Abstract
A testing electricity pen for vehicle comprises a penholder and a lighting diode, the foreside of the penholder is a metal pole, the rearward of the metal pole is connected with a positive electrode of two-color diode LD1, a negative electrode of LD2 and a bulb L together, the positive electrode of LD2 is connected with the negative electrode of the LD1 which is connected with one end of a resistance R, the other end of the R is connected with the other end of the L and a crocodile clip through line conductor. The LD1, LD2, L and R are in the penholder in the middle of which three holes are set up, LD1 and LD2 are arranged to the side holes separately, the L is arranged to the middle hole, covers are set out of the holes. The utility model has the advantages of ingenious conception, simple structure, fewer stuff in use, lower cost, multiple function that the testing electricity pen is capable of not only detecting whether storage battery of the vehicle is charged or not, but also measuring qualitative the mount of quantity of electricity and polarity of electrode of the accumulator, the utility model is an appliance which is necessary to the car drivers and riding electric riders.
Description
Technical field
The utility model relates to test pencil, concrete is a kind of Test pencil for automobile.
Background technology
General general now test pencil function is very single, and basically can be measured to have in the loop exactly not to be had.Do not satisfied this function singleness of test pencil along with the science and technology development people, have and do not have outside the electricity such as measuring the loop, need also to know that the electric weight foot is not enough, if be accumulator and then can judge and how long to use, need also to know which is anodal, and which is a negative pole.Have this multi-functional test pencil, also do not have this product in the market.
Summary of the invention
The purpose of this utility model is can to measure the loop and have and do not have electricity in order to solve not have as yet in the market, again energy measurement electric weight sufficient test pencil and a kind of Test pencil for automobile is provided whether.
The technical scheme that adopts:
A kind of Test pencil for automobile, comprise the shaft of a writing brush, light emitting diode, the front end of the described shaft of a writing brush is a Metallic rod, the rear end of Metallic rod links to each other simultaneously with the positive pole of two-color diode LD1, the negative pole of LD2, the end of bulb L, the negative pole of dichromatic LED LD1 is connected with the positive pole of dichromatic LED LD2, and connects an end of resistance R, and the other end of resistance R is connected with the other end of bulb L and is connected with crocodile clip by lead simultaneously.Above-mentioned two-color diode LD1, LD2, bulb L, resistance R are arranged in the shaft of a writing brush, and shaft of a writing brush middle part does not have three apertures, and two dichromatic LEDs are installed in the both sides aperture respectively, aperture in the middle of bulb is installed in, the outside sealing cover of aperture.
Using method:
1. partly contact a utmost point of accumulator with shaft of a writing brush front end Metallic rod, clamp another utmost point of accumulator with crocodile clip.
2. bulb is very bright, illustrates that accumulator has electricity very sufficient, and near presenting red light emitting diode one end, electrode is negative for just near the electrode that presents green LED one end.
3. bulb brightness is medium, illustrates that accumulator has electricity but not really sufficient.
4. electric weight deficiency in the very dark explanation accumulator of bulb.
5. bulb does not work, and illustrates that accumulator is bad, internal break or year no charging for a long time.
The utility model is skillfully constructed, simple in structure, the consumption material is few, cheap, the diverse in function of test pencil, whether have electricity, can also measure the polarity of what and battery terminal of electric weight qualitatively if both can detect automobile storage battery, the utility model is the apparatus that automobilist and the people who rides electric motor car should need outfit.
