Description
Technical field
The utility model relates to the electric welding equipment technical field.
Background technology
Known electric welding machine principle is to adopt rectifier transformer system output direct current, produces high temperature through both positive and negative polarity in the bond pad locations short circuit during electric welding operation, thereby realizes welding; This electric welding machine volume is big; Heavy moves inconveniently, must have under the situation of external power source and could use; The known electric welding machine principle that need not external power source is to adopt the generating set generating, and rectification is a direct current then, and this electric welding machine volume is big, and weight is big, moves inconvenience, needs fuel filling.
Above-mentioned two kinds of electric welding machines all can't be realized the manpower transport, and are inconvenient in power free outdoor district work.
The utility model content
The utility model technical issues that need to address just are to provide a kind of portable accumulation of energy small electrical welding machine, and the utility model has solved existing electric welding machine can't realize the manpower transport, in the inconvenient problem of power free outdoor district work.
For addressing the above problem, the utility model adopts following technical scheme: the lithium ion battery group 1, battery protection circuit 2-1 and the charging circuit board 2-2 that comprise housing 5 and be installed in housing 5 inside; Lithium ion battery group 1 is made up of several lithium ion batteries 1-1 series connection; The both positive and negative polarity of lithium ion battery group 1 connects battery protection circuit 2-1, battery protection circuit 2-1 connects charging circuit board 2-2; Also have charging inlet 3 and discharge interface 4 on the housing 5, charging inlet 3 connects charging circuit board 2-2, and discharge interface 4 connects battery protection circuit 2-1.
The utility model overcomes existing electric welding machine can not portable operation, and the many defectives that can not use at the non-transformer environment.It adopts the power-type battery to make battery modules; Especially adopt lithium ion battery; Make the voltage of battery modules identical with electric welding machine voltage, combo forms the current requirements that reaches electric welding, forms the normal power of portable accumulation of energy electric welding machine; Battery protecting circuit and charging circuit are installed simultaneously, are constituted whole electric welding machine system.Whole portable electric welding machine is in light weight, and volume is little, can reach manpower and carry, and can be widely used in the outdoor emergency operation and use.
Description of drawings
Fig. 1 is the utility model structural representation.
Symbol description among the figure: lithium ion battery group 1, lithium ion battery 1-1, battery protection circuit 2-1, charging circuit board 2-2, charging inlet 3, discharge interface 4, housing 5.
The specific embodiment
As shown in Figure 1, portable accumulation of energy small electrical welding machine, the lithium ion battery group 1, battery protection circuit 2-1 and the charging circuit board 2-2 that comprise housing 5 and be installed in housing 5 inside; Lithium ion battery group 1 is made up of several lithium ion batteries 1-1 series connection, reaches the required voltage of electric welding machine after the lithium ion battery 1-1 series connection; The both positive and negative polarity of lithium ion battery group 1 connects battery protection circuit 2-1, battery protection circuit 2-1 connects charging circuit board 2-2; Also have charging inlet 3 and discharge interface 4 on the housing 5, charging inlet 3 connects charging circuit board 2-2, and discharge interface 4 connects battery protection circuit 2-1.
The utility model solves the technical scheme that its technical problem adopted: adopt the power-type lithium ion battery to be connected into the electric welding machine required voltage; The power-type capacity of lithium ion battery; Can be for satisfying the needs of electric welding electric current when the multiplying power discharging that battery allows; Can make the battery long-life like this, satisfy the little lightweight minimum requirements of capacity simultaneously.Between the both positive and negative polarity of battery, add battery protecting circuit, make battery can not cross and put, thus the protection battery.Battery protecting circuit is overcharged and crosses at battery system can break off major loop when putting, thus the protection battery; External charger is adopted in charging, and charging voltage satisfies the battery system needs, and charger can adopt current-limiting apparatus, carries out work in the floating charge process to satisfy.
When discharge, discharge interface 4 is externally emitted electric current; When charging, charging inlet 3 inserts the input of external communication civil power, can charge to lithium ion battery; The input of interchange is externally arranged; And when the output of interchange is arranged simultaneously; Regardless of discharge power and charge power; The power of lithium battery and outside input power sum are the power output sum, the input of lithium ion battery group 1, power output can be just also can be negative, through the control of battery protecting circuit and charging circuit.
The beneficial effect of the utility model is: 1, volume is little in light weight, is suitable for portable; 2, adopt holding circuit, guarantee the long-life of battery; 3, can emergency in the occasion that does not have power supply; 4, can adopt civil power to replenish easily.
Said battery protecting circuit can adopt the battery protecting circuit of prior art, and this circuit can be multistage, and a protector can be by spark gap, and piezo-resistance and semiconductor are formed.Between level and level, needing sometimes can be flux matched to reach with decoupling component.What the utility model adopted is lithium battery protection circuit; Form by two FETs and privacy protection integrated package S--8232; Overcharge control valve FET2 and overdischarge control valve FET1 is series at circuit, by protection IC monitoring battery voltage and control, when cell voltage rises to 4.2V; Additives for overcharge protection pipe FET2 ends, and stops charging.For preventing misoperation, generally be added with delay capacitor at external circuit.When battery is under the discharge condition, when cell voltage was reduced to 2.55V, overdischarge control valve FET1 ended, and stops to power to the load.Overcurrent protection is that control FET1 ends it, stops to load discharge when having big electric current to flow through in the load, and purpose is in order to protect battery and FET.
Said charging circuit can adopt the lithium ion cell charging circuit of prior art, and its principle is: adopt constant voltage to charge the battery, guarantee can not overcharge.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
