display screen, comprise the instrument carrier panel 1 that is installed on the middle Plastic Parts of Electrical Bicycle handlebar, instrument carrier panel 1 comprises the wiring board that the LED lamp is installed, the plastic stent that has the LED lamp hole and color film, wiring board is fixed on the plastic stent, and the color film of glisten about one deck is printed on indication, headlight and brake indication is pasted on the plastic stent surface; LCDs 2 comprises wiring board and the LCDs that is welded with the read-out circuit, and LCDs welds in the circuit board, and the plastic stent of wiring board by screw and instrument carrier panel 1 fixes LCDs 2 is embedded on the instrument carrier panel 1.

Be provided with the power line voltage figure in the LCDs 2 and show that dynamically 2-1, speed meter graphic display and numeric display 2-2, handle fault show that 2-3, electrical fault show that 2-4, controller failure demonstration 25, speed threshold demonstration 2-6, mileage demonstration 2-7 and power-assisted, running state electronic, constant speed show 2-8.

As shown in Figure 2, the LCDs circuit comprises: microprocessor (MPU) U1, memory device U2, LCDs 2 and peripheral circuit, peripheral circuit comprises: resistance R 8, R9, R10, R12, R14, capacitor C 7, C8, C12, its circuit is connected to: resistance R 8, R9, R10, R12, R14 one termination power positive pole, the other end respectively with the CLK of microprocessor (MPU) U1, SCL, SDA, VLCD, the RES pin connects, capacitor C 7, C12 one termination power positive pole, the other end ground connection (GND) of capacitor C 7, the other end of capacitor C 12 connects the RES pin of microprocessor (MPU) U1 and an end of resistance R 13 respectively, the other end of resistance R 13 is by capacitor C 8 ground connection GND, the 1-24 pin of described LCDs 2 meets the SEG5-SEG12 of microprocessor (MPU) U1 respectively, COM3-COM0, the SEG24-SEG13 pin, 1 of memory device U2,4 pin meet the SCL of microprocessor (MPU) unit U1 respectively, the SDA pin, the 2 pin ground connection (GND) of memory device U2,5 pin power connection positive poles.
