Description

Fuel quantity character display

Technical field

This utility model is related to a kind of vehicle accessory, particularly to a kind of fuel quantity character display.

Background technology

At present, driver needs to know the oil mass in automotive oil tank, only can be implemented by the oil meter indicator on instrumental panel Observe, however, the quantity of prompting oil mass that only can be general on oil meter indicator is it is impossible to provide accurate numerical value, and oil meter refers to Show that instrument only has prompt facility, there is no warning function.If driver has forgotten observation oil meter indicator, then it is likely to work as postal Also will not timely go when oil in case is used up soon to refuel, thus affecting the normally travel of vehicle.

Content of the invention

In view of the shortcomings of the prior art, this utility model provide a kind of can be to the amount of fuel in different model fuel tank Examinations, and amount of fuel can be implemented warning reminding, the simple fuel oil of structure by numeral enforcement display and fuel oil when too low Oil mass character display.

For achieving the above object, this utility model provides a kind of following technical scheme: fuel quantity character display, its It is characterised by: include housing, located at the display screen on housing and the control device in housing, described control device bag Include power supply to be connected with power supply and be used for receiving the signal receiving module of fuel level sensor signal and signal reception mould in fuel tank Block electrical connection the signal amplification module that can filter clutter in signal and signal is implemented amplification are connected with signal amplification module Processor and memory module, the process by processor for the signal, convert analog signals into digital signal, and by this digital signal It is transferred to display screen.

Using technique scheme, the fuel level sensor in fuel tank by the width of fuel tank and height examinations, and Signal transmission will be gone back to signal receiving module, signal is transferred to signal amplification module, signal amplification module by signal receiving module By filter amplify after signal send processor to, processor to signal enforcement process transmit signals to memory module so as to Know the capacity of this fuel tank, in use, when the fuel oil in fuel tank starts to reduce, oil mass is subtracted by fuel level sensor again Signal is transferred to signal amplification module to signal receiving module, signal receiving module by few signal transmission, and signal amplification module will Filter the signal after amplifying and send processor to, processor after treatment, converts analog signals into digital signal and passes through to show Display screen implements display, makes driver can know the oil mass of liquid level of fuel oil in fuel tank at any time, thus preventing from refueling not in time when oil mass is too low And lead to the vehicle cannot normally travel.

This utility model is further arranged to: housing be provided with power supply indicator with power electric connection and with processor electricity The too low alarm lamp of oil level connecting.

Using technique scheme, whether being disposed to of power supply indicator points out this display in running order, And the too low alarm lamp of oil level is then to point out driver to add fuel oil the need of timely.

This utility model is further set to: control device also includes the alarm module electrically connecting respectively with processor And buzzer.

Using technique scheme, so setting can be reported to the police in the too low enforcement of oil mass, makes to have forgotten to observe driving of oil mass numeral The person's of sailing can be known is the need of interpolation fuel oil.

This utility model is further set to: housing includes the body with cavity volume and the bottom that can fasten with body Lid, described display screen, power supply indicator and the too low alarm lamp of oil level are respectively arranged on body；Described body and bottom Between connected by shackle member clamping, be provided with water-proof sealing strip between body and bottom.

Wherein, bottom is provided with the boss of ring-type towards one end of body, and the outer wall of this boss is fitted with the inwall of body, institute The shackle member stated includes the draw-in groove be adapted to located at the buckle in outer wall of boss and in inner body wall and with buckle, described Water-proof sealing strip is between boss and the inwall of body.

Using technique scheme, such setting structure is simple, is easy to assemble, and has water-proof function, prevents outside Medium enters into and in housing, control device is caused to damage.

Below in conjunction with the accompanying drawings this utility model is further described.

Brief description
