Description

The motorcycle oil amount indicator

The utility model relates to the oil quantity indicator of a kind of oil quantity indicator, particularly a kind of motorcycle.

Existing motorcycle generally is to use fuel oil to obtain power, in order to allow the rider can understand oil mass in the fuel tank, one oil mass pick-up unit all is set in fuel tank usually, this oil mass is examined side device and is connected to the oil mass indicating gauge of instrument panel, and the oil mass pick-up unit is nested in a ball float on one connecting rod, the connecting rod other end is established a probe and is bonded on the side of a floating seat again, this side is provided with the resistor chain 1 of vertical, as shown in Figure 1, resistor chain 1 upper and lower side is respectively with electric wire 11,12 are connected to a power supply, the centre then is a ground wire 13, and establish resistance 16 corresponding to full oil mass 14 and 15 of oil masses of preparation with 12 different voltage numbers at two, when ball float along with fuel tank in oil mass and lifting, then move with regard to drivening rod thereupon, and make the probe of link end make synchronization lifting at resistance 1, because the resistance ratio of each section resistance 16 is neither identical, therefore probe will elicite different resistance ratios, and exportable different electric current is to two groups of mutually perpendicular coil places, oil mass indicating gauge below, make and produce synthetic magnetic force in two groups of coils, and can drive pen travel on the oil mass indicating gauge by magnetic force, indicate present Fuel Oil Remaining.

Above-mentioned oil quantity indicator is used on the motorcycle always, this structure no doubt can reach the purpose of indication oil mass, but because pointer is a mechanical type manner of execution, therefore its error is bigger, simultaneously, because the fuel tank of each tame manufacturer differs because of design appearance, but resistor chain but all is similarly vertical type and arranges, cause becoming a preferable cooperation, so that easily produce error, and can not be correct indicate remaining oil mass.

Primary and foremost purpose of the present utility model, be to provide a kind of motorcycle oil amount indicator that utilizes voltage ratio than drive circuit oil mass indicating gauge, mat is established a controller provides a fixed voltage to resistor chain, and the number that can utilize oil mass is obtained a certain magnitude of voltage and is back to controller, drive in the corresponding LED group of oil mass indicating gauge, to show accurate oil mass through the voltage comparison loop again.

For the utility model that achieves the above object is taked following measure:

Motorcycle oil amount indicator of the present utility model, the main oil mass indicating gauge of a LED group of on instrument panel, establishing, one controller thereunder is set, this controller also links to power supply and the resistor chain of floating seat, wherein Dian negative pole be connected to resistor chain in the middle of the place make and form a test side, detect a magnitude of voltage by the number of oil mass and be back to a signal processing circuit in the controller, through dividing potential drop, transport to a comparator circuit after the voltage stabilizing again, with predefined magnitude of voltage in it relatively after, output signal to one drive circuit again, the diode (LED) that drives oil mass indicating gauge corresponding number is shinny.

Conjunction with figs. and embodiment are described as follows the utility model:

Description of drawings:

Fig. 1: the synoptic diagram of commonly using indicator electricity group row.

Fig. 2: the utility model indicator electricity group row's synoptic diagram.

Fig. 3: circuit box circle of the present utility model.

The utility model mainly is an oil mass indicating gauge of establishing a LED group at the instrument panel place of headstock, and below connect the controller of establishing a line, controller also is wired to the resistor chain that floating seat is located, the then the same power supply place that is wired to of floating seat with located by prior art, this is so that general electronics wiring technology is not expression among the figure, at first see also Fig. 2, because this case is the number of indicating oil mass with the LED group, just must pick up the size that detects voltage makes comparisons with driven for emitting lights diode (LED) group for this reason, and can't use traditional resistance comparison circuit to finish, therefore resistor chain 2 just must be done a change, be about to ground wire 21 and do an exchange with electric wire 22 positions of lower end, make positive supply connect the electric wire 23 of end, negative supply is then received ground wire 21, and seeing also Fig. 3, controller is by mu balanced circuit, oscillatory circuit, driving circuit, comparator circuit and signal processing circuit constitute, and wherein power input is communicated to resistor chain 2 and other circuit again through behind the mu balanced circuit earlier.

The utility model becomes stable voltage for use the current conversion of input by mu balanced circuit, electric wire 22 when resistor chain 2 test port, obtain after a certain magnitude of voltage by the number of oil mass, this magnitude of voltage just is back to signal processing circuit in the controller via electric wire 22, carry out dividing potential drop by signal processing circuit, voltage stabilizing is handled, make comparisons with pre-set voltage then, utilize ten LED groups in the present embodiment, then also be redefined for ten different magnitudes of voltage in the comparator circuit, make each magnitude of voltage corresponding with the number of LED group, then work as in the magnitude of voltage that the magnitude of voltage that returns is relatively down full oil mass, transport to driving circuit again and do to drive indication, and ten diodes on the oil mass indicating gauge LED of the place group are all lighted, mode and indicate remaining oil mass in the fuel tank according to this, the notice that while can be reminded the rider when preparing oil mass in order to reduce to when oil mass residual in the fuel tank, therefore when detected magnitude of voltage through relatively when preparing the magnitude of voltage of oil mass, comparator circuit can output signal to oscillatory circuit, transport to driving circuit again, the LED group is luminous to be continuous blink states and order about, certainly also can be via the hummer sounding, use and improve the vigilance oiling quickly that is driving.

The action of indication oil mass device of the present utility model, owing to be to finish automatically all with electronic circuit, therefore error can not take place fully, and can realize oil mass indication accurately, and when the oil mass in the fuel tank is reduced to fuel allowance, more can remind the rider to note driving the phenomenon of not having oil midway by caution to prevent.

Claims (1)
