The circuit diagram for the car battery power measuring device 3 is as shown in Figure 5, which is to make an electronic circuit to measure the voltage of the battery and by means of LED indicator lamps to directly and respectively represent battery power strength with classification in "GOOD", "MID" and "LOW". The principle applied is to make use the properties of the transistance of the transistor action to respectively control switching on/off of the LED indicator lamps.
For better understanding, hereinafter is a description for measuring a 12V car battery. As shown in the circuit diagram, 01, 02, 03 represent respective transistors of three different grades of bias working voltage; A. Indicator lamp LOW (red indicator lamp, LEDI) is designed to turn on at voltage over IV, it forms an exclusive loop; when battery voltage is exceptional low, Q1, 02, 03 are not on, the red indicator lamp LOW is turned on and the MID and GOOD indicator lamps are off; B. If battery power is over SV, 01 is on and the indicator lamp LOW is off; 02 is on and reaches saturated condition to turn an the indicator lamp MID (green indicator lamp, LED2); 03 is designed to turn on when power is over IOV, and therefore, during voltage between a-10V 03 is not on and the indicator lamp GOOD (green indicator lamp, LED3) is also not on; 9 C. If battery power is over 1OV, 01, 02, and C23 are all turned on, since (21 is on the red indicator lamp LOW is short-cut and off, and therefore, indicator lampr. MID and GOOD are turned on.
only green Therefore, according to the lighting condition of the indicator lamps, the battery power measured can be thus determined as follows:
normal Red lamp LOW: I-8V -> power supply is too low to make _start, battery should be replaced or recharged; Green lamp MID: E-10V => power supply below condition, battery should be recharged; Green lamp GOOD: 10-12V => power 5 upply is all car facilities can be properly operated.
According to car electric specifications, all the electric appliances of the car can be operated at time battery reduces its 1/3 of its power, in case battery power reduced over 1/3 the batter)i should be recharged immediately. By means of the above described practicable and simpletooperate car battery power measuring device, the user can easily know the actual condition of the battery power through the indication of the LED lamps.
According to the above description, the present invention is used for measuring car tire pressure, tire (outer tire) tread depth, and car battery power, i.e.
shown in Figure 2, when to press the pressure-measuring 21 on the air valve (not shown in the drawing) the inner air exhausts to act an the horn plug 23 according to its pressure, and to consequently push the compressed spring 24 normal, as head and also to push the scale 25 outward, and from the graduation of the scale that protrudes, the tire pressure is thus indicated ( if to move away the present invention from the air valve, the compressed spring 24 and the horn plug 23 return to original position, but the scale remains at its protruding position unless otherwise pushed by outer force, and the protruding condition helps the user to examine the graduation showed). According to the present invention, the pressure-measuring element is also applicable for measuring tire tread depth, i.e. to draw up the scale 20 from its rear end (as shown in Figure 2, but the horn plug 23 and the compressed spring 24 are remained inside and not drawn up) and insert it into the dent 41 of the tread of the tire 4 and press down the housing 1 of the present 15 invention letting the bottom of the housing 1 be smoothly attached to the outer surface of the tire (as shown in Figure 4), then move away the present invention from the tire and examine the protruding of the graduation of the scale for the depth of the tread.
When to measure the battery power, it is to directly insert the pressuremeasuring metal head 21 and the metal strap 32 into the cutlet of the car battery electrode (cigar lighter an the car dash board), the metal head 21 and the metal strap 32 are then respectively in contact with the positive pole and the negative pole of the battery to transmit the battery power to the battery power measuring device 3, and then according to the indication tery power is thus lamps lightened, the strength of the batt 1 determined.
According to the above described, the present invention is indeed to provide a new, improved, and practicable measuring device. However, the above description is for full understanding of the present invention, anyone who knows the art makes any modification or variation of application according to the spirit of the present invention should be included into the category of the present application.
