Abstract

The utility model discloses a car information display which comprises a panel, buttons, a liquid crystal display (LCD) display screen, a light guide plate, a connector, a light reflective bracket, a printed circuit board (PCB) board and a shell. The LCD display is fixed on the PCB board through tin soldering, and is in electrical connection with the PCB board through the connector, the light reflective bracket provided with the guide plate is connected with the PCB board in clamped mode through unilateral cards, the PCB board is fixed on the shell through screws, the panel is connected with the shell in clamped mode through unilateral cards, and the panel is provided with the buttons which achieve switchover of time adjustment and an instantaneous fuel consumption display unit. The car information display can concentrate current time, temperature outside a car and instantaneous fuel consumption display to be displayed on the same information display, reduces occupied space of display units, and also can enable a driver to check all relevant information intensively.

Description

A kind of automobile information telltale
Technical field
The utility model relates to car electrics, is specifically related to a kind of automobile information telltale.
Background technology
At present; Many information display units are arranged on the panel of automobile cab; Such as time showing, outside front truck various reflections such as temperature, the current oil consumption information of environment and current condition of the vehicle of driving, these information show that on display unit separately making has many display units on the panel of automobile cab; So there is the panel finite space that had both taken automobile cab, makes chaufeur can not the concentrated area check the defective of all relevant informations again.
The utility model content
The purpose of the utility model provides a kind of automobile information telltale, and this automobile information telltale can show centralized displaying with time, the outer temperature of car and instantaneous oil consumption, reduces taking up room of display unit.
The described a kind of automobile information telltale of the utility model; Comprise panel, button, LCD display, LGP, connector, reflective carriage, pcb board and housing; Said LCD display is fixed on the pcb board through soldering, and through connector and pcb board electrical communication, on the reflective carriage LGP is housed; Reflective carriage is connected on the pcb board through monolateral; In housing, panel is monolateral to be connected on the housing pcb board through screw retention, and panel is provided with the button that the realization time is regulated and the instantaneous oil consumption unit of display is switched.
Form by power supply voltage-stabilizing system and signal handling equipment on the said pcb board;
The power supply voltage-stabilizing system: the backlight to signal handling equipment and LCD display provides burning voltage;
Signal handling equipment: comprise LCD driving, key scan processing, real-time clock calculating, instantaneous oil consumption signal acquisition process, the outer temperature acquisition processing of car and LCD regulating control backlight unit.
The utility model compared with prior art has the following advantages: current time, the outer temperature of car and instantaneous oil consumption are shown to focus in the information display show; Reduced taking up room of display unit, can make the chaufeur concentrated area view all relevant informations again.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the exploded drawings of the utility model;
Fig. 3 is the systematic schematic diagram of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Automobile information telltale as depicted in figs. 1 and 2 comprises panel 1, button 2, eyeglass 3, LCD display 4, LGP 5, connector 6, reflective carriage 7, pcb board 8 and housing 9.LCD display 4 is fixed on the pcb board 8 through soldering, realizes the electrical communication of LCD display 4 and pcb board 8 through connector 6.Six LED lamp are arranged on the pcb board 8, and this six LED lamp is as the backlight of LCD display 4, realizes the homogeneity of printing opacity through LGP 5, and LGP 5 is contained on the reflective carriage 7, and reflective carriage 7 is connected on the pcb board through two monolateral cards.On housing 9, panel 1 is connected on the housing 9 through six monolateral cards pcb board 8 through two screw retention, and there is eyeglass 3 centre.
Panel 1 is provided with the button 2 that the realization time is regulated and the instantaneous oil consumption unit of display is switched.
Time is regulated button: can be according to the customer requirement control duration;
Instantaneous oil consumption unit of display switching key: can between 100KM/L and two oil consumption units of L/100KM, switch arbitrarily according to user's use habit.
Pcb board 8 is made up of power supply voltage-stabilizing system and signal handling equipment;
The power supply voltage-stabilizing system: to the backlight of signal handling equipment and LCD display the burning voltage of 5V and 12V is provided, adopts the automotive grade NCV4274 power module of ON to supply with as the power supply of this module, the quiescent current of keeping clock circuit timework is less than 3mA.
Signal handling equipment: comprise the driving of the LCD tip of the brushstyle of a writing or painting, key scan processing, real-time clock calculating, instantaneous oil consumption signal acquisition process, the outer temperature acquisition processing of car and LCD regulating control backlight; The microprocessor that adopts Freescale automotive grade band LCD to drive; Accomplish incorporate LCD driving, key scan processing, real-time clock calculating, instantaneous oil consumption signal acquisition process, the outer temperature acquisition processing of car and LCD regulating control backlight; Improve the reliability of module, reduced the power consumption of module simultaneously.
