Abstract
The utility model provides a float type vehicle fuel measuring device, comprises an electronic display circuit, a power and furthers a float type distance measurement structure which is composed of a floating plate, a reflecting convex mirror, a distributed-emission diode, a sensor photo detector and an optical signal processing. The utility model has the advantages of simple structure, high accuracy degree and sensibility, and low error, while the floating plate is placed on the oil surface of the vehicle oil box and takes up most of the oil surface, which protects the reflecting convex mirror against the effect of the vehicle running state and wave, thereby having a good earthquake resistance and an accurate meter.
Description
Technical field the utility model relates to a kind of vehicle oil measurement device, especially has the vehicle oil measurement device of float type range observation structure.
Background technology vehicle oil mass display device is a kind of being installed on the vehicle, can dynamically show the device of oil mass in the oil tank of vehicle.Vehicle oil mass display device commonly used generally partly is made up of liquid level sensor, testing circuit, amplifier, A/D converter, single-chip microcomputer, electronics display circuit, warning circuit, button inputting circuits, detection of power loss and holding circuit etc., wherein, liquid level sensor, testing circuit is connected between sensor and the amplifier, amplifying signal send single-chip microcomputer after the A/D converter conversion, single-chip microcomputer software program for execution, single-chip microcomputer are connected with electronics display circuit, warning circuit, button inputting circuits, detection of power loss and holding circuit respectively.This structure is too complicated on the one hand, and cost is higher; Dynamic demonstration to oil mass is inaccurate on the other hand, and particularly vehicle can't accurately show the oil mass in the fuel tank in the process of moving.
Chinese patent CN2554613 number disclosed " vehicle-mounted fuel oil digital display gauge " patent (application number: CN02275915.8), a piezoelectric ceramic ultrasound self-focusing fuel liquid level sensing device is set on vehicle-mounted fuel oil casing top, in this device, be provided with a piezoelectric ceramics right cylinder, and metal shell stickup is set on its outer surface as positive level, offer a conical ultrasound wave self-trapped hole in these cylindrical bottom side central authorities, and a metal shell is set sticks on its inside surface as negative level, be provided with the gap between the metal shell on its inside and outside surface; And a microcomputer electric electronic circuit and digital automatic display are set on the bridge instrumentation dish of its car, and being connected to become a kind of vehicle-mounted fuel oil digital display gauge accordingly by cable and wire, it has high-performance, pinpoint accuracy, high sensitivity, error is little, and reaction velocity is fast, good reliability, vibration resistance is strong, and zero point drift is little, good stability, low beneficial effect and the characteristics of waiting of cost can be widely used in the digital display metering of fuel oil in all kinds of motor vehicles top tanks.The weak point of this patent is: since vehicle in the process of moving the pasta in the fuel tank be in the continuous wave process, so the detected liquid level of ultrasound wave also fluctuates.
The purpose of this utility model is exactly that a kind of float type vehicle oil measurement device simple in structure will be provided, and makes its interior oil mass of measuring vehicle fuel tank exactly, brings convenience to vehicle drive.
The utility model content in order to achieve the above object, the float type vehicle oil measurement device that the utility model provides is except comprising parts such as electronics display circuit, power supply, also comprise float type range observation structure: float type range observation structure is made up of kickboard, reflection convex lens, emission optical diode, responsive photodetector, light signal Processing Structure, wherein, kickboard is placed on the interior pasta of oil tank of vehicle, and occupies the overwhelming majority of pasta; The reflection convex lens is fixed on center above the kickboard, is used to reflect the emission light that optical diode sent; Responsive photodetector is placed in the top in the oil tank of vehicle, is used to receive the reflection light signal that convex lens reflected.When the utility model uses, emission optical diode emission light signal is received by responsive photodetector after the reflection of reflection convex lens, after the light signal Processing Structure, can measure the move distance of light signal, thereby obtain fuel head and oil mass in the oil tank of vehicle, and the electronics display circuit is presented at oil mass on the pilothouse.
The float type vehicle oil measurement device that the utility model provides has a significant effect: float type range observation structure is made up of kickboard, reflection convex lens, emission optical diode, responsive photodetector, light signal Processing Structure, simple in structure, degree of accuracy and sensitivity are all high, and error is also little; Kickboard is placed on the interior pasta of oil tank of vehicle, and occupies the overwhelming majority of pasta, makes the reflection convex lens be subjected to the influence of vehicle running state hardly and produce fluctuation, good anti-vibration, and it is very accurate to measure.
Description of drawings the utility model will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:
Accompanying drawing is represented synoptic diagram of the present utility model.
Structure shown in the drawings comprises: electronics display circuit (1), responsive photodetector (2), emission optical diode (3), reflection convex lens (4), kickboard (5), oil mass (6), fuel tank (7).
Float type vehicle oil mass (6) measurement mechanism that embodiment the utility model provides is except comprising parts such as electronics display circuit (1), power supply, also comprise float type range observation structure: float type range observation structure is made up of kickboard (5), reflection convex lens (4), emission optical diode (3), responsive photodetector (2), light signal Processing Structure, wherein, kickboard (5) is placed on the interior pasta of oil tank of vehicle (7), and occupies the overwhelming majority of pasta; Reflection convex lens (4) is fixed on center above the kickboard (5), is used for the light that reflection emission optical diode (3) is sent; Responsive photodetector (2) is placed in the top in the oil tank of vehicle (7), is used for receiving the light signal that reflection convex lens (4) is reflected.When the utility model uses, emission optical diode (3) emission light signal is received by responsive photodetector (2) after reflection convex lens (4) reflection, after the light signal Processing Structure, can measure the move distance of light signal, thereby obtain fuel head and oil mass (6) in the oil tank of vehicle (7), and electronics display circuit (1) is presented at oil mass (6) on the pilothouse.
The utility model protection domain relates to all changes form recited above.
