Description

The energy-efficient charger of portable multi-function

A kind of energy-efficient charger of portable multi-function that is suitable for automobile, diesel vehicle, battery vehicle, open-air working in dispersion engineering truck, power vessels high-capacity lead-acid storage battery mobile (fixing) charging usefulness belongs to the battery charger technical field.

The charging work of the large-capacity battery that current vehicle, boats and ships are used all must remove storage battery and be transported to professional storage battery maintenance from car, charging department concentrates and carries out charging work, is very much bothersome, and expensive running time is protected in waste.Mainly can not get timely boost charge meeting when being discharged or defective battery and influence useful life, vehicle launch performance, especially cold-starting difficulty has influenced vehicle operating efficient and economic benefit.

It is little that the purpose of this utility model provides a kind of volume, in light weight, power is big, charging is fast, use the peace gold reliable, be convenient to install and carry, really can satisfy multiclass long-distance transport motor vehicle diesel car, big capacity power shortage storage battery on the car is utilized the New-type charge machine that the accommodation time of stopping in time carries out the short time boost charge on the way in cold season with car.

The technical solution of the utility model is: it comprises casing, panel, transformer, electronic circuit, and characteristics are extraordinary axial flow blower to be housed carry out the wind-cooling heat dissipating cooling; The elementary winding of voltage regulating transformer adopts the multiply tap; Electronic circuit has autocontrol temperature device K overcurrent protective device M ₂With superpressure automatic safety device M ₁

Autocontrol temperature device K is serially connected in the fan power circuit of a level coil of voltage regulating transformer.

Overcurrent protective device M ₂Be connected on the dc output circuit two ends.

Superpressure automatic safety device M ₁Be connected between level coil of voltage regulating transformer and the interchange output circuit.

Fig. 1 is the utility model front view.

Fig. 2 is Fig. 1 end view.

Fig. 3 is Fig. 1 rearview.

Fig. 4 is a schematic circuit.

Sequence number 1, handle among the figure, 2, D.C. voltmeter, 3, superpressure indicator light, 4, " charging ", " pressure regulation " change over switch, 5, DC ammeter, 6, casing, 7, A.C. voltmeter, 8, alternating current-direct current regulates block switch, 9, negative terminal, 10, positive terminal, 11, extraordinary blower fan, 12,12V voltage binding post, 13, exchange accessory power outlet, 14, AC power safety box, 15, the defeated line hole of AC power, 16,6V voltage binding post, 17, the DC charging safety box, 18, air intake cover, 19, voltage regulating transformer.L is a power supply indicator, M ₁Be superpressure automatic safety device, M ₂Be overcurrent protective device, K is the autocontrol temperature device.

Below in conjunction with accompanying drawing 1---4 further specify its work.

The autocontrol temperature device is to use the thermosistor (thermal protector) of UWS type car control system to repack that reverse action formula structure finishes into.So-called reverse action formula structure is to say that general thermostat is when device temperature reaches with value in excess of the quota, the thermostat contact will disconnect cuts off the electricity supply, electroheat equipment stopped power supply reach the reduction device temperature, and the reverse action formula is when the body working temperature surpasses 45 ℃～50 ℃ limit values, its contact is not to disconnect stopping power supply, but closing of contact energising makes blower fan running work.Reach heat radiation and reduce organism temperature, when organism temperature dropped to safety value, reverse action thermostat contact disconnected and cuts off fan power.Blower fan is for exchanging or the miniature extraordinary axial flow blower of direct current.

At the deisgn product heart component---when rectification, voltage regulating transformer winding at different levels, be bold in innovation, take to utilize the tap of the little electric current winding of primary multiply to regulate, reach the output voltage and the power output of the secondary big current commutates winding of change, so not only guaranteed the fastness of transformer windings at different levels, and it is different because of operating position with AC voltage adjusting to separate the transformer rectification charging inferior, both can not dual-purpose conflicting, make existing large current charge power, the high power AC voltage regulation function is arranged again.

These series of products model, charging, pressure regulating performance wind subordinate list.

Major advantage of the present utility model is: 1, aesthetic in appearance, and compact conformation, circuit uniqueness, electricity Source side just. 2, volume is little, in light weight, shock resistance strong, portably use convenience with car. Gold machine weight Be respectively 1 type 8.8kg, 2 type 6.8kg, 3 type 4.8kg, volume only has common with the single charging merit of power 1/4 of energy charger volume. 3, power output is big, charging is fast, charging current can reach 12---15A, More than charging rate is more fast again than common simple function charger. Can in time mend in transit Charging makes battery often be in the full charge state, can prolong battery and starter life-span one Doubly. But each car cost saving in every year is more than 400 yuan, and 10,000 ten thousand cars of Jin Ri are with 1/2 car Calculating, but 16,000,000,000 yuan of cost savings in every year. Also can improve the economic benefits of transportation efficiency. 4, this practicality is new The type operating temperature is low, the peace gold is reliable. At big electric current (15 peace), (12 volt of 195 big capacity of ampere-hour at full capacity Battery), under long-time (48 hours) charging operating position, only 30 ℃ of body temperatures---38 ℃, silicon The rectifier cell temperature is at 38 ℃---between 42 ℃, casing temperature and ambient temperature be almost equal. 5, originally Utility model except having energy-efficient charge function, also have AC voltage adjusting function, a tractor serves several purposes.
