FIG. 1 is a schematic structural view for explaining a fuel sender for a vehicle of the present invention, and FIG. 2 is a schematic enlarged view for explaining a first plotter and a second plotter shown in FIG.

Referring to FIGS. 1 and 2, a fuel sender 100 for a vehicle according to an embodiment of the present invention can be used to prevent a safety accident due to a fuel amount measurement error. The vehicle fuel sender 100 includes a first floater 110 floated by the fuel 20 in the fuel tank 10 of the vehicle and a second floater 110 connected to the first floater 110 to detect the amount of the fuel 20 And a variable resistance plate 130 which is in contact with the floater arm 120 and is configured to change resistance according to a contact position of the floater arm 120 .

A first resistor 132 having an arc shape and in contact with the floater arm 120 on the variable resistance plate 130 and a second resistor 132 having an arc shape and disposed adjacent to the first resistor 132, (Not shown). One ends of the first and second resistors 132 and 134 are connected to a control unit 140 for measuring an electrical resistance from the first and second resistors 132 and 134 and calculating a fuel amount from the measured resistance ). However, since the configuration of the variable resistance plate 130 can be variously modified, the scope of the present invention is not limited by the configuration of the variable resistance plate 130. [

According to an embodiment of the present invention, a chamber 112 into which the fuel 20 flows may be provided in the first plotter 110, and on the upper surface of the chamber 112, And contact terminals 114 connected to the connection terminal 130 may be provided. The second floater 150 floated by the fuel 20 introduced into the chamber 112 may be disposed in the chamber 112. The contact terminals 114 may be formed of the floating 2 floater 150, as shown in FIG.

Meanwhile, the floater arm 120 may be in contact with the first and second resistors 132 and 134. For example, the floater arm 120 may include second contact terminals 122 that are in contact with the first and second resistors 132 and 134, respectively, and the contact terminals 114 and The second contact terminals 122 may be electrically connected to each other. As a result, an electrical closed circuit can be formed by the floating second floater 150 in the chamber 112, and the controller 140 can measure the resistance of the variable resistance plate 130.

For example, wires 124 connecting between the contact terminals 114 and the second contact terminals 122 may be disposed inside the plotter arm 120. The second floater 150 may be made of a relatively light material, for example, a plastic material, so that it can be floated by the fuel 20. On the upper surface of the second floater 150, A conductive coating (not shown) may be provided for electrical connection between the contact terminals 114.

The first floater 110 includes a fuel inlet 116 formed downward to allow the fuel 20 to flow into the chamber 112 and an air outlet 116 for discharging air inside the chamber 112. [ Lt; RTI ID = 0.0 > 118 < / RTI > Although the two fuel inlets 116 are provided, the number of the fuel inlets 116 may be variously changed, so that the scope of the present invention is not limited thereto.

According to an embodiment of the present invention, the upper portion of the chamber 112 may have a dome shape, and the second floater 150 may have a ball shape corresponding to the upper surface of the chamber 112. In this case, the conductive film may be entirely formed on the outer surface of the second floater 150, and the air outlet 118 may be disposed at an upper central portion of the chamber 112.

However, since the shape of the chamber 112 and the shape of the second floater 150 can be variously changed, the scope of the present invention is not limited by the shapes of the chamber 112 and the second floater 150 .

The controller 140 may measure the resistance change of the variable resistance plate 130 according to the change of the position of the first plotter 110 and calculate the amount of the fuel 20 according to the measured resistance value And the calculated flow rate can be informed to the driver through the instrument panel of the vehicle.

FIG. 3 is a schematic diagram for explaining a state in which the electrical connection by the second plotter shown in FIG. 1 is released.

According to an embodiment of the present invention, when the first plotter 110 and the floater arm 120 are not operated by the foreign matter fixing or the internal components of the fuel tank 10, if the fuel is consumed by the vehicle operation, The level of the fuel 20 is lowered so that the fuel 20 introduced into the chamber 112 can be discharged through the fuel inlet 116. [ In this case, as shown in FIG. 3, the second floater 150 can be moved downward, whereby the electrical connection between the contact terminals 114 can be released.

The controller 140 may provide an error message to the driver when the electrical connection between the contact terminals 114 is released. For example, the control unit 140 may display a message requesting inspection of the fuel sender 100 together with a malfunction signal through the vehicle instrument panel.

On the other hand, the electrical connection between the contact terminals 114 by the second floater 150 can be frequently released by the shaking of the vehicle generated during the operation of the vehicle. The control unit 140 may provide the error message when the electrical connection between the contact terminals 114 is maintained for a predetermined time, for example, several seconds to several tens of seconds.

According to the embodiments of the present invention as described above, the fuel sender 100 for a vehicle includes a first floater 110 floated by the fuel 20 in the fuel tank 10, a first floater 110 floated by the fuel 20 in the fuel tank 10, And is configured to change its resistance depending on a contact position of the floater arm 120 and a contact position between the floater arm 120 and the floater arm 120, And may include a variable resistance plate 130. Particularly, the first floater 110 is provided with a chamber 112 through which the fuel 20 flows, and on the upper surface of the chamber 112, a contact terminal electrically connected to the variable resistance plate 130, A second floater 150 floated by the fuel 20 introduced into the chamber 112 is disposed in the chamber 112 and the contact terminals 114 May be electrically connected to each other by the floating second floater 150. [

The electrical connection of the contact terminals 114 by the second floater 150 may be released when the fuel 20 is discharged from the chamber 112. That is, when the water level of the fuel 20 is consumed after the first floater 110 and the floater arm 120 are fixed by foreign substances or the like, the electrical connection by the second floater 150 Can be released.

When the electrical connection by the second floater 150 is released as described above, resistance measurement from the variable resistance plate 130 may be impossible, and it is easy to recognize that an abnormality has occurred in the vehicle fuel sender 100 . As a result, since the operation abnormality of the fuel sender 100 for the vehicle can be confirmed quickly and easily, a safety accident due to the fuel amount measurement error can be prevented sufficiently.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the following claims. It can be understood that.
