Abstract
The utility model belongs to a modified machine oil level measuring display device, particularly an electronic machine oil level measuring display device for visually displaying the machine oil level on the automobile or the tractor. The device is composed of a switch K, a current-limiting resistor R, a light emitting diode, two resistors R1, R2, a capacitance C, a unijunction transistor BG, a buzzer and a sensor. The machine oil level changing signal on the sensor changes into an electrical signal which is introduced into the electronic circuit and makes the light emitting diode shine; when the engine oil liquid level reduces to danger position, the buzzer sends alarm sound, and a red light emitting diode sends light. The device resists vibration, and has long lifetime, simple structure, reliable operation, high anti-interference capability and strong universal performance. The device is also easy in use and maintain, and is suitable for various automobiles and tractors.
Description
The utility model is to measure display device in order to the electronic type engine oil level of demonstration engine oil level directly perceived on a kind of improved engine oil level measurement display device, particularly automobile, tractor and other internal combustion engines.
Automobile, tractor and other internal combustion engines all lubricate by machine oil, play a part cooling medium again simultaneously, thereby once machine oil is very few, will be formed at friction because of lacking machine oil, cause engine scuffing and heating, and then damage engine.Measuring engine oil level at present on automobile, the tractor all is to adopt steel plate ruler type dipstick, by manual operation, this not only brings many inconvenience to driver's operation, and read untrue, not directly perceived, especially when running car, can not measure engine oil level, bring a lot of inconvenience to driving.
The purpose of this utility model provides the engine oil level measurement display device that a kind of electronic devices and components constitute, be applied on the various internal combustion engine, particularly be applied on automobile, the tractor, vibration resistance, long-life, simple in structure, reliable operation, engine oil level no matter shows daytime or night is all clear, bright, accurately, when engine oil level is in danger position, can send sound and light alarm.
The utility model is achieved in that establishing indicator has three branch roads, and three branch roads are connected with its corresponding contact block, and ball float, connecting rod and slide block connect together.When engine oil level changed, ball float drove slide block and makes corresponding contact rectilinear motion, and the contact block that contact is corresponding makes positive source constitute a closed-loop path through indicator to power cathode, the lumination of light emitting diode of corresponding branch road; Luminous according to the different branch light emitting diode, the just height of engine oil level as can be known.This covering device is installed on the automobile height of engine oil level when just making the driver know running car easily.The buzzer and the red light emitting diodes that have also had the warning effect simultaneously on this device make the driver can know clearly that machine oil has dropped to danger position, in time remind him to refuel.This device can be designed to the engine oil level measurement mechanism that matches with different model automobile and internal combustion engine, thereby highly versatile, use easy to maintenance owing to adopt electronic component structure, thereby intuitive display, clear, long service life.
Describe in further detail below in conjunction with accompanying drawing:
Figure (1) is a fundamental diagram of the present utility model.
Figure (2) is the Pareto diagram of light emitting diode on dial plate.
Electronic type engine oil level of the present utility model is measured display device and is formed (see figure 1) by indicator and sensor two parts, wherein indicator part is installed in the watchcase of gauge outfit (11) of accompanying drawing 2, and with lead gauge outfit (11) and sensor (15) is interconnected (see figure 2).
With reference to Fig. 1: by the current-limiting resistance R among the figure, light emitting diode (2), D, resistance R 1, R2, capacitor C, K switch, unijunction transistor BG and buzzer (3) constitute indicator circuit, this indicator circuit has a, b, three branch roads of c, wherein arbitrary branch road in a, the b branch road is made up of shared current-limiting resistance R, light emitting diode (2), C props up route resistance R 1, R2, and capacitor C, unijunction transistor BG and buzzer are formed.Every branch road a, b, the c contact block corresponding with it is connected.Sensor among the figure comprises contact block (4), slide block (5), connecting rod (6) and ball float (7).Fastener among the figure (8), machine oil pond (9) and engine oil level (10) are in order to describe the optional feature of the utility model embodiment.
As seen from Figure 1: whole sensor is fixed on the engine by securing member (8), ball float (7) is subjected to the control of liquid level (10) lifting of machine oil pond (9), drivening rod (6), connecting rod (6) drives slide block (5) and make the contact rectilinear motion on contact block (4), thereby makes the electronic circuit of this device constitute closed circuit.When in slide block (5) and a, b, the c contact block (4) during arbitrary the contact, just constituted the wherein closed-loop path of a corresponding branch road of this electronic circuit.When slide block (5) and adjacent two contact blocks (4) when contacting, can constitute the closed-loop path of corresponding two adjacent legs.Like this, the rarest lumination of light emitting diode of each connection has two adjacent lumination of light emitting diode at most, thereby reaches the purpose of measuring engine oil level in the display machines oil sump.
When K switch is closed, when slide block (5) slides to a contact block (4), just connect a branch road, this moment, electric current flow through resistance R from positive source (1); Light emitting diode makes light emitting diode (2) luminous to power cathode, thereby can see numeral " 1 " on the scale mark (14) of Fig. 2 surface (12), and this numeral engine oil level is in super oil level.In like manner, when slide block (5) slides to b contact block (4), make lumination of light emitting diode, thereby see numeral " 1/2 " on the scale mark (14) of Fig. 2 surface (12), the expression engine oil level drops to the normal position.
When K switch is closed, when slide block (5) slides to c contact block (4), just connected the C branch road, this moment, electric current flow through resistance R 1, R2, capacitor C, unijunction transistor BG, light emitting diode D and buzzer (3) to power cathode from positive source (1), because discharging and recharging of capacitor C, make this branch road flow through oscillating current, thereby red light emitting diodes D is flashed, buzzer (3) sends intermittently sound, thereby on the scale mark (14) on figure (12) surface (2), see digital " 0 ", the expression engine oil level drops to dangerous values, plays the sound and light alarm effect.
Electronic type engine oil level of the present utility model is measured display device, can select the contact block (4) of varying number according to actual needs, select the number of the light emitting diode of corresponding display device (2) again for use, change the resistance of resistance R, thereby reach the needed degree of accuracy requirement of display machines fluid.Also should change the scale mark (14) of surface (12) this moment.
Present embodiment can adopt the light emitting diode of different colours so that reach the purpose of demonstration engine oil level directly perceived.The arrangement of light emitting diode on dial plate can be adopted circular arc or linear, can be horizontally-arranged or vertical setting of types.
