In order to solve Problems existing in the teaching of existing demonstrator, the purpose of this utility model is to provide a kind of for automobile current generator electric circuit teaching teaching case, and its volume is little, easily movement, and has good teaching efficiency.
The technical scheme that the utility model adopts is:
A kind of for automobile current generator electric circuit teaching teaching case, comprise teaching casing, automobile ignition switch, fuse, motor, alternator, rectifier and accumulator is equiped with in described teaching casing, described motor band motor alternator rotates generating, and described alternator connects accumulator by rectifier and is charge in batteries.
As the further improvement of technique scheme, in described casing, be provided with the electric machine speed regulation controller for controlling motor speed.Regulated the rotating speed of motor by electric machine speed regulation controller, thus control the rotating speed of alternator, alternator generation amount raises with rotating speed and increases.
As the further improvement of technique scheme, charging alarm lamp is provided with in described casing, described automobile ignition switch, fuse and charging alarm lamp are connected in the discharge circuit of accumulator, and further, described alternator is connected to charging alarm lamp two ends after rectification.In accumulator normal charging process, the level at charging alarm lamp two ends is equal, and charging alarm lamp can not be bright; And when accumulator occurs that charging is abnormal, charging alarm lamp is lighted, remind car owner's circuit to occur abnormal, answer parking checking reason.
As the further improvement of technique scheme, the full bridge rectifier that described rectifier is made up of eight diodes, wherein four diode forward conductings, the conducting of other four diode negative senses, described accumulator to negative sense conducting diode between be provided with capacitor.Capacitor plays and intercepts galvanic effect.
The beneficial effects of the utility model are:
Teaching case of the present utility model has that cost is low, volume is little, lightweight advantage, is easy to carry, and can be carried into the place such as laboratory or classroom and use, the circuit of the case of this teaching simultaneously not easily generates heat, short circuit, easily repairs, safeguards, can easily for teaching.Adopt teaching case of the present utility model to impart knowledge to students, student can the very clear circuit seeing automobile current generator circuit, more easily understands its principle of work, and by allowing student start connection line, make it understand line alignment, teaching efficiency is remarkable.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is automobile current generator circuit theory diagrams of the present utility model.
Embodiment
With reference to Fig. 1, the preferred embodiment that the utility model provides, a kind of for automobile current generator electric circuit teaching teaching case, comprise the casing 1 of plastics or metal or paperboard, in described casing 1, be equiped with automobile ignition switch S1, fuse F, motor (not shown), alternator G1, rectifier, charging alarm lamp L and accumulator E.
Described motor band motor alternator G1 rotates generating, and the output terminal of alternator G1 connects the positive terminal of accumulator E by rectifier, and charges for accumulator E.Preferably, the full bridge rectifier that rectifier is made up of eight diode D5-D12, wherein four diode D9-D12 forward conductions, the conducting of other four diode D5-D8 negative senses, accumulator E to negative sense conducting diode between be provided with capacitor C1, capacitor C1 play intercept galvanic effect.
Further, the electric machine speed regulation controller for controlling motor speed is provided with in casing.Regulated the rotating speed of motor by electric machine speed regulation controller, thus control the rotating speed of alternator G1, alternator G1 generated energy raises with rotating speed and increases.
Automobile ignition switch S1, fuse F, diode D1, charging alarm lamp L and telefault L1 is in series with in the discharge circuit of described accumulator E, the negative pole end of accumulator E has been provided with the triode Q1 of on-off action, and the input end of triode Q1 is connected between charging alarm lamp L and telefault L1.In the discharged condition, triode Q1 conducting, electric current exports from accumulator E positive pole accumulator E, successively after automobile ignition switch S1, fuse F, diode D1, charging alarm lamp L and telefault L1, arrives the negative pole of accumulator E, and charging alarm lamp L lights.
Further, described alternator G1 is connected to the positive terminal of accumulator E after rectifier, and in addition, another output terminal of alternator G1, after the diode D2-D4 of forward conduction, is connected to the input end of triode Q1.In accumulator E normal charging process, the level at charging alarm lamp L two ends is equal, and charging alarm lamp L can not be bright; And when alternator G1 does not work or accumulator E occurs that charging is abnormal, charging alarm lamp L lights, remind car owner's circuit to occur abnormal, answer parking checking reason.
Teaching case of the present utility model not only may be used for generator connection, also can arrange the generator circuit fault that some are common, such as: generator does not generate electricity, it is very little to generate electricity, maintenance generator, allows student start to get rid of.Adopt teaching case of the present utility model to impart knowledge to students, student needs connection line of taking action on one's own, and is coupled together by each electric elements, formed automobile generator circuit.In wiring process, student more easily understands the trend of circuit, understands the principle of work of automobile current generator.After wiring completes, student understands the principle of work of automobile current generator circuit further by the running of system.
Teaching case of the present utility model has that cost is low, volume is little, lightweight advantage, is easy to carry, and can be carried into the place such as laboratory or classroom and use, the circuit of the case of this teaching simultaneously not easily generates heat, short circuit, easily repairs, safeguards, can easily for teaching.Adopt teaching case of the present utility model to impart knowledge to students, student can the very clear circuit seeing automobile current generator circuit, more easily understands its principle of work, and by allowing student start connection line, make it understand line alignment, teaching efficiency is remarkable.
