Particularly, described electric weight shows that LED lamp group is made up of 6 LED lamps, along with the electric weight increase is lighted or the electric weight minimizing is extinguished successively successively.
Particularly, described back-up source inside is provided with overcurrent/short-circuit protection, and described overcurrent/short-circuit protection is connected between lithium battery and the described output interface.
Particularly, described back-up source inside is provided with the over-charge protective device, and described over-charge protective device is connected between lithium battery and the described charging input interface.
Compared with prior art, the back-up source that the utility model provides, two kinds of inputs of charger and solar panels charging modes is provided, USB output and two kinds of way of outputs of DC direct current output, 6 kinds of voltage outputs are provided during DC output, and can select as required to select output voltage automatically or manually select output voltage, use flexibly thereby satisfy the multiple mode of multiple electronic product.Discharge and recharge simultaneously and use, strengthened user's up duration.9 LED lamps can show the work at present state in real time, in time remind the user, built-in over-charge protective device and overcurrent protective device, thus improved life-span, ease for use and the security reliability of back-up source.
By following description also in conjunction with the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used to explain embodiment of the present utility model.
Description of drawings
The structural representation of a kind of back-up source embodiment that Fig. 1 provides for the utility model.
Fig. 2 is the overcurrent/short-circuit protection of back-up source as shown in Figure 1 and the structural representation of the circuit theory that the over-charge protective device connects.
Embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, the similar elements label is represented similar elements in the accompanying drawing.As mentioned above, as depicted in figs. 1 and 2, the back-up source that the utility model provides (1) is rectangular shape, is disposed with charging input interface (2), switch key (10), electric weight demonstration LED lamp group (3), automatic scan LED lamp (6), manual scanning LED lamp (5), power supply indication LED lamp (4), DC output interface (7), manual voltage-selected switch (8) and USB output interface (9) at described cuboid end face.
Described charging input interface (2) is the DC input interface, can use the adapter collocation AC adapter in the 16V-20V scope to charge, and the joint categories of acceptance has YL01, YL53, YL54 and YL61.
Described electric weight shows that LED lamp group 3 is made up of 6 LED, be followed successively by the LED4-LED9 of label for (31)-(36), when back-up source (1) begins to insert charging from electroless state, LED4 (31) begins flicker, other are in and extinguish state, when electric core voltage reaches 3.75V, LED4 (31), LED5 (32) begins horse race, all the other continue to extinguish, the rest may be inferred, and electric core voltage reaches 3.85V, 3.95V, 4.05V, 4.15V the time, LED6 (33), LED7 (34), LED8 (35), LED9 (36) adds horse race successively, when charging reached 100%, 6 LED lamps of LED lamp group (3) were bright entirely.After stopping power supply input, all LED stop shinnyly behind the 5s, and MCU enters resting state.Back-up source is from completely establishing when discharge beginning by cable, and LED9-LED4 extinguishes successively, and electric core voltage is during less than 3.1V, LED4 (31) flicker and buzzer warning, and during less than 2.9V, all LED all extinguish and stop discharge.
Described DC output interface (7) can provide 6 kinds of output voltages, be respectively 10V, 12V, 15V, 16 V, 18V, 20V, before the charging beginning, can select manually to select output voltage or select output voltage automatically by manual voltage-selected switch 8, electric weight shows 6 LED lamps correspondence indication of corresponding 6 output voltages successively of LED lamp group (3).When selecting manual mode to select output voltage, manual scanning lamp (5) begins flicker, uses switch key (10) can select suitable voltage, latch voltage after 3 seconds.When selecting automatic mode to select output voltage, automatic scan lamp (6) begins flicker, can external equipment be charged the suitable output voltage of automatic scan after pressing switch key (10).
