Description

A kind of USB cycle chargings constant pressure exports lithium battery

Technical field

It the utility model is related to a kind of lithium battery, and in particular to a kind of USB cycle chargings constant pressure exports lithium battery.

Background technology

Traditional No. 5/No. 7 batteries are widely used in all kinds of digital electronic goods, and usage quantity is huge, conventional alkaline cell Can only be disposable, electricity can only fall to abandon using after complete；1.2 traditional V Ni-MH batteries can be used with cycle charging, but not It can realize that the V. firm powers of constant pressure 1.5 export, and need special charger to charge in charging, this results in people and gone out Just needed during travel row with many chargers, and special charger is it is easy to forget that carrying and losing.

The content of the invention

Technical problem to be solved in the utility model is to provide a kind of rechargeable battery with USB interface, as long as carrying The MICRO USB charging wires of one routine, no matter family expenses or out of town trip, in the USB port of charger for mobile phone/apparatus such as computer Can charges, simple and convenient, it is not necessary to special charger；And this product can also realize that the V. firm powers of constant pressure 1.5 are defeated Go out.

The utility model is achieved through the following technical solutions：A kind of USB cycle chargings constant pressure exports lithium battery, bag A shell, battery, pcb board and the USB charging inlets being arranged on pcb board are included, the USB charging inlets are arranged at shell On, the pcb board has 1.5 V constant pressure output protection circuits, and the USB charging inlets are electrically connected in 1.5 V constant pressures On the pcb board of output protection circuit, charged by USB charging inlets for battery.

As preferable technical scheme, the both ends of shell are the both positive and negative polarity of battery, and a dividing plate is set among enclosure, Whole shell divide is arranged in control chamber by dividing plate into battery cavities and control chamber, pcb board, and battery is arranged at battery cavities It is interior.

As preferable technical scheme, the 1.5 V constant pressures output protection circuit has a charging management chip and one Constant voltage discharge managing chip.

As preferable technical scheme, pcb board is installed on one side and covered among the fixed support of setting, the cover sealing The outer openings end of whole shell, cathode metal contact are arranged on the cover.

As preferable technical scheme, status indicator lamp is additionally provided with the pcb board.

As preferable technical scheme, battery is polymer lithium battery core, has the output of 1.5 V firm powers.

The beneficial effects of the utility model are：The utility model has the rechargeable battery of USB interface, as long as carrying one often The MICRO USB charging wires of rule, no matter family expenses or out of town trip, the can in the USB port of charger for mobile phone/apparatus such as computer Charging, it is simple and convenient, it is not necessary to special charger；

And this product can also realize that the V. firm powers of constant pressure 1.5 export, and be protected all the time from beginning to use to electricity to exhaust Same Efficieney output is held, in electronic class and to be wirelessly transferred usage experience effect in electronic product most preferable；Battery uses polymerization Thing lithium cell compared with disposable battery, repeatedly cycle charging can not only use, and raw material is sharp as main energy storage material It is high with rate, die-away time length, battery rubbish is greatly reduced, meets environmentally friendly concept environmental protection.

Brief description of the drawings

, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work Under, other accompanying drawings can also be obtained according to these accompanying drawings.

Fig. 1 is the circuit theory diagrams of the utility model pcb board；

Fig. 2 is overall structure diagram of the present utility model；

Fig. 3 is the structural representation of cover of the present utility model.

Embodiment

All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive Feature and/or step beyond, can combine in any way.

This specification（Including any accessory claim, summary and accompanying drawing）Disclosed in any feature, except non-specifically chatting State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature It is an example in a series of equivalent or similar characteristics.

As Figure 1-Figure 2, including a shell 4, battery 1, pcb board and the USB charging inlets being arranged on pcb board 3, USB charging inlets 3 are arranged on shell, and pcb board has 1.5 V constant pressure output protection circuits, and USB charging inlets 3 electrically connect It is connected on the pcb board with 1.5 V constant pressure output protection circuits, is charged by USB charging inlets 3 for battery.

Wherein, the both ends of shell are the both positive and negative polarity of battery, and a dividing plate 2 is set among enclosure, and dividing plate 2 will be entirely outer Shell is divided into battery cavities and control chamber, and pcb board is arranged in control chamber, and battery 1 is arranged in battery cavities.

1.5 V constant pressures output protection circuits have a charging management chip and a constant voltage discharge managing chip.Charge shape During state, charging management chip is started working in 1.5 V constant pressure output protection circuits, and carrying out constant current constant voltage to polymer lithium battery core fills Electricity, LED is bright in charged state, when polymer lithium battery core voltage be charged to 4.2V it is at full charge when LED go out, charging complete；Put During electricity condition, the decompression constant voltage discharge managing chip in 1.5 V constant pressure output protection circuits is started working, polymer lithium battery core electricity Pressure（Lithium voltage 3.6V-4.2V）By discharge manage chip voltage after in battery bottom negative pole end and battery top positive terminal constant pressure 1.5 V are exported, realize that the V. firm powers of constant pressure 1.5 export, polymer lithium battery core voltage drops to 2.5V during use of discharging When battery stop electric discharge, dead battery capability.
