With reference to Fig. 4, this novel power supply case still can adopt the conventional charging circuit that uses to storage battery 3 chargings.Its electric control principle process is as follows: when external AC or DC power supply charged, electric current was by emitter → Q1 collector electrode → diode D1 → two section switch 70 → power supply protector 72 → storage battery 3, the then LED of resistance R 1 → triode Q1
574 flickers, expression is charged; After storage battery 3 power supplys were full of, electric current made the Q3 conducting by the base stage of collector electrode → triode Q3 of emitter → Q2 of triode Q2, and then electric current makes two sections switch 70(be subjected to relay J 60 controls through relay J 60) go to F point, then LED by the E point
574 is permanent bright, LED
675 is luminous, voltage indicator 5 work instructed voltage values.Extended line socket 8 can provide external equipment electric power, and simultaneously three sections switches 71 can select light 42 to make illuminating lamp, warning lamp or do not work; When storage battery 3 power supplys consume gradually because of external load, when voltage drops to below 10 volts, LED
776 is luminous, and this has charged expression storage battery 3.
With reference to Fig. 5, also be equipped with in the control circuit of this novel power supply case (plate) 6 by commonly used multi-resonant oscillating circuit 61(such as TIP35C integrated package) and shaping circuit (comprise back half-wave circuit 62＜also available integrated package〉and before the integrated package of available routine of half-wave circuit 63＜also) inverter circuit formed, make it to consist of and have the circuit structure that alternating current-direct current is imported and exported.Its circuit connects as follows: socket 80 links with two of transformer 33 primary coils, multi-resonant oscillating circuit 61(integrated package in inverter circuit), the centre cap a ' of its feeder ear (electrical input) a and transformer 33 secondary coils joins, its two ac output end b and c respectively with shaping circuit in back half-wave circuit 62(integrated package) and preceding half-wave circuit 63(integrated package) input b ' and c ' join, then the output d of half-wave circuit 62 and preceding half-wave circuit 63 and e then join with two of transformer 33 secondary coils respectively.Its electric control principle process is as follows: socket 80 can enter for external AC power supplies, rectification after transformer 33 transformations, if charge switch 7 is set in the G point, this power supply will charge to storage battery 3; On the contrary, if charge switch 7 is set in the H point, then the DC power supply of storage battery 3 will through oscillating circuit 61 → back half-wave circuit 62 and before half-wave circuit 63 → transformer 33 → socket 80, make socket 80 exportable AC power supplies, while LED
877 with luminous, represents socket 80 to have AC power supplies to exist, and makes this power supply box realize having the particularly structure of output of AC, DC input.The adjustable resistance VR in the multi-resonant oscillating circuit 61 of Fig. 5 in addition
164 and adjustable resistance VR
265 frequencies that can adjust this output AC power supplies are 50-60HZ.
In Fig. 6, when the voltage of input is 12 volts, each Zener diode (promptly having played the voltage stabilizing didoe of pressure limiting effect) Z
166, Z
267, Z
368 and Z
469 all are in collapse district (being the avalanche region) work, and the resistance value minimum makes LED
150, LED
251, LED
352 and LED
453 is all luminous, and the expression power supply is 12 volts sufficient quantity; When the voltage of input is 11 volts, Z
166 enter active region work, and resistance value increases and forms off state, then LED
150 do not work, surplus 11 volts of expression electric weight; When the voltage of input is 10 volts, Z
267 also enter active region work, make LED
251 also do not work, only surplus 10 volts of expression voltages; When the voltage of input is 9 volts, Z
368 also enter active region work, make LED
352 also do not work, only surplus 9 volts of expression electric weight; When the voltage of input is lower than 9 volts, Z
469 also enter active region work, make LED
453 also do not work, and this has carried out charging work then to represent storage battery 3.
Use the improved power supply box of the utility model to have following effect:
1, can utilize the input carrying out of AC power supplies or DC power supply charge in batteries, also exportable AC power supplies or DC power supply.
2, AC power supplies can be exported by socket, and the DC power supply is then exported by the extended line socket.
3, if desire long-time external another the storage battery of available charging clamp that uses, then has splendid extendibility than the large power supply capacity.
4, storage battery and transformer are arranged in the power supply room of left and right casing, and this position just is positioned at the handle below, forms the steadily of centre of gravity effect.
The effect that has kept original multi-functional portable power supply box in addition: have the storage that voltage indicator can demonstrate battery feed, judge whether that for the user is very easy this carries out charging work; Have LED5, LED6 and LED7, can indicate the charging working condition of storage battery, LED8 can indicate the output state of AC power supplies simultaneously; Have by three sections warning lamp or lasting luminous work light effects that the controlling switch lamp bubble is interrupted luminous; Have the first aid plug, the first aid when exportable battery feed steam supply car starts is used; Have reflector plate, form alarm function; Have spare bulb and fuse, can be when accident is damaged for replacing.
